Description
Technical field
The invention belongs to technical field of solar, more particularly to a kind of production equipment and process of solar battery sheet, tool
Saying for body is a kind of equipment and technique for printing dereliction grid cell piece front electrode.
Background technology
Global fossil energy crisis has promoted the fast development of photovoltaic industry with environmental pollution.A few days ago, with crystal silicon electricity
Component based on the piece of pond occupies more than the 80% of global photovoltaic module market；Crystal-silicon battery slice is developed so far, its cost of manufacture
And generated energy turns into the main restricting factor of its development.In terms of cost of manufacture, material of the silicon materials in occupation of about 60-70%
Cost, the material cost of the dosage of silver paste in occupation of about 20-30%.The bold proposition of forefathers is to drop without main gate line technology
The most eager serious hope of this inexpensive target, and this technology also contributes to increase the effective illuminating area of cell piece, improves hair
Electricity.But some of which technological difficulties have contained the development without main grid, such as 1. Chinese patent《Silion cell without main gate line
Piece》[the patent No.：CN201820762U] in there is situations such as welding difficulty is big, welding is easy to fall off；2. Germany Schmid without
Main grid line technology butt welding machine requires too harsh, so as to improve equipment cost；3. Lin Jianwei《Connect without main grid, the high efficiency back of the body
Touch solar energy module, component and preparation technology》[the patent No.：CN 104282788A] there is whole battery sheet material and group
The technological innovation of part material, and technique and quality standard are very immature.
In cell piece printing screen plate this aspect, domestic and international many patents have some of oneself to illustrate viewpoint, but substantially
On all discuss conventional there is main gate line cell piece concentrating.For example, 1. Chinese patent《Photovoltaic cell printing module》[patent
Number：CN202669148U] main gate line that prints out and the junction of secondary grid line it is rounded, therefore contact area between the two increases
Greatly, contact resistance reduces, it is possible to increase photoelectric transformation efficiency.2. Chinese patent《Improved photovoltaic cell printing module》[specially
Profit number：CN202742802U] by aiding in grid line so that when a main gate line breaks down, connect the pair of the failure main gate line
Grid line can be by aiding in grid line to be connected in another main gate line.3. Chinese patent《A kind of enhanced crystal silicon solar electricity
The cell piece of the main gate line of pond four》[the patent No.：CN204792810U] when cell piece prints secondary grid line and broken, still
The collection of electric current can be effectively carried out, greatly reduces the bad ratios of cell piece EL.
The patent of many cell piece printing screen plates has all related to main gate line cell piece, without dereliction grid line cell piece
Half tone occur.Therefore the production equipment for the dereliction grid line cell piece that forms a complete production network also is badly in need of researching and developing.

Platform transports, and thin grid line finishes printing, into next process；
Main grid end and welding enhancing point pressurization injection moulding apparatus are adjusted apart from pending cell piece (2) 1-2mm, first in thin grid
The vertical one end extruding conductive silver paste of line forms 2-6 to main grid end；Then mobile extruding conductive silver paste pipette tips (6),
Brushing pattern mold (5) size is adjusted, extruding conductive silver paste forms welding enhancing point in thin grid line centre position；So far complete
The brushing of main grid end and welding enhancing point, pending cell piece (2) enter next process；
Adjustment enhancing electrical connection effect portion's extruding injection moulding apparatus is apart from pending cell piece (2) 1-2mm, mobile extruding conductive silver paste
Spray gun head (10), brushing pattern mold (9) size is adjusted, optional position extruding conductive silver paste is formed between main grid end
Enhancing electrical connection effect portion.
