Description
Technical field
The utility model relates to a kind of welder that is used for lithium ion battery, particularly a kind of all side weld welders that are used for lithium ion battery (box hat and aluminum hull).
Background technology
At present, advantages such as lithium ion battery has voltage height, specific energy height, recycles often, memory time is long, not only on portable electric appts, be used widely, and to be widely used in big-and-middle-sized electrical equipment aspect, especially electrokinetic cells such as electric automobile, electric bicycle and electric tool be the present main direction of each macrocell producer development.One big technical problem of existing electrokinetic cell development is exactly its safety issue, thereby all side weld welding sequences are extremely important.The principle of week side weld is to utilize features such as the high-energy of laser, high stability, linearity, with the material instant melting that will weld, allows them again in conjunction with cooling, to reach the purpose with battery case and battery cover sealing.There is following shortcoming in existing frock:
1, the positive and negative terminals of electrokinetic cell and battery cover insulate, so just having materials such as the plastics of some insulation or other resins exposes in the battery case outside, the fusing point of these materials is very low, since they with laser the route of process be vertical, when fluctuation appears in chucking position, these materials will be by laser fusion, thereby is short-circuited, and can directly cause the increase of percent defective;
2, anchor clamps inconvenience when remodeling needs to increase some cushion blocks and solves the drawback of being brought owing to cylinder stroke deficiency, so not only time-consuming but also effort;
3, we know, the focal length of laser is highstrung, in the time of the battery injustice, can produce considerable influence to welding effect; Can produce some welding slags in the welding process, after these welding slags stick on the base plate, will make the run-off the straight of battery the right and left, directly cause focal length to change, cause the battery welding problems such as weak weldering, intrepid, weldering leakage, trachoma to occur;
4, welding tooling does not have corresponding positioner, can waste the plenty of time when regulating frock.
5, according to Principles of Laser, aluminium alloy is 80% to the laser reflectivity of 1.06 micron wave lengths, and vertical reflection can form plasma above the welding position, weaken the laser effective energy, makes welding unstable.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of all side weld welders that are used for lithium-ion-power cell of easy to operate, dependable performance are provided.
The technical scheme that the utility model adopted is for achieving the above object: comprise substrate, base plate, right baffle-plate, right baffle plate, top briquetting, side position briquetting and cylinder; Described substrate is arranged in the perpendicular, and the cross section of substrate is the right angle wedge shape; Fixedly right baffle-plate and right baffle plate on the substrate; Right baffle-plate and inboard, right baffle plate top are fixed in briquetting two ends, described top, and side position briquetting is fixed in the outside, right baffle plate top, and described top briquetting and side position briquetting are provided with the groove that embeds pole and insulator respectively; Right baffle-plate and inboard, right baffle plate bottom are fixed in described base plate two ends, and base plate one side is provided with elongate slot along its length, and base plate opposite side broad ways is provided with U type groove; Cylinder is fixed by elongate slot and base plate.
Cylinder described in the utility model is connected with manual directional control valve.Its hypotenuse of right angle wedge shape section of substrate and vertical edge angle are 5 degree.The substrate bottom is fixed with block, and block is positioned at briquetting below, side position.
The utlity model has following beneficial effect:
1, welder integral inclination 5 degree angles, the angle that is cell plane and horizontal plane is 5 degree, top briquetting, side position briquetting all wrap up pole and megohmite insulant, and what material adopted is the copper high to laser reflectivity, has so just avoided between pole and the battery cover megohmite insulant by the problem of laser burn effectively.
2, by the angle of inclination, changed the angle of laser reflection, reduced of the influence of the plasma of solder joint top formation to laser energy, make welding energy stable.
3, changed the fixed form of cylinder, be provided with an elongate slot on base plate, cylinder is whole so just can move left and right, and in the time of the short battery of welding, only need move to right cylinder integral body, just can solve the problem of cylinder stroke deficiency; Otherwise when welding high battery, only needing cylinder moved to left gets final product.So when production is remodeled, need not to increase cushion block, only need to adjust the fixed position of cylinder, just can satisfy the production demand, improved the efficient of remodeling and adjusting.
4, base plate is improved, processed a U type groove in base plate broad ways (below of welding position), welding slag that when welding produce etc. is directly dropped in the groove after improvement, can not cause that cell thickness changes, and has effectively avoided the variation of laser focal because of welding slag particle etc.;

The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment that foundation the utility model is provided, details are as follows:
As Fig. 1～shown in Figure 3, the utility model comprises substrate 1, base plate 2, right baffle-plate 3, right baffle plate 4, top briquetting 5, side position briquetting 6 and cylinder 9; Described substrate is arranged in the perpendicular, and the cross section of substrate is the right angle wedge shape; Fixedly right baffle-plate and right baffle plate on the substrate; Right baffle-plate and inboard, right baffle plate top are fixed in briquetting two ends, described top, and side position briquetting is fixed in the outside, right baffle plate top, and described top briquetting and side position briquetting are provided with the groove (shown in Figure 4 and 5) that embeds pole and insulator respectively; Right baffle-plate and inboard, right baffle plate bottom are fixed in described base plate two ends; As shown in Figure 6, base plate one side is provided with elongate slot 10 along its length, and base plate opposite side broad ways is provided with U type groove 11; Cylinder is fixed by elongate slot and base plate.
Cylinder described in the utility model is connected with manual directional control valve.As shown in Figure 2, its hypotenuse of right angle wedge shape section of substrate and vertical edge angle are 5 degree.The substrate bottom is fixed with block 7, and block 7 is positioned at briquetting below, side position.
The utility model cylinder model is: CXSM10-30, manually the directional control valve model is: VH301-03.
Elemental motion during operation is in proper order: when cylinder does not move, battery is put on the welding tooling base plate, move directional control valve then, cylinder is moved forward clamp battery (clamping of battery is exactly by cylinder itself), when pulling manual directional control valve, cylinder moves forward, by two dry gas cylinders front portion battery is pushed up to the top briquetting, thereby battery case and battery cover are closely cooperated; Step on pedal then, begin welding.After welding finishes, open directional control valve, cylinder is regained, and takes out battery, and battery is turned over, and the step above repeating is proceeded the welding on another long limit.After long side weld connects and finishes, battery is taken out, stand up on the substrate of side and be close to right baffle plate, when welding, pin battery bottom, battery is promoted forward, its and side position briquetting are closely cooperated carry out minor face and weld with hand.
Above-mentionedly this is used for the detailed description that lithium-ion-power cell carries out with all side weld welding toolings with reference to embodiment; be illustrative rather than determinate; therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
