Abstract
The utility model discloses a battery pack spot welding apparatus which overcomes shortcomings in a conventional technology, is convenient for production and operation, and improves production efficiency. A body of the battery pack spot welding apparatus is a rectangular solid with the height equal to the height of to-be-placed cells; sides of the rectangular solid are provided with U-shaped grooves for placing the cells; the bottom of each U-shaped groove is shaped as a circular arc and has the size corresponding to the size of the to-be-placed cells; the width of each U-shaped groove is equal to the diameter of the section of the cells; and end faces of the body are provided with nickel strap clamping grooves near bottoms of the U-shaped grooves. The battery pack spot welding apparatus has a simple structure, is convenient to operate and easy to manufacture, has low cost, and is capable of improving production efficiency effectively and reducing error rate.
Description
Technical field
The utility model relates to battery pack spot welding field, especially a kind of battery pack spot welding device.
Background technology
A large amount of resistance welders that use in the existing manufacturing enterprise are the equipment that nickel strap and battery are welded, extensive use in round battery combination production.Because battery pack needs several round electric cores to go here and there and connect, very inconvenient when producing, in the process of spot welding, cause the outlet of defective products easily.The deviation that has slightly that the nickel strap that is used for connecting is put just causes short circuit easily, has tangible short circuit hidden danger, and this just needs a kind of frock to guarantee the quality of welding, and eliminates safe hidden trouble, and enhances productivity simultaneously.
The utility model content
The technical problem that the utility model will solve provides and a kind ofly can overcome the deficiency that exists in the prior art, makes things convenient for production operation, the battery pack spot welding device of enhancing productivity.
For addressing the above problem; A kind of battery pack spot welding device of the utility model; It is characterized in that: the body of said battery pack spot welding device be a height with the cuboid that equates of the electric core height that will put; This cuboid side offers the U type groove of placing electric core, and the bottom of said U type groove is a circular arc and corresponding with the electric core size of being placed, and the width of U type groove equates with electric core diameter of section; Body end face near the bottom of U type groove is provided with the nickel strap draw-in groove.
Electric core is placed in the U type groove of putting electric core; Then nickel strap is put in the nickel strap draw-in groove; The height of battery pack spot welding device is consistent with the height of electric core, put nickel strap like this after, nickel strap just can be attached to the two poles of the earth of electric core fully; Thereby improved the accuracy of nickel strap location, in welding, also located very easily.The battery pack spot welding device of the utility model structure, simple in structure, handled easily, and make easily, with low cost, can effectively enhance productivity, reduce fault rate.
