[0017] In this implementation scheme, the X-axis motion control 3 and the Y-axis motion control 5 are set to perform motion control in the X and Y directions, so that the CCD vision component 8 can take pictures of the carrier block 7, thereby calculating the center position of the CCD vision component 8. At the same time, when continuing the motion control and moving, the left flying needle 9 or the right flying needle 10 is made to contact the carrier block 7. At this time, the carrier block 7 is connected to the left flying needle 9 or the right flying needle 10, and a voltage is output to the motion control card to generate a signal, thereby sending out a signal to stop the motion control, and calculating the moving distance at this time, comparing the deviation with the center position of the CCD vision component 8, so as to accurately calculate the positions of the left flying needle 9 and the right flying needle 10.
