In the present embodiment, the characters of the circuit board are designed by engineers, usually by CAM (Computer Aided Manufacturing) software, and are output to obtain a picture file in a bitmap format. After a bitmap file is obtained, generating at least one placing frame for placing the variable dynamic two-dimensional code in the bitmap, wherein the placing frame is rectangular; generating a pad with a flash attribute at any corner of the generated placing frame, and identifying the angle of the two-dimensional code placing frame through the pad, for example, when the pad is positioned at the lower left corner of the two-dimensional code placing frame, the two-dimensional code placing frame is 0 degree; when the bonding pad is positioned at the upper left corner of the two-dimensional code placing frame, the two-dimensional code placing frame is at-90 degrees; when the bonding pad is positioned at the upper right corner of the two-dimensional code placing frame, the two-dimensional code placing frame is 270 degrees; when the bonding pad is positioned at the lower right corner of the two-dimensional code placing frame, the two-dimensional code placing frame is 180 degrees. It can be understood that the bonding pad only plays a role in marking, and no matter which corner point of the two-dimensional code placing frame is generated, the two-dimensional code placing frame is not changed and is only used for marking the placing angle of the two-dimensional code placing frame.
In this embodiment, the size and position information of the two-dimensional code placement frame are output, where the size information includes a line width, a length, and a width, and the position information at least includes coordinates of a start point and an end point of the two-dimensional code placement frame, where the start point refers to an angular point where the pad is located, and the end point is an opposite angle corresponding to the start point.
In this embodiment, the two-dimensional code is obtained by calling a two-dimensional code generator; and after the two-dimensional code generator generates a two-dimensional code picture, attaching the two-dimensional code picture to a two-dimensional code placing frame to obtain an image for jet printing. And then, transmitting the image for jet printing to jet printing equipment, and executing jet printing action by the jet printing equipment to obtain a jet printing pattern.

The method provided by the invention realizes the integration of fixed characters and variable characters and one-time jet printing, improves the production efficiency, and can effectively solve the problems of ink color difference and low overprinting precision caused by jet printing on different equipment; as shown in fig. 2 and 3, the images before and after the application of the present invention are shown.
As a preferred solution of the embodiment of the present invention, the generating a variable dynamic two-dimensional code placement frame in the obtained bitmap file of the circuit board identification character includes:
determining a placement area in the obtained bitmap file of the circuit board identification characters;
determining a starting point and an end point of a variable dynamic two-dimensional code placing frame in a placing area;
generating a variable dynamic two-dimensional code placement frame according to the determined starting point and the determined end point;
endowing different line widths for different variable dynamic two-dimensional code placing frames;
setting a bonding pad with Flash attributes at the starting point of the variable dynamic two-dimensional code placing frame to identify the angle of the variable dynamic two-dimensional code placing frame;
and deriving the linear code number, the coordinates of the starting point and the ending point and the angle of the variable dynamic two-dimensional code placing frame.
In this embodiment, by determining the placement area, the variable dynamic two-dimensional code can be prevented from being attached to the bitmap and then overlapping with the original circuit board identification characters, so that the layout of the information is clear and complete.
In this embodiment, the start point and the end point of the variable dynamic two-dimensional code placement frame are both located in the placement area.
In this embodiment, when the variable dynamic two-dimensional code placement frame may be limited to a rectangle in the horizontal or vertical direction, the variable dynamic two-dimensional code placement frame may be uniquely determined by the start point and the end point at this time.
In the embodiment, different rectangles are distinguished by endowing different variable dynamic two-dimensional code placing frames with different line widths
As a preferable solution of the embodiment of the present invention, the size of the two-dimensional code placement frame includes a line width, a frame length, a frame width, and a frame angle.
In this embodiment, the two-dimensional code placement frame of a unique shape can be defined by the size of the two-dimensional code placement frame.
As a preferable solution of the embodiment of the present invention, the variable dynamic two-dimensional code includes a dynamic serial number, the dynamic serial number is equal to the number of the variable information placing frames having the first line width, and the number hopping rule is set to increase with the number of the variable information placing frames having the first line width;
the serial number is matched with the number of the variable information placing frames with the second line width, and the skip number rule is set to be that the serial number is added with 1 after the number of the variable information placing frames with the second line width reaches one batch quantity;
the cycle matches the system time, with the skip number rule set to 24 per day of the week: 00 cycles plus 1.
In the embodiment, the dynamically generated variable information can be automatically changed according to the product batch, the production time, the production quantity and the like through the rules, manual operation is not needed, information errors caused by misoperation are avoided, meanwhile, personnel are not needed to track the change of the information, and automatic adjustment of the information is realized.
As a preferred solution of the embodiment of the present invention, the generating a variable dynamic two-dimensional code placement frame in the obtained bitmap file of the circuit board identification character includes:
identifying a placement area of the obtained bitmap file of the circuit board identification characters;

determining the central point of the variable dynamic two-dimensional code placing frame in the determined maximum continuous area;
and generating the variable dynamic two-dimensional code placing frame according to the determined central point of the variable dynamic two-dimensional code placing frame and the preset size of the placing frame.
In this embodiment, the placement area is not overlapped with the original circuit board identification characters, i.e., the blank area of the pattern. In this embodiment, because the circuit board identification character is divided, the placement area is usually discontinuous, and the placement area with the largest area is found through the algorithm, so that the placement of the variable dynamic two-dimensional code can be facilitated, and the size of the variable dynamic two-dimensional code is not limited too much (the two-dimensional code is identified by code scanning equipment when in use, so that the two-dimensional code cannot be too small to cause identification difficulty).
In this embodiment, the size of the movable dynamic two-dimensional code can be set when the movable dynamic two-dimensional code is generated, so as to be matched with the variable dynamic two-dimensional code placement frame.
As a preferable solution of the embodiment of the present invention, the identifying the obtained placement area of the bitmap file of the circuit board identification character includes:
selecting an identification window, and for any pixel, when the pixel is overlapped with the central pixel of the identification window, if the pixel is the foreground color of the bitmap, marking all pixels covered by the identification window as excluded pixels;
moving the recognition window to traverse all pixels of the bitmap, determining all excluded pixels;
and determining a placement area in the bitmap file of the circuit board identification character according to the determined excluded pixels.
In this embodiment, optionally, the recognition window may be selected as n × n pixels, that is, n pixels wide and n pixels long, where n is an odd number, and (n-1)/2 is a distance between the set placement area and the circuit board identification character. In this embodiment, through the above steps, the excluded pixels can be quickly found, and the found excluded pixels are excluded from the placement area.
As a preferable aspect of the embodiment of the present invention, the determining the largest continuous area in the identified placement areas includes:
randomly selecting a background pixel in the identified placing area, and determining all adjacent pixels to obtain an adjacent area by taking the selected background pixel as a starting point according to whether a common edge exists or not;
repeating the previous step until all background pixels are divided into one adjacent region to obtain at least one adjacent region;
determining the diagonal length and the included angle of the two-dimension code placement frame according to the size of the given two-dimension code placement frame;
generating and moving a diagonal line of the two-dimensional code placement frame in each adjacent area;
when the diagonal line of the two-dimensional code placement frame is completely positioned in the adjacent area, the two ends of each diagonal line are extended in equal proportion, and the product of the lengths of the two diagonal lines is calculated;
and for each adjacent area, taking the maximum value of the obtained diagonal length product as an evaluation value, and determining the maximum adjacent area according to the evaluation value.
In this embodiment, a neighboring region is obtained by determining all neighboring pixels according to whether the pixels have a common edge, and it can be understood that, for example, for sequentially neighboring pixels 1, 2, and 3, pixel 1 and pixel 2 have a common edge, and pixel 2 and pixel 3 also have a common edge, then pixels 1, 2, and 3 form a small neighboring region.
In this embodiment, by generating and moving the diagonal line of the two-dimensional code placement frame and by determining whether the diagonal line is completely located in the adjacent area, it can be determined whether the adjacent area can accommodate the two-dimensional code placement frame. When the two-dimensional code placing frame is completely positioned in the adjacent area, the length of the diagonal line of the two-dimensional code placing frame is extended in an equal proportion until any one of four corner points of the two diagonal lines is intersected with the edge of the adjacent area, the product of the lengths of the diagonal lines is used as an evaluation value, and the adjacent area with the largest evaluation value is selected to place the two-dimensional code placing frame.
