[0018] A method for using a scanning device for pathological section detection is as follows:

[0019] Step 1: Drive the Y-axis driving component and the lifting plate to move to the upper side of the glass slide on the workbench through starting the X-axis driving component;

[0020] Step 2: Start the first hydraulic cylinder and the second hydraulic cylinder to correct and fix the glass slide on the clamping plate;

[0021] Step 3: Start the hydraulic cylinder 3 to drive the cleaning strips on both sides to pass through the upper and lower ends of the contact glass slide, and sweep the dust and impurities on the upper and lower surfaces of the glass slide.

[0022] Step 4: Due to the intermittent blocking of the inclined block by the convex block plate, the strip plate and the cleaning strip will be driven to slide on the connecting strip, so that when the cleaning strip moves to the left, it will also move back and forth in a small amplitude.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. In the present invention, by starting the X-axis drive assembly to drive the Y-axis drive assembly and the lifting plate to move to the upper side of the glass slide on the workbench, then starting the Y-axis drive assembly to drive the lifting plate to descend, the lifting plate drives the clamping plates on both sides to descend synchronously, so that the clamping plates on both sides are located at the front and rear sides of the glass slide, stop the Y-axis drive assembly, start the hydraulic cylinder 1 to drive the rear clamping plate and the rack fixed thereto to move forward, drive the gear shaft to rotate, and the gear shaft drives the front clamping plate and the rack fixed thereto to move backward, so that the clamping plates on both sides are in a relative motion state, and the clamping plates on both sides drive the correction plates on both sides to move relatively synchronously, so that the front and rear ends of the glass slide are located above the inner bottom ends of the clamping plates. The hydraulic cylinder 1 stops working, and then start the Y-axis drive assembly to drive the lifting plate and the clamping plates to rise. At this time, the front and rear ends of the glass slide will gradually contact the clamping plates and be driven upward by the clamping plates, and the glass slide will be separated from the workbench. Start the hydraulic cylinder 2 to drive the correction plates on both sides to descend synchronously, and the correction plates will drive the top strip to descend synchronously. The top strip pushes the spherical rod on both sides to approach each other through magnetic repulsion, and the spherical balls on the side where the spherical rods approach each other will push the correction piece to slide obliquely upward on the clamping plate, stretching the spring 2. The provided correction piece will push both sides of the glass slide so that the glass slide is located at the center of the clamping plate, which is convenient for correcting the position of the glass slide left and right, preventing the position of the glass slide from being skewed during the clamping process of the glass slide, resulting in affecting the subsequent pathological scanning effect, and improving the pathological scanning quality of the section.

[0025] 2. In the present invention, start the hydraulic cylinder 1 to drive the clamping plates on both sides to approach each other, so that the front and rear ends of the glass slide are abutted against the correction plates, and stop the hydraulic cylinder 1 from working, which is convenient for correcting the front and rear ends of the glass slide, so that the glass slide can be exactly located below the through hole on the lifting plate, facilitating subsequent detection and scanning, thereby improving the scanning quality. At the same time, the provided rack and gear shaft enable the clamping plates on both sides to move in a unified and coordinated manner, ensuring that the position of the glass slide can be corrected smoothly.

[0026] 3. In the present invention, as the second hydraulic cylinder starts and the correction plate continues to descend, it will drive the guide rod and the movable plate to continue descending, so that the lower end of the movable plate presses and adheres the corrected glass slide onto the clamping plate, preventing the corrected glass slide from shifting during the movement process and ensuring the accuracy of subsequent detection of the glass slide. The provided first spring and guide rod can adaptively buffer the downward pressure of the movable plate, avoiding excessive downward pressure of the correction plate and causing the glass slide to break.

[0027] 4. In the present invention, starting the third hydraulic cylinder drives the fixed strip, connecting strip, cleaning strip, and strip plate to move synchronously towards the direction of the fixed glass slide. The cleaning strips on both sides will pass through the upper and lower ends of the contacted glass slide. The cleaning strip is made of a flexible and self-adaptive deformation material. The provided cleaning strip facilitates the removal of dust and impurities on the upper and lower surfaces of the glass slide, ensuring the accuracy of subsequent detection scanning.

[0028] 5. In the present invention, when the strip plate moves, it will also drive the inclined block to move synchronously. The inclined block is intermittently blocked by the convex block plate, which will drive the strip plate and the cleaning strip to slide on the connecting strip, compressing the third spring. When the cleaning strip moves to the left, it will also move back and forth slightly in the front and rear directions, thereby improving the cleaning quality of the dust and impurities on the surface of the glass slide and ensuring the subsequent detection quality.

[0029] 6. In the present invention, pushing the limit plate to compress the fourth spring to separate the limit plate from the connecting strip can directly disassemble the connecting strip and the cleaning strip from the fixed strip. The loading and unloading are relatively convenient, and the cleaning strip can be replaced and cleaned, improving the service quality of the cleaning strip. BRIEF DESCRIPTION OF THE DRAWINGS

An X-axis driving assembly 2 is provided at the upper end of the workbench 1, and a Y-axis driving assembly 3 is provided on the left side of the upper end of the X-axis driving assembly 2; a clamping mechanism for clamping the glass slide on the workbench 1 is also provided. The clamping mechanism includes a lifting plate 4 slidably arranged on the Y-axis driving assembly 3, and a through hole is opened on the front side of the lifting plate 4; at the through hole at the lower end of the lifting plate 4, clamping plates 5 are symmetrically and slidably installed in the front and rear. A rack 6 is fixedly installed at the right end of each of the two clamping plates 5, and a gear shaft 7 is meshed between the racks 6. The upper end of the gear shaft 7 is rotatably installed on the lifting plate 4. A hydraulic cylinder 8 is fixedly installed at the rear end of the rear clamping plate 5, and the middle of the hydraulic cylinder 8 is fixedly connected to the lifting plate 4. A correction plate 9 is slidably installed through the middle of each of the clamping plates 5, and a hydraulic cylinder 10 is fixedly installed at the lower end of each of the correction plates 9. The lower end of the hydraulic cylinder 10 is fixedly connected to the clamping plate 5. A movable plate 11 is slidably installed at one end of each of the correction plates 9 close to each other. A guide rod 12 is fixedly installed in the middle of the upper end of the movable plate 11. The upper end of the guide rod 12 is slidably installed through the correction plate 9. A first spring 13 is sleeved on the outer side of the guide rod 12. The upper and lower ends of the first spring 13 are respectively fixedly connected to the correction plate 9 and the movable plate 11. Correction pieces 14 are symmetrically and slidably installed on the left and right sides of one end of each of the clamping plates 5 close to each other, and an inclined chute is provided on the clamping plate 5 corresponding to the correction piece 14. A second spring 15 is fixedly installed at one end of each of the correction pieces 14, and the other end of the second spring 15 is fixedly connected to the clamping plate 5. A spherical rod 16 is abutted and attached to one end of each of the correction pieces 14 away from each other. A vertical plate 17 is slidably installed through the middle of the spherical rod 16. One end of the vertical plate 17 is fixedly connected to the clamping plate 5. A top bar 18 is provided on the upper side of each of the spherical rods 16. The upper end of the top bar 18 is fixedly connected to the correction plate 9. The inclination angle between the spherical rod 16 and the vertical plate 17 is the same as the sliding inclination angle between the correction piece 14 and the clamping plate 5. Repulsive magnets are provided inside both the top bar 18 and the spherical rod 16;

[0049] During operation, the X-axis drive assembly 2 is started to drive the Y-axis drive assembly 3 and the lifting plate 4 to move to the upper side of the glass slide on the workbench 1. Then, the Y-axis drive assembly 3 is started to drive the lifting plate 4 to descend. The lifting plate 4 drives the clamping plates 5 on both sides to descend synchronously, so that the clamping plates 5 on both sides are located at the front and rear sides of the glass slide. The Y-axis drive assembly 3 is stopped. The hydraulic cylinder 8 is started to drive the rear clamping plate 5 and the rack 6 fixed thereto to move forward, driving the gear shaft 7 to rotate. The gear shaft 7 drives the front clamping plate 5 and the rack 6 fixed thereto to move backward, making the clamping plates 5 on both sides in a relative motion state. The clamping plates 5 on both sides drive the correction plates 9 on both sides to move relatively synchronously, so that the front and rear ends of the glass slide are located on the upper side of the inner bottom ends of the clamping plates 5. The hydraulic cylinder 8 stops working. Then, the Y-axis drive assembly 3 is started to drive the lifting plate 4 and the clamping plates 5 to rise. At this time, the front and rear ends of the glass slide will gradually come into contact with the clamping plates 5 and be driven upward by the clamping plates 5, and the glass slide will be separated from the workbench 1. The hydraulic cylinder 10 is started to drive the correction plates 9 on both sides to descend synchronously. The correction plates 9 will drive the top bar 18 to descend synchronously. The top bar 18 pushes the spherical rod 16 on both sides to approach each other through magnetic repulsion. The spherical balls on the side where the spherical rod 16 approaches each other will push the correction piece 14 to slide obliquely upward on the clamping plate 5, stretching the second spring 15. The provided correction piece 14 will push both sides of the glass slide to make the glass slide located at the center of the clamping plate 5, facilitating the left-right correction of the position of the glass slide, preventing the position of the glass slide from being skewed during the clamping process of the glass slide, resulting in affecting the subsequent pathological scanning effect, and improving the pathological scanning quality of the section. Then, the hydraulic cylinder 8 is started to drive the clamping plates 5 on both sides to approach each other, so that the front and rear ends of the glass slide are in contact with the correction plates 9. The hydraulic cylinder 8 stops working, facilitating the correction of the front and rear ends of the glass slide, making the glass slide exactly located at the lower side of the through hole on the lifting plate 4, facilitating subsequent detection and scanning, and thus improving the scanning quality. At the same time, the provided rack 6 and gear shaft 7 enable the clamping plates 5 on both sides to move in a unified and coordinated manner, ensuring that the position of the glass slide can be corrected smoothly. As the hydraulic cylinder 10 continues to descend with the correction plate 9, it will drive the guide rod 12 and the movable plate 11 to continue to descend, so that the lower end of the movable plate 11 presses the corrected glass slide against the clamping plate 5, avoiding the situation that the corrected glass slide is offset during the movement process, ensuring the accuracy of the subsequent detection of the glass slide. The provided first spring 13 and guide rod 12 can adaptively buffer the downward pressure of the movable plate 11, avoiding excessive downward pressure of the correction plate 9, resulting in the fragmentation of the glass slide.

[0050] As an embodiment of the present invention, a cleaning mechanism is further provided for cleaning dust or residues on the surface of the glass slide after clamping. The cleaning mechanism includes two cleaning strips 19 symmetrically arranged up and down on the right side of the clamping plate 5. At the front sides of the mutually remote ends of the cleaning strips 19, connecting strips 20 are slidably installed. At the right ends of the connecting strips 20, fixing strips 201 are provided, and the fixing strips 201 are fixedly connected to the lifting plate 4. At the left ends of the fixing strips 201, hydraulic cylinders three 21 are fixedly installed, and the hydraulic cylinders three 21 are fixedly connected to the front end of the lifting plate 4. At the front ends of the connecting strips 20, springs three 22 are fixedly installed, and at the front ends of the springs three 22, strip plates 23 are fixedly installed. The mutually approaching ends of the strip plates 23 are respectively fixedly connected to the two cleaning strips 19. At the right sides of the front ends of the strip plates 23, inclined blocks 24 are fixedly installed, and at the front sides of the inclined blocks 24, convex block plates 25 are provided, and the convex block plates 25 are fixedly connected to the right end of the lifting plate 4. At the mutually remote ends of the fixing strips 201 corresponding to the connecting strips 20, positioning rods 26 are fixedly installed, and the positioning rods 26 are slidably installed through the connecting strips 20. At the left sides of the mutually remote ends of the fixing strips 201, limiting plates 27 are slidably installed, the left sides of the limiting plates 27 are abutted against the connecting strips 20, at the right ends of the limiting plates 27, springs four 28 are fixedly installed, and at the right ends of the springs four 28, connecting plates 29 are fixedly installed, and the mutually approaching ends of the connecting plates 29 are fixedly installed on the fixing strips 201;

[0051] During operation, after clamping, the hydraulic cylinder three 21 is started to drive the fixing strip 201, the connecting strip 20, the cleaning strip 19 and the strip plate 23 to move synchronously towards the fixed glass slide. The two cleaning strips 19 will pass through the upper and lower ends of the glass slide in contact. The cleaning strip 19 is made of a flexible and self-adaptive deformation material. The provided cleaning strip 19 is convenient for sweeping away dust and impurities on the upper and lower surfaces of the glass slide, ensuring the accuracy of subsequent detection and scanning. When the strip plate 23 moves, it will also drive the inclined block 24 to move synchronously. The inclined block 24 is intermittently blocked by the convex block plate 25, which will drive the strip plate 23 and the cleaning strip 19 to slide on the connecting strip 20, compressing the spring three 22. When the cleaning strip 19 moves to the left, it will also move back and forth slightly in the front and back directions, thereby improving the cleaning quality of the dust and impurities on the surface of the glass slide, and thus ensuring the subsequent detection quality. The limiting plate 27 is pushed to compress the spring four 28, so that the limiting plate 27 is separated from the connecting strip 20, and the connecting strip 20 and the cleaning strip 19 can be directly detached from the fixing strip 201. The loading and unloading are both relatively convenient, and the cleaning strip 19 can be replaced and cleaned, improving the service quality of the cleaning strip 19.

[0052] A method for using a scanning device for pathological section detection is as follows:

[0053] Step 1: By starting the X-axis driving component 2, drive the Y-axis driving component 3 and the lifting plate 4 to move to the upper side of the glass slide on the workbench 1;

[0054] Step 2: Start hydraulic cylinder 1 8 and hydraulic cylinder 2 10 to correct and fix the glass slide on the clamping plate 5;

[0055] Step 3: Start hydraulic cylinder 3 21 to drive the cleaning strips 19 on both sides to pass through the upper and lower ends of the glass slide in contact with the glass slide, and sweep away the dust and impurities on the upper and lower surfaces of the glass slide;

[0056] Step 4: Due to the intermittent block of the inclined block 24 by the convex block plate 25, the strip plate 23 and the cleaning strip 19 will slide on the connecting strip 20, so that when the cleaning strip 19 moves to the left, it will also move back and forth in a small amplitude.

[0057] Working principle:

[0058] When the present invention is in use, the X-axis driving component 2 is started to drive the Y-axis driving component 3 and the lifting plate 4 to move to the upper side of the glass slide on the workbench 1. Then, the Y-axis driving component 3 is started to drive the lifting plate 4 to descend. The lifting plate 4 drives the clamping plates 5 on both sides to descend synchronously, so that the clamping plates 5 on both sides are located at the front and rear sides of the glass slide. The Y-axis driving component 3 is stopped, and the hydraulic cylinder 1 8 is started to drive the clamping plate 5 at the rear side and the rack 6 fixed thereto to move forward, driving the gear shaft 7 to rotate. The gear shaft 7 drives the clamping plate 5 at the front side and the rack 6 fixed thereto to move backward, so that the clamping plates 5 on both sides are in a relative motion state. The clamping plates 5 on both sides drive the correction plates 9 on both sides to move relatively synchronously, so that the front and rear ends of the glass slide are located above the inner bottom ends of the clamping plates 5. The hydraulic cylinder 1 8 stops working. Then, the Y-axis driving component 3 is started to drive the lifting plate 4 and the clamping plates 5 to rise. At this time, the front and rear ends of the glass slide will gradually come into contact with the clamping plates 5 and be driven upward by the clamping plates 5, and the glass slide will be separated from the workbench 1. The hydraulic cylinder 2 10 is started to drive the correction plates 9 on both sides to descend synchronously. The correction plates 9 will drive the top bar 18 to descend synchronously. The top bar 18 pushes the spherical rod 16 on both sides to approach each other through magnetic repulsion. The spherical balls on the side where the spherical rod 16 approaches each other will push the correction piece 14 to slide obliquely upward on the clamping plate 5, stretching the spring two 15. The provided correction piece 14 will push both sides of the glass slide to make the glass slide located at the center of the clamping plate 5, facilitating the left-right correction of the position of the glass slide, preventing the position of the glass slide from being skewed during the clamping process of the glass slide, resulting in affecting the subsequent pathological scanning effect, and improving the pathological scanning quality of the section. Then, the hydraulic cylinder 1 8 is started to drive the clamping plates 5 on both sides to approach each other, so that the front and rear ends of the glass slide are abutted against the correction plates 9. The hydraulic cylinder 1 8 stops working, facilitating the correction of the front and rear ends of the glass slide, so that the glass slide can be exactly located below the through hole on the lifting plate 4, facilitating the subsequent detection and scanning, thereby improving the scanning quality. At the same time, the provided rack 6 and gear shaft 7 enable the clamping plates 5 on both sides to move in a unified and coordinated manner, ensuring that the position of the glass slide can be corrected smoothly. As the correction plate 9 continues to descend when the hydraulic cylinder 2 10 is started, it will drive the guide rod 12 and the movable plate 11 to continue to descend, so that the lower end of the movable plate 11 presses the corrected glass slide against the clamping plate 5, avoiding the situation that the corrected glass slide is offset during the movement process, and ensuring the accuracy of the subsequent detection of the glass slide. The provided spring one 13 and guide rod 12 can adaptively buffer the downward pressure of the movable plate 11, avoiding excessive downward pressure of the correction plate 9, resulting in the fragmentation of the glass slide. After the clamping is completed, the hydraulic cylinder 3 21 is started to drive the fixed strip 201, the connecting strip 20, the cleaning strip 19 and the strip plate 23 to move synchronously in the direction of the fixed glass slide. The cleaning strips 19 on both sides will pass through the upper and lower ends of the contacted glass slide. The cleaning strip 19 is made of a flexible and self-adaptive deformation material. The provided cleaning strip 19 is convenient for removing dust and impurities on the upper and lower surfaces of the glass slide, ensuring the accuracy of the subsequent detection and scanning. When the strip plate 23 moves, it will also drive the inclined block 24 to move synchronously. The inclined block 24 is intermittently blocked by the convex block plate 25.It will drive the strip plate 23 and the cleaning strip 19 to slide on the connecting strip 20, compressing the third spring 22. When the cleaning strip 19 moves to the left, it will also move back and forth in a small amplitude, thereby improving the cleaning quality of dust and impurities on the surface of the glass slide, ensuring the subsequent detection quality. Push the limit plate 27 to compress the fourth spring 28, so that the limit plate 27 is separated from the connecting strip 20, and the connecting strip 20 and the cleaning strip 19 can be directly detached from the fixing strip 201. The loading and unloading are relatively convenient, and the cleaning strip 19 can be replaced and cleaned, improving the service quality of the cleaning strip 19.

[0059] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
