Description

Technical Field

[0001] The invention relates to the technical field of geological exploration research, and in particular to a thin slice debonding device and a control method. Background Art

[0002] Rocks are the direct carriers of various geological processes and the most direct and effective physical materials for studying various geological processes. Making collected rock samples into thin slices for microscopic observation is the most basic research method. Thin slice observation is also indispensable in shale gas exploration research. Since it is difficult to sample rock samples for deep shale gas, usually only very limited existing samples can be studied, which requires improving the reuse rate of rock samples. Thin slice degumming is a means to improve the reuse rate of rock samples. As the name suggests, it is to remove the gum wrapped on the rock slice for easy preservation and restore it to a clean and pure state, so that the rock slice that has been observed can be used as a research sample for other experiments.

[0003] However, after the existing thin-section degumming device degummed the rock thin sections, due to incomplete cleaning, the processed rock thin sections could not meet many advanced experimental requirements, such as the inclusion laser Raman experiment. The Canada gum remaining on the thin sections has fluorescent characteristics, which will have a serious impact on the inclusion laser Raman experiment. Therefore, the thin-section degumming treatment that meets the requirements of advanced experiments is now manually operated, but the degumming liquid used in the degumming process is an organic solvent, which is often highly volatile and weakly toxic, posing an experimental safety risk to the experimenters; and due to the strong volatility of the degumming liquid, in order to avoid experimental accidents, it is often carried out at room temperature, resulting in a lengthy degumming process and slow experimental speed; in addition, the thickness of rock thin sections is generally 0.1mm, which is not easy to preserve.

In addition, in the embodiment of the present invention, in order to facilitate the observation of the processing conditions in the sample bin 2, the sealing cover 26 has a transparent visual area made of a glass plate.

[0054] Combination Figure 1 and Figure 4 As shown, the thin-sheet degumming device of the present invention heats the processing liquid in multiple processing chambers 11 by arranging multiple heating structures 12, thereby facilitating improving the processing rate and processing effect.

[0055] Specifically, the number of heating structures 12 is not specifically limited, and one processing chamber 11 is correspondingly provided with at least one heating structure 12. The heating structure 12 includes, but is not limited to, an electromagnetic heating structure. In some embodiments of the present invention, a plurality of heating structures 12 are installed one-to-one under a plurality of processing chambers 11, so that the heating structure 12 will not contact with the processing liquid and affect its service life. Optionally, the heating structure 12 can also be arranged in the wall of the processing chamber 11 or laid on the outer wall surface of the processing chamber 11. In addition, in order for the control mechanism 4 to better control the heating structure 12 for heating, a temperature detection structure 14 is provided in the processing chamber 11, and the control mechanism 4 is electrically connected to the temperature detection structure 14 and can control the heating temperature of the heating structure 12 according to the detection signal of the temperature detection structure 14.

[0056] Combination Figure 1 and Figure 5 As shown, the slice degumming device of the present invention collects images 7 of sample slices in multiple sample chambers 2 by setting multiple image acquisition structures 13, so that the control mechanism 4 can analyze the status of the sample slice 6 according to the image 7 of the sample slice. On the one hand, it can judge whether the degumming is completed according to the image during the degumming process. On the other hand, it can also collect the image of the sample slice 6 during the process of cleaning the sample slice 6 after the degumming is completed, and then judge whether the cleaning is completed according to the image changes outside the edge of the sample in the image, thereby improving the degree of automation of the device and avoiding damage to the sample 61 caused by frequent manual operations.

[0057] Specifically, the number of image acquisition structures 13 is not specifically limited, and one processing chamber 11 is corresponding to at least one image acquisition structure 13. The image acquisition structure 13 includes but is not limited to an image sensor. The control mechanism 4 includes a control module 41 installed on the device body 1, and the control module 41 is electrically connected to the image acquisition structure 13, the heating structure 12 and the temperature detection structure 14 respectively. In addition, the control mechanism 4 also includes an analysis and processing module and a communication interface 43 and a power interface 42 provided on the device body 1. The control module 41 is electrically connected to the analysis and processing module via the communication interface 43, and the control module 41 is electrically connected to the external power supply via the power interface 42. Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the top surface of the sample chamber 2 has a placement opening 28 for placing the sample slice 6 into the sample cavity 21, and the image acquisition structure 13 is installed in the processing chamber 11 and is located above the placement opening 28. The liquid level of the processing liquid in the processing chamber 11 is lower than the height of the image acquisition structure 13. In the embodiment of the present invention, in order to facilitate the observation of the degumming treatment of the sample slice 6, the top surface of the processing chamber 11 is provided with an observation window 116. Optionally, the image acquisition structure 13 can also be installed above the observation window 116.

[0058] The working process of the thin slice degumming device of the present invention includes: first injecting the degumming liquid into the processing chamber 11, so that the degumming liquid flows into the sample chamber 2 to perform degumming treatment on the sample thin slice 6; collecting an image 7 of the sample thin slice (defined as a degumming image); obtaining the colloid edge and the sample edge of the degumming image; judging whether the sample thin slice 6 has completed degumming according to the changes of the colloid edge and the sample edge of the degumming image.

[0059] Specifically, before depolymerization, the colloid 62 of the sample slice 6 is dyed so that the collected depolymerized image is a color image with multiple pixel points 73, so as to better obtain the colloid edge and sample edge of the depolymerized image, wherein the image 7 of the sample slice includes a sample image 71 and a colloid image 72, the colloid edge is the edge of the colloid image 72, and the sample edge is the edge of the sample image 71; then the color image of the depolymerized image is first processed into a grayscale depolymerized image; then the grayscale value and coordinates of each pixel point 73 of the grayscale depolymerized image are determined; then according to the grayscale value and coordinates of each pixel point 73, the low threshold and high threshold of the grayscale value are determined; the coordinates of the pixel point 73 in the grayscale depolymerized image whose grayscale value is greater than the low threshold and less than the high threshold are extracted, and recorded as the coordinates of the colloid edge of the grayscale depolymerized image; the coordinates of the pixel point 73 in the grayscale depolymerized image whose grayscale value is greater than or equal to the high threshold are extracted, and recorded as the coordinates of the sample edge of the grayscale depolymerized image. Furthermore, the difference between the initial coordinates and the current coordinates of each pixel point 73 at the colloid edge of the grayscale depolymerized image is calculated, and recorded as the coordinate change value of the colloid edge of the grayscale depolymerized image; the difference between the initial coordinates and the current coordinates of each pixel point 73 at the sample edge of the grayscale depolymerized image is calculated, and recorded as the coordinate change value of the sample edge of the grayscale depolymerized image; until the coordinate change value of the colloid edge of the grayscale depolymerized image and the coordinate change value of the sample edge of the grayscale depolymerized image both meet the preset conditions, it is determined that the sample slice 6 has completed depolymerization.

[0060] The gray value c of pixel 73 is: c = R*m r +G*m g +B*m b ; Wherein, R is the red value of the pixel point 73 in the RGB mode, G is the green value of the pixel point 73 in the RGB mode, B is the blue value of the pixel point 73 in the RGB mode, m r is the weighting coefficient corresponding to the red value, m g is the weighting coefficient corresponding to the green value, m bis the weighting coefficient corresponding to the blue value; the coordinates of the pixel point 73 include a horizontal coordinate a and a vertical coordinate b; therefore, the coordinates and grayscale values ​​corresponding to each pixel point 73 are expressed as (a, b, c), and the coordinates and grayscale values ​​corresponding to each pixel point 73 are stored in a matrix and recorded as an image data matrix P; then, by traversing the image data matrix P according to a preset segmentation path, the horizontal coordinate and vertical coordinate of the traversed image data are reduced in dimension and only one is saved, expressed as (a, c) or (b, c), and then the horizontal coordinate or vertical coordinate of each pixel point 73 is arranged and drawn as shown in Figure 7 The histogram of the grayscale values ​​of each pixel point 73 shown in the figure is used to determine the high threshold value k and the low threshold value j; in this embodiment, the preset segmentation paths include the segmentation path A-A' and the segmentation path B-B' arranged along the two diagonals, the segmentation path C-C' arranged along the horizontal midline, and the segmentation path D-D' arranged along the longitudinal midline; finally, the coordinates of the pixel points 73 whose grayscale values ​​are greater than the low threshold value j and less than the high threshold value k are extracted and recorded as the coordinates of the colloid edge; the coordinates of the pixel points 73 whose grayscale values ​​are greater than or equal to the high threshold value k are extracted and recorded as the coordinates of the sample edge; wherein, when the gel dissolution starts, the initial coordinates of each pixel point 73 at the edge of the colloid are stored in a matrix and recorded as the coordinates of the colloid edge. Coordinate data matrix E0, the initial coordinates of each pixel point 73 at the edge of the sample are stored in a matrix and recorded as the coordinate data matrix F0 of the edge of the sample; during the degumming process, the current coordinates of each pixel point 73 at the edge of the colloid are stored in a matrix and recorded as the coordinate data matrix E of the edge of the colloid, and the current coordinates of each pixel point 73 at the edge of the sample are stored in a matrix and recorded as the coordinate data matrix F of the edge of the sample; therefore, the coordinate change value ΔE of the edge of the colloid is E-E0, and the coordinate change value ΔF of the edge of the sample is F-F0; thereby, by monitoring whether the coordinate change value ΔE of the edge of the colloid and the coordinate change value ΔF of the edge of the sample meet the preset conditions, it can be determined whether the sample sheet 6 has completed degumming.

[0061] Combination Figure 1 , Figure 8 and Fig. 9As shown, the working process of the slice degumming device of the present invention also includes: when it is determined that the sample slice 6 has completed degumming, the degumming liquid in the processing chamber 11 is discharged, and the cleaning liquid is injected into the processing chamber 11, so that the cleaning liquid flows into the sample chamber 2 to clean the sample 61; the image 7 of the sample slice 6 is collected (defined as the cleaning image); the cleaning image is processed into a grayscale cleaning image; the grayscale value and coordinates of each pixel point of the grayscale cleaning image are determined; the coordinates of the pixel points whose grayscale value is greater than or equal to the high threshold in the grayscale cleaning image are extracted, and recorded as the coordinates of the sample edge in the grayscale cleaning image, that is, the coordinates of the sample edge in the grayscale cleaning image, which are the same as the above-mentioned degumming control The working principle involved in obtaining the sample edge in the grayscale degummed image during the process is the same, so the high threshold k determined in the degumming process can be used to determine the coordinates of the sample edge in the grayscale cleaned image. Since the colloid is dissolved and broken by the degumming liquid, there is no need to obtain the colloid edge in the grayscale cleaned image during the cleaning process; according to the coordinates of the sample edge in the grayscale cleaned image, the grayscale background image located outside the sample edge in the grayscale cleaned image is obtained; the grayscale value of each pixel point of the grayscale background image is determined; if the grayscale value of each pixel point of the grayscale background image is less than or equal to the low threshold j, it is judged that the sample slice 6 has completed cleaning.

[0062] Combination Figure 5 and Figure 6 As shown, after the sample slice 6 is debonded, the colloid 62 is dissolved and broken by the debonding liquid, and a part of the dissolved and broken colloid 62 is carried away by the debonding liquid, while another part adheres to the surface of the sample slide 63. Therefore, when this part of the dissolved colloid 62 is removed by the flow of the cleaning liquid, the grayscale of the image outside the sample 61 can be changed, so that it can be judged whether the sample slice 6 has been cleaned according to the change of the grayscale background image.

The control mechanism 4 is electrically connected to the indicating structure 15 and can control the start indicator light 151 and the stop indicator light 152 to turn on and off respectively. During the process from the start of dissolution to the completion of cleaning, the start indicator light 151 turns on and the stop indicator light 152 turns off; after the cleaning is completed, the start indicator light 151 turns off and the stop indicator light 152 turns on, thereby reminding the experimenter not to take out the sample chamber 2 during the process from the start of dissolution to the completion of cleaning, and to take out the sample chamber 2 after the cleaning is completed to take out the dissolution sample slice 6.

The lifting screw has a coarse thread section that is threadedly matched with the coarse adjustment roller 321 and a fine thread section that is threadedly matched with the fine adjustment roller 322. The pitch of the coarse thread section is greater than the pitch of the fine thread section. Therefore, the adjustment amount of the device body 1 driven to rise and fall by one circle of the coarse adjustment roller 321 is greater than the adjustment amount of the device body 1 driven to rise and fall by one circle of the fine adjustment roller 322. The outer diameter of the coarse adjustment roller 321 is greater than the outer diameter of the fine adjustment roller 322 for easy identification. The number and arrangement of the lifting support structures 32 are not specifically limited.

[0070] Implementation Method 2

[0071] Combination Figures 1 to 4 As shown, the present invention also provides a control method for thin slice disintegration, which is used to control the thin slice disintegration device. The thin slice disintegration device in this embodiment has the same specific structure, working principle and beneficial effects as the thin slice disintegration device in embodiment 1. The control method in this embodiment can be implemented with reference to the thin slice disintegration device in embodiment 1, and will not be repeated here.

[0072] Combination Figures 5 to 8 As shown, the control method of the present invention includes the following steps: injecting a degumming liquid into the processing chamber 11, so that the degumming liquid flows into the sample chamber 2 to perform a degumming treatment on the sample slice 6; wherein the sample slice 6 includes a sample 61 and a colloid 62 wrapped outside the sample 61; collecting a degumming image of the sample slice 6; obtaining the colloid edge and the sample edge of the degumming image; judging whether the sample slice 6 has completed degumming according to the changes of the colloid edge and the sample edge of the degumming image.

[0073] In an embodiment of the present invention, the control method further includes: before degumming, dyeing the colloid 62 of the sample slice 6; the degummed image is a color image with multiple pixel points 73; obtaining the colloid edge and sample edge of the degummed image, including the following steps: processing the color image into a grayscale degummed image; determining the grayscale value and coordinates of each pixel point 73 of the grayscale degummed image; arranging the grayscale values ​​of each pixel point 73 of the grayscale degummed image according to their coordinates, and determining the low threshold and high threshold of the grayscale value; extracting the coordinates of the pixel point 73 in the grayscale degummed image whose grayscale value is greater than the low threshold and less than the high threshold, and recording them as the coordinates of the colloid edge of the grayscale degummed image; extracting the coordinates of the pixel point 73 in the grayscale degummed image whose grayscale value is greater than or equal to the high threshold, and recording them as the coordinates of the sample edge of the grayscale degummed image;

[0074] In an embodiment of the present invention, whether the sample slice 6 has completed the degumming is determined based on the changes in the colloid edge and the sample edge of the degumming image; the following steps are included: calculating the difference between the initial coordinates and the current coordinates of the colloid edge, and recording it as the coordinate change value of the colloid edge; calculating the difference between the initial coordinates and the current coordinates of the sample edge, and recording it as the coordinate change value of the sample edge; until the coordinate change value of the colloid edge and the coordinate change value of the sample edge both meet the preset conditions, it is determined that the sample slice 6 has completed the degumming.

[0075] Combination Figure 8 and Fig. 9 As shown, in an embodiment of the present invention, the control method further includes the following steps: when it is determined that the sample slice 6 has completed degumming, the degumming liquid in the processing chamber 11 is discharged, and the cleaning liquid is injected into the processing chamber 11, so that the cleaning liquid flows into the sample chamber 2 to clean the sample 61; a cleaning image of the sample slice 6 is collected; the cleaning image is processed into a grayscale cleaning image; the grayscale value and coordinates of each pixel point of the grayscale cleaning image are determined; the coordinates of the pixel points whose grayscale values ​​are greater than or equal to the high threshold in the grayscale cleaning image are extracted, and recorded as the coordinates of the sample edge in the grayscale cleaning image, which is the same as the working principle involved in obtaining the sample edge in the grayscale degumming image in the above-mentioned degumming control process. Therefore, the high threshold determined in the degumming control process can be used to determine the coordinates of the sample edge in the grayscale cleaning image. Since the colloid is dissolved and broken by the degumming liquid, there is no need to obtain the colloid edge in the grayscale cleaning image during the cleaning process; according to the coordinates of the sample edge in the grayscale cleaning image, a grayscale background image located outside the sample edge in the grayscale cleaning image is obtained; according to the change of the grayscale background image, whether the sample slice 6 has completed cleaning is determined.

[0076] In the embodiment of the present invention, judging whether the sample slice has been cleaned according to the change of the background image in the cleaning image includes the following steps: determining the grayscale value of each pixel of the grayscale background image; if the grayscale value of each pixel of the grayscale background image is less than or equal to the low threshold, judging that the sample slice 6 has been cleaned. That is to say, in the cleaning control process, the low threshold determined in the dissolution control process can be used to analyze whether there is a broken colloid image in the grayscale background image. When the grayscale value of each pixel of the grayscale background image is less than or equal to the low threshold, it means that there is no broken colloid image in the grayscale background image, and therefore, the colloid on the sample slice 6 is cleaned and the sample slice 6 has been cleaned.
