It is widely used in the mass production of electronic equipment keys.

[0003] When cutting circular silicone keys, in some existing technologies, the cutter is cylindrical with a sharp end at the bottom, and is set to fit the shape of the edge of the silicone key. The cutter is pressed up and down on the entire silicone key to separate the silicone key parts. During the downward pressure of the cutter, when the silicone is placed on the platform and is subjected to the downward pressure of the cutter, it will be pulled and squeezed and deformed due to its soft texture and high flexibility, rather than breaking neatly, resulting in a large number of torn edges on the edges and uneven burrs on the edges of the silicone key.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 10 As shown, the present invention provides a burr-free slitting device for a whole sheet of silicone keypads, comprising a placement plate 100, and further comprising: a slitting mechanism 200, the slitting mechanism 200 comprising a driving assembly and a cutting assembly; a cleaning mechanism 300, the cleaning mechanism 300 comprising a fixing seat 301, the inner wall of the fixing seat 301 being provided with an air pump 308 via a transmission assembly; Among them, the driving component includes a top plate 201, the top outer wall of the top plate 201 is fixedly connected to the cylinder A202, the bottom outer wall of the top plate 201 is fixedly connected to the cylinder B207, and the movable end of the cylinder B207 is fixedly connected to the movable plate 206; the cutting component includes a cylinder 210, the inner wall of the cylinder 210 is slidably connected to the slider 212, the outer wall of the slider 212 is fixedly connected to the cutter 214, and the inner wall of the cylinder 210 is slidably connected to the movable ring 211.

[0020] The above scheme is adopted: multiple groups of cylindrical blocks are provided on the placement plate 100, and a whole page of circular silicone keys can be placed on the placement plate 100 so that the keys correspond to the cylindrical blocks, and can be cut by the slitting mechanism 200. The cutter 214 is used to cut the silicone keys, and the cutter 214 can rotate along the circumference of the silicone keys to cut. Each group of cylinders 210 in the slitting mechanism 200 is provided with a cutter 214, which can simultaneously cut a whole page of multiple silicone keys at the same time, with high efficiency; after the cutting is completed, residual silicone scraps will remain on the placement plate 100. When the operator needs to take out the cut silicone keys, the silicone scraps will affect the removal. The silicone scraps can be blown out of the placement plate 100 by the blowing pump 308 in the cleaning mechanism 300, while the silicone keys can still remain on the placement plate 100, making it convenient for the operator to remove the silicone keys from the placement plate 100.

[0021] like Figures 1 to 4 As shown, the top plate 201 is fixedly connected to the outer wall of the fixing seat 301 , the moving rod 204 passes through the moving plate 206 and the outer wall of the cylinder 210 , and the moving plate 206 is slidably connected to the outer wall of the fixing seat 301 .

[0022] Adopting the above solution: the placing plate 100, the fixing seat 301 and the top plate 201 are all fixed, and in the initial state, Figure 1As shown, there is a certain distance between the pressing block 205 and the placement plate 100, and the entire page of silicone keys can be placed on the placement plate 100; when the cylinder A202 is started, its movable end can drive the connecting plate 203, the moving rod 204, and the pressing block 205 to move up and down synchronously. The moving rod 204 and the pressing block 205 correspond to the positions of the cylindrical blocks on the placement plate 100 and are also the same in size. When the entire page of silicone keys is placed on the placement plate 100, the moving rod 204 and the pressing block 205 can be driven downward by the cylinder A202, so that the silicone keys are pressed between the pressing block 205 and the cylindrical blocks of the placement plate 100 for fixation. At this time, the state is as follows Figure 3 As shown, when the moving rod 204 moves, the moving plate 206 is fixed by the cylinder B207 and will not move with the moving rod 204; then the cylinder B207 drives the moving plate 206 and the cutting assembly to move downward, and the silicone button can be cut. At this time, the state is as follows Figure 2 As shown, the cylinder 210 contacts the annular groove of the placement plate 100 to fix the entire silicone button, thereby preventing the silicone button from moving due to force during the slitting process, resulting in burrs on the slitting edge or uneven slitting.

[0023] like Figures 4 to 7 As shown, the cutting assembly also includes a fixed plate 216, which is fixedly connected to the outer wall of the movable ring 211. The fixed plate 216 is elastically connected to the outer wall of the bottom end of the movable plate 206 through a reset spring 218. The outer wall of the slider 212 is fixedly connected with a protrusion 213, the inner wall of the movable ring 211 is provided with an arc groove 215, and the outer wall of the fixed plate 216 is fixedly connected with a handle 217.

[0024] The above scheme is adopted: when the cylinder 210 is inserted into the annular groove of the placement plate 100, the cutter 214 contacts the silicone button on the placement plate 100, and the blade surface of the cutter 214 is arc-shaped, fitting the circumference of the silicone button; each group of cylinders 210 is provided with a movable ring 211, and multiple groups of movable rings 211 are fixed by a fixed plate 216, which passes through the outer wall of the cylinder 210 and is fixedly connected to the outer wall of the movable ring 211. The handle 217 is provided on both sides of the movable plate 206. When the operator presses down the handle 217, the fixed plate 216 and the multiple groups of movable rings 211 will be driven to move synchronously. Under normal circumstances, due to the elastic force of the return spring 218, the fixed plate 21 6 is in a certain position with the movable ring 211, the protrusion 213 on the outer wall of the slider 212 contacts the inner wall of the bottom end of the arc groove 215, and the handle 217 is pressed down to move the fixed plate 216 downward, which will cause the return spring 218 to be stretched; the arc groove 215 is opened in the inner wall of the movable ring 211 and surrounds the inner wall of the movable ring 211 in an inclined state, and its two ends are in the same vertical position; one side of the cutter 214 is an inclined surface, and the inclined surface is divided into a blade, which is relatively sharp. When the cutter 214 moves, it moves as a whole in the direction of the inclined surface to cut the silicone keypad, and the inclined surface part of the cutter 214 can move in contact with the edge of the silicone keypad, thereby avoiding the generation of burrs after cutting, and making it smoother and more complete.

[0025] like Figures 4 to 7 As shown, the cylinder 210 is fixedly connected to the outer wall of the bottom end of the movable plate 206, the protrusion 213 contacts the inner wall of the arc groove 215, the fixed plate 216 passes through the outer wall of the cylinder 210, the fixed plate 216 is slidingly connected to the inner wall of the cylinder 210, and the two ends of the return spring 218 are fixedly connected to the outer walls of the movable plate 206 and the fixed plate 216 respectively.

[0026] The above solution is adopted: when the movable ring 211 moves downward, the inner wall of the arc groove 215 will generate an extrusion force on the outer wall of the protrusion 213, causing the protrusion 213 to move. Since the slider 212 fixed with the protrusion 213 can only make a circular motion along the inner wall of the cylinder 210, the arc groove 215 will drive the protrusion 213 and the slider 212 to rotate during the downward movement of the movable ring 211, and drive the cutter 214 to move synchronously, so that the cutter 214 moves in contact with the circumferential edge of the silicone key. When the protrusion 213 moves from one end of the arc groove 215 to the other end, the cutter 214 just moves around the circumference of the silicone key, and the silicone key can be cut. At this time, the pressing block 205 and the cylinder 210 fix the silicone button, and the silicone button will not move during the cutting process due to its soft texture; since the cutting blade 214 is curved and fits the edge of the silicone button, no burrs will be generated during the cutting process, and the silicone button can be cut off more accurately, and the operator does not need to perform further cutting and removing operations on the burrs, which is more convenient; after the cutting is completed, the handle 217 can be released, and the fixed plate 216 moves up and reset under the elastic force of the reset spring 218, the movable ring 211 moves up synchronously, and the protrusion 213 moves in the opposite direction along the inner wall of the arc groove 215, driving the slider 212 and the cutter 214 to return to the initial position.

[0027] like Figure 3 、 Figures 8 to 10 As shown, the transmission assembly includes a rack 302, the inner wall of the fixed base 301 is rotatably connected to the gear 303, the outer wall of the gear 303 is fixedly connected to the synchronous wheel A304, the outer wall of the synchronous wheel A304 is connected to the synchronous wheel B306 through the synchronous belt 305, the outer wall of the synchronous wheel B306 is fixedly connected to the threaded rod 307, and the outer wall of the threaded rod 307 is provided with a bevel gear set 309.

[0028] Adopt the above scheme: after the cutting is completed, start the cylinder B207 first, the movable end of the cylinder B207 will drive the movable plate 206 to move upward, the cylinder 210 will be out of contact with the silicone scrap on the placement plate 100, the movable end of the cylinder A202 will remain fixed to the movable rod 204, and the pressing block 205 will still fix the silicone button on the placement plate 100. Figure 3 As shown; when the movable plate 206 moves upward, the two sets of blowing pumps 308 can be driven to move horizontally through the transmission assembly. The air outlet of the blowing pump 308 corresponds to the surface position of the placement plate 100, and the generated air flow can blow the silicone scraps out from the placement plate 100 so that they will not remain on the placement plate 100. Then the operator can more conveniently remove all the silicone keys from the placement plate 100, avoiding the problem that the silicone keys are cut and the scraps are on the placement plate 100. When removing them, the scraps are easily mixed with the silicone keys, and the operator needs to sort them out, which is a more cumbersome problem.

[0029] like Figure 3 、 Figures 8 to 10As shown, the fixed seat 301 is fixedly connected to the outer wall of the placement plate 100, the rack 302 is fixedly connected to the outer wall of the movable plate 206, the rack 302 is slidingly connected to the inner wall of the fixed seat 301, and the rack 302 is meshed with the gear 303; the synchronous wheel A304 and the synchronous wheel B306 are both rotatably connected to the inner wall of the fixed seat 301, and the threaded rod 307 is rotatably connected to the inner wall of the fixed seat 301; the air pump 308 is slidably connected to the inner wall of the fixed seat 301, and the outer wall of the air pump 308 is threadedly connected to the threaded rod 307; the bevel gear set 309 includes two groups of meshing bevel gears, and the threaded rod 307 is provided with two groups, and the two groups of threaded rods 307 are respectively fixedly connected to the outer walls of the two groups of bevel gears.

[0030] The above scheme is adopted: when the movable plate 206 and the rack 302 move upward, the gear 303 will be driven to rotate, and the synchronous wheel A304 on its outer wall will be driven to rotate. The synchronous wheel A304, the synchronous belt 305 and the synchronous wheel B306 are a common transmission structure. The synchronous belt 305 always maintains a certain tension, so that when the synchronous wheel A304 rotates, the synchronous wheel B306 will be driven to rotate through the movement of the synchronous belt 305; because the diameter of the synchronous wheel A304 is larger than the diameter of the synchronous wheel B306, there is a speed difference between the two. In the same time, the number of rotations of the synchronous wheel A304 is less than the number of rotations of the synchronous wheel B306, so that the synchronous wheel B306 can drive a group of threaded rods 307 fixed thereto to rotate, and the threaded rods 307 will drive the air pump 308 to move. Since the air pump 308 can only be moved in The fixing seat 301 moves laterally in the inner wall, so that the blowing pump 308 moves along the outer wall of one side of the placement plate 100, blowing air to the silicone scraps on the placement plate 100 to move it to the outside. Since the synchronous wheel B306 rotates a large number of circles, the blowing pump 308 can move from one end of the placement plate 100 to the other end; when a group of threaded rods 307 rotates, it will drive a group of bevel gears in the bevel gear set 309 to rotate, and drive another group of bevel gears meshing with it to rotate, so that the two groups of threaded rods 307 distributed at right angles rotate synchronously, and the other group of threaded rods 307 drives the corresponding blowing pump 308 to move synchronously, so that the silicone scraps can be blown from both sides of the placement plate 100 at the same time, and the silicone scraps can be blown off from the placement plate 100 more comprehensively, making it easier for the operator to remove the silicone button later.

[0031] The working principle and use process of the present invention: Place the entire sheet of circular silicone buttons on the placement plate 100, ensuring that the buttons correspond to the multiple groups of cylindrical blocks on the placement plate 100, and start the cylinder A202. Its movable end drives the connecting plate 203, the moving rod 204 and the pressing block 205 to move downward synchronously. The pressing block 205 will press the silicone buttons between it and the cylindrical blocks of the placement plate 100 to fix the silicone buttons; then start the cylinder B207, and its movable end drives the moving plate 206 and the cutting assembly to move downward. During this process, the cylinder 210 will be inserted into the annular groove of the placement plate 100 to further fix the entire sheet of silicone buttons. At the same time, the cutter 214 contacts the silicone buttons on the placement plate 100. The curved blade surface of the cutter 214 fits the circumference of the silicone buttons, and the sharp part of the bevel contacts the silicone buttons. The operator presses down the handle 217, driving the fixed plate 216 and the multiple groups of movable rings 211 to move downward synchronously, and the return spring 218 is stretched; when the movable ring 211 moves downward, the inclined arc groove 215 on its inner wall will squeeze the protrusion 213 on the outer wall of the slider 212, so that the protrusion 213 drives the slider 212 and the cutter 214 to rotate along the inner wall of the movable ring 211. When the protrusion 213 moves from one end of the arc groove 215 to the other end, the cutter 214 just moves one circle around the circumference of the silicone keypad, and the moving direction is toward the inclined surface of the cutter 214, and the silicone keypad can be attached. The edge of the silicone key is cut. After the cutting is completed, the handle 217 is released. Under the elastic force of the reset spring 218, the fixed plate 216, the movable ring 211, the slider 212 and the cutter 214 return to the initial position; the cutter 214 is used to fit the circular edge of the silicone key for rotational cutting. Compared with the existing cutting method of pressing down by the tool, the problem of silicone deformation and tearing when under pressure, and the generation of more burrs on the edge is avoided. The burrs around the silicone key after cutting can be greatly reduced, and no additional burr removal operation is required, which is more efficient.

[0032] After the cutting is completed, the cylinder B207 is started, and its movable end drives the movable plate 206 and the cutting assembly to move upward, so that the cylinder 210 is out of contact with the silicone scraps on the placement plate 100, the movable end of the cylinder A202 remains fixed, and the pressing block 205 still fixes the cut silicone buttons; when the movable plate 206 moves upward, the rack 302 on its outer wall drives the gear 303 to rotate, and then drives the synchronous wheel B306 to rotate through the synchronous wheel A304 and the synchronous belt 305, and the synchronous wheel B306 drives a group of threaded rods 307 to rotate, and the threaded rod 307 drives another group of threaded rods 307 to rotate synchronously through the bevel gear set 309. When the two groups of threaded rods 307 rotate, they will drive the corresponding blowing pumps 308 to move horizontally along both sides of the placement plate 100. The airflow generated by the blowing pump 308 blows the silicone scraps on the placement plate 100 to the outside, cleaning the residual silicone scraps. After the silicone scraps are cleaned, start the cylinder A202, and its movable end drives the moving rod 204 and the pressing block 205 to move upward, releasing the fixation of the silicone button. The operator can then easily remove the cut silicone button from the placement plate 100, avoiding the problem of the silicone button being mixed with the scraps and needing to be sorted after removal.
