Description

Automatic adjustment mechanism of operating parameters of laser marking machine

This work is about laser marking, especially an automatic adjustment mechanism for operating parameters of a laser marking machine.

The laser marking machine uses the laser beam to be highly focused after being processed by the lens, and then applies the laser beam to the laser processing object to achieve the purpose of marking, material removal, cutting or engraving. Generally, the marking object is placed on a slide table. Then use the motor system to control the movement and rotation of the sliding table, and move the sliding table to a position suitable for marking to perform marking operations. Among them, the computer device first calculates the marking coordinates, and then controls the laser marking machine for marking.

Various parameters must be set when the laser marking machine is enabled, so that the settings of the internal components of the laser marking machine meet the needs of use. The setting of these parameters is usually set by the user according to the experience value, and then continuously corrected after the marking test, so as to obtain the quality required by the user. In most cases, users do not understand the actual physical meaning of these parameters and the relationship between actual components, so they cannot understand the impact of these parameters on the marking pattern. Allow users to input these parameters by themselves. Users input these parameters without knowing the final effect at all. Therefore, users often spend a lot of testing time and marking times, and learn through exploration before they can get better markings. The effect, or the user did not make effective parameter planning and testing, so the best marking parameters were not obtained in the end.

Therefore, this case hopes to propose a brand-new automatic adjustment mechanism for the operation parameters of the laser marking machine, which allows the user to automatically adjust the parameters of the laser marking machine without inputting these parameters, so as to To solve the above-mentioned defects in the prior art.

The purpose of this creation is to solve the above-mentioned problems in the conventional technology. In this creation, an automatic adjustment mechanism for operating parameters of a laser marking machine is proposed. Applying the automatic adjustment mechanism of the laser marking machine operating parameters in this case, the system can set the appropriate parameters according to the graphics selected by the user and rely on the logic of finding the best parameters. The user does not need to understand the physical meaning of the parameters and the interaction between these parameters and the actual mechanism, but only needs to point out which sample is the best marking result among the graphs of several different parameters generated by the mechanism. Moreover, fine-tuning can be used to further achieve the purpose of setting the best parameters. It can save the time required for the user to set the parameters of the laser marking machine, greatly improve the efficiency of the laser marking machine, and reduce the troubles of the user during the initial operation.

In order to achieve the above purpose, this creation proposes an automatic adjustment mechanism for laser marking machine operating parameters, which is applied to a laser marking machine, including: a computer device, according to the position and marking of each laser marking machine The direction determines the entire marking space. The computer device includes the following components: a user interface for interacting with the user; a marking calibration mechanism connected to the at least one laser marking controller and the user interface, the marking calibration mechanism according to default parameters Plan the corresponding multiple calibration plans and send them to the corresponding laser marking controller to control the corresponding laser marking machine. a calibration marking diagram; wherein the marking calibration mechanism includes: a calibration pattern generator, which plans out the multiple calibration planning diagrams according to default parameters, and the calibration pattern generator uses the marking parameters of each of the calibration planning diagrams ( Including coordinates), input the corresponding laser marking controller, so that the corresponding laser marking machine can mark the marking object; a parameter adjuster is connected to the calibration pattern generator, according to the pattern selected by the user Like, find out the corresponding parameter, and then adjust this parameter to get a new set of parameters, and input these new parameters into the corresponding laser marking controller, so that the corresponding laser marking machine can The marking object is marked. This operation can be carried out repeatedly to adjust the parameters satisfactory to the user.

One of the operation modes is a single parameter operation mode, that is, only one parameter is adjusted each time. The calibration pattern generator comprising the operation steps of the laser marking machine displays a plurality of calibration planning diagrams on the marking object so that the user can select the most satisfactory marking pattern (step 700); the user interface receives and uses The most satisfactory calibration map selected by the user (step 710); if the user is satisfied with the result, adjust the parameter of the laser marking to this value for future operation (step 720); if the user is satisfied with the result If the result is unsatisfactory, the parameter is further fine-tuned, and the parameter adjuster adjusts at a finer interval around the selected parameter to obtain a new set of fine-tuning parameters (step 730). According to the new fine-tuning parameters calculated by the parameter adjuster, the calibration pattern generator plans a plurality of new parameter calibration planning diagrams (step 740), allowing the user to select his favorite graphics; the user interface then Receive the most satisfactory calibration map selected by the user for future operation (step 750); if necessary, this step can be repeated for further fine-tuning until the user is satisfied with the result, or in a set This operation is stopped after the number of times, and the parameter of the laser marking is adjusted to this value for future operation (step 760); and in steps 720 and 760, the obtained parameters are stored in the memory 160 (step 770).

Another mode of operation is to calibrate a (group) of parameters that should be matched when marking the graphics by selecting different graphics by the user. Different graphics represent the overall setting of this group of parameters. If fine-tuning is required, the parameter adjuster fine-tunes this group of parameters as a whole according to the default setting or the default algorithm, and then generates another set of fine-tuning parameters, and obtains a new calibration plan based on the fine-tuning parameters for the user to choose .

FIG. 1 shows a schematic diagram of a laser marking machine 10 and a laser marking controller 60 configured in this case. Figure 2 shows a schematic diagram of the graphic generation and configuration relationship between the laser marking machine and the laser marking controller configured in this case.

A computer device 50, according to the position and marking direction of each laser marking machine 10, determines the entire marking space and the space coordinates of the slide table 20.

The computer device 50 can mark the two-dimensional figure of the entire marking space, and receive the marking figure 40 input by the user, and calculate the corresponding marking figure 40 according to the geometric position of the marking figure 40 in the two-dimensional space. It should be the point coordinates in 2D space. The computer device 50 transmits the point coordinates in the two-dimensional space to the outside. The computer device 50 includes the following components:

A user interface 150 can interact with the user, so that the user can operate the computer smoothly to achieve the purpose of setting the laser marking machine 10 .

A marking correction mechanism 70 is connected to the at least one laser marking controller 60 . The marking calibration mechanism 70 plans corresponding multiple calibration plans 711 according to default parameters, and transmits them to the corresponding laser marking controller 60 to control the corresponding laser marking machine 10. Planning diagram 711 , a plurality of calibration planning diagrams 711 are formed on the marking object 100 .

Wherein the marking correction mechanism 70 includes:

A correction pattern generator 71 plans out the plurality of correction plans 711 according to default parameters. The correction plan is shown in FIG. 3A, for example, wherein the correction plan 711 is a two-dimensional figure of a plurality of rectangles (this is for illustrative purposes, not intended to limit the scope of the present invention), and these rectangles are composed of different Generated by setting parameters; or as shown in FIG. 3B , the correction plan graph 711 may also be a graph formed by crossing each horizontal line with a single straight line. The calibration pattern generator 71 can be implemented using software or hardware components.

The calibration pattern generator 71 inputs the coordinates of each calibration plan 711 into the corresponding laser marking controller 60 , so that the corresponding laser marking machine 10 can mark the marking object 100 .

In this case, a camera 72 may be included for taking pictures of each calibration marking pattern 110 on the marking object 100, and sending the captured image graphics 721 to the outside.

A parameter adjuster 73 is connected to the calibration pattern generator 71 according to the user's selection image, find out its corresponding parameter, and then adjust this parameter to obtain a set of new parameters, and input these new parameters into the correction pattern generator 71 to generate a new correction planning map 711. This operation can be carried out repeatedly to adjust the parameters satisfactory to the user. The parameter adjuster 73 can be implemented using software or hardware components.

This case can have two operation modes, one is a single parameter operation mode, wherein the calibration pattern generator 71 of the laser marking machine 10 displays a plurality of calibration plans 711 on the marking object 100 for selection by the user Please refer to FIG. 5 for the most satisfactory marking pattern (step 700 ).

The plurality of calibration planning diagrams 711 are parameters that need to be controlled during laser marking, and the parameters are adjusted to generate the plurality of calibration planning diagrams 711 . These parameters are such as marking frequency, starting position of laser emission, stop position of laser emission, marking speed, marking power, maximum frequency, minimum frequency, pulse width and so on.

Among the plurality of calibration planning diagrams 711 , the user interface 150 receives the most satisfactory calibration planning diagram 711 selected by the user (step 710 ), indicating that the user accepts the parameters related to the diagram. The parameter of the laser marking can be adjusted to this value for future operation (step 720). In this case, the parameter can also be further fine-tuned. For example, if the parameter indicates the marking frequency, then the laser marking frequency can be adjusted to the vicinity of this frequency. For example, the interval between the frequencies at the beginning is 1 unit, and the frequencies tested are 1, 2, 3, 4, 5, 6, and 7 units respectively. When the user selects the unit 4 as a satisfactory transmission frequency, the user inputs the selected graphic through the user interface 150, and then the marking correction mechanism 70 further fine-tunes the parameter, and the parameter adjuster 73 is in the position A set of fine-tuning parameters is obtained by adjusting at a finer interval around the selected frequency (ie, the parameter) (step 730 ), for example, changing the frequency interval to 0.1 unit. Then set the frequency of the emitted laser to 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3 units. According to the new units (new fine-tuning parameters) calculated by the parameter adjuster 73, the calibration pattern generator 71 plans out the multiple new calibration planning diagrams 711 (step 740), and then allows the user to choose the one he likes. graphics, the user The interface 150 then receives the most satisfactory calibration map 711 selected by the user for future operation (step 750 ). If necessary, this step can be repeated for further fine-tuning until the user is satisfied with the result, or stop this operation after a set number of times, and adjust the parameter of the laser marking to this value for future use. For operation (step 760). In steps 720 and 760, the obtained parameters are stored in the memory 160 (step 770).

Another operation mode in this case is the multi-parameter operation mode. Its operation steps are the same as the above-mentioned single-parameter operation mode. However, many parameters are interactive during parameter setting, so they must be set in groups, that is, a calibration plan. 711 represents the integration result of multiple parameters, so when the user selects a currently satisfactory calibration plan 711 , it represents setting a set of parameters. If fine-tuning is required, the parameter adjuster 73 fine-tunes these parameters as a whole according to default settings or default algorithms, and then generates another set of calibration plans 711 for the user to select. For example, during laser marking, the laser emitter and the vibrating mirror must be controlled, and the control of the relative position is mainly calculated by a set of control equations, which are handed over to the correction pattern generator 71 of the laser marking machine. And the parameter adjuster 73 generates the calibration map 711 for the user to select. The set of control equations contains multiple parameters, which are interrelated.

The following describes a correction example of this case and please refer to Figure 4, where the original parameters for marking are set, these parameters include marking speed, marking power, maximum frequency of laser pulse wave emission, minimum laser pulse wave emission Frequency and pulse width of laser pulse wave. These parameters are related to the emission of the laser pulse and will affect the quality of the marking line. Therefore, at the beginning, the calibration pattern generator 71 plans out the plurality of calibration planning diagrams 711 according to a set of default parameters, and then the user selects the most satisfactory calibration planning diagram 711 through the user interface 150, indicating that the user accepts A set of parameters associated with this graph. Then adjust the group of parameters of the laser marking to this value, and further fine-tune the group of parameters according to the default algorithm, and input these fine-tuned parameters into the correction pattern generator 71 to generate a plurality of new Calibrate the planning map 711, and then let the user choose the one he likes graphics. This step can be repeated for further fine-tuning if desired.

The advantage of this case is that the automatic adjustment mechanism of the operating parameters of the laser marking machine of this case is used, and the user can find the best parameters according to the selection of the graphics. The user does not need to understand the physical meaning of the parameters and the interaction between these parameters and the actual mechanism, but only needs to select the graphics generated by the mechanism. The purpose of parameter setting can be further achieved through fine-tuning, which saves the time required by the user for the setting operation of the laser marking machine, and can also find a better parameter setting method. It greatly improves the efficiency of the laser marking machine and reduces the user's troubles during the initial operation.

To sum up, the humanized and thoughtful design of this case is quite in line with actual needs. Its specific improvement has existing deficiencies, and compared with the prior art, it has the advantage of breakthrough progress, and indeed has the enhancement of efficacy, and it is not easy to achieve. This case has not been published or disclosed in domestic and foreign literature and market, which is in compliance with the provisions of the patent law.

The above detailed description is a specific description of a feasible embodiment of this creation, but this embodiment is not used to limit the patent scope of this creation, and any equivalent implementation or change that does not deviate from the spirit of this creation should be included in the In the patent scope of this case.
