Abstract

The utility model relates to an ultrasonic welding device for welding lithium battery tabs and cap components, which comprises an ultrasonic welding machine and a positioning mould, wherein the positioning mould is arranged under the welding head of the ultrasonic welding machine and a positioning groove is arranged in the positioning mould. The utility model is characterized in that a convex table is arranged at the bottom of the positioning groove. The utility model solves the technical problem that the cap components and battery tabs are bended when welded by ultrasonic welding devices.

Description

Be used to weld the ultrasonic brazing unit of lithium ion cell polar ear and cap assemblies
Technical field
The utility model relates to the lithium ion battery production equipment, is specifically related to weld the ultrasonic brazing unit of lithium ion cell polar ear and cap assemblies.
Background technology
Rectangular lithium ion battery comprises cylindrical shell, be contained in electrode assemblie and the electrolyte in the cylindrical shell and be used for the cap assemblies of sealed cylinder; Wherein electrode assemblie is to apply the positive and negative plate coiling that predetermined active material forms to form by barrier film, on metallic matrix, and is respectively equipped with anode ear, the negative electrode lug that is used to draw electric current on the positive plate, negative plate; Anode ear and negative electrode lug are electrically connected with cap assemblies and cylindrical shell respectively.The welding of anode ear and cap assemblies is welded with ultrasonic welding machine; Existing welding procedure is as follows: earlier cap assemblies is positioned in the weld mold of ultrasonic welding machine, the soldering tip of ultrasonic welding machine is welded as a whole cap assemblies and anode ear then.Since cover plate all round have a residual burr of machining, the punching press meeting of soldering tip makes cap assemblies flexural deformation during welding, cause cap assemblies and cylindrical shell not to coincide, so that battery can not welded seal.
The utility model content
The purpose of this utility model is the technical problem that solution ultrasonic welding machine welding cap assemblies and lug cause the cap assemblies bending, and a kind of ultrasonic brazing unit that is used to weld cap assemblies and lug is provided.
The technical solution of the utility model: the ultrasonic brazing unit that is used to weld lithium ion cell polar ear and cap assemblies, comprise ultrasonic welding machine, jig, jig is arranged on the below of ultrasonic welding machine soldering tip, jig is provided with detent, it is characterized in that, also be provided with boss on the bottom surface of described detent.
Further, described boss width is less than the detent width.
Further, described boss height is less than the detent degree of depth.
The utility model is provided with boss by the bottom surface at the jig detent on the basis of original welder, solved the cap assemblies problem on deformation that welding causes.
Description of drawings
Fig. 1 is the ultrasonic brazing unit stereogram that is used to weld lithium ion cell polar ear and cap assemblies,
Fig. 2 is 2 times of enlarged drawings of the A-A cutaway view of Fig. 1,
Fig. 3 is the schematic diagram that welder welds this assembly, lug.
The specific embodiment
As shown in Figure 1 and Figure 2, be used to weld the ultrasonic brazing unit of lithium ion cell polar ear and cap assemblies, comprise ultrasonic welding machine 1 and jig 3, jig 3 is arranged on the below of ultrasonic welding machine 1 soldering tip 2, wherein jig 3 is provided with detent 4, detent 4 bottom surfaces are provided with boss 5, these boss 5 width are less than detent 4 width, boss 5 height are less than detent 4 degree of depth, after cap assemblies was positioned detent 4, burr that the processing on the cap assemblies is residual or corner were housed inside the both sides of boss 5.
With reference to Fig. 3, detent on the jig 3 is with cap assemblies 7 location, because detent 7 is supported by boss 5, therefore, cap assemblies 7 can not supported by the burr on it, when soldering tip 2 is descending when exerting pressure cap assemblies 7 with lug 8 welding, soldering tip 2 can be with cap assemblies 7 compressive strains, and welding effect is good.

Claims (3)
