[0001] The invention relates to a terminal assembly jig and an assembly method thereof, in particular to a terminal assembly jig of a coaxial optical fiber sensor and an assembly method thereof, and belongs to the technical field of optical fiber sensors. Background Art

[0002] With the continuous advancement of sensor technology, various types of sensors are widely used in various fields to meet the needs of object detection, measurement and identification. Coaxial sensors, as one of them, can measure and identify more accurately and reliably through their unique design and working principle. Therefore, they have been widely used in industrial automation, robotics, automobile manufacturing and other fields.

[0003] Secondly, the working principle of coaxial sensors is mainly based on optical principles, especially the principles of light reflection and scattering. By utilizing optical elements such as light sources, lenses, and detectors, coaxial sensors can achieve accurate measurement of object shape, position and other information.

[0004] In the existing technology, the terminals of coaxial sensors are usually connected by threaded connections, so a lot of time is consumed in the connection process, resulting in low installation efficiency. In addition, traditional terminals are fixed on the optical fiber by extrusion, so after long-term use, they will become loose, resulting in a significant reduction in detection efficiency and accuracy.

[0005] Therefore, there is an urgent need to improve the terminals and assembly jigs of coaxial fiber optic sensors to solve the above-mentioned problems. Summary of the invention

This method is quick, convenient and has high stability. At the same time, when the optical fiber terminal is installed on the sensor body, the optical fiber terminal can be directly fixed by the terminal fixing mechanism. This method has a simple structure and is quick and easy to install, thereby improving installation efficiency and detection accuracy.

[0015] A method for assembling a coaxial optical fiber sensor terminal assembly fixture comprises the following steps:

[0016] Step 1: Cut the insulation. Insert the optical fiber into the stripping mechanism on the stripping mechanism support ring. Rotate the stripping bolt as needed to increase the depth of the stripping knife.

[0017] Then, the stripping mechanism is driven to rotate by rotating the handle, and the stripping knife on the stripping bolt is used to cut the insulation on the optical fiber;

[0018] Step 2: Fixing the optical fiber, placing the optical fiber with the insulation removed on the optical fiber fixing mechanism and the terminal assembly mechanism on the assembly fixture, and then fixing the optical fiber through the optical fiber fixing mechanism;

[0039] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0041] A terminal fixing bin 101 is provided on a side of the second lens 104 away from the first lens 103, and an optical fiber terminal 3 is fixedly provided on the optical fiber 10. The optical fiber terminal 3 is clamped in the terminal fixing bin 101 through a terminal fixing mechanism 4. After the optical fiber terminal 3 is installed on the optical fiber 10, the optical fiber terminal 3 on the optical fiber 10 is directly plugged into the terminal fixing bin 101 of the sensor body 1. A terminal clamping groove 301 is provided on the optical fiber terminal 3. The terminal fixing mechanism 4 includes a U-shaped fixing part 401 and a fixing arm driving handle 402. The U-shaped fixing part 401 is slidably provided in the terminal fixing bin 101, and the bottom of the U-shaped fixing part 401 is The terminal clamp 407 is connected to the optical fiber terminal 3 through the clamp support arm 406, and the terminal clamp 407 is clamped in the terminal slot 301. After the optical fiber terminal 3 is inserted into the terminal fixing compartment 101, the terminal fixing compartment 401 in the terminal fixing compartment 101 is slid downward. When the terminal fixing compartment 401 slides downward, the terminal clamp 407 at the lower end of the clamp support arm 406 is clamped in the terminal slot 301 on the optical fiber terminal 3. On the one hand, the stability of the optical fiber terminal 3 is improved, and on the other hand, the optical fiber terminal 3 can be fixed by the terminal clamp 407. The structure is simple, which greatly improves the convenience and efficiency of installation.

[0042] In the process of pushing the U-shaped fixing member 401 downward, a driving groove 404 is opened on the U-shaped fixing member 401, and a bar-shaped driving tooth 405 is fixedly set on one side of the driving groove 404. A driving gear 403 meshing with the bar-shaped driving tooth 405 is fixedly set on one end of the fixed arm driving handle 402. The fixed arm driving handle 402 is used to vertically push the U-shaped fixing member 401. One end of the fixed arm driving handle 402 is rotatably connected to the inside of the terminal fixing bin 101, and the other end of the fixed arm driving handle 402 passes through the sensor body 1 and extends to the outside of the sensor body 1. By rotating the fixed arm driving handle set inside the terminal fixing bin 101, the fixed arm driving handle 402 is rotated. The handle 402 drives the driving gear 403 to rotate. When the driving gear 403 rotates, the bar-shaped driving tooth 405 meshing with the driving gear 403 moves upward or downward, thereby driving the U-shaped fixing member 401 to move upward or downward. When the U-shaped fixing member 401 moves downward, the terminal clamp 407 on the U-shaped fixing member 401 is clamped into the temporal part of the terminal clamping groove 301 and fixes the optical fiber terminal 3. When the U-shaped fixing member 401 moves upward, the terminal clamp 407 is disengaged from the terminal clamping groove 301 on the optical fiber terminal 3, so that the optical fiber terminal 3 and the optical fiber 10 can be taken out, thereby improving the convenience of use and the efficiency of installation.

[0043] At the same time, a first magnet groove 102 is provided inside the terminal fixing compartment 101, and a second magnet 13 is fixedly arranged inside the first magnet groove 102. A first magnet 302 corresponding to the second magnet 13 is fixedly arranged at one end of the optical fiber terminal 3, and the contact surfaces of the first magnet 302 and the second magnet 13 have opposite magnetic properties. The second magnet 13 is fixedly arranged inside the terminal fixing compartment 101, and after one end of the optical fiber terminal 3 is inserted into the terminal fixing compartment 101, the terminal slot 301 on the optical fiber terminal 3 and the second magnet 13 are close to each other under the action of magnetic force, so that the optical fiber terminal 3 can be positioned quickly and conveniently, thereby improving the efficiency of installation;

[0044] In addition, if Figure 1 and Figure 2 As shown, a sensor sealing plate 106 is fixedly provided at the upper end of the sensor body 1, a light receiving chamber 107 connected to the sensor sealing plate 106 is fixedly provided on the sensor sealing plate 106, a receiver 12 is fixedly provided on the light receiving chamber 107, a third lens 108 is fixedly provided at the lower port of the light receiving chamber 107, the sensor sealing plate 106 is fixedly provided on the upper end surface of the sensor body 1, the receiver 12 can receive the detection light through the reflection of the prism 105, so as to improve the detection efficiency, a third lens 108 is fixedly provided inside the light receiving chamber 107, and the third lens 108 has a converging effect on the light, so as to greatly improve the detection accuracy.

After the optical fiber 10 is fixed inside the rubber ring 502, the optical fiber cutting teeth 506 on the rubber ring 502 are against the surface of the optical fiber 10. Therefore, as long as the rubber ring 502 moves, scratches will be left on the surface of the optical fiber 10. A glue spraying head 507 is fixedly provided on the side of the rubber ring 502 away from the terminal extrusion block 501. The glue spraying head 507 is connected to a submersible pump through a water pipe. One side of the assembly fixture 2 is fixed to a glue storage box 9. The submersible pump is arranged inside the glue storage box 9. After the optical fiber cutting teeth 506 on the rubber ring 502 leave scratches on the outer surface of the optical fiber 10, glue is sprayed on the outer side of the optical fiber 10 through the glue spraying head 507. Since there are scratches on the surface of the optical fiber 10, it is easier to hang glue, further improving the stability of the optical fiber terminal 3;

[0046] During the installation of the optical fiber terminal 3, the optical fiber terminal 3 is sleeved on the optical fiber 10, and then the terminal extrusion block 501 is abutted against each other. After the optical fiber terminal 3 is placed on the terminal assembly mechanism 5, the electric telescopic rod 504 on the terminal assembly mechanism 5 is started to squeeze the optical fiber terminal 3 and the optical fiber 10. During the squeezing, the optical fiber scratching teeth 506 on the glue coating ring 502 scratch the optical fiber 10, and the glue spraying head 507 sprays glue. After the glue spraying is completed, the optical fiber terminal 3 is installed. The structure is simple, which is convenient for installing the optical fiber terminal 3 and can improve the stability of the optical fiber terminal 3.

[0047] like Figure 6As shown, electric telescopic rods 504 are fixedly connected to both sides of the terminal extrusion block 501, and the electric telescopic rods 504 are fixedly arranged on the upper side of the assembly fixture 2 through the telescopic rod fixing block 508.

When the terminal assembly mechanism 5 is driven by the electric telescopic rod 504, the assembly mechanism guide plate 505 on the terminal extrusion block 501 is slidably arranged inside the guide slot 202, and the guide slot 202 plays a certain guiding role on the assembly mechanism guide plate 505, thereby improving the stability of the movement of the terminal assembly mechanism 5;

The stripping mechanism support ring 6 is fixedly provided on the upper side of the assembly fixture 2 through a stripping mechanism support column 602. A slide groove 601 is provided on the outer side of the stripping mechanism support ring 6. A C-shaped clamping claw 701 slidably connected to the slide groove 601 is fixedly provided on the stripping mechanism 7, and a rotating handle 702 is fixedly provided on one of the C-shaped clamping claws 701. A stripping mechanism 7 is rotatably provided on one side of the terminal assembly mechanism 5 through the stripping mechanism support ring 6. The stripping mechanism 7 can strip the optical fiber 10, which is convenient for the later installation of the optical fiber terminal 3 and improves the convenience of use. A stripping bolt 703 is rotatably provided on the stripping mechanism 7, and one end of the stripping bolt 703 passes through the stripping mechanism 7 and is connected to a stripping knife 704. The stripping knife 704 abuts against the outer side of the optical fiber 10, specifically:

[0049] One end of the optical fiber 10 is inserted into the stripping mechanism 7 on the stripping mechanism support ring 6, and then the stripping bolt 703 on the stripping mechanism 7 is rotated to increase the distance between the optical fiber 10 and the stripping mechanism 7, and then the stripping mechanism 7 is rotated by the rotating handle 702 on the stripping mechanism 7 to perform rotary cutting on the outer side of the optical fiber 10. After the stripping knife 704 on the stripping bolt 703 cuts the insulation layer of the optical fiber 10, the cut insulation layer can be removed from the optical fiber 10.

[0050] In addition, a fiber optic fixing mechanism 8 is fixedly provided on one side of the stripping mechanism support ring 6. The fiber optic fixing mechanism 8 is used to clamp the optical fiber 10. The fiber optic fixing mechanism 8 includes a fixed clamp 801 and a movable clamp 802. The movable clamp 802 corresponds to the fixed clamp 801. The movable clamp 802 is fixedly connected with an electric clamp telescopic rod 803. The electric clamp telescopic rod 803 is fixedly arranged inside the assembly fixture 2. When the terminal assembly mechanism 5 fixes the optical fiber terminal 3, the terminal extrusion block 501 on the terminal assembly mechanism 5 will squeeze the optical fiber 10. Therefore, multiple optical fibers 10 need to be fixed. The fixed clamp 801 on the fiber optic fixing mechanism 8 is fixed on the assembly fixture 2, and the movable clamp 802 slides on the assembly fixture 2. The movable clamp 802 is fixedly connected with the electric clamp telescopic rod 803.

[0057] Then, the surface of the optical fiber 10 is sprayed with glue through the electric telescopic rod 504 on the glue coating ring 502;

[0058] Finally, the optical fiber terminal 3 is fixed on the sensor body 1 under the action of the terminal extrusion block 501 , and the assembly of the optical fiber terminal 3 is completed.
