Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, and in particular to an automatic switch assembly machine. Background Technology

[0002] A micro switch is a switch with a small contact gap and a quick-acting mechanism. It operates with a specified stroke and force, and is enclosed in a housing with an external actuator. It is named a micro switch because of its small contact gap. Micro switches are widely used in electronic equipment, instruments, mining, power systems, household appliances, electrical equipment, and military fields such as aerospace, aviation, and shipbuilding. A micro switch generally consists of a housing, a push button, a clip, a spring, terminals, and a base. When assembling such a micro switch, the housing, push button, and clip are first assembled to form the housing assembly. Then, the terminals and base are welded together to form the base assembly. Finally, the housing assembly, spring, and base assembly are assembled.

[0003] However, in existing technologies, the assembly of the housing assembly, spring, and base assembly is done manually or by equipment. Manual assembly suffers from low efficiency, high labor intensity, and high labor costs. Equipment assembly requires first loading the housing assembly and conveying it to the spring loading area, then vertically assembling the spring within the housing assembly. After assembly, the housing assembly and spring are conveyed to the base assembly loading area, where the base assembly and housing assembly are then closed and assembled. However, during the conveying of the housing assembly with the spring, the lack of support for the vertically assembled spring makes it prone to tipping over, leading to an increase in defective products and inconsistent assembly quality with a low pass rate. Therefore, there is an urgent need to design a new automatic switch assembly device. Summary of the Invention

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please see Figure 1 , Figure 2 and Figure 19 An automatic switch assembly machine includes a rotary disk 100, a housing feeding mechanism 200, a spring feeding mechanism 300, a base feeding mechanism 400, and a sorting and unloading mechanism 500. A plurality of fixtures 110 are spaced apart on the rotary disk 100. The housing feeding mechanism 200, spring feeding mechanism 300, base feeding mechanism 400, and sorting and unloading mechanism 500 are sequentially arranged around the rotary disk 100 along the assembly direction. A fixed disk 120 is arranged above the rotary disk 100, and a toggle mechanism 600 and a dust collector are arranged on the fixed disk 120. The assembly includes a 700 mechanism and a detection mechanism 800. Multiple sets of actuation mechanisms 600 are provided, each corresponding to a housing feeding mechanism 200, a base feeding mechanism 400, and a sorting and unloading mechanism 500. A dust removal mechanism 700 is located between the housing feeding mechanism 200 and the spring feeding mechanism 300 along the assembly direction. Detection mechanisms 800 are provided between the spring feeding mechanism 300 and the base feeding mechanism 400, between the base feeding mechanism 400 and the sorting and unloading mechanism 500, and between the sorting and unloading mechanism 500 and the housing feeding mechanism 200.

[0022] Specifically, in this embodiment, during the assembly of the switch, the housing feeding mechanism 200 automatically feeds the housing into the fixture 110 of the rotary disk 100. After the housing is fed, the rotary disk 100 rotates with the fixture 110 until it reaches the spring feeding mechanism 300, which automatically feeds the spring into the fixture 110 for assembly with the housing. After the spring and housing are assembled, the rotary disk 100 then drives the fixture 110 to rotate to the base for feeding. At mechanism 400, the base is automatically fed by the base feeding mechanism 400, and the base is assembled with the plastic shell in the fixture 110. After the plastic shell, spring and base are assembled, the rotary disk 100 continues to drive the fixture 110 to the sorting and unloading mechanism 500. The sorting and unloading mechanism 500 automatically sorts the assembled switch products, and finally completes the automated assembly of the switch. This reduces manual operation, lowers labor costs and improves the assembly efficiency of the switch, while also ensuring the assembly quality.

[0023] Additionally, when loading the plastic housing, the corresponding actuating mechanism 600 acts on the fixture 110 to open it, allowing the plastic housing to be loaded into the fixture 110. Similarly, when loading the base, the corresponding actuating mechanism 600 acts on the fixture 110 to open it, facilitating the loading of the base and assembly with the plastic housing in the fixture 110. Furthermore, during sorting and unloading, the corresponding actuating mechanism 600 opens the fixture 110 to facilitate the sorting and unloading mechanism 500 to unload the plastic housing from the fixture 110. The assembled switches are sorted. However, when loading springs, there is no need to open the fixture 110. The springs can be directly loaded into the fixture 110 and assembled with the housing. When the rotary disk 100 drives the fixture 110 to rotate and transport the housing and springs, the fixture 110 can support the springs, so the springs will not tip over during the rotation and transport process. This facilitates the subsequent assembly of the base, ensures the assembly quality of the switches, improves the product qualification rate, and makes the overall structural design of the assembly machine reasonable.

[0024] Meanwhile, after the plastic housing is automatically fed, the rotary table 100 drives the fixture 110 to move the plastic housing to the dust removal mechanism 700, where the dust removal mechanism 700 removes dust from the inside of the plastic housing to ensure the assembly quality of the subsequent switches. After the spring and plastic housing are assembled, they are inspected by the corresponding detection mechanism 800. Similarly, after the base is assembled, the corresponding detection mechanism 800 will inspect it again to ensure the assembly quality of the switches. Finally, the detection mechanism 800 between the sorting and unloading mechanism 500 and the plastic housing feeding mechanism 200 checks whether there are any products missing from the fixture 110 to ensure normal assembly in the future, thus making the structural design of the assembly machine reasonable. The dust removal mechanism 700 can use air blowing for dust removal, and the detection mechanism 800 uses photoelectric detection, both of which are existing technologies, so they will not be described in detail here.

[0025] Please see Figure 3 and Figure 4 In order to achieve normal feeding of the plastic shell and base, and to support the spring during the rotation and conveying process, the fixture 110 in this embodiment includes two sets of oppositely arranged support plates 111. One end of the support plate 111 abuts against the fixture 110 through an elastic element 112, wherein the elastic element 112 is a compression spring. The other end of the support plate 111 has a semi-circular groove, and a toggle block 113 is provided on the top of the support plate 111. The toggle mechanism 600 includes a toggle cylinder 610 and a toggle fork 620. The toggle fork 620 is connected to the toggle cylinder 610. The toggle cylinder 610 drives the toggle fork 620 to move, and the toggle fork 620 acts on the toggle block 113 on the top of the support plate 111, thereby opening the two sets of oppositely arranged support plates 111.

[0026] When automatically feeding the housing and base, and sorting and unloading the assembled switches, the actuating cylinder 610 of the actuating mechanism 600 drives the shift fork 620 to move towards the fixture 110. During the movement, the shift fork 620 acts on the actuating blocks 113 on the top of the two sets of support plates 111, causing the two sets of support plates 111 to open outward. This causes the support plates 111 to press against the elastic element 112, thereby opening the two sets of support plates 111. At this time, the housing and base can be fed, and the assembled switches can be sorted and unloaded. The switch is used for unloading; when the spring is being loaded, the two sets of support plates 111 close under the use of the elastic element 112, and the semi-circular grooves at opposite ends will surround to form a circular hole, and the diameter of the circular hole formed by the surround will be slightly larger than the diameter of the spring. The spring can be directly loaded into the fixture 110 and assembled with the plastic shell through the circular hole. When the rotating disk 100 drives the fixture 110 to rotate and transport the plastic shell and the spring, the spring can be supported through the circular hole. Therefore, the spring will not tip over during the rotation and transport process, so as to ensure the subsequent assembly quality.

[0027] Please see Figure 5 and Figure 8 Because the plastic shell (plastic shell, buttons, and clips have been assembled) needs to be inspected during loading and glued for subsequent bonding and assembly with the base, the plastic shell loading mechanism 200 in this embodiment includes a plastic shell feeding channel 210, a conveying unit 220, a transfer unit 230, a CCD detection unit 240, a glue dispensing unit 250, a plastic shell conveying channel 260, a plastic shell misalignment plate 270, and a plastic shell moving module 280. The transfer unit 230, the CCD detection unit 240, and the glue dispensing unit 250 are sequentially arranged in the plastic shell feeding channel 210 and the plastic shell conveying channel 260. Between channels 260, and the transfer unit 230 is located at the end of the plastic shell receiving channel 210. A push unit 290 is provided at the beginning of the plastic shell conveying channel 260. The plastic shell misalignment plate 270 is located at the end of the plastic shell conveying channel 260 and is provided with a plastic shell misalignment groove 271. The conveying unit 220 travels back and forth between the transfer unit 230, the CCD detection unit 240, the dispensing unit 250 and the push unit 290. The plastic shell moving module 280 has a plastic shell suction nozzle 281. The plastic shell moving module 280 drives the plastic shell suction nozzle 281 to travel back and forth between the plastic shell misalignment groove 271 and the fixture 110.

[0028] During automatic feeding of plastic shells, a vibratory feeder vibrates the shells into the incoming material channel 210. The shells are then conveyed sequentially within the material channel 210 and transported to the transfer unit 230. The handling unit 220 then picks up the shells from the transfer unit 230 and places them into the CCD detection unit 240. The CCD detection unit 240 checks whether the fed shells are qualified. After the detection is completed, the handling unit 220 picks up the shells from the CCD detection unit 240 and places them into the dispensing unit 250, where the dispensing unit 250 automatically dispenses glue. Once the dispensing is complete, the handling unit... Yuan 220 again picks up the glue shell from the dispensing unit 250 and places it into the pushing unit 290. The pushing unit 290 pushes the glue shell sequentially into the glue shell conveying channel 260. The glue shell in the glue shell conveying channel 260 is then conveyed into the glue shell misalignment groove 271 of the glue shell misalignment plate 270. The glue shell misalignment plate 270 then misaligns the glue shell. After misalignment, the glue shell moving module 280 drives the glue shell suction nozzle 281 to pick up the glue shell in the glue shell misalignment groove 271 and place it into the fixture 110 to complete the automated feeding of the glue shell, thereby reducing manual operation, reducing labor costs, and improving subsequent assembly efficiency.

[0029] Please see Figures 9 to 11To achieve transfer, CCD inspection, and dispensing of the plastic shell, the transfer unit 230 includes a transfer table 231, a transfer lifting cylinder 232, and a transfer lifting plate 233. The transfer table 231 has a transfer groove 234, which connects to the tail end of the plastic shell feeding channel 210. The transfer lifting cylinder 232 is located below the transfer table 231, and the transfer lifting plate 233 is located in the transfer groove 234 and connected to the transfer lifting cylinder 232. The transfer lifting cylinder 232 can drive the transfer lifting plate 233 to move up and down within the transfer groove 234. The CCD inspection unit 240 includes an inspection stand 241, an inspection platform 242, and an inspection camera 243. The inspection camera 243 is located in... On the inspection stand 241, an inspection platform 242 is located on one side of the inspection stand 241, and an inspection rotary cylinder 244 is installed on the inspection platform 242. The inspection rotary cylinder 244 is connected to an inspection rotary seat 245, which is located below the inspection camera 243. The inspection rotary cylinder 244 can drive the inspection rotary seat 245 to rotate. The dispensing unit 250 includes a dispensing stand 251, a dispensing seat 252, and a dispensing cylinder 253. The dispensing seat 252 is located at the lower part of the dispensing stand 251, and the dispensing cylinder 254 is installed at the upper part of the dispensing stand 251. The dispensing cylinder 253 is connected to the dispensing cylinder 254, and the dispensing cylinder 254 can drive the dispensing cylinder 253 to move closer to or away from the dispensing seat 252.

[0030] Specifically, the plastic shells are sequentially conveyed in the plastic shell inlet channel 210 and then conveyed to the transfer groove 234 of the transfer table 231, so that the plastic shells are placed on top of the transfer lifting plate 233. At this time, the transfer lifting cylinder 232 drives the transfer lifting plate 233 to rise upward. After being lifted to the set position, the conveying unit 220 will clamp the plastic shells on top of the transfer lifting plate 233 and place them on the detection rotating seat 245 in the CCD detection unit 240. The detection rotating cylinder 244 will then drive the detection rotating seat 245 to rotate, and the detection camera 243 will be activated. The system takes pictures of the plastic shells on the rotating inspection seat 245 to check their quality and ensure the quality of subsequent assembly. After the inspection is completed, the transport unit 220 will pick up the plastic shells from the rotating inspection seat 245 and place them on the dispensing seat 252. The dispensing cylinder 254 will drive the dispensing cylinder 253 to move towards the dispensing seat 252. After moving to the set position, the dispensing cylinder 253 will dispense glue to the corresponding position of the plastic shell. Finally, the automatic transfer, automatic inspection and automatic dispensing of the plastic shells are realized to reduce manual operation and improve assembly efficiency.

[0031] Please see Figure 12In order to realize the handling of the plastic shell, the handling unit 220 in this embodiment includes a handling fixed base 221, a handling lifting plate 222 and a handling moving plate 223. The handling lifting plate 222 is movably disposed on the handling fixed base 221 and is connected to a handling lifting cylinder 224. The handling lifting cylinder 224 can drive the handling lifting plate 222 to move longitudinally along the handling fixed base 221. The handling moving plate 223 is movably disposed on the handling lifting plate 222 and is connected to a handling cylinder 225. The handling cylinder 225 can drive the handling moving plate 223 to move laterally along the handling lifting plate 222. A handling gripper cylinder 226 is provided on the handling moving plate 223.

[0032] During transport, the transport lifting cylinder 224 drives the transport lifting plate 222 to rise and fall, and the transport moving plate 223 is driven by the transport cylinder 225 to move laterally, thereby moving the transport gripper cylinder 226 laterally and longitudinally. The transport gripper cylinder 226 then transports the plastic shell sequentially from the transfer unit 230 to the CCD detection unit 240, then from the CCD detection unit 240 to the dispensing unit 250, and finally from the dispensing unit 250 to the pushing unit 290, thus realizing automatic transport of the plastic shell. The transport moving plate 223 is equipped with three sets of transport gripper cylinders 226. By using the three sets of transport grippers 226 to transport the plastic shell in sequence, the transport efficiency of the plastic shell can be improved, thereby improving the assembly efficiency of the switch.

[0033] Please see Figure 13 In order to transport the plastic shells in the plastic shell conveying channel 260, the pushing unit 290 in this embodiment includes a pushing bracket 291, a pushing seat 292, a pushing plate 293, and a receiving box 294. The receiving box 294 is located on one side of the pushing bracket 291, and the pushing seat 292 is movably mounted on the pushing bracket 291 and connected to a pushing cylinder 295. The pushing cylinder 295 can drive the pushing seat 292 to move above the receiving box 294 and connect with the first end of the plastic shell conveying channel 290. The pushing seat 292 has a pushing groove 296, and a pushing cylinder 297 is provided on the pushing seat 296. The pushing plate 293 is connected to the pushing cylinder 297, and the pushing cylinder 297 drives the pushing plate 296 to move along the pushing groove 296.

[0034] When the glue shell is moved from the dispensing unit 250 to the pushing unit 290, the conveying unit 220 moves the glue shell into the pushing groove 296 of the pushing seat 292. At this time, the pushing cylinder 297 drives the pushing plate 293 to move. When the pushing plate 293 moves, it pushes the glue shell in the pushing groove 296 into the glue shell conveying channel 260, so that the glue shells in the glue shell conveying channel 290 are conveyed sequentially. If the glue shell is detected as unqualified at the CCD detection unit 240, the pushing cylinder 295 drives the pushing seat 292 to move forward. The pusher 292 moves backward, separating from the plastic shell conveying channel 260 and moving above the receiving box 294. The handling unit 220 then directly drops the unqualified plastic shells into the receiving box 294. If the plastic shell is qualified, the pusher cylinder 295 drives the pusher 292 to move, connecting with the first end of the plastic shell conveying channel 260 and moving above the receiving box 294. The handling unit 220 then transports and places the plastic shell into the pusher groove 296 of the pusher 292, thus achieving automatic conveying of the plastic shells in this cycle.

[0035] Please see Figure 14 and Figure 15 After the plastic shell is loaded onto the fixture 110, the rotary disk 100 drives the fixture 110 to rotate and transport the plastic shell to the spring loading mechanism 300, where the spring loading mechanism 300 automatically loads and assembles the springs. Therefore, in this embodiment, the spring loading mechanism 300 includes a spring conveying channel 310, a spring loading unit 320, and a spring assembly unit 330. The spring loading unit 320 is located at the end of the spring conveying channel 310, and the spring assembly unit 330 is mounted on the fixed disk 120. The spring loading unit 320 includes a spring loading bracket 321, a spring rotating cylinder 322, and a spring rotating seat 323. The spring rotating cylinder 322 is mounted on the spring loading bracket 321, and the spring rotating seat 323 is connected to the spring rotating cylinder 322. The spring rotating cylinder 322 can drive the spring to rotate. The seat 323 rotates, and a stepped through hole 324 is provided on the spring rotating seat 323; the spring assembly unit 330 includes a spring transverse cylinder 331, a spring longitudinal cylinder 332, an assembly seat 333, and a spring assembly cylinder 334. The spring longitudinal cylinder 332 is connected to the spring transverse cylinder 331, and the spring transverse cylinder 331 can drive the spring longitudinal cylinder 332 to move laterally. The assembly seat 333 is installed on the spring longitudinal cylinder 332, and the spring longitudinal cylinder 332 can drive the assembly seat 333 to move longitudinally. The assembly seat 333 is provided with an assembly cylinder 335. The spring assembly cylinder 334 is set on the assembly seat 333 and is connected to an assembly pin 336. The assembly pin 336 is inserted into the assembly cylinder 335, and the spring assembly cylinder 334 can drive the assembly pin 336 to move within the assembly cylinder 335.

[0036] Specifically, during the spring loading and assembly process, the spring vibratory feeder vibrates the springs into the spring conveying channel 310. The springs are then conveyed sequentially in the spring conveying channel 310 and delivered to the stepped through hole 324 of the spring rotating seat 323. The springs are placed within the stepped through hole 324 and are limited by the step of the stepped through hole 324. At this time, the spring rotating cylinder 322 drives the spring rotating seat 323 to rotate 90°, so that the stepped through hole 324 faces upward. The spring transverse cylinder 331 drives the assembly seat 333 to move above the stepped through hole 324, and the spring longitudinal cylinder 332 drives the assembly seat 333 to move downward. After moving to the set position, the spring assembly cylinder 334 drives the assembly pin 336 to insert into the stepped through hole 324, and the spring is interference-fitted onto the assembly seat. The assembly needle 336 is loaded onto the assembly needle 336. Then, the spring longitudinal movement cylinder 332 and the spring transverse movement cylinder 331 drive the assembly seat 333 to move to the fixture 110, and the assembly needle 336 and the spring extend from the semi-circular grooves of the two sets of support plates 111 into the fixture 110 and are assembled with the rubber shell in the fixture 110. At this time, the assembly needle 336 is driven to move upward by the spring assembly cylinder 334. When the assembly needle 336 moves upward, the bottom end of the assembly cylinder 335 limits the spring to prevent the spring from moving with the assembly needle 336. When the assembly needle 336 is fully retracted into the assembly cylinder 335, the spring is disengaged from the assembly needle 336 and assembled in the rubber shell. At the same time, the two sets of support plates 111 of the fixture 110 support the spring, and finally realize the automated assembly of the spring to improve the assembly effect.

[0037] Please see Figure 16 and Figure 17 In this embodiment, in order to realize the automatic feeding and assembly of the base, the base feeding mechanism 400 includes a base conveying channel 410, a base misalignment plate 420 and a base moving module 430. The base misalignment plate 420 is set at the conveying end of the base conveying channel 410 and has a base misalignment groove 421. The base moving module 430 has a base gripper cylinder 431. The base moving module 430 drives the base gripper cylinder 431 to move back and forth between the base misalignment groove 421 and the fixture 110. The base is vibrated by the base vibrating plate and sent to the base conveying channel 410. The base is then conveyed sequentially in the base conveying channel 410 and sent to the base misalignment groove 421 of the base misalignment plate 420. At this time, the base misalignment plate 420 is misaligned, and the base moving module 430 drives the base gripper cylinder 431 to move. The base gripper cylinder 431 grips the base in the base misalignment groove 421 and then places the gripped base into the fixture 110 to assemble with the plastic shell, thereby completing the automated assembly of the plastic shell, spring and base.

[0038] Finally, please see Figure 18After the switch is assembled, it needs to be automatically unloaded. Therefore, the sorting and unloading mechanism 500 in this embodiment includes an unloading moving module 510, a sorting box 520, a sorting plate 530, and a sorting rotary cylinder 540. The sorting plate 530 is set in the sorting box 520 and connected to the sorting rotary cylinder 540. The sorting rotary cylinder 540 can drive the sorting plate 530 to swing, so that the sorting box 520 forms a good product channel and a defective product channel. The unloading moving module 510 has an unloading gripper cylinder 511. The unloading moving module 510 drives the unloading gripper cylinder 511 to move back and forth above the fixture 110 and the sorting box 520.

[0039] When the preceding inspection mechanism 800 detects that the assembled switch is a good product, the sorting rotary cylinder 540 drives the sorting plate 520 to swing, closing the defective product channel and opening the good product channel. Meanwhile, the unloading moving module 510 drives the unloading claw cylinder 511 to grip the assembled switch in the fixture 110 and drop the gripped switch into the good product channel of the sorting box 520 for collection. When the preceding inspection mechanism 500 detects that the assembled switch is a defective product, the sorting rotary cylinder 540 drives the sorting plate 530 to swing again, closing the good product channel and opening the defective product channel. The unloading moving module 510 then drives the unloading claw cylinder 511 to drop the gripped switch into the defective product channel of the sorting box 520 for collection. This achieves the sorting and collection of good and defective products, making the structural design of the sorting and unloading mechanism 500 reasonable, reducing manual operation, and improving the assembly efficiency of the switch.

[0040] In addition, the shell moving module 280, the base moving module 430, and the unloading moving module 510 in this embodiment are all two-axis moving modules (horizontal and vertical) and are existing technologies, so they will not be described in detail here.
