[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0017] Reference Figures 1-4 As shown, this embodiment of the utility model provides a cleaning mechanism for the contact area of ​​a dome switch, comprising: Frame size 100; Lateral movement component 200; The base plate 300 is slidably connected to the frame 100 via the lateral movement component 200; the lateral movement component 200 drives the base plate 300 to move laterally. The take-up assembly 400 includes a power unit 410 and a take-up roll 420 rotatably connected to the front of the base plate 300; the output end of the power unit 410 is connected to the take-up roll 420 to drive the take-up roll 420 to rotate. The pulley assembly 500 includes a lifting component 510 and a pulley 520 connected to the lifting component 510; the lifting component 510 drives the pulley 520 to slide up and down on the bottom of the base plate 300. The feeding assembly 600 includes a feeding roll 610 rotatably connected to the front of the base plate 300; a dust-free belt 620 is wound around the feeding roll 610, and one end of the dust-free belt 620 is wound around the take-up roll 420 after passing through the pulley 520.

[0018] Turntable 800 is located on one side of frame 100 and can rotate on its own.

[0019] Multiple products 900 to be cleaned are spaced apart on the turntable 800.

[0020] Specifically, in this embodiment, the unloading roll 610 releases the cleanroom belt 620, which then passes through the pulley 520 and is received into the take-up roll 420. The lateral movement component 200 drives the base plate 300 and the cleanroom belt 620, take-up roll 420, and unloading roll 610 connected to the base plate 300 to move laterally, thereby laterally wiping the product 900 to be cleaned on the turntable 800 (the product 900 to be cleaned is equipped with a dome switch). In addition, the up and down movement of the pulley 520 realizes the switching of the product 900 to be cleaned, thereby realizing fully automatic cleaning of the product, improving the cleaning effect and efficiency, avoiding secondary pollution and damage, thereby improving the product yield and reliability; improving production efficiency and automation; ensuring cleaning consistency and stability; and reducing production costs.

[0021] When the dome switch of the product 900 to be cleaned on the turntable 800 is turned below the pulley 520, the lifting component 510 drives the pulley 520 to descend until it contacts the dome switch. Then, the lateral movement component 200 drives the base plate 300 to move laterally to wipe the dome switch. After wiping, the lifting component 510 drives the pulley 520 to rise and reset (at this time, the turntable 800 rotates so that the next product 900 to be cleaned moves to the bottom of the pulley 520).

[0022] Furthermore, this application also includes a plurality of guide wheels 700, which are rotatably connected to the front side of the base plate 300; at least one guide wheel 700 is provided between the pulley 520 and the take-up roll 420; at least one guide wheel 700 is provided between the pulley 520 and the unwind roll 610.

[0023] Specifically, the guide wheel 700 in this embodiment can tension the cleanroom belt 620, thereby preventing the cleanroom belt 620 from becoming loose and affecting its transmission.

[0024] In some embodiments, the lateral movement component 200 is a moving module, and the slider of the moving module is connected to the back of the base plate 300.

[0025] In some embodiments, the lifting component 510 is a cylinder.

[0026] Furthermore, this application also includes two first limit sensors 210, which are used to monitor the two extreme positions of the lateral movement of the base plate 300.

[0027] Specifically, this embodiment can monitor the limit position of the lateral movement of the base plate 300 to prevent the base plate 300 from moving beyond its travel range.

[0028] Furthermore, this application also includes a first sensor 630 disposed on one side of the unloading roll 610, the first sensor 630 being used to identify whether the unloading roll 610 is wrapped with a dust-free belt 620.

[0029] Specifically, this embodiment can identify whether there is a dust-free belt 620 on the unloading roll 610, thereby providing timely feedback and replacing the unloading roll 610.

[0030] Furthermore, this application also includes a second sensor 640 disposed on one side of the base plate 300. The second sensor 640 includes a transmitter and a receiver, and the cleanroom belt 620 is disposed between the transmitter and the receiver. The second sensor 640 is used to monitor whether the cleanroom belt 620 is disconnected.

[0031] Specifically, this embodiment can determine whether the cleanroom belt 620 is disconnected through the transmitter and receiver, and thus provide timely feedback to perform shutdown actions, etc.

[0032] Furthermore, this application also includes a third sensor 530 disposed on the lifting component 510, the third sensor 530 being used to monitor the lifting stroke of the pulley 520.

[0033] Specifically, this embodiment can monitor the lifting stroke of the pulley 520 to prevent the pulley 520 from overtraveling and damaging the item to be cleaned.

[0034] Furthermore, the unloading assembly 600 also includes a damper 650 connected to the unloading roll 610.

[0035] Specifically, the damper 650 in this embodiment is mainly used to adjust the tension, speed or inertia during the unwinding process to ensure that the dust-free belt 620 is released smoothly, without vibration or slack.

[0036] Furthermore, this application also includes a control unit, which is electrically connected to the power unit 410, the lateral movement assembly 200, and the lifting component 510.

[0037] Specifically, in this embodiment, the power unit 410, the lateral movement component 200, and the lifting component 510 can be controlled by the control unit to achieve automation and further improve efficiency.

[0038] Furthermore, in the case of including the first limit sensor 210, the first sensor 630, the second sensor 640, and the third sensor 530: The control unit is electrically connected to the first limit sensor 210, the first sensor 630, the second sensor 640, and the third sensor 530.

[0039] Specifically, in this embodiment, the first limit sensor 210, the first sensor 630, the second sensor 640, and the third sensor 530 can all output the received signals to the control unit. The control unit controls the lifting component 510 and the lateral movement component 200 based on the received signals. For example, when the first limit sensor 210 detects that the bottom plate 300 has moved beyond its travel range, it can control the lateral movement component 200 to stop or change its movement direction. Similarly, when the second sensor 640 detects that the dust-free cleaning unit has been disconnected, it can control the power unit 410 to stop, preventing the take-up roll 420 from running idle.

[0040] Furthermore, the pulley assembly 500 also includes a connecting seat 540 and a slider 550; the connecting seat 540 includes a first connecting member and a second connecting member that are vertically connected; the pulley 520 is rotatably connected to the bottom end of the first connecting member, and the output end of the lifting component 510 is connected to the top of the first connecting member; a groove 560 is provided on the inner side of the second connecting member; the slider 550 is located on one side of the lifting component 510; the groove 560 cooperates with the slider 550.

[0041] Specifically, the connecting seat 540 in this embodiment can connect the output end of the lifting component 510 to the pulley 520, and at the same time can provide guidance for the up and down lifting of the pulley 520.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
