The invention discloses a soldering lamp and a soldering method for a solar cell. The lamp is provided with a lamp shell of which the bottom end is provided with an opening, an infrared lamp tube which is positioned on the upper part inside the lamp shell, a plurality of soldering pressing clips and a pressing clip fixing plate for supporting the plurality of soldering pressing clips, wherein the pressing clip fixing plate is fixedly connected to a port at the bottom of the lamp shell; an opening is formed in the middle of the pressing clip fixing plate along the length direction; the plurality of soldering pressing clips are supported inside the pressing clip fixing plate in a way of vertical motion; and the bottoms of the plurality of soldering pressing clips penetrate the opening in the middle of the pressing clip fixing plate. The soldering method comprises the following steps of: arranging a solder strip on the solar cell; descending the soldering lamp; pre-pressing the solder strip on the solar cell through the soldering pressing clips; continuously descending the soldering lamp; electrifying the infrared lamp tube to give out light, and welding the solder strip and the solar cell together; and disconnecting the infrared lamp tube from a power supply and ascending the soldering lamp. The soldering lamp is simple in structure, and convenient to manufacture and use; and if the welded object is uneven, the welded object can be pressed, and the pressure is uniform.
Description
technical field [0001] The invention relates to a welding lamp used for welding solar cells and a welding pre-pressing method. In particular, it relates to a method of pressing the welding ribbon wound on the roller flatly and evenly on the welding position of the battery sheet, and using welding to ensure that the relative position between the welding ribbon and the battery sheet remains unchanged under the condition of rising temperature. A welding lamp and a welding method for welding solar cells with series / parallel welding cells. Background technique [0002] With the rapid development of the solar energy industry, the welding technology of solar cells has become an important link for the products of this industry to finally reach consumers. The effect of welding directly determines the service life and energy conversion efficiency of the cells. The preloading of the ribbon is a necessary process before welding. Welding strips are generally placed in rolls, and most o...
