Description

Technical Field

[0002] Photovoltaic welding ribbon is a very important component of solar cell modules and has a wide range of applications. In the manufacturing process of solar panels, photovoltaic welding ribbon is needed to connect the cells to form a complete circuit. Photovoltaic welding ribbon can also be used as a wire in electronic products. Compared with traditional electronic wires, photovoltaic welding ribbon has better conductivity and corrosion resistance, which can effectively improve the performance and life of the product.

[0003] Among them, the photovoltaic welding ribbon needs to be cut according to the use requirements during production. Since the photovoltaic welding ribbon is wound on a winding wheel, when the photovoltaic welding ribbon is separated from the winding wheel, the photovoltaic welding ribbon will be deformed into an arc shape.

Since the photovoltaic welding ribbon is in a moving state when cutting, the uneven external force applied can easily cause damage to the surface coating of the photovoltaic welding ribbon. Therefore, we propose a straightening device for a photovoltaic welding ribbon cutting machine. Utility Model Content

The cutter 523 is processed with a bevel blade. The strip plate 522 is driven to move by the contraction of the hydraulic cylinder 521, and then the strip plate 522 drives the cutter 523 to move downward, thereby realizing the cutting of the photovoltaic welding strip.

[0060] Working principle:

[0061] First, install the carrier 21 at the tail end of the cutting machine body 1, use the bolts 32 to fix the mounting bracket 31 on the carrier 21, place the take-up wheel 43 with the photovoltaic welding tape installed in the bracket 42, then pass the photovoltaic welding tape between the first roller 22 and the second roller 233, adjust the use height of the mounting plate 232 through the support rod 231, then use the positioning pin 234 to fix the support rod 231 in the carrier 21, and then adjust the height of the second roller 233, straighten the photovoltaic welding tape through the limiting of the second roller 233 and the first roller 22, and then drive the fixing plate by moving the connecting rod 331 upward 334 is used to lift the round roller 34 to its height, and the nut 332 is used to limit the connecting rod 331.
