The sorting plate can adjust the position and direction and is suitable for the arrangement of micro-drills of different models. By setting a return tray, the micro-drills that fall into the return tray can automatically return to the micro-drill loading frame under the action of the vibration motor, and there is no need to manually recover the micro-drills that fall during the conveying process. The cooperation of the micro-drill loading frame and the feed conveying channel realizes the automatic loading of the micro-drills one by one, which is convenient for the subsequent sorting and adjusting mechanism to sort and adjust one by one. The cooperation of the pushing cylinder and the pushing plate in the aggregate trough can prevent the micro-drills from accumulating at the feeding end of the aggregate frame.
