Tin-plated copper belt with identification mark

Abstract

The invention belongs to the technical field of mechanical equipment, particularly discloses a key part in a solar battery piece component, and relates to a tin-plated copper belt with an identification mark. The tin-plated copper belt comprises a copper material substrate and a tin-plated layer, and the outer surface of the copper material substrate is evenly coated with the tin-plate layer. The identification mark is arranged on the tin-plated layer. The thickness of the identification mark is smaller than that of the tin-plated layer. The identification mark is characters or patterns or a combination of characters and patterns. The identification mark is arranged on the surface of the tin-plated copper belt, the features such as the manufacturer and the model number of the tin-plated copper belt can be effectively identified, and errors during a tin-plated copper belt selecting process are avoided.

Description

technical field [0001] The invention relates to a tin-coated copper strip with an identification mark, in particular to a key component in a solar cell assembly, and belongs to the technical field of mechanical equipment. Background technique [0002] Solar cells are a very promising new power source, which has three advantages of permanence, cleanliness and flexibility. Solar cells have a long service life. As long as the sun exists, solar cells can be used for a long time with one investment; compared with thermal power generation and nuclear power generation, solar cells will not cause environmental pollution; A medium-sized power station of 10,000 kilowatts, as small as a solar battery pack for one household, is unmatched by other power sources. [0003] Cells, which are the core of photovoltaic modules, have become the focus of the entire photovoltaic industry. Tin-coated copper strips play an important role in connecting cells in modules. Existing tin-coated copper s...

AI Technical Summary

Problems solved by technology

Existing tin-coated copper strips often have a smooth surface structure, lacking identification marks on the surface, and many tin-coated copper strips are put together in the workplace, so that the phenomenon of mishandling and using the wrong ones often occurs in applications, and the photovoltaic module The effective service life is 25 years in outdoor natural conditions. During this period, anti-traceability documents, forms, labels, and nameplates are difficult to effectively save and dispose of. It is even more difficult to quickly and effectively identify the source of the product at the dealer’s end and the customer’s terminal. For traced product sources, often It is only the product terminal, the traceability of structural parts and components is even more difficult, and the particularity of using it as a photovoltaic module (the front needs to have good light transmittance and no shading surface) makes it impossible to print the front of photovoltaic modules on the market And pasting your own company nameplate, LOGO or slogan, the publicity and marking of the production company cannot be as effective and intuitive as conventional products, so it is urgent to develop an indestructible identification mark that can be visually confirmed and accurately identify the manufacturer, model and other indicators
