Description

Technical Field

[0001] This utility model relates to the field of rotary switch manufacturing technology, and in particular to an automatic cutting machine for plastic parts of circuit board rotary switches. Background Technology

[0002] After injection molding, plastic components (such as knob caps) of circuit board rotary switches inevitably retain protruding stubs or burrs at the gate. These excess plastic parts not only severely affect the smoothness and finish of the component's appearance, but more importantly, they hinder the precise assembly of the knob and switch shaft, or interfere with smooth rotation after installation, and may even scratch the user's fingers. Therefore, they must be precisely removed. Currently, common methods rely on two main approaches: one is manual trimming using blades or pliers, which is inefficient and yields inconsistent quality; the other is using simple single-station stamping or laser cutting equipment, which typically only allows for single, step-by-step operations targeting the gate or major flash.

[0003] Existing gate cutting methods have significant shortcomings: First, positioning and cutting are usually two separate processes, requiring separate drive sources (such as the drive cylinder of the positioning fixture and the drive cylinder or motor of the cutting mechanism) and complex structures. This separate design not only increases the complexity of the equipment and manufacturing costs, but also reduces efficiency due to the connection between processes. Moreover, the small waste generated by cutting often lacks an effective collection design, which easily leads to its scattering and accumulation, increasing the cleaning burden.

[0004] Therefore, it is necessary to propose an automatic cutting machine for plastic parts with circuit board knobs to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide an automatic cutting machine for plastic parts of circuit board knob switches, which can effectively solve the problems in the background art.

The end of the output shaft of the first driving source is connected to the lower side wall of the first traction plate. A cutting blade is disposed on the upper side wall of one of the first traction plates. One end of the cutting blade is provided with a cutting edge corresponding to the top of the knob switch body.

A cutting mechanism is provided at one end of the cutting base 1. The cutting mechanism includes a first driving source 9 disposed at one bottom end of the cutting base 1. The first driving source 9 is preferably a bidirectional cylinder. Positioning plates 14 for clamping the knob switch body 3 are symmetrically and movably connected on both sides of the cutting base 1 near the first driving source 9. Specifically, a groove 8 is provided on one side wall of the cutting base 1. The positioning plate 14 is movably guided and connected to the inside of the groove 8. The end of the positioning plate 14 near the knob switch body 3 is provided with an arc-shaped notch 20 that matches the side of the knob switch body 3. The positioning plate 14 is away from the knob. A groove 17 is provided on one side of the switch body 3. An adaptive plate 15 is movably connected to the groove 17. Multiple elastic elements 16 are provided between one end of the adaptive plate 15 and the inner wall of the groove 17. The elastic elements 16 are preferably springs. A first traction plate 6 is vertically provided at the end of the adaptive plate 15 away from the elastic elements 16. The output shaft end of the first drive source 9 is connected to the lower side wall of the first traction plate 6. A cutting blade 4 is provided on the upper side wall of one of the first traction plates 6. One end of the cutting blade 4 is provided with a blade 18 corresponding to the top of the rotary switch body 3. The cutting mechanism can achieve positioning and cutting of the rotary switch body 3 through a single first drive source 9. Positioning is done first and then cutting is done in one step. Moreover, the setting of the elastic elements 16 can avoid rigid clamping damage. The structure is simple and compact, and the efficiency is improved.

[0025] Furthermore, to facilitate the collection of waste materials, a receiving plate 5 is provided at the upper end of the notch 20 away from the cutting blade 4, and the receiving plate 5 is inclined. A collection groove 22 is provided at one end of the receiving plate 5. A first limiting edge 19 is provided at the end of the cutting blade 4 near the blade 18, and a second limiting edge 21 is provided at the edge of the receiving plate 5. The receiving plate 5, the collection groove 22, and the first limiting edge 19 can be used to collect the waste materials after cutting. The receiving plate 5 and the collection groove 22, together with the first limiting edge 19, can be used to collect the waste materials after cutting. The receiving plate 5 is linked with the cutting mechanism and is easy to use.

[0026] In addition, to facilitate automatic feeding and achieve automated coordination with the first drive source 9, a feeding component is provided at the end of the cutting base 1 away from the cutting mechanism. The feeding component includes a storage cylinder 2 vertically arranged at the top of one end of the cutting base 1. The inner cavity of the storage cylinder 2 is used to stack and store the rotary switch body 3. A feeding block 11 is slidably connected to the end of the conveying slide 7 near the storage cylinder 2. A through groove 13 corresponding to the feeding block 11 is provided at the bottom of the cutting base 1. A second traction plate 12 extending downward through the through groove 13 is provided at the bottom of the feeding block 11.

[0027] It should be noted that this utility model is an automatic cutting machine for plastic parts of circuit board knob switches. In use, the knob switch body 3 is stacked and stored in the storage cylinder 2. The second drive source 10 drives the loading block 11 to move via the second traction plate 12. The loading block 11 then pushes the knob switch body 3, which falls into the conveying slide 7 at the bottom, forward. The top of the loading block 11 blocks the upper knob switch body 3, preventing it from falling. This reciprocating motion allows for continuous conveying of the knob switch body 3. When the knob switch body 3 is positioned between the positioning plates 14, the first drive source 9 controls the two first traction plates 6 to move closer together. The first traction plates 6 then drive the adaptive plate 15 and the positioning plate 14 to move as a whole. The notch 20 at one end of the positioning plate 14 will... The rotary switch body 3 is clamped, and the positioning plate 14 remains stationary after clamping. The first traction plate 6 continues to move, thereby driving the adaptive plate 15 to squeeze the elastic element 16. At this time, the receiving plate 5 also remains stationary. Only the cutting blade 4 is driven by the first traction plate 6 at one end to continue moving. The cutting blade 4 then cuts the protruding part on the top of the rotary switch body 3 through the blade 18 at one end. The cut waste can be limited and blocked by the first limiting edge 19, and then pushed to the top of the receiving plate 5 by the first limiting edge 19. Finally, it is collected by the collection groove 22. Then, the first driving source 9 drives the first traction plate 6, the positioning plate 14, and the adaptive plate 15 to reset. The rotary switch body 3 continues to be pushed forward, and this cycle continues. The device of this application is small in size, simple in structure, and easy to use.
