Abstract
The invention belongs to a method of laser carving, and in particular relates to a high-speed laser carving method for printing plate making and roller making. The method is characterized by changing single-way laser into multiway carving laser which can be controlled in parallel by adopting a special parallel micro switch mechanism, ensuring high-speed reliable synchronous parallel transfer of carving data by adopting a high-check high-speed interface, and implementing the continuous carving of high-speed real-time large data volume and multi-shaft (X, Y, R) motion compound control through a multi-module automatic exchange device. By applying the method provided by the invention, the multiway laser parallel carving plate making and roller making can be implemented, and the laser plate making and roller making speed can be improved greatly.
Description
Technical field
The invention belongs to a kind of method of laser engraving, particularly a kind of plate making that is used for, the high-rate laser engraving of system roller.
Background technology
Laser carving method in the past, what adopt is the method for single channel laser stepping engraving, during for machining large graining roll, print roller, length expends time in, inefficiency, the invention provides a kind of continuous engraving process of laser of high-speed, multi-path, can increase exponentially the efficient of laser plate-making, system roller.
Summary of the invention
The objective of the invention is: a kind of multi-path laser engraving implementation method of high speed is provided, is applied to plate making, system roller industry improves laser plate-making system roller speed.
Method of the present invention is by strengthening laser power, and the fine motion photoswitch mechanism that employing can be carried out parallel control becomes multichannel with beam of laser and processes, and has increased exponentially working (machining) efficiency.The data-interface of the at a high speed strong verification of employing has simultaneously solved the reliable transmission problem of big data quantity in the parallel processing of multi-path laser, adopt the multimode automatic switching control equipment realized at a high speed, in real time, the continuous engraving control of big data quantity and pair roller edition owner axle rotates, laser along the roller version axially and the control of the interlock between moving radially, become stepping and be processed as continuous processing, improved efficient.
Described laser multichannel processing, be meant that laser sends from laser instrument, through the acousto-optic modulator modulation, be transmitted on one group of micro mirror array as shown in the figure, this micro mirror array comprises several semi-transparent semi-reflecting lens and total reflective mirror, can form multi-path laser parallel, power-sharing by saturating, the counter-function and the deflecting reflection angle of battle array mirror controller control mirror battle array, multi-path laser forms processing request processing laser at interval through a beam expanding lens, and pair roller is ablated.
For satisfying High-speed machining transfer of data and the requirement of control in real time, solve the problem that magnanimity processing engraved data (number GByte) can not once be loaded.Described multimode switching device shifter, the magnanimity Carving Machining data of sending by DMA passage receiving computer, be handed down to three big Capacity FIFO of subordinate respectively, at a high speed strong verification interface also receives the image process data by the DMA passage, is transferred to controlled fine motion array of photoswitch and does laser switch control; The working motion control data is distributed to multiaxis coupled motions controller, according to the requirement of continuous helical processing, to X, Y, R three-axis moving control relevant parameter decompose, decoupling zero, send to relevant controller.Three jumbo FIFO carry out the relay buffer memory to the Carving Machining data of magnanimity, the engraved data that FIFO1 one side receiving computer sends when the FIFO1 internal data is taken in midair, transmit data behind full sky on one side, FIFO2 relay transmission, and FIFO1 waits for after receiving full data.So move in circles, guaranteed that the magnanimity process data continuously is sent to the lower end control section from computer through FIFO1-＞FIFO2-＞FIFO3-FIFO1.
For satisfying the requirement of High-speed machining reliable data transmission, designed at a high speed strong checking data interface, its upper end mainly is that a high speed is received and dispatched the verification controller, comprise big capacity amount buffer memory, verification of hardware high speed logic and sending module, several parts of parallel receive module, large capacity cache sends to verification of hardware high speed logic and sending module with the data block that receives according to the processing beat, this module sends to lower end controlled fine motion photoswitch controller with data parallel (32bit), controller latchs the data that receive, and also adopt parallel mode to send it back and receive and dispatch the verification controller at a high speed, receive by the parallel receive module, the data parallel that latchs in this module sends to and carries out the verification of hardware high speed in verification of hardware high speed logic and the sending module, confirm that the back sends the affirmation order to lower end controlled fine motion photoswitch controller, finishes transmitting-receiving verification at a high speed.

The specific embodiment
The following explanation of concrete enforcement:
Scribble photosensitive material on the roller version, the roller version requires to rotate according to certain rotating speed, a branch of laser that sends by laser instrument, through a parallel fine motion optical switch element, be transformed to the controllable laser of multichannel (more than 2 tunnel), send to the high-speed interface of strong verification behind the pattern digitization that computer will be to be carved, parallel high-speed interface by strong verification is controlled parallel fine motion optical switch element, according to the dependency relation for the treatment of engraving pattern, change the on off state of each road laser, the high photosensitive material of the diverse location on the pair roller version is ablated.Computer is by the automatic switching control equipment of a multimode, the rotating speed of pair roller version (R axle), laser are along roller version moving (Y-axis) and move (X-axis) vertically and carry out the interlock of three axial screws according to the pairing specific rule of the digital file for the treatment of carved image and control radially, cooperate of the control of fine motion optical switch element, finish the continuous engraving of image light.
