Abstract
The utility model discloses an assist compaction device for lithium ion battery laser welding, which has the advantages of high efficiency and convenience in operation and can be used for guaranteeing the welding quality. The assist compaction device comprises a base, a clamp which is arranged on the base and used for fixing a battery and a cylinder vertically fixed on the base, wherein the cylinder is connected with a press claw connecting rod and can be used for driving the compaction claw connecting rod to move up and down; and a compaction claw is arranged at the front end of the compaction claw connecting rod and positioned above the clamp. According to the assist compaction device for lithium ion battery laser welding, an electrode tab and a nickel slice are compacted by adopting a pneumatic compaction mode so as to achieve the purpose that compaction force is kept consistent before welding; and pressure intensity can be regulated as required so as to regulate the compaction force to the battery tab and the nickel slice.
Description
Technical field
The utility model relates to a kind of lithium ion battery production process equipment, especially a kind of lithium ion battery laser weld auxiliary clamping device.
Background technology
In the lithium ion polymer battery industry, need require utilizing Laser Welding equipment to carry out laser weld after lug and the overlapping covering of nickel sheet according to project organization in the battery production process.In the process of welding, need battery pole ear and the overlapping covering back contraposition of nickel sheet be compressed,, guarantee welding quality during Laser Welding to guarantee that battery pole ear closely contacts with the nickel sheet through servicing unit.This operation all is by the completion of common welding auxiliary clamping device through manually compressing usually; And, cause lug different with the exposure level of nickel sheet because in the process that manually compresses, the dynamics that each operative employee uses is different; That have even can not well contact; Gapped, cause rosin joint during laser weld, weld failure welding phenomenon appearance such as quick-fried, influence product quality.
The utility model content
It is high, easy to operate that the technical problem that the utility model will solve provides a kind of efficient, and can guarantee the lithium ion battery laser weld auxiliary clamping device of welding quality.
For addressing the above problem, a kind of lithium ion battery laser weld auxiliary clamping device of the utility model comprises base and is arranged on the anchor clamps that are used for fixing battery on the base, also comprises the cylinder that vertically is fixed on the base; Cylinder is connected with the paw connecting rod and can drives the paw connecting rod and moves up and down, and paw is arranged at the leading section of paw connecting rod and is positioned at the top of anchor clamps.
Said cylinder is connected with the paw connecting rod through gangbar; This gangbar lower end links to each other with cylinder, and the through hole on the paw connecting rod is passed in the upper end, and the part that said gangbar is positioned at paw connecting rod top is with stage clip; The stage clip lower end withstands on the paw connecting rod, and the upper end withstands on the stage clip block at gangbar top.
Adopt the lithium ion battery laser weld auxiliary clamping device of the utility model structure; Mode through pneumatic clamping compresses lug and nickel sheet; Thereby realize that the thrust before the welding is consistent, can regulate the realization of air pressure intensity compresses strength to battery pole ear and nickel sheet adjusting as required.In operating aspect, the employee only needs to be placed on battery in the anchor clamps, starts cylinder, and paw just can compress lug and nickel sheet, and then startup laser welding apparatus switch has just been accomplished laser weld.This utility model can be accomplished compressing of lug and nickel sheet preferably, and the auxiliary laser weld of accomplishing has characteristics such as efficient height, easy to operate, range of application.
