Abstract

The subject method and device are to be used in robotic applications for assembly and component insertions, and allow the position of component leads, before insertion by the robot, to be known with accuracy and the bent pins to be detected. The X, Y and 0 positions of the component pins before the insertion of the component by the robot are detected with a maximum accuracy. The computer controlling the robot receives the X, Y positions and the 0 indication or the indication of a bent pin and then performs the insertion according to the received data and indications. As shown in Fig.

Component Position Recognition Method and Device for an Assembly Robot

The subject method and device are to be used in robotic applications for assembly and component insertions, and allow the position of component leads, before insertion by the robot, to be known with accuracy and the bent pins to be detected. The X, Y and 0 positions of the component pins before the insertion of the component by the robot are detected with a maximum accuracy. The computer controlling the robot receives the X, Y positions and the 0 indication or the indication of a bent pin and then performs the insertion according to the received data and indications. As shown in Fig. 1, the system comprises a visual detector made of two photodiode arrays looking at the pin of the component, a microprocessor working as a controller for the visual detector and communicating with the robot controller through data in and data out (DI/DO) lines, and the robot and its controller which uses the received data to correct the X, Y positions, to rotate the component to find the correct alignment and analyze the position again or to move the component to a pin straightener if the pins are bent. This visual sensing system allows an automatic insertion of the components. The component feeders function is limited to the supply of the components one by one without having to adjust their positions. After the gripping sequence of the component by the robot, the position of the component is recognized by the pho...
