Description
Technical field
The utility model relates to lithium ion battery production technical field, is specifically related to a kind of cylindrical battery welding settings.
Background technology
Cylindrical lithium ion battery is a kind of Large Copacity, high-power battery, and it is mainly used on the bantam such as camera, portable power tool.
Along with the development of modern society, lithium dynamical battery with operating voltage height, energy density is big, security good, weight is light, self-discharge is little, have extended cycle life, the feature such as pollution-free, becomes electromobile gradually, new forms of energy power that medium-and-large-sized energy storaging product uses.
Lithium cell, especially cylinder type lithium battery occupy very big proportion in existing Battery Market, production technique conventionally, and after cylinder type lithium battery carries out flanging, direct Over-The-Counter fills in advance.
In the pack technological process of series of cells, it is necessary to multipair battery carries out parallel connection or series connection, has following technical problem at present: operation trouble, welding efficiency is low, the not good spot welding when number of batteries is many; When same node needs spot welding more than three nickel bands, battery container and lid distortion are relatively big, and the height of battery is difficult to unified, and spot welding effect is not good; When series of cells there being battery cannot mate with other battery, it is very difficult to determine it is the problem of battery in which unit in parallel, and dismantle this battery and whole battery module can be made to be affected; Producing gas in the direct Over-The-Counter pre-charge process of battery core in addition, make core loose, between positive plate and negative plate, gap is bigger than normal, analysis lithium phenomenon easily occurs when charging, and affects passive film (SEI) when battery core is melted into and forms effect.
It is thus desirable to design a kind of new cylindrical battery welding settings.
Summary of the invention
The purpose of this utility model is for above-mentioned Problems existing, there is provided a kind of structure simple, it is possible to have and stable grip function, keep the consistence of cell height, can raise labour efficiency, and improve the cylindrical battery welding settings of the degree of product standardization.
The purpose of this utility model realizes being made up of following aspect:
Cylindrical battery welding settings, it is characterised in that, include the first clamp assembly and the 2nd clamp assembly; Wherein, the side of described first clamp assembly is provided with some the first arc grooves; The side of described 2nd clamp assembly is provided with some the 2nd arc grooves; Described first arc groove and the 2nd arc groove coordinate the accommodating space forming a cylinder type lithium battery, and described first arc groove inwall has offered open holes, and battery is positioned by open holes built with magnet.
In such scheme, described open holes is circular through hole, and its bore near the side of battery is big, and the side bore away from battery is little.
In such scheme, described magnet is cylinder shape, magnet install in open holes after height, lower than the internal surface of the first arc groove.
The utility model structure is simple, it is possible to has and stable grips function, keeps the consistence of cell height, it is possible to raise labour efficiency, and improve the degree of product standardization.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment first clamp assembly structural representation;
Fig. 2 is the upward view of Fig. 1;
In figure, 1 first arc groove, 2 open holess.
Embodiment
For better understanding technology of the present utility model, it is described below in conjunction with drawings and Examples. Following examples describe and are only exemplary and explanatory, the utility model protection domain are not had any restriction.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Consult cylindrical battery welding settings shown in Fig. 1 Fig. 2 and include the first clamp assembly and the 2nd clamp assembly; Wherein, the side of described first clamp assembly is provided with some the first arc grooves 1; The side of described 2nd clamp assembly is provided with some the 2nd arc grooves; Described first arc groove 1 and the 2nd arc groove coordinate the accommodating space forming a cylinder type lithium battery, and described first arc groove inwall has offered open holes 2, and battery is positioned by open holes 2 built with magnet.
In the present embodiment, described open holes 2 is circular through hole, and its bore near the side of battery is big, and the side bore away from battery is little.
In the present embodiment, described magnet is cylinder shape, magnet install in open holes 2 after height, lower than the internal surface of the first arc groove 1.
Protection domain of the present utility model is not limited to the above embodiments, it is clear that the utility model can be carried out various change and distortion and not depart from scope and spirit of the present utility model by the technician of this area. If these are changed and are out of shape in the scope belonging to the utility model claim and equivalent technologies thereof, then intention of the present utility model also comprises these changes and distortion.
