Technical Field

[0001] This application relates to the technical field of cable detection, and particularly to an on-line cable spacing detection system. Background Art

[0002] In the cable industry, a cable is a relatively common cable structure. Common structural production forms include the form of extruding an outer sheath for the cable and the form of applying a film to the cable. The form of extruding an outer sheath is to arrange multiple single wires side by side and then extrude an outer sheath on the periphery through an extruder. The spacing between multiple single wires in the cable needs to be within the controlled deviation.

[0003] In current cable production, the main way to control the cable spacing is through visual inspection by technicians and the machine adjustment experience of employees. After the start-up debugging and sampling test are qualified, the machine continues to run. When cable quality problems occur during the production process, it is difficult to obtain timely monitoring and repair, resulting in an increase in the product rejection rate. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0013] Embodiment

[0014] To solve the above technical problems, this embodiment provides an on-line detection system for wire arrangement spacing, which is used to detect and rectify the wire arrangement spacing before entering the extruder. As Figure 1As shown in the figure, it includes a guiding component 10, a deviation rectifying component 20, a positioning guide wheel 30, and a detection component 40 that are sequentially arranged along the conveying path of several single wires. The deviation rectifying component 20 is located between the guiding component 10 and the positioning guide wheel 30, and the detection component 40 is located on the side of the positioning guide wheel 30 away from the deviation rectifying component 20. A plurality of positioning grooves 31 are axially distributed on the surface of the positioning guide wheel 30. Each single wire passes through the guiding of the guiding component 10, then passes through the deviation rectifying component 20, and then moves from the deviation rectifying component 20 and passes through the positioning grooves 31 of the positioning guide wheel 30. The detection component 40 is used to detect the spacing of several single wires. It also includes a host controller, which is electrically connected to the detection component 40 and the deviation rectifying component 20. Furthermore, the single wires are preliminarily positioned through the positioning grooves 31, and then the distance between adjacent single wires is detected by the detection component 40 and fed back to the host controller. Then, the host controller issues an instruction to the deviation rectifying component 20, and the distance of each single wire is rectified through the deviation rectifying component 20, so that the spacing of each single wire accurately falls within the controlled deviation, thereby realizing real-time detection and rectification during the production process of wire arranging and improving the quality of wire arranging.

[0015] Specifically, the detection component 40 includes a light source 41 arranged below the moving path of the single wire and an industrial camera 42 located above the moving path of the single wire. The industrial camera 42 is directly above the light source 41, and the industrial camera 42 is electrically connected to the host controller. Several single wires pass through below the industrial camera 42. The industrial camera 42 takes pictures of multiple single wires to obtain images and feeds the images back to the host controller. The host controller performs binary processing on the obtained images. By calculating the gray level gradient of the images, fitting the contour line after filtering, calculating the line width and spacing of the single wires through the edge line, judging whether there is a calibration error by comparing the self-checking spacing with the standard value, thereby calculating the deviation value of the distance between the single wires, and then issuing an instruction to the deviation rectifying component 20 through the industrial camera 42, and making the corresponding single wire be rectified through the deviation rectifying component 20 to ensure that the spacing of each single wire accurately falls within the controlled deviation.

[0016] Furthermore, several groups of guiding components 10 and deviation rectifying components 20 are provided, and each single wire is individually matched with a group of guiding components 10 and deviation rectifying components 20. Due to the presence of multiple deviation rectifying components 20 with different positions for each, through the guiding function of the guiding component 10, the single wire is guided to pass through the corresponding deviation rectifying component 20, and the position of the single wire is rectified by the deviation rectifying component 20. Among them, the guiding component 10 includes several fixedly arranged fixed wheels. A plurality of single wires are led out from a plurality of wire reels, pass through the guiding of the fixed wheels and extend to the deviation rectifying component 20, then the single wires are preliminarily positioned through the positioning grooves 31, and then the distance between adjacent single wires is detected by the detection component 40, and finally they enter the extruder to extrude the outer sheath. In some embodiments, the guiding component 10, the deviation rectifying component 20, and the positioning guide wheel 30 can all be installed on the vertical wallboard through connecting rods.

[0017] Specifically, a number of positioning grooves 31 distributed axially are provided on the surface of the positioning guide wheel 30. Each single wire passes through the positioning grooves 31 of the positioning guide wheel 30 after passing through the guiding assembly 10 and the deviation rectifying assembly 20, and the single wires are preliminarily positioned through the positioning grooves 31. Among them, the width of the positioning groove 31 is greater than the diameter of the single wire. On the one hand, it is to enable the single wire to pass through the positioning groove 31 without friction. On the other hand, it is to leave a gap for the deviation rectifying assembly 20 to make adjustments to ensure that the distance between each single wire accurately falls within the controlled deviation range.

[0018] Furthermore, the deviation rectifying assembly 20 includes a deviation rectifying wheel and a driver connected to the deviation rectifying wheel. A groove for the single wire to pass through is provided on the surface of the deviation rectifying wheel. The driver can be a cylinder, and the telescopic end of the cylinder is connected to the end face of the deviation rectifying wheel. Thus, the deviation rectifying wheel is driven by the driver to move back and forth in a direction perpendicular to the single wire, and the position of a single wire is rectified by one deviation rectifying wheel, so as to accurately adjust the distance between each single wire and ensure the forming quality of the wire arrangement. Among them, the driver is connected to the upper control computer. Thus, after the upper control computer calculates the deviation value based on the information fed back by the detection assembly 40, it can adjust the distance between the single wires by controlling the telescopic stroke of the driver.

[0019] In summary, the solution of the present application sequentially sets a guiding assembly, a deviation rectifying assembly, a positioning guide wheel, and a detection assembly. A number of positioning grooves distributed axially are provided on the surface of the positioning guide wheel. Each single wire passes through the deviation rectifying assembly after being guided by the guiding assembly, and then moves from the deviation rectifying assembly and passes through the positioning grooves of the positioning guide wheel. The detection assembly is used to detect the spacing between several single wires. The upper control computer is electrically connected to the detection assembly and the deviation rectifying assembly. Thus, each single wire is preliminarily positioned through the positioning groove, and then the distance between adjacent single wires is detected by the detection assembly and fed back to the upper control computer. Then, the upper control computer issues an instruction to the deviation rectifying assembly, and the distance of each single wire is rectified by the deviation rectifying assembly, so that the spacing between the single wires accurately falls within the controlled deviation range, thereby detecting and rectifying in real time during the wire arrangement production process and improving the quality of the wire arrangement.

[0020] The above-described embodiments do not constitute a limitation on the protection scope of the technical solution. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the above-described embodiments shall be included within the protection scope of the technical solution.
