Description

AI Robot-Based Precision Deburring Device for Die Casting Parts The present invention relates to an AI robot-based precision deburring device for die-casting parts, and more specifically, to an AI robot-based precision deburring device for die-casting parts that effectively removes burrs from die-casting parts through vision inspection. Robots are also being used to improve the efficiency of automated manufacturing in processes that perform deburring on processed objects, such as machined die-cast parts. At this time, post-processing target areas such as burrs may be formed on the workpiece, and when performing deburring on such post-processing target areas, a path is created along the location of each deburring target area, and deburring on the deburring target area can be performed as the deburring tool moves along the path. However, even if a process to remove burrs from die-cast parts is performed, it is not verified whether they have been completely removed; consequently, the die-cast parts may be transferred to the downstream process while still containing unremoved burrs. In such cases, there is a problem where defects may occur in the downstream process due to the unremoved burrs.
