Silicon Wafer Slicing Device

Abstract

A silicon chip separating device comprises a silicon chip separating mechanism and a feeding trough. The silicon chip separating mechanism comprises a silicon chip separating mechanism body. Two separated silicon chip conveyor belts which are parallelly and separately arranged are configured below the silicon chip separating mechanism body. The silicon chip separating mechanism body is provided with an exhausting holes which face the separated silicon chip conveyor belts. The air exhausting holes are communicated with an air exhausting device through pipeline. The silicon chip separating mechanism body is provided with rollers at positions which correspond with the front end of the conveying direction of the separated silicon chip conveyor belts. The silicon chip separating mechanism body is provided with air blowing holes of which the air blowing direction face the separated silicon chip conveyor belts. The air blowing holes are communicated with an air blower through pipeline. The feeding trough comprises a feeding trough body and a water pump. The feeding trough body is provided with an overflow opening. The overflow opening is communicated with a liquid storage trough through pipeline. The feeding trough body is internally provided with a supporting platform for placing stacked silicon chips. The supporting platform is transmissibly connected with the driving part of a vertical movement driving device. The silicon chip separating device has advantages of high silicon chip separating efficiency and small silicon chip damage in silicon chip separation.

Description

technical field [0001] The invention relates to a silicon chip slicing device, which belongs to the field of auxiliary equipment for preparing solar cells. Background technique [0002] Since the beginning of the 21st century, global energy consumption has risen sharply, and traditional fossil energy has been increasingly exhausted. Energy issues and environmental issues have gradually become two major issues of global concern. Under the pressure of sustainable development, major countries have listed the solar photovoltaic industry as the focus of the development and utilization of renewable energy. With my country becoming the second largest economy in the world, in October 2013, China's oil imports in October reached 6.3 million barrels per day, surpassing the 6.24 million barrels per day of the United States, replacing the United States as the world's largest net oil importer for the first time. In 2013, China's foreign dependence on oil and natural gas reached 58.1% an...
