Specific embodiments
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1 to 8, the present utility model provides a technical solution: an automatic PCBA board stacking machine, including a conveyor 1. There is a support frame 2 on one side of the conveyor 1. Both sides of the support frame 2 are fixedly connected with side bracket bodies 3. An inner support plate 6 is fixedly connected between the two side bracket bodies 3. A first cylinder 8 is installed at the bottom of the inner support plate 6. The output end of the first cylinder 8 is fixedly connected with a first adjusting plate 7 that cooperates with the conveyor 1. A second cylinder 10 is installed inside the first adjusting plate 7. The output end of the second cylinder 10 is fixedly connected with a lifting plate 11. A receiving and lifting groove that cooperates with the lifting plate 11 is opened at the top of the first adjusting plate 7. A connection box 14 is fixedly connected inside the support frame 2. A bidirectional lead screw 16 is rotatably connected inside the connection box 14. Two second adjusting plates 17 are symmetrically threadedly connected to the outside of the bidirectional lead screw 16. The second adjusting plates 17 are slidably connected with the connection box 14 and slidably connected with the support frame 2. A support and fixing box 18 is fixedly connected to one side of each of the two second adjusting plates 17. A sliding plate 20 is slidably connected inside the support and fixing box 18. An inclined side limiting block 19 is fixedly connected to one side of the sliding plate 20. Second side baffles 5 are fixedly connected to the tops of the two support and fixing boxes 18. The top parts of the two inclined side limiting blocks 19 are used to limit and stack each PCBA board, realizing the work of automatic board stacking and supporting and stacking each PCBA board at the top.
[0024] Among them, side support frame bodies 22 are fixedly connected to both sides of the conveyor 1.
[0025] Among them, two first limiting slide bars 9 are symmetrically and fixedly connected to the bottom of the first adjusting plate 7. Both of the two first limiting slide bars 9 are slidably connected with the inner support plate 6. The movement and adjustment position of the first adjusting plate 7 are restricted by the two first limiting slide bars 9, improving the stability of the adjustment.
[0026] Among them, two second limiting slide bars 12 are symmetrically and fixedly connected to the bottom of the lifting plate 11. Both of the two second limiting slide bars 12 are slidably connected with the first adjusting plate 7. The movement and adjustment position of the lifting plate 11 are restricted by the two second limiting slide bars 12, improving the stability of the adjustment.
[0027] Among them, two first side baffles 4 are symmetrically and fixedly connected to the inner side of the support frame 2. The positions of each PCBA board during stacking are limited by the two first side baffles 4 and the two second side baffles 5, improving the stability of the stacking.
[0028] Among them, a rotating knob 15 is rotatably connected to one side of the connection box 14. One end of the bidirectional lead screw 16 is fixedly connected with the rotating knob 15. The bidirectional lead screw 16 is rotationally adjusted by the rotating knob 15, and the positions of the two second adjusting plates 17 on the outside are adjusted by the rotation of the bidirectional lead screw 16.
[0029] Among them, a limiting plate 13 is fixedly connected to the top of the first adjusting plate 7. The limiting plate 13 is used to limit the position of the PCBA board reaching the first adjusting plate 7, improving the stability.
[0030] Among them, two reset springs 21 are symmetrically and fixedly connected to the side of the sliding plate 20 away from the hypotenuse limiting block 19. One end of the reset spring 21 is fixedly connected to the support fixing box 18. The two reset springs 21 are used to reset the moved sliding plate 20 and reset the moving positions of the sliding plate 20 and the hypotenuse limiting block 19.
[0031] Specifically, during use, the output end of the second cylinder 10 drives the jacking plate 11 into the receiving jacking groove. By rotating the rotating knob 15, when the rotating knob 15 rotates, it drives the bidirectional lead screw 16 to rotate. When the bidirectional lead screw 16 rotates, it drives the two second adjusting plates 17 and the support fixing box 18 to move, adjusting the distance between the two support fixing boxes 18 to adapt to the size of the PCBA board. The PCBA board is conveyed by the conveyor 1 and conveyed to the jacking plate 11 in the receiving jacking groove at the top of the first adjusting plate 7. The limiting plate 13 limits the position of the PCBA board. The output end of the first cylinder 8 drives the first adjusting plate 7, the second cylinder 10 and the jacking plate 11 to move upward to lift the PCBA board as a whole. When reaching the bottom of the support frame 2, the output end of the second cylinder 10 jacks the jacking plate 11 upward to jack the PCBA board. When the jacking plate 11 jacks the PCBA board to the hypotenuse limiting block 19, at this time, the reset spring 21 resets and drives the sliding plate 20 and the hypotenuse limiting block 19 to move inward for reset. The position of the PCBA board is limited by the two hypotenuse limiting blocks 19. Each subsequent PCBA board jacks the two hypotenuse limiting blocks 19 and jacks the PCBA board at the top, and the stacking of the boards can be completed.
