During the clockwise rotation of the connecting member 420, the motor 322 continues to rotate while the fifth protrusion 424e is electrically connected to the fourth connecting head 438. As the clockwise rotation of the connector 420 continues, the piston rod of the clamp cylinder 234 is retracted to release the product 20 when the fourth protrusion 424d is electrically connected to the third connector 436. When the third protrusion 424c is electrically connected to the second connector 434, the piston rod of the feeding cylinder 228 retracts to drive the feeding tray 226 to rotate counterclockwise, so as to deliver the product 20 to the discharging tray 224.

The connecting member 420 continues to rotate clockwise, and finally the first protrusion 424a is electrically connected with the first connecting head 432, the piston rod of the driving cylinder 315 is controlled to extend out again, the main shaft 330 moves towards the direction close to the product 20, and the automatic drilling equipment circulates the actions, so that the flow process is realized.

Above-mentioned automatic drilling equipment can realize automatic feeding and automatic drilling, easy operation, and work efficiency is high, can reduce the cost of labor.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
