Description

Technical Field

[0002] In the photovoltaic industry, laser doping of photovoltaic solar cells can reduce the series resistance of solar cells, improve photoelectric conversion efficiency, reduce surface recombination, and improve surface passivation. It has a wide range of applications in the photovoltaic industry.

[0003] Currently, most photovoltaic wafers in laser doping equipment are transported using a turntable. First, the photovoltaic wafers are loaded via a feeding conveyor line.

Detailed Implementation

[0058] Currently, most photovoltaic wafers in laser doping equipment are transported using a turntable. First, the photovoltaic wafers are loaded via a feeding conveyor line. Then, a translational vacuum suction cup moves the photovoltaic wafers from the feeding conveyor line to the photovoltaic wafer loading position on the turntable. The turntable then rotates to the processing position. After processing, the turntable rotates to the unloading position. The translational vacuum suction cup moves the photovoltaic wafers from the unloading position to the unloading conveyor line. After defect detection and scrap removal on the unloading conveyor line, the wafers are stacked on a basket.

[0059] However, existing defect detection and scrap rejection are all carried out on the unloading conveyor line, which requires an increase in the length of the unloading conveyor line. However, the increase in the length of the unloading conveyor line will increase the time that the photovoltaic cells spend running on the belt, increase the wear time between the photovoltaic cells and the belt, increase the probability of photovoltaic cell damage, reduce the yield rate, and at the same time, increase the length of the equipment, which will increase the cost of the equipment.

[0060] To address the aforementioned problems, this utility model provides a photovoltaic wafer processing equipment that can reduce the length of the loading and unloading components, thereby improving the wear and tear of photovoltaic wafers, increasing the yield rate, and also enabling the miniaturization of the photovoltaic wafer processing equipment.
