[0040] Referring to Figure 1 and Figure 2 , this application provides an aluminum-clad steel wire detection device 100 for detecting a composite metal wire 200. The aluminum-clad steel wire detection device 100 includes a plurality of ultrasonic probes 110, an ultrasonic detection device 130, and a control device 120. The plurality of ultrasonic probes 110 are disposed around a first axis in a first plane, the first axis being the axis formed by the conveying direction of the composite metal wire 200, and the first plane being perpendicular to the first axis; the ultrasonic probes 110 are used to emit detection pulses and receive reflected pulses of the detection pulses. The ultrasonic detection device 130 is provided with a first accommodation cavity 131, and the plurality of ultrasonic probes 110 are disposed in the first accommodation cavity 131; a coupling liquid for transmitting the detection pulses and the reflected pulses is provided in the first accommodation cavity 131. The control device 120 is electrically connected to the plurality of ultrasonic probes 110 respectively; the control device 120 is used to control the ultrasonic probes 110 to emit detection pulses, detect the time duration between the emission of the detection pulses and the reception of the reflected pulses, and obtain the thickness parameter of the composite metal wire 200 according to the time duration.

[0041] In this embodiment, the aluminum-clad steel wire detection device 100 can be applied to the detection of various composite metal wires 200, for example, aluminum-clad steel wires, copper-clad steel wires, zinc-clad steel wires, etc. During the production process of the composite metal wire 200, there may be a deviation in the thickness between the inner metal core wire and the outer cladding layer, resulting in the problem of eccentricity of the metal core wire.

[0042] By arranging multiple ultrasonic probes 110 around the conveying direction of the composite metal wire 200, the produced composite metal wire 200 can be detected in real time. The control device 120 controls the ultrasonic probes 110 to emit detection pulses. According to the ultrasonic pulse reflection principle, the detection pulses will be reflected back to the ultrasonic probes 110 on the surface of the measured composite metal wire 200. By calculating the duration from the emission to the return of the detection pulses, the thickness parameter of the outer metal layer of the composite metal wire 200 can be determined, thereby determining the eccentricity of the composite metal wire 200 to adjust the wire production settings in a timely manner. By arranging multiple ultrasonic probes 110, the thickness of the outer metal layer of the composite metal wire 200 at multiple points on the first plane can be detected, so that the eccentricity of the composite metal wire 200 can be determined more accurately.

[0043] Among them, the control device 120 can be implemented by using a chip with control functions such as a microprocessor, FPGA (Field Programmable Gate Array), etc., or can also be the control device in the production system 10. The multiple ultrasonic probes 110 can be fixed around the first axis through a bracket. The included angle between the multiple ultrasonic probes 110 can be set to be the same or can be set differently according to actual applications.

[0044] In an embodiment, the aluminum-clad steel wire detection device 100 further includes an ultrasonic detection device 130. The ultrasonic detection device 130 also has a first inlet and a first outlet, and the first inlet and the first outlet are arranged on the first axis and communicate with the first accommodating cavity 131.

[0045] In this embodiment, the composite metal wire 200 can enter from the first inlet and exit from the first outlet. By arranging a coupling liquid in the first accommodating cavity 131, the loss of the detection pulses during transmission can be reduced, and the accuracy of the detection results can be improved. Among them, the coupling liquid can be selected from water or an ultrasonic coupling agent. The first accommodating cavity 131 can be set as a closed cavity and filled with the coupling liquid.

[0046] In this application, by arranging multiple ultrasonic probes 110 in the conveying direction of the composite metal wire 200, the thickness of the composite metal wire 200 during the production process can be detected in real time. The control device 120 calculates the eccentricity based on the thickness of the composite metal wire 200, thereby monitoring the production situation in real time. If there is an abnormality, the problem can be discovered and adjusted in a timely manner, improving the production efficiency and reducing the waste of resources caused by unqualified production. For example, the control device 120 can calculate the eccentricity of the composite metal wire 200 based on the relevant thickness-eccentricity algorithm and the thickness of the composite metal wire 200.

[0047] Refer to Figure 3, in one embodiment, taking the example that a plurality of ultrasonic probes 110 includes four ultrasonic probes 110, there is a 90° angle between adjacent ultrasonic probes 110.

[0048] In this embodiment, the four ultrasonic probes 110 are arranged at intervals of 90° around the composite metal wire 200, and the thicknesses of four corresponding positions of the composite metal wire 200 can be detected. The four ultrasonic probes 110 can be arranged on the same circumference with a point on the first plane in the first axial direction as the center.

[0049] Taking the aluminum-clad steel wire as an example, as Figure 3 and Figure 4 shown, the time for the detection pulse emitted by the ultrasonic probe 110 to be reflected back to the probe after reaching the surface of the aluminum layer of the aluminum-clad steel is T1, corresponding to Figure 5 the peak A in. The time for the detection pulse to be reflected back to the probe after reaching the surface of the steel layer is T2, corresponding to Figure 5 the peak B in. By calculating the difference between T1 and T2, the duration of the detection pulse transmitted in the aluminum layer can be determined: (T2 - T1) / 2. It can be understood that the thickness of the aluminum layer is proportional to the transmission duration. Therefore, by calculating the maximum and minimum values among the four transmission durations, the eccentricity of the cross-section of the aluminum-clad steel wire in the first plane at this moment can be obtained: (maximum transmission duration - minimum transmission duration) / maximum transmission duration. During the transmission of the aluminum-clad steel wire, the four ultrasonic probes 110 can send detection pulses according to a preset interval duration to detect the eccentricity of the aluminum-clad steel wire at different length positions.

[0050] Among them, the frequency of the detection pulse is 35 - 45 MHz. For example, the frequency of the detection pulse can be 40 MHz, and the number of pulses per second is 40 million times. During the aluminum-cladding process of the aluminum-clad steel, the running speed of the wire is 2 m / s, and the influence of the wire movement on the detection can be ignored. Therefore, the time T1 for the detection pulse to be reflected back to the probe after reaching the surface of the aluminum layer of the aluminum-clad steel can be equivalent to the time for the detection pulse to be emitted and reflected from the surface of the aluminum layer of the same cross-section of the wire. The time T2 for the detection pulse to be reflected back to the probe after reaching the surface of the steel layer can be equivalent to the time for the detection pulse to be emitted and reflected from the surface of the steel layer of the same cross-section of the wire. That is to say, T1 and T2 are the detection data for the same position on the wire and can be used to calculate the thickness parameters of this position. In this way, there are relatively clear peaks in the waveform of the detection pulse reflected back, so that the transmission duration of the detection pulse in the outer metal layer can be accurately determined, and the accuracy of the eccentricity can be improved.

[0051] In one embodiment, the aluminum-clad steel wire detection device 100 further includes a pre-wetting device 140. The pre-wetting device 140 has a second inlet, a second outlet, and a second accommodation cavity 141; the second inlet, the second outlet, the first inlet, and the first outlet are sequentially arranged on the first axial direction, and the second outlet is communicated with the first outlet; a coupling liquid is provided inside the pre-wetting device 140.

[0052] In this embodiment, the pre-wetting device 140 can be set as a trough for the composite metal wire 200 to pass through. A coupling liquid is provided in the trough to clean and pre-wet the surface of the composite metal wire 200, so that the composite metal wire 200 can be more easily covered by the coupling liquid after entering the ultrasonic detection device 130, increasing the coupling stability. Among them, the coupling liquid can be selected from water or an ultrasonic coupling agent. The second accommodation cavity 141 can be set as a closed cavity filled with the coupling liquid.

[0053] In one embodiment, the aluminum-clad steel wire detection device 100 further includes a protective baffle 150; the protective baffle 150 is arranged around the second inlet.

[0054] In this embodiment, the protective baffle 150 can be set as a cylindrical shape with a certain length. The protective baffle 150 can be designed with a metal material. The cross-section of the protective baffle 150 can be set to be slightly larger than the cross-section of the second inlet, so that the composite metal wire 200 can pass through, and at the same time, it can prevent foreign matters on the wire surface from entering. By arranging the protective baffle 150 at the second inlet, foreign matters during the production process can be prevented from entering the ultrasonic detection device 130. For example, during the aluminum coating process of the aluminum-clad steel wire, blocky alumina may be generated and adhered to the surface of the aluminum-clad steel wire. When passing through the protective baffle 150, the blocky alumina on the wire surface can be blocked by the protective baffle 150.

[0055] In one embodiment, the aluminum-clad steel wire detection device 100 further includes a straightening device 160. The straightening device 160 is arranged close to the pre-wetting device 140 on the first axial direction, and the straightening device 160 is arranged at an interval from the second inlet.

[0056] In this embodiment, the straightening device 160 includes a plurality of straightening wheels. The plurality of straightening wheels are used to guide the composite metal wire 200 to be transmitted to the pre-wetting device 140, and to correct and maintain the straightness of the composite metal wire 200, thereby improving the accuracy of the detection result.

[0057] In one embodiment, the aluminum-clad steel wire detection device 100 further includes a purging device 170. The purging device 170 is arranged close to the ultrasonic detection device 130 at the first outlet, and is used to clean the working liquid on the surface of the composite metal wire 200.

[0058] In this embodiment, the purging device 170 can be implemented by a wiper, a nozzle, and an air pump. The wiper can scrape off the coupling liquid and impurities adhering to the surface of the composite metal wire 200 through a rubber squeegee. The control device 120 can control the air pump to blow air through the nozzle to remove the coupling liquid on the surface of the composite metal wire 200, or control the air pump to suck air through the nozzle to remove the impurities on the surface of the composite metal wire 200.

[0059] In one embodiment, the aluminum-clad steel wire detection device 100 further includes an alarm device 180. The alarm device 180 is electrically connected to the control device 120, and the control device 120 is configured to control the alarm device 180 to output an alarm message when the thickness parameter of the composite metal wire 200 is outside a preset range. The thickness parameter includes a thickness value and / or an eccentricity.

[0060] In this embodiment, the alarm device 180 can include an audible and visual alarm. When the measured thickness value of the composite metal wire 200 is less than a preset threshold or the eccentricity exceeds a preset value, the control device 120 controls the audible and visual alarm to output an audible or visual alarm message to remind the staff to check. Among them, the thickness value can be the overall thickness of the composite metal wire 200 or the thickness of the outer cladding layer.

[0061] In one embodiment, the aluminum-clad steel wire detection device 100 further includes a display device 190. The display device 190 is electrically connected to the control device 120, and the display device 190 is configured to display the thickness parameter and the alarm message of the composite metal wire 200.

[0062] In this embodiment, the display device 190 can be implemented by a display screen, a digital tube, etc. The control device 120 can display the detection result and the alarm message through the display device 190.

[0063] Furthermore, the control device 120 can also record the material transfer number of each composite metal wire 200 in one-to-one correspondence with the thickness parameter / eccentricity for the background device to read. The staff can also set process parameters by operating the control device 120.
