[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0034] Please see Figures 1 to 6 As shown, this embodiment is a trimming device for producing mobile phone mid-frames, comprising:

[0035] The device includes a trimming table 11, an operating table 12, and a placement table 15. The operating table 12 is fixed to the upper surface of the trimming table 11, and the placement table 15 is fixed to the center of the upper surface of the operating table 12. A support frame 13 is fixed to one side of the operating table 12, and a trimming head 14 is movably installed on one side of the support frame 13. A mobile phone frame 16 is placed on the upper surface of the placement table 15. Circular holes 17 are opened on both sides of the placement table 15. A threaded rod 18 is threaded through the inside of the circular hole 17. A rubber block 19 is fixed to one end of the threaded rod 18, and one side of the rubber block 19 is in contact with the mobile phone frame 16.

[0036] The threaded rod 18 converts rotational motion into linear motion, enabling precise movement of the rubber block 19. The rubber block 19 provides cushioning when it contacts the phone frame 16, reducing potential damage to the phone frame 16.

[0037] The positioning assembly includes a square groove 21, a straight groove 211, a motor 22, a lead screw 23, a positive thread groove 24, and a negative thread groove 25. The square groove 21 is opened inside the operating table 12, and the two straight grooves 211 are opened on both sides of the upper surface of the operating table 12, and the square groove 21 and the straight grooves 211 are interconnected. The motor 22 is fixed on one side of the operating table 12, and the lead screw 23 is fixed at the output end of the motor 22, and the lead screw 23 passes through the inside of the square groove 21. The positive thread groove 24 is opened on one side of the lead screw 23, and the negative thread groove 25 is opened on the other side of the lead screw 23.

[0038] The square slot 21 is opened inside the operating table 12, providing the necessary internal space for the lead screw 23 and other transmission components. The straight slot 211 provides a guide for the lead screw 23, ensuring that it can maintain the correct position when rotating. The motor 22 is the power source of the entire positioning assembly. Its rotation drives the lead screw 23 to move the positioning plate. The positive thread slot 24 and the negative thread slot 25 allow the two positioning plates to move relative to each other, thereby achieving precise clamping of the mobile phone frame 16.

[0039] The outer surface of the positive threaded groove 24 is threaded through the first positioning plate 26, and the outer surface of the negative threaded groove 25 is threaded through the second positioning plate 27. The first positioning plate 26 and the second positioning plate 27 are in contact with the outer surface of the mobile phone frame 16. The square groove 21 is fixed with a limit post 28, and the first positioning plate 26 and the second positioning plate 27 penetrate the outer surface of the limit post 28. The lower surface of the motor 22 is fixed with a support platform 221. The lead screw 23 is positively aligned with the straight groove 211 on the front side, and the limit post 28 is positively aligned with the straight groove 211 on the rear side.

[0040] The first positioning plate 26 and the second positioning plate 27 are in direct contact with the mobile phone frame 16. Their movement enables precise positioning of the mobile phone frame 16. The limiting post 28 is used to fix the first positioning plate 26 and the second positioning plate 27 to prevent them from shifting during operation.

[0041] Working principle:

[0042] After placing the phone frame 16 into the placement platform 15, the threaded rod 18 is rotated. The threaded rod 18 rotates on both sides of the placement platform 15, simultaneously driving the rubber block 19 to move inward, thus fixing the phone frame 16 in the placement platform 15. Then, the motor 22 is started through the external controller. The motor 22 drives the lead screw 23 to rotate. The rotation of the lead screw 23 simultaneously drives the positive thread groove 24 and the negative thread groove 25 to rotate relative to each other. The positive thread groove 24 and the negative thread groove 25 simultaneously drive the first positioning plate 26 and the second positioning plate 27 to move relative to each other. The first positioning plate 26 and the second positioning plate 27 move towards the center simultaneously, positioning the phone frame 16 at the center of the placement platform 15.

[0043] This step, through the linkage of motor 22 and lead screw 23, achieves automatic positioning of the mobile phone frame 16, reduces manual intervention, improves production efficiency and quality, and enhances operational safety.

[0044] Please see Figures 1 to 6 As shown; this embodiment, based on the above embodiment, further includes:

[0045] The collection component includes a drain hole 31, a mounting groove 32, a limiting groove 33, a collection frame 34, and a slider 35. The drain hole 31 is opened on the lower surface of the operating table 12. The mounting groove 32 is opened on one side of the trimming table 11. The limiting groove 33 is opened on both sides inside the mounting groove 32. The collection frame 34 is slidably installed inside the mounting groove 32. The slider 35 is fixed on both sides of the bottom of the collection frame 34. A collection groove 341 is opened on one side inside the collection frame 34. A connecting rod 36 slides through one side of the collection frame 34. A connecting plate 37 is fixed to one end of the connecting rod 36 and the connecting plate 37 is located inside the collection frame 34.

[0046] The drain hole 31 is opened on the lower surface of the operating table 12 to provide a channel for the debris to fall. The mounting groove 32 is used to fix the collection frame 34 to ensure its stability during operation. The collection frame 34 is a container for storing debris. It is designed to be pull-out for easy cleaning by the staff. One end of the connecting rod 36 is fixed with a connecting plate 37. When the connecting rod 36 moves, the connecting plate 37 can push the debris inside the collection frame 34 to one side.

[0047] Working principle:

[0048] After the phone frame 16 is trimmed, the debris from the phone frame will fall into the collection box 34 through the straight slot 211 and the drain hole 31. The staff only needs to pull the collection box 34 out of the mounting slot 32, and then pull out the connecting rod 36. The connecting rod 36 drives the connecting plate 37 to move. The connecting plate 37 pushes the debris inside the collection box 34 to one side until the connecting plate 37 moves towards the collection slot 341, so that the debris falls from the collection slot 341, which facilitates the collection of debris.

[0049] In this step, the pull-out design of the collection box 34 and the simple operation of the connecting rod 36 make it easy for staff to carry out cleaning work, making equipment maintenance and cleaning simpler and faster.
