It should be pointed out that in view of the fact that the welding torch tracks the welding groove in real time in order to ensure the correctness of the welding, the automatic tracking of the weld seam is the prerequisite and basis for the realization of the entire welding process. Therefore, from a general point of view, the two-dimensional The real-time tracking process uses local closed-loop control to achieve the real-time control requirements for automatic welding seam tracking. The direction of equipment design and maintenance correction. This amount is processed by the CPU and then the slider mechanism driven by the stepper motor is driven by the interface circuit and drive circuit to drive the CCD until the center line and the parallel line of the welding groove are aligned and the deviation is zero. So far, the welding gun moves with the CCD, thus indirectly realizing the welding seam tracking process. In view of the fact that the control system uses two different types of motors: AC servo motors and stepper motors, for the above two different motors and their drivers, according to the drive control method of the driver and the resources and interface of the DSP application board, respectively Different control methods adjust the motor speed and direction. In addition, based on the convenience of operation and control, a wired remote control is designed to allow users to control input parameters and operation processes through knobs, gear switches, buttons, etc. on the remote control; meanwhile, there are Speed ​​LED display, power supply, whether the welding gun is centered, welding groove parallel line LED display, etc., have good interactivity. At present, domestic valve electric devices generally adopt common mechanical transmission structure forms such as worm drive or ordinary gear drive structure.
