Description
Technical field
The utility model relates to a kind of laser system, relates in particular to a kind of laser system that is used for fields such as laser index carving, cutting and welding.
Background technology
Existing a kind of laser system is made up of laser instrument and the control computer that is connected with laser instrument, in the said laser system application process, to different materials and different customer requirements, must regulate and control the power output of laser instrument.
Prior art is through PWM (pulse width modulation) control mode the power output of laser instrument to be controlled, and, because PWM control has only the output signal, can't know the real output and the ruuning situation of laser instrument, so can only realize open loop control.If laser instrument running environment changes, laser power output changes, and computer can't be followed the tracks of adjusting according to these variations, and can't export power accurately.
In actual application, producers must be rule of thumb, Yi Bian change the dutycycle of pwm signal; The Laser Measurement power output often need take a long time adjusting and just make laser instrument export power accurately, in addition on one side; Laser instrument is in running, and the laser output power value has the deviation of 5-10%, for realizing the accurately occasion of control; Such deviation is difficult to meet the demands.
The utility model content
The utility model purpose is to provide a kind of can realize accurately reaching accurate power output, and can realize two closed-loop controls and laser system easy to use.
The utility model provides a kind of laser system, and it comprises: laser instrument and control computer;
Said laser instrument has control panel, laser tube core, spectroscope and built-in power control module, and said laser tube core and said built-in power control module are connected with said control panel respectively;
Said control computer is connected with said control panel.
The said built-in power control module of the utility model can detect the laser power of coming from said spectroscope refraction; And laser power is converted into magnitude of voltage is input to said control panel; Adjust power output through control panel then, thereby realize accurately reaching accurate power output.
In addition, the utility model is through control module automatic power adjustment output valve, and is easy to use, need not manual debugging, thereby can save human resources.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:

The utility model laser system course of work is following:
The light-emitting window of said laser tube core 12 is launched laser radiation behind said spectroscope 14; 99% laser power outputs to the external world; 1% laser power is refracted on the said embedded laser power detection module; Said embedded laser power detection module is converted into magnitude of voltage with laser power and is input to laser instrument control panel 11, and said control panel 11 calculates the real output value of said laser instrument 1 through analog-to-digital conversion and proportionate relationship, and real output value and the digitlization performance number that the control computer passes are down compared; Through special comparison algorithm, adjust the real output value of said laser instrument 1.
Simultaneously; Said control panel 11 can be uploaded to said control computer 2 through Interface for digital communication with real output and duty (like temperature etc.); Said control computer 2 is according to circumstances adjusted control strategy, further controls the work of said laser instrument 1, thereby realizes two closed-loop controls.
In sum, the beneficial effect of the utility model is:
(1), can realize two closed-loop controls to laser instrument, can adjust control mode at any time according to the actual motion state of laser instrument;
(2), the said built-in power control module of the utility model can detect the laser power of coming from said spectroscope refraction; And laser power is converted into magnitude of voltage is input to said control panel; Then through control panel adjustment power output; Thereby realize accurately reaching accurate power output, be applicable to occasion the laser power required precision;
(3), the utility model is through control module automatic power adjustment output valve, and is easy to use, need not manual debugging, reduces manual debugging and operating personnel's workload, increase work efficiency.
More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
