[0002] A touch switch is an electronic switch that is usually used to control the power on and off of electronic devices. It usually consists of one or more triggers, which are switched on and off by gently pressing the trigger. Compared with traditional mechanical switches, this switch is lighter and easier to operate, and only requires slight pressure to trigger. The principle of a touch switch is usually based on capacitance, pressure or other sensing mechanisms. When the user touches the switch, the trigger senses this action and sends a signal to the corresponding circuit to start or shut down the device. This switch is commonly used in various electronic devices, such as smartphones, tablets, electronic game controllers, etc. In the prior art:

[0054] like Figure 1~Figure 5 As shown, in an embodiment of the utility model, a touch switch automatic unloading device is provided, comprising:

[0055] A carrier 1, wherein a discharge passage 11 connected to the top and the bottom is provided inside the carrier 1, a socket 122 is provided on at least one side wall of the carrier 1, and a guide slot 121 vertically connected to the discharge passage 11 is formed inside the carrier 1 by extension of the socket 122;

[0056] The stop bar 2 is movably inserted into the guide slot 121 from the socket 122, a guide pin 21 is provided at one end of the stop bar 2 that does not extend into the guide slot 121, the axial direction of the guide pin 21 is perpendicular to the direction in which the stop bar 2 extends into the guide slot 121, and the stop bar 2 is provided with a discharge slot 22 that is arranged in the same direction as the discharge channel 11;

[0057] The lifting block 3 is provided with a punch bar 31 and a push-pull member 32, wherein the punch bar 31 is arranged directly above the discharge channel 11, and the push-pull member 32 is provided with a ramp guide groove 321 into which the guide pin 21 is inserted; and

[0058] The unloading cylinder 4 drives the lifting block 3 to move up and down.

[0059] In this solution, after the assembly of the touch switch 5 in the carrier 1 reaches the last riveting step, the station switching plate 6 transfers the carrier 1 from the riveting station 66 to the unloading station 61. By driving the lifting block 3 to lift and lower, the push-pull member 32 is driven to lift and lower. When the push-pull member 32 descends, the inclined wall of the ramp guide groove 321 squeezes and pushes the guide pin 21, thereby pushing the stop bar 2 inward. Conversely, the rise of the lifting block 3 pulls the stop bar 2 outward. When the stop bar 2 is pushed and inserted into the guide slide groove 121 to a predetermined position, the unloading groove 22 of the stop bar 2 is aligned and connected with the unloading channel 11 of the carrier 1, so that the finished touch switch 5 located at the top of the unloading channel 11, i.e., the loading groove 111, can be unloaded through the unloading channel 11 that is aligned and connected with the unloading groove 22, and at the same time, the punch bar 31 can exert a certain impact force on the finished touch switch 5, so that the finished touch switch 5 is easier to rush through the unloading channel 11. The automatic unloading of the touch switch 5 of the prior art such as document 1 during the assembly production process is realized.

[0060] In one embodiment, an inner wall surface of the guide slot 121 is provided with a first magnetic attraction member close to the socket 122, and an outer wall surface of the stop bar 2 is provided with a second magnetic attraction member matching the first magnetic attraction member; the guide slot 121 is a blind slot;

[0061] When the second magnetic attraction member is attracted to the first magnetic attraction member, the discharge groove 22 and the discharge channel 11 are displaced from each other;

[0062] When the stop bar 2 abuts against the bottom of the guide slot 121, the second magnetic member is separated from the first magnetic member, and the discharge slot 22 is aligned and connected with the discharge channel 11. Specifically, the second magnetic member is attracted to the first magnetic member, ensuring that the stop bar 2 can reach the predetermined position when it is pulled out of the guide slot 121, so that the guide pin 21 can normally fit into the ramp guide slot 321 of the push-pull member 32 when the lifting block 3 descends next time, effectively avoiding jamming. In detail, when the lifting block 3 descends, the inclined guide groove 321 of the push-pull member 32 is inserted into the guide pin 21, and by pushing the guide pin 21 to slide in the inclined guide groove 321, the second magnetic member is separated from the first magnetic member, and the guide pin 21 continues to be pushed, thereby pushing the stop bar 2 further into the guide slide groove 121, until the stop bar 2 hits the bottom of the guide slide groove 121, the unloading groove 22 and the unloading channel 11 are just connected in position, and the punch bar 31 can be inserted into the unloading channel 11 at this time, and then the finished touch switch 5 at the top of the unloading channel 11 is punched out from the bottom of the unloading channel 11 to realize unloading. When the lifting block 3 rises, the guide pin 21 can be pulled by the action of the ramp guide groove 321, so that the stop bar 2 is pulled out of the ramp guide groove 321 by a predetermined distance, until the guide pin 21 slides to the guide opening 3211 of the ramp guide groove 321, and the second magnetic attraction member just slides to the position of the first magnetic attraction member and re-engages, and the lifting block 3 continues to rise, and the guide pin 21 is disengaged from the guide opening 3211 of the ramp guide groove 321. Optionally, the guide slot 121 can also be set as a through slot. When it is set as a through slot, it is necessary to set a limiter to limit the deepest distance or optimal position of the stop bar 2 extending into the guide slot 121.

[0063] In another embodiment, the push-pull member 32 is further provided with a straight guide groove 322 connected to the ramp guide groove 321, and the arrangement direction of the straight guide groove 322 is consistent with the discharge channel 11. Specifically, the straight guide groove 322 is connected to the end of the ramp guide groove 321 away from the guide opening 3211. The ramp guide groove 321 ensures that the stop bar 2 is pushed into the guide slide groove 121, so that the discharge channel 22 and the discharge channel 11 are aligned and connected. After the straight guide groove 322 enables the discharge channel 22 to be aligned and connected with the discharge channel 11 and maintains the connection, the punch bar 31 can continue to extend downward into the discharge channel 11, so as to more easily punch the finished touch switch 5 in the discharge channel 11 out of the discharge channel 11, further improving the degree of automation and adequacy of discharge.

[0064] In another embodiment, the discharge channel 11 includes a loading trough 111 located at the upper end of the guide chute 121 and a discharge channel 112 located at the lower end of the guide chute 121, and the notch of the discharge channel 112 is larger than the notch of the loading trough 111, so as to ensure that the punch bar 31 punches the finished touch switch 5 in the loading trough 111 through the discharge slot 22 of the stop bar 2 until entering the discharge channel 112, so that the finished touch switch 5 can roll freely in the discharge channel 112. Specifically, it is ensured that the finished touch switch 5 passes through the discharge channel 112 smoothly for discharge to avoid jamming.

[0065] In another embodiment, a key position avoidance opening 311 is provided at the end of the punch bar 31. Specifically, by providing the key position avoidance opening 311, it is prevented that the punch bar 31 directly hits the key position of the touch switch 5 to cause damage to the touch switch 5 or poor contact.

[0066] In another embodiment, a guide opening 3211 is provided at the end of the ramp guide groove 321. When the second magnetic attraction member is attracted to the first magnetic attraction member, the guide opening 3211 is directly opposite to the guide pin 21, so as to ensure that when the lifting block 3 drives the push-pull member 32 to descend, the guide pin 21 can just fit into the guide opening 3211 and then be inserted into the ramp guide groove 321. Thus, the coordination between the components is improved, jamming is further avoided, and stable pushing and pulling of the gear bar 2 is ensured.

[0067] Detailed, such as Figure 2 and Figure 4 As shown, the guide opening 3211 is directly opposite to the guide pin 21. When the push-pull member 32 descends, the guide pin 21 is inserted into the ramp guide groove 321 from the guide opening 3211. During the process, the inclined wall of the ramp guide groove 321 squeezes and pushes the guide pin 21, thereby pushing the stop bar 2 inward; until Figure 1 As shown, the guide pin 21 slides to the end of the inclined guide groove 321. At this time, the discharge groove 22 of the stop bar 2 is aligned with the discharge channel 11 of the carrier 1. The end of the punch bar 31 is just adjacent to the loading groove 111 at the top of the discharge channel 11, and is close to the finished product of the touch switch 5 located in the loading groove 111; the lifting block 3 drives the punch bar 31 and the push-pull member 32 to continue to descend. At this time, the guide pin 21 slides in the straight guide groove 322 until it is as shown in FIG. Figure 3 As shown, the punch bar 31 is inserted into the discharge channel 11 and punches out the finished product of the touch switch 5, and the finished product of the touch switch 5 falls into the discharge through hole 601 of the station switching plate 6 and finally falls into the discharge bin 67 below. On the contrary, the lifting block 3 rises, driving the punch bar 31 and the push-pull member 32 to rise, the stop bar 2 extends from the guide slide groove 121 and resets, and the discharge through groove 22 of the stop bar 2 and the discharge channel 11 of the carrier 1 are misaligned, so that the loading groove 111 at the top of the discharge channel 11 can be re-placed with new accessories and the next finished product of the touch switch 5 can be assembled.

[0068] In another embodiment, the outer surface of the first magnetic member is flush with and smoothly transitions to an inner wall surface of the guide slot 121, and the second magnetic member is flush with and smoothly transitions to the outer wall surface of the stop bar 2. Specifically, while ensuring a certain magnetic positioning, it will not affect the movement of the stop bar 2 in the guide slot 121, avoiding motion interference.

[0069] In another embodiment, a third magnetic member is disposed at one end of the guide pin 21 close to the push-pull member 32, and a fourth magnetic member is disposed on the ramp guide groove 321 adjacent to the guide opening 3211 and matching the third magnetic member. Specifically, the first to fourth magnetic members are all magnets.

[0070] In another embodiment, an elastic member is further included, and the elastic member is arranged at one end of the stop bar 2 away from the guide pin 21 or the elastic member is arranged at one end of the guide slot 121 away from the socket 122. Specifically, by arranging the elastic member, the alignment fault tolerance and the resetting ability of the stop bar 2 are improved. The elastic member can be a compression spring.
