Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical image processing, and in particular to a glass slide clamping mechanism. Background Technology
[0002] In the field of medical image processing, automated cell imaging systems, as core equipment, undertake crucial tasks such as cell morphology observation, quantity statistics, and pathological feature analysis. Their imaging efficiency and quality directly affect the accuracy of research conclusions and the reliability of clinical diagnoses. Currently, most automated cell imaging systems on the market rely on traditional motion platform structures to achieve slide positioning and movement. These motion platforms typically use mechanical grippers or vacuum adsorption to fix the slide, and then a motor drives a guide rail to move the slide along the X and Y axes, thereby achieving point-by-point imaging of cells in different areas of the slide.
[0003] However, traditional automated cell imaging systems suffer from stability and safety issues in slide fixation and movement. If mechanical grippers are used, the pressure is difficult to control precisely: too low a pressure can cause the slide to loosen or shift due to vibration or inertia during movement, leading to misalignment between the imaging area and the preset area, resulting in blurred or ghosted cell images that affect subsequent image analysis; too high a pressure can directly cause physical damage to the slide, such as cracks or edge breakage. Damaged slides not only render samples unusable but also pose a risk of cross-contamination. While vacuum adsorption fixation avoids the pressure damage from mechanical grippers, the vacuum system is susceptible to environmental humidity and the flatness of the slide surface. The presence of tiny air bubbles or dirt on the slide surface significantly reduces the adsorption force, also causing the slide to loosen during movement and compromising imaging stability.
[0004] Therefore, a new technical solution is needed to address the problem in existing automated cell imaging systems where slides are easily loosened and result in poor imaging quality when the slides are fixed and moved by a motion platform. Utility Model Content

[0007] A fixing member is provided on the path of the slide mounting plate to receive the slide sample. A connecting member is fixedly connected to one end of the slide mounting plate near the slide groove. The distance between the connecting member and the fixing member is less than the forward distance of the slide mounting plate. After the connecting member and the fixing member abut against each other, the fixing member applies a force to the slide pressure plate away from the direction of the slide sample.

Detailed Implementation
[0026] The present invention will be further described in detail below with reference to specific embodiments:
[0027] like Figure 1 and Figure 2As shown, a slide clamping mechanism is mounted on a substrate. The substrate is provided with a drive structure X-axis module 12 and Y-axis module 13. The Y-axis module 13 is movably mounted on the X-axis slide rail. A support plate 14 is mounted on the substrate. The end of the Y-axis module 13 away from the X-axis module 12 is slidably connected to the support plate 14. In at least one embodiment, the X-axis module 12 and Y-axis module 13 used in this invention are linear modules. By adjusting the position of the slide clamping module 2 through the X-axis module 12 and Y-axis module 13, the slide clamping module 2 can be moved to both the position for receiving the slide sample 3 and the position required to complete the focusing of the slide sample 3. This improves the matching accuracy between the moving position and the scanning path set by the software, thereby improving the accuracy of image stitching and realizing a large-range, high-precision movement of the slide sample 3.
[0028] like Figure 2 As shown, the slide clamping module 2 includes a slide mounting plate 21 and a slide pressing plate 22 slidably connected to the slide mounting plate 21. The slide mounting plate 21 has a slide mounting groove 211. The side of the slide mounting groove 211 facing the slide sample 3 is an open opening. Several elastic pressing plates 2111 with openings facing the slide sample 3 are fixedly connected inside the slide mounting groove 211. The height of the end of the elastic pressing plate 2111 facing the slide sample 3 is greater than the thickness of the slide sample 3, which facilitates the slide sample 3 to quickly align into the gap between the slide mounting groove 211 and the elastic pressing plate 2111, improving installation efficiency. When the elastic pressing plate 2111 fixes the slide sample 3, the elastic pressing plate 2111 applies a vertically downward force to the slide sample 3, thereby fixing the slide sample 3.
[0029] like Figures 2-5As shown, a plurality of elastic elements 23 are provided between the slide mounting plate 21 and the slide pressing plate 22. The elastic elements 23 have a tendency to push the slide pressing plate 22 against the slide sample 3. In at least one embodiment, the elastic element 23 is a spring. A sleeve plate 231 is installed on the inner wall of the groove 212 away from the slide mounting groove 211. The two ends of the elastic element 23 are respectively installed on the sleeve plate 231 and the slide pressing plate 22. The slide mounting plate 21 has a groove 212 that communicates with the side wall of the slide mounting groove 211. The slide pressing plate 22 is placed in the groove 212. A guide rail 2121 is installed in the groove 212 near the slide mounting groove 211. A slider 2122 is slidably connected to the guide rail 2121. The slide mounting plate 21 is mounted on the guide rail 2121 through the slider 2122. The guide rail 2121 provides a precise guiding effect for the reciprocating movement of the slide pressing plate 22. When the elastic element 23 pushes the slide pressing plate 22... When the slide plate 2122 slides smoothly along the guide rail 2121, it avoids the slide plate 22 from shifting or getting stuck during the movement. A sliding groove 213 is provided at the bottom of the groove 212 away from the slide mounting groove 211. A connector 221 is fixedly connected to one end of the slide mounting plate 21 near the sliding groove 213. A fixing member 1 is provided on the substrate. The fixing member 1 is located on the path of the slide mounting plate 21 to receive the slide sample 3. The distance between the connector 221 and the fixing member 1 is less than the forward distance of the slide mounting plate 21. In at least one embodiment, the fixing member 1 is mounted on the substrate by a bracket, so that the height of the fixing member 1 is higher than the bottom of the connector 221. After the slide mounting plate 21 passes the fixing member 1, the fixing member 1 pushes the slide plate 22 to overcome the elastic force of the elastic member 23 and move along the guide rail 2121 away from the slide sample 3.
[0030] like Figures 1-5As shown, the end of the connector 221 away from the slide mounting plate 21 extends through the groove 213. The projection of the end of the connector 221 extending through the groove 213 on the side of the fixing member 1 in the horizontal direction at least partially coincides with the fixing member 1. When the slide mounting plate 21 moves towards the receiving slide sample 3, the fixing member 1 can abut against the connector 221. When the slide sample 3 is pushed into the slide mounting groove 211, the slide pressure plate 22 can be completely retracted into the groove 212, ensuring that the slide sample 3 smoothly enters the slide mounting groove 211. When the slide mounting plate 21 moves away from the receiving slide sample 3, the connector 221 is released from the restriction of the fixing member 1, and the elastic member 23 pushes the slide pressure plate 22 along the guide rail 2121 towards the slide sample 3, thereby pressing the slide pressure plate 22 against the slide sample 3. The slide 2111 fixes the slide sample 3 from two directions, strengthening the fixation of the slide sample 3 and reducing the risk of displacement of the slide sample 3 during subsequent detection or movement. This ensures that the slide sample 3 can maintain a stable state during subsequent detection or observation operations, thereby improving the stability and accuracy of the slide sample 3. The projection width of the end of the connector 221 that protrudes from the slide groove 213 on the bottom surface of the slide mounting plate 21 in the vertical direction is greater than the width of the slide groove 213, so that the connector 221 can move stably along the slide groove 213 without separating from the slide mounting plate 21. The groove 212 and the slide pressure plate 22 are L-shaped. When the connector 221 is not in contact with the fixing member 1, one end of the slide pressure plate 22 protrudes from the groove 212 and enters the slide mounting groove 211, and the slide pressure plate 22 will not detach from the groove 212.
