LASER PROJECTION FOR POSITIONING TASKS

Placement or alignment guided by laser lines, crosses or points

All reoccurring placement tasks can be supported by laser projection. Depending on shape, position and distinctive characteristics of the object you want to position you may use lines, crosses, points or a combination of these. Lasers for alignment don't touch the surface, so they also work on fragile or sticky materials.

APPLICATION EXAMPLES

SINGLE LINES

SINGLE LINES

Single laser lines can be used if the alignment only has to work for one degree of freedom. This may be a single edge of an object, the hem of textiles, the edge of a sheet of paper, plastics or metal etc., as long as it forms a straight line.   

PARALLEL LINES

PARALLEL LINES

If alignment is only needed in one axis, parallel lines may help to give a visual limit stop and/or define a permitted area for placement. If the width of objects changes, a system with movable laser lines can be used.

PERPENDICULAR LINES, CROSSES

PERPENDICULAR LINES, CROSSES

Rectangular objects may be positioned by projecting a cross or two perpendicular lines. However, the single lines must be long enough in relation to the object to guarantee proper alignment.
Two crosses at opposing corners of a rectangular shape may define the exact position, e.g. of a label.

POINTS AND COMBINATIONS

POINTS AND COMBINATIONS

Laser points can be used to align objects that lack straight or perpendicular outlines. Three points may mark a circular outline. If an object has an irregular outline or distinctive features like grooves, gaps, recesses or mechanical marks, two or more laser points may define the position. Certain tasks may be solved by using combinations of points, lines or crosses.
