Double-layer buffer welding mechanism for solar wafer module welding

Abstract

The invention discloses a double-layer buffer welding mechanism for solar wafer module welding. The double-layer buffer welding mechanism comprises a bottom plate and a clamping block, wherein an upper limiting block and a lower limiting block are respectively arranged on the upper part and the lower part of a linear sliding rail; one end of the clamping block is arranged on the linear sliding rail in a sliding manner, and a welding gun is fixedly arranged at the other end of the clamping block; a first buffer spring and a supporting block are respectively arranged between the clamping block and the upper limiting block and the lower limiting block; a driving device used for driving the clamping block to move is arranged on the clamping block; a clamping plate is fixedly arranged on a sideface of a connecting plate; and a steel wire for holding the grid line is arranged at the lower end of the clamping plate. According to the arrangement of the steel wire and the second buffer spring,the grid line is held by the steel wire in the welding process, the holding grid is reinforced by the second buffer spring, and each welding spot can be held. Due to the arrangement of the first buffer spring, upper and lower spots of each welding gun are reinforced, each welding spot can be welded, the probability of insufficient solder and missing solder can be effectively reduced, and the welding quality is improved.

Description

technical field [0001] The invention relates to the technical field of solar module welding equipment, in particular to a double-layer buffer welding mechanism for solar wafer component welding. Background technique [0002] In recent years, with the rapid development of the photovoltaic industry, the production of solar modules has been greatly promoted. In the production process of solar modules, the welding of solar modules has become a key process in the whole production process, and the quality and efficiency of welding directly affect the reliability of solar modules. [0003] In the current solar module welding technology, there are still the following obvious defects: 1. The contact state between each solder joint and the welding head is inconsistent, resulting in virtual welding and over welding; 2. The grid line is easy to affect the position of the solder joint, making each solder joint The position of the point is not uniform, which affects the welding quality. ...
