Description

Technical Field

[0001] This invention relates to the field of optoelectronic device coupling technology, and more specifically, to an automatic coupling device for reflective optoelectronic devices. Background Technology

[0002] With the increasing progress of society, people have higher and higher requirements for communication networks, thus increasing the demand for both the quantity and quality of optical communication products. Therefore, the manufacturing technology of optoelectronic devices has become particularly important. Reflective optical elements typically have a multi-layer system as a reflective coating, consisting of a material with a high real refractive index at the operating wavelength (also called a "spacer") and a material with a low real refractive index at the operating wavelength (also called a "absorbing material"). The absorbers are connected to the spacers to form a stack for application in the optical field.

[0003] According to the description in the patent application CN 117031647 B, "This invention discloses a coupling device for optoelectronic devices, specifically relating to the field of optoelectronic device technology. This invention achieves the overall rotational movement of the device through a rotating component, causing the sliding structure to rotate and contact the arc-shaped seat. At this time, the sliding structure is displaced by the arc surface at the end of the arc-shaped seat, causing the sliding structure to control the rotational movement of the first clamping structure. This allows the first clamping structure to flip and automatically clamp and fix the coupling shell. Simultaneously, the first clamping structure drives the second clamping structure to rotate, allowing the two second clamping structures to automatically clamp and fix the two optical devices. When the threaded transmission structure meshes with the upper arc-shaped toothed rod, the movement of the second clamping structure drives the optical device and the coupling shell to complete the docking assembly, allowing the two optical devices to complete the automatic docking assembly operation simultaneously, enabling the coupling shell and the two optical devices to achieve rapid and efficient assembly."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In this invention, a motor-driven rotating structure rotates the coupling shell and the optical device. The mechanical pressing of rollers and an arc-shaped plate achieves the closing and opening of the clamping mechanism, and the meshing of gears and an arc-shaped rack drives the optical device to move and complete the mounting. However, during long-term, high-frequency operation, the rollers and arc-shaped plate, as directly stressed components, inevitably experience mechanical wear, which reduces the stability of force transmission during the pressing process. Furthermore, when there are slight dimensional differences between the optical device or the coupling shell, the pressing stroke of the rollers and arc-shaped plate cannot be adaptively adjusted, easily leading to clamping that is too loose or too tight. Too loose a clamping position causes the workpiece to wobble or shift during subsequent rotation or mounting, while too tight a clamping position may damage the workpiece surface, ultimately causing clamping alignment deviation and affecting the initial alignment reference between the optical device and the coupling shell. Therefore, we propose an automatic coupling device for reflective optoelectronic devices. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide an automatic coupling device for reflective optoelectronic devices to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic coupling device for a reflective optoelectronic device, comprising: a fixed base, wherein two mounting brackets are fixedly installed on the top of the fixed base; a rotating mechanism, wherein the rotating mechanism is disposed inside the mounting brackets and is used to switch the coupling position; a centering mechanism, wherein the centering mechanism is disposed between the two mounting brackets and is used to clamp or release the optical device; and an embedding mechanism, wherein the embedding mechanism is disposed between the two centering mechanisms and is used to realize the coupling operation between the optical device and the coupling shell.

[0008] Preferably, the rotating mechanism includes: a rotating sleeve, which is rotatably installed inside the mounting frame, the rotating sleeve having a hollow structure, and a rotating frame fixedly installed on the inner side of the rotating sleeve; a fixed rod, which passes through the rotating sleeve and the inner side of the rotating frame, and is rotatably installed on the inner side of the mounting frame, with a fourth gear rotatably installed on the side of the fixed rod near the rotating frame; and third gears meshing with the fourth gear are rotatably installed on both sides of the rotating frame.

[0009] Preferably, the rotating mechanism further includes a motor, which is fixedly mounted on the outside of the mounting bracket. A first gear is fixedly mounted on the output end of the motor, and a second gear that meshes with the first gear is fixedly mounted on the outside of the rotating sleeve.

[0010] Preferably, the centering mechanism includes: a mounting plate, which is fixedly mounted inside the third gear, and a limiting base is fixedly mounted at the bottom of the mounting plate; a first electric push rod, which is fixedly mounted on the top of the limiting base, and a sliding frame is fixedly mounted at the output end of the first electric push rod; and a clamping member, which is disposed inside the sliding frame and is used to clamp the optical device.

[0011] Preferably, the clamping member includes a second electric push rod, the output end of which is fixedly mounted with a rack. The rack is slidably mounted inside a corresponding groove on the inner wall of the sliding frame. A fifth gear that meshes with the rack is rotatably mounted inside the sliding frame. The fifth gear is fixedly mounted to a rotating disk through a rotating shaft. An arc-shaped groove is formed on the surface of the rotating disk. A slide rail is fixedly mounted inside the sliding frame. A movable frame is slidably mounted outside the slide rail. A limit rod is fixedly mounted outside the movable frame and is fitted inside the arc-shaped groove. A guide rod is fixedly mounted inside the sliding frame.

[0012] Preferably, the mounting mechanism includes: a first arc-shaped clamp, which is fixedly installed at the top of the center position of the limiting base; a second arc-shaped clamp, which is rotatably installed on the top of the first arc-shaped clamp; and a ladder-shaped bucket, which is fixedly installed on both sides of the second arc-shaped clamp, and guide grooves are provided at the corresponding positions of the second arc-shaped clamp and the ladder-shaped bucket.

[0013] Preferably, the mounting mechanism further includes a spring, which is fixedly installed on the inner side of the first arc-shaped clamp and the second arc-shaped clamp respectively, and a clamping plate is fixedly installed on the end of the spring away from the first arc-shaped clamp and the second arc-shaped clamp.

[0014] Preferably, the guide rod is positioned by the conical guide surface of the ladder platform to ensure that it enters the guide groove, and after the guide rod enters the guide groove, the second arc-shaped clamp can close with the first arc-shaped clamp.

[0015] Preferably, during the rotation process, the rotation of the fourth gear counteracts the influence of the revolution, so that the limiting base maintains its initial orientation.

[0016] Compared with the prior art, the present invention provides an automatic coupling device for reflective optoelectronic devices, which has the following advantages:

[0017] 1. This invention achieves symmetrical clamping of optical devices through a clamping frame, ensuring uniform force and good centering during clamping. This avoids the clamping offset problem caused by mechanical extrusion in existing technologies. The conical guide surface of the ladder-shaped bucket can correct the position of the guide rod, ensuring its accurate entry into the guide groove and achieving pre-alignment of the optical device with the coupling shell. At the same time, the first and second arc-shaped clamps are connected to the clamping plate by springs, which can buffer the clamping force through spring elasticity. This can adapt to coupling shells of different sizes and avoid damage to the workpiece caused by hard contact, solving the problem of poor clamping adaptability in existing technologies.

[0018] 2. This invention maintains the initial orientation of the limiting base, avoiding the workpiece orientation deviation problem during rotation in existing technologies. This ensures that the optical device and coupling shell maintain the preset alignment direction during installation, improving installation accuracy. The rotating mechanism drives the centering mechanism and installation mechanism to rotate as a whole through the rotating sleeve. After the coupling station switch is completed, the loading position and unloading position are automatically interchanged. Compared with the existing technology that relies on gear reverse meshing for reset, the smoothness of continuous operation is significantly improved. Attached Figure Description

[0028] Example: By Figures 1-8 As shown, this invention provides a technical solution: an automatic coupling device for a reflective optoelectronic device, comprising: a fixed base 1, with two mounting brackets 11 fixedly mounted on the top of the fixed base 1; a rotating mechanism 2, disposed inside the mounting brackets 11, used for switching coupling positions; a centering mechanism 3, disposed between the two mounting brackets 11, used for clamping or releasing the optical device 5; and an embedding mechanism 4, disposed between the two centering mechanisms 3, used for coupling the optical device 5 to the coupling shell 6. The rotating mechanism 2 drives the centering mechanism 3 and the embedding mechanism 4 to rotate as a whole through a rotating sleeve 24. After the coupling position is switched, the loading position and the unloading position are automatically interchanged. This design achieves seamless connection between loading / unloading and coupling operations without the need for an additional reset mechanism, reducing non-productive time consumption. Compared with the prior art's reliance on gear reverse meshing reset, the smoothness of continuous operation is significantly improved.

[0029] Furthermore, by Figure 2 and Figure 3As shown, the rotating mechanism 2 includes: a rotating sleeve 24, which is rotatably mounted inside the mounting frame 11. The rotating sleeve 24 has a hollow structure, and a rotating frame 25 is fixedly mounted inside the rotating sleeve 24; a fixing rod 27, which passes through the inner sides of the rotating sleeve 24 and the rotating frame 25, and is rotatably mounted inside the mounting frame 11. A fourth gear 28 is rotatably mounted on the side of the fixing rod 27 closest to the rotating frame 25; and third gears 26, which mesh with the fourth gear 28, are rotatably mounted on both sides of the rotating frame 25. The rotating mechanism 2 also includes a motor 21, which is fixedly mounted inside the mounting frame 11. On the outside of the mounting bracket 11, a first gear 22 is fixedly installed at the output end of the motor 21, and a second gear 23 that meshes with the first gear 22 is fixedly installed on the outside of the rotating sleeve 24. During the rotation, the rotation of the fourth gear 28 cancels the influence of the revolution, so that the limiting base 32 remains in the initial orientation. This design avoids the problem of workpiece orientation deflection during the rotation process in the prior art, and ensures that the optical device 5 and the coupling shell 6 always maintain the preset alignment direction during installation, thus improving the installation accuracy.

[0030] Furthermore, by Figure 4 and Figure 6As shown, the centering mechanism 3 includes: a mounting plate 31, which is fixedly installed inside the third gear 26, and a limiting base 32 is fixedly installed at the bottom of the mounting plate 31; a first electric push rod 33, which is fixedly installed on the top of the limiting base 32, and a sliding frame 34 is fixedly installed at the output end of the first electric push rod 33; and a clamping member, which is disposed inside the sliding frame 34 and is used to clamp the optical device 5. The clamping member includes a second electric push rod 35, and a rack 36 is fixedly installed at the output end of the second electric push rod 35. The rack 36 is slidably installed inside a corresponding groove on the inner wall of the sliding frame 34. A fifth gear 37 that meshes with the rack 36 is rotatably installed inside the sliding frame 34. The fifth gear 37 passes through the sliding frame 34 via a rotating shaft and is fixedly installed to a rotating disk 38. An arc-shaped groove 381 is provided on the surface of the rotating disk 38. A slide rail 39 is fixedly installed on the inner side of the frame 34, and a movable frame 310 is slidably installed on the outer side of the slide rail 39. A limit rod 3101 is fixedly installed on the outer side of the movable frame 310, and the limit rod 3101 is assembled inside the arc-shaped slide groove 381. A guide rod 311 is fixedly installed on the outer side of the movable frame 310. The guide rod 311 is corrected in position by the conical guide surface of the ladder bucket 45 to ensure that it enters the guide groove 46. When the guide rod 311 enters the guide groove 46, the second arc-shaped clamp 42 can close with the first arc-shaped clamp 41. The rack 36 is driven to slide by the second electric push rod 35, which drives the fifth gear 37 and the rotating disk 38 to rotate. The arc-shaped slide groove 381 of the rotating disk 38 drives the movable frame 310 to slide along the slide rail 39 through the limit rod 3101, so that the clamping frame 3102 can symmetrically clamp the optical device 5. This ensures uniform force and good alignment during the clamping process of the optical device 5, avoiding the clamping offset problem caused by mechanical extrusion in existing technologies.

[0031] Furthermore, by Figure 7 and Figure 8As shown, the mounting mechanism 4 includes: a first arc-shaped clamp 41, which is fixedly installed on the top of the center position of the limiting base 32; a second arc-shaped clamp 42, which is rotatably installed on the top of the first arc-shaped clamp 41; and a tiered tray 45, which is fixedly installed on both sides of the second arc-shaped clamp 42, with guide grooves 46 provided at corresponding positions of the second arc-shaped clamp 42 and the tiered tray 45. The mounting mechanism 4 also includes springs 43, which are fixedly installed on the inner sides of the first arc-shaped clamp 41 and the second arc-shaped clamp 42, with the springs 43 located away from the center of the base. A clamping plate 44 is fixedly installed at one end of the first arc-shaped clamp 41 and the second arc-shaped clamp 42. The conical guide surface of the ladder hopper 45 can correct the position of the guide rod 311 to ensure that it accurately enters the guide groove 46 and realizes the pre-alignment of the optical device 5 and the coupling shell 6. At the same time, the first arc-shaped clamp 41 and the second arc-shaped clamp 42 are connected to the clamping plate 44 by the spring 43. The clamping force can be buffered by the spring 43, which can not only adapt to coupling shells 6 of different sizes, but also avoid damage to the workpiece by hard contact, thus solving the problem of poor clamping adaptability in the prior art.

[0032] In actual operation, when this device is used, the optical device 5 is placed inside the clamping frame 3102, and the second electric push rod 35 is activated. The output end of the second electric push rod 35 pushes the rack 36 to rotate. The rack 36 slides inside the groove opened inside the sliding frame 34, driving the fifth gear 37 that meshes with it to rotate. In turn, the fifth gear 37 drives the rotating disk 38 to rotate. The rotation of the rotating disk 38 drives the limiting rod 3101 fixedly installed on the outside of the moving frame 310 to slide within the arc-shaped groove 381 opened on the surface of the rotating disk 38. In turn, the moving frame 310 slides outside the slide rail 39. Then, the clamping frame 3102 is used to clamp the optical device 5. After the coupling shell 6 is placed inside the clamping plate 44 inside the first arc-shaped clamp 41, the second arc-shaped clamp 42 is flipped. The clamping plate 44 set inside the second arc-shaped clamp 42 and the clamping plate 44 set inside the first arc-shaped clamp 41 are used to abut against the optical device 5.

[0033] The first electric push rod 33 is activated, which pushes the sliding frame 34 to slide inside the limiting base 32. This causes the guide rod 311 to enter the guide groove 46 under the guidance of the ladder hopper 45. Because the first arc-shaped clamp 41 and the bottom clamping plate 44 are fixedly installed by spring 43, and the second arc-shaped clamp 42 and the top clamping plate 44 are also fixedly installed by spring 43, the position of the second arc-shaped clamp 42 will change according to the position of the coupling shell 6. The ladder hopper 45 has a large outer diameter, which allows the guide rod 311 to enter the guide groove 46 under the guidance of the ladder hopper 45 for guiding operation. Then, the second arc-shaped clamp 42 is pressed down, so that the second arc-shaped clamp 42 and the first arc-shaped clamp 41 are closed. At this time, the installation operation of the optical device 5 and the coupling shell 6 is completed.

[0034] When the motor 21 is started, the output end of the motor 21 drives the first gear 22 to rotate. The rotation of the first gear 22 drives the second gear 23, which meshes with it, to rotate. The rotation of the second gear 23 drives the rotating sleeve 24 to rotate. The rotation of the rotating sleeve 24 drives the rotating frame 25 to rotate. The rotation of the rotating frame 25 causes the third gear 26 to rotate outside the fourth gear 28, and the fixing rod 27 on the back of the fourth gear 28 rotates inside the rotating sleeve 24. The fixing rod 27 rotates inside the mounting bracket 11. When the third gear 26 rotates outside the fourth gear 28, the fourth gear 28 rotates accordingly. The third gear 26 rotates relative to the rotating frame 25, so that the position and orientation of the limiting base 32 do not change, making it easy to remove it later.

[0035] After the rotation operation is completed, the optical device 5 and coupling shell 6 that have been fitted together can be removed. At this time, the loading position and the unloading position are interchanged, which facilitates continuous operation.
