Description

Technical Field

[0001] The utility model relates to an upper shell pipe assembling device for an infusion set flow rate regulator. Background Art

[0002] Intravenous infusion utilizes the principles of atmospheric pressure and hydrostatic pressure to infuse a large amount of sterile liquids, electrolytes, and drugs into the body through a vein. A disposable infusion set is a common medical consumable for intravenous infusion, which is aseptically processed to establish a channel between the vein and the medicinal solution. A disposable infusion set generally consists of components such as an injection needle, an infusion hose, a medicinal solution filter, a flow rate regulator, a drip chamber, and an air filter connected together.

[0003] The flow rate regulator uses a roller disposed inside the regulator housing to control the size of the liquid flow rate, and can adjust the inflow rate of the medicinal solution according to the needs of different patients. When assembling the flow rate regulator, the regulator housing needs to be installed on the infusion hose, and then the roller is installed inside the regulator housing.

[0004] The Chinese utility model patent with the application number 202320522938.4 discloses an upper shell pipe assembling device for an infusion set flow rate regulator, which includes a frame. A linear material path is provided on the frame, and a material receiving mechanism is connected to the discharge port of the linear material path; a shell taking mechanism is arranged above the material receiving mechanism, and a dislocation mechanism is arranged on the side of the material receiving mechanism. It also includes a pipe aligning mechanism and a pipe lifting mechanism. The pipe aligning mechanism is arranged behind the material receiving mechanism, and the pipe lifting mechanism is arranged behind the pipe aligning mechanism; the pipe aligning mechanism includes an upper alignment mechanism and a lower alignment mechanism that cooperate with each other. The upper alignment mechanism is arranged on the upper part of the frame in a liftable manner, and the lower alignment mechanism is arranged on the lower part of the frame in a liftable manner; the upper alignment mechanism is located between the shell taking mechanism and the pipe lifting mechanism, and the pipe lifting mechanism is arranged on the upper part of the frame in a longitudinally movable manner. Due to the softness of the infusion tube itself, it is necessary to support the end of the infusion tube and the tube body during the assembling process. Although a dislocation mechanism is added in the prior art, during the assembling process of the prior art, the dislocation mechanism only plays a role in fixing the infusion tube and does not have the function of adjusting the position and supporting the infusion tube, resulting in low cooperation degree between the pipe lifting mechanism and the shell taking mechanism, long assembling movement stroke, large occupied space, long production assembling time of the infusion set, and low efficiency. Summary of the Invention

[0005] The purpose of the utility model is to solve the above-mentioned deficiencies of the prior art, and provide an upper shell pipe assembling device for an infusion set flow rate regulator. The technical problem solved by this application is the low cooperation degree between the pipe lifting mechanism and the shell taking mechanism, long assembling movement stroke, large occupied space, long production assembling time of the infusion set, and low efficiency.

[0006] The invention discloses an upper shell tube assembly device for an infusion set flow rate regulating shell, which is arranged on an infusion set assembly production line and comprises a feeding mechanism. A discharge mechanism is arranged at the discharge end of the feeding mechanism. A supporting component is arranged above the discharge mechanism. A material taking mechanism is slidably connected to the supporting component. A tube clamping mechanism is arranged on the side of the material taking mechanism. A tube holding mechanism with the same horizontal height as the tube clamping mechanism is arranged between the tube clamping mechanism and the material taking mechanism. The tube holding mechanism comprises a tube holding part and a first driving mechanism for driving the tube holding part to move horizontally. The first driving mechanism is fixedly connected to the supporting component via a lifting device, and the tube clamping mechanism is linked to the lifting of the tube holding mechanism.

[0007] In the present application, the feeding mechanism transports the flow rate regulating shell to the discharging mechanism, wherein the number of receiving devices in the discharging mechanism is a multiple of the number of discharging channels in the feeding mechanism, and the discharging mechanism can receive a single discharge quantity of flow rate regulating shells multiple times during the lateral movement and receiving process. The flow rate regulating shell in the discharging mechanism is taken out by the picking mechanism and driven to the assembly starting end. At this time, the assembly hole of the flow rate regulating shell in the picking mechanism is consistent with the height of the infusion tube in the tube holding part, and a vertical installation structure is formed between the supporting component and the tube clamping mechanism. The tube clamping mechanism and the tube holding mechanism are horizontally arranged to ensure the accuracy of the infusion tube assembly process, facilitate alignment, achieve accurate assembly, avoid deviation, reduce the damage to the infusion tube caused by deviation during the assembly process, improve assembly efficiency, and effectively reduce the damage rate during the assembly process, thereby improving the assembly yield rate.

[0008] At the same time, the tube holding part in the tube holding mechanism clamps the end of the infusion tube, and drives the infusion tube to move sideways with the tube clamping mechanism as the center, and finally runs to the material picking mechanism, and cooperates with the material picking mechanism to realize the assembly of the infusion tube and the flow rate regulating shell. The tube holding mechanism can move the infusion device to the corresponding assembly position during the movement, and at the same time fix and limit the end of the infusion tube. After the flow rate regulating shell and the infusion tube are plugged and assembled, the tube holding mechanism can be completely or slightly relaxed. Complete relaxation facilitates the plugging of the flow rate regulating shell and the infusion tube. After slight relaxation, the tube holding part can slide back and forth along the infusion tube, and at the same time support the infusion tube. During this process, the movement of the material picking mechanism is not affected, and the tube holding part can move along with the movement direction of the material picking mechanism, thereby reducing the waiting time during the assembly work, speeding up the assembly speed, and improving production efficiency.

[0009] Furthermore, a frame is provided below the feeding mechanism, a transfer platform is installed on the upper surface of the frame, a supporting component is fixed on the transfer platform, the feeding mechanism is fixed on the frame through a direct vibration mechanism, and a supporting component connected to the top of the supporting component is provided above the feeding mechanism.

[0010] In this application, the transfer platform can drive the feeding mechanism to be installed at any position on the frame, facilitating the adjustment of the feeding mechanism at different positions, thus better meeting the usage requirements of different processing and production processes. The supporting components and the supporting parts are detachably installed, with a simple structure, convenient disassembly and assembly, and easy maintenance and replacement. At the same time, feeding and assembly can be combined at the same station, reducing the floor area of the entire upper shell pipe assembly device, improving the working efficiency of the upper shell pipe assembly device, and realizing the high-speed, compound, and intelligent assembly process.

[0011] Further, the pipe clamping mechanism reciprocates horizontally at the horizontal height of the supporting part.

[0012] In this application, the second driving mechanism includes a driving component that controls the horizontal and vertical movement of the material taking mechanism, and also includes a control driving part that controls the grasping of the material taking mechanism, realizing multi-directional adjustment of the material taking mechanism to meet the production needs.

[0013] Further, the feeding mechanism is driven to feed by a linear vibrating mechanism.

[0014] In this application, the auxiliary feeding mechanism efficiently conveys materials, and the adjustment shell reaches the front end of the linear vibration through linear vibration feeding for material distribution and then enters the discharging mechanism.

[0015] Further, the feeding mechanism includes multiple parallel discharging channels, and the discharging mechanism includes a receiving device that cooperates with the discharging ports of the discharging channels to receive materials.

[0016] In this application, the feeding mechanism is composed of multiple discharging channels, which can accommodate multiple materials for simultaneous conveying, improving the feeding efficiency and speed.

[0017] Further, the discharging mechanism is driven by a third driving mechanism and reciprocates horizontally at the discharging port of the feeding mechanism.

[0018] In this application, the discharging mechanism can receive the feeding quantity conveyed by the feeding mechanism in a single conveyance during one movement, and the discharging mechanism can perform multiple horizontal movements to continuously receive materials.

[0019] Further, a photoelectric detection device is installed on the feeding mechanism.

[0020] In this application, the photoelectric detection device detects the material body in the feeding mechanism, which can effectively ensure normal feeding in the feeding channel. When abnormalities or blockage problems occur, they can be immediately detected, reducing the error rate during the assembly process and accelerating the assembly production speed.

[0021] Further, the pipe clamping mechanism includes a pipe clamping part and a control mechanism that drives the pipe clamping part to open and close. The pipe clamping part includes multiple pipe clamps, the pipe holding part includes multiple pipe holding clamps, and the pipe holding clamps and the pipe clamps correspond to each other one by one in the horizontal direction.

[0022] In this application, two different types of clip structures are adopted to enhance the fit between the pipeline and the clip, ensuring sufficient clamping force while improving production efficiency and qualification rate.

[0023] Beneficial effects:

[0024] This device combines multiple mechanisms responsible for feeding, material taking, and assembly, which is innovative. It optimizes the assembly process of the infusion tube and the flow rate adjustment shell, making the device have the advantages of high speed, high efficiency, compounding, and intelligence. The structure is simple, effectively reducing the consumable cost of equipment manufacturing and the floor area of the equipment. At the same time, it reduces the moving time or process steps of materials during the assembly process, greatly improving the production efficiency of the assembly equipment and being suitable for large-scale use.

[0025] This device is provided with a tube holding mechanism for fixing the end position of the infusion tube. The flow rate adjustment shell is driven by a linear vibration mechanism to feed the feeding mechanism, and the flow rate adjustment shell reaches the outlet end of the feeding mechanism for material separation, and then enters the receiving device one by one. Then, the material taking mechanism grabs the flow rate adjustment shells in the receiving device at the same time. At the same time, the tube clamping mechanism and the tube holding mechanism grab the infusion tube, and the assembly work is completed through the mutual cooperation of the tube clamping mechanism, the tube holding mechanism, and the material taking mechanism. The tube holding mechanism can guide and fix the end of the infusion tube, and at the same time avoid the bending of the infusion tube during assembly, strengthening the overall hardness of the infusion tube, making the assembly process smoother, achieving non-damage to the tube under the premise of high-efficiency assembly, improving production efficiency and assembly qualification rate. The tube clamping clip is a flat clip structure, and the tube holding clip is an arc-shaped holding clip. Two sets of clips are used to grab the infusion tube. Using two sets of clips to grab the infusion tube can ensure sufficient clamping force, and the arc-shaped holding clip ensures the axial position at the front end of the infusion tube assembly, improving the assembly efficiency and qualification rate.

The embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0032] Embodiment 1

[0033] As Figures 1 to 4 shown, as a specific implementation mode of the present utility model, an upper shell tube assembling device of an infusion set flow rate regulator includes a feeding mechanism 1, a photoelectric detection device 2, a material taking mechanism 3, a pipe clamping mechanism 4, a pipe holding mechanism 5, a pipe holding part 6, a first driving mechanism 7, a frame 8, a discharging mechanism 9, a third driving mechanism 10, a transfer platform 11, a supporting component 12, a supporting member 13, a second driving mechanism 14, a discharging channel 15, a material receiving device 16, a linear vibration mechanism 17, a pipe clamping clip 18, and a pipe holding clip 19.

A material taking mechanism 3 is slidably connected to the supporting member 13. A pipe clamping mechanism 4 is arranged on the side of the material taking mechanism 3. A pipe holding mechanism 5 with the same horizontal height is arranged between the pipe clamping mechanism 4 and the material taking mechanism 3. The pipe holding mechanism 5 includes a pipe holding part 6 and a first driving mechanism 7 for driving the horizontal movement of the pipe holding part 6. The first driving mechanism 7 is fixedly connected to the supporting member 13 through a lifting device.

Among them, the first driving mechanism 7 and the second driving mechanism 14 can be a linear motor, a servo screw structure, a pneumatic driving cylinder, a hydraulic driving cylinder, etc.

[0035] The feeding mechanism 1 conveys the flow rate regulating shell to the discharging mechanism 9, wherein the number of the receiving devices 16 in the discharging mechanism 9 is a multiple of the number of the discharging channels 15 in the feeding mechanism 1. The discharging mechanism 9 can receive the flow rate regulating shells of a single discharge quantity multiple times during the lateral movement and acceptance process. The flow rate regulating shell in the discharging mechanism 9 is taken out by the taking mechanism 3 and driven to run to the assembly starting end. At this time, the assembly hole of the flow rate regulating shell in the taking mechanism 3 is consistent with the height of the infusion tube in the tube holding part 6, and a vertical installation structure is formed between the supporting component 13 and the tube clamping mechanism 4. The tube clamping mechanism 4 and the tube holding mechanism 5 are arranged horizontally to ensure the accuracy of the infusion tube assembly process.

After the flow rate regulating shell and the infusion tube are plugged and assembled, the tube holding mechanism 5 can be Completely relax or slightly relax. Completely relaxing facilitates the connection between the flow rate regulating shell and the infusion tube. After slightly relaxing, the tube holding part 6 can slide back and forth along the infusion tube, and at the same time support the infusion tube. In this process, the movement of the material taking mechanism 3 is not affected, which reduces the waiting time in the assembly process, speeds up the assembly speed, and improves production efficiency. A frame 8 is provided below the feeding mechanism 1, and a transfer platform 11 is installed on the upper surface of the frame 8. A supporting component 12 is fixed on the transfer platform 11. The feeding mechanism 1 is fixedly arranged above the transfer platform 11 through a straight vibration mechanism 17. A supporting component 13 connected to the top of the supporting component 12 is provided above the feeding mechanism 1. The platform 11 can drive the feeding mechanism 1 to be installed at any position on the frame 8, which is convenient for the feeding mechanism 1 to adjust different positions, so as to better meet the use of different processing and production processes. The supporting component 12 and the supporting component 13 are detachable and have a simple structure, convenient disassembly and assembly, and convenient maintenance and replacement. At the same time, the feeding and assembly can be combined on the same workstation, reducing the footprint of the entire upper shell pipe assembly device, improving the working efficiency of the upper shell pipe assembly device, and realizing the high-speed, composite and intelligent assembly process. A plurality of rollers are installed on the lower surface of the frame 8, which can assist the staff in moving the frame 8, and are more suitable for large-scale use within the factory and are easy to operate.

[0036] The pipe holding mechanism 5 reciprocates at the horizontal height of the supporting component 13. The second driving mechanism 14 includes a driving component for controlling the lateral and vertical movements of the material picking mechanism 3, and also includes a control driving component for controlling the grabbing of the material picking mechanism 3, thereby realizing multi-directional adjustment of the material picking mechanism 3 to meet production needs.

[0037] The feeding mechanism 1 is driven by a linear vibration mechanism 17 to feed materials, assisting the feeding mechanism 1 to efficiently convey materials. The adjusting shell reaches the front end of the linear vibration through linear vibration feeding for material distribution and then enters the discharging mechanism 9.

[0038] The feeding mechanism 1 includes a plurality of discharge channels 15 arranged in parallel. The discharging mechanism 9 includes a receiving device 16 that cooperates with the discharge ports of the discharge channels 15 to receive materials. The feeding mechanism 1 is composed of a plurality of discharge channels 15 and can accommodate multiple materials for simultaneous conveyance, improving the feeding efficiency and speed.

[0039] The discharging mechanism 9 is driven by a third driving mechanism 10 and reciprocates horizontally at the discharge port of the feeding mechanism 1. The discharging mechanism 9 can receive the quantity of materials supplied by the feeding mechanism 1 in a single conveyance during one movement, and the discharging mechanism 9 can move horizontally multiple times to continuously receive materials.

[0040] An optoelectronic detection device 2 is installed on the feeding mechanism 1. The optoelectronic detection device 2 detects the material body in the feeding mechanism 1, which can effectively ensure normal feeding in the feeding channel. When abnormalities or blockage problems occur, they can be detected immediately, reducing the error rate during the assembly process and accelerating the assembly production speed.

The pipe clamping part includes a plurality of pipe clamps 18, and the pipe holding part 6 includes a plurality of pipe holders 19. The pipe holders 19 and the pipe clamps 18 correspond to each other one by one in the horizontal direction. By adopting two different types of clip structures, the fit between the pipe and the clip is enhanced, ensuring sufficient clamping force while improving production efficiency and qualification rate. The internal shapes of the pipe holders 19 and the pipe clamps 18 are designed to be similar to the shape of the flow rate adjusting shell, aiming to better grip the flow rate adjusting shell and avoid damage to the flow rate adjusting shell by the pipe holders 19 or the pipe clamps 18, improving the qualified product rate during the assembly process. The pipe holders 19 not only have a receiving effect but also can increase the hardness of the infusion tube during the assembly process, preventing the infusion tube from bending slightly, making the entire assembly process smoother. At the same time, there is no need to wait for the pipe holders 19 to retract, and it can achieve follow-up movement, with convenient assembly and high efficiency.

[0042] In use, the flow rate adjusting shell is fed through the feeding mechanism 1. The feeding mechanism 1 is driven by the linear vibration mechanism 17 for efficient feeding. The structure is simple and easy to use. The material reaches the discharge end of the feeding mechanism 1 and then falls into the discharging mechanism 9 waiting for the picking mechanism 3 to pick it up. Then, the picking mechanism 3 grabs the corresponding number of flow rate adjusting shells at the same time and drives them to the starting end of assembly. At the same time, the pipe clamping mechanism 4 clamps the infusion tube. The tube holding part 6 in the tube holding mechanism 5 clamps the end of the infusion tube and drives the infusion tube to move laterally with the pipe clamping mechanism 4 as the center until the assembly hole of the flow rate adjusting shell in the picking mechanism 3 is at the same height as the infusion tube in the tube holding part 6. Through the cooperation of the picking mechanism 3, the tube holding mechanism 5 and the pipe clamping mechanism 4, the assembly of the adjusting shell is completed. After the assembly is completed, the next process is entered.
