Danger, and battery welding position during high-multiplying power discharge is easily influenced battery safety in utilization by high temperature melt.In addition scolding tin
Position internal resistance is larger, influences cell discharge efficiency.
Therefore, it is necessary to which providing a kind of new equipment comes anchor leg and cell polar ear, contacted with reducing lead with lug
Position internal resistance, improve battery safety, increase battery discharge multiplying power.
Utility model content
Lead can be reduced the purpose of this utility model is to provide one kind, and position internal resistance, raising cell safety are contacted with lug
Performance, the equipment for increasing battery discharge multiplying power.
To achieve these goals, the utility model provides a kind of lug and surpasses welding machine, including body, soldering tip and bed die,
Supersonic generator, transducer and ultrasonic transformer are equipped with the body, a bottom plate, the bottom plate are extended in the side of the body
On be fixed with mounting base, the bed die is arranged in the mounting base and with lower welding surface upward, the soldering tip and the change
Width bar is connected and stretched out by the side of the body, and the soldering tip has the upper welding surface opposite with the lower welding surface.
Compared with prior art, this lug is surpassed welding machine and is consolidated lead and cell polar ear using the technology of ultrasonic bonding
It is fixed, have the advantages that welding efficiency is high, welding effect is good, security performance is high during high-multiplying power discharge, and contact an internal resistance
It is small, be conducive to improve the discharging efficiency of lithium ion battery.
It is preferred that the upper welding surface on lower welding surface with being equipped with multiple bulge-structures.Bulge-structure is set to make two
Rough structure is presented in welding surface, is conducive to the bond strength of reinforced leads and lug.
It is preferred that the mounting base includes two clamping parts, the bed die, which is clamped, to be positioned between two clamping parts.Peace
Dress seat is fixed by two clamping parts, can easily carry out dismounting and change.
Specifically, the mounting base further includes main body, and two clamping parts are fixed on the both ends in the main body, the master

Brief description of the drawings
Fig. 1 is the stereogram that the utility model lug surpasses welding machine.
Fig. 2 is that lug surpasses the schematic diagram of mounting base and bed die in welding machine.
Embodiment
Description is made with reference to preferred embodiment of the Figure of description provided to the utility model.
As shown in Figure 1 and Figure 2, the utility model provides a kind of lug and surpasses welding machine, including body 1, soldering tip 2 and bed die 3.
This lug surpasses welding machine and is used to cell polar ear and lead are carried out hot melt fixation by way of ultrasonic bonding, therefore lug surpasses weldering
The necessary devices that supersonic generator, transducer and ultrasonic transformer etc. realize ultrasonic bonding are provided with the body 1 of machine.
A bottom plate 11 is extended in the side of body 1, and mounting base 4 is fixed with bottom plate 11, and bed die 3 is arranged in mounting base 4 simultaneously
With lower welding surface 31 upward, soldering tip 2 is connected with ultrasonic transformer and is stretched out by the side of body 1, and soldering tip 2 has and lower welding surface
31 opposite upper welding surfaces 21.It is put in after being stacked cell polar ear and lead when being welded on bed die 3, is then turned on machine,
Soldering tip 2, which can move down, is pressed onto lug with lead, both are welded together.
Mounting base 4 includes main body 41 and clamping part 42 in the present embodiment, and two clamping parts 42 are fixed on the two of 41 upper end of main body
Side, clamping part 42 and main body 41 are integrated formed structures, and the centre position of main body 41 offers a gap 411.Bed die 3 is clamped
It is fixed between two clamping parts 42 and is carried in main body 41.Two clamping parts 42 can outwards somewhat deformation and make distance between the two
Become larger, therefore the replacement bed die 3 in mounting base 4 can be facilitated.Due to the setting in gap 411 in main body 41, two clampings are improved
The deformation nature in portion 42, is more advantageous to the demolition, installation of bed die 3.
It is preferred that upper welding surface 21, with being equipped with multiple bulge-structures on lower welding surface 31, the setting of bulge-structure causes
Upper welding surface 21 shows rough shape with lower welding surface 31, strong due to improving the combination between lead and cell polar ear
Degree.
Compared with prior art, this lug is surpassed welding machine and is consolidated lead and cell polar ear using the technology of ultrasonic bonding
It is fixed, have the advantages that welding efficiency is high, welding effect is good, security performance is high during high-multiplying power discharge, and contact an internal resistance
It is small, be conducive to improve the discharging efficiency of lithium ion battery.
Above disclosed is only the preferred embodiments of the utility model, its effect is to facilitate those skilled in the art
Understand and implement according to this, the interest field of the utility model cannot be limited with this certainly, thus it is special according to the present utility model application
The equivalent variations that sharp scope is made, still fall within the scope that the utility model is covered.
