Description

Pipe glue filling fixing method Technical Field The invention relates to a glue filling process, in particular to a pipe glue filling fixing method. Background The glue filling process is a very important manufacturing process, and the glue filling quality directly influences the appearance quality of the product and further influences the electrical property and the mechanical property of the product. The assembly is very critical in terms of the amount of gum filling from a series of gum filling problems that have been exposed in recent years. At present, when the pipe glue filling operation is carried out, the pipe workpiece is bent to cause certain distortion, the plane degree value is increased, the glue and the pipe workpiece are higher than the surface of the product in the glue filling process, and the quality of the product is affected. Disclosure of Invention In order to overcome the defects, the invention provides a pipe glue pouring fixing method, which reduces the flatness requirement of the pipe after being bent, thereby reducing the bending difficulty of pipe workpieces, ensuring that the glue and the pipe workpieces are not higher than the product surface in the glue pouring process, and ensuring the quality of the product.
