ABSTRACT:
In an automatic delivery system for the mounting of electronic components on a circuit board, the components are sequentially delivered to a movable carriage assembly for proper positioning for engagement by a component pick-up device for insertion on the circuit board. Positioned adjacent to the outlet of a delivery tube internally contoured in accordance with the component configuration is a pivoting retaining member which engages the component after it exits the delivery tube and is deposited upon the pneumatically actuated, linearly displaced carriage assembly to ensure proper orientation of the component thereon as it is displaced toward the component pick-up device. The carriage is contoured in a complementary manner relative to the component in providing a "cradle effect" for maintaining proper component orientation and position with respect to the pick-up device. During the linear displacement of a first component into proper position for engagement by the pick-up device, a second component in the delivery tube is engaged and displaced downward along the tube by means of a component release mechanism so as to exit therefrom and be deposited upon the carriage assembly after it is retracted to an initial, unloaded position. The cycle is then sequentially repeated for each electronic component. The carriage assembly is provided with a telescoping plunger pin or shaft which engages the component and maintains it stably positioned on the carriage assembly during the linear displacement thereof.
