Description

Technical Field

[0001] This invention belongs to the field of electronic equipment technology, specifically a batch cleaning device for Mylar sheets used in silicone push-button switches. Background Technology

[0002] In the field of electronic devices, silicone push-button switches, with their stable rebound force, provide operators with excellent tactile feedback and are widely used in various electronic devices. Their working principle utilizes the properties of silicone buttons, mounted on circuit boards such as PCBs or FPCs to achieve switching functions. In the production process of silicone push-button switches, Mylar sheets play a crucial role. During production, silicone keys are first batch-bonded onto a full sheet of Mylar sheets, and then die-cut to form individual silicone push-button switches. In this process, the Mylar sheets not only serve to support the silicone keys, but their cleanliness directly affects the subsequent bonding effect of the silicone keys and the quality of the final product. Therefore, cleaning the entire sheet of Mylar sheets before bonding the silicone keys is a critical step in ensuring product quality.

[0015] Preferably, the filtration mechanism includes a filter plate, a mounting base, and a first limiting rod. The filter plate is slidably connected inside the cleaning box. The mounting base is fixed to the outside of the filter plate, and the first limiting rod is fixed to the outside of the mounting base. A first limiting plate is fixed to one end of the first limiting rod, and a second limiting plate is slidably connected to the outside of the first limiting rod. A second limiting rod is slidably connected inside the cleaning box, and a return spring is sleeved on the outside of the second limiting rod. A limiting block is fixed to one end of the second limiting rod. Several sets of filter holes are opened on the surface of the filter plate. The return spring is used to squeeze the second limiting rod and the limiting block and keep them moving inward.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the combination of a support plate, a support frame, and other structures, enables the device to place Mylar sheets with silicone buttons on them, allowing them to be immersed in the cleaning solution inside the cleaning box by flipping them over. The reciprocating motion enhances the immersion and cleaning effect of the Mylar sheets with silicone buttons, thereby achieving the goal of improving the cleaning efficiency of the device for Mylar sheets with silicone buttons.

[0017] This invention, through the coordination of a bidirectional motor, motor linkage, and a first gear, enables the device to move the first and second limiting plates in opposite directions by activating the bidirectional motor. This, in turn, limits the position of the Mylar sheet with the silicone button attached, ensuring it is securely positioned within the first and second cleaning racks. Consequently, the position of the Mylar sheet does not shift during reciprocating motion in soaking and cleaning, thus achieving the goal of improving the cleaning effect of the Mylar sheet.

[0018] This invention, through the coordinated arrangement of connecting rods, transmission wheels, and a delivery pump, enables the device to draw in cleaning liquid through a first delivery pipe by activating the delivery pump. The suction force of the first delivery pipe drives the transmission wheel to rotate, thereby turbulenting the cleaning liquid inside the cleaning box and improving the soaking effect of the Mylar tablets. The suction force of the first delivery pipe drives the transmission wheel to rotate, further turbulenting the cleaning liquid inside the cleaning box and improving the soaking effect of the Mylar tablets. The delivery pump then delivers the cleaning liquid through a second delivery pipe to a third delivery pipe and a nozzle, which sprays it onto the surface of the Mylar tablets for cleaning. This achieves the goal of improving the soaking and cleaning effect of the Mylar tablets.

[0019] This invention, through the coordinated arrangement of a filter plate, mounting base, and first limiting rod, enables the device to move the second limiting plate towards the limiting block by pressing the filter plate, thereby squeezing the limiting block and causing it to retract inward. After the second limiting plate passes the limiting block, a return spring resets the limiting block, and the limiting block lifts the second limiting plate, causing the second and first limiting plates to fit together. At this point, pulling the filter plate allows it to be removed for cleaning or replacement. After cleaning, pressing it again allows for quick installation. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 11 As shown, the present invention provides a batch cleaning device for Mylar film for silicone button switches, including a cleaning box 1, a flipping mechanism 2 installed inside the cleaning box 1, a limiting mechanism 3 installed at the top of the flipping mechanism 2, a cleaning mechanism 4 fixed outside the cleaning box 1, a top plate 5 fixed at the top of the cleaning box 1, and a filtering mechanism 6 installed inside the cleaning box 1.

[0024] like Figures 1 to 6As shown, the flipping mechanism 2 includes a support plate 201, a servo motor 202, and a support frame 203. The support plate 201 is fixed inside the cleaning box 1, and the servo motor 202 is fixed outside the support plate 201. The rotating end of the servo motor 202 is fixed to the support frame 203. The rotating end of the rotating end of the servo motor 203 is fixed to a forward and reverse intermittent motor 204. A first pulley 205 is fixed to the rotating end of the forward and reverse intermittent motor 204. A meshing belt 206 is sleeved on the outside of the first pulley 205. A first cleaning frame 207 is fixed to one end of the meshing belt 206. A second pulley 208 is rotatably connected inside the support frame 203. A second cleaning frame 209 is fixed to one end of the meshing belt 206. A meshing belt 206 is sleeved on the outside of the second pulley 208. Two sets of servo motors 202 are provided. The servo motors 202 are symmetrically distributed about the central axis of the support plate 201. The first pulley 205 and the second pulley 208 are symmetrically distributed about the central axis of the support frame 203.

[0025] The above solution is adopted as follows: The cleaning box 1 is filled with cleaning fluid, and Mylar sheets with silicone buttons are placed in a row inside the first cleaning rack 207. The Mylar sheets are then fixed in place by the first limiting plate 306 and the second limiting plate 307. After filling the internal space of the first cleaning rack 207, the servo motor 202 is started, causing the servo motor 202 to drive the support frame 203 to rotate, thereby flipping the first cleaning rack 207 and the second cleaning rack 209. This allows the Mylar sheets fixed on the first cleaning rack 207 to be immersed in the cleaning fluid inside the cleaning box 1. At this time, Mylar sheets can be filled into the flipped second cleaning rack 209 and fixed in place. After the Mylar sheets inside the first cleaning rack 207 are soaked, the servo motor 202 is started again. 02. Flip the support frame 203 to reset the first cleaning frame 207 and the second cleaning frame 209, so that the first cleaning frame 207 is on top and the second cleaning frame 209 is immersed in the cleaning solution. The cleaning solution is sprayed downward through the nozzle 407 at the top to clean the Mylar sheets inside the first cleaning frame 207. At this time, the forward and reverse intermittent motor 204 is started. The forward and reverse intermittent motor 204 drives the first pulley 205 to rotate back and forth, and then drives the meshing belt 206 to move back and forth, so that the first cleaning frame 207 moves back and forth from left to right on the support frame 203. This allows the Mylar sheets inside the first cleaning frame 207 to effectively contact the cleaning solution sprayed from the top, thereby improving the cleaning effect.

[0026] like Figures 1 to 8As shown, the limiting mechanism 3 includes a bidirectional motor 301, a motor connecting rod 302, and a first gear 303. The bidirectional motor 301 is fixed to the outside of the first cleaning frame 207. The rotating end of the bidirectional motor 301 is fixed with the motor connecting rod 302. There are two sets of bidirectional motors 301, which are symmetrically distributed about the central axis of the first cleaning frame 207. There are also two sets of motor connecting rods 302, which are symmetrically distributed about the central axis of the bidirectional motors 301. The motor connecting rods 302 and the first cleaning frame 207 are rotatably connected.

[0027] like Figures 1 to 8 As shown, a first gear 303 is fixed to the outside of the motor connecting rod 302. A bidirectional screw 304 is rotatably connected inside the first cleaning frame 207. A second gear 305 is fixed to the outside of the bidirectional screw 304. The outer wall of the first gear 303 is provided with several sets of teeth. The outer wall of the second gear 305 is provided with several sets of teeth. The first gear 303 and the second gear 305 are meshed together. A first limiting plate 306 is threaded to the outside of the bidirectional screw 304. A second limiting plate 307 is threaded to the inside of the bidirectional screw 304. A guide rod 308 is fixed inside the first cleaning frame 207. Several sets of through holes are provided on the surfaces of the first limiting plate 306 and the second limiting plate 307. The first limiting plate 306 and the second limiting plate 307 are symmetrically distributed about the central axis of the bidirectional screw 304.

[0028] The above solution involves placing the Mylar film into the first cleaning rack 207 or the second cleaning rack 209 and then starting the bidirectional motor 301. This causes the bidirectional motor 301 to drive the motor connecting rod 302 and the first gear 303 to rotate. The shape of the first gear 303, when rotating, drives the second gear 305 to rotate, which in turn drives the bidirectional screw 304 to rotate. The rotation of the bidirectional screw 304 causes the first limiting plate 306 and the second limiting plate 307 to move in opposite directions outside the bidirectional screw 304. This movement of the first limiting plate 306 and the second limiting plate 307 clamps and limits the Mylar film inside the first cleaning rack 207. The guide rod 308 guides the first limiting plate 306 and the second limiting plate 307 to prevent them from shifting position.

[0029] like Figure 1 , Figure 2 and Figure 9As shown, the cleaning mechanism 4 includes a connecting rod 401, a transmission wheel 402, and a delivery pump 403. The connecting rod 401 is movably connected inside the cleaning box 1, and the transmission wheel 402 is fixed to the outside of the connecting rod 401. The delivery pump 403 is fixed to the outside of the cleaning box 1. The input end of the delivery pump 403 is connected to a first delivery pipe 404, and the top end of the delivery pump 403 is connected to a second delivery pipe 405. One end of the second delivery pipe 405 is connected to a third delivery pipe 406. The connecting rod 401 is rotatably connected inside the cleaning box 1. The transmission wheel 402 is provided with several sets of blades. The input end of the first delivery pipe 404 is connected to the cleaning box 1. The third delivery pipe 406 is provided with three sets, and the third delivery pipes 406 are interconnected.

[0030] like Figure 1 , Figure 2 and Figure 9 As shown, a nozzle 407 is fixed at the bottom of the third delivery pipe 406, and a solenoid valve 408 is installed at one end of the third delivery pipe 406. A guide plate 409 is connected to the input end of the first delivery pipe 404. Several groups of nozzles 407 are provided, and the nozzles 407 are distributed at equal intervals about the central axis of the third delivery pipe 406. Four groups of solenoid valves 408 are provided, and the solenoid valves 408 are arranged between each group of the third delivery pipes 406.

[0031] The above solution is as follows: When the soaked Mylar tablets need to be cleaned, the delivery pump 403 is started, causing the first delivery pipe 404 to draw in the cleaning solution. The suction force of the first delivery pipe 404 drives the drive wheel 402 to rotate. The width of the guide plate 409 can expand the suction range of the first delivery pipe 404, thereby ensuring the rotation effect of the drive wheel 402. This turbulence of the cleaning solution inside the cleaning box 1 improves the soaking effect of the Mylar tablets. The cleaning solution is then delivered by the delivery pump 403 through the second delivery pipe 405 to the third delivery pipe 406 and the nozzle 407, and finally sprayed onto the Mylar tablets through the nozzle 407. The surface of the sheet is cleaned by opening and closing multiple sets of solenoid valves 408 in different numbers, allowing the device to control the spraying range. When the two sets of solenoid valves 408 on the left are closed, the cleaning liquid will be discharged through the middle and right third delivery pipes 406 and nozzles 407. When the two sets of solenoid valves 408 on the right are closed, the cleaning liquid will be discharged through the middle and left third delivery pipes 406 and nozzles 407, and will reciprocate through the Mylar sheet, which can improve the cleaning efficiency of the Mylar sheet. The reciprocating motion of the Mylar sheet soaking in the cleaning box 1 can also improve the soaking efficiency of the Mylar sheet, thereby shortening the soaking time of the Mylar sheet.

[0032] like Figure 1 , Figure 2 and Figure 11As shown, the filtration mechanism 6 includes a filter plate 601, a mounting base 602, and a first limiting rod 603. The filter plate 601 is slidably connected inside the cleaning box 1. The mounting base 602 is fixed to the outside of the filter plate 601. The first limiting rod 603 is fixed to the outside of the mounting base 602. A first limiting plate 604 is fixed to one end of the first limiting rod 603. A second limiting plate 605 is slidably connected to the outside of the first limiting rod 603. A second limiting rod 606 is slidably connected inside the cleaning box 1. A return spring 607 is sleeved on the outside of the second limiting rod 606. A limiting block 608 is fixed to one end of the second limiting rod 606. Several sets of filter holes are opened on the surface of the filter plate 601. The return spring 607 is used to squeeze the second limiting rod 606 and the limiting block 608 and keep them moving inward.

[0033] Using the above method: By pressing the filter plate 601, the second limiting plate 605 moves towards the limiting block 608 and squeezes the limiting block 608, causing the limiting block 608 to retract inward. After the second limiting plate 605 passes the limiting block 608, the return spring 607 resets the limiting block 608, and the limiting block 608 lifts the second limiting plate 605, causing the second limiting plate 605 and the first limiting plate 604 to fit together. At this point, pulling the filter plate 601 can remove the filter plate 601, thus allowing it to be removed. After cleaning or replacement, insert the filter plate 601 into the cleaning box 1 and continue pressing the filter plate 601. This causes the first limiting plate 604 to move toward the limiting block 608 and squeeze the limiting block 608, causing the limiting block 608 to retract inward. After the first limiting plate 604 passes the limiting block 608, the return spring 607 resets the limiting block 608. At this time, the first limiting plate 604 is limited by the limiting block 608, which in turn limits the filter plate 601 and allows it to be quickly removed.

[0034] Working principle and usage process of this invention: First, after placing the Mylar film into the first cleaning rack 207 or the second cleaning rack 209, the bidirectional motor 301 is started, causing the bidirectional motor 301 to drive the motor connecting rod 302 and the first gear 303 to rotate. Then, due to the shape of the first gear 303, the rotation of the first gear 303 drives the second gear 305 to rotate, so that the second gear 305 synchronously drives the bidirectional screw 304 to rotate. Then, the rotation of the bidirectional screw 304 causes the first limiting plate 306 and the second limiting plate 307 to move in opposite directions outside the bidirectional screw 304. Then, the movement of the first limiting plate 306 and the second limiting plate 307 clamps and limits the Mylar film inside the first cleaning rack 207.

[0035] Next, the cleaning box 1 is filled with cleaning fluid, and the Mylar sheets with silicone buttons are placed in a row inside the first cleaning rack 207. The Mylar sheets are then fixed in place by the first limiting plate 306 and the second limiting plate 307. After filling the internal space of the first cleaning rack 207, the servo motor 202 is started, causing the servo motor 202 to drive the support frame 203 to rotate, thereby flipping the first cleaning rack 207 and the second cleaning rack 209. This allows the Mylar sheets fixed on the first cleaning rack 207 to be immersed in the cleaning fluid inside the cleaning box 1. At this time, Mylar sheets can be filled into the flipped second cleaning rack 209 and fixed in place. After the Mylar sheets inside the first cleaning rack 207 are soaked, the servo motor 202 is started again to flip the rack. Rotate the support frame 203 to reset the first cleaning frame 207 and the second cleaning frame 209, so that the first cleaning frame 207 is on top and the second cleaning frame 209 is immersed in the cleaning solution. The cleaning solution is sprayed downward through the nozzle 407 at the top to clean the Mylar sheets inside the first cleaning frame 207. At this time, the forward and reverse intermittent motor 204 is started, which drives the first pulley 205 to rotate back and forth. In turn, the first pulley 205 drives the meshing belt 206 to move back and forth, so that the first cleaning frame 207 moves back and forth from left to right on the support frame 203. This allows the Mylar sheets inside the first cleaning frame 207 to effectively contact the cleaning solution sprayed from the top, thereby improving the cleaning effect.

[0036] Furthermore, the guide rod 308 guides the first limiting plate 306 and the second limiting plate 307, preventing them from shifting position. When the soaked Mylar tablets need cleaning, the delivery pump 403 is activated, causing the first delivery pipe 404 to draw in cleaning fluid. The suction of the first delivery pipe 404 drives the transmission wheel 402 to rotate, thus turbulent the cleaning fluid inside the cleaning box 1, resulting in better soaking of the Mylar tablets. The delivery pump 403 then delivers the cleaning fluid through the second delivery pipe 405 to the third delivery pipe 406 and the nozzle 407, and the cleaning fluid is then delivered through the nozzle... The cleaning solution is sprayed onto the surface of the Mylar tablets for cleaning. Multiple sets of solenoid valves 408 are opened and closed in varying numbers, allowing the device to control the spraying range. When the two sets of solenoid valves 408 on the left are closed, the cleaning solution is discharged through the middle and right third delivery pipes 406 and the nozzle 407. When the two sets of solenoid valves 408 on the right are closed, the cleaning solution is discharged through the middle and left third delivery pipes 406 and the nozzle 407, and reciprocates through the Mylar tablets. This improves the cleaning efficiency of the Mylar tablets. Furthermore, the reciprocating motion of the Mylar tablets immersed in the cleaning box 1 also improves the soaking efficiency, thereby shortening the soaking time.

[0037] Finally, by placing the filter plate 601 below the cleaning liquid spray area, the cleaning liquid comes into contact with the holes in the filter plate 601, filtering out Mylar flakes impurities mixed in the cleaning liquid, thus ensuring the cleaning effect. After long-term use of the filter plate 601, if too many Mylar flakes impurities are filtered out, pressing the filter plate 601 causes the second limiting disc 605 to move towards the limiting block 608, squeezing the limiting block 608 and causing it to retract inward. After the second limiting disc 605 passes the limiting block 608, the return spring 607 resets the limiting block 608, and the limiting block 608 lifts the second limiting disc 605, making... The second limiting plate 605 and the first limiting plate 604 are in contact. At this time, the filter plate 601 can be removed by pulling it, and then it can be cleaned or replaced. After cleaning, the filter plate 601 is inserted into the cleaning box 1. The filter plate 601 is pressed, causing the first limiting plate 604 to move towards the limiting block 608 and squeeze the limiting block 608, causing the limiting block 608 to retract inward. After the first limiting plate 604 passes the limiting block 608, the return spring 607 resets the limiting block 608. At this time, the first limiting plate 604 is limited by the limiting block 608, thereby limiting the filter plate 601 and allowing it to be quickly removed.
