[0032] However, the spindle 3 is composed of the sleeve 301, the center shaft 302 and the slip ring base 303, the sleeve 301 is arranged on the adapter plate 2 and fixed, the center shaft 302 is inserted into the sleeve 301, and the center shaft 302 is synchronously driven with the spindle motor 4 through the synchronous belt 5. The spindle 3 is mainly used for placing the panel 19, and the height and rotation angle of the panel 19 are adjusted by controlling the spindle 3.

[0033] One side of the lifting plate 1 is provided with the lifting cylinder 10 connected with the adapter plate 2, the lifting cylinder 10 is used for controlling the lifting and moving of the adapter plate 2 on the lifting plate 1, the extension operation of the lifting cylinder 10 can effectively control the moving of the adapter plate 2 on the lifting plate 1, and the height adjustment effect is achieved.

[0034] In addition, when the spindle 3 is controlled to rotate through the synchronous belt 5, the first synchronous wheel 15 is arranged at the output end of the spindle motor 4, the second synchronous wheel 16 is sleeved outside the center shaft 302, the synchronous belt 5 is connected with and surrounds the first synchronous wheel 15 and the second synchronous wheel 16, and the first synchronous wheel 15 and the second synchronous wheel 16 are synchronously driven. At this time, the spindle motor 4 can rotate in different directions, so that the rotating direction of the spindle 3 is changed.

[0035] When the spindle 3 rotates, in the technical solution, the inductive effect between the inductor 17 and the inductive sheet 18 is used to ensure that the two do not separate. Specifically, the inductor 17 is arranged on the adapter plate 2, the inductive sheet 18 is sleeved outside the center shaft 302 and is used for controlling the rotation angle of the center shaft 302. The inductor 17 is in U shape, the inductive sheet 18 rotates in the opening of the inductor 17 and performs rapid rotation.

[0036] Regarding the structure of the spindle 3, the sleeve 301 is arranged on the adapter plate 2 and fixed, the center shaft 302 is inserted into the sleeve 301, the slip ring base 303 is connected with the bottom of the center shaft 302, and the protruding portion 3021 is arranged at the top of the center shaft 302 and clamped on the top of the sleeve 301.

[0037] The top of the center shaft 302 is provided with a linkage cleaning disc 8 when the cleaning disc 9 is installed. The cleaning disc 8 is provided with four adsorption grooves 9 for placing the panel 19. The bottom of the adsorption groove 9 is communicated with the vacuum air duct 6 one by one.
