AI Technical Summary
Technical Problem
Tiny bubbles generated by photosensitive adhesive during solar cell manufacturing affect electrochemical performance, leading to poor electroplating and decreased electrochemical performance.
Method used
A degassing device is used, which reduces the pressure inside the containment cavity to create a vacuum environment. Combined with an ultrasonic generator to generate ultrasonic waves to create a cavitation effect, the bubbles are pushed to gather and float. The vacuum generator then removes the escaped gas, thus achieving the degassing of the photosensitive emulsion.
Benefits of technology
It effectively removes air bubbles from the photosensitive adhesive, improves the electrochemical performance of solar cells, avoids poor electroplating, and enhances product quality.

Abstract
The application relates to a defoaming device and a defoaming system. The defoaming device comprises a defoaming container, a vacuum generator and an ultrasonic generator. The defoaming container is provided with a containing cavity, the air inlet of the vacuum generator is communicated with the containing cavity, the ultrasonic generator comprises a transducing assembly and a vibrating piece, the output end of the transducing assembly and the vibrating piece are located in the containing cavity, and the vibrating piece is connected to the output end of the transducing assembly. The defoaming container of the defoaming device can contain photosensitive glue, the vacuum generator is communicated with the containing cavity of the defoaming container through the air inlet and extracts the gas in the containing cavity. The transducing assembly in the ultrasonic generator can convert electric energy into mechanical energy, the vibrating piece transmits the ultrasonic energy generated by the transducing assembly to the photosensitive glue, the ultrasonic wave generates a cavitation effect in the photosensitive glue, forms tiny bubbles, the acoustic radiation force generated by the ultrasonic wave pushes the bubbles to move and gather, accelerates the bubbles to float and escape, the vacuum generator extracts the escaped gas, and thus the photosensitive glue can be defoamed.
