Abstract
The invention relates to a speed control device for an automatic laser marking machine production line. The speed control device comprises a graphic data partitioning device, a laser system processing time calculating device, and a production line running speed control device, wherein the graphic data partitioning device partitions graphic data to be processed into a plurality of mutually independent graphic modules; the laser system processing time calculating device calculates the required time t for a laser system to process the current graphic module through laser processing path length s in the graphic module and the running speed v of laser spots on a material; and the production line running speed control device calculates the running speed v1 of the production line when the current module is processed on the production line through the length d of the current graphic module on the production line and the processing time t of the laser system. Each graphic module is processed on the production line at the running speed v1 of the production line when the current module is processed, so that the speed of the automatic laser marking machine production line is controlled; and the production line runs at the highest speed when each graphic module is processed, so that the processing efficiency of a laser cutting machine is improved.
Description
[technical field]
The present invention relates to a kind of speed control device for automatic laser marking machine production line and application thereof.
[background technology]
Laser Processing has advantages such as speed is fast, good stability, machining accuracy height, high conformity.Therefore Laser Processing has in recent years replaced multiple processing method, and uses widely in all trades and professions.Such as in textile industry, Laser Processing has just replaced traditional method of cutting out.Use laser to shear and improved the textile working (machining) efficiency greatly.In the prior art, because the galvanometer system process velocity is fast, being applicable to needs high-rate laser processing.Therefore, the galvanometer laser system is used in textile processing usually.Galvanometer system that existing textile laser cutting machine generally comprises a laser instrument, link to each other with laser instrument and the conveyer belt below galvanometer system, conveyer belt is by constant speed operation, mark or cutting on the textile that galvanometer system is in operation.But because figure to be processed is various.When some regional graphics was complicated, the time of laser cutting was more of a specified duration.Cause line speed with matching to descend.But because the conveyer belt operation that remains a constant speed all the time, the process velocity when cooperating the figure complexity, conveyer belt must move under the corresponding speed of conveyer belt when figure is the most complicated.But, greatly reduce production efficiency like this.
Therefore, be necessary to design a kind of speed control device for automatic laser marking machine production line and application thereof, to overcome above-mentioned defective.
[summary of the invention]
The object of the present invention is to provide speed control device for automatic laser marking machine production line, improved streamline overall operation speed, improved the working (machining) efficiency of laser cutting machine.
The invention provides a kind of speed control device for automatic laser marking machine production line, comprise, the graph data partitioning device is cut apart a plurality of separate pattern modules with pattern data to be processed; The laser system processing time arithmetic unit is calculated laser system by Laser Processing path s and the laser facula speed of service v on material in the above-mentioned pattern module and is processed the needed time t of current figure module; The streamline speed control device is calculated the speed of service v1 of streamline when processing when front module by current figure module in length d on the streamline and laser system processing time t; Streamline all by when front module streamline speed of service v1 operation, with this, carries out the control of automatic laser marking machine production line speed when each pattern module of processing.
The present invention also provides a kind of automatic laser marking machine, and described laser marking machine has above-mentioned speed control device for automatic laser marking machine production line.
A kind of streamline automatic laser marking method, it is characterized in that this method may further comprise the steps: feeder is delivered to material on the workbench; Computer is cut apart a plurality of separate pattern modules with pattern data to be processed; Computer calculates laser head and processes each time of needing of pattern module independently; Computer is according to each speed of service of time of pattern module needs and each streamline when independently the length of pattern module on streamline is calculated this module of processing independently; The corresponding pattern module speed of service operation that streamline is calculated among the d set by step, laser head is processed corresponding pattern module simultaneously.
Compared with prior art, because the figure that the present invention will process whole streamline by the graph data partitioning device is divided into the figure module of several independent, set the processing needed time of this module respectively according to the figure complexity on each module then, the speed of streamline when setting the current figure module of processing according to this time.Make streamline when processing each figure module, all keep the highest speed by moving laser marking machine production line speed control unit, the problem of losing time of having avoided the constant streamline of prior art medium velocity to bring has improved the working (machining) efficiency of laser cutting machine.
