KR-102965101-B1 - Welding slag removal automation Apparatus

Abstract

The present invention relates to an automated welding slag removal device. The automated welding slag removal device comprises: an object fixing unit that rotates a jig for gripping an object that has been welded and has a bead formed; a slag removal unit including a brush that rotates in the same direction as the jig corresponding to the bead of the object and contacts the direction in which the jig rises to remove slag formed on the surface of the bead; and a first conveying unit that slides the fixing unit toward the slag removal unit so that the bead comes into contact with the brush. By detaching the slag through friction between the brush and the slag on the bead while the object is rotated at a low speed, the device enables rapid and precise removal of slag, thereby improving the efficiency and precision of slag removal. Furthermore, during the conveying and return of the main body for slag detachment, the device comes into close contact with the jig to prevent over-entry of the main body, and in the event of non-operation of the device, stud pins contact both sides of the jig to prevent rotation of the jig, thereby providing safety and convenience when attaching the object to the jig. It has the effect of improving durability by preventing the scattering of detached sludge (slag) and protecting the motor.

Description

Welding slag removal automation apparatus The following examples relate to an automated welding slag removal device. Conventionally, to remove slag formed on the bead surface after the welding process, manual methods were attempted in which an operator used striking tools such as a hammer, or automation was attempted by replacing the end effector of a welding robot with a slag remover. However, in the case of automated devices, the method of crushing slag by applying pressure to the bead surface using an impactor, such as an air-driven chisel (pneumatic multicore chisel), causes extreme vibrations that are transmitted to the robot body, increasing mechanical fatigue and inducing failures, and there were limitations, particularly in their application to small robots. In addition, manual operation resulted in significant quality variations depending on the operator's skill level, and not only was it difficult to completely remove slag from concave corners such as ship T-bars, but fine dust generated during the removal process also contaminated the working environment and caused equipment malfunctions. In addition, existing devices had structural defects in which they could not respond in real-time to irregular shape changes of the beads, resulting in excessive contact force or the formation of cleaning blind spots, and there was a problem where removed slag fragments scattered in all directions, hindering process continuity.
