At this time, the clamping assembly 200 extends from the gap between the two cleaning pressure heads 120 of the front end cleaning assembly 100, clamps the middle part of the polarizer, and pulls it back. At this time, the two cleaning pressure heads 120 of the front end cleaning assembly 100 are pressed down, and whether to open the winding wheel 110 and the spray head 140 is determined according to the need. After the clamping assembly 200 pulls the polarizer out completely from the two cleaning pressure heads 120 of the front end cleaning assembly 100, it is placed on the middle rotating feeding platform. At this time, the position of the polarizer clamped by the front end cleaning assembly 100 forms a dead angle that cannot be cleaned by the front end cleaning assembly 100. The rotating feeding platform rotates 90 degrees, rotating the cleaning dead angle caused by the clamping assembly 200 by 90 degrees. The rotating feeding platform rotates 90 degrees can make the polarizer dead angle clamped by the previous clamping assembly 200 exposed.
