[0029] The present invention will be further described in detail below with reference to specific embodiments:

[0030] In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] like Figure 1 As shown, a microscope scanner capable of automatically wiping objective lenses includes an objective lens 1, a stage 2, and a wiping assembly. The objective lens 1 is mounted on an objective lens 1 turret and can be raised and lowered along the Z-axis. The stage 2 is located below the objective lens 1 and is driven to reciprocate along the X-axis and Y-axis by an X-axis drive assembly and a Y-axis drive assembly. The wiping assembly is mounted on the stage 2 and includes a replaceable wiping component for wiping the objective lens 1 and a fixing module for fixing the wiping component on the stage 2. The X-axis drive assembly and the Y-axis drive assembly drive the wiping component on the stage 2 to reciprocate in the X-axis and / or Y-axis directions to wipe the objective lens 1.

[0032] The wiping component is wiping paper 4. When wiping paper 4 becomes dirty, the operator replaces it with a new one. The fixing module consists of at least two clamping plates 3; Figure 3 As shown, each clamp 3 includes a fixing part 5 for fixing the clamp 3 to the stage 2 and a clamping part 6 that can elastically deform. The fixing part 5 has a mounting hole 7, and the clamp 3 is locked to the stage 2 by screws passing through the mounting hole 7. The clamping part 6 is a curved plate that extends downward and upward sequentially from the edge of the fixing plate. When the clamp 3 is in an unconstrained state, the lowest contact point of the clamping part 6 is lower than the bottom surface of the fixing plate. The lowest contact point of the clamping part 6 forms a vertical drop of 0.5-3mm with the bottom surface of the fixing plate. This 0.5-3mm vertical drop provides continuous downward pressure, keeping the wiping paper 4 in a taut state. This ensures that the wiping paper 4 is in close contact with the surface of the objective lens 1, avoiding incomplete cleaning due to insufficient pressure during wiping, and also ensuring that the wiping paper 4 does not shift during the wiping of the objective lens 1. The wiping paper 4 is rectangular, and there are two clamps 3. A pair of clamps 3 are respectively set on both sides of the length of the wiping paper 4. The clamps 3 can be adapted to wiping papers 4 of different thicknesses.

[0033] like Figure 1 , Figure 2As shown, a slide carrier plate that can reciprocate along the X-axis is mounted on the stage 2. A row of slides arranged along the X-axis is detachably mounted on the slide carrier plate. The position of the wiping device on the stage 2 along the Y-axis is aligned with the position of the slides on the stage 2 along the Y-axis. That is, as shown... Figure 1 As shown, a row of glass slides and wiping paper 4 are roughly aligned in the Y-axis direction, all located at... Figure 1 The dotted line is sufficient to ensure that the X-axis drive assembly and Y-axis drive assembly can move the stage 2 to the position directly below the objective lens 1 with a small displacement.

[0034] The X-axis drive assembly includes a first drive member that drives the stage 2 to reciprocate along the X-axis direction, and the first drive member is mounted on the receiving plate 8. The Y-axis drive assembly includes a second drive member that drives the receiving plate 8 to reciprocate along the Y-axis direction, and the second drive member is mounted on the frame 13. The X-axis drive assembly also includes a first linear guide module 11 that guides the movement of the stage 2 along the X-axis direction; the first linear guide module 11 includes a first linear guide rail and a first slider that slides with the first linear guide rail. The Y-axis drive assembly also includes a second linear guide module 12 that guides the movement of the receiving plate 8 along the Y-axis direction; the second linear guide module 12 includes a second linear guide rail and a second slider that slides with the second linear guide rail. The first driving component is a first linear motor 9, and the second driving component is a second linear motor 10. The stage 2 is fixedly mounted on the slide of the first linear motor 9, and the body of the first linear motor 9 is fixed on the receiving plate 8. The receiving plate 8 is fixedly mounted on the slide of the second linear motor 10, and the body of the second linear motor 10 is fixed on the frame 13. The first linear guide rail is fixed on the receiving plate 8, and the stage 2 is fixed on the first slider. The second linear guide rail is fixed on the frame 13, and the receiving plate 8 is fixed on the second slider. The first and second linear guide rail assemblies ensure the accuracy, stability, and reliability of the wiping paper 4's reciprocating movement along the X and Y axes. It should be noted that the X-axis drive assembly and the Y-axis drive assembly are also used to drive the slides on the stage 2 to reciprocate along the X and Y axes, so that the objective lens 1 can scan multiple slides. The wiping paper 4, fixed on the stage 2, uses the drive of the X-axis drive assembly and the Y-axis drive assembly to wipe the lens of the objective lens 1. This utilizes the existing structure of the microscope scanner and is highly practical.

[0035] The working principle of the microscope scanner with automatic objective lens 1 of this utility model is as follows: In the initial state, wiping paper 4 is clamped in the clamping plate 3. When the system detects that the preset cleaning cycle of objective lens 1 has been reached, the cleaning program is executed. The X-axis drive component and the Y-axis drive component drive the wiping paper 4 to move directly below objective lens 1. Objective lens 1 descends to contact wiping paper 4 through the Z-axis drive mechanism. The X-axis drive component and the Y-axis drive component drive the cleaning stage 2 to reciprocate in the X-axis and / or Y-axis directions, thereby driving the wiping paper 4 to reciprocate in the X-axis and / or Y-axis directions to wipe objective lens 1. After wiping objective lens 1, objective lens 1 returns to the working height, and the X-axis drive component and the Y-axis drive component drive the cleaning stage 2 back to the state of observing the slide. It should be noted that during the wiping process of objective lens 1 by wiping paper 4, when objective lens 1 of the microscope scanner senses abnormal resistance, it can automatically rise to prevent collision. This invention enables the automatic periodic cleaning of the objective lens 1, saving manpower. The periodic operation is more accurate and efficient through program control.
