Abstract
A method and apparatus for bending probe pins that is semi-automated and uses machine vision to eliminate human error.
Claims20
An apparatus for bending a probe pin comprising:
- a base structure having a guide block attached to the top of said base structure;
- a fixture also attached to the top of said base structure having a lower vision camera;
- said fixture further comprising a bending fixture being movable between two positions in order to facilitate the bending of a probe pin;
- such that a probe pin can be placed on the guide block and pushed into place, then measured by the vision camera to check on positioning and subsequently bent by the bending fixture.
