Description

Technical Field

[0001] The invention relates to a push button switch, in particular to automatic assembly equipment for a push button switch. Background Art

[0002] Existing flashlights are basically switched by buttons. This button switch is specifically a multi-open and one-close thing. By opening multiple times to adjust different gears, the brightness of the flashlight can be adjusted. The existing button switch includes a button, an upper cover, a base, a spring, a dynamic conductive sheet and a static conductive sheet. By pressing the button, the dynamic conductive sheet is driven to rotate, and the static conductive sheet is connected to form a circuit conduction. Its specific structure is that the static conductive sheet is installed on the upper cover (the static conductive sheet is fixed between the upper cover and the base), the spring is fixed on the base, the button is located on the upper cover and extends out of the upper cover, the dynamic conductive sheet is linked with the button, and the upper cover and the base are matched to achieve overall fixation.

[0003] The existing push button switches are installed manually or semi-automatically, and their assembly efficiency is extremely low. The static conductive sheet is fed by the vibration of the vibration plate. Due to the small size of the static conductive sheet, it is easy to accumulate. Manual monitoring is required throughout the process to prevent jamming.

[0004] However, during the assembly process, the static conductive sheet and the button are first installed on the upper cover, and then the base is matched with the upper cover. There is a problem with this operation that the spring is easy to fall due to gravity during operation, which greatly reduces the overall installation efficiency. Therefore, these steps are assembled manually, which greatly reduces the overall efficiency. Summary of the invention

[0005] The main technical problem solved by the invention is to provide a push button switch automatic assembly device.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a push button switch automatic assembly equipment, including a push button switch, the push button switch includes a button, an upper cover, a base, a spring, a dynamic conductive sheet, an OFF conductive sheet and at least two static conductive sheets, including a conveying mechanism, an upper cover mounting mechanism, a button mounting mechanism, a static conductive sheet mounting mechanism, a dynamic conductive sheet mounting mechanism, a spring mounting mechanism, an OFF conductive sheet mounting mechanism, a base mounting mechanism and a riveting mechanism, the conveying mechanism includes a clamp and a conveyor belt, the clamp is provided with a fixing groove adapted to the upper cover, the upper cover mounting mechanism, the button mounting mechanism , a static conductive sheet installation mechanism, a dynamic conductive sheet installation mechanism, a spring installation mechanism, a base installation mechanism and a riveting mechanism are all located on both sides of the conveyor belt; the static conductive sheet installation mechanism includes a first material tray and a first stamping device, the first material tray is provided with a first material belt, the material belt is provided with static conductive sheets distributed in an array, the static conductive sheets are conveyed to the upper cover, and the first stamping device stamps the static conductive sheets and the first material belt apart; the spring installation mechanism includes a clamping device, the clamping device includes a first clamping head and a power source, the first clamping head is provided with a magnet and a first air flow channel, and the power source drives the first clamping head to absorb the base with a spring.

[0007] First of all, the overall processing efficiency is improved through the fully automated assembly equipment. The operator only needs to control the materials on each vibration plate or material plate. There is no need to stand next to the assembly equipment all the time. The monitoring is 100%. The operator can be reminded of the shortage of materials through alarms or other means. One operator can control multiple devices. In the form of a material belt, the static conductive sheet is directly fed through the material belt. Since the static conductive sheet is arranged in an array on the material belt, there is a certain gap between two adjacent static conductive sheets, which ensures that it is not easy to get stuck during the feeding process, and it is not necessary to feed through the vibration plate, which is very convenient. Through the setting of the magnet, since the spring itself is made of metal, it is easy to be adsorbed by the magnet, that is, the relationship between the three is the first clamping head, the base and the spring. Due to the effect of magnetism, it is greater than the gravity of the spring, so that the spring can be fixed on the base. With this setting, the base can be directly fixed with the upper cover, which is more convenient to install and improves production efficiency. Compared with manual installation or horizontal installation of the base and the upper cover, this structure greatly reduces the difficulty of installation and is more convenient to install.

[0008] The static conductive sheet installation mechanism includes a first positioning column, and the first material strip is provided with first positioning holes distributed in an array, and the first positioning column is fixed through the first positioning hole.

[0009] The first positioning column cooperates with the first positioning hole to achieve the positioning effect of the first material strip, ensuring that the number of static conductive sheets is limited during operation.

[0010] The static conductive sheet installation mechanism further includes a first through slot, the first material strip passes through the first through slot, a first positioning slot is arranged in the first through slot, and the first positioning hole is located above the first positioning slot.

[0011] The first through groove is transversely conductive, and the first material strip passes through the first through groove to form a fixing effect. At the same time, the first positioning groove is set so that the first positioning column passes through the first positioning hole and abuts against the first positioning groove to achieve positioning and fixing.

[0012] Among them, the clamping device also includes a second clamping head, the second clamping head is provided with a positioning column, the base is provided with a positioning hole, the positioning column is adapted to the positioning hole; the base mounting mechanism includes a base feeding device, and the front end of the base feeding device is located below the second clamping head.

[0013] The second clamping head is set up, and the second clamping head is mainly used to clamp the base, so that the efficiency of the clamping mechanism is improved. That is, while the second clamping head is clamping the base, the first clamping head has already clamped the base equipped with a spring, thereby achieving synchronous clamping and greatly improving the overall efficiency.

[0014] Among them, the spring installation mechanism includes a spring feeding device, a first fixed block, a blocking mechanism, a second fixed block and a first slider. The first fixed block is provided with a channel adapted to the spring, the second fixed block is provided with a slide, the first slider moves on the slide, and the first slider is provided with a spring accommodating hole. The spring enters the spring accommodating hole through the channel through the spring feeding device, and then the first slider is moved to the bottom of the first clamping head; the blocking mechanism is inserted into the channel to limit the movement of the spring.

[0015] The spring feeding arrangement makes the spring delivery more accurate. Specifically, when one spring moves downward, a blocking mechanism is inserted into the channel to limit the movement of the remaining springs, ensuring that only one spring falls into the first slider.

[0016] Among them, the spring installation mechanism includes a spring vibration plate and a pipeline, the output end of the spring vibration plate is connected to the pipeline, the other end of the pipeline is connected to the channel, and the pipeline is adapted to the size of the spring.

[0017] The pipeline transmission method can prevent the spring from getting entangled during the transmission process, and the spring itself has elasticity. The transmission effect of other transmission methods is worse than that of pipeline transmission.

[0018] Among them, the conveying mechanism includes a first operating device and a second operating device, the conveyor belt includes a first conveyor belt and a second conveyor belt, the first conveyor belt and the second conveyor belt are arranged in parallel, the first operating device and the second operating device are arranged oppositely and are respectively located at the two ends of the first conveyor belt, and the two transport the clamp from the first conveyor belt to the second conveyor belt or the second conveyor belt to the first conveyor belt, forming a crawler-type operation as a whole.

[0019] Through the setting of two conveyor belts, the whole fixture forms a crawler-type operation, which makes the operation more convenient, miniaturized, and does not occupy a large space. At the same time, the setting of two devices, one drives the fixture to move upward, and the other drives the fixture to move downward, realizes the operation effect more accurately and improves the overall operation efficiency.

[0020] Among them, the button includes a button outer sleeve and a button inner sleeve, the button outer sleeve and the button inner sleeve are linked, the button outer sleeve is provided with a latch tooth, and the upper cover is provided with a latch slot; the button installation mechanism is provided with a second suction device and a first rotating device, the second suction device sucks the button outer sleeve into the upper cover, and the first rotating device drives the button outer sleeve to rotate so that the button outer sleeve is connected to the upper cover.

[0021] The first rotating device is provided so that the button outer sleeve is connected and fixed to the upper cover, thereby preventing the assembly of the button inner sleeve from being affected during the assembly process.

[0022] Among them, the first rotating device includes a first rotating drive motor, a rack and a rotating shaft. One end of the first rotating drive motor is linked with the rack to drive the rack to move, and the other end of the rack is linked with the top end of the rotating shaft. The bottom end of the rotating shaft extends into the button housing to drive the button housing to rotate.

[0023] The rack is linked to the rotating shaft. The number of rotations can be adjusted by adjusting the linkage length between the rack and the rotating shaft to ensure the stability of the overall rotation.

[0024] The utility model also includes a cutting mechanism and a collecting mechanism. The cutting mechanism cuts off the waste materials on the OFF conductive sheet and the static conductive sheet, and the collecting mechanism collects the assembled push button switch.

[0025] The cutting mechanism is used to cut off the waste on the conductive sheet. Here, the waste is specifically the connection between two adjacent conductive sheets on the material strip. The setting of the collecting mechanism makes it possible for the operator to collect the material only at the end of the device after the overall assembly is completed, making the operation easier.

[0054] See attached Figure 1-28 As shown, a push button switch automatic assembly device includes a push button switch 1, a conveying mechanism 2, an upper cover mounting mechanism 3, a button mounting mechanism 4, a static conductive sheet mounting mechanism 5, a dynamic conductive sheet mounting mechanism 6, a spring mounting mechanism 7, an OFF conductive sheet mounting mechanism 8, a base mounting mechanism 9, a riveting mechanism 10, a cutting mechanism 11 and a collecting mechanism 12.

[0055] The button switch 1 includes a button 13, an upper cover 14, a base 15, a spring 16, a dynamic conductive sheet 17, an OFF conductive sheet 18, and at least two static conductive sheets 19. The static conductive sheets 19 are symmetrically arranged, that is, the two static conductive sheets 19 are connected through the two ends of the dynamic conductive sheet 17, so as to control the brightness level of the lamp. The static conductive sheets 19 are generally arranged in an even number. In this embodiment, only six static conductive sheets 19 are taken as an example. The button 13 includes a button outer sleeve 131 and a button inner sleeve 132. The button outer sleeve 131 and the button inner sleeve 132 are arranged in linkage. The button outer sleeve 131 is provided with a latching tooth 1311, and the button inner sleeve 132 is provided with a ratchet tooth 1321. The upper cover 14 is provided with a latching groove 141. The latching tooth 1311 and the ratchet tooth 1321 are both located in the latching groove 141. Then, the button 13 is pressed to drive the dynamic conductive sheet 17 linked with the button inner sleeve 132 to rotate, so as to realize the connection between the dynamic conductive sheet 17 and the static conductive sheet 19. The spring 16 is located between the dynamic conductive sheet 17 and the base 15. The base 15 is provided with a spring fixing column 161 adapted to the spring 16. The OFF conductive sheet 18 and the spring 16 are both sleeved on the spring fixing column 161. The OFF conductive sheet 18 is located below the spring 16. The OFF conductive sheet 18 and the static conductive sheet 19 are both arranged in a plane.

[0056] The conveying mechanism 2 includes a first operating device 21, a second operating device 22, a conveyor belt and a clamp 23. The conveyor belt includes a first conveyor belt 24 and a second conveyor belt 25. The first conveyor belt 24 and the second conveyor belt 25 are arranged in parallel and have the same length. The specific assembly process is assembled on the first conveyor belt 24. The second conveyor belt 25 is only used to operate the empty clamp 23. The first operating device 21 and the second operating device 22 are arranged oppositely and are respectively located at the two ends of the first conveyor belt 24. The two conveyors transport the clamp 23 from the first conveyor belt 24 to the second conveyor belt 25 or from the second conveyor belt 25 to the first conveyor belt 24, forming a crawler-type operation as a whole. Its specific structure is that the first operating device 21 is located on the left side of the first conveyor belt 24, and the second operating device 22 is located on the right side of the first conveyor belt 24. The first operating device 21 operates the clamp 23 from the first conveyor belt 24 to the second conveyor belt 25, and the second operating device 22 operates the clamp 23 from the second conveyor belt 25 to the first conveyor belt 24, forming a crawler-type operation as a whole. Here, the first operating device 21 may operate the clamp 23 from the second conveyor belt 25 to the first conveyor belt 24, and the second operating device 22 may operate the clamp 23 from the first conveyor belt 24 to the second conveyor belt 25. This embodiment only describes that the first operating device 21 operates the clamp 23 from the first conveyor belt 24 to the second conveyor belt 25, and the second operating device 22 operates the clamp 23 from the second conveyor belt 25 to the first conveyor belt 24.

[0057] The clamp 23 slides on the first conveyor belt 24 and the second conveyor belt 25. Specifically, the clamp 23 is provided with a transverse protrusion 231, and the first conveyor belt 24 and the second conveyor belt 25 are provided with a slide groove 241 adapted to the transverse protrusion 231, so that the clamp 23 slides on the conveyor belt. Further, the front end of the transverse protrusion 231 is provided with a guide surface for easy transmission.

[0058] The first operating device 21 includes a first moving block 211, a first transverse motor 212, a second slider 213 and a first longitudinal motor 214. The second operating device 22 includes a second moving block 221, a second transverse motor 222, a third slider 223 and a second longitudinal motor 224. The first moving block 211 and the second moving block 221 have the same structure. Both are provided with a groove 2111 adapted to the clamp 23. The groove 2111 is connected to the first conveyor belt 24 and the second conveyor belt 25.

[0059] The first longitudinal motor 214 drives the first movable block 211 to move up and down through the second slider 213, and the first transverse motor 212 drives the clamp 23 to move toward the second conveyor belt 25 (i.e., move to the right); the second longitudinal motor 224 drives the second movable block 221 to move up and down through the third slider 223, and the second transverse motor 222 drives the clamp 23 to move toward the first conveyor belt 24 (i.e., move to the left).

[0060] In addition, both conveyor belts are filled with clamps 23 so that the clamps 23 fit together. For example, when the clamp 23 at one end of the first conveyor belt 24 moves downward, a clamp 23 must be added at the other end of the first conveyor belt 24 to ensure that the first conveyor belt 24 and the second conveyor belt 25 are always full. With this arrangement, the whole body moves by driving force, and only one clamp 23 can be pushed out and one clamp 23 can be pushed forward at a time, ensuring the stability of the overall operation.

[0061] Furthermore, detection sensors can be provided at both ends of the two conveyor belts, and an alarm can be sounded if the clamp 23 is stuck or lacks material.

[0062] The clamp 23 is provided with a fixing groove 232 adapted to the upper cover 14 .

[0063] The upper cover installation mechanism 3 includes a first vibration plate 31, a first feeding device 32 and a first pushing mechanism 33. The upper cover 14 is vibrated by the first vibration plate 31, and the upper cover 14 is turned over and then arranged in an array to enter the first feeding device 32. The upper cover 14 is pushed to the clamp 23 of the first conveyor belt 24 by the first pushing mechanism 33. The first conveyor belt 24 is provided with a notch 242 connected to the first feeding device 32, so that the upper cover 14 moves horizontally into the clamp 23. Here, the first pushing mechanism 33 includes a first pushing motor 331 and a first push rod 332. The first pushing motor 331 pushes the first push rod 332 to move. The first push rod 332 is located at the discharge end of the first feeding device 32, and then the upper cover 14 is directly pushed into the clamp 23 through the notch 242. Here, the top of the upper cover 14 is set downward, that is, the upper cover 14 is inverted, and there is a gap between the upper cover 14 and the fixing groove 232. The height of this gap exceeds the height of the button 13, ensuring that the button 13 is suspended.

[0064] The button installation mechanism 4 includes a button outer sleeve installation mechanism and a button inner sleeve installation mechanism. The button outer sleeve 131 is installed first, and then the button inner sleeve 132 is installed. The button outer sleeve installation mechanism includes a second vibration disk 1310, a second feeding device 1312, a second suction device 1313 and a first rotating device 1314. The button outer sleeve 131 is vibrated in the second vibration disk 1310 and arranged in an array to the second feeding device 1312. A second discharge trough 1315 is provided on the discharge end of the second feeding device 1312. The second suction device 1313 puts the button outer sleeve 131 in the second discharge trough 1315 into the upper cover 14. The second suction device 1313 can be sucked by vacuum or other suction methods. Then the first rotating device 1314 drives the button cover 131 to rotate so that the button cover 131 is connected to the upper cover 14. Here, the first rotating device 1314 includes a first rotating driving motor 1316, a rack 1317 and a rotating shaft 1318. One end of the first rotating driving motor 1316 is linked with the rack 1317 to drive the rack 1317 to move. The other end of the rack 1317 is linked with the top of the rotating shaft 1318. The bottom end of the rotating shaft 1318 extends into the button cover 131 to drive the button cover 131 to rotate. The number of rotations can be adjusted by adjusting the linkage length between the rack 1317 and the rotating shaft 1318 to ensure the stability of the overall rotation.

[0065] The button inner sleeve installation mechanism includes a third vibration disk 1320, a third feeding device 1322 and a third suction device 1323. The button inner sleeve 132 is vibrated by the third vibration disk 1320 and arranged in an array to the third feeding device 1322. A third discharge trough 1324 is provided on the discharge end of the third feeding device 1322, and then sucked into the upper cover 14 through the third suction device 1323, and linked with the button outer sleeve 131.

[0066] The static conductive sheet installation mechanism 5 includes a first group of static conductive sheet installation mechanisms 51, a second group of static conductive sheet installation mechanisms 52 and a third group of static conductive sheet installation mechanisms 53. The first group of static conductive sheet installation mechanisms 51, the second group of static conductive sheet installation mechanisms 52 and the third group of static conductive sheet installation mechanisms 53 have the same overall structure, so only the first group of static conductive sheet installation mechanisms 51 is described here. The first group of static conductive sheet installation mechanisms 51 includes a first material tray 511, a second material tray 512, a fourth feeding device 513 and a first punching device 514. The first material tray 511 and the second material tray 512 are symmetrically arranged and fixed at the top of the device. The two have the same structure. The first material tray 511 is provided with a first material belt 5111, and the first material belt 5111 is provided with static conductive sheets 19 distributed in an array. The adjacent static conductive sheets 19 are provided with first positioning holes 5112, so that the first positioning holes 5112 are also distributed in an array.

[0067] The fourth feeding device 513 is provided with two feeding channels 5131, and the output ends of the two feeding channels 5131 are located on both sides of the first conveyor belt 24. The feeding channels 5131 are gradually reduced, that is, the size of the connection with the first material tray 511 is larger than the size of the output end.

[0068] The first punching device 514 is provided with a first through slot 5141, a first positioning column 5142 and a first punching piece 5143. The output end of the feeding channel 5131 is connected with the first through slot 5141, so that the first material belt 5111 extends into the first through slot 5141. The first positioning column 5142 cooperates with the first positioning hole 5112 to achieve positioning. Then, the static conductive sheet 19 is punched by the first punching piece 5143, so that the static conductive sheet 19 is separated from the material belt. After the punching is completed, the static conductive sheet 19 is directly fixed on the upper cover 14. Here, the direction of the first through slot 5141 is parallel to the first conveyor belt 24. A first positioning slot 5144 is provided in the first through slot 5141, and the first positioning hole 5112 is located above the first positioning slot 5144, so that the first positioning column 5142 passes through the first positioning hole 5112 and abuts against the first positioning slot 5144 to achieve positioning and fixing. At this time, the two material belts work simultaneously, that is, the two static conductive sheets 19 are fixed on the upper cover 14 , that is, the two static conductive sheets 19 are partially located on both sides of the first conveyor belt 24 .

[0069] For the overall layout, the first group of static conductive sheet installation mechanisms 51 and the second group of static conductive sheet installation mechanisms 52 are symmetrically arranged. The second group of static conductive sheet installation mechanisms 52 also fixes two static conductive sheets 19 on the upper cover 14, that is, four static conductive sheets 19 are partially located on both sides of the first conveyor belt 24. The structure and assembly process here are the same as those of the first group of static conductive sheet installation mechanisms 51.

[0070] The third set of static conductive sheet installation mechanism 53 is on one side of the first conveyor belt 24. The third set of static conductive sheets 19 is usually also two static conductive sheets 19. The third set of static conductive sheet installation mechanism 53 also fixes two static conductive sheets 19 on the upper cover 14. However, the difference from the other two sets of static conductive sheet installation mechanisms 5 is that the static conductive sheets 19 here are installed on the other two sides of the upper cover 14, specifically on the fixture 23 after stamping, that is, vertically arranged with the other static conductive sheets 19. The static conductive sheets 19 are specifically placed on the upper cover 14 by suction through the first suction device 515. It should be noted here that the installation order of the three sets of static conductive sheets 19 can be adjusted at will and set according to actual needs. If two-on and one-off settings are required, the installation of one set of static conductive sheets 19 can be omitted.

[0071] The moving conductive sheet installation mechanism 6 includes a fourth vibration disk 61, a fifth feeding device 62, a positioning bracket 63 and a fourth suction device 64. The moving conductive sheet 17 is vibrated by the fourth vibration disk 61 and arranged in an array into the fifth feeding device 62, and is transmitted by the fifth feeding device 62. A positioning bracket 63 is installed on the first conveyor belt 24, and a moving conductive sheet positioning hole 631 is provided on the positioning bracket 63. When the clamp 23 is running, the moving conductive sheet positioning hole 631 and the upper cover 14 are arranged as coaxial axes to ensure that the moving conductive sheet 17 is installed in a directional manner. Specifically, at this time, a boss adapted to the moving conductive sheet 17 is provided in the moving conductive sheet positioning hole 631. The fourth suction device 64 sucks the moving conductive sheet 17, and places the moving conductive sheet 17 into the upper cover 14 through the moving conductive sheet positioning hole 631 for fixing, so that the moving conductive sheet 17 is linked with the button sleeve 131.

[0072] The OFF conductive sheet installation mechanism 8 is similar in structure to the static conductive sheet installation mechanism 5 . Both are transmitted through a material tray and then cut by punching. The difference is that the static conductive sheet 19 is directly installed on the upper cover 14 , and the OFF conductive sheet 18 is placed on the base mounting seat 93 .

[0073] The base mounting mechanism 9 includes a fifth vibration disk 91, a sixth feeding device 92 and a base mounting seat 93. The base 15 is vibrated by the fifth vibration disk 91, fed by the sixth feeding device 92, and then sucked by the second clamping head and placed on the base mounting seat 93. Since the OFF conductive sheet 18 is already on the base mounting seat 93, the OFF conductive sheet 18 is connected to the base 15 at this time.

[0074] The spring installation mechanism 7 includes a spring vibration disk 71, a clamping device 72, a spring feeding device 73, a blocking mechanism 74 and a spring detection device. The spring 16 is fed by the vibration of the spring vibration disk 71. The output end of the spring vibration disk 71 is connected to the pipe 76, and the other end of the pipe 76 is connected to the channel. The pipe 76 is adapted to the size of the spring 16, so that the spring 16 is arranged in sequence in the pipe 76. Here, the pipe 76 can specifically be made of transparent material, and the operator can intuitively observe the state inside the pipe 76.

[0075] The clamping device 72 includes a first clamping head 721 and a second clamping head 722. The first clamping head 721 is used to clamp the base 15 equipped with the spring 16 and the OFF conductive sheet 18, and then cooperate with the upper cover 14 to fix it. The second clamping head 722 is used to clamp the base 15 and place it on the base mounting seat 93. That is, the clamping device 72 forms left and right movements through the driving mechanism to achieve synchronous operation and improve the clamping effect. For example, when the second clamping head 722 clamps the base 15, the first clamping head 721 has already clamped the base 15 equipped with the spring 16 and the OFF conductive sheet 18, and placed the base 15 above the spring 16 by moving. The first clamping head 721 cooperates and fixes the base 15 equipped with the spring 16 with the upper cover 14. The setting of this structure greatly improves the overall assembly efficiency.

[0076] A magnet fixing groove 7211 is provided in the first clamping head 721, and the magnet fixing groove 7211 is used to install a magnet 7212. The size of the magnet 7212 can be adjusted according to the thickness of the base 15, that is, the magnet 7212 can absorb the spring 16 through the base 15. The first clamping head 721 has a clamping groove 7213 adapted to the base 15, so that during the clamping process, the base 15 is partially embedded in the clamping groove 7213, forming a stable clamping, preventing the base 15 from rotating during the clamping process, which affects the actual assembly effect.

[0077] The second clamping head 722 is provided with a positioning head 7221 , and the base 15 is provided with a positioning through hole 151 . The positioning head 7221 is adapted to the positioning through hole 151 . The second clamping head 722 absorbs the base 15 through the cooperation between the positioning head 7221 and the positioning through hole 151 .

[0078] Here, the clamping device 72 realizes clamping by an air pump, specifically a vacuum air pump. The first clamping head 721 is provided with a first air flow channel 7214, and the second clamping head 722 is provided with a second air flow channel 7222. Vacuum suction is formed through the air flow channel to improve the efficiency of clamping.

[0079] The spring feeding device 73 feeds the material by vibrating the spring vibrating plate 71 , and finally feeds the material through a pipe 76 adapted to the spring 16 , ensuring that the springs 16 are arranged in the pipe 76 one by one.

[0080] It also includes a first fixed block 771, a second fixed block 772 and a first slider 773. The first fixed block 771 is provided with a channel 7711 adapted to the spring 16, the second fixed block 772 is provided with a slideway 7721, the first slider 773 moves on the slideway 7721, and the first slider 773 is provided with a spring accommodating hole 7731. The spring 16 enters the spring accommodating hole 7731 through the spring feeding device 73 through the channel 7711, and then the first slider 773 is moved to the bottom of the first clamping head 721, where the first slider 773 is directly driven by a driving motor to achieve a sliding effect.

[0081] The blocking mechanism 74 includes a pin 741 and a servo motor 742. The servo motor 742 is linked with the pin 741 to control the pin 741 to move forward and backward and up and down. The pin 741 moves forward and backward and is inserted into the channel 7711 to limit the movement of the remaining springs 16. Since the springs 16 are set in gaps, compared with other blocking members, the pin 741 is not easy to squeeze and deform the springs 16 during the blocking process. After the pin 741 is inserted into the channel 7711, it moves upward, so that the fallen spring 16 is completely separated from the spring 16 in the pipe 76, preventing multiple springs 16 from affecting the actual assembly during use.

[0082] The first fixed block 771 is provided with a detection hole 7712, which is connected to the channel 7711. The spring detection device detects the state in the channel 7711 through the detection hole 7712. The detection hole 7712 is specifically a top portion of the first fixed block 771 that extends obliquely into the channel 7711, and the connection between the detection hole 7712 and the channel 7711 is located at the position where the pin 741 is inserted. The spring detection device can detect whether there is a spring 16 in the channel 7711 by using an infrared sensor or other detection device.

[0083] The spring driving module includes a pin 7713 , which moves the spring 16 upward through a motor or other driving device, so that the spring 16 is connected and fixed to the base 15 . Specifically, the spring 16 is sleeved on the top of the pin 7713 to achieve movement.

[0084] The riveting mechanism 10 includes a riveting head 101 . After the base 15 and the upper cover 14 are assembled, the base 15 and the upper cover 14 are directly riveted and fixed by the riveting head 101 .

[0085] The conductive sheet detection mechanism includes a detection head 102. The detection head 102 detects the number of conductive sheets and transmits the detected number of conductive sheets to the control mechanism, which determines whether the analysis is qualified.

[0086] The cutting mechanism 11 includes a first cutting mechanism 111, a second cutting mechanism 112 and a third cutting mechanism 113. The first cutting mechanism 111 includes a cutting fixed block 1111 and a first cutting head 1112. The cutting fixed block 1111 separates the OFF conductive sheet 18 and the static conductive sheet 19 located on the same side, that is, the fixed block part extends between the OFF conductive sheet 18 and the static conductive sheet 19. A punching hole 1113 is provided on the cutting fixed block 1111, and then the first cutting head 1112 passes through the punching hole 1113 to form a cut OFF conductive sheet 18.

[0087] The second cutting mechanism 112 is used to cut part of the static conductive sheets 19 located on the first conveyor belt 24, and the cutting is also performed by punching. Here, the second cutting mechanism 112 directly cuts off the waste of part of the static conductive sheets 19 located on both sides of the first conveyor belt 24, that is, four static conductive sheets 19.

[0088] The third cutting mechanism 113 needs to cut the static conductive sheet 19 located on the fixture 23. Specifically, the third cutting mechanism 113 includes a third push rod 1131 and a third cutting head 1132. The third cutting head 1132 is located on the side of the first conveyor belt 24. The third push rod 1131 is provided with a fixing cavity 1133 adapted to the button switch 1. The third push rod 1131 directly pushes the installed button switch 1 in the fixture 23 to the bottom of the third cutting head 1132, and directly cuts off the waste material. Here, two static conductive sheets 19 are cut off. It should be noted here that the waste material is specifically the connector on the material belt for connecting the conductive sheets to each other.

[0089] The order of the three cutting mechanisms 11 can be adjusted, and the operator can adjust it according to the number of static conductive sheets 19 actually required.

[0090] It also includes a waste collection mechanism 121. The bottoms of the three cutting heads are all connected to the waste collection mechanism 121 to collect waste in a unified manner.

[0091] The collecting mechanism 12 includes a qualified product collecting mechanism 122 and a failed product collecting mechanism 123. The qualified product collecting mechanism 122 includes a fourth push rod 1221, and the failed product collecting mechanism 123 includes a fifth push rod 1231. The control mechanism controls the movement of the fourth push rod 1221 or the fifth push rod 1231 to push the cut button switch 1 into a suitable area for collection.

[0092] All the overall mechanisms are controlled by the control mechanism, and the control mechanism is PLC control. The operator can adjust the PLC program according to actual needs to realize the assembly of different button switches 1.

[0093] First, the overall processing efficiency is improved through the fully automated assembly equipment. The operator only needs to control the materials on each vibration plate or material plate, and does not need to stand next to the assembly equipment all the time. The monitoring is 100%, and the operator can be reminded of the shortage of materials through alarms or other means. One operator can control multiple devices. In the form of a material belt, the static conductive sheet 19 is directly fed through the material belt. Since the static conductive sheet 19 is arranged in an array on the material belt, there is a certain gap between two adjacent static conductive sheets 19, which ensures that it is not easy to get stuck during the feeding process, and it is not necessary to feed through the vibration plate, which is very convenient. Through the setting of the magnet 7212, since the spring 16 itself is made of metal, it is easy to be adsorbed by the magnet 7212, that is, the relationship between the three is the first clamping head 721, the base 15 and the spring 16. Due to the effect of magnetism, it is greater than the gravity of the spring 16, so that the spring 16 can be fixed on the base 15. With this setting, the base 15 can be directly fixed with the upper cover 14, which is more convenient to install and improves production efficiency. Compared with manual installation or horizontal installation of the base 15 and the upper cover 14, this structure greatly reduces the difficulty of installation and is more convenient for installation.
