ABSTRACT:
A tinning station for axial lead electronic components includes a presentation system for arranging a plurality of axial lead components in an elevated linear array with adjacent components lying parallel to each other. A pair of grippers, have a pair of parallel bars each having a longitudinal slot and a length at least as long as the length of the component array. These bars are moved toward or away from each other by an actuator which is mounted on a robotic arm. This arm is programmed to position the grippers adjacent to the array so that the actuator can cause the grippers to clamp the ends of the bodies of the components in the array. Then the arm dips the leads on each side of the array into the solder flux and subsequently into molten solder, thereby tinning the leads. The thickness of the grippers defines an untinned length of each component lead. A release fixture is used to dislodge any components which do not fall from the grippers when the grippers are separated.
