Abstract
Abstract An improved apparatus for body-to-lead measurements for components includes multiple light beams formed by LED-photodiode pairs or multiple light detectors with a multidirectional light source. The apparatus is self-contained and requires no position information of the gripper carrying the component.

Total Claims: 2
Claim 1
Independent Claim
149 words
Apparatus for sensing a position of a lead of a component comprising first means for producing a first light beam being adapted to traverse a first path and to be interrupted by the lead, first means for sensing the first light beam, second means for producing a second light beam being adapted to traverse a second path at an angle to said first path and to be interrupted by the lead and second means for sensing the second light beam, characterized in that the apparatus comprises third means for producing a third light beam being adapted to traverse a third path at an angle to said first and said second path and to be interrupted by the lead, third means for sensing the third light beam and means for calculating the avarage position of the lead based on the respective point of times of interruption of the light beams.
Claim 2
Dependent Claim
116 words
Apparatus as claimed in claim 1, characterized in that, the apparatus comprises a gripper for carrying the component, fourth means for producing a fourth light beam being adapted to traverse a fourth path and to be interrupted by the gripper, fourth means for sensing the fourth light beam, fifth means for producing a fifth light beam being adapted to traverse a fifth path and and to be interrupted by the gripper, fifth means for sensing the fifth light beam and means for calculating the position of the gripper based on the respective point of times of interruption of the fourth and fifth light beams and calculating the position of the lead with respect to the gripper.
