Composite label and photovoltaic module manufacturing method using label

Abstract

The invention provides a composite label for a photovoltaic module. The composite label comprises a non-transparent label and a transparent label, the non-transparent label comprises a non-transparentsurface material and an adhesive layer arranged on one side of the non-transparent surface material, and the non-transparent label adheres to base paper; the transparent label comprises a transparentsurface material and an adhesive layer arranged on one side of the transparent surface material, and the transparent surface material adheres to the base paper. During manufacturing of the photovoltaic module, the composite label is used, automatic online labeling can be carried out by adopting an automatic labeling device, labor is saved, and the labeling working efficiency can be greatly improved. Besides, whole-process tracing of the photovoltaic module can be achieved through only one label in the whole manufacturing technology. Mark reading on the front and back sides of a double-sided glass assembly can be achieved only through one label.

Description

technical field [0001] The invention relates to the field of photovoltaic module manufacturing, in particular to a composite label used in the manufacture of photovoltaic modules and a method for manufacturing a photovoltaic module using the label. Background technique [0002] Due to the non-renewability of fossil energy, people have been looking for suitable new energy to replace the exhausted fossil energy. Among them, photovoltaic modules can convert the sun's light energy into electrical energy, and have attracted much attention. [0003] At present, the production of photovoltaic modules, that is, solar panels, includes the following processes in turn: laying the first layer of EVA film on the panel glass; then placing the battery sheet and bus bar; welding the bus bar and battery sheet; laying the second layer of EVA Adhesive film; Lay the back sheet; Insert the module label in reverse and stick it on the bus bar; Then perform high-temperature vacuum lamination to en...

Problems solved by technology

[0006] In addition, since the EVA film is a layer of hazy low-transmittance film at room temperature, in the existing process, the label is between two layers of EVA film, and the EVA film is a low-transmittance film before high-temperature lamination, so in The outside of the glass is invisible, and the label cannot be read before high-temperature vacuum lamination, so it cannot be used for traceability of the production process. If the entire production process needs to be traced, an auxiliary label needs to be attached to the outside of the glass in the first step, and removed after the production process

[0007] In addition, because the label is inserted between the panel glass and the bus bar and pasted on the bus bar, this operation is too delicate and can only be done manually. The label can be inserted and pasted by tweezers, which cannot be automated.
