A INSPECTING DEVICE OF SOLDERING AND METHOD TO BE COMPATIBLE

摘要

PURPOSE: An apparatus for examining a solder and a proper method thereof are provided to improve an exact detection of whether a solder examining apparatus is defective or not. CONSTITUTION: The first illumination lamp(1) emits a solder fillet(F) on the same axis with a camera(53). The second illumination lamp(2) is installed to have a different radiation angle from that of the first illumination lamp(1) and obtains an image which is inversed from an image obtained by the first illumination lamp(1). A vision apparatus(3) synthesizes the image signals of the first illumination lamp(1) and the second illumination lamp(2) and outputs the formed condition of the solder fillet(F) to a monitor(55) as well as judging whether the solder fillet condition is good or not. In a state that the first illumination lamp(1) is turned on and the second illumination lamp(2) is turned off, the first image is obtained. In a state that the first illumination lamp(1) is turned off and the second illumination lamp(2) is turned on, the second image is obtained.
