Abstract

The invention relates to an automatic cracking device and an automatic cracking method of a battery piece. The automatic cracking device of the battery piece comprises a bracket, a vacuum piece suction mechanism, a gear transmission mechanism, a power driving motor and a control device. Battery piece sensors are arranged on the surfaces of left and right vacuum absorbing assemblies. The power driving motor drives the gear transmission mechanism to rotate through an output gear. The gear transmission mechanism drives the inner edges of the left and right vacuum absorbing assemblies to move up and down. The gear transmission mechanism is provided with a position sensor. The automatic cracking method comprises the steps that the control device receives a battery piece in-place signal of the battery piece sensor to control the power driving motor to start; the power driving motor drives the gear transmission mechanism to rotate to a cracking position through the output gear; the gear transmission mechanism drives the inner edges of the left and right vacuum absorbing assemblies to move up and down to crack the solar battery piece. According to the automatic cracking device and the automatic cracking method of the battery piece provided by the invention, the solar battery piece scribed by laser can be automatically cracked and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of splitting solar cells, in particular to an automatic splitting device and an automatic splitting method for solar cells. Background technique [0002] At present, in the production of solar cells, when the conversion efficiency of the cells is constant, the method of cutting the cells in half horizontally and then connecting them in series is often used to increase the power generation power of the modules. There are two processes for cutting the cell in half. One is to use laser to scribe the middle of the cell horizontally. The width and depth of the scribing line need to be precisely controlled. At present, the common splitting is manual splitting or using a manual splitting mechanism, or the control of the designed cell splitting is integrated with the control system of the entire device. Modularization has not been realized, the control cost is relatively high, and debugging is difficult. Contents ...
