Laser half-cutting machine for crystal silicon solar battery cell

Abstract

The invention provides a laser half-cutting machine for a crystal silicon solar battery cell. The laser half-cutting machine for the crystal silicon solar battery cell comprises a case, a laser scanning system, two machining tables and two rotation conveying devices. A working table plate is arranged on the top part of the case; the laser scanning system is arranged on the working table plate; the two machining tables are arranged in parallel and are arranged on the working table plate at an interval; the two rotation conveying devices are arranged on the working table plate; each rotation conveying device comprises a rotation driving device and two mechanical arms; each rotation driving device is fixed to one side of the corresponding machining table; one ends of the two mechanical arms are fixedly connected with driving ends; a taking-out sucking disc is fixed to the other end of one mechanical arm; a fission sucking disc module is fixed to the other end of the other mechanical arm; each rotation driving device drives the two mechanical arms to rotate, so that each taking-out sucking disc and each fission sucking disc module move to positions above the corresponding machining table. The laser half-cutting machine for the crystal silicon solar battery cell has the advantages of convenience in use, high machining efficiency due to continuous machining, and capability of avoiding damage on an anti-reflection film on the front face of the battery cell during a cell breaking process.

Description

technical field [0001] The invention relates to the technical field of solar cell processing, in particular to a laser half-cutting machine for crystalline silicon solar cells. Background technique [0002] At present, photovoltaic solar crystalline silicon cells have developed into the mainstream of green new energy, and the photovoltaic industry has reached a large scale. Improving the power generation efficiency of crystalline silicon cells has become the goal pursued by the industry. The main specifications and dimensions of the existing crystalline silicon cells are: polycrystalline cells 156mm×156mm, or single crystal cells 156mm×156mm, the new process requires the shape of the existing cells to be divided, such as polycrystalline cells, Single crystal cell 156mm×156mm is divided into 156mm×78mm. Divide into two, and then perform serial welding, which can improve the power generation efficiency of the module. The division process is divided into two steps. One is to ...
