This article describes a robot vacuum gripper and insertion monitor device which senses bent pins or improper alignment of components dynamically. Throughout the electronics module insertion industry, there is a need for methods for detecting bent pins, dynamically, i.e., during insertion of components into printed circuit boards. The device disclosed herein utilizes a sensor which detects upward movement of a component if incorrect alignment or a bent pin inhibits insertion. Fig. 1 is a side view of the present device. A vacuum gripper 1 is mounted on robot shaft 2. The gripper insertion mechanism is shown in detail in Fig. 2. A conductive sponge 3 and a movable pad 4 are mounted in a cavity at the end of gripper 1. A plate 5 is positioned between the conductive sponge and movable pad.
