Example 1

The embodiment of the invention provides a printing method of PCB characters and labels, which is suitable for an application scene of printing characters on a PCB by using an ink-jet printing technology. As shown in fig. 1, the printing of PCB characters is to print characters, lines, color blocks, etc. (collectively referred to as character printing) on a PCB, and when printing, the printing process is completed by first analyzing and converting the data or file into print data by auxiliary software according to the Gerber format data or file made by Computer Aided Manufacturing (CAM) software before the printed circuit board is manufactured, positioning the precise pattern by CCD, and jet printing specific ink on the printed circuit board by inkjet technology.

Referring to fig. 2, the printing method of the PCB character and the label includes the following steps:

S1, acquiring a first file to be printed in a Gerber format;

s2, determining label printing information according to character printing information in the first file to be printed;

s3, integrating the label printing information into the first file to be printed to obtain a second file to be printed;

S4, converting the second file to be printed into a third file to be printed which can be identified by the printing equipment;

and S5, dynamically generating tag content information according to the third file to be printed and combining with the current task, and printing the characters and the tags on a printed circuit board.

Specifically, a first file to be printed in Gerber format is derived from an engineering file by Computer Aided Manufacturing (CAM) software before manufacturing a printed circuit board, such as Genesis2000, etc., and the first file to be printed is character printing related data including elements such as characters, color blocks or lines, etc., and character printing information such as character printing area, character size, color block printing area, color block size, line printing area, line size, etc., to be printed on the Printed Circuit Board (PCB). In order to avoid that the printed label covers the character, the color block or the line, the information of the printing area and the size of the elements such as the character, the color block, the line and the like on the PCB needs to be known according to the character printing information, and the label printing information including the label type, the label printing area, the placement direction, the size and the like is determined.

The determining label printing information according to the character printing information in the first file to be printed comprises the following steps:

Specifically, after the character printing information is obtained, the printing areas of the elements such as characters, lines, color blocks and the like on the PCB can be obtained according to the character printing information, so that blank areas of enough printed labels are determined and recorded as preset printing areas. The preset conditions may be determined according to practical situations, for example, the length and width of the preset printing area must be equal to or greater than the length and width of the label in the size.

In one embodiment, the user determines the printing area, the placement direction, the size and other label printing information of the labels on the PCB according to the character printing information, and in addition, the label types in the label printing information, such as two-dimensional codes, bar codes, characters, periodic codes or custom patterns and the like, can also be determined by the user, and the most suitable label types can also be selected according to the size and the like of the preset printing area on the PCB, for example, the finally determined label printing area is a smaller rectangular area on the PCB, the rectangular area is suitable for placing bar labels such as bar codes or serial numbers and is not suitable for placing square labels such as two-dimensional codes and the like, and the label types can be bar codes or serial numbers. In another embodiment, a preset printing area meeting preset conditions or most suitable for the preset printing area on the PCB can be automatically calculated according to character printing information obtained from the first file to be printed to serve as a label printing area, and then label placement direction, label size, label type and other label printing information are determined according to the label printing area, so that manual operation is avoided, and production efficiency is improved.

After the label printing information is determined, integrating the label printing information into a first file to be printed, namely integrating or presetting information such as label types, label printing areas, label placement directions, label sizes and the like in a Gerber file to be printed. Preferably, the integrating the label printing information into the first file to be printed to obtain the second file to be printed includes:

Acquiring the label printing information;

In one embodiment, integrating label printing information in a first file to be printed is achieved by using a script software tool, specifically, firstly, out_flag attributes corresponding to labels are set in CAM software such as a Genesis engineering file according to the acquired label printing information, and then the out_flag attributes are converted into D code instructions in a Gerber file by using the script software tool. For example, the dots and boxes for locating labels are defined in the out_flag attribute of the Genesis project file, and converted to corresponding dots and boxes in the D code using the scripting tool, wherein the dots in the D code are drawn using the r0 aperture. Notably, different tags should be distinguished using different Gerber instructions. Illustratively, in fig. 3, the serial number tags are defined using circles and boxes, and different contents are corresponding with different D codes. In fig. 3, when the D codes are 220, 221,222, 223, serial codes of which the tag placement positions (angles) are 0 °,90 °,180 °,270 ° are defined, respectively. When the serial number printing area or the printing area is drawn according to the definition, dots are drawn firstly, then frames are drawn, and the size of the frames is the size of the serial number label. In addition, it is noted that the dot coordinates have to coincide completely with one of the corners of the frame at the time of drawing, and the frame has to be a completely closed rectangular frame. In another example, as shown in fig. 4, two-dimensional code labels are defined using circle points and boxes, and again, both the dots and boxes use the out_flag attribute as the r0 aperture for the corresponding D code. Different D codes correspond to different content. In fig. 4, when the D-codes are 350, 351,352, 353, two-dimensional codes having a label placement position (angle) of 0 °,90 °,180 °,270 ° are defined, respectively.

The addition of serial codes, two-dimensional codes and the like on software can be achieved by setting D codes and corresponding label positions or directions (angles) in engineering data such as ref files, specific additional information is specified by special D codes in the ref files so as to assist in presetting a printing area of labels in Gerber files, and the definition of the D codes is shown in the following table:

D code	Corresponding content
		233	Locating point
210,211,212,213	Period code (0 degree, 90 degree, 180 degree, 270 degree)
		220，221,222,223	Sequence code (0, 90, 180, 270)
310,311,312,313	Bar code (0, 90, 180, 270)
		350,351,352,353	QR two-dimensional code (0, 90, 180, 270.)
360,361,362,363	Digital two-dimensional code (0 degree, 90 degree, 180 degree, 270 degree)

In other embodiments, the D code and the placement position (angle) may be set according to the actual situation, for example, the placement angle of the stamp (two-dimensional code) is set to 60 ° when D is set to 354, and so on. The D codes and their definitions listed in the above table and the above examples are only for illustration and are not intended to limit the scope of the present invention.

After setting the D code in the ref file, the CAM software imports the drawing information of the label from the ref file and integrates the label printing information such as the label position, the label placement direction, the label size and the like into the first file to be printed in the Gerber format to be printed, wherein the first file to be printed is the file in the Gerber format, only the character printing information is contained before the first file to be printed, the character printing information and the label printing information are integrated after importing the label printing information, and the file in the Gerber format is called a second file to be printed.

Typically, a printed circuit board (PNL) includes a plurality of tiles (SET), and one tile (SET) includes a plurality of unit boards (PCS). In one embodiment, as shown in fig. 5, a layout is schematically shown that includes a plurality of cell plates. At this time, the label printing information can be set for one unit board, and then the set label printing information is copied to other unit boards in the same jigsaw, or the unit boards of the same type jigsaw, so that the quick integration of the label printing information of a plurality of unit boards is realized.

When characters and labels are printed on the PCB, the second file to be printed in the Gerber format needs to be converted into a file format which can be identified by the printing equipment and recorded as a third file to be printed, the third file to be printed records character printing information and label printing information which can be identified by the printing equipment and is printed on the PCB, and the printing equipment prints the PCB characters and labels according to the character printing information and the label printing information in the third file to be printed.

Acquiring the information of a printed circuit board to be printed currently;

In one embodiment, the second to-be-printed file only has information such as a label printing area, a label placement direction and a label size, and the like, and the third to-be-printed file which can be converted into the information such as the label printing area, the label placement direction and the label size, and the like, which can be identified by the printing device, is also only information such as the label printing area, the label placement direction and the label size, and the label content information is dynamically generated according to the current printing task, for example, the specific content of the label can be set by the printing system according to the information of the printed circuit board to be printed currently or external input settings, and the like. The method includes setting printed circuit board (PNL) information including PNL identification, SET identification, PCS identification and the like for PCB production board (PNL) information with a plurality of unit boards (PCS) or panels (SET), if different label content is to be printed for each unit board, such as different two-dimensional code information is printed for each unit board, at this time, the printing area, placement direction and size of the two-dimensional code are the same in each unit board, but the content of the two-dimensional code is dynamically produced when printing, such as printing a first two-dimensional code on a first unit board, printing a second two-dimensional code … … on a second unit board, and characterizing different information of the first two-dimensional code and the second two-dimensional code, at this time, the printing system knows which PCB production board, which panel and which unit board are currently printed according to the PNL identification, SET identification, PCS identification and the like, and generates corresponding two-dimensional codes, and prints the two-dimensional codes onto the corresponding unit boards according to the label printing area, placement direction and the like in the label printing information. In another example, the same label content may be printed by multiple unit boards in one board, but the label content of each of the multiple boards is different, at this time, the printing system knows which PCB production board is currently printed, which board is currently printed, and generates corresponding label content according to the printed circuit board information such as PNL identifier, SET identifier, PCS identifier, etc., generates different label content information for each board, prints the same first label content for each unit board in the first board, prints the same second label content for each unit board in the second board, etc.

In another embodiment, the second file to be printed may further have fixed tag content information (i.e. content of fixed two-dimensional code, bar code, text, periodic code) built therein, and the third file to be printed which can be identified by the printing device is converted into fixed tag content information, and the printing device prints corresponding characters and tags on each cell board according to the character printing information and the tag printing information in the third file to be printed. In addition, the number of the printed labels on the PCB can be determined according to the actual situation, if a plurality of labels are required to be printed, the printed information of the labels is integrated into the file to be printed in the Gerber format, and the file to be printed is converted into the file format recognizable by the printing equipment for printing. As shown in fig. 6, a schematic diagram of printing a plurality of labels on one unit board is shown.

In summary, according to the method for printing the PCB characters and the labels provided by the embodiments of the present invention, the label printing information is determined according to the character printing information, and the label printing information is integrated into the Gerber file to be printed, and the printing device dynamically generates the label content information according to the Gerber file integrated with the character printing information and the label printing information and combines with the current task, and prints the characters and the labels onto the printed circuit board. Compared with the existing method for attaching labels printed in advance on each PCB finished product by using a labeling machine, the printing method for the PCB characters and the labels solves the problem that the labels cover PCB circuits or characters, saves cost and improves the printing effect and efficiency of the PBC labels.
