specific Embodiment 1

[0013] Specific embodiment 1: The cable appearance inspection equipment of this embodiment includes a host computer, an image acquisition unit, a pay-off reel, a take-up reel, a background panel, a special light source, a first auxiliary wire reel, and a second auxiliary wire reel. Before the equipment starts working, it is necessary to fix the two ends of the cable on the pay-off reel and take-up reel. When working, keep the pay-off reel and take-up reel at the same line speed, and the cable is in tension when passing through the detection area. Straight state. A background panel is set in the appearance detection area. When the cable passes through the background panel, the image acquisition unit acquires the image of the cable and uploads the image to the host computer. The host computer analyzes and processes the image. When the detection is determined to be a defective product, a stop signal is issued. , so that the pay-off reel and take-up reel stop rotating, and an alar...

specific Embodiment 2

[0023] Specific embodiment two: the main design idea of ​​this embodiment is: use special light source to irradiate the upper and lower sides of the cable, so that there is no shadow area in the whole cable, the camera collects the images of the upper and lower sides of the cable to be tested, and the host computer compares the collected images After processing, judge whether there are burrs, cracks, spots, etc., and display the defect image on the LED display screen, and send an alarm signal to the staff.

[0024] The cable appearance inspection equipment of this embodiment includes a host computer, an image acquisition unit, a pay-off reel, a take-up reel, a background panel, a special light source, a first auxiliary wire reel, and a second auxiliary wire reel. Before the appearance inspection equipment starts to work, It is necessary to fix the two ends of the cable on the pay-off reel and take-up reel first. When working, keep the pay-off reel and take-up reel at the same l...

Abstract

The invention discloses finished cable appearance inspection equipment which comprises an upper computer, an image acquisition unit, a pay-off wheel, a take-up wheel, a first auxiliary wire wheel and a second auxiliary wire wheel, wherein a cable is led out of the pay-off wheel, and is wound around the first auxiliary wire wheel and the second auxiliary wire wheel and then wound on the take-up wheel, so that the same section of the cable passes through an image acquisition area for three times; when the cable passes through an acquisition area of the image acquisition unit, the image acquisition unit acquires a cable image, and the image is analyzed and processed by the upper computer; when the upper computer determines that the cable is defective, a stop signal is transmitted, and the take-up wheel and the pay-off wheel stop working. With the adoption of a manner of identifying cable appearance defects by a machine, the problems of low labor efficiency and high error rate are solved.

Description

technical field [0001] The invention belongs to the technical field of cable appearance inspection, relates to image processing technology, and in particular to a finished cable appearance inspection device. Background technique [0002] The appearance inspection of finished cables is an important part of the cable production process. At present, the appearance inspection of finished cables is carried out manually. During the inspection process, the two ends of the cable are pay-off and take-up reels, pay-off and take-up reels Keep the same line speed, keep the cable in a tight state, and rely on manual inspection of the appearance of the cable. This manual inspection method is prone to visual fatigue, and cannot inspect the other side that cannot be seen by sight. As the requirements for surface quality of cable products become more and more stringent, the appearance of finished cables has defects such as burrs, cracks, and spots. , has become a key to the cable quality pr...
