Description

Technical Field

[0001] This invention relates to the field of optical module manufacturing technology, specifically to an automatic mounting and positioning device for optical module PCB boards and optical components. Background Technology

[0002] With the rapid development of data centers and 5G communication technology, the market demand for high-speed optical modules has exploded. The mounting and positioning of optical module PCB boards and optical components is a core process in the production of optical modules, and its accuracy and efficiency directly determine the optical performance and production capacity of optical modules.

[0003] Currently, Chinese invention patent application CN121692630A discloses an optical module chuck positioning component, mounting system, equipment, and mounting method. This technical solution achieves rapid loading and unloading by setting a movable first positioning part, and accurately adjusts the spacing between the clamping mechanism and the circuit board with a second positioning part, which improves the positioning efficiency and stability of fiber array mounting to a certain extent. However, this prior art still has significant shortcomings. It adopts a single-station or dual-station linear processing mode, which cannot achieve the simultaneous loading of optical components, PCB board loading, mounting positioning, and finished product output, making it difficult to meet the needs of large-scale mass production. At the same time, this technical solution does not set up a closed mounting processing cavity, and dust, airflow, and vibration in the external environment can easily interfere with the mounting process, resulting in large fluctuations in mounting accuracy. In addition, this technical solution lacks effective anti-oxidation protection measures, and the optical module PCB board and optical components are prone to oxidation during the mounting process, affecting the long-term reliability and service life of the product.

[0016] Compared with existing technologies, it has the following advantages:

[0017] 1. By rotating the servo motor to drive the mounting frame to rotate 90 degrees each time, the four workstations can simultaneously complete the optical component loading, PCB board loading, mounting positioning, and finished product unloading operations, which greatly shortens the processing cycle of a single workpiece and significantly improves the production efficiency of optical module mounting; the combined drive method of the first servo electric cylinder and the telescopic positioning rod can not only provide sufficient driving force for the optical component positioning frame, but also ensure the straightness and stability of the optical component positioning frame during horizontal movement, effectively avoiding positional deviation of the optical component during movement.

[0018] 2. The combination of the board positioning frame and the optical component positioning frame forms a closed mounting cavity, effectively isolating the mounting process from external vibrations, airflow, and dust, significantly improving the mounting positioning accuracy of the optical module PCB and the optical component. The sealing ring at the bottom of the board positioning frame and the sealing groove at the top of the optical component positioning frame work together to further enhance the sealing of the processing cavity, ensuring the stability of the environment inside the processing cavity. The center correction mechanism, consisting of a servo linear slide, positioning slider, and miniature electric cylinder around the bottom of the movable mounting board, can accurately correct the center position of PCBs of different sizes, enabling high-precision coaxial alignment between the PCB and the optical component below, effectively reducing mounting deviations and improving product yield.

[0019] 3. Nitrogen gas is introduced into the gas supply pipe through the gas inlet. The nitrogen gas enters the closed mounting processing chamber evenly through the gas supply pipe and gas inlet, which can quickly expel the air in the processing chamber to form an oxygen-free nitrogen protective atmosphere. This effectively avoids oxidation of the optical module PCB board and optical components during the mounting process, and significantly improves the reliability and service life of the optical module products. The positioning servo electric cylinders around the optical component positioning frame drive the rubber positioning blocks to position the optical components. It can be flexibly adjusted according to optical components of different sizes, which improves the versatility of the device.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an automatic mounting and positioning device for optical module PCB boards and optical components.

[0032] Example 1:

[0033] Please see Figures 1 to 8 As shown, an automatic mounting and positioning device for optical module PCB boards and optical components includes: a processing frame 1 and a sealing cover 2. The sealing cover 2 is fixed to the top of the processing frame 1 by bolts. A board conveying frame 4 and an optical component inlet 3 are respectively provided on the upper and lower sides of the front of the processing frame 1. A board inlet is also provided on one side of the board conveying frame 4, and a workpiece outlet 5 is provided on the left side of the processing frame 1 for sending out the workpiece after mounting. The board inlet, the optical component inlet 3, and the workpiece outlet 5 are all equipped with movable sealing plates inside. When the device is not performing mounting processing on the optical module PCB board and optical components, the movable sealing plates seal the inside of the board inlet, the optical component inlet 3, and the workpiece outlet 5 to prevent external dust from contaminating the internal structure of the mounting and positioning device.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, a rotary servo motor 7 is fixedly installed in the middle of the bottom of the processing frame 1, and a mounting rotating frame 8 is rotatably installed in the middle of the inside of the processing frame 1. The top of the output shaft of the rotary servo motor 7 is fixedly connected to the bottom of the mounting rotating frame 8. The mounting rotating frame 8 is controlled to rotate inside the processing frame 1 by the output shaft of the rotary servo motor 7. Each rotation angle is 90 degrees, so as to realize continuous automatic mounting and positioning processing of optical module PCB board and optical components.

[0035] Furthermore, four first servo cylinders 12 are fixedly installed at the lower part of the interior of the mounting rotating frame 8. Optical component positioning frames 9 are movably installed via the drive ends of the four first servo cylinders 12. The four first servo cylinders 12 are equidistantly distributed about the central axis of the mounting rotating frame 8. Two telescopic positioning rods 13 are fixedly installed around the lower surface of the mounting rotating frame 8, and the movable ends of the telescopic positioning rods 13 are fixedly connected to one side of each of the four optical component positioning frames 9. The drive ends of the first servo cylinders 12 control the optical component positioning frames 9 to be pushed horizontally to one side, ensuring stability of the optical component positioning frames 9 during horizontal pushing in conjunction with the movable ends of the four telescopic positioning rods 13. Mounting control frames 10 are fixedly installed around the upper surface of the mounting rotating frame 8, and the four mounting control frames 10 are symmetrically arranged directly above the four optical component positioning frames 9. A mounting plate 14 is movably installed below each mounting control frame 10, and a board positioning frame 11 is movably installed at the bottom of each mounting plate 14. Through the cooperation between the board positioning frame 11 and the optical component positioning frame 9, a closed processing cavity is formed for the optical module PCB board and the optical component during automatic mounting and positioning, thereby improving the automatic mounting and positioning processing accuracy of the optical module PCB board and the optical component.

[0036] Specifically, the top of the processing frame 1 is bolted with a closed cover 2, providing a basic enclosed space for the entire mounting process. The board conveyor 4 and the optical component inlet 3 on the upper and lower sides of the front of the processing frame 1 respectively realize the independent feeding of the optical module PCB board and the optical component. The workpiece outlet 5 on the left side of the processing frame 1 automatically feeds out the workpiece after mounting. The movable sealing plates inside the board inlet, optical component inlet 3 and workpiece outlet 5 close the corresponding channels when the device stops to prevent external dust from entering and contaminating the internal precision structure. The rotating servo motor 7 in the middle of the bottom of the processing frame 1 drives the mounting rotating frame 8 in the middle of the interior to rotate intermittently. Each rotation angle is 90 degrees, so that the four stations on the mounting rotating frame 8 complete the feeding, positioning, mounting and unloading operations in sequence, realizing continuous automatic mounting and positioning processing. Four first servo electric cylinders 12, evenly distributed at the lower part of the mounting rotary frame 8, drive the corresponding optical component positioning frame 9 to move horizontally. Simultaneously, telescopic positioning rods 13, located around the lower surface of the mounting rotary frame 8, are fixedly connected to one side of the optical component positioning frame 9, providing guidance and support during the horizontal movement of the optical component positioning frame 9, ensuring stability during the movement. Four mounting control frames 10, symmetrically positioned directly above the four optical component positioning frames 9, are located around the upper surface of the mounting rotary frame 8. The mounting plate 14 below each mounting control frame 10 drives the board positioning frame 11 to complete the PCB board positioning and mounting actions. The board positioning frame 11 and the optical component positioning frame 9 cooperate to form a closed processing cavity, isolating the mounting process from external vibrations, airflow, and dust.

[0037] In use, the four-station rotary continuous processing structure greatly improves the production efficiency of optical module mounting. The independent feeding and discharging channels, combined with the movable enclosed plate, effectively reduce the maintenance frequency of the equipment. The combined drive method of the first servo electric cylinder 12 and the telescopic positioning rod 13 takes into account both the movement accuracy and structural stability of the optical component positioning frame 9. The enclosed processing cavity can significantly improve the mounting positioning accuracy of the optical module PCB board and the optical component, and reduce mounting deviation.

[0038] Example 2:

[0039] like Figure 4-7 As shown, each mounting control frame 10 is equipped with a sliding servo cylinder 16, and each mounting plate 14 has a connecting sliding frame 17 fixedly mounted on one side of its top. The drive end of the sliding servo cylinder 16 is fixedly connected to one side of the connecting sliding frame 17. The bottom of the mounting control frame 10 has connecting grooves 28 on both sides that mate with the connecting sliding frame 17, and one side of the connecting sliding frame 17 is slidably connected to the interior of the connecting groove 28. The driving end of the sliding servo cylinder 16 controls the connecting sliding frame 17 to slide to one side, thereby adjusting the position of the board positioning frame 11. When feeding the optical module PCB, the driving end of the sliding servo cylinder 16 pushes the connecting sliding frame 17 to one side of the board conveyor 4, achieving automatic feeding of the optical module PCB.

[0040] Furthermore, lifting servo cylinders 15 are fixedly installed around the top of the mounting plate 14, and the drive ends of the four lifting servo cylinders 15 are fixedly connected to the top of the board positioning frame 11. Movable grooves 29 are provided on both sides of the bottom of the mounting control frame 10 to provide sliding space for the lifting servo cylinders 15. The mounting control frame 10 is controlled to move downward by the drive ends of the four lifting servo cylinders 15, so as to realize the mating connection between the board positioning frame 11 and the board positioning frame 11.

[0041] Furthermore, a second servo electric cylinder 18 is fixedly installed around the upper part of the board positioning frame 11. A movable mounting plate 19 is movably installed inside the board positioning frame 11, and the drive ends of the four second servo electric cylinders 18 are fixedly connected to the top of the movable mounting plate 19. A servo linear slide 24 is fixedly installed around the bottom of the movable mounting plate 19, and a positioning slider 25 is slidably installed at the bottom of the four servo linear slides 24. A miniature electric cylinder 26 is fixedly installed at the bottom of each positioning slider 25, and a movable positioning plate 27 is fixedly installed at the drive end of the miniature electric cylinder 26.

[0042] Furthermore, a vacuum adsorption rack 20 is fixedly provided in the middle of the bottom of the movable mounting board 19, and the bottom of the vacuum adsorption rack 20 is provided with several vacuum adsorption holes. The bottom surface of the vacuum adsorption rack 20 is covered with a rubber pad to protect the adsorption surface of the PCB board.

[0043] In use, the movable mounting plate 19 is moved downward by the drive end of the second servo electric cylinder 18 until the bottom surface of the vacuum adsorption frame 20 contacts the upper surface of the PCB board. The movable positioning plate 27 is moved downward by the miniature electric cylinders 26 around the perimeter, and the movable positioning plate 27 is centered around the perimeter of the PCB board by the positioning sliders 25 around the perimeter. Finally, the upper surface of the PCB board is adsorbed and positioned by several vacuum adsorption holes at the bottom of the vacuum adsorption frame 20, thus completing the stable loading operation of the optical module PCB board.

[0044] Furthermore, a gas inlet 6 is fixedly provided at the center of the top of the sealing cover 2, and a gas supply pipe 21 is fixedly provided inside the mounting rotating frame 8, with the top end of the gas supply pipe 21 rotatably and sealingly connected to the bottom end of the gas inlet 6; several gas supply pipes 22 are also fixedly provided below the inside of the gas supply pipe 21, and several gas holes 23 are provided on both sides of the inner wall of the board positioning frame 11, with one end of each of the gas supply pipes 22 communicating with the inside of the gas holes 23. Nitrogen gas is supplied into the inside of the gas supply pipe 21 through the gas inlet 6, and nitrogen gas is filled into the mounting positioning space in conjunction with the gas supply pipes 22 and the several gas holes 23, to prevent oxidation of the optical module PCB and optical components during the mounting positioning process.

[0045] Furthermore, a sealing ring 30 is fixedly provided at the bottom of the board positioning frame 11, and a sealing groove 31 that cooperates with the sealing ring 30 is provided at the top of the optical component positioning frame 9; several positioning servo cylinders 32 are fixedly provided around the optical component positioning frame 9, and the driving ends of the several positioning servo cylinders 32 are provided with rubber positioning blocks. By placing the optical component inside the optical component positioning frame 9, the driving ends of the several positioning servo cylinders 32 around the frame drive the rubber positioning blocks to contact the sides of the optical component, thereby performing a positioning operation on the optical component inside the optical component positioning frame 9, ensuring the stability of the mounting and positioning of the optical component and the optical module PCB board.

[0046] Specifically, the sliding servo cylinder 16 inside each mounting control frame 10 drives the mounting plate 14 to slide horizontally along the connecting slide grooves 28 on both sides of the bottom of the mounting control frame 10 via the connecting sliding frame 17 fixed to one side of the top of the mounting plate 14. When the optical module PCB board is fed, the board positioning frame 11 is moved to one side of the board conveyor 4 to complete the automatic feeding. The movable grooves 29 on both sides of the bottom of the mounting control frame 10 provide sufficient sliding space for the lifting servo cylinder 15. The four lifting servo cylinders 15 around the top of the mounting plate 14 drive the board positioning frame 11 to rise and fall vertically, realizing the precise docking of the board positioning frame 11 and the optical component positioning frame 9. Four second servo electric cylinders 18 on the upper perimeter of the board positioning frame 11 drive the movable mounting plate 19 downwards, so that the bottom surface of the vacuum adsorption frame 20 at the bottom center of the movable mounting plate 19 contacts the upper surface of the PCB board. The servo linear slides 24 on the bottom perimeter of the movable mounting plate 19 drive the positioning slider 25 to move horizontally. The miniature electric cylinders 26 at the bottom of the positioning slider 25 drive the movable positioning plate 27 downwards and correct the center position of the PCB board. Finally, the PCB board is adsorbed and positioned by several vacuum adsorption holes at the bottom of the vacuum adsorption frame 20. The rubber pad on the bottom surface of the vacuum adsorption frame 20 can prevent scratches on the PCB board surface during adsorption. The air inlet 6 at the top center of the sealed cover 2 is rotatably and sealed to the top of the air supply pipe 21 inside the mounting rotating frame 8. Several air inlets 22 inside the lower part of the air supply pipe 21 are connected to the air inlets 23 on both sides of the inner wall of the board positioning frame 11. Nitrogen gas is introduced into the air supply pipe 21 through the air inlet 6. The nitrogen gas enters the closed mounting positioning space through the air inlets 22 and the air inlets 23 to prevent oxidation of the optical module PCB and optical components during the mounting process. The sealing ring 30 at the bottom of the board positioning frame 11 cooperates with the sealing groove 31 at the top of the optical component positioning frame 9 to further enhance the sealing of the processing cavity. Several positioning servo electric cylinders 32 around the optical component positioning frame 9 drive the rubber positioning blocks to contact the sides of the optical components for precise positioning.

[0047] The system achieves fully automated feeding and centering of optical module PCBs without manual intervention, significantly improving the automation level of production. The adjustable centering mechanism can adapt to PCBs and optical components of different sizes, significantly improving the versatility of the device. The nitrogen protection system effectively prevents oxidation of components during the mounting process, improving the reliability and service life of optical module products. The cooperation between the sealing ring 30 and the sealing groove 31 not only ensures the effectiveness of nitrogen protection but also further isolates external environmental interference, further improving the mounting positioning accuracy.

[0048] The working principle is as follows:

[0049] The servo motor 7 drives the mounting rotating frame 8 to rotate to the initial position, so that the first optical component positioning frame 9 is aligned with the optical component inlet 3. The optical component to be mounted is placed inside the optical component positioning frame 9. Several positioning servo electric cylinders 32 around the optical component positioning frame 9 are activated to drive the rubber positioning block to move to the side of the optical component and clamp it evenly, thus completing the initial positioning of the optical component.

[0050] The servo motor 7 drives the mounting rotating frame 8 to rotate 90 degrees clockwise, so that the optical component positioning frame 9, which has completed the positioning of the optical component, moves to the loading station corresponding to the board conveyor frame 4. At the same time, the next empty optical component positioning frame 9 rotates to the loading station corresponding to the optical component inlet 3, and the loading and positioning operation of the next optical component is carried out synchronously.

[0051] Start the sliding servo cylinder 16 inside the mounting control frame 10 corresponding to the loading station, drive the connecting sliding frame 17 to slide along the connecting slide grooves 28 on both sides of the bottom of the mounting control frame 10 toward the board conveyor frame 4, and move the mounting plate 14 and the board positioning frame 11 to the top of the board conveyor frame 4. The movable grooves 29 on both sides of the bottom of the mounting control frame 10 provide sufficient sliding space for the lifting servo cylinder 15. Start the lifting servo cylinders 15 around the top of the mounting plate 14, and drive the board positioning frame 11 to move downward to near the upper surface of the board conveyor frame 4.

[0052] The second servo electric cylinder 18 on the upper perimeter of the board positioning frame 11 is activated, driving the movable mounting plate 19 to move downwards until the rubber pad on the bottom of the vacuum adsorption frame 20 at the bottom center of the movable mounting plate 19 makes smooth contact with the upper surface of the optical module PCB on the board conveyor 4. The servo linear slides 24 on the bottom perimeter of the movable mounting plate 19 are activated, driving the positioning slider 25 to move synchronously to the side of the PCB. At the same time, the miniature electric cylinder 26 at the bottom of the positioning slider 25 is activated, driving the movable positioning plate 27 to move downwards and fit tightly against the side of the PCB. The movable positioning plates 27 in four directions work together to correct the center position of the PCB. After the correction is completed, the vacuum adsorption system is activated, and the PCB is stably adsorbed and fixed through several vacuum adsorption holes at the bottom of the vacuum adsorption frame 20.

[0053] Start the lifting servo cylinder 15 to drive the board positioning frame 11 to move upward to the preset height. Start the sliding servo cylinder 16 to drive the connecting sliding frame 17 to slide in the opposite direction along the connecting slide groove 28, so as to drive the board positioning frame 11 and the PCB board fixed by adsorption back to the position directly above the lower optical component positioning frame 9. Start the lifting servo cylinder 15 again to drive the board positioning frame 11 to move downward, so that the sealing ring 30 at the bottom of the board positioning frame 11 is completely embedded in the sealing groove 31 at the top of the optical component positioning frame 9, forming a closed mounting processing cavity that isolates the external environment.

[0054] The external nitrogen source is turned on, and nitrogen is continuously supplied to the gas supply pipe 21 inside the mounting rotating frame 8 through the gas inlet 6. The nitrogen enters the closed mounting processing chamber evenly through several gas inlets 22 at the bottom of the gas supply pipe 21 and the gas inlets 23 on both sides of the inner wall of the board positioning frame 11. The air in the processing chamber is quickly discharged to form an oxygen-free nitrogen protective atmosphere. The first servo electric cylinder 12 inside the mounting rotating frame 8 is activated to drive the optical component positioning frame 9 to perform micron-level precise micro-adjustment in the horizontal direction. At the same time, the telescopic positioning rod 13 below the surface of the mounting rotating frame 8 ensures the straightness and stability of the movement process, so that the optical component and the PCB board above can be aligned with high precision. After the alignment is completed, the second servo electric cylinder 18 is activated to drive the movable mounting plate 19 to move downward at a preset speed, so that the PCB board that is adsorbed and fixed is tightly attached to the optical component, completing the mounting and positioning operation of the optical module PCB board and the optical component.

[0055] After the placement and positioning are completed, the nitrogen gas source is turned off, and the residual nitrogen gas inside the placement processing chamber is discharged through the gas guide port 6. The second servo electric cylinder 18 is started to drive the movable placement plate 19 to return to the initial position. The vacuum adsorption system is turned off to release the adsorption and fixation of the PCB board. The lifting servo electric cylinder 15 is started to drive the board positioning frame 11 to move upward to the initial height, so that the sealing ring 30 and the sealing groove 31 are completely separated. The servo motor 7 is rotated to drive the placement rotating frame 8 to rotate 90 degrees clockwise again, so that the workpiece that has been placed is moved to the discharge station corresponding to the workpiece discharge port 5. At the same time, the workpiece at the loading station is moved to the placement station for processing, and the workpiece at the feeding station is moved to the loading station for PCB board loading operation.

[0056] Start the first servo cylinder 12 corresponding to the material discharge station to drive the optical component positioning frame 9 to move horizontally to the side of the workpiece discharge port 5. At the same time, start the positioning servo cylinders 32 around the optical component positioning frame 9 to drive the rubber positioning blocks to release the optical module workpiece that has been mounted. Take the workpiece out from inside the optical component positioning frame 9 and send it out of the device through the workpiece discharge port 5 to complete a complete mounting processing cycle. Repeat the above steps to realize the continuous automated mounting and positioning processing of optical module PCB board and optical component.
