Abstract
The utility model discloses a battery tab welding positioning die which comprises a base, a pressing fit strip, an aluminum-nickel positioning plate and a pressing strip limiting sliding block. The base is provided with an aluminum-nickel positioning plate clamping groove, a magnet is inlaid in the concave area in the base to be used for attracting the pressing fit strip, pressing strip limiting sliding blocks are installed on the two sides of the aluminum-nickel positioning plate and used for adjusting the position of the pressing fit strip according to products of different specifications, and positioning grooves are also formed in the aluminum-nickel positioning plate for limiting the positions of an aluminum battery tab and a nickel sheet. According to the battery tab welding positioning die, the aluminum-nickel limiting plate detachable structure is adopted, and rapid replacement is achieved according to battery tabs of different specifications; During battery tab welding, one set of aluminum sheets and nickel sheets are placed on the limiting plate at first, the positioning grooves in the limiting plate are utilized for arrangement and alignment, the products can be orderly and standard during welding, and the percent of pass and production efficiency are improved.
Description
Technical field
The utility model relates to the lug production technical field that polymer Li-ion battery is used, and at the composing pattern of aluminium flake one end of lug welding nickel sheet, belongs to energy-storage battery technical field specifically.
Background technology
Lug, that polymer Li-ion battery is (hereinafter to be referred as lithium battery, be widely used in the numerous areas such as mobile phone, flashlight, electronic toy, the electrodynamic automobile of lithium) a kind of raw material of product, be the element of the welded cruciformity of lug special glue and sheet metal (being generally aluminium flake, nickel sheet etc.) heat seal, its function is: the one, and the sheet metal by lug extracts both positive and negative polarity for discharging and recharging from battery core; The 2nd, by the special glue of lug and the heat seal of aluminum plastic film (shell of lithium battery), seal, can say the door of lug system lithium cell.
The raw material of lug are divided into three kinds: the positive electrode of battery, and---conventionally using aluminium (Al), negative material---uses nickel (Ni) and lug special glue conventionally, and two lug special glue are clipped in the middle sheet metal and heat seal is welded as a whole is lug product.
Aluminium pole ears will be transferred nickel sheet conventionally so that scolding tin, yet, in the process of lug switching nickel sheet, how to allow superimposed consistent, the uniform thorny problem that becomes in part of aluminium flake and nickel sheet.Conventionally adopt in the market double faced adhesive tape by hand aluminium pole ears to be pasted to the rear switching of a version nickel sheet, its drawback is: 1, production efficiency is lower, and spillage of material is high; 2, only have use window type metal derby pressing mold by aluminium flake and the pressing of nickel sheet so that laser weld, but pressing mold is easily distortion under laser long term, the uniformity inconvenience of pressing tight ness rating is controlled, directly cause welding inhomogeneous, unitary mould volume is large and heavy simultaneously, and common woman worker operates inconvenience.
Utility model content
The utility model, in order to address the above problem, has designed a kind of jig of lug switching nickel sheet, and its object is: the uniformity and the reliability that improve lug aluminium flake and the welding of nickel sheet.
The utility model technical solution:
A kind of tab welding jig, comprise base, pressing bar, aluminium nickel location version and press strip position limiting slide block, it is characterized in that: on base, offer aluminium nickel location version screens groove, magnetite is inlayed in order to adsorb pressing bar by base concave district, version both sides, aluminium nickel location are provided with press strip position limiting slide block in order to adjust pressing bar position according to products of different specifications, in the version of aluminium nickel location, are also provided with detent to limit the position of aluminium pole ears and nickel sheet.
Described detent has 18～22.
In the middle of described press strip position limiting slide block, be provided with long kidney-shaped hole, be fixed by screws on base.
Described base is concave structure, and negative area is provided with magnetite, and described pressing bar is steel bar or iron bar.
The beneficial effects of the utility model:
The utility model is simple in structure, easy for operation, adopt aluminium nickel limit plate demountable structure, can be according to the lug quick-replaceable of different size, this mould is first placed on one group of aluminium flake and nickel sheet on limit plate when tab welding operation, utilize the detent on it to arrange, align, when welding, can make the neat standard of product, improve qualification rate and production efficiency.
Accompanying drawing explanation
Fig. 1: the utility model result schematic diagram.
Wherein: base 1, pressing bar 2, aluminium nickel location version 3 and press strip position limiting slide block 4.
The specific embodiment
Below in conjunction with accompanying drawing, illustrate the utility model.
As shown in Figure 1, a kind of tab welding jig, mainly by base 1, pressing bar 2, aluminium nickel location version 3 and press strip position limiting slide block 4 form, on base 1, offer aluminium nickel location version screens groove, magnetite is inlayed in order to adsorb pressing bar 2 by base concave district, version 3 both sides, aluminium nickel location are provided with press strip position limiting slide block 4 in order to adjust pressing bar position according to products of different specifications, in the version of aluminium nickel location, be also provided with detent to limit the position of aluminium pole ears and nickel sheet, described detent has 18～22, in the middle of press strip position limiting slide block, be provided with long kidney-shaped hole, be fixed by screws on base, base is concave structure, negative area is provided with magnetite, described fixedly press strip is steel bar or iron bar.
Embodiment: selected a kind of product specification, install the aluminium nickel location version of this specification, and according to the position of this specification adjustment pressing bar position limiting slide block, enter aluminium-to-nickel operation procedure---the first step: aluminium pole ears group fitly put aluminium nickel relative to nickel sheet group is located in version; Second step: the lower limb that pressing bar is withstood to position limiting slide block puts down, magnetite adsorbs pressing bar, and pressing bar is about to aluminium flake and the even pressing of nickel sheet; The 3rd step: suitably arrange the closed state of aluminium flake and nickel sheet after pressing, can deliver to laser and turn under nickel machine and weld, so far aluminum ear nickel-converting operation completes.
To sum up, the utility model accomplishes the end in view.
