Then, workers manually take the PCBA board out of the incoming material tray, flip it over, and put it into the material box, so that the back of the PCBA board in the material box is against the inner bottom surface of the material box. However, manual packing is labor-intensive and not conducive to saving labor. Summary of the Invention

[0016] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0017] like Figure 1-6 As shown, a PCBA board packing mechanism includes a frame 1, an XYZ three-axis drive unit 2 fixedly connected to the frame 1, a rotary drive unit 3 fixedly connected to the lifting end of the XYZ three-axis drive unit 2, a gripping plate assembly 4 fixedly connected to the output end of the rotary drive unit 3, a lifting drive unit 5 fixedly connected to the frame 1, a flipping drive unit 6 fixedly connected to the output end of the lifting drive unit 6, and a suction cup assembly 7 fixedly connected to the output end of the flipping drive unit 6. The lifting drive unit 5, the flipping drive unit 6, and the suction cup assembly 7 work together to pick up the PCBA board 8 from the incoming tray 9 and flip it over. The XYZ three-axis drive unit 2, the rotary drive unit 3, and the gripping plate assembly 4 work together to grip the PCBA board 8 from the suction cup assembly 7 and transfer it.

[0018] When this packing mechanism is used in conjunction with an existing PCBA depaneling machine, the existing PCBA depaneling machine sends out a tray 9 containing PCBA boards 8 that have already been depaneled. At this time, the PCBA boards 8 on the tray 9 are located directly below the suction cup assembly 7. When this packing mechanism is working, the lifting drive unit 5, the flipping drive unit 6, and the suction cup assembly 7 work together to pick up the PCBA boards 8 from the tray 9 and flip them over so that the front of the PCBA boards 8 is facing up. Then, the XYZ three-axis drive unit 2, the rotary drive unit 3, and the gripping plate assembly 4 work together to grab the PCBA boards 8 on the suction cup assembly 7 and transfer them to the material box, thus completing the PCBA board packing operation. After flipping by the flipping drive unit 6, the back of the PCBA boards 8 in the material box can be pressed against the inner bottom surface of the material box. This packing mechanism helps to save manpower and reduce labor intensity.

[0019] It should be noted that in actual use, since the incoming material tray 9 has multiple rows of spaced PCBA board receiving slots, the PCBA depaneling machine uses a belt conveyor to control the displacement of the incoming material tray 9 to cooperate with the packing mechanism of this application to pick up the PCBA board 8. This PCBA depaneling machine and belt conveyor are prior art and are not part of the invention of this application; they are only used as an explanation of the scenario in which this application operates. In addition, the XYZ three-axis drive unit 2 is prior art and is only used here as an application. It includes two Y-axis modules that are fixed to the frame 1 and synchronously connected by a servo motor and a synchronous shaft, an X-axis backplate fixedly connected to the output ends of the two Y-axis modules, an X-axis module fixedly connected to the X-axis backplate, a Z-axis backplate fixedly connected to the output end of the X-axis module, and a Z-axis module fixedly connected to the Z-axis backplate. The rotary drive unit 3 is fixedly connected to the output end of the Z-axis module and can drive the rotary drive unit 3 to move along the XYZ direction.

[0020] Furthermore, the rotary drive unit 3 includes a first base 31 fixedly connected to the lifting end of the XYZ three-axis drive unit 2, a first stepper motor 32 fixedly connected to the first base 31, and a rotary shaft 33 fixedly connected to the output end of the first stepper motor 32. The gripper assembly 4 is fixedly connected to the end of the rotary shaft 33. The first stepper motor 32 is used to drive the rotary shaft 33 to rotate 90° so that the PCBA board 8 gripped by the gripper assembly 4 rotates 90° so as to be placed into the material box.

[0021] Furthermore, the gripper assembly 4 includes a first guide rod cylinder 41 fixedly connected to the output end of the rotary drive unit 3, a finger cylinder 42 fixedly connected to the output end of the first guide rod cylinder 41, and two gripper claws 43 fixedly connected to the finger ends of the finger cylinders 42. The first guide rod cylinder 41 is used to drive the finger cylinders 42 to move up and down, and the two gripper claws 43 cooperate to grip the PCBA board 8. In this embodiment, there are two gripper assemblies 4, which are symmetrically arranged.

[0022] Furthermore, the inner side bottom of the clamping claws 43 is provided with grooves 10 for engaging with the side edges of the PCBA board 8. The side edges of the PCBA board 8 are the same as the side edges of the PCB board. The grooves 10 of the two clamping claws 43 engage with the two side edges of the PCBA board 8 to prevent the PCBA board 8 from loosening and slipping during clamping.

[0023] Furthermore, the lifting drive unit 5 includes a second base 51 fixedly connected to the frame 1, a second guide rod cylinder 52 fixedly connected to the second base 51, a slide rail 53 fixedly connected to the side of the second base 51, and a slider 54 slidably connected to the slide rail 53. The output end of the second guide rod cylinder 52 and the slider 54 are both fixedly connected to the tilting drive unit 6. The second guide rod cylinder 52 is used to drive the tilting drive unit 6 to move up and down. The slide rail 53 and the slider 54 slide together, which helps to improve the connection stability of the tilting drive unit 6 and prevents it from easily shaking during the lifting and lowering process driven by the second guide rod cylinder 52.

[0024] Furthermore, the flipping drive unit 6 includes a third base 61 fixedly connected to the output end of the lifting drive assembly, a second stepper motor 62 fixedly connected to the third base 61, a flipping shaft 63 rotatably mounted on the third base 61 via bearings, and a synchronous belt drive 64 connecting the second stepper motor 62 and the flipping shaft 63. The shaft wall of the flipping shaft 63 is fixedly connected to one side of the suction cup assembly 7. In use, the second stepper motor 62 drives the synchronous belt drive 64 to rotate the flipping shaft 63 by 180°, so that the flipping shaft 63 drives the suction cup assembly 7 and the PCBA board 8 to flip by 180°, completing the flipping operation of the PCBA board 8. In this embodiment, the synchronous belt drive 64 includes a main synchronous pulley fixedly connected to the output end of the second stepper motor 62, a secondary synchronous pulley fixedly connected to one end of the flipping shaft 63, and a synchronous belt connecting the main synchronous pulley and the secondary synchronous pulley. This is prior art and is only used as an application here.

[0025] Furthermore, the suction cup assembly 7 includes a flip suction cup base 71 fixedly connected to the output end of the flip drive unit 6, a plurality of vacuum connectors 72 fixedly connected to the flip suction cup base 71, and a plurality of suction cup bodies 73 fixedly connected to the bottom of the flip suction cup base 71. The suction cup bodies 73 are used to pick up the PCBA boards 8 from the incoming material tray 9. Utilizing the characteristic that the back of the PCBA board 8 has a planar area, the suction cup bodies 73 are able to pick up the PCBA boards 8 from the incoming material tray 9.

[0026] Furthermore, the suction cup assembly 7 also includes two symmetrically distributed and fixedly connected to the bottom of the flip suction cup base 71, the two alignment claws 74 are used to align and abut against the two side edges of the PCBA board 8, so that the position of the PCBA board 8 can be aligned during the process of the suction cup assembly 7 pressing down to pick up the PCBA board 8, and the PCBA board 8 is avoided from being displaced and causing adverse effects on the picking operation.

[0027] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
