Abstract: Method of controlling a laser marking matrix system, the matrix system comprising an N×M matrix of lasers to produce the laser marking, the method comprising the sequential transformation of at least two images to be marked into a series of marking commands according to an N×M matrix of dots, which comprises the following phases: division of a first image into a fixed portion and a variable portion, transformation of the fixed portion into a fixed matrix and the variable portion into a variable matrix, combination of said fixed and variable matrices, laser marking of the first image, processing of a second image, obtaining a new variable matrix which is added to the previous fixed matrix, producing a complete new matrix, laser marking of the second image.

Abstract: Method of producing equipment for marking products by laser, comprising the steps of: having at least one base plate; having various types of modules in which equipment components are grouped; having casings, rear covers and front covers that can be attached to said base plate; selecting modules from each of the different module types; removably attaching the selected modules to the base plate; attaching the casing, rear cover and front cover to the base plate.

Abstract: Device and process for marking a moving object by laser A process for marking a moving object by means of a laser using a laser system with a laser beam with the ability to mark within a working area characterised in that: the position of the object to be marked is obtained by means of a sensor, and the speed of the object to be marked is varied in relation to the position of the object to be marked relative to the working area and/or the position of the laser beam within the working area.

Abstract: A laser apparatus includes a base frame extruded in one single piece of light alloy metal which determines a chamber intended to receive the laser generator cavity, incorporated within the chamber. The plane of the lower base of the chamber coincides with the base plane of the extruded base, and the lateral faces of the chamber are directed towards opposed lateral faces of partition walls of the extruded base, with controlled clearance to permit the expansion of the laser generator cavity without mechanical stresses being produced on same, capable of deforming it.

Abstract: A laser marking system includes a means for generating a laser beam and a marking control unit which generates individual signals applied to a laser system for producing an N×M matrix of dots used to mark an object. Each dot is created from the laser light from at least one laser diode. If multiple lasers are used, their power can be combined with a concentrator to produce a single beam with a higher power and also provide for simplified control over the beam's power.
