Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical communication technology, and in particular to a fast positioning fixture for synchronous coupling of dual lenses in an optical module. Background Technology
[0002] Against the backdrop of the rapid development of optical communication technology, the performance optimization of optical modules has become a key research area. Lens coupling operation in optical modules is of vital importance to ensuring the efficient transmission of optical signals.
[0003] In traditional optical module lens coupling fixtures, the lens is often fixed by a conventional clamp during operation. In this way, the clamp is in direct contact with the lens surface. Since lenses are usually quite fragile, the clamp is very likely to damage the lens surface during the clamping process. This damage not only affects the optical performance of the lens, but may also lead to a decrease in the performance of the entire optical module, increasing production costs and product defect rate. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a fast positioning fixture for synchronous coupling of dual lenses in optical modules.
[0005] This utility model is achieved using the following technical solution: a fast positioning fixture for synchronous coupling of dual lenses in an optical module, comprising a positioning platform, a limiting groove formed on the upper surface of the positioning platform, a mounting sleeve slidably connected to one side of the limiting groove, a groove plate 1 fixedly connected to the surface of the mounting sleeve 1, a mounting sleeve 2 slidably connected to the other side of the limiting groove, a groove plate 2 fixedly connected to the surface of the mounting sleeve 2, a protective shell slidably connected inside the groove plate 1, a vacuum pump housed inside the protective shell, a lens body fixedly connected to the input end of the vacuum pump, a lead screw 1 threadedly connected inside the protective shell, a first handle fixedly connected to the surface of the lead screw 1, a drive motor fixedly connected to the inner wall of the limiting groove, and a positive and negative threaded screw fixedly connected to the output end of the drive motor, the positive and negative threaded screws being threadedly connected inside the mounting sleeve 1 and the mounting sleeve 2.
[0006] The above technical solution avoids damage to the lens body due to clamping, and enables rapid initial adjustment and further precise adjustment of the position of the lens body and the optical module.
[0007] As a further improvement to the above solution, a positioning sleeve is slidably connected inside the second slide plate, and a rod is inserted into the positioning sleeve.
[0008] As a further improvement to the above solution, a frame is fixedly connected to the surface of the plug, and an optical module body is disposed inside the frame.
[0009] As a further improvement to the above solution, the positioning sleeve is internally threaded with a second lead screw, and a second handle is fixedly connected to the surface of the second lead screw.
[0010] The above technical solution can precisely adjust the position of the optical module body and improve the accuracy of coupling between the optical module body and the lens body.
[0011] As a further improvement to the above solution, the first handle and the second handle have several holes inside, and a locking rod is inserted into the holes.
[0012] The above technical solutions ensure the positional stability of the lens body and the optical module body, and improve the accuracy and reliability of the entire coupling process.
[0013] As a further improvement to the above solution, a connecting sleeve is fixedly connected to the upper surface of the positioning stage, and a magnetic sheet is fixedly connected to the inner wall of the connecting sleeve.
[0014] As a further improvement to the above solution, the locking rod is in contact with the magnetic sheet.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention uses the suction force generated by a vacuum pump to fix the lens, thereby stabilizing the lens body and avoiding surface damage that might be caused by clamping, thus protecting the integrity of the lens body. After adjustment, the operator inserts a locking rod into the holes of the first and second handles and into contact with the magnetic sheet. The magnetic sheet's adsorption force locks the handle position. Through the interaction between the locking rod and the magnetic sheet, the positions of the first and second handles are locked, preventing rotation due to external forces. This prevents movement of the lens body and the optical module body, ensuring the stability of their relative positions and contributing to improved quality and stability of the synchronous coupling of the dual lenses in the optical module.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0025] Example:
[0026] Please combine Figure 1-5 This embodiment of a fast positioning fixture for synchronous coupling of dual lenses in an optical module includes a positioning stage 1. A limiting groove 2 is formed on the upper surface of the positioning stage 1. A mounting sleeve 3 is slidably connected to one side of the limiting groove 2. A sliding plate 4 is fixedly connected to the surface of the mounting sleeve 3. A mounting sleeve 5 is slidably connected to the other side of the limiting groove 2. A sliding plate 6 is fixedly connected to the surface of the mounting sleeve 5. A protective shell 7 is slidably connected inside the sliding plate 4. A vacuum pump 8 is installed inside the protective shell 7. A lens body 9 is fixedly connected to the input end of the vacuum pump 8. A lead screw 10 is threadedly connected inside the protective shell 7. A first handle 11 is fixedly connected to the surface of the lead screw 10. A drive motor 12 is fixedly connected to the inner wall of the limiting groove 2. A positive and negative threaded screw 13 is fixedly connected to the output end of the drive motor 12. The positive and negative threaded screw 13 is threadedly connected to the inside of the mounting sleeve 3 and the mounting sleeve 5. The lens body 9 is adsorbed and fixed by the vacuum pump 8. This fixing method avoids the surface damage to the lens body 9 that may be caused by the fixture directly clamping it. Then, the drive motor 12 drives the positive and negative threaded rods 13 to rotate. Since the positive and negative threaded rods 13 are threadedly connected to the mounting sleeve 3 and the mounting sleeve 5 respectively, and the mounting sleeve 3 and the mounting sleeve 5 are located on both sides of the limiting slide groove 2, when the positive and negative threaded rods 13 rotate, the mounting sleeve 3 and the mounting sleeve 5 can move synchronously to the center or to the sides, thereby initially adjusting the position of the lens body 9 and the optical module. Finally, the operator rotates the first handle 11, which drives the lead screw 10 to rotate. The lead screw 10 is threadedly connected to the protective shell 7, and the protective shell 7 slides within the slide plate 4, thereby further adjusting the position of the lens body 9.
[0027] The sliding connection inside the slide plate 26 is a positioning sleeve 14, and the positioning sleeve 14 is inserted with a rod 15.
[0028] A frame 16 is fixedly connected to the surface of the insertion rod 15. The optical module body 17 is set inside the frame 16. The optical module body 17 is placed inside the frame 16. The frame 16 is connected to the positioning sleeve 14 through the insertion rod 15. With the help of the sliding characteristics of the positioning sleeve 14 in the slide plate 6, the position of the optical module body 17 can be adjusted within a certain range, which facilitates coupling with the lens body 9.
[0029] The positioning sleeve 14 is internally threaded with a lead screw 18, and a second handle 19 is fixedly connected to the surface of the lead screw 18. Rotating the second handle 19 causes the lead screw 18 to rotate. The lead screw 18 is threadedly connected to the positioning sleeve 14, thereby allowing the positioning sleeve 14 to slide within the slide plate 6. Since the positioning sleeve 14 is connected to the insertion rod 15, and the insertion rod 15 is connected to the frame 16, and the frame 16 contains the optical module body 17, the position of the optical module body 17 can be adjusted.
[0030] The first handle 11 and the second handle 19 have several holes inside, and a locking rod 20 is inserted into the hole. When the locking rod 20 is inserted into the hole of the first handle 11 and the second handle 19, and the locking rod 20 contacts the magnetic sheet 22, the magnetic sheet 22's adsorption or friction force is used to prevent the locking rod 20 from moving easily, thereby locking the position of the first handle 11 and the second handle 19, preventing the handle from rotating due to external force, and thus preventing the lens body 9 and the optical module body 17 from moving.
[0031] A connecting sleeve 21 is fixedly connected to the upper surface of the positioning stage 1, and a magnetic sheet 22 is fixedly connected to the inner wall of the connecting sleeve 21.
[0032] The locking rod 20 is in contact with the magnetic plate 22.
[0033] The implementation principle of the optical module dual-lens synchronous coupling quick-adjustment fixture in this embodiment is as follows: First, the operator turns on the vacuum pump 8 inside the protective shell 7. The input end of the vacuum pump 8 is fixedly connected to the lens body 9. The suction force generated by the vacuum pump 8 is used to adsorb and fix the lens body 9. The purpose of this is to avoid using a fixture to directly clamp the lens body 9 and prevent the surface of the lens body 9 from being damaged by the fixture. The operator then starts the drive motor 12 fixedly connected to the inner wall of the limiting slide 2. The output end of the drive motor 12 is connected to the positive and negative threaded rods 13. Since the positive and negative threaded rods 13 are respectively threaded to the mounting sleeve 3 and mounting sleeve 5 located on both sides of the limiting slide 2, when the drive motor 12 drives the positive and negative threaded rods 13 to rotate, the mounting sleeve 3 and mounting sleeve 5 will move synchronously to the center or both sides. The operator manually rotates the first handle 11. The first handle 11 is fixed to the surface of the threaded rod 10. The threaded rod 10 is threadedly connected to the protective shell 7. When the first handle 11 is rotated, the threaded rod 10 rotates accordingly, causing the protective shell 7 to slide inside the slide plate 4, thereby driving the lens body 9 to rotate. The lens body 9 is further positioned, and the optical module body 17 is placed inside the frame 16. The frame 16 is inserted into the positioning sleeve 14 through the plug rod 15 fixedly connected to its surface. Then, the operator rotates the second handle 19, which is fixed to the surface of the second lead screw 18. The second lead screw 18 is threadedly connected to the positioning sleeve 14. When the second handle 19 is rotated, the second lead screw 18 rotates, causing the positioning sleeve 14 to slide in the slide plate 6. Since the positioning sleeve 14 is connected to the plug rod 15, and the plug rod 15 is connected to the frame 16, and the optical module body 17 is inside the frame 16, the position of the optical module body 17 can be precisely adjusted. Finally, the locking rod 20 is inserted into the holes opened inside the first handle 11 and the second handle 19, so that the locking rod 20 contacts the magnetic sheet 22 fixedly connected to the inner wall of the connecting sleeve 21. The magnetic sheet 22's adsorption or friction prevents the locking rod 20 from moving easily, thereby locking the positions of the first handle 11 and the second handle 19 and preventing the handles from rotating due to external force, thus preventing the lens body 9 and the optical module body 17 from moving.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
