Automatic laser welding machine for power battery cover plate and anti-explosion piece

Abstract

The invention discloses an automatic laser welding machine for a power battery cover plate and an anti-explosion piece. The automatic laser welding machine for the power battery cover plate and the anti-explosion piece comprises a cover plate storage disc conveying system, a cover plate moving system, a cover plate positioning system, an anti-explosion piece storage disc conveying system, an anti-explosion piece moving system, an anti-explosion piece vibrating regulating system, an XYZ-axial transmission system, a welding machine head and a laser welding system. A cover plate storage disc which holds the power battery cover plate can be conveyed to a working station of the cover plate moving system through the cover plate storage disc conveying system of the automatic laser welding machine, and then the power battery cover plate is moved to the cover plate positioning system through the cover plate moving system, and an anti-explosion piece storage disc which holds the anti-explosion piece can be conveyed to the working station of the anti-explosion piece moving system through the anti-explosion piece storage disc conveying system of the automatic laser welding machine, and then the anti-explosion piece is moved to the cover plate positioning system through the anti-explosion piece moving system, so that automatic conveying of the power battery cover plate and the anti-explosion piece is realized, the automation degree is high, the conveying efficiency is high and the speed is high; and the automatic laser welding machine for the power battery cover plate and the anti-explosion piece can realize secondary position regulation, and is high in welding precision and high in welding quality.

Description

technical field [0001] The invention relates to the technical field of power battery welding equipment, in particular to an automatic laser welding machine for a power battery cover plate and an explosion-proof sheet. Background technique [0002] In the power battery industry, in order to prevent explosion problems caused by high pressure inside the power battery, it is necessary to weld an explosion-proof sheet on the cover plate of the power battery. The function of the explosion-proof sheet is to prevent explosion when the internal pressure of the power battery is too high due to temperature rise or other factors. The tab will break to release the battery pressure and prevent the battery from exploding. [0003] At present, for the welding of precision workpieces such as power battery cover plates, laser welding machines are mainly used for welding. In the prior art, the laser welding machine for the power battery cover plate and the explosion-proof sheet includes a pow...

Problems solved by technology

[0004] However, in the prior art, the power battery cover transfer system only has the function of transferring the power battery cover with the explosion-proof disc to the welding area of ​​the laser welding system, but does not automatically transfer the power battery cover and the explosion-proof disc to the welding area of ​​the laser welding system. The function of being placed on the transmission system of the power battery cover plate causes the following problems in the existing laser welding machine for the power battery cover plate: First, the power battery cover plate and the explosion-proof sheet need to be placed manually, which is labor intensive. The efficiency of placement is very low; second, the accuracy of manual placement is low, which affects the quality of laser welding; third, there is no secondary position adjustment function for the power battery cover and explosion-proof sheet, and it is difficult to ensure welding accuracy
