As shown in Figure 3, step S15 of Figure 2 may include: step S151: obtaining the part package of the part from the parts list based on the part name; and step S153: using language integration query to obtain line data based on the part package.

As mentioned before, the parts list can record the part names of various parts and the part packages corresponding to the parts names. Therefore, in step S151, the processing device 12 can determine the part name of the target part in the parts list followed by the text of the part package, so as to search for the data recorded after the part package in the following step S153.

In step S153, the processing device 12 may use a language integrated query (LINQ) to obtain the line data of the component package, where the line data may indicate the appearance of the component package, such as a straight line or a curve.

It should be noted that the second coordinate group obtained by the processing device 12 in step S13 of FIG. 2 may include multiple second coordinates. As shown in Figure 4, step S21 in Figure 2 may include: step S211: sorting the second coordinates according to the vertical axis coordinates and horizontal axis coordinates of the second coordinates of the second coordinate group; and step S213: sorting according to As a result, it is sequentially determined whether each of the multiple boundaries of the enlarged outer frame is located in the non-opening area.

Figure 5 shows both the part outer frame BDY1 and the enlarged outer frame BDY2, and the plurality of first coordinates of the first coordinate group can be the coordinates of multiple points on the part outer frame BDY1 and the center point of the part outer frame BDY1 coordinates. The first coordinate group, after conversion through the transformation matrix, can be the second coordinates of multiple points P0 to P8 on the enlarged outer frame BDY2. The point P0 corresponds to the center point of the part outer frame BDY1, and the points P1 to P8 correspond to the center point of the part outer frame BDY1. These points on the part frame BDY1.

In step S211 , the processing device 12 can sort the second coordinates of the points P1 - P8 according to the horizontal axis (for example, X-axis) coordinates and the vertical axis (for example, Y-axis) coordinates of the second coordinates of the points P1 - P8 , for example, sorting in ascending order. For example, the processing device 12 can sort the second coordinates of the points P1 to P8 as: the second coordinates of P1, P2 according to the sorting rules from the left side to the right side of the processing drawing and from the upper side to the lower side of the processing drawing. The second coordinate of P3, the second coordinate of P4, the second coordinate of P5, the second coordinate of P6, the second coordinate of P7 and the second coordinate of P8. It should be noted that the above sorting rules are only examples, and the present invention does not limit the sorting rules.

Next, in step S213, the processing device 12 can sequentially determine whether each of the multiple boundaries connected by multiple of the points P1 to P8 is located in the non-opening area based on the sorting result. For example, based on the above sorting results, the processing device 12 can first determine whether the boundary formed by connecting points P1 and P2 is located in the non-opening area; and then determine whether the boundary formed by connecting points P2 and P3 is located in the non-opening area. in; then determine whether the boundary formed by connecting points P1 and P4 is located in the non-opening area, and so on. If it is determined that one of the boundaries falls in the non-opening area, the processing device 12 can execute step S23 of FIG. 2 ; if it is determined that none of the boundaries falls in the non-opening area, the processing device 12 can execute FIG. 2 Step S25.

By judging whether each boundary of the enlarged outer frame falls in the non-opening area based on the sorting results, inspection can be carried out in a sequential manner, thereby avoiding missed detection problems.

Please refer to FIG. 6 , which is a schematic diagram of checking whether a part of the non-opening area on the processing drawing falls within the enlarged outer frame. The opening area and non-opening area on the processing drawing can have different colors. As shown in the figure, the opening area of the processing drawing IMG1 can be presented in white, and the non-opening area can be presented in gray. In the processing drawing IMG1, it is located at the four corners. The white circular area can be used as the aforementioned positioning point. After obtaining the sorting result in step S211 of FIG. 4 , the processing device determines whether a part of the non-opening area falls within the enlarged outer frame. The implementation can also be based on the color displayed on the processing image IMG1.

Specifically, the processing device can sequentially determine according to the sorting result whether both sides of each of the boundaries of the enlarged outer frame BDY2' present a color corresponding to the non-opening area, and determine whether there is one of the boundaries. A warning notification is output when both sides present the color corresponding to the non-opening area. Taking Figure 6 as an example, it can be seen from the partial enlarged view IMG2 taken from the processing image IMG1 that both sides of a part of the boundary of the enlarged outer frame BDY2' appear gray corresponding to the non-opening area, so the processing device can Output warning notifications.

In addition, as mentioned above, the number of target parts can be multiple. Therefore, in addition to the above content, in another embodiment, the processing device can perform the following judgment on multiple target parts simultaneously through a multithreading program. Procedure: determine whether a part of the non-opening area falls within the enlarged outer frame, sequentially determine whether each of the multiple boundaries of the enlarged outer frame is located in the non-opening area according to the sorting result, or sequentially determine according to the sorting result It is determined whether both sides of each of the boundaries of the enlarged outer frame present one of the colors corresponding to the non-opening area. For example, the processing device can first determine its own highest execution performance (for example, the highest execution performance can be associated with the number of cores of the processing device), and set the number of threads that can simultaneously execute the check based on the highest execution performance. Then one of the above-mentioned judgment procedures is executed simultaneously on multiple target parts according to the number of threads, and the processing device can first judge whether the target part is an inspected part before executing the judgment procedure to improve inspection efficiency.

In summary, according to the processing drawing inspection system and method shown in one or more embodiments of the present invention, the efficiency and accuracy of checking the milling hole position on the processing drawing can be improved, and the missed detection of the milling hole position caused by manual inspection can be avoided, and thus the milling hole position can be avoided. Improve the situation of parts being crushed by vehicles. In addition, since processing machines may not be able to process the carrier very accurately, the technical means of forming an enlarged frame can make the size of the milled hole enlarged within the allowable range to avoid errors due to part deviation during processing. Causes the problem of parts being crushed. In addition, by judging whether each boundary of the enlarged outer frame falls in the non-opening area based on the sorting results, inspection can be carried out in a sequential manner, thereby avoiding missed detection problems.
