[0039] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme 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.

[0040] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0041] The present invention provides an automatic punching method. Figure 1 is a flowchart of an automatic punching method provided according to an embodiment of the present invention, referring to Figure 1 , automatic punching methods include:

[0042] S110, obtaining the user-defined punching attributes input by the user and the currently edited PCB board size.

[0043] Specifically, the custom punching attributes can be set according to actual needs, and the embodiment of the present invention does not limit this, wherein the custom punching attributes include the outer hole diameter, the inner hole diameter, the initial layer of the punching and the end layer of the punching, the distance between adjacent pre-punching positions, and the distance between the punching position and the edge of the PCB board. Similarly, the user can set the size of the currently edited PCB board according to actual conditions. Therefore, the automatic punching method designed in the embodiment of the present invention can be applied to PCB boards of any size, and has a wide range of applications.

[0044] S120, calculating all pre-punching positions on the PCB board according to the user-defined punching attributes input by the user and the currently edited PCB board size.

[0045] Specifically, all pre-punching positions on the currently edited PCB board may be calculated according to the distance between adjacent pre-punching positions, the distance between a punching position and an edge of the PCB board, and the size of the currently edited PCB board.

[0046] S130, obtaining all network attributes involved in the current PCB board, and recording the characteristic value corresponding to the network attribute being GND, wherein each network attribute corresponds to a type of component.

[0047] Among them, the network properties of different PCB boards can be set differently according to the different design habits of designers. Therefore, different designers will use the characteristic values ​​corresponding to the GND network properties differently. For example, designer A can set the characteristic value corresponding to the GND network property to 1, and designer B can set the characteristic value corresponding to the GND network property to 2.

[0048] S140. Based on all the calculated pre-punching positions on the PCB board, determine whether there are other components in the obstacle avoidance determination range for each pre-punching position of the PCB board; if so, skip the current pre-punching position, and determine whether there are other components in the obstacle avoidance determination range for the next pre-punching position; if not, assign the user-defined punching attribute input by the user to the current pre-punching position, and store the feature value in the custom data unit corresponding to the current pre-punching position.

[0049] Among them, the obstacle avoidance judgment range can be set based on the design rule check (DRC). Specifically, when there are no other components in the obstacle avoidance judgment range of the current pre-punching position, the software applying the automatic punching method will store the user-entered custom punching attributes and the characteristic values ​​corresponding to the current PCB board GND network attributes in the storage unit corresponding to the current pre-punching position, so as to facilitate automatic hole drawing according to the stored custom punching attributes and the characteristic values ​​corresponding to the current PCB board GND network attributes after completing the judgment of whether there are other components in the obstacle avoidance judgment range of all pre-punching positions on the PCB board, wherein the storage unit is the custom data unit described in the embodiment of the present invention.

[0050] S150, according to the characteristic value in each custom data unit, determine all the positions where holes need to be punched in the currently edited PCB board, and automatically draw holes at the positions where holes need to be punched.

[0051] Specifically, the pre-punched position of the network attribute GND is the position where a hole needs to be punched.

[0052] The automatic punching method provided in the embodiment of the present invention can perform punching settings for a PCB board of any size by the user inputting a custom punching attribute and the currently edited PCB board size, and has a wide range of applications. According to the custom punching attribute input by the user and the currently edited PCB board size, all pre-punching positions on the PCB board are calculated, and then according to all the calculated pre-punching positions on the PCB board, it is judged whether there are other components in the obstacle avoidance judgment range for each pre-punching position of the PCB board, and the pre-punching position without other components is assigned a characteristic value corresponding to the GND network attribute. After all the pre-punching positions are judged, holes are automatically drawn at the positions where holes need to be punched according to the characteristic values ​​and the custom punching attributes. Compared with the existing manual punching, the punching method of this embodiment greatly improves the punching efficiency and saves more than 95% of the punching time of the original manual punching.

[0053] Figure 2 is a flowchart of another automatic punching method provided according to an embodiment of the present invention. Figure 2 On the basis of the above technical solution, step S140 is performed based on all the calculated pre-punching positions on the PCB board to determine whether there are other components in the obstacle avoidance determination range for each pre-punching position within the range of the PCB board; if there are, the current pre-punching position is skipped, and whether there are other components in the obstacle avoidance determination range for the next pre-punching position; if there are no other components, the user-defined punching attribute input by the user is assigned to the current pre-punching position, and the characteristic value is stored in the custom data unit corresponding to the current pre-punching position. The optimization is specifically performed, including:

[0054] S210, obtaining the user-defined punching attributes input by the user and the currently edited PCB board size.

[0055] S220, calculating all pre-punching positions on the PCB board according to the user-defined punching attributes input by the user and the currently edited PCB board size.

[0056] S230, obtaining all network attributes involved in the current PCB board, and recording the characteristic value corresponding to the network attribute being GND, wherein each network attribute corresponds to a type of component.

[0057] S2401. Determine a component acquisition range corresponding to the current pre-punching position, and acquire all components within the component acquisition range.

[0058] Among them, the component acquisition range can be set based on the design rule check (DRC). For example, twice the diameter of the design rule check (DRC) range can be used as the side length of the quadrilateral in the component acquisition range. The specific obstacle avoidance range can be set according to actual needs, and the embodiment of the present invention is not limited to this.

[0059] S2402. Determine whether the current component within the component acquisition range is the component to be replaced. If not, skip the current component and determine the next component. If yes, determine whether the distance between the component to be replaced within the component acquisition range and the current pre-punching position is less than the preset distance set in the design rule check. If yes, skip the current pre-punching position and determine the next pre-punching position. If not, assign the custom punching attribute input by the user to the current pre-punching position, and store the characteristic value in the custom data unit corresponding to the hole.

[0060] Among them, the components to be replaced can be holes, wires and pads. Specifically, if the current component within the component acquisition range is not the component to be replaced, it means that punching at the current pre-punching position has no effect on the current component, and thus does not affect the operation of the circuit in the entire PCB board; if the current component within the component acquisition range is the component to be replaced, it can be determined whether the distance between the component to be replaced and the current pre-punching position within the component acquisition range is less than the preset distance set in the design rule check. If it is less than the preset distance set in the design rule check, it means that the current pre-punching position does not meet the punching requirements in the design rule check and is inconvenient to punch. Skipping the current pre-punching position can avoid the problem of punching at the current pre-punching position. , affecting the operation of the circuit in the entire PCB board; if it is greater than or equal to the preset distance set in the design rule check, it means that the current pre-punching position meets the punching requirements in the design rule check, and it is convenient for punching. The custom punching attributes input by the user and the characteristic values ​​corresponding to the GND network attributes of the current PCB board can be stored in the storage unit corresponding to the current pre-punching position through the software applying the automatic punching method, so that after completing the judgment of whether there are other components in the obstacle avoidance judgment range of all pre-punching positions on the PCB board, holes can be automatically drawn according to the stored custom punching attributes and the characteristic values ​​corresponding to the GND network attributes of the current PCB board.

[0061] It is also possible to judge whether the distance between the component to be replaced between the initial punching layer and the end punching layer and the current pre-punching position is less than the preset distance set in the design rule check based on the component acquisition range. For example, assuming that the initial punching layer corresponding to the current pre-punching position is the first layer and the end punching layer corresponding to the current pre-punching position is the seventh layer, it can be judged starting from the first layer whether the distance between the component to be replaced and the current pre-punching position is less than the preset distance set in the design rule check; it can also be judged starting from the seventh layer whether the distance between the component to be replaced and the current pre-punching position is less than the preset distance set in the design rule check. If there are components to be replaced between the first layer and the seventh layer, and the distance between the components to be replaced and the current pre-punching position is less than the preset distance set in the design rule check, it means that the current pre-punching position overlaps with one or some components within the component acquisition range, and it is inconvenient to punch holes. The current pre-punching position needs to be skipped. Skipping the current pre-punching position can avoid affecting the operation of the circuit in the entire PCB board after punching at the current pre-punching position; if there are components to be replaced between the first layer and the seventh layer, or if there are components to be replaced between the first layer and the seventh layer, and the distance between the components to be replaced and the current pre-punching position is greater than or equal to the preset distance set in the design rule check, it means that the current pre-punching position does not overlap with all components in the component acquisition range, and punching has no effect on the normal operation of the circuit in the entire PCB board, so it is convenient to punch holes.

[0062] S250, according to the characteristic value in each custom data unit, determine all the positions where holes need to be punched in the currently edited PCB board, and automatically draw holes at the positions where holes need to be punched.

[0063] The embodiment of the present invention judges whether the current component in the component acquisition range is a component to be replaced according to the component acquisition range designed by the designer, which can reduce the judgment process of non-components to be replaced, increase the judgment efficiency, and further improve the punching efficiency; and when judging whether the current component in the component acquisition range is a component to be replaced, it will judge whether the distance between the component to be replaced in the component acquisition range and the current pre-punching position is less than the preset distance set in the design rule check, which can avoid the internal structure of the circuit being damaged after punching under the condition of less than the preset distance set in the design rule check, thereby affecting the operation of the circuit in the entire PCB board. The embodiment of the present invention further improves the punching efficiency without affecting the operation of the circuit in the entire PCB board, saving more than 95% of the punching time of the original manual punching.

[0064] Optionally, based on all calculated pre-punched hole positions on the PCB board, determining whether there are other components within the obstacle avoidance determination range for each pre-punched hole position within the range of the PCB board includes:

[0065] A first preset number of control units are selected, and each control unit controls to determine whether there are other components within the obstacle avoidance determination range at a second preset number of pre-punched positions, wherein the first preset number and the second preset number are determined by the pre-punched positions on the PCB board.

[0066] Specifically, the number of rows and columns of pre-punched holes can be determined based on all pre-punched hole positions on the current PCB board, and the first preset number can be determined based on the number of rows and columns of pre-punched holes. For example, the maximum value that can be divided by the number of rows / columns of pre-punched holes can be selected in the range of 2-8 as the first preset number, and the second preset number is the number of rows / columns of pre-punched holes divided by the first preset number. Each control unit controls to determine whether there are other components in the second preset number of pre-punched hole positions within the obstacle avoidance judgment range, indicating that the second preset number of pre-punched hole positions can be judged by the first preset number of control units at the same time, which increases the judgment efficiency and further improves the punching efficiency.

[0067] Optionally, the custom punching properties include outer hole diameter, inner hole diameter, punching initial layer and punching end layer, distance between adjacent pre-punching positions, and distance between the punching position and the edge of the PCB board.

[0068] Specifically, by setting different custom punching properties, users can set the size, position, depth and density of the holes according to actual needs, which has a wider application range and can meet the needs of more users. The customization of the distance between adjacent pre-punched positions and the distance between the punching position and the edge of the PCB board can make the distance between adjacent pre-punched positions and the distance between the punching position and the edge of the PCB board shorter, making the punching distance more dense and uniform, and because the grounding holes themselves have the function of common ground, the resistance between the layers in the PCB board can be reduced, and the denser the punching distance, the smaller the resistance between the layers in the PCB board, making the circuit in the PCB board run more smoothly; at the same time, the grounding holes also have the function of shielding the microwave electromagnetic field generated in the microwave circuit. The denser the punching distance, the better the signal shielding effect of the PCB board, making the circuit in the PCB board run more smoothly.

[0069] Optionally, before determining the component acquisition range corresponding to the current pre-punching position and acquiring all components within the component acquisition range, the method further includes:

[0070] Determine whether the punching pattern is a hole-in-pad pattern. If so, the component to be replaced includes a hole and a line; if not, the component to be replaced includes a hole, a line and a pad, wherein the hole-in-pad pattern is a pattern of punching holes in the pad.

[0071] Specifically, when judging whether the punching mode is a hole-in-disk mode, manual operation by the user is required. For example, the software applying the automatic punching method will pop up a judgment box before determining the component acquisition range corresponding to the current pre-punching position and acquiring all components within the component acquisition range. The user can select the current punching mode according to actual needs. If it is determined that the current punching mode is a hole-in-disk mode, the components to be replaced include holes and lines; if it is determined that the current punching mode is not a hole-in-disk mode, the components to be replaced include holes, lines and pads.

[0072] Optionally, after obtaining all components in the component acquisition scope, it also includes:

[0073] It is determined whether components at different corner positions within the component acquisition range are the same components. If they are, it is determined whether only one of the same components is the component to be replaced.

[0074] Specifically, a judgment is added as to whether components at different corner positions within the component acquisition range belong to the same components. If they belong to the same components, it is only necessary to judge whether one of the same components is the component to be replaced, which reduces the judgment time, increases the judgment efficiency, and further improves the punching efficiency.
