    摘要: A vacuum spindle for picking and placing components is operatively associated with a turret assembly which carries a supply of various component engaging tips for the spindle in corresponding holes or chambers of the turret. During picking and placing of the components, the spindle extends through the turret chamber from which the tip of the spindle was acquired. In order to exchange tips, the spindle is retracted to a first position at which the tip may be relocked in its chamber of the turret and then to a second position which is sufficient for the turret to be rotated for coaxial alignment of the spindle with another chamber and tip. Then, the replacement tip is acquired by extending the spindle into engagement with the tip and unlocking it from its chamber of the turret. Thus, various tips for the spindle may be interchanged after placement of a component and while the spindle is being repositioned in X and Y to the next pick-up site without the need to stop at an intermediate location.

    摘要: An adapter is attached to the end of a vacuum spindle in order to facilitate automated fastening and unfastening therewith of various vacuum nozzles. During fastening of a nozzle, vacuum is utilized to pull and hold the adapter and nozzle together with a force which is much greater than the mechanical detenting which is conventional in this art. The various nozzles may have component engaging tips of different sizes and configuration such that each nozzle is selectable as appropriate to the size and contour of the component to be held by vacuum drawn through the spindle. A novel reservoir housing a multiplicity of replaceable vacuum nozzles is also disclosed whereby the nozzles may be exchanged without any external separation or attachment force supplied by the downward or upward movement of the spindle.

    摘要: The present invention features a method and apparatus wherein a component in a component placement machine is rejected during the placement cycle and subsequently retained in a component rejection station. A component is imaged and the image processed using an automated vision system. The image processing determines whether the component is placeable based upon a comparison of the component image to preprogrammed mechanical parameters for the component. A non-placeable component is rejected into a reject station with means to retain the component. Because a component can not escape the reject station, there is no degradation of the placement machine performance.
