Feeding and piece arranging device for electric injection furnace

Abstract

The invention discloses a feeding and piece arranging device for an electric injection furnace. The feeding and piece arranging device is characterized in that a first front-back correcting unit, a first left-right correcting unit, a piece taking position conveying line, a second left-right correcting unit and a second front-back correcting unit are sequentially and fixedly installed at the top face of a fixing plate from left to right, and a conveying rail fixing plate is located at the front side of the fixing plate; and a middle conveying line body is fixedly installed on the conveying railfixing plate and located at the front side of the piece taking position conveying line, a silicon wafer conveying line is fixedly installed on the conveying rail fixing plate and located at the frontside of the middle conveying line body, and a temporary storage piece box is installed on the conveying rail fixing plate and located at the left side of the silicon wafer conveying line. The feedingand piece arranging device is simple in structure and stable and reliable in work, the discharging speed is greatly increased, the situation that battery pieces are stacked due to the fact that the battery pieces cannot be conveyed in time is prevented, and extra damage to the battery pieces is avoided while the correction effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of solar cell sheet processing equipment, and in particular relates to a charging device for an electric injection furnace. Background technique [0002] The electric injection method in the production of solar cells can significantly suppress the light attenuation benefit of monocrystalline silicon and polycrystalline silicon solar cells, and has the function of improving the conversion efficiency of solar cells and improving the actual power generation efficiency of the cells. Due to its technical characteristics, the electric injection furnace needs to stack the screen-printed and sintered cells, and add a conductive metal plate to the top and bottom of the stacked cells to passivate impurities and defects through current. One of the key control points of the electro-injection process is how to neatly stack the cells into a stack. The current feeding device on the market has the disadvantages of uneven st...
