In step S02, the shaft body 4 is passed through the roller group 3. Here, the shaft body 4 is placed on the support member 225, and then the motor 224 drives the lead screw 223 so that the body 222 can be brought toward the guide shaft body 121 toward the clamp device 21 by the lead screw 223. The shaft body 4 is passed through the roller group 3.

In step S03, the first actuation mechanism 216 pushes the first link 214 and drives the second clamp body 213 toward the first clamp body 212, so that the second clamp body 213 and the first clamp body 212 clamp the roller set 122. , the roller set 3 is fixed to the shaft body 4. In addition, in the clamping step S3, when the second link 215 is pierced and fixed to the second through hole 2133 of the second clamp body 213, the second actuation mechanism (not shown) simultaneously pushes the second connection The rod 215 moves the second clamp body 213 together with the first link 214 and the second link 215 toward the first clamp body 212.

Of course, the first actuating mechanism 216 and the second actuating mechanism can also bring the first link 214 and the second link 215 back to the original position from a position close to the first jig body 212.

The first clamp body 212 is screwed to the base 211 so that the first clamp body 212 can bear the pushing force when the second clamp body 213 clamps the roller set 3 without being placed and moved.

In summary, the assembly mechanism of the present invention and the assembly method thereof can more stably clamp the pulley block on the shaft body by the first clamp and the second clamp, so that the roller set can be more tightly fixed on the shaft body, so that The efficiency of the stable transfer panel can be achieved by the transmission mechanism of the transfer assembly.
