Problems solved by technology

[0002] The existing quality inspection of cable strands is through manual detection and visual inspection with a micrometer. This kind of contact manual inspection needs to stop the transmission of cable strands for detection and manual marking. Manual marking has low efficiency, large errors, and inaccurate marking. Accurate problems, and even damage the cable strands and scratch the palm of your hand

[0022] Preferably, the above-mentioned image processing and recognition module adopts a control computer PC.

[0023] Preferably, the above-mentioned image acquisition module includes an industrial camera 1 and an image acquisitio...

Embodiment 3

[0027] Embodiment 3: a detection method of a cable strand quality detection system, the method comprises the following steps:

[0028] (1) After the control computer is started and the system is running, the three industrial cameras in the image acquisition module collect the cable strand image online, and after each industrial camera collects a frame of image, it is immediately transmitted to the corresponding image acquisition card;

[0029] (2) The image acquisition card immediately transmits the received high-quality cable strand image to the image processing and identification module, that is, the control computer PC;

[0030] (3) Before identification, it is necessary to calibrate the industrial camera, that is, to correct the radial distortion of the camera. The qualified cable strands are collected through the image acquisition system, and the control computer PC processes the images of the qualified cable strands to obtain the radial distortion. Distortion correction ...

Abstract

The invention discloses a marking and positioning apparatus for quality detection of twisted cables. The apparatus includes a drawing pen, which is connected to a telescopic rod. The tail end of the telescopic rod is connected vertically to a swinging shaft. The swinging shaft is connected to a swing motor mounted on a sliding base. The sliding base is connected to a fixed bench through a slide piece and guide rail pair. A driving mechanism, which drives the sliding base to move in the direction of the twisted cable, is connected to the sliding base. The telescopic drawing pen can move and swing during marking operation, so that a defect can be marked, thereby completing quick marking on the surface of the twisted cable. The apparatus has simple structure. Due to the elastically telescopicdrawing pen, marking range is wide and the marked symbol is more obvious. The apparatus also can avoid damage, due to hard collision, of the drawing pen. By means of the swinging shaft, the slide piece and guide rail pair and the driving mechanism, the drawing pen can swing quickly and move quickly along the cable. The marking and positioning apparatus has simple structure and low cost.

Description

technical field [0001] The invention belongs to the technical field of cable strand quality detection, and in particular relates to a marking positioning device for cable strand quality detection. Background technique [0002] The existing quality inspection of cable strands is through manual detection and visual inspection with a micrometer. This kind of contact manual inspection needs to stop the transmission of cable strands for detection and manual marking. Manual marking has low efficiency, large errors, and inaccurate marking. Accuracy issues, and even damage to cable strands and scratches on the palm of your hand. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a marking positioning device for cable strand quality detection, which can realize online marking, greatly improve marking efficiency, greatly reduce errors, make marking more accurate, and avoid affecting production progress and damaging cable stra...
