Description

TECHNICAL FIELD

[0001] The utility model relates to cable detection related technical field, especially an AOI machine vision appearance detection device. BACKGROUND

[0002] With the development of science and technology, machines gradually replace manual work and become the mainstream of industrial development, and in the mass production process of products in manufacturing industry, appearance defects inevitably occur in part of the products, so the product appearance needs to be detected. Wire products are no exception, and because wire products are usually thin and long, the appearance defect detection is more difficult in the production and processing process. Wire products also have size requirements and line sequence identification requirements. When the number of cores reaches 4 or more, manual identification and detection can easily lead to various differences, and the proportion of defects is 5%-8%. Manual detection is inefficient, and 3-4 people are needed to cooperate with the automatic production line to meet the production capacity.

[0003] Currently, there are devices on the market that can monitor cable appearance defects, such as the Chinese utility model patent application with patent announcement number CN206348285U, which discloses a cable appearance defect real-time monitoring assembly, which comprises a front positioning assembly, an appearance detector and a rear positioning assembly. The appearance detector is placed between the front positioning assembly and the rear positioning assembly, and the front positioning assembly and the rear positioning assembly are symmetrically distributed around the appearance detector. The appearance detector includes a box body and a detection mechanism, the detection mechanism is installed inside the box body, the detection mechanism includes a mounting disc, a fixing mechanism and a plurality of industrial cameras, the fixing mechanism is installed on the mounting disc, and the industrial cameras are installed on the fixing mechanism. The industrial camera is also provided with a distance sensor. It can dynamically fix the focal length to obtain clear images; it is suitable for cables of different diameters and does not require manual adjustment; it saves equipment floor space while ensuring a large turning radius of the cable (less damage to the cable), especially for monitoring large-diameter cables.

[0005] In this technical solution, the focal length is dynamically fixed to obtain clear images, which is more suitable for detecting large-diameter cables, and the detection mechanism in the box can only detect one cable at a time. For multiple cores that need to be detected at the same time and have small diameters, it cannot be monitored. In addition, the technical solution does not provide a line sequence detector, and does not have a line sequence detection function. For products that need to be detected for line sequence, it cannot be effectively detected, and has great limitations in use.
