Description

Technical Field

[0001] This utility model relates to the field of BOSA production technology, and in particular to a BOSA pressing and mixing device. Background Technology

[0002] BOSA (Bodied Optical Component Assembly) is a crucial optoelectronic device for communication, requiring extremely high manufacturing precision. The BOSA production process involves pressing the BOSA housing (quadrilateral base) together with the TO (laser diode) fitting, demanding consistent pressing height. Traditional pressing equipment primarily employs pneumatic pressing methods. However, the excessive vibration during pneumatic pressing can easily damage the product. Automating this process in a production line design requires assembling and transporting the TO fitting and fitting to the pressing equipment. However, due to the small and delicate nature of BOSAs, the equipment for these loading processes is inconvenient to arrange. Setting up the processes in an assembly line format would occupy significant space, leading to a sharp increase in costs, especially for small fiber optic head welding processes. Based on this, this utility model proposes a BOSA pressing and assembly device, which provides a four-station rotary conveying mechanism, so that the TO tube feeding process and the square seat feeding process can be arranged next to the corresponding stations of the rotary conveying mechanism, realizing the feeding and transmission of each component in a small space, and the pressing and assembly method of the pressing mechanism has high output stability and strong reliability. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a BOSA pressing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a BOSA pressing device, comprising a pressing mechanism, the pressing mechanism including a base, supporting side plates fixed on the top two sides of the base respectively, a top plate connected to the top of the two supporting side plates, a first layer and a second layer arranged from top to bottom in the middle and lower part of the supporting side plates, a screw rotatably connected between the first layer and the top plate, a pressing drive motor fixed at the bottom of the second layer, the output shaft of the pressing drive motor vertically upward and connected to the bottom end of the screw through a coupling; a screw block threadedly connected to the screw, a slide rail fixed to the front side of the two supporting side plates, a slide seat slidably connected to the slide rail, a movable plate fixed to the front side of the two slide seats, the movable plate having a through hole, the front side of the screw block extending outward and passing through the through hole, a pressing block fixed to the bottom of the front side of the screw block, a rotary conveying mechanism provided on the front side of the pressing mechanism, the rotary conveying mechanism having four positioning seats.

[0005] Furthermore, the pressing block has a frustum structure.

[0006] Furthermore, the rotary conveying mechanism includes a rotary drive motor and a four-station divider. Both the rotary drive motor and the four-station divider are mounted on a fixed plate. The four-station divider is positioned above the rotary drive motor. A drive wheel is fixed to the output end of the rotary drive motor, and a driven wheel is fixed to the input end of the four-station divider. The drive wheel and the driven wheel are connected by a conveyor belt. A rotating disk is fixed to the output end of the four-station divider, and four positioning seats are positioned on the rotating disk.

[0007] Furthermore, a rotary joint is provided in the middle of the rotary disk; the positioning seat includes a TO positioning seat, which is rotatably connected to the rotary disk via a bearing one, and a fixture limiting flange mounted on the rotary disk is sleeved on the outer side of the TO positioning seat, the bottom of the fixture limiting flange being rotatably connected to the TO positioning seat via a bearing two; a TO clamping seat is provided on the top outer side of the TO positioning seat, a bushing is provided between the bottom of the TO clamping seat and the TO positioning seat, a spring is sleeved on the bottom of the TO positioning seat at the bushing, the TO positioning seat is provided with a positioning hole and an air passage from top to bottom, the two being connected, and the bottom of the TO positioning seat passes downward through the rotary disk and is connected to a first rotary joint; the outer surface of the rotary joint is connected to multiple quick connectors for connecting to an external vacuum source, and multiple second rotary joints are provided at its bottom, the second rotary joints and the first rotary joints being connected via air pipes.

[0008] Furthermore, a convex ring is provided in the middle of the TO positioning seat, the second bearing is located below the convex ring, and the spring is located above the convex ring.

[0009] Furthermore, the top of the TO clamping seat is provided with an opening, and a square seat placement platform is provided along the inner edge of the opening.

[0010] Furthermore, the four positioning seats are evenly distributed on the rotating disk.

[0011] Beneficial effects

[0012] Compared to existing technologies, this utility model has at least the following advantages: The four-station rotary conveyor mechanism of this utility model facilitates the arrangement of the TO tube feeding process and the square seat feeding process next to their corresponding stations. Feeding proceeds in the order of TO tube feeding followed by square seat feeding, and then, in conjunction with the pressing mechanism, the BOSA is press-fitted. This results in high pressing efficiency, improved product reliability, and space-saving design for automated production lines. The pressing drive motor, screw, screw block, and pressing block work together to press-fit the square seat and TO tube, which is less likely to damage the product compared to pneumatic pressing. The TO clamping seat on the rotary conveyor structure floats relative to the TO positioning seat, ensuring better alignment and fit between the square seat and TO tube during pressing, avoiding assembly difficulties or damage due to positional deviations. Furthermore, during pressing, the TO clamping seat can move downwards to buffer some of the pressure, preventing deformation, cracking, or surface damage to the tube or square seat due to excessive impact, thus protecting the integrity and performance of the parts.

[0024] See Figures 1-7 This embodiment provides a BOSA pressing device, including a pressing mechanism and a rotary conveying mechanism disposed on the front side of the pressing mechanism.

[0025] The pressing mechanism includes a base 90, with supporting side plates 91 fixed to the top two sides of the base 90. A U-shaped top plate 92 is connected to the top of the two supporting side plates 91. A first layer 93 and a second layer 94 are arranged from top to bottom on the lower middle part of each supporting side plate 91. A screw 611 is rotatably connected between the first layer 93 and the top plate 92. A pressing drive motor 13 is fixed to the bottom of the second layer 94. The output shaft of the pressing drive motor 13 is vertically upward and connected via... The coupling is connected to the bottom end of the screw 611; the screw 611 is threadedly connected to a screw block 15; the front sides of the two support side plates 91 are fixed with slide rails 12; the slide rails 12 are slidably connected to slide blocks 10; the front sides of the two slide blocks 10 are fixed with movable plates 11; the movable plates 11 have through holes 110; the front side of the screw block 15 extends outward and passes through the through holes 110; the bottom front side of the screw block is fixed with a pressing block 150; the pressing block 150 has a frustum structure.

[0026] The rotary conveying mechanism includes a rotary drive motor 1 and a four-station divider 6. Both the rotary drive motor 1 and the four-station divider 6 are mounted on the same side of a fixed plate 2. The four-station divider 6 is positioned above the rotary drive motor 1. The output end of the rotary drive motor 1 passes through the fixed plate 2 and is fixed to a drive wheel 3. The input end of the four-station divider 6 passes through the fixed plate 2 and is fixed to a driven wheel 5. The drive wheel 3 and the driven wheel 5 are connected by a conveyor belt 4. A rotating disk 7 is fixed to the output end of the four-station divider 6, and four positioning seats 8 are provided on the rotating disk 7. The rotating disk 7 is divided into four equal parts with its center as the center. The four positioning seats are respectively positioned at the four equal division points, such that the included angle between adjacent positioning seats is 90 degrees, achieving a uniform distribution of the four positioning seats 8 on the rotating disk 7. The rotary drive motor 1 serves as the power source; when the rotary drive motor 1 is started and its output end rotates, the drive wheel 3 also rotates accordingly. The rotation of the drive wheel 3 drives the conveyor belt 4, which in turn drives the driven wheel 5. The rotation of the driven wheel 5 drives the input shaft of the four-station divider 6. When the input shaft rotates, the four-station divider 6 converts the continuous rotational motion into intermittent rotational motion, causing the rotary table 7 to rotate 90° each time. Under the action of the four-station divider 6, the rotation of the positioning seat 8 is intermittent, pausing for a period of time after each 90° rotation to facilitate corresponding operations, such as loading TO fittings, loading square seats, pressing TO fittings and square seats together, and unloading finished products.

[0027] A rotary joint 16 is provided in the middle of the rotating disk 7. The rotary joint 16 is a commercially available existing technology product. The positioning seat includes a TO positioning seat 81, which is rotatably connected to the rotating disk 7 via a bearing 86. A fixture limiting flange 80 mounted on the rotating disk is sleeved on the outer side of the TO positioning seat 81. The bottom of the fixture limiting flange 80 is rotatably connected to the TO positioning seat 81 via a bearing 85. A convex ring 812 is provided in the middle of the TO positioning seat 81, and the bearing 85 is located below the convex ring 812. In this embodiment, the bearing 86 is a thrust ball bearing, and the bearing 85 is a deep groove ball bearing.

[0028] A TO clamping seat 84 is provided on the top outer side of the TO positioning seat 81. The top of the TO clamping seat 84 has an opening, and a square seat placement platform 840 is provided on the inner edge of the opening. The top of the TO positioning seat 81 is located at the opening, and a recessed platform 813 is provided on the top of the TO positioning seat 81. There is a movable gap between the top surface of the recessed platform 813 and the top and bottom surfaces of the TO clamping seat 84. A bushing 82 is provided between the bottom of the TO clamping seat 84 and the TO positioning seat 81. A spring 83 is fitted on the bottom of the TO positioning seat 81 above the convex ring 81, so that the spring 83 is located between the convex ring 81 and the bushing 82. The TO clamping seat 84 can float under the action of the spring 83. The movable gap between the top surface of the recessed platform 813 and the top and bottom surfaces of the TO clamping seat 84 is the floating space. The top ends of the TO clamping seat 84 and the positioning seat 81 pass through the fixture limiting flange 80, and the bottom end of the TO clamping seat 84 is locked onto the top bottom surface of the fixture limiting flange 80 under the action of the spring 83. The TO positioning seat 81 is provided with a positioning hole 811 and an air passage 810 from top to bottom, which are connected, and the bottom of the TO positioning seat 81 passes downward through the rotating disk 7 and is connected to the first rotary joint 87.

[0029] The rotary joint 16 has four quick connectors 19 connected to an external vacuum source on its outer surface, and four second rotary joints 17 are provided at its bottom. The second rotary joints 17 and the first rotary joint 17 are connected by air pipes, which ensures that the positioning seat 8 and the rotary joint 16 located in the center are connected when the rotating disk 7 rotates, so that the air pipes will not be tangled or twisted during rotation, and the vacuum adsorption function will not be affected by rotation. When the TO tube 20 is placed on the TO positioning seat 81, its tube feet extend into the positioning hole 811, and its tube body is located on the top surface of the TO positioning seat 81, the external vacuum source is activated to perform vacuum adsorption on the TO tube 20.

[0030] In practical applications, the devices for TO tube loading, square seat loading, pressing, and unloading are distributed at four stations of the rotary conveyor, corresponding to the rotation direction of the rotary disk. These four stations correspond to the positions of four positioning seats 8, ensuring that the assembly of BOSA devices follows the sequence of TO tube loading, square seat loading, pressing, and unloading. This solves the problem of loading and transferring components within a limited space. The pressing drive motor 13 operates, driving the screw block 15 downwards. The movable plate 11 moves downwards accordingly, and the through hole 110 limits the movement of the screw block 15. Simultaneously, the pressing block 150 presses the TO tube 20 and square seat 18, currently positioned on the positioning seat 8 at the pressing station, together. By controlling the speed and torque of the pressing drive motor 13, precise adjustment of the screw block's movement speed and pressure is achieved, ensuring accurate and stable pressing force output. Compared to pneumatic pressing, this method is less likely to damage the product.

[0031] During the pressing process, the square seat 18 is positioned on the square seat placement platform 840 of the TO clamping seat 84, and the TO fitting 20 is positioned on top of the TO positioning seat 81. Since there may be dimensional errors and positional deviations between the TO fitting 20 and the square seat 18 during processing and assembly, the floating TO clamping seat 84 can automatically adjust its position according to the actual situation, ensuring better alignment and fit between the square seat 18 and the TO fitting 20 during the pressing process, avoiding assembly difficulties or damage caused by positional deviations. Furthermore, during pressing, the floating TO clamping seat 84 relative to the TO positioning seat 81 can move downwards to buffer some of the pressure, preventing the fitting or square seat from deforming, cracking, or damaging its surface due to excessive impact, thus protecting the integrity and performance of the parts.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
