[0024] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0025] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be another element centered thereon. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be another element centered thereon at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] See also Figure 1 The present application embodiment provides a method for generating PCBA packaging information, comprising the following steps: Step S10: Read the Gerber file to be parsed; Step S20: parsing the Gerber file and displaying the product graphics obtained by parsing in the graphics display area 3; Step S30: drawing an initial packaging pattern on the product graphic in the graphic display area 3; Step S40: adjusting the initial packaging pattern to obtain a target packaging pattern; Step S50: setting the spraying thickness of different parts of the target packaging pattern to obtain a printing project; Step S60: saving and exporting the printing project.

[0028] The method for generating PCBA packaging information provided in this embodiment can not only read and parse the Gerber file, and display the product graphics obtained by the analysis in the graphics display area 3, but also directly draw the initial packaging pattern on the product graphics in the graphics display area 3, and can adjust the initial packaging pattern to the target packaging pattern, and then set the spraying thickness of different parts of the target packaging pattern, so as to obtain the printing project (the printing project is the required PCBA packaging information), so that the packaging device can package the PCBA board according to the printing project. The method for generating PCBA packaging information can simplify the production process of the printing project, and directly draw the packaging pattern on the product graphics in the graphics display area 3 with high drawing accuracy, so as to improve the packaging accuracy of the PCBA board.

[0029] In this embodiment, for step S10, the Gerber file to be parsed can be selected by clicking the "Read" button. The Gerber file contains multiple layers, each layer corresponds to a specific part in the PCB design, and common layers include circuit layer, solder mask layer, silk screen layer, drilling layer, etc. The circuit layer is the skeleton of the PCB and carries the transmission path of the current; the solder mask layer covers the area that does not need to be soldered to prevent short circuits; the silk screen layer marks the position number and parameter information of the component; the drilling layer indicates the location and specifications of the drilling, which is used for positioning and processing during the manufacturing process. The information of each layer of the Gerber file can be displayed in the loading area 8. The information of each layer may include the layer name and color.

[0030] In step S20, the Gerber file can be parsed by clicking a "Start" button. The "Start" button can be set in the loading area 8.

[0031] In this embodiment, in the step of drawing the initial packaging pattern (i.e., step S30), the drawing stroke has a first state and a second state. When the drawing stroke is in the first state, the drawn primitive is in a solid state. When the drawing stroke is in the second state, the drawn primitive is in a hollow state. By switching the first state and the second state of the drawing stroke, the glue spraying line or the glue spraying filling part can be conveniently drawn.

[0032] Specifically, in step S30, a straight line, rectangle, circle, ellipse or polygonal brush stroke can be selected for drawing. When a straight line brush stroke is selected for drawing, the drawing brush stroke is always in the first state, that is, drawing a solid straight line.

[0033] When a rectangle, circle, ellipse or polygonal stroke is selected for drawing, the drawing stroke defaults to the second state, that is, the default drawing of a rectangle, circle, ellipse or polygon is first in a hollow state, and a hollow rectangle, circle, ellipse or polygon will be drawn (that is, the edges of the rectangle, circle, ellipse or polygon will be drawn). By pressing the switch button 9, the second state is switched to the first state, so that a solid rectangle, circle, ellipse or polygon can be drawn. The switch button 9 can be a "fill" button.

[0034] In this embodiment, the step of adjusting the initial packaging pattern (ie, step S40) includes: Step S401: Selecting a first pattern to be adjusted in the initial packaging pattern, and a rectangular dotted frame appears outside the first pattern to be adjusted; Step S402: drag any side of the rectangular dotted frame to adjust the position of the first graphic to be adjusted.

[0035] In step S401, the side of the rectangular dotted frame is tangent to the side of the first figure to be adjusted. In step S402, the position of the entire first figure to be adjusted can be adjusted. In addition, after step S401, the first figure to be adjusted can be deleted by pressing the "Delete" button.

[0036] Further, after step S401, the lower right corner of the dotted rectangle frame can be selected and moved to adjust the size of the first graphic to be adjusted. When the mouse moves to the lower right corner of the dotted rectangle frame, a double arrow will appear, and by pressing and moving, the size of the first graphic to be adjusted can be adjusted to a desired size.

[0037] In one embodiment, the step of adjusting the initial packaging pattern (ie, step S40) includes: Step S403: selecting a second pattern to be adjusted in the initial packaging pattern; Step S404: setting the array distance, array direction and array quantity so that the second pattern to be adjusted completes the array.

[0038] Through step S403 and step S404, the second graphics to be adjusted can be arrayed according to the required distance, direction and quantity, thereby improving the drawing efficiency. Step S404 can be set by pressing the array button 6.

[0039] In another embodiment, the step of drawing the initial packaging pattern (step S30) includes: drawing the initial packaging pattern in the spraying area at the upper left corner of the product graphic in the graphic display area 3. Correspondingly, the step of adjusting the initial packaging pattern (step S40) includes: Step S405: measuring the center distance of the product graphics in the horizontal and vertical directions; Step S406: Array the spraying area of ​​the entire product pattern according to the initial packaging pattern to obtain the target packaging pattern.

[0040] The array method of step S405 and step S406 is suitable for PCBA boards with neat and regular arrangement of components, and can quickly realize array. The horizontal direction and the vertical direction in step S405 correspond to the length direction and the width direction of the PCBA board.

[0041] See also Figure 2 The embodiment of the present invention also provides a system for generating PCBA packaging information, including: a reading module 1, a parsing module 2, a graphic display area 3, a drawing module 4, an adjustment module 5, a setting module and a saving module 7.

[0042] Among them, the reading module 1 is used to read the Gerber file to be parsed. The parsing module 2 is used to parse the Gerber file. The graphic display area 3 is used to display the product graphics parsed by the parsing module 2. The drawing module 4 is used to draw the initial packaging pattern on the product graphics. The adjustment module 5 is used to adjust the initial packaging pattern to obtain the target packaging pattern. The setting module is used to set the spraying thickness of different parts of the target packaging pattern to obtain a printing project. The saving module 7 is used to save and export the printing project.

[0043] The system for generating PCBA packaging information provided in this embodiment can not only read and parse the Gerber file through the reading module 1 and the parsing module 2, and display the product graphics obtained by parsing in the graphics display area 3, but also directly draw the initial packaging pattern on the product graphics in the graphics display area 3 through the drawing module 4, and adjust the initial packaging pattern to the target packaging pattern through the adjustment module 5, and then set the spraying thickness of different parts of the target packaging pattern through the setting module, so as to obtain the printing project, and save and export the printing project through the saving module 7, so that the packaging device can package the PCBA board according to the printing project. The system for generating PCBA packaging information can simplify the production process of the printing project, and directly draw the packaging pattern on the product graphics in the graphics display area 3 with high drawing accuracy, so as to improve the packaging accuracy of the PCBA board.

[0044] In this embodiment, the graphics primitives drawn in the current graphics display area 3 can be saved as BMP monochrome images through the saving module 7. The drawing module 4 may include a straight line button, a rectangle button, a circle button, an ellipse button, and a polygon button. Press the straight line button, and press the "shift" key when drawing a line segment to ensure that the drawn line segment is vertical or horizontal. Press the rectangle button, and press the "shift" key when drawing a rectangle to ensure that a square is drawn. Press the circle button, and hold down Shift during the drawing process to draw a perfect circle graphics primitive. Press the polygon button, click the left mouse button at the desired position to generate the first point of the polygon, and click the left button for the remaining corner points as well. Click the right mouse button at the end, and the graphics primitive automatically forms a closed loop. If the graphics primitive does not need to form a closed loop, you can press the computer Enter key to interrupt at the point where you need to stop.

[0045] In addition, the system can also set a line width button to control the pixel width of the drawn pattern line. The default width is 3 pixels, and special application scenarios can be determined according to specific circumstances. The system can also set an eraser button to implement the layer erasing function. The system can also set a screen ruler button to display or hide the screen ruler of the graphic display area 3, which is hidden by default.
