Electronic-component alignment method and apparatus therefor

An electronic-component alignment apparatus, comprising:

• a receiving table holding a first electronic component having two unobstructed alignment holes perforated at predetermined positions thereof so as to be spaced away from each other by a predetermined interval;
• a position-adjusting mechanism holding a second electronic component which is disposed so as to face the receiving table and which has two alignment marks formed at predetermined positions thereon so as to have an interval therebetween in agreement with that between the two aligning holes;
• a mark-recognition apparatus which is disposed rearward of the receiving table and which, in a state in which the alignment marks of the second electronic component are visually unobstructed within the alignment holes of the first electronic component, captures the alignment marks and the corresponding alignment holes in the same fields of view thereof and measures the positions of the two components,
• wherein, by using images whose positions are measured by the mark-recognition apparatus, the two components are aligned with each other by adjusting the position of the second electronic component with the position-adjusting mechanism such that the alignment marks of the second electronic component lie at predetermined positions in the two alignment holes of the first electronic component,
• wherein the position-adjusting mechanism moves and rotates the second electronic component in the X and Y directions and in the θ direction, respectively, on a horizontal plane, and
• wherein the entire position-adjusting mechanism is movable in the Z direction on a vertical plane and bonds the first and second electronic components to each other.
