Ultrasonic welding production test line for safety cover cap of power battery

Abstract

The invention relates to an ultrasonic welding production test line for a safety cover cap of a power battery. The ultrasonic welding production test line comprises a worktable, a feeding track, a welding station, a first transfer track, a leveling station, a second transfer track, an air tightness test station, a third transfer track, an internal resistance test station and a discharging track, wherein the feeding track, the welding station, the first transfer track, the leveling station, the second transfer track, the air tightness test station, the third transfer track, the internal resistance test station and the discharging track are arranged on the worktable in sequence; and one end of the feeding track is connected with a vibration plate or a discharged material from the former working procedure while the other end of the feeding track is corresponding to the welding station. The ultrasonic welding production test line is simple and compact in structure, capable of completing welding, leveling, air tightness testing and resistance testing of a cover cap top cover and an anti-explosion sheet in an integrated manner, high in automatic degree, and capable of effectively ensuring assembling quality and efficiency.

Description

Technical field [0001] The invention relates to a lithium battery automation equipment, in particular to a power battery safety cap ultrasonic welding production test line. Background technique [0002] Lithium-ion batteries are widely used in industrial production and daily life. As one of the important parts of lithium-ion batteries, the cap is composed of the top cover, orifice plate, explosion-proof disk and sealing ring; in the production of traditional lithium battery caps, the top cover needs to be The rupture disk is welded, and the existing manual operation is assembled and welded. The operation is cumbersome, time-consuming, laborious, low production efficiency, difficult to guarantee the quality, and affect the safety of the cap, and the deburring, air tightness test, and resistance test of the subsequent process must be separate The operation, the degree of automation is low, and the welding quality and efficiency cannot be effectively considered. Summary of the inve...

[0002] Lithium-ion batteries are widely used in industrial production and daily life. As one of the important components of lithium-ion batteries, the cap is composed of a top cover, an orifice plate, an explosion-proof disc and a sealing ring; in the production of traditional lithium battery caps, the top cover needs to be combined with The explosion-proof sheet is welded. The existing manual assembly and welding is cumbersome, time-consuming, labor-intensive, low in production efficiency, and difficult to guarantee quality, which affects the safety of the cap. In addition, the deburring, air-tightness test, and resistance test of the subsequent processes need to be performed separately. Operation, low degree of automation, can not effectively balance welding quality and efficiency
