[0069] Wall switches are an important component of home electrical control, widely used in homes, offices, and industrial facilities to control the on / off state of electrical equipment. The toggle switch is a key component controlling the on / off state of the wall switch, typically consisting of a toggle assembly 10 and a pressure plate 20, such as... Figure 1 This is an exploded view of the knob in a common single-pole, single-control wall switch in existing technology. Figure 2 This is an exploded view of the button in a common double-pole double-control wall switch in existing technology. Currently, the assembly of the button assembly 10 and the pressure plate 20 is usually done manually. The assembly process is time-consuming and labor-intensive, resulting in low assembly efficiency and inconsistent product quality after assembly.

[0070] Therefore, such as Figures 3-13As shown, this embodiment provides a button assembly device, including a multi-station assembly mechanism 410, a pressure plate feeding mechanism 420, a button assembly feeding mechanism 430, and a first pressing mechanism 414. The multi-station assembly mechanism 410 includes a station turntable 413. Along the rotation direction of the station turntable 413, the pressure plate feeding mechanism 420, the button assembly feeding mechanism 430, and the first pressing mechanism 414 are sequentially arranged on the periphery of the station turntable 413. Multiple assembly carriers 413 are spaced apart on the station turntable 413. 1. The platen loading mechanism 420 is used to transport the platen to the assembly carrier 4131, the button assembly loading mechanism 430 is used to transport the button assembly to the platen 20 in the assembly carrier 4131, and the first pressing mechanism 414 is used to press the button assembly 10 onto the platen 20. The platen 20 and the button assembly 10 are assembled on the rotating workstation turntable 413, which reduces labor intensity, saves production space, improves assembly efficiency, ensures the consistency of the assembled products, and improves product quality.

[0071] like Figure 1 and Figure 2 As shown, wall switches can generally be divided into four types: single-pole single-control switch, single-pole double-control switch (not shown), double-pole single-control switch (not shown), and double-pole double-control switch. The width of the pressure plate 20 of the single-pole single-control switch and the single-pole double-control switch is a, and the width of the pressure plate 20 of the double-pole single-control switch and the double-pole double-control switch is b, where b > a.

[0072] like Figure 4 As shown, in order to enable the button assembly equipment to be compatible with the assembly of different models of wall switches, the pressure plate feeding mechanism 420 includes a pressure plate positioning component 423. The pressure plate positioning component 423 includes a positioning fixture 4231, a first positioning plate 4232, and a first positioning drive 4233. The positioning fixture 4231 is located at the end of the pressure plate conveyor line 421. The positioning fixture 4231 is provided with a positioning groove with adjustable width. The first positioning plate 4232 is slidably disposed on the positioning fixture 4231. The first positioning plate 4232 is connected to the output end of the first positioning drive 4233. The first positioning drive 4233 is used to drive the pressure plate 20 to slide along the positioning fixture 4231 to change the width of the positioning groove, so that the pressure plate feeding conveyor line can adapt to pressure plates 20 of different specifications, thereby improving the flexibility of the pressure plate feeding conveyor line.

[0073] Optionally, the pressure plate handling robot 422 includes an incoming material detection component 4211, a material transfer conveyor belt assembly 4221, a material transfer drive motor 4222, a rotary drive component 4223, and a gripping component 4224. The incoming material detection component 4211 is used to detect the incoming direction of the pressure plate 20. The output end of the material transfer drive motor 4222 is connected to the input end of the material transfer conveyor belt assembly 4221. The rotary drive component 4223 is located on the output end of the material transfer conveyor belt assembly 4221. The gripping component 4224 is located on the output end of the rotary drive component 4223. The gripping component 4224 can grip the pressure plate 20. The rotary drive component 4223 is communicatively connected to the incoming material detection component 4211. According to the incoming direction of the pressure plate 20, the rotary drive component 4223 adjusts the pressure plate 20 to place it in the correct direction on the base in the assembly carrier 4131.

[0074] In this embodiment, the specific structure of the material transfer conveyor belt assembly 4221 is the prior art and will not be described in detail here. The incoming material detection component 4211 can be a photoelectric sensor, the rotary drive component 4223 can be a rotary cylinder, and the gripping component 4224 is a gripping robot.

[0075] like Figure 1 and Figure 2 As shown, the button assembly 10 includes a button body 11, a spring 12, and a pressure rod 13. The button body 11 has a mounting hole. During assembly, the spring 12 needs to be placed in the mounting hole first, and then the pressure rod 13 is assembled at the upper opening of the mounting hole. A certain pressure is applied to the pressure rod 13 so that the pressure rod 13 is interference-fitted with the hole wall of the mounting hole.

[0076] Optionally, the button assembly feeding mechanism 430 includes a button assembly mechanism 431 and a button conveying assembly 433. The button assembly mechanism 431 is used to assemble the button, spring 12 and pressure rod 13 constituting the button assembly 10, and the button conveying assembly 433 is used to convey the assembled button assembly 10 onto the pressure plate 20.

[0077] like Figure 5 and Figure 6As shown, the button assembly mechanism 431 includes a spring feeding assembly 4311, a push rod feeding assembly 4312, and a button body conveyor line 4313. The spring feeding assembly 4311 includes a spring discharge pipe 43111 and a spring discharge nozzle 43112. The spring discharge pipe 43111 is connected to the spring discharge nozzle 43112, and at least one spring is stored in the spring discharge pipe 43111. The push rod feeding assembly 4312 is disposed on one side of the spring feeding assembly 4311, and includes a push rod discharge pipe 43121 and a push rod discharge pipe 43122. The push rod discharge nozzle 43122 and the push rod discharge pipe 43121 are connected to the push rod discharge nozzle 43122. The push rod discharge pipe 43121 stores at least one push rod 13. The button body conveying line 4313 is used to sequentially convey the button body 11 to the area below the spring discharge nozzle 43112 and the push rod discharge nozzle 43122. The spring discharge pipe 43111 and the push rod discharge pipe 43121 can be connected to an air source. The air source sequentially blows the spring 12 and the push rod 13 into the button body 11, thereby preparing for subsequent pressing.

[0078] In this embodiment, the air source can be an air pump. The air pump is connected to the spring discharge pipe 43111 and the push rod discharge pipe 43121 through the main air pipe and two branch pipes respectively. Specifically, one end of the main air pipe is connected to the air outlet of the air pump, and the other end is connected to the air inlet of the three-way solenoid valve. The two air outlets of the three-way solenoid valve are connected to a branch pipe respectively. The flow direction of the airflow in the main air pipe is controlled by the three-way solenoid valve, so as to blow the spring 12 and the push rod 13 into the button body 11 respectively.

[0079] Optionally, such as Figure 6As shown, the spring feeding assembly 4311 also includes a first lifting cylinder 43113 and a first mounting plate 43114. The spring discharge nozzle 43112 is disposed on the first mounting plate 43114. The push rod feeding assembly 4312 also includes a second lifting cylinder 43123 and a second mounting plate 43124. The push rod discharge nozzle 43122 is disposed on the second mounting plate 43124. An oil-filling cylinder 4341 is provided between the first cylinder and the second cylinder, and the piston rod of the oil-filling cylinder 4341 is connected to the oil-filling nozzle 4342. During assembly, after the button body 11 reaches the spring assembly position in the button body conveyor line 4313, the first lifting cylinder 43113 runs to the end position (the piston rod of the first lifting cylinder 43113 extends), the spring discharge nozzle 43112 presses down the button body 11, and compressed air begins to enter the spring discharge pipe 43111, and the spring is assembled into the button body 11. To ensure the lubrication of the spring and prevent it from jamming, an oiling station is provided between the button assembly station and the push rod assembly station. The oiling station is equipped with a button oiling assembly 434, which includes an oiling cylinder 4341 and an oiling nozzle 4342. The oiling nozzle 4342 is connected to the piston rod of the oiling cylinder 4341. After the button body 11 reaches the oiling station, the oiling cylinder 4341 moves to its end position (the piston rod of the oiling cylinder 4341 extends), and the oiling nozzle 4342 injects lubricating oil into the spring. After reaching the push rod assembly station, the second lifting cylinder 43123 moves to its end position (the piston rod of the second lifting cylinder 43123 extends), and the push rod discharge nozzle 43122 presses down on the button body 11. Compressed air begins to enter the push rod discharge pipe 43121, and the push rod material is assembled into the button body 11.

[0080] like Figure 6 As shown, the spring discharge tube 43111 has a first spiral section 431111 in the middle to prevent the spring inside the spring discharge tube 43111 from falling out of the spring discharge nozzle 43112 without air pressure, thus temporarily storing the spring inside the spring discharge tube 43111. Similarly, the push rod discharge tube 43121 has a second spiral section 431211 in the middle to prevent the push rod inside the push rod discharge tube 43121 from falling out of the push rod discharge nozzle 43122 without air pressure, thus temporarily storing the push rod 13 inside the push rod discharge tube 43121.

[0081] Optionally, such as Figure 7As shown, the spring feeding assembly 4311 also includes a spring conveying pipe 43115, a first distributing drive 43117, a first distributing needle 43116, a second distributing drive 43119, and a second distributing needle 43118. The spring conveying pipe 43115 is connected to the spring discharge pipe 43111. The first distributing drive 43117 is located at the connection between the spring conveying pipe 43115 and the spring discharge pipe 43111. The first distributing needle 43116 is connected to the output end of the first distributing drive 43117. The second distributing drive 43119 is located above the first distributing drive 43117. The second distributing needle 43118 is connected to the output end of the second distributing drive 43119.

[0082] In this embodiment, the first material distribution drive 43117 is a first spring material distribution cylinder, and the second material distribution drive 43119 is a second spring material distribution cylinder. During material distribution, the spring 12 enters the spring conveying pipe 43115 through the spring vibrating plate and the spring direct vibration channel. When multiple springs 12 move sequentially to the junction of the spring conveying pipe 43115 and the spring discharge pipe 43111, the second spring material distribution cylinder moves to the origin, the second material distribution needle 43118 retracts, the first material distribution needle 43116 extends, and the first spring is stopped. Subsequently, the second spring material distribution moves to the end point, the second material distribution needle 43118 extends, the first material distribution needle 43116 retracts, and the first spring runs in the spring discharge pipe 43111, at which time the spring discharges material. The first spiral section 431111 on the tube 43111 ensures that the spring will not fall off the spring outlet 43112. When the button body 11 moves along the button body conveyor line 4313 to directly below the spring outlet 43112, the first lifting cylinder 43113 drives the spring outlet 43112 to abut against the button body 11. The spring outlet 43112 aligns with the assembly hole. After receiving the assembly signal, compressed air enters the spring outlet tube 43111, and the spring 12 quickly enters the assembly hole of the button body 11 under the push of the compressed air, completing the spring assembly. It should be noted that the material distribution process of the push rod 13 is the same as that of the spring 12, and will not be described in detail.

[0083] Optionally, the button body conveying line 4313 includes a button vibrating plate, a button straight vibration channel 4314, a button turning assembly 4315, a button feeding channel 4316, and a button feeding assembly 4317. The button body 11 is conveyed to the button straight vibration channel 4314 via the button vibrating plate. The button straight vibration channel 4314 conveys the button body 11 to the turning assembly for turning. After turning, the button body 11 is driven by the button feeding assembly 4317 to move along the button feeding channel 4316. The button feeding assembly 4317 can move the button body 11 sequentially to the area below the spring outlet 43112 and the push rod outlet 43122 for assembling the spring 12 and the push rod 13.

[0084] Optionally, such as Figure 8 As shown, the button turning assembly 4315 includes a turning cylinder 43151 and a turning fixture 43152. The turning fixture 43152 is connected to the output end of the turning cylinder 43151. The turning fixture 43152 can be rotated by a preset angle by the driving of the turning cylinder 43151. In this embodiment, the button direct vibration channel 4314 is perpendicular to the button feeding channel 4316. Therefore, in this example, the turning cylinder 43151 can drive the turning fixture 43152 to rotate 90°.

[0085] Optionally, such as Figure 8 As shown, the button feeding assembly 4317 includes a button feeding moving cylinder 43171, a feeding fixture cylinder 43172, and a feeding fixture 43173. The feeding fixture 43173 is connected to the piston rod of the feeding fixture cylinder 43172. The feeding fixture cylinder 43172 is mounted on the piston rod of the feeding moving cylinder 43171. The feeding fixture cylinder 43172 drives the feeding fixture 43173 to engage with the button body 11 on the button feeding channel 4316. Then, by extending and retracting the piston rod of the feeding moving cylinder 43171, the feeding fixture 43173 moves along the feeding channel, thereby enabling the button body 11 to move forward along the feeding channel.

[0086] Optionally, such as Figure 6 and Figure 9 As shown, the button assembly mechanism 431 also includes a second pressing mechanism 432. A spring feeding assembly 4311, a push rod feeding assembly 4312, and a second pressing mechanism 432 are sequentially arranged along the conveying direction of the button feeding channel 4316. The second pressing mechanism 432 includes a fixed frame 4327, a pressing drive 4321, and a pressing pin 4322. The pressing drive 4321 is mounted on the fixed frame 4327. The pressing pin 4322 is connected to the output end of the pressing drive 4321. The pressing drive 4321 drives the pressing pin 4322 to abut against the push rod 13 and press the push rod 13 into the button body 11, so that the button body 11, spring 12, and push rod 13 form a combination. This second pressing mechanism 432 has a simple structure, high pressing efficiency, and improves production efficiency. In this embodiment, the pressing drive 4321 is a pressing cylinder.

[0087] Optionally, such as Figure 9As shown, the second pressing mechanism 432 also includes a first pressing plate 4323, a through rod 4324, a second pressing plate 4325, and a third elastic element 43241. The first pressing plate 4323 is connected to the output end of the pressing drive 4321. One end of the through rod 4324 is connected to the first pressing plate 4323, and the other end slides through the second pressing plate 4325. The third elastic element 43241 is sleeved on the through rod 4324. One end of the third elastic element 43241 abuts against the first pressing plate 4323, and the other end abuts against the second pressing plate 4325. The pressing pin 4322 is disposed on the second pressing plate 4325. This buffer structure can effectively reduce the risk of damage to the pressing rod or pressing pin 4322 due to excessive pressing force, extend the service life of the second pressing mechanism 432, and improve the product yield.

[0088] Optionally, such as Figure 6 As shown, the button assembly mechanism 431 also includes a button detection component 4326, which is located downstream of the second pressing mechanism 432. The button detection component 4326 includes a button detection drive component 43261, a button detection pin 43262, a tray fixture 43263, and a tray drive component. The button detection pin 43262 is located at the output end of the button detection drive component 43261 and can abut against the push rod 13 to determine whether the push rod 13 is assembled correctly. The tray fixture 43263 is located at the end of the button feeding channel 4316. The tray fixture 43263 is used to carry the button assembly 10 to be inspected. The output end of the tray drive is connected to the tray fixture 43263. The tray drive is communicatively connected to the button detection needle 43262 to ensure that when a defect is detected, the tray drive drives the tray fixture 43263 to be pulled away from the bottom of the button assembly 10. The button assembly 10 loses support and falls into the defective product box. The qualified products continue to run to the flipping station described below.

[0089] Since the structure of the button body 11 is approximately T-shaped, when assembling the spring 12 and the push rod 13, the button body 11 is placed in an inverted T-shape on the button body conveyor line 4313 for transmission, which facilitates the assembly of the spring 12 and the push rod 13. After assembly, the button assembly 10 needs to face the base with the side with the push rod 13. Therefore, before entering the multi-station assembly mechanism 410, the button assembly 10 needs to be rotated 180°.

[0090] Specifically, such as Figure 10As shown, the button handling assembly 433 includes a button assembly conveyor line 4331, a flipping assembly 4332, and a button assembly handling robot 4333. The button assembly conveyor line 4331 is arranged parallel to the button feeding channel 4316. The flipping assembly 4332 is located between the button detection assembly 4326 and the button assembly conveyor line 4331. The flipping assembly 4332 is used to flip the detected button assembly 10 at a preset angle and place it on the button assembly conveyor line 4331. The button assembly handling robot 4333 is located at the end of the button assembly conveyor line 4331 and is used to transport the button assembly 10 from the button assembly conveyor line 4331 to the assembly carrier 4131. The combination of the button assembly conveyor line 4331, the flipping assembly 4332, and the button assembly handling robot 4333 significantly improves the automation level of the button assembly process, simplifies operation, optimizes efficiency, and ensures the consistency and stability of assembly quality.

[0091] Optionally, such as Figure 10 As shown, the flipping assembly 4332 includes a flipping drive 43321, a transmission assembly 43322, and a flipping fixture 43323. The input end of the transmission assembly 43322 is connected to the output end of the flipping drive 43321, and the flipping fixture 43323 is connected to the output end of the transmission assembly 43322. The flipping fixture 43323 is provided with at least two centrally symmetrical first bearing grooves. One of the first bearing grooves can dock with the button feeding channel 4316, and the other first bearing groove can dock with the button assembly conveyor line 4331. Through the centrally symmetrical bearing groove structure, the flipping assembly 4332 can continuously and efficiently complete the transfer of the button assembly 10, avoid the waiting process, and improve the flipping efficiency of the button assembly 10.

[0092] Optionally, the button assembly conveyor line 4331 includes a vibrating conveyor line 43311, a pusher cylinder 43312, and a pusher rod 43313. The pusher rod 43313 is connected to the piston rod of the pusher cylinder 43312. After the button assembly 10 arrives at the flipping station, the flipping assembly 4332 drives the flipping fixture 43323 to flip. An empty flipping fixture 43323 is connected to the button feeding channel 4316. The next button assembly 10 to be flipped enters the flipping fixture 43323. Another flipping fixture 43323 is connected to the beginning of the vibrating conveyor line. The pusher cylinder 43312 is activated, and the pusher rod 43313 pushes the button assembly 10 onto the vibrating conveyor line 43311 and transports it to the multi-station assembly mechanism 410. The button assembly 10 is picked up by the button assembly handling robot 4333 and placed on the base in the assembly carrier 4131 in the multi-station assembly mechanism 410.

[0093] Optionally, such as Figure 10As shown, the flipping drive 43321 is a second flipping cylinder, and the transmission assembly 43322 includes a rack 433221 and a gear 433222. The rack 433221 is connected to the output end of the second flipping cylinder, and the gear 433222 is connected to the flipping fixture 43323. The gear 433222 and the rack 433221 are meshed together. Driven by the second flipping cylinder, the button assembly 10 can be flipped 180° to the beginning of the vibrating conveyor line 43311 by means of the meshing transmission of the gear 433222 and the rack 433221. The pusher cylinder 43312 pushes the button assembly 10 out of the flipping fixture 43323 through the pusher rod 43313, so that the button assembly 10 enters the vibrating conveyor line 43311.

[0094] Optionally, such as Figure 11 As shown, the multi-station assembly mechanism 410 includes a station divider 411 and a divider drive motor 412. The output end of the station divider 411 is connected to the station turntable 413. Multiple assembly carriers 4131 are equally spaced along the circumferential direction of the station turntable 413. The output end of the divider drive motor 412 is connected to the input end of the station divider 411. The divider drive motor 412 is used to drive the output end of the station divider 411 to rotate in the circumferential direction.

[0095] Specifically, in this embodiment, the output end of the workstation divider 411 has four workstations, which are equally divided circumferentially. Each workstation is equipped with an assembly carrier 4131. The workstation divider 411 is arranged circumferentially as follows: a pressure plate assembly workstation, a button assembly workstation, a re-pressing workstation, and a discharge workstation. The divider drive motor 412 rotates, and after being divided equally by the four workstation dividers 411, the assembly carrier 4131 carrying the base reaches the pressure plate assembly workstation. The pressure plate handling robot 422 transports the pressure plate 20 into the assembly carrier 4131. Then, the divider drive motor 412 drives the workstation divider 411 to continue rotating. Assembly carrier 4131 arrives at the button assembly station, where button assembly handling robot 4333 assembles button assembly 10 into pressure plate 20. Then, divider drive motor 412 continues to drive station divider 411 to rotate, and assembly carrier 4131 arrives at re-pressing station, where first pressing mechanism 414 presses button assembly 10 onto pressure plate 20 and corrects its position. Finally, divider drive motor 412 drives station divider 411 to rotate, and assembly carrier 4131 arrives at unloading station, where unloading robot unloads and transports button assembly 10 back to base conveyor line, where it enters the next assembly station for panel assembly.

[0096] Optionally, such as Figure 12As shown, the toggle assembly equipment also includes a continuity test assembly 435. The continuity test assembly 435 includes a test bracket 436, a pressing component 437, a toggle component 438, and a continuity detection component 439. The test bracket 436 is provided with a base carrier 131, which is used to support the base on which the toggle assembly 10 is assembled. The pressing component 437 is disposed on the test bracket 436 and is used to press against the base to fix the base in the base carrier 131. The toggle component 438 is disposed on the test bracket 436 and is used to switch the wall switch to the on or off state.

[0097] The continuity detection component 439 is mounted on the test bracket 436. The continuity detection component 439 can be electrically connected to the wall switch and determine whether the signals output by the wall switch in the on and off states are qualified. Through the continuity detection component 435, the function of the assembled wall switch can be tested to ensure that the product fully meets the design requirements in terms of on and off functions.

[0098] Optionally, the pressure assembly 437 includes a pressure cylinder 4371 and a pressure plate 4372. The pressure cylinder 4371 is connected to the test bracket 436. The low-pressure rod is set on the output end of the pressure cylinder 4371. By driving the pressure plate 4372 down through the pressure cylinder 4371, a certain pressure can be applied to the base to ensure that the base is more stable in the base carrier 131.

[0099] Optionally, the wall switch includes at least one COM terminal, at least one NC terminal, and at least one NO terminal. The continuity test assembly includes a power supply driver 4393, a first power supply component 4391, a second power supply component 4392, and a signal processing unit. In this embodiment, the signal processing unit is a PLC. The power supply driver 4393 is mounted on a test bracket. In this embodiment, the power supply driver 4393 is a double-headed cylinder. The first power supply component 4391 is connected to one output terminal of the double-headed cylinder and is located on one side of the detection limit groove. The first power supply component 4391 is provided with a first conductive pin and at least one NC test pin. The first conductive pin can contact the wall... One of the COM terminals of the switch is electrically connected, and the NC test probe can abut against the NC terminal of the wall switch; the second power supply unit 4392 is connected to the other output terminal of the double-headed cylinder and is located on the other side of the detection limit groove. The second power supply unit 4392 is provided with a second conductive pin and at least one NO test pin. The second conductive pin can be electrically connected to the other COM terminal of the wall switch, and the NO test probe can abut against the NO terminal of the wall switch; the NC test probe and the NO test probe of the signal processing unit are respectively communicatively connected to the signal processing unit. The signal processing unit is used to receive and determine whether the signals output by the wall switch in the on and off states are qualified.

[0100] Optionally, the toggle assembly 438 includes a first toggle cylinder, a first lever, a second toggle cylinder, and a second lever. The first lever is connected to the piston rod of the first toggle cylinder, and the second lever is connected to the piston rod of the second toggle cylinder. The first toggle cylinder can drive the first lever to toggle the switch to the NC on state, and the second toggle switch can drive the second lever to toggle the switch to the NO on state.

[0101] For example, the testing process will be explained by testing a double-pole, double-control wall switch:

[0102] like Figure 13 As shown, the double-pole double-control switch includes two COM terminals, two NC terminals, and two NO terminals. Correspondingly, the output terminal of the first detection drive cylinder is equipped with a first conductive pin and two NC test pins, and the output terminal of the second detection drive cylinder is equipped with a second conductive pin and two NO test pins. After the wall switch is moved into the base carrier 131, the pressing cylinder 4371 drives the pressing plate 4372 to press against the base inside the base carrier 131, fixing the base. The first toggle cylinder drives the first lever to move the switch to the NC conducting state. The first detection drive cylinder drives the first conductive pin to abut against one COM terminal, and the two NC test pins abut against the two NC terminals respectively. The COM terminal is energized, and signals are input to X0 and X2 in the PLC, which are recorded. Then, the second toggle cylinder drives the second lever to move the switch to the NO conducting state, the COM terminal is energized, and signals are input to X1 and X3 in the PLC. The functionality of the product is determined based on the results of the two energizations. It should be noted that this embodiment only illustrates the test process of a double-pole double-pole switch. The continuity test component 435 can also perform functional tests on single-pole single-control switches, single-pole double-control switches, and double-pole single-control switches. The specific test process will not be described in detail.
