1. Robot fiber laser cutting machine and welding system

The system is mainly composed of 500w fiber laser, six-axis robot, multi-function processing head, three-dimensional flexible welding tooling, CCD positioning system, airflow system, computer off-line programming system and servo system.

The system takes the robot as the main control unit, on the one hand, it controls the movement of the robot to perform the processing; On the other hand, it controls the laser output, repeats the bin product, duty cycle, gas on-off and motion trajectory. The experimental results of cutting 2mm thick 304 stainless steel plate by using this system show that when the cutting speed is 15 mm/s and the output power of the laser is 400w, the cutting effect is good, the incision width is small, the cutting surface is relatively smooth, and the slag is less.

The results of laser welding experiments on a 1.5mm thick 304 stainless steel plate show that when the laser output power is 450w, the welding speed is 7 mm/s, and the positive defocusing amount is 2mm, the welding effect zui is good, the front and back of the weld is good, the defects such as porosity, undercut and collapse are few, and the weld forming zui is ideal.

2. 3D laser processing robot cutting machine

The cutting system can be used for three-dimensional laser cutting, mainly including fiber laser, fiber light guide system, laser cutting head, fixture, water cooling system and industrial robot system. The fiber laser output laser power can reach 4000w, the robot is six-axis, and the repeated positioning accuracy is high, up to 0.07mm. Using off-line automatic programming, combined with the data model to find out the boundary contour of the three-dimensional workpiece and the normal line on the contour line on the 3D software platform, and then control the robot to do the contour trajectory movement along the normal direction.

The energy distribution of laser processing, laser power, metal liquid-solid state transition, laser cutting head moving speed, auxiliary gas pressure, etc. have a significant impact on cutting quality, through theoretical analysis, numerical simulation and experimental combination, to find reasonable process parameters, and stored in the system. The system uses three-dimensional trimming, hole cutting and separation of body-in-white stamping parts, replacing traditional mold processing.
