When, the inner surface of two limit plates 151 of each claw 15 is tight with one end outer surface of the long panel 101 of amount side respectively
Patch, to realize long panel and end plates in the pre-determined bit of second direction Y；Meanwhile the lower section holding dog of the clamping jaw 133 1331
In the groove 112 of 11 top surface of pedestal.
Then, two startings of clamping jaw 133 clamp, so that the position in the longitudinal direction of two end plates 102 is positioned, this
When two end plates 102 short sides it is corresponding with the outburst area of long panel respectively.
Then, the power mechanism starting drives the frame 27 whole mobile to 1 direction of fixed fixture, thus
Telescopic mast 21 described in driving one group is moved to the top of the battery core mould group 20, and then, the cylinder axis of the cylinder 24 stretches out, and makes
21 entirety of telescopic mast moves down described in one group and telescopic mast 21 is contacted with the bottom surface of each battery core 201 of battery core mould group 20, this
When, if there are the reaction force that gap, the camber of spring of telescopic mast 21 generate, energy between battery core 201 and the top surface of pedestal 11
Telescopic mast 21 is enough set to apply pressure to the single battery core 201 being in contact with it, to make the electrode surface of the battery core and the top of pedestal 11
Face comes into full contact with, and on the basis of the top surface of pedestal 11 is a flat surface, keeps the bottom surface of one group of battery core 201 concordant, at this time long panel
101 parts contacted with battery core bottom surface can be effectively bonded with the bottom surface of each battery core, there is no gap, so as to avoid
Occurs the case where rosin joint leads to not prison welding when subsequent welding；Meanwhile the meeting of telescopic rod 123 is pushed to the short branch of the long panel in two sides
Apply pressure, be bonded them sufficiently with the bottom surface of battery core mould group, complete after pushing, is stretched described in described one group of power mechanism driving
Contracting column 21 resets, naturally it is also possible to not reset.
Finally, the motor 142 in the translation mechanism 14 is again started up, so that the movable holddown 132 increases to left side
End plates 102 apply pressure, be fixed end plates and battery core mould group, then the cylinder of four fixed mechanisms 120
1202 synchronous averagings, keep four briquettings 1204 mobile to 20 direction of battery core mould group and the briquetting 1204 of the same side with
The long panel 101 of corresponding side is close to, so that long panel 101 and the side of battery core mould group be made to be close to, realizes final fixation.
Certainly, in other embodiments, the above-mentioned process that grips is also possible to other sequences, such as before feeding,
So that the telescopic cylinder 134 of right end is stretched out drives the clamping jaw 133 and claw 15 synchronous mobile to 11 direction of pedestal,
Then the battery core mould group 20 with long panel 101 and end plates 102 is placed on pedestal 11, and makes the end plates of right end
102 are bonded with the fixed briquetting 131, at this point, the right end region of the end plates 102 of right end and long panel 101 is located at right side
In the claw 15 and clamping jaw 133, and the inner surface of two limit plates 151 of the claw 15 long panel with side respectively
101 outer surface is close to, to realize the restriction of long panel 101 and right-hand end panel 102, and makes the two of right-hand end panel 102
Side is concordant with the both side surface of battery core mould group；Then restart the claw 15 and clamping jaw 133 of movable holddown and the other side, specifically
Fixation procedure, which can according to need, to be set, and details are not described herein.
S3 finally, the six-joint robot drives the welder to be moved at the battery core mould group, and passes through image
Acquisition device (not shown) acquires image, to analyze actual position while welding according to preset position while welding, then
The position while welding that the laser soldering device is controlled in setting is welded.
While being welded in a battery core mould group side panel welding accurate positioning device, another battery core mould group side panel
The clamping position that accurate positioning device carries out battery core mould group is welded, after the welding on a station, six-joint robot turns
It moves and is welded on another station, and so on, so as to make full use of the time of welding process to carry out battery core mould group
Clamping position, and then can be improved work pace, improve processing efficiency.
Also, when the six-joint robot is welded, the rotary power unit 5 drives according to actual needs
The angle of the rotation of substrate 3 setting is convenient for welding and makees so that laser soldering device be made to have optimal soldering angle
Industry, meanwhile, it also can make up for it the limited problem of six-joint robot moving range.
Still there are many embodiment, all technologies formed using equivalents or equivalent transformation for the utility model
Scheme is all fallen within the protection scope of the utility model.
