New universal laser scanning head detector

In order to overcome the disadvantages of the traditional head detection, such as limited size of measuring models, low accuracy of artificial reading and resource cost of plate making, a non-contact laser detection device, suitable for shape deviation detection of the head in different sizes, was designed with laser scanning 2-D contour continuously. Work principle, scan mode, system components and specific design of each subsystem of the laser scanning head device were introduced. A head with inner diameter of 800mm was verified in experiment. The results show that the laser scanning head device can make the detection automatically with high-precision, high-efficiency. The ideal accuracy can reach 1mm~2mm.
