Liquid crystal display glass positioning, picking method and system, and vision processing system

Abstract

The application discloses a method and system for positioning and picking up liquid crystal display glass and a visual processing system. A robot is used to grab the liquid crystal display glass; a corresponding imaging system is designed according to the characteristics of the liquid crystal display glass and the tray; according to the characteristics of the liquid crystal display glass According to the actual imaging characteristics, a method for positioning the LCD glass image is proposed. First, the template matching method is used to obtain the initial positioning result of the LCD glass in the image, and then the edge points on each edge of the LCD glass are detected. Finally, according to each edge Calculate the position and angle of the LCD glass on the edge points. The liquid crystal display glass can be placed arbitrarily in the material tray, and the position and angle of the liquid crystal display glass can be quickly and accurately positioned, and then the vision processing system cooperates with the robot controller to convert the position and angle information of the precise positioning liquid crystal display glass The axis position picked up by the robot enables the robot to pick up the product quickly, accurately and stably.

Description

technical field [0001] The invention relates to the field of robot vision, in particular to a liquid crystal display glass positioning and picking method and system and a vision processing system. Background technique [0002] In recent years, liquid crystal displays have been widely used in consumer electronics, automotive electronics and other products with display interaction functions. Consumer electronic products such as mobile phones, watches, tablet computers, etc., automotive electronic products such as car dashboards, central control screens, Recorders, navigators, etc., are used to display information such as images, videos, and interactive operation interfaces. The main component of the liquid crystal display is liquid crystal display glass. After cutting a large plate of liquid crystal display glass into a single small piece of liquid crystal display glass, it also needs grinding, cleaning, polarizer bonding, COG, FOG, testing, etc. The production link can be pr...

Problems solved by technology

[0005] The embodiment of the present application discloses a liquid crystal display glass positioning, picking method and system, and a visual processing system to solve the problem in the prior art that the positioning of the liquid crystal display glass cannot be obtained by only using a template matching positioning method during visual processing. The precise position and angle will eventually lead to the problem that the robot may grasp the reverse, grasp the deviation or miss the product
