Abstract

The embodiment of the invention relates to the technical field of cleaning equipment, and discloses a cleaning device and a cleaning method. The cleaning device comprises a cleaning tank, a detectionoscillator and a cleaning oscillator which are located in the cleaning tank, and a controller which is connected with the detection oscillator and the cleaning oscillator; the detection oscillator isused for detecting the position of residues on the to-be-cleaned mask; and the controller is used for controlling the cleaning vibrator to clean the to-be-cleaned mask according to the position of theresidue, so that the cleaning efficiency of the mask is improved while the mask is prevented from being overwashed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of cleaning equipment, in particular to a cleaning device and a cleaning method. Background technique [0002] The mask plate needs to be cleaned before it can be used to make chips. In the conventional cleaning method, the mask is placed in the tank, which contains cleaning liquid. The tank is rectangular, and the bottom and the four side walls connected to the bottom are all flat. The bottom of the tank is placed A vibrator that can generate ultrasonic waves. The ultrasonic waves are dense and dense on the transmission path. Cavitation will occur between the dense and dense parts, and small bubbles will be generated and burst. The blasting force generated when the bubbles burst can clean the mask. . [0003] However, the inventors found that in the prior art, the cleaning time cannot be accurately adjusted for different masks, resulting in low cleaning efficiency of the mask, or...
