Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing, and in particular to an automated visual inspection center for projection welding of automotive forgings. Background Technology
[0002] Welding is a common process in industrial production. It involves joining metal parts using various fusible alloys (solder). Solder has a lower melting point than the materials being welded, allowing the parts to bond through molecular connections on their surfaces without melting. In today's manufacturing industries, a large portion of seamless metal connections are achieved through welding. Welding is typically done manually, requiring a high level of operator skill. After welding, defects such as porosity and undercut are common, necessitating repair. Robots, on the other hand, are mechanical devices that can be controlled by humans, run pre-programmed procedures, or act according to principles established using artificial intelligence. Their task is to assist or replace human workers. With increasing numbers of robots appearing in manufacturing, the welding industry also needs such robots.
[0003] Existing automated vision inspection systems for automotive forging projection welding machining centers are used to weld the left and right hinge reinforcement plates of the hood, the left fender bracket assembly, and the right fender bracket assembly.
[0004] The welding process for nuts on various products, including the upper hinge reinforcement plate assembly of the left front door, the upper hinge reinforcement plate assembly of the right front door, the lower hinge reinforcement plate assembly of the left front door, the lower hinge reinforcement plate assembly of the right front door, the lower hinge reinforcement plate assembly of the left rear door, and the lower hinge reinforcement plate assembly of the right rear door, suffers from drawbacks such as low product quality, low welding quality pass rate, difficulty in balanced production and refined operation, low product quality, and significant safety and adjustment challenges.
