After finding limit portion, Z axle servo motor drive Z axle screw rod slip table module's slip table begins the up-and-down motion laser and seeks metal and coils nine o' clock directions of convex surface. After finding nine o' clock directions, the slip table of Y axle main shaft lead screw slip table module is moved forward to Y axle main shaft servo motor drive, and according to the mark distance of the best mark of laser etching machine is beaten in the focus of laser, to mark the completion back, the laser etching machine begins to beat mark the mark, and laser mark does not need chinese ink mark by laser etching promptly and environmental protection and energy-conservation.
Specifically, the device is used in cooperation with Siemens S1200PLC, and Siemens S1200PLC is provided with a touch screen. When the device is needed to carry out laser etching marking, the device is powered on, the zero position of the marking mechanism device is calibrated, the device is configured into an automatic mode, and after the metal coil produced by the production line is rolled out, the metal coil is conveyed to a laser marking position by the conveying trolley. The device obtains a metal coil in-place signal through S1200PLC, the device starts to act according to logic, the X-axis servo motor drives the sliding table of the X-axis screw rod sliding table module to move rightwards, and meanwhile the Z-axis driving mechanism, the laser etching machine gun head, the loosening laser sensor and the sick laser sensor can move rightwards along with the X-axis in parallel.
After the SICK laser sensor obtains the edge information of the metal coil, the X axis continues to operate, when the laser etching gun head moves to the optimal etching position away from the edge, the X axis stops, the Z axis servo motor drives the sliding table of the Z axis screw rod sliding table module to operate up and down, and the laser etching machine gun head, the loosening laser sensor and the SICK laser sensor can operate up and down synchronously. The laser sensor is compared and calculated when moving up and down, and the calculation result can change synchronously along with the movement of the Z axis. When the calculation result finds the side salient point (nine o' clock direction) of the metal coil, the Z-axis servo motor drives the sliding table of the Z-axis screw rod sliding table module to stop, and the band-type brake coil of the Z-axis servo motor acts to prevent the gun head of the laser etching machine from running downwards due to inertia.
When the salient points (nine o' clock direction) on the side surface of the metal coil are determined, the Y-axis servo motor drives the sliding table of the Y-axis spindle screw rod sliding table module to move forwards, and meanwhile, the X-axis screw rod sliding table module, the Z-axis screw rod sliding table module, the laser etching machine gun head, the loosening laser sensor and the mock laser sensor synchronously move forwards. And when the sick laser sensor moves forwards along with the sliding table of the Y-axis spindle screw rod sliding table module, the distance is fed back in real time.
