Abstract

The utility model discloses a welding spot positioning device for spot welding of a lithium-ion battery, comprising a spot welding base, linear guide tracks which are connected with positioning pins thereon and connected on the spot welding base and a positioning base which is connected on the linear guide tracks and matched therewith in a sliding manner, a spot welding clamp is connected on the positioning base, and positioning blocks which are matched with the positioning base by the transverse movement via connecting structures are respectively connected on the positioning base which are positioned at the both sides of the spot welding clamp. The welding spot positioning device has the advantages that the structure is simple, the usage is convenient, and the welding spot positioning device can be used in the production and manufacturing process of various liquid square lithium-ion batteries and polymer batteries, thus effectively ensuring the product quality and improving the productivity.

Description

Lithium ion battery weld nugget positioner
Technical field
The utility model relates to the weld nugget positioner, particularly lithium ion battery weld nugget positioner.
Background technology
At present; under normal conditions, the security in order to ensure lithium ion battery uses must be assembled together lithium-ion electric core and protection circuit plate; guarantee the security that the finished product battery uses by the protection circuit plate, but the connected mode between them is finished by the technology of spot welding generally.Manual positioning action is generally adopted between the two welding in actual production process, manual operations can owing to can't guarantee between the two the depth of parallelism and the position of two solder joints cause the bad of weld strength.The meeting that has causes the damage of cell polar ear and protection circuit plate nickel sheet, and has to scrap; The meeting that has influences the service life of product, causes user's complaint; Serious meeting influences security of products.
Summary of the invention
The purpose of this utility model is to overcome the prior art weak point, and a kind of simple in structure, easy to use, lithium ion battery weld nugget positioner accurately and reliably is provided.
The technical scheme that the utility model adopted is for achieving the above object:
Lithium ion battery weld nugget positioner, it comprises the spot welding base, be connected the line slideway, the positioning seat that are connected with alignment pin on the described spot welding base its is connected on the described line slideway and is slidingly fitted with it, on described positioning seat, be connected with spot welding fixture (SWFX), on the positioning seat that is positioned at described spot welding fixture (SWFX) both sides, be connected with respectively by syndeton and laterally move the locating piece that cooperates with it mutually.
The beneficial effects of the utility model are:
1, simple to operate, the efficient height.Before starting working; as long as after allowing the technician adjust this device by master body; operator welds as long as simply battery and protection circuit plate are put into spot welding fixture (SWFX); removed the difference of different personnel's gimmicks from; the risk that unsettled misgivings of bond pad locations and welding quality can't effectively guarantee; thereby more accurate, the believable product that produces.
2, range of application is very extensive, various squares, and polymer, liquid battery all can be suitable for.
3, cost is low, changes convenient and swift.Adopt this device, efficient height, with low cost.
In a word, the utility model is simple in structure, easy to use, can be used for the manufacturing process of various liquid square lithium ion batteries and polymer battery, effectively guarantees product quality and enhances productivity.
Description of drawings
Fig. 1 is a lithium ion battery weld nugget positioner front view of the present utility model;
Fig. 2 is the vertical view of device shown in Figure 1;
Fig. 3 is the spot welding fixture (SWFX) view of device shown in Figure 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done to describe in detail.
Lithium ion battery weld nugget positioner as shown in drawings, it comprises spot welding base 2, be connected the line slideway 4, the positioning seat 3 that are connected with alignment pin 5 on the described spot welding base 2 its is connected on the described line slideway 4 and is slidingly fitted with it, on described positioning seat 3, be connected with spot welding fixture (SWFX) 8, on the positioning seat that is positioned at described spot welding fixture (SWFX) both sides, be connected with respectively by syndeton and laterally move the locating piece 1 that cooperates with it mutually.Described syndeton comprises out the U-shaped groove on locating piece, is provided with bolt and is connected with described positioning seat in described groove.
Lithium ion battery weld nugget positioner is characterized in that passing through X; Y; the Position Control of Z direction can be so that two nickel contact bond pad locations of battery plus-negative plate ear and protection circuit plate B+, B-be effectively guaranteed; because the mobility on the Y direction; by the adjustment of alignment pin on the spot welding base, solder joint and back solder joint and the optimum distance between them before can controlling.
Concrete using method:
1) the spot welding base at first is fixed on the work top of mash welder, and fastening good with screw;
2) electric core 7 and protection circuit plate 6 are put into spot welding fixture (SWFX), place on request;
3) this moment spot welding fixture (SWFX) is put into positioning seat again, the Y direction of solder joint is adjusted to the position that needs by the alignment pin of spot welding base; The position that needs adjusted to the directions X of solder joint by locating piece by positioning seat; The upper/lower electrode of adjustment mash welder and cell polar ear and protection circuit plate contact are to the position that needs.
4) positioning seat is promoted forward, can carry out the welding of first solder joint during to extreme position; Promote then backward, can carry out the welding of second solder joint during to extreme position.
5) the follow-up work spot welding fixture (SWFX) that only needs to be placed with electric core and protection circuit plate is put into and is repeated 4 in the positioning seat) action get final product.
Above-mentioned with reference to embodiment to the detailed description that this lithium ion battery weld nugget positioner carries out, be illustrative rather than determinate, therefore, should belong within the protection domain of the present utility model in the variation and the modification that do not break away under the utility model general plotting.
