Abstract
The utility model relates to a crystalline silicon solar cell array series welding die plate, which comprises a U-shaped strip plate, transverse limiting pieces and longitudinal limiting pieces. The transverse limiting pieces are fixed at one side of the U-shaped strip plate, the longitudinal limiting pieces are arranged on the upper end surface of the U-shaped strip plate at equal intervals, two grooves corresponding to two mutually connected strips on cell panels are arranged on the upper end surface of the U-shaped strip plate, a cooling cavity is arranged in a lower cavity of the U-shaped strip plate, cooling medium inlet opening and outlet opening are arranged on the cooling cavity, and cooling holes communicated with the cooling cavity are arranged at the bottom of the grooves and at the position corresponding to each cell panel. In the series welding die plate of the structure, while the series welding is performed to the back side of the cell panels, the mutually connected strips on the face side are exactly embedded into the two grooves, and can be well cooled down, therefore the series welding die plate can effectively prevent the defaults of tin stack, rosin joint or separation at the mutually connected strips and frustose patterns on the surface, etc. in the series welding process.
Description
Technical field:
The utility model relates to a kind of series welding masterplate of crystal silicon solar energy battery in the preparation component process.
Background technology:
Crystal silicon solar energy battery needs in the process of preparation assembly with several cell panels with the interconnector series welding together, can produce bigger voltage like this.Its operating process is: earlier with electric iron with an end pressure welding of interconnector on the main grid line of cell panel front, and then with the other end pressure welding of interconnector on the back silver electrode of another cell panel, like this several cell panels are welded successively and are connected as a single entity, must satisfy following requirement behind the cell panel series welding:
1. behind the series welding, the cell panel monomer should equate with spacing between the monomer;
2. the back silver electrode of cell panel front main grid line, cell panel must with the interconnector firm welding, interconnector is neither pounced on tin, does not also have crack performance, the rosin joint that more do not have, obscission;
In order to reach above-mentioned requirements as far as possible, people have moved many brains, must use the series welding masterplate when the cell panel series welding.
The series welding masterplate that generally uses has following two kinds of structures at present.
First kind: as accompanying drawing 1, shown in Figure 2, the series welding masterplate is h type cross section, it is by U-shaped strip plate 1, cross spacing sheet 2, longitudinal spacing sheet 3, handle 5 is formed, the upper surface of U-shaped strip plate 1 is a burnishing surface, longitudinal spacing sheet 3 is arranged on the upper surface of U-shaped strip plate 1 equally spacedly, its quantity is the n-1 sheet, cross spacing sheet 2 is fixed on the side of U-shaped strip plate 1, form h type cross section, n piece cell panel 6 equally spaced spreads on the upper surface of U-shaped strip plate 1, and cell panel 6 is by cross spacing sheet 2 and longitudinal spacing sheet 3 location.
The shortcoming of this series welding masterplate is: be easy to cause interconnector on the cell panel front gate line to produce in welding process and pounce on tin, the width of pouncing on tin is often greater than the width of main grid, thereby increase the shading area, influence the efficient of assembly, do not allow the defective that exists when this is the cell panel series welding.
Second kind: as accompanying drawing 3, shown in Figure 4, it is the modified on first kind of series welding masterplate basis, be easy to generate the shortcoming of pouncing on tin in order to overcome cell panel front interconnector in the serial connection process, offered on the upper surface of U-shaped strip plate 1 two with cell panel on two corresponding grooves 4 of interconnector.
Though overcoming, this series welding masterplate is easy to generate the defective of pouncing on tin in the series welding process, but the silver-colored ashbury metal in the series welding process on positive two interconnectors of cell panel can melt once more, cause rosin joint or disengaging easily, thereby influence the firmness that interconnector combines with battery, cause the assembly disengaging of interconnector and battery in use, influence the long-term efficiency of battery.
In order to prevent rosin joint or disengaging, people are again by reducing gash depth, make in the series welding process that interconnector contacts with channel bottom on the front gate line, like this, the front interconnector is subjected to certain pressure in the series welding process, can avoid producing rosin joint or disengaging, but in actual production process, cause the battery front side interconnector to occur the polygon decorative pattern easily again, influence product quality.
The utility model content:
In order to overcome the deficiency of existing series welding masterplate, the purpose of this utility model provides a kind of crystalline silicon solar array series welding stencil-plate.
It can effectively overcome existing series welding masterplate above shortcomings, guarantee in the series welding process cell panel and interconnector junction neither produce pounce on tin, again can rosin joint or disengaging, the while does not have crack performance yet.
The technical scheme that the utility model is taked is:
Series welding masterplate described in the utility model, comprise U-shaped strip plate, cross spacing sheet and longitudinal spacing sheet, the cross spacing sheet is fixed on a side of U-shaped strip plate, the longitudinal spacing sheet equally spaced is arranged on the upper surface of U-shaped strip plate, its quantity is the n-1 sheet, n piece cell panel equally spaced spreads on the upper surface of U-shaped strip plate, by cross spacing sheet and longitudinal spacing sheet location, offer on the upper surface of U-shaped strip plate two with cell panel on the corresponding groove of two interconnectors, under U strip plate, be provided with cooling chamber in the cavity, on cooling chamber, be provided with cooling medium inlet and outlet, be provided with cooling hole with communicating with cooling cavity corresponding to the position of each cell panel at channel bottom.
The series welding masterplate of this structure, two interconnectors that connect cell panel just in time are bumped in two grooves, cell panel is overleaf series welding the time, owing to feed cooling medium in the cooling chamber, therefore positive last two interconnectors of cell panel can well be cooled off, and can not only prevent effectively that the silver-colored ashbury metal generation at the positive two interconnector places of cell panel from pouncing on tin, rosin joint or disengaging, and the welding surface the polygon decorative pattern can not occur, the surface smoother, the assembly welding quality is more satisfactory.
