Abstract
The utility model provides welding tool equipment of a full-automatic resistance welding machine for circular lithium ion batteries. The welding tool equipment is formed by fixing an upper die and a lower die through locking handles, wherein position limiting grooves of which the thicknesses are equal to or slightly smaller than the thicknesses of nickel straps to be welded are formed on the inner sides of the upper die and the lower die; and the bottom surfaces of the position limiting grooves are in the shapes corresponding to the nickel straps to be welded. The welding tool equipment of the full-automatic resistance welding machine for the circular lithium ion batteries has the advantages that the positions of the nickel straps and battery cores are effectively fixed and then the nickel straps can be accurately welded with the battery cores by adopting the full-automatic resistance welding machine, so that manual shaking phenomena is avoided from happening in the welding process, the nickel straps and the battery cores are positioned accurately, and the phenomena of lack of weld, welding explosion, and the like are prevented from occurring; meanwhile, the production efficiency is greatly improved, the rejection rate of battery core combinations is reduced, and the production cost is saved; and besides, the welding tool equipment has an attractive appearance and high consistency and satisfies the requirements of large-scale industrial production.
Description
Technical field
The utility model relates to battery and makes field, the full-automatic resistance welding machine of especially a kind of round lithium ion battery welding tooling.
Background technology
At present, round lithium-ion electric core compound mode basically all is to adopt resistance welder that nickel strap is welded.There is difficulty owing to connect the locate mode of nickel strap and round lithium-ion electric core group; Make round lithium-ion electric core adopt situation that full-automatic resistance welding machine realizes that battery is connected with nickel strap seldom; Especially the situation of electric tool and battery of electric bicycle employing full-automatic welding machine all is the location of adopting artificial hand push battery pack to realize nickel strap and battery pack still less.Often have Lou weldering in this case, weld undesirable element generations such as quick-fried, can not fundamentally guarantee the quality of battery pack.
The utility model content
The utility model technical problem to be solved is to provide the full-automatic resistance welding machine of a kind of round lithium ion battery welding tooling.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
The full-automatic resistance welding machine of a kind of round lithium ion battery welding tooling; Fixedly form through lock handle by upper die and lower die; It is identical or slightly be shallower than the stopper slot of nickel strap thickness to be welded that the inboard of said upper die and lower die is provided with thickness, and the stopper slot bottom surface has and nickel strap corresponding shape to be welded.
Preferably, the full-automatic resistance welding machine of above-mentioned round lithium ion battery welding tooling, said lock handle is fixed on a side of counterdie, and patrix is provided with and is used for being fixedly coupled the position with lock handle.
Preferably, the full-automatic resistance welding machine of above-mentioned round lithium ion battery welding tooling, said lock handle is 2 groups with its corresponding quantity that is connected the position.
Preferably, the full-automatic resistance welding machine of above-mentioned round lithium ion battery welding tooling, the groove that is shaped as reception shape to be welded or has restriction nickel strap two-dimensional activity function of said stopper slot bottom surface.
The utility model structure has following beneficial effect:
The full-automatic resistance welding machine of above-mentioned round lithium ion battery welding tooling; Effectively be fixed up in the position of nickel strap and electric core; Then adopt full-automatic resistance welding machine just can accurately electric core and nickel strap be welded; Avoid the generation of artificial jitter phenomenon in welding process, accurate positioning has prevented the appearance of situation such as leakage is welded, weldering is quick-fried; Simultaneously improve production efficiency greatly, reduced the scrappage of electric core combination, practiced thrift production cost, and appearance looks elegant, high conformity is fit to requirements of large-scale industrial production.
Description of drawings
Fig. 1 is the structural representation of the full-automatic resistance welding machine of the said round lithium ion battery of the utility model welding tooling.
Among the figure: 1-counterdie 2-patrix 3-lock handle 4-connects the position
The specific embodiment
For further specifying the utility model, existing conjunction with figs. is set forth in detail:
As shown in Figure 1; The full-automatic resistance welding machine of said round lithium ion battery welding tooling; Fixedly form through lock handle 3 by patrix 2 and counterdie 1; Said lock handle 3 is fixed on a side of counterdie 1, and patrix 2 is provided with and is used for being fixedly coupled position 4 with lock handle 3, and wherein lock handle 3 is 2 groups with its corresponding quantity that is connected position 4; It is identical or slightly be shallower than the stopper slot of nickel strap thickness to be processed that the inboard of said patrix 2 and counterdie 1 is provided with thickness, and the stopper slot bottom surface has and nickel strap corresponding shape to be welded.
On concrete the application, counterdie 1 is kept flat, corresponding moulding nickel strap is put into the stopper slot of counterdie 1, the round lithium-ion electric core group that will combine is again put into counterdie 1; Cover patrix 2, with lock handle 3 lockings, form an integral body, the counterdie 1 that nickel strap will be housed then makes progress; Put into full-automatic resistance welding machine welding stage assigned address, start automatic welder(welding machine), begin welding according to pre-set program, wait welding to accomplish after; Patrix 2 and counterdie were opened in 1 minute, taken out round lithium-ion electric core group, patrix 2 is put down face, in the stopper slot of patrix 2, put into corresponding moulding nickel strap according to compound mode; And then round lithium-ion electric core group put into patrix 2, and cover counterdie 1, with lock handle 3 lockings, then patrix 2 is upwards placed; Put into full-automatic resistance welding machine assigned address, the starting resistance welding machine welds according to predefined program, after welding is accomplished; Patrix 2 and counterdie were opened in 1 minute, taken out round ion-conductance core group, so just accomplished the full-automatic welding of whole round ion-conductance core group.
It is thus clear that; The full-automatic resistance welding machine of round lithium ion battery according to the invention welding tooling can be preferably with electric core and nickel strap location and fixing; So full-automatic resistance welding machine just can be according to the parameter of setting; Accurately electric core and nickel strap are coupled together, can be because of nickel strap location not, the quick-fried problem of point that reason such as nickel strap is unsettled causes electric core when resistance welded, to cause.
The above only is the preferred implementation of the 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 improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
