[0040] Furthermore, the unloading mechanism 600 includes a unloading ramp 601 extending left and right, the unloading ramp 601 is higher at the left end and lower at the right end, and a process hole 602 close to the left end is opened on the unloading ramp 601, and an air gripper 603 with claw heads symmetrically arranged on the left and right and claw mouths facing upwards is arranged in the process hole 602, and the air gripper 603 is provided with a sixth cylinder 604 for controlling its vertical up and down movement.

[0041] In this embodiment, first, the precision tubes to be processed are stored on the loading downslope plate 203 of the loading mechanism 200. Guided by the slope, the precision tubes are concentrated at the right end of the loading downslope plate 203 and lean against the first baffle plate 205. The fourth cylinder 209 controls the bottom loading top block 208 to move upward, and lifts the precision tubes thereon until they roll down to the loading upslope plate 204 until they are blocked by the second baffle plate 206. The fifth cylinder then controls the side loading top block 211 to move forward, and the precision tubes to be processed are ejected from the side loading hole 210, and are grasped by the clamping mechanism 701 on the moved-in-place transfer assembly 700.

[0042] First, the precision tube to be processed is grabbed by the clamping mechanism 701 and brought to the hole punching mechanism 300. The precision tube is positioned on the first positioning column 304, and the hole punching head 305 completes the punching of the side hole 801.

[0045] Finally, the clamping mechanism 701 grabs the processed precision tube to the unloading mechanism 600 to realize automatic unloading.

[0046] Among them, the unloading principle of the unloading mechanism 600 is as follows: the clamping mechanism 701 transfers the processed precision tube to the air gripper 603, the air gripper 603 clamps the precision tube and carries the precision tube to a state above the process hole 602; the clamping mechanism 701 is reset, the air gripper 603 first releases the precision tube, and then is controlled to move downward by the sixth cylinder 604 until the air gripper 603 is located below the process hole 602. Since the process hole 602 blocks the precision tube from moving downward, it is left on the unloading ramp 601 and rolls down with the slope.
