Embodiment Construction

[0006] Typical embodiment: the typical application of the present invention is to weld solar cells. The common specifications have two types of side lengths of 125 mm and side lengths of 156 mm. On each cell sheet, there are generally 3 busbars (there are also 2 or 4 busbars). belt), the layout position of the confluence belt is generally to divide the cells evenly. The length of the roller shaft is recommended to be smaller than and close to the side length of the battery sheet. The circumference of the drum is recommended to be larger than and close to the side length of the battery sheet. A plurality of electric heating ceramic rods are embedded in the drum, and the ceramic rods are evenly distributed along the circumference of the drum, and connected to the power supply through a slip ring.

Abstract

The invention discloses a rolling welding method for roller and achieves the effect of synchronously welding a plurality of linear welding materials. According to the scheme, a soldering bit adopts the roller; the roller is arranged at the front end of a soldering iron through a rotating shaft; the roller rolls the linear welding materials and a base plate and can implement rolling and welding at the same time; an electric heating device and a temperature sensor are arranged in the roller; a power line and a signal line are respectively communicated with each other through a sliding ring arranged on the rotating shaft; or a hot air gun and flame are used for heating the roller; the temperature sensor is arranged in the roller, so that the temperature of the roller can be controlled by controlling the power of the hot air gun or the degree of the flame.

Description

Technical field: [0001] The invention relates to a welding method, in particular to the welding of linear welding materials and flat substrates. Background technique: [0002] At present, common soldering iron tips are fixed, and the method of contact-type drag welding is used. For the junction strip of welding solar cells, it is difficult to control the temperature and strength, and the quality of welding cannot be guaranteed. Especially when a plurality of busbars need to be welded at the same time, it cannot be done. Invention content: [0003] The purpose of the present invention is to invent a welding method for simultaneous welding of multiple linear welding materials. [0004] The solution of the present invention is: the soldering iron head adopts a roller, and the roller is installed on the front end of the soldering iron through the rotating shaft, and the roller is rolled on the linear welding material and the substrate, and is welded while rolling; the axial l...
