Detailed description of the invention
For enabling above-mentioned purpose, the feature and advantage of the application more become apparent, below in conjunction with the drawings and specific embodiments, the application is described in further detail.
One of core idea of the embodiment of the present application is, by using SOC to galvanometer and the unified control of laser instrument, the motion track of galvanometer is determined by mark point coordinates, the power output of laser is determined by the gray value of each mark point, SOC controls the output timing of laser instrument, makes it match with the motion of galvanometer.
With reference to Fig. 1, show the flow chart of steps of a kind of laser marking machine control method embodiment of the application, wherein, described laser marking machine comprises: system level chip SOC, the laser instrument be connected with described SOC respectively and galvanometer; Specifically can comprise the steps:
Step 101, described SOC receives mark point coordinates and gray value corresponding to mark point;
Step 102, grayvalue transition corresponding with described mark point for described mark point coordinates is become mark instruction by described SOC;
Step 103, described SOC adopts described mark instruction to control the motion of described galvanometer, and controls output timing and the power output of described laser instrument.
Laser marking machine comprises: system level chip SOC (System On Chip), galvanometer and laser instrument.Wherein, SOC also has title SOC(system on a chip), and meaning it is a product, is an integrated circuit having application-specific target, wherein comprises holonomic system and has the full content of embedded software.
SOC is first from the coordinate of mark software receipt mark point and gray value corresponding to mark point in the embodiment of the present application.Mark software processes image to be printed in advance, the resolution that mark software is arranged according to user intercepts pending image, retain the effective pixel points needing to print, and these effective pixel points are packaged into packet, the laser marking machine then sent.SOC is after receiving mark point coordinates and gray value corresponding to mark point, grayvalue transition corresponding with mark point for mark point coordinates is become mark instruction, SOC adopts described mark instruction to control the motion of described galvanometer, and controls output timing and the power output of described laser instrument.Wherein, described mark instruction comprises: mark point coordinates, the performance number that mark point is corresponding; Described step 102 specifically can comprise following sub-step:
The gray value that sub-step S21, described SOC adopt described mark point corresponding calculates performance number corresponding to mark point;
Described mark point coordinates and performance number corresponding to described mark point are combined as mark instruction by sub-step S22, described SOC.
In the embodiment of the present application, the gray value that mark point is corresponding is embodied by the performance number that mark point is corresponding, and the meeting gray value of mark point is less, and image is more black, and the laser output power of needs is higher.
Described SOC comprises: logic main control module, the laser control module be connected with described logic main control module respectively and galvanometer control module; Described step 103 can comprise step quickly:
Sub-step S31, described logic main control module sends performance number corresponding to described mark point according to the time interval of presetting to described laser control module;
Sub-step S32, after the performance number that described mark point is corresponding is sent completely, described logic main control module sends described mark point coordinates to described galvanometer control module;
Sub-step S33, described galvanometer control module controls described galvanometer and moves to described mark point coordinates;
Sub-step S34, after described mark point coordinates is sent completely, whether described logic master control module judges arrives default time delay;
Sub-step S35, if so, then described logic main control module sends output order to described laser control module;
Sub-step S36, described laser control module, after receiving described output order, adopts performance number corresponding to described mark point to control described laser instrument Output of laser.
Mark instruction includes mark point coordinates and performance number corresponding to mark point, SOC is that each effective pixel points of pending image generates a mark instruction, then be stored in the internal memory of SOC by these mark instructions, the determination of mark instruction is the prerequisite that power pointwise controls.
To export the laser of corresponding power in order to realize laser instrument in the position of mark point coordinates, needing the position of the output timing of laser instrument and galvanometer movement to match.Unify to control to galvanometer and laser instrument by SOC.
First the mark instruction be stored in internal memory can be sent to the logic main control module of SOC, then logic main control module sends performance number corresponding to mark point according to the time interval of presetting to laser control module, and the process that the performance number that mark point is corresponding sends can be regarded as completing instantaneously.After the performance number that mark point is corresponding is sent completely, logic main control module sends mark point coordinates to galvanometer control module.The process need regular hour that mark point coordinates sends, the required time can be different according to galvanometer speed.Galvanometer control module, after receiving mark point coordinates, controls galvanometer and moves to described mark point coordinates.
Meanwhile, after mark point coordinates is sent completely, whether logic master control module judges arrives default time delay; If do not arrive, continue to wait for, if reach default time delay, then logic main control module sends output order to laser control module.The process of transmitting of output order can be regarded as completing instantaneously, and laser control module, after receiving output order, adopts the performance number that mark point is corresponding to control laser instrument Output of laser, controls with the pointwise realizing mark point power.
The output timing of laser instrument determined by the time delay preset, and arrives the time delay preset, then sends output order, make laser instrument Output of laser.The reason adopting the time delay preset to control the output timing of laser instrument is, galvanometer can be considered to be the motion that remains a constant speed in whole mark process, therefore by waiting for corresponding time delay, can think that galvanometer reaches mark point.Mating of the output timing of laser instrument and the position of galvanometer movement is realized with this.
Laser instrument Output of laser each time, namely completes the mark of a point.After the mark completing a bit, wait for that logic main control module continues the mark process that mark point power sends, mark point coordinates sends, output order sends, until all marks point all completes mark in the time interval that the next one is preset.The work of galvanometer and laser instrument is carried out according to the transmission timing of instruction completely.
As a kind of preferred exemplary of the present embodiment, described default time delay comprises: accelerate time delay, at the uniform velocity time delay, deceleration time delay; The step whether described logic master control module judges arrives default time delay comprises:
