Self tin adhesion welding head used for junction box bus bar welding machine

Abstract

The invention discloses a self tin adhesion welding head used for a junction box bus bar welding machine. A U shaped is formed as a whole, and a crack is formed in the middle; and the lower portion ofthe crack becomes wide gradually, and the bottom of the crack protrudes upwards to be in an arc shape. The bottom of the self tin adhesion welding head is horizontally provided with a groove; the side edge of the groove is provided with arch-shaped protrusions, so that cooperation with the groove is achieved, a soldering iron head in a soldering iron process is combined with the groove by us, that is, a tin adhesion block is arranged; the tin adhesion block is rectangular as a whole, and the side edge is provided with arch-shaped dents; the arch-shaped dents are matched with the arch-shaped protrusions; after the tin adhesion block and the self tin adhesion welding head are connected, the bottom of the tin adhesion block is higher than the bottom of the self tin adhesion welding head; andthe height difference meets the requirement of welding scar arrangement. The self tin adhesion welding head used for the junction box bus bar welding machine is ingenious in structural design and lowin improvement cost, the welding effect of the bus bar welding machine after being improved is greatly improved, and very good practicability is achieved.

Description

technical field [0001] The invention relates to the field of bus bar welding machines, in particular to a self-adhesive soldering joint for a junction box bus bar welding machine. Background technique [0002] The bus bar welding machine is usually a device for welding tin wire and circuit components together in the production process of photovoltaic products. According to the production requirements, the welding place should be a rectangular welding scar with a length of 5mm-20mm and a width of 2mm-6cm. The welding scar is smooth and smooth, and the product quality is good if the shape is regular, and it is best to weld it once. The welding head of the current bus bar welding machine is a rectangular metal. When welding, the tin wire is melted between the component and the welding head. Part of it is scattered, and the shape is difficult to be regular after repeated welding. The surface is not smooth and smooth. Multiple welding adjustments greatly affect the production eff...

[0002] The bus bar welding machine is usually a device for welding tin wire and circuit components together in the production process of photovoltaic products. According to the production requirements, the welding place should be a rectangular welding scar with a length of 5mm-20mm and a width of 2mm-6cm. The welding scar is smooth and smooth, and the product quality is good if the shape is regular, and it is best to weld it once. The welding head of the current bus bar welding machine is a rectangular metal. When welding, the tin wire is melted between the component and the welding head. Part of it is scattered, and the shape is difficult to be regular after multiple weldings. The surface is not smooth and smooth. Multiple welding adjustments greatly affect the production efficiency, and the quality of the produced products is not good.
