Automated apparatus and method for positioning multicontact component
First Claim
1. A method of positioning a multi-contact component on a circuit board, comprising:
- picking up a component by a movable positioning member;
moving said component over a first viewing means for orientation determination of the component;
determining component lead alignment by moving the positioning member to scan the entire component across the first viewing means;
moving said positioning member to position a second viewing means mounted on said movable member to view a target on said circuit board for orientation determination of the target;
moving said positioning member to position said component over said board, said component being positioned and oriented relative to said target from said orientation determination by said first and second viewing means; and
placing said component on said board.

Abstract
Automated positioning apparatus for positioning multi-contact components on a circuit board utilizes automated members having a high degree of repetitive movement but not in themselves accurate, such member being relatively inexpensive. A positioning member picks up a component and moves it over a first viewing head. The component is viewed and its orientation determined. A viewing head on the positioning member is then positioned over a target on a circuit board and its position and orientation determined. The results enable the positioning member to position the component on the circuit board in the correct position and orientation. The viewing heads are calibrated for aspect ratio and pixel dimension. Also, the field of view of the viewing heads are calibrated for orientation relative to the positioning member. The position and orientation of the viewing head on the positioning member relative to a pick-up member on the positioning member is also obtained.
