Description

Technical Field

[0001] This utility model relates to the field of optical device technology, specifically to an optical device assembly and positioning fixture. Background Technology

[0002] Optical devices are divided into active devices and passive devices. Active optical devices are optoelectronic devices in optical communication systems that require external power to operate and can convert electrical signals into optical signals or vice versa. They are the heart of the optical transmission system. Passive optical devices are optoelectronic devices that do not require external power to operate. When assembling optical devices, they need to be positioned, so an optical device assembly and positioning fixture is required.

[0003] When positioning optical devices, operators often use corresponding optical device assembly and positioning fixtures. Although existing fixtures can achieve the purpose of positioning, they lack a buffer mechanism in actual use, which may damage the optical devices during the clamping and positioning process. Furthermore, they cannot automatically adjust the height and angle of the fixture assembly, which may reduce assembly efficiency and practicality. Utility Model Content

[0004] The purpose of this utility model is to provide an optical device assembly and positioning fixture to solve the problem mentioned in the background art. When operators position optical devices, they often use corresponding optical device assembly and positioning fixtures. Although existing fixtures can achieve the purpose of positioning, they lack a buffer mechanism in actual use, which may damage the optical device during the clamping and positioning process. Furthermore, they cannot automatically adjust the height and angle of the fixture assembly, which may reduce assembly efficiency and practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an optical device assembly and positioning fixture, comprising a top plate and a bottom plate. A sliding groove is formed at the top of the top plate, and a slider is movably installed inside the groove. A push plate is fixedly installed at the bottom of the slider. An mounting plate is fixedly installed at the bottom of the top plate. A pneumatic cylinder is fixedly installed on one side of the mounting plate, and the output end of the pneumatic cylinder passes through the mounting plate and is fixedly connected to one side of the push plate. A movable plate is fixedly installed at the top of the slider. A round rod is movably installed on one side of the movable plate, with one side of the round rod passing through the movable plate and extending to the left side of the movable plate. A clamping plate is fixedly installed on one side of the round rod, and springs are fixedly installed at equal distances between the clamping plate and the movable plate.

[0006] Preferably, a fixing plate is fixedly installed on the top of the top plate, and a buffer pad is fixedly installed on one side of the fixing plate.

[0007] Preferably, a vertical rod is fixedly installed on the top of the base plate, a vertical groove is opened inside the vertical rod, a threaded rod is rotatably installed inside the vertical groove, a threaded sleeve is threaded onto the surface of the threaded rod, and a lifting plate is fixedly installed on one side of the threaded sleeve.

[0008] Preferably, a lifting motor is fixedly installed at the top of the vertical rod, and the output end of the lifting motor passes through the vertical rod and is fixedly connected to the top of the threaded rod.

[0009] Preferably, a connecting plate is fixedly installed on the top of the lifting plate, and vertical plates are fixedly installed on both sides of the top of the connecting plate. A rotating shaft is rotatably installed between the vertical plates. A turntable is fixedly sleeved on the surface of the rotating shaft. A connecting block is fixedly installed on the top of the turntable, and the top of the connecting block is fixedly connected to the bottom of the top plate.

[0010] Preferably, a rotating rod is rotatably mounted between the vertical plates, and a gear is fixedly sleeved on the surface of the rotating rod. The outer surface of the gear meshes with the outer surface of the turntable. A rotary motor is fixedly mounted on one side of the vertical plate, and the output end of the rotary motor passes through the vertical plate and is fixedly connected to one side of the rotating rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This optical device assembly and positioning fixture, during daily use, involves the operator placing the optical device on top of the top plate and one side of the buffer pad. The pneumatic cylinder is then activated, causing the push plate to slide. The push plate then moves the slider within the slide groove, which in turn moves the moving plate. The moving plate then moves the clamping plate until one side of the clamping plate reaches the other side of the optical device. At this point, the clamping plate moves the round rod within the moving plate, compressing the spring. This, along with the spring and buffer pad, buffers the clamping force during positioning, reducing damage to the optical device.

[0012] This optical device assembly and positioning fixture, during daily use, involves the operator activating a lifting motor. The motor's operation causes a threaded rod to rotate, which in turn causes a threaded sleeve to slide within a vertical groove. This threaded sleeve then causes a lifting plate to slide, which in turn causes a connecting plate to slide, ultimately leading to the top plate and the optical device on top of it sliding. This allows for automatic adjustment of the assembly height. Simultaneously, activating a rotary motor causes a rotating rod to rotate, which in turn causes a gear to rotate. The gear then causes a turntable to rotate, which in turn causes a rotating shaft to rotate between the vertical plates. Subsequently, the turntable causes a connecting block to rotate, which in turn causes the top plate to rotate, thus rotating the top plate and the optical device on top of it. This allows for automatic adjustment of the assembly tilt angle. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0016] Please see Figures 1-5 A positioning fixture for assembling optical devices includes a top plate 1 and a bottom plate 13. A groove 2 is provided on the top of the top plate 1, and a slider 3 is movably installed inside the groove 2. A push plate 4 is fixedly installed at the bottom of the slider 3. An mounting plate 5 is fixedly installed at the bottom of the top plate 1. A pneumatic cylinder 6 is fixedly installed on one side of the mounting plate 5. The output end of the pneumatic cylinder 6 passes through the mounting plate 5 and is fixedly connected to one side of the push plate 4. A movable plate 7 is fixedly installed on the top of the slider 3. A round rod 8 is movably installed on one side of the movable plate 7. One side of the round rod 8 passes through the movable plate 7 and extends to the left side of the movable plate 7. A clamping plate 9 is fixedly installed on one side of the round rod 8, and springs 10 are fixedly installed at equal distances between the clamping plate 9 and the movable plate 7. A fixing plate 11 is fixedly installed on the top of the top plate 1, and a buffer pad 12 is fixedly installed on one side of the fixing plate 11.

[0017] In this invention, when positioning the optical device is required, the optical device is placed on top of the top plate 1 and on one side of the buffer pad 12. Then, the pneumatic cylinder 6 is activated. The operation of the pneumatic cylinder 6 will push the push plate 4 to slide. Subsequently, the push plate 4 will drive the slider 3 to slide inside the slide groove 2. The inner surface of the slide groove 2 and the outer surface of the slider 3 are both smooth, which allows the slider 3 to slide more smoothly inside the slide groove 2 and reduces the occurrence of jamming. Due to the design of the slide groove 2 and the slider 3, the sliding of the moving plate 7 is more stable. At the same time, the slider 3 will drive the moving plate 7 to slide. Subsequently, the moving plate 7 will drive the clamping plate 9 to slide until one side of the clamping plate 9 reaches the other side of the optical device. At this time, the clamping plate 9 will drive the round rod 8 to slide inside the moving plate 7. Subsequently, the clamping plate 9 will squeeze and compress the spring 10, which can position the optical device. The clamping force during positioning is buffered by the spring 10 and the buffer pad 12, reducing the damage to the optical device. Example 2:

[0018] Please see Figures 1-5 A positioning fixture for assembling optical devices includes a vertical rod 14 fixedly mounted on the top of a base plate 13. The vertical rod 14 has a vertical groove 15 inside, and a threaded rod 16 is rotatably mounted inside the vertical groove 15. A threaded sleeve 17 is threaded onto the surface of the threaded rod 16, and a lifting plate 18 is fixedly mounted on one side of the threaded sleeve 17. A lifting motor 19 is fixedly mounted on the top of the vertical rod 14, and the output end of the lifting motor 19 passes through the vertical rod 14 and is fixedly connected to the top of the threaded rod 16.

[0019] In this invention, when the assembly height of the optical device needs to be adjusted, the lifting motor 19 is started. The operation of the lifting motor 19 will cause the threaded rod 16 to rotate, and the threaded rod 16 will drive the threaded sleeve 17 to slide inside the vertical groove 15. At this time, the threaded sleeve 17 will drive the lifting plate 18 to slide, and the lifting plate 18 will drive the connecting plate 20 to slide, thereby driving the top plate 1 and the optical device on its top to slide, so that the assembly height can be automatically adjusted. Example 3:

[0020] Please see Figures 1-5A positioning fixture for assembling optical devices is provided. A connecting plate 20 is fixedly installed on the top of a lifting plate 18. Vertical plates 21 are fixedly installed on both sides of the top of the connecting plate 20. A rotating shaft 22 is rotatably installed between the vertical plates 21. A turntable 23 is fixedly sleeved on the surface of the rotating shaft 22. A connecting block 24 is fixedly installed on the top of the turntable 23, and the top of the connecting block 24 is fixedly connected to the bottom of the top plate 1. A rotating rod 25 is rotatably installed between the vertical plates 21. A gear 26 is fixedly sleeved on the surface of the rotating rod 25. The outer surface of the gear 26 meshes with the outer surface of the turntable 23. A rotary motor 27 is fixedly installed on one side of the vertical plate 21, and the output end of the rotary motor 27 passes through the vertical plate 21 and is fixedly connected to one side of the rotating rod 25.

[0021] In this invention, when the assembly tilt angle of the optical device needs to be adjusted, the rotary motor 27 is started. The operation of the rotary motor 27 causes the rotating rod 25 to rotate, which in turn drives the gear 26 to rotate. Subsequently, the gear 26 drives the turntable 23 to rotate, which in turn drives the rotating shaft 22 to rotate between the vertical plates 21. Then, the turntable 23 drives the connecting block 24 to rotate, which in turn drives the top plate 1 to rotate. This causes the top plate 1 and the optical device on its top to rotate, thus automatically adjusting the assembly tilt angle.

[0022] Working principle: First, the operator places the optical device on top of the top plate 1 and one side of the buffer pad 12. Then, the pneumatic cylinder 6 is activated. The operation of the pneumatic cylinder 6 pushes the push plate 4 to slide. Subsequently, the push plate 4 drives the slider 3 to slide inside the slide groove 2. At the same time, the slider 3 drives the moving plate 7 to slide. The moving plate 7 then drives the clamping plate 9 to slide until one side of the clamping plate 9 reaches the other side of the optical device. At this time, the clamping plate 9 drives the round rod 8 to slide inside the moving plate 7. Then, the clamping plate 9 squeezes and compresses the spring 10, thus positioning the optical device. Next, the lifting motor 19 is activated. The operation of the lifting motor 19 causes the threaded rod 16 to rotate. Subsequently, the threaded rod 16 drives the threaded sleeve 17 in the vertical groove 15. When internal sliding occurs, the threaded sleeve 17 will cause the lifting plate 18 to slide, which in turn will cause the connecting plate 20 to slide, and then cause the top plate 1 and its top optical components to slide, thus automatically adjusting the assembly height. At the same time, the rotary motor 27 is started, and the operation of the rotary motor 27 will cause the rotating rod 25 to rotate, which in turn will cause the gear 26 to rotate. Subsequently, the gear 26 will cause the turntable 23 to rotate, which in turn will cause the rotating shaft 22 to rotate between the vertical plates 21. Then the turntable 23 will cause the connecting block 24 to rotate, which in turn will cause the top plate 1 to rotate, thus causing the top plate 1 and its top optical components to rotate, thus automatically adjusting the assembly tilt angle.
