Similarly, several front sliders C are placed into the first vibrating plate 31 of the front slider assembly mechanism 4. Further, the oiling device 22 in the bracket assembly mechanism 2 applies lubricating oil to the mounting groove on the bracket A. Then, the bracket assembly robot 23 picks up the bracket A and installs it into the fixture 11 on the rotary transfer mechanism 1, completing the loading of the bracket A. As the rotary transfer mechanism 1 rotates continuously, the fixture 11 sequentially switches to different workstations. When the number of fixtures 11 equals the number of workstations, it can be ensured that each fixture is properly positioned after each transfer.

Then, the pre-positioning device 54 tilts the damping tube 54 and clamps and pulls out the plug of the damping tube 54, completing the pre-positioning of the damping tube D to facilitate the fastening of the damping tube D. Then, the fourth gripper device 56 of the damping tube assembly robot 53 grips the damping tube D from the pre-positioning device 54 and fastens it onto the bracket A. At this time, because the body of the damping tube D is tilted, it first contacts the bracket A. After the tail of the damping tube D is fastened onto the bracket A, the fourth pusher cylinder 563 fastens the plug of the damping tube D onto the bracket A. On the front slider C, the damping tube D is fastened, so that when the rear slider B and the front slider C slide, the damping tube D can play a buffering role. Further, the second material distribution device 62 of the spring assembly mechanism 6 separates the springs E one by one in a staggered manner, and the fifth gripper device 65 and the sixth gripper device 66 clamp the two ends of the springs E. Then, the spring assembly robot 64 fastens the two ends of the springs E to the bracket A and the rear slider B respectively, thus completing the assembly of the springs E. Further, when the rotation and transfer mechanism 1 moves the assembled damper assembly to the finished product discharge mechanism 7, the finished product discharge mechanism 7 removes the damper assembly from the fixture 11. Then, the unloaded fixture 11 continues to be transferred to the bracket assembly mechanism 2 for the next round of assembly process.
