For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0046] like Figures 1 to 4As shown, an embodiment of the present invention provides an optical waveguide testing device, which includes a testing device 10, a mounting support 1, a first rotating mechanism 2, a second rotating mechanism 3, a support 4 and a light source assembly 5. The testing device 10 is provided with a shooting element 11 extending along a first direction X, and the mounting support 1 is provided with a rotating shaft 12 extending along a second direction Y. The shooting element 11 and the rotating shaft 12 are perpendicular to each other in a horizontal plane; the first rotating mechanism 2 includes a first guide rail 21, and the first guide rail 21 is annular. The shooting element 11 is penetrated by the first guide rail 21 and is rotatably connected to the first guide rail 21. The guide rail 21 can rotate around the shooting element 11 to form a spherical area; the second rotating mechanism 3 includes a second guide rail 31, the second guide rail 31 is semicircular, the second guide rail 31 is rotatably connected to the rotating shaft 12, and the second guide rail 31 can rotate around the center of the spherical area with the rotating shaft 12 as the central axis; the support member 4 is arranged at the center of the spherical area, the support member 4 is used to fix the optical waveguide lens 6, and the shooting element 11 faces the optical waveguide lens 6; the light source component 5 is slidably connected to the first guide rail 21 and the second guide rail 31, and the light source component 5 is used to emit light to the optical waveguide lens 6.

[0047] In this embodiment, if Figure 1 As shown, the mounting support 1 has a first direction X, a second direction Y and a third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0048] The mounting support 1 is a supporting structure of the entire optical waveguide test device, the test device 10 is mounted and fixed on the mounting support 1, the shooting element 11 of the test device 10 extends along the first direction X, the rotating shaft 12 on the mounting support 1 extends along the second direction Y, and the shooting element 11 and the rotating shaft 12 are perpendicular to each other on the horizontal plane formed by the first direction X and the second direction Y. The shooting element 11 faces the optical waveguide lens 6 and is used to shoot the rainbow effect on the surface of the optical waveguide lens 6. The shooting element 11 can be a camera or other equipment that can shoot diffraction images.

[0049] The first guide rail 21 is a circular guide rail, and the first guide rail 21 can rotate around the imaging element 11 with the optical waveguide lens 6 as the center, and the space area formed by the rotation of the first guide rail 21 is a spherical area. In this embodiment, the side of the first guide rail 21 and the second guide rail 31 close to the center of the spherical area is the inner side, and the side of the first guide rail 21 and the second guide rail 31 away from the center of the spherical area is the outer side.

[0050] The second guide rail 31 is a semicircular guide rail, and the second guide rail 31 can be located outside the first guide rail 21 or inside the first guide rail 21. The second guide rail 31 can rotate around the rotation axis 12 with the optical waveguide lens 6 as the center. If the second guide rail 31 is located outside the first guide rail 21, the rotation area of ​​the second guide rail 31 is larger than the rotation area of ​​the first guide rail 21; if the second guide rail 31 is located inside the first guide rail 21, the rotation area of ​​the second guide rail 31 is smaller than the rotation area of ​​the first guide rail 21.

[0051] The support member 4 is used to fix the optical waveguide lens 6 at the center of the spherical area. The shooting element 11 and the rotation shaft 12 extend toward the optical waveguide lens 6 located at the center of the spherical area respectively. The rotation shaft 12 is also used to assemble and connect the support member 4 .

[0052] The light source assembly 5 is inserted into the first guide rail 21 and is slidably connected to the first guide rail 21, and is also inserted into the second guide rail 31 and is slidably connected to the second guide rail 31. Rotating the first guide rail 21 can make the first guide rail 21 slide on the second guide rail 31 with the light source assembly 5, or rotating the second guide rail 31 can make the second guide rail 31 slide on the first guide rail 21 with the light source assembly 5.

[0053] Based on the above technical solution, this embodiment rotates the first guide rail 21 or the second guide rail 31 to make the light source assembly 5 slide on the first guide rail 21 or the second guide rail 31, thereby adjusting the spatial position of the light source assembly 5, changing the orientation of the light source assembly 5 relative to the center of the spherical area, simulating the angle of light emitted by the light source assembly 5 to the optical waveguide lens 6 at different positions, so that rainbow patterns are formed on the surface of the optical waveguide lens 6, and the rainbow pattern effect on the surface of the optical waveguide lens 6 is photographed by the shooting element 11, so as to facilitate the rainbow pattern test of the optical waveguide lens 6.

[0054] In one example, the second guide rail 31 is first fixed, and the first guide rail 21 is driven to rotate around the shooting element 11 with the optical waveguide lens 6 as the center, so that the first guide rail 21 slides with the light source assembly 5 on the second guide rail 31 until the light source assembly 5 slides to the first position; then the first guide rail 21 is fixed, and the second guide rail 31 is driven to rotate around the rotation axis 12 with the optical waveguide lens 6 as the center, so that the second guide rail 31 slides with the light source assembly 5 on the first guide rail 21 until the light source assembly 5 slides to the second position, thereby adjusting the first position of the light source assembly 5 relative to the optical waveguide lens 6.

[0055] In one example, the first guide rail 21 is first fixed, and the second guide rail 31 is driven to rotate around the rotation axis 12 with the optical waveguide lens 6 as the center, so that the second guide rail 31 slides on the first guide rail 21 with the light source assembly 5 until the light source assembly 5 slides to the third position; then the second guide rail 31 is fixed, and the first guide rail 21 is driven to rotate around the shooting element 11 with the optical waveguide lens 6 as the center, so that the first guide rail 21 slides on the second guide rail 31 with the light source assembly 5 until the light source assembly 5 slides to the fourth position, thereby adjusting the second position of the light source assembly 5 relative to the optical waveguide lens 6.

[0056] In one example, the first guide rail 21 and the second guide rail 31 are rotated simultaneously to adjust the position of the light source assembly 5 on the first guide rail 21 and the second guide rail 31 , thereby adjusting the third position of the light source assembly 5 relative to the optical waveguide lens 6 .

[0057] In one embodiment, if Figure 2 As shown, the second guide rail 31 is located at a side of the first guide rail 21 away from the support member 4 , and the second guide rail 31 has a preset distance from the first guide rail 21 .

[0058] Specifically, the second guide rail 31 is located outside the first guide rail 21, and the second guide rail 31 and the first guide rail 21 have a preset distance, that is, the second guide rail 31 and the first guide rail 21 have a certain spacing distance, and the two do not contact each other. When the first guide rail 21 rotates around the shooting element 11 with the optical waveguide lens 6 as the center, or when the second guide rail 31 rotates around the rotation axis 12 with the optical waveguide lens 6 as the center, the first guide rail 21 and the second guide rail 31 do not interfere with each other.

[0059] In one embodiment, if Figure 2 As shown, the light source assembly 5 includes a light source 51 and a fixed bracket 52 . The fixed bracket 52 is slidably connected to the first guide rail 21 and the second guide rail 31 . The light source 51 is disposed on the fixed bracket 52 , and the light emitting end of the light source 51 faces the optical waveguide lens 6 .

[0060] Specifically, the light source 51 is a laser, the light output end of the laser faces the optical waveguide lens 6, and the laser can emit parallel light to the optical waveguide lens 6. The fixed bracket 52 is a supporting structure of the light source 51, and by rotating the first guide rail 21 or the second guide rail 31, the fixed bracket 52 slides with the light source 51 on the first guide rail 21 or the second guide rail 31, thereby adjusting the orientation of the light source 51 relative to the optical waveguide lens 6.

[0061] In this embodiment, the light source 51 and the fixing bracket 52 may be fixedly connected or detachably connected, for example, the light source 51 is fixed to the fixing bracket 52 by screws or buckles.

[0062] In one embodiment, if Figures 5 to 7As shown, the fixed bracket 52 includes a fixed sleeve 520, a first limiting plate 521 and a second limiting plate 522. The fixed sleeve 520 is inserted into the first guide rail 21 and the second guide rail 31. The first limiting plate 521 and the second limiting plate 522 are respectively connected to the two ends of the fixed sleeve 520 along the length direction of the fixed sleeve 520, and the light source 51 can be detachably assembled in the fixed sleeve 520; the first limiting plate 521 is located on the side of the first guide rail 21 close to the support member 4 and is slidably connected to the first guide rail 21, and the second limiting plate 522 is located on the side of the second guide rail 31 away from the support member 4 and is slidably connected to the second guide rail 31.

[0063] Specifically, the fixed sleeve 520 is inserted into the first guide rail 21, and the first limiting plate 521 is located on the inner side of the first guide rail 21. The first limiting plate 521 abuts against the first guide rail 21 and is slidably connected to the first guide rail 21. When the second guide rail 31 is driven to rotate, the first limiting plate 521 and the fixed sleeve 520 slide along the first guide rail 21 with the light source 51. The fixed sleeve 520 plays a guiding role, and the first limiting plate 521 plays a sliding role and a limiting role, which enhances the sliding effect of the fixed bracket 52 while preventing the fixed bracket 52 from detaching to the outside of the second guide rail 31.

[0064] The fixed sleeve 520 is also inserted into the second guide rail 31, and the second limiting plate 522 is located on the outside of the second guide rail 31. The second limiting plate 522 abuts against the second guide rail 31 and is slidably connected to the second guide rail 31. When the first guide rail 21 is driven to rotate, the second limiting plate 522 and the fixed sleeve 520 slide along the second guide rail 31 with the light source 51. The fixed sleeve 520 plays a guiding role, and the second limiting plate 522 plays a sliding role and a limiting role, which enhances the sliding effect of the fixed bracket 52 while preventing the fixed bracket 52 from detaching from the inner side of the first guide rail 21.

[0065] In this embodiment, the fixed sleeve 520 can be slidably inserted into the first guide rail 21 and the second guide rail 31 through the joint restriction of the first limiting plate 521 and the second limiting plate 522, so as to realize the sliding function of the fixed sleeve 520 with the light source 51 on the first guide rail 21 and the second guide rail 31.

[0066] The first guide rail 21 and the second guide rail 31 may rotate separately or simultaneously, and this embodiment does not impose any specific limitation thereto.

[0067] In this embodiment, the sliding connection between the first limiting plate 521 and the first guide rail 21 and the sliding connection between the second limiting plate 522 and the second guide rail 31 can be realized by using sliding structures such as sliding rails, sliding blocks, and sliding columns.

[0068] It should be understood that if Figure 7As shown, the relative position relationship between the first limit plate 521 and the second limit plate 522 depends on the spatial position of the fixed bracket 52, and the first limit plate 521 is not always located below the second limit plate 522. When the fixed bracket 52 is located at the top of the optical waveguide lens 6 (or the center of the spherical area), the first limit plate 521 is located below the second limit plate 522; when the fixed bracket 52 slides to the bottom of the optical waveguide lens 6, the first limit plate 521 is located above the second limit plate 522.

[0069] In one embodiment, the first limiting plate 521 and the second limiting plate 522 are detachably assembled on two ends of the fixing sleeve 520 .

[0070] Specifically, the first limiting plate 521 and the second limiting plate 522 are both provided with through holes (not shown in the drawings), one end of the fixed sleeve 520 is inserted through the through hole of the first limiting plate 521 and is interference-fitted with the through hole of the first limiting plate 521, and the other end of the fixed sleeve 520 is inserted through the through hole of the second limiting plate 522 and is interference-fitted with the through hole of the second limiting plate 522, so that the first limiting plate 521 and the second limiting plate 522 are respectively fixed to the two ends of the fixed sleeve 520. Of course, fasteners such as screws can also be used to fix the first limiting plate 521 and the second limiting plate 522 to the two ends of the fixed sleeve 520, which is not specifically limited in this embodiment.

[0071] In one embodiment, if Figure 3 , Figure 4 and Figure 7 As shown, a first slide groove 22 extending along the first guide rail 21 is provided on a side of the first guide rail 21 close to the support member 4, and a first universal wheel 523 is provided on a side of the first limiting plate 521 facing the first guide rail 21, and the first universal wheel 523 is slidably arranged in the first slide groove 22; a second guide rail 31 is provided with a second slide groove 32 extending along the second guide rail 31 on a side of the second limiting plate 522 facing the second guide rail 31, and the second universal wheel 524 is slidably arranged in the second slide groove 32.

[0072] Specifically, a first slide groove 22 is provided on the inner side surface of the first guide rail 21, and the first slide groove 22 extends along the first guide rail 21 to form an arc-shaped groove body that is approximately ring-shaped; a second slide groove 32 is provided on the outer side surface of the second guide rail 31, and the second slide groove 32 extends along the second guide rail 31 to form an arc-shaped groove body that is approximately semicircular.

[0073] The first limit plate 521 is provided with a first universal wheel 523 facing the first guide rail 21, and the first universal wheel 523 is slidably disposed in the first slide groove 22 to achieve a sliding connection between the first limit plate 521 and the first guide rail 21. The second limit plate 522 is provided with a second universal wheel 524 facing the second guide rail 31, and the second universal wheel 524 is slidably disposed in the second slide groove 32 to achieve a sliding connection between the second limit plate 522 and the second guide rail 31. The sliding range of the fixed sleeve 520 with the light source 51 on the first guide rail 21 and the second guide rail 31 is the length range of the first slide groove 22 and the second slide groove 32, respectively.

[0074] In one embodiment, if Figures 3 to 6 As shown, the first limiting plate 521 is provided with first universal wheels 523 on the left and right sides relative to the fixed sleeve 520, and two first sliding grooves 22 are arranged at intervals on the inner side surface of the first guide rail 21. The first universal wheels 523 are slidably arranged in the first sliding grooves 22 one by one to prevent the first limiting plate 521 from being offset or shaking, thereby improving the sliding stability of the first limiting plate 521 on the first guide rail 21, and further improving the control accuracy of the orientation of the light source 51.

[0075] The second limiting plate 522 is provided with second universal wheels 524 on the left and right sides relative to the fixed sleeve 520, and two second slide grooves 32 are provided on the outer side surface of the second guide rail 31 at intervals. The second universal wheels 524 are slidably arranged in the second slide grooves 32 one by one to prevent the second limiting plate 522 from being offset or shaking, thereby improving the sliding stability of the second limiting plate 522 on the second guide rail 31, and further improving the control accuracy of the orientation of the light source 51.

[0076] In this embodiment, the two first universal wheels 523 and the two second universal wheels 524 are used to jointly restrict the fixing bracket 52 from self-rotating, thereby preventing the angle of the light emitting end of the light source 51 from changing randomly during the sliding process.

[0077] In one embodiment, if Figure 2 As shown, the first rotating mechanism 2 includes a first driving assembly 23 , and the first driving assembly 23 is used to drive the first guide rail 21 to rotate around the photographing element 11 .

[0078] Specifically, the first guide rail 21 is driven by the first driving assembly 23, so that the first guide rail 21 can rotate around the imaging element 11 with the optical waveguide lens 6 as the center. The first driving assembly 23 can be driven by a motor, a cylinder, a hydraulic drive or a manual operation mechanism, and the present embodiment does not specifically limit the power form of the first driving assembly 23.
