The following describes the embodiments of the present invention based on its overall structure.

[0025] Reference Figures 1 to 8 In an embodiment of the present invention, a positioning mechanism for assembling an infusion hose of an infusion set includes: a conveyor belt 1, a sleeve plate 2 is placed above the conveyor belt 1, an infusion needle 3 is inserted above the 2, a base plate 4 is provided on the side of the conveyor belt 1, a blanking inclined plate 5 is fixedly provided at one end above the base plate 4, a vertical plate 6 is fixedly provided on one side of the conveyor belt 1, a first fixed block 7 is fixedly provided on one side of the vertical plate 6, a knife cutting groove plate 8 is fixedly provided on the side of the first fixed block 7, a second fixed block 9 is fixedly provided on the other side of the vertical plate 6, a spring 10 is fixedly provided on the inside of the second fixed block 9, a connecting rod 11 is fixedly connected to the side of the spring 10, a cutting knife 12 is fixedly connected to the side of the connecting rod 11, a support column 13 is provided on the other side of the blanking inclined plate 5, a control device 14 is fixedly provided above the support column 13, a telescopic rod 15 is fixedly connected to the side of the control device 14, and the telescopic rod 15 is fixedly connected to one side of the cutting knife 12.

[0026] The above solution is adopted: the conveyor belt 1 is used as the main conveying component, and the connection between the sleeve plate 2 and the infusion needle 3 is coordinated to ensure the initial positioning of the assembly. The design of the blanking inclined plate 5 on the base plate 4 facilitates the blanking of the assembled product.

[0027] A workbench 16 is fixedly provided on the other side of the unloading inclined plate 5, a vertical rod 17 is fixedly provided above the workbench 16, a top plate 18 is fixedly provided above the vertical rod 17, a first slide rail 19 is fixedly provided below the top plate 18, a first pusher 20 is slidably provided below the first slide rail 19, a slide groove 21 is provided on the surface of the workbench 16, a slide rod 22 is fixedly provided on the inner side of the slide groove 21, a push plate 23 is slidably provided on the surface of the slide rod 22, a sleeve plate pusher 24 is fixedly provided below the push plate 23, a second slide rail 25 is slidably provided below the sleeve plate pusher 24, a base 26 is fixedly provided below the second slide rail 25, a side bottom plate 27 is fixedly provided on the side of the base 26, a side pusher 28 is fixedly provided above the side bottom plate 27, and a sleeve plate collection box 29 is provided on the other side of the base plate 4.

[0028] The above solution: the combination of the vertical rod 17, the top plate 18 and the first slide rail 19 provides a stable moving track for the first pusher 20, ensuring the accurate docking of the infusion needle 3 and the hose.

[0029] A hose lifting device 30 is fixedly installed in the middle position above the substrate 4, a gas injection device 31 is fixedly installed at one end above the substrate 4, and a clamping device 32 is fixedly installed at the other end above the substrate 4. A clamping plate 33 is fixedly connected to the side of the clamping device 32, and a clamping ring 34 is fixedly installed on the side of the clamping plate 33.

[0030] The above solution is adopted: the air injection device 31 injects air into the inside of the hose to keep it in a straight state, which facilitates the fixation of the clamping ring 34 and the subsequent docking work. The design of the clamping device 32 and its clamping plate 33 and clamping ring 34 ensures the stability and accuracy of the hose during the docking process.

[0031] Multiple sets of plates 2 and infusion needles 3 are placed above the conveyor belt 1. The plates 2 start to fix the infusion needles 3, which is convenient for the subsequent positioning and installation. The multiple sets of plates 2 are adhered together. When the plates 2 pass through the vertical plate 6, the control device 14 drives the telescopic rod 15 to drive the cutting knife 12 to perform cutting work, and separates the adhered plates 2, so that the plates 2 slide onto the workbench 16 in groups through the unloading inclined plate 5. When a group of plates 2 slides onto the workbench 16, the conveyor belt 1 stops rotating and waits for the positioning and installation to be completed before carrying out the transmission work.

[0032] The above solution is adopted: through the precise control of the control device 14, the automatic cutting and separation of the sets of plates 2 is realized, ensuring that each set of sets of plates 2 can independently slide onto the workbench 16 through the unloading inclined plate 5. The design of this process greatly improves the degree of automation and efficiency of assembly.

[0033] The sleeve plate 2 is pushed to the installation area of the workbench 16 by the side pusher 28. The first pusher 20 pushes the first slide rail 19 to dock the infusion needle 3 with the hose. After the docking is stable, the docked infusion hose is removed. The sleeve plate pusher 24 drives the push plate 23 to push the discarded sleeve plate 2 into the sleeve plate collection box 29.

[0034] By adopting the above solution, the design of the plate pusher 24 and the second slide rail 25 realizes the automatic collection and cleaning of the discarded plate 2, thereby improving the production efficiency and the cleanliness of the working environment.

[0035] The hose lifting device 30 lifts the hose and plugs the hose into the side of the gas injection device 31. The gas injection device 31 blows the hose straight to facilitate the fixing of the clamping ring 34 and the subsequent docking work.

[0036] With the above solution, the hose is lifted and straightened by the combined action of the hose lifting device 30 and the air injection device 31. The design of this step not only improves the accuracy of assembly, but also ensures the stability and reliability of the hose during the docking process.

[0037] The working principle of the present invention is as follows: first, multiple sets of sleeves 2 and infusion needles 3 are placed on the conveyor belt 1, and the sleeves 2 play a fixing role for the infusion needles 3, which is convenient for subsequent positioning and installation. When these sleeves 2 move with the conveyor belt 1 to the vicinity of the vertical plate 6, the control device 14 drives the cutting knife 12 through the telescopic rod 15 to perform cutting work. With the assistance of the spring 10 and the connecting rod 11, the cutting knife 12 accurately cuts off the sleeves 2 that are stuck together, ensuring that each set of sleeves 2 can slide down to the workbench 16 through the blanking inclined plate 5 alone. Once a group of sleeves 2 slides down to the workbench 16, the conveyor belt 1 stops rotating and waits for the group of sleeves 2 to complete the positioning and installation. At this time, the side pusher 28 pushes the sleeve 2 to the installation area of the workbench 16 through the side bottom plate 27. At the same time, the hose lifting device 30 lifts the hose and plugs it into the side of the gas injection device 31 On the other hand, the air injection device 31 blows air into the hose to keep it in a straight state, which is convenient for subsequent clamping and docking work. Subsequently, the first pusher 20, under the guidance of the first slide rail 19, pushes the infusion needle 3 to dock with the hose that has been blown straight. During the docking process, the clamping device 32 and its connected clamping plate 33 and clamping ring 34 are responsible for stably clamping the hose to ensure the accuracy and stability of the docking. After the docking is completed, the assembled infusion hose is removed for the next step of processing. At the same time as the infusion hose is removed, the sleeve pusher 24 drives the push plate 23 under the guidance of the slide bar 22 and the slide groove 21 to push the discarded sleeve 2 into the sleeve collection box 29 to realize centralized treatment of waste. At this point, a complete infusion hose assembly process is completed, and the conveyor belt 1 is started again to carry out the transportation and assembly of the next set of sleeve plates 2 and infusion needles 3.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
