[0002] In the existing solar cell multi-busbar series welding process, the light box uses infrared lamps to heat up instantaneously, and the air cylinder is lifted up and down, and the top fan continuously blows hot air to the surface of the battery sheet and the ribbon. The existing light box cannot be heated with the battery. The solar panels form a relatively airtight cavity. However, in order to achieve the effect of multi-busbar series welding of solar cells, it is necessary to ensure that the temperature difference of the solar cells in the effective heating area of ​​the light box is controlled within 3°C, so as to reduce the false welding and over-welding of the ribbon and the solar cells.

Abstract

The invention discloses a welding lamp box. The welding lamp box comprises a lifting assembly and a heating box body assembly. The lifting assembly is fixedly connected with the heating box body assembly and used for driving the heating box body assembly to move up and down. The heating box body assembly comprises an infrared temperature sensor, a fan, an infrared lamp tube and a box body; openings are formed in the upper side and the lower side of the box body, and the box body is used for covering a workpiece; the infrared lamp tube is fixed in the box body, the fan is fixed at an opening in the upper side of the box body, and the infrared lamp tube and the fan are matched for heating and welding; and the infrared temperature sensor is fixed in the box body and is used for monitoring the temperature of the infrared tube.

Description

technical field [0001] The invention relates to the technical field of solar cell welding, in particular to a welding light box. Background technique [0002] In the existing multi-busbar string welding process for battery cells, the light box uses infrared lamps to heat up instantly, and the air cylinder rises and falls up and down, and the top fan continuously blows hot air to the surface of the battery cells and the welding strip. The existing light box cannot be heated with the battery. However, in order to achieve the effect of multi-busbar string welding of cells, it is necessary to ensure that the temperature difference of the cells in the heating effective area of ​​the light box is controlled within 3°C, thereby reducing the virtual welding and over-welding between the ribbon and the cells. and so on bad. [0003] Therefore, designing a light box with a uniform heating temperature during welding has become an urgent problem to be solved. SUMMARY OF THE INVENTION ...
