Description
Technical field
The utility model relates to prewelding engineering device technique field more particularly to a kind of power battery tab prewelding devices.
Background technique
Lithium battery anode ear generally uses aluminium, and negative electrode lug generally uses copper to be all relatively suitble to welding procedure, and the two does afflux
Body is all the good conductivity because of the two, and quality is softer, less expensive.
206493026 U of patent CN, the patent provides a kind of pre- welders of automation tab, improve production efficiency,
It ensure that the welding quality of tab welding.But without the suitable prewelding position of offer, and do not consider when rolling over tab not
Good situation, resistance increases at tab welding, tab fracture, metal fillings is fallen that short circuit, broken tab insertion battery is caused to cause
Short circuit etc. seriously affects battery qualification rate, product quality, battery security.
203917501 U of patent No. CN, the utility model patent provide a kind of aluminum-shell battery pole ear bending device, improve
The effect difference problem of tab is rolled in cell production process.But it does not account in actual production, the scattered situation of tab
And the influence of pre- solder joint, prewelding position.
Utility model content
The purpose of this utility model is that solve the above-mentioned problems and provides a kind of power battery tab prewelding device.
The utility model achieves the above object through the following technical schemes:
The utility model includes battery battery core main body, copper polar ear, aluminium pole ears, folding tab mechanical arm, prewelding solder joint and fracture
One end of position, the battery battery core main body is provided with the copper polar ear, and aluminium pole ears are respectively set in the two sides of the copper polar ear
It is welded, forms the prewelding solder joint, the folding tab mechanical arm is set in the two sides of the prewelding solder joint, is located at the copper
The tab incident fracture position when middle and lower part of tab forms folding tab.
The utility model is preferred, and the battery battery core main body is carried out prewelding according to selected prewelding position when the welding
Welding, welding energy 300-3000J, negative pressure -40 arrives -100kpa dedusting when welding.
The utility model is preferred, the welding energy most preferably 800J, negative pressure most preferably -80kpa when the welding.
The utility model has the beneficial effects that:
The utility model provides a kind of power battery tab prewelding device, changes prewelding position, does not influence welding quality, weldering
Efficiency is connect, copper, aluminium pole ears crack conditions when folding tab is effectively solved, has pole to battery qualification rate, product quality, battery security
It is big to improve；The utility model has the advantages that structure is simple, performance is stable and service life is longer.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of power battery tab prewelding device described in the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1: the utility model include battery battery core main body 1, copper polar ear 2, aluminium pole ears 3, folding tab mechanical arm 4,
Prewelding solder joint 5 and fracture position 6, one end of battery battery core main body 1 are provided with copper polar ear 2, are respectively set in the two sides of copper polar ear 2
Aluminium pole ears 3 are welded, and prewelding solder joint 5 is formed, and in the two sides of prewelding solder joint 5 setting folding tab mechanical arm 4, are located at copper polar ear 2
Middle and lower part tab incident fracture position 6 when forming folding tab, by battery battery core main body 1 according to selected pre- welding position when welding
Set 6 carry out prewelding welding, welding energy 300-3000J, negative pressure -40 arrives -100kpa dedusting when welding.
Embodiment one:
The welding energy most preferably 800J, negative pressure most preferably -80kpa when the welding.
In conclusion the utility model provides a kind of power battery tab prewelding device, prewelding position is changed, does not influence to weld
Quality, welding efficiency are connect, copper, aluminium pole ears crack conditions when folding tab are effectively solved, to battery qualification rate, product quality, battery
Safety is greatly improved；The utility model has the advantages that structure is simple, performance is stable and service life is longer.
Those skilled in the art do not depart from the essence and spirit of the utility model, can realize this reality there are many deformation scheme
With novel, the above is only the preferred feasible embodiment of the utility model, not thereby limits to the power of the utility model
Sharp range, it is all with the variation of equivalent structure made by the utility model specification and accompanying drawing content, it is both contained in the utility model
Interest field within.
