Description

Technical Field

[0001] The invention belongs to the technical field of electronic equipment, and in particular relates to a device for batch cleaning Mylar sheets for silicone key switches. Background Art

[0002] In the field of electronic devices, silicone key switches, with their stable rebound force, provide operators with high-quality tactile feedback and are widely used in various electronic devices. Their working principle is to utilize the characteristics of silicone keys and realize the switch function by installing them on circuit boards such as PCBs or FPCs. In the production process of silicone key switches, Mylar plays a key role. During production, silicone keys must first be laminated in batches on a full sheet of Mylar, and then punched to form individual silicone key switches. During this process, the Mylar not only serves as a carrier for the silicone keys, but its own cleanliness also directly affects the subsequent lamination of the silicone keys and the quality of the final product. Therefore, cleaning the entire sheet of Mylar before laminating the silicone keys is a key step in ensuring product quality.

[0003] Publication number CN114192487A discloses an automatic cleaning device for Mylar sheets, comprising a base plate; a supporting transverse plate arranged on the base plate, a horizontal guide rail arranged on the supporting transverse plate, a supporting vertical plate installed on the horizontal guide rail via a horizontal slider, a lifting guide rail arranged on the supporting vertical plate, and a hanging plate installed on the lifting guide rail via a lifting slider, the hanging plate being driven up and down by a lifting cylinder installed on the supporting vertical plate in cooperation with a lifting screw; a servo motor and a transmission seat for driving the horizontal slider to slide horizontally along the horizontal guide rail are provided at the horizontal end of the supporting transverse plate; the device also comprises a hydrophobic trough and a circulation barrel arranged on the base plate, the hydrophobic trough and the circulation barrel being connected via a circulation pipeline and the circulation of the hydrophobic agent being realized by the circulation motor, which can realize the automatic lifting and timed soaking of the basket containing the Mylar sheets in the hydrophobic trough, effectively improving the cleaning quality of the Mylar sheets and reducing labor costs.

[0004] However, when the device is used to clean the silicone key switch Mylar sheets, it can only soak a single set of silicone key switch Mylar sheets, resulting in reduced cleaning efficiency of the silicone key switch Mylar sheets, and the device cannot clean another set of silicone key switch Mylar sheets while soaking the silicone key switch Mylar sheets.

[0028] The above scheme is adopted: by placing the Mylar sheet into the first cleaning rack 207 or the second cleaning rack 209 and then starting the bidirectional motor 301, the bidirectional motor 301 drives the motor connecting rod 302 and the first gear 303 to rotate, and then through the shape of the first gear 303, the second gear 305 is driven to rotate when the first gear 303 rotates, so that the second gear 305 synchronously drives the bidirectional screw 304 to rotate, and then through the rotation of the bidirectional screw 304, the first limit plate 306 and the second limit plate 307 are moved in opposite directions outside the bidirectional screw 304, and then through the movement of the first limit plate 306 and the second limit plate 307, the Mylar sheet inside the first cleaning rack 207 is clamped and limited, and the guide rod 308 can guide the first limit plate 306 and the second limit plate 307 to avoid the displacement of the moving positions of the first limit plate 306 and the second limit plate 307.

[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 to the inside of the cleaning box 1, and the transmission wheel 402 is fixed to the outside of the connecting rod 401.

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

[0031] The above solution is adopted: when the soaked Mylar sheet needs to be cleaned, the delivery pump 403 is started, so that the first delivery pipe 404 absorbs the cleaning liquid, and the suction force of the first delivery pipe 404 drives the transmission wheel 402 to rotate, and the width of the guide plate 409 can expand the suction range of the first delivery pipe 404 to ensure the rotation effect of the transmission wheel 402, thereby disturbing the cleaning liquid inside the cleaning box 1, so that the Mylar sheet soaked in the cleaning box 1 has a better soaking effect, and the cleaning liquid is delivered to the third delivery pipe 406 and the nozzle 407 through the delivery pump 403 through the second delivery pipe 405, and is sprayed to the Mylar sheet through the nozzle 407. The surface of the sheet is cleaned by opening and closing different numbers of electromagnetic valves 408, so that the device can control the range of spraying. When the two sets of electromagnetic valves 408 on the left are closed, the cleaning liquid will be discharged through the third delivery pipe 406 in the middle and on the right, and the nozzle 407. When the two sets of electromagnetic valves 408 on the right are closed, the cleaning liquid will be discharged through the third delivery pipe 406 in the middle and on the left, and the nozzle 407, and reciprocate through the Mylar sheet, so that the device can improve the cleaning efficiency of the Mylar sheet, and can also improve the immersion efficiency of the Mylar sheet when the Mylar sheet immersed in the cleaning box 1 reciprocates, thereby shortening the immersion time of the Mylar sheet.

[0032] like Figure 1 、 Figure 2 and Figure 11As shown, the filtering mechanism 6 includes a filter plate 601, a mounting seat 602 and a first limiting rod 603. The filter plate 601 is slidably connected to the inside of the cleaning box 1. The mounting seat 602 is fixed to the outside of the filter plate 601. The first limiting rod 603 is fixed to the outside of the mounting seat 602. One end of the first limiting rod 603 is fixed to the first limiting disk 604. The outside of the first limiting rod 603 is slidably connected to the second limiting disk 605. The inside of the cleaning box 1 is slidably connected to the second limiting rod 606. The outside of the second limiting rod 606 is provided with a return spring 607. One end of the second limiting rod 606 is fixed to the limiting block 608. Several groups of filter holes are provided 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] The above solution is adopted: by pressing the filter plate 601, the second limiting plate 605 moves toward the limiting block 608, and the limiting block 608 is squeezed to make the limiting block 608 shrink inward, and 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, so that the second limiting plate 605 and the first limiting plate 604 are in contact. At this time, the filter plate 601 can be pulled to remove the filter plate 601, and then it can be removed. For cleaning or replacement, after cleaning is completed, insert the filter plate 601 into the cleaning box 1, continue to press the filter plate 601, so that the first limit plate 604 moves toward the limit block 608, and squeeze the limit block 608, so that the limit block 608 shrinks inward, and after the first limit plate 604 passes the limit block 608, the reset spring 607 resets the limit block 608. At this time, the first limit plate 604 is limited by the limit block 608, and then the filter plate 601 is limited, and it can be quickly disassembled.

[0034] The working principle and use process of the present invention: First, place the Mylar sheet into the first cleaning rack 207 or the second cleaning rack 209 and then start the bidirectional motor 301, so that the bidirectional motor 301 drives the motor connecting rod 302 and the first gear 303 to rotate, and then through the shape of the first gear 303, it drives the second gear 305 to rotate when the first gear 303 rotates, so that the second gear 305 synchronously drives the bidirectional screw 304 to rotate, and then through the rotation of the bidirectional screw 304, the first limit plate 306 and the second limit plate 307 move in opposite directions outside the bidirectional screw 304, and then through the movement of the first limit plate 306 and the second limit plate 307, the Mylar sheet inside the first cleaning rack 207 is clamped and limited.

[0035] Secondly, by filling the interior of the cleaning box 1 with cleaning liquid, and placing the Mylar sheets with silicone buttons in a row into the interior of the first cleaning rack 207, and fixing the Mylar sheets by the first limit plate 306 and the second limit plate 307, after completing the filling of the interior space of the first cleaning rack 207, start the servo motor 202, so that the servo motor 202 drives the support frame 203 to rotate, and then flip the first cleaning rack 207 and the second cleaning rack 209, so that the Mylar sheets fixed on the first cleaning rack 207 are immersed in the cleaning liquid inside the cleaning box 1. At this time, the Mylar sheets can be filled into the flipped second cleaning rack 209 and fixed. After completing the soaking of the Mylar sheets inside the first cleaning rack 207, continue to start the servo motor 202 to flip The support frame 203 is rotated, and the first cleaning frame 207 and the second cleaning frame 209 are reset, so that the first cleaning frame 207 is located at the top, and the second cleaning frame 209 is immersed in the cleaning liquid, and the cleaning liquid is sprayed downward through the nozzle 407 at the top to clean the Mylar sheet inside the first cleaning frame 207. At this time, the forward and reverse intermittent motor 204 is started, and the first pulley 205 is driven to rotate back and forth by the forward and reverse intermittent motor 204, and then the meshing belt 206 is driven to move back and forth by the first pulley 205, so that the first cleaning frame 207 moves back and forth from left to right on the support frame 203, so that the Mylar sheet inside the first cleaning frame 207 can effectively contact with the cleaning liquid sprayed from the top, thereby improving the cleaning effect.

[0036] In addition, the first limit plate 306 and the second limit plate 307 can be guided by the guide rod 308 to avoid the displacement of the first limit plate 306 and the second limit plate 307. When the soaked Mylar sheet needs to be cleaned, the delivery pump 403 is started to make the first delivery pipe 404 absorb the cleaning liquid, and the suction force of the first delivery pipe 404 drives the transmission wheel 402 to rotate, thereby disturbing the cleaning liquid inside the cleaning box 1, so that the Mylar sheet soaked in the cleaning box 1 has a better soaking effect, and the cleaning liquid is delivered to the third delivery pipe 406 and the nozzle 407 through the second delivery pipe 405 by the delivery pump 403, and then the cleaning liquid is delivered to the nozzle 407 through the nozzle 407 is sprayed onto the surface of the Mylar sheet to clean it, and different numbers of opening and closing are performed by multiple sets of solenoid valves 408, so that the device can control the range of spraying. When the two sets of solenoid valves 408 on the left are closed, the cleaning liquid will be discharged through the third delivery pipes 406 in the middle and on the right, and the nozzles 407. When the two sets of solenoid valves 408 on the right are closed, the cleaning liquid will be discharged through the third delivery pipes 406 in the middle and on the left, and the nozzles 407, and reciprocate through the Mylar sheet, so that the device can improve the cleaning efficiency of the Mylar sheet, and can also improve the immersion efficiency of the Mylar sheet when the Mylar sheet immersed in the cleaning box 1 reciprocates, thereby shortening the immersion time of the Mylar sheet.

[0037] Finally, by setting the filter plate 601 below the spraying point of the cleaning liquid, the cleaning liquid contacts the holes opened in the filter plate 601 and can filter out the Mylar impurities mixed in the cleaning liquid, thereby ensuring the cleaning effect. After the filter plate 601 has been put into use for a long time, when there are too many Mylar impurities filtered, the filter plate 601 is pressed to move the second limit plate 605 toward the limit block 608 and squeeze the limit block 608 so that the limit block 608 contracts inwardly. After the second limit plate 605 passes the limit block 608, the reset spring 607 resets the limit block 608, and the limit block 608 lifts the second limit plate 605, so that The second limiting plate 605 and the first limiting plate 604 are fitted together. At this time, the filter plate 601 can be removed by pulling the filter plate 601, and then it can be cleaned or replaced. After cleaning, the filter plate 601 is inserted into the cleaning box 1, and the filter plate 601 is continued to be pressed to make the first limiting plate 604 move toward the limiting block 608 and squeeze the limiting block 608 to make the limiting block 608 shrink inward. After the first limiting plate 604 passes the limiting block 608, the reset spring 607 resets the limiting block 608. At this time, the first limiting plate 604 is limited by the limiting block 608, and then the filter plate 601 is limited, so that it can be quickly removed.
