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

During assembly, the spring 12 needs to be placed in the mounting hole first, and then the push rod 13 is assembled at the upper end opening of the mounting hole, and a certain pressure is applied to the push rod 13 to make the push rod 13 interference connected 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 transporting assembly 433, wherein the button assembly mechanism 431 is used to assemble the buttons, springs 12 and pressure rods 13 constituting the button assembly 10, and the button transporting assembly 433 is used to transport the assembled button assembly 10 to the pressing plate 20.

The push rod discharge nozzle 43122 and the push rod discharge pipe 43121 are connected to the push rod discharge nozzle 43122, and at least one push rod 13 is stored in the push rod discharge pipe 43121; the button body conveying line 4313 is used to convey the button body 11 to the bottom of the spring discharge nozzle 43112 and the bottom of the push rod discharge nozzle 43122 in sequence, the spring discharge pipe 43111 and the push rod discharge pipe 43121 can be connected to the air source respectively, and the air source blows the spring 12 and the push rod 13 into the button body 11 in sequence, thereby preparing for subsequent pressing.

[0078] The air source in this embodiment can be an air pump, which is connected to the spring discharge pipe 43111 and the push rod discharge pipe 43121 through a main air pipe and two branch pipes. 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 respectively connected to a branch pipe, and the 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.

During assembly, after the button body 11 reaches the spring assembly position in the button body conveying 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 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. In order to ensure the lubricity of the spring and avoid jamming of the spring movement, an oiling station is provided between the button assembly station and the push rod assembly station. The oiling station is provided with a button oiling component 434. The button oiling component 434 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 runs to the 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 runs to the end position (the piston rod of the second lifting cylinder 43123 extends), the push rod discharge nozzle 43122 presses the button body 11, and 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, a first spiral section 431111 is provided in the middle of the spring discharge tube 43111 to prevent the spring in the spring discharge tube 43111 from falling from the spring discharge nozzle 43112 without the driving of air pressure, so that the spring is temporarily stored in the spring discharge tube 43111. Similarly, a second spiral section 431211 is provided in the middle of the ejector discharge tube 43121 to prevent the ejector in the ejector discharge tube 43121 from falling from the ejector discharge nozzle 43122 without the driving of air pressure, so that the ejector 13 is temporarily stored in the ejector discharge tube 43121.

[0081] Alternatively, if Figure 7As shown, the spring feeding assembly 4311 also includes a spring feeding tube 43115, a first feeding drive component 43117, a first feeding needle 43116, a second feeding drive component 43119 and a second feeding needle 43118. The spring feeding tube 43115 is connected to the spring discharge tube 43111. The first feeding drive component 43117 is arranged at the connection between the spring feeding tube 43115 and the spring discharge tube 43111. The first feeding needle 43116 is connected to the output end of the first feeding drive component 43117. The second feeding drive component 43119 is arranged above the first feeding drive component 43117.

During material distribution, the spring 12 enters the spring delivery tube 43115 through the spring vibration plate and the spring direct vibration channel. When multiple springs 12 are moved in sequence to the intersection of the spring delivery tube 43115 and the spring discharge tube 43111, the second spring material distribution cylinder runs to the origin, the second material distribution needle 43118 retracts, the first material distribution needle 43116 extends, and the first spring is stopped; then, the second spring material distribution runs 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 tube 43111, and the spring is discharged. The first spiral section 431111 on the tube 43111 ensures that the spring will not fall from the spring discharge nozzle 43112; when the button body 11 runs along the button body conveyor line 4313 to the bottom of the spring discharge nozzle 43112, the first lifting cylinder 43113 drives the spring discharge nozzle 43112 to abut against the button body 11, and the spring discharge nozzle 43112 is aligned with the assembly hole. After receiving the assembly signal, compressed air enters the spring discharge tube 43111, and the spring 12 quickly enters the assembly hole of the button body 11 under the push of compressed air to complete the spring assembly.

After the button body 11 turns, the button body 11 is driven by the button material transfer assembly 4317 to move along the button material transfer channel 4316. The button material transfer assembly 4317 can move the button body 11 to the bottom of the spring discharge nozzle 43112 and the bottom of the push rod discharge nozzle 43122 in turn to assemble the spring 12 and the push rod 13.

[0084] Alternatively, if Figure 8 As shown, the button turning assembly 4315 includes a turning cylinder 43151 and a turning jig 43152. The turning jig 43152 is connected to the output end of the turning cylinder 43151. The turning jig 43152 can be rotated to a preset angle by driving the turning cylinder 43151. In this embodiment, the button straight vibration channel 4314 is perpendicular to the button material selection channel 4316.
