Ribbon transfer device for solar cell ribbon bonding system

Abstract

The invention relates to welding strip delivering device of a solar cell welding strip bonding system. The device comprises an upper horizontal delivering part (50), which is used to horizontally feed welding strips to a welding strip supplying part (10), which is curved and supplies welding strips; a cutting part (20), which is used to cut the welding strips delivered by the upper horizontal delivering part (50); a vertical delivering part (30), which is used to downwards deliver the horizontally fixed cut welding strips; a lower horizontal delivering part (70), which is used to deliver the welding strips from the vertical delivering part (30) to a bonding position; a solar cell loading part (80), which is used to move solar cells to the bonding position; a bonding part (60), which is used to bond the solar cells and welding strips in the bonding position; and a vacuum generating part (40), which is used to supply vacuum pressure to the vertical delivering part (30) so as to prevent deformation of the welding strips during the process when the welding strips are cut or removed from the upper horizontal delivering part (50).

Description

Technical field [0001] The present invention relates to a ribbon transfer device for a solar cell ribbon bonding system, and more specifically, a ribbon for a solar cell ribbon bonding system that improves the straightness of the ribbon to be bonded to a solar cell and increases the process speed. Transfer device. Background technique [0002] Generally speaking, solar cells used for solar power generation can generate electricity if they start from silicon or various compounds into the form of solar cells. However, one battery cannot obtain sufficient power, so each battery should be connected in series or parallel, and the connected state is called a "solar module". [0003] The solar module is composed of a back sheet, solar cells, ribbon, ethylene-vinyl acetate copolymer (EVA), and glass. The bottom plate is the material that is placed at the bottom of the module and mostly uses TPT (Tedlar / PET / Tedlar) type, and the solder ribbon is used as a path for flowing current, so the ...

Problems solved by technology

[0007] The structure of the above-mentioned registered patent No. 10-1113027 can prevent the displacement of the welding ribbon or a part of the bending when the conventional loader is released from clamping, but if the welding ribbon is pulled by the loader and the pin is used to If the clamp is released even when it is pressed to contact the solar cell, a part of it can be bent

[0008] In the section where the bending occurs, it will not completely adhere to the bus line of the ribbon tube solar cell, so there will be a problem of increasing the resistance

[0009] In addition, after the loader moves to the side of the ribbon supply part that supplies the ribbon, the process of clamping the ribbon and moving horizontally to the original position again, the process of fixing the ribbon with the pin, and the process of releasing the clamp should be performed in order. process, so there is a problem that the time to place the ribbon on the surface of the solar cell is delayed and the productivity is reduced

[0010] In particular, after the loader transfers the ribbon to the upper part of the solar cell, and then moves to the ribbon supply side after the bonding is completed, there is a problem that the supply of the ribbon is delayed and productivity is lowered.
