Embodiment

[0063] Embodiment: use this detection method to realize the detection of the side glue dispensing quality of the injection molding frame, and complete the quality evaluation. The available inspection images (grayscale) taken by the camera are as Image 6 ; Perform Gaussian filtering on the basis of the grayscale image and set the threshold to binarize the image as Figure 7 ; And traverse the pixels according to the idea to know the maximum width and average width of the features in the image, such as Figure 8 . In addition, find the minimum circumscribed rectangle of the feature to find its fitting straight line and calculate the error value of the previous width measurement, and feed back all the above-mentioned measured results to the window interface such as Figure 9 .

Abstract

The invention discloses an adhesive dispensing quality visual detection method based on a robot intelligent tail end, and the method employs a kinematics transfer matrix operation method to position the robot visual tail end at a vertical position, and carries out the visual collection. The acquired image is subjected to the steps of pre-processing, feature extraction, parameter calculation and the like, and then the calculated parameters are transmitted to a control unit at the tail end of the robot carrying the camera, so that the posture of the camera is adjusted within a rotation degree offreedom to obtain an original image with a smaller error. The system finally realizes width detection considering the influence of the shooting angle and not considering the influence of the shootingangle, and gives out the width value with the pixel as the unit.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of dispensing tape detection of injection molded parts, and relates to a visual detection method for dispensing quality based on a robot intelligent terminal. [0003] 【Background technique】 [0004] The dispensing process is widely used in various structural parts packaging, connection and other working conditions. After the dispensing process is completed, the dispensing quality needs to be tested. Since the material is non-metal, the mechanical properties such as hardness and strength are much different from those of metals. A considerable part of the methods suitable for quality inspection after metal processing are not suitable for dispensing. Traditional dispensing quality inspection still relies heavily on manual inspection, resulting in high cost, low efficiency and poor accuracy in the quality inspection process. [0005] Machine vision is the next hot branch topic in the field of artific...
