Bar code and data-matrix code markings

Marking of the cylinder crankcase at different positions requires to move the laser scanner unit in the XY-plane by 400 x 700 mm and in Z-direction by a 100 mm. The laser components are mounted in the bottom part of the machine body. The laser beam is directed vertically upward on to the workpiece. In order to warrant the beam passage a special workpiece facility is needed with recesses in the base plate. The operational height of the workpiece supporting surface amounts to 950 mm. The contents of marking as specified under the marking task to be performed will be transmitted from the measuring unit by data bus to the marking system. The LasPaint software will transform the incoming data into the desired data matrix formats. The off-products generated by the marking process will be fed off by means of an exhaustion unit with an automatic cleaning function.

CO2 cutting system as an integration solution

Two laser scanner units were mounted on frame construction units under a tangential arrangement to the circular-indexing table of an angle of 105° to each other. 8 clamping units, which position two mobile phone displays each connected by a runner, are mounted on the circular-indexing table of a 600 mm diameter. The loading of the clamping units will take place automatically through a conveying belt. In order to warrant the required cycle time of 1.5 seconds two lasers will be permanently in operation. The programming of the off-set laser scanner units is designed in such a way that the control will recognize the position of the circular-indexing table (1, 2, 3 ... 7 or 8). The coding will be given to the LSE program and the suitable branch mark will be activated.

TL 1220 - CS (Conveying System)

Different workpieces of lot size 1 will be automatically fed to the laser system through a conveying belt that, in addition to more peripheral units, was integrated to master the marking task . A diode-pumped solid-state laser of an average power of 20 watts was selected for the existing marking task. The workpiece that might have any position on the system palette will be fed from the conveying belt to the laser system. Loading of the palettes can be carried out by an industrial robot or manually, resp. By means of a bar code or a data-matrix-code on the system palette or by means of pattern or object recognition the integrated camera and image processing system will identify the type of workpiece and the position of that workpiece on the palette. By calling the suitable software program the XY and C axes will be interpolated according to the actual object position, and the Z-axis interpolation will be performed according to the height of the workpiece. The laser scanner unit will run into its focussing position and the marking process will be started. The marked workpiece will be unloaded through the conveying belt. The process will be continued with the next workpiece.
