In addition, as shown in fig. 1 to 20, a blocking mechanism for blocking the corresponding follower tool from being continuously conveyed and an anti-rollback mechanism for preventing the corresponding follower tool from being rollback are provided at each station of the rotor assembly line 200 and/or the assembly line 300. Both the blocking mechanism and the anti-rollback mechanism may employ conventional mechanisms, which are not described in detail herein.
The present invention has been described in detail with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments, and those skilled in the art can make various modifications to the present invention according to the prior art, which are all within the scope of the present invention.
