1 is a block diagram showing a schematic configuration of a laser processing system according to a preferred embodiment of the present invention.

Figure 2 is a view for explaining the concept of the cutting line width, Figure 3 is a view for explaining the concept of the marking line width and marking depth.

Among various quality items indicating the laser processing quality of the object F to be processed, the type of quality item capable of adjusting the degree of quality by using the laser processing system 1 is not particularly limited. For example, quality items that can control the degree of quality using the laser processing system 1 include a cutting line width, a marking line width, a marking depth, a marking color, and the like.

First, referring to FIG. 2 , the cutting line width Wc means the width of the tapered surface Fi constituting the cut surface of the object F when laser cutting processing is performed, but is not limited thereto. . In general, when laser cutting processing is performed, the processing object F is cut so that the cutting surface is inclined, the cutting surface of the processing object F is composed of a tapered surface Fi, and the upper end of the tapered surface Fi is the processing object (F) The generated shoulder (S: Shoulder) is formed by thermal deformation by the laser beam LB.

However, in general, the quality of the laser cutting process is related to the inclination angle (θ) of the taper surface (Fi). In addition, the inclination angle θ of the tapered surface Fi is the width Wc of the tapered surface Fi, that is, one end of the tapered surface Fi and the other end of the tapered surface Fi opposite to the one end of the processing object F ) is generally proportional to the distance spaced apart in the horizontal direction. Accordingly, the cutting line width Wc may be a quality item indicating the quality of laser cutting processing.

However, in general, the quality of the laser marking process is related to the distance between the shoulders (S). Accordingly, the marking line width (Wm) may be a quality item indicating the quality of laser marking processing.

Next, referring to FIG. 3 , the marking depth (Dm) means the depth of the groove (G) formed at the processing point to which the laser beam (LB) is irradiated when laser marking processing is performed, but is limited thereto it is not

However, in general, the quality of the laser marking process is related to the depth of the groove (G). Accordingly, the marking depth (Dm) may be a quality item indicating the quality of laser marking processing.

Next, the marking color may mean the color of the processing point to which the laser beam LB is irradiated when the laser color marking processing is performed during the laser marking processing.

However, in general, the quality of laser color marking processing is related to the color applied to the processing point by the laser beam LB. Accordingly, the marking color may be a quality item indicating the quality of laser color marking processing.

4 is a perspective view showing the schematic configuration of the processing machine shown in FIG.

The processing machine 20 is provided to irradiate the laser beam LB to the processing object F so that the processing object F can be laser processed in various processing methods (cutting processing, marking processing, etc.).

The structure of the processing machine 20 is not specifically limited. For example, as shown in FIG. 4 , the processing machine 20 includes a seating plate 21 on which the processing object F is seated, and a processing object seated on the seating plate 21 and the seating plate 21 ( An XY stage 12 for transferring F) in at least one of the X-axis direction and the Y-axis direction, a laser oscillator (not shown) that generates and oscillates the laser beam LB, and the laser beam LB oscillated by the laser oscillator ) by condensing and irradiating the object to be processed (F) seated on the mounting plate 21, and a laser head 23 for laser processing the object to be processed (F), and the laser head 23 in the X-axis direction and the Y-axis direction It may include a head driver (not shown) and the like for transferring in at least one direction.

The structure of the XY stage 12 is not specifically limited. An X-axis feeder 24 for transporting the processing object F seated on the seating plate 21 and the seating plate 21 in the X-axis direction, and the X-axis feeder 24 and the X-axis feeder 24 It may include a seating plate 21 coupled to the Y-axis feeder 25 for transporting the object (F) in the Y-axis direction, and the like.

In addition, the laser head 23 switches the optical path of the laser beam LB to any one of the X-axis direction and the Y-axis direction to irradiate the laser beam LB to the scan area As having a predetermined area. It is preferably composed of a scan head that can be used, but is not limited thereto.

As such, as the processing machine 20 is provided, the XY stage 12 transports the object F to be processed in at least one of the X-axis direction and the Y-axis direction, and the laser head 23 is transported by the XY stage 12 . The laser beam LB can be irradiated to the object F to be processed. Through this, the processing machine 20 may manufacture a product by laser processing the object F to be processed.

Next, the photographing module 70 is provided to photograph the laser-processed object F by the processing machine 20 . To this end, the photographing module 70 may include at least one camera (not shown) capable of photographing the laser-processed object F processed by the processing machine 20 .

6 is a view for explaining a method of setting a processing design of an object to be processed and a reference quality of a quality item.

In step S10, the processing design D of the processing object F and the reference quality of a predetermined quality item are set.

First, the processing design D of the object F for laser processing is set. The processing design (D) of the processing object (F) corresponds to the design of the product for manufacturing by laser processing the processing object (F), and the processing shape corresponding to the shape of the product to be manufactured using the processing object (F) It can be arranged to have For example, as shown in FIG. 6 , in the case of manufacturing a display panel for a mobile phone by laser cutting the object to be processed (F), the processing design (D) is processed corresponding to the shape of the display panel for a mobile phone It may be provided to have a shape.

As shown in FIG. 6 , the machining shape of the machining design D may be defined by at least one machining plan pattern E. As shown in FIG. By the way, in order to manufacture a product by laser processing the processing object F, the laser beam LB is applied to the processing object F according to the shape and type of the product and the type of laser processing required for manufacturing the product ( line) irradiating in the form of a line, and point processing in which the laser beam LB is irradiated to the object F to be processed in the form of a spot, etc. may be performed. Accordingly, the processing schedule pattern E may be composed of at least one of a line and a dot.

In addition, the processing schedule pattern (E) may include a plurality of sections having the same or different shapes, such as a straight section or a curved section, depending on the machining shape of the machining design (D). According to this processing schedule pattern (E), by irradiating a laser beam (LB) along the processing schedule pattern (E) to the processing object (F) using the processing machine 20 and laser processing the processing object (F), the processing object ( The product can be manufactured from F).

In addition, the method of setting the processing design (D) is not specifically limited. For example, the operator manually inputs the processing design D into the storage module 30 or the setting module 50 using the input module 40, or sets the design data previously stored in the storage module 30 to the setting module ( 50) can be uploaded and set.

The structure of the input module 40 is not particularly limited. For example, the input module 40, while displaying the driving state of the laser processing system 1 and other various data as an image, the control signal of the laser processing system 1, and other various data can be input It may be provided with a touch screen provided to be able to. In this case, the input module 40 may also function as the display module 60 .

Next, by using the laser processing system 1 among the quality items, the level of quality, that is, the reference quality of a specific quality item for which the quality value is to be adjusted is set. The reference quality means a reference quality value or a reference quality value range that can be recognized that the laser processing quality for the specific quality item is good, but is not limited thereto. For example, as shown in FIG. 6 , in the case of adjusting the laser processing quality for the transmission line width using the laser processing system 1, the reference quality can be recognized that the laser processing quality for the cut line width is good. It may be a reference cut line width value or a range of reference cut line width values.

The method of setting the reference quality is not particularly limited. For example, the operator sets the reference quality by manually inputting the reference quality into the storage module 30 or the setting module 50 using the input module 40, or sets the quality data previously stored in the storage module 30 to the setting module 50 ) can be uploaded and set.

7 is a view for explaining a method of preparing a setting standard of a processing variable.

In step S 20, the setting criteria of each of the processing parameters of the laser processing system 1 are set according to the reference quality.

In general, the laser processing aspect of the processing object (F) may be different depending on the material and processing speed of the processing object (F). Accordingly, as shown in FIG. 7 , it is preferable that the operator preferentially set the material and processing speed of the object to be processed (F) before setting the setting criteria for each of the processing variables (S 22).

The method of setting the raw material and processing speed of the object F to be processed is not specifically limited. For example, the operator manually inputs and sets the material and processing speed of the processing object F into the storage module 30 or the setting module 50 using the input module 40, or the storage module 30 ) can be set by uploading data about the material and processing speed of the processing object F stored in advance to the setting module 50 . The controller 10 selectively drives the processing machine 1 based on at least one of the material and processing speed of the processing object F set as described above when performing the first and second test processing to be described later, thereby improving the laser processing quality can do it

On the other hand, the processing variable refers to various factors that can affect laser processing quality, such as a factor for the characteristics of the laser beam LB and a factor for the laser processing environment. Accordingly, the operator sets the reference quality in step S 10 among various processing variables of the laser processing system 1 so that the operator can selectively adjust the quality value of the specific quality item for which the reference quality is set in step S 10 . It is possible to selectively set the setting criteria of each of the variable variables affecting the quality value of the item (S 24).

For example, if the standard quality for the cutting line width is set in step S10, the processing variables are the power (W), frequency (kHz), pulse width (㎑), duty ratio of the laser beam (LB). , %) and focal length (mm), and the pressure of the assist gas (Bar), and the like. Here, the assist gas is a gas that is injected to the processing point to which the laser beam LB is irradiated during laser processing, and the material melted, decomposed, and evaporated by the laser beam LB may be separated from the processing point. The assist gas is preferably an inert gas, but is not limited thereto.

The content included in the setting criteria of each of the processing variables is not particularly limited. For example, the setting criteria of each of the processing variables may include a minimum set value (Min), a maximum set value (Max), and a unit interval.

The minimum set value Min may correspond to a test set value with the smallest absolute value among test set values of a machining variable included in a machining recipe. Correspondingly, the maximum set value Max may correspond to the largest absolute value among test set values of the machining variables included in the machining recipe. The minimum set value Min and the maximum set value Max may determine a setting range of test set values.

However, the storage module 30 may be stored so as to accumulate work data for various tasks performed using the existing laser processing system 1 . Accordingly, the setting module 50 is at least one of the processing design (D) and reference quality set in step S 10 and the material and processing speed of the processing object (F) set in step S 20 (hereinafter referred to as 'process conditions') and the work data accumulated in the storage module 30 are compared. In addition, the setting module 50 may set the minimum set value (Min) and the maximum set value (Max) of each of the processing variables based on the comparison result. However, it is not limited thereto, and the operator manually stores at least one of the minimum set value (Min) and the maximum set value (Max) of each of the processing variables using the input module 40 , the module 30 or the setting module ( 50) to set it.

The unit interval corresponds to the setting interval of setting values for testing of processing variables included in the processing recipe. Accordingly, since the number of test set values included in a processing recipe to be described later is determined according to the absolute value of the unit interval, the number of test set values may be adjusted by adjusting the unit interval. The setting module 50 may derive a unit interval of each of the processing variables based on the work data accumulated in the storage module 30 so that an appropriate number of test setting values are included in the processing recipe (see FIG. 7 ). See Autoset Unit Interval). However, the present invention is not limited thereto, and the operator may manually input and set the unit interval of each of the processing variables using the input module 40 into the storage module 30 or the setting module 50 (manual setting in FIG. 7 ). see unit spacing). For example, if it is determined that the number of test set values included in the processing recipe is excessive, the operator may manually reset the unit interval to reduce the number of test set values to an appropriate level.

In step S 30 , the setting module 50 divides the machining design D into a plurality of machining units U according to the machining shape of the machining design D.

Referring to Figure 8, when the processing schedule pattern (E) includes a plurality of sections having different shapes, such as a straight section and a curved section, the setting module 50 sets the machining design (D) to the machining plan pattern (E) ) may be divided into a plurality of processing units (U) each including a section having a specific shape among the entire section and then stored in the storage module 30 .

For example, as shown in Fig. 8, the machining design (D) is R=2. At least one curved processing unit (U1, U3, U5, U7, U9, U11, U13, U15) having the same or different curvature, such as R=3, R=10, and at least one having the same or different length can be divided into linear machining units (U2, U4, U6, U8, U10, U12, U14, U16).

9 is a view for explaining a method of preparing a processing recipe for each of the processing units.

In general, laser processing quality may be changed according to the shape of the irradiation path of the laser beam LB, such as whether the irradiation path of the laser beam LB is a straight line or a curved line, the radius of curvature of the irradiation path of the laser beam LB, etc. . By the way, in the laser processing system 1, the irradiation path of the laser beam LB is determined according to the shape of the processing design D, ie, the processing schedule pattern E. FIG. Accordingly, even if the processing object (F) is laser processed while the processing variables are maintained at a constant value, the laser processing quality of the processing object (F) is the processing unit (U) due to the difference in the processing shape between the processing units ( U) may be different.

Accordingly, in step S 40, the setting module 50, the processing units (U) in accordance with the processing shape of each processing unit (U) to laser processing the same or different from each other, the processing units (U) ) can be stored in the storage module 30 after individually preparing a processing recipe for each.

For example, curve machining units with R=2 (U3, U9), curve machining units with R=3 (U5, U7), curve machining units with R=10 (U1, U11, U13, In the case of having four types of machining units (U) such as U15) and R=∞ linear machining units (U2, U4, U6, U8, U10, U12, U14, U16), the 4 types of machining units One for each (U), a total of four processing recipes may be provided.

The processing recipe refers to a data table in which test setting values for each processing variable are input in the form of a table. The test setting values of each of the machining variables are set values of each of the machining variables for performing the first test machining of the processing object F to be described later, and are set according to the setting criteria set in step S20 described above. Accordingly, the test set values for each of the processing variables include at least a minimum set value and a maximum set value, and the absolute value may be set to increase step by step from the minimum set value to the maximum set value by unit intervals. The number of test set values included in each of these machining recipes may be determined according to the minimum set value, the maximum set value, and the unit interval of each of the machining variables. Accordingly, the processing recipes may include the same or different number of test setting values.

In addition, as shown in FIG. 9 , a basic setting value of each of the processing variables may be additionally input to the processing recipe. The basic set value means a test set value that is expected to satisfy the standard quality of a predetermined quality item when laser processing is performed according to the test set value among test set values. The default setting value is preferably set individually for each processing recipe, but is not limited thereto.

The input method of the basic setting value is not specifically limited. For example, the setting module 50 compares the processing conditions and the processing shape of each of the processing units U with the work data accumulated in the storage module 30, and sets the basic setting value of each of the processing variables to the processing recipe After deriving each of them individually, it can be input to each of the processing recipes. However, unless limited thereto, the operator may manually input the basic setting value into the processing recipe using the input module 40 .

10 is a view for explaining a method of first test processing a processing object using the test setting values included in the processing recipe, and FIG. 11 is the test setting values included in the processing recipe using the first test processing result. It is a diagram for explaining a method of selecting a set value for mass production from among them.

In step S 50 , the controller 10 selectively drives the processing machine 20 using test setting values and basic setting values included in each of the processing recipes set in step S 40 to drive the processing object (F) The first test processing is performed on the , the photographing module 70 photographs the result of the first test processing, and the analysis module 80 analyzes the photographed image I of the result of the first test processing to obtain a predetermined quality Measure the quality value of the item.

First, the controller 10 individually performs the first test machining for each machining unit U (S 52). More specifically, in the first test processing, the laser beam LB is irradiated to the processing object F along a specific section of the processing schedule pattern E included in each processing unit U using the processing machine 20 . Through this method, it can be carried out individually for each processing unit (U). For example, as shown in FIG. 10 , the first test machining is performed individually for each machining unit (U) so that the results of the first test machining for each machining unit (U) are spaced apart by a predetermined interval. It is preferable to carry out, but is not limited thereto.

However, as shown in FIG. 8 , some of the machining units U among all machining units U may have the same machining shape. When there are a plurality of machining units (U) having the same machining shape as described above, the first test machining is selectively performed for only one machining unit (U) among machining units (U) having the same machining shape as each other. It is preferable to carry out, but it is preferable to be limited to this.

For example, as shown in FIG. 8 , there are two curve processing units (U3, U9) with R=2, two curve processing units (U5, U7) with R=3, and R=10. When there are 4 curved machining units (U1, U11, U13, U15) and 8 straight line machining units (U2, U4, U6, U8, U10, U12, U14, U16) with R=∞, R= Any of the two curve machining units (U3, U9), any one of the curve machining units (U5, U7) with R=3, and the curve machining units (U1, U11, U13, R=10) U15) and only one of the linear machining units (U2, U4, U6, U8, U10, U12, U14, U16) of which R=∞ may selectively perform the first test machining.

In addition, as shown in FIG. 10 , the first test machining for the specific machining unit U among the machining units U is a test included in the machining recipe for the specific machining unit U among the machining recipes. Repeatedly over a number of execution rounds to correspond to the number of set values for use.

For example, the first test machining for the curve machining units (U3, U9) with R=2 is the number of test set values included in the machining recipe for the curve machining units (U3, U9) with R=2 and It can be repeated over the same round of practice.

In addition, as shown in FIG. 10 , the first test machining for the specific machining unit U among the machining units U is the first test machining for the specific machining unit U formed on the machining object F. 1 It is preferable that the results of the test processing be carried out so as to be spaced apart from each other by a predetermined interval, but is not limited thereto.

In addition, the controller 10 uses a basic setting value for each of the remaining processing variables except for the specific processing variable among the processing variables as the setting value of each of the remaining processing variables, and sets the test for the specific processing variable The first test machining may be repeatedly performed over a plurality of execution cycles by selectively using any one of the test set values among the values as the set values of the specific machining variables in a predetermined order. Accordingly, by analyzing the results of the first test processing, it is possible to determine the influence of the change in the set value of the specific processing variable on the quality value of the predetermined quality item. The first test machining for determining the effect of the change in the set value of the specific machining variable on the quality value is repeated as many times as the number of test set values for the specific machining variable included in the machining recipe. it is preferable

For example, as shown in FIG. 11 , in the first test machining for determining the effect of power on the quality value, the set values of each of the machining variables other than the power among the machining variables are set to the default set value (frequency). 20 (㎑), pulse width 10.0 (㎲), duty ratio 30 (%), focal length 22.0 (mm), and gas pressure 5 (Bar), set the power set value to the minimum set value 20 (W) ) to the maximum setting value of 100 (W), by increasing the unit interval by 5 (W) stepwise, it can be repeatedly performed as many as 17 times, which is the same as the number of 17 set values for the test for power included in the processing recipe.

In addition, the order of inputting the test setting values is not particularly limited. For example, the setting module 50 may input the test setting value of any one of the test setting values of the processing variable to the controller 10 in an ascending order for each execution time of the first test processing.

When the first test processing is performed as described above, the laser processing quality of the result of each execution of the first test processing formed on the processing object F is the value of the specific processing variable selectively input for each execution of the first test processing. It can be determined according to the setting value for the test. Accordingly, when the results of the entire first test processing for each of the processing units U formed on the processing object F are compared and analyzed, the effect of the change in the setting value of each processing variable on the quality value of the predetermined quality item can be identified individually for each processing unit (U).

The first test machining is preferably performed by individually adjusting the set values of all machining variables according to the machining recipe, but is not limited thereto. For example, during laser cutting, only the setting values of some of the processing variables (eg, power (W), frequency (kHz)) are adjusted according to the setting values for testing on the processing recipe. Thus, the first test processing can be performed. For example, during laser marking processing, only the setting values of other processing variables (eg, pulse width (㎲), duty ratio (%)) of some of the processing variables are added to the test setting values on the processing recipe. The first test processing may be performed by adjusting accordingly.

Next, the photographing module 70, after photographing the results of the first test processing for each of the processing units (U) formed on the processing object (F), the photographed image (I) of the results of the first test processing It is stored in the storage module 30 (S54).

Thereafter, the analysis module 80 analyzes the result of the first test processing based on the photographed image I of the results of the first test processing photographed by the photographing module 70, and the result of the first test processing A quality value of a predetermined quality item for each of them is measured (S56). In addition, the setting module 50 inputs the quality value measured in this way to the corresponding part of the processing recipe so that the quality value is matched with the set value for the test used in a specific execution round of the first test processing in which the quality value is measured (S 58) .

For example, as shown in FIG. 11 , when the first test processing for the curve processing units U3 and U9 with R = 2 is performed, the setting module 50 is configured for the power test setting value. A quality value of 98.1 (μm) of a specific execution cycle of the first test machining limited to 30W may be input to the corresponding part of the machining recipe so as to match the power test set value of 30W.

By repeating the above process, quality values according to test set values for each processing recipe are measured and then inputted into the corresponding part of the processing recipe, thereby completing processing recipes.

Next, in step S60, the analysis module 80 selects quality values that satisfy the reference quality set in step S10 from among the quality values input to each of the processing recipes as satisfaction values, respectively, and then the storage module 30 ) is stored in (S62).

The method of selecting a satisfactory value is not specifically limited.

When the reference quality is the reference quality value, the analysis module 80 may select, among the quality values, quality values in which an error with the reference quality value is less than a predetermined first reference error, respectively, as a satisfactory value.

When the reference quality is within the reference quality value range, the analysis module 80 may select quality values that fall within the reference quality range from among the quality values as satisfactory values, respectively.

In addition, on the processing recipe, it is preferable to specify each of the fields in which the satisfaction value is described by a predetermined method. For example, as shown in FIG. 11 , in the processing recipe, the fields in which the satisfaction value is described may be specified by shading.

Next, the analysis module 80 selects, among the satisfaction values, satisfaction values determined to be particularly excellent in laser processing quality as excellent values, respectively, and the first test processing in which the quality value corresponding to the excellent value is measured. After specifying the test set value used in a specific execution round, it is stored in the storage module 30 (S64).

The method of selecting an excellent value is not specifically limited.

When the reference quality is the reference quality value, the analysis module 80 selects, among the satisfaction values, the satisfaction values that are less than the second reference error determined such that the error with the reference quality value is smaller in absolute value than the first reference error, respectively. value can be selected.

When the reference quality is within the reference quality range, the analysis module 80 may select, as excellent values, each of satisfaction values in which an error with a median value of the reference quality range is less than a predetermined third reference error. For example, as shown in FIG. 11 , if the reference quality value is in the range of 100 μm to 120 μm and the third reference error is ± 2 μm, the analysis module 80 determines that the cut line width value among the satisfaction values is 108 μm to 120 μm. Each of the satisfactory values belonging to 112 μm may be selected as an excellent value.

In addition, on the processing recipe, it is preferable to specify the columns in which the even values matched with each other and the set values for testing are described, respectively, by a predetermined method. For example, as shown in FIG. 11 , on the processing recipe, columns in which even values matched with each other and set values for testing are described may be specified as boxes, respectively.

Thereafter, the analysis module 80 performs a first test processing in which a quality value corresponding to an even value having the smallest error with the reference quality value or the intermediate value of the reference quality value range among the quality values is measured for each processing recipe. After selecting the test set value used in a specific execution round of , as the mass production set value, it can be stored in the storage module 30 (S 66). In addition, the analysis module 80 may store the set value for mass production in the storage module 30 after specifying the set value for which of the machining variables the set value for mass production is selected. For example, as shown in FIG. 11 , the analysis module 80 sets the test setting value 21.8 (mm) for the focal length at which the quality value 110.1 μm with the smallest error from the median value is measured as the focal length. It can be selected as the set value for mass production.

The set value for mass production is a specific processing unit (U) associated with the processing recipe including the set value for mass production among all the processing units (U) when the product is manufactured by actually mass-processing the processing object (F). It can be used as a set value of a processing variable associated with the set value for mass production when laser processing is performed.

On the other hand, the processing variable associated with the set value for mass production corresponds to a main processing variable that has a large influence on the quality value for the processing unit (U) associated with the processing recipe including the set value for mass production. Therefore, hereinafter, machining variables related to the mass production set value among all machining variables will be named target machining variables, and the remaining machining variables excluding the target machining variables will be referred to as normal machining variables.

12 is a view for explaining a method of performing a second test processing of an object to be processed using a set value for mass production selected from a processing recipe.

In step S 70 , the controller 10 selectively drives the processing machine 20 using the set value for mass production of the target processing variable selected in each of the processing recipes to perform the second test processing for the processing object F The imaging module 70 captures the result of the second test processing, and the analysis module 80 analyzes the photographed image I of the result of the second test processing to measure the quality value of a predetermined quality item .

First, as shown in FIG. 12, the controller 10 continuously irradiates the laser beam LB to the object F to be processed along the entire section of the pattern E to be processed using the processing machine 20, For a section belonging to a specific processing unit (U) among the entire section of the processing scheduled pattern (E), the processing machine 20 is operated according to the mass-production setting value of the target processing variable selected in the processing recipe for the specific processing unit (U). By selectively driving, the second test processing may be performed (S 72). That is, in the second test processing, the processing object F is laser processed so as to actually form a product, but for a specific processing unit U in which laser processing is currently in progress among all processing units U, the specific processing unit (U) It is carried out by selectively driving the processing machine 20 using the set value for mass production of the target processing variable selected in the processing recipe for the processing unit (U).

The method of performing the second test machining by selectively driving the machining machine 1 using the mass-production set value of the target machining variable is not particularly limited. For example, the controller 10, when laser processing a specific processing unit (U) of the processing units (U), as a set value of the target processing variable selected in the processing recipe for the specific processing unit (U) A set value for mass production may be used, and a basic set value of each of the normal machining variables may be used as a set value of each of the normal machining variables included in the machining recipe for the specific machining unit (U). Through this, the controller 10 selectively drives the processing machine 20 and other components of the laser processing system 1 using the set value for mass production of the target processing variable and the basic setting value of each of the normal processing variables, A second test machining can be performed for a specific machining unit (U).

Next, the photographing module 70 captures the result of the second test processing formed on the processing object F, and then stores the photographed image I of the result of the second test processing in the storage module 30 (S) 74).

Thereafter, the analysis module 80 divides and analyzes the captured image I of the result of the second test processing for each processing unit U, and individually measures the quality value of a predetermined quality item for each processing unit U do (S 76).

In step S80 , the analysis module 80 determines whether each of the processing units U is defective based on the analysis content of the result of the second test processing collected in step S70 .

Whether each of the processing units (U) is defective may be performed by individually determining whether the quality value of each of the processing units (U) measured in step S76 satisfies the reference quality.

For example, when the reference quality is the reference quality value, the analysis module 80 may compare the quality value of the specific processing unit U among the processing units U and the reference quality value. Thereafter, the analysis module 80, if the error between the quality value and the reference quality value is less than or equal to a predetermined reference error, a good determination that the laser processing quality of the specific processing unit (U) for the predetermined quality item is good (OK) can do. In addition, the analysis module 80, when the error between the quality value and the reference quality value exceeds the predetermined reference error, the laser processing quality of the specific processing unit (U) for the predetermined quality item is defective (NG) determination can do.

For example, when the reference quality is the reference quality range, the analysis module 80 may compare the quality value of the specific processing unit U among the processing units U and the reference quality range. Thereafter, the analysis module 80 may make a good determination that the laser processing quality of the specific processing unit U for a predetermined quality item is OK if the quality value falls within the reference quality range. In addition, the analysis module 80, if the quality value is outside the reference quality range, the laser processing quality of the specific processing unit (U) for a predetermined quality item may be determined to be defective (NG).

13 is a view for explaining a method of re-performing the second test machining by using the mass production set value reselected according to the second test machining result.

If there is a specific machining unit (U) that has been determined as defective during the second test machining among the machining units (U), mass-produced from among test set values included in the processing recipe for the specific machining unit (U) that has been determined as defective It is possible to reselect the set value for use (S 66).

For example, in the analysis module 80, the error between the reference quality value or the intermediate value of the reference quality value range among the remaining excellent values except for the excellent value matched with the test setting value previously selected as the mass production setting value is The test setpoint matched with the smallest odd value may be reselected as a new mass production setpoint of the processing recipe. That is, the analysis module 80, among the quality values input in the processing recipe for the specific processing unit (U), the standard quality next to the excellent value matched with the test setting value previously selected as the mass production setting value The test set value matched with the satisfactory excellent value may be reselected as a new mass production set value of the processing recipe.

On the other hand, it is preferable to maintain the set values for mass production for the remaining machining units (U) that have been judged good among the machining units (U), but is not limited thereto.

In addition, using the reselected set value for mass production, performing the second test processing (S72), photographing the result of the second test processing (S74), and analyzing the result of the second test processing The step (S76) of measuring the quality value of a predetermined quality item for each processing unit (U) and the step (S80) of determining whether each of the processing units (U) is defective can be sequentially re-performed have.

As a result of re-determination of whether or not defective, when all processing units U are judged as good, the selection of the set value for mass production is completed. This selected set value for mass production may be used as driving data for constantly maintaining the quality value of a predetermined quality item at a reference quality level when the product is mass-produced by laser processing the object (F).

As a result of re-determination of whether or not defective, if some of the processing units U are still determined to be defective, the step of re-selecting the set value for mass production (S 66), the step of performing the second test processing (72), the second test A step (S74) of photographing the processing result, a step (S74) of measuring the quality value of a predetermined quality item for each processing unit (U) by analyzing the result of the second test processing, and the processing unit ( U) The step (S80) of determining whether each is defective may be sequentially re-performed.

This laser processing system 1 divides the processing design D of the processing object F into a plurality of processing units U according to the processing shape, and then the reference quality of the predetermined quality item and the processing object ( Based on the process conditions including the material and processing speed of F), a processing recipe containing test set values for each of the processing variables affecting the quality value of a predetermined quality item is converted into processing units (U) automatically provided each time.

In addition, the laser processing system test-processes the processing units (U) in various ways by reflecting the test setting values included in the processing recipe for the processing unit (U), respectively, and then analyzes the results of the test processing. , a set value for mass production that most satisfies the standard quality among test set values of target machining variables and target machining variables that mainly affect the quality values of predetermined quality items is automatically selected for each machining recipe.

Conventionally, in order to improve the quality of laser processing, the operator repeatedly performs test processing while manually adjusting the setting values of the processing variables depending on the experience, and manually sets the mass production setting values of the processing parameters to apply to the mass production of the product. had to choose

Therefore, in the prior art, a lot of time and manpower were required to manually select the set values for mass production of the processing variables to be applied to mass production of products, and the processing object ( There was a problem in that the laser processing quality of F) was influenced.

By the way, according to the laser processing system 1, the set value for mass production of a processing variable can be selected automatically. Accordingly, the laser processing system can reduce the number of people and time required to select the set value for mass production of the machining variable, and accurately select the set value for mass production of the machining variable according to the process condition regardless of the skill of the operator F) can improve the laser processing quality.

In addition, the laser processing system uses a processing recipe individually prepared for each of the processing units U of the processing design (D), and sets a mass production setting value optimized for the processing shape of each processing unit (U) as a processing unit Each of (U) can be individually selected. Accordingly, the laser processing system may further improve the laser processing quality of the processing object D by laser processing the processing units U in an optimized manner according to the processing shape of the processing unit U, respectively.

On the other hand, it is preferable that the above-described selection of the set value for mass production is repeatedly performed. For example, in the selection of the set value for mass production, when a predetermined process time elapses from the time when the selection of the set value for mass production is previously performed, when the power of the laser processing device is turned on, etc. It can be repeated whenever this is satisfied. The data for the set value for mass production that is repeatedly selected as described above may be stored to be accumulated in the storage module 30 . Then, when selecting the set value for mass production, the number of test set values included in the processing recipe is reduced or the minimum set value, You can set the maximum setting value and the basic setting value precisely. Through this, the laser processing system 1 can further reduce the number of people and time required for the selection of the set value for mass production, and more accurately select the set value for mass production according to the process conditions, so that the laser of the object F is processed. The processing quality can be further improved.
