Referring to fig. 14, the clamping mechanism 63 includes a first clamping plate 631 and a second clamping plate 632 which are stacked, and a first pneumatic finger 633 for driving the first clamping plate 631 and the second clamping plate 632 to slide relatively. The first clamping plate 631 is provided with five first clamping grooves 6311 which are arranged at intervals and used for inserting the longitudinal fan blades; the second clamp plate 632 has five second clamp grooves 6321 arranged at intervals and used for inserting the longitudinal fan blades. The first clamping plate 631 and the second clamping plate 632 are arranged with a gap of one clamping groove such that the four first clamping grooves 6311 of the first clamping plate 631 and the four second clamping grooves 6321 of the second clamping plate 632 face each other. The clamping mechanism 63 is driven by the first pneumatic finger 633 to have a clamping state for clamping the longitudinal blade assembly 82 and a releasing state for releasing the longitudinal blade assembly 82.

4. the first robot 6 mounts the longitudinal fan blade assembly 82 to the housing base of the assembly seat 1 at the first press-fitting station 235, so that the six longitudinal fan blades are correspondingly clamped into the limiting grooves 122 of the first convex portion of the assembly seat 1 one by one;

5. the first press-mounting mechanism 3a presses the longitudinal fan blade assembly 82 into the base of the shell, so that the hinged head of the longitudinal fan blade is clamped into the hinged hole 813;

6. after the lifting mechanism at the first press-fitting station 235 is reset, the first conveying unit 2a1 resumes movement, so that the assembly seat 1 moves to the second press-fitting station 236 under the action of the first conveying unit 2a1, the second conveying unit 2a2 and the third conveying unit 2a3, and the lifting mechanism at the second press-fitting station 236 acts, so that the assembly seat 1 at the second press-fitting station 236 is lifted;

7. the second robot 7 places the transverse fan blade component 83 on the shell base on the assembly seat 1;

8. the second press-fitting mechanism 3b presses the transverse fan blade assembly 83 onto the housing base, and presses the first side plate 832 and the second side plate 833 into the first mounting groove 814 and the second mounting groove 815 respectively;

9. the lifting mechanism at the second press-fitting station 236 is reset, and the assembly base 1 is conveyed to the fourth station 234 by the third conveying unit 2a 3;

10. the operator detaches the housing base on the assembly base 1 on which the longitudinal fan blade assembly 82 and the transverse fan blade assembly 83 are mounted from the assembly base 1, and the second transfer mechanism 4b moves the detached assembly base 1 to the first station 231.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
