[0026] See also Figure 2 In a first aspect of an embodiment of the present application, a wire material detection device 10 is provided. The wire material detection device 10 includes at least one detection platform 100. The detection platform 100 is used to carry wire materials. The wire materials here are, for example, USB (Universal Serial Bus) cables, specifically, USB cables with Type-C interfaces. The carrying here is, for example, that the entire wire material is placed on the detection platform 100, or that the interface part of the wire material is placed on the detection platform.
[0027] At least one sensing mechanism 200 is disposed near the detection platform 100 and is used to sense that the wire is placed on the detection platform 100. The sensing mechanism 200 here is, for example, some optical sensors. The sensing mechanism 200 can be fixedly disposed on the detection platform 100 or can be separated from the detection platform 100. However, it can be understood that the effective sensing range of the sensing mechanism 200 can cover the detection platform 100 to sense the position of the wire.
[0028] At least one fixing mechanism 300 is disposed on the detection platform 100 and is used to press the wire onto the detection platform 100 when the wire is placed on the detection platform 100 .
[0029] The first camera 400 is used to obtain the first image of the wire, and the second camera 500 is used to obtain the second image of the wire, that is, the shooting ranges of the first camera 400 and the second camera 500 correspond to different positions of the wire, respectively, to obtain the first image and the second image of the wire, and the controller 600 obtains the measurement result according to the first image and the second image. It can be understood that the first camera 400 and the second camera 500 can transmit the first image and the second image to the controller 600 by wired or wireless transmission. The measurement result here is, for example, qualified / unqualified, that is, the measurement result is used to indicate whether the quality of the wire is qualified.
[0030] In some embodiments, the controller 600 is, for example, a PLC (Programmable Logic Controller).
[0031] The wire detection device 10 provided in the embodiment of the present application senses whether the wire is placed on the detection platform 100 through the sensing mechanism 200, and presses and fixes the wire on the detection platform 100 by setting the fixing mechanism 300 when the wire is placed on the detection platform 100, and obtains the first image and the second image of the wire through the first camera 400 and the second camera 500, and the controller 600 obtains the detection result of the wire according to the first image and the second image, thereby improving the detection stability and detection efficiency and improving the accuracy of the detection result.
[0032] See also Figure 2 and Figure 3 In one embodiment, the wire detection device 10 further includes a reflector 700, which is used to reflect a second image of the wire. The reflector 700 may be disposed above the detection platform 100. Specifically, the reflective angle of the reflector 700 is, for example, 90°.
[0033] In some embodiments, the reflective member 700 may be a reflective prism.
[0034] See also Figure 2 and Figure 3 In one embodiment, the shooting directions of the first camera 400 and the second camera 500 are parallel, that is, the lens directions of the first camera 400 and the second camera 500 are parallel to each other, which facilitates the installation of the first camera 400 and the second camera 500. In some embodiments, the first camera 400 and the second camera 500 are installed in sequence in a vertical direction.
[0035] See also Figure 2 and 3 In one embodiment, the first image includes the PIN information of the wire interface. The second image includes the size information of the wire interface, and the second image includes the length dimension of the wire interface. The viewing angles of the first image and the second image are perpendicular to each other, that is, the first image and the second image are image information obtained from two perpendicular directions of the wire. It can be understood that the controller 600 can identify the number and size of the PINs and the length of the wire interface based on the first image and the second image to detect whether the wire is qualified.
[0036] See also Figure 2 and 3 In one embodiment, the sensing mechanism 200 includes a fiber optic sensor. When the fiber optic sensor senses that a wire is placed on the detection platform 100, the position state of the wire is converted into an optical signal and sent to the controller 600. The controller 600 can then control the fixing mechanism 300 to compress the wire.
[0037] In some embodiments, the sensing mechanism 200 may also use other forms of sensors, such as a pressure sensor.
[0038] See also Figure 2 and 3 In one embodiment, the fixing mechanism 300 may be a cylinder, which is disposed on the detection platform 100. The cylinder is used to apply pressure to the wire when the wire is placed on the detection platform 100, so as to press the wire tightly on the detection platform 100, and the cylinder stops applying pressure to the wire when the controller 600 obtains the measurement result.
[0039] See also Figure 2 and 3 In one embodiment, the wire detection device 10 further includes a first light source 800 and a second light source 900, and the first light source 800 and the second light source 900 are used to illuminate the wire from different angles respectively to improve the brightness of the first image and the second image. Specifically, the first light source 800 illuminates the wire interface direction to improve the brightness of the first image, and the second light source 900 is used to illuminate above the wire to improve the brightness of the second image. In some embodiments, the first light source 800 is disposed in front of the lens of the first camera 400, and the second light source 900 is disposed in front of the lens of the second camera 500. The first light source 800 and the second light source 900 can be ring lights.
[0040] See also Figure 2 and 3 In one embodiment, the focal lengths of the first camera 400 and the second camera 500 are fixed preset focal lengths, the positions of the first camera 400 and the second camera 500 are fixed, and the focal lengths of the first camera 400 and the second camera 500 are also fixed. In this way, a fixed calculation method is used to quickly obtain the detection results through the first image and the second image, thereby improving the detection efficiency. In addition, the detection platform 100 has a jack, which is used to carry the wire and limit the insertion depth of the wire. By setting the jack, the placement and positioning of the wire is facilitated.
[0041] See also Figure 2 , 3 , 4 and 5, in one embodiment, the wire has a first interface and a second interface, i.e., interfaces at both ends of the wire, and the number of the detection platform 100, the sensing mechanism 200, the first camera 400 and the second camera 500 of the wire detection device 10 are all two.
[0042] The two detection platforms 100 are used to carry the first interface and the second interface of the wire respectively. The two sensing mechanisms 200 are used to sense the first interface and the second interface of the wire respectively. The two first cameras 400 are used to obtain the first images of the first interface and the second interface of the wire respectively. The two second cameras 500 are used to obtain the second images of the first interface and the second interface of the wire respectively. Figure 4 and 5The wire detection device 10 has two detection platforms 100, namely, a jig A and a jig B. In this way, when performing wire detection, both ends of a wire can be inserted into the jig A and the jig B respectively, or two wires can be inserted into the jig A and the jig B respectively, so as to further improve the detection efficiency.
[0043] Understandably, see Figure 5 , the first camera 400 is set in the lower layer, the number is two, the second camera 500 is set in the upper layer, the number is two, and correspondingly, the first light source 800 is set in the lower layer, the number is two, and the first light source 800 is set in the upper layer, the number is two. In some embodiments, only one sensing mechanism 200 can be used, that is, one sensing mechanism 200 simultaneously detects the placement of wires on two detection platforms 100. In some embodiments, only one fixing mechanism 300 can be used, that is, one fixing mechanism 300 simultaneously fixes the wires of two detection platforms 100.
[0044] The wire detection device 10 provided in the embodiment of the present application senses whether the wire is placed on the detection platform 100 through the sensing mechanism 200, and when the wire is placed on the detection platform 100, the wire is pressed and fixed on the detection platform 100 through the fixing mechanism 300, and the first image and the second image of the wire are acquired through the first camera 400 and the second camera 500. The controller 600 obtains the detection result of the wire according to the first image and the second image, thereby improving the stability of the detection and the accuracy of the detection result. The detection time for each time is between 1-2 seconds, which greatly shortens the detection time and improves the detection efficiency.
[0045] A second aspect of the embodiments of the present application provides a wire detection device, including the wire detection device 10 provided in the first aspect of the embodiments of the present application.
