The oscillator 11 oscillates laser light in response to a control signal from the oscillator control section 125 . Oscillator 11 includes a laser light source. Although the type of laser light source is not particularly limited, for example, a fiber laser can be used as the laser light source. The laser light source may be a solid-state laser such as a YAG laser, or a gas laser such as a CO2 laser. The laser light from the laser light source may be pulsed light or continuous (CW) light.

The scanning mechanism 21 scans the laser light oscillated by the oscillator 11. The scanning mechanism 21 includes a mirror 22 and a driver 23 that drives the mirror 22 . A laser beam oscillated by the oscillator 11 is reflected by the mirror 22 and irradiated onto the surface of the workpiece 1 (see FIG. 1) placed on the stage 301 (see FIG. 1).

The drive unit 23 drives the mirror 22 in response to a control signal from the marking head control unit 126. As a result, the workpiece 1 is scanned so as to reciprocate with the laser beam. The scanning direction of the laser light by the scanning mechanism 21 may be one-dimensional, two-dimensional, or both.

The first communication unit 501 also transmits the shape data of the workpiece 1 generated by the first generation unit 503 to the laser marker 100 .

The imaging unit 502 images the workpiece 1 and transmits the captured image to the first generation unit 503 in response to the first communication unit 501 receiving the instruction to capture the workpiece image.

Upon receiving the captured image from the imaging unit 502, the first generating unit 503 generates shape data indicating the shape of the workpiece 1 based on the captured image. The shape data indicating the shape of the work 1 may be data of the outline of the work 1 or data of the entire area occupied by the work 1 in the captured image.

The contour data of Work 1 is vector data containing the coordinates of the start point and the coordinates of the end point for each line segment. The first generation unit 503 generates vector data by performing edge processing, thinning processing, line segment approximation processing, and the like on the captured image received from the imaging unit 502 .

The data of the entire area occupied by the workpiece 1 in the captured image is raster data such as jpg data and bmp data. The first generating unit 503 performs area division processing (segmentation) on the captured image received from the imaging unit 502, and divides a specific area into a specific color or density, and other areas into a different color or density. Generates images filled with other densities. As the method of segmentation, for example, a binarization method using a density threshold, a method of extracting a specific color subspace in a color space such as HSV, or the like is adopted.

The first generation unit 503 transmits the generated shape data of the workpiece 1 to the first communication unit 501 .

The second communication unit 121 communicates with the image sensor 500. The second communication unit 121 transmits a work image capture instruction to the image sensor 500 in response to the second generation unit 122 accepting the work image capture instruction. The second communication unit 121 also receives shape data of the work 1 from the image sensor 500 and transmits the received shape data of the work 1 to the second generation unit 122 .

When the icon is operated by the user, the input unit 201 notifies the laser marker 100 that the icon has been pressed. The second generating unit 122 receives the notification from the input unit 201 and provides the setting device 200 with the input screen 700 . Thereby, the input screen 700 is displayed on the display of the setting device 200 . The second generation unit 122 receives information input according to the information on the input screen 700 and generates print data. The second generating unit 122 may receive information directly input to the input screen 700 according to the information on the input screen 700, or may receive information input from various input devices according to the information on the input screen 700. may be accepted. The input device may include the input unit 201, or may include other devices.

Specifically, the second generation unit 122 accepts the print block P (see FIGS. 5 and 6) input according to the information on the input screen 700 . The printing block P is a unit in which line patterns (eg, line width, type of dashed line, etc.) and parameters related to laser beam control (eg, laser beam repetition frequency, pulse width, etc.) can be set. The print block P includes at least one of characters, numbers, symbols, graphics, barcodes, two-dimensional codes, and images (bmp data, jpg data, etc.). A figure includes at least one of a fixed point, a straight line, a rectangle, a circle, and an arc. The print block P is rectangular, for example. When the print block P contains characters, the second generation unit 122 arranges the characters so that the direction of setting the characters and one side of the print block P are parallel. The same applies when the print block P contains numbers and symbols. The print data consists of one or more print blocks.

Also, the second generation unit 122 accepts an instruction to import a work image. As an example, the display of the setting device 200 displays an icon for receiving an instruction to capture a work image. When the icon is operated by the user, the input unit 201 notifies the laser marker 100 that the icon has been pressed. Upon receiving the notification from the input unit 201 , the second generation unit 122 instructs the second communication unit 121 to transmit an instruction to capture the work image to the image sensor 500 .

Further, when receiving a transmission instruction from setting unit 124 , second generation unit 122 transmits the stored print data to setting unit 124 .

The notification unit 123 notifies the error. Specifically, when the work image I shows the outline of the work, the notification unit 123 detects that at least part of the print block received by the second generation unit 122 is outside the area surrounded by the work image I. Signal an error depending on the location. On the other hand, when the work image I shows the entire area occupied by the work 1 in the captured image, the notification unit 123 determines that at least a part of the print block received by the second generation unit 122 is the work image I. Signal an error in response to being located outside.

The setting unit 124 accepts instructions for setting processing conditions. As an example, the display of the setting device 200 displays icons for receiving processing condition setting instructions. When the icon is operated by the user, the input unit 201 notifies the laser marker 100 that the icon has been pressed.

The setting unit 124 receives notification from the input unit 201 and sets processing conditions. Also, the setting unit 124 receives the notification from the input unit 201 and acquires print data from the second generation unit 122 . The setting unit 124 transmits the set processing conditions to the oscillator control unit 125 and the marking head control unit 126 together with the print data acquired from the second generation unit 122 .

The oscillator control unit 125 controls the operation of the oscillator 11 based on the print data and processing conditions received from the setting unit 124.

The marking head control unit 126 controls the operation of the drive unit 23 based on the print data and processing conditions received from the setting unit 124.

The processes of step S303 and step S306 are implemented by the first communication unit 501 . The process of step S304 is implemented by the imaging unit 502 . The process of step S<b>305 is implemented by the first generation unit 503 .

At step S301, the laser marker 100 accepts an instruction to capture a workpiece image.

In step S<b>302 , the laser marker 100 transmits an instruction to capture the workpiece image to the image sensor 500 .

In step S<b>303 , the image sensor 500 receives an instruction to capture the workpiece image from the laser marker 100 .

In step S304, the image sensor 500 images the workpiece 1.

At step S306, the image sensor 500 transmits the shape data of the workpiece 1 generated at step S305 to the laser marker 100.

In step S<b>307 , the laser marker 100 receives shape data of the work 1 from the image sensor 500 .

In step S308, the laser marker 100 causes the workpiece image I indicated by the shape data received in step S307 to be superimposed on the input screen 700 and displayed.

After step S308, the laser marker 100 ends the series of processes shown in FIG.

An input screen according to the embodiment will be described with reference to FIGS. 1, 2, and 4 to 6. FIG. FIG. 4 is a diagram showing an example of an input screen when loading of a workpiece image is completed.

With reference to FIGS. 1, 2, and 4, the input screen 700 is displayed on the display of the setting device 200. FIG. The input screen 700 includes a field 701 for inputting characters, figures, etc. to be printed by the laser marker 100 . The user uses the input unit 201 of the setting device 200 to draw characters, figures, and the like to be printed by the laser marker 100 in the field 701 .

The area specified by column 701 corresponds to the printable range of laser marker 100 . The position and size corresponding to the field of view of the imaging unit 502 are defined in the field 701 by preliminary calibration. When the user gives an instruction to capture the work image, a series of processes shown in FIG. 3 are executed, and the work image I coordinate-transformed according to the regulations is superimposed on the column 701 and displayed. A work image I in FIG. 4 shows the outline of the work 1 . The column 701 can be displayed enlarged or reduced according to icon operation or the like on the input screen 700 .

The user can set the print data in the laser marker 100 by arranging the print block within the area surrounded by the work image I. When the print block is placed, the input unit 201 notifies the laser marker 100 of the position where the print block is placed. The second generation unit 122 receives the notification from the input unit 201 and generates print data.

The input screen 700 further includes an icon 702. An icon 702 accepts an instruction to generate print data for background processing. The surface treatment is a process of leveling the surface of the workpiece 1 by irradiating it with a laser beam, which is performed prior to printing characters, figures, and the like.

When the icon 702 is operated by the user, the input unit 201 notifies the laser marker 100 that the icon 702 has been pressed. The second generation unit 122 receives the notification from the input unit 201 and generates print data for printing the area surrounded by the work image I. FIG. As a result, the print data in which the area surrounded by the work image I is the object of laser processing, that is, the print data for base treatment is generated.

As a result, the user does not need to input the size, shape, etc. of the workpiece 1 when the laser marker 100 generates print data for base treatment. Therefore, the user's burden of setting print data is reduced.

When the work image I shows the entire area occupied by the work 1 in the captured image, the user arranges the print block in the area where the work image I is displayed, thereby transferring the print data to the laser marker. Can be set to 100. Further, in this case, in response to the user's operation of the icon 702, the second generation unit 122 generates print data for printing the area where the workpiece image I is displayed.

FIG. 5 is a diagram showing an example of an input screen when print blocks are arranged after the work image has been captured. 1, 2, and 5, a work image I and a print block P are displayed in column 701. FIG. A work image I in FIG. 5 shows the outline of the work 1 .

The input screen 700 further includes an icon 703. Icon 703 accepts an instruction to enable notification. When the icon 703 is operated by the user, the input unit 201 notifies the laser marker 100 that the icon 703 has been pressed. The notification unit 123 receives the notification from the input unit 201 and determines whether or not at least part of the print block P is positioned outside the area surrounded by the work image I. The notification unit 123 notifies an error in response to determining that at least part of the print block P is positioned outside the area surrounded by the work image I. FIG. Thereby, the user can recognize that the position of the print block P needs to be changed.

Note that when the workpiece image I shows the entire area occupied by the workpiece 1 in the captured image, the notification unit 123 receives a notification from the input unit 201 indicating that the icon 703 has been pressed. , whether at least a part of the print block P is positioned outside the work image I or not. The notification unit 123 notifies an error when at least part of the print block P is positioned outside the work image I. FIG.

FIG. 6 is a diagram showing another example of the input screen when the print blocks are arranged after the work image has been captured. A workpiece image I in FIG. 6 shows the outline of the workpiece 1 .

1, 2, and 6, the input screen 700 further includes an icon 704. An icon 704 accepts an instruction to automatically adjust the rotation angle of the print block P. FIG. The function of automatic rotation angle adjustment is effective when the contour of the workpiece 1 has a linear portion and the print block includes at least one of letters, numerals, symbols, bar codes, and two-dimensional codes. A contour having a straight portion is, for example, a rectangle, a semicircle, or the like. When the icon 704 is operated by the user, the input unit 201 notifies the laser marker 100 that the icon 704 has been pressed. The second generating unit 122 receives the notification from the input unit 201, identifies the straight line portion of the contour of the work 1, and identifies one side of the received print block P and the straight line portion of the work 1 identified by the work image I. provides candidates for the inclination of the print block P so that the P is parallel or perpendicular. As an example, the second generating unit 122 places the received print block P on the input screen 700 so that one side of the received print block P is parallel or perpendicular to the straight line portion of the workpiece 1 specified by the workpiece image I. display.

As a result, as shown in FIG. 6, since the inclinations of the print block P and the work image I are the same, the text composition direction and the straight line portion of the work 1 specified by the work image I become parallel. As an example, the print block P is arranged such that the side e1 of the print block P and the straight line portion E1 of the work 1 specified by the work image I are parallel. The print block P is arranged so that the side e1 of the print block P and the straight line portion E2 of the work 1 specified by the work image I are perpendicular to each other. As a result, the character composition direction and the straight line portions E2 and E4 of the workpiece 1 specified by the workpiece image I become parallel.

Note that even when the work image I shows the entire area occupied by the work 1 in the captured image, the second generation unit 122 receives from the input unit 201 the notification indicating that the icon 704 has been pressed. Accordingly, a candidate for the inclination of the print block P is provided so that one side of the received print block P and the linear portion of the work 1 specified by the work image I are parallel or perpendicular. As an example, the second generating unit 122 places the received print block P on the input screen 700 so that one side of the received print block P is parallel or perpendicular to the straight line portion of the workpiece 1 specified by the workpiece image I. display.

The second generating unit 122 generates print data corresponding to the print block P displayed on the input screen 700 in response to the operation of the enter button (or the save button) displayed on the input screen 700, Save the generated print data.

As described above, according to the above-described embodiment, by arranging the print block P at a desired position within the work image I, the laser marker 100 can print characters, figures, etc. at a desired position within the work 1. can. Therefore, the user's burden of setting print data is reduced.

Note that the laser marker 100 does not have to include the notification unit 123 .

Also, the laser marker 100 may not be configured to be able to receive an instruction to generate print data for printing the area surrounded by the workpiece image I.

Also, the laser marker 100 may not be configured to be able to receive an instruction to generate print data for printing the area where the workpiece image I is displayed.

Also, the laser marker 100 may not be configured to be able to receive an automatic adjustment instruction for the rotation angle of the print block P.

Also, the second generation unit 122 may refer to graphic data (CAD data, bmp file, etc.) created by an external device as the print block P. In that case, link information such as the file name of the file recording the graphic data is added to the print data.

Also, the print block P may be provided with a print valid/invalid flag. When the print block P is given a valid flag, the print block P is displayed on the input screen 700 and also reflected in the print data. On the other hand, when the print block P is given an invalid flag, the print block P is displayed on the input screen 700, but is not reflected in the print data.

Also, the raster data generation process may be performed by, for example, the second generation unit 122 of the laser marker 100 instead of the first generation unit 503 . In that case, an image captured by the imaging unit 502 is transmitted from the image sensor 500 to the laser marker 100 .

Further, when the shape data received by the second communication unit 121 is raster data, the second generation unit 122 performs binarization processing, and inputs the work image I indicated by the data after the binarization processing. It may be displayed superimposed on the screen 700 . As a result, the processing time for enlarging or reducing the work image I on the input screen 700 can be shortened.

Further, each time the icon 702 is operated, a state in which print data for base processing is generated and a state in which print data for base processing is not generated may be switched.

Further, each time the icon 703 is operated, the state in which the error notification is performed and the state in which the error notification is not performed may be switched.

Further, each time the icon 704 is operated, a state in which the rotation angle of the print block P is automatically adjusted and a state in which the rotation angle of the print block P is not automatically adjusted may be switched. .

Also, as another embodiment, the laser print data generator shown in FIG. 7 may be adopted. FIG. 7 is a diagram for explaining a laser print data generator. A laser print data generator 150 generates print data for the laser marker 100A.
