Abstract

The invention relates to a tension control system device for solar cell silicon wafer cutting. The tension control system device comprises a wire turn, a fixed wheel, a spindle, a tension sensor, a lead guide wheel, a swing rod, a floating wheel, a motor and a sliding assembly; the fixed wheel is arranged on the upper portion of the spindle; the spindle is provided with a spiral groove and is wound with a diamond cutting line; the motor is mounted on the rear portion of the spindle; the tension sensor and the lead guide wheel are fixed on the sliding assembly and can slide horizontally along with the sliding assembly; the sliding assembly is arranged on the upper portion of the wire turn; the swing rod is arranged on the right side of the wire turn; one end of the swing rod is provided with the floating wheel; and the swing rod is connected with the motor on the lower portion. The tension control effect is good, the production efficiency is high, the product quality is good, and the precision is high.

Description

technical field [0001] The invention relates to a tension control system device, in particular to a tension control system device used for cutting solar cell silicon wafers. Background technique [0002] my country is now in a critical period for the development of the solar energy industry, and silicon wafer cutting plays an important role in the production and manufacturing of solar cells. [0003] With the development of the solar energy industry, our requirements for solar cells are getting higher and higher, and the thickness of silicon wafers is required to be continuously reduced. Therefore, the requirements for cutting technology are also getting higher and higher. Silicon wafers are cut using wire cutting technology, but the current wire cutting technology has problems such as difficult tension control, high cost, low production efficiency, poor product quality, and low precision. Contents of the invention [0004] The object of the present invention is to provid...
