[0002] Silicone buttons are functional button products made of silicone as the core material. With their excellent heat resistance, cold resistance and fatigue resistance, they are widely used in various consumer electronic devices such as electronic calculators, remote controls, and telephones. In the mass production process, due to the limitations of the multi-cavity mold layout process, the molded silicone buttons will be connected into a whole row of material sheets through the process ribs. Therefore, they must be precisely separated into individual finished products through the cutting process.

[0003] When operating the existing silicone button contour precision cutting equipment, the button to be processed needs to be placed manually at the processing station at the bottom of the precision cutting machine. This operating space is adjacent to the running area of ​​the precision cutting tool, and there are safety hazards such as mechanical scratches and accidental contact with the tool when workers manually pick up and place the button. At the same time, the manual alignment and reinforcement process is cumbersome, the efficiency of clamping and reinforcement in a single batch is low, and the existing tooling structure lacks an adjustable and adaptable design, which cannot be compatible with the co-line processing of silicone buttons of different specifications and sizes. Therefore, improvements are needed. Summary of the Invention

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1-9 This embodiment provides a precision cutting device for silicone button contours that can be adapted to multiple specifications. It can achieve precision cutting of silicone buttons of various specifications and has an automatic unloading function. It includes: a cutting component 100, which includes a moving component 200 that slides in the middle of the cutting component 100, four support components 300 that slide inside the moving component 200, a shrinking component 400 fixed to the outside of the support components 300, a synchronization component 500 that rotates on the outer wall of the moving component 200 corresponding to the bottom of the support components 300, the support components 300 and the synchronization component 500 being rotatably connected, an elastic component 600 that slides in the top of the moving component 200 corresponding to the synchronization component 500, a limiting component 700 fixed between the moving component 200 and the elastic component 600, a reset component 800 fixed inside the cutting component 100 at the end of the moving component 200, and a prompting component 900 fixed on the top right side of the moving component 200.

[0030] Specifically, the cutting assembly 100 includes a worktable 101 with a track at the front end and a positioning groove 102 on the top right side of the worktable 101. The positioning groove 102 is recessed and adapted to position a ball. There are three positioning grooves 102, which are a loading area, a processing area, and an unloading area from front to back. A storage box can be placed at the bottom of the unloading area located in the positioning groove 102 for collection. A precision cutting device 103 is fixed to the top rear end of the worktable 101. The precision cutting device 103 is used for precision cutting of silicone buttons.

[0031] Furthermore, the movable component 200 includes a movable plate 201 that slides on the open end of the worktable 101, an equipment disk 202 fixed in the middle of the movable plate 201, an arc-shaped groove 203 on the outer side of the top of the equipment disk 202, the arc of the arc-shaped groove 203 being consistent with the annular shape of the equipment disk 202, and recessed grooves 204 at the four ends of the opening of the equipment disk 202, the recessed grooves 204 being used to install the support component 300.

[0032] Furthermore, the support assembly 300 includes a sliding plate 301 that slides at the four ends of the recessed groove 204 at the opening of the equipment tray 202, a baffle 302 fixed to the inner side of the sliding plate 301, and a support plate 303 fixed to the inner side of the baffle 302. The reserved position of the recessed groove 204 is adapted to the baffle 302 and the support plate 303. The retraction assembly 400 includes an arc-shaped plate 401 fixed to the outer side of the sliding plate 301, and an elastic ring 402 set on the outer wall of the arc-shaped plate 401 corresponding to the outer wall of the equipment tray 202. The elastic ring 402 can simultaneously apply inward compressive force to the four arc-shaped plates 401. The synchronization assembly 500 includes a track plate 501 that rotates on the outer wall of the equipment tray 202 corresponding to the bottom of the sliding plate 301. The track plate 501 is provided with a synchronization groove 502 at the sliding plate 301 for synchronization. The groove 502 consists of four arc-shaped inclined grooves located at the bottom of the corresponding slide plate 301. The end face of the track disk 501 is provided with a reserved groove 503 at the bottom of the corresponding arc-shaped groove 203. The slide rod 504 slides in the synchronization groove 502. The top of the slide rod 504 is rotatably connected to the bottom of the slide plate 301. In use, by rotating the track disk 501, the four slide rods 504 located in the synchronization groove 502 can be driven to move inward or outward. The slide rods 504 can drive the slide plate 301, baffle 302, and support plate 303 to be adjusted synchronously, so as to be able to adapt to the centering positioning of silicone buttons of various sizes, and thus adapt to the processing of silicone buttons of various sizes. During this process, the elastic ring 402 can also apply inward pressure to the slide plate 301, baffle 302, support plate 303, and slide rod 504.

[0033] Furthermore, the elastic component 600 includes a protruding rod 601 sliding within the arc-shaped groove 203. The protruding rod 601 initially abuts against the left side of the reserved groove 503. The bottom of the protruding rod 601 is a small end, and the top slides within the arc-shaped groove 203. A connecting block 602 slides on the top of the protruding rod 601, and a tension spring 603 is fixed between the protruding rod 601 and the connecting block 602. The limiting component 700 includes an arc-shaped groove plate 701 fixed to the top of the equipment tray 202 corresponding to the arc-shaped groove 203. The top of the arc-shaped groove plate 701 has a limiting groove 702, which is arranged in an arc-shaped array. A locking plate 703 is located within the limiting groove 702. The top of the locking plate 703 is fixedly connected to the top of the connecting block 602. In use, by pulling the locking plate 703 upwards... 3. When disengaging from the limiting groove 702, the locking plate 703 drives the connecting block 602 and pulls the tension spring 603 upward. Simultaneously, moving the locking plate 703 can drive the connecting block 602. Since the protruding rod 601 is in contact with the left side of the reserved groove 503, the protruding rod 601 can drive the track disk 501 to rotate to the left. When it is necessary to drive the track disk 501 to rotate to the right, simply move the protruding rod 601 to the right. Because the elastic ring 402 applies inward pressure to the slide plate 301, baffle 302, support plate 303, and slide rod 504, the slide rod 504 will squeeze the synchronous groove 502 to drive the track disk 501 to rotate to the right. Therefore, the bottom of the protruding rod 601 can still contact the left side of the reserved groove 503. When the track disk 501 rotates, it will adjust the support component 300 to center the silicone button.

[0034] Furthermore, the reset assembly 800 includes a reset block 801 fixed to the inner side of the movable plate 201 at the opening of the workbench 101. The reset block 801 has a guide groove 802 at one end of the movable plate 201. The guide groove 802 is inclined, and its inlet is located at the minimum end of the synchronization groove 502, allowing the slide rod 504 to enter. The reset block 801 has a groove 803 at the end of the guide groove 802. The prompting assembly 900 includes a fixing block 901 fixed to the top right side of the movable plate 201, a round rod 902 sliding at the bottom of the fixing block 901, and a mechanism fixed to the fixing block 901 and the round rod 902. The spring 903 between the round rod 902 and the ball 904 rolling at the bottom of the round rod 902 are adapted to the loading area, processing area and unloading area of ​​the positioning groove 102. In use, when the moving plate 201 is at the front end of the precision cutting equipment 103, the ball 904 is located in the loading area of ​​the positioning groove 102. Because the spring 903 squeezes the round rod 902 and the ball 904, the ball 904 can abut against the recess of the positioning groove 102, so a positioning effect can be formed. After loading is completed, the moving plate 201 is pushed to drive the subsequent structure until the ball 904 moves to the processing area of ​​the positioning groove 102. At this time, the precision cutting equipment 103 is in operation. 03 The silicone button can be processed. After processing, the plate 201 is moved again to drive the subsequent structure until the ball 904 enters the unloading area of ​​the positioning groove 102. When entering the unloading area, the left and right slide rods 504 will enter the guide groove 802 of the reset block 801, causing the two slide rods 504 to move outward until the slide rods 504 enter the groove 803. At this time, the two slide rods 504 can drive the track plate 501 to rotate to the left through the synchronous groove 502. The other two slide rods 504 will also move synchronously due to the synchronous groove 502 until the slide rods 504 move to the outer end of the synchronous groove 502. During this process, the slide rods 504 can carry The sliding plate 301, baffle 302, and support plate 303 enter the recessed groove 204, causing the processed silicone button to detach from the support and fall downwards. A receiving bucket can be set at the bottom to catch the material. During this process, the bottom of the protruding rod 601 is located on the left side of the reserved groove 503, so it does not affect the leftward movement of the track plate 501. After unloading is completed, the moving plate 201 is pulled back to the loading area. The elastic ring 402 will drive the arc plate 401, sliding plate 301, baffle 302, and support plate 303 to move inwards. At the same time, the sliding plate 301 will also drive the sliding rod 504 and track plate 501 to reset, so that the processing of subsequent silicone buttons can continue.

[0035] During use, before processing the silicone buttons, the locking plate 703 can be pulled upwards to disengage from the limiting groove 702. At this time, the locking plate 703 drives the connecting block 602 and pulls the tension spring 603 upwards. Simultaneously, moving the locking plate 703 can drive the connecting block 602. Since the protruding rod 601 is in contact with the left side of the reserved groove 503, the protruding rod 601 can drive the track disk 501 to rotate to the left. When it is necessary to drive the track disk 501 to rotate to the right, simply move the protruding rod 601 to the right. Because the elastic ring 402 applies inward pressure to the slide plate 301, baffle 302, support plate 303, and sliding rod 504, the sliding rod 504 will squeeze the synchronous groove 502, causing the track disk 501 to rotate to the right. Therefore, the bottom of the protruding rod 601 can still contact the left side of the reserved groove 503. By rotating the track disk 501, the track disk 501 can rotate to the right. 01 can drive four sliding rods 504 located in the synchronous groove 502 to move inward or outward. The sliding rods 504 can drive the slide plate 301, baffle 302, and support plate 303 to perform synchronous adjustment, thereby adapting to the centering and positioning of silicone buttons of various sizes, and thus adapting to the processing of silicone buttons of various specifications. During this process, the elastic ring 402 can also apply inward pressure to the slide plate 301, baffle 302, support plate 303, and sliding rods 504, thereby adapting to the processing of silicone buttons of various specifications. When the moving plate 201 is at the front end of the precision cutting equipment 103, the ball 904 is located in the feeding area of ​​the positioning groove 102. Because the spring 903 squeezes the round rod 902 and the ball 904, the ball 904 can abut against the recess of the positioning groove 102, thus forming a... To achieve a positioning effect, after the material is loaded, the moving plate 201 is pushed to drive the subsequent structure until the ball bearing 904 moves to the processing area of ​​the positioning groove 102. At this time, the precision cutting equipment 103 can process the silicone button. After processing, the moving plate 201 is moved again to drive the subsequent structure until the ball bearing 904 enters the unloading area of ​​the positioning groove 102. When entering the unloading area, the left and right slide rods 504 will enter the guide groove 802 of the reset block 801, causing the two slide rods 504 to move outward until the slide rods 504 enter the groove 803. At this time, the two slide rods 504 can drive the track disk 501 to rotate to the left through the synchronous groove 502. The other two slide rods 504 will also move synchronously due to the synchronous groove 502 until the slide rods 504 move to the outer end of the synchronous groove 502. During the process, the slide bar 504 can drive the slide plate 301, baffle 302, and support plate 303 into the recessed groove 204, causing the processed silicone button to detach from the support and fall downwards. A receiving bucket can be set at the bottom to catch the material. During this process, the bottom of the protruding rod 601 is located on the left side of the reserved groove 503, so it does not affect the leftward movement of the track plate 501. After unloading is completed, the moving plate 201 is pulled back to the loading area. The elastic ring 402 will drive the arc plate 401, slide plate 301, baffle 302, and support plate 303 to move inwards. At the same time, the slide plate 301 will also drive the slide bar 504 and track plate 501 to reset, so that the processing of subsequent silicone buttons can continue. In the above process, the spring 903 compresses the round rod 902 and the ball 904 into the positioning groove.The impact force of the ball bearing 904 entering the positioning groove 102 can generate an audible alert and also provide a positioning effect.

[0036] In summary, this invention realizes a movable silicone button support base. The base can achieve precise positioning and movement in three stages, with the three stages corresponding to the button loading position, the precision cutting position, and the rapid unloading position, respectively. The entire operation only requires the worker to perform a simple push-pull operation, without having to reach into the tool running area to place the button, thus fundamentally avoiding the safety risks of close-range manual operation. At the same time, the base is equipped with dedicated positioning prompts at each process node of the three-stage movement, making the operation status of each step clearly identifiable. Therefore, it has the advantages of safe loading, precise processing, and rapid unloading.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
