Description

The present invention is a method for setting a laser processing device, a laser processing data setting device, and a laser processing device for setting processing conditions in a laser processing device such as a laser marking device that irradiates a processing object with a laser beam to perform processing such as printing. , Laser processing condition setting program, computer-readable recording medium and recording equipment.

The laser processing apparatus scans the laser beam within a predetermined region and irradiates the surface of the object to be processed (work) such as a part or product with the laser beam to perform processing such as printing and marking. An example of the configuration of the laser processing apparatus is shown in FIG. The laser processing apparatus 1001 shown in this figure includes a laser control unit 1002, a laser output unit 1003, and an input unit 1004. The excitation light generated by the laser excitation unit 1005 of the laser control unit 1002 is irradiated to the laser medium 1007 constituting the oscillator by the laser oscillation unit 1006 of the laser output unit 1003 to cause laser oscillation. The laser oscillation light is emitted from the emission end face of the laser medium 1007, the beam diameter is expanded by the beam expander 1008, reflected by the optical member 1009, and guided to the scanning unit 1010. The scanning unit 1010 reflects the laser light LB and polarizes it in a desired direction, and the laser light LB output from the condensing unit 1011 is scanned on the surface of the work WK to perform processing such as printing.

In such a laser marking device, the ideal print position and print line segment set in advance may be slightly deviated from the desired position due to the inertia of the galvano scanner motor and the mirror, the control tracking delay, and the like. When writing the same print repeatedly or printing that changes according to a certain rule, for example, in a grid pattern on a device with such characteristics, the print speed is adjusted to solve the misalignment. It was dropped or a waiting time until printing was provided before each element.

If one printing unit is at the level of several, it can be dealt with by setting the waiting time individually or setting the same waiting time for all, but it becomes a large number such as 100 × 100 and 1000 × 1000. When it comes, the amount of work becomes enormous. That is, it is difficult to set an appropriate value individually, but if the same value is set for all print items, there is a problem that the printing time becomes excessive.

It is also conceivable to automatically set the waiting time according to the distance from the previous printing unit to the next printing unit, but even in this case, the performance of the scanner varies, and the X scanner or Y depends on the direction of the marking device. Even with this method, the optimum settings could not be made because the load on the scanner changes.

Furthermore, regarding print misalignment, there are print misalignments that can be tolerated by the user and those that are not, so settings that shorten the print time while allowing a certain amount of print misalignment, especially when there are many print units. Could not be done properly.

Even if the waiting time was set for each print unit by taking time and effort, it was not possible to make a proper setting unless the setting was made while actually printing and checking many times.

(Construction of laser processing equipment)

The laser processing apparatus scans the laser beam within a predetermined region and irradiates the surface of the object to be processed (work) such as a part or product with the laser beam to perform processing such as printing and marking. An example of the configuration of the laser processing apparatus is shown in FIG. The laser processing apparatus 100 shown in this figure irradiates the laser medium 8 constituting the oscillator with the excitation light generated by the laser light generation unit 6 of the laser control unit 1 by the laser oscillation unit 50 of the laser output unit 2 to generate a laser. Causes oscillation. The laser oscillation light is emitted from the emission end face of the laser medium 8, and as shown in FIG. 2, the beam diameter is expanded by the beam expander 53 and guided to the laser light scanning unit 9. The laser light scanning unit 9 reflects the laser light LB and polarizes it in a desired direction, and the laser light LB output from the condensing unit 15 is scanned on the surface of the work WK to perform processing such as printing.

The laser processing apparatus 100 includes a laser light scanning unit 9 as shown in FIGS. 1 and 2 in order to scan the laser light LB on the work WK. The laser light scanning unit 9 includes XY-axis scanners 14a and 14b constituting a pair of galvano mirrors, and galvano motors 51a and 51b for fixing and rotating each galvano mirror to a rotation axis, respectively. .. As shown in FIGS. 1 and 2, the X / Y axis scanners 14a and 14b are arranged in a posture orthogonal to each other, and the laser beam LB can be reflected in the X direction and the Y direction for scanning. Further, as shown in FIG. 1, a condensing unit 15 is provided below the laser light scanning unit 9. The condensing unit 15 is composed of a condensing lens for condensing the laser beam LB so as to irradiate the working area, and an fθ lens or a telecentric lens is used.

The above FIGS. 1 and 2 show an example of a laser processing apparatus that scans and processes a laser beam LB in a two-dimensional plane. However, the present invention is not limited to this configuration, and can be used for a laser processing apparatus capable of three-dimensional processing by adjusting the focal length of the laser beam LB in the Z-axis direction (height direction). FIG. 3 shows, as an example of such a laser processing apparatus capable of three-dimensional processing, a laser processing apparatus capable of changing the focal length by adding a Z-axis scanner 14c. As shown in FIG. 3, the Z-axis scanner 14c includes an incident lens facing the incident side (oscillating portion 50 side) of the laser beam and an emitting lens facing the laser emitting side, and the lens is driven by a drive motor or the like. The distance between the lenses is relatively changed by sliding, and the focal length, that is, the working distance in the height direction can be adjusted. As a result, as shown in FIG. 4, the laser beam LB can be scanned in the processing area WA, and the focal position in the height direction can be adjusted.
(Input unit 3)

The input unit 3 shown in FIG. 1 is connected to the laser control unit 1, inputs necessary settings for operating the laser processing device 100, and transmits the necessary settings to the laser control unit 1. The setting contents include operating conditions of the laser processing apparatus 100, printing patterns such as specific character strings and symbols, and adjustment information (adjustment values, etc.) for the fed-back printing result. The input unit 3 is an input device such as a keyboard, a mouse, and a console. Further, it is also possible to separately provide a display unit 82 for confirming the input information input by the input unit 3 and displaying the state of the laser control unit 1 and the feedback processing schedule information and processing result.
(Display unit 82)

As the display unit 82 shown in FIG. 1, a monitor such as an LCD or a cathode ray tube can be used. Further, if the touch panel method is used, the input unit and the display unit can also be used. As a result, the necessary settings of the laser processing device can be made in the input unit and display unit without externally connecting a monitor or the like. Alternatively, a dedicated console or a wirelessly connected tablet can be used as an input unit or a display unit.

For example, the display unit 82 displays the first locus FT and the second locus ST side by side, superimposes the first locus FT and the second locus ST, or displays the first locus FT and the second locus ST. Can be switched and displayed (details will be described later).
(Laser control unit 1)

The laser control unit 1 shown in FIG. 1 includes a laser light control unit 4, a memory unit 5, a laser light generation unit 6, and a power supply 7. The memory unit 5 records the setting contents input from the input unit 3. The laser light control unit 4 reads the set contents from the memory unit 5 when necessary, operates the laser light generation unit 6 based on the print signal corresponding to the print pattern, and excites the laser medium 8 of the laser output unit 2. A semiconductor memory such as RAM or ROM can be used for the memory unit 5. In addition to being built in the laser control unit 1, the memory unit 5 can also use a semiconductor memory card such as a removable PC card or SD card, or a memory card such as a card-type hard disk. The memory unit 5 composed of a memory card can be easily rewritten by an external device such as a computer. By writing the contents set by the computer into the memory card and setting it in the laser control unit 1, the input unit 3 is lasered. The setting can be performed without connecting to the control unit 1. In particular, semiconductor memory is fast in reading and writing data, and has no mechanical operating parts, so it is resistant to vibration and the like, and it is possible to prevent data loss accidents due to crashes like hard disks.
(Laser light control unit 4)

The laser light control unit 4 operates the laser light scanning unit 9 of the laser output unit 2 in order to scan the laser light LB oscillated by the laser medium 8 on the print target (work) WK so as to perform the set printing. The scanning signal to be generated is output to the laser light scanning unit 9. The power supply 7 applies a predetermined voltage to the laser light generating unit 6 as a constant voltage power supply. The print signal that controls the print operation is a PWM signal corresponding to one pulse of the laser light LB in which the laser light LB is switched ON / OFF according to the HIGH / LOW and one pulse is oscillated. The laser intensity of the PWM signal is determined based on the duty ratio according to the frequency, but the laser intensity may also be changed depending on the scanning speed based on the frequency.

Further, the laser light control unit 4 controls ON / OFF of the laser light generation unit 6 based on the emission timing data of the laser light LB. The laser light control unit 4 has a print pattern set as an initial value, for example, an angle signal and deviation signal fed back from the laser light scanning unit 9, and emission timing data of the laser light LB fed back from the laser light detection unit 70. The print result generated based on the above is controlled to be output to the display unit 82 and the memory unit 5 without actually laser marking the print target (work) WK (details will be described later).
(Laser light generator 6)

The laser light generating unit 6 includes an optically bonded laser excitation light source 10 and a laser excitation light source condensing unit 11. The laser light generating unit 6 fixes the laser excitation light source 10 and the laser excitation light source condensing unit 11 in the laser light generating unit casing. The laser light generating unit casing is made of a metal such as brass having good thermal conductivity, and efficiently dissipates heat to the outside of the laser excitation light source 10. The laser excitation light source 10 is composed of a semiconductor laser, a lamp, or the like.
(Laser output unit 2)

The laser output unit 2 includes a laser oscillation unit 50. The laser oscillating unit 50 that generates the laser light LB includes a laser medium 8, an output mirror and a total reflection mirror arranged so as to face each other at a predetermined distance along the optical path of the stimulated emission light emitted by the laser medium 8. It is equipped with an aperture, a Q-switch 19 and the like arranged between. The stimulated emission light emitted by the laser medium 8 is amplified by multiple reflections between the output mirror and the total reflection mirror, and the mode is selected by the aperture while being interrupted in a short cycle by the operation of the Q switch 19 and output. The laser beam LB is output through the mirror. The method of pulsing is not limited to the Q switch, and for example, the LD that becomes the seed light may be pulse-oscillated by the pulse generator.

The laser output unit 2 shown in FIG. 1 includes a laser medium 8 and a laser light scanning unit 9. The laser medium 8 is excited by the laser excitation light incident from the laser light generating unit 6 via the optical fiber cable 13 and laser oscillates. The laser medium 8 employs a so-called end-pumping excitation method in which laser excitation light is input from one end face of a rod shape to be excited, and laser light LB is emitted from the other end face.
(Laser light detection unit 70)

As the laser light detection unit 70 shown in FIG. 1, for example, a photodetector using a photodiode (Photodiode) can be used. Such a laser light detection unit 70 detects the emission timing of the laser light LB from the laser light generation unit 6. The laser light LB from the laser light generating unit 6 is branched into a laser light detecting unit 70 direction and a laser light scanning unit 9 direction by a half mirror 62 arranged on the optical path. The emission timing of the laser light LB actually generated from the laser light generation unit 6 is obtained as emission timing data by detecting the laser light LB branched via the half mirror 62 by the laser light detection unit 70.

The laser light detection unit 70 generates a signal that matches the emission timing of the pulsed laser light LB emitted from the laser oscillation unit 50. Feedback control is enabled by outputting the generated emission timing data to the laser beam control unit 4.
(Shutter unit 71)

The shutter unit 71 is a member for switching between a state in which the laser beam is passed and a state in which the laser beam is blocked. As shown in FIG. 1, the shutter portion 71 is provided on the optical path of the laser beam LB. The shutter unit 71 is opened, for example, by inserting a shutter that blocks the optical path into the optical path to enter the blocking state, and moving the shutter so as to exclude it from the optical path. When performing laser marking, the shutter unit 71 opens the shutter, passes the laser light LB that has reached the shutter unit 71, and irradiates the work WK with the laser light LB. On the other hand, when adjusting the processing pattern of laser processing or the like, when it is not desired to output the laser light while oscillating it, a shutter is inserted on the optical path so that the laser light cannot pass through the shutter portion 71.

The shutter opening / closing operation by the shutter unit 71 sets the shutter unit 71 in a shutoff state in a normal state, and switches to an open state when laser marking is executed. On the contrary, the shutter portion 71 may be opened in the normal state and operated so as to be closed when adjusting the processing pattern of laser processing. When the laser light LB is not generated from the laser light generation unit 6, the shutter unit 71 can be omitted. Such an example is shown in FIG. 5 as a modification 1.
(Modification example 1)

In the above-described embodiment, the emission timing of the laser light LB is calculated using the ON / OFF signal of the actual laser light LB received from the laser light detection unit 70. However, the present invention is not limited to this configuration, and for example, the emission timing of the laser beam LB may be calculated from the laser output signal pulse given to the Q switch in the laser oscillator 50. Further, a table of measured values of the emission timing of the laser light LB with respect to the output of the laser light generation unit 6 is stored in the memory unit 5, and the laser light control unit 4 reads out the table at any time to reflect the output response delay. You can also get the timing. By such a method, it is possible to obtain the emission timing without actually emitting the laser light LB from the laser light generation unit 6. Therefore, it is possible to omit the laser light detection unit and the shutter unit as in the laser processing apparatus 100'shown in FIG.
(Laser light scanning unit 9)

As shown in FIG. 1, the laser light scanning unit 9 is arranged in a posture orthogonal to each other. An example of a digital galvano scanner that constitutes a pair of digital galvano mirrors that reflect laser light in the X and Y directions to enable scanning is shown in the perspective view of FIG. The digital galvano scanner shown in this figure is an angle between an X-axis scanner 14a constituting a digital galvano mirror, a digital galvano scanner motor 51a for fixing and rotating the X-axis scanner 14a on a rotation axis, and a digital galvano mirror. The scanning angle detection unit 72a for detecting the above is provided. The rotational operation of this digital galvano scanner is controlled by the scanner drive circuit 52 shown in FIG. 1 and the like. Specifically, the digital galvano scanner driver included in the scanner drive circuit 52 controls the X-axis scanner 14a and the Y-axis scanner 14b, respectively (details will be described later in FIG. 7). In the example of FIG. 6, the digital galvano mirror on the X-axis side has been described, but the Y-axis scanner 14b, the digital galvano scanner motor 51b, and the scanning angle detection unit 72b that constitute the digital galvano mirror on the Y-axis side can also be configured in the same manner. ..

For the scanning angle detection unit 72, for example, an optical rotary encoder can be used. The optical rotary encoder consists of a scale disk connected to the motor shaft and an encoder device arranged on the stator side. The scanning angle detection unit 72 detects the angle of the digital galvanometer mirror, and outputs the detected angle as two analog signals having orthogonal phases, with one grating of the scale as one wavelength.

The control configuration by the digital galvano scanner driver 73 is shown in FIG. As shown in this figure, the digital galvano scanner driver 73 includes an A / D circuit 731, an angle signal processing circuit 732, a controller 733, a D / A circuit 734, and a current control amplifier 735. The digital galvano scanner driver 73 uses the angle signal detected by the scanning angle detection unit 72 as a feedback signal and drives the digital galvano scanner motors 51a and 51b according to the input angle command signal.

The digital galvano scanner driver 73 inputs the angle command signal output from the controller 74, and performs feedback control so as to follow the mirror to the corresponding angle. Specifically, after converting the two analog signals output from the scanning angle detection unit 72 into digital signals by the A / D circuit 731, the angle signal processing circuit 732 generates an angle signal according to the mirror angle. A deviation signal is generated by calculating the difference between the angle signal and the angle command signal input from the controller 74. In this way, the digital galvano scanner driver 73 performs processing with a digital signal. By such digital processing, processing with low noise and high reproducibility can be performed.

The digital galvano scanner driver 73 inputs the obtained deviation signal to the controller 733 to generate a current command signal for driving the digital galvano scanner motors 51a and 51b, and uses the obtained current command signal as a D / A circuit. It is input to 734, converted into an analog signal, and the digital galvano scanner motors 51a and 51b are driven by the current control amplifier 735. The present invention does not limit the control method for driving the motor to the above, and other known control methods can be appropriately used. For example, the motor may be driven by a PWM signal without D / A conversion.

Further, the digital galvano scanner driver 73 uses the angle signal and the deviation signal generated with low noise by the above-mentioned digital processing for driving the digital galvano scanner motors 51a and 51b, and the laser beam of the laser control unit 1. By outputting to the control unit 4, the virtual machining according to the present embodiment is realized (details will be described later). The present invention is not only a laser processing apparatus that performs processing in a two-dimensional plane, but also a laser processing apparatus that enables three-dimensional processing by adjusting the focal distance of the laser beam in the Z-axis direction (height direction). Is also applicable.
(Laser medium 8)

In the above example, a rod-shaped Nd: YVO ₄ solid-state laser medium was used as the laser medium 8. The wavelength of the excitation semiconductor laser of the solid-state laser medium was set to 809 nm, which is the center wavelength of the absorption spectrum of Nd: YVO ₄ . However, not limited to this example, as other solid-state laser media, for example, rare earth-doped YAG, LiSrF, LiCaF, YLF, NAB, KNP, LNP, NYAB, NPP, GGG and the like can also be used. Further, the wavelength of the output laser beam LB can be converted to an arbitrary wavelength by combining the solid-state laser medium with a wavelength conversion element. It can also be applied to a so-called fiber laser in which a fiber is used as an oscillator instead of a bulk as a laser medium.

Further, it is also possible to use a wavelength conversion element that does not use a solid-state laser medium, in other words, does not form a resonator that oscillates laser light, and performs only wavelength conversion. In this case, wavelength conversion is performed on the output light of the semiconductor laser. Wavelength conversion elements include, for example, KTP (KTiPO ₄ ), organic nonlinear optical materials and other inorganic nonlinear optical materials such as KN (KNbO ₃ ), KAP (KAsPO ₄ ), BBO, LBO, and bulk polarization inversion elements (bulk type polarization inversion elements). LiNbO ₃ (Periodically Polled Lithium Niobate: PPLN), LiTaO _3, etc.) can be used. It is also possible to use a semiconductor laser for an excitation light source of a laser by up-conversion using a fluoride fiber doped with rare earths such as Ho, Er, Tm, Sm, and Nd. As described above, in the present embodiment, various types can be appropriately used as the laser generation source.
(Laser oscillator 50)

The laser oscillating unit 50 is not limited to a solid-state laser, and a gas laser using a gas such as CO ₂ , helium-neon, argon, or nitrogen as a medium can also be used. For example, when a carbon dioxide laser is used, the laser oscillator has a carbon dioxide (CO ₂ ) filled inside the laser oscillator and has a built-in electrode. The laser oscillator oscillates based on the printed signal given by the laser oscillator. The carbon dioxide gas in the part 50 is excited and laser oscillated.

For example, one computer may integrate a function as a laser processing condition setting device 180 and a function as a controller of a marking head provided with a laser output unit. Further, the laser processing condition setting device 180 may be configured as a separate member from the laser processing device, or may be integrated into the laser processing device, for example, a laser processing condition setting circuit incorporated in the laser processing device.

Further, various external devices 190 can be connected to the controller unit 1A as needed. For example, an image recognition device such as an image sensor that confirms the type and position of the work WK transported on the line, a distance measuring device such as a displacement meter that acquires information on the distance between the work WK and the marking head unit 150, and a predetermined A PLC that controls the equipment according to the sequence, a PD sensor that detects the passage of the work WK, and various other sensors can be installed and connected to these by data communication.

Alternatively, it is divided into sub-blocks based on the cell unit or module width unit that constitutes the one-dimensional code.
(Processing order determination unit 80B)

The machining order determination unit 80B completes the entry into the machining area WA when the machining surface of the work WK is moved into the machining area WA for the plurality of subblocks divided by the subblock division section 80A. The machining order is determined so that the subblocks are machined in order. Note that "completion of entry into the machining area" means, for example, the part of the frame (whether or not the user can see it) that constitutes the subblock, the part farthest from the direction in which the work moves (in a line). It can also be said that when (whether there is a point or not) enters the processing area. More specifically, for example, when the frame constituting the subblock is a square frame and has two sides substantially orthogonal to the direction in which the work moves, the side away from the direction in which the work moves is the machining area. It can also be said that when you enter.
(Expansion information generation unit 80C)

Further, when the operation parameter is adjusted by the operation parameter adjustment unit 80Z described later, the expansion information generation unit 80C reflects the changed operation parameter in the expansion information.
(Trajectory data generation unit 80X)

The locus data generation unit 80X uses the line segment data calculator LC and the printed line segment calculator TC to generate laser emission locus data based on the laser output timing from the laser light detection unit 70 and the angle signal from the scanning angle detection unit 72. Generate.

More specifically, as shown in FIG. 10, the locus data generation unit 80X has an angle signal output from the X scanner 14a and the Y scanner 14b, and a position command for driving the Z scanner 14c in the case of three-dimensional processing. The line segment data calculator LC performs the configuration calculation from the signal to the XY plane segment data. Then, the laser ON / OFF signal is generated by synchronizing the laser output command pulse with the laser output timing signal detected by the laser light detection unit 70 via the phase adjuster PR.

Here, FIG. 11 shows the relationship between the galvano scanner operation in the laser light scanning unit 9 and the printed line segment. As shown in this figure, the calculated XY line segment data includes a printed line segment on which the laser beam LB is output, and a run-up or connecting line on which the laser beam LB is not output. By taking the logical product of the XY line segment data and the laser ON / OFF signal with the printed line segment computer TC, the laser emission trajectory data corresponding to the virtual processing result (details will be described later) is generated. It should be noted that the above-mentioned configuration calculation can be processed in real time by performing it with a DSP, FPGA, or the like. Further, when real-time performance is not required, for example, through an operator, it is possible to pass data to a PC and perform calculation on the application.

Further, the locus data generation unit 80X calculates the printing time required to complete printing the printing pattern.
(Trajectory display control unit 80Y)

The locus display control unit 80Y converts the first locus FT generated by the development information generation unit 80C and the laser emission locus data generated by the locus data generation unit 80X based on the machining pattern set by the machining condition setting unit 3C. The display control is performed so that the second locus ST generated based on the above is displayed on the display unit 82. The second locus ST is a locus that is assumed to be followed by the laser beam during actual laser processing.
(Virtual processing function)

In this way, the locus display control unit 80Y displays the second locus on the display unit based on the locus data generated by the locus data generation unit 80X, so that the user can display the second locus ST followed by the laser beam. 82 You can check from above. As a result, it is not necessary to actually process the object to be processed and then evaluate it based on the obtained processing result. In other words, the image of the machining result obtained by performing virtual machining can be confirmed on the display unit, so the operation parameter setting work that was required in the past, test printing, and the operation parameter can be referred to again with reference to the print result. It is possible for the user to more easily adjust the processing pattern of laser processing while checking the virtual processing result on the screen without performing trial and error of adjusting and performing test printing, which greatly saves labor. It is possible to reduce the cost and tact time without wasting print samples.

FIG. 12 shows how to show the laser beam trajectory when displaying the first trajectory FT and the second trajectory ST on the display unit 82. When the product of the period of the Q-switch 19 and the printing speed is larger than the laser spot diameter, the dot display is displayed as shown in FIG. 12A, and when the product is smaller than the laser spot diameter, the line display is displayed as shown in FIG. 12B. The dot display and the line display can be switched depending on how the laser spot diameter is taken. The laser spot diameter may be adjusted so that the dot display is performed only when the first locus FT and the second locus ST are enlarged and displayed.

Here, in the laser processing apparatus 100, the concept of a print block is used so that the processing conditions can be changed for each block. For example, there are multiple blocks such as a character string, a two-dimensional code, and a logo, and the printing speed is changed for each block according to the printing pattern. In reality, the processing conditions are changed for each block. There is a need to want to. Therefore, the laser processing apparatus 100 can set the conditions for each block number when it is desired to change the processing conditions by using the concept of the print block.

The concept of the print block will be described with reference to the user interface screen of the laser processing condition setting program shown in FIG. Blocks have types such as character strings, two-dimensional codes, and logos. FIG. 13 is a display example of a GUI in which a character string is arranged at block number 0, a two-dimensional code is arranged at block number 1, and a logo is arranged at block number 2. The laser processing apparatus 100 sets operating parameters such as laser output and scan speed for each block and performs processing.

Further, the locus display control unit 80Y can also be provided with an identification display function for displaying the first locus and the second locus in an identifiable manner on the display unit. As an example of the identification display function, there is a highlighting function that emphasizes one trajectory. Specifically, the difference between the laser emission locus data and the processed line segment data is calculated, and all or part of the second locus ST is highlighted based on the difference. For example, in addition to emphasizing only the difference between the first locus and the second locus, the second locus and the first locus are displayed in different colors and line types (thick line, thin line, solid line, broken line, etc.), and the difference between the two. May be visually grasped. Such identification display may be performed by, for example, the identification display unit 75 incorporated in the locus display control unit 80Y (details will be described later), or an identification display unit may be provided separately from the locus display control unit to emphasize. You can also execute the display function. As highlighting to distinguish and display the difference between the laser emission trajectory data and the processed line segment data, highlight processing, for example, coloring with color, grayscale, gradation, shadow, hatching, and other patterns are applied. A display form that can be distinguished from others, such as display, emphasis such as surrounding with a frame, blinking, and grayout, can be used as appropriate.

Furthermore, the locus display control unit 80Y can set a reference value such as a deviation amount in the machining disorder extraction unit 80W (details will be described later), which is a reference for performing highlight processing, to a desired value. When the change is made, the highlighted portion with the changed reference value is updated on the display unit 82 in real time.
(Difference calculation unit 96)

In this example, the locus display control unit 80Y has a function of calculating the difference between the laser emission locus data and the processed line segment data. However, the present invention is not limited to this aspect, and may be configured to cause another member to perform a difference calculation function for calculating the difference between the locus data indicating the second locus and the processed line segment data defining the first locus. Good. For example, apart from the locus display control unit, a difference calculation unit 96 that performs a difference calculation between the second locus and the first locus may be provided.
(Identification display unit 75)

In the example of FIG. 9, the locus display control unit 80Y includes an identification display unit 75 that performs highlighting. Further, various highlighting methods that can be performed by the identification display unit 75 can be mentioned. Further, the user may be able to select from a plurality of highlighting methods.

Of these, (1) to (4) are emphasized by highlighting, and (5) is emphasized by enlarging the selected portion. Further, in (6), the first locus FT and the second locus ST are displayed in parallel, and in (7), the first locus FT and the second locus ST are superimposed and displayed. Further, in (8), the first locus FT and the second locus ST are switched and displayed.

(1) As shown in FIG. 14A, the difference between the second locus ST and the first locus FT is highlighted. In this figure, the vertical lines of "K" and "D" and the vertical line at the left end of the two-dimensional code are highlighted in red, for example, so that it can be understood that this is a printing disorder portion. ..

(2) As shown in FIG. 14B, the entire second locus ST is highlighted for each machining block. In this figure, each of the "Keyence" block and the "Digital Scanning" block is surrounded by, for example, a red dashed line, so that it can be grasped that they are highlighted processing blocks.

(3) As shown in FIG. 14C, a part of the second locus ST is highlighted for each machining block. In this figure, the character part of "K" in "Keyence" and the character part of "D" in "Digital Scanning" are surrounded by, for example, a red dashed line, and they are a part of the highlighted processing block. You can understand that there is something. When highlighting a part of the second locus ST, each subblock divided by the subblock division unit 80A is highlighted.

(4) For the second locus ST, the difference from the first locus FT is highlighted in character units. By combining the above-mentioned (1) and (3), the print disordered portion is specifically specified, and the subblock of the print disordered portion is also highlighted.

(5) As shown in FIG. 15, the entire machining block selected by the machining block selection unit 76 (details will be described later) or the highlighted portion of the selected machining block is enlarged and displayed. FIG. 15A shows the second locus ST in which the difference from the first locus FT before the enlarged display is highlighted, and FIG. 15B shows the portion selected from the highlight display (see FIG. 15A) enlarged. Indicates that it is displayed. The locus display control unit 80Y may automatically detect the print disordered portion and automatically enlarge the display.

(6) As shown in FIGS. 16A and 16B, the first locus FT generated based on the processed line segment data and the second locus ST generated based on the laser emission locus data are simultaneously arranged in separate windows. It is displayed on the display unit 82.

(8) The first locus FT generated based on the processed line segment data and the second locus ST generated based on the laser emission locus data are switched and displayed on the display unit 82.

It should be noted that such an identification display function or a highlight display function may have a similar identification display function or the like not only in the locus display control unit but also in other members. For example, the same identification display function is executed for the machining disordered portion displayed by the machining disorder display control unit 92 according to the second machining disordered portion extracted by the machining disorder extraction unit 80W, which will be described later. The processing disordered portion and the first locus can be displayed on the display unit in a manner that is easy for the user to visually identify.

Further, the print time calculated by the locus data generation unit 80X and required to complete printing the print pattern can be displayed on the display unit 82.

Furthermore, the locus display control unit 80Y has a first mode in which the operation parameters are adjusted with an emphasis on print quality and a second mode in which the operation parameters are adjusted with an emphasis on the print speed (or print time, tact). It is selectively displayed on the display unit 82.

FIG. 17A is a display example of the GUI when the quality-oriented first mode is selected. In the first mode, the operation parameters are adjusted by the operation parameter adjustment unit 80Z so that the quality is optimized for each print block, and the adjusted second locus ST is displayed on the display unit 82. Therefore, the user can automatically obtain the optimized print pattern and setting by selecting the first mode.

FIG. 17B is a display example of the GUI when the tact-oriented second mode is selected. In FIG. 17A, the part of the arrow means that the selected part is selected, and in the second mode, the selected part is the locus data generation unit of the second locus ST generated by changing the operation parameter by the operation parameter adjusting unit 80Z. It is displayed on the display unit 82 in chronological order together with the printing time calculated by 80X. The portion of the arrow in FIG. 17B means that the arrow has been selected, and the user can determine the operation parameter by selecting the desired second locus ST for each print block in the second mode. That is, by selecting the second mode, the user can selectively obtain a desired print pattern and setting from the virtual print result and the print time.
(Scanning control unit 80D)

The scanning control unit 80D controls the laser light generation unit 6, the laser light scanning unit 9, and the shutter unit 71 based on the development information generated by the development information generation unit 80C.

The scanning control unit 80D can switch to a virtual machining mode for performing virtual machining in addition to the normal operation mode during operation.

In the virtual processing mode, the scanning control unit 80D closes the shutter of the shutter unit 71 so that the work WK is not irradiated by the laser light LB, and generates the laser light so that the locus data generation unit 80X obtains the laser emission locus data. The unit 6 and the laser light scanning unit 9 are controlled.

The adjustment information made based on the first locus FT and the second locus ST is reflected in the development information by being updated by the development information generation unit 80C. In the normal operation mode, the scanning control unit 80D opens the shutter of the shutter unit 71 so that the work WK is irradiated by the laser light LB, and the laser light is based on the development information generated by the development information generation unit 80C. The generating unit 6 and the laser light scanning unit 9 are controlled.
(Memory unit 5A)

The storage unit 5A is a member for holding various settings. A storage element such as a semiconductor memory or a hard disk, or a storage medium can be used as such a storage member. For example, the laser processing setting condition set by the processing condition setting unit 3C is held. In addition, the expansion information generated by the expansion information generation unit 80C is stored.

Preferably, the development information generation unit 80C generates the development information in advance before the operation of the laser processing apparatus, and stores the development information in the storage unit 5A. Then, at the time of operation, by reading the expansion information from the storage unit 5A, it is not necessary for the expansion information unit to generate the expansion information one by one, and the processing load can be reduced and the speed can be increased.

More preferably, the expansion information generated by the expansion information generation unit 80C is stored in the storage unit 5A at the time of virtual processing performed before the actual operation. The scanning control unit 80D can switch to a virtual machining mode for performing virtual machining in addition to the normal operation mode during operation. Then, when various processing conditions for laser processing are determined in the virtual processing mode, the development information generation unit 80C generates development information according to the processing conditions obtained at this time, and stores this in the storage unit 5A. deep.
(Operating parameter adjustment unit 80Z)

The operation parameter adjusting unit 80Z adjusts the operation parameters that define the operation of the laser light scanning unit 9 so that the laser emission locus data corresponding to the print disorder portion approaches the print line segment data corresponding to the print disorder portion. The operation parameters adjusted by the operation parameter adjustment unit 80Z are reflected in the expansion information in the expansion information generation unit 80C.

As described above, the user can select the quality-oriented first mode and the tact-oriented second mode in the GUI. The operation parameter adjustment unit 80Z adjusts the operation parameter according to the mode selection.

When the first mode is selected, the operation parameter adjustment unit 80Z adjusts the operation parameters for each print block so that the quality is optimized. The operation parameter adjusting unit 80Z determines the printing conditions for which the printing pattern is optimized based on the analysis results of the machining disorder extraction unit 80W (details will be described later) and the locus data analysis unit 80V (details will be described later).

When the second mode is selected, the operation parameter adjusting unit 80Z emphasizes tact on the print block selected in the first mode based on the analysis results by the processing disorder extraction unit 80W and the trajectory data analysis unit 80V. The value of the operation parameter is changed between the operation parameter of and the operation parameter of emphasis on quality. The operating parameters can be selected and their values to be changed, for example, based on an adjustment parameter set that defines how to change according to the analysis result. The step size and range of the change of the operation parameter in the adjustment parameter set are predetermined for each type of the operation parameter, and preferably, the user can set the step width and the range including the selection of the operation parameter.

On the user interface screen, for example, the operation parameter adjusting unit 80Z places (1) quality first, (2) quality, (3) machining speed, (4) machining speed, and (5) no correction. When the user selects various parameter candidates, the adjustment parameter set corresponding to each parameter candidate is appropriately read out from the storage unit 5A saved in advance, and applied to the selected processing disordered portion or the operation parameter of the print block including the selected processing disordered portion. To do.
(Operation parameter input unit 3Z)

The operation parameter input unit 3Z is for inputting information for operating the laser light scanning unit 9 so that the laser emission locus data corresponding to the print disordered portion approaches the print line segment data corresponding to the print disordered portion. It is a member. For example, the user directly inputs numerical values of operating parameters such as the approach length, waiting time (waiting time), degeneracy ON / OFF, and laser power of the laser light scanning unit 9 via the input unit 3. As shown in Table 1, adjusting the run-up length affects the dot spacing, adjusting the waiting time affects at least one of the splashes or hangers, and adjusting the degeneracy ON / OFF causes arc degeneracy or up / down / left / right. Affects at least one of the symmetries of. Further, when the line speed is variable, the position of the work WK can be grasped on the laser processing apparatus side by a trigger input using an encoder or the like.

The operation parameter input unit 3Z not only inputs initial values of operation parameters that define the operation of the laser light scanning unit 9, but also functions as a member for adjusting the once input operation parameters (details will be described later).

Further, in the example of FIG. 9, the laser processing condition setting device 180 is configured by dedicated hardware, but these members can also be executed by software. In particular, as shown in FIG. 8, a laser processing condition setting program can be installed in a general-purpose computer to function as the laser processing condition setting device 180. Further, in the example of FIG. 9, the laser processing condition setting device 180 and the laser processing device 100 are separate devices, but these can also be integrated integrally. For example, it is possible to add a laser processing condition setting function to the laser processing apparatus itself.

Further, in the example of FIG. 8, the head unit 1 and the controller unit 2 are separated and both are connected by a communication cable, but the present invention is a laser processing apparatus in which the head unit and the controller unit are integrally configured. It can also be applied.
(Threshold input unit 3Za)

The threshold value input unit 3Z inputs a threshold value so that the difference between the laser emission trajectory data generated by the trajectory data generation unit 80X and the processed line segment data generated by the development information generation unit 80C is equal to or less than a predetermined threshold value. It is a member of.

Depending on this threshold value, the judgment as to whether or not the portion corresponds to the processing disorder changes. More specifically, in the processing disorder extraction unit 80W, which will be described later, when the difference from the first trajectory FT among the second trajectory ST displayed on the display unit 82 exceeds a predetermined threshold value, it is extracted as a processing disorder location. To do.

The extraction standard setting unit 3X is a member for setting an extraction standard as a reference for extracting a portion corresponding to the machining disorder as the first machining disorder portion from the second locus displayed on the display unit.
(Processing disorder designation part 3Y)

The machining disorder designation unit 3Y is a member for designating a portion corresponding to the machining disturbance among the second locus ST displayed on the display unit 82 as the machining disturbance portion based on the operation of the user. A deviation map, an acceleration map, and a character string center of gravity auxiliary line CAL that can visually identify the machining disturbance are generated by the machining disturbance extraction unit 80W as needed, and these are displayed in the locus display control unit 80Y. It is controlled to be displayed on 82. Therefore, the user can specify the processing disordered portion of the second locus ST displayed on the display unit 82 based on his / her own judgment or the judgment of the processing disorder extraction unit 80W. ..
(Trajectory data analysis unit 80V)

The locus data analysis unit 80V mechanically identifies the machining turbulence portion in the machining turbulence extraction unit 80W by using the laser emission locus data and the machining line segment data corresponding to the machining turbulence location designated by the machining turbulence designation unit 3Y. For example, by the start point acceleration measurement function of the machining line segment, the start point deviation measurement function of the machining line segment, the arc detection comparison function, the start point acceleration and follow-up error detection function of the reciprocating line segment, and the machining position deviation detection function of the machining block. , The processing disorder of the second locus ST is analyzed, and the type of processing disorder at the processing disorder portion is analyzed. Further, the locus data analysis unit 80V calculates a plurality of different operation parameters for bringing the laser emission locus data corresponding to the machining disordered portion closer to the machining line segment data corresponding to the machining disordered portion.
(Induction display control unit 80U)

The guidance display control unit 80U controls the guidance display on the display unit 82 so that the laser emission trajectory data is closer to the processed line segment data based on the analysis result of the trajectory data analysis unit 80V. Further, the guidance display control unit 80U controls the display unit 82 to display the type of processing disorder according to the analysis result by the trajectory data analysis unit 80V. Preferably, the processing disorder displayed on the display unit 82 is controlled to be sorted according to the type and displayed in a list. For example, the locus data analysis unit 80V calculates the distance between the dots processed by the laser beam LB from the difference between the laser emission locus data and the processed line segment data at the end of the second locus ST, and the calculated dots. When the distance exceeds a predetermined threshold value set in advance and the error type is specified as "Tsuru", the guidance display control unit 80U controls the display of "Tsuru" as the error type.
(Laser processing condition setting program)

Next, as a method of setting the laser processing data as described above, FIG. 18 shows a procedure of generating a processing pattern based on the character information and the like input from the processing condition setting unit 3C by using the laser processing condition setting program. A description will be given based on the user interface screen of FIG. 24. Needless to say, in the examples of the user interface screens of these programs, the arrangement, shape, display method, size, color scheme, pattern, etc. of each input field and each button can be changed as appropriate. By changing the design, the display can be made easier to see, evaluate and judge, and the layout can be made easier to operate. For example, the detailed setting screen can be displayed in a separate window, multiple screens can be displayed in the same display screen, and the like can be changed as appropriate. Further, on the user interface screens of these programs, ON / OFF operations for virtually provided buttons and input fields, numerical values, command input, and the like are specified by the machining condition setting unit 3C. Here, the processing conditions are set by the input device connected to the computer in which the program is incorporated. In the present specification, "pressing" includes not only physically touching and operating the buttons, but also clicking or selecting by the input unit and pressing the buttons in a pseudo manner. The input / output devices constituting the input unit and the like are connected to the computer by wire or wirelessly, or are fixed to the computer or the like. Examples of general input units include various pointing devices such as a mouse, keyboard, slide pad, track point, tablet, joystick, console, jog dial, digitizer, light pen, ten key, touch pad, and AccuPoint. Further, these input / output devices can be used not only for program operations but also for hardware operations such as laser processing devices. Further, by using a touch screen or a touch panel on the display itself of the display unit 82 that displays the interface screen, the user can directly touch the screen to perform input and operation, or voice input or other existing existing ones. Input means can be used, or these can be used in combination.

This laser processing condition setting program can edit three-dimensional laser processing data. However, considering users who are not good at editing 3D data, we have prepared a "2D editing mode" that can only be set on a plane and cannot be edited on 3D, so that 3D laser processing data can be processed. It may be possible to switch to a possible "3D editing mode". When a plurality of such editing modes are provided, an editing mode display field 270 indicating the current editing mode and an editing mode switching button 272 for switching the editing mode are provided. In the example of FIG. 18, when the laser processing condition setting program is started, "2D editing mode" is set, and the editing mode display field 270 provided at the upper right of the screen indicates that the current editing mode is "2D editing". I'm letting you. By setting the 2D editing mode, which is relatively easy to operate, as the default editing mode at startup, even a user who is not good at editing 3D laser processing data can operate it without any confusion. In addition, the edit mode at startup can be configured to be changeable by the user, and can be set so that a user who is proficient in operation can edit the three-dimensional laser processing data without switching the edit mode. Needless to say, it is also possible to set only two-dimensional laser processing data for a laser processing apparatus capable of two-dimensional laser processing.

18 to 24 show an example of the user interface screen of the laser processing condition setting program, the edit display field 202 displaying the image of the processing pattern printed on the work WK on the left side of the screen, and the specific on the right side. A print pattern input field 204 for designating various data as various processing conditions is provided. In the print pattern input field 204, the "basic setting" tab 204h, the "shape setting" tab 204i, and the "detailed setting" tab 204j can be switched as tabs for selecting setting items. In the example of FIG. 8, the "basic setting" tab 204h is selected, and a processing type designation field 204a, a character data designation field 204d, a character input field 204b, and a detailed setting field 204c are provided here. The processing type designation field 204a specifies, as the type of processing pattern, whether to perform operation as a processing machine or a printing pattern including images such as character strings, symbols, logos, patterns, and figures. In the example of FIG. 18, a character string, a logo, a figure, and a processing machine operation are selected from the processing type designation field 204a with a radio button. Further, the character data designation field 204d specifies the type of character data. Here, one of a character, a bar code, a two-dimensional code, and a GS1 data bar / CC (Composite Code) is selected from the pull-down menu. Further, a more detailed type is selected in the type designation field 204q according to the type of the selected character data. For example, if you select a character, the font type, if you select a barcode, the barcode type such as CODE39, ITF, 2 of 5, NW7, JAN, Code 28, etc., if you select a two-dimensional code, the QR code (Registered trademark), micro QR code, two-dimensional code type such as DataMatrix, GS1 DataBar-14, GS1 DataBar-14 CC-A, GS1 DataBar Stacked, GS1 DataBar Stacked CC- Specify the GS1 data bar code type such as A, GS1 DataBar Limited, GS1 DataBar Limited CC-A, or the GS1 data bar composite code type. In the character input field 204b, the character information to be printed is input. The input character is printed as a character string as it is when the character is selected in the character data designation field 204d. On the other hand, when a symbol is specified, a processing pattern in which the input character string is encoded according to the type of the selected symbol is generated. The processing unit 80 generates the processing pattern according to the setting in the processing condition setting unit 3C. Further, the detailed setting field 204c switches tabs and specifies details of printing conditions such as "printing data" tab 204e, "size / position" tab 204f, and "printing condition" tab 204g.

Further, in the edit display field 202, a setting plane in which a part of the print area is displayed in a two-dimensional manner is displayed. Here, the print area displayed in the edit display field 202 can be enlarged or reduced, and when the print area is enlarged and displayed, a part of the setting plane corresponding to the print area is displayed in the edit display field 202. Will be done. It is also possible to reduce the print area in the edit display field 202 to display the entire print area, that is, the maximum print area. In this way, at least a part of the setting plane corresponding to the maximum machining area can be displayed in the edit display field 202. Further, the print area can be displayed in the edit display field 202 in three dimensions. The user can set a processing block (a print block because printing is possible in this example) on the setting plane displayed in the edit display field 202. The display example in the edit display field 202 displayed on the display unit corresponds to the print area 1: 1.

In the example of FIG. 19, the GS1 data bar / CC is specified in the character data designation field 204d, and the GS1 DataBar Limited CC-A is specified in the type designation field 204q. On the "Print Data" tab 204e, specify the module width, module fine adjustment, print line width, linear code height, separator height, 2D module height, and the like numerically. In addition, mode automatic, black-and-white inversion, password, etc. can be specified as needed.

If you select the machining machine operation from the machining type specification field 204a, the machining type can be selected from the pull-down menu, such as fixed point, straight line, broken line, counterclockwise circle / ellipse, clockwise circle / ellipse, trigger ON middle fixed point, etc. Can be selected. In the operation of the processing machine, a line segment coordinate specification field is provided as a processing pattern instead of the character input field, and a locus such as a straight line or an arc is specified by coordinates.
(Machining block setting means)

As described above, the print pattern information related to one processing block, that is, the print block is set. It is also possible to set a plurality of print blocks. That is, it is possible to set a plurality of print blocks in the processing area and perform printing processing under different printing conditions. A plurality of print blocks may be set for one work or a machined (printed) surface, or may be set for each of a plurality of works existing in the machined area.

The print block is set by the machining block setting means. In the example of FIG. 18, as one form of the processing block setting means, a block number selection field is provided in the upper field of the print pattern input field 204. The block number selection field is provided with a number display field 205a for displaying the block number, and as a number designation means, a ">" button, a ">>" button, a "<" button, and a "<<" button. When the ">" button is pressed, the block number is incremented by 1 and a new print block can be set. Also, when changing the setting of the set print block, the block number can be selected by operating the ">" button in the same manner, and the setting of the corresponding print block can be recalled. If you press the ">>" button, you will jump to the final block number. Further, pressing the "<" button returns one block number, and pressing the "<<" button jumps to the first block number. Further, the block number can be specified by directly inputting a numerical value in the numerical display field of the block number selection field. In this way, the print block is selected in the block number selection field, and the print pattern information is specified for each print block. In this example, the block number can be set from 0 to 255.

In FIG. 19, the GS1 data bar is set as the print block of the block number 000. Here, when the GS1 data bar is selected in the character data specification field 204d and the character string to be encoded is input in the character input field 204b, a symbol corresponding to the input character string is created, and the image is displayed in the edit display field 202. Is displayed. Further, if the symbol setting condition is changed in the print pattern input field 204, the display image of the symbol displayed in the edit display field 202 also changes accordingly.

Further, if necessary, a "human" button, a "separator" button, an "update character insertion" button, and the like can be provided. In the example of FIG. 18, a floating bar provided with various functions is arranged at the bottom of the character input field 204b, and if one of them, the "human" button 204r, is clicked, the set print block can be displayed. The HR character string corresponding to the symbol can be acquired. The details will be described later. In addition, the "separator" button is used to input a plurality of types of barcode delimiters when setting a composite code. The "Insert update character" button is used to enter update characters such as serial number and date and time information.

As shown in FIG. 19, the corresponding HR character string is set in the state where the symbol input is completed. In this example, the HR character string corresponding to the GS1 data bar is set as a print block different from the GS1 data bar. First, as shown in FIG. 20, the block number is switched from 000 to 001 in the block number selection field, and a new print block is set. Here, if the ">" button is pressed by the number designation means or the numerical value is directly input in the number display field 205a to switch the display of the block number in the number display field 205a from "000" to "001", a new value is obtained. The print block can be set. Here, a character string is selected with a radio button in the processing type designation field 204a. Then, when the "human" button 204r is pressed, the HR character setting screen 210 of FIG. 21 is displayed. The HR character string is set from the HR character setting screen 210. Here, the HR character string can be input by referring to the corresponding symbol.

In the example of FIG. 21, the HR character string can be automatically acquired by designating the block number of the print block in which the GS1 data bar corresponding to the HR character string is set. Specifically, when "0" is specified in the "reference block number" field 213 provided in the middle of the HR character setting screen 210, the HR character string corresponding to the GS1 data bar set in the reference block number "0" is specified. Is displayed in the "print sample" column 211. Further, the corresponding HR character string reference character string is displayed in the "character string" column 212 below it. Here, "% H <0001>" is input as the HR character string reference character string. "%" Represents a special character and "H" represents a human readable character string. Further, <0001> means to refer to the 0th one-dimensional code of the block. For example, <0052> indicates that the second-dimensional code of the fifth block is referred to.

Further, the "reference symbol" column 214 in the "GS1 DataBar & CC option" setting column of the HR character setting screen 210 specifies a reference symbol of the composite code. Here, a "linear code" is specified.

In this way, the machining condition setting unit 3C refers to the print block in which the one-dimensional code or the two-dimensional code is set, acquires the human readable character string corresponding to the one-dimensional code or the two-dimensional code, and obtains the human readable character string. A readable character string can be set as a print block of the character string. With this method, it is possible to save labor and avoid input errors. In the above example, the printing block is set for each block by using the machining condition setting unit 3C. However, various methods can be considered as the setting method by the machining condition setting unit 3C. For example, the user can use the GUI. When a series of numbers are input in, the corresponding one-dimensional code, two-dimensional code, and human readable character string may be automatically set.

When the "Add" button 215 is pressed in the state where the HR character string is displayed in the "print sample" field 211 in this way, the acquired HR character string reference character string (for example, "" is displayed in the character input field in FIG. 20. % H <0001> ") is displayed. Further, a print sample of the HR character string is displayed in the edit display field 202 according to the conditions set in the print pattern input field 204 (FIG. 22). Here, as with the symbols described above, if the setting condition of the HR character string is changed in the print pattern input field 204, the display image of the HR character string displayed in the edit display field 202 also changes accordingly. Further, the print position and the size (scale) of the entire character string can be changed by dragging the image of the symbol or HR character string displayed in the edit display field 202 using a pointing device such as a mouse. As a result, as shown in FIG. 22, an HR character string having an appropriate size can be arranged and printed under the symbol.

Next, the print pattern of the HR character string of the two-dimensional bar code constituting the composite code is set to the print block of the block number "002". When "002" is set for the block number and the "human" button 204r is clicked again, the HR character setting screen 210 for setting the HR character string appears as shown in FIG. 23. Here, the "reference block number" field 213 is set to 0, and the two-dimensional code is selected from the pull-down menu 68 in the "reference symbol" field 214. As a result, the HR character string corresponding to the two-dimensional code constituting the composite code set to the block number "000" is displayed in the "print sample" column 212.

When the "Add" button 215 is pressed in this state, the acquired HR character string is displayed in the character input field 204b as shown in FIG. 24. Further, an image of the GS1 data bar to which the HR character string is added according to the type, type, line type, size / position, and printing condition of the character data set in the print pattern input field 204 for setting the type of print data and the like. Is displayed in the edit display field 202.

As for the image of the HR character string displayed in the edit display field 202, the print position and the size (scale) of the entire character string can be changed by a drag operation using a pointing device such as a mouse in the same manner as described above. In this way, the corresponding HR character string is arranged in an appropriate size under the one-dimensional bar code constituting the composite code, and the corresponding HR character string is also placed on the two-dimensional bar code in an appropriate size. Can be placed in the bar.
(Adjustment of machining disorder mode and operation parameters)

The laser processing apparatus generally includes a galvano mirror that can scan in two directions of the X-axis and the Y-axis, and by operating the galvano mirror, an arbitrary print pattern can be printed on the work WK. .. However, this galvanometer mirror has a response delay due to the influence of inertia, and machining disturbance occurs due to this response delay. Among the processing disturbances, there are three main modes as shown in FIG. 25A: (1) hanging, splashing, (2) uneven dot spacing, and (3) arc degeneracy.
(1) Being hung up

Among the types of processing disturbance shown in FIG. 25A, (1) is "hanging". In the laser processing apparatus, when the locus of the laser beam LB is scanned so as to draw an angle, it is scanned so as to draw an arc inward as shown in the central figure of FIG. 25B due to the influence of inertia. Since this phenomenon also occurs in the run-up and the scanning of the connection (see FIG. 11) where the laser beam LB is not output, the laser beam LB is emitted without following the galvanometer mirror to the actual starting point. Is formed. Also, if the run-up at the end of the print line is short, the run-up is short, so the laser has not yet turned off when the galvanometer mirror is trying to move to the next point without reaching the original end point. Therefore, "splash" occurs.

In order to eliminate the "hanging", a waiting time for waiting for scanning of the laser beam LB is provided among the operating parameters. In addition, in order to eliminate the "splash", the approach length is extended among the operation parameters. As shown in FIG. 11, by providing a waiting time, the galvano mirror follows the waiting point, and from there, the run-up is inserted for the first time and the printed line is controlled to be printed in a straight line without causing "hanging". Can be printed on. By increasing the waiting time, a clearer straight line can be printed.
(2) Uneven dot spacing

Among the types of processing disturbance shown in FIG. 25A, the unevenness of the dot spacing in (2) will be described. The galvanometer mirror scan accelerates until it reaches a certain speed and slows down until it stops after reaching a certain speed. When the laser beam LB is emitted during the transitional period of this speed, uneven dot spacing occurs. At the location where the dot spacing is uneven, the length of the processed line segment changes and the appearance of the dots becomes dirty. Further, if the dot spacing is tight, the work WK may be burnt or the resin work WK may be melted.

In order to eliminate this uneven dot spacing, the approach length is lengthened among the operating parameters. When the approach length is lengthened, the laser beam LB is emitted after the galvano mirror scan reaches a certain speed, so that the dot spacing becomes uniform.
(3) Arc degeneracy

Among the types of machining disturbance shown in FIG. 25A, (3) is "arc degeneracy". In the laser processing apparatus, when scanning so that the locus of the laser beam LB draws an angle as shown in the left figure of FIG. 25B, due to the influence of inertia, an arc is formed inward as shown in the central figure of FIG. 25B. It is printed as if drawing.

To solve the problem that such corners cannot be formed, as shown in the right figure of FIG. 25B, the corners are printed by scanning the galvano mirror with a run-up added to the printed line. Can be done.

Further, when scanning so that the locus of the laser beam LB draws an arc as shown in the left figure of FIG. 25C, similarly, as shown in the central figure of FIG. 25C, it is printed inside the command arc. It ends up.

To solve the problem that the arc is degenerated inward, the influence of the response delay can be reduced by slowing down the operating speed of the galvanometer mirror at the time of printing. However, regarding the arc degeneracy of FIG. 25C, there is a problem that when the curvature of the print pattern becomes large, the print disorder occurs regardless of the operating speed.
(Processing disorder extraction unit 80W)

The machining disorder extraction unit 80W extracts the portion corresponding to the machining disturbance in the second locus ST displayed on the display unit 82 as the machining disturbance portion. As an extraction method, as shown in FIG. 26, for example, a deviation map, an acceleration map, and a character string center of gravity auxiliary line for visually identifying a processing disordered portion can be mentioned. In addition, as another extraction method, for mechanically identifying a machining disordered portion, for example, a machining line segment start point acceleration measurement function, a machining line segment start point deviation measurement function, an arc detection comparison function, and a reciprocating line segment start point. Examples include an acceleration and tracking error detection function and a machining position deviation detection function of the machining block.
(Deviation map)

The deviation map is a logic of deviation signal values of the XY-axis scanners 14a and 14b obtained by the scanning angle detection unit 72 of the laser light scanning unit 9 and a laser ON / OFF signal obtained by the laser light detection unit 70. The product is expanded on the XY plane. The locus display control unit 80Y color-codes the locus display unit 82 according to the amount of deviation and superimposes it on the second locus ST, which is a virtual machining result, so that the first locus display is visually a reference in the machining area. The location where the positional error between the locus FT and the second locus ST is large can be grasped, and the operation parameters can be adjusted by the input unit 3.

FIG. 27 is a display example of the deviation map, and the colors are shown by hatching in this figure. In this display example, a portion having a deviation amount of 20% or more is shown in red, a portion having a deviation amount of 10% or more and less than 20% is shown in yellow, and a portion having a deviation amount of less than 10% is shown in green.

Further, FIG. 28 is another display example of the deviation map. In this figure, out of the large squares formed by arranging square blocks in 8x8, each of the three thick line blocks located at the four corners is displayed on the GUI as, for example, a red box. Three broken lines located on the center side are displayed on the GUI as, for example, a thick yellow line. For example, a block displayed in a red frame is a print block with a large deviation amount, and a block displayed in a yellow frame is a print block with an intermediate deviation amount. In minutes, print data and virtual print results can be displayed in an easy-to-understand manner using colors, symbols, numbers, and the like.
(Acceleration map)

The acceleration map generates an acceleration signal by second-order differentiation of the position signals of the XY-axis scanners 14a and 14b obtained by the scanning angle detection unit 72 of the laser light scanning unit 9, and the generated acceleration signal and the laser. The logical product of the laser ON / OFF signal obtained by the photodetector 70 is developed on the XY planes. The locus display control unit 80Y color-codes the display unit 82 according to the magnitude of acceleration and superimposes it on the second locus ST to visually grasp the portion where acceleration / deceleration is large in the machining area. , The operation parameter can be adjusted by the input unit 3.

29A is an example of a line display of an acceleration map, FIG. 29B is an example of a dot display obtained by enlarging the acceleration map, and FIG. 29C is a diagram showing the relationship between the dots shown in FIG. 29B and the acceleration. Is. As shown in FIGS. 29B and 29C, the laser dot spacing is not constant at the location where the acceleration changes. For this reason, a portion where acceleration / deceleration is large can be extracted as a portion with irregular processing because the length of the processing line segment changes and the appearance of dots becomes dirty.

As shown in FIG. 29C, an upper limit reference value is provided, and a portion exceeding the upper limit reference value is displayed in different colors. Further, preferably, a lower limit reference value is provided, and a portion below the lower limit reference value is displayed in different colors. In this way, the processing disordered portion can be visually extracted, and the operation parameter can be adjusted by the input unit 3.
(Character string center of gravity auxiliary line CAL)

The character string center of gravity auxiliary line CAL is an auxiliary line obtained by connecting the centers of gravity of characters and symbols obtained from the virtual processing result. As a result, the processed quality can be displayed in an easy-to-understand manner. When processing a print pattern such as a character or symbol string, if the processing speed is high or the size of the print pattern is small, the position error of the components of the print pattern is large due to various factors (for example, arc degeneracy). Become.

FIG. 30A is a display example of the first locus FT which is a reference, and FIG. 30B shows the character string center of gravity auxiliary line CAL and the bottom alignment in the second locus ST corresponding to the first locus FT which is a virtual processing result. This is a display example of the auxiliary line UAL. In this way, by displaying the character string center of gravity auxiliary line CAL and / or the bottom alignment auxiliary line UAL, it is possible to grasp the part where the position error of the component is large, and the input unit 3 determines the processing speed, waiting time, etc. The operating parameters can be adjusted.
(Start point acceleration measurement function for machining line segment)

The machining line segment start point acceleration measurement function is a function for generating acceleration data of the machining line segment at the machining start point of each line segment and making it possible to grasp the machining position error. At the line segment machining start point, the machining line segment length is more likely to change than the reference data due to acceleration and deceleration.

Therefore, in the measurement with this function, the position signals of the XY-axis scanners 14a and 14b obtained by the scanning angle detection unit 72 of the laser light scanning unit 9 at the processing start point of the line segment are second-order differentiated and processed. The acceleration data of the line segment is generated, the logical product of this acceleration data and the laser ON / OFF signal is taken, and the acceleration data in the machining region is obtained. Where the acceleration is large in the machining region, the machining line segment length is different, so that the machining position error is large and the laser dot spacing is not constant.

FIG. 31 is an explanatory diagram of the start point acceleration measurement function of the processing line segment. In this figure, the processed line segments are printed in numerical order in the direction of the arrow starting from the numbered portion. Acceleration data is generated at the numbered part corresponding to the processing start point of the line segment. As a result, the amount of acceleration at each start point position can be known, so that the machining position error can be grasped.
(Starting point deviation measurement function for processing line segment)

The processing line segment start point deviation measurement function is a function for generating deviation data of the processing line segment at the processing start point of each line segment and making it possible to grasp the processing position characteristics of the response of the galvano scanner. Since the processing start point of the line segment is switched from the connecting line to the run-up, the response delay of the laser light scanning unit 9 occurs, and it is easy to leave a curved processing trace.

Therefore, in the measurement with this function, deviation data is obtained from the position signals and reference data of the XY-axis scanners 14a and 14b obtained by the scanning angle detection unit 72 of the laser light scanning unit 9 at the line segment processing start point. Is calculated. As the deviation data, the deviation signal generated by the scanner drive circuit 52 may be diverted. The logical product of this deviation data and the laser ON / OFF signal is taken to obtain the deviation data in the machining region. A part where the deviation amount at the start point of the line segment is large indicates that erroneous processing is performed due to the response delay of the galvano scanner.

FIG. 32 is an explanatory diagram of the start point deviation measuring function of the processing line segment. In this figure, deviation data is generated at a numbered portion corresponding to a processing start point of a line segment. As a result, the amount of deviation at each start point position can be known, so that the processing position characteristic of the response of the galvano scanner can be grasped.
(Arc detection comparison function)

The arc detection comparison function is a function for detecting an arc-shaped machined portion, comparing the deviation amount or the difference in the arc diameter between the reference data and the virtual machined result, and making it possible to grasp the machined quality of the arc. When machining an arc, the faster the machining speed and the smaller the diameter of the arc, the smaller the arc diameter of the machining result due to the response delay of the laser beam scanning unit 9, and the poorer the machining quality.

Therefore, in the measurement with this function, the arc-shaped machined portion is detected from the reference data, and the reference data and the virtual machining result are compared at the arc-shaped machined portion. The comparison is made from the deviation amount between the position signals and the reference data of the XY-axis scanners 14a and 14b obtained by the scanning angle detection unit 72 of the laser light scanning unit 9, or the arc diameter and the reference data calculated from the position signal. This is done by finding the difference from the calculated arc diameter. A portion having a large difference in the deviation amount or the arc diameter calculated in this way indicates that the processed quality of the arc is poor.

33A is a display example of the first locus, and FIG. 33B is a display example of the second locus, for explaining the arc detection comparison function. The hatched portion in FIG. 33A is the arc-shaped processed portion detected in the first locus FT, and the hatched portion in FIG. 33B is the arc-shaped processed portion of the second locus ST corresponding to the arc-shaped processed portion. Is. From the first locus FT and the second locus ST, the deviation amount or the difference in the arc diameter at the arc-shaped machined portion is calculated. By evaluating this deviation amount or the difference in the arc diameter, the processing quality of the arc can be grasped.
(Starting point acceleration and tracking error detection function for reciprocating line segment)

The start point acceleration and follow-up error detection function of the reciprocating line segment generates the acceleration data of the processed line segment at the processing start point of each line segment in the adjacent line segment, and the acceleration data is less than the specified value during the line segment processing. This is a function for grasping the processing quality and the tracking error by measuring the deviation amount at a certain point and calculating the delay time from the driving speed of the laser beam scanning unit 9.

When processing a plurality of parallel line segments, in order to shorten the processing time, as shown in FIG. 34A, a method of reciprocating the laser light scanning unit 9 for processing is used. Since acceleration / deceleration is repeated by the reciprocating operation of the laser light scanning unit 9, the change in acceleration is large at the starting point, and dot clogging is likely to occur. Further, by processing the line segments in a reciprocating manner, the deviation due to the tracking error of the laser beam scanning unit 9 is doubled between the adjacent processed line segments, so that the positions of the start point and the end point of the adjacent line segments do not match. It is processed irregularly.

Therefore, in the measurement with this function, the position signals of the XY-axis scanners 14a and 14b obtained by the scanning angle detection unit 72 of the laser light scanning unit 9 at the processing start point of the line segment are second-order differentiated and processed. The acceleration data of the line segment is generated, the logical product of this acceleration data and the laser ON / OFF signal is taken, and the acceleration data in the machining region is obtained. Then, the deviation amount is measured at the point where the acceleration data is equal to or less than the specified value during the line segment processing, and the delay time is calculated from the driving speed of the laser light scanning unit 9. In adjacent line segments, the larger the acceleration at the machining start point, the worse the machining quality. Further, by advancing the output timing of the reference by the calculated delay time, the influence of the tracking error shown in FIG. 34B can be suppressed.
(Processing position deviation detection function of processing block)

The processing position deviation detection function of the processing block detects the position of the print block from the virtual processing result and compares it with the reference data to calculate the amount of position error of the print block and grasp the balance of the arrangement of the print block. It is a function to do.

When there is a demand for high-speed machining of the machining element, when the size of the machining element is small and the number of accelerations and decelerations is large, and further, a sufficient waiting time is secured to reduce the response delay of the laser light scanning unit 9. It may not be possible. In these cases, as shown in FIG. 35, the position of the print block is detected from the second locus FT which is the virtual processing result and compared with the first locus FT which is the reference data to reduce the position error amount of the print block. calculate.

For the print block position, the start point or the center of gravity is obtained from the second locus FT, and the difference between this and the first locus FT is obtained. The larger the amount of position error of the print block position, the more unbalanced the print block arrangement is. The print block position of the reference data can be adjusted by the amount of the position error.
(Automatic adjustment of operating parameters)

When the adjustment content of the operation parameter is uniquely obtained based on the second locus ST which is the virtual machining result, the operation parameter adjustment unit 80Z corrects the machining disorder by automatically adjusting the operation parameter. With respect to the machining disturbances illustrated below, the adjustment contents of the operation parameters can be uniquely obtained.
(Clogged dots at the start of processing)

By outputting the laser beam LB before the processing speed stabilizes, "clogging of dots at the processing start portion" occurs. Among the operating parameters, the approach length, approach speed, and laser ON / OFF timing are automatically adjusted so that machining can be started by outputting the laser after detecting the point where the acceleration of the galvano scanner becomes minute. Specifically, the adjustment is performed so that the start point acceleration obtained by the "start point acceleration measurement function of the processing line segment" in the processing disorder extraction unit 80W is equal to or less than a specified value.
(Hanging at the start of processing)

At the start of line segment processing, due to the response delay of the galvano scanner, the tip of the processed line segment becomes curved or key-shaped by outputting the laser beam LB before the galvano scanner shifts to line segment processing. "Tangle of the starting part" occurs. Among the operation parameters, the linearity or deviation amount of the start point of the line segment processing operation is detected, and the laser is output when the processing line segment at the start point is straight or the deviation amount of the start point is less than the reference value. The waiting time, approach length, and laser ON / OFF timing are automatically adjusted. Specifically, the above adjustment is performed so that the start point deviation obtained by the "start point deviation measurement function of the processing line segment" in the processing disorder extraction unit 80W is equal to or less than the specified value.
(Degeneration of arc machined part)

Due to the response delay of the galvano scanner, an "arc machined line segment" in which the arc diameter becomes smaller occurs. The diameter of the arc is calculated from the position signal, and the machining speed among the operation parameters is adjusted so that the difference from the diameter of the first locus FT, which is the reference data, is less than the reference value. Specifically, the adjustment is performed so that the arc diameter difference obtained by the "arc detection comparison function" in the machining disorder extraction unit 80W is equal to or less than the specified value.
(Position shift between start point and end point of reciprocating line segment processing)

In reciprocating line segment processing used in one-dimensional and two-dimensional bar code processing, the start and end points of the processing line segment are not aligned due to the acceleration of the galvano scanner not being in time and the tracking error during processing. "Position of start point and end point of reciprocating line segment processing" occurs. In order to detect that the galvano scanner has a constant velocity, the approach length and the laser ON / OFF timing among the operating parameters are automatically adjusted so that the laser beam LB is output after detecting the point where the acceleration becomes minute.

In order to adjust the influence of the tracking error, the delay time of the position signal with respect to the reference data is measured, and the output timing of the reference data for the measured time is advanced. Specifically, the tracking error obtained by the "starting point acceleration and tracking error detection function of the reciprocating line segment" in the machining disorder extraction unit 80W is reflected in the reference data, and the adjustment is performed so that the starting point acceleration is equal to or less than the specified value.
(Print block processing position shift)

When there is a demand to print the machined element at high speed, or when the size of the machined element is small and the number of accelerations and decelerations is large, it may not be possible to secure a sufficient waiting time to reduce the response delay of the galvano scanner. .. In this case, the position of the print block is detected from the virtual processing result, and the amount of misalignment is calculated by comparing the reference data. By adding the calculated misalignment amount to the reference data, the position of the print block is brought closer to the reference data, and the quality of the processing result is improved. Specifically, the deviation of the block position obtained by the "machining position deviation detection function of the machining block" in the machining disorder extraction unit 80W is reflected in the reference data.
(Semi-automatic adjustment of operating parameters)

When the user puts the mouse cursor on the processing disorder position on the user interface, as shown in FIG. 36, parameter candidates that can adjust them are popped up. When the parameter value is raised or lowered using the mouse cursor, the galvano scanner operates immediately, and with the operating parameter value changed to the specified value, scanning of the processing disordered part is performed, and the scanning result is virtual. It is displayed as a processing result.

In this case, the function of a pointing device such as a mouse wheel may be used instead of the pop-up display of the parameter candidate. For example, there is a method in which parameters are changed according to the rotation direction and the amount of rotation of the mouse wheel, scanning of a machining disordered portion is performed, and the scanning result is displayed. In addition, instead of popping up the parameter candidates, a parameter candidate value in which the parameters related to the machining disorder are changed by a specific value or ratio is generated, and the galvano scanner is operated according to this, and some virtual machining result candidates are generated. There is also a way to get. Candidates for the obtained virtual machining results are displayed in a list, and the user may select the most suitable one. At this time, as an index for selecting the virtual machining result, a function of displaying the machining time can be provided in addition to the candidate image of the virtual machining result displayed on the screen. The user can select the appropriate parameters for the machining target from the trade-off between machining time and machining quality. Further, as an index for selecting the virtual machining result, there is also a method of displaying a numerical value of the machining status or a rank-classified one such as A, B, or C.

Several evaluation functions are used to quantify the virtual machining results. In this case, a position signal, a deviation signal, a laser ON / OFF signal, etc. are input to the evaluation function, and the evaluation result is output. For example, by using the position signal and the laser ON / OFF signal as evaluation inputs and taking the logical product of the second-order differentiated position signal and the laser ON / OFF signal, it is possible to calculate the change in the processing speed during the processing period.

By adjusting the approach length and the machining waiting time so that this evaluation output becomes small, the positional deviation of the machining start portion and the machining dot interval can be made constant. Further, by taking the deviation signal and the laser ON / OFF signal as evaluation inputs and taking the logical product of these two signals, the machining position shift amount in the machining period can be calculated. By adjusting the machining waiting time and the machining speed so that this evaluation output becomes small, the deviation of the machining position and the amount of degeneracy can be adjusted.
(Procedure for adjusting operation parameters by virtual machining)

Next, the procedure for adjusting the operation parameters by virtual machining in the present embodiment will be described with reference to the flowcharts of FIGS. 40, 45, and 46 based on the flowchart of FIG. 37. First, as shown in FIG. 37, in step ST1, the user sets, for example, print characters on the GUI shown in FIG. 38 in the machining condition setting unit 3C. FIG. 38A is an example of a GUI for printing a character string, but the print target may be a logo (graphic), a bar code, or a two-dimensional code as well as the character string. In FIG. 38A, the font of the character string can be changed in the font item, and single line, thick line, wobble, size, and the like can be set. In FIG. 38B, a button for setting the shape of the printed surface is provided as a button for setting the XY plane or the three-dimensional shape. By pressing this button, the user can set the layout of the print surface shape, and in the example of FIG. 38B, the user can set how to arrange the print characters on the XY plane.

In step ST2, the user sets machining conditions such as laser power and scan speed in the machining condition setting unit 3C. When the print condition button at the right end is pressed on the GUI shown in FIG. 38, a GUI in which print conditions can be set as shown in FIG. 39 is displayed. The user sets printing conditions such as laser power and scan speed on this GUI.

In step ST3, the development information generation unit 80C defines the trajectory that the laser light should follow by the laser light scanning unit 9 based on the print pattern and the processing conditions set by the user in the processing condition setting unit 3C. Generates development information including data and control data for controlling the laser beam ON or OFF. Then, the scanning control unit 80D closes the shutter of the shutter unit 71 so that the work WK is not irradiated by the laser light LB, and the laser light generating unit 6 and the laser light scanning are performed so that the locus data generation unit 80X obtains the laser emission locus data. The virtual machining is executed by controlling the part 9. Next, the locus data generation unit 80X uses the line segment data calculator LC and the printed line segment calculator TC to emit a laser locus based on the laser output timing from the laser light detection unit 70 and the angle signal from the scanning angle detection unit 72. Generate data.

In step ST4, the machining disorder extraction unit 80W converts the expansion information generated by the expansion information generation unit 80C based on the processing pattern set by the processing condition setting unit 3C and the laser emission locus data obtained in step ST3. Based on this, the machining disordered portion is extracted, and the identification display unit 75 of the locus display control unit 80Y highlights the machining disordered portion on the display unit 82. As for the processing disordered portion, all the parts exceeding the threshold value input by the threshold value input unit 76 may be highlighted, or the upper few high-order parts having a large difference may be highlighted. As described in the item of the identification display unit 75, the highlighting is not limited to the highlighting, and there are various methods. Therefore, a suitable method may be appropriately adopted.

For example, as shown in FIG. 41A, on the user interface screen, the processing disordered portion is highlighted by adding a sign and a mark to the processing disordered portion of the printed character.

In step ST5, the user determines whether or not it is necessary to correct the processing disordered portion highlighted in step ST4. If correction is necessary, the step of step ST6 is executed. If there is no need for modification, the process proceeds to step ST7, and the machining conditions are determined.

In step ST6, which error type of machining disorder occurs at the machining disorder location selected by the user is analyzed, and the operation parameters are adjusted. This procedure will be described in detail with reference to the flowchart of FIG. As shown in FIG. 40, in step ST61, the user selects a portion to be corrected from the machining disordered portions highlighted in step ST4. The machining disorder designation unit 3Y designates a portion selected by the user as a machining disturbance portion that the user wants to correct.

For example, as shown in FIG. 41A, on the user interface screen, the code attached to the processing disordered part of the printed character and the correction part selection such as "error part 1", "error part 2", and so on. It is associated so as to match the sign attached on the screen, and when the correction part selection button of "error part 1" is pressed, the parameter candidates corresponding to "error part 1" are displayed.

Before pressing the correction part selection button, "do not correct" is set by default, and when a parameter candidate is selected, the processing disorder specification unit 3Y sets the "error part" as the processing disorder part that the user wants to correct. It will be specified.

In step ST62, the locus data analysis unit 80V analyzes which error type of machining disorder occurs at the machining disorder location selected by the user, and identifies an error type that may be suitable as the error type. As described above, for example, the error type is specified as the error type, such as (1) hanging, splash, (2) uneven dot spacing, and (3) arc degeneracy (“mode and operation of machining disorder”). See "Adjusting Parameters" section). The locus data analysis unit 80V calculates, for example, the distance between the dots processed by the laser beam LB from the difference between the laser emission locus data and the processed line segment data at the end of the second locus ST, and the calculated dots. When the distance exceeds a predetermined threshold set in advance, the error type is specified as "hanging".

In step ST63, the guidance display control unit 80U controls the display unit 82 to display the type of machining disturbance according to the analysis result by the trajectory data analysis unit 80V, and the display unit 82 displays the type of machining disturbance. .. In step ST62, when the locus data analysis unit 80V specifies, for example, the error type "Tsuru", the guidance display control unit 80U controls so that the error type is displayed as "Tsuru" on the display unit 82. ..

For example, as shown in FIG. 41A, on the user interface screen, in the column to the right of the items provided as "error location 1", "error location 2", etc., the guidance display control unit 80U The error type is displayed. In this figure, "Tsuru" is displayed in the column to the right of "Error location 1", and the trajectory data analysis unit 80V identifies the error type of "Error location 1" as "Tsuru". The guidance display control unit 80U displays it on the display unit 82.

In step ST64, a parameter candidate identified by step ST62 and matching the error type displayed on the display unit 82 is selected by step ST63 (see the item “Semi-automatic adjustment of operating parameters”), or a parameter candidate is selected. Select automatically (see "Automatic adjustment of operating parameters" section). For example, by default, the quality-oriented first mode may be set to be displayed on the display unit 82 first, and the quality-oriented parameter candidate may be automatically applied.

When the correction location selection button is pressed on the user interface screen shown in FIG. 41A, for example, a new user interface screen as shown in FIG. 42 is displayed, and an error is corrected for one error on the screen. Parameter candidates that reflect the level in four stages are displayed. Here, on the user interface screen shown in FIG. 42, the print time is displayed on the right side of each parameter candidate. This is because the operation parameter adjustment unit 80Z reads, for example, the adjustment parameter set corresponding to each parameter candidate from the storage unit 5A stored in advance on the user interface screen, and virtualizes the operation parameter of the selected processing disordered portion. Machining is executed, machining time is measured and displayed. In this example, when the user checks the radio button, the parameter candidate is selected.

In step ST65, the guidance display control unit 80U performs guidance display corresponding to the error type on the display unit 82. For example, when the "Done" button is pressed on the user interface screen shown in FIG. 41A, the user interface screen shown in FIG. 41B is displayed. For example, "Increase the waiting time to eliminate the hangers. Are you sure?" A guidance display (confirmation display) is displayed to the effect that the operation parameters corresponding to the error type are adjusted. When the "OK" button is pressed here, virtual machining is started with the adjusted operation parameters.

FIG. 43 shows another embodiment of the guidance display performed by the guidance display control unit 80U on the display unit 82. In this embodiment, "K", "D", and the two-dimensional code in the dotted line frame on the user interface screen shown in FIG. 43A are the places where the processing disorder occurs, and for this error type, " The deviation of the writing part of the block is increasing. Is it okay to increase the waiting time? ”Is displayed (confirmation display).

Next, in step ST66, the operation parameter adjustment unit 80Z reflects the adjustment parameter set corresponding to the parameter candidate selected through the above procedure in the operation parameter.

After executing step ST66, the process returns to step ST3, and steps ST3 to ST5 are executed again. In step ST5, if it is necessary to correct the machining disordered portion, the operation parameter is adjusted in step ST6, and if it is not necessary to correct it, the operation parameter is determined.

The user determines the operation parameters for each of the plurality of processing disordered parts to be corrected. Therefore, when there is another machining disordered part for which the operation parameter is to be corrected, the operation parameter at the machining disordered part is determined by designating the other machining disordered part in step ST61 and sequentially executing the above-mentioned steps. .. At that time, for the determined operation parameter for each machining disordered portion, virtual machining is executed with the operation parameter, and the machining time is measured and displayed, for example, as shown in FIG. 44. Note that, for example, after a plurality of machining irregularities are specified by the user and an error type is selected for each of them, virtual machining may be sequentially executed for the plurality of machining irregularities.

If there is no need for new correction of the processing disordered portion, the scanning control unit 80D opens the shutter of the shutter unit 71 so that the work WK is irradiated by the laser beam LB, and is generated by the development information generation unit 80C under the determined processing conditions. The laser light generating unit 6 and the laser light scanning unit 9 are controlled based on the developed information. As a result, the laser marking is actually performed, and the virtual machining is completed when the laser marking is completed.
(Procedure for semi-automatic adjustment of operating parameters)

The user can shift to the semi-automatic adjustment when the automatic adjustment does not give a satisfactory result or when he / she wants to make an advanced adjustment. In this semi-automatic adjustment, in the adjustment of the operation parameter by the operation parameter adjustment unit 80Z, the user manually selects the parameter candidate corresponding to the error type displayed on the display unit 82, executes the virtual machining, and obtains the virtual machining result. Based on this, the user determines the suitability of the selected parameter candidate. This procedure will be described in detail with reference to the flowchart of FIG.

First, in step ST101, the guidance display control unit 80U displays the user interface screen shown in FIG. 44 on the display unit 82. When the user presses the correction location selection button, for example, for one error, parameter candidates in which the correction level of the error is reflected in four stages are displayed. The user selects the parameter candidate 1 from among several parameter candidates and presses the "virtual print" button, so that the laser processing apparatus 100 performs virtual processing under the processing conditions of the parameter candidate 1.

In step ST102, the guidance display control unit 80U displays the machining time in the “block print time” column based on the virtual machining result, and the sum of the print times in the other print blocks is “total print time”. Display in the column of. Further, the locus display control unit 80Y displays the second locus ST, which is the virtual machining result, on the display unit 82.

In step ST103, the user confirms the display result and determines the suitability of the parameter candidate 1. When the user determines that the parameter candidate 1 is suitable, the user ends the adjustment of the operation parameter at the current location and proceeds to the adjustment at the next location (step ST111). When all the adjustments are completed, the laser processing apparatus 100 performs the actual laser marking.

When the user determines that the parameter candidate 1 is not suitable, the user can try the parameter candidate 2 by proceeding to the step of step ST104 and executing the same procedure as in steps ST101 to ST103. Further, in step ST106, the user determines the suitability of the parameter candidate 2.

Similarly, when the user determines that the parameter candidate 2 is not suitable, the user tries the parameter candidate 3 and determines the suitability of the parameter candidate 3 in step ST109.

In this way, the user can determine the suitability of the parameter candidates and select the desired parameter candidates, and can similarly select other processing disordered portions. Then, when the user does not obtain a suitable parameter candidate by the semi-automatic adjustment, the user proceeds to step ST110 and executes the manual adjustment. With this manual adjustment, more advanced adjustments can be made.
(Modification 2)

In the above procedure, the procedure of virtual processing with different parameter candidates is repeated until the user obtains parameter candidates that can be judged to be suitable. However, as shown in FIG. 46, first, virtual processing is performed with different parameter candidates. (Steps ST201 to ST203), the obtained plurality of virtual machining results may be displayed on the screen at once (step ST204), and suitable parameter candidates may be selected from the obtained plurality of virtual machining results (step). ST205).

The user can switch to manual adjustment if no suitable parameter candidates are available (step ST206). When a suitable parameter candidate is obtained, the adjustment proceeds at the next point (step ST207), and the actual laser marking is executed by the laser processing apparatus 100.

As described above, according to the present embodiment, it is possible to obtain the machining result and simplify the operation parameter adjustment work without actually performing the test machining by the virtual machining function.
(Processing pattern correction function)

Further, this laser processing apparatus has a function of correcting a processing pattern. As an example of the processing pattern correction function, there is a character string shift function that shifts the print coordinates of a character string to make it appear that the character strings are aligned when the coordinates of the printed character strings do not seem to be aligned. .. Here, the processing pattern is a character, and a plurality of processing patterns are character strings.

For example, FIG. 47B shows a print image in which the planned print character string shown in FIG. 47A is actually printed and the arc is reduced. As shown in these figures, there is no degeneracy in "1" and "4" in which the printed characters consist only of straight lines, but regarding "2", "3", and "5" including arcs. It can be confirmed that the arc part is degenerated inward. If you look at each character instead of a character string, you will not feel any discomfort even if it is degenerate. However, when viewed as a character string, "2" has a degenerate upper arc, so the characters appear to be lowered, and "3" and "5" have a lower arc, so the characters are degenerate. It looks up. For this reason, there is a problem that the character string positions do not seem to be neatly aligned.

Therefore, the present embodiment has a character string shift function that shifts the print coordinates of the characters so that the character strings appear to be aligned. The character string shift function can align the center of gravity of the character string, align the top edge and the bottom edge in the case of horizontal writing, align the right edge and align the left edge in the case of vertical writing, and the like. For example, FIGS. 48A to 48D show examples of a character string shift function for aligning the centers of gravity of character strings. When "12345" is set as the character string to be printed as shown in FIG. 48A, if it is printed as it is, it becomes as shown in FIG. 48B, and degeneracy is seen in "1" and "4" composed of only straight lines. However, with respect to "2", "3", and "5" including the arc, the arc portion is degenerated inward and the top and bottom are not aligned. Here, when the center of gravity BC of each number is calculated, it becomes as shown in FIG. 48B. Therefore, each character string is shifted as shown in FIG. 48C so that the center of gravity BC of each character is aligned on a straight line. As a result, the printed character strings are corrected so as to be aligned as shown in FIG. 48D, and the discomfort is reduced as compared with the printing result of FIG. 48B.

As a method of determining the center of gravity BC, as shown in FIG. 49 in the above example, a rectangle circumscribing each printed character is calculated, diagonal lines are drawn with respect to the four corners of the obtained circumscribed rectangle, and the intersection of the diagonal lines is set. It is the center of gravity. However, other methods can be used to determine the center of gravity. For example, in the example of FIG. 48B, since the purpose is to align in the horizontal direction, an intermediate position in the height direction of each character string may be obtained and used as the center of gravity.

The above character string shift function is realized by the reference position calculation unit 80E shown in FIG. 9 and the processing line segment data correction unit 80F for correcting the processing line segment data. The reference position calculation unit 80E calculates the reference positions of a plurality of processing patterns in the second locus based on the locus data generated by the locus data generation unit 80X. On the other hand, the processing line segment data correction unit 80F corrects the processing line segment data so that the reference positions of the plurality of processing patterns calculated by the reference position calculation unit 80E are aligned in a certain direction. As a result, the reference positions of the actually obtained processing patterns can be aligned, and high-quality processing results can be realized. The function of the reference position calculation unit 80E may be integrated into the locus data generation unit 80X so that the locus data generation unit 80X also calculates the reference position.
(How to adjust the print position)

Hereinafter, a procedure for adjusting the print position using the character string shift function will be described with reference to the flowchart of FIG. First, in step ST5001, a character string to be printed is input. The character string is input from the input section. Next, in step ST5002, the set character string is printed as a trial. This printing may be the virtual printing (virtual processing) described above, or may be printed on an actual printing object (work).

Next, in step ST5003, a reference position is calculated for each character with respect to the obtained character string. Specifically, in the case of virtual printing, the reference position calculation unit 80E calculates the reference position from the second locus generated by the locus data generation unit 80X. Here, the position of the center of gravity of each character is calculated as the reference position. When actually performing test printing, the reference position calculation unit 80E calculates the reference position of each character from the result obtained by printing. For example, the reference position is calculated by image processing for the image captured by scanning the test print result.

Next, in step ST5004, the processing position is corrected so that the reference position of each character is aligned in a certain direction. For example, when the reference position is the center of gravity, the coordinate position of the print data of each character is offset so that the center of gravity of each character is in the center of the character string. This process is performed by the processed line segment data correction unit 80F. Specifically, the processed line segment data correction unit 80F calculates the coordinates of the center of gravity of each character, checks whether it is located at the center of the character string arrangement, and if it is not at the center, calculates the difference between the center of gravity position and the center of the character string. Calculate and offset the print coordinates of this character according to this difference.

After that, in step ST5005, printing is performed based on the corrected print data. Here, as described above, virtual printing may be performed, or test printing may be actually performed. Then, in step ST5006, it is determined whether or not the reference positions of the characters are aligned in a certain direction. For example, if the position of the center of gravity is not aligned in the center direction of the character string arrangement, the process returns to step ST5003 and the abnormality setting is reset. That is, the work from the calculation of the reference position is repeated until the reference positions are aligned.
It should be noted that the determination as to whether or not the centers of gravity are aligned may be determined by the user visually confirming the print result or the like, or may be automatically performed by the apparatus side based on the calculation result. When it is determined that the reference positions are aligned in this way, the process proceeds to step ST5007, and the position correction of the character string is completed.
(Modification example)

In the above example, the character string shift function for aligning the printed character strings in the horizontal direction has been described. However, the present invention is not limited to this, and can be applied to, for example, a case of arranging in a vertical direction, an oblique direction, or an arc shape. Further, regarding the reference position, in the above example, the example in which the center of gravity is aligned on the center line along the sequence of the character strings has been described, but the present invention does not limit the reference position to the center of gravity, and other reference positions can be used. For example, the character string may be bottom-aligned or top-aligned. Further, when the character string is printed vertically instead of horizontally, it can be left-aligned or right-aligned. As an example, FIGS. 51A to 51C show an example of executing the character string shift function in bottom alignment. As shown in these figures, if "12345" set as the print schedule character string in FIG. 51A is printed as it is, the print result as shown in FIG. 51B is obtained due to the shrinkage of the arc, and this is the processed line segment data correction unit. When the character string shift function is executed so that the character strings are aligned at the bottom by 80F, the result is as shown in FIG. 51C, and it is possible to obtain a print result in which the lower ends of the characters are aligned.
(How to set the character string shift function)

Next, the procedure for setting such a character string shift function will be described based on the user interface screen of the laser processing condition setting program shown in FIGS. 52 to 55. FIG. 52 is a screen for setting a print block of a character string, and shows a state in which the “display” ribbon 490 is selected and the print block 0 composed of the character string “12345” is displayed in the edit display field 202 in two dimensions. ing. When the processing pattern correction function is called from this state, the print correction screen 500 of FIG. 52 is displayed.

To call the processing pattern correction function, for example, a method such as pressing the "print correction" button displayed on the toolbar 480 can be used. Further, the print correction screen 500 can be displayed in a window shape as shown in FIG. 52, and any mode can be used, such as providing a setting field for the processing pattern correction function in the user interface screen of the laser processing condition setting program. ..
(Print correction screen 500)

On the print correction screen 500, a portion to be corrected for printing is specified. In the example of FIG. 52, the print correction target print block selection field 502 is provided on the upper side of the print correction screen 500, and the user specifies the print block for which the print correction, here the character string shift function, is desired by the block number. FIG. 52 shows an example in which the print block 0 is specified.

In addition, since printing is performed by virtual printing in this example, the conditions for virtual printing are also specified. Here, a virtual print condition setting field 504 is provided on the lower side of the print correction screen 500, and the user selects a print block selected in the correction target print block selection field 502 as a print condition (virtual print condition) for virtual printing. Specifies the permissible print time and the total print time permissible for printing all print targets including this print block. When actual printing is performed instead of virtual printing, the printing conditions for actual printing are specified from the actual printing condition setting field or the like.

Further, it is possible to display a message for instructing the user of items to be set on the print correction screen 500. In the example of FIG. 52, the guidance display field 506 is provided at the upper part of the screen, and the guidance message "Correct the printing. Select the block to be corrected." Is displayed here. As a result, the user is instructed on the items to be set on the print correction screen 500, and even if he / she is unfamiliar with the operation, he / she can proceed with the setting without hesitation.

When the setting of the correction portion and the print condition is completed in this way, the "correction portion selection" button 503 is pressed on the print correction screen 500 of FIG. As a result, virtual printing (or actual printing) is executed, and the correction location selection screen 510 is called. Specifically, the second locus calculated by the locus data generation unit 80X is displayed in the edit display field 202 of the display unit, and further, as shown in FIG. 53, the correction location selection screen 510 is displayed. In this example, the correction location selection screen 510 is provided with an error location display field 512 and a correction instruction column 514.
(Correction part selection screen 510)

On the correction location selection screen 510, the character string to be corrected is specified, and the execution of correction is instructed. Here, the correction location is displayed, and the user specifies the correction target for each print block. The correction location is automatically calculated on the laser processing condition setting device side, for example. In this example, the laser processing condition setting device (or the laser processing condition setting program) automatically extracts the print block in which the print disorder exceeding the preset threshold value is generated and presents it to the user. There are a plurality of items in the print disorder. For example, when "balance of character strings" is targeted as an item of print distortion to be corrected, the degree of straightness of the line segment connecting the positions of the center of gravity and the standard that the positions of the centers of gravity of the characters constituting the character strings are not aligned are standard. Judging from deviations and the like, if these exceed the threshold value, it is determined that the printing is disturbed.
(Error location display column 512)

In the example of FIG. 53, assuming that the print block 0 lacks the balance of the character string, the print disorder (error) location 1 is listed in the error location display field 512 of the correction location selection screen 510, and the reason for the error (character string). Balance) is also displayed. Note that the print disorder is not limited to such a balance of character strings, and the size, inclination, distortion, etc. of each character may be included as a print disorder item. Extraction and determination of such print irregularities can be performed by the processing disorder extraction unit 80W.

Further, the character string corresponding to the error portion listed in the error portion display column 512 of the correction location selection screen 510 is highlighted on the edit display column 202. In the example of FIG. 53, the character string of the print block 0 listed as the error location 1 is displayed on the edit display field 202 surrounded by a broken line. Further, also in the error portion display field 512 of the correction location selection screen 510, the error portion 1 is displayed surrounded by a broken line. In the example of FIG. 53, only the print block 0 is displayed, but when a plurality of print blocks are set and a plurality of error points are detected, such a highlight pattern may be changed. Good. For example, the color of the broken line surrounding the print block on the edit display field 202 is changed to blue, red, yellow, green, etc., and the wavy line of the corresponding error part is also changed in each color in the error part display field 512. By displaying the error points, the user can easily visually grasp the correspondence even if there are a plurality of error points.
(Correction instruction column 514)

Further, the correction location selection screen 510 is provided with a correction instruction column 514 for designating the content to be corrected for each error portion. The correction instruction field 514 of FIG. 53 has a “correction candidate selection” button 515 and a correction method display field 516. The correction instruction column 514 is a member or means for the user to instruct whether or not to execute the machining pattern correction function (character string shift function), and if so, which correction to apply. The correction instruction field 514 displays an image of the processed processing pattern after correction as a candidate when a plurality of correction contents are executed by using the virtual print function described above, and the user desires the correction. It is configured to let you select the content. With this method, the user makes complicated settings such as which operation parameter to adjust and how much to obtain the corrected print pattern, or actually prints with that setting and operates based on the print result. There is an excellent advantage that the desired correction can be easily performed by simply selecting the corrected image without repeating trial and error of adjusting the parameters.
(Correction candidate display screen 520)

Specifically, when the "correction candidate selection" button 515 is pressed on the correction location selection screen 510 of FIG. 53, the screen switches to the correction candidate display screen 520 of FIG. 54, and a plurality of correction candidates in which different corrections are made to the character string are performed. (Correction candidate group) is displayed in a list in the correction candidate group display column 522. Here, as an example of the correction candidates displayed in the correction candidate group display field 522, the image 522a of the corrected processing pattern with the center of gravity aligned is performed on the left side of the correction candidate group display field 522, and the bottom alignment is performed on the right side. The image 522b of the processed processing pattern after the correction is shown. In this way, by actually displaying the corrected processing pattern as an image, it becomes easier for the user to visually grasp the correction content. Further, by displaying a list of processing patterns corrected by various correction methods in the correction candidate group display field 522, the user can select a desired processing pattern while comparing them. Then, the user selects the corrected processing pattern from these correction candidate groups with the radio button. Further, the selection method is not limited to this, and for example, a correction method may be specified by directly selecting a desired correction candidate from the correction candidate group with a mouse or the like. Further, each correction candidate is displayed with a print time allowed to print this print block. When the user manually changes the print time, the result of performing the same correction on the print result printed at the newly specified print time is displayed as an image.

In this example, two correction methods, center of gravity alignment and bottom alignment, are listed as correction candidates, but the number and types of correction candidates to be displayed in a list are not limited to this. For example, various correction methods such as top alignment or expansion / contraction to align the vertical size of characters can be mentioned. Further, in the correction candidate group display field 522, the correction candidate groups are arranged in the vertical direction, the screens are switched and displayed, or a plurality of correction candidate groups are displayed in an overlapping manner, so that the printing position can be slightly different. You can also make it understandable.

Further, in this example, "Character string balance" is displayed as a print disorder item to be corrected in the upper part of the correction candidate display screen 520, but it is possible to change this to another print disorder item, and the processing pattern is changed. It may be configured so that corrections other than aligning in the direction can be performed.

When the user selects a correction method and presses the "Done" button 524 on the correction candidate display screen 520 of FIG. 54, the screen returns to the correction location selection screen 510 as shown in FIG. 55. At this time, the display content of the edit display field 202 is updated to the corrected print pattern according to the selected correction method. As a result, the user can visually confirm the corrected print pattern. Further, the display contents of the correction method display field 516 of the correction instruction field 514 are updated according to the correction method selected on the correction candidate display screen 520. In the example of FIG. 55, the correction method display field 516 is displayed as "center of gravity alignment". In FIG. 53, since the correction method was not selected, it is "not corrected". As described above, the user confirms the corrected print pattern displayed in the edit display field 202, confirms that the intended setting has been obtained, and then presses the "Finish" button 518. As a result, the operation parameters corresponding to the selected correction method are automatically selected as the machining conditions, and the print conditions for actual printing are set. The selected machining conditions may be set, for example, to be executed at the timing when the "done" button 524 is pressed on the screen of FIG. 54.

In this way, the character string shift function makes it possible to easily perform correction work such as aligning the print patterns in a certain direction. That is, it is possible to significantly save labor in the adjustment work of repeating troublesome fine adjustment of operation parameters and test printing to approach the optimum printing result by trial and error. In particular, by using the virtual printing function, it is possible to easily obtain a desired printing result by reducing labor and cost without performing test printing on an actual sample.

In the example of FIG. 53, since there is one print block including the error portion, one correction instruction field 514 (“correction candidate selection” button 515 and correction method display field 516) is displayed, but a plurality of correction instruction fields 514 are displayed. When an error location is detected, a correction instruction column 514 is displayed at each error location. Further, in this example, the configuration is shown in which the error location is automatically extracted on the laser processing condition setting device (or laser processing condition setting program) side, but the present invention is not limited to this, and the target to be manually corrected by the user is not limited to this. It may be configured to specify the print block of.

In the above example, the error location is displayed for each print block, but it is not always limited to the end of the print block. For example, when a character string is printed in the horizontal direction across a plurality of print blocks, the balance between the print blocks arranged in the horizontal direction may be detected as a print disorder.

Further, in the above example, the configuration in which the user instructs the correction content from the correction instruction column 514 has been described, but the present invention is not limited to this configuration and is automatically performed on the laser processing condition setting device (or laser processing condition setting program) side. It may be configured to perform correction in a targeted manner. In this case, the processing line segment data correction unit automatically corrects the processing line segment data so that the reference positions calculated by the reference position calculation unit are aligned in a certain direction. The correction content is provided with a default value on the device side or is specified in advance by the user. For example, the processing line segment data correction unit is instructed in advance so that the character strings are bottom-aligned, top-aligned, and center-aligned, and the processing pattern correction function is executed according to the correction contents of the processing line segment data correction unit box. As a result, the correction work can be saved by automatically correcting the reference position in a certain direction on the laser processing apparatus side without adjusting the operation parameters and the like.
(Processing disorder batch correction function)

Further, as another function of correcting the processing pattern, this laser processing apparatus can also be provided with a batch correction function for collectively correcting the same print irregularities when processing a plurality of processing patterns. Examples of printing a plurality of processing patterns include pallet processing (also referred to as "step & repeat"). In pallet processing, in a state where a plurality of processing blocks are arranged, the processing content is changed for each processing block with the same processing content or a certain rule. For example, there are cases where the same manufacturing date is printed on a plurality of printing objects arranged in a matrix on a palette, or the serial number is incremented and printed.

As an example of such pallet processing, considering the case where a laser marker, which is an aspect of a laser processing device, is used to print on a plurality of objects to be printed, it is caused by the inertia of the galvano scanner motor and the mirror, the control tracking delay, and the like as described above. As a result, print distortion occurs that is slightly deviated from the desired print position. Therefore, in order to correct the print distortion, it is necessary to reduce the print speed or provide a waiting time (waiting time) before printing for each element to correct the print distortion. However, when there are a large number of characters and print blocks to be printed, the number of places where such adjustment work should be performed becomes enormous, which is a burden on the user and takes time. Further, although it is conceivable to automatically set the waiting time according to the distance from the previous printing unit to the next printing unit, the performance of the scanner may vary, or the X scanner or Y scanner may have different directions depending on the direction of the laser processing device. In some cases, the optimum setting could not be made due to changes in which one would be burdensome. Further, when a waiting time is provided to correct the printing disorder, if the waiting time is uniformly provided, the tact time required for printing increases and the work efficiency decreases. On the other hand, among the plurality of print irregularities, there are acceptable print deviations and prints that are not. For this reason, in the method of uniformly providing the waiting time, it is difficult to appropriately adjust the setting for shortening the printing time while allowing a certain amount of printing distortion when the number of printing units is large. Further, even if the waiting time is set for each print unit by taking time and effort, it cannot be set exactly properly unless it is set while actually printing and checking it many times.

Therefore, in the present embodiment, by providing the processing disorder batch correction function, necessary and sufficient print settings can be made without going through such complicated and laborious adjustment work. In particular, by combining the above-mentioned virtual printing function, it is possible to show the printing result to the user without actually printing and adjust the desired print quality, and the setting work can be easily performed even when there are many printing units. You will be able to do it in a short time.

In addition, in this specification, the collective correction for the second processing disordered portion is not limited to the mode in which one correction is uniformly performed for all the portions listed as the second processing disordered portion. .. That is, it also includes an embodiment in which a certain correction is performed on a part of the second processing disordered portion and another correction is performed on another portion of the second processing disordered portion. As described above, in the present specification, the batch correction for the second processing disordered portion is not limited to the simultaneous correction, but also includes a mode in which the correction is performed a plurality of times. For example, for the second machining turbulence location where the free running distance is equal to or greater than the threshold value, the corresponding corrections are collectively performed, while the locus data and the machining line segment at the first machining turbulence location specified by the machining turbulence extraction unit. A portion having a difference larger than the difference from the data may be set so as to add another correction to the portion extracted as the second processing disordered portion.
(Batch correction method for print distortion)

Here, a procedure for batch correction of print irregularities when performing palette printing will be described based on the flowchart of FIG. 56 and the user interface screen of the laser processing condition setting program of FIG. 57. In the palette print setting screen 300 shown in this figure, as shown in the edit display field 202 of FIG. 57, a matrix-like print element (cell) is set for a rectangular print object, and the pallet print setting screen 300 is composed of a plurality of cells. Consider an example in which each cell belonging to the octagonal print area is used as a print block, and a double circle is printed on each print block.

The printing conditions for pallet printing are, for example, in the processing condition setting unit 3C, the number of rows and columns of cells that are elements when performing matrix-like pallet printing, the contents to be printed on the cells, for example, specific printing. Specify a pattern or character string, a serial number or date to count up, a symbol (bar code, two-dimensional code, etc.) indicating this information. Further, the processing condition setting unit 3C may be provided with an arrangement setting unit 3W for setting the pallet processing conditions. For example, on the palette print setting screen 300 of FIG. 57, by pressing the "matrix" button provided on the toolbar, the array setting screen 280 as shown in FIG. 58 is displayed. The array setting screen 280 is an aspect of the array setting unit 3W, and the priority printing direction, the number of works (the number of rows and columns), the work interval, the reference position, and the like can be set. Specifically, the setting is made from the palette print tab 287.

First, in step S5601, virtual printing (virtual palette printing) is performed with the palette printing conditions set. In the virtual printing, as described above, the object to be printed is not actually printed, but only the laser light scanning unit 9 is scanned to acquire the scanning path. Such a scanning path can be generated and acquired from a scanner motor encoder and a position sensor.

FIG. 57 shows a state in which printing conditions for performing virtual palette printing are set, and the first locus FT constituting the set printing pattern is displayed in blue in the edit display field 202. Further, the print pattern input field 204 provided on the right side of the edit display field 202 is provided with various input fields for setting the details of the print conditions. Further, at the lower right of the screen, the second print correction screen 310 is superimposed and displayed in a window. The second print correction screen 310 includes a second processing block selection unit 312 for selecting a target processing block. In the example of FIG. 57, as the second processing block selection unit 312, the block number input field 313 for designating the print block to be corrected for printing and the print block of the block number specified in the block number input field 313 are used. A "correction location selection" button 314 is provided for selecting. Further, on the second print correction screen 310, a "virtual print" button 316 for executing virtual printing and a block print time designation field for designating a block print time which is an allowable print time for the designated print block are displayed. 317, an overall print time display field 318 and the like for designating an allowable time for overall printing are also provided. Virtual printing can be executed from this screen.

Next, in step S5602, the result of virtual palette printing is displayed on the display unit, and the first processing disorder portion is designated by the processing disorder designation unit 3Y. For example, a cell selection screen 320 (details will be described later in FIG. 64) as shown in FIG. 59 is displayed on the display unit, and a print block (cell) at which printing disorder is anxious is selected on this screen with a pointing device such as a mouse. Let me. In this example, a double circle is printed on each cell as shown in the partially enlarged view of FIG. 59 (details of the cell enlarged display field 330 for enlarging the cell will be described later in FIG. 64), which is optional. It is also possible to enlarge and display the second locus, which is the virtual print result, by selecting the cell of. Further, the selected cell can be enlarged and displayed on another screen as shown in FIG. 60. As shown in this figure, when printing so as to draw an inner circle after drawing an outer circle, even if the circles are concentric, printing is started before the laser light scanning unit 9 is settled. The center of the outer circle is printed out of position. Among a plurality of such print distortions, the print distortion to be corrected is specified.

Further, when the cells are enlarged and displayed, in addition to the mode of displaying each cell individually, as shown in FIG. 61, a plurality of cells may be virtually overlapped and displayed. As a result, the print misalignment is superimposed and displayed, and it is possible to easily confirm how the misalignment occurs.

It should be noted that the enlarged display and the separate screen display of the cell may be performed not only on the cell selected by the processing disorder extraction unit 80W, that is, the first processing disorder portion, but also on any other cell. This makes it possible to check the print status of each cell individually.

Alternatively, on the screen of FIG. 57, the user is made to select a portion (NG determination portion) that cannot be tolerated as a print disorder from the virtual palette print results displayed in the edit display field 202. Specifically, by pressing the "virtual print" button 316 on the screen of FIG. 57, virtual printing is executed, and the result of the virtual printing is displayed in the edit display field 202 as shown in FIG. 62. Here, as a result of performing virtual printing, the second locus ST of the locus data generated by the locus data generation unit 80X is displayed by the locus display control unit 80Y. Preferably, the locus display control unit 80Y superimposes on the first locus FT to display the second locus ST.
(Identification display function)

At this time, it is preferable to perform an identification display so that the first locus and the second locus can be distinguished. Therefore, the locus display control unit 80Y has an identification display function for discriminating and displaying the first locus and the second locus. For example, the explanations such as "first locus" and "second locus" are displayed on the first locus and the second locus with subscripts and leader lines, respectively, or due to the difference in line type (broken line, thick line, etc.) or legend. Display which is the first locus and which is the second locus. Alternatively, by displaying the first locus and the second locus with different colors, the difference between the two can be visually grasped. In this example, the first locus is displayed in blue, while the second locus is displayed in red. As a result, the user can visually grasp the difference between the originally intended first locus and the actually printed second locus. The identification display function also includes a highlighting function. For example, the second locus may be highlighted or the first locus may be grayed out to make one locus stand out from the other so that the two can be distinguished from each other. Further, the processing disorder display control unit 92 may also have the same functions as the identification display function and the highlight display function of the locus display control unit 80Y described above.
(Magnification adjustment unit)

Further, the print pattern displayed in the edit display field 202 can be enlarged or reduced. The magnification adjustment unit adjusts the display magnification in the state where the second locus is displayed in the display unit. In the examples of FIGS. 62 and 63, a magnification adjustment column 340 at the lower right of the screen is provided as the magnification adjustment unit. For example, when the display magnification is increased from the state of FIG. 62, the vicinity of the desired cell is enlarged and displayed as shown in FIG. 63. As a result, as shown in FIG. 63, it can be confirmed that the set print pattern is displaced and the virtual print is performed in the specific cell.
(Processing disorder designation part 3Y)

Therefore, the user specifies an unacceptable portion from such a virtual print result by the processing disorder designation unit 3Y. Of the second locus, the portion designated by the machining disturbance designation unit 3Y becomes the first machining disturbance portion, and this first machining disturbance portion is used as the reference for the machining disturbance. In the example of FIG. 63, a pointing device such as a mouse is used as the processing disorder designation unit 3Y, and the user specifies a desired portion in the edit display field 202.

Further, in this example, the first processing disordered portion is specified for each print block displayed in the edit display column. The print block designated by the processing disorder designation unit 3Y becomes the first processing disorder portion, and the subsequent automatic extraction of the machining disorder portion is executed based on the machining disorder included in the print block. At this time, the unit in which the processing disorder extraction unit 80W extracts the processing disorder portion can also be set for each print block. Further, the unit specified by the processing disorder designation unit 3Y and the unit extracted by the processing disorder extraction unit 80W may be a cell unit constituting the setting surface displayed in the edit display field 202. The cell is a rectangular area that constitutes a print area for palette printing. In the example of FIG. 63 and the like, the print block is in cell units. However, the print block can be set in an area different from the cell.
(Matrix edit screen 350)

Further, the processing disorder designation unit 3Y is not limited to the configuration shown in FIG. 63, and other configurations can be used. For example, as shown in FIG. 64, when an arbitrary cell is selected in the edit display field 202, the matrix edit screen 350 is displayed, and basic settings, layout, and other settings related to the matrix can be made. Here, when the "cell individual setting" button 352 is pressed from the matrix editing screen 350 of FIG. 64, the cell individual setting screen 360 is displayed. The cell selection screen 320 is displayed on the cell individual setting screen 360, and it is possible to select a desired cell from the cell selection screen 320 among the cells displayed in the matrix. Further, the details of the selected cell can be set in detail regarding the cell printing conditions in the cell detailed setting field 362 provided on the right side of the cell individual setting screen 360. Further, a cell enlarged display field 330 shown in FIG. 60 or the like is provided below the cell detailed setting field 362. In this way, the user can easily select any cell in which processing disorder is anxious, and can further adjust the printing conditions for each cell.
(Processing disorder extraction unit 80W)

Next, in step S5603, the second machining disorder portion is automatically extracted and displayed as a portion corresponding to the machining disturbance larger than the first machining disturbance portion. Then, the extracted second processing disordered portion is displayed on the display unit by the processing disorder display control unit 92 in a mode identified as the first locus.

Here, the machining turbulence extraction unit 80W is larger than the first machining turbulence portion designated by the machining turbulence designation unit 3Y based on the locus data indicating the second locus and the machining line segment data defining the first locus. The part corresponding to the processing disorder is automatically extracted from the virtual print result as the second processing disorder part.
(Extraction standard setting unit 3X)

The standard for determining the magnitude of the processing disorder by the processing disorder extraction unit 80W, in other words, the extraction standard for extracting the second processing disorder portion, is an operation in which processing disorder is likely to occur, for example, the sky in which the scanner is moved without emitting laser light. The length of the mileage, the radius of curvature when printing an arc, etc. can be used. Further, the extraction standard setting unit 3X may be provided for the user to manually set the extraction standard or adjust the set value. .. Further, the extraction standard setting unit 3X can select or change the extraction standard of processing disorder from a plurality of options, and can set the detailed conditions of the selected extraction standard. For example, when the free running distance is set as the extraction standard, the length of the free running distance can be increased or decreased by the extraction standard setting unit 3X.

Further, the extraction standard for extracting the second processing disordered portion may be defined in advance on the laser processing apparatus or the laser processing condition setting apparatus side. In addition, the user may make adjustments from the initial value of the extraction standard once set.

According to the extraction standard set in this way, the second machining disordered portion is extracted by the machining disorder extraction unit 80W, and further, the machining disorder display control unit 92 displays it on the display unit in a mode identified as the first locus. For example, in the example of FIG. 64, the length of the free running distance in the designated print block, which is the first machining disorder designated portion designated by the machining disorder designation unit 3Y, is used as an extraction standard, and the free running distance is larger than this free running distance except for the designated print block. The processing disorder extraction unit 80W extracts a long print block as a second processing disorder location. Then, as shown in FIG. 65, the extracted print block is identified and displayed on the display unit. Here, the corresponding print block including the designated print block is colored in red for identification display.

Alternatively, also in the example of FIG. 63, similarly, the length of the free running distance in the designated print block which is the first machining disordered portion is used as an extraction standard, and the printing block longer than this free running distance is used as the second machining disordered portion. The extraction unit 80W extracts, and as shown in FIG. 66, the extracted print block is identified and displayed on the display unit. Here, the corresponding print block including the designated print block is highlighted in yellow. The designated print block may be displayed in a manner different from that of the other second processing disordered portion. Further, the processing disorder display control unit 92 identifies and displays each print block. However, for example, the portion of the second locus corresponding to the processing disorder may be displayed in bold or colored to be emphasized.

Next, in step S5604, the extraction standard setting unit 3X adjusts the extraction standard as necessary. For example, the user confirms whether or not the second machining disordered portion displayed on the display unit is correctly extracted or selected, and if further adjustment work is required, the extraction reference setting unit 3X performs adjustment. Specifically, the width of the extracted range is adjusted. As described above, the extraction standard setting unit 3X can be used not only for setting the initial conditions of the extraction standard but also for adjusting or resetting the extraction standard based on the extraction result of the actual second processing disordered portion.

As an example, the extraction range can be changed by adjusting the length of the free running distance with the extraction reference setting unit 3X. For example, in the example of FIG. 67, the free running path is indicated by a broken line arrow, and a cell having a free running distance of 9 cells or more for moving the laser light scanning unit 9 in a state where the laser light is not emitted is red in the display unit. It is shown by. From this state, if the free-running distance is changed as an extraction reference, the range of cells to be extracted changes. For example, assuming that the free running distance is 19 cells, as shown in FIG. 68, more cells will be extracted as the second processing disordered portion.

Such adjustment of the extraction standard is performed by the extraction standard setting unit 3X. Further, when the value of the extraction reference is adjusted, the result of extracting the second processing disordered portion on the display unit may be configured to change in real time. For example, when the value of the free running distance is increased or decreased by using the up and down keys on the keyboard, the extraction result is updated in real time on the display unit accordingly.

Further, the result of virtual printing of each cell can be enlarged or displayed on a separate screen on the display unit. As shown in FIG. 60 and the like described above, the virtual print result of the cell selected on the cell selection screen 320 can be enlarged and displayed. Here, by moving the cell to be enlarged with the arrow keys of the keyboard or the like, the enlarged display is updated for each selected cell as shown in FIG. 69. As a result, the extraction reference setting unit 3X can be adjusted so that the virtual print result of the desired cell is corrected, that is, the extraction is performed as the second processing disordered portion while checking the virtual print result of each cell.

In this way, when the second processing disorder portion for batch correction of print distortion is selected as desired by the user, then in step S5605, the necessary batch correction conditions are set. Here, wait processing and scan speed deceleration processing are added automatically or manually before the selected cell. The wait process is a process of temporarily stopping the movement of the laser beam scanning unit 9 at the scanning position. The scan speed reduction process is a process for slowing down the scanning speed of the laser beam. By inserting such a process, the inertia of the laser light scanning unit 9 can be suppressed and printing disturbance can be reduced. However, if weight processing and deceleration processing are uniformly added, the printing result is improved, but the processing time is uniformly slowed down and the productivity is lowered. Therefore, by inserting the weight processing and the deceleration processing only in the places where the printing result is unacceptable, it is possible to improve the quality of the printing processing while suppressing the increase in the tact time.

When the batch correction is set in this way, the virtual palette printing is executed again in step S5606. Then, in step S5607, the virtual print result after the batch correction is displayed on the display unit, and the user is made to determine whether or not the result after the batch correction is satisfied. The user confirms the virtual print result for each cell in the same manner. For example, in the cell extracted as the second processing disordered part, it is confirmed that the virtual print result is corrected as shown in FIG. 70 from the state of FIG. 69, and the process is terminated if the user's satisfactory result is obtained. To do. On the other hand, if a satisfactory result is not obtained, the process returns to step S5602 and the above process is repeated.

In the above example, an example of performing virtual printing in which the laser beam is scanned without performing the actual printing has been described, but the present invention is also applied to the actual printing in which the laser beam is actually emitted to perform printing. Needless to say, you can do it.
(Modification example of printing disorder batch correction method)

In the above method, as an example of a method for collectively correcting print irregularities, a method of decelerating or temporarily correcting the scanning speed (scanning speed) of the laser light scanning unit 9 has been described, but the method of batch correction is limited to this. Alternatively, or in addition to this, other methods may be applied. As an example, an example of changing the machining order will be described as a modification based on the flowchart of FIG. 71. First, in step S7101, virtual palette printing is performed, in step S7102, the result of virtual palette printing is displayed, the first machining disordered portion is specified, and in step S7103, the second machining disordered portion is automatically extracted. These procedures are the same as those in steps S5601 to S5603 of FIG. 56 described above.

Next, in step S7104, it is determined whether or not the processing order may be changed. Here, when the machining disorder is reduced by changing the machining order, the user is made to determine whether or not such a change in the machining order is allowed. It should be noted that the case where the processing disorder is reduced by changing the processing order typically corresponds to the case where the free running distance of the laser beam scanning unit 9 is shortened by changing the printing order. If the change in the processing order is not allowed, the process proceeds to step S7106, and in steps S7106 to S7109, the same processing as in steps S5604 to S5607 of FIG. 56 described above is performed.

On the other hand, if it is permissible to change the machining order, the process proceeds to step S7105 to optimize the machining order. Specifically, the processing order is changed so that the free running distance is shortened. For example, as shown in FIG. 72A, in the case of an order in which cells arranged in a matrix are sequentially printed row by row from left to right, and when a line break occurs, the cells are returned to the left end and printed again. A free running distance will be generated every time. Therefore, as shown in FIG. 72B, once the right end is reached, when moving to the next line, printing is performed from the right end to the left end, and after reaching the left end, when moving to the next line, the left end will be used in the future. By moving the cell in a zigzag manner so as to move from to the right end, the free running distance can be significantly reduced.
(Scanning path changing unit 86)

Further, such a change in the machining order can be performed manually by the user, or a preferable machining order can be calculated and presented to the user to induce the user to change the machining order. For example, in the example shown in FIG. 9, the control unit 80 includes a scanning path changing unit 86. The scanning path changing unit 86 guides the change of the scanning path so that the free running distance for moving the laser light scanning unit 9 in a state where the laser light is not emitted is shortened. The scanning path changing unit 86 presents to the user an example of changing a preferable machining order. For example, the changed scanning path as shown in FIG. 72B is displayed on the display unit to prompt the user to change. When the user instructs the operation of changing the scanning path by pressing OK when accepting the change of the scanning path, the scanning path is changed accordingly and the user is instructed to process in the changed scanning order. Will be done.

The scanning path changing unit 86 can also be operated when the machining conditions are set. For example, before executing virtual printing, when setting the initial conditions of machining conditions, the scanning path changing unit 86 may be operated to execute virtual printing with the optimum scanning path set in advance. Good. Further, the scanning path changing unit 86 may have an optimum setting of the machining order, or a guiding function for guiding the machining order to the optimum machining order when the machining order is changed after the setting.

When the processing order is optimized in this way, the process proceeds to step S7106, and the extraction criteria are adjusted as necessary. Further, in step S7107, the conditions for batch correction are set, and in step S7108, virtual palette printing is executed again, and in step S7109, it is determined whether or not the result of the corrected virtual printing is satisfied. These procedures are the same as those in steps S5604 to S5607 of FIG. 56 described above.
(Histogram display function)

In the above example, a method of directly designating the first machining disordered portion on the image of the virtual machining result displayed on the display unit by the user has been described. However, the present invention is not limited to this configuration, and the distribution of the difference amount between the locus data showing the second locus in a plurality of machining patterns and the machining line segment data defining the first locus is displayed as a histogram, and is displayed on this histogram. It can also be configured to specify the amount of difference. Such an example will be described as a modified example based on the flowchart of FIG. 73. First, in step S7301, virtual palette printing is performed. This operation is the same as step S5601 and the like in FIG.
(Histogram display control unit 94)

Next, in step S7302, the amount of deviation between the first locus and the second locus is calculated from the result of virtual palette printing and displayed as a histogram. This process is performed by the histogram display control unit 94. The histogram display control unit 94 calculates the difference amount (deviation amount) between the trajectory data indicating the second trajectory and the processed line segment data defining the first trajectory, and further displays the frequency, that is, the distribution of the difference amount as a histogram. Let me. An example of such a histogram is shown in FIG. The histogram 370 may be displayed as a screen separate from the cell individual setting screen 360 as shown in FIG. 75, or may be integrated and displayed in the cell individual setting screen 360 as shown in FIG. 76. May be good.

The calculation of the difference amount between the first locus and the second locus may be performed by the histogram display control unit 94 or, as described above, by the difference calculation unit 96. In this case, the difference calculation function can be omitted from the histogram display control unit 94.

Further, in step S7303, the user is made to specify the first processing disorder portion on the histogram 370 displayed by the histogram display control unit 94 in this way. Here, the machining disorder range that defines the machining disorder to be collectively corrected is specified from the machining disorder designation unit 3Y. For example, from the top of the histogram 370 in FIG. 74, the machining disorder range 372 is designated as the first machining disorder portion as shown in FIG. 77. Such designation can be performed by a method such as designating a rectangular processing disorder range 372 with a pointing device such as a mouse. When the primary machining disturbance location is specified in this way, cells belonging to the frequencies included in the designated machining disturbance range 372 are extracted accordingly, and as shown in FIG. 78, on the cell selection screen 320. The corresponding cell is identified and displayed by the processing disorder display control unit 92. The designation of the machining disturbance range 372 on the histogram 370 may be displayed as a screen different from the cell individual setting screen 360, as shown in FIG. 79, or as shown in FIG. 80. , The cell individual setting screen 360 may be integrated and displayed. Similarly, the cell selection screen 320 of FIG. 78 can be appropriately displayed in the manner shown in FIGS. 79 and 80. Further, on the cell selection screen 320 of FIG. 78, an arbitrary cell is selected and enlarged and displayed, or as shown in FIG. 61, a plurality of cells are virtually overlapped and displayed to check the deviation amount. There are also things.

When the first machining disordered portion is specified in this way, in step S7304, it is determined whether or not the printing order may be changed, and if it is not acceptable, the process proceeds to step S7306, and if it is acceptable, in step S7305. Change the print order. Further, in step S7306, the extraction criteria are adjusted as necessary, in step S7307, the conditions for batch correction are set, in step S7308, virtual palette printing is performed again, and in step S7309, is the machining result satisfactory? It is determined whether or not the process is satisfied, and if the process is not satisfied, the process returns to step S7302, and the above process is repeated. These steps S7304 to S7309 are the same as steps S7104 to S7109 of FIG. 71 described above.

In this way, since the machining irregularities can be automatically extracted based on the extraction criteria, it is possible to save the user the trouble of manually specifying all the machining irregularities one by one, and especially in the scene where there are many machining irregularities, the more the parts are processed. It can contribute to simplification of work and shortening of work time. In particular, since the second machining disorder portion automatically extracted by the machining disorder extraction unit 80W can be collectively corrected by the machining disorder batch correction unit 84, all machining disturbances can be manually corrected. It is possible to save labor for correction one by one, and it can be expected that the correction work will be significantly reduced, especially in a scene where there are many parts to be processed.
(Extraction standard setting unit 3X)

In the above example of the flowchart, a mode has been described in which the user designates the first machining disorder portion from the machining disturbance designation unit 3Y, and the machining disturbance extraction unit 80W extracts the second machining disturbance portion according to the designation. However, the present invention is not limited to this aspect, and the extraction reference setting unit 3X can be used on the laser processing device or the laser processing condition setting device side without the user designating the first processing disorder location on the display unit in the processing disorder designation unit. The second processing disordered portion may be extracted according to a designated extraction standard. Further, the machining disorder extraction unit 80W may be configured to automatically extract machining disorder candidate locations and prompt the user to specify. In this case, the machining disorder extraction unit 80W extracts the machining disorder candidate locations that are candidates for the machining disturbance according to the extraction criteria set in advance by the extraction standard setting unit 3X, and extracts the extracted machining disturbance candidate locations as the machining disturbance. It is displayed on the display unit by the display control unit 92. In this state, the user selects, if necessary, the part to which the processing disorder is to be collectively corrected, determines the second processing disorder part to be corrected, and further performs the necessary adjustment work from the operation parameter input unit. , Perform batch correction by the processing disorder correction unit. Further, when displaying a machining disorder candidate portion that is a candidate for machining disorder on the display unit, the machining disorder display control unit 92 can distinguish the machining disorder candidate location from others, for example, as shown in FIG. 66. The cell corresponding to the candidate location may be colored and displayed so that the user can visually grasp the portion where the processing disorder is corrected.

Further, a guidance function may be provided to prompt the user to manually specify a portion corresponding to the machining disorder in the second locus displayed on the display unit.

Further, without such manual designation, the machining disorder extraction unit 80W may be configured to automatically extract the machining disorder candidate portion according to the extraction reference setting unit 3X and prompt the user to specify. For example, the machining disorder batch correction unit 84 automatically adjusts the machining conditions for the second machining disorder portion automatically extracted by the machining disorder extraction unit 80W. As a result, the second machining disordered part similar to the part designated as the first machining disordered part by the user in the machining disorder specifying part is automatically extracted without the user adjusting the operation parameters, and the correction is also automatically performed. This makes it possible to further save labor in the correction work.

In the above example, the cells of the object to be processed are arranged in a grid pattern in the vertical and horizontal directions as shown in FIG. 81A, but the arrangement pattern of the pallet processing is not limited to this, and the rows are as shown in FIG. 81B, for example. The offset arrangement may be performed such that the arrangement is shifted every time, or the arrangement is shifted vertically as shown in FIG. 81C. Further, it can be arranged diagonally as shown in FIG. 81D. Further, the outer shape of the area to be palletized is not limited to a rectangular shape, but also includes a circular shape and a fan shape.

Further, in the above example, the case where one machining block is set for each cell has been described, but the present invention is not limited to this embodiment, and for example, a plurality of machining blocks (lot numbers at different positions, manufacturing) in one cell. Set the date (when printing the manufacturer's logo, etc.), or conversely, include multiple objects to be processed in one processing block (when displaying two workpieces side by side and one design, etc.). You can also.

Further, the above-mentioned processing disorder batch correction function is not limited to the case of pallet processing, and when the same processing content is repeated or when processing is repeated while changing the processing content according to a certain rule (for example, printing while counting up the serial number). Needless to say, it can also be applied to such cases.

The laser processing apparatus, laser processing data setting apparatus, laser processing apparatus setting method, laser processing condition setting program, computer-readable recording medium and recording equipment of the present invention include, for example, marking, drilling, trimming, scribing, and surface treatment. In the process of irradiating the surface of a solid having a three-dimensional shape with a laser, it can be widely applied to set processing conditions. Although an example of a laser marker capable of three-dimensional printing has been described, the present invention can be suitably applied to a laser marker capable of two-dimensional printing.
