Component Positioning Device

Multiple components are simultaneously accurately positioned by oscillating a compartmented holder, with decreasing excursions about the ultimate location.

A table 1 is horizontally oscillatable along the two axes shown or others, as desired, by a cam mechanism within housing 2. The table has locating pins 3 over which are placed a master plate 4. The plate is provided with compartments 5 approximating the component size and into which components 6 have been individually placed. A ram 7, fitted with a vacuum chuck 8 for each compartment, is lowered over plate 4 to bring the vacuum chucks adjacent their respective components. Vacuum is applied through valve 9 to attract the components and restrain their movement. Table 1 is slowly oscillated in ever-decreasing excursions. During oscillation, the components are moved slightly by the compartment edges against the vacuum restraint. This results in accurately positioning each component on its chuck. Oscillations can be along orthogonal or acute axes or orbital, as required by the component configuration. Ram 7 is raised, lifting the positioned components by vacuum attraction. Plate 4 is removed and the element 10 to receive the components is substituted. Ram 7 is thereafter lowered to place the components on element 10 and the vacuum is terminated by valve 9, releasing the components.

The magnitude of the positioning excursions depends on the compartment and component dimensions and tolera...
