Tight plate 152,172 is close and touches the side of corresponding battery 100, at this time first using low pressure for example can be 0.2MPa but
0.2MPa is not limited to position battery 100；
Step S20: the datum plate 32 in height positioning mechanism 30 is linearly moved under the action of actuator 311 and battery
The position that 100 cover board 102 is overlapped, then battery 100 rises under the action of lifting body 60 until touching datum plate 32,
Stop rising；
Step S30: long short side hold-down mechanism 15,17 provides biggish pressure compaction battery 100, specifically, being with cylinder
Example, cylinder for example can be 0.6MPa using high pressure but be not limited to the two orthogonal sides that 0.6MPa compresses battery 100；
Step S40: lifting body 60 declines, and the datum plate 32 in height positioning mechanism 30 is under the action of driving mechanism 31
Linear motion retracts；
Step S50: sealing is realized in the welding carried out between cover board 102 and shell 101.
S60 removes the battery 100 being welded, injects electrolyte into the cavity of battery 100；
The step of S70, repetition S10-S40, it should be noted that be to put the battery 100 for having been injected into electrolyte in this process
Enter in the battery laser welding clamp 200；
Sealing nail 104 is manually placed in liquid injection hole 103 by S80, and rotation and lifting cylinder 51 is rotated and pushed, so that fixed
Position column 53 is aligned and compresses sealing nail 104, and due to 53 leaving certain gaps uncovered by the economic plan of positioning column, barbed portion exposes 104 parts of sealing nail,
Prewelding is first carried out in the place exposed, specifically, in the present embodiment, using the pre- spot welding of laser, then rotation and lifting cylinder
51 revolutions rise, and sealing nail 104 welds together with 102 part of cover board at this time, will not move, it is no longer necessary to press
Tightly, final welding is directly carried out.
Referring to Fig.2, the battery laser welding clamp 200 still further comprises mounting plate 80, the mounting plate 80 is parallel
It is located in the support plate 70 and with the lifting body 60 the same side of the support plate 70, the mounting plate 60 and the branch
Support post 90 is equipped between fagging 70.
Compared with the prior art, battery laser welding clamp provided by the embodiment of the utility model has below beneficial to effect
Fruit:
The cover board 102 and the shell 101 are welded together, and sealing nail 104 is welded on liquid injection hole 103
Together, belong to two techniques, need to design two battery laser welding clamps even equipment, it is provided by the embodiment of the utility model
Two techniques are included in the quantity that a fixture perhaps saves fixture or equipment in equipment by battery laser welding clamp,
The multifunctionality of equipment is realized, to dramatically save cost.
The present invention is not limited to the above embodiments, and the above is preferred embodiments of the present invention, the reality
It applies example and is merely to illustrate the utility model rather than limitation the scope of the utility model, it is noted that for the art
Those of ordinary skill for, without departing from the principle of this utility model, some improvements and modifications can also be made, this
The improvement and modification of a little equivalent forms also should be regarded as including within the protection scope of the present utility model.
