[0045] In conventional fiber optic pump production testing, one end of the fiber needs to be inserted into the integrating sphere for testing. Therefore, it is usually required that one end of the fiber extend beyond one end of the fixed plate. In this state, because one end of the fiber is exposed outside the fixed plate, it is very easy to bump or knock the fiber during actual production, thereby affecting the testing structure of the pump structure.

[0046] This invention proposes a fiber-optic testing structure 100 to solve the above problems.

[0047] Please see Figures 1 to 3 In one embodiment of this utility model, the fiber testing fiber-shifting structure 100 includes a frame base, a pump fixing fixture 2, a fiber fixing part, and a shifting structure 5. The pump fixing fixture 2 is mounted on the frame base and includes a fixing plate 21. The fiber fixing part includes a clamping part 4 for clamping and fixing the fiber. The clamping part 4 is movably mounted on the fixing plate 21 along a first direction and has a retracted position and an extended position on the fixing plate 21. The shifting structure 5 is mounted on the frame base on one side corresponding to the fixing plate 21 to drive the clamping part 4 to move between the retracted position and the extended position. Corresponding to the retracted position, the fiber end on the clamping part 4 is located inside the fixing plate 21; corresponding to the extended position, the fiber end on the clamping part 4 extends outside the fixing plate 21.

[0048] In actual testing of the pump structure, the pump structure is mounted on the pump fixture 2. The optical fiber structure on the pump structure is fixed at the position of the fixing plate 21. When testing the pump structure, one end of the optical fiber needs to extend into the integrating sphere for testing, so it is usually required that one end of the optical fiber extend beyond one end of the fixing plate 21. In this state, since one end of the optical fiber is exposed outside the end of the fixing plate 21, it is very easy to cause bumps and knocks to one end of the optical fiber during actual production, thereby affecting the testing structure of the pump structure.

[0049] Considering the above problems, in the above embodiment, the clamping part 4 for fixing the optical fiber is set as a movable structure. Specifically, as described above, the clamping part 4 is movable in the first direction. Before actual testing, one end of the optical fiber is fixed on the clamping part 4. Before testing, the clamping part 4 can be positioned at the retracted position, so that one end of the optical fiber can be located inside the fixing plate 21. During the actual transfer of the pump fixing fixture 2, the risk of impact to the end of the optical fiber can be greatly reduced. When the pump structure is fixed on the frame base and needs to be tested, the actuating structure 5 starts to work. The output end of the actuating structure 5 moves to the position of the clamping part 4 and connects with the clamping part 4, thereby driving the clamping part 4 to move from the retracted position to the extended position in the first direction. At this time, one end of the optical fiber can extend outward from one end of the fixed plate part 21 by a certain length to meet the measurement requirements of the integrating sphere. After the test is completed, the actuating structure 5 drives the clamping part 4 to move from the extended position to the retracted position, so that one end of the optical fiber is located inside the fixed plate part 21 in the non-test state, thereby protecting one end of the optical fiber.

[0050] In the above structure, the clamping part 4 firstly provides protection for the optical fiber test end, greatly improving the yield during the testing process. Simultaneously, the actuating structure 5 enables automatic delivery and retrieval of the optical fiber without human intervention, effectively improving production efficiency in actual production processes.

[0051] In one embodiment of this solution, the clamping part 4 includes a bottom slider 41 and a flip cover 42. The bottom slider 41 is slidably mounted on the fixing plate part 21 along the first direction, and a limiting groove 411 is provided on the upper end surface of the bottom slider 41 for accommodating the optical fiber. The flip cover 42 is rotatably mounted on the bottom slider 41 corresponding to one side of the limiting groove 411 for pressing and fixing the optical fiber within the limiting groove 411.

[0052] The clamping part 4 uses a pressing method to fix the end of the optical fiber. Specifically, when fixing the optical fiber, a portion of the fiber end is placed in the limiting groove 411 for positioning. The limiting groove 411 is a V-shaped groove, and its two inclined surfaces can keep the optical fiber in the center position as much as possible. After the optical fiber is placed, the flip cover 42 is flipped so that one end of the flip cover 42 presses down on the optical fiber, thereby preventing the optical fiber from coming out of the limiting groove 411.

[0053] It is conceivable that the flip cover 42 can use its own weight to press down and fix the optical fiber. To ensure the pressing and fixing effect of the flip cover 42, a corresponding snap-fit ​​structure or magnetic attraction structure can be provided between the flip cover 42 and the bottom slider 41, so that the flip cover 42 can simultaneously achieve the connection effect with the bottom slider 41 when it is in the pressed state, thereby improving the fixing effect of the optical fiber.

[0054] Furthermore, in order to reduce damage to the optical fiber structure, a corresponding flexible material can be appropriately provided on the pressing surface of the limiting groove 411 and the flip cover 42.

[0055] In one embodiment of this application, to ensure the stability of the bottom slider 41 during movement, a corresponding guide motion structure is also provided on the fixed plate portion 21. Specifically, the fiber fixing portion further includes a guide plate portion 211; the guide plate portion 211 is mounted on the fixed plate portion 21, the bottom slider 41 is slidably mounted on the guide plate portion 211 along the first direction, and a connecting portion is provided between both ends of the bottom slider 41 and the guide plate portion 211 for fixing the bottom slider 41 at the retracted position and the extended position.

[0056] In the above embodiment, the guide plate portion 211 is located at one end of the fixed plate portion 21, and the length direction of the guide plate portion 211 extends along the first direction. During the actual movement of the bottom slider 41, it switches between the retracted position and the extended position along the extension direction of the guide plate portion 211. It is conceivable that when the optical fiber is in the retracted and extended positions, it needs to remain stable in its current position to achieve the corresponding protective effect and ensure the accuracy of the test results. In the above embodiment, the connection portion prevents the bottom slider 41 from undergoing relative movement without external force when in the retracted and extended positions. This ensures the positional stability of the optical fiber during storage and testing.

[0057] The guide plate portion 211 has protrusions 2111 on both ends in the first direction; the connecting portion includes a first magnetic attraction portion (not shown in the figure) provided on the opposite end faces of the two protrusions 2111, and two second magnetic attraction portions 32 provided on both ends of the bottom slider 41 opposite to the two first magnetic attraction portions.

[0058] like Figure 2 As shown, the retracted position and the extended position are located at the two ends of the guide plate 211, respectively. When the bottom slider 41 moves inward toward the fixed plate 21 to one end of the guide plate 211, that is, when it is in the retracted position, the second magnetic attraction part 32 on the end of the bottom slider 41 engages with the first magnetic attraction part, ensuring the stability of the bottom slider 41 in the retracted position. During testing, the actuating structure 5 drives the bottom slider 41 to move toward the other end of the fixed plate 21. After the first magnetic attraction part and the second magnetic attraction part 32 engage, the bottom slider 41 can also maintain positional stability in the extended position.

[0059] In the above embodiments, a magnetic structure is used as the position fixing structure of the bottom slider 41. This is because the magnetic structure is relatively simple, and the fixing and separation of the bottom slider 41 and the guide plate 211 can be achieved by the toggle structure 5 in the first direction without human intervention. The operation is simple and easy to implement, which can improve the automation level of the production process to a certain extent.

[0060] Typically, pump structures include long optical fiber structures, with the fiber length being much longer than the entire length of the pump fixing fixture 2. To fix the excessively long fiber, it needs to be coiled. Therefore, in this embodiment, a fiber coiling groove 212 is formed in the recessed portion of the fixing plate 21, and a limiting post 2121 is provided at the bottom of the groove; a rotating pressure strip 213 is provided on the fixing plate 21, and one end of the rotating pressure strip 213 is positioned corresponding to the limiting post 2121.

[0061] like Figure 1 and Figure 2As shown, a circular fiber coiling groove 212 is formed on the fixing plate 21. During fiber coiling, the optical fiber is typically placed within the fiber coiling groove 212. The coiled optical fiber is horizontally limited by the limiting post 2121. Then, the exposed length of the optical fiber is adjusted to fix its end to the clamping part 4. After fixing, the rotating pressure strip 213 is flipped over, and one end of the rotating pressure strip 213 contacts one end of the limiting post 2121, thereby limiting the coiled optical fiber in the vertical direction, preventing the optical fiber from warping and improving the stability of the fixed optical fiber.

[0062] It should be noted that, in order to avoid the impact of the coiled optical fiber on the optical fiber structure, the fiber coiling groove 212 can be set to be relatively large within the allowable range of the fixing plate 21. Furthermore, the structure of the rotating pressure strip 213 can be adapted to include multiple strips, thereby improving the fixing effect on the optical fiber structure.

[0063] In one embodiment of this application, the actuating structure 5 includes an actuating head 51 and a driving assembly 52. ​​The driving assembly 52 is mounted on the frame base and connected to the actuating head 51 to drive the actuating head 51 to move along a first direction and a second direction; wherein the second direction is perpendicular to the first direction in a horizontal plane.

[0064] As described above, the drive component 52 can move in two mutually perpendicular directions in the horizontal plane. When the drive component 52 moves, it can drive the actuating head 51 to move in the first direction, and at the same time, it can achieve contact and separation with the actuating head 51.

[0065] The frame base is provided with a first frame portion 11, which includes a horizontal frame portion 111 and a vertical frame portion 112. One end of the actuating head 51 is provided with a sliding rod portion 512, which is slidably mounted on the upward end of the vertical frame portion 112 along the second direction. The driving assembly 52 includes a first driving portion 521 and a second driving portion 522. The first driving portion 521 is mounted on the frame base, and its output end is movably disposed along the first direction. The horizontal frame portion 111 is disposed on the output end of the first driving portion 521. The second driving portion 522 is mounted on the horizontal frame portion 111, and its output end is connected to the sliding rod portion 512 to drive the sliding rod portion 512 to move in the second direction.

[0066] like Figure 3As shown, in the above structure, when the first driving part 521 moves, it can drive the second driving part 522 to move in the first direction through the horizontal frame part 111 connected to it. In this movement state, the movement of the toggle head 51 in the first direction can be realized simultaneously. The slide bar part 512 is arranged along the second direction. During the movement of the second driving part 522, the slide bar part 512 can be driven to move in the second direction simultaneously, thereby realizing the contact and separation of the toggle head 51 and the bottom slider 41.

[0067] In the above embodiments, both the first drive unit 521 and the second drive unit 522 are horizontal drive structures, which can be configured as cylinder structures, electric actuator structures, or hydraulic cylinder structures, etc. The configuration can be selected according to the actual production conditions.

[0068] Meanwhile, because the slide bar 512 has a certain extension length, if a direct drive structure is used to connect its end for driving, the extension length of the entire structure will be too large, which may cause interference with external structures when used in the whole machine. Considering the above problems, this solution adopts a partial structure for transition, so as to control the overall space occupied by the entire toggle structure 5 as small as possible. Specifically, the horizontal frame 111 is provided with a support arm 1112 rotatably connected thereto, and a connecting shaft 1113 is provided at the middle position of the support arm 1112. The output end of the second drive unit 522 is rotatably connected to the connecting shaft 1113 to drive the support arm 1112 to rotate on the horizontal frame 111. A guide block 513 is provided at the end of the slide bar 512 away from the toggle head 51, and a guide groove 5131 is opened on the guide block 513 along the vertical direction. The end of the support arm 1112 away from the horizontal plate is slidably installed in the guide groove 5131.

[0069] By configuring the above structure, the second drive unit 522 can be disposed on the upper end surface of the horizontal frame 111, and the travel stroke of the second drive unit 522 and the travel stroke of the guide rod can overlap in the first direction, effectively reducing the extension length of the second drive unit 522 in the second direction. Specifically, during the operation of the first drive unit 521, it will drive the support arm 1112 to swing around the axis in the first direction on the horizontal frame 111. During the swinging of the distal end of the support arm 1112, it moves within the guide groove 5131 and can simultaneously apply a force in the second direction to the guide block 513, thereby driving the guide rod to move in the second direction, so as to achieve the contact and separation of the actuating head 51 and the bottom slider 41.

[0070] In another embodiment of this application, the frame base is provided with a second frame portion 12, the first frame portion 11 is slidably mounted on the second frame portion 12 along the first direction, and the first drive portion 521 is mounted on the second frame portion 12.

[0071] like Figure 3 As shown, the arrangement of the first frame 11 and the second frame 12 allows the first drive unit 521 and the second drive unit 522 to be substantially located within the area encompassed by the first frame 11 and the second frame 12. The entire structure does not have a large spatial span in the first or second direction. This significantly improves the compactness of the entire actuation structure 5. In particular, when the above structure is applied to the overall machine structure, it can minimize interference between the actuation structure 5 and the external structure.

[0072] To ensure good contact between the actuating head 51 and the bottom slider 41 during the movement of the actuating head 51, the clamping part 4 includes a bottom slider 41, which is slidably mounted on the fixing plate part 21 along the first direction; a retaining protrusion 412 is formed on the bottom slider 41; the actuating head 51 is recessed inward at one end corresponding to the retaining protrusion 412 to form a retaining groove 511, which is used to accommodate the retaining protrusion 412.

[0073] As the second driving unit 522 drives the actuating head 51 to move toward the bottom slider 41 in the second direction, the slot portion 511 can engage with one end of the retaining protrusion 412. This prevents the bottom slider 41 from dislodging from one end of the actuating head 51 during movement, thereby improving the stability when the actuating head 51 and the bottom slider 41 are in contact.

[0074] It is conceivable that, in addition to the aforementioned protrusion and slot structures, there are many other corresponding interlocking structures, and even the corresponding ends of both can be designed as irregular shapes, etc., which can be set according to the actual situation.

[0075] The aforementioned actuation structure 5, firstly, possesses excellent structural compactness and occupies relatively little space, making it suitable for most space-constrained dual-axis drive structures. Regarding this solution, it effectively replaces manual adjustment of the fiber optic end position, thereby significantly improving the overall equipment efficiency and demonstrating promising application prospects.

[0076] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
