A reflective solder tape copper substrate conductive point processing system for solar cell production

Abstract

The invention provides a light-reflecting welding strip copper base material electric conduction point processing system for solar energy battery piece production. The light-reflecting welding strip copper base material electric conduction point processing system comprises a hand-held rack and an actuating mechanism, and the hand-held rack is of a Y-shaped structure and is provided with the actuating mechanism. By means of the light-reflecting welding strip copper base material electric conduction point processing system for the solar energy battery piece production, the problems generally existing in welding spots in the welding process of battery pieces and welding strips that a, the positions of the welding spots are not accurate to cause the welding spots to be invalid; b, uneven structures exist on the surfaces of the welding spots to cause the electrical resistance at the welding spots to be too large in electrifying; and c, a lot of welding slag exists in the welding process tofall to the surfaces of the battery pieces, short circuit may be caused to affect use, and the like can be solved; the function of performing processing auxiliary processing on welding electric conduction points can be realized; and the light-reflecting welding strip copper base material electric conduction point processing system for the solar energy battery piece production has the advantages ofwelding point positioning assistance, welding point surface automatic polishing, welding point slag automatic cleaning and the like.

Description

technical field [0001] The invention relates to the technical field of battery production and processing, in particular to a system for processing conductive points of a copper base material of a reflective soldering tape for solar cell production. Background technique [0002] In the prior art, welding is used between the battery sheet and the welding ribbon, and the commonly used welding ribbons are divided into two types, lead soldering ribbons and lead-free soldering ribbons; manual welding is mainly used, and the quality of welding products is usually determined by the quality of the soldering points. It is determined that during the welding process, there are usually burrs, trachoma, and bubbles on the surface of the solder joints, and the burrs will have tip discharge problems. [0003] There are usually the following problems in the solder joints during the welding process of the battery sheet and the ribbon: a. The position of the solder joints is not accurate, resu...
