Automated fitting and soldering of components on three=dimensional SMT circuit boards

摘要

Circuit boards (7) are extracted from a supply magazine (15) by an industrial robot (13) holding the board in grippers (14). The robot arm is moved through an arc and passes beneath a solder paste dispenser (2) that is pneumatically powered and is coupled to a controller (12). Components (4) to be mounted on the board are extracted from a feed unit (9) with a linear slide mechanism (11). A CCD camera (5) monitors the position of the component being handled relative tot he board and a correction is applied to the robot to ensure correct alignment for insertion onto the board. The components are soldered into place by passing under a laser soldering tool (6, 7).
