A kind of L-shaped upturned bus bar automatic preparation device and bus bar preparation method

Abstract

The invention discloses an L-shaped upwarping bus bar automatic preparation device and a preparation method of an L-shaped upwarping bus bar. An existing L-shaped upwarping bus bar preparation devicehas the problems that the automation degree is low, forming is not stable, or the bonding surface is prone to insufficient welding. The L-shaped upwarping bus bar automatic preparation device comprises a preparation rack, a material pulling mechanism, a material shifting mechanism, an L-shaped turnover upwarping mechanism and a feeding and straightening mechanism, wherein the feeding and straightening mechanism comprises a feeding roller, a feeding tensioning wheel, a bus bar straightening unit and a bus bar cutting-off unit, the material pulling mechanism comprises a material pulling guide rail, a bus bar track, a material pulling sliding block, a clamping assembly and a material pulling driving assembly, the L-shaped turnover upwarping mechanism comprises a bus bar upwarping pressure welding unit and two L-shaped turnover units, and the bus bar upwarping pressure welding unit comprises a fixing base, a first electrode block, a second electrode block and a single-side warping assembly. By means of the cooperative cooperation of all the mechanisms, full-automatic continuous production of the L-shaped upwarping bus bar can be realized.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to an automatic preparation device for an L-shaped upturned bus bar and a preparation method for the bus bar. Background technique [0002] During the production process of the entire solar photovoltaic module, multiple sets of battery strings need to be connected and welded together. In the bus welding process, it is necessary to use a bus bar that is L-shaped and has a right-angled side upturned; currently, there are different manufacturing devices for the L-shaped upturned bus bar. There are two welding strips that are welded into a right-angled shape by hand. , and then bent into an upturned shape; there are also straight strips that are bent into a right-angled shape, and then the bonding surfaces are welded together by means of an electric soldering iron. Although these methods can meet the final use requirements, they all have problems such as low degree of a...

AI Technical Summary

Problems solved by technology

Although these methods can meet the final use requirements, they all have the problems of low degree of automation, unstable molding, or easy welding of the bonding surface, and cannot reach the required tensile strength, etc.

None of the above are suitable for mass production applications in industrial automation
