SOLDERING PART INSPECTION INSTRUMENT FOR MULTIPIN ELECTRONIC COMPONENT

摘要

PURPOSE:To inspect correctly the conforming and nonconforming soldering part by setting up a lighting device and photographing device at adequate position and by providing the decision means to analyze the pattern of the picture obtd. therefrom. CONSTITUTION:The table is made movable two-dimensionally in the axis x and axis y directions. The TV camera 3 for industrial use is installed on the upper part of the table as the photographing device and four pieces of the light 5 as the lighting device are set up so as to enable the lighting from both side faces of the multipin electronic component. Each light 5 is arranged to have a certain angle in the space with the substrate 1 so as to enable the lighting of the soldering part adequately. The camera 3 is connected with the control part 7 which makes a decision means and the light 5 is connected to the control part 7 via light switch 8. The control part 7 is composed by the microcomputer as well as the memory 7a storing the reference pictures, etc. of the soldering part and provides the terminal equipment with TV 9 for informing of the nonconforming soldering of the inspecting body.
