The invention discloses a compensation method for a mobile laser galvanometer welding system, which is applied to the mobile laser galvanometer welding system. The compensation method includes presetting the optimal path of a manipulator according to a product to be welded; giving the galvanometer speed and calculating the manipulator speed Critical value; calculate the displacement compensation amount of the manipulator according to the principle of circular interpolation; convert the displacement compensation amount to obtain the compensated point of the manipulator and input it to the controller so as to compensate the moving laser galvanometer welding system. The method of the present invention artificially sets the optimal path for manipulator welding, and compensates the welding process of the moving laser galvanometer according to the principle of circular interpolation, and compensates the displacement of the manipulator in the process of moving at a constant speed within a fixed time so that it does not need to stay at the The position of the workpiece to be welded is processed, so as to minimize the waste of non-productive time caused by repeated positioning before each section of welding.
Description
technical field [0001] The invention relates to the technical field of laser precision machining equipment, in particular to a compensation method for a moving laser vibrating mirror welding system. Background technique [0002] In the field of laser welding, galvanometer laser welding has become more common in the field of precision welding. The galvanometer lens inside the galvanometer relies on the principle of lens deflection to guide the laser beam to run to a wider plane position. The appearance of the galvanometer makes laser precision welding The processing area is more flexible and the deflection speed is faster, which makes the processing speed a qualitative leap. However, in the actual production process, due to the large processing volume and long production cycle, pure galvanometer welding can no longer meet the processing requirements. Efficiency requirements, under the production pressure of the production line, it is necessary to reconstruct a more efficient ...
