Abstract
The present invention relates to devices with which, for example, narrow surfaces of preferably plate-like workpieces can be provided with a coating material. The device includes a laser for outputting a laser beam to a laser beam emitter, wherein the laser beam is directed onto the coating material or onto the workpiece in such a manner that the laser beam forms a plane of reference with solder on the surface of the coating material or the workpiece.
Claims9
A method for activating an adhesive agent provided on a coating material of a workpiece, comprising
- using a movement device to move the coating material or workpiece;
- outputting a laser beam from a laser to a laser beam emitter,
- directing the laser beam to the coating material or the workpiece such that the laser beam forms a plane of reference perpendicular to a surface of the coating material or the workpiece,
- utilizing more p-polarized light than s-polarized light in the plane of reference within the laser beam;
- activating the adhesive agent provided on the coating material with the laser beam,
- and pressing the coating material with a pressure roller onto the workpiece after activation of the adhesive agent, wherein the laser beam forms an angle of 20°-30° in respect to a plane of the coating material or the workpiece.
