[0027] The utility model provides a plasma cleaning device for a liquid crystal screen. By cooperating with a movable component and a cleaning component, the plasma nozzle can be freely switched during use without timely shutdown operation, thereby ensuring the normal operation of the plasma cleaning machine and improving the cleaning efficiency of the entire production line.

[0028] Example 1

[0029] Figure 1 , Figure 2 The figure shows the overall structure of an embodiment of a plasma cleaning device for a liquid crystal screen of the utility model. Figure 1 , Figure 2 The main structure of this embodiment includes: a moving component and a cleaning component.

[0030] The moving assembly is used for horizontal displacement. Specifically, the moving assembly includes a support mounting frame 11, a first linear motor module 12 arranged on the top surface of the support mounting frame 11, a first drag chain 13 connected to the first linear motor module 12, a first slider 14 connected to the output moving end of the first linear motor module 12, a second linear motor module 15 connected to the top surface of the first slider 14, a second drag chain 16 connected to the second linear motor module 15, and a second slider 17 connected to the output end of the second linear motor module 15;

[0031] During specific use, the first linear motor module 12 drives the first slider 14 to slide. When the first slider 14 slides, the first drag chain 13 will also move. The first slider 14 drives the second linear motor module 15 to move. At this time, the second linear motor module 15 drives the second slider 17 to move, and the second slider 17 drives the curved connecting rod 21 to move, thereby driving the disc 23 to move in different directions.

[0032] The cleaning assembly is used for screen cleaning. Specifically, the cleaning assembly includes a curved connecting rod 21 connected to the second slider 17, an electric rotating shaft 22 connected to the bottom surface of the curved connecting rod 21, a disc 23 connected to the electric rotating shaft 22, a first circular hole 24 provided on the surface of the disc 23, a plasma generator 25 fitted with the first circular hole 24, a plasma nozzle 251 connected to the end of the plasma generator 25, a threaded long hole 26 provided on the side wall of the disc 23, and a second circular hole 27 and a third circular hole 28 provided on the surface of the disc 23;

[0033] During specific use, when the disc 23 moves, the plasma nozzle 251 also moves to clean the screen. When the corresponding plasma nozzle 251 is damaged, the electric shaft 22 drives the disc 23 to rotate, and the disc 23 drives the plasma nozzle 251 to rotate. In this way, the plasma nozzle 251 at other positions can be switched to the position of the screen to be cleaned. In this way, the screen cleaning can continue without stopping for maintenance.

[0034] Example 2

[0035] See also Figure 3 As shown, by setting the connection assembly, when the electric shaft 22 has a rotation failure, manual rotation switching can be achieved, further ensuring the normal cleaning operation of the plasma cleaning machine;

[0036] Specifically, it also includes a connecting assembly, which includes a first circular plate 31 fixed to the bottom surface of the electric rotating shaft 22, a circular shaft 32 fixed to the bottom surface of the first circular plate 31, and a second circular plate 33 fixed to the bottom surface of the circular shaft 32;

[0037] The connecting assembly further includes a first threaded hole 34 formed on the surface of the first circular plate 31, a second threaded hole 35 formed on the surface of the disc 23, a third threaded hole 36 formed on the surface of the second circular plate 33, and a threaded long rod 37 disposed above the first circular plate 31;

[0038] During specific use, when the electric shaft 22 is damaged, the user rotates the threaded long rod 37 in the reverse direction to disengage the threaded long rod 37 from the first threaded hole 34, the second threaded hole 35 and the third threaded hole 36 respectively. At this time, the disc 23 loses its limit, and the operator manually rotates the disc 23. When the disc 23 rotates to the required position, the user uses the threaded long rod 37 to pass through the first circular plate 31, the disc 23 and the second circular plate 33 in sequence to limit the position.

[0039] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
