In practical applications, the parallelism between the sample plane and the scanning motion reference plane must be controlled within a few micrometers; otherwise, it will directly affect the scanning quality and imaging accuracy, making it difficult to meet the needs of high-resolution diagnosis and scientific research.

[0037] With the rapid development of high-end medical optical equipment such as OCT (Optical Coherence Tomography), laser confocal microscopy, and digital pathology slide scanning, the requirements for spatial resolution, depth-of-field consistency, and image stitching accuracy of scanning systems have increased to the sub-micron level. In practical applications, the parallelism between the sample plane and the scanning motion reference plane must be controlled within a few micrometers; otherwise, it will directly affect the scanning quality and imaging accuracy, making it difficult to meet the needs of high-resolution diagnosis and scientific research.

[0038] Existing equipment generally adopts an "elevated" stage structure. In order to improve the leveling efficiency of precision medical optical scanning equipment, the inventors came up with the idea of ​​installing fisheye bearings on the support columns and connecting the main board platform through the fisheye bearings to achieve rapid leveling.

[0039] After leveling the motherboard platform, the next step is to install the sample on the motherboard platform's mounting station. Because the motherboard platform is relatively thin, inaccurate alignment during sample installation may cause the motherboard platform to warp, which in turn affects the scanning quality and imaging accuracy.

[0040] To solve the above problems, this utility model proposes a precision stage 1000. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 A schematic diagram of the structure of an embodiment of the precision stage 1000 provided by this utility model.

[0041] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 This utility model proposes a precision stage 1000, including a motion platform 1, a connecting assembly, a main board platform 3, and two guide blocks 4. The connecting assembly includes multiple support columns 21 and multiple fisheye bearings 22. Each support column 21 is vertically connected to the motion platform 1. The end of each support column 21 away from the motion platform 1 is connected to the main board platform 3 via a fisheye bearing 22. The main board platform 3 has an installation port 3a. The two guide blocks 4 are respectively located on the periphery of the opposite side walls of the installation port 3a. Each guide block 4 and one side wall of the installation port 3a form a guide groove 4a. The two guide grooves 4a are configured for inserting a sample a.

[0042] The motion platform 1, serving as the basic support structure, can be made of aluminum alloy or steel to balance lightweight and rigidity. The fisheye bearing 22 is preferably made of stainless steel to reduce frictional loss. The mounting port 3a of the main board platform 3 must match the dimensions of the standard sample a, and the sidewalls of the mounting port 3a can be chamfered to avoid scratching the sample a. The guide groove 4a of the guide block 4 is slightly wider than the thickness of the sample a, and a polytetrafluoroethylene (PTFE) gasket can be added inside the groove to reduce insertion resistance.

[0043] In the technical solution of this utility model, the fisheye bearing 22 enables multi-degree-of-freedom fine adjustment of the main board platform 3, which can quickly compensate for the parallelism deviation between the motion platform 1 and the scanning reference plane; the independent lifting function of the support column 21 can accurately correct local height differences, avoiding stress concentration caused by the traditional overall leveling method; the guide groove 4a structure ensures the positioning accuracy of sample a while effectively suppressing platform warping during the installation process through double-sided constraints; thereby achieving the purpose of improving leveling efficiency and ensuring the installation accuracy of sample a.

[0044] Please refer to Figure 2 and Figure 3 In one embodiment of this utility model, an inclined surface 3a1 is formed on each of the opposite side walls of the mounting port 3a; the angle between each inclined surface 3a1 and the plane where the corresponding guide block 4 is located is defined as α, where α < 90°.

[0045] The inclined surface 3a1 allows the sample a to achieve better guidance when inserted into the guide groove 4a. As a preferred embodiment, the inclined surface 3a1 can be formed by machining or casting, with its surface roughness controlled below Ra0.8 to ensure smoothness. Furthermore, the inclination angle α of the inclined surface 3a1 is preferably between 45° and 80° to balance guidance effect and structural strength.

[0046] By setting the inclined surface 3a1, the problem of warping of the mainboard platform 3 caused by inaccurate alignment during sample a insertion is effectively solved. Due to the synergistic effect of the inclined surface 3a1 and the guide groove 4a, sample a can slide into the predetermined position more smoothly, reducing the generation of lateral forces. As a result, the mainboard platform 3 is subjected to more uniform force during sample a installation, avoiding deformation caused by local stress concentration. Compared with the prior art, this solution significantly improves the accuracy and ease of operation of sample a installation while ensuring structural simplicity and reliability.

[0047] Please refer to Figure 2 and Figure 3 In one embodiment of the present invention, the guide block 4 includes an inlet portion 41, which is located at the rear end of the guide block 4 along the insertion direction of the sample a; the thickness of the inlet portion 41 gradually increases along the insertion direction of the sample a to form a guide slope 41a for guiding the insertion of the sample a.

[0048] The inlet section 41 is a gradient structure located at the end of the guide block 4, and its thickness change can be achieved through linear gradient. Specifically, the angle between the guide slope 41a and the horizontal plane can be set to 30°-60°, with 45° being a preferred choice. The inlet section 41 can be made of metal integrally formed with the guide block 4, or it can be achieved by adding a polymer liner. The sloped guide structure solves the problem of difficult alignment when inserting sample a. When sample a contacts the inlet section 41, the guide slope 41a converts the lateral offset into longitudinal displacement, forcing sample a to enter the guide groove 4a along a preset path. This avoids platform warping caused by forced insertion and reduces the requirements for operational precision. Compared with the existing planar guide structure, this design significantly improves the success rate of sample a installation on the first attempt without increasing the structural complexity of the platform.

[0049] Please refer to Figure 5 and... Figure 6 In one embodiment of the present invention, the fisheye bearing 22 includes an outer ring 221 and an inner ring 222, with the inner ring 222 slidingly abutting against the outer ring 221; the outer ring 221 is detachably connected to the main board platform 3; and the inner ring 222 is detachably connected to the end of the support column 21 away from the motion platform 1.

[0050] Specifically, the outer ring 221 is detachably fixed to the main board platform 3 via a threaded connection. The outer surface of the outer ring 221 has a positioning flange that matches the mounting holes of the main board platform 3, ensuring radial positioning accuracy during assembly. The inner ring 222 uses a spherical sliding structure to mate with the outer ring 221. Its inner hole is machined with internal threads, directly engaging with the external threads at the end of the support column 21. As a preferred embodiment, the outer ring 221 is made of stainless steel and precision ground, while the inner ring 222 is made of self-lubricating copper alloy. The clearance between their mating surfaces is controlled within the range of 0.01-0.03mm. The split-type spherical bearing 22 structure enables multi-degree-of-freedom leveling between the support column 21 and the main board platform 3. The rigid connection between the outer ring 221 and the platform ensures overall support rigidity, while the spherical sliding fit between the inner ring 222 and the outer ring 221 allows the support column 21 to adaptively deflect within a range of ±6°. Compared to traditional integral hinged structures, this design maintains the angle compensation capability during leveling while facilitating the replacement and maintenance of individual components through detachable connections.

[0051] Please refer to Figure 5 and Figure 6In one embodiment of this utility model, the fisheye bearing 22 further includes a locking screw 223 and a clamping screw 224. The main board platform 3 has a mounting hole and a clamping hole. The outer ring 221 abuts against the wall of the mounting hole, and the locking screw 223 passes through the mounting hole and is threadedly connected to the inner ring 222. The clamping screw 224 is threadedly connected to the wall of the clamping hole, and the nut of the clamping screw 224 abuts against the side of the outer ring 221 away from the locking screw 223, so as to limit the outer ring 221 within the mounting hole. Specifically, the locking screw 223 is used to fix the inner ring 222 to the support column 21, wherein the thread specification of the locking screw 223 must match the thread hole of the inner ring 222. The clamping screw 224 adopts a standard thread structure, and its nut diameter must be larger than the diameter of the clamping hole to ensure that it can effectively limit the outer ring 221. The mounting hole wall can be designed as a tapered structure to increase the contact area with the outer ring 221, and the clamping hole can be set as a countersunk hole to prevent the screw from protruding.

[0052] Please refer to Figure 1 , Figure 5 , Figure 7 as well as Figure 8 In one embodiment of the present invention, the connecting component further includes a plurality of clamping blocks 23, each clamping block 23 being disposed on the motion platform 1; each clamping block 23 is movably connected to a support column 21 so as to fasten the support column 21 to the motion platform 1 after the support column 21 is raised or lowered.

[0053] After the support column 21 completes the leveling of the main board platform 3 via the fisheye bearing 22, the clamping block 23 firmly fixes the support column 21 to the motion platform 1, preventing displacement of the support column 21 during subsequent use. This solves the problem of insecure fixation of the support column 21 after leveling in the prior art, ensuring the stability of the main board platform 3 during sample a scanning process. Compared with the traditional bolt fixing method, this solution is simpler to operate and achieves a more reliable fixing effect.

[0054] Please refer to Figure 7 and Figure 8 In one embodiment of this utility model, each clamping block 23 includes a fixing part 231 and an adjusting part 232; both fixing parts 231 are provided on the motion platform 1; the fixing part 231 and the adjusting part 232 surround to form a clamping hole 23a, and there is a clamping gap 23b between the fixing part 231 and the adjusting part 232 communicating with the clamping hole 23a; one end of each support column 21 away from the fisheye bearing 22 passes through a clamping hole 23a and is connected to the motion platform 1; the adjusting part 232 is movably connected to the fixing part 231 to adjust the size of the clamping gap 23b.

[0055] Specifically, the connection between the fixing part 231 and the adjusting part 232 can be achieved in various ways. For example, the adjusting part 232 can be slidably connected to the fixing part 231 via a slide rail structure, or a hinged connection can be used to achieve relative rotation, or the fixing part 231 and the adjusting part 232 can be integrally formed. The adjustable clamping block 23 structure enables rapid fastening of the support column 21. When the height of the support column 21 needs to be adjusted, the clamping gap 23b can be loosened first, and the clamping block 23 can be tightened after the height is adjusted to the correct position. This design avoids the hassle of repeated disassembly required by traditional fixed connection methods, greatly improving the convenience of leveling operations. At the same time, the adjustable characteristic of the clamping gap 23b ensures that the support column 21 will not wobble during lifting and lowering, guaranteeing leveling accuracy. Compared with existing technologies, this solution significantly improves the leveling efficiency of the platform while ensuring connection strength.

[0056] Please refer to Figure 7 and Figure 8 In one embodiment of the present invention, the clamping block 23 further includes a clamping screw 233, which passes through the adjusting part 232 and the clamping gap 23b and is threadedly connected to the fixing part 231; the motion platform 1 also has a plurality of clamping threaded holes, and each support column 21 passes through the corresponding clamping hole 23a and is threadedly connected to a clamping threaded hole.

[0057] Specifically, the clamping screw 233 is used to securely connect the adjusting part 232 and the fixing part 231. Rotating the clamping screw 233 changes the width of the clamping gap 23b. The clamping threaded hole is located on the motion platform 1 and engages with the threaded structure at the end of the support column 21 to achieve axial fixation. The threaded connection enables rapid positioning, reliable fixing, and quick height adjustment of the support column 21. Tightening the support column 21 adjusts its height. After height adjustment, rotating the clamping screw 233 moves the adjusting part 232 closer to the fixing part 231, thereby reducing the clamping gap 23b and clamping the support column 21. Simultaneously, the threaded engagement between the end of the support column 21 and the clamping threaded hole prevents vertical displacement of the support column 21. This dual fixing mechanism effectively solves the problem of easy loosening of the support column 21 after leveling the traditional stage, ensuring the stability of the mainboard platform 3 during sample a installation and use. Compared to clamping methods relying solely on friction, the threaded connection offers higher positioning accuracy and vibration resistance.

[0058] Please refer to Figure 1 and Figure 5 In one embodiment of the present invention, the peripheral wall of the support column 21 is provided with two wrench grooves 21a that are disposed opposite to the support column 21 for inserting a wrench.

[0059] Specifically, the wrench grooves 21a are symmetrically formed grooves on the outer wall of the support column 21, and their dimensions match those of a standard wrench. By providing symmetrically distributed wrench grooves 21a on the support column 21, the support column 21 can be directly rotated and adjusted using a standard wrench. When adjusting the height of the support column 21, the wrench can simultaneously engage both sides of the wrench grooves 21a to apply torque, avoiding the problem of the support column 21 deflecting due to unilateral force. This structural design makes leveling operations more convenient and stable.

The specific structure of the precision stage 1000 is as described in the above embodiments.
