Paper printing machine SC-PT09L/RA

for wafersfor solar cellsautomatic

The silver paste is printed to the surface of the cell by pressure, and becomes the positive and negative electrodes of the solar cell after drying and firing.

Adopt high-speed rotary DD motor, with four paper reeling tables which can quickly complete the wafer in /out and the turntable time can be less than 200ms. The squeegee head adopts the structure of direct-drive voice coil motor to realize real time pressure mode,which can realize real pressure monitoring. High precision camera alignment,the kinematics calibration algorithm with independent intellectual property rights, to achieve high-precision alignment. Automatic wet weight weighing unit, on-line printing quality monitoring (AOI) unit can be optional,to monitor the printing quality and realize loss control.
