Punch block error prevention inspection system and method

The invention relates to a two-dimensional graphic error-proofing inspection system and method, in particular to a punch-in block error-proofing inspection system and method.

In the field of mold design, the inserts embedded in the template are called punches or blocks, collectively referred to as punches. When assembling the punch into the block, the assembler may inadvertently put the punch into the block, or insert the punch into the wrong position, so that the punch is damaged during use, resulting in waste of resources. With the development of two-dimensional design technology and the maturity of error-proof technology, error-proof technology has been widely used in the field of two-dimensional design, and gradually applied to the design of punch into the block. The inclusion of error-proof processing in the design of the punch-in block can effectively prevent the above-mentioned errors from occurring. However, the error-proof processing of the punch into the block is only a small change in the punching into the block. These small changes are difficult to distinguish with the naked eye, and it is difficult for the designer to accurately determine whether the error-proof processing is omitted in the design of the punched block.

In view of the above, it is necessary to provide a punch-in block error-proofing inspection system and method, which can conveniently and efficiently check whether the design of the punch-in block misses the error-proof processing.

In the field of mold design, the inserts embedded in the template are called punches or blocks, collectively referred to as punches. A primitive is the basic unit that makes up a two-dimensional graph. A punch into a block is called a punch-in-block primitive in a two-dimensional graph. The idea of the invention is that if the outer contours of the two punched block primitives are the same, but the internal graphics are different or the thickness is different, the two punched block primitives are missing error prevention processing (hereinafter referred to as error-free processing). ). According to this idea, The present invention detects the punch-in block primitive without error-proof processing by comparing the outer contour, the inner shape, and/or the thickness of the punch into the block primitive.

Referring to FIG. 1, it is an application environment architecture diagram of a preferred embodiment of the punch-in block error-checking system of the present invention. The punch-in block error-proof checking system 10 runs in a computer 1, which includes a graphics storage area 11 for storing two-dimensional graphics. The punch-in block error-checking system 10 includes a receiving module 100, a to-be-searched element search module 101, an error-proof checking module 102, and an output module 103.

The receiving module 100 is configured to receive a two-dimensional graphic to be inspected from the graphic storage area 11. In two-dimensional graphics, different types of primitives are usually placed in different layers, and layer information is set for each primitive to identify the layer to which it belongs, such as punch-in-block primitives, contour primitives, and boundary diagrams. The meta- and center-line primitives are placed in the sub-layer, the contour layer, the boundary layer, and the centerline layer. Two-dimensional graphics that need to be checked usually contain primitives from multiple layers. It should be noted that although the primitives are placed in different layers according to the primitive type, each layer may not be completely the same type of primitives. For example, the input sublayer may include some non-punch into the block diagram. yuan. Each element in a layer is usually represented by three views, a main view, a right view, and a top view.

The to-be-searched primitive search module 101 is configured to search for a punched in-picture primitive to be inspected from the received two-dimensional graphics. The specific method is as follows:

(1) According to the layer information of each primitive, the primitives of the non-sub-layer are removed from the received two-dimensional graphics, and the primitives of the sub-layer are obtained. The input sublayer includes a main view, a bottom view, and a right view.

(2) Remove the lower view and right view primitives from the sublayer layer primitives to obtain the main view primitives of the sublayer.

(3) Remove the non-punch into the block primitive from the main view primitive of the incoming sublayer, and obtain the punch into the block primitive. If the start point and the end point of a certain feature line coincide, the outer contour of the picture element is closed. If the start point and the end point of the outline line do not coincide, the outer contour of the picture element is not closed. The primitive whose outer contour is not closed is a non-punch into the block primitive, and the primitive whose outer contour is not closed can be removed to obtain the punched into the block primitive.

The error-proof checking module 102 is configured to combine the obtained punch-in block primitives to obtain a plurality of different primitive groups, and perform two punches included in each primitive group into the block primitives one by one. Comparing to search for a set of primitives without error-proof processing in the plurality of primitive groups. Among them, the set of primitives without error-proof processing refers to the group of primitives with the same outer contours of the two punched-in blocks, but different internal figures or different thicknesses. The specific method is as follows: the obtained punches are combined into two block elements to obtain a plurality of different primitive groups; one primitive group is taken out from the obtained primitive group; and two punches in the primitive group are compared The outer contour of the block primitive; if the outer contour is not the same, the primitive group is not a primitive group without error-proof processing, or, if the outer contour is the same, compare two punch-in-block primitives in the primitive group Internal graphics; if the internal graphics are not the same, the primitive is a set of primitives without error-proof processing, or, if the internal graphics are the same, further compare the thickness of the two punched primitives in the primitive If the thickness is not the same, the tuple is a tuple group without error-proof processing, or if the thickness is the same, the tuple is not a tuple group without error-proof processing; recording the primitive without error-proof processing Group; until all the primitive groups have been compared.

The output module 103 is configured to output a searched non-error-corrected primitive group.

Referring to Figure 2, there is shown a flow chart of a preferred embodiment of the punch-in block error checking method of the present invention.

In step S201, the receiving module 100 receives the two-dimensional graphics to be inspected from the graphics storage area 11.

The meta- and center-line primitives are placed in the sub-layer, the contour layer, the boundary layer, and the centerline layer. Two-dimensional graphics that need to be checked usually contain primitives from multiple layers. It should be noted that although the primitives are placed in different layers according to the primitive type, each layer may not be completely the same type of primitives. For example, the input sublayer may include some non-punch into the block diagram. yuan. Each element in a layer is usually represented by three views, a main view, a right view, and a top view.

The input sublayer includes a main view, a bottom view, and a right view.

Step S203, the to-be-searched primitive search module 101 removes the lower view and the right view primitive from the sub-layer layer primitive, and obtains the sub-layer main view primitive.

In step S204, the to-be-searched primitive search module 101 removes the non-punch-incorporated primitive from the sub-layer main view primitive to obtain the punch-in block primitive. If the start point and the end point of a certain feature line coincide, the outer contour of the picture element is closed. If the start point and the end point of the outline line do not coincide, the outer contour of the picture element is not closed. The primitive whose outer contour is not closed is a non-punch into the block primitive, and the primitive whose outer contour is not closed can be removed to obtain the punched into the block primitive.
