Abstract

The invention relates to laser lossless cutting equipment and process for a photovoltaic cell. The equipment comprises a rack, the rack is provided with a first material conveying mechanism used for feeding, a cutting mechanism used for cutting the photovoltaic cell, a conveying mechanism used for conveying the photovoltaic cell and a second material conveying mechanism used for discharging, and the conveying mechanism is located between the first material conveying mechanism and the second material conveying mechanism; the cutting mechanism comprises a cutting laser used for cutting the photovoltaic cell, a heating laser used for heating the photovoltaic cell and a cooling assembly used for cooling the photovoltaic cell, all of which are sequentially arranged in the conveying direction ofthe photovoltaic cell. The two sides of the photovoltaic cell piece are cut by the cutting laser device, and the heating laser device heats a connecting line area between two cutting marks, so that the photovoltaic cell piece is cut. The equipment and the process have the effects of being high in automation degree, convenient and fast to feed and discharge, high in photovoltaic cell cutting quality and high in machining efficiency.

Description

technical field [0001] The invention relates to the technical field of photovoltaic battery sheet processing, in particular to a laser non-destructive cutting equipment and process for photovoltaic battery sheets. Background technique [0002] Photovoltaic cells are used to convert the sun's light energy into electricity. At present, silicon solar cells based on silicon are widely used in terrestrial photovoltaic systems, which can be divided into monocrystalline silicon, polycrystalline silicon and amorphous silicon solar cells. During the use of the photovoltaic cell, in order to improve the flexibility and performance of the photovoltaic cell, it is necessary to cut the photovoltaic cell. Then, the cut photovoltaic cells are connected in series and parallel to form photovoltaic modules of different sizes for application. [0003] In the existing related technologies, a laser cutter is usually used to cut photovoltaic cell sheets. This cutting method is likely to cause a...
