Description
Technical field
The utility model relates to a kind of jig for solar battery sheet, is a kind of aid that uses in the manufacture of solar cells process, belongs to field of solar energy.
Background technology
Conventional fossil fuel is approach exhaustion day by day, and in existing sustainable energy, solar energy is undoubtedly a kind of cleaning, the most general and most potential alternative energy source.Therefore, solar cell has obtained the attention of countries in the world, has also obtained at present great development.
In the prior art, solar cell is obtained by the welding welding by the multi-disc solar battery sheet, and welding process generally realizes at jig.Existing jig mainly comprises a heating platform, and this heating platform has heating function.
During use, the monolithic battery sheet is placed directly on the heating platform, then welds with flatiron.Yet, owing to have 200 ~ 300 ℃ the temperature difference between the high temperature of flatiron and the heating platform, because expanding with heat and contract with cold effect, buckling deformation can occur in cell piece in welding process, this has not only brought great inconvenience to welding operation, and because buckling deformation, between cell piece and the heating platform phase mutual friction can occur in welding process, this can cause the thin grid line on the cell piece to wear and tear, and has reduced the performance of cell piece.
Summary of the invention
The utility model purpose provides a kind of jig for solar battery sheet.
For achieving the above object, the technical solution adopted in the utility model is: a kind of jig for solar battery sheet, comprise a heating platform, and also comprise vacuum extractor and tracheae;
Evenly be provided with at least 10 vacuum holes on the described heating platform, vacuum hole is communicated with described vacuum extractor by tracheae;
The diameter of described vacuum hole is 1 ~ 2 mm;
During vacuum extractor work, the pressure that bears on the solar battery sheet is 40 ~ 100 KPa.
Above, described heating platform has heating function, and in the course of the work, heating platform can heat.
The vacuum hole that the utility model has quantity not wait according to shape and the size distribution of cell piece on platform, after placing cell piece by locating piece, open vacuum extractor, vacuum hole holds cell piece, welding is welded on the cell piece respective electrode, when welding is finished, disconnect vacuum, take off cell piece.
In the technique scheme, also comprise control system and on-off switch.
By the break-make of control system control vacuum, when vacuum is led to (during vacuum extractor work), heating platform adsorbs cell piece by vacuum hole, carries out welding of battery film; When vacuum disconnects, the fetching battery sheet.
In the technique scheme, respectively be provided with a positioning block on the adjacent both sides of described heating platform.
In the technique scheme, be provided with the groove of cooperation on the described heating platform corresponding to the position of main grid line on the solar battery sheet.
The effect of groove is to hold welding, so that other parts of cell piece are close on the heating platform.This is to adopt progressive welding method for cell piece; At heating platform groove being set need to be according to size and the spacing of the main grid line on the cell piece, and than main grid live width, the degree of depth of groove is determined by the thickness of welding, preferably with the welding consistency of thickness.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1, the utility model is provided with vacuum hole at heating platform, by vacuumizing cell piece is held, cell piece is adsorbed on the heating platform, during work, the pressure that bears on the solar battery sheet reaches 40 ~ 100 KPa, thereby the cell piece buckling deformation of having expanded with heat and contract with cold and cause when having prevented cell piece because of welding has reached the purpose that reduces the warpage of cell piece after the manual welding simultaneously.
2, the utility model holds cell piece by vacuumizing, cell piece is adsorbed on the heating platform, prevent the movement of cell piece on heating platform in the welding process, thereby reduced the infringement of the thin grid line on the cell piece that cell piece and phase mutual friction between the heating platform cause.
3, the utility model is simple in structure, is convenient to preparation, and applicability is strong.
