Description

Technical Field

[0001] This utility model relates to the field of chip mounters, specifically to a bulk chip mounter. Background Technology

[0002] In the field of electronic component placement technology, the placement of electronic components is a highly technical and complex process. Pick-and-place machines are a primary piece of equipment for this task. During operation, a computer-aided control system and a corresponding positioning system accurately position the placement head. The nozzle on the placement head automatically picks up the components from the automatic feeder, and then the transmission system drives the placement head to accurately place the electronic components onto the corresponding positions on the target circuit board, completing one automatic placement cycle. However, the automatic feeder typically uses a vibratory feeder, and the placement head can only pick up one component at a time, resulting in low placement efficiency. Utility Model Content

The feeding assembly includes a vibratory feeder and a rotary feeding mechanism, wherein the rotary feeding mechanism is used to transfer the product supplied by the vibratory feeder to the trough of the conveying block located at the feeding position; The bonding head assembly includes a first turntable, a first suction head, a first rotary drive, and a first Z-axis pressing member. Multiple first suction heads are arranged in a ring on the first turntable. Each first suction head includes a mounting block, a suction rod slidably connected to the mounting block in a vertical direction, a suction block connected to the bottom of the suction rod, and multiple suction nozzles connected to the suction block. An elastic member is provided between the suction block and the mounting block.

The first Z-axis pressing member drives the suction rod downward at the material picking position and the patching position. The elastic member provides an elastic force to drive the suction rod upward. As a further improvement to the above technical solution, the linear motor stator includes a first linear motor stator and a second linear motor stator arranged in parallel. A moving platform is provided at both ends of each linear motor stator. Each moving platform includes a lateral moving module and a third linear motor stator. The lateral moving module is used to drive the third linear motor stator to move laterally to dock with either the first or second linear motor stator. When the third linear motor stator docks with the first linear motor stator, the linear motor actuator can move between the first and third linear motor stators. When the third linear motor stator docks with the second linear motor stator, the linear motor actuator can move between the second and third linear motor stators.

The suction head of the first suction head integrates multiple suction nozzles, which can simultaneously pick up multiple products in the material trough. With the help of the first Z-axis pressing component, multiple products can be picked up and placed synchronously. Compared with the existing technology of vibratory feeder feeding material once and placement head picking up material once, the placement efficiency is greatly improved. Attached Figure Description

The various technical features in this utility model can be combined interactively without contradicting each other.

[0018] Reference Figures 1-3 This utility model provides a bulk material placement machine, including a machine base 100, a placement worktable 300 mounted on the machine base 100, a ring motor assembly 700, a feeding assembly, a bonding assembly 400, a shaping assembly 800, and a vision assembly. The feeding assembly includes a vibratory feeder 500 and a rotary feeding mechanism 600. The rotary feeding mechanism 600 is used to transfer the products supplied by the vibratory feeder to the ring motor assembly 700. The bonding assembly 400 transfers the products on the ring motor assembly 700 to the shaping assembly 800 for shaping, and then transfers them to the placement worktable 300 for placement. The vision assembly detects whether the products meet the placement standards. Defective products (products that do not meet the standards) are directly transferred to the waste disposal area for disposal.

[0019] In this embodiment, refer to Figure 2 The placement worktable 300 includes a stage 310, an X-axis transverse module 320, and a Y-axis transverse module 330. The stage 310 is connected to the drive end of the X-axis transverse module 320, and the X-axis transverse module 320 is connected to the drive end of the Y-axis transverse module 330. Both the X-axis transverse module 320 and the Y-axis transverse module 330 use linear motors, or other linear modules may be used. The stage 310 is used to place the circuit board to be placed. The X-axis transverse module 320 and the Y-axis transverse module 330 respectively drive the stage 310 to move along the X and Y axes, thereby adjusting the placement position.

[0020] In this embodiment, refer to Figure 4 and Figure 5The ring motor assembly 700 is mounted on the base plate 710 and includes a linear motor stator and multiple linear motor movers 780 that move along a circular trajectory on the linear motor stator. The linear motor movers 780 are connected to a material conveying block 790, and the material conveying block 790 is provided with multiple material troughs 791. The linear motor movers 780 are used to drive the material conveying block 790 to move cyclically between the feeding position and the picking position.

[0021] Specifically, the linear motor stator includes a first linear motor stator 720 and a second linear motor stator 730 arranged in parallel. The first linear motor stator 720 and the second linear motor stator 730 are mounted on a base plate 710. A moving platform is provided at both ends of the linear motor stator. One of the moving platforms includes a lateral moving module A750 and a third linear motor stator A740, and the other moving platform includes a lateral moving module B770 and a third linear motor stator B760. The lateral moving module A750 is used to drive the third linear motor stator A740 to move laterally along the X-axis to dock with the first linear motor stator 720 or the second linear motor stator 730. The lateral moving module B770 is used to drive the third linear motor stator B760 to move laterally along the X-axis to dock with the first linear motor stator 720 or the second linear motor stator 730.

[0022] Lateral movement modules A750 and B770 also use linear motors. The third linear motor stator A740 and the third linear motor stator B760 are fixedly connected to the movers of lateral movement modules A750 and B770, respectively.

[0023] The linear motor mover 780 drives the conveying block 790 to cyclically move between the loading position and the unloading position as follows: At the loading position, the linear motor mover 780 moves from the second linear motor stator 730 to the third linear motor stator A740. Simultaneously, the lateral movement module A750 drives the third linear motor stator A740 to move laterally and dock with the second linear motor stator 730. The linear motor mover 780 can move from the second linear motor stator 730 to the third linear motor stator A740. Then, the lateral movement module A750 drives the third linear motor stator A740 to move laterally and dock with the first linear motor stator 720. The linear motor mover 780 can move from the third linear motor stator A740 to the first linear motor stator 720, thus moving to the unloading position on the first linear motor stator 720 to await the removal of the product by the assembly 400. After the product is removed, the empty space is cleared. The conveying block 790 moves towards the third linear motor stator B760 along with the linear motor mover 780. The lateral movement module B770 drives the third linear motor stator B760 to move laterally and dock with the first linear motor stator 720. The linear motor mover 780 can move from the first linear motor stator 720 to the third linear motor stator B760. Then, the lateral movement module B770 drives the third linear motor stator B760 to move laterally and dock with the second linear motor stator 730. The linear motor mover 780 can move from the third linear motor stator B760 to the second linear motor stator 730, thereby moving to the loading position on the second linear motor stator 730, so that the rotating loading mechanism 600 can transfer the product supplied by the vibratory feeder to the material trough 791. By repeating the above actions by multiple linear motor movers 780, loading can be performed continuously, improving loading efficiency.

[0024] In this embodiment, refer to Figure 6 and Figure 7 The bonding head assembly 400 includes a first turntable 420, a first suction head 430, a first rotary drive component, and a first Z-axis pressing component. A plurality of first suction heads 430 are arranged in a ring on the first turntable 420. The first rotary drive component includes a first rotary motor 410, which is mounted on a first bracket 200 fixed on the machine base 100. The first turntable 420 is mounted on the output end of the first rotary motor 410. When the first rotary motor 410 drives the first turntable 420 to rotate, it drives the first suction head 430 to move cyclically along a ring track. The first suction head 430 passes through the material picking position, the shaping position, the detection position, the bonding position, and the discard position.

[0025] Specifically, refer to Figure 8 and Figure 9The first suction head 430 includes a first mounting block 431, a first suction rod 432 slidably connected to the first mounting block 431 in a vertical direction, a suction block 433 connected to the bottom of the first suction rod 432, and a plurality of first suction nozzles 434 connected to the suction block 433. The first mounting block 431 is provided with a first mounting hole and a second mounting hole. The first suction rod 432 passes through the first mounting hole. The first suction rod 432 is provided with a first fixing block 435. The first fixing block 435 is provided with a first guide rod 436. The first guide rod 436 is slidably connected to the second mounting hole through a first linear bearing 439. A first elastic element is provided between the suction nozzle block 433 and the first mounting block 431. The first elastic element includes a first spring 438, which is sleeved on the first suction nozzle rod 432. A first limiting washer 4310 is fixedly connected to the bottom of the first mounting hole on the first mounting block 431. The bottom of the first spring 438 is connected to the first limiting washer 4310. A first connector 437 is provided at the top of the first suction nozzle rod 432. The first suction nozzle rod 432 is connected to an external negative pressure device through the first connector 437 (the pipeline of the first connector 437 is connected to the external negative pressure device through an air slip ring). The first connector 437 abuts against the top of the first spring 438 when the first suction nozzle rod 432 is downward.

[0026] Furthermore, the first Z-axis pressing component includes a Z-axis motor 440 disposed at the patching position and the material picking position. The Z-axis motor 440 is a voice coil motor. The Z-axis pressing component can also be a linear module such as a linear motor, servo motor, cylinder, or electric cylinder. The Z-axis motor 440 is mounted on the first bracket 200, and the moving part of the Z-axis motor 440 is vertically arranged downwards. The material handling action is as follows: the mover of the Z-axis motor 440 located at the material handling position extends downward and abuts against the top of the first suction nozzle rod 432, then pushes the first suction nozzle rod 432 downward. The first connector 437 abuts against the top of the first spring 438 when the first suction nozzle rod 432 moves downward, thereby compressing the first spring 438. The first suction nozzle 434 moves into the material trough 791 and sucks up the product under negative pressure. Then, the mover of the Z-axis motor 440 retracts, and the restoring force of the first spring 438 pushes the first connector 437 upward, causing the first suction nozzle 434 to leave the material trough 791. The first turntable 420 can then drive the first suction nozzle 434 to rotate to the next station. The placement action is the same as the material handling action, except that after the first suction nozzle 434 moves downward and places the product on the corresponding position on the circuit board, the first suction nozzle 434 breaks the vacuum and releases the product.

[0027] In this embodiment, refer to Figure 2 and Figure 3The feeding components include at least two, and the two feeding components can simultaneously feed the material troughs 791 on the two material conveying blocks 790, thereby further improving the feeding efficiency.

[0028] Specifically, refer to Figure 10 The rotary feeding mechanism 600 includes a second rotary drive component, a second Z-axis pressing component, a second turntable 620, and a second suction head 630. A plurality of second suction heads 630 are arranged in a ring on the second turntable 620. The second rotary drive component includes a second rotary motor 610, which is mounted on a second bracket 640 fixed on the machine base 100. The second turntable 620 is mounted on the output end of the second rotary motor 610. When the second rotary motor 610 drives the second turntable 620 to rotate, it drives the second suction head 630 to move cyclically along a ring track. The second suction head 630 passes through the feeding position (the discharge port of the vibrating plate 500) and the feeding position.

[0029] Specifically, refer to Figure 11 The second suction head 630 includes a second elastic element, a second mounting block 631, a second suction rod 632 slidably connected to the second mounting block 631 in a vertical direction, and a second suction nozzle 633 connected to the bottom of the second suction rod 632. The second mounting block 631 is provided with a second mounting hole and a third mounting hole. The second suction rod 632 passes through the third mounting hole. The second suction rod 632 is provided with a second fixing block 634. The second fixing block 634 is provided with a second guide rod 635. The second guide rod 635 is slidably connected to the fourth mounting hole through a second linear bearing. The second elastic element includes a second spring 636, which is sleeved on the second suction rod 632. A second limiting washer 638 is fixedly connected to the bottom of the second mounting hole on the second mounting block 631. The bottom of the second spring 636 is connected to the second limiting washer 638. A second connector 637 is provided on the top of the second suction rod 632. The second suction rod 632 is connected to an external negative pressure device through the second connector 637 (the pipeline of the second connector 637 is connected to the external negative pressure device through an air slip ring). The second connector 637 abuts against the top of the second spring 636 when the second suction rod 632 is downward.

[0030] Furthermore, the second Z-axis pressing component includes a Z-axis module 650 (the Z-axis module 650 can be a cylinder, or a linear module composed of a transmission structure such as a motor + lead screw) disposed at the patching position and the picking position. The Z-axis module 650 is mounted on the second bracket 640, and when the drive end of the Z-axis module 650 moves downward, it can abut against the top of the second suction nozzle rod 632. Picking action: The Z-axis module 650 located at the feeding position drives the second suction nozzle rod 632 to move downward. When the second suction nozzle rod 632 moves downward, the second connector 637 abuts against the top of the second spring 636, thereby compressing the second spring 636. The second suction nozzle 633 moves to the outlet of the vibratory feeder 500 to suck up the product under negative pressure. Then the Z-axis module 650 resets, and the restoring force of the second spring 636 drives the second connector 637 to move upward, so that the second suction nozzle 633... After leaving the discharge port of the vibratory feeder 500, the second turntable 620 can drive the second suction nozzle 633 to rotate to the loading position. Then, the Z-axis module 650 located at the loading position drives the second suction nozzle rod 632 to move downward. After the product on the second suction nozzle 633 moves downward into the material trough 791, the second suction nozzle 633 breaks the vacuum and releases the product. The Z-axis module 650 returns to its original position, and the restoring force of the second spring 636 drives the second connector 637 to move upward, causing the second suction nozzle 633 to leave the material trough 791. By repeating the above actions, the product can be continuously loaded.

[0031] In this embodiment, refer to Figure 2 and Figure 3 The vision component includes a downward-looking camera 910 and a positioning camera 920. The downward-looking camera 910 is located at the detection position between the shaping position and the placement position, and is used for the detection of the shaped product. The bulk material placement machine also includes an open waste container. The waste container is a waste pipe 1000, which is located at the discard position between the placement position and the picking position. When the downward-looking camera 910 detects a defective product, the first turntable 420 drives the first suction head 430 to move to the discard position. The first suction head 430 breaks the vacuum and puts the defective product into the waste pipe 1000 below.

[0032] The positioning camera 920 is located above the patch placement position and is used to locate the patch placement position on the product to ensure the accuracy of the patch placement.
