Description

Cell transfer and loading equipment and cell transfer and loading system

Technical Field

The present invention relates to the technical field of battery cell production, and in particular to battery cell transport and loading equipment and a battery cell transport and loading system.

Background Art

In the process of producing solar cells, the cells are placed in boats for circulation and processing. The production process of solar cells involves multiple processes. When processing cells with specific processes, the cells need to be placed in specific boats. For example, when laser etching is performed, the cells are placed in a special boat; when boron diffusion is performed, the cells are placed in another special boat. Therefore, in the process of producing solar cells, it is necessary to transfer cells in one boat to another boat.

At present, there are battery transfer and loading devices that transfer battery cells in one container (one of the boat and the flower basket) to another container (the other of the boat and the flower basket). The process of these battery transfer and loading devices to transfer and load battery cells from one container to another container is usually as follows: first, the first container is flipped from a vertical state to a horizontal state, and then the first top sheet is raised and passed through the first container to lift up the battery cells in the first container, and then the lifted battery cells are grasped by a suction cup unit containing multiple suction cups, and then the suction cup unit is horizontally moved to the top of the second container, and then the second top sheet is raised and passed through the second container in a horizontal state, and the suction cup unit releases the battery cells to place the battery cells in the second top sheet, and then the second top sheet is lowered to place the battery cells in the second container. In this process, the battery cells are first transferred from the first container to the first top sheet, then from the first top sheet to the suction cup unit, then from the suction cup unit to the second top sheet, and then from the second top sheet to the second container. However, the battery cell may move relative to the suction cup while following the horizontal movement of the suction cup, resulting in a large positional offset of the battery cell, which reduces the positioning accuracy of the battery cell and is not conducive to accurately placing the battery cell into the second container.

Summary of the invention

Based on this, it is necessary to provide a battery cell transfer and loading device and a battery cell transfer and loading system to address the above problems. The battery cell transfer and loading device does not involve horizontal movement of the battery cell during the process of transferring the battery cell, which is beneficial to prevent the battery cell from having a large positional offset and can improve the positioning accuracy of the battery cell.

In order to solve the above problems, the present invention provides the following technical solutions:

A battery cell transfer and loading device is used to transfer battery cells in a first boat to a second boat, and the battery cell transfer and loading device comprises:

frame;

A suction cup unit is liftably located directly above the frame, and the space between the frame and the suction cup unit is a loading and unloading space;

A switchboard, movably arranged on the frame;

Two boat clamping devices, respectively used to clamp the first boat and the second boat, the two boat clamping devices are rotatably arranged on the switching platform, and the switching platform moves the two boat clamping devices to the loading and unloading space in sequence; and

The top piece is liftably located directly below the suction cup unit and acts on the battery sheet to push the battery sheet out of the first boat or into the second boat; the suction cup unit can absorb the battery sheet lifted by the top piece.

The battery cell transport and loading equipment has at least the following beneficial effects:

The battery cell transfer loading device transfers the battery cells in the first boat to the second boat in a process as follows: first, the top sheet is located directly below the loading and unloading space, and the first boat carrying the battery cells is clamped in a boat clamping device; the boat clamping device clamping the first boat is turned over to make the first boat in a horizontal state and the first boat is located in the loading and unloading space. Then, the top sheet is raised to lift the battery cells in the first boat, and at the same time, the empty second boat is clamped in another boat clamping device, and the boat clamping device clamping the second boat is turned over to make the second boat in a horizontal state. Then, the suction cup unit sucks the battery cells lifted by the top sheet. Then, the top sheet is lowered to directly below the loading and unloading space; the switching table is moved to make the first boat leave the loading and unloading space and move the second boat into the loading and unloading space. Then, the top sheet is raised so that the top sheet supports the battery cells; the suction cup unit releases the battery cells to put the battery cells into the top sheet. Then, the top sheet is lowered to put the battery cells into the second boat. By using the battery cell transfer loading device to transfer the battery cells in the first boat to the second boat, the battery cells are prevented from moving horizontally following the suction cups, which is beneficial to prevent large positional deviations of the battery cells and can improve the positioning accuracy of the battery cells, thereby facilitating the transfer of the battery cells to the second boat.

Moreover, in the conventional battery cell transfer and loading equipment, in order to ensure that the battery cell can follow the horizontal movement of the suction cup, the suction cup needs to apply a large suction force to the battery cell. In order to prevent the battery cell from being greatly offset in the process of following the horizontal movement of the suction cup, the suction cup usually moves horizontally slowly at a low speed, which reduces the efficiency of transferring the battery cell. The battery cell transfer and loading equipment provided by the present invention improves the efficiency of transferring the battery cell because it avoids the battery cell following the horizontal movement of the suction cup, and the suction cup unit does not need to apply a large force to the battery cell, which is conducive to reducing the use cost.

In addition, compared to the battery cell transfer and loading equipment in the traditional technology that needs to be provided with two top sheets, the battery cell transfer and loading equipment provided by the present invention only needs to be provided with one top sheet, which can not only simplify the structure of the battery cell transfer and loading equipment, but also reduce the cost of use. Moreover, when installing the traditional battery cell transfer and loading equipment, it is necessary to align the first top sheet with the first container, and align the second top sheet with the second container, and two alignments are required. On the one hand, this makes the installation cumbersome, and on the other hand, there are many structures that need to be aligned, the risk of alignment failure increases, and the overall stability and reliability of the equipment are poor. When installing the battery cell transfer and loading equipment provided by the present invention, it is only necessary to align the top sheet with the suction cup unit, and only one alignment is required, which is convenient for installation, and the overall stability and reliability of the equipment are relatively high.

In one embodiment, the switch table is slidably connected to the frame, and the two boat clamping devices are arranged in sequence along the sliding direction of the switch table.

With such arrangement, the boat clamping device can be moved in and out of the loading and unloading space by sliding the switching table.

In one embodiment, the battery cell transport and loading equipment further includes a correction mechanism, which is located in the loading and unloading space; the correction mechanism includes:

A first driving assembly includes a first power output member, wherein the first power output member is connected to the frame and is movable in a horizontal direction;

The mounting assembly includes a mounting seat, the mounting seat is provided with a plurality of mounting positions, and the plurality of mounting positions are sequentially distributed along the moving direction of the first power output member; and

The return piece, the mounting assembly and the first driving assembly are each provided with two return pieces, and are arranged one by one; each mounting seat is fixedly mounted on the corresponding first power output member, and each return piece is detachably locked on a mounting position on the corresponding mounting seat; the two return pieces are arranged opposite to each other, and under the drive of the corresponding first power output member, the two return pieces approach each other or move away from each other along the horizontal direction.

With such arrangement, the two correcting members can be moved toward each other, so that the two correcting members respectively abut against the two sides of all the battery cells, so that the same side of all the battery cells are aligned, and the position of the battery cells is corrected, so that the battery cells can be conveniently placed in the second boat, and the battery cells can be prevented from being damaged during the process of being placed in the second boat. Moreover, the correcting members can be installed in different installation positions, so as to adjust the initial position of the correcting members and the initial spacing between the two correcting members, so that the correcting mechanism is suitable for the correction of battery cells of different specifications.

In one embodiment, the opposite sides of the two return members are clamping sides, and the clamping sides are planar. A plurality of first partitions are fixedly provided on each clamping side at equal intervals along the horizontal direction. A first gap is formed between two adjacent first partitions on each return member. The first gap on one of the return members corresponds to the first gap on the other return member one by one to form a space for accommodating one of the battery cells. Along the direction perpendicular to the clamping sides, the distance between two adjacent first partitions first decreases and then increases.

With such arrangement, when the correction mechanism corrects the position of the battery cell, each battery cell enters the corresponding first gap respectively, and the two first separators forming the first gap can play a role in limiting the position of the battery cell. In this way, the clamping side and the two adjacent first separators thereon respectively correct the battery cell from three sides of a battery cell, which is conducive to improving the correction effect of the correction mechanism. Moreover, the battery cell and the first separator are in point contact or line contact, and the contact area between the battery cell and the first separator is small, which is conducive to preventing the battery cell from being damaged by large friction with the first separator.

In one embodiment, the boat clamping device includes a boat clamping mechanism, the boat clamping mechanism includes a boat supporting platform and a boat clamping structure, the top side of the boat supporting platform is used to place the boat, the boat clamping structure includes a second drive assembly and a boat clamping member, the second drive assembly includes a second power output member, and the second power output member can be slidably arranged on the bottom side of the boat supporting platform along the horizontal direction; the boat clamping member is located above the boat supporting platform, connected to the second power output member, and can move along the thickness direction of the boat supporting platform; the boat clamping member and the second drive assembly are each provided with two and are arranged one to one, and the two boat clamping members are arranged opposite each other.

In this way, the two boat clamping members can be moved simultaneously along the thickness direction of the boat support platform, so that the positions of the two boat clamping members can be changed, thereby adjusting the clamping position. According to the thickness of the base of the clamped boat, the two boat clamping members are synchronously moved along the thickness direction of the boat support platform to the optimal clamping position or near the optimal clamping position, and then the two second driving components drive the two boat clamping members to move toward each other until the two boat clamping members abut against the two sides of the boat base, so that the boat can be stably clamped.

In one embodiment, the battery cell transfer and loading equipment includes two boat turning mechanisms arranged on the switching table, the boat turning mechanism includes a second rotating shaft, a second transmission member and a fifth drive assembly, the fifth drive assembly includes a fifth seat body and a fifth power output member, the fifth seat body is rotatably connected to the switching table, the fifth power output member is slidably connected to the fifth seat body, the second transmission member is rotatably connected to the fifth power output member and fixedly connected to the second rotating shaft, and the second rotating shaft is rotatably connected to the switching table; the boat turning mechanism and the boat clamping device are arranged one by one, and the boat supporting platform of each of the boat clamping devices is fixedly arranged on the second rotating shaft corresponding to the boat turning mechanism.

In this arrangement, when the fifth power output member slides, the fifth seat body rotates relative to the switching table, the second transmission member rotates relative to the fifth power output member and drives the second rotating shaft to rotate, thereby driving the boat supporting platform to rotate, and then driving the boat clamped by the two boat clamping members to rotate, thereby flipping the boat to a horizontal state or a vertical state.

The present invention also provides a battery cell transport and loading system, the battery cell transport and loading system comprising:

The above-mentioned battery cell transfer and loading equipment;

a placing table, spaced apart from the frame or fixed to the frame, for placing the first boat and the second boat; and

The transport mechanism is spaced apart from the frame or fixed to the frame, and can transport the first boat from one of the placement table and a boat clamping device to the other, and can transport the second boat from one of the placement table and another boat clamping device to the other.

The transport mechanism can transport the first boat carrying the battery cells to a boat clamping device, and after the battery cells in the first boat are removed, the empty first boat is transported to the placement table by the boat clamping device; the transport mechanism can also transport the empty second boat to another boat clamping device, and after the battery cells are moved into the second boat, the second boat carrying the battery cells is transported to the placement table by the boat clamping device. Because the battery cell transport and loading system includes the above-mentioned battery cell transport and loading equipment, the battery cell transport and loading system has the technical effect of the above-mentioned battery cell transport and loading equipment.

The present invention also provides a battery cell transport and loading method, which is used for the above-mentioned battery cell transport and loading equipment, and the battery cell transport and loading method comprises the steps of:

This battery cell transfer and loading method avoids the battery cell following the horizontal movement of the suction cup, which is beneficial to prevent the battery cell from having a large positional offset, and can improve the positioning accuracy of the battery cell, thereby facilitating the transfer of the battery cell to the second boat. Also, because the battery cell is prevented from following the horizontal movement of the suction cup, the suction cup unit does not need to exert a large force on the battery cell, which is beneficial to reducing the cost of use. This method only requires one top sheet, which can not only simplify the structure of the corresponding battery cell transfer and loading equipment, but also reduce the cost of use.

In one embodiment, before lowering the top sheet to place the battery sheet into the second boat, the following steps are also included:

The two correcting parts of the correcting mechanism are moved closer to each other to correct the position of the battery cell; after the position of the battery cell is corrected, the two correcting parts of the correcting mechanism are moved away from each other.

In one embodiment, before the suction cup unit sucks the battery sheet lifted by the top sheet, the following steps are also included:

The two correcting parts of the correcting mechanism are moved closer to each other to correct the position of the battery cell; after the position of the battery cell is corrected, the two correcting parts of the correcting mechanism are moved away from each other.

With such an arrangement, the battery cell can be accurately inserted into the suction cup unit, thereby preventing the battery cell from being damaged in the process of entering the suction cup unit.

Referring to Fig. 1, the first boat 400 is a boat for loading battery cells in the process of processing battery cells by the former process, and the second boat 500 is a boat for loading battery cells in the process of processing battery cells by the latter process. After processing the battery cells by the former process and before processing the battery cells by the latter process, the battery cells in the first boat 400 need to be transferred to the second boat 500.

Referring to FIG. 1 and FIG. 2 , the present invention first provides a battery cell transport loading device 100, which is used to transfer the battery cells in the first boat 400 to the second boat 500. The battery cell transport loading device 100 includes a frame 1, a suction cup unit 2, a switching table 4, two boat clamping devices 3 and a top piece 5. The suction cup unit 2 can be raised and lowered and is located directly above the frame 1, and the space between the frame 1 and the suction cup unit 2 is a loading and unloading space. The switching table 4 can be movably arranged on the frame 1. The two boat clamping devices 3 are used to clamp the first boat 400 and the second boat 500 respectively. Both of the two boat clamping devices 3 are rotatably arranged on the switching table 4, and the switching table 4 moves the two boat clamping devices 3 to the loading and unloading space one after another. The top piece 5 can be raised and lowered and is located directly below the suction cup unit 2, which acts on the battery cells to push the battery cells out of the first boat 400 or put them into the second boat 500. The suction cup unit 2 can absorb the battery cells lifted by the top piece 5.

The cell transfer loading device 100 transfers the cells in the first boat 400 to the second boat 500 in the following process: first, the top sheet 5 is located directly below the loading and unloading space, and the first boat 400 carrying the cells is clamped in a boat clamping device 3; the boat clamping device 3 clamping the first boat 400 is turned over to make the first boat 400 in a horizontal state and the first boat 400 is located in the loading and unloading space. Then, the top sheet 5 is raised to lift the cells in the first boat 400, and at the same time, the empty second boat 500 is clamped in another boat clamping device 3, and the boat clamping device 3 clamping the second boat 500 is turned over to make the second boat 500 in a horizontal state. After that, the suction cup unit 2 sucks the cells lifted by the top sheet 5. Then, the top sheet 5 is lowered to directly below the loading and unloading space; the switching table 4 is moved to make the first boat 400 leave the loading and unloading space and move the second boat 500 into the loading and unloading space. Afterwards, the top sheet 5 is raised to hold the battery cell; the suction cup unit 2 is made to release the battery cell to place the battery cell in the top sheet 5. Then, the top sheet 5 is lowered to place the battery cell in the second boat 500. By using the battery cell transfer loading device 100 to transfer the battery cells in the first boat 400 to the second boat 500, the battery cells are prevented from moving horizontally following the suction cup 21, which is beneficial to prevent the battery cells from being greatly offset, and can improve the positioning accuracy of the battery cells, thereby facilitating the transfer of the battery cells to the second boat 500.

Moreover, in the conventional cell transfer and loading equipment, in order to ensure that the cell can follow the horizontal movement of the suction cup, the suction cup needs to apply a large suction force to the cell. In order to prevent the cell from being greatly offset in the process of following the horizontal movement of the suction cup, the suction cup usually moves horizontally slowly at a low speed, which reduces the efficiency of transferring the cell. The cell transfer and loading equipment 100 provided by the present invention improves the efficiency of transferring the cell because it avoids the cell following the horizontal movement of the suction cup 21, and the suction cup unit 2 does not need to apply a large force to the cell, which is conducive to reducing the cost of use.

In addition, compared to the battery cell transfer and loading equipment 100 in the conventional technology which needs to be provided with two top sheet members 5, the battery cell transfer and loading equipment 100 provided by the present invention only needs to be provided with one top sheet member 5, which can not only simplify the structure of the battery cell transfer and loading equipment 100, but also reduce the use cost. Moreover, when installing the conventional battery cell transfer and loading equipment, it is necessary to align the first top sheet member with the first container, and align the second top sheet member with the second container, and two alignments are required. On the one hand, this leads to cumbersome installation, and on the other hand, there are many structures that need to be aligned, the risk of alignment failure increases, and the overall stability and reliability of the equipment are poor. When installing the battery cell transfer and loading equipment 100 provided by the present invention, it is only necessary to align the top sheet member 5 with the suction cup unit 2, and only one alignment is required, which is convenient for installation, and the overall stability and reliability of the equipment are relatively high.

It can be understood that a plurality of gaps are evenly spaced in the first boat 400 and the second boat 500, and each gap accommodates a battery cell, so the battery cells are evenly spaced. Typically, the first boat 400 and the second boat 500 are the same in shape and size.

Referring to FIG. 2 and FIG. 3 , the top sheet 5 includes a top sheet portion 51 and multiple rows of second separators 52 fixedly arranged on the top side of the top sheet portion 51 , and the multiple rows of second separators 52 are parallel to each other. The multiple second separators 52 in each row of second separators 52 are evenly spaced along the horizontal direction, and a third gap 53 is formed between two adjacent second separators 52 in each row of second separators 52 , wherein the third gap 53 in one row of second separators 52 is arranged one-to-one with the third gap 53 in another row of second separators 52 and forms a space for accommodating a battery cell. When the top sheet 5 rises, the second separators 52 are misaligned with the battery cells. As the top sheet 5 rises, each battery cell first enters the corresponding third gap 53, and then contacts the top sheet portion 51 and is gradually lifted up by the top sheet portion 51 .

Exemplarily, the frame 1 includes a vertically arranged first slide rail, the top piece 5 includes a first slide table adapted to the first slide rail, and the first slide rail and the first slide table are slidably matched so that the top piece 5 can be raised and lowered on the frame 1. Preferably, the first slide rail and the first slide table participate in forming a linear module.

In other embodiments, the top sheet 5 may also be spaced apart from the rack 1. For example, the cell transport and loading system further includes a lifting mechanism, the base of the lifting mechanism and the rack 1 are fixed to the ground at intervals, and the top sheet 5 is fixed on the lifting structure of the lifting mechanism. The lifting mechanism may be a lifting mechanism already existing in the prior art, which will not be described in detail here.

2 and 4, the suction cup unit 2 includes a plurality of suction cups 21 equally spaced in the horizontal direction, and a fourth gap 211 for accommodating a battery cell is formed between two adjacent suction cups 21. When the battery cell enters the suction cup unit 2, the battery cell is misaligned with the suction cup 21, and each battery cell can enter the corresponding fourth gap 211.

1 , the suction cup unit 2 and the frame 1 are spaced apart. In other embodiments, the suction cup unit 2 can also be directly fixed to the frame 1 .

1 , the switch table 4 is slidably connected to the frame 1, and two boat clamping devices 3 are sequentially arranged along the sliding direction of the switch table 4. In this way, by sliding the switch table 4, the boat clamping devices 3 can be moved in and out of the loading and unloading space.

Exemplarily, referring to FIG. 1 , the rack 1 includes a second slide rail 11, the switch table 4 includes a second slide table 41 adapted to the second slide rail 11, and the second slide rail 11 and the second slide table 41 form a sliding fit so that the switch table 4 is slidably connected to the rack 1. Preferably, the second slide rail 11 and the second slide table 41 participate in forming a linear module. Further, the rack 1 also includes a secondary slide rail 12 parallel to the second slide rail 11, the switch table 4 also includes a secondary slide table adapted to the secondary slide rail 12, and the switch table 4 is mounted on the second slide rail 11 and the secondary slide rail 12, which is conducive to the smooth sliding of the switch table 4.

In other embodiments, the switch table 4 is rotatably connected to the frame 1, and the two boat clamping devices 3 are arranged in sequence along the first circumference, and the center of the first circumference is located at the rotation axis of the switch table 4. In this way, by rotating the switch table 4, the boat clamping devices 3 can be moved in and out of the loading and unloading space.

The portion of the switching platform 4 located directly below the suction cup unit 2 is provided with an escape hole for the top sheet 5 to pass through.

In the process of the top piece 5 lifting the battery cell, the battery cell may have a small positional offset, which usually does not cause the battery cell to be unable to be moved into the second boat 500. However, in order to conveniently place the battery cell into the second boat 500 and prevent the battery cell from being damaged during the process of placing it into the second boat 500, it is possible to consider setting a correction mechanism 6 to correct the position of the battery cell so that the same side of all the battery cells are aligned. Referring to FIG. 2 , the battery cell transport loading device 100 also includes a correction mechanism 6, which is located in the loading and unloading space. The correction mechanism 6 includes two correction members 61 arranged opposite to each other, and the two correction members 61 can move closer to or farther away from each other in the horizontal direction. In this way, the two correction members 61 can be moved toward each other, so that the two correction members 61 respectively abut the two sides of all the battery cells, so that the same side of all the battery cells are aligned, and the position of the battery cells is corrected, so that it is convenient to move the battery cell into the suction cup unit 2 and prevent the battery cell from being damaged during the process of placing it into the suction cup unit 2.

Referring to FIG. 6 , the correction mechanism 6 includes two first drive components 64, each of which includes a first power output member 642, which is connected to the frame 1 and can move in the horizontal direction. The correction member 61 is arranged in a one-to-one correspondence with the first drive component 64, and each correction member 61 is fixed to the corresponding first power output member 642. In this way, the correction member 61 can be driven to move horizontally by the horizontal movement of the first power output member 642 to achieve correction. Moreover, by changing the preset displacement of the first power output member 642, the correction mechanism 6 can be applied to the correction of battery cells of different specifications.

In some embodiments, the return member 61 is screwed/clipped/welded to the first power output member 642 .

Referring to FIG. 2 and FIG. 6 , the correction mechanism 6 also includes two mounting components 65, each of which includes a mounting seat 651, and a plurality of mounting positions 6511 are provided on the mounting seat 651, and the plurality of mounting positions 6511 are sequentially distributed along the moving direction of the first power output member 642. The correction member 61, the mounting component 65 and the first driving component 64 are arranged in a one-to-one correspondence. Each mounting seat 651 is fixed to the corresponding first power output member 642, and each correction member 61 is detachably locked to a mounting position 6511 on the corresponding mounting seat 651. Driven by the corresponding first power output member 642, the two correction members 61 approach each other or move away from each other in the horizontal direction. In this way, the correction member 61 can be installed in different mounting positions 6511, thereby adjusting the initial position of the correction member 61 and the initial spacing between the two correction members 61, so that the correction mechanism 6 is suitable for the correction of battery cells of different specifications. The initial position refers to the position of the return member 61 when the first power output member 642 of the corresponding first driving assembly 64 is reset, and the initial spacing refers to the spacing between the two return members 61 when both first power output members 642 are reset.

It is worth mentioning that installing the correcting member 61 at different installation positions 6511 and changing the preset displacement of the first power output member 642 can both make the correcting mechanism 6 suitable for the correction of battery cells of different specifications. Combining these two methods can make the correcting mechanism 6 suitable for the correction of battery cells of more specifications.

Exemplarily, the correcting member 61 is screwed/clipped into the mounting position 6511 .

6, in order to realize the horizontal movement of the first power output member 642, the first driving assembly 64 includes a first seat body 641, the first seat body 641 is fixed to the frame 1, and the first power output member 642 is slidably connected to the first seat body 641 in the horizontal direction. In other embodiments, the first power output member 642 can also directly form a sliding pair with the frame 1, and the sliding direction of the first power output member 642 is along the horizontal direction.

In some embodiments, the first drive assembly 64 is a cylinder, the first seat body 641 is a cylinder body of the cylinder, and the first power output member 642 is a piston rod of the cylinder. In other embodiments, the first drive assembly 64 is a linear module, the first seat body 641 is a slide rail of the linear module, and the first power output member 642 is a slide table of the linear module.

6 , each mounting assembly 65 further includes a threaded connector 652 , and each correcting member 61 is locked on a mounting position 6511 on a corresponding mounting seat 651 via the threaded connector 652 .

Illustratively, the threaded connector 652 is a bolt or a screw.

Referring to FIG. 6 , each mounting position 6511 is provided with a mounting hole 65111, and a threaded connector 652 is inserted through the mounting hole 65111 to lock the return member 61 on the mounting position 6511; in the vertical direction, the threaded connector 652 can slide along the mounting hole 65111. In this way, the return member 61 can be moved in the vertical direction when the threaded connector 652 is not locked, and then the return member 61 is locked on the mounting position 6511 by the threaded connector 652, so that the height position of the return member 61 can be adjusted to adapt to the return of battery cells of different specifications.

Preferably, in the horizontal direction, the threaded connector 652 abuts against the hole wall of the mounting hole 65111. This can prevent the return member 61 from being displaced in the horizontal direction, thereby ensuring that the return member 61 can abut against the battery cell without causing excessive pressure on the battery cell and causing damage to the battery cell when the preset displacement of the first power output member 642 remains unchanged.

Preferably, referring to Fig. 6, each mounting position 6511 is provided with a plurality of mounting holes 65111, and each mounting assembly 65 includes a plurality of threaded connectors 652, and each mounting hole 65111 corresponds to at least one threaded connector 652, that is, at least one threaded connector 652 passes through one mounting hole 65111. This can prevent the return member 61 from rotating and causing the distance between the two return members 61 to change, thereby ensuring that the return member 61 can abut against the battery cell without causing excessive pressure on the battery cell to damage the battery cell when the preset displacement of the first power output member 642 remains unchanged.

Preferably, each mounting hole 65111 corresponds to at least two threaded connectors 652, that is, at least two threaded connectors 652 pass through the same mounting hole 65111. This is conducive to firmly locking the return member 61 at the mounting position 6511.

In other embodiments, each mounting position 6511 may be provided with only a mounting hole 65111, but one mounting hole 65111 corresponds to a plurality of threaded connectors 652, that is, the plurality of threaded connectors 652 all pass through the same mounting hole 65111 and simultaneously lock the return member 61 on the mounting position 6511. This can also prevent the return member 61 from rotating and causing the distance between the two return members 61 to change.

Preferably, referring to FIG. 6 , a groove 6512 is provided on the mounting seat 651, and the bottom wall of the groove 6512 forms a mounting position 6511. The groove 6512 has two opposite side walls, which are a first limiting wall 65121 and a second limiting wall. The first limiting wall 65121 and the second limiting wall are both planar and perpendicular to the sliding direction of the first power output member 642. The mounting assembly 65 also includes a connecting column 653, both sides of which are planar and respectively abut against the first limiting wall 65121 and the second limiting wall. The return member 61 is fixed to the connecting column 653, and the threaded connector 652 is passed through the mounting position 6511 and is threadedly connected to the connecting column 653. In this way, tightening the threaded connector 652 can lock the connecting column 653 on the installation position 6511, thereby locking the return member 61 on the installation position 6511, and the abutment relationship between the connecting column 653, the first limiting wall 65121 and the second limiting wall can prevent the return member 61 from shifting in the horizontal direction, thereby ensuring that the return member 61 can abut against the battery cell when the preset displacement of the first power output member 642 remains unchanged and will not cause excessive pressure on the battery cell and cause damage to the battery cell.

Referring to FIG. 5 , the opposite sides of the two correcting members 61 are clamping sides 611, which are planar and parallel to each other. A plurality of first partitions 62 are fixedly arranged at equal intervals along the horizontal direction on each clamping side 611, and a first gap 621 is formed between adjacent first partitions 62 on each correcting member 61, wherein the first gap 621 on one correcting member 61 corresponds to the first gap 621 on the other correcting member 61 and forms a space for accommodating a battery cell. In this way, in the process of correcting the position of the battery cell by the correcting mechanism 6, each battery cell enters the corresponding first gap 621 respectively, and the two first partitions 62 forming the first gap 621 can play a role in limiting the position of the battery cell. In this way, the clamping side 611 and the two adjacent first partitions 62 thereon respectively correct the battery cell from three sides of a battery cell, which is conducive to improving the correction effect of the correcting mechanism 6.

Referring to Fig. 5, the sidewall of the first separator 62 is curved, and the distance between two adjacent first separators 62 decreases first and then increases along the direction perpendicular to the clamping side 611. In this way, the battery cell and the first separator 62 are in point contact or line contact, and the contact area between the battery cell and the first separator 62 is small, which is conducive to preventing the battery cell and the first separator 62 from being damaged by large friction.

Referring to Fig. 5, a guide tooth 63 is fixedly disposed on one side of each first partition 62 away from the clamping side 611, and a second gap 631 exists between two adjacent guide teeth 63 on the same correcting member 61, and the second gap 631 gradually widens in a direction gradually approaching another correcting member 61. In this way, even if the battery cell is offset to a certain extent, it can smoothly enter the first gap 621 through the second gap 631 under the guidance of the guide tooth 63, which is conducive to the correcting mechanism 6 to smoothly correct the position of the battery cell.

Preferably, the gap between two adjacent guide teeth 63 on the same correcting member 61 is in an eight-shaped shape.

Referring to FIG5 , the side wall of the guide teeth 63 is truncated cone or conical. Thus, even if the battery cell is displaced to a certain extent and contacts the guide teeth 63, the battery cell and the guide teeth 63 are only in point contact, and the contact area between the battery cell and the guide teeth 63 is small, which is conducive to preventing the battery cell from being damaged by large friction with the guide teeth 63.

Preferably, referring to FIG. 1 , in some embodiments, the suction cup unit 2 can be raised and lowered. The process of transferring the battery cell from the first boat 400 to the suction cup unit 2 is as follows: the top piece 5 stops after pushing the battery cell to the height position of the correction mechanism 6; then, the two correction members 61 of the correction mechanism 6 approach each other to correct the position of the battery cell, and after the correction of the position of the battery cell is completed, the two correction members 61 move away from each other; then, the suction cup unit 2 descends to gradually approach the battery cell, and after each battery cell lifted by the top piece 5 is located in the corresponding fourth gap 211, each suction cup of the suction cup unit 2 absorbs the corresponding battery cell. The process of transferring the battery cells from the suction cup unit 2 to the second boat 500 is as follows: the suction cup unit 2 is fixed, and the top piece 5 rises to gradually approach the battery cells. After each battery cell adsorbed by the suction cup unit 2 is located in the corresponding third gap 53, each suction cup of the suction cup unit 2 releases the corresponding battery cell; then, the two correcting parts 61 of the correcting mechanism 6 approach each other to correct the position of the battery cell. After the correction of the position of the battery cell is completed, the two correcting parts 61 move away from each other; then, the top piece 5 slowly and steadily descends to allow the battery cell to enter the second boat 500.

For example, referring to FIG. 1 , the cell transport loading device 100 further includes a mechanical arm 8, which has a translation joint, and the movement direction of the translation joint is along the vertical direction. The suction cup unit 2 is fixed at the end of the mechanical arm 8, and the translation joint of the mechanical arm 8 moves up and down to drive the suction cup unit 2 to rise and fall. The base of the mechanical arm 8 can be fixed on the ground, or directly fixed on the frame 1.

In other embodiments, the suction cup unit 2 is fixed. When the battery cell is transferred from the first boat 400 to the suction cup unit 2, the top piece 5 is continuously raised to push the battery cell directly into the suction cup unit 2. In these embodiments, in order to prevent the battery cell from a large positional deviation, the top piece 5 is slowly and steadily raised at a very low speed, and the width of the third gap is only slightly larger than the thickness of the battery cell. For example, the width of the third gap is 0.05 mm larger than the thickness of the battery cell. In these embodiments, when the battery cell is transferred from the suction cup unit 2 to the second boat 500, the top piece 5 is raised to gradually approach the battery cell. After each battery cell adsorbed by the suction cup unit 2 is located in the corresponding third gap 53, each suction cup of the suction cup unit 2 releases the corresponding battery cell; then the top piece 5 is lowered to allow the battery cell to enter the second boat 500. In these embodiments, a correction mechanism 6 may also be provided. Before the battery cell is pushed into the suction cup unit 2 and before the battery cell enters the second boat 500, the correction mechanism 6 may also be used to correct the position of the battery cell.

The second driving assembly 313 is also provided with two boat clamping members 3121, which are arranged one by one in correspondence with the boat clamping members 3121. In this way, by moving the two boat clamping members 3121 simultaneously along the thickness direction of the boat support platform 311, the positions of the two boat clamping members 3121 can be changed, thereby adjusting the clamping position. According to the thickness of the base of the boat to be clamped, the two boat clamping members 3121 are synchronously moved along the thickness direction of the boat supporting platform 311 to the optimal clamping position or near the optimal clamping position, and then the two second driving components 313 drive the two boat clamping members 3121 to move toward each other until the two boat clamping members 3121 abut against the two sides of the boat base, so that the boat can be stably clamped.

Referring to FIG. 10 and FIG. 11 , the second driving assembly 313 further includes a second seat body 3131, the second seat body 3131 is fixedly arranged at the bottom side of the boat support platform 311, and a second power output member 3132 is slidably connected to the second seat body 3131, and the second power output member 3132 slides relative to the second seat body 3131 along the horizontal direction.

In some embodiments, the second drive assembly 313 is a cylinder, the second seat 3131 is a cylinder body of the cylinder, and the second power output member 3132 is a piston rod of the cylinder.

The boat clamping member 3121 is fixed to the third power output member, and two third driving assemblies 314 are provided and are arranged one-to-one with the boat clamping members 3121. In this way, the lifting and lowering of the third power output member can drive the boat clamping member 3121 to move along the thickness direction of the boat support platform 311, thereby adjusting the position of the boat clamping member 3121.

9 to 11, the third driving assembly 314 further includes a third seat body 3141, the third seat body 3141 is fixed to the second power output member 3132, the third power output member is slidably connected to the third seat body 3141, and the third power output member slides relative to the third seat body 3141 along the thickness direction of the boat support platform 311. In this way, the third power output member slides relative to the third seat body 3141, and the boat clamping member 3121 can be driven to move along the thickness direction of the boat support platform 311, thereby adjusting the position of the boat clamping member 3121.

In some embodiments, the third drive assembly 314 is a cylinder, the third seat body 3141 is a cylinder body of the cylinder, and the third power output member is a piston rod of the cylinder. In other embodiments, the third drive assembly 314 is a linear module, the third seat body 3141 is a slide rail of the linear module, and the third power output member is a slide table of the linear module.

In other embodiments, the boat clamp 3121 may also directly form a sliding pair with the second power output member 3132 , and the sliding direction of the sliding pair is along the thickness direction of the boat support platform 311 , which can also enable the boat clamp 3121 to move along the thickness direction of the boat support platform 311 .

In other embodiments, the positions of the second drive component 313 and the third drive component 314 can be exchanged. Specifically, the third seat body 3141 is fixed to the boat supporting platform 311, the third power output member is slidably connected to the third seat body 3141, the second seat body 3131 is fixed to the third power output member, the second power output member 3132 is slidably connected to the second seat body 3131, and the boat clamping member 3121 is fixed to the second power output member 3132.

7 to 11, in order to facilitate the fixing of the third seat body 3141 and the second power output member 3132, the boat clamping mechanism 31 further includes a connecting member 315, the connecting member 315 is fixedly arranged on the second power output member 3132, and the third seat body 3141 is fixedly arranged on the connecting member 315. Two connecting members 315 are provided and are arranged one-to-one with the second power output member 3132. Preferably, the connecting member 315 is a plate-shaped body.

Referring to FIG. 11 , the second driving assembly 313 further includes a guide structure 3133, which includes a guide sleeve 31332 and a guide member 31331. The guide sleeve 31332 is fixed to the bottom side of the boat support platform 311 and is provided with a guide hole that is conformally matched with the guide member 31331. The guide member 31331 is fixed to the third seat body 3141, penetrates the guide hole, and is parallel to the second power output member 3132. In this way, the matching relationship between the guide member 31331 and the guide hole plays a guiding role, which can guide and restrict the second power output member 3132 when it moves horizontally, so as to ensure the accuracy and stability of the horizontal movement of the second power output member 3132.

Referring to Fig. 11, the guide member 31331 is a cylinder, and the guide hole is a circular hole. In other embodiments, the guide member 31331 may also be a columnar body of other shapes, and the guide hole may be a hole of other shapes, for example, the guide member 31331 may be a triangular prism or a square prism, and correspondingly, the guide hole may be a triangular hole or a square hole.

Preferably, the first driving member includes two guide structures 3133, and the two guide structures 3133 are respectively located on both sides of the second power output member 3132.

More preferably, the two guide structures 3133 are symmetrically arranged about the second power output member 3132. This is conducive to enhancing the guiding effect and improving the accuracy and stability of the horizontal movement of the second power output member 3132.

7 to 11 , the boat clamping device 3 further includes a supporting sheet structure 32 , and the supporting sheet structure 32 is used to support the battery cells in the boat during the turning process of the boat clamping device 3 .

7 to 11, the support sheet structure 32 is disposed on the same side of the two boat clamping members 3121. Thus, when the boat clamping device 3 is turned over in a specific direction (clockwise in FIG. 7), the support sheet structure 32 is located below the boat clamped by the boat clamping mechanism 31, thereby supporting the battery cells in the boat and preventing the battery cells from falling out of the boat.

Referring to FIGS. 7 to 11 , the support structure 32 includes two support members 321, which are arranged opposite to each other and are rotatably connected to the two boat clamping members 3121. In this way, the space between the two support members 321 can be used for the top member 5 to pass through, and the two support members 321 are rotated to contact the battery cells in the boat clamped by the two boat clamping members 3121, so as to support the battery cells in the boat. Before the boat is clamped in the boat clamping device 3, or before the boat is taken out of the boat clamping device 3, the two support members 321 can be rotated away from each other to a position where they will not contact the battery cells, so as to prevent the friction between the support members 321 and the battery cells from damaging the battery cells.

Referring to FIGS. 7 and 8 , the support piece 321 includes a first rotating shaft 3212, which is rotatably connected to the boat clamping piece 3121. The support piece structure 32 also includes a fourth driving assembly 322, which includes a fourth seat body 3221, a fourth power output member 3222, and a first transmission member 3223. The fourth seat body 3221 is rotatably connected to the boat clamping piece 3121, and the fourth power output member 3222 is slidably connected to the fourth seat body 3221. The first transmission member 3223 is rotatably connected to the fourth power output member 3222 and fixedly connected to the first rotating shaft 3212. In this way, when the fourth power output member 3222 slides, the fourth seat body 3221 rotates relative to the boat clamping piece 3121, and the first transmission member 3223 rotates relative to the fourth power output member 3222 and drives the first rotating shaft 3212 to rotate, so that the support piece 321 can rotate.

In some embodiments, the fourth seat body 3221 is a cylinder body of a cylinder, and the fourth power output member 3222 is a piston rod of the cylinder. In other embodiments, the fourth seat body 3221 is a slide rail of a linear module, and the fourth power output member 3222 is a slide table of a linear module.

Referring to FIG9 and FIG10 , a positioning member 3111 is provided on the boat support platform 311 , one side of the positioning member 3111 is a positioning side 31111 , the positioning side 31111 is in a plane shape, and the side of each boat clamping member 3121 facing the other boat clamping member 3121 is a boat clamping side 31211 , the boat clamping side 31211 is in a plane shape and perpendicular to the positioning side 31111 . In this way, after placing the boat on the boat support platform 311 , one side of the boat base is close to the positioning side 31111 , and the boat can be positioned. After the boat is positioned, the other two sides of the boat are parallel to the boat clamping side 31211 , and the boat can be clamped and fixed by moving the two boat clamping members 3121 toward each other. Preferably, two positioning members 3111 are provided, and the positioning sides 31111 of the two positioning members 3111 are opposite to each other, so that the two sides of the base of the boat can be respectively close to the positioning sides 31111 of the two positioning members 3111, and the two positioning members 3111 play a limiting role on the boat, which is conducive to the boat clamping mechanism 31 to stably clamp the boat.

8 and 10, the support piece 321 has a planar supporting side 3211, and the support piece 321 can be rotated until the supporting side 3211 is parallel to the positioning side 31111. When the support piece 321 is rotated until the supporting side 3211 is parallel to the positioning side 31111, the supporting side 3211 can contact each battery cell in the boat one by one, thereby supporting each battery cell.

In other embodiments, the supporting sheet structure 32 may also be a plate-shaped structure or a rod-shaped structure fixed to the boat clamp 3121 .

In other embodiments, the supporting structure 32 may be disposed on the boat support platform 311 .

In order to prevent the battery cells from falling out of the boat, the boat is usually in a vertical state. In order to push the battery cells out of the boat, the boat needs to be flipped to a horizontal state. Referring to Figure 12, the battery cell transfer and loading equipment 100 also includes two boat turning mechanisms 7, and the boat turning mechanisms 7 are arranged one by one corresponding to the boat clamping devices 3. The boat turning mechanism 7 has a second rotating shaft 71 that can output rotational motion, and the boat supporting platform 311 of each boat clamping device 3 is fixedly arranged on the second rotating shaft 71 corresponding to the boat turning mechanism 7. In this way, when the second transmission shaft rotates, it drives the boat supporting platform 311 to rotate, thereby driving the boat clamped by the two boat clamping members 3121 to rotate, and then flipping the boat to a horizontal state or a vertical state.

Referring to FIG. 12 , the boat turning mechanism 7 further includes a second transmission member 73 and a fifth driving assembly 72, and the fifth driving assembly 72 includes a fifth seat body 721 and a fifth power output member 722. The fifth seat body 721 is rotatably connected to the switching platform 4, and the fifth power output member 722 is slidably connected to the fifth seat body 721. The second transmission member 73 is rotatably connected to the fifth power output member 722 and fixedly connected to the second rotating shaft 71, and the second rotating shaft 71 is rotatably connected to the switching platform 4. In FIG. 12 , the first boat 400 is in a horizontal state, and the second boat 500 is in a vertical state. Accordingly, the two boat turning mechanisms 7 in FIG. 12 are in different states. By comparing the states of the two boat flipping mechanisms 7 in Figure 12, it can be seen that: when the fifth power output member 722 slides, the fifth seat body 721 rotates relative to the switching table 4, the second transmission member 73 rotates relative to the fifth power output member 722 and drives the second rotating shaft 71 to rotate, thereby driving the boat supporting platform 311 to rotate, and then driving the boat clamped by the two boat clamping members 3121 to rotate, thereby flipping the boat to a horizontal state or a vertical state.

In the embodiment shown in FIG. 12 , the boat support platform 311 is fixed to the second rotating shaft 71 via a centering component.

Preferably, referring to FIG. 12 , the fifth driving assembly 72 is a cylinder, the fifth seat body 721 is a cylinder body, and the fifth power output member 722 is a piston rod. When the piston of the fifth power output member 722 is at the zero point, the second rotating shaft 71 is in the first state; when the piston of the fifth power output member 722 is at the end point, the second rotating shaft 71 is in the second state. The second state of the second rotating shaft 71 is rotated 90° relative to the first state. In other words, in the process of the piston of the fifth power output member 722 moving from the zero point to the end point, the fifth power output member 722 drives the second rotating shaft 71 to rotate 90°. In this way, the fifth driving assembly 72 can just flip the boat clamped by the boat clamping device 3 by 90°.

Referring to FIG. 12 , in the fifth driving assembly 72 on the right, the piston of the fifth power output member 722 is at the zero position. In the fifth driving assembly 72 on the left, the piston of the fifth power output member 722 is at the end position. When the piston of the fifth power output member 722 is at the zero position, the boat clamped by the corresponding boat clamping device 3 is in a vertical state. By comparing the two fifth driving assemblies 72 and the boats clamped by the corresponding boat clamping devices 3, it can be seen that: in the process of the piston of the fifth power output member 722 moving from the zero point to the end point, the boat clamped by the corresponding boat clamping device 3 flips from the vertical state to the horizontal state.

In other embodiments, the fifth driving assembly 72 may also be a linear module, the fifth seat body 721 is a slide rail of the linear module, and the fifth power output component 722 is a slide table of the linear module.

Referring to FIG. 13 , the present invention further provides a battery cell transport and loading system, which includes a placement table 200, a conveying mechanism 300, and the above-mentioned battery cell transport and loading device 100. The placement table 200 is spaced apart from the rack 1 or fixed to the rack 1, and is used to place the above-mentioned first boat 400 and second boat 500. The conveying mechanism 300 is spaced apart from the rack 1 or fixed to the rack 1, and can convey the first boat 400 from one of the placement table 200 and a boat clamping device 3 to the other, and can convey the second boat 500 from one of the placement table 200 and another boat clamping device 3 to the other. Specifically, the transport mechanism 300 transports the first boat 400 carrying the battery cells to a boat clamping device 3, and after the battery cells in the first boat 400 are removed, the empty first boat 400 is transported to the placement table 200 by the boat clamping device 3; the transport mechanism 300 transports the empty second boat 500 to another boat clamping device 3, and after the battery cells are moved into the second boat 500, the second boat 500 carrying the battery cells is transported to the placement table 200 by the boat clamping device 3. Because the battery cell transport and loading system includes the above-mentioned battery cell transport and loading device 100, the battery cell transport and loading system has the technical effects of the above-mentioned battery cell transport and loading device 100. Since the relevant technical effects have been fully described in the foregoing text, they will not be repeated here.

Exemplarily, the placement table 200, the transport mechanism 300 and the cell transfer loading device 100 are fixed on the ground in sequence and at intervals. The transport mechanism 300 can be a robot.

The present invention also provides a battery cell transport and loading method, which is used in the above-mentioned battery cell transport and loading device 100, and the method comprises the following steps:

S100. The top sheet member 5 is located directly below the loading and unloading space, and the first boat 400 carrying the battery cells is clamped in a boat clamping device 3; the first boat 400 is in a horizontal state, and the first boat 400 is located in the loading and unloading space;
