Abstract

The invention provides a method and system for positioning a welding point. The method comprises the following steps that 1, the hole position of a workpiece to be positioned is determined according to a first gray image of the workpiece to be positioned; 2, a hole position image is acquired according to the hole position, and the hole position image is generated into a second gray image; and 3, according to the first gray image and the second gray image, the center point coordinates of the hole position is obtained by using a gray model. According to the method and system for positioning the welding point, the center point coordinates of the hole position can be accurately and rapidly obtained, then the speed and accuracy requirements of the whole production line are met, and the exact position is positioned for a next spot welding process.

Description

technical field [0001] The present invention relates to the technical field of image recognition, and more specifically, to a method and system for locating welding points. Background technique [0002] The spot welding process is a metal connection that forms a permanent bond. During welding, the weldment is locally heated by the welding current, and pressure is applied to the contact heating of the weldment to form a solder joint. Spot welding is a high-speed and economical connection method, which is suitable for the manufacture of stamped and rolled thin-plate components that can be overlapped, the joints do not need to be airtight, and the thickness is less than 5mm. The spot welding process is currently widely used in various industrial sectors. It can not only weld low-carbon steel and low-alloy steel, but also weld parts composed of high-carbon steel, high-manganese steel, stainless steel, aluminum alloy, and titanium alloy. [0003] At present, spot welding is mai...
