Accompanying drawing explanation
Fig. 1 is the structural representation of the lithium ion battery steel ball sealing device of the utility model specific embodiment.
Fig. 2 is the end view of the ion battery steel ball sealing device of the utility model specific embodiment.
Embodiment
The utility model provides lithium ion battery steel ball sealing device, for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes below to the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 is the specific embodiment of lithium ion battery steel ball sealing device of the present utility model.
As shown in Figure 1, described steel ball sealing device comprises: mounting seat 100, the battery stationary fixture 200 of lithium ion battery fixedly to be sealed and can control the pressure bead seal mouth mechanism 300 sealing the steel ball degree of depth.
The envelope steel ball degree of depth (that is degree of steel ball extruding) of described pressure bead seal mouth mechanism 300 can be adjusted according to the production of different battery, technological requirement etc., arranges.Certainly, the described control envelope steel ball degree of depth can be achieved by any suitable mechanical structure.
Described mounting seat 100 comprises line slideway 110 and height regulating rod 120, and described battery stationary fixture 200 is connected with mounting seat 100 by line slideway 110.Described battery stationary fixture 200 can linearly move by guide rail 110, adjusts its particular location.
As shown in Figure 1, described pressure bead seal mouth mechanism 300 is connected with mounting seat 100 by the height regulating rod 120 perpendicular to line slideway 110.Described pressure bead seal mouth mechanism 300 with between height regulating rod 120 for being flexibly connected, can move up and down along height regulating rod 120.Preferably, vertical groove can be set on described height regulating rod 120.Accordingly, at pressure bead seal mouth mechanism 300, projection is set with height regulating rod junction, is engaged with the mutual of projection by groove, being convenient to pressure bead seal mouth mechanism 300 when moving up and down, keeping the angle between height regulating rod constant.
The concrete course of work is: when lithium ion battery is after injection electrolyte, carry out extrusion process to its shell, in liquid injection port, steel ball is placed accordingly by place, is then positioned in battery stationary fixture 200 and is fixed.According to lithium ion battery actual conditions, adjustment battery stationary fixture 200 and the position of pressing bead seal mouth mechanism 300.The manual pressure bead seal mouth mechanism 300 that promotes extrudes steel ball to the envelope steel ball degree of depth preset, and completes the operation of envelope steel ball.
It is preferred that as shown in Figure 2, pressure bead seal mouth mechanism comprises: pressure pearl bar 310, bindiny mechanism 320, for pressure pearl handle 330 and the spacing screw mandrel 340 of the degree of depth of user's force.
Described pressure pearl bar 310 is connected with pressure pearl handle 330 by bindiny mechanism 320, and declining with the rotation of pressure pearl handle 330 thus extrude steel ball completes steel ball sealing operation.Concrete operation method is: operating personnel rotate pressure pearl handle 330, exerts a force, and make pressure pearl bar 310 decline thus extrude steel ball by bindiny mechanism 320 to pressure pearl handle 330.Pressure pearl handle 330 can be moved by any suitable force saving driving mechanism band dynamic pressure pearl bar 310 be arranged in bindiny mechanism 320.Certainly, described bindiny mechanism 320 also can adopt the bindiny mechanism of existing manual envelope steel ball device.
The spacing screw mandrel of the described degree of depth 340 is arranged between pressure pearl bar 310 and bindiny mechanism 320, is locked between the two, the maximum descending depth of restriction pressure pearl bar 310, thus realizes the control to the envelope steel ball degree of depth, ensures the consistency of envelope steel ball quality.The spacing screw mandrel 340 of the described degree of depth can arrange one or more according to actual needs.The adjustment of sealing the steel ball degree of depth then can be realized by the spacing screw mandrel 340 of the degree of depth changing different length.Such as, when needs increase the envelope steel ball degree of depth (extruding steel ball degree strengthens, and pressure pearl bar 310 descending depth is larger), the spacing screw mandrel 340 of the degree of depth that length is shorter is changed.
Concrete, as shown in Figure 1, described pressure bead seal mouth mechanism 300 also comprises head rod 350, spring 360.Described head rod 350 is fixedly connected in bindiny mechanism.As shown in Figure 2, one end of described pressure pearl bar 310 is the pressure pearl block 311 of extruding steel ball, and the other end is connected with head rod by spring 360.After arranging above-mentioned spring 360, pressure pearl bar 310 has declined after extrusion operation (namely sealing steel ball), under the stretching action of spring, can recover automatically, rise to original position, thus effective raising seals steel ball efficiency.
More specifically, as shown in Figure 1, described battery stationary fixture 200 specifically comprises fixture cover 210, the driving cylinder 230 of battery briquetting 220 and promotion battery briquetting.Described battery briquetting 220 is arranged on the side of described fixture cover 210.In practical work process, be placed on by lithium ion battery to be sealed in fixture cover 210, drive cylinder 230 to promote, briquetting 220 moves, and compresses, the position of fixing described lithium ion battery.The concrete size of described fixture cover 210 can be determined according to held lithium ion battery quantity, general, once can hold 20-40 lithium ion battery or battery core.Adopt the mode that above-mentioned cylinder controls, effectively can improve the upper folder speed waiting to seal lithium ion battery, improve the envelope steel ball efficiency of lithium ion battery.
Certainly, preferably, the detent mechanism of self-contained battery stationary fixture 200 and pressure bead seal mouth mechanism 300 position can be respectively arranged with on described line slideway and height regulating rod.After position has adjusted, the position of self-contained battery stationary fixture 200 and pressure bead seal mouth mechanism 300, has ensured the quality of press seal steel ball.Described detent mechanism can adopt the detent mechanism of existing conventional fixing moving-member, and therefore not to repeat here.
In sum, the lithium ion battery steel ball sealing device that the utility model provides, spacing screw mandrel is additionally set in general manual envelope steel ball device and controls the envelope steel ball degree of depth, effectively ensure that the consistency of product, and the battery stationary fixture adopting cylinder to control, improves the upper folder speed of lithium ion battery.Controlled by the controlled envelope steel ball degree of depth and cylinder, effectively achieve the balance between quality, manufacture efficiency and cost.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, can be improved according to the above description or convert, all these improve and convert the protection range that all should belong to the utility model claims.
