[0023] Cable is an electrical transmission line composed of multiple conductors insulated and combined together by insulating materials. It uses the movement of electrons in the conductors under the action of electric and magnetic fields to complete the transmission of electricity or signals. As shown in Figure 1, the cable is generally composed of a core 11 and a metal sheath 12. The cable metal sheath 12 is wrapped around the core 11 by an aluminum strip longitudinal argon arc welding process. The metal sheath 12 protects the internal structure of the cable from being affected by the external environment. The production of the metal sheath 12 is completed through processes such as precision cutting, forming, welding, and corrugation. The semi-finished cable obtains a linear speed under the traction of the conveying device. At the same time, the corrugating knife of the corrugating device rotates on the surface of the metal sheath 12 to press out threads. When the linear speed and the rotation speed of the corrugating knife maintain a certain speed ratio, a continuous and uniform spiral pattern can be rolled out.

[0031] The detection component 20 also includes an image processing unit 23. The image processing unit 23 is connected to the visual sensor 22, and the image processing unit 23 can obtain the appearance parameters of the cable based on the appearance image. The visual sensor 22 has high acquisition accuracy and can more accurately reflect the appearance of the cable than manual detection; combined with the image processing unit 23, the appearance image is processed to obtain the appearance parameters, so that the staff can timely control and adjust the appearance parameters of the cable, effectively improving the measurement efficiency of the cable appearance and meeting the needs of automated and efficient production of cables.

[0032] As shown in FIG3 , the image processing unit 23 includes a conversion module 231, a first calculation module 232, and a judgment module 233. The visual sensor 22 is electrically connected to the conversion module 231, and the conversion module 231 is electrically connected to the first calculation module 232.

[0036] Furthermore, the visual sensor 22 of the present application can also collect the position information of the cable, and the first drive unit and the second drive unit are also connected to the visual sensor 22. The first drive unit and the second drive unit can receive the position information of the cable, and drive the detection platform 21 to move based on the position information, so that the detection platform 21 reaches the detection position, which is the position of the detection platform 21 when the wire hole 211 is coaxial with the cable. Move the detection platform 21 to be coaxial with the cable in the wire hole 211, so that the cable will not be blocked / there will be no image acquisition blind spot, which is convenient for the visual sensor 22 on the detection platform 21 to fully and accurately collect the appearance image of the cable.

[0037] Specifically, the cable appearance measuring device further includes a second calculation module 241 and a control module 242. The visual sensor 22 is electrically connected to the second calculation module 241, the second calculation module 241 is electrically connected to the control module 242, and the control module 242 is electrically connected to the adjustment component 30. The visual sensor 22 sends the acquired position information of the cable to the second calculation module 241. The second calculation module 241 calculates the offset of the cable in the second direction and the third direction based on the position information of the cable and the center point position of the wire hole 211, and then outputs the calculation result to the control module 242. Finally, the control module 242 controls the first drive unit and / or the second drive unit to drive the detection platform 21 to move.

[0038] The appearance measurement device also includes a base 41 and a support platform 42.

[0039] Referring to Figure 2 again, the first drive unit includes a moving part 31, a track 32 and a first drive part 33. The moving part 31 is connected to the bottom of the support platform 42 and is slidably connected to the track 32. The track 32 is arranged on the base 41 and extends along the second direction (shown as the left and right direction in Figure 2). The first drive part 33 is electrically connected to the control module 242, and the control module 242 can send a control instruction to the first drive part 33; the first drive part 33 is arranged on the track 32 and is transmission-connected to the moving part 31. The first drive part 33 is used to drive the moving part 31 to move relative to the track 32, so as to drive the support platform 42, the second drive unit and the detection platform 21 to move along the second direction. In the embodiment disclosed in the present application, the moving part 31 and the track 32 can adopt the structure of an electric slide rail and a slider.

[0040] The second drive unit includes a second drive member 34 and a power output member 35. The second drive member 34 is fixed in the support platform 42, and the power output member 35 is connected between the second drive member 34 and the detection platform 21 by transmission. Specifically, the output end of the second drive member 34 is connected to the power output member 35, and the power output member 35 is threadedly connected to the detection platform 21. The detection platform 21 at least partially extends into the support platform 42 along the third direction, so that the support platform 42 can limit the detection platform 21 to prevent the detection platform 21 from rotating with the power output member 35. In actual use, the second drive member 34 can drive the power output member 35 to output rotational motion, so that the power output member 35 drives the detection platform 21 to move along the third direction (shown as the up and down direction in Figure 2). In the embodiment disclosed in the present application, the second drive member 34 and the power output member 35 can adopt the structure of a turbine box, a servo motor and a screw rod.

[0041] The appearance measuring device further includes a support member 43, which is connected to the bottom of the test platform 21 and is used to support the test platform 21. The support platform 42 is provided with a first sliding opening, and the support member 43 can slide in the first sliding opening. The support member 43 is sleeved on the power output member 35, and a receiving groove is provided inside the support member 43, and the receiving groove is used for the power output member 35 to extend. Exemplarily, when the power output member 35 rotates forward, the test platform 21 and the support member 43 move downward in the second direction in the first sliding opening, and the power output member 35 extends in the receiving groove; when the power output member 35 rotates reversely, the test platform 21 and the support member 43 move in the second direction in the first sliding opening, and the power output member 35 shortens in the receiving groove.

The meter-counting component 45 can adopt a rotary encoder, and the meter-counting component 45 is connected to the visual sensor 22 and configured to be connected to the cable. The meter-counting component 45 is used to measure the current conveying length of the cable and feed back to the visual sensor 22 (when the cable starts to be conveyed or the corrugating device starts to rotate, the meter-counting component starts to count the meters at the same time), so that the corrugating device and the cable appearance measuring device operate synchronously. Exemplarily, when the current conveying device pulls the cable to move n meters, the corrugating device rolls out a corresponding grain length of n meters on the metal sheath 12. This process can be called the current production of n meters of cable. At the same time, the meter-counting component 45 feeds back the currently recorded signal of producing n meters to the visual sensor 22, and the visual sensor 22 performs appearance measurement on the currently produced n meters of cable, realizing the synchronization of production and measurement, which is conducive to improving the production efficiency of the production line.

[0044] The cable appearance measuring device further comprises a synchronous triggering member 46 . The synchronous triggering member 46 is connected between the metering member 45 and the visual sensor 22 , and is also connected between the control module 242 and the adjusting assembly 30 .

[0045] The working process of the cable production line of the present application is as follows: when the production line is started, the support platform 42, the second driving unit and the detection platform 21 of the cable appearance measuring device move along the second direction to the position of the measured cable under the action of the second driving unit and then stop; the cable is moved along the first direction through the output device and passes through the wire hole 211; the visual sensor 22 obtains the position information of the cable and starts calculation through the second calculation module 241, the control module 242 sends the control instruction to the synchronization trigger 46, and after the synchronization trigger 46 receives the control instruction, it sends the synchronization signal generated by it to the adjustment component 30, The adjusting component 30 adjusts the detection table 21 to the detection position; the metering piece 45 automatically descends until its roller rests on the metal sheath 12 and rotates, and at the same time, the metering piece 45 sends the production signal (signal to start corrugating) to the synchronization trigger 46; after receiving the production signal of the metering piece 45, the synchronization trigger 46 sends the synchronization signal it generates to the visual sensor 22, so that the visual sensor 22 starts to measure the appearance of the produced cables; when the production line stops, all devices stop working, the metering piece 45 is lifted and moved outside the production line to wait, and enters the production line again when the production line moves next time.

[0046] The cable production line of the present application can also be used in conjunction with the order management system 50 and the process design management system 60, and the cable production line is interconnected with the order management system 50 and the process design management system 60. Exemplarily, the order information of the cables to be produced is stored in the order management system 50, the process parameters of the cables identical to the order information are called in the process design management system 60, and the cables are produced on the production line according to the process parameters; it can be understood that the standard parameters compared with the measured appearance parameters in the judgment module 233 are called from the process design management system 60, and the output judgment result can be uploaded to the order management system 50, through which the appearance quality of the cables can be viewed in real time.

[0047] In some embodiments, for cables that fail to meet the standards after the measured appearance parameters are compared with the process parameters, the control device can be activated for automatic adjustment, wherein the outer diameter is adjusted in real time by controlling the width of the precision-cut tape and the size of the sizing die; the groove depth is adjusted by controlling the depth of the corrugating knife; and the pitch is adjusted by adjusting the rotation speed of the corrugating knife.
