A device for breaking solar cells

Abstract

The invention discloses a piece breaking device of a solar cell piece. The piece breaking device comprises a conveying belt and is characterized in that a positioning press assembly and a piece breaking assembly are arranged on the conveying belt, wherein the positioning press assembly comprises a rotary positioning roller, the cross section of the positioning roller is a cam cross section, the piece breaking assembly comprises an installation late, a swinging rod, a crank, a rotation shaft, a sliding block and a fixed block, a groove with a downward opening is formed in a lower part of the installation plate, an outer end of the crank is hinged with one end of a connection rod, the other end of the connection rod is hinged with an upper end of the sliding block, a limitation groove is transversely formed in the sliding block, a first roller is arranged at one end of the swinging rod and is limited in the limitation groove, the other end of the swinging rod is arranged on the rotationshaft, cams are arranged on the rotation shaft and are longitudinally and symmetrically arranged, a sliding groove is formed in an upper side surface of the installation block, a piece breaking rod isarranged in the sliding groove in a sliding way, a second roller is arranged at an upper end of the piece breaking rod and is in contact with lower ends of the cams, a spring is arranged in the fixedblock, and piece breaking strip is transversely arranged at a lower end of the piece breaking rod.

Description

technical field [0001] The invention relates to a chip breaking device, in particular to a solar cell chip breaking device. Background technique [0002] Solar cells are an important part of solar photovoltaic modules. In the production process of solar modules, especially small solar modules, it is necessary to cut the entire solar cells into small pieces of solar cells. The generally adopted processing method is to first use a laser machine to laser cut the entire solar battery sheet to form laser traces with a certain depth on the entire solar battery sheet. In the process of laser cutting, the solar cells are not directly cut off, the reason is that the whole solar cell is placed on the platform for laser cutting, if it is cut directly, it will cause damage to the platform, so, in order to get a piece of small For solar cells, an additional process of picking the solar cells is required, so that the solar cells can be broken along the laser traces. At present, manual o...
