S1 manually or by automation equipment by quasi- one group of battery core for being assembled into battery core module is positioned on the substrate 411, connects
The driving device 4132 in the fixed fixture 41 starts, and one group of battery core 21 is pushed at the locating part 412 and is limited, is connect
In the fixed fixture 41 startup of cylinder 4142 makes two pushing plates 3141 be moved to 21 direction of the core, and from two
A opposite reversed top that battery core is clamped and fastened on to four strip-shaped holes 4111, while in four strip-shaped holes 4111
Two short sides close to battery core positioned at outside.
Then, the conveying device 42, which starts, is moved to 41 entirety of the fixed fixture from one end of the guide rail 421
BUSBAR is positioned on the electrode surface of one group of battery core by manual or automaticization equipment, then the conveying by the other end here
The fixed fixture 41 is moved integrally the lower section to the locating detent 11 by device 42 again, and makes one group of telescopic mast 12 and the base
Strip-shaped hole 4111 on plate 411 corresponds to.
Also, the battery core module for being placed with BUSBAR is moved to below the locating detent 11 and is passed through in conveying device 42
When described image harvester 8, described image acquisition 8 is actuated for Image Acquisition, and determines BUSBAR's by control device
Whether placement location accurate and welding position.
S2, then, the jacking apparatus 16 in the anti-rosin joint device 1 drive the top plate 15 to be lifted, described solid to make
Determine the whole lifting of jig 41 and the BUSBAR to one group of battery core is contacted and fitted closely with the locating detent 11；Then the gas
The startup of cylinder 110 makes the mounting plate 19 be lifted, to which telescopic mast 12 described in one group contacts with the bottom of one group of battery core and makes bullet
Spring 122 compresses, if there are gaps between the electrode surface and BUSBAR of battery core at this time, then anti-work of the telescopic mast 12 in spring 122
It is firmly lower that the electrode surface of battery core can be driven to be bonded as possible with BUABAR, finally realize each battery core electrode surface and BUSBAR it is tight
Patch.
And before or while the cylinder 110 jacks, the fixed fixture 41 can also be made slightly to unclamp to one group
The clamping of battery core, consequently facilitating telescopic mast 12 is finely adjusted.
S3, finally, the mobile mechanism 32 drive generating device of laser 31 and rechecking device 9 to be moved on battery core module
Side, rechecking device 9 starts determines the horizontal position of BUSBAR, whether height is accurate and determines by Image Acquisition and laser positioning
Going out each welding position, two group welding positions are compared control device, are confirmed whether to meet welding requirements, when composite demand,
Pass through the welding of the movement 31 continuous electrode surface for carrying out BUSBAR and battery core of generating device of laser.Certainly in other implementations
In example, the battery core module and BUSBAR that are located therein can also be pushed up preceding activity by rechecking device in anti-rosin joint device 1.
After the completion of welding, the welder 3 is moved at another battery core module pipeline with to be welded, the anti-void
Welder counteragent resets, and the battery core module 20 after then the battery core module pipeline 4 will weld is moved to initial bit
Set carry out blanking.
Still there are many embodiment, all technical sides formed using equivalents or equivalent transformation by the present invention
Case is within the scope of the present invention.
