Battery cover explosion-proof valve automatic welding equipment

Abstract

The invention discloses an automatic welding equipment for an explosion-proof valve of a battery cover plate, which comprises a circulating rotary conveying line and a battery cover plate feeding station, a laser coding station, a scanning code detection station, and an explosion-proof valve, which are sequentially arranged along the circulating and rotating conveying line. Material station, explosion-proof valve vibration correction station, explosion-proof valve flatness detection station, first NG unloading station, galvanometer spot welding station, galvanometer contour full welding station, welding inspection station, second NG unloading station Work station, finished product unloading station. The invention can realize the fully automatic welding production of the explosion-proof valve of the battery cover, meet the requirements of abundant station construction, the station setting is reasonable, the overall operation is smooth and efficient, and the welding quality of the explosion-proof valve is stable and reliable. The vibration correction of the explosion-proof valve is matched with the two-stage welding to ensure reliable and stable welding quality. It has the function of online laser coding, and is equipped with the design of sharing NG position for scanning code detection and flatness detection, which effectively avoids the welding scrap of recyclable products and improves the utilization rate of resources.

Description

technical field [0001] The invention relates to automatic welding equipment for explosion-proof valves of battery cover plates, and belongs to the technical field of automatic welding of explosion-proof valves. Background technique [0002] The power battery has a battery cover. The battery cover is also called a battery sealing plate. It is a thin-walled valve body and needs to be welded with an explosion-proof valve. When the internal pressure of the battery exceeds the specified value, the explosion-proof valve body will rupture to avoid battery bursting. Explosion-proof valves are generally welded by laser welding, which requires very high welding seams. [0003] The Chinese invention patent with the authorization announcement number CN107617820B discloses a power battery explosion-proof valve welding assembly and a welding method, which adopts the galvanometer welding assembly to realize the displacement on the gantry, so as to realize the position welding of the explos...
