Embodiment
, below will be to required use in embodiment in order to illustrate more clearly of the technical scheme of the utility model embodiment
Accompanying drawing be briefly described, it should be apparent that, drawings in the following description are some embodiments of the utility model, for this
For the those of ordinary skill of field, on the premise of not paying creative work, it can also be obtained according to these accompanying drawings other
Accompanying drawing.
The utility model embodiment provides a kind of cell piece conveying, scribing, series welding integrated equipment, is included in cell piece
The scribing mechanism 60 that is set on transport path, severing machine structure 70, series welding first 90, the work head of scribing mechanism 60 are arranged on cell piece
Back electrode face side, with to the back electrode face for the cell piece for not stopping being fed forward carry out scribing, severing machine structure 70 to draw
Cell piece after piece carries out breaking piece, and series welding first 90 is arranged on the rear of severing machine structure 70 along cell piece transport path, with to electricity
Pond piece and grid line are welded.
Further, the severing machine structure 70 includes rotation platform 711, translation platform 714, rotary drive assembly, rotary flat

Face sets the sorption channel of absorption cell piece, rotary drive assembly connection rotation platform 711, to drive rotation platform 711 with water
Square it is rotated up to for rotating shaft 712, and then drives the half cell piece of the top of rotation platform 711 relative to translation platform 714
On half cell piece be lifted up, realization break piece.
Rotary drive assembly includes rotary cylinder 713, rotating shaft 712, bearing, telescopic end and the rotating shaft 712 of rotary cylinder 713
One end connection, the other end of rotating shaft 712 is connected with the lower surface of rotation platform 711, and rotating shaft 712 rotates relative to bearing.
The laser scribing being typically used for is the high power density laser beam irradiation workpiece using line focus, makes illuminated material
The rapid fusing of material, vaporization, ablation reach burning-point, while blow down melt substance by with the coaxial high velocity air of light beam, so as to
Realization cuts open workpiece.
And the laser for being used for solar battery sheet scribing be using high-energy-density laser in fragile material(Solar-electricity
Pond piece)Surface be scanned, make material is heated to evaporate a sulculus, then apply certain pressure, fragile material will
Split at along sulculus.Controlled fracturing blasting is caused precipitous Temperature Distribution when utilizing laser grooving, is produced in fragile material
Local thermal stress, makes material be disconnected along sulculus.
If the smooth surface of solar battery sheet is positive electrode face laser scribing, because the temperature of laser scribing is high, hold very much
Its electronics P-N junction of destructible, therefore we use laser scribing solar cell back electrode surface, its benefit comprises at least at 2 points,
First, because the back electrode face of solar battery sheet is brushed with aluminium paste, because of the toughness and viscosity of aluminum, compared with solar battery sheet just
The silicon materials of electrode surface are not easy to disconnect, and after laser scribing, first by aluminium lamination, the flowers are in blossom, avoid existing aluminium lamination adhesion when breaking piece
Problem;Secondly, the high temperature action of laser head 61 avoids in aluminium paste layer and back electrode face and directly acts on positive electrode face to silicon chip
The destruction of P-N junction, laser scribing solar cell back electrode surface is so used, is effectively guaranteed the cut-out of cell piece.
