Vision-based detection mechanism is set to the bottom of rack 10 and has vision-based detection platform.Vision-based detection mechanism utilizes high-resolution
The industrial camera of rate carries out processing of taking pictures to the grid line of solar battery sheet and interconnecting electrode by the way of taking pictures, with detection
Whether the solar battery sheet to feeding has defect.Vision-based detection mechanism calculates the position of solar battery sheet simultaneously, and will
Position correction data are sent to grasping mechanism 43, are accurately turned solar battery sheet according to amendment data convenient for grasping mechanism 43
Move to welding platform 21.
Grasping mechanism 43 has sucker.Grasping mechanism 43 grabs solar battery sheet from the feeding gaily decorated basket 41 and makes solar energy
Cell piece is with the transfer of light-receiving surface state directed downwardly in the vision-based detection platform of vision-based detection mechanism, and vision-based detection mechanism is from solar-electricity
It is taken pictures to the light-receiving surface of solar battery sheet below the piece of pond to carry out defects detection and position detection and send the data to
Grasping mechanism 43.Solar battery sheet is transferred to the welding platform of each series welding platform group 20 according to data by grasping mechanism 43 again
21。
Solar battery sheet feeding device 40 further include slightly compared with translation stage, defects detection mechanism, scaling powder spraying mechanism.
Before solar battery sheet is transferred to the vision-based detection platform of vision-based detection mechanism 42, grasping mechanism 43 is first by solar battery
Piece, which is transferred to, slightly sets thick calibration compared with the enterprising line position of translation stage.Defects detection mechanism carries out defects detection to solar battery sheet.
Scaling powder spraying mechanism sprays scaling powder to the interconnecting electrode of solar battery sheet, to facilitate subsequent welding.
Optionally, the quantity of series welding platform group 20 is two, and two series welding platform groups 20 are installed on rack 10 in parallel
Both sides.Obviously, the quantity of track 11 is correspondingly also two, and two tracks 11 are distributed in the both sides of rack 10.Two series weldings
Platform group 20 is by the same welding feeding device 30 and solar battery sheet feeding device 40 come respectively to welding and the sun
It can cell piece progress feeding.
Optionally, the quantity of series welding platform group 20 is four, four series welding platform groups 20 with two for one group in parallel side by side
Ground is installed on the both sides of rack 10.Obviously, the quantity of track 11 is also four, and four tracks 11 are divided with two for one group in parallel
It is distributed in the both sides of rack 10.Each group of two series welding platform groups 20 are brought by the same welding feeding device 30 come butt welding
Row feeding.And since a solar battery sheet feeding device 40 is enough to supply four track feeding demands, four series weldings
Platform group 20 carries out feeding to solar battery sheet by the same solar battery sheet feeding device 40.Solar battery
Piece feeding device 40 is located between two groups of series welding platform groups 20, i.e., two groups of series welding platform groups 20 are by solar battery sheet feeding device
40 separate.
Heating device 50 is set to rack 10 and is heated at high temperature for solar battery sheet, so that welding and solar energy
The interconnecting electrode of cell piece welds together, to realize series welding.When operation, series welding platform group 20, which is successively alternately moved to, to be added
The heating region of thermal 50, heating device 50 carry out heating welding to the solar battery sheet in each series welding platform group 20,
So that solar battery sheet series welding is together.
Optionally, the quantity of heating device 50 is multiple and consistent with the quantity of series welding platform group 20, heating device 50 1
One accordingly carries out heating welding to the solar battery sheet in each series welding platform group 20.That is, each series welding platform
Group 20 accordingly configures a heating device 50 and carrys out heating solar cell piece, since heating welding process needs to expend a timing
Between, the problem that multiple heating devices 50 are avoided that multiple series welding platforms 20 are crowded, heating needs to wait for time-consuming is set.

(Electroluminescent) detection device (not shown).Wherein EL detection device is the electricity using solar battery sheet
Photoluminescence principle, using the near-infrared image of high-resolution infrared camera shooting solar battery sheet, therefore, it is determined that solar energy
The welding defect of cell piece, such as rosin joint, crack, sliver etc. are bad, and welding quality can clearly be effectively detected.EL detection dress
It sets and is made of mechanisms such as high definition camera, energization clamping device, camera bellows, external-connection displayer, controllers.And manually visualize detection
Mainly the defects of showing money or valuables one carries unintentionally, deviate of detection welding.The battery strings for setting length are completed after welding, and welding platform 21 moves to down
Discharge position, blanking device successively grab the solar battery sheet in the welding platform 21 of each series welding platform group 20 to EL inspection in turn
Device is surveyed to detect welding defect, while the welding platform 21 of series welding platform group 20 returns to initially upper discharge position and starts next round and adds
Work.After EL is detected, successively crawl solar battery sheet turns over blanking device to predetermined position and by solar battery sheet in turn
Turn predetermined angular for manually visualizing detection.Manually by " finished product " that has determined or " bad " battery strings be respectively implanted it is different under
In magazine.
It when series welding platform group 20 and track 11 are correspondingly multiple, such as is two or four, blanking device (figure
In be not shown) and EL (Electroluminescent) detection device can be one, the series welding platform group on multiple tracks 11
20 share a blanking device and EL (Electroluminescent) detection device.
It, can be in time to production operation and technique research and development personnel's feedback device welding surface and string by the way that EL detection device is arranged
The quality of solder joint and the solar battery sheet for sub-electing abnormal quality in time.
It is worth noting that, if the subsequent solar battery sheet multi-track series welding system design and manufacture and operation more
Add and stabilize, the frequency that welding quality occurs extremely is seldom, and EL detection system can in time be removed, to save space.
Particularly, in this present embodiment, the solar battery sheet multi-track series welding system can realize using flat welding and
Shape welding brings series welding solar battery sheet, namely realizes the feeding of shape welding band and the positioning pair with solar battery sheet
It is quasi-.Wherein the quantity of welding feeding device 30 is two, and one of welding feeding device is flat welding feeding device 30A,
Another welding feeding device is shape welding band feeding device 30B.
Shape welding band feeding device 30B is used to carry out feeding to shape welding band, i.e., shape welding band is carried to welding platform
21 so that shape welding band and solar battery sheet wherein one side interconnecting electrode alignment.For convenience, be described below only with
Shape welding band W as an example, illustrates that the present invention carries out the principle of feeding to triangle welding using triangle welding.Shape welding band
Feeding device 30B includes the movement of handgrip 31B and first mould group 32B.
