Description

TECHNICAL FIELD

[0001] The present application relates to the field of slide scanning, in particular to a slide dense arrangement type integral moving scanning device and scanning method. BACKGROUND

[0002] After sampling cervical cell samples, the samples need to be prepared into slides suitable for microscope observation through a certain preparation process. This usually includes coating cells on a slide and fixing and staining them in order to highlight cell structures and other important biological characteristics. After staining, a cover glass is covered to protect the sample and complete the preparation of the slide. Next, in order to carry out digital image analysis, the slides need to be placed in a special slide scanning device.

[0003] Modern image acquisition devices generally use a precise three-axis moving mechanism to carry an electronic scanning lens. With the increase of detection demand, traditional single-channel small scanners cannot meet the requirements, and large and medium-sized scanning devices have taken their place. Traditional centralized scanning devices usually place each small scanner in a centralized manner. Since each scanner is equipped with an independent preview component and a scanning component, if a mechanical arm is used for automatic feeding, the slide holder needs to be first inserted into the preview component, then extracted and inserted into the scanning component after previewing, and finally put back into the slide holder. The overall mechanical arm feeding and unloading process is long. Since each slide carries only one or two slides, the scanning work of a single small scanner is quickly completed, and the mechanical arm is still in the state of feeding and unloading for other small scanners. Therefore, it is difficult to match the mechanical arm and the scanner in terms of rhythm.

[0004] In addition, the cost of a single scanner of the above-mentioned centralized scanning device is high, and large-scale direct integration will undoubtedly make the overall cost of the equipment high. In fact, the detection efficiency is first of all the mechanical arm feeding and unloading, so the overall detection rhythm is not high, which does not match the cost. SUMMARY

[0005] The present application provides a slide dense arrangement type integral moving scanning device and scanning method, which solves the problem of mismatch between the scanner and the feeding and unloading mechanical arm when directly integrating a large number of small scanners.

[0046] The semicircular tray 4 and the horizontal support arm 102 are centrally hollowed out to avoid the bearing column 2.

[0047] The half-arc supporting plate 4 is semi-circular, and two half-arc supporting plates 4 on the positioning supporting plate 103 are spliced into a whole circle. With the rotation of the bearing column 2, the lifting sleeves 9 at different heights rotate synchronously.

[0048] The lower end of the bearing column 2 is provided with a rotating table 201, which can be a servo rotating table. The lower end of the tower 101 is provided with an outer support frame 202.

[0049] The positioning supporting plate 103 is divided into two halves along the diameter line, and the first positioning part 104 and the second positioning part 105 are distributed in different halves. Each outer arm 7 is distributed in the same half. When the first half is scanned, the half-arc supporting plate 4 of the second half can be removed and replaced.

[0050] In the preferred scheme, the glass placement groove of the half-arc supporting plate 4 is hollow in the center, the positioning supporting plate 103 is provided with a ring groove 106 for placing a lamp bead or a lamp strip, and a lead groove 107 is arranged at an angle for wire outlet.

[0051] The ring groove 106 is arranged at the sample position covered by the glass sheet to provide backlight, so that the details captured by the scanning mirror 5 are clearer.

[0052] In the preferred scheme, the glass placement groove is arranged in multiple layers along the radial direction of the bearing column 2, and the clamp 6 is arranged in multiple along the length direction of the outer arm 7. Each clamp 6 is provided with a scanning mirror 5.

[0053] The glass placement grooves can be densely arranged on the half-arc supporting plate 4, and multiple scanning mirrors 5 can be arranged along the diameter direction and the circumferential direction of rotation. Each scanning mirror 5 can work simultaneously and be responsible for scanning different sectors.

[0054] In the preferred scheme, the first positioning part 104 and the second positioning part 105 of the positioning supporting plate 103 are each provided with at least two positioning columns 108, and the half-arc supporting plate 4 is provided with at least two positioning holes 401. Each positioning hole 401 is sleeved with each positioning column 108.

[0055] In the preferred scheme, multiple positioning sleeves 8 are sleeved on the bearing column 2 along the height direction, the lifting sleeve 9 is sleeved outside the positioning sleeve 8, the outer wall of the positioning sleeve 8 is provided with a vertical sliding groove 801, the lifting sleeve 9 is provided with an anti-rotation pin 903, one end of the anti-rotation pin 903 is clamped in the sliding groove 801 and slides, the positioning sleeve 8 is sleeved with a sleeve frame 13, the lower end of the sleeve frame 13 is provided with a rotatable middle sleeve 16, and the lifting sleeve 9 is threadedly sleeved with the middle sleeve 16.

[0056] The outer wall of the middle sleeve 16 is sleeved with a synchronous belt ring 17, one end of the sleeve frame 13 extends out a connecting plate, and the second motor 14 is installed. The end of the second motor 14 is provided with a synchronous wheel, which is driven by the synchronous belt and the synchronous belt ring 17 to drive the middle sleeve 16 to rotate.

[0057] Because the lifting sleeve 9 is driven up and down by a threaded motion pair, the lifting adjustment accuracy is higher, which is more in line with the focus adjustment function of the scanning mirror 5.

[0058] In a preferred embodiment, a rotatable rotating flange 10 is fitted on the outer side of the lifting sleeve 9. The flange structure of the rotating flange 10 has a spiral tooth 1001 in the shape of a planar involute spiral on one side. The lifting sleeve 9 has a plurality of guide sleeves 901 along the circumference. The extended arm 7 is slidably sleeved with the guide sleeves 901. The side wall of the guide sleeve 901 has a slotted part 902. The outer wall of the extended arm 7 has a comb tooth structure 701. The spiral tooth 1001 passes through the slotted part 902 to be engaged in the comb tooth structure 701.

[0059] In the preferred embodiment, a gear ring 1002 is fitted on the outer side of the rotating flange 10, and a first motor 11 is connected to the lifting sleeve 9. A gear 12 is provided at the shaft end of the first motor 11, and the gear 12 meshes with the gear ring 1002.

[0060] The first motor 11 drives the gear ring 1002 through the gear 12 to rotate the rotating flange 10. The comb structure 701 slides relative to the tooth groove of the spiral tooth 1001. The side wall of the spiral tooth 1001 presses against the comb structure 701. Since the movement of the extension arm 7 is constrained by the guide sleeve 901 of the lifting sleeve 9, it ultimately pushes the extension arm 7 to extend and retract.

[0061] Multiple positioning rings 3 are fitted on the support column 2 along the height direction. The positioning rings 3 are provided with a groove 301. One end of the positioning sleeve 8 is fitted into the groove 301. A first positioning pin 302 and a second positioning pin 303 are also provided. The first positioning pin 302 passes through the positioning ring 3 to connect with the outer wall of the support column 2, and the second positioning pin 303 passes through the positioning ring 3 to connect with the lower end of the positioning sleeve 8.

[0062] The support column 2 has a pre-drilled positioning pin hole along its height. The first positioning pin 302 is threadedly connected to the positioning collar 3, with its front end inserted into the pin hole. First, install the lower positioning collar 3, and then install the upper positioning collar 3, positioning sleeve 8, lifting sleeve 9, rotating flange 10, and other parts.

[0063] The outer wall of the intermediate sleeve 16 near the sleeve frame 13 is provided with an annular groove, and the sleeve frame 13 is provided with a locking pin 1301, one end of which is inserted into the intermediate sleeve 16.

[0064] In a preferred embodiment, the first positioning part 104 and the second positioning part 105 are semi-arc-shaped grooves with one end open. A magnet block 109 is provided at the open end of the outer edge of the first positioning part 104 and the second positioning part 105, and the magnet block 109 is embedded in the lower end of the positioning plate 103.

[0065] The magnet block 109 at the opening end of the outer edge of the first positioning part 104 and the second positioning part 105 and the magnet block 109 embedded at the lower end of the positioning tray 103 are in corresponding positions and can be attracted to each other with opposite polarities.

[0066] Initially, the positioning tray 103 is not placed on the rest table 2201, and after the slide detection of the first positioning part 104 or the second positioning part 105 is completed, the clamp device 2101 pulls out the positioning tray 103 on the first positioning part 104 or the second positioning part 105 and places it on the rest table 2201 temporarily, and after all the layers are pulled out, the worker can manually remove the material preparation rack 22 and replace another empty material preparation rack 22, and stack the empty positioning tray 103 on the material preparation table 1901, then the multi-axis robot 21 switches to the suction cup device 2102 to fill the positioning tray 103 on the material preparation table 1901, and then switches to the clamp device 2101 to clamp and place the positioning tray 103 on the material preparation rack 22, and the preview lens 18 previews the positioning tray 103, and then the slide of the next positioning tray 103 is placed, and after all the positioning trays 103 are placed on the rest table 2201, the positioning trays 103 are clamped and placed on the first positioning part 104 or the second positioning part 105 of the scanning tower assembly 1.

[0067] Since the scanning mirrors 5 are moved in linkage in the rotation direction and the up-down movement direction, they cannot be adjusted individually. However, during actual processing and installation of the positioning tray 103, there is a certain degree of inclination, so if the photographing is performed according to the theoretical focal plane, there are many out-of-focus photos.

[0068] In the preferred scheme, the positioning tray 103 is sectorally divided with the central axis of the bearing column 2 as the center. Since the slides are distributed in an arc shape, the sector division boundary is preferably in the gap of the slide, so that each sector has only one slide;

[0069] The sector positions are numbered on the water surface area, and the number is associated with the slide ID;

[0070] Since the slide grooves on the positioning tray 103 are uniformly processed by a numerical control machine tool, the precision and consistency are high, and they can be regarded as being on the same plane, so at least three points that are far apart on the positioning tray 103 are selected as reference points;

[0071] The upper surface of each reference point on the positioning tray 103 is photographed by the same scanning mirror 5, the focus is clear by moving the lifting sleeve 9 up and down, and the height position of the lifting sleeve 9 is recorded;

[0072] The actual relative height of the upper surface of each reference point is calculated from the height position of the lifting sleeve 9 when the focus is clear at each reference point, and the inclination of the positioning tray 103 relative to the theoretical focal plane is calculated;

[0073] The actual focal plane lowest point and highest point coordinates of each slide on the positioning tray 103 are calculated according to the inclination of the positioning tray 103;

[0074] The clear depth height is determined according to the performance of the scanning mirror 5, and according to the clear depth height, the height between the lowest point and the highest point coordinates is isohypsic stratified, so that the shooting height area covers the actual focal plane;

[0075] Each layer clear depth area is divided into unit areas by sectors;

[0076] The background server performs intelligent analysis and records the number of defocus sectors at a specific height;

[0077] Layered shooting is performed in the height direction, and horizontal area shooting is performed in the rotation direction of the lifting sleeve 9 and the extension direction of the outer arm 7;

[0078] If the clear depth area does not cover the actual focal plane when the scanning mirror 5 moves in a certain sector at this height layer, no image is formed, if the clear depth area covers the actual focal plane, imaging is performed, reducing the proportion of useless pictures that are not clear, reducing the workload for later image stitching.

[0079] For planar areas, the scanning method is:

[0080] Since the scanning mirror 5 of the institute actually moves in an arc and radially, the smallest sector area of each sample area is determined, which is referred to as the actual sector area;

[0081] The actual sector area is divided into multiple small areas, and the entire sector area is shot area by area.

[0082] The above embodiments are only preferred technical solutions of the present application, and should not be regarded as limitations of the present application. The protection scope of the present application should be the technical solutions recited in the claims, including equivalent replacement solutions of the technical features recited in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present application.
