Description

Technical Field

[0001] This invention relates to the field of wall switch manufacturing technology, and more particularly to a wall switch production line. Background Technology

[0002] Wall switches, as an important component of home electrical control, are widely used in homes, offices, and industrial facilities. With the diversification of user needs, the functions of wall switches have become increasingly diverse, including single-pole single-control, single-pole double-control, double-pole single-control, and double-pole double-control switches.

[0003] Traditional wall switch production equipment can usually only assemble a single model of product, making it difficult to adapt to the production of multiple models. When changing the product model, it is necessary to shut down the machine for a long time to replace part of the production line structure, which seriously affects production efficiency. In addition, traditional production equipment often uses vibratory feeders to feed the stationary contact components. During the operation of the vibratory feeder, the stationary contact components are prone to impact, causing some parts to separate or be lost, which in turn affects the assembly quality and production stability.

[0004] Therefore, there is an urgent need for a wall switch production line to solve the above problems. Summary of the Invention

[0095] Example 1

[0096] Wall switches, as an important component of home electrical control, are widely used in homes, offices, and industrial facilities to control the on / off operation of electrical equipment, such as... Figure 1 and Figure 2 As shown, existing wall switches typically include a base 1, a stationary contact assembly 2, a moving contact assembly 3, and a panel. The stationary contact assembly 2 and the moving contact assembly 3 are disposed within the base 1, and the panel is mounted on the base 1. A button 41 on the panel can move the moving contact assembly 3 to make the stationary contact assembly 2 conduct or disconnect, thereby turning the electrical equipment on or off.

[0097] With the diversification of user needs, the functions of wall switches are becoming increasingly diverse. Based on their functions, wall switches can be divided into four types: single-pole single-control switch, single-pole double-control switch, double-pole single-control switch, and double-pole double-control switch. Different models of wall switches have the same external dimensions; the main difference lies in the number of copper components that constitute the stationary contact assembly 2 inside the switch. For example... Figure 1 As shown, the stationary contact assembly 2 in a single-pole single-control switch includes a stationary contact 21, a conductive element 22, and a single-control moving contact assembly. The single-control moving contact assembly enables the conductive element 22 to be connected or disconnected from the stationary contact 21; as shown... Figure 2 As shown, the conductive components in a double-pole double-throw switch include four stationary contacts 21, two conductive elements 22, and two double-control moving contact assemblies. Each conductive element 22 can make two opposing stationary contacts 21 connect or disconnect through a double-control moving contact assembly. The number of stationary contacts 21, moving contact assemblies 3, and conductive elements 22 in the conductive components of a single-pole double-throw switch and a double-pole single-throw switch can be selected according to the required functions. Furthermore, the specific circuit connection relationships of the above four types of wall switches are existing technology and will not be elaborated further.

[0098] Because the composition of the stationary contact assembly 2 differs in different types of wall switches, some production lines need to be redesigned and reinstalled when changing production types, resulting in high costs and impacting production efficiency.

[0099] Therefore, this embodiment provides a wall switch production line that is compatible with the assembly of four types of wall switches, such as... Figure 3 As shown, the wall switch production line includes a conveying unit 100, a base loading unit 200, and a conductive component assembly unit 300. The conveying unit 100 is used to convey the base 1. The base loading unit 200 and the conductive component assembly unit 300 are located beside the conveying unit 100. Along the conveying direction of the conveying unit 100, the conductive component assembly unit 300 is located downstream of the base loading unit 200. The base loading unit 200 can transport the base 1 of different models of wall switches onto the conveying unit 100. The conductive component assembly unit 300 includes a stationary contact assembly loading mechanism 310 and a moving contact loading mechanism 340. The stationary contact assembly... The feeding mechanism 310 includes a mold box 321, a mold conveying line 320, and a first assembly component 330. The mold box 321 is provided with a limiting groove 3211, which can carry the stationary contact component 2. The mold conveying line 320 is used to convey the mold box 321 to the first assembly component 330. The conveying unit 100 is used to convey the base 1 to the first assembly component 330. The first assembly component 330 is used to grab the stationary contact component 2 in the limiting groove 3211 and assemble the stationary contact component 2 onto the base 1. The moving contact feeding mechanism 340 is used to assemble the moving contact component 3 onto the base 1 that has the stationary contact component 2 assembled on it.

[0100] By working together, the base loading unit 200, the conveying unit 100, and the conductive component assembly unit 300 can assemble various types of wall switches, improving the compatibility of the production line, significantly reducing manual operations, and increasing production efficiency. Furthermore, by conveying the stationary contact assembly 2 that matches the base 1 through the mold box 321, the integrity of the stationary contact assembly 2 can be guaranteed, improving the quality of the assembled product.

[0101] It should be noted that the wall switch production line provided in this embodiment can be compatible with the assembly of different models of wall switches. However, in actual production, the factory will usually only produce one model of wall switch for a period of time according to order demand and production plan. By concentrating the production of orders of the same model, this production method can minimize the number and frequency of switching of the wall switch production line and improve the efficiency of the production line.

[0102] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the stationary contact assembly 2 flows through the mold box 321. The method of loading the mold box 321 onto the mold conveyor line 320 is the same as the method of loading the base onto the conveyor unit 100, and will not be described in detail here. It should be noted that the number of stationary contact assemblies 2 in a single mold box 321 is related to the number of stationary contact assemblies 2 required in a single switch product, and there are four combination methods; for example, one mold can accommodate the stationary contact assemblies 2 required for 4 sets of single-pole single-control switches, or the stationary contact assemblies 2 required for 4 sets of single-pole double-control switches, or the stationary contact assemblies 2 required for 4 sets of double-pole single-control switches, or the stationary contact assemblies 2 required for 2 sets of double-pole double-control switches. By accommodating multiple sets of stationary contact assemblies 2 in one mold box 321, the quantity of materials loaded at one time can be increased, and the assembly efficiency can be improved.

[0103] Optionally, the stationary contact assembly 2 includes a stationary contact 21 and a conductive element 22, such as... Figure 5 As shown, the limiting groove 3211 inside the mold box includes a first limiting groove 32111 and a second limiting groove 32112. The first limiting groove 32111 can limit the stationary contact 21, and the second limiting groove 32112 can limit the conductive component 22, thus ensuring the integrity of the stationary contact assembly 2 before it is transported to the first assembly assembly 330. Figure 6 and Figure 8As shown, the first assembly assembly 330 includes a first mold positioning assembly 331, a stationary contact picking robot 332, a second mold positioning assembly 333, and a conductive component picking robot 334. The first mold positioning assembly 331 is used to position the mold box 321 on the mold conveying line 320 for the first time. The stationary contact picking robot 332 can take out the stationary contact in the mold box 321 after the first positioning and assemble it onto the base 1. Along the conveying direction of the mold conveying line 320, the second mold positioning assembly 333 is located downstream of the first mold positioning assembly 331. The second mold positioning assembly 333 is used to position the mold box 321 on the mold conveying line 320 for the second time. The conductive component picking robot 334 can take out the conductive component 22 in the mold box 321 after the second positioning and assemble it onto the base 1. The stationary contact picking robot 332 and the conductive component picking robot 334 respectively take out the stationary contact 21 and the conductive component 22 from the mold box 321 and accurately assemble them onto the base 1, reducing manual operation and improving assembly efficiency and accuracy.

[0104] Optionally, such as Figure 6 The first mold positioning assembly 331 includes a first cylinder 3311, a first positioning block 3312, a second cylinder 3313, and a second positioning block 3314. The first cylinder 3311 and the second cylinder 3313 are spaced apart along the conveying direction of the mold conveying line 320. The first positioning block 3312 is connected to the piston rod of the first cylinder 3311, and the second positioning block 3314 is connected to the piston rod of the second cylinder 3313. The first cylinder 3311 drives the first positioning block 3312 along a direction perpendicular to the mold conveying line. The second cylinder 3313 drives the second positioning block 3314 to move in a direction perpendicular to the die conveying line 320, so that the first positioning block 3312 and the second positioning block 3314 form a first limiting space on the die conveying line 320, and the die box 321 is limited in the first limiting space, thereby positioning the die box 321 on the die conveying line 320 for the first time. Then, the stationary contact picking robot 332 takes out the stationary contact 21 in the die box 321 and assembles it on the base 1.

[0105] Optionally, such as Figure 6As shown, the second mold positioning assembly 333 includes a third cylinder 3331 and a third positioning block 3332. The third positioning block 3332 is connected to the piston rod of the third cylinder 3331. The driving direction of the third cylinder 3331 is at a certain angle to the conveying direction of the mold conveying line 320. When the mold box 321 moves to the second mold positioning assembly 333 along with the mold conveying line 320, the third cylinder 3331 drives the third positioning block 3332 to abut against one of the top corners of the mold box 321, applying a thrust to the mold box 321, so that the left end of the mold box 321 abuts against the end of the mold conveying line 320, and the mold and rear end abut against the side wall of the mold conveying line 320, thus positioning the mold for the second time. Then, the conductive component picking robot 334 takes out the stationary contact 21 in the mold box 321 and assembles it on the base 1.

[0106] Optionally, such as Figure 6 and Figure 7 As shown, the stationary contact assembly feeding mechanism 310 also includes a die-splitting component 335. Along the conveying direction of the die-splitting conveyor line 320, the die-splitting component 335 is located upstream of the first die-splitting positioning component 331. The die-splitting component 335 allows the die-splitting boxes 321 to enter the first die-splitting positioning component 331 one by one, effectively avoiding blockage or positioning errors caused by multiple die-splitting boxes 321 arriving at the first die-splitting box 321 positioning component at the same time, thus ensuring the smoothness and stability of the stationary contact assembly feeding mechanism 310.

[0107] Optionally, such as Figure 6 and Figure 7As shown, the die-cutting and material distribution assembly 335 includes a die-cutting and material distribution sensor 3351, a fourth cylinder 3352, a first stop block 3353, a fifth cylinder 3354, and a second stop block 3355. The first stop block 3353 is connected to the piston rod of the fourth cylinder 3352, and the second stop block 3355 is connected to the piston rod of the fifth cylinder 3354. The die-cutting box 321 moves in the die-cutting conveyor line 320. After the die-cutting and material distribution sensor 3351 senses the die-cutting box 321, the fourth cylinder 3352 drives the first stop block 3353 to extend into the die-cutting conveyor line 320, blocking the first die-cutting box 321 to be distributed. The first die-cutting box 321 cannot move. The fifth cylinder 3354 drives the second stop block 3355. Block 3355 abuts against the side of the second mold box 321 to be dispensed, and the second mold box 321 cannot move; after the above actions are completed, the fourth cylinder 3352 moves to the original position, the first mold box 321 moves along the mold conveyor line 320 to the first mold positioning component 331, the fifth cylinder 3354 remains stationary, and the second mold box 321 remains stationary; after the first positioning sensor at the first mold positioning component 331 senses the material, the first cylinder 3311 and the second cylinder 3313 move to the end point, the first positioning block 3312 blocks the material, and the second positioning block 3314 pushes the mold from the side, and the first mold is completely positioned, waiting for the stationary contact picking robot to grab the stationary contact 21. After the stationary contact 21 completes the material handling, the first cylinder 3311 and the second cylinder 3313 move to the origin. The first die moves along the conveying direction of the die conveyor line 320. After the second sensor 5132 at the second die positioning component 333 senses the die, the third cylinder 3331 moves to the end point. The third positioning block 3332 holds the die in place, and the first die is completely positioned, waiting for the conductive component handling robot 334 to grab the conductive component 22.

[0108] Optionally, such as Figure 8 and Figure 9 As shown, the stationary contact assembly feeding mechanism 310 also includes a mold return line 336, a mold drive component 337, and a mold pusher plate 338. The mold return line 336 and the mold conveying line 320 are parallel to each other and have opposite conveying directions. The mold pusher plate 338 is connected to the output end of the mold drive component 337. Along the mold conveying direction, the mold drive component 337 is located at the top of the mold conveying line 320. The mold drive component 337 can drive the mold pusher plate 338 to move in a direction perpendicular to the mold conveying direction, so as to drive the empty mold box 321 to the mold return line 336. In this embodiment, the mold drive component 337 is a mold drive cylinder.

[0109] Specifically, after the conductive component picking robot 334 picks up the material, the third cylinder 3331 drives the third positioning block 3332 to retract, the third positioning block 3332 disengages from the mold, the mold driving cylinder moves to the origin position, and the mold pushing plate 338 moves the mold to the empty mold release position; in the next cycle, the first empty mold is moved to the empty mold discharge position, and the first empty mold moves along the conveying direction of the mold return line 336 to the end of the return conveying line; when all the multiple sensors at the end of the mold return line 336 sense the mold, the robot picks up the empty mold and puts it back into the mold loading machine, completing the cycle.

[0110] Optionally, such as Figure 10 As shown, the moving contact feeding mechanism 340 includes a vibration conveying component 341, a silver spot detection component 342, a moving contact dispensing component 343, and a moving contact picking robot 344. The vibration conveying component 341 includes a circular vibrating disk and a linear vibrating channel. One end of the linear vibrating channel is connected to the circular vibrating disk, and the other end of the linear vibrating channel is provided with a discharge port. The linear vibrating channel is used to convey the moving contact components 3 in the circular vibrating disk to the discharge port. The silver spot detection component 342 is set at the discharge port and is used to detect the direction of the silver spot of the moving contact components 3 at the discharge port. The moving contact dispensing component 343 is used to dispense several moving contact components 3 flowing out of the discharge port. The moving contact picking robot 344 is communicatively connected to the silver spot detection component 342 and is used to grab the dispensed moving contact components 3 and assemble the moving contact components 3 onto the base 1 according to the direction of the silver spot of the moving contact components 3. The moving contact feeding mechanism 340 realizes full-process automation from conveying to assembly, ensuring high efficiency, accuracy and consistency in assembly, and significantly improving product quality and production efficiency.

[0111] Optionally, such as Figure 11 As shown, the silver dot detection assembly 342 includes a first detection sensor 3421 and a second detection sensor 3422. The first detection sensor 3421 and the second detection sensor 3422 respectively detect both ends of the moving contact assembly 3. When both the first detection sensor 3421 and the second detector emit a material signal at the same time, it means that the moving contact assembly 3 is a dual-control moving contact assembly. When only one of the first detection sensor 3421 and the second detection sensor 3422 emits a material signal, it means that the moving contact assembly is a single-control moving contact assembly. The direction of the silver dot is recorded to facilitate subsequent assembly.

[0112] Optionally, such as Figure 12As shown, the moving contact dispensing assembly 343 includes a dispensing carrier 3431, a first dispensing drive 3432, and a second dispensing drive 3433. The dispensing carrier 3431 is provided with at least one receiving slot and a dispensing sensor corresponding to the receiving slot. The dispensing sensor is used to sense the moving contact assembly 3 in the receiving slot. The dispensing carrier 3431 is connected to the output end of the first dispensing drive 3432. The driving direction of the first dispensing drive 3432 is perpendicular to the discharge direction of the direct vibration channel. The first dispensing drive 3432 is disposed on the second dispensing drive 3433. The second dispensing drive 3433 is used to drive the dispensing carrier 3431 to move to the moving contact picking robot 344. In this embodiment, for example, the first dispensing drive unit 3432 and the second dispensing drive unit 3433 are respectively the first dispensing cylinder and the second dispensing cylinder. The dispensing carrier 3431 is provided with two receiving slots and two dispensing sensors. The two receiving slots are the first receiving slot 34311 and the second receiving slot 34312. The two dispensing sensors are the first dispensing sensor 34313 and the second dispensing sensor 34314. The first dispensing sensor 34313 is used to sense whether there is a moving contact assembly 3 in the first receiving slot 34311. The second dispensing sensor 34314 is used to sense whether there is a moving contact assembly 3 in the second receiving slot 34312. After the moving contact assembly 3 completes the silver dot direction determination, the first dispensing... When the first dispensing cylinder reaches its endpoint (i.e., the piston rod of the first dispensing cylinder extends), and the second dispensing cylinder returns to its origin (i.e., the piston rod of the second dispensing cylinder retracts), the first moving contact assembly moves from the outlet into the first receiving groove 34311 under the vibration force of the direct vibration channel, and the first dispensing sensor 34313 sends a material presence signal. The second dispensing cylinder remains at its origin, and the first dispensing cylinder returns to its origin. The second moving contact assembly enters the second receiving groove 34312 from the outlet under the push of the direct vibration channel, and the second dispensing sensor 34314 sends a material presence signal. The first dispensing cylinder remains at its origin, and the second dispensing cylinder reaches its endpoint. The two moving contacts are completely isolated from the material channel of the direct vibration channel, completing the dispensing process.

[0113] After the moving contact assembly completes the material distribution, the moving contact picking robot 344 starts to run to the first receiving slot 34311. The first vacuum valve on the moving contact picking robot 344 is activated, and the first suction nozzle picks up the material. The moving contact picking robot 344 runs to the second picking position, the second vacuum valve on the moving contact picking robot 344 is activated, and the second suction nozzle picks up the material. The moving contact picking robot 344 then assembles the moving contact assembly 3 onto the base 1.

[0114] Optionally, such as Figure 4 and Figure 13As shown, the conveying unit 100 includes a belt conveyor 110, a base handling robot 120, and a carrier conveyor 130. The carrier conveyor 130 is equipped with several base carriers 131. The base handling robot 120 is positioned between the belt conveyor 110 and the carrier conveyor 130. The belt conveyor 110 transports the base 1 to the base handling robot 120, which then moves the base 1 from the belt conveyor 110 to the base carriers 131 on the carrier conveyor 130. The carrier conveyor 130 sequentially transports the base carriers 131 carrying the base 1 to the conductive component assembly station, the button component assembly station, and the panel assembly station. In this embodiment, the conveying unit 100 is divided into two sections. The belt conveyor 110 improves the initial conveying efficiency of the base 1, while the carrier conveyor 130, by supporting the base 1 with the base carriers 131, ensures greater stability of the base 1 and improves assembly accuracy. It should be noted that in the carrier conveyor line 130, several bases 1 are driven to move forward along the carrier conveyor line 130 by a base feeding mechanism. The base feeding mechanism is existing technology and will not be described in detail here.

[0115] Optionally, the base loading unit 200 includes a pallet 210, a pallet transfer mechanism 220, and a base transport mechanism 230. The pallet 210 has a receiving slot 2101 that can hold various types of bases 1. The pallet transfer mechanism 220 is used to transport the pallet 210 to the base transport mechanism 230, which is used to transport the bases in the pallet 210 to the conveying unit 100, thereby completing the loading of the bases 1. The pallet 210 can accommodate different types of bases 1, eliminating the need for frequent pallet 210 replacements or adjustments to the configuration of the base loading unit 200. This improves the adaptability of the base loading unit 200, saves time and costs associated with replacement and debugging, and increases production efficiency.

[0116] Optionally, such as Figure 14 and Figure 15As shown, the pallet transfer mechanism 220 includes a pallet conveyor line 2201, a pallet sorting component 223, a pallet feeding component 224, and a pallet stacking component 225. The pallet conveyor line 2201 includes an inbound conveyor line 221 and an outbound conveyor line 222. The inbound conveyor line 221 and the outbound conveyor line 222 are located on the same plane and have opposite conveying directions. Along the conveying direction of the inbound conveyor line 221, an inbound pallet station 2210 and a sorting pallet station 2211 are arranged in sequence on the inbound conveyor line 221, and the pallet sorting component 223 is arranged at the sorting pallet station 2211. Along the conveying direction of the outbound conveyor line 222, a picking pallet station 2220 and an outbound pallet station 2221 are arranged in sequence on the outbound conveyor line 222, and the pallet stacking component 225 is arranged at the outbound pallet station 2221. During the loading of base 1, multiple stacked pallets 210 are first placed in pallet infeed station 2210 by AGV trolley. Infeed conveyor line 221 transports the stacked pallets 210 from pallet infeed station 2210 to pallet distribution station 2211. Pallet distribution component 223 is set in pallet distribution station 2211. Pallet distribution component 223 is used to lift the multiple stacked pallets 210 on pallet distribution station 2211 and distribute them one by one to pallet distribution station 2211. Subsequently, pallet feeding component 224 carries several base 1 pallets to be loaded. A single pallet 210 is moved to the picking station 2220, where the base transport mechanism 230 removes the base 1 from the pallet 210 and places it on the conveying unit 100 to the conductive component assembly station. Empty pallets 210 are conveyed into the pallet exit station 2221 by the outgoing conveyor line 222. The pallet stacking assembly 225 stacks the empty pallets 210 sequentially in the pallet exit station 2221. After a certain number are stacked, the AGV trolley removes the stacked pallets 210, completing the loading process of the base 1 and the circulation process of the pallets 210. The pallet circulation mechanism 220, through the close cooperation of the ingoing conveyor line 221, the outgoing conveyor line 222, the pallet sorting assembly 223, the pallet picking assembly 224, and the pallet stacking assembly 225, achieves efficient sorting, conveying, and stacking of pallets 210.

[0117] Optionally, such as Figure 16 As shown, the pallet transfer mechanism 220 also includes a pallet blocking assembly 226. The pallet blocking assembly 226 includes a pallet blocking cylinder 2261 and a baffle plate 2262. The pallet blocking cylinder 2261 is located between the pallet feeding station 2210 and the pallet separating station 2211. The baffle plate 2262 is located on the output end of the pallet blocking cylinder 2261. When the pallet separating station 2211 is separating pallets, the pallet blocking cylinder 2261 drives the baffle plate 2262 to extend upward, preventing stacked pallets 210 from entering the pallet separating station 2211. After the pallet separating is completed, the pallet blocking cylinder 2261 drives the first pallet 210 to descend, allowing the next stack of pallets 210 to enter the pallet separating station 2211 for further separation. The pallet blocking assembly 226 can effectively control the flow of stacked pallets 210, improving the pallet separating efficiency.

[0118] Optionally, such as Figure 17 , Figure 18 and Figure 19 As shown, the pallet distribution assembly 223 includes a distribution lifting drive 2231, a distribution lifting plate 2232, a first material support drive 2233, and a first material support plate 2234. The distribution lifting drive 2231 is located below the distribution station 2211. The distribution lifting plate 2232 is connected to the output end of the distribution lifting drive 2231. At least two first material support drives 2233 are respectively located on both sides of the distribution station 2211. The output end of each first material support drive 2233 is provided with a first material support plate 2234. During the tray sorting process, the sorting lifting drive 2231 drives the sorting lifting plate 2232 to lift the stacked trays 210 vertically. After rising to a certain height, the two first material support drive components 2233 drive their corresponding first material support plates 2234 to move horizontally, so that at least part of the first material support plates 2234 are inserted between the first tray 210 and the second tray 210 from bottom to top. Then, the sorting lifting drive 2231 continues to drive the sorting lifting plate 2232 to continue to descend. The first tray 210 falls onto the sorting station 2211 with the sorting lifting plate 2232. The remaining stacked trays are supported by the two lifting plates, completing one tray 210 sorting. Repeating the above actions can sort the stacked trays 210 one by one to the sorting station. The pallet separating assembly 223, through the coordinated operation of the separating lifting drive 2231, the first material supporting drive 2233, and the first material supporting plate 2234, achieves automated, stable, and efficient separation of the pallet 210, reducing manual operation and improving the automation level and operating efficiency of the production line. In this embodiment, the separating lifting drive 2231 and the first material supporting drive 2233 are the separating lifting cylinder and the first material supporting cylinder, respectively.

[0119] Optionally, such as Figure 20 and Figure 21As shown, the pallet feeding assembly 224 includes a feeding conveyor belt assembly 2241, a feeding lifting assembly 2242, and a feeding drive motor 2243. The moving end of the feeding conveyor belt assembly 2241 is provided with the feeding lifting assembly 2242, which is used to lift the pallet 210. The feeding drive motor 2243 is connected to the feeding conveyor belt assembly 2241. The feeding conveyor belt assembly 2241 enables the feeding lifting assembly 2242 to move between the tray sorting station 2211 and the picking station 2220 to move the pallet 210 from the tray sorting station 2211 to the picking station 2220. In this embodiment, a material feeding conveyor belt assembly 2241 is respectively set on both sides of the material feeding station. Each material feeding conveyor belt assembly 2241 has a material feeding support assembly 2242 at its moving end, thereby supporting the pallet 210 on both sides during material feeding, ensuring that the pallet 210 is subjected to balanced forces and has stability during the feeding process. The material feeding conveyor belt assembly 2241 in this embodiment is prior art and will not be described in detail.

[0120] Optionally, such as Figure 22 As shown, the material lifting assembly 2242 includes a material lifting cylinder 22421 and a material lifting plate 22422. The material lifting plate 22422 is connected to the output end of the material lifting cylinder 22421. The material lifting cylinder 22421 can drive the material lifting plate 22422 to rise vertically, separating the pallet 210 from the material distribution station. Then, the material lifting assembly drives the pallet 210 lifted by the material lifting cylinder 22421 to move to the material picking station 2220. The material lifting cylinder 22421 can drive the material lifting plate 22422 to descend vertically, placing the pallet 210 in the material picking station 2220. The material lifting cylinder 22421 drives the material lifting plate 22422 to rise or fall vertically, which can precisely control the moving height of the pallet 210, ensuring accurate docking with the pallet, thereby reducing offset or error and improving the reliability of material lifting.

[0121] Optionally, such as Figure 21 As shown, the pallet transfer mechanism 220 also includes a first pallet positioning component 227 and a second pallet positioning component 228. The first pallet positioning component 227 and the second pallet positioning component 228 are used to position the pallet 210 of the material picking station 2220 to ensure the stability of the pallet 210 position and improve the material picking accuracy.

[0122] Specifically, such as Figure 23As shown, the first pallet positioning assembly 227 includes a first positioning cylinder 2271, a first positioning plate 2272, and a first stop block 2273. The first stop block 2273 is located on the left side of the material picking station 2220, and the first positioning cylinder 2271 is located on the right side of the material picking station 2220. The first positioning plate 2272 is connected to the piston rod of the first positioning cylinder 2271. The first positioning cylinder 2271 drives the first positioning plate 2272 to rise, so that the left and right ends of the pallet 210 abut against the first positioning plate 2272 and the first stop block 2273, respectively. The second pallet positioning assembly 2271 includes a first positioning cylinder 2271, a first positioning plate 2272, and a first stop block 2273. Positioning component 228 includes a second positioning cylinder 2281, a second positioning plate 2282, and a second stop 2283. The second stop 2283 is located behind the material picking station 2220, and the second positioning cylinder 2281 is located in front of the material picking station 2220. The second positioning plate 2282 is connected to the piston rod of the second positioning cylinder 2281. The second positioning cylinder 2281 drives the second positioning plate 2282 to rise, so that the front and rear ends of the tray 210 abut against the second stop 2283 and the second positioning plate 2282 respectively, thereby completely positioning the tray 210.

[0123] Optionally, such as Figure 24 and Figure 25As shown, the pallet stacking assembly 225 includes a second material-supporting drive 2251, a mounting plate 2252, a second material-supporting plate 2253, a first elastic member 2254, a stacking drive 2255, and a stacking pallet 2256. At least two second material-supporting drive members 2251 are respectively disposed on both sides of the pallet discharge station 2221. The output end of each second material-supporting drive member 2251 is provided with a mounting plate 2252. The first end of the second material-supporting plate 2253 is rotatably connected to the mounting plate 2252. One end of the first elastic member 2254 abuts against the mounting plate 2252, and the other end abuts against the second end of the second material-supporting plate 2253. The stacking drive 2255 is disposed below the pallet discharge station 2221. The output end of the stacking drive 2255 is provided with a stacking pallet 2256. The stacking drive 2255 is used to drive the stacking pallet 2256 to lift the empty pallet 210 onto the second material-supporting plate 2253. In this embodiment, the second material-supporting drive component 2251 and the stacking drive component 2255 are respectively the second material-supporting cylinder and the stacking cylinder. Specifically, the first elastic member 2254 can cause the second end of the second material-supporting plate 2253 to protrude towards the inside of the tray exit station 2221. When the stacking cylinder drives the empty tray 210 to rise, the empty tray 210 can squeeze the second end of the second material-supporting plate 2253. The second material-supporting plate 2253 rotates around its axis, and the first elastic member 2254 is compressed. When the height of the tray 210 is higher than that of the second material-supporting plate 2253, the second end of the second material-supporting plate 2253 pops out under the elastic force of the first elastic member 2254, supporting the empty tray 210. Repeating the above steps multiple times can stack multiple empty trays 210 on the tray exit station 2221. After stacking to a certain height, the AGV trolley takes away the stack of empty trays 210. This material-supporting and stacking component has a simple structure and high stacking efficiency.

[0124] Because the base 1 has a large front area and a small back area, when placing the base 1 in the tray 210, it is placed upside down on the tray 210 to increase the contact area between the base 1 and the tray 210, ensuring the stability of the base 1 within the tray 210. Therefore, the base handling mechanism 230 is set to rotate the base 1 180° before placing it into the conveying unit 100, facilitating the subsequent assembly of conductive components into the base 1. Specifically, as... Figure 26 and Figure 27As shown, the base transport mechanism 230 includes a first flipping component 231 and a base transport robot 232. The first flipping component 231 includes a first lifting drive 2311, a first flipping drive 2312, a first clamping drive 2313, and a gripper 2314. The first flipping drive 2312 is disposed on the output end of the first lifting drive 2311, the first clamping drive 2313 is disposed on the output end of the flipping drive workpiece, and the gripper 2314 is connected to the output end of the first clamping drive 2313. The base transport robot 232 transports the base 1 from the picking station 2220 to the gripper 2314 and is clamped by the gripper 2314. After the first flipping drive 2312 flips the base 1 by a preset angle (in this embodiment, the preset angle is 180°), the first lifting drive 2311 moves the flipped base 1 to the conveying unit 100. The base handling mechanism 230, through the precise cooperation of the first flipping component 231 and the base handling robot 232, automatically completes the flipping and handling tasks of the base, which not only improves the stability of the base 1 in the pallet 210, but also provides convenience for the subsequent assembly process.

[0125] Optionally, such as Figure 28 As shown, the wall switch production line also includes a panel assembly unit 500. Along the conveying direction of the conveying unit 100, the panel assembly unit 500 is located downstream of the conductive component assembly unit. The panel assembly unit 500 includes a panel loading robot 520, a pressing mechanism 530, and an appearance inspection mechanism 540 arranged in sequence. The carrier conveyor line 130 conveys the base 1 with the assembled button assembly to the panel loading robot 520. The panel loading robot 520 moves the panel onto the base 1. Then, the pressing mechanism 530 presses the panel onto the corresponding base 1. Subsequently, the carrier conveyor line 130 conveys the wall switch to the appearance inspection mechanism 540. The appearance inspection mechanism 540 performs appearance inspection on the assembled wall switch. Qualified products are transferred to the good product discharge position, where the good product discharge module picks up the finished product and discharges it onto the discharge conveyor belt. Unqualified products are transferred to the defective product discharge position via the base carrier 131, where the defective product discharge module picks up the defective product and discharges it into the defective product channel. Empty base carrier 131 is transported and transferred by the return cylinder and enters the return conveyor belt, completing the return of base carrier 131.

[0126] Optionally, the pressing mechanism 530 includes a pressing cylinder 531 and a pressing plate 532. The pressing plate 532 is connected to the piston rod of the pressing cylinder 531. The pressing cylinder 531 can drive the pressing plate 532 to move in the vertical direction, thereby assembling the panel onto the base 1.

[0127] In this embodiment, the appearance inspection mechanism 540 includes a first CCD camera, which can perform appearance inspection on the assembled wall switch to ensure the quality of the wall switch.

[0128] Example 2

[0129] This embodiment provides a switch testing device 510 for performing a tactile test on the wall switch produced in Embodiment 1, such as... Figure 29 The switch testing device 510 shown includes a mounting frame 515, a tactile detection drive 511, a moving block 5111, a pressing rod 512, and a sensor assembly 513. A base carrier 131 is mounted on the mounting frame 515 to support the wall switch. The tactile detection drive 511 is mounted on the mounting frame 515. The moving block 5111 is vertically slidably mounted on the mounting frame 515. The output end of the tactile detection drive 511 is connected to the moving block 5111. The pressing rod 512 is vertically slidably mounted on the moving block. The moving block 5111 is elastically connected to the pressing rod 512. The pressing rod 512 is provided with a first sensing part 5121 and a second sensing part 5122 at intervals. The second sensing part 5122 is located above the first sensing part 5121. The sensor assembly 513 is disposed on the moving block 5111. The sensor assembly 513 can detect the movement position of the first sensing part 5121 and the second sensing part 5122 to detect the pressing resistance of the upper button 41 on the panel, so as to ensure that the pressing resistance of the produced wall switch is within a suitable range and improve the user experience.

[0130] The switch testing device 510 provided in this embodiment detects the position changes of the first sensing part 5121 and the second sensing part 5122 through the sensor assembly 513, and measures the resistance value change of the button 41 at different pressing stages. This ensures that the pressing resistance of the produced wall switch is within a suitable range, reduces manual intervention in the testing process, effectively improves testing efficiency, and ensures the stability and reliability of the test results.

[0131] Optionally, the sensor assembly 513 includes a first sensor 5131 and a second sensor 5132, which are vertically spaced on the moving block 5111. The tactile detection drive 511 drives the moving block 5111 to descend, and the pressing rod 512 can elastically abut against the button 41 on the panel. The first sensor 5131 and the second sensor 5132 respectively detect the movement position of the first sensing part 5121 and the second sensing part 5122 on the pressing rod 512 to detect the pressing resistance of the button 41.

[0132] In this embodiment, the tactile detection drive 511 is a tactile detection drive cylinder. The switch testing device 510 includes a second elastic element 514. The moving block 5111 is provided with an assembly groove 51111. The pressing rod 512 slides through the assembly groove 51111, with both ends of the pressing rod 512 extending out of the assembly groove 51111. The second elastic element 514 is sleeved on the pressing rod 512. One end of the second elastic element 514 abuts against the top wall of the assembly groove 51111, and the other end abuts against the protrusion on the pressing rod 512.

[0133] Before conducting the tactile test, the first sensing unit 5121 faces the first sensor 5131, and the second sensing unit 5122 is located below the second sensor 5132. During the tactile detection, after the base 1 carried by the base carrier 131 reaches the tactile detection position, the tactile detection drive cylinder moves to the end point (the piston rod of the tactile detection cylinder extends), the pressure rod 512 contacts the button and begins to move upward, the second elastic element 514 is compressed to the minimum resistance range, the first sensing unit 5121 disengages from the first sensor 5131, and the first sensor 5131 emits a first signal; as the pressure rod 512 continues to move upward, the second elastic element 514 is compressed to the maximum resistance range, the second sensing unit triggers the second sensor, the second sensor 5132 emits a second signal, and the button 41 on the panel is toggled to the normally open or normally closed position. If the product resistance is too high or too low, and the first sensor 5131 and / or the second sensor 5132 is not triggered, it will be judged as unqualified.

[0134] Example 3

[0135] like Figure 30 As shown, this embodiment provides a switch testing method, applied in the switch testing device 510 of Embodiment 2. A detection position is set below the tactile detection drive 511. The switch testing method includes:

[0136] The touch detection drive unit 511 receives a start signal. The start signal is generated when the carrier conveyor line 130 drives the base carrier 131 carrying the wall switch to the detection position. The touch detection drive unit 511 drives the moving block 5111 to descend in the vertical direction. The pressing rod 512 descends with the moving block 5111 and elastically abuts against the button 41 on the wall switch. The pressing rod 512 rises relative to the moving block 5111.

[0137] The first sensing unit 5121 causes the first sensor 5131 to generate a first signal and sends the first signal to the controller; and / or, the second sensing unit 5122 causes the second sensor 5132 to generate a second signal and sends the second signal to the controller;

[0138] The controller determines whether the pressing resistance of button 41 is qualified based on the received first signal and / or second signal.

[0139] The switch testing method provided in this embodiment can perform pressing resistance tests on various models of wall switches. It is highly adaptable and flexible, and can meet the testing needs of different product specifications and performance requirements. It reduces labor costs, avoids testing errors caused by human factors, and improves the reliability and accuracy of the test.

[0140] Specifically, before conducting the tactile test, the first sensing unit 5121 faces the first sensor 5131, and the second sensing unit 5122 is located below the second sensor 5132. When the wall switch needs to be tested, after the base supported by the base carrier 131 reaches the tactile detection position, the tactile detection drive cylinder receives the start signal and moves to the end point (the piston rod of the tactile detection cylinder extends). The pressure rod 512 contacts the button and begins to move upward. The second elastic element 514 is compressed to the minimum resistance range, the first sensing unit 5121 disengages from the first sensor 5131, and the first sensor 5131 emits a first signal. As the pressure rod 512 continues to move upward, the second elastic element 514 is compressed to the maximum resistance range. The second sensing unit triggers the second sensor, and the second sensor 5132 emits a second signal. The button 41 on the panel is toggled to the normally open or normally closed position. If the product resistance is too high or too low, and the first sensor 5131 and / or the second sensor 5132 is not triggered, it will be judged as unqualified.
