Embodiment 1

[0057] like figure 1 , figure 2 As shown, the cable axial cutting system based on single-point laser triangulation distance measurement includes a control subsystem 1, a moving guide rail 2, a laser transmitter 3, a camera 4, an image analysis module 5, a drive motor 6 and a cable cutting end 7; :

[0058] The moving guide rail 2 is arranged horizontally directly above the cable 8, is electrically connected with the control subsystem 1, and is driven and controlled by the control subsystem 1;

[0059] The laser emitter 3, the camera 4, and the cable cutting end 7 are all arranged on the moving guide rail 2, and the centers of the laser emitter 3, the camera 4, and the cable cutting end 7 are located on the same reference line;

[0060] The laser emitter 3 irradiates the surface of the cable 8 as a laser light source, and forms an image on the camera 4 through a reflection process;

[0061] The output end of the camera 4 is electrically connected to the input end of the ima...

Embodiment 2

[0069] More specifically, such as image 3 As shown, the cable axial cutting method based on single-point laser triangulation ranging includes the following steps:

[0070] S1: Install and initialize the system;

[0071] S2: Adjust the position of the limit plate according to the length of the cable 8 to be cut, control the laser transmitter 3 and the camera 4 to slide directly above the cable 8 by moving the guide rail 2, and collect laser images;

[0072] S3: the image analysis module 5 obtains the imaging plane distance according to the obtained laser image;

[0073] S4: the control subsystem 1 calculates the vertical distance between the surface of the cable 8 and the reference line according to the imaging plane distance, and obtains a preliminary cutting curve;

[0074] S5: Input the cutting thickness value and the height difference between the cable cutting end 7 and the reference line from the control subsystem 1, and generate a cutting curve according to the prelimi...

Embodiment 3

[0099] More specifically, on the basis of Embodiment 1 and Embodiment 2, the cable cutting end 7 and the surface of the cable 8 are set to 5mm, because the cable 8 is not in a straight line when it is installed, and the circle of the protective layer on the outer surface of the cable The degree of consistency is not good, resulting in the commonly used laser distance meter measuring the minimum distance between the tool and the cable surface along the axis, and there is an error between the result set values, with an average distance of 5.15mm. The distance between the cable cutting end 7 and the surface of the cable 8 is measured by a single-point laser triangulation method, and compared with the data measured manually by a laser range finder, the measured data is as follows Figure 5 As shown; the average minimum distance measured by the laser rangefinder is 5.151mm, and the error accuracy is 0.01mm. The average result of manual measurement is 6.206mm, and the error is relati...

According to the cable axial cutting method, different positions of the cable are measured through the laser emitter, the camera and the image analysis module method; a distance between the cable cutting end and the surfaceof the cable is obtained through calculation; a cutting curve is obtained; the cable cutting end is driven to axially cut the cable according to the cutting curve; and therefore, cutting precision andefficiency are high, labor cost is greatly reduced, and the process level of cable cutting is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of cable cutting applications, more specifically, to a cable axial cutting system based on single-point laser triangulation distance measurement, and to a cable axial cutting method based on single-point laser triangulation distance measurement. Background technique [0002] When the cable intermediate joint is made, it is necessary to peel off multiple layers of cable sheath, steel tape armor, copper shielding layer, semi-conductive layer, and cable main insulation layer. The stripped size must be accurate to the millimeter level, or even higher. In order to accurately complete the production of cable intermediate joints. At present, the measurement of on-site cable heads is all manually operated, measuring a section, stripping a section, and installing a part. This kind of work method has cumbersome procedures, high requirements for on-site staff, and it is difficult to achieve high-precision measu...
