ABSTRACT:
A pick and place device for populating a circuit board is operated manually. One or more pickup heads in a carriage is lowered to engage a component by vacuum, raised for carrying the component to a desired position over the circuit board and lowered to set the component. The component can be rotated, and the vacuum is operated automatically during pick and place movements, accomplished with one hand via a rotatable handle arrangement. A hand rest places the user's fingers in range of the handle and assists in coarse positioning of the carriage. The handle and hand rest are mountable on opposite lateral sides of the carriage head assembly. Finger controlled fine positioning guides also support the carriage for movement relative to the coarse guide. Coarse guidance is by a telescoping arm and lateral rail or the like. Fine guidance is by a short span two-axis slide block coupling the carriage to the telescoping arm. The handle lifts or lowers a control plate and is coupled to convey rotation. A number of pickup heads can be carried in a turret that indexes to bring them into position where a contact member conveys rotation and moves the pickup head axially. Each pickup head has an individual control for coupling to the vacuum, including a push-on, push-off switch operated with movement of the control plate.
