The utility model discloses a fully automatic assembling machine for an infusion set, which belongs to the technical field of medical equipment. The prior art assembling device has a complicated structure and cannot determine whether the assembled infusion set is qualified or not, and cannot automatically complete the assembly of the entire infusion set component .In the utility model, an insertion detection mechanism is installed on the adjacent connecting pipe feeding mechanism above the conveyor belt mechanism to detect the insertion length of the connecting pipe and the catheter, and the adjacent pump connection pipe feeding mechanism is installed above the conveyor belt mechanism to detect infusion The insertion detection mechanism of the insertion length of the device assembly is installed on the upper side of the conveyor belt mechanism adjacent to the female needle base feeding mechanism to detect the completion of the glue assembly of the catheter. The utility model can automatically assemble the infusion set and automatically detect the infusion Whether the device is qualified, the degree of automation is higher, and the structure is more reasonable, which can effectively improve assembly efficiency and save labor costs.
