In the embodiment, each contact point is obtained by high-voltage contact sensing detection, the computer system increases the voltage of the welding wire and performs an action to enable the welding wire to approach the base metal slowly, and when the welding wire touches the base metal, the welding wire is conductive with the base metal (or the welding wire is discharged at the tip, and the thin oxide film on the surface of the workpiece can be punctured by the high voltage), so that the sensor detects the workpiece and memorizes the coordinate data at the moment.
As shown in fig. 2, the function of detecting the spatial coordinate data of the workpiece by using the high-voltage contact sensing can be implemented by, for example, finding a suitable position to locate the sensing start point (X, Y, Z), setting the welding start point (X1, Y1, Z1) on the workpiece by correcting the sensing contact point (X ', Y ', Z ') on the workpiece, and automatically calculating the correction distance D (which can be understood as a vector including the direction and the length) from the sensing contact point to the welding start point by the system program when the computer is subjected to teaching programming (the robot is manually operated by the teaching controller to complete the desired motion track and the operation command is recorded as a program, and the program can automatically run and reproduce the desired motion track).
When the position of the workpiece changes, the robot can detect the current position of the workpiece through the sensing action (the welding wire with the heightened voltage linearly moves from the teaching preset sensing initial point along the teaching preset direction until the welding wire touches the workpiece and records the contact point coordinate at the moment of touch discharge) set during the teaching programming, and performs correction calculation according to the correction distance D calculated during the teaching programming, so as to obtain the correct welding initial point of the welding gun 3 after the position of the workpiece changes.
It can be understood that the welding start point is shifted according to the shift of the workpiece, and although the spatial position of the welding start point is changed, the absolute position of the welding start point on the workpiece is not changed, and the robot is repositioned to the welding start point on the workpiece through the sensing detection and the correction calculation of the robot.
In practical application, if the workpiece has position deviation in multiple spatial directions, multiple sensing detection can be set for superposition correction, that is, the starting point of the next sensing action is obtained by correcting the contact point of the previous sensing action, and so on, the contact point of the last sensing action is corrected to obtain the final welding starting point (or welding ending point).
