Abstract
Description
Technical Field
[0001] This invention relates to the field of insulin injector technology, specifically to a feeding device for an insulin syringe assembly. Background Technology
[0002] In recent years, with the improvement of the global economy, the continuous improvement of people's living standards, changes in dietary structure, reduction in labor intensity, increase in average life expectancy, increased stress, and improvements in diabetes detection methods, the prevalence of diabetes, like in other countries around the world, is gradually rising, and the impact of diabetes on global health is becoming increasingly serious. Currently, insulin is the main effective treatment for diabetes. Insulin is a protein that can be destroyed by stomach acid and intestinal proteases when taken orally, causing it to denature and decompose, thus becoming inactive. Therefore, it can currently only be administered by injection, usually subcutaneously.
[0003] Insulin injection tools are syringes specifically designed for injecting insulin. They consist of a needle cap, injection needle, syringe barrel, and injector. When assembling insulin syringe barrels, assembly equipment is needed to quickly assemble individual components on the syringe barrel to improve overall assembly efficiency. However, most syringe processing equipment currently can only perform single-step assembly work and cannot complete the entire assembly process of the syringe barrel, resulting in low overall processing efficiency and poor performance.
[0004] In the prior art, there is a Chinese utility model patent with application number 202021693713.8, authorization publication number CN212892449U, entitled "A Core Rod Feeding Mechanism for an Insulin Injector Assembly Machine," which discloses a core rod feeding mechanism for an insulin injector assembly machine, belonging to the technical field of insulin injector production equipment. The core rod feeding mechanism for an insulin injector assembly machine includes a feeding rack. A sliding plate is provided on the top of the feeding rack, and the other end of the sliding plate is located at the bottom of the inner cavity of the feeding rack. A first conveying plate, a second conveying plate, and a third conveying plate are fixedly connected to the inner side wall of the feeding rack from left to right. A support frame is fixedly connected to the bottom of the feeding rack. A hydraulic cylinder is installed at the bottom of the inner cavity of the support frame. A base is fixedly connected to the top of the hydraulic cylinder, and a first push plate, a second push plate, and a third push plate are connected to the top of the base from left to right.
[0005] In the aforementioned patent, the insulin needle moves laterally upwards during use, facilitating subsequent processing and improving work efficiency. It is known that insulin needles include a needle, and a delivery device is typically used during insulin assembly to organize and transport the needle to a designated position for assembly. In existing technologies, the needle can only be fixed in place during collection and delivery. To remove the needle, the entire storage device must be unlocked, presenting a certain drawback. Summary of the Invention

[0007] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for an insulin syringe assembly, comprising a feeding frame, wherein a carrier for storing the syringe plunger is provided within the feeding frame, the carrier including a support frame slidably connected to the feeding frame, and a protective component for fixing the syringe plunger on the support frame; the feeding frame is provided with a pushing mechanism for driving the support frame to slide, wherein in use, the pushing mechanism drives the support frame to slide, so that the support frame carries multiple sets of syringe plungers to slide, thereby realizing syringe feeding.
[0008] Furthermore, the support frame has multiple sets of mounting slots adapted to the core rods, and each core rod is mounted on the support frame through the corresponding mounting slot.
[0009] Furthermore, the protective component includes multiple sets of protective plates, each of which is slidably connected to the support frame via a corresponding adapter groove; the multiple protective plates are fixedly connected by a connecting plate.

[0011] Furthermore, the triggering element includes multiple sets of trigger rods fixedly connected to the connecting plate. Each set of trigger rods has a wedge-shaped surface on its top, and the bottom of the vertical plate also has an inclined surface. Each wedge-shaped surface intermittently abuts against the inclined surface.
[0012] Furthermore, the vertical plate is slidably connected to the support frame via a positioning component; the positioning component includes a limiting block fixedly connected to both sides of the vertical plate, and a tension spring is provided between the limiting block and the support frame, the tension spring driving the limiting block to slide downward.
[0013] Furthermore, the pushing mechanism includes a push plate slidably connected to the support frame, the push plate being slidably connected to the support frame via an extension member; the feeding frame is provided with a driving member for driving the push plate to slide.

The carrier frame then drives the multiple sets of piston rods to slide on the feeding frame, improving the stability of piston rod installation and making feeding more convenient, reducing the possibility of piston rod confusion. Furthermore, there is no need to unlock multiple sets of piston rods during feeding, greatly improving the working efficiency of the entire feeding device, meeting work needs, and providing better performance.

[0028] 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.
[0029] Please see Figure 1-8 The present invention provides a technical solution: a feeding device for an insulin syringe assembly, including a feeding frame 1, a carrier 4 for storing the syringe rods is provided inside the feeding frame 1, the carrier 4 includes a carrier frame 41 slidably connected to the feeding frame 1, a protective member 5 for fixing the syringe rods is provided on the carrier frame 41, and the syringe rods are fixed; the feeding frame 1 is provided with a pushing mechanism for driving the carrier frame 41 to slide, in use, the pushing mechanism drives the carrier frame 41 to slide so that the carrier frame 41 carries multiple sets of syringe rods to slide, thereby realizing the feeding of syringe rods.
[0030] Specifically, the insulin syringe assembly's feeding device includes a feeding frame 1. Multiple support legs are mounted on the bottom of the feeding frame 1, each with an anti-slip pad to improve stability during operation and meet operational needs. The feeding frame 1 has sufficient space, allowing simultaneous feeding from both sides, further enhancing efficiency and making it suitable for widespread use. The feeding frame 1 includes a support member 4 for storing the syringe plunger, improving stability when the plunger is installed inside. More specifically, the support member 4 includes a support frame 41 slidably connected to the feeding frame 1. The support frame 41 has a raised rib at its bottom, and a positioning groove matching the raised rib is formed inside the feeding frame 1. When the support frame 41 slides inside the feeding frame 1, the raised rib also slides within the feeding frame 1, making it suitable for widespread use. The support frame 41 is equipped with a protective component 5 for fixing the core rod. This secures the core rod, and when the support frame 41 slides, the protective component 5 improves the stability of the core rod during installation, resulting in better performance. The feeding frame 1 is equipped with a pushing mechanism to drive the support frame 41 to slide, facilitating the sliding of the core rod and pushing it to a predetermined position for feeding. In actual use, the pushing mechanism drives the support frame 41 to slide, allowing it to carry multiple sets of core rods for feeding. Therefore, in practical use, multiple sets of core rods are placed on the feeding frame 1, and the pushing mechanism drives the support frame 41 to slide. The support frame 41 then drives the multiple sets of core rods to slide on the feeding frame 1, improving the stability of the core rod installation, facilitating feeding, reducing the possibility of core rod confusion, and eliminating the need to unlock multiple sets of core rods during feeding. This greatly improves the working efficiency of the entire feeding device, meeting work needs and providing better performance.
[0031] In the embodiments provided by the present invention, the support frame 41 is provided with a plurality of mounting slots 42 adapted to the core rod, and each core rod is mounted on the support frame 41 through the corresponding mounting slot 42, which can further improve the stability of the core rod during installation.
[0032] In the embodiments provided by the present invention, the protective component 5 includes multiple sets of protective plates 51, each of which is slidably connected to the bearing frame 41 through a corresponding adapter groove 43; the multiple protective plates 51 are fixedly connected by a connecting plate 52. Therefore, during use, when the core rod is installed into the feeding frame 1 through the mounting groove 42, it is protected by the protective plate 51, which improves the stability of the core rod during installation and meets the working requirements.
[0033] In the embodiments provided by this invention, a limiting member 6 is also provided on the support frame 41. By providing the limiting member 6, the state of multiple sets of core rods can be limited, reducing the possibility of core rod swaying. The limiting member 6 includes a vertical plate 61, which is slidably connected to the support frame 41 via a positioning groove. The support frame 41 is provided with a trigger member for driving the vertical plate 61 to slide upward, thus unlocking the core rods. Therefore, during use, as the pushing mechanism drives the support frame 41 to slide inside the feeding frame 1, it will drive multiple sets of core rods to slide to achieve feeding. After the support frame 41 slides a certain distance, the trigger member drives the vertical plate 61 to slide upward, thereby unlocking the core rods and meeting the operational requirements.
[0034] In the embodiments provided by the present invention, the triggering element includes multiple sets of trigger rods 7 fixedly connected to the connecting plate 52. Each set of trigger rods 7 has a wedge-shaped surface on its top, and the bottom of the vertical plate 61 also has an inclined surface. Each wedge-shaped surface intermittently abuts against the inclined surface. Specifically, in actual use, the pushing mechanism drives the carrying frame 41 to slide inside the feeding frame 1. During the sliding stroke of the carrying frame 41 inside the feeding frame 1, it drives the trigger rods 7 to slide synchronously. After the trigger rods 7 abut against the vertical plate 61, as the carrying frame 41 continues to slide, it drives the vertical plate 61 to slide upwards, thereby unlocking the multiple sets of core rods to meet the working requirements.
[0035] In the embodiments provided by the present invention, the vertical plate 61 is slidably connected to the support frame 41 through a positioning member; the positioning member includes a limiting block 62 fixedly connected to both sides of the vertical plate 61, and a tension spring 63 is provided between the limiting block 62 and the support frame 41. The tension spring 63 drives the limiting block 62 to slide downward. Therefore, during use, the elastic force of the tension spring 63 drives the vertical plate 61 to slide downward, which ensures that the vertical plate 61 always moves downward without the action of external force.
[0036] In the embodiments provided by the present invention, the pushing mechanism includes a push plate 2 slidably connected to the support frame 41, and the push plate 2 is slidably connected to the support frame 41 through an extension member; the feeding frame 1 is provided with a driving member 3 for driving the push plate 2 to slide. Therefore, during use, the push plate 2 is driven to slide inside the feeding frame 1 by the driving member 3. Since the push plate 2 abuts against the support frame 41, the support frame 41 will slide during the sliding stroke of the push plate 2.
[0037] In the embodiments provided by the present invention, the driving component 3 includes a servo motor 31 mounted on the feeding frame 1, a driving gear 32 mounted on the output end of the servo motor 31, and a rack 33 fixedly connected to the push plate 2. The driving gear 32 meshes with the rack 33 to drive the push plate 2 to slide. Therefore, during use, when the servo motor 31 is started, the servo motor 31 is connected to the driving gear 32 through a coupling, thereby driving the driving gear 32 to rotate. When the driving gear 32 rotates, it will drive the rack 33 to slide. During the sliding stroke of the rack 33, it will drive the push plate 2 to slide. The push plate 2 specifically drives the bearing frame 41 to slide inside the feeding frame 1. During the sliding stroke of the bearing frame 41 inside the feeding frame 1, it will drive the trigger rod 7 to slide synchronously. After the trigger rod 7 abuts against the vertical plate 61, as the bearing frame 41 continues to slide, it will drive the vertical plate 61 to slide upward, so that the vertical plate 61 unlocks multiple sets of core rods to meet the working requirements. After the support frame 41 slides a certain distance, that is, after the trigger rod 7 is no longer in contact with the vertical plate 61, the vertical plate 61 is driven to return to its original position downwards by the tension spring 63.
[0038] In the embodiments provided by this invention, a fixing plate 54 is fixedly connected to the support frame 41. A return spring 53 is provided between the fixing plate 54 and the connecting plate 52. The elastic force of the return spring 53 drives multiple sets of protective plates 51 to unlock the core rod. Specifically, in actual use, when the trigger rod 7 on the support frame 41 abuts against the vertical plate 61, it will cause the trigger rod 7 to have a reverse force, which will squeeze the return spring 53. At this time, the core rod is unlocked during the upward sliding stroke of the vertical plate 61, making it convenient for external equipment (such as a robot) to remove the core rod for assembly, that is, to realize the unloading of the core rod, which greatly improves the practicality of the feeding device. After the trigger rod 7 is not abutting against the vertical plate 61, the elastic force of the return spring 53 drives the connecting plate 52 to slide, unlocking multiple sets of core rods, resulting in better performance.
[0039] In the embodiments provided by the present invention, the extension member includes an extension block 9 fixedly connected to the push plate 2, and a groove 8 adapted to the extension block 9 is provided on the feed frame 1, with the extension block 9 slidably connected within the groove 8. Therefore, the stability of the push plate 2 during sliding can be further improved.
[0040] Working principle: When using this feeding device, multiple sets of core rods are first placed inside the bearing frame 41. During operation, the servo motor 31 is started. The servo motor 31 is connected to the drive gear 32 via a coupling, which in turn drives the drive gear 32 to rotate. As the drive gear 32 rotates, it drives the rack 33 to slide. During the sliding stroke of the rack 33, it drives the push plate 2 to slide. The push plate 2 specifically drives the bearing frame 41 to slide inside the feeding frame 1. During the sliding stroke of the bearing frame 41 inside the feeding frame 1, it drives the trigger rod 7 to slide synchronously. After the trigger rod 7 abuts against the vertical plate 61, the continuous sliding of the support frame 41 will cause the vertical plate 61 to slide upward, thereby unlocking multiple sets of core rods to meet the working requirements. During this stroke, when the trigger rod 7 on the support frame 41 abuts against the vertical plate 61, it will cause the trigger rod 7 to exert a reverse force, which will then compress the return spring 53. At this moment, the core rods are unlocked during the upward sliding stroke of the vertical plate 61, making it convenient for external equipment (such as a robot arm) to remove the core rods for assembly, thus realizing the unloading of the core rods and greatly improving the practicality of the feeding device. After the support frame 41 slides a certain distance, that is, when the trigger rod 7 is no longer abutting against the vertical plate 61, the vertical plate 61 is driven downward to return to its original position under the action of the tension spring 63, making it convenient to fix the core rods through the vertical plate 61 to meet the working requirements.
