Problems solved by technology

[0002] At present, in the production process of corrugated paper, the thickness of corrugated paper is generally tested. In the production line, the corrugated paper whose thickness is lower than the user's required value is eliminated to prevent the corrugated paper whose thickness does not meet the standard from entering the subsequent production process and reduce the number of unqualified products. output, improve the qualified rate, the detection method is usually to use the traditional ruler to detect the thickness of corrugated paper, this purely manual thickness detection method has the disadvantages of low efficiency, low precision, etc., and the labor cost is high, and the detection is subjective

Embodiment １

[0041] like Figure 1-2 As shown, the corrugated paper thickness detection method is based on the hardware system. The hardware system includes workbench T, foreground board S1, background board S2, camera SXQ, and computer; foreground board S1 is fixedly installed on the right end of the workbench T; At the left end of the workbench T; the camera SXQ is fixedly installed on the right side of the workbench T and above the workbench T. In the horizontal direction, the camera SXQ has a limited shooting range, and the upper boundary of the shooting range of the camera SXQ is shooting The upper limit SXQ-SX, the lower boundary of the shooting range of the camera SXQ is the shooting lower limit SXQ-XX; the computer and the camera SXQ are connected by communication; During this period, the horizontal line where the lower plane of the foreground board S1 is located is lower than the shooting lower limit SXQ-XX, the horizontal line where the upper plane of the background board S2 is l...

Embodiment ２

[0046] like image 3 As shown, based on Example 1, the method for detecting the thickness of corrugated paper, the operation steps of process b are as follows:

[0047] Step 1: The computer obtains the captured image from the camera SXQ;

[0048] Step 2: The computer judges whether the boundary line S-BJ in the collected image is complete; if the boundary line S-BJ is complete, the thickness of the corrugated paper sample YP between the foreground plate S1 and the background plate S2 is lower than the lower limit of the standard. The inspection of the section is unqualified; if the boundary line S-BJ is incomplete, the thickness of the corrugated paper sample YP between the foreground sheet S1 and the background sheet S2 is higher than the lower limit of the standard, and the inspection of this section is qualified.

Embodiment 3

[0050] like Figure 4-5 As shown, based on implementation 1, the operation steps of process b are as follows:

[0051] Step 1: The computer obtains the captured image from the camera SXQ;

[0052] Step 2: Step 2 has the following sub-operations:

[0053] Step 2.1: The computer counts the color and the proportion of each color in the image;

[0054] Step 2.2: Determine primary and secondary colors;

[0055] Step 2.3: Determine detection boundaries and measurement thresholds;

[0056] Step 2.4: Record the number of boundary points in each column;

[0057] Step 2.5: Count the row with the largest number of border points, which is called the border row;

[0058] Step 2.6: Calculate the boundary point of the boundary line, and the proportion of the boundary line, which is called the boundary proportion;

[0059]Step 2.7: Determine whether the boundary ratio is greater than the preset value; if the boundary line S-BJ of the boundary line is complete, the thickness of the corru...

Abstract

The invention relates to corrugated paper processing. The corrugated paper thickness detection method is based on a hardware system. The hardware system comprises a workbench, a foreground plate, a background plate, a camera, a computer and a display. Firstly, a corrugated paper sample is placed on the surface of a workbench, a camera starts to collect images, if the images only comprise foreground plate colors and background plate colors, the thickness of the corrugated paper sample is lower than the height of a foreground plate, and the section is detected to be unqualified; and if the imageshot by the camera comprises the foreground plate color, the boundary line, the corrugated paper sample color and the background plate color, the thickness of the corrugated paper sample is higher than the height of the foreground plate, and the work section is detected to be qualified. The corrugated paper production quality monitoring system adopts the corrugated paper thickness detection method to detect the corrugated paper quality. The detection result accuracy is improved, the production efficiency is improved, the system reliability degree is increased, the equipment manufacturing costis low, maintenance is easy, and the maintenance cost is reduced.
