Description

System and method for generating punch parts and corresponding holes on stamping templates

The invention relates to an automatic inspection system and method for unsealed graphics of stamping dies.

In the stamping die design, the original design part method is hand-drawn, not only the design quality of the parts is very poor, but also the work efficiency is very low. With the rapid development of computer technology, a large number of stamping die design software emerged. These stamping die design softwares are not only easy to operate, but also have better design quality than manual design, which greatly improves the efficiency and precision of stamping die design. However, there are some shortcomings in the automation of stamping die design software. The main aspect is that the design of the part graphics usually has closed and unclosed graphics. In the stamping die design software, the line (which can be a straight line or a curve) that draws the graphic cut surface pattern is continuous, and there is no break point in the middle. If the starting point and the end point of the drawing are on the same coordinate, the graphic is closed. A graphic, for example, a complete circular shape is a closed graphic. If the starting point and the ending point of the drawing are not on the same coordinate, the graphic is an unclosed graphic. For example, a semicircle is an unclosed graphic.

As stamping dies are becoming more and more sophisticated and more complex, usually a mold has hundreds or thousands of parts, and the mold designer can only pass the traditional method. At the same time, the naked eye and the experience spend a lot of effort to check whether the starting point and the end point of the graph coincide to determine whether the graphic is closed, which is time consuming and cannot be completely correct, so errors and omissions sometimes occur.

In view of the above, it is necessary to provide an automatic inspection system for an unsealed pattern of a stamping die, which can find out an unclosed figure by verifying whether the coordinates of the start point and the end point of the graph cut surface are the same.

In view of the above, it is also necessary to provide an automatic inspection method for an unclosed pattern of a stamping die, which can find out an unclosed figure by verifying whether the coordinates of the start point and the end point of the graph cut surface are the same.

A stamping die unclosed graphic automatic inspection system includes a host and a graphic database, wherein the graphic database is used for storing various graphic materials, and the host comprises: a selecting module for selecting a check from the graphic database. a determining module, configured to determine whether the graphic has attribute information, the attribute information includes information about whether the graphic is closed, and the determining module is further configured to determine the attribute when the graphic has attribute information Whether there is corresponding information indicating the closed graphic in the information; the reading module is configured to read the coordinates of the starting point and the ending point in the graphic cut surface when the corresponding information of the graphic information is marked in the graphic information of the graphic; A group that compares the coordinates of the read start and end points to determine if they are different.

A method for automatically checking an unsealed pattern of a stamping die, the method comprising the steps of: selecting a graphic to be inspected from a graphic database; determining whether the graphic has attribute information, and the attribute information includes information on whether the graphic is closed; When the attribute information of the graphic exists, determining whether there is corresponding information indicating that the graphic is closed in the attribute information; when the attribute information of the graphic has corresponding information indicating that the graphic is closed, reading the starting point and the ending point in the graphic cut surface Coordinates; compare the coordinates of the read start and end points to determine if they are different.

Compared with the prior art, the stamping die unclosed graphic automatic inspection system and method can verify the unclosed figure by verifying whether the coordinates of the starting point and the end point of the graphic cut surface are the same, and after checking The graphics are identified in a specific color to ensure that no defects are missed during inspection, thus improving the accuracy of the mold design.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a hardware structural view of a preferred embodiment of an automatic inspection system for an unsealed pattern of a stamping die of the present invention.

2 is a functional block diagram of the host shown in FIG. 1.

3 is a flow chart of a preferred embodiment of an automatic inspection method for an unsealed pattern of a stamping die of the present invention.

As shown in Fig. 1, it is a system architecture diagram of a preferred embodiment of the automatic inspection system for the unsealed pattern of the stamping die of the present invention. The system mainly comprises a display 1, a host 2, a keyboard 3 and a mouse 4, and the host 2 is connected with a graphic database 5. The graphic database 5 stores various graphic materials. The graphic material includes a cut-away view of the graphic, a coordinate position and a specification of the cut-away view. The graphic data may also include attribute information of the graphic. The attribute information of the graphic includes the processing mode and the graphic is No information such as closure. Usually in the mold design, when a certain graphic design is made, the above attribute information is associated with the graphic. Since the attribute information is not automatically generated during the graphic design, the graphic may have attribute information or no attribute information. In the mold design software, the line (which can be a straight line or a curve) that draws the graphic cut surface pattern is continuous, and there is no break point in the middle. If the start point and the end point of the drawing are on the same coordinate, the graphic is a closed figure. For example, a complete circle is a closed figure. If the start and end points of the drawing are not on the same coordinate, the figure is an unclosed figure. For example, a semicircle is an unclosed figure.

The host 2 is configured to display the graphic in a specific color according to the result of the comparison according to the comparison between the start point and the end point coordinate of the graphic selected in the database 5, thereby determining whether the graphic is closed. The host 2 is connected with a display 1, a keyboard 3, and a mouse 4, and is used as an input and output device in a specific operation.

As shown in FIG. 2, it is a functional module diagram of the host 2 shown in FIG. The host 2 includes a selection module 210, a determination module 211, a reading module 212, a comparison module 213, and an identification module 214. The module referred to in the present invention is a computer program segment for performing a specific function, and is more suitable for describing the execution process of the software in the computer than the program. Therefore, the following description of the software is described in the module.

The selection module 210 selects a graphic to be inspected from the graphic database 5. The method of selection may be automatically selected according to the order of the part numbers, or one or a few figures may be selected by the part number as required.

The determining module 211 is configured to determine whether the graphic has attribute information. Place The attribute information described includes information such as the processing method and whether the graphic is closed. Usually in the mold design, when a certain graphic design is made, the above attribute information is associated with the graphic. Since the attribute information is not automatically generated during the graphic design, the graphic may have attribute information or no attribute information. In the stamping die design software, the line (which can be a straight line or a curve) that draws the graphic cut surface pattern is continuous, and there is no break point in the middle. If the starting point and the end point of the drawing are on the same coordinate, the graphic is closed. A graphic, for example, a complete circular shape is a closed graphic. If the starting point and the ending point of the drawing are not on the same coordinate, the graphic is an unclosed graphic. For example, a semicircle is an unclosed graphic.

The determining module 211 is further configured to: when the attribute information exists in the graphic, determine whether the attribute information indicates that the graphic is closed.

The reading module 212 is configured to read the coordinates of the start point and the end point in the graph cut surface when the attribute information of the graphic has corresponding information indicating that the graphic is closed.

The comparison module 213 is configured to compare the coordinates of the read start point and the end point.

The identification module 214 is configured to identify the compared graphic according to the result of the comparison. The graphics can be identified by color or by digitally marking the lines of the graphics. In the preferred embodiment, the method used is a color identification. Specifically, after comparing the coordinates of the read start point and the end point, if the start point and the end point coordinate are not the same, indicating that the figure is not closed, then The graphic shows red if the starting point If it is different from the end point, it will be yellow.

As shown in Fig. 3, it is a flow chart of a preferred embodiment of the automatic inspection method for the unsealed pattern of the stamping die of the present invention.

In step S10, first, the graphic to be inspected is selected from the graphic database 5. The method of selection may be automatically selected according to the order of the part numbers, or one or a few figures may be selected by the part number as required.

In step S11, it is determined whether the graphic has attribute information. The attribute information includes information such as processing mode and whether the graphic is closed. Usually in the mold design, when a certain graphic design is made, the above attribute information is associated with the graphic. Since the attribute information is not automatically generated during the graphic design, the graphic may have attribute information or no attribute information. In the stamping die design software, the line (which can be a straight line or a curve) that draws the graphic cut surface pattern is continuous, and there is no break point in the middle. If the starting point and the end point of the drawing are on the same coordinate, the graphic is closed. A graphic, for example, a complete circular shape is a closed graphic. If the starting point and the ending point of the drawing are not on the same coordinate, the graphic is an unclosed graphic. For example, a semicircle is an unclosed graphic.

Step S12: When the attribute information of the graphic exists, it is determined whether the corresponding information indicating the closed graphic is included in the attribute information.

Step S13: When the attribute information of the graphic has corresponding information indicating that the graphic is closed, the coordinates of the start point and the end point in the graphic cut surface image are read.

In step S14, the coordinates of the read start point and the end point are compared.

In step S15, the compared figure is identified according to the result of the comparison. The way to identify the graphic can be identified by color or by digitally marking the line of the graphic. In the preferred embodiment, the method used is a color identification. Specifically, after comparing the coordinates of the read start point and the end point, if the start point and the end point coordinate are not the same, indicating that the figure is not closed, then The graphic shows red, and if the start and end coordinates are not the same, yellow is displayed.

In step S11, if the graphic has no attribute information, it proceeds directly to step S13.

In step S12, if the attribute information does not indicate the corresponding information of the graphic closure, the process is directly ended.

It should be noted that the above embodiments are only intended to illustrate the technical solutions of the present invention and are not intended to be limiting, and the present invention will be described in detail with reference to the preferred embodiments thereof The technical solutions are modified or equivalently substituted without departing from the spirit and scope of the technical solutions of the present invention.
