Optical curing automatic production line of UV curing conductive silver paste

Abstract

The invention relates to an optical curing automatic production line of an UV curing conductive silver paste. The optical curing automatic production line comprises a machine base, wherein a conveying belt is arranged on the machine base, a cover body is fixedly arranged on the machine base along the conveying direction of the conveying belt, the cover body is successively provided with at least one IR lamp tube module and a plurality of UV lamp tube modules along the conveying direction of the conveying belt, an IR lamp tube is installed inside the IR lamp tube module, and UV lamp tubes are installed inside the UV lamp tube modules. The optical curing automatic production line has the beneficial effects of improving the production efficiency (shortening the processing time), improving product yield rate, improving environmental protection, energy conservation and consumption reduction (through comparing electricity consumption for producing the same amount of products), reducing production processes, decreasing investment of production and operation costs, improving production safety, and being capable of being linked to automated production.

Description

technical field [0001] The present invention is to solve the curing process manufacturing of the novel "UV curable conductive silver paste", and proposes a novel UV curable conductive silver paste photochemical curing machine. Background technique [0002] At present, the conductive silver paste used in the mobile phone TP (Touch panel: touch screen) industry is a baked silver paste. After the ITO (Indium Tin Oxide) film printed circuit diagram is completed, it is placed on the "silk screen multi-layer frame" and then baked in an electric oven. The baking temperature is 130°C, and the constant temperature time is 50 minutes. The solvent inside the baking-type silver paste is dried, so that the adsorption force and electrical resistance of the silver paste meet the process requirements. The electric oven technology used must strictly meet the following requirements: at least Class 1000 cleanliness, temperature control accuracy ± 2°C, fast heating, and small air volume (to pre...

AI Technical Summary

Problems solved by technology

[0003] The baked silver paste is dried and solidified in an oven. (1) The most important reason is that the existence efficiency is low (100 ITO films / box, the baking time includes liters, constant, and the temperature is lowered for about 50 minutes); (2) Compared with the present invention, the same amount (3) The yield rate of the product is low after baking (caused by air pollution inside the oven, the wind blows off the ITO film, etc.); (4) The site uses a large area; (6) Supporting special tools are required (silk-screen laminated racks)
