Technical Field

[0001] The utility model relates to the technical field of photovoltaic cell screen drying, in particular to a solar cell panel screen printing drying device. Background Art

[0002] Photovoltaic backplane is a key component of solar cell modules. It can be used to protect solar panels and improve the durability and stability of solar cell modules. Photovoltaic backplane can print conductive adhesive on polymer backplane through printing process, and then cover silver or copper sheet on it to form a conductive circuit. Printing of photovoltaic backplane can improve the conversion efficiency of solar panels, thereby improving the power generation efficiency of the entire solar cell module. The printed backplane is placed in an oven for curing. During the curing process, the conductive adhesive and silver sheet can be fixed, thereby enhancing the stability and durability of the circuit. However, the existing solar panel screen printing and drying equipment generally has the following technical problems:

[0003] Generally, the solar panels need to be dried at a temperature of 60℃ to 120℃ for 1-3 minutes. Since most modern photovoltaic manufacturing industries adopt assembly line production, the assembly line for conveying solar panels is often placed in a heated channel. By drying the solar panels while they are moving, the problem of drying and conveying the solar panels can be solved at the same time. However, the drying device for screen printing of solar panels popular on the market now generally has a heating device fixedly connected to the drying device as a whole. In this way, it may not be possible to flexibly control the parameters of various drying processes in the drying channel for the task of drying screens of solar panels of different models, specifications and thicknesses, resulting in problems such as cracking or shrinkage of the coating screen, which may affect the drying quality of different solar panel products.

[0004] Based on this, a drying device for screen printing of solar panels is proposed. Utility Model Content
