In the process of fixing the TFT glass plate 10, a brake bar spring 305 is fixedly arranged between the brake bar 401 and the support bar guide hole 304. By pulling the movable locking frame 4 with force, the brake bar 401 on the movable locking frame 4 slides inside the support bar guide hole 304 to increase the distance between the fixed locking frame 3 and the movable locking frame 4. Then, the two ends of the TFT glass plate 10 are clamped inside the TFT glass plate clamping slot 303. After releasing the hand, the TFT glass plate 10 can be fixed. The TFT glass plate 10 is fixed on the card strip 301, and the distance between the fixed lock frame 3 and the movable lock frame 4 is changed by pulling the movable lock frame 4, so as to improve the scope of use and the flexibility of use. The rotation angle range of the rotating motor 2 is 0-180°, and the rotation angle range of the rotating motor 2 is 0-180°, so that the TFT glass plate 10 can be circulated inside the cleaning box 1. When the rotating motor 2 rotates, the TFT glass plate 10 is driven by the fixed lock frame 3 to be beaten on the semi-aqueous cleaning agent 11 to achieve the purpose of cleaning, and the dust and other impurities on the surface of the TFT glass plate 10 are removed by beating; At the same time, in addition to removing dust from the TFT glass plate 10 by beating, a cold air inlet 101 connected to the inside of the cleaning box 1 is opened on one side of the cleaning box 1, and the cold air inlet 101 is connected to the high-pressure air pump 5 through the first connecting pipe 501.

This form of water-gas mixture is called a two-fluid. The tiny bubbles quickly burst when they come into contact with the TFT glass plate 10, and will form an impact force on the surface of the TFT glass plate 10, thereby knocking off the more stubborn particles on the surface and flushing them away with the high-pressure fluid.
