[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figure 1-3As shown, a blister pack trimming device includes a worktable 1, with an installation groove 13 inside the worktable 1. A servo motor 7 is installed inside the worktable 1, and a double-ended screw 12 is fixedly connected to the output end of the servo motor 7. Both ends of the double-ended screw 12 are rotatably connected inside the installation groove 13. The surface of the double-ended screw 12 has two threads in opposite directions, which respectively form a threaded engagement with two sliders 8. The outer walls of the two sliders 8 are slidably connected inside the installation groove 13. A connecting post 9 is rotatably connected to one end of the slider 8. Push blocks 10 are fixedly connected to both ends of the connecting post 9. A fixing post 11 is fixedly connected to one end of the two push blocks 10. A connecting block 6 is rotatably connected to the top of the fixing post 11. A placement block 3 is fixedly connected to one side of the outer wall of the connecting block 6. The outer wall of the connecting block 6 is slidably connected inside the installation groove 13. The outer wall of the placement block 3 is located inside the installation groove 13, and the outer wall of the push block 10 is located inside the installation groove 13.

[0024] Specifically, the servo motor 7 is fixed by the worktable 1, and the servo motor 7 drives the double-ended screw 12 to rotate. The worktable 1 restricts both ends of the double-ended screw 12 to prevent it from deviating during rotation. The double-ended screw 12 drives the slider 8 to rotate, and the worktable 1 restricts one end of the slider 8 to prevent it from rotating with the double-ended screw 12, so that the slider 8 can only move in a straight line along the double-ended screw 12. The slider 8 and the push block 10 are connected by the connecting post 9, so that the slider 8 can drive one end of the push block 10 to move. This allows the connecting block 6 connected to the fixed post 11 to slide inside the worktable 1, thereby moving the placement block 3 through the connecting block 6, and adjusting the extension distance of the placement block 3.

[0025] Reference Figure 3As shown, multiple support columns 5 are fixedly connected to the lower surface of the workbench 1. Support columns 14 are fixedly connected to one side of the outer wall of each support column 5, forming a triangular support structure. A through-type sliding groove 23 is opened inside the support column 14. A linear motor 15 is installed inside the support column 14, located within the sliding groove 23. A fixing plate 16 is fixedly connected to the upper surface of the linear motor 15. A vacuum pump 17 is fixedly connected to the upper surface of the fixing plate 16. The output end of the vacuum pump 17 is connected to a gas supply pipe 18. The fixing plate 16... A cylinder 19 is mounted on the upper surface of plate 6. A fixing block 20 is fixedly connected to the output end of cylinder 19. One end of the air supply pipe 18 is connected to the platform 4. A fixing block 37 is fixedly connected to one side of the outer wall of fixing block 20. Multiple limiting posts 36 are slidably connected inside fixing block 37. The bottom ends of the multiple limiting posts 36 are fixedly connected to the upper surface of fixing plate 16. The other end of the air supply pipe 18 is connected to the interior of the platform 4. The surface of the platform 4 is provided with honeycomb-shaped adsorption holes. The air supply pipe 18 communicates with the adsorption holes through an air distribution chamber. A servo motor 22 is installed inside fixing block 37. The output end of servo motor 22 is fixedly connected to the lower surface of the platform 4. A sealing ring 21 is fixedly connected to the upper surface of the platform 4.

[0026] Specifically, the worktable 1 is supported by the support column 5, and the support column 14 is fixed below the worktable 1 by multiple placement blocks 3. The position of the linear motor 15 is restricted by the sliding groove 23 on the support column 14. The linear motor 15 can drive the fixed plate 16 to move. The cylinder 19 installed on both sides of the fixed block 37 drives the fixed block 37, which is connected to the screw 29, to move up and down. The air supply pipe 18 connects the placement table 4 and the output end of the vacuum pump 17, so that the gas inside the placement table 4 can be extracted by the vacuum pump 17. The vacuum pump 17 is a dry rotary vane pump with an ultimate vacuum of -90kPa and a pumping rate of 12L / min. It is equipped with a vacuum pressure sensor for real-time monitoring. The movement direction of the fixed block 37 is restricted by the limiting column 36 inside the fixed block 37 to prevent the fixed block 37 from deviating during movement. The sealing ring 21 on the placement table 4 can stably fix the tooling on the placement table 4.

[0027] Reference Figure 4As shown, a support frame 2 is fixedly connected to the upper surface of the workbench 1. A cylinder 24 is installed at the top of the inner cavity of the support frame 2. A clamping plate 25 is rotatably connected to the output end of the cylinder 24. A sealing ring 26 is fixedly connected to the lower surface of the clamping plate 25. A servo motor 28 is installed inside the support frame 2. A lead screw 29 is fixedly connected to the output end of the servo motor 28. A slider 30 is threadedly connected to the outer wall of the lead screw 29. A limit post 27 is fixedly connected to the outer wall of the support frame 2. The inner wall of the slider 30 is slidably connected to the outer wall of the limit post 27. A top plate 34 is fixedly connected to one end of the limit post 27. One end of the lead screw 29 is rotatably connected to one side of the outer wall of the top plate 34. A mounting block 31 is fixedly connected to the outer wall of the slider 30. A rotary motor 35 is installed on the outer wall of the mounting block 31. A turntable 32 is fixedly connected to the output end of the rotary motor 35. A cutting wire 33 is provided on the outer wall of the turntable 32.

[0028] Specifically, the workbench 1 supports the support frame 2, ensuring stable operation of the structure on the support frame 2. The support frame 2 fixes the cylinder 24, which in turn drives the clamping plate 25 to move up and down, providing stable clamping for the tooling. The workbench 1 also fixes the servo motor 28, which drives the lead screw 29 to rotate, thus rotating the slider 30 on the lead screw 29. The position of the slider 30 is limited by the limiting posts 27 installed on both sides of the lead screw 29, thereby allowing the slider to move. Block 2 30 can only move horizontally and will not rotate with the lead screw 29. At the same time, the top plate 34 blocks the limiting post 27 and one end of the lead screw 29, thereby preventing the slider 2 30 from falling off the lead screw 29. The movement of the slider 2 30 drives the mounting block 31 to move, and the rotary motor 35 on the mounting block 31 drives the turntable 32 inside the mounting block 31 to rotate, thereby driving the cutting wire 33 on the turntable 32 to rotate. The high-speed rotating cutting wire 33 cuts the edge of the tooling. The rotation of the lead screw 29 drives the mounting block 31 to move, thus enabling the processing of different types of tooling.

[0029] Working Principle: In use, the servo motor 7 inside the worktable 1 drives the double-headed screw 12 to rotate, which in turn drives the slider 8 inside the double-headed screw 12 to move. The worktable 1 restricts the slider 8 to linear motion only. Simultaneously, the moving slider 8 drives the connecting post 9 and the push block 10 connected to the connecting post 9 to move. The push block 10 pushes the connecting block 6 connected to the fixed post 11 to move inside the mounting groove 13, and the connecting block 6 causes the placement block 3 to extend out. Meanwhile, the tooling is fed to the placement block 3 by the feeding device, so that the placement block 3 can lift different tooling. At the same time, the cylinder 19 on the fixing plate 16 is started, and the output end of the cylinder 19 pushes the fixing block 20 and the fixing block 27 connected to the fixing block 20 to move up and down, thereby driving the placement platform 4 above the fixing block 237 to move below the tooling. At the same time, the vacuum pump 17 on the fixing plate 16 is started, and the gas between the placement platform 4 and the tooling is extracted through the gas supply pipe 18, so that the tooling can be adsorbed on the placement platform 4.

[0030] The linear motor 15 on the support column 14 moves, which drives the fixed plate 16 to move on the support column 14, thereby moving the fixed plate 16 and the tooling fixed on the fixed plate 16. At the same time, the cylinder 24 installed below the support frame 2 drives the clamping plate 25 to move downward. The cylinder 24 and the platform 4 clamp and fix the tooling. The sealing ring 21 installed on the platform 4 and the sealing ring 26 installed on the clamping plate 25 fix and protect the tooling, preventing it from falling off during movement and preventing the tooling from shifting when the platform 4 and the clamping plate 25 rotate.

[0031] After moving to the desired position, the servo motor 22 installed in the fixed block 2 37 starts, driving the upper platform 4 to rotate, which in turn drives the tooling clamped between the platform 4 and the clamping plate 25 to rotate. At the same time, the servo motor 3 28 on the support frame 2 drives the lead screw 29 to rotate, which in turn drives the slider 2 30 and the mounting block 31 connected to the slider 2 30 to move toward the tooling. During the movement, the rotary motor 35 on the mounting block 31 starts, which drives the turntable 32 in the middle of the mounting block 31 to rotate, which in turn drives the cutting wire 33 to run. Finally, the tooling is cut by the high-speed cutting wire 33. While the tooling is rotating, the servo motor 3 28 drives the mounting block 31 and the cutting wire 33 to move. By adjusting the movement trajectory of the cutting wire 33, it can be made to cut along the edge of the tooling, thus facilitating the cutting of different types of tooling.
