Amorphous silicon film solar battery laser scribing device and work-piece holder thereof

The utility model discloses an amorphous silicon film solar battery laser scribing device and a work-piece holder thereof, which is used to actuate laser scribing on amorphous silicon (a-Si) or/and rear electrodes of amorphous silicon film solar batteries . A Y-axis mount of the laser scribing device is mounted above an engine base via a vertical column, a Y-axis motion system is installed under the Y-axis mount, and the work-piece holder is mounted below the Y-axis motion system in suspending form, thereby bringing convenience for installing an automatic feeding and discharging system and increasing the automation and producing efficiency of the device. Besides, a CCD locating system transmits collected locating data to a computer industry-control system, the computer industry-control system controls deviation-rectifying adjustment locating points of the work-piece holder, thereby realizing high degree of automation and fine scribing quality.
