Background

After the surface treatment, the automobile element needs to enter a heat treatment stage, the heat treatment stage usually has special environments such as high temperature, and in the existing heat treatment process, a mullite roller way is generally adopted for transmission, but because the automobile element subjected to the surface treatment is easily damaged at high temperature, such as a sprayed shell, the automobile element is easily wrinkled, peeled and oxidized during high-temperature transmission, and even can react with the transmission roller way, so that the denaturation of the automobile element is caused.

Meanwhile, after the automobile element subjected to heat treatment is transmitted to the tail end of the roller way, the automobile element is usually grabbed and taken away by a robot, but the existing mullite roller way has the problems of high brittleness, high possibility of breakage, high deformation and the like, and the position of the automobile element is influenced by the deformation of the transmission roller and is changed in the process of transmitting the automobile element to the tail end of the roller way from the front end of the roller way, so that the robot cannot accurately grab the automobile element or even cannot grab the automobile element, the waste of the automobile element is caused, and the production efficiency is reduced.

In addition, the roughness of the roller bed surface of the existing conveying roller is difficult to control, if the roughness is too large, the element surface is easily scratched, and if the roughness is too small, the conveying efficiency is obviously reduced.
