At this time, the first driving cylinder 311 drives the first material picking column 334 to realize the function of horizontally moving the torsion spring 02. Finally, the second driving cylinder 322 drives the rotating block 324 to rotate, thereby driving the torsion spring 02 on the first material picking column 334 to rotate, so that the torsion spring 02, which was originally at a certain inclination angle with the horizontal plane, is adjusted to a position parallel to the horizontal plane, so as to facilitate the subsequent second automatic material picking mechanism 5 to perform secondary material picking operation on the torsion spring 02.

At this time, the fourth driving cylinder 41 drives the torsion spring 02 on the second material picking column 53 to move horizontally, and the fifth driving cylinder 44 drives the second material picking column 53 to descend again, and moves the torsion spring 02 on the second material picking column 53 to just above the second positioning column 67. At this time, the sixth driving cylinder 52 drives the first material return column 54 to descend, and the first material return column 54 fits the center of the torsion spring 02 on the second material picking column 53 on the second positioning column 67. At this time, the motor 63 drives the shifting block 65 to rotate, and the shifting block 65 drives the torsion spring 02 to rotate, adjusts the posture of the torsion spring 02, and facilitates the subsequent automatic material picking assembly mechanism 7 to pick up the material of the torsion spring 02 and assemble it to the shell 01.

[0042] When the torsion spring posture automatic adjustment mechanism 6 adjusts the posture of the torsion spring 02, the fourth driving cylinder 41 drives the first clamp 75 and the second clamp 76 to move to the top of the torsion spring posture automatic adjustment mechanism 6. At this time, the fifth driving cylinder 44 drives the first clamp 75 and the second clamp 76 to descend and clamp the torsion spring 02 on the second positioning column 67. At the same time, the second material picking column 53 on the second automatic material picking mechanism 5 descends synchronously to pick up the torsion spring 02 on the first material picking column 334. After the first clamp 75 and the second clamp 76 have finished clamping the torsion spring 02, the The fifth driving cylinder 44 drives the first clamp 75 and the second clamp 76 to rise, the fourth driving cylinder 41 drives the first clamp 75 and the second clamp 76 to move horizontally, and the fifth driving cylinder 44 drives the first clamp 75 and the second clamp 76 to descend again, so that the torsion spring 02 located between the first clamp 75 and the second clamp 76 moves to a position directly above the desired installation position inside the belt shell 01. At this time, the seventh driving cylinder 72 drives the second material ejection column 74 to descend, and the second material ejection column 74 presses the torsion spring 02 located between the first clamp 75 and the second clamp 76 to the desired installation position inside the shell 01.
