Abstract

The invention belongs to the field of automobile gluing and detection and discloses a robot-based gluing quality on-line visual detection device and method. The device comprises a camera, a light source, a computer, a glue gun, a robot and a light source controller. The method comprises dividing a gluing locus into several sections through robot program, outputting glue section numbers to the computer through the robot program, selecting camera and light source parameters, light source controller and computing coefficients and a glue bond diameter limit through the computer according to the glue section numbers, taking a picture through the camera, storing the image, and calculating a glue band diameter according to a glue band diameter-direction pixel pitch extracted from the image and the computing coefficients, storing the glue band diameter through the computer, comparing the stored glue band diameter and the selected glue bond diameter limit and displaying an alarm if the stored glue band diameter is greater than the glue bond diameter limit. The device has a simple structure. The device and method are economic and practical, realize accurate detection and solve the problem that the existing detection device cannot control multiple visual detection units.

Description

technical field [0001] The invention belongs to the field of automobile gluing and detection, and in particular relates to a detection device and method for robot gluing quality. Background technique [0002] With the application of robot gluing in the automatic production line of automobiles, in order to ensure the quality of gluing, a quantitative gluing device is used for gluing to control the amount of glue output. However, if the nozzle of the glue gun is skewed, the glue from the glue gun will not be applied to the workpiece. On the contrary, it will cause glue quality accidents, directly affect the quality of the car, and there may be water leakage and noise in the car. [0003] In the automatic production line of robot body-in-white manufacturing, some gluing areas are not manually guarded, and the traditional manual visual inspection method cannot be carried out. [0004] Publication No. CN204718963U, the patent titled "A Y-△ Type Glue Quality On-line Visual Inspec...
