Control method applied to automatic cleaning device of welding torch of industrial arc welding robot

Abstract

The invention discloses a control method applied to a full-automatic cleaning device for a welding gun of an industrial arc welding robot. When cleaning is needed, a control system instructs a gun head of the welding robot to move to the position above a guider, the guider is pressed downwards and moves down, a travel switch contact leaves a slider, a travel switch is switched on, a motor drives ascraper to clean residues on the inner wall of the welding gun head, the residues are discharged automatically into a waste box through the scraper, the welding gun returns to work after being cleaned, the guider returns to the initial position under the stress action of a spring, the travel switch contact is propped against the slider again, the travel switch is switched off, the motor stops running, and the cleaning process is finished; the robot returns to a welding working position, the control system stops and resets automatically and waits for next cleaning action instruction of the robot, and cleaning is performed regularly. Manual cleaning of splashing welding residues on the inner wall of the welding gun can be replaced, efficiency is increased, and manual labor intensity is reduced.

Description

Technical field [0001] The invention relates to a control method applied to an automatic cleaning device of an industrial arc welding robot welding gun. Background technique [0002] With the mass production of modern industrial robots, a large number of problems have also been discovered. After the robot welding is completed, a large amount of residue will be generated on the inner wall of the welding torch head, which affects the appearance and quality of the welding process, and causes certain damage to the torch head. It needs to be disassembled and cleaned at regular intervals. [0003] Industrial arc welding industrial robots replace manual operations and continuously work in an environment with a relatively high temporary load rate. Due to the working conditions of gas shielded welding, it is impossible to achieve no splashes and particles formed during short-circuit transfer welding. Will gather on the protective sleeve of the gun head and the conductive tip. If the weldin...

Problems solved by technology

When the robot is finished welding, a large amount of residue will be generated on the inner wall of the welding torch head, which will affect the appearance and quality of the welding process, and cause certain damage to the torch head, which needs to be disassembled and cleaned at regular intervals

[0003] Industrial arc welding industrial robots replace manual work and work continuously in an environment with a relatively high duty cycle. Due to the working conditions of gas shielded welding, it is impossible to completely avoid spatter during the short-circuit transition welding process, and the particles formed by spatter If the welding time is too long, the spatter will accumulate too much, and it is easy to form a clogged cavity, resulting in poor flow of protective gas, which cannot protect the weld seam, thus forming welding defects , if the robot stops at this time, there will be safety hazards if the welding spatter in the sleeve is manually cleaned, and it is easy to lose the efficient welding effect of robot automation
