Infrared ray welding device for welding bar-shaped zone

Abstract

The invention relates to an infrared ray welding device for welding bar-shaped zone, comprising one or more welding unit mechanisms, wherein the welding unit mechanism comprises a reflecting shade the two ends of which are provided with lampshade fixing end plates; the surface of the inner cavity of the reflecting shade is of a smooth concave mirror, and the inner cavity is a semielliptic columnar cavity body; the two ends of the inner cavity of the reflecting shade are provided with infrared tubes through a tube installation frame; the infrared tube is positioned on one focal line of the semielliptic columnar cavity body, and the other focal line of the semielliptic columnar cavity body is used for arranging the object to be welded; and when more than one welding unit mechanism is arranged, the welding unit mechanisms are connected by a connecting mechanism. The invention is suitable for fast and uniformly welding the object which is fragile and not easy to contact, the device can make infrared ray form a bar-shaped heating zone with consistent temperature, can realize synchronous welding of multiple groups of zones, and has the characteristic that the interval of the welding zone can be adjusted, thus effectively improving the welding quality and welding efficiency, having non-pollution and saving energy.

Description

technical field [0001] The invention relates to a welding device for welding electrical components by using infrared rays, in particular to a welding device for welding solar cells by using infrared heating. Background technique [0002] Today's traditional fuel energy is less and less, and the harm to the environment is also becoming more and more prominent. Renewable energy has become an important topic. People hope that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. Among them, solar energy has become the focus of renewable energy due to its unique advantages of abundant sources, no pollution, low cost and free use. [0003] A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. At present, a total of 136 countries in the world are investing in the popularization and application of solar cells, and 95 of them are conducting ...

Problems solved by technology

However, this device and method can only independently weld a single component, and cannot weld a group of components at the same time; and the infrared rays gathered by the convex lens form a linear light band, and the irradiation range is limited; Although the heating and drying steps can prevent solder joints from being soldered, they also reduce production efficiency to a certain extent
