The to-be-mounted spring 21 can be stably limited in the material receiving frame 2; The horizontal forward and backward sliding of the electric push-pull rod 5 can drive the horizontal forward and backward sliding of the material pushing frame 41, that is, the horizontal forward and backward sliding of the material pushing mechanism 4; When the driven gear 431 passes through the first rack 121 and the second rack 122, the driven gear 431 can rotate, that is, the threaded rod 43 rotates. When the electric push-pull rod 5 drives the material pushing mechanism 4 to slide forward horizontally, the driven gear 431 rotates forward, that is, the threaded rod 43 rotates forward. The forward rotation of the threaded rod 43 drives the vertical downward movement of the material pushing plate 42 in the vertical rail 411. When the electric push-pull rod 5 drives the material pushing mechanism 4 to slide backward horizontally, the driven gear 431 reverses, that is, the threaded rod 43 reverses; The horizontal forward and backward sliding of the electric push-pull rod 5 drives the material pushing mechanism 4 to slide forward, passes through the second rack 122, and the driven gear 431 rotates forward. The threaded rod 43 drives the vertical downward movement of the material pushing plate 42 in the vertical rail 411, and finally makes the push rod 421 descend to the same height of the avoiding groove 201.

The push rod 421 supports the material receiving frame 2 to keep the material receiving frame 2 horizontally pushed out of the material loading box 1. Then the upper hook of the to-be-mounted spring 21 in the material receiving frame 2 is hung on the upper mounting position of the accordion key. At this time, the driven gear 431 passes through the first rack 121, the electric push-pull rod 5 continues to drive the material pushing mechanism 4 to slide forward horizontally, the threaded rod 43 drives the material pushing plate 42 to continue to vertically descend in the vertical rail 411, so that the push rod 421 continues to descend and drives the to-be-mounted spring 21 to stretch, until the bottom hook of the to-be-mounted spring 21 is hung on the lower mounting position of the accordion key, and the to-be-mounted spring 21 is assembled; Then the electric push-pull rod 5 drives the pushing mechanism 4 to slide horizontally backward, the threaded rod 43 drives the pushing plate 42 to rise vertically in the vertical rail 411, and the push rod 421 reaches the same height at the top of the next layer of the supporting frame 2. Then the electric push-pull rod 5 drives the pushing mechanism 4 to continue to slide horizontally backward, at this time, the driven gear 431 is between the second rack 122 and the first rack 121, and the driven gear 431 does not rotate. The pushing frame 41 presses the next layer of the supporting frame 2. When the driven gear 431 engages with the second rack 122, the pushing frame 41 exits the loading magazine 1. At this time, the push rod 421 presses the next layer of the supporting frame 2. The electric push-pull rod 5 drives the pushing mechanism 4 to continue to slide horizontally backward. The threaded rod 43 drives the pushing plate 42 to rise vertically in the vertical rail 411. The next layer of the supporting frame 2 rises linearly with the push rod 421. Then, as the electric push-pull rod 5 drives the pushing mechanism 4 to slide horizontally backward, the push rod 421 gradually exits the loading magazine 1. Finally, the next layer of the supporting frame 2 is separated from the push rod 421 through the slope on the front side of the push rod 421, realizing the stable upward movement of the next layer of the supporting frame 2 to the top of the loading magazine 1, ensuring the stable upward movement of the supporting frame 2, preventing the waiting spring 21 in the supporting frame 2 from being displaced or falling from the supporting frame 2 due to the sudden upward movement of the supporting frame 2, thereby affecting the assembly quality of the waiting spring 21.
