Abstract
The invention is directed to a method and apparatus for gripping DIP components automatically without the need for shutting down the machine to change the tooling assembly when handling components which differ in width. Two sets of fingers are provided, with one set inside the other, such that engagement of the inner pair with a wide component causes automatic retraction of them sufficiently for gripping of the component by the outer pair. In the absence of a component, the inner pair of fingers is automatically extended for subsequent component handling.
Claims12
A method of handling components having bodies which may differ in at least one particular dimension, from component to component, and comprising the steps of:
- providing a gripper assembly having at least two pairs of fingers with a spacing between fingers of each pair of fingers providing a gripping range different from at least one other pair of fingers in order to grip components having said particular dimension corresponding to said gripping range of said each pair of fingers;
- selecting automatically between said pairs according to said particular dimension of each component;
- and
- gripping each said component upon actuation of said assembly.
A method of handling components having bodies which may differ in at least one particular dimension, from component to component, and comprising the steps of:
- providing a gripper assembly having at least two pairs of fingers with each pair of fingers having a gripping range different from at least one other pair of fingers and being adapted to grip components having said particular dimension corresponding to said gripping range of said each pair of fingers;
- selecting automatically between said pairs according to said particular dimension of each component;
- positioning one of said pairs of fingers at an extended, component handling location relative to a support bracket, with remaining pairs of said fingers retracted a way from said component handling location;
- retracting said one pair of fingers and extending another pair of said fingers, automatically and according to said particular dimension, in order to accomplish gripping of each component;
- and
- gripping each said component upon actuation of said assembly.
A method of handling components having bodies which may differ in at least one particular dimension, from component to component, and comprising the steps of:
- providing a gripper assembly having at least two pairs of fingers with a spacing between fingers of each pair of fingers providing a gripping range different from at least one other pair of fingers in order to grip components having said particular dimension corresponding to said gripping range of said each pair of fingers;
- engaging each component with at least one of said pairs of fingers in order to select automatically between said pairs according to said particular dimension of each component;
- and
- gripping each said component upon actuation of said assembly.
A gripper assembly for gripping components having bodies which may differ in at least one particular dimension from component to component, and comprising:
- plural pairs of component gripping fingers, with a spacing between said fingers differing from pair to pair in order to handle components within a certain size range of said particular dimension;
- and
- means, operatively associated with said plural pairs of fingers, for selecting automatically between pairs of component gripping fingers according to said particular dimension of each component and gripping said component upon actuation of said assembly.
An apparatus for handling components having bodies which may differ in at least one particular dimension, from component to component, and comprising:
- a gripper assembly having at least two pairs of fingers with fingers of each pair of fingers having a gripping range different from at least one other pair of fingers and being adapted to grip components having said particular dimension corresponding to said gripping range of said each pair of fingers;
- and
- means, operatively associated with said gripper assembly, for selecting automatically between said pairs according to said particular dimension of each component;
- means, operatively associated with said gripper assembly, for gripping each said component upon actuation of said assembly;
- means, operatively associated with said gripper assembly, for positioning one of said pairs of fingers at an extended, component handling location relative to a support bracket and remaining pairs of said fingers retracted away from said component handling location;
- and
- means, operatively associated with said gripper assembly, for retracting said one pair of fingers and extending another pair of said fingers, automatically and according to said particular dimension, in order to accomplish said gripping.
An apparatus for handling components having bodies which may differ in at least one particular dimension, from component to component, and comprising:
- a gripper assembly having at least two pairs of fingers with each pair of fingers having a gripping range different from at least one other pair of fingers and being adapted to grip components having said particular dimension corresponding to said gripping range of said each pair of fingers;
- and
- means operatively associated with said gripper assembly, for engaging each component with at least one of said pairs of fingers in order to select automatically between said pairs according to said particular dimension of each component;
- and
- means, operatively associated with said gripper assembly, for gripping each said component upon actuation of said assembly.
