APPARATUS FOR DISPLAYING LASER WELDING REGION

摘要

PURPOSE: A device for indicating a laser welding point is provided to capture the laser welding point using a camera and indicate the laser welding point as a cross line so as to easily confirm the laser welding point. CONSTITUTION: A device for indicating a laser welding point includes an analog-to-digital converter(22), a video signal processor(24), a key input unit(26), a cross line generator(28), an image superposition unit(30), and a display unit(32). The analog-to-digital converter converts a video signal of a laser welding point, provided by a camera, into digital video signal. The video signal processor processes the digital video signal into an image signal to be displayed on a screen. The key input unit is used to input a key for moving vertical and horizontal lines forming a cross line in vertical and horizontal directions. The cross line generator generates a video signal for indicating the cross line. The image superposition unit superposes the video signal for indicating the cross line on the video signal to be displayed on the screen.
