[0032] Please refer to Figure 1 and Figure 2 The present embodiment discloses an optical fiber detection device, including a bracket 100, a camera assembly 200, a mirror assembly 300 and a light source 400. The camera assembly 200 is mounted on the bracket 100. The camera assembly 200 includes a first camera 210, a second camera 220 and a camera lens 230. The axis of the first camera 210 and the axis of the second camera 220 are arranged vertically and horizontally respectively. The first camera 210 and the second camera 220 are both connected to the camera lens 230. The camera lens 230 is located inside and between the first camera 210 and the second camera 220. 0, a reflector is installed at the intersection of the optical paths of the first camera 210 and the second camera 220. For example, the axis of the first camera 210 is arranged in the longitudinal direction, and the axis of the second camera 220 is arranged in the transverse direction. The first camera 210 and the second camera 220 share the same camera lens 230, and the optical path is changed by the reflector arranged in the lens. For example, the reflector forms an angle of 45° with the horizontal plane, and the reflective surface of the reflector faces the second camera 220, so that the first camera 210 can shoot through the reflector, and the second camera 220 can shoot the image reflected by the reflector. It should be noted that the reflector adopts an existing product, which will not be described in detail in this embodiment. The mirror assembly 300 is mounted on the bracket 100 and is located below the camera lens 230. The mirror assembly 300 is provided with a first mirror 311 and a second mirror 321. The first mirror 311 and the second mirror 321 are distributed on both sides of the axis of the camera lens 230, and the first mirror 311 and the second mirror 321 are both inclined toward the direction of the camera lens 230. A detection space 301 is formed between the first mirror 311 and the second mirror 321. The light source 400 is mounted on the bracket 100 and is located between the camera assembly 200 and the mirror assembly 300.
[0033] During the inspection, the optical fiber is placed in the inspection space 301, and one of the first camera 210 or the second camera 220 is used to capture the front image of the optical fiber, and the other of the first camera 210 or the second camera 220 is used to capture the image reflected by the optical fiber through the first mirror 311 and the second mirror 321, so that images of the optical fiber at multiple angles can be captured, thereby performing a quality inspection on the coating on the surface of the optical fiber. In this embodiment, by setting the first camera 210 and the second camera 220 that share the camera lens 230, the focal lengths of the first camera 210 and the second camera 220 can be adjusted respectively, so that the first camera 210 can clearly capture the front image of the optical fiber, and the second camera 220 can clearly capture the reflected image of the first mirror 311 and the second mirror 321, thereby avoiding the single camera being unable to detect the back of the optical fiber, wherein the light source 400 can provide sufficient brightness for image capture, so that the coating defects on the surface of the optical fiber can be clearly displayed on the image, for example, when the coating is stained or broken, a significant difference in light and dark can be observed on the image, thereby performing a quality inspection on the coating on the surface of the optical fiber.
[0034] Please refer to Figure 3 The mirror assembly 300 includes a first lens 310, a second lens 320, a first mounting block 330, and a second mounting block 340. The first mirror surface 311 is arranged on the first lens 310, the second mirror surface 321 is arranged on the second lens 320, the first lens 310 is mounted on the first mounting block 330, and the second lens 320 is mounted on the second mounting block 340. Exemplarily, both the first lens 310 and the second lens 320 can be prisms, and one of the multiple faces of the prism is selected as the first mirror surface 311 or the second mirror surface 321. The first mounting block 330 and the second mounting block 340 are distributed on opposite sides of the axis of the camera lens 230, so that the first lens 310 and the second lens 320 are arranged relative to each other to form a detection space 301 between the first mirror surface 311 and the second mirror surface 321.
[0035] Please continue to refer to Figure 3 The mirror assembly 300 further includes a first slide rail 350 and a second slide rail 360, the first mounting block 330 is slidably mounted on the first slide rail 350, and the second mounting block 340 is mounted on the second slide rail 360. In this way, the position of the first mounting block 330 can be adjusted along the first slide rail 350, and the position of the second mounting block 340 can be adjusted along the second slide rail 360, so that the first camera 210 or the second camera 220 can capture a clear reflected image.
[0036] Please continue to refer to Figure 3A first height adjustment component 370 is connected between the mirror assembly 300 and the bracket 100, which can adjust the installation height of the mirror assembly 300 on the bracket 100, thereby adjusting the height of the first mirror 311 and the second mirror 321 relative to the bracket 100, so that the first camera 210 or the second camera 220 can capture a clear reflected image.
[0037] Please refer to Figure 4 In order to realize continuous detection of optical fiber, a tensioning assembly is also installed on the bracket 100. During detection, the rolled optical fiber is arranged on the supply tray, and is pulled by the receiving tray, and the optical fiber is tensioned by the tensioning assembly, so that the optical fiber is continuously and automatically fed. It should be conceived that the tensioned optical fiber passes through the detection space 301, so as to be continuously detected.
[0038] Please continue to refer to Figure 4 The tensioning assembly includes a first tensioning wheel set 510 and a second tensioning wheel set 520, which are distributed on opposite sides of the mirror assembly 300. The first tensioning wheel set 510 and the second tensioning wheel set 520 can be arranged with one or more tensioning wheels to tension the optical fiber.
[0039] A guiding assembly is also installed on the bracket 100 , and the guiding assembly can guide the optical fiber in at least one direction of the height direction and the horizontal direction, so that the optical fiber can smoothly pass through the detection space 301 .
[0040] For example, please refer to Figure 4 The guide assembly includes a height guide assembly 610 and a horizontal guide assembly 620. The height guide assembly 610 is installed on the adjacent side of the horizontal guide assembly 620. The height guide assembly 610 is used to guide the optical fiber in the height direction so that the height position of the optical fiber meets the requirements, and the horizontal guide assembly 620 is used to guide the optical fiber in the horizontal direction so that the horizontal position of the optical fiber meets the requirements. In this way, through the cooperation of the height guide assembly 610 and the horizontal guide assembly 620, the optical fiber can smoothly pass through the detection space 301.
[0041] Specifically, the height guiding assembly 610 includes a first guiding roller 611 and a second guiding roller 612, which are arranged in the longitudinal direction. When in use, the optical fiber passes through the gap between the first guiding roller 611 and the second guiding roller 612, and the optical fiber is guided in the height direction through the cooperation of the first guiding roller 611 and the second guiding roller 612. The second guiding roller 612 can be installed on the second height adjustment assembly 613, so as to adjust the distance between the first guiding roller 611 and the second guiding roller 612.
[0042] The horizontal guiding assembly 620 includes a first guiding wheel 621 and a second guiding wheel 622. The side walls of the first guiding wheel 621 and the second guiding wheel 622 are both provided with an annular guiding groove 623. When in use, the optical fiber is wound around the first guiding wheel 621 and the second guiding wheel 622 and embedded in the corresponding guiding groove 623, so as to guide the position of the optical fiber in the horizontal direction so that the optical fiber meets the horizontal position requirement.
[0043] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
