Method for Improving the Smoothness of Weld Seam of Metal Thermos Cup and Its Automatic Welding Equipment

Abstract

The invention discloses a method for improving the smoothness of a weld joint of a metal vacuum cup and an automatic welding equipment for the method. The method comprises the steps that the weld joint data are collected; the weld joint data are screened; local polynomial fitting is carried out; and welding is controlled. The automatic welding equipment using the method comprises a data measuring device, an automatic welding equipment body and a four-power independent conveying one-way circulation device, wherein the four-power independent conveying one-way circulation device is used for conveying and positioning the metal vacuum cup to be welded; the automatic welding equipment body is a laser welding device; the four-power independent conveying one-way circulation device comprises a base 200 and conveying guide rails 201; one-way driving mechanisms are arranged under the conveying guide rails; and shunting mechanisms of sliding bases arranged at the joint parts of the adjacent conveying guide rails 201. According to the equipment and the method, the welding quality of a port of the metal vacuum cup can be improved, the welding speed of the port of the metal vacuum cup can be increased, the labor intensity can be reduced, and a wide application market and huge economic benefits can be achieved.

Description

technical field [0001] The invention relates to a method for improving the smoothness of the welding seam of a metal thermos cup, and automatic welding equipment using the method. Background technique [0002] Metal thermos cups (such as stainless steel thermos cups, titanium thermos cups, etc.) are thin-walled cylinders. After the inner tank and the outer shell are respectively rolled and formed by water expansion, the two need to be welded together at the port. The gap at the port between the inner bag and the shell is called the gap to be welded (also called the weld seam). [0003] At present, the welding of the welded seam of the metal thermos cup port is still at the level of manual operation. The processor rotates the metal thermos cup to be welded by hand, so that the port weld seam rotates under the welding torch of the laser welding equipment or argon arc welding equipment. The torch does not move and the weld seam moves to complete the welding of the weld seam. ...

Problems solved by technology

Manual welding of the thermos cup port, the welding quality varies from person to person, it is not easy to control, and the labor intensity is high and the efficiency is low

People try to use welding robots to weld the weld seam of the metal thermos cup port, but because the weld seam is an irregular curve in space, the smoothness of the weld seam is not ideal enough, and even jagged
