Abstract
For aligning an electronic component to a required orientation, the electronic component is picked up and it is inspected while it is being held to determine its initial orientation. A précising mechanism is then rotated to correspond to the initial orientation of the electronic component. After the electronic component is secured on the précising mechanism in the initial orientation, the précising mechanism is rotated to align the electronic component to the required orientation. Thereafter, the electronic component that has been aligned to the required orientation may be picked up for further testing and/or processing.
Claims11
A method for aligning an electronic component to a required orientation, comprising the steps of:
- picking up the electronic component;
- inspecting the electronic component to determine its initial orientation;
- rotating a précising mechanism to correspond to the initial orientation of the electronic component;
- securing the electronic component on the précising mechanism in the initial orientation;
- rotating the précising mechanism to align the electronic component to the required orientation;
- and thereafter
- picking up the electronic component that has been aligned to the required orientation.
An apparatus for aligning an electronic component to a required orientation, the apparatus comprising:
- a plurality of pick-heads for picking up electronic components;
- an inspection station that is operative to inspect an initial orientation of an electronic component while it is held on a pick-head;
- and
- a précising mechanism that is in operative communication with the inspection station such that the précising mechanism is rotatable to correspond to the initial orientation of the electronic component which has been determined;
- wherein the précising mechanism is further configured to receive the electronic component in its initial orientation and to rotate the electronic component to the required orientation.
