Description

Technical Field

[0001] This utility model relates to the field of sealing ring assembly, and in particular to an automatic assembly equipment for sealing rings of infusion bottles. Background Technology

[0002] Normal saline is a sterile medical product. Infusion bottles undergo strict sterilization during the production process to provide a sterile environment for normal saline. Bottles for normal saline can be flexible or rigid. Flex bottles are generally made of plastic, while rigid bottles may be made of thick glass or rigid plastic. For flexible bottles, there is usually no need to install an additional sealing ring because the flexible bottle itself has good flexibility and sealing performance. However, for rigid bottles, especially glass bottles, a sealing ring is usually installed at the bottle mouth or cap to ensure sealing performance. The tight fit between the cap and the bottle mouth alone may not achieve the ideal sealing effect. The sealing ring can make up for this deficiency and enhance the sealing performance.

[0003] A search revealed a Chinese patent publication number: CN213969840U, which discloses a sealing ring assembly device. The device uses left and right moving modules to quickly and accurately drive the connecting plate to move, which in turn drives the transmission plate to move, thereby driving the pushing component to perform material picking or unloading operations. This achieves automated sealing ring assembly operations, eliminating the need for manual intervention during the assembly process and ensuring stable assembly quality.

[0004] In the above technical solution, the left and right moving module drives the pushing component to perform material picking and unloading operations to improve assembly stability. However, during the assembly of the sealing ring, the sealing ring may flip and deform due to its own elasticity. The lack of continuous pushing guidance during assembly leads to a reduction in assembly effect and efficiency. Therefore, an automatic assembly equipment for infusion bottle sealing rings is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an automatic assembly device for infusion bottle sealing rings, which aims to improve the problem that the lack of guiding function in the existing automatic assembly device for infusion bottle sealing rings during the sealing ring assembly operation leads to deformation and flipping of the sealing rings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic assembly device for infusion bottle sealing rings, comprising a device body, a fixed base fixedly connected to the top of the device body, an assembly cylinder fixedly connected to the inner wall of the fixed base, a motor I fixedly connected to the top of the device body via a support, a turntable fixedly connected to the output end of the motor I, a slot being formed through the surface of the turntable, a placement cylinder inserted into the inner wall of the slot, a bracket fixedly connected to the top of the device body, a motor II fixedly connected to the top of the bracket, a rotating frame fixedly connected to the output end of the motor II via a rotating shaft, a drive cylinder fixedly connected to the inner wall of the rotating frame, a lifting frame fixedly connected to the bottom of the drive cylinder, a sleeve fixedly connected to the bottom of the lifting frame, an electric push rod fixedly connected to the inner wall of the lifting frame, a push plate fixedly connected to the output end of the electric push rod, a V-shaped ring fixedly connected to the bottom of the push plate, and an assembly auxiliary component disposed inside the placement cylinder.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of an automatic assembly device for infusion bottle sealing rings, comprising a device body 1, a fixed base 2 fixedly connected to the top of the device body 1, and an assembly cylinder 3 fixedly connected to the inner wall of the fixed base 2. The assembly cylinder 3 is an automatic sealing ring assembly cylinder 3, which has two sets of air passages: a peeling air passage and an expansion air passage. Its surface is provided with expansion fingers and peeling fingers. The expansion fingers are used to open the sealing ring, and the peeling fingers are used to push out the sealing ring. Compressed air is introduced into the expansion air passage, and the sealing ring is opened by the expansion fingers. Simultaneously, compressed air is introduced into the peeling air passage, and the sealing ring is pushed out to the installation position by the peeling fingers. The sealing ring is fed from an external vibrating plate onto the assembly cylinder 3, preparing it for assembly. The vibrating plate and the assembly cylinder 3 are existing publicly available technologies in the field and will not be described in detail here. A motor 4 is fixedly connected to the top of the device body 1 via a support, and a turntable 5 is fixedly connected to the output end of the motor 4. The turntable 5... A slot 6 is cut through the surface, and a placement cylinder 7 is inserted into the inner wall of the slot 6. The placement cylinder 7 is used to hold a hard bottle for holding physiological saline. A bracket 8 is fixedly connected to the top of the device body 1, and a motor 9 is fixedly connected to the top of the bracket 8. The output end of the motor 9 is fixedly connected to a rotating frame 10 via a rotating shaft. A drive cylinder 11 is fixedly connected to the inner wall of the rotating frame 10, and a lifting frame 12 is fixedly connected to the bottom of the drive cylinder 11. A sleeve 13 is fixedly connected to the bottom of the lifting frame 12. An electric push rod 14 is fixedly connected to the inner wall of the lifting frame 12. There are two sets of electric push rods 14, and the two sets of electric push rods 14 are equidistant from left to right with the central axis of the sleeve 13 as the axis of symmetry. A push plate 15 is fixedly connected to the output end of the electric push rod 14. A V-ring 16 is fixedly connected to the bottom of the push plate 15. The V-ring 16 is sleeved on the outer wall of the sleeve 13. After the sealing ring is sleeved on the sleeve 13, it is pushed to the bottle mouth area by the push plate 15. An assembly auxiliary component is provided inside the placement cylinder 7.

[0033] Reference Figures 3-5The assembly auxiliary components include positioning rings 17, which are smaller than semicircular in shape. Each set of placement cylinders 7 has two sets of positioning rings 17, one on the left and one on the right, to provide support for the hard bottle, ensuring that bottles with a diameter smaller than the diameter of the placement cylinder 7 are centered within the cylinder. The upper end of the positioning ring 17, away from the connecting rod 18, has a rounded corner. The side wall of the positioning ring 17 is fixedly connected to the connecting rod 18, and the end of the connecting rod 18 is fixedly connected to a magnetic block 22. The outer wall of the placement cylinder 7 has a groove 20. A magnetic sheet 21 is fixedly connected to the inner wall of the connecting rod 18. The magnetic sheet 21 is sleeved on the outer wall of the connecting rod 18. The side of the magnetic sheet 21 away from the positioning ring 17 is magnetically connected to the outer wall of the magnetic block 22. Due to the magnetic attraction between the magnetic sheet 21 and the magnetic block 22 and the elastic force of the spring 19, the two sets of positioning rings 17 always remain close to each other, thereby ensuring the positioning clamping force. A spring 19 is fixedly connected to the side wall of the positioning ring 17. One end of the spring 19 is fixedly connected to the outer wall of the positioning ring 17, and the other end of the spring 19 is fixedly connected to the inner wall of the placement cylinder 7.

[0034] Reference Figures 2-3 A support frame 25 is fixedly connected to the surface of the bracket 8. An arc-shaped guide rail 23 is fixedly connected to the outer wall of the support frame 25. The arc-shaped guide rail 23 is set at a 90-degree angle with the center point of the rotating shaft connected to the motor 4 as the axis of symmetry. The arc-shaped guide rail 23 is set to remain stable when the rotating frame 10 rotates and switches positions, so that the sleeve 13 moves back and forth stably on the assembly cylinder 3 and the placement cylinder 7. A support block 24 is slidably connected to the outer wall of the arc-shaped guide rail 23. The bottom end of the support block 24 is fixedly connected to the top of the rotating frame 10.

[0035] Working principle: The external feeding device places the infusion bottle into the placement cylinder 7. The two sets of positioning rings 17 are squeezed by the infusion bottle, causing the spring 19 to be compressed. The connecting rod 18 slides out from the groove 20, causing the magnetic block 22 to move away from the magnetic sheet 21. The assembly auxiliary components ensure the stability of the infusion bottle inside the placement cylinder 7. The motor 9 is started to drive the rotating frame 10 to rotate. After the rotating frame 10 moves to the top of the assembly cylinder 3, the motor 9 stops running. At this time, the drive cylinder 11 is opened to drive the lifting frame 12 to descend until the sleeve 13 is directly above the assembly cylinder 3. The peeling fingers of the assembly cylinder 3 push the expanded sealing ring onto the sleeve 13. The drive cylinder 11 rises again. At the same time, the motor 9 starts, driving the rotating frame 10 to reset. When the rotating frame 10 moves, it can drive the support block 24 to slide on the arc-shaped guide rail 23. When the sleeve 13 is in the corresponding position... When the first set of sealing rings is placed above the first set of placement cylinders 7, the drive cylinder 11 controls the sleeve 13 to descend so that it fits over the mouth of the infusion bottle. The two sets of electric push rods 14 are opened at the same time, causing the push plate 15 to descend. The pushing force of the push plate 15 pushes the sealing ring down from the sleeve 13 until it fits over the mouth of the infusion bottle. At the same time as pushing, the V-ring 16 provides a guiding function for the sealing ring. When the sealing ring is pushed by the push plate 15, it can be more accurately aligned with the mouth of the bottle, reducing offset and error and preventing the sealing ring from twisting, flipping or deforming during the pushing process. This ensures that the sealing ring can maintain a good shape and condition and be smoothly pushed onto the mouth of the bottle. After the first set of sealing rings is assembled on the infusion bottle, the above steps are repeated. At the same time, the motor 4 controls the turntable 5 to rotate to a certain extent. The rotation of the turntable 5 drives the unassembled infusion bottle to the assembly position, improving the assembly efficiency and assembly effect.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
