Problems solved by technology
However, when this type of ribbon is automatically serially welded, it is difficult for the equipment to identify the starting position of the sawtooth section and the smooth section, resulting in the part of the ribbon that should have been welded on the upper surface of the battery sheet being stretched to the lower surface of the battery sheet for welding, or originally The smooth section that should be welded on the lower surface of the cell is stretched to the upper surface of the cell for welding, both of which will reduce the absorption of light by the reflective surface of the ribbon, thereby reducing the power of the battery assembly

Embodiment Construction
[0042] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0043] In order to achieve the purpose of the present invention, in some embodiments of a segmented dot embossed welding ribbon and its photovoltaic module and preparation method,
[0044] Such as Figure 1-4 As shown, the segmented embossed welding ribbon is provided with a plurality of serrated surfaces 2 and a plurality of smooth surfaces 3 on the surface of the welded ribbon 1, and the smooth surfaces 3 and the serrated surfaces 2 are arranged alternately. A circular concave point 4 is provided at the starting end of the serrated surface 2 , half of the circular concave point 4 is set at the starting end of the serrated surface 2 , and half is set at the ending end of the smooth surface 3 . The dimples 4 can also be in other shapes, and there is no specific requirement that the diameter of the dimples range between 0.1-1.3mm. The racks ...

The invention discloses a segmented dotting and embossing welding strip, a photovoltaic assembly and a manufacturing method. The surface of the welding strip is provided with at least one sawtooth surface and at least one smooth surface, and the starting end of each sawtooth surface is provided with a concave point. According to the invention, series welding equipment is facilitated to automatically recognize the starting end of the sawtooth surface and the smooth surface, and thus the welding efficiency is improved.
Description
technical field [0001] The invention relates to a welding ribbon in the field of photovoltaic products, in particular to a segmented embossed welding ribbon, a photovoltaic module and a manufacturing method thereof. Background technique [0002] At present, the surface of the photovoltaic ribbon is mostly smooth and flat. Such a ribbon is conducive to welding with the battery sheet, but the sunlight irradiated on the surface of the flat ribbon is completely reflected, which reduces the absorption of solar light by the battery module. For photoelectric conversion The improvement of efficiency and cell power has a great influence. [0003] There is also a part of the sawtooth surface welding strip, and the surface of the welding strip is provided with at least one serrated section and at least one smooth section. However, when this type of ribbon is automatically serially welded, it is difficult for the equipment to identify the starting position of the sawtooth section and t...
