Detailed ways

The specific content and working process of the present invention will be further described below in conjunction with the embodiments described in the accompanying drawings.

The present invention solves the above-mentioned technical problems by adopting the following technical scheme: bundle 20-30 ingots of monofilament viscose fibers together and wrap them with a shading cover. After making the shading cover, put it into the viscose fiber cutting device. Refer to Figure 17 to make viscose fiber slices. See Figure 13 for the slicer. Put the prepared viscose fiber slices together with the slicer into the microscopic imaging system. The imaging system is mainly composed of: light source, two-dimensional mobile base, microscopic imaging lens and CCD camera. Since each sticky fiber in the sticky fiber slice cannot be just in a vertical state, resulting in uneven imaging, a hemispherical LED light source is specially designed for this purpose, see Figure 19. The light emitted by the light source passes through the viscose fiber section, and after being amplified by the microscopic optical system, it is imaged at the CCD camera. The CCD camera transmits the acquired digital image to the computer, and performs specific digital image processing on it. The main processing flow is shown in Figure 20. Firstly, the image is collected, and since the collected image contains relatively large noise, noise removal is performed on the obtained image. The noise-removed image has the problem of dark brightness and inconspicuous contrast, so it is necessary to enhance the image. Then the image is segmented by the adaptive threshold segmentation method based on the gradient operator. In order to eliminate the local adhesion phenomenon of the image after segmentation, the image connection area is separated. Finally, count the number of viscose fibers and analyze their morphology on the separated image, and give the result of discrimination.

The present invention is mainly composed of the following important parts: see Figure 2 for the automatic production device of the bundled viscose shading cover; see Figure 17 for the viscose fiber cutting device; see Figure 19 for the lighting device; see Figure 19 for the stereo microscope with a two-dimensional mobile workbench 18; Refer to Fig. 20 and Fig. 21 for image acquisition and image processing subroutines.

Placed in the paper tape clamping shaft 1, the paper passes under the paper tape pressing wheel 2 and is pressed down with it. In order to increase the pressing force, a rough rubber cover is housed on the paper tape pressing wheel 2 to increase friction, and the up and down position of the paper tape pressing wheel 2 can be adjusted to adjust the size of the pressing force. After the paper tape passes through the paper tape pressing wheel 2, it passes under the paper tape cutting and forming tool 3. The paper tape cutting and forming tool 3 is the paper tape cutting and forming part. Both sides are equipped with forming knives, which can move up and down, relying on the spring reset. Its structure is shown in Figure 5. 4 is a vertical plate, and 16,22 are guide columns, which are fixed on the vertical plates, and springs 17,20 are respectively enclosed within the cylindrical guide rods of the guide column 16,22. Paper tape cutting forming cutter 3 is enclosed within on the guide column 16,22. The specific structure of the tool is shown in Figure 7. Among Fig. 7, left and right blade 25,27 are fixed with blade pressing block 24 respectively, and main blade 26 is clamped and fixed with two wedge-shaped blocks 28. In this way, the three blades mounted in 900 positions form a blade on one side, with the same knife structure on the other side of the vertical plate. 21 is the paper tape pressing block, and its structure is as shown in Figure 6, and the circular hole of positioning is arranged on it, is enclosed within respectively on the cylindrical guide bar of two guide columns. The middle groove of paper tape pressing block 21 is a guide groove, and two sets of cutters are positioned at vertical plate 4 both sides, and pass under paper tape pressing block 21 after paper tape passes through paper tape pressing wheel 2. Press the paper tape cutting forming cutter 3, and the paper tape pressing block 21 will press the paper tape on the vertical plate 4, and the cutter will cut off the paper tape along the guide groove of the paper tape pressing block 21. In order to enable the paper tape to be completely cut off, guide grooves 23 are also processed at corresponding positions on the vertical plate 4, and there are both sides. Paper is cut into T shape like this, after decontroling paper tape cutting forming cutter 3, due to spring action, cutter recovers original position again. Pull the cut and formed paper tape into the clamping device 5, the structure of the clamping device 5 is shown in FIG. 9 . 29 is a spring c, 30 and 32 are clamping blocks, which are placed in the fixed seat 33 . The clamping block a30 can move along the direction of the spring c29. The clamping block b32 also has the same structure. A clamping handle 31 with an eccentric structure is installed between the two clamping blocks. The structure is shown in Figure 11. Turn the clamping handle 31, The two clamping blocks can be opened. In operation first the clamping handle 31 is rotated and the clamping device 5 will open. Such clamping handle 31 and clamping device 5 respectively have the same set on the left and right sides of column 4 . Since the paper tape has been cut into a T shape, the paper tape and the viscose fiber are clamped at the clamping device 5, and the specific structure is shown in FIG. 9 . In Fig. 12, 36 is the paper tape that has been cut into a T shape, and 38 is a bundled sticky fiber. One end of the T-shaped part of the paper tape, that is, the left part 35 of the paper tape, is clamped by two clamping blocks 30, 32 together with the sticky fiber. Clamp. The other end of the same paper tape is that the paper tape right part 37 is clamped by the other end clamping block. After clamping, turn the handle 7 to drive the coaxial toothed wheel 6 to rotate. The toothed wheel has been integrated with the fixed seat 33 of the pressing block through the crank and connecting rod mechanism, and is driven by the synchronous toothed belt 9 to drive the transmission shaft. The toothed wheel on 12 rotates, and the toothed wheel on the other side is driven by the toothed belt to rotate, because the transmission structure is 1:1, so it is guaranteed that the two sets of clamping devices 5 can rotate synchronously. After one rotation, the shading paper wraps the bundled viscose tightly, and the paper tape is cut off, thus completing the production of the viscose shading cover.

2. Refer to Figure 16 for bundled viscose fiber cutter

In order to form a clear image of the viscose fiber section on the CCD target surface, the viscose fiber section is required to be as smooth as possible. Therefore, the method of cutting the bundled viscose fiber is particularly important. The required shredding device is referring to Fig. 16, hereinafter referred to as shredder. Its effect is: put the bundled viscose fiber that has shading cover into slicer Fig. 13, make viscose fiber slice.

After clamping, the situation in the slot of the slicer is shown in the enlarged part of Figure 13, where 40 is the bundle Viscose. The external dimensions of the slicer and the slicer positioning device 47 just match, so that the slicer can just be put into the slicer positioning device 47, which is convenient for clamping and positioning. At the same time, a clamping and positioning device similar to the slicer positioning device 47 is also fixed on the microscope two-dimensional workbench Figure 18, so that fast clamping and positioning can be realized, and the position of the workbench can be avoided during each inspection.

The bundled viscose fiber cutter shown in FIG. 16 is mainly composed of a shredding device base 43 , upper and lower clamping mechanisms 46 and 51 , a slicer positioning device 47 , a slicer clamping device 48 , and a rotating shaft 50 .

3. Refer to Figure 19 for the lighting device

The illumination system determines the clarity of the acquired image, thus directly affecting the detection accuracy of the system. It is impossible for all the viscose fibers in the section to be kept vertical. When illuminated with a parallel light source, it is impossible for the light to pass through each viscose fiber uniformly, resulting in uneven brightness of the viscose fiber section; the image is not clear. After trial and error, a hemispherical light source was designed, see Figure 19. The light-emitting diodes 60 are closely arranged in three layers, one is placed in the center, and the light-emitting diodes between the layers are alternately placed and fixed in the hemispherical light source support 59 .

The two-dimensional translation guides adopt ball linear guides. The stereo microscope has a 9x objective magnification and uses very good aplanatic and aberrant, high-resolution objectives. Referring to Fig. 18, 53 is an illumination device referring to Fig. 19, 55 is a microscopic imaging objective lens, 56 is a CCD camera, and 58 is a computer for data processing.

5. Image acquisition and processing refer to Figures 20 and 21

Image acquisition and processing: the CCD image sensor is used to obtain the section image of the viscose fiber slice, and the acquired image information is sent to the computer. The computer processes the image information collected by it to obtain the number and shape information of viscose fibers.

The following methods are used for the counting and morphological analysis of viscose fiber bundles:

1 Using a 3×3 smoothing template, the image is smoothed four times, and then a linear stretching algorithm is used to enhance the image.

2 The system adopts an adaptive threshold segmentation method based on gradient operator. Rows and columns are processed separately to perform background removal on the image. The algorithm flow is shown in Figure 21. First, the gradient calculation is performed on the source image, and the gradient extremum is extracted. Then judge whether the extreme value is positive or negative. If the extreme value is positive, it will be stored in the positive array, otherwise it will be negative and stored in the negative array. Finally, the row or column background is eliminated according to the positive and negative values, and the global low-threshold segmentation is used after segmentation, so that the segmented image we need is obtained.

3. Separating the local adhesive part of the image after segmentation to ensure that the sections of each adhesive fiber are separated from each other, which provides convenience for counting.

When counting 4-section images, the image is first encoded with line segments, and then the single-point connected regions are identified and counted according to the region characteristic parameters.

5. After counting, carry out morphological calculation on each viscose fiber section, and distinguish and mark the viscose fiber with abnormal shape. In this way, the detection of the number of viscose fibers and the analysis of their morphology are completed, and the system has the functions of data storage and historical detection data query.

8. one kind is used for the image immediate processing method that boundling glues fine counting and fracture morphology analytical system, concrete treatment step:

Step 1 adopts 3 * 3 smooth template, to image smoothing four times, then adopts the linear stretch algorithm to come image is strengthened;

Step 2, system adopts the adaptive threshold dividing method based on gradient operator, and row and column is handled respectively, image is carried out background remove.At first source images is carried out gradient calculation, extract the gradient extreme value, then judge the positive and negative of extreme value, if extreme value deposits positive array in for just, otherwise for negative, deposit the negative group in, the positive negative value of last basis is carried out the elimination of row or column background.Cut apart the back and adopt the low threshold value of the overall situation to cut apart, so just obtained the split image that we need;

Step 3 is partly separated cutting apart back image local adhesion, guarantees that every sticking fine section is separated from one another, for counting is provided convenience;

Step 4, cross-section image when counting, at first image is carried out line drawing coding, differentiate the single-point connected region according to the provincial characteristics parameter then and count;

Step 5 after counting finishes, is carried out morphology to each sticking fine section and is calculated, and paramorph sticking fibre is differentiated and mark, has so just finished the analysis of sticking fine number detection and form thereof, and system has data storage and the historical data query function that detects.
