[0050] In this embodiment, a plurality of retaining springs 100 are arranged in order and conveyed to a dividing mechanism 7 by a feeding mechanism 1, and the dividing mechanism 7 is used to adjust and flip the retaining springs 100 in the feeding mechanism 1; then, the grabbing mechanism 3 grabs the retaining springs 100 in the dividing mechanism 7 and moves them to the feeding mechanism 6; a plurality of metering modules 200 to be assembled are placed in the feeding mechanism 6 in sequence, and the rotating worktable 2 is rotated to the position of the feeding adjustment mechanism 9 and the grabbing mechanism 3, and the cam bearing 69 is driven by the cam pressure plate 94 in the feeding adjustment mechanism 9 to realize the assembly of the drainage tube 101 and the ultrasonic metering component 102, and finally, the retaining spring 100 is pushed to the connection between the drainage tube 101 and the ultrasonic metering component 102 in the feeding mechanism 6 by the pushing mechanism 8, completing the entire automated assembly, which is simple to realize, stable and reliable, and has good assembly consistency.
