Abstract
The utility model relates to a jig, especially to a soft package small cylindrical lithium battery formation special jig which comprises a first jig assembly and a second jig assembly. In the first and second jig assemblies are respectively provided circular arc-shaped grooves which cooperate with each other to form an accommodating space for a cylindrical lithium battery. In one side walls near the opening direction of the circular arc-shaped grooves are provided exhaust discharging outlets which cooperate with each other to form an exhaust groove. By reserving the exhaust groove, the formation special jig in the utility model is first fixed on an electrical core with the exhaust groove directing to the unsealing area of the electrical core so that a passive film (SEI) is formed in the surface of the negative pole when the electrical core is charged and the generated exhaust can be completely discharged out of the unsealing area. The pole pieces of the electrical cores are made fastened when the electrical pole is undergoing formation, which guarantees the passive film forming effect. And when the electrical core in the utility model is charged, the phenomenon of lithium evolution is unlikely to happen, which lays a solid foundation for the subsequent work performance of the electrical core.
Description
Technical field
The utility model relates to a kind of anchor clamps, and especially a kind of flexible package small column lithium battery changes into special fixture.
Background technology
According to the existing production technology, the direct Over-The-Counter preliminary filling of flexible package small column lithium cell of changing into.But there is defective in original flanging technology:
1. the direct Over-The-Counter precharge of electric core forms passivating film (SEI) on the negative terminal surface when formation charging, and produce gas, influences semicylinder aluminum-plastic composite membrane shape and outward appearance.
2. produce gas in the direct Over-The-Counter pre-charge process of electric core, make the volume core loose, the gap is bigger than normal between positive plate and the negative plate, the time is prone in charging and analyses the lithium phenomenon, and passivating film (SEI) forms effect when influencing electric core and changing into.
Summary of the invention
The purpose of this utility model provide a kind of assurance semicylinder aluminum-plastic composite membrane shape and outward appearance unaffected, and avoid analysing the flexible package small column lithium battery that the lithium phenomenon takes place and change into special fixture.
To achieve these goals, the utility model adopts following technical scheme:
It comprises first clamp assembly and second clamp assembly, one side of described first clamp assembly is provided with first arc groove, one side of second clamp assembly is provided with second arc groove, described first arc groove and the second arc groove relative engagement form the accommodation space of a cylindrical lithium battery, the sidewall of opening direction one side of described first arc groove is provided with first exhaust port, the sidewall of opening direction one side of described second arc groove is provided with second exhaust port, described first exhaust port and second exhaust port formation air discharge duct that matches.
Preferably, described first clamp assembly and second clamp assembly are strip cuboid block structure.
Preferably, described first arc groove and second arc groove are the semicircular arc groove.
Reserve air discharge duct during flexible package small column lithium battery Special Clamps Design of the present utility model, to change into earlier on the fixing electric core of special fixture, and the air discharge duct on the anchor clamps do not sealed the zone towards electric core, when formation charging, form passivating film (SEI) on the negative terminal surface, and generation gas can be discharged envelope zone fully; And special fixture closes and is fixed on the electric core when changing into, electric core is adjacent between the pole piece when changing into, passivating film (SEI) forms effect when guaranteeing that electric core changes into, and is difficult for forming during the charging of electric core and analyses the lithium phenomenon, for electric core follow-up work performance guarantees to lay the foundation.

Fig. 3 is the utility model embodiment first clamp assembly and the second clamp assembly fit structure schematic diagram.
Embodiment
As depicted in figs. 1 and 2, the flexible package small column lithium battery special fixture of present embodiment comprises first clamp assembly 1 and second clamp assembly 2, one side of described first clamp assembly 1 is provided with first arc groove 11, one side of second clamp assembly 2 is provided with second arc groove 21, described first arc groove 11 and second arc groove, 21 relative engagement form the accommodation space of a cylindrical lithium battery, the sidewall of opening direction one side of described first arc groove 11 is provided with first exhaust port 12, the sidewall of opening direction one side of described second arc groove 21 is provided with second exhaust port 22, described first exhaust port 12 and the second exhaust port 22 formation air discharge duct that matches.
In order to make first clamp assembly 1 and second clamp assembly 2 fixing easily, be convenient to the stable cooperation of the two, described first clamp assembly 1 and second clamp assembly 2 are strip cuboid block structure.
For the electric core with flexible package small column lithium battery closely cooperates, described first arc groove 11 and second arc groove 21 are the semicircular arc groove, and the cross-sectional periphery of the cross-sectional periphery of the column accommodation space of its composition and cylinder type lithium battery electricity core equates or be slightly less than the cross-sectional periphery of the electric core of cylinder type lithium battery.
The length of exhaust port groove=electric core length-10mm; The width of exhaust port groove is 〉=8mm.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
