Problems solved by technology

The traditional manual welding is through manual single-chip welding first, and then serial welding. There are more processes and more personnel are required. Due to the influence of manual skills, the shape and size of the battery string are unstable, and it is easy to have virtual welding, missing welding, etc. At the same time, the battery sheet is prone to cracks and fragments due to inconsistent internal stress
The shortcomings of manual welding bring great difficulties to production organization, quality control and production cost control

Abstract

The invention discloses a heat radiation type welding method and device applied to solar battery pieces. The heat radiation type welding device comprises an infrared heating device, a pressing needle device and a preheating device, the pressing needle device is placed below the infrared heating device, and the infrared heating device and the pressing needle device are arranged in the middle of the preheating device. According to the design scheme provided by the heat radiation type welding method and device, interconnecting strips can be firmly welded to main grid lines on the front faces and the back faces of the solar battery pieces, so that the heating temperature is even, the heat influence area is small, the heat radiation type welding method and device are applied to weld the fragile solar battery pieces, the breakage ratio is low, the material subfissure phenomena are fewer, and the welding quality consistency is good. Meanwhile, the welding time and temperature controllability is good, and automatic control over the welding time and the welding temperature can be achieved.

Description

technical field [0001] The invention relates to a heat radiation welding method and device applied to solar cells. Background technique [0002] The solar cell module is composed of multiple battery strings welded by bus bars and then laminated with EVA, backplane, and plexiglass plates at high temperature; the battery strings are connected into strings through the welding ribbons connected to the solar cells. In order to meet the technical requirements for increasing the output voltage of solar cells. The traditional manual welding is through manual single-chip welding first, and then serial welding. There are many processes and more personnel are required. Due to the influence of manual skills, the shape and size of the battery string are unstable, and it is easy to have false welding, missing welding, etc. At the same time, the cells are prone to cracks and fragments due to inconsistent internal stress. The shortcomings of manual welding bring great difficulties to prod...
