The present application provides a take-off mechanism, referring to fig. 1, comprising a main frame 10, a guide frame 20, a first drive module, a second drive module 30, and at least one symmetrically disposed gripping portion 40.

The main frame 10 is the backbone and support structure of the entire take off mechanism, providing a mounting and moving platform for other components. Typically made of steel or other high strength metallic material, ensures sufficient rigidity and strength to support the weight of the mechanism and withstand the various stresses during movement. The design of the main frame 10 requires consideration of the overall size, weight distribution, stress analysis, etc. of the mechanism to ensure the stability and safety of the mechanism. The frame is usually optimally designed by adopting methods such as finite element analysis, so that the strength-weight ratio is improved, and the stress concentration is reduced. The main frame 10 may be welded by steel plates or section steel, or cast integrally by casting.

The guide frame 20 is a mechanism for guiding and supporting the movement of the gripping portions 40, which is fixed to the main frame 10, and the guide frame 20 includes branching beams 210 in one-to-one correspondence with the respective gripping portions 40, each gripping portion 40 being movable only under the guidance of the corresponding branching beam 210. The direction in which the branching beams 210 are guided is toward the center of the guide frame 20 and away from the center of the guide frame 20, respectively. The workpiece to be clamped is placed below the center of the guide frame 20, and each clamping part 40 is close to the center of the guide frame 20, so that the workpiece to be clamped can be clamped. After the workpiece is conveyed to the target position, each gripping portion 40 is moved away from the center near the guide frame 20, and the gripped workpiece can be lowered. In the present application, the gripping parts 40 are arranged in pairs, each pair of gripping parts 40 is located on two branch beams 210 in the same straight line, and the two gripping parts 40 in the same pair can move in opposite directions or in opposite directions on the two branch beams 210 in the same straight line. When moving in opposite directions, the two clamping portions 40 gradually approach two symmetrical sides of the workpiece, and clamp the two symmetrical sides of the workpiece, and the symmetrical clamping portions 40 provide two symmetrical clamping points. The clamping force can be better dispersed and transferred by increasing the number of the clamping points, the problem of force concentration and workpiece inclination possibly caused by single-point clamping is avoided, and the stability of the workpiece in the direction of the straight line where the two clamping points are located is ensured. In order to ensure the stability of the workpiece, a plurality of pairs of gripping portions 40 may be provided to ensure the stability of the workpiece in each direction.

The movement of the gripping portion 40 on the guide frame 20 can enable the gripping portion 40 to flexibly approach and separate from workpieces of different area sizes, and for performing gripping operation, each gripping portion 40 in this embodiment is provided with a fixed jaw 410 and a movable press block 420. The fixed jaw 410 is the main body of the whole clamping part 40, the movable pressing block 420 is movably connected with the fixed jaw 410, and a variable opening is formed between the movable pressing block 420 and the fixed clamp, and the opening is used for clamping a workpiece. Because the size of the opening can be adjusted, if the movable pressing block 420 is contacted with the workpiece when the opening is reduced, the workpiece can be clamped by continuing moderate movement, so that the workpiece can be clamped stably. And the size of the opening is adjustable, so that the workpiece can be flexibly applicable to workpieces with different thicknesses.

The mechanism can be controlled in two stages when clamping a workpiece. The first stage is to control the gripping portion 40 to move toward each other on the branching beam 210 so that the gripping portion 40 approaches the workpiece. After the gripping portion 40 is in place, it is necessary to control the opening to shrink so that the fixed jaw 410 and the movable platen grip the workpiece. The mechanism can also be controlled in two stages when the workpiece is put down. The opening is controlled to be widened in a first stage so that the fixed jaw 410 and the movable platen loosen the workpiece. The gripping portion 40 is controlled to move back and forth on the branching beam 210 in the second stage so that the gripping portion 40 is away from the workpiece to place the workpiece at the target position.

In the process of clamping and putting down the workpiece, if the opening control actions are not synchronous, the battery piece can be inclined to collide. Therefore, all movable briquettes 420 in the present application need to be driven synchronously, specifically, the power source for each movable briquettes 420 to move relative to the fixed clamping jaw 410 is the first driving module. In other words, the first driving module simultaneously controls all the movable briquettes 420 to move together so that all the openings are simultaneously enlarged or contracted.

Similarly, in addition to the adjustment of the opening size during the process of clamping and dropping the workpiece, the clamping portion 40 needs to move on the branching beams 210, and if the movement of each branching beam 210 is not synchronous, the battery piece may be inclined and collide. Therefore, the movement of all the fixed clamping jaws 410 on the branching beam 210 needs to be synchronized in the present application, specifically, each fixed clamping jaw 410 is connected with the second driving module 30, and the power source for the movement of each fixed clamping jaw 410 on the branching beam 210 is the second driving module 30. In other words, the second drive module 30 simultaneously controls all of the stationary jaws 410 to move together such that all of the openings move synchronously toward each other or away from each other.

Based on the reclaimer mechanism in this embodiment, the mechanism comprises a main frame 10, a guide frame 20, a first drive module, a second drive module 30 and at least one symmetrically arranged gripping portion 40. The two symmetrical edges of the workpiece are respectively clamped by the clamping parts 40 which are symmetrically arranged in pairs, so that the number of clamping points is increased, the clamping force is better dispersed and transmitted, and the clamping stability is improved. The movement of all movable pressing blocks 420 in the mechanism is synchronously controlled by the first driving module, the movement of all fixed clamping jaws 410 on the branching beam 210 is synchronously controlled by the second driving module 30, the consistency of opening and closing and movement of each clamping part 40 is ensured, the problem of workpiece inclination and collision caused by asynchronous movement is avoided, and therefore workpieces can be safely and reliably synchronously placed on a feeding disc, and further, the subsequent packing flow is executed. The mechanism can well replace a manual material taking link, and the production efficiency and quality of the battery piece are greatly improved.

In one embodiment, referring to fig. 1, the first driving module includes an air source and air cylinders 50 corresponding to each movable pressing block 420, the air source is used for providing driving air for each air cylinder 50, the air cylinders 50 are fixed on the corresponding fixed clamping jaws 410, and piston rods of the air cylinders 50 are connected with the corresponding movable pressing blocks 420 and used for driving the movable pressing blocks 420 to move so as to change the opening size.

It will be appreciated that cylinder 50 is an actuator that uses compressed gas to perform work. The cylinder 50 operates on the principle that the piston is pushed to reciprocate linearly by the pressure of the compressed gas. When compressed gas is introduced into one end of the cylinder 50, the piston rod moves along the axis of the cylinder 50 due to the pressure, whereas when the compressed gas is discharged, the piston rod returns to the original position under the action of a spring or load. In the application, the movable pressing block moves up and down to be far away from and close to the claw tip part of the fixed clamping jaw, and the cylinder is also arranged in the vertical direction when in arrangement, so that the piston rod can push the movable pressing block to move up and down to change the size of the opening. The air source may be a compressor, and the air source may be controlled to simultaneously intake or simultaneously exhaust air to each cylinder 50, so as to realize synchronous control of all movable briquettes. The stroke and thrust of the cylinder 50 can be controlled by adjusting parameters such as air pressure, piston diameter and the like. The cylinder is adopted as a power source, so that the cylinder has large thrust and quick response, is suitable for driving the movable pressing block 420, which is a part with a certain load, and ensures the stable clamping of workpieces.

In one embodiment, the second drive module 30 includes a power unit 310 and a transmission unit 320, the power unit 310 being connected to each stationary jaw 410 by the transmission unit 320. It is understood that the power unit 310 provides a power output component, such as a motor, etc. The transmission unit 320 is a mechanism that transmits and converts power into a desired movement form such that the power provided by the power unit 310 can reciprocate the fixed jaw 410 in a straight line on the branching beam 210.

In one embodiment, the power unit 310 is a motor, and the transmission unit 320 includes a rotating frame 3210 and connecting rods 3220 corresponding to the gripping portions 40 one by one. The rotating frame 3210 includes transmission arms 3211 corresponding to the clamping parts 40 one by one, and the center of the rotating frame 3210 is sleeved on the rotating shaft of the motor, so that the rotating frame 3210 can rotate along with the rotation of the rotating shaft of the motor. Each driving arm 3211 on the rotating frame 3210 is connected with the corresponding fixed clamping jaw 410 through a connecting rod 3220, and each group of driving arms 3211 and connecting rods 3220 are equivalent to a crank connecting rod. As shown in fig. 1, when the fixed jaw 410 is far from the center of the rotating frame 3210, the rotating frame 3210 rotates in a first direction, each driving arm 3211 pulls the corresponding link 3220, and the link 3220 applies a force to the corresponding fixed jaw 410, which has a component force directed toward the center of the rotating frame 3210, and all the fixed jaws 410 move toward the center of the rotating frame 3210 under the guiding action of the corresponding branching beam 210. When the fixed jaw 410 approaches the center of the turret 3210, the turret 3210 rotates in a second opposite direction, and each of the driving arms 3211 pushes the corresponding link 3220, and the link 3220 exerts a force on the corresponding fixed jaw 410, which force has a component of force away from the center of the turret 3210, and all the fixed jaws 410 move away from the center of the turret 3210 under the guiding action of the corresponding branching beam 210.

In one embodiment, the branching beams 210 are provided with slide rails 220, and the fixing claws 410 are slidably connected to the corresponding branching beams 210 through the slide rails 220. Slide rail 220 is a mechanism for providing a linear sliding motion guide. A sliding block 411 adapted to the slide rail 220 may be disposed on the fixed clamping jaw 410, so that the sliding block 411 may drive the whole clamping portion 40 to reciprocate linearly on the branching beam 210 under the guidance of the guide rail. The straight line of the sliding rail 220 should pass through the center of the rotating frame 3210, so that the gripping portion 40 can move toward the center of the rotating frame 3210 or away from the center of the rotating frame 3210 under the guidance of the sliding rail 220.

In one embodiment, a bumper pad 430 is provided at the location of contact of the compact with the workpiece. The cushion pad 430 is a soft material layer for buffering and damping, and is disposed at a contact position between the movable pressing block 420 and the workpiece, so as to prevent the workpiece from being damaged by excessive impact force. When the movable pressing block 420 clamps the workpiece, the workpiece is weaker because the hardness of the movable pressing block 420 is high, and if the workpiece is directly contacted with the movable pressing block 420, the workpiece may be damaged or destroyed. The buffer cushion 430 can uniformly transmit clamping force, so that local damage caused by stress concentration is prevented, and safety and completeness of a workpiece are ensured.

In one embodiment, the cushion 430 is made of a material including one of silicone, rubber, sponge, or foam. The materials can deform to a certain extent during compression, so that the effects of buffering and damping are achieved. Meanwhile, the materials have certain recovery capacity and can be gradually recovered after unloading. However, different materials have differences in hardness, wear resistance, recovery rate, working temperature range and the like, and are required to be reasonably selected according to specific use conditions. In general, the soft material is very suitable for being applied to the buffer pad 430 at the contact part of the movable pressing block 420 and the workpiece by virtue of the good buffering and energy absorbing performance, so that the workpiece is effectively prevented from being damaged, and the clamping reliability is ensured.

In one embodiment, the gripping portions 40 are two pairs, and the gripping portions 40 of the two pairs are arranged in a cross shape. That is, in this embodiment, there are four gripping portions 40 in total, and the gripping portions 40 of the two branching beams 210 located on the same straight line are symmetrically arranged gripping portions 40, and the pair of gripping portions 40 can move in opposite directions or in opposite directions on the corresponding straight line. Thus, the directions of movement of the two pairs of gripping portions 40 are perpendicular to each other, forming a cross shape. The structure is particularly suitable for workpieces of various shapes, particularly rectangular workpieces such as stacked battery plates. This may also be because the rectangular workpiece includes two sets of sides parallel to each other, each pair of gripping portions 40 can stably grip one set of sides parallel to each other of the workpiece, and both pairs of gripping portions 40 can stably grip both sets of sides, so that the entire workpiece has extremely high gripping stability. Further, in the structure in which the two pairs of pinching portions 40 are provided, the guide frame 20, the bogie and the main frame 10 may all be provided in a cross shape.

In one embodiment, the contact surfaces of the press block and the fixed jaw 410 and the workpiece are planes parallel to each other. This design takes into account that the upper and lower surfaces of the battery plate are planar, and if the contact surfaces of the press block and the fixing jaw 410 and the battery plate are not parallel, individual contact points occur, so that stress concentration occurs and the battery plate is damaged. The contact surfaces of the pressing block and the fixing jaw 410 are designed to be planes parallel to each other, so that the clamping portion 40 can be contacted with the upper and lower surfaces of the workpiece respectively with the maximum area, thereby improving the reliability and uniformity of clamping.

Finally, it is further noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
