Abstract

The utility model discloses a lithium ion battery cap and positive tab ultrasonic welding device which comprises an ultrasonic generator, a pneumatic portion, a transducer, a welding head and a welding base. The welding head corresponds to the welding base, and a pressure welding block is arranged in the head of the welding head and is in a shape of a cuboid. The welding base is mainly formed by a base body. The upper end of the base body is cylindrical, an annular groove is formed in the upper top end of the cylinder, and a pit is formed in the middle of the annular groove of the cylindrical welding base. The lithium ion battery cap and positive tab ultrasonic welding device has the advantage that ultrasonic wave is adopted for conducting welding, welding is fast, device investment is reduced, and production cost is effectively reduced. The pressure welding block is in contact with a welding piece, welding surface effect is uniform, welding spot contact area is large, welding is firm, and product quality is effectively guaranteed.

Description

Lithium ion battery cover and anode ear ultrasonic brazing unit
Technical field
The utility model relates to the technical field of welder, more particularly relates to the technical field of welder for lithium ion battery.
Background technology
Lithium ion battery is mainly by shell, block, anodal and negative pole forms, positive pole welds together by anode ear and block, negative pole welds together by negative electrode lug and outer casing bottom, block enclosing cover is put the opening part at shell, block with a kind of welding manner of anode ear is at present: adopt laser to weld, not only solder joint contact area is little for it, easily produce rosin joint phenomenon, cause internal resistance unstable, thereby greatly affected the quality stability of product, and welding efficiency is low, produce 20,000 batteries daily and carry out weld job with regard to 3 laser welders of needs, investment of production equipment is larger, also increased direct labor's input simultaneously, improved production cost, another kind of welding manner is: adopt ultrasonic wave to weld, existing ultrasonic welding machine mainly includes supersonic generator, pneumatic part, transducer, plumb joint and welding base, supersonic generator is mainly the power utilization electronic circuit of power frequency 50HZ to be changed into the high pressure electric wave of high frequency, the high pressure electric wave that transducer just produces supersonic generator converts high-frequency mechanical vibration to, and act on weldment by corresponding plumb joint and welding base, pneumatic part Main Function is in process, to complete pressurization, pressurize equal pressure requirements of one's work, the weak point that existing ultrasonic welding machine exists is: the pressure welding position of plumb joint head can not adapt to the needs that weld battery pole ear, exist pressure welding point area little, equally also can cause solder joint contact area little, easily produce the phenomenon of rosin joint, the welding base corresponding with plumb joint can not adapt to the needs of locating battery cap in addition, cause face of weld effect inconsistent, welding quality is unstable.
Utility model content
The purpose of this utility model provides a kind of speed of welding fast in order to solve above-mentioned deficiency exactly, equipment investment is little, can effectively reduce production costs, face of weld effect is consistent, solder joint contact area is large, firm welding, lithium ion battery cover and anode ear ultrasonic brazing unit that can effective guarantee product quality.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
Lithium ion battery cover and anode ear ultrasonic brazing unit, include supersonic generator, pneumatic part, transducer, plumb joint and welding base, plumb joint is corresponding with welding base, the head of described plumb joint is provided with press welding block, this press welding block is rectangular stereo structure, and described welding base mainly consists of pedestal, and this pedestal upper end is cylindric, on this is columned, top offers annular groove, is positioned at the middle pit that also offers of annular groove of cylindric welding base.
The annular groove degree of depth of described cylindric welding base is 1.5-2 millimeters.
The press welding block of described plumb joint head is corresponding with the pit in the middle of welding base.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: adopt ultrasonic wave to weld, speed of welding is fast, reduced the input of equipment, thereby effectively reduce production cost, adopt press welding block to contact with weldment, not only face of weld effect is consistent, and solder joint contact area is large, weld more firm, thereby effective guarantee the quality of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure for amplifying schematic diagram of welding base in Fig. 1;
Fig. 3 is the local structure for amplifying schematic diagram in A place in Fig. 1.
The specific embodiment
By Fig. 1, shown in Fig. 2 and Fig. 3, lithium ion battery cover and anode ear ultrasonic brazing unit, include supersonic generator 1, pneumatic part 2, transducer 3, plumb joint 4 and welding base 5, supersonic generator 1 is mainly the power utilization electronic circuit of power frequency 50HZ to be changed into the high pressure electric wave of high frequency, the high pressure electric wave that transducer 3 just produces supersonic generator 1 converts high-frequency mechanical vibration to, and act on weldment by corresponding plumb joint 4 and welding base 5, pneumatic part 2 Main Functions are in process, to complete pressurization, pressurize equal pressure requirements of one's work, the self structure of above-mentioned parts and interconnected relationship are prior art, at this without repeating.This creation point be described plumb joint 4 and welding base 5 corresponding, head at plumb joint 4 is provided with press welding block 6, this press welding block 6 is rectangular stereo structure, described welding base 5 mainly consists of pedestal, this pedestal upper end is cylindric 7, mainly for handled easily, on this upper top of cylindric 7, offer annular groove 8, be positioned at the middle pit 9 that also offers of annular groove 8 of cylindric welding base 5, the press welding block 6 of plumb joint 4 heads is corresponding with the pit 9 in the middle of welding base 5, annular groove 8 degree of depth of described cylindric welding base 5 are 1.5-2 millimeters and are advisable, be convenient to like this effective location of battery cap.
