On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

As shown in Figures 1 to 14, an embodiment of the present invention provides a feeding device for a microelectronic device placement machine, including: a supporting base plate 1; and also including: a first feeding portion 2, which is arranged on the supporting base plate 1; a second feeding portion 3, which is arranged on the supporting base plate 1 and cooperates with the first feeding portion 2 to adjust the movement position of the electronic device; a first steering portion 6, which is arranged on the supporting base plate 1 and cooperates with the second feeding portion 3 to adjust the orientation of the electronic device; a grabbing steering portion 8, which is arranged on the supporting base plate 1 and cooperates with the first steering portion 6 to place the electronic device at a specified angle; a conveyor belt 9, which is arranged on the supporting base plate 1 and is connected to the placement machine.

In the embodiment of the present invention, by wrapping the magnetic film 10 on the long electronic device, the use requirements of the patch on the printed circuit board are met, and a magnetic field exists on the electronic device.

By providing the first feeding part 2 and the second feeding part 3, the disorderly electronic devices are neatly arranged in a row and moved to the first turning part 6. By providing the first turning part 6, the positive and negative poles of the electronic devices are in the same direction, so that the electronic devices are neatly arranged before moving to the placement machine. At this time, by providing the grabbing turning part 8, after grabbing each electronic device, the electronic device is placed on the conveyor belt 9 according to the installation angle required by the placement machine, and finally grabbed by the placement machine.

As shown in Figures 3 and 4, the first feeding part 2 includes: a first vibration motor 201, which is arranged on the supporting base plate 1; a vibration disk 202, which is connected to the output end of the first vibration motor 201; a spiral sheet 203, which is arranged in the vibration disk 202; a blocking arc plate 204, one end of which is connected to the inner wall of the vibration disk 202 and cooperates with the spiral sheet 203, so that the electronic device can only pass through the gap between the blocking arc plate 204 and the spiral sheet 203 at one angle; a first guide, which is arranged on the vibration disk 202 and the other end of which is connected to the second feeding part 3 to transport the electronic device to the second feeding part 3.

In the embodiment of the present invention, a large number of electronic devices are placed in the vibration disk 202, and the first vibration motor 201 is started to drive the electronic devices to make a spiral rotation moving outward around the central axis of the vibration disk 202 in the vibration disk 202, so that the electronic devices move upward along the spiral sheet 203. Due to the different widths and heights of the electronic devices, the provided blocking arc plate 204 will push the electronic devices that do not meet the required placement state off the spiral sheet 203, so that the electronic devices whose length and width are in contact with the ground pass through the blocking arc plate 204, and then pass through the first guide member to move to the second feeding part 3;

Among them, the first guide member includes a first limiting plate 205 and a first guiding block 206. The first limiting plate 205 generates linear vibration to drive the electronic device to move forward. The first guiding block 206 limits the position of the first limiting plate 205 so that the electronic device can only move in a direction parallel to its own long side, and the first vibration motor 201 is arranged in the first circular groove 101 opened on the supporting base plate 1.

As shown in Figures 5, 6, 7, 8 and 9, the second feeding part 3 includes: a second slide groove 103, which is opened on the supporting base plate 1; a sliding member, which slides in the second slide groove 103; a reciprocating driving member, which is arranged on the supporting base plate 1 to drive the sliding member to reciprocate; a feeding inclined plate 301, which is arranged on the sliding member; a second limiting plate 302, which is provided with a plurality of groups, and a plurality of groups of the second limiting plates 302 are arranged on the feeding inclined plate 301 to evenly separate the space on the feeding inclined plate 301 to transport the electronic devices to the designated positions in sequence; a second guide block 303, which is arranged on two adjacent second limiting plates 302 to limit the moving trajectory of the electronic devices; a limiting member, which is arranged on the second feeding part 3 to control the opening or closing of the second feeding part 3.

In an embodiment of the present invention, the sliding member is driven to slide by a reciprocating drive member, so that the electronic devices on the first limit plate 205 fall into the space separated by several second limit plates 302 on the feeding inclined plate 301 in sequence, that is, several transport channels; after the electronic devices fall into the last transport channel, the feeding inclined plate 301 will rebound quickly under the action of the reciprocating drive member; the first transport channel on the feeding inclined plate 301 is connected to the last transport channel, so that the next electronic device falls into the first transport channel, completing the complete connection from the first feeding part 2 to the second feeding part 3; finally, after rebounding, the electronic devices on the feeding inclined plate 301 are moved to the first turning part 6 by moving the limit member.

As shown in Figures 5 to 9, the sliding member includes: a second sliding block 501, which slides in the second sliding groove 103; a first supporting side plate 507, which is arranged on the second sliding block 501, and the top end is connected to the feeding inclined plate 301; a second supporting side plate 508, which is arranged on the second sliding block 501, is parallel to the first supporting side plate 507, and the top end is connected to the feeding inclined plate 301; a sliding hole 509, which is opened on the second supporting side plate 508; a second spring telescopic rod 510, one end of which is connected to the first supporting side plate 507; a first abutting inclined plate 511, which slides in the sliding hole 509, and one end is connected to the other end of the second spring telescopic rod 510, and cooperates with the reciprocating drive member to realize the reciprocating sliding of the sliding member.

As shown in Figures 5 to 9, the reciprocating drive member includes: a second fixed block 514, which is arranged on the supporting base plate 1; a hydraulic cylinder 504, which is arranged on the second fixed block 514; a first slide groove 102, which is opened on the supporting base plate 1; a first slider 502, which slides in the first slide groove 102, and one end close to the hydraulic cylinder 504 is connected to the output end of the hydraulic cylinder 504; an abutment block 512, which is arranged on the first slider 502 and cooperates with the first abutment inclined plate 511 to drive the sliding member to slide; a first fixed block 505, which is arranged on the supporting base plate 1; a first spring telescopic rod 506, one end of which is connected to the first fixed block 505, and the other end is connected to the second slider 501; a second abutment inclined plate 513, which is arranged on the supporting base plate 1, and cooperates with the first abutment inclined plate 511 to drive the first abutment inclined plate 511 to disengage from the abutment block 512.

In the embodiment of the present invention, the first slider 502 is driven to slide along the first slide groove 102 by starting the hydraulic cylinder 504. The sliding of the first slider 502 drives the abutment block 512 to slide. The abutment block 512 abuts against the non-inclined end of the first abutment inclined plate 511, driving the first abutment inclined plate 511 to move together, thereby driving the second supporting side plate 508 and the feeding inclined plate 301 to move, thereby driving the second slider 501 to move along the second slide groove 103. At this time, the first spring telescopic rod 506 contracts; when the first abutment inclined plate 511 moves to the second abutment inclined plate 513, at this time, the feeding inclined plate 301 moves to the space separated by the last second limiting plate 302 and borders on the first limiting plate 205; when the two inclined surfaces of the second abutting inclined plate 513 and the first abutting inclined plate 511 are in contact, the second abutting inclined plate 513 will generate pressure, causing the first abutting inclined plate 511 to move inward along the sliding hole 509. At this time, the second spring telescopic rod 510 is squeezed, and at the same time, the first abutting inclined plate 511 is separated from the abutting block 512, so that the first spring telescopic rod 506 rebounds, driving the second slider 501 and the feeding inclined plate 301 The second spring telescopic rod 510 rebounds rapidly and returns to the starting position; at this time, when the abutting block 512 driven by the hydraulic cylinder 504 disengages from the first abutting inclined plate 511, an electrical signal is transmitted to the control center, and the hydraulic cylinder 504 is controlled by the control center to move in the opposite direction, so that the first slider 502 drives the abutting block 512 to slide in the opposite direction along the first slide groove 102. When the abutting block 512 approaches the first abutting inclined plate 511 from the opposite direction, the abutting block 512 is at one end of the first abutting inclined plate 511, thereby squeezing the first abutting inclined plate 511. The first abutment inclined plate 511 compresses the second spring telescopic rod 510. After the abutment block 512 moves to the other end of the first abutment inclined plate 511, the second spring telescopic rod 510 rebounds and the first abutment inclined plate 511 returns to its original state. At this time, the hydraulic cylinder 504 moves to the maximum stroke and starts to move in the opposite direction. The abutment block 512 drives the first abutment inclined plate 511 to slide again, thereby forming a reciprocating motion. During this process, after the electronic device moves to the feeding inclined plate 301, it will move downward along several transport channels and will eventually be stopped by the limit member.

As shown in Figures 5 to 9, the limiting member includes: a connecting ear 405, which is arranged at one end of the second limiting plate 302 away from the first feeding part 2; a third limiting plate 406, which is rotatably connected to the connecting ear 405 through both ends of the shaft to prevent the electronic device from moving to the first turning part 6; a second motor 401, which is arranged on the outermost end of the second limiting plate 302; a driving gear 402, which is connected to the output end of the second motor 401; a driven gear 403, which is connected to one end of the shaft and meshingly connected with the driving gear 402; a speed sensor 404, which is arranged on the outermost end of the second limiting plate 302.

In the embodiment of the present invention, when the first spring rebounds, driving the second slider 501 and the feed inclined plate 301 to rebound rapidly and return to the starting position, the speed sensor 404 detects that the speed exceeds the standard, thereby sending an electrical signal to the control center, and the control center controls the second motor 401 to start, driving the driving gear 402 to rotate, and the driving gear 402 drives the driven gear 403 to rotate, so that the warp axis drives the third limit plate 406 to rotate upward, so that the third limit plate 406 no longer blocks the movement of the electronic device, and the electronic devices in the plurality of transport channels continue to move downward along the feed inclined plate 301 to the first steering portion 6; through the control of the control center, the second motor 401 starts in the reverse direction after a certain period of time, driving the driving gear 402 and the driven gear 403 to reverse, thereby driving the third limit plate 406 to rotate downward, closing the connection between the transport channel and the first steering portion 6, so that the next electronic devices are stuck together at the upper end of the third limit plate 406, which is convenient for moving downward at the same time, so that the first steering portion 6 can turn multiple electronic devices at the same time, thereby improving work efficiency.

As shown in Figure 10, the first steering portion 6 includes: a second placement groove 104, which is opened on the supporting base plate 1; an airbag 601, which is arranged on the second placement groove 104; a first support plate 602, which is arranged on the airbag 601; a rotating block 603, which is arranged on the first support plate 602, and is provided in a plurality of groups, and the plurality of groups of the rotating blocks 603 correspond to the feeding spaces separated on the feeding inclined plate 301; an electromagnet 610, which is arranged on the supporting base plate 1 and is located on one side of the second placement groove 104; a linear vibration plate 604, which is arranged in the second placement groove 104; and a movable hole 605, which is opened on the linear vibration plate 604 and corresponds to the plurality of groups of the rotating blocks 603.

In the embodiment of the present invention, when the electronic device moves onto the linear vibration plate 604, the bottom end of the electronic device just covers the movable hole 605. At this time, the airbag 601 is inflated to drive the first support plate 602 to move upward, thereby driving the rotating block 603 to move upward, so that the rotating block 603 passes through the movable hole 605, and the rotating block 603 is lifted. Since the rotating block 603 and the first support plate 602 can rotate and the friction force is small; at this time, the electromagnet 610 is turned on, and the electromagnet 610 is energized to generate magnetism. Since the long strip electronic device is wrapped with a magnetic film 10, the two ends of the electronic device are magnetic poles at this time; at this time, under the action of the electromagnet 610, the electronic device repels each other at the same level, and one end of the electronic device generates a force to push the rotating block 603 to rotate, so that the rotating block 603 drives the electronic device to rotate, so that the other end of the electronic device is close to the electromagnet 610, and the end just close to the electromagnet 610 is attracted by the electromagnet 610 and will not rotate, and finally the electronic device has the same magnetic field to avoid affecting the placement of the chip placement machine. A support block 607 is provided to support the linear vibration plate 604 .

After the steering is completed, the airbag 601 is contracted to close the electromagnet 610, so that the electronic device is stably placed on the linear vibration plate 604, and the third vibration motor 606 is started to drive the linear vibration plate 604 to vibrate, so that the electronic device moves along the linear vibration plate 604 to the fourth limit plate 608. Finally, several electronic devices are neatly arranged within the range of the first limit block 609 and the fourth limit plate 608, thereby facilitating the grasping of the electronic devices by the steering part 8.

As shown in Figures 11 to 13, the grabbing and steering part 8 includes: a connecting side plate 701, which is arranged on the supporting bottom plate 1; a first driving member, which is arranged on the connecting side plate 701; a suction cup 804, which is connected to the connecting first driving member; and a second driving member, which is arranged on the connecting side plate 701 and connected to the first driving member to drive the suction cup 804 to move up and down.

In the embodiment of the present invention, the first driving member drives the suction cup 804 to move horizontally, and the second driving member drives the suction cup 804 to move vertically, so that the suction cup 804 holds the electronic components and moves upward, thereby moving the arranged electronic components to the next process.

In the embodiment of the present invention, the fourth motor 702 is started to drive the first rotating shaft 703 to rotate, and the first rotating shaft 703 drives the first rotating cam 714 to rotate, so that the first rotating cam 714 squeezes the fourth clamping shaft, so that the L-shaped rotating rod 713 rotates around the fixed shaft 712, and the third clamping shaft 715 on the L-shaped rotating rod 713 drives the second movable plate 716 to slide along the first fixed sleeve 717, thereby driving the third supporting side plate 801, the third movable plate 802, the second fixed sleeve 803 and the suction cup 804 to move horizontally.

As shown in FIGS. 1 to 14, the second driving member includes: a second rotating cam 721, which is sleeved on the first rotating shaft 703; a first rotating rod 704, one end of which is sleeved on the fixed shaft 712; a first clamping shaft 705, which is arranged in the middle of the first rotating rod 704 and is closely connected to the second rotating cam 721; a second clamping shaft 706, which is connected to the other end of the first rotating rod 704; a third fixing block 710, which is arranged on the connecting side plate 701; a first connecting rod 709, which is inserted into the third fixing block 710; a pressing plate 708, which is connected to the top of the first connecting rod 709 end connected; a first movable plate 707, which is arranged on the pressing plate 708 and is sleeved on the second clamping shaft 706; a first connecting plate 711, which is connected to the bottom end of the first connecting rod 709; a first fixed sleeve 717, which is arranged on the first connecting plate 711 and is sleeved on the second movable plate 716; a second connecting rod 718, which is arranged on the first connecting plate 711; a third connecting rod 719, one end of which is rotatably connected to the second connecting rod 718; a fourth connecting rod 720, one end of which is connected to the other end of the third connecting rod 719, and the other end is connected to the upper end of the suction cup 804.

In the embodiment of the present invention, when the fourth motor 702 is started to drive the first rotating shaft 703 to rotate, the first rotating shaft 703 will also drive the second rotating cam 721 to rotate. The rotation of the second rotating cam 721 will drive the first clamping shaft 705 to move up and down, thereby driving the first rotating rod 704 to rotate around the fixed shaft 712, thereby driving the second clamping shaft 706 on the first rotating rod 704 to move up and down, and the second clamping shaft 706 drives the first movable plate 707 to move up and down. The first movable plate 707 drives the first connecting plate 711 to move up and down through the first connecting rod 709, and the first connecting rod 709 drives the second movable plate 716 and the second movable plate 717 to move up and down. The connecting rod 718, the third connecting rod 719, the fourth connecting rod 720, the third supporting side plate 801, the third movable plate 802 and the second fixed sleeve 803 move downward, thereby driving the suction cup 804 to move downward, thereby grabbing the electronic device; when the first connecting rod 709 drives the second movable plate 716 to move downward through the first fixed sleeve 717, the other end of the second movable plate 716 is sleeved on the third clamping shaft 715, that is, a vertically placed rectangular groove is opened at the other end of the second movable plate 716, and when the second movable plate 716 moves downward, the third clamping shaft 715 slides upward in the opened rectangular groove to prevent the structure from getting stuck.

When the first driving member moves laterally, the second movable plate 716 moves along the first fixed sleeve 717, which will drive the third connecting rod 719 to rotate around one end of the second connecting rod 718. At the same time, the other end of the third connecting rod 719 drives the fourth connecting rod 720 to rotate around the second fixed sleeve 803. The end of the fourth connecting rod 720 away from the third connecting rod 719 is connected to the suction cup 804, so that when the fourth connecting rod 720 rotates around the second fixed sleeve 803, it will drive the suction cup 804 to rotate, thereby changing the direction of the suction cup 804 and finally changing the placement direction of the grasped electronic device; the rotation angle of the suction cup 804 can be changed by changing the length of the third connecting rod 719 and the fourth connecting rod 720.

The above movement requirement is achieved by designing the first cam to be in a "convex-concave" state and the second cam to be in a "convex-concave-convex" state.

The overall movement process of the grabbing and steering part 8 is as follows: when the electronic device moves to one side of the first limit block 609, the first rotating shaft 703 is driven to rotate by starting the fourth motor 702, and the first rotating shaft 703 drives the first rotating cam 714 to rotate, so that the first rotating cam 714 squeezes the fourth clamping shaft to move upward, so that the L-shaped rotating rod 713 rotates around the fixed shaft 712, and the third clamping shaft 715 on the L-shaped rotating rod 713 drives the second movable plate 716 to slide along the first fixed sleeve 717, thereby driving the third supporting side plate 801, the third movable plate 802, the second fixed sleeve 803 and the suction cup 804 to move horizontally to the electronic device that is in contact with the first limit block 609. At the top of the device, at this time, the first rotating shaft 703 will also drive the second rotating cam 721 to rotate, and the rotation of the second rotating cam 721 will drive the first clamping shaft 705 to move downward, thereby driving the first rotating rod 704 to rotate around the fixed shaft 712, thereby driving the second clamping shaft 706 on the first rotating rod 704 to move downward, and the second clamping shaft 706 drives the first movable plate 707 to move downward, and the first movable plate 707 drives the first connecting plate 711 to move downward through the first connecting rod 709, and the first connecting rod 709 drives the second movable plate 716, the second connecting rod 718, the third connecting rod 719, the fourth connecting rod 720, the third supporting side plate 801, and the third movable plate 802 and the second fixed sleeve 803 move downward, thereby driving the suction cup 804 to move downward, so that the suction cup 804 absorbs the electronic device. At this time, the second rotating cam 721 continues to rotate and drives the first clamping shaft 705 to move upward, thereby driving the suction cup 804 to move upward. At this time, the first rotating cam 714 continues to rotate, driving the fourth clamping shaft to move downward, so that the L-shaped rotating rod 713 rotates around the fixed shaft 712, and the third clamping shaft 715 on the L-shaped rotating rod 713 drives the second movable plate 716 to slide along the first fixed sleeve 717, thereby driving the third supporting side plate 801, the third movable plate 802, the second fixed sleeve 803 and the suction cup 804 to do reverse lateral movement. The suction cup 804 moves to the top of the conveyor belt 9. During this process, the second movable plate 716 moves along the first fixed sleeve 717, which drives the third connecting rod 719 to rotate around one end of the second connecting rod 718. At the same time, the other end of the third connecting rod 719 drives the fourth connecting rod 720 to rotate around the second fixed sleeve 803. The end of the fourth connecting rod 720 away from the third connecting rod 719 is connected to the suction cup 804. When the fourth connecting rod 720 rotates around the second fixed sleeve 803, the suction cup 804 is driven to rotate, thereby changing the direction of the suction cup 804, and finally changing the placement direction of the captured electronic device, so that the electronic device is placed at the angle required by the placement machine.

At this time, the first rotating shaft 703 will also drive the second rotating cam 721 to rotate. The rotation of the second rotating cam 721 will drive the first clamping shaft 705 to move downward, thereby driving the first rotating rod 704 to rotate around the fixed shaft 712, thereby driving the second clamping shaft 706 on the first rotating rod 704 to move downward, and the second clamping shaft 706 drives the first movable plate 707 to move downward. The first movable plate 707 drives the first connecting plate 711 to move downward through the first connecting rod 709. The first connecting rod 709 drives the second movable plate 716, the second connecting rod 718, the third connecting rod 719, the fourth connecting rod 720, the third supporting side plate 801, the third movable plate 802 and the second fixed sleeve 803 to move downward, thereby driving the suction cup 804 to move downward, so that the electronic device is placed on the conveyor belt 9, and then the suction of the suction cup 804 is closed, so that the electronic device is placed on the conveyor belt 9, and finally the electronic device is sent to the placement machine in a standard placement orientation.

The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
