[0023] The lifting and receiving assembly 3 includes a lifting cylinder 31, a snap-on lifting block 32, a first positioning sensor 33, and a spring block 34. The lifting cylinder 31 drives the snap-on lifting block 32 to move up and down. The snap-on lifting block 32 has two snap-on mounting grooves 320 that are opposite to the snap-on discharge port. The outer end of the snap-on mounting groove 320 is provided with a limiting stop part 321. The first positioning sensor 33 is embedded in the two side walls of the snap-on mounting groove 320. The spring block 34 is installed in the snap-on lifting block 32 on both sides of the snap-on mounting groove 320. The bottom of the spring block 34 is installed vertically by spring elasticity.

[0024] The carrier docking assembly 4 includes a docking cylinder 41 and a spring docking carrier 42 that is driven to move up and down by the docking cylinder 41.

After the first positioning sensor 33 senses the product, the blocking cylinder 51 of the blocking component 5 drives the baffle 52 to extend, blocking the subsequent buckle discharge, and the lifting cylinder 31 drives the buckle lifting block 32 to move to the lower position; at the same time, the springs are automatically fed: the spring feeding vibratory plate 2 vibrates and discharges the spring 02, which is then conveyed to the spring pair. In the spring mounting slot of the carrier 42, after the second positioning sensor 43 senses the product, the pressing cylinder 61 of the pressing assembly 6 drives the pressing block 62 to move down and press the spring 02. The docking cylinder 41 drives the spring to dock with the carrier 42 to move down and make room. Assembly: The horizontal moving cylinder 72 and the vertical moving cylinder 73 of the assembly device 7 are linked. The spring clamping assembly 75 clamps the two springs 02 and moves them to be installed on the buckle 01. The spring clamping assembly 75 is released, and the spring ejection assembly 76 extends to further press and install, ensuring that the assembly is in place.
