Abstract
The utility model provides a circular lithium ion battery cover welding frock, which comprises a frock main body, an orifice plate, a strong magnet and a pressing plate. The appearance dimension of the frock main body is the same with that of the battery cover. The orifice plate is embedded into the groove of the frock main body and the strong magnet is embedded inside the frock main body. The pressing plate is arranged on the upper surface of the frock main body and the orifice plate is fixed by the mutual attraction of the pressing plate and the strong magnet. The circular lithium ion battery cover welding frock can meet the requirements of equipment debugging and production process inspection without affecting the welding quality and wasting the battery cover. The welding frock is convenient in operation, which can be used repeatedly. Therefore, the production cost is greatly reduced. The circular lithium ion battery cover welding frock is suitable for large-scale industrial production.
Description
Technical field
The utility model relates to a kind of frock, especially a kind of round lithium-ion battery welding tooling.
Background technology
In round lithium ion battery production process, it is that positive pole and battery cover with battery utmost point group welds together that one procedure is arranged, because the material of the orifice plate on anode ear and the battery cover all is an aluminium, and aluminium is more hard-to-weld material, so use laser to weld, but the control of the energy of laser beam is very difficult, so equipment will often be debugged in producing, also to strengthen the frequency of weld strength between check anode ear and the orifice plate in the production process, these all need to consume a large amount of battery covers, thereby have caused great waste.Therefore, design the frock of a kind of round lithium ion cell positive ear and battery cover orifice plate welding, can guarantee the outward appearance and the welding quality of welding, consuming cells lid not again, thus reach the purpose of the loss that reduces cost, have very important production practices meaning.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of round lithium-ion battery welding tooling.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of round lithium-ion battery welding tooling, form by frock main body, orifice plate, strong magnets and pressing plate, the appearance and size of described frock main body is identical with battery cover, orifice plate embeds in the groove of frock main body, strong magnets embeds the frock body interior, pressing plate places frock main body upper surface, by attracting each other with strong magnets orifice plate is fixed.
Preferably, above-mentioned round lithium-ion battery welding tooling, described orifice plate is a field-replaceable unit.
Preferably, above-mentioned round lithium-ion battery welding tooling, the material of described frock main body is a metal material.
Preferably, above-mentioned round lithium-ion battery welding tooling, the material of described frock main body is stainless steel or copper.
The utility model structure has following beneficial effect:
Above-mentioned round lithium-ion battery welding tooling has reached equipment debugging, production process test requirements, does not influence welding quality; simultaneously do not waste battery cover again, easy to operate, can use repeatedly; greatly reduce production cost, be fit to requirements of large-scale industrial production.
Description of drawings
Fig. 1 is the structural representation of round lithium-ion battery welding tooling described in the utility model.
Among the figure: 1-frock main body 2-orifice plate 3-strong magnets 4-pressing plate
The specific embodiment
For further specifying the utility model, existing conjunction with figs. is described in detail:
As shown in Figure 1, described round lithium-ion battery welding tooling, be made up of frock main body 1, orifice plate 2, strong magnets 3 and pressing plate 4, the appearance and size of described frock main body 1 is identical with battery cover, adopts copper material to be prepared from, can use repeatedly, orifice plate 2 is a field-replaceable unit, and orifice plate 2 embeds in the groove of frock main body 1, and strong magnets 3 embeds frock main body 1 inside, pressing plate 4 places frock main body 1 upper surface, by attracting each other with strong magnets 3 orifice plate 2 is fixed.
On the specific implementation, only need the cheap battery cover orifice plate 2 of replacement cost during use, earlier pressing plate 4 is taken off, orifice plate 2 is put into the groove of frock main body 1, again pressing plate 4 is pressed in frock main body 1 and upper surfaces strong magnets 3 opposite positions, owing in the frock main body 1 strong magnets 3 is installed, reaches the fixedly effect of orifice plate 2 thereby can hold pressing plate 4; The laser beam that laser equipment sends with 2 welding of anode ear and orifice plate after, just can open pressing plate 4, from the groove of frock main body 1, take out orifice plate 2, tested the weld strength of anode ear and orifice plate 2; Continue to put into new orifice plate 2 and just can carry out the welding of next group, saved the higher battery cover of cost.
As seen, the result of use of described round lithium-ion battery welding tooling is equal to battery cover, can use repeatedly, and is easy to operate; Orifice plate 2 costs that consume are very low, saved the higher battery cover of great amount of cost.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
