Embodiment
[0052] The present invention uses the robot to directly communicate with the laser, and controls the change of the power of the laser through the robot, so as to realize the purpose of the slow rise and fall of the laser. Since the present invention uses the robot to directly communicate with the laser, it involves fewer terminals, less communication time, faster speed and more convenient operation.
[0053] Such as figure 1 As shown, a control system for slowly rising and falling laser welding power, including a robot, an output module and a laser, wherein the output module includes a digital output module and an analog output module. The robot is connected with the digital output module and the analog output module through the corresponding bus. That is to say, the robot sends the laser on and off light signal to the laser through the digital output module, so as to control the laser on and off. The robot sends laser power control signals to the laser through the analog ou...

The invention discloses a laser device welding power slowly increasing and reducing control method. The laser device welding power slowly increasing and reducing control method comprises setting the period when a laser device starts emitting laser as a power slowly increasing time, and the period when the laser device stops emitting laser as a power slowly reducing time; when detecting that the laser device starts emitting laser, starting timing and detecting in real time a first timing time, and according to the first timing time and the power slowly increasing time, controlling to adjust thepower of the laser device to increase slowly; when detecting that the laser device stops emitting laser, starting timing and detecting in real time a second timing time, and according to the second timing time and the power slowing reducing time, controlling to adjust the power of the laser device to decrease slowly. The invention also discloses an electronic device, a computer readable storage medium and a laser device welding power slowly increasing and reducing control device and system. The laser device welding power slowly increasing and reducing control method, device and system has theadvantages of being high in response speed, convenient to operate and low in time consumption.
Description
technical field [0001] The invention relates to the field of laser welding, in particular to a control method, device and system for slowly increasing and decreasing laser welding power. Background technique [0002] At present, when the fiber laser is used for metal welding, the moment the laser emits light (turn on the light), because the laser power rises from zero instantaneously, the material from the starting point of the weld evaporates to form a small hole, resulting in the molten metal outside the hole wall under the action of thermal stress. Down and up pour out and accumulate at the starting point to form weld bumps. When the laser is turned off when the welding is completed, the power of the laser drops to zero instantly, the temperature of the molten pool drops suddenly, and the metal around the molten pool gradually solidifies, resulting in insufficient molten metal backfilling into the small hole, resulting in the surface at the end of the weld. Even severe p...
