Technical field
This utility model belongs to technical field of solar, more particularly, to a kind of production equipment of solar battery sheet, specifically
Say be a kind of printing dereliction grid cell piece front electrode equipment.
Background technology
Global fossil energy crisis and environmental pollution have promoted the fast development of photovoltaic industry.A few days ago, with crystal silicon electricity
Assembly 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 becomes the main restricting factor of its development.In terms of cost of manufacture, the material in occupation of about 60 70% for the silicon materials
Cost, the consumption of silver paste is in occupation of the material cost of about 20-30%.The bold proposition of forefathers no main gate line technology, is to fall
This target inexpensive serious hope the most eager, and this technology also contributes to increase the effective illuminating area of cell piece, improves and sends out
Electricity.But some of which technological difficulties have contained the development of no main grid, such as 1. Chinese patent《The silion cell of no 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 no
Main grid line technology butt welding machine requires too harsh, thus improve equipment cost；3. Lin Jianwei《No main grid, the high efficiency back of the body connect
Tactile solar energy module, assembly and preparation technology》[the patent No.：CN 104282788 A] there is whole battery sheet material and group
The technological innovation of part material, and technique and quality standard very immature.
Cell piece printing screen plate this on the one hand, many patents have some of oneself to illustrate viewpoints both at home and abroad, 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 is rounded with the junction of secondary grid line, and contact area therefore between the two increases
