The invention discloses a drilling device with a
drill capable of automatically detecting and tracking the center of a suture needle end. The drilling device comprises a
programmable logic controller (PLC), a drilling mechanism, a computer, a
charge coupled device (CCD) sensor, cameras and a clamp. The clamp clamps a suture needle to be drilled, the cameras are positioned and installed on the X-axis and the Y-axis of the suture needle to be used for shooting the needle end of the clamped suture needle and the
drill; the cameras transmit shot pictures to the computer through the CCD sensor, and a picture
processing program module is installed in the computer and used for
processing picture information sent by the cameras, the position of the needle
tail circle center and the position of the
drill are determined by
algorithm analysis, and by communication with the PLC, an instruction for adjusting the drilling mechanism is sent out. According to the drilling device, by applying a
machine vision technology, the automatic detection and tracking of the circle center are performed through picture
processing by the computer, the
punching center problem is solved, and the drilling device is high in
automation degree and good in
punching quality, reduces defective rate and is low in cost, high in efficiency and quick in speed.
