The 2D gluing detection system is a detection system that realizes signal interaction between vision and robot (PLC), completes image acquisition and processing of the gluing effect, analyzes quality factors such as gluing width, area, position and continuity, displays detection results, and gives alarm reminders for defective products, so as to realize comprehensive monitoring of gluing quality. According to the requirements, the system can be divided into fixed type and follower type. The system is able to detect gluing in different colors and different shapes, with a wide range of applications.
