Description

Technical Field

[0001] The present application belongs to the technical field of tray cleaning, and in particular relates to a chip tray cleaning device. Background Art

[0002] During the CIS (CMOS Image Sensor) chip testing process, the chip surface needs to be wiped to remove dirt on the surface in order to improve the chip test yield. Currently, the chip surface is mainly wiped and cleaned manually using a dust-free cloth dipped in alcohol, which not only has low cleaning efficiency, but also has large differences in cleaning effects.

[0003] For example, the chip cleaning device and chip cleaning equipment provided by patent CN217289438U include a transmission mechanism, a discharge mechanism and a wiping mechanism. The transmission mechanism is used to transmit a tray loaded with chips. The discharge mechanism is arranged above the transmission mechanism and is used to release and rewind the dust-free cloth in the direction of the transmission mechanism. The wiping mechanism is used to drive the dust-free cloth released by the discharge mechanism to abut against and wipe the chips on the tray transmitted by the transmission mechanism. However, the cleaning part in the above patent does not have a partition component during cleaning, which makes it easy for other impurities to affect other chips during cleaning. At the same time, only a single cleaning is performed, and all dust and impurities cannot be effectively removed. Utility Model Content
