Title: Electronic component mounting apparatus
Inventor: OZAWA MASATO
IPC: H05K13/04
Filed: 1994-09-16
Abstract: PURPOSE: To position a component by processing the picture signal of the component by a complex type filter, and detecting the representative position of the predetermined site of the component. CONSTITUTION: An IC 5 sucked and picked up by an IC supply unit 4 is carried to the suction port of a TLC unit 7 by an X-Y robot 3, and imaged by a TLC camera. The imaged picture signal of the IC 5 is sampled and quantized to be converted into a digital density signal. Further, windows are set to upper, lower, left and right pin rows, and the picture signals of the upper, lower, left and right pin rows are extracted. A complex type filter corresponding to a predetermined spatial frequency is applied within the window, and a zero-cross point of the phase is obtained to extract a site representing the position of the pin (the central position of the pin in this case). Thus, since the predetermined site of the component is detected as the representative position based on the output of the complex type filter, the component can be positioned rapidly and accurately.
