Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, and particularly relates to an optical bracket for a flexible optical waveguide. Background Art

[0002] An optical waveguide is a structural member that guides the light emitted by an LED from a PCB to the front panel or the position where light emission is required. After the optical waveguides are mass-produced, it is necessary to sample and detect different batches of optical waveguides to measure whether the optical waveguides meet the production requirements.

[0003] Optical waveguides include rigid optical waveguides and flexible optical waveguides. The rigid optical waveguides only need to be installed and fixed on a bracket, while the flexible optical waveguides are relatively soft and cannot be detected using the traditional fixtures commonly used for rigid optical waveguides. In the prior art, when detecting a flexible optical waveguide, one end of the flexible optical waveguide needs to be fixed, and the other end is freely suspended. By relying on its own gravity, the optical waveguide is straightened. This detection method will cause the flexible optical waveguide itself to be rigidly stretched, increasing the probability of scrapping the flexible optical waveguide during the measurement process and increasing the measurement error.

[0004] In summary, how to provide a detection device for improving the measurement accuracy of flexible optical waveguides and having a low rejection rate has become a technical problem that needs to be urgently solved by those skilled in the art. Content of the Utility Model

[0070] For the optical bracket of the flexible optical waveguide of the present utility model, by providing the supporting ridge plate 4 for supporting the flexible optical waveguide 9, the flexible optical waveguide itself is prevented from being stretched rigidly, enabling the tested flexible optical waveguide 9 to be in a free length state and reducing the scrap rate. By providing the first input end fixing component 3 and the second input end fixing component 5 to stably fix the effective ends of the flexible optical waveguide 9, the reliability of the placement position of the flexible optical waveguide 9 is ensured, and the consistency of the effective length of the flexible optical waveguide 9 is guaranteed. The first incident end switching component 2 and the second incident end switching component 6 are provided to respectively fix the incident ends of the flexible optical waveguide 9, thereby improving the reliable alignment between the incident end of the flexible optical waveguide 9 and the light output end of the light source, and making the measurement result more reliable.

In order to facilitate the handling of the optical bracket of the present invention, a handle 11 is further provided on the support bottom plate 8. At least two handles 11 are provided, and the handles 11 are respectively arranged at both ends of the support bottom plate 8. In an embodiment, as Figure 2 shown, four handles 11 are provided, and two handles 11 are arranged at each end of the support bottom plate 8.

[0072] Specifically, the first input end fixing component 3 includes a first support frame 301 and a pressing mechanism 302 connected to the first support frame 301. Refer to Figures 3 to 5 . In order to limit the flexible optical waveguide 9, a first flexible optical waveguide limiting groove 3011 is provided on the first support frame 301. The pressing end of the pressing mechanism 302 is arranged corresponding to the first flexible optical waveguide limiting groove 3011, which is convenient for pressing the flexible optical waveguide 9 placed in the first flexible optical waveguide limiting groove 3011. Preferably, the pressing mechanism 302 is connected to the top surface of the first support frame 301. Correspondingly, the first flexible optical waveguide limiting groove 3011 is also arranged on the top surface of the first support frame 301. In order to facilitate the connection of the pressing mechanism 302, a first connection threaded hole 3012 is provided on the top surface of the first support frame 301. The pressing mechanism 302 is connected to the first connection threaded hole 3012 through a connection screw. In order to improve the connection reliability, four first connection threaded holes 3012 are preferably provided. In order to fix the first input end fixing component 3, a first connection through hole 3013 is provided at a position close to the bottom of the first support frame 301. Four first connection through holes 3013 are provided. By providing the first connection through holes 3013, it is convenient to connect the first support frame 301 to the support bottom plate 8. In order to reduce the structural weight, a second weight-reducing through hole 3014 is provided on the first support frame 301. It can be understood that the cavity of the first flexible optical waveguide limiting groove 3011 extends along the placing direction of the flexible optical waveguide 9. In order to facilitate quick pressing and releasing of the pressing, the pressing mechanism 302 is selected as a quick clamp. The quick clamp is a purchased part, and its structure will not be introduced in detail here. By providing the first flexible optical waveguide limiting groove 3011, it is convenient to control the pressing force and ensure the fixing stability of the flexible optical waveguide.

[0073] Among them, the structures of the first input end fixing component 3 and the second input end fixing component 5 are the same, and the structure of the second input end fixing component 5 will not be described here. Since the two structures are the same, it can reduce the processing and manufacturing costs while meeting the fixing requirements.

[0074] In an embodiment, the first light source component 1 includes a second support frame 101, an LED light source system 102 and a lens module 103, as Figure 6As shown.

At least one lens is provided on the lens module 103, and the light-emitting end of the lens is correspondingly arranged with the end of the flexible optical waveguide 9. During detection, only the light-incident end of the flexible optical waveguide 9 needs to be aligned with the lens on one lens module 103, and the other lenses are for backup.

Further, the limiting structure includes a cooperatively arranged upper fixing block 206 and a lower fixing block 205, as Figure 7 shown. The lower fixing block 205 is fixedly connected to the third support frame 201. The fixed connection here can be screw connection, bolt connection or welding. Limiting holes are provided on the contacting surfaces of the upper fixing block 206 and the lower fixing block 205. A flexible optical waveguide head 12 is provided at the end of the flexible optical waveguide 9. The inner wall of the limiting hole is conformally arranged with the outer surface of the flexible optical waveguide head 12. The flexible optical waveguide head 12 is placed in the limiting hole, and the upper fixing block 206 is pressed against the lower fixing block 205 to form positioning of the flexible optical waveguide head 12.

[0076] Further, the limiting hole includes a cooperatively arranged second flexible optical waveguide limiting groove 207 and a third flexible optical waveguide limiting groove 208. Both the second flexible optical waveguide limiting groove 207 and the third flexible optical waveguide limiting groove 208 are semi-groove holes. The second flexible optical waveguide limiting groove 207 is provided on the surface of the upper fixing block 206 close to the lower fixing block 205, and the third flexible optical waveguide limiting groove 208 is provided on the surface of the lower fixing block 205 close to the upper fixing block 206. When the upper fixing block 206 and the lower fixing block 205 are buckled together, the second flexible optical waveguide limiting groove 207 and the third flexible optical waveguide limiting groove 208 are spliced into the limiting hole. Among them, the cross-sections of both the second flexible optical waveguide limiting groove 207 and the third flexible optical waveguide limiting groove 208 are semi-circular, and when they are spliced, a cylindrical through-hole structure is formed.

[0077] In order to improve the reliability of the upper fixing block 206 and the lower fixing block 205 in limiting the flexible optical waveguide head 12, one ends of the upper fixing block 206 and the lower fixing block 205 are rotatably connected through a connecting pin shaft 211, and the other ends are detachably connected through a quick lock 202.

To reduce the structural weight, a third weight reduction through hole 210 is provided on the third support frame 201, as Figure 7 shown.

Referring to Figures 9 to 11 , the guiding plate body 401 extends along the placement direction of the flexible optical guide 9. The guiding plate body 401 is connected to the upper surface of the main board body 402. The width of the guiding plate body 401 is smaller than the width of the main board body 402, so as to reserve a placement position for the flexible optical guide 9. During use, the flexible optical guide 9 is placed on the main board body 402, and the flexible optical guide 9 is close to the side surface of the guiding plate body 401. The side surface of the flexible optical guide 9 is in contact with the side surface of the guiding plate body 401. The side surface of the guiding plate body 401 is used to guide the placement of the flexible optical guide 9, ensuring that the flexible optical guide 9 is placed in a straight line and ensuring the consistency of the effective length of the flexible optical guide 9. Specifically, the guiding plate body 401 is connected to the upper surface of the main board body 402 by screws.

[0081] In another embodiment, the guiding structure is a guiding groove 403. The guiding groove 403 is arranged on the main board body 402. Referring to Figure 12 shown, the guiding groove 403 extends along the placement direction of the flexible optical guide 9. The guiding groove 403 is arranged on the upper surface of the main board body 402. The flexible optical guide 9 is placed in the guiding groove 403, so as to realize the support and guidance of the flexible optical guide 9. Preferably, the groove depth dimension of the guiding groove 403 is greater than the diameter dimension of the flexible optical guide 9.

[0082] Specifically, in order to make the surface height of the support flexible optical guide 9 of the main board body 402 consistent with the surface heights of the first input end fixing component and the second input end fixing component for supporting the flexible optical guide 9, the support ridge plate 4 is connected to the support bottom plate 8 through the support column 10.

When disassembling the flexible optical guide 9, the first input end fixing component 3, the second input end fixing component 5, the first incident end switching component 2 and the second incident end switching component 6 are opened, and the whole flexible optical guide 9 can be taken off.

[0084] The optical bracket of the flexible optical guide of the present utility model uses a horizontal fixture to fix the flexible optical guide, reduces the scrap rate of the flexible optical guide, and has good consistency in measurement accuracy.
