A screw conveying track is provided in the magazine 21, and the pre-assembled workpieces are moved up along the screw conveying track from the bottom thereof step by the first excitation unit 22 (which is fully disclosed and described in detail in the prior art, and therefore not shown or described in further detail). The horizontal feeding section 3 includes a feeding rail 31 and a second excitation unit 32. The second excitation unit 32 is disposed just below the feeding rail 31. The material conveying groove 311 is formed in the length direction of the material conveying rail 31, and the pre-assembled workpiece is pushed to translate under the action of the second vibration excitation unit 32, so that continuous material supply to the carrying module 4 is realized. It should be emphasized that, the horizontal feeding portion 3 is additionally provided with a leveling portion 33, which is disposed directly below the second excitation unit 32 (as shown in fig. 2) and is used for ensuring the levelness of the feeding rail 31 itself. Therefore, the levelness of the material conveying rail 31 can be adjusted by the leveling part 33 according to actual conditions, so as to ensure the alignment accuracy of the material conveying rail with the upstream spiral ascending feeding part 2 and the downstream conveying module 4, and further ensure the smooth proceeding of the feeding process of the pre-assembled workpiece.

As a further refinement of the structure of the feeding mechanism for conveniently adjusting the levelness of the horizontal feeding portion, the leveling portion 33 is preferably designed according to the following scheme: the leveling part 33 includes a leveling plate 331 and a first adjusting bolt assembly 332. The leveling plate 331 is fixed directly below the second excitation unit 32. The first adjusting bolt assembly 332 includes a first adjusting bolt 3321, a first abutting nut 3322 and a first locking nut 3323, wherein one end of the first adjusting bolt 3321 is vertically fixed on the upper surface of the base platform 1, and the other end thereof penetrates through the leveling plate 331. The first locking nut 3323 and the first leaning nut 3322 are sleeved on the adjusting bolt 3321 and are respectively disposed on the upper and lower sides of the leveling plate 331 (as shown in fig. 2 and 3). In the actual operation process, when the inclination of the feeding track 31 needs to be adjusted, the first locking nut 3323 is firstly loosened, then the first abutting nut 3322 is rotated to move along the first adjusting bolt 3321 in the up-down direction until the self inclination of the leveling plate 331 is adjusted to the proper position, so as to ensure that the horizontal feeding unit 3 has the correct relative position with respect to the spiral ascending feeding unit 2 and the carrying module 4, and then the first locking nut 3323 is tightened in time.
