However, these gaps are difficult to measure accurately due to their small size, and the accuracy is also compromised during the file format conversion process, resulting in low marking accuracy. Furthermore, the large number of parameters that need to be marked makes the marking process cumbersome. Summary of the Invention

[0064] Example 1

[0065] Figure 1This is a flow chart of a PCB automatic marking method provided by the first embodiment of the present invention. This embodiment can be applied to a PCB automatic marking device. The method can be executed by the PCB automatic marking device. The device can be implemented by software and / or hardware and can generally be integrated into a computer device. The computer device can include a terminal device, a server device, or a single-chip device. The embodiment of the present invention does not limit the specific device type of the computer device. Accordingly, Figure 1 As shown, the method includes the following operations:

[0066] S110. Select the annotation type of the annotation object.

[0067] In one embodiment, before automatic annotation is performed, it is necessary to generate an annotation algorithm for the corresponding annotation type in advance. The specific process is as follows: import the Gerber project file corresponding to the annotation object; receive the user's selection of the annotation type based on the Gerber project file in the menu interface of the corresponding program; obtain all the annotation elements of the annotation object; confirm the target annotation type that can be annotated based on the annotation elements; and generate the corresponding annotation algorithm based on the target annotation type. In this embodiment, the annotation object refers to one or more board layers corresponding to the Gerber file. Generally, the annotation objects can be divided into single boards and panels, such as Figure 2 The single board shown includes only one board layer 201, such as Figure 3 The illustrated panel comprises at least two or more board layers 301. Each board layer 301 in the panel is also called a single piece. Figure 3 Includes 9 singles.

[0068] In one embodiment, the annotation types include one or more of individual dimensions, panel dimensions, panel quantity, process edge width, board edge spacing, panel spacing, tool hole coordinates, photoelectric coordinates, cutting lines, and PCB board orientation. In this embodiment, individual dimensions refer to the outline annotation data of a board layer, i.e., the dimensions of a panelized layer; panel dimensions refer to the overall dimensions of the multiple individual components after panelization; process edge width refers to the distance from the panel to the gong tape outline; and panel spacing refers to the distance between individual dimensions.

[0069] S120 , confirming the elements to be annotated of the annotation object according to the annotation type and calculating the annotation data.

[0070] In one embodiment, if the annotation type is a single size or a panel size, the following steps are included in determining the elements to be annotated of the annotation object according to the annotation type and calculating the annotation data based on the elements to be annotated.

[0074] S1214. Generate a horizontal annotation auxiliary line at the preset element width annotation position, for example Figure 4 The auxiliary line L2 in the annotation is used as the two anchor points of the element outline width according to the two points A' and B' of the horizontal intercepts of the two vertical lines AD and BC of the element outline on the annotation auxiliary line.

[0075] In another embodiment, if the annotation type is board edge spacing, then the following steps are included in determining the elements to be annotated of the annotation object according to the annotation type and calculating the annotation data.

[0076] S1221. Obtain the upper left single outer contour of the panel as the first contour, for example Figure 5 The upper left single outer contour LK1 of the illustrated panel is obtained by taking the gong belt contour as the second contour, for example Figure 5 The gong belt outline in LKL;

[0077] S1222, obtaining the panel edge spacing width and the panel edge spacing height as annotation data according to the first upper left point coordinate A1 of the first contour LK1 and the second upper left point coordinate A2 of the second contour LKL;

Generate a horizontal marking auxiliary line L2 at the preset plate edge spacing width marking position, and use the two points A1” and A2” of the horizontal intercepts of the adjacent vertical lines of the first contour and the second contour on the marking auxiliary line as the two anchor points of the plate edge spacing width.

[0080] In an alternative embodiment, the above method is also applicable to determining the anchor point for automatic marking of the process edge width, and it is only necessary to use a single outer contour of the single board as the first contour.

[0081] In one embodiment, if the annotation type is layout spacing, then the following steps are included in determining the elements to be annotated of the annotation object according to the annotation type and calculating the annotation data.

[0082] S1231, confirm the first outer contour of a single piece in the imposition, for example Figure 6 A single profile LK1;

[0083] S1232, confirm the second outer contour of another single piece that is closest to the single piece, for example Figure 6 Another single outline LK2 in the embodiment, determining the layout pitch height according to the coordinates of the first outer outline LK1 and the second outer outline LK2;

[0085] S1234: Generate a vertical marking auxiliary line L1 at a preset layout height marking position, and use two points H1' and H2' of the longitudinal intercepts of the adjacent horizontal lines H1 and H2 of the first and second outer contours on the marking auxiliary line L1 as two anchor points for the layout height;

[0086] S1235. Generate a horizontal marking auxiliary line L2 at the preset imposition spacing width marking position, and use the two points S1' and S2' of the transverse intercepts of the adjacent vertical lines S1 and S2 of the first outer contour LK1 and the third outer contour LK3 on the marking auxiliary line L2 as two anchor points of the imposition spacing width.

[0087] S130: Generate and display a marked graphic based on the marked data.

[0088] In one embodiment, generating and displaying the annotation graphics according to the annotation data includes the following steps.

[0089] S131, determining whether the distance between the two anchor points is greater than a marking threshold;

[0090] S132: If the value is greater than the annotation threshold, directly connect the two anchor points and draw a line segment for linear annotation;

[0091] S133. If the value is less than or equal to the annotation threshold, the two anchor points are rotated and offset, and then connected by drawing a line segment for alignment annotation. In one embodiment, the annotation threshold may be the minimum spacing occupied by the annotation data.

[0092] S134. Generate a corresponding arrow graphic according to the coordinates of the anchor point.

[0093] Specifically, generating a corresponding arrow graphic according to the coordinates of the anchor point includes the following steps.

[0094] S1341. Connect two anchor points to form an auxiliary line;

[0095] S1342, offsetting the anchor point along the auxiliary paving line by a first preset distance to obtain an auxiliary point;

[0096] S1343: Rotate the auxiliary point with the anchor point as the base point, and symmetrically deviate the auxiliary point by a second preset distance on both sides of the auxiliary line to obtain a first angle point and a second angle point;

[0097] S1344. Connect the anchor point, the first angle point, the second angle point, and the anchor point in sequence to draw a line segment to form an arrow icon.
