Description
Technical Field
[0001] This invention relates to an automated coupling mechanism for optical devices, belonging to the field of optical communication technology. Background Technology
[0002] In the field of optical chips, optical coupling testing is a crucial step in evaluating their performance. Current methods involve manually adjusting the clamping of the test fiber to align it with the test port, and then manually moving the fiber to the next port after testing one (the output port of the optical device). However, this manual coupling method is not only cumbersome and time-consuming, but also demands a high level of skill and expertise from the testers, making it difficult to perform optical coupling testing of optical chips quickly and easily, and also compromising the accuracy of the test results. Summary of the Invention
[0003] The purpose of this invention is to provide an automated coupling mechanism for optical devices, which can effectively reduce interference from human factors and improve the pass rate of product processing and processing efficiency during multiple uses.
[0004] To achieve the above objectives, the technical solution adopted by the present invention is: an automated coupling mechanism for optical devices, including a base, a stage for mounting a PCB board, a lens clamping mechanism located above the stage, and a Z-axis movable seat on which the stage is mounted and can move in the vertical direction. The lens clamping mechanism is mounted on the base via an XY drive platform and can move in the X and Y directions with the XY drive platform. A vertically arranged support plate is installed on the base outside the XY drive platform. The Z-axis movable seat is movably installed on one side surface of the support plate. A drive block is installed on the side end face of the Z-axis movable seat. A rotating shaft is rotatably installed on the support plate directly below the drive block. The lower part of a rotating plate is fitted onto the rotating shaft and can rotate with the rotating shaft. A connecting rod is hinged to the upper part of the rotating plate. The lower end of the connecting rod is connected to the rotating plate, and the upper end is hinged to the movable seat spaced apart directly below the drive block. The upper end of a vertically arranged pin is fixedly connected to the drive block, and the lower end of the pin is movably connected to the movable seat so that the movable seat and the pin can move relative to each other in the vertical direction. A first elastic element is disposed between the drive block and the movable seat and is fitted onto the pin. When the first elastic element is in an uncompressed state, the connection between the connecting rod and the rotating plate is located on one side of the vertical line connecting the movable seat and the rotating shaft. A rotating rod is disposed above the drive block. The rotating rod is rotatably mounted on a support base and located in the mounting groove of the support base. One end of the rotating rod protrudes from the support base and contacts the upper surface of the drive block. The other end of the rotating rod protruding from the support base is used to contact the upper surface of the stop block disposed below it. A second elastic element located directly above the stop block is installed between the rotating rod and the support base. The ratio of the distance from the rotation center of the rotating rod to its one end above the drive block to its other end is 1:3.
[0005] The following are further improvements to the above technical solution: 1. In the above scheme, the stop block is mounted on an adjusting rod, and the adjusting rod is mounted on a support plate and can move in the vertical direction.
[0006] 2. In the above scheme, the lower end of the pin shaft has a vertically oriented strip hole, and the movable seat has a pin hole corresponding to the strip hole. A pin passes through the pin hole on the movable seat and the strip hole on the pin shaft to movably connect the lower end of the pin shaft to the movable seat.
[0007] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: 1. The automated coupling mechanism for optical devices of the present invention has a lens clamping mechanism mounted on a base via an XY drive platform, which can move in the X and Y directions with the XY drive platform. A vertically arranged support plate is mounted on the base outside the XY drive platform. A Z-axis movable seat is movably mounted on one side surface of the support plate. The upper end of a vertically arranged pin is fixedly connected to a drive block, and the lower end of the pin is movably connected to the movable seat, allowing the movable seat and the pin to move relative to each other in the vertical direction. When the first elastic element is in an uncompressed state, the connection between the connecting rod and the rotating plate is located on one side of the vertical line connecting the movable seat and the rotating shaft. This can effectively reduce interference from human factors, improve the yield rate of processing, improve the vertical positional accuracy between the lens to be bonded and the PCB board, and avoid the distance deviation caused by the slight fall of the Z-axis movable seat, further improving the product processing qualification rate.
[0008] 2. The automated coupling mechanism of the optical device of the present invention has a rotating rod disposed above the driving block. The rotating rod is rotatably mounted on a support base and located in the mounting groove of the support base. One end of the rotating rod protrudes from the support base and contacts the upper surface of the driving block. The other end of the rotating rod protruding from the support base is used to contact the upper surface of the stop block disposed below it. A second elastic element located directly above the stop block is installed between the rotating rod and the support base to achieve elastic limiting of the Z-axis movable seat, avoid vibration and displacement caused by hard impact, ensure the positional accuracy of the Z-axis movable seat, and also allow the rotating rod to automatically return to the initial position, improving the processing efficiency in multiple uses.

[0011] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.
[0012] Example 1: An automated coupling mechanism for an optical device includes a base 1, a platform 3 for mounting a PCB board 2, a lens clamping mechanism 4 located above the platform 3, and a Z-axis movable seat 5 on which the platform 3 is mounted and can move in the vertical direction. The lens clamping mechanism 4 is mounted on the base 1 via an XY drive platform 6 and can move in the X and Y directions with the XY drive platform 6. A vertically arranged support plate 7 is mounted on the base 1 outside the XY drive platform 6. The Z-axis movable seat 5 is movably mounted on one side surface of the support plate 7. A drive block 8 is mounted on the side end face of the Z-axis movable seat 5. A rotating shaft 9 is rotatably mounted on the support plate 7 directly below the drive block 8. The lower part of a rotating plate 10 is fitted onto the rotating shaft 9 and can rotate with the rotating shaft 9. A connecting rod 11 is hinged to the upper part of the rotating plate 10. The lower end of the connecting rod 11 is connected to the rotating plate 10, and the upper end... The movable seat 12 is hinged to the drive block 8 and is spaced below the drive block 8. The upper end of the vertically arranged pin 13 is fixedly connected to the drive block 8, and the lower end of the pin 13 is movably connected to the movable seat 12, so that the movable seat 12 and the pin 13 can move relative to each other in the vertical direction. A first elastic element 14 is disposed between the drive block 8 and the movable seat 12 and is fitted onto the pin 13. When the first elastic element 14 is in an uncompressed state, the connection between the connecting rod 11 and the rotating plate 10 is located on one side of the vertical line connecting the movable seat 12 and the rotating shaft 9. A rotating rod 18 is provided above the driving block 8. The rotating rod 18 is rotatably mounted on a support base 19 and located in the mounting groove 191 of the support base 19. One end of the rotating rod 18 protrudes from the support base 19 and contacts the upper surface of the driving block 8. The other end of the rotating rod 18 protruding from the support base 19 is used to contact the upper surface of the stop block 20 located below it. A second elastic element 21 located directly above the stop block 20 is installed between the rotating rod 18 and the support base 19.
[0013] The aforementioned stop block 20 is mounted on an adjusting rod 22, which is mounted on a support plate 7 and can move vertically.
[0014] The lower end of the aforementioned pin 13 has a vertically oriented strip hole 16, and the aforementioned movable seat 12 has a pin hole 17 corresponding to the strip hole 16. A pin passes through the pin hole 17 on the movable seat 12 and the strip hole 16 on the pin 13, thereby movably connecting the lower end of the pin 13 to the movable seat 12.
[0015] Example 2: An automated coupling mechanism for an optical device includes a base 1, a platform 3 for mounting a PCB board 2, a lens clamping mechanism 4 located above the platform 3, and a Z-axis movable seat 5 on which the platform 3 is mounted and can move in the vertical direction. The lens clamping mechanism 4 is mounted on the base 1 via an XY drive platform 6 and can move in the X and Y directions with the XY drive platform 6. A vertically arranged support plate 7 is mounted on the base 1 outside the XY drive platform 6. The Z-axis movable seat 5 is movably mounted on one side surface of the support plate 7. A drive block 8 is mounted on the side end face of the Z-axis movable seat 5. A rotating shaft 9 is rotatably mounted on the support plate 7 directly below the drive block 8. The lower part of a rotating plate 10 is fitted onto the rotating shaft 9 and can rotate with the rotating shaft 9. A connecting rod 11 is hinged to the upper part of the rotating plate 10. The lower end of the connecting rod 11 is connected to the rotating plate 10, and the upper end... The movable seat 12 is hinged to the drive block 8 and is spaced below the drive block 8. The upper end of the vertically arranged pin 13 is fixedly connected to the drive block 8, and the lower end of the pin 13 is movably connected to the movable seat 12, so that the movable seat 12 and the pin 13 can move relative to each other in the vertical direction. A first elastic element 14 is disposed between the drive block 8 and the movable seat 12 and is fitted onto the pin 13. When the first elastic element 14 is in an uncompressed state, the connection between the connecting rod 11 and the rotating plate 10 is located on one side of the vertical line connecting the movable seat 12 and the rotating shaft 9. A rotating rod 18 is provided above the driving block 8. The rotating rod 18 is rotatably mounted on a support base 19 and located in the mounting groove 191 of the support base 19. One end of the rotating rod 18 protrudes from the support base 19 and contacts the upper surface of the driving block 8. The other end of the rotating rod 18 protruding from the support base 19 is used to contact the upper surface of the stop block 20 located below it. A second elastic element 21 located directly above the stop block 20 is installed between the rotating rod 18 and the support base 19.
[0016] The ratio of the distance from the rotation center of the aforementioned rotating rod 18 to one end above the drive block 8 to the other end is 1:3~8.
[0017] The lower end of the aforementioned pin 13 has a vertically oriented strip hole 16, and the aforementioned movable seat 12 has a pin hole 17 corresponding to the strip hole 16. A pin passes through the pin hole 17 on the movable seat 12 and the strip hole 16 on the pin 13, thereby movably connecting the lower end of the pin 13 to the movable seat 12.
[0018] In use, the rotating shaft 9 can be driven to rotate by the handle at one end of the rotating shaft 9, thereby causing the rotating plate 10 to rotate around the rotating shaft 9. Then, the rotating plate 10 drives the connecting rod 11 to rotate around the connection point between the connecting rod 11 and the movable seat 12 as the fulcrum. This causes the connection point between the connecting rod 11 and the rotating plate 10 to continuously approach the vertical line between the movable seat 12 and the rotating shaft 9. During this process, the pin 13 in the movable seat 12 first moves upward and pushes the drive block 8 and the Z-axis movable seat 5 upward until the Z-axis movable seat 5 rises to a suitable position and is stopped. The rotating shaft 9 continues to rotate. At this time, the pin 13 remains stationary, the movable seat 12 moves upward and squeezes the first elastic element 14 until the connection point between the connecting rod 11 and the rotating plate 10 crosses the vertical line between the movable seat 12 and the rotating shaft 9.
[0019] When using the aforementioned automated coupling mechanism for optical devices, the lens clamping mechanism is mounted on a base via an XY drive platform and can move in the X and Y directions with the XY drive platform. A vertically arranged support plate is mounted on the base outside the XY drive platform. The Z-axis movable seat is movably mounted on one side surface of the support plate. The upper end of a vertically arranged pin is fixedly connected to the drive block, and the lower end of the pin is movably connected to the movable seat, allowing the movable seat and the pin to move relative to each other in the vertical direction. When the first elastic element is in an uncompressed state, the connection point between the connecting rod and the rotating plate is located on one side of the movable seat and the rotating shaft. This can effectively reduce interference from human factors, improve the yield rate of the processed product, improve the vertical positional accuracy between the lens to be bonded and the PCB board, and avoid the distance deviation caused by the slight fall of the Z-axis movable seat, further improving the product processing qualification rate. Furthermore, a rotating rod is provided above the drive block. The rotating rod is rotatably mounted on a support base and located in the mounting groove of the support base. One end of the rotating rod protrudes from the support base and contacts the upper surface of the drive block. The other end of the rotating rod protruding from the support base is used to contact the upper surface of the stop block located below it. A second elastic element located directly above the stop block is installed between the rotating rod and the support base to achieve elastic limiting of the Z-axis movable seat, avoid vibration and displacement caused by hard impact, ensure the positional accuracy of the Z-axis movable seat, and also allow the rotating rod to automatically return to the initial position, improving the processing efficiency in multiple uses.

They should not be construed as limiting the scope of protection of the present invention.
