Welding fume collecting device and method capable of automatically tracking and positioning welding point

Abstract

The invention discloses a welding fume collecting device and a welding fume collecting method capable of automatically tracking and positioning a welding point. The welding fume collecting device comprises a tracking control system and a welding fume exhaust tube, wherein the tracking control system comprises an image sensor, an intelligent control unit, a mechanical transmission unit and a mechanical arm; the image sensor is connected with the intelligent control unit; the intelligent control unit is connected with the mechanical transmission unit; the mechanical transmission unit is connected with the mechanical arm; and the image sensor is arranged at the end part of the mechanical arm. The welding fume collecting method comprises the following steps of: sensing visible light or infrared rays emitted by the welding point by using the image sensor, wherein the welding point is a light spot in a sensed image; transmitting image information to the intelligent control unit through the image sensor, analyzing and processing the image information through the intelligent control unit, calculating the change direction and distance of a light spot coordinate, and controlling the mechanical transmission unit to drive the mechanical arm to move; and when the light spot coordinate value is the same as the preset point coordinate value, stopping the movement of the mechanical arm. The device and the method have high working efficiency and low energy consumption, and can automatically realize the tracking of the welding point.

Description

technical field [0001] The invention relates to a welding fume collecting device, in particular to a welding fume collecting device and method capable of automatically tracking and positioning welding points. Background technique [0002] With the progress of society, people's requirements for environmental protection are getting higher and higher. In the process of mechanical equipment manufacturing, it is often necessary to weld workpieces. During the welding process, a large amount of harmful fumes will be generated, which need to be collected and disposed of in time. [0003] At present, there are two main methods for collecting welding fumes: one is to collect and process the fumes in the welding operation area of ​​the workpiece as a whole. Although this method is simple to operate, the exhaust area is large, so the exhaust volume is large. The energy consumption is high, and the smoke removal effect is not ideal; the other is to use the point-to-point method, that is...

AI Technical Summary

Problems solved by technology

At present, there are welding fume collection devices on the market that can move synchronously with the welding spot. Most of them can only move in a straight line, and the speed of the movement is a preset fixed value, which has great limitations: when When the welding speed is changing or the welding speed is not consistent with the preset speed of this synchronization device, the welding point and the welding fume exhaust port will not be synchronized. At this time, the purpose of efficiently collecting welding fume is often not achieved
