[0024] Embodiment

[0025] Please refer to Figures 1-5, the present utility model provides a technical solution: a frictionless lifting and board-splitting mechanism, including a first support frame 1 and a second support frame 2. A guide post 3 is fixedly connected between the first support frame 1 and the second support frame 2. A sliding seat 4 is slidably connected to the outside of the guide post 3. The top of the sliding seat 4 is provided with two support plates 5. The bottom of the support plate 5 is provided with a cylinder 6. The piston rod of the cylinder 6 extends to the top of the support plate 5 and is fixedly connected with a mounting frame 7. The top of the mounting frame 7 is fixedly connected with a plurality of support plates 8. The top of the plurality of support plates 8 is provided with rubber pads 9. Connecting components are arranged on the plurality of support plates 8. The bottom of the first support frame 1 and the second support frame 2 is provided with a driving component; when two PCB boards respectively move above the two support plates 8, the piston rod of the cylinder 6 is pushed to move the mounting frame 7 upward, so that the two support plates 8 simultaneously lift the two PCB boards. At this time, the rubber pad 9 abuts against the bottom of the PCB board, which can avoid scratching the surface of the PCB board.

[0026] In order to facilitate the replacement and installation of the rubber pad 9; the connecting component includes two mounting blocks 15, a threaded rod 16 and a first L-shaped block 17. The top of the support plate 8 is provided with two long through slots 14. The two mounting blocks 15 are fixedly connected to the inner top of the support plate 8. The threaded rod 16 is rotatably connected to the mounting block 15. The first L-shaped block 17 is movably sleeved on the outside of the threaded rod 16. The first L-shaped block 17 is slidably connected to the inside of the long through slot 14. One end of the threaded rod 16 extends to the outside of the mounting block 15 and is fixedly connected with a connecting column 18. One end of the connecting column 18 is provided with a hexagonal groove. Both ends of the bottom of the rubber pad 9 are fixedly connected with a second L-shaped block 19. Opposite thread sections are arranged at both ends of the outside of the threaded rod 16. The first L-shaped block 17 is threadedly connected to the outside of the threaded rod 16; by reversely rotating the connecting column 18 with an internal hexagon wrench, the connecting column 18 drives the threaded rod 16 to rotate, so that the threaded rod 16 drives the two first L-shaped blocks 17 to move inside the long through slot 14. At the same time, the two first L-shaped blocks 17 approach each other, so that the first L-shaped block 17 disengages from one side of the second L-shaped block 19, and the rubber pad 9 can be disassembled and replaced, which is time-saving and labor-saving;

[0027] The second L-shaped block 19 penetrates through the inside of the long through slot 14 and abuts against one end of the first L-shaped block 17; by placing the rubber pad 9 on the top of the support plate 8, the second L-shaped block 19 is placed inside the long through slot 14, and then the connecting column 18 is rotated forward with an internal hexagon wrench. The connecting column 18 drives the threaded rod 16 to rotate, so that one end of the first L-shaped block 17 abuts against one end of the second L-shaped block 19, thereby pushing the other end of the second L-shaped block 19 to abut against one end of the long through slot 14, and the installation of the rubber pad 9 can be completed.

[0028] To achieve rapid and stable adjustment of the PCB board position, the driving assembly includes two servo motors 10 and two pulleys 11. The two servo motors 10 are both installed at the bottom of the first support frame 1. The two pulleys 11 are respectively fixedly connected to the output shafts of the two servo motors 10. The outer sides of the two pulleys 11 are respectively provided with a first belt 12 and a second belt 13. Both ends of the first belt 12 are fixedly connected to the bottom of one of the right support plates 5, and both ends of the second belt 13 are fixedly connected to the bottom of one of the left support plates 5. By driving the two pulleys 11 to rotate respectively through the output shafts of the two servo motors 10, the two pulleys 11 drive the two ends of the first belt 12 and the second belt 13 to move, so that the first belt 12 and the second belt 13 drive the two support plates 5 to move away from each other respectively. At this time, the support plates 8 on the mounting frame 7 drive the two PCB boards to separate respectively, and move the PCB boards to the corresponding positions.

[0029] In terms of the working principle or structural principle, when the two PCB boards are respectively moved above the two support plates 8, the solenoid valve of the cylinder 6 is controlled to open through the switch group. The piston rod of the cylinder 6 pushes the mounting frame 7 to move upward, so that the two support plates 8 lift the two PCB boards at the same time. At this time, the rubber pad 9 abuts against the bottom of the PCB board, which can avoid scratching the surface of the PCB board. Then, the two servo motors 10 are controlled to start through the switch group. The output shafts of the two servo motors 10 drive the two pulleys 11 to rotate respectively. The two pulleys 11 drive the two ends of the first belt 12 and the second belt 13 to move, so that the first belt 12 and the second belt 13 drive the two support plates 5 to move away from each other respectively. At this time, the support plates 8 on the mounting frame 7 drive the two PCB boards to separate respectively, and move the PCB boards to the corresponding positions, achieving rapid and stable adjustment of the PCB board position;

[0030] When the rubber pad 9 needs to be replaced, the connecting column 18 is rotated counterclockwise by an inner hexagon wrench. The connecting column 18 drives the threaded rod 16 to rotate, so that the threaded rod 16 drives the two first L-shaped blocks 17 to move inside the long through groove 14. At the same time, the two first L-shaped blocks 17 approach each other, so that the first L-shaped blocks 17 disengage from one side of the second L-shaped block 19, and then the rubber pad 9 can be disassembled. The operation is simple and fast. When installing, the rubber pad 9 is placed on the top of the support plate 8, so that the second L-shaped block 19 is placed inside the long through groove 14. Then the connecting column 18 is rotated clockwise by an inner hexagon wrench. The connecting column 18 drives the threaded rod 16 to rotate, so that one end of the first L-shaped block 17 abuts against one end of the second L-shaped block 19, thereby pushing the other end of the second L-shaped block 19 to abut against one end of the long through groove 14, and then the installation of the rubber pad 9 can be completed.
