Description

Technical Field

[0001] The present invention relates to the technical field of optical device processing, and in particular to an optical device coupling device. Background Art

[0002] Optical device coupling refers to the docking between optical devices, aiming to achieve efficient optical signal transmission while minimizing light loss efficiency. This coupling process involves precise adjustment of the spatial position of the optical device, and fine adjustment using a coupling table to ensure that the uniformity and consistency of light are in the best state. The coupling of optical devices mainly relies on photosensitive glue curing technology. The principle of photosensitive glue curing technology mainly relies on the photoinitiator in the photosensitive resin to produce active free radicals or cations under ultraviolet light, thereby initiating monomer polymerization and cross-linking chemical reactions, so that the adhesive changes from liquid to solid in a very short time. This process not only has a fast curing speed, but also has a controllable reaction, is suitable for automated operation, and is solvent-free, so it is pollution-free. During the coupling process, the device and optical fiber to be coupled are placed on the coupling table for automated processing, and the overall intelligence and automation level are high.

[0003] However, in the actual processing process, the installation operation of the optical fiber is mainly completed manually. Although the optical fiber is relatively thin, it is heavy. It is time-consuming and laborious to control the movement of the optical fiber and the glass raw material manually. In addition, during the coupling operation, it is also necessary to manually detect the connection effect of the optical fiber and the glass raw material. In this process, it is also necessary to manually remove the solidified glue that may remain on the side wall of the glass raw material, which further increases the workload of the workers. Therefore, an optical device coupling device is provided. Summary of the invention

During this process, it can be observed whether the rotating drum rotates. If the rotating drum does not rotate, it means that the connection between the optical fiber and the glass raw material is good.

[0026] During the up and down movement of the cleaning plate, the sensor is activated and sends out a corresponding electrical signal. During the up and down movement of the cleaning plate, if the electrical signal is always in a constant state and does not change, it means that there is no glue on the side wall of the glass raw material or the glue has been cleaned; if the electrical signal is always in a changing state, it means that there is glue on the side wall of the glass raw material, thereby completing the self-inspection operation on the side wall of the glass raw material.

The clamping plate 205 and the positioning plate 201 are slidably connected, and the clamping plate 205 is located on the front side of the fixing block 4;

[0047] During the coupling process of the optical device, the glass raw material 6 is placed on the upper side of the positioning plate 201, and then the PIN needle 10 is inserted into the opening 5. The first threaded rod 202 is rotated, and the first threaded rod 202 drives the clamping plate 205 to move through the threaded plate 203 and the first connecting rod 204 until the clamping plates 205 on both sides and the glass raw material 6 are against each other, thereby completing the clamping and fixing operation of the glass raw material 6, and then the corresponding processing operation can be started.

[0048] like Figure 4 , Figure 5 , Figure 6 , Figure 7A moving assembly 3 is fixedly installed on the upper side of the workbench 1. The moving assembly 3 includes a mounting plate 301, a motor 302, a rotating cylinder 306, and a fourth connecting plate 315. The mounting plate 301 is fixedly installed on the upper side of the workbench 1, and the motor 302 is fixedly installed on the inner side of the mounting plate 301. The output end of the motor 302 is fixedly connected with a rotating shaft. The fourth connecting plate 315 is located on the upper side of the mounting plate 301 and is slidably connected to the mounting plate 301. There are multiple fourth connecting plates 315. Two groups of rotating rods 305 are rotatably connected to the upper side of each fourth connecting plate 315. Multiple groups of rotating rods 305 rotate and penetrate the fourth connecting plate 315. A transmission rod 311 is fixedly connected to the lower side of one of the rotating rods 305 in each group of rotating rods 305. A pulley assembly 303 is sleeved between the transmission rod 311 and the rotating shaft. A sliding groove 314 is opened on the upper side of the mounting plate 301, and multiple groups of slide plates 317 are slidably connected in the sliding groove 314. The inside of the slide plate 317 is fixedly connected with a third connecting rod 316, and the third connecting rod 316 is fixedly connected to the fourth connecting plate 315. The outer side of the rotating cylinder 306 is roughly set. The moving component 3 also includes a second connecting rod 310. The number of the second connecting rods 310 is multiple groups. The second connecting rods 310 and the third connecting rods 316 are staggered, and the same second connecting plate 309 is rotatably connected between each adjacent second connecting rod 310 and third connecting rod 316. The first connecting plate 304 is fixedly connected to both sides of the mounting plate 301. The side wall of the first connecting plate 304 is threadedly sleeved with a second threaded rod 308. One end of the second threaded rod 308 is rotatably connected to the third connecting plate 312. The third connecting plate 312 is slidably connected to the first connecting plate 304. The side wall of the third connecting plate 312 is fixedly connected with a sleeve plate 313, and the sleeve plate 313 is rotatably sleeved on the outer side of one of the second connecting rods 310.

[0049] First, the pulley assembly 303 includes a belt, a pulley, a tensioner, etc. During the movement of the transmission rod 311, after starting the motor 302, the transmission rod 311 can be driven to rotate through the rotating shaft. This is a prior art and no unnecessary details are given. Secondly, the second connecting rod 310 located in the middle is fixedly connected to the mounting plate 301. Before the processing operation is performed, the second threaded rod 308 is rotated, and the second threaded rod 308 drives the sleeve plate 313 to move through the third connecting plate 312. The sleeve plate 313 drives the second connecting rod 310 to move. Under the action of the second connecting plate 309, the moving second connecting rod 310 drives the second connecting plate 309 to rotate around the third connecting rod 316, so that The distance between two adjacent third connecting rods 316 increases or decreases, and the third connecting rod 316 drives the fourth connecting plate 315 to move, thereby expanding or reducing the distance between adjacent fourth connecting plates 315. The fourth connecting plate 315 drives the rotating cylinder 306 to move through the rotating rod 305 until the distance between adjacent rotating cylinders 306 meets the working needs. The optical fiber 9 is inserted between two adjacent rotating cylinders 306, and the motor 302 is started. The motor 302 drives the transmission rod 311 to rotate through the pulley assembly 303. The transmission rod 311 drives the rotating cylinder 306 to rotate through the rotating rod 305. The rotating cylinder 306 drives the optical fiber 9 to move, so that the optical fiber 9 moves into the V-groove 7, and the corresponding coupling operation begins.

[0050] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12, a detection assembly is installed in the rotating cylinder 306, and the detection assembly includes a fixed cylinder 319, a connecting ring 320, a regulating ring 322, a fourth connecting rod 324, a fixed plate 325, a fifth connecting plate 326, and a sixth connecting plate 330. The fixed cylinder 319 is fixedly sleeved on the outer side of the rotating rod 305, the connecting ring 320 is rotatably sleeved on the outer side of the fixed cylinder 319, the connecting ring 320 is fixedly sleeved on the inner side of the rotating cylinder 306, and the number of the regulating ring 322 is two groups, and the two groups of regulating rings 322 are symmetrically arranged on both sides of the connecting ring 320, and the regulating ring 322 is slidably sleeved on the outer side of the fixed cylinder 319, and two groups of clamping rings 321 are fixedly sleeved on the outer side of the fixed cylinder 319, and the clamping ring 321 is located on the outer side of the regulating ring 322, and a first spring 323 is fixedly connected between the clamping ring 321 and the regulating ring 322, and the fourth connecting rod 324 is fixedly mounted on the outer side of the regulating ring 322 The second spring 327 is fixedly connected to the fifth connecting plate 326 and the fixing plate 325, and the fixing plate 325 is fixedly connected to the fifth connecting plate 326 and the fixing plate 325. The fixing plates 325 are symmetrically arranged on both sides of the connecting ring 320, and the fixing plates 326 are circumferentially slidably installed on the inner side of the rotating cylinder 306. The fifth connecting plate 326 and the fixing plate 325 are staggered. A second spring 327 is fixedly connected between the fifth connecting plate 326 and one of the adjacent fixing plates 325. A plurality of groups of inclined grooves 328 are circumferentially opened in the rotating cylinder 306, and a sliding rod 329 is slidably connected in each inclined groove 328. The sixth connecting plate 330 is fixedly connected to the sliding rod 329, and the sliding rod 329 and the fifth connecting plate 326 are abutted against each other. The sixth connecting plate 330 is located on the outer side of the regulating ring 322.

[0051] After the optical fiber 9 is installed, the motor 302 is started again, so that the motor 302 drives the rotating rod 305 and the rotating cylinder 306 to rotate in the opposite direction of the previous rotation direction through the pulley assembly 303 and the transmission rod 311, so that the optical fiber 9 and the glass material 6 are moved as a whole in the direction away from the fixed block 4. When the glass material 6 is about to collide with the rotating cylinder 306, the rotating cylinder 306 will be stuck. Since the rotating cylinder 306 is roughly designed, the rotating cylinder 306 stops rotating under the obstruction of the optical fiber 9, but the rotating rod 305 still rotates. The rotating rod 305 rotates at the same time and drives the regulating ring 322 and the fourth connecting rod 324 to rotate around the rotating rod 305, the fourth connecting rod 324 and the fifth connecting plate 326 abut against each other and drive the fifth connecting plate 326 to move, the fifth connecting plate 326 compresses the second spring 327, and at the same time, the fifth connecting plate 326 also drives the sliding rod 329 and the sixth connecting plate 330 to move, and under the restriction of the inclined groove 328, the sixth connecting plate 330 and the sliding rod 329 will not only move with the fifth connecting plate 326, but also move upward relative to the fifth connecting plate 326 (by Fig.11In the process of the sixth connecting plate 330 moving upward, the sixth connecting plates 330 on the upper and lower sides are symmetrically arranged. Fig. 9 The sixth connecting plate 339 on the upper side and the regulating ring 332 abut against each other and drive the regulating ring 332 to move downward, and the sixth connecting plate 330 on the lower side and the regulating ring 322 abut against each other and drive the regulating ring 322 to move upward. In this process, the movement direction of the sixth connecting plate 330 has the same effect, so the movement of the sixth connecting plate 330 on the lower side is explained. While the regulating ring 322 stretches the first spring 323, it drives the fourth connecting rod 324 to move upward until the fourth connecting rod 324 and the fifth connecting plate 326 are disconnected. At this time, under the action of the second spring 327, the fifth connecting plate 326 returns to its original position. Under the action of the adjusting ring 322, the adjusting ring 322 returns to the original position relative to the rotating rod 305, so that when the rotating cylinder 306 stops moving, a force is applied to the rotating cylinder 306. Since the rotating cylinder 306 and the optical fiber 9 are against each other, an operation of stretching the optical fiber 9 relative to the glass raw material 6 is formed. During this process, it can be observed whether the rotating cylinder 306 rotates. If the rotating cylinder 306 does not rotate, it means that the connection between the optical fiber 9 and the glass raw material 6 is good. If the rotating cylinder 306 rotates, it means that there is looseness between the optical fiber 9 and the glass raw material 6, and the connection between the optical fiber 9 and the glass raw material 6 is poor, and corresponding adjustments need to be made.

[0052] like Fig.13 , Fig.14 A cleaning assembly is installed on the outer side of the rotating cylinder 306, and the cleaning assembly includes a moving ring 318, a positioning ring 332, and a cleaning plate 334. There are two groups of moving rings 318, and the two groups of moving rings 318 are symmetrically arranged on the outer sides of the rotating cylinder 306, and the moving rings 318 are sleeved on the outer side of the rotating rod 305. The moving ring 318 is fixedly connected by the fifth connecting rod 331 and the sixth connecting plate 330, and the positioning ring 332 is rotatably sleeved on the outer side of the moving ring 318. A through groove is opened on the outer side of the positioning ring 332, and a sixth connecting rod 333 is slidably connected in the through groove. The cleaning plate 334 and the sixth connecting rod 333 are fixedly connected;

[0053] In the process of the rotating cylinder 306 driving the optical fiber 9 and the glass raw material 6 to move, when the glass raw material 6 and the cleaning plate 334 are in contact with each other, the glass raw material 6 will be stuck. When the rotating cylinder 306 stops rotating, the sixth connecting plate 330 will move up and down. The sixth connecting plate 330 drives the moving ring 318 to move up and down through the fifth connecting rod 331. The moving ring 318 drives the regulating ring 322 to move up and down. The regulating ring 322 drives the cleaning plate 334 to move up and down through the sixth connecting rod 333. The cleaning plate 334 is always in contact with the side wall of the glass raw material 6, thereby forming a cleaning operation on the side wall of the glass raw material 6, cleaning the glue that may exist on the side wall of the glass raw material 6, and maintaining the cleanliness of the glass raw material 6.

[0054] A sensor 335 is fixedly connected between the sixth connecting rod 333 and the through groove. When the cleaning plate 334 moves up and down, the sensor 335 is activated and sends out a corresponding electrical signal. When the cleaning plate 334 moves up and down, if the electrical signal is always in a constant state and does not change, it means that there is no glue on the side wall of the glass raw material 6 or the glue has been cleaned; if the electrical signal is always in a changing state, it means that there is glue on the side wall of the glass raw material 6.

[0055] A method for processing an optical device coupling device comprises the following steps:

[0056] S1. Simulate the V-groove specifications of the optical fiber and the PIN 10 specifications on the software, and generate the design drawings by the software;

[0058] S3, put the optical fiber 9 into the V-shaped groove 7, then press the optical fiber 9 with the cover plate 8, and put the PIN needle 10 into the V-shaped groove 7, as shown in FIG. Fig.16 ;

[0059] S4, apply UV glue and solidify;

[0060] S5, the angle of the end face of the ground glass MT, the angle range is 90±0.3°;

[0061] S6. Couple the standard MT with the glass MT. When the insertion loss is within 0.5dB, apply glue, fix it, and then remove the product.

[0062] S7, insertion loss test;

[0063] S8. Inspect the appearance.

[0064] In the present invention, when it is necessary to perform coupling operation on the optical device, the specific operation is as follows: simulate the optical fiber V-groove specifications and the PIN needle 10 specifications on the software, generate a design drawing by the software, process the V-groove 7 on the glass raw material 6, after the processing is completed, detect the size of the V-groove 7, insert the PIN needle 10 into the opening 5, rotate the first threaded rod 202, the first threaded rod 202 drives the clamping plate 205 to move through the threaded plate 203 and the first connecting rod 204, until the clamping plates 205 on both sides and the glass raw material 6 are against each other, thereby completing the clamping and fixing operation of the glass raw material 6, start the motor 302, the motor 302 drives the transmission rod 311 to rotate through the pulley assembly 303, the transmission rod 311 drives the rotating cylinder 306 to rotate through the rotating rod 305, the rotating cylinder 306 drives the optical fiber 9 to move, so that the optical fiber 9 moves into the V-groove 7, the optical fiber 9 is pressed by the cover plate 8, UV glue is applied, and it is cured by ultraviolet irradiation. After the curing operation is completed, the motor 302 is started again, so that the motor 302 is driven by the pulley assembly 3 03 and the transmission rod 311 drive the rotating rod 305 and the rotating cylinder 306 to rotate in the opposite direction of the previous rotation direction, thereby causing the optical fiber 9 and the glass raw material 6 to move as a whole in the direction away from the fixed block 4. When the glass raw material 6 and the cleaning plate 334 abut against each other, the glass raw material 6 will be stuck. Since the rotating cylinder 306 is roughly designed, the rotating cylinder 306 stops rotating under the obstruction of the optical fiber 9, but the rotating rod 305 still rotates. Therefore, the rotating rotating rod 305 at this time drives the regulating ring 322 and the fourth connecting rod 324 to rotate around the rotating rod 305 as the center. The fourth connecting rod 324 and the fifth connecting plate 326 abut against each other and drive the fifth connecting plate 326 to move. The fifth connecting plate 326 compresses the second spring 327. At the same time, the fifth connecting plate 326 also drives the sliding rod 329 and the sixth connecting plate 330 to move. Under the limiting effect of the inclined groove 328, the sixth connecting plate 330 and the sliding rod 329 will not only move with the fifth connecting plate 326, but also move upward relative to the fifth connecting plate 326 (with a displacement of 0.05). Fig.11 The sixth connecting plates 330 on the upper and lower sides are symmetrically arranged. Fig. 9The sixth connecting plate 339 on the upper side and the regulating ring 332 abut against each other and drive the regulating ring 332 to move downward, and the sixth connecting plate 330 on the lower side and the regulating ring 322 abut against each other and drive the regulating ring 322 to move upward. In this process, the movement direction of the sixth connecting plate 330 has the same effect, so the movement of the sixth connecting plate 330 on the lower side is explained. While the regulating ring 322 stretches the first spring 323, it drives the fourth connecting rod 324 to move upward until the fourth connecting rod 324 and the fifth connecting plate 326 are disconnected. At this time, under the action of the second spring 327, the fifth connecting plate 326 returns to its original position. Under the condition that the adjusting ring 322 returns to the original position relative to the rotating rod 305, a force is applied to the rotating cylinder 306 when the rotating cylinder 306 stops moving. Since the rotating cylinder 306 and the optical fiber 9 are against each other, an operation of stretching the optical fiber 9 relative to the glass raw material 6 is formed. In this process, it can be observed whether the rotating cylinder 306 rotates. If the rotating cylinder 306 does not rotate, it means that the connection between the optical fiber 9 and the glass raw material 6 is good. If the rotating cylinder 306 rotates, it means that there is looseness between the optical fiber 9 and the glass raw material 6, and the connection between the optical fiber 9 and the glass raw material 6 is poor, and corresponding adjustments need to be made.

[0065] When the rotating cylinder 306 stops rotating, the sixth connecting plate 330 will move up and down, and the sixth connecting plate 330 drives the moving ring 318 to move up and down through the fifth connecting rod 331, and the moving ring 318 drives the regulating ring 322 to move up and down, and the regulating ring 322 drives the cleaning plate 334 to move up and down through the sixth connecting rod 333, and the cleaning plate 334 is always against the side wall of the glass raw material 6, thereby performing a cleaning operation on the side wall of the glass raw material 6, cleaning the glue that may exist on the side wall of the glass raw material 6, and maintaining the cleanliness of the glass raw material 6;

[0066] During the up-and-down movement of the cleaning plate 334, the sensor 335 is activated to send out a corresponding electrical signal. During the up-and-down movement of the cleaning plate 334, if the electrical signal sent out by the sensor 335 is in a constant state and does not change, it means that there is no glue on the side wall of the glass raw material 6 or the glue has been cleaned. If the electrical signal is in a changing state, it means that there is glue on the side wall of the glass raw material 6.
