Description

Technical Field

[0001] This invention relates to the field of dialyzer manufacturing, and more particularly to a limiting bundle assembly mechanism for dialyzers and its assembly method. Background Technology

[0002] A dialyzer is a filtration device that transfers waste products, excess water, and electrolytes from the blood into dialysate, working in the same way as a glomerulus. Existing dialyzers mainly consist of an outer shell, a rubber gasket, a sealing layer, and internal fiber bundles. The manufacturing process involves laser printing of the outer shell, insertion of the fiber bundles, and heat sealing. The fiber bundle insertion step requires manual removal of the dialyzer shell from the production line, insertion of the fiber bundles, and return to the conveyor mechanism, resulting in low automation. The process of retrieving and reloading materials also consumes time, impacting production efficiency. Furthermore, manual assembly cannot fully meet the positional accuracy required for fiber bundle installation, thus affecting subsequent processing steps. Summary of the Invention

[0003] The purpose of this invention is to provide a limiting bundle assembly mechanism and method for a dialyzer. This invention can automatically assemble the bundles of the dialyzer housing, improving processing efficiency, and also features high assembly precision.

[0004] The technical solution of the present invention: A limiting bundle assembly mechanism for a dialyzer includes a frame body, a conveyor belt on the frame body, and a material picking component and a material discharging component on both sides of the conveyor belt; the material discharging component includes a bundle feeding box disposed on the frame body, a movable seat at the discharge end of the bundle feeding box, and a fixed seat above the movable seat, the fixed seat and the movable seat closing to form a bundle positioning cavity; the material picking component includes a first movable seat that moves laterally toward the discharging component, a top material rod on the first movable seat, and a top material plate corresponding to the bundle positioning cavity at the end of the top material rod; a second movable seat that moves laterally toward the discharging component on the first movable seat, an outer sleeve sleeved on the second movable seat and a gripper at the end of the outer sleeve; the fixed seat is horizontal and collinear with the axis of the top material rod.

[0005] In the aforementioned limiting bundle assembly mechanism for a dialyzer, the bundle feed box is provided with a stacking ramp, and a single bundle outlet corresponding to the lower end of the stacking ramp is provided on one side of the lower end of the bundle feed box.

[0006] In the aforementioned limiting bundle assembly mechanism for a dialyzer, the movable seat corresponds to the single bundle outlet, and the widths of both the fixed seat and the movable seat are smaller than the width of the single bundle outlet.

[0007] In the aforementioned limiting bundle assembly mechanism for a dialyzer, a feeding plate is provided below the discharge end of the bundle feed box, and a feeding disc driven by a motor is provided above the feeding plate. The feeding disc is provided with uniformly distributed clamping grooves.

[0008] In the aforementioned limiting bundle assembly mechanism for a dialyzer, the gripper includes an inner sleeve sleeved between the top feed rod and the outer sleeve, the end of the inner sleeve is provided with a drive groove, and a push-pull cylinder connected to the inner sleeve is provided on the second moving seat; the end of the outer sleeve is provided with a cylindrical insert, the outer side of the insert is provided with a ring-shaped uniformly distributed mounting groove, the mounting groove is provided with a rotatably connected claw body, and the rotatable connection end of the claw body is provided with a lever that engages with the drive groove.

[0009] In the aforementioned limiting bundle assembly mechanism for a dialyzer, the outer diameter of the insert is smaller than the outer diameter of the top plate, and the outer diameter of the annular ring enclosed after the claw rotates out is larger than the outer diameter of the top plate.

[0010] In the aforementioned limiting bundle assembly mechanism for a dialyzer, both the fixed seat and the movable seat are equipped with ion blowers on their sides.

[0011] In the aforementioned limiting bundle assembly mechanism for a dialyzer, the conveyor belt is provided with limiting claws.

[0012] In the aforementioned limiting bundle assembly mechanism for a dialyzer, a vacuum suction cup is provided on the movable seat.

[0013] The aforementioned assembly method for a limiting bundle assembly mechanism for a dialyzer involves the following steps: The bundle of fibers with a protective film enters from the discharge side of the bundle feed box onto the movable seat. The movable seat moves upward and closes with the fixed seat to form a bundle positioning cavity, achieving wrapping and limiting. At this time, the axis of the bundle positioning cavity, the axis of the dialyzer housing cavity on the conveyor belt, and the top material rod are aligned. The first movable seat starts, driving the top material plate of the top material rod through the dialyzer housing cavity to the end of the bundle of fibers with the protective film and inserting it into the protective film. The second movable seat moves, driving the outer sleeve to the end of the protective film. After the protective film is gripped by the grippers, the first and second movable seats move back synchronously, and the bundle of fibers is pulled into the dialyzer housing along with the protective film. Subsequently, the first movable seat remains fixed, causing the top material plate to block the bundle of fibers, and the second movable seat continues to move back, driving the protective film to be extracted separately from the dialyzer housing, completing the assembly of the bundle of fibers.

[0014] Compared to existing technologies, the bundled filaments with protective films are fed into the bundled filament feed box and enter the movable seat from the discharge side. The movable seat moves upward and closes with the fixed seat to form a bundled filament positioning cavity for wrapping and limiting. At this time, the axis of the bundled filament positioning cavity, the axis of the dialyzer shell inner cavity on the conveyor belt, and the top material rod are aligned. The first movable seat starts, driving the top material plate of the top material rod to pass through the dialyzer shell inner cavity to the end of the bundled filaments with protective films and insert into the protective film. The second movable seat moves, driving the outer sleeve to the end of the protective film. After the protective film is gripped by the grippers, the first movable seat and the second movable seat... The two moving seats move back synchronously, pulling the filament bundle along with the protective membrane into the dialyzer housing. The first moving seat then remains fixed, ensuring the top plate effectively blocks the filament bundle. The second moving seat continues to move back, pulling the protective membrane separately out of the dialyzer housing, completing the filament bundle assembly. All components are then reset for filament assembly in the next dialyzer housing. The entire process is automated, requiring no human intervention, reducing the need for material removal and replacement from the housing, and improving processing efficiency. Simultaneously, the movable top plate's blocking and the movable gripper's grasping mechanism ensure precise filament positioning and excellent assembly reliability. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example: A limiting bundle assembly mechanism for a dialyzer, as shown in the attached figure. Figure 1 As shown, the device includes a frame 1, on which a conveyor belt 2 is mounted. Limiting claws are mounted on the conveyor belt, and these claws are symmetrically arranged Y-shaped frames. The top slots are used to limit the dialyzer housing. Simultaneously, the outer side of the frame fits against the inner side of the protruding edge of the dialyzer housing, allowing the dialyzer housing to be removed only vertically. During assembly, lateral forces cannot move it. Two sets of material-picking components 3 and two sets of material-discharging components 4 are mounted on both sides of the conveyor belt 2. The material-picking and discharging components correspond one-to-one, enabling simultaneous assembly at multiple stations and improving efficiency. (See attached diagram.) Figure 2 and attached Figure 3 As shown, the feeding component 4 includes a bundle feeding box 5 mounted on the frame body 1. The width of the bundle feeding box is consistent with the width of the bundle with protective film. The discharge end of the bundle feeding box 5 is equipped with a movable seat 6 driven by a vertically movable motor. A fixed seat 7 is mounted above the movable seat 6. The fixed seat 7 and the movable seat 6 close to form a cylindrical bundle positioning cavity 8. (See attached diagram) Figure 6 As shown, the material receiving component 3 includes a first movable seat 9 driven laterally by a motor to one side of the material dispensing component. A top material rod 10 is mounted on the first movable seat 9, and a circular top material plate 11 corresponding to the bundle positioning cavity 8 is fixedly connected to the end of the top material rod 10. A second movable seat 12, driven laterally by a motor to one side of the material dispensing component, is mounted on the first movable seat 9. An outer sleeve 13 is sleeved on and movably connected to the top material rod 10, and a gripper 14 is mounted at the end of the outer sleeve 13. The fixed seat 7 is horizontal and collinear with the axis of the top material rod 10. The bundle feeding box 5 contains… A fixed stacking ramp 27 is provided. A single bundle of filaments outlet 28, corresponding to the lower end of the stacking ramp 27, is opened on one side of the lower end of the filament feed box 5. After being fed in, the filaments wrapped in a protective film accumulate inside the filament feed box. Under the influence of gravity, they gather at the bottom along the stacking ramp. The filaments at the bottom roll out through the single bundle of filaments outlet 28, achieving stable single-filament discharge. The movable seat 6 corresponds to the single bundle of filaments outlet 28, and the widths of both the fixed seat 7 and the movable seat 6 are smaller than the width of the single bundle of filaments outlet 28, ensuring that the ends of the filaments with protective films can protrude from the filament positioning cavity, facilitating gripping by the material handling component. (See attached...) Figure 4 and attached Figure 5As shown, an inclined feeding plate 29 is installed below the discharge end of the filament feeding box 5. A motor-driven feeding disc 15 is installed above the feeding plate 29. The feeding disc 15 has evenly distributed clamping slots 16, which fit into individual filament bundles with protective films. After a single filament bundle falls out of its discharge port, it enters the clamping slot and is carried along the feeding plate to the movable seat as the feeding disc rotates, ensuring that the filament bundles are fed in an orderly and spaced manner. (See attached diagram) Figure 7 and attached Figure 8 As shown, the gripper 14 includes an inner sleeve 17 sleeved between the top material rod 10 and the outer sleeve 13. The end of the inner sleeve 17 has three evenly distributed annular drive grooves 18. A push-pull cylinder 19 connected to the inner sleeve 17 is mounted on the second moving seat 12. A cylindrical insert 20 is fixed to the end of the outer sleeve 13. An evenly distributed annular mounting groove 21 is opened on the outer side of the insert 20. A rotatably connected gripper body 22 is mounted in the mounting groove 21 via a rotating shaft. A lever 23, which engages with the drive groove 18, is integrally formed at the rotatable connection end of the gripper body 22. The inner sleeve moves within the outer sleeve via the push-pull cylinder, and the movement of the lever 23 is driven by the movement of the drive grooves. This allows the claws to flip over, and after each claw flips outward, it retracts to cooperate with the insert to achieve a gripping effect. The outer diameter of the insert 20 is smaller than the outer diameter of the top plate 11, and the outer diameter of the ring enclosed by the claw 22 after it rotates outward is larger than the outer diameter of the top plate 11, ensuring that the insert can be inserted into the protective film after the claw flips outward. Subsequently, the retracted claw cooperates with the outer wall of the insert to squeeze and grip the edge of the protective film. The sides of the fixed seat 7 and the movable seat 6 are equipped with ion fans 24 to remove static electricity from the unassembled bundles of filaments with protective films. The movable seat 6 is equipped with a vacuum suction cup 26, which adsorbs and fixes the protective film of the bundle of filaments before the bundle of filaments positioning cavity is formed, preventing displacement.

[0019] Working principle: After the bundled filaments with protective films are fed into the bundled filament feed box 5, they gather at the bottom along the stacking ramp 27 inside the box and fall out through the single bundled filament outlet 28, landing in the clamping groove 16 of the feeding tray 15 above the feeding plate 29 below the discharge end of the bundled filament feed box 5. The feeding tray 15 is driven by a motor to rotate, conveying the bundled filaments to the movable seat 6 in an orderly manner. The vacuum suction cup 26 on the movable seat 6 adsorbs and fixes the bundled filaments to prevent them from shifting. Subsequently, the movable seat 6 moves up and closes with the fixed seat 7 to form the bundled filament positioning cavity 8. At this time, the axis of the bundled filament positioning cavity 8, the axis of the dialyzer shell inner cavity fixed by the limiting claw 25 on the conveyor belt 2, and the axis of the top material rod 10 are kept horizontally collinear. Next, the first moving seat 9 is started, which drives the top material rod 10 and the top material plate 11 at the end of it to pass through the inner cavity of the dialyzer shell. The top material plate 11 is inserted into the protective film of the bundle of fibers. At the same time, the second moving seat 12 is started, which drives the outer sleeve 13 sleeved on the top material rod 10 to move towards the bundle of fibers. The cylindrical insert 20 at the end of the outer sleeve 13 approaches the protective film. At this time, the push-pull cylinder 19 connected to the inner sleeve 17 on the second moving seat 12 drives the inner sleeve 17 to move. The drive groove 18 at the end of the inner sleeve 17 drives the claw body 22 to rotate the connecting block 23, so that the claw body 22 in the mounting groove 21 rotates to surround and grab the protective film. Then, the first moving seat 9 and the second moving seat 12 move back synchronously, and the bundle of filaments is pulled into the dialyzer housing along with the protective membrane. Subsequently, the first moving seat 9 remains fixed, and the top plate 11 continues to block the bundle of filaments to prevent them from moving with the protective membrane. The second moving seat 12 continues to move back, and the claw 22 releases the protective membrane and pulls it out of the dialyzer housing along with the outer sleeve 13, completing the bundle of filament assembly. During this process, the ion blower 24 on the side of the fixed seat 7 and the moving seat 6 continuously removes static electricity from the bundle of filaments. Finally, all components are reset, and the bundle of filament assembly process for the next dialyzer housing begins.
