APPARATUS FOR INSPECTING ELECTRONIC COMPONENT INSERTION IN A PRINTED CIRCUIT BOARD AND THE METHOD THEREFOR

摘要

The present invention stores digital data of a scanner and includes a component information database for storing information as data of components to be inserted in the printed circuit board and a non-insertion inspection database for storing data of lead wire clinching directions inserted in each hole from predetermined numeric control data. A control section collects hole information as data from the digital data of the scanner, reads the clinching directions of the components inserted in each hole from the non-insertion inspection database, and judges insertion states of the components according to whether or not brightness exists by inspecting a brightness change in the clinching direction around a hole. The present invention inspects brightness while drawing concentric circles from the hole center, inspects whether there is a brightness change around a lead wire direction read from the non-insertion inspection database, and judges a good insertion and a bad insertion according to whether or not the brightness change exists.
