Laser marking machine control method and laser marking machine

Abstract

An embodiment of the invention provides a laser marking machine control method. A laser marking machine includes a system-on-a-chip (SOC), and a laser and a galvanometer which are connected with the SOC; and the SOC includes a CPU and a logical unit which are connected with a data bus through a control bus. The method includes the following steps: a CPU receives an image to be processed, and uses the image to be processed to generate control instructions and control parameters; and the logical unit controls the galvanometer and the laser according to the control instructions and the control parameters. The laser marking machine control method realizes control of the laser marking machine through the SOC integrating modules, information data integrated in the modules of the SOC can be mutually shared, and in addition, the information data in the modules can be management in a unified manner, thereby realizing overall control and overall monitoring of the laser marking machine.

Description

technical field [0001] The present application relates to the technical field of laser control, in particular to a method for controlling a laser marking machine and a laser marking machine. Background technique [0002] refer to figure 1 Shown is the structural block diagram of the existing laser marking machine, which is mainly composed of four modules: PC, motion control board, laser and vibrating mirror. Each module has its own main control unit, that is to say, each module There is a main control unit similar to a CPU, and the four modules use traditional external interfaces for communication, the PC and the motion control module use USB for communication, and the motion control module communicates with the laser and the galvanometer using the DB interface. [0003] Its working principle is that the PC converts the edited graphics or text into a certain form of control commands and sends them to the motion control board. The motion control board parses the control comm...

Problems solved by technology

[0004] The marking system composed in this way has several disadvantages that cannot be avoided: first, each functional module has its own main control module, and the modules are completely connected in the form of black boxes to work, and the internal data cannot be Second, a single external interface is used for communication between modules. Therefore, control information and marking content data share a data bus interface. When the amount of marking content data is large, the bus will be occupied for a long time and the control will be blocked. The final result of the transmission of information is that it cannot be prohibited by order; third, the data of each module cannot be managed uniformly, and the overall control and overall monitoring of the laser marking machine cannot be achieved.
