In order to reduce bacterial infection and speed up assembly efficiency, mechanical equipment is generally used for automatic assembly.

At the same time, the patent does not have the assembly of the pump nozzle and the connecting pipe, and cannot automatically complete the assembly of the entire infusion set parts. This patent uses glue to internally glue the parts of the infusion set that need to be glued, which easily leads to uneven glue application and cannot guarantee the quality of glue packaging. In addition, many processes of this patent are unreasonable, which affects the assembly efficiency and the quality of the infusion set.

The Chinese patent also discloses an assembling device for other parts of the infusion set. Chinese patent application number: 201210284180.1 discloses a gas leak detection device between the needle seat of the infusion set and the infusion tube. Chinese patent application number: 2013107553260 proposes an assembly device for a medical catheter and a liquid stop clip. Chinese Patent Application No.: 201410036583.3 discloses a method and device for gluing a medical plastic needle filter cover. However, these assembly devices can only complete the assembly of one component, and the degree of assembly automation is not high.

Chinese Patent Application No. 201310505124.0 discloses an automatic assembly process of an infusion set. The latex tube is placed on the second conveying platform, and then it is arranged in an orderly manner through the second conveying platform and then transported to the fifth station, and the assembly fixture is conveyed through the assembly track. To the fifth station, the latex tube is clamped by the assembly manipulator to face the joint, the parts to be assembled are coated with glue by the gluing mechanism, and the inner end of the latex tube is sleeved on the joint by moving the assembly manipulator.

The drip hopper, the trident and the rubber cap are placed in their respective feeders, and each feeder arranges the raw materials in it in an orderly manner. Arranged on their respective conveying tracks; the drip hoppers on the conveying track are sequentially sent to the conveying mechanism of circular conveying, and the drip hoppers are fixed by a clamp and then conveyed to the next station. Carry out gluing; when the drip hopper after gluing is transferred to the conveying track equipped with three prongs, the three prongs are sent to the conveying mechanism, and the three prongs are inserted into the drip hopper conveyed to the station by the manipulator. Since the components of the infusion set are plastic products, it is necessary to strictly control the clamping force when using the manipulator to clamp the infusion set components. If the force is too small, the infusion set components cannot be effectively clamped. In addition, the components of the infusion set are small and irregular in shape, and the control precision of the manipulator is relatively high, resulting in a complex assembly process and poor assembly effect. In view of the above-mentioned defects in the current prior art, it is necessary to carry out research and development to solve the defects in the prior art.

The conveyor belt mechanism 8 drives When the catheter is translated, the liquid stopper feeding mechanism 3 assembles the liquid stopper to one end of the catheter on the conveyor belt mechanism 8. After the assembly is completed, the conveyor belt mechanism 8 drives the catheter to continue to translate. Further, the connecting pipe feeding mechanism 4 assembles the connecting pipe to the other end of the conduit. After the assembly is completed, the conveyor belt mechanism 8 drives the conduit to continue to translate. Further, the plug-in detection mechanism 12 detects the plug-in length of the connecting pipe and the catheter, and the unqualified catheter is discarded, and the qualified catheter continues to translate. Then, the vibration plate 521 of the female needle base feeding mechanism 5 vibrates so that the female needle bases are effectively arranged, and then the female needle bases enter the sliding grooves 5221, and the sliding plate 522 vibrates to make the female needle bases slide in the sliding grooves 5221. When the female needle base hits the needle stopper assembly 523, the stopper needle of the needle stopper assembly 523 retracts, the female needle base slides from the sliding groove 5221 into the receiving through groove 5321, the stopper needle extends, and waits for the next group of female needle bases to enter the receiving slot. Through slot 5321. When the detection assembly 5322 detects that there is a female needle base in each of the receiving through grooves 5321, the transfer driving source 535 drives the rotating plate 532 to rotate, so that the port of the receiving through groove 5321 is upward, so that the port is connected to the female needle base of the reclaiming mechanism 54.
