Description

A kind of special-shaped glass mirror image cutting method

technical field

The invention relates to the field of deep processing of architectural glass, in particular to a mirror image cutting method of special-shaped glass.

Background technique

Insulating glass or laminated glass for buildings is generally a glass component made of two (or more than three) pieces of glass, which are polymerized using different intermediate polymeric materials. According to the requirements of different types of products, this type of glass needs to undergo processing processes such as cutting, edging, tempering, coating, hollowing or interlayering. The raw materials used in this glass component are all float glass. Since the float glass is divided into two surfaces with different structures, the air surface and the tin surface, the chemical stability of these two surfaces is different due to their different structures. The air surface is relatively It is easy to mildew, so when synthesizing the hollow or interlayer, it is necessary to close the air surface in the relatively airtight middle.

For glass with special-shaped structure (irregular graphics), since it cannot be turned over arbitrarily, it is necessary to mirror the second layer of glass and cut after cutting to ensure that the air surface is in the middle and the two graphics are completely overlapped. The second mirroring method of the special-shaped layer in the prior art is to mirror the graphics of the first layer in the cad one by one, and then rearrange according to the method of the first layer, optimize and convert it into a file that can be recognized by the machine for cutting.

The current method of cutting the second image of the special-shaped layer has the following disadvantages:

1. In order to mirror, it is necessary to call out the special-shaped graphics that have been ordered into the system, and then manually mirror them in cad, and then save them in the system again, optimize the typesetting, and convert them into machine-recognized files, which are prone to errors during the manual mirroring process .

2. The mirror image of cad graphics is equivalent to re-drawing, which increases the workload and relatively low efficiency.

3. After mirroring in CAD, it is necessary to place an order again for optimization, and re-optimization will result in a different output sequence from layer 1, and the correct layer sequence pairing cannot be ensured when it is hollow.

Detailed ways

The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

Example 1

A flow chart of a special-shaped glass mirror image cutting method is shown in Figure 1, specifically comprising the following steps:

A. Obtain the original graphic data of special-shaped glass.

The original data mainly refers to the dimension data of layer one of special-shaped glass. First, optimize the glass graphics that have been ordered, export them as dat files that the machine can recognize, and find the dat files corresponding to the special-shaped graphics from all the dat files and open them. The schematic diagram of the exported dat file and the dat file corresponding to the selected special-shaped figure is shown in Figure 2.

B. Obtain shape parameters of special-shaped graphics.

Classify and identify the dat file corresponding to the opened special-shaped figure, and the data in the dat file corresponding to the opened special-shaped figure is shown in Figure 3. Identify the data representing the containment rectangle, the data representing the containment rectangle includes the length of the containment rectangle and the width of the containment rectangle (the first row of data in Figure 3: 1240, 840), and the data group representing the containment rectangle as The first set of data. And read out the value of the line segment representing the line of the special-shaped figure; Finally, identify the data group representing the shape parameter of the special shape, as the second data group, the data group representing the shape parameter of the special shape is shown in Figure 5, the data group representing the shape parameter of the special shape is the last six rows of data in the first group of data .

C. Identify the types and coordinates of the constituent elements of the special-shaped graphics.

According to the line segment value representing the special-shaped graphic line, the type of each line is determined segmentally, and the graphic coordinate element corresponding to each line is obtained from the second array. In this embodiment, as shown in FIG. 5 , the data of the shape parameter of the special shape is five lines, so the line segment value of the line of the special shape figure is 5. Determine the graphic element by the third data of the graphic coordinate element in each line. If the third number is 0, it means that the element is a straight line, otherwise it is an arc. When the line is a straight line, identify the starting point and end point coordinates of the line. For example, the graphic element of the first line segment is 20 20 0 20 1220 1000, and the third number is 0, indicating that the line is a straight line. The two values before 0 It means that the starting point coordinates of the straight line segment are (20, 20), and the two numbers after 0 represent the ending coordinates of the straight line segment, which is (1220, 20). The judgment method of the starting point coordinates of the straight line segment in other lines is the same as the above process , thus, the starting point coordinates of all straight line segments in the special-shaped figure are obtained. The graphic element of the third line is 720 320500 0 1.5707996326 1000. Since the third number is not 0, the line is an arc, and the first two numbers of the third number represent the coordinates of the center of the circle, which is (720, 320 ), the value of the third number is the radius, which is 500, the fourth number represents the starting arc, which is 0, and the fifth number represents the ending arc, which is 1.5707996326, thus, the arc in the special-shaped figure is obtained related parameters.

D. Calculate the mirror image coordinates of the special-shaped figure.

The special-shaped figure is contained in a rectangular frame. When the line is a straight line, the respective X coordinates are subtracted from the length in the containing rectangular frame to obtain the X coordinate of the mirrored figure, while the Y coordinate of the mirrored figure remains unchanged. Obtain the length of the enclosing rectangle from the data group of the enclosing rectangle, which is 1240 in this example. Therefore, the first line segment in this example (the starting point coordinates are (20, 20) and the ending point coordinates are (1220, 20) )’s mirrored line segment X coordinate is 1240-20=1220 and the end point’s X coordinate is 1240-1220=20, then the starting point coordinate of the mirrored line segment of the first line segment is (1220, 20), and the end point coordinate is (20, 20). The calculation method of the start point coordinates and end point coordinates of mirrored line segments of other straight line segments is the same as that of the first line segment.

When the line is arc-shaped, subtract the X coordinate of the center of the circle from the length of the enclosing rectangle to obtain the corresponding X coordinate of the mirror image of the center of the circle, and the Y coordinate remains unchanged. In the illustration, subtract the radian of the starting point and the arc of the end point with π , to get the starting point radian and ending point radian of the mirror image. In this example, the center of the mirror image image of the third line (arc) is (1240-720, 320), which is (820, 320). The starting arc of the mirror image is 3.1415926-0=3.1415926, and the end arc of the mirror image is 3.1415926-1.5707996326=1.5707929674.

E. According to the generated X-coordinate of the mirror image, the shape data of the corresponding mirror image of the special-shaped figure is generated. After calculating the X value of each line segment of the mirrored graphic, and the original Y value to generate the graphic shape parameter of the mirrored graphic.

F. According to the graphic shape parameters of the mirrored graphic, a data file of the corresponding mirrored graphic of the special-shaped graphic is generated. Write the coordinates of the generated graphics data into the graphics file according to the location of the graphics file, and save it as a Txt file. When generating the Txt file of the mirror image, the order of the dat file of the layer-size data of the special-shaped glass is the same as that of the corresponding mirror image. Txt files are in the same order. Therefore, without changing the size and order of the rectangles contained in the periphery, it is ensured that the film output sequence of layer 1 and layer 2 is exactly the same, and the production matching of the assembling process is guaranteed.

G. Through the above-mentioned steps A-F, the mirror image processing of a special-shaped glass graphic file can be completed. When there is a batch of special-shaped glass that needs to be processed, step A-F is executed cyclically in order to generate a batch of mirror txt files of the special-shaped glass graphic file.

Use a computer program to complete the mirroring of all graphic files according to the above procedure, and generate a new graphic txt file. The computer program is as follows:

a1 = Range("a1")

h = 32

For j = 1 To Range("b3")

h = h + 1

If Range("c" & h & "") = 0 Then

a = Range("d" & h & "")

b = Range("e" & h & "")

Range("d" & h & "") = a1 - a

Range("e" & h & "") = a1 - b

Else

a = Range("d" & h & "")

b = Range("e" & h & "")

c = Range("a" & h & "")

b = Range("e" & h & "")

Range("d" & h & "") = 3.1415926 - a

Range("e" & h & "") = 3.1415926 - b

Range("a" & h & "") = a1 - c

End If

Next j

:=xlText, CreateBackup:=False

Application. DisplayAlerts = False

Sheets(Sheets. Count). Delete

Sheets("sheet1"). Select

Next i

End Sub

H. File conversion.

Convert the image txt file of the special-shaped glass graphics file into a recognizable dat file. When the image txt file of the special-shaped glass graphics file is batch data, it will be converted into a recognizable dat file in batches. Convert the txt files generated by the above program into dat files that can be recognized by the machine in batches. All the tools used are the conversion applet rename.bat, the icon of the conversion applet is shown in Figure 6, and the conversion diagram is shown in Figure 7.

I. Output cutting.

Merge the dat file of layer one dimension data of the special-shaped glass and the dat file of the special-shaped glass graphics file into a whole dat file, output the whole dat file to the cutting machine, and cut the special-shaped glass after mirroring.

Fig. 8 shows the dimension diagram of the special-shaped glass pattern before mirroring, and Fig. 9 shows the dimension diagram of the special-shaped glass pattern after mirroring obtained by the method of the present invention. It is proved by experiments that the method of the present invention realizes full automation of data processing, and the probability of error is almost zero; the use of one-time drawing for multiple utilization improves the efficiency of order placement and optimization. And because only the special-shaped graphics in the machine file are mirrored, and the size and order of the surrounding rectangles are not changed, it is ensured that the film output sequence of layer 1 and layer 2 is exactly the same, ensuring the production matching of the assembling process and improving production efficiency.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention within.
