Description

Microscopic examination platform mechanism

Technical Field

The utility model belongs to the field of medical instruments, and particularly relates to a microscopic examination platform mechanism.

Background

Scanning Electron Microscopy (SEM), abbreviated as scanning microscope, is a relatively modern tool for cell biology research invented in 1965, which mainly uses secondary electron signal imaging to observe the surface morphology of a sample, i.e. uses a very narrow electron beam to scan the sample, and generates various effects through the interaction of the electron beam and the sample, wherein the secondary electron emission of the sample is mainly used. Secondary electrons can produce an enlarged topography of the sample surface, which is created in time sequence as the sample is scanned, i.e. a magnified image is obtained using a point-by-point imaging method. Moreover, the obtained image can be stored in an electronic way, and the use is very convenient.

In the whole detection process of the microscope, a plurality of driving motors are required to be used as drivers to complete each process, in particular, the microscopic examination platform comprises an objective table, a pressing sheet is arranged on the objective table, and the pressing sheet presses the glass slide on the objective table. The object stage is arranged on the bidirectional sliding table, and the sample on the glass slide is observed and scanned gradually in different areas through the sliding of the bidirectional sliding table on the XY platform. Specifically, the bidirectional sliding table comprises an object stage, an X-axis platform and a Y-axis platform are arranged on the lower side of the object stage, the X-axis platform can slide along the X-axis, the Y-axis platform is arranged on the X-axis platform and can slide along the Y-axis, and the object stage is arranged on the Y-axis platform, so that the position of the object stage 1 can be adjusted on the horizontal plane at will.

It follows that if automated movement of the entire microscopy platform is to be achieved, at least three drives (typically motors) are required to drive. The first motor is used for pushing the slide glass to go up and down so as to be matched with the tabletting to stably fix the slide glass on the objective table. And the second motor and the third motor are all screw rod motors. The second motor drives the X-axis platform to slide along the X-axis by rotating an X-axis screw rod in threaded connection with the X-axis platform. And the third motor is in threaded connection with the Y-axis platform through rotation and drives the Y-axis platform to slide along the Y axis.

But adopting three motors not only causes higher inherent cost, heavy weight and large occupied volume of equipment, but also causes the precision error to accumulate layer by layer due to the structure of accumulating the objective table and the bidirectional sliding table layer by layer, and is inconvenient for carrying out secondary heavy detection on samples in specific areas of samples on the glass slide.

The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art. In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

For example, in the claims, any of the claimed embodiments may be used in any combination.

As shown in fig. 1 and 2, the microscopic examination platform mechanism of the present utility model comprises an objective table 1, wherein the objective table 1 is mounted on a Y-axis sliding table 6, the objective table 1 slides along the Y-axis through the Y-axis sliding table 6, a slide block 2 sliding along the X-axis is provided on the objective table 1, and the slide block 2 is integrated with a front push plate 3, a press plate 5 and a rear push plate 4, so as to realize the X-axis movement and positioning of a slide. The front pushing plate 3, the pressing plate 5 and the rear pushing plate 4 on the pushing piece sliding block 2 can still be used for realizing clamping, loosening and front-back pushing, and only two drivers of an X-axis driver and a Y-axis driver are needed to complete all actions of the traditional microscopic examination platform mechanism.

Specifically, the stage 1 is provided with a positioning groove 11 for placing a slide glass, and the positioning groove 11 is also provided along the X axis. The pushing piece sliding block 2 is arranged on one side of the positioning groove 11 and moves along the positioning groove 11. The two ends of the slide block 2 are respectively provided with a front push plate 3 and a rear push plate 4, the front push plate 3 and the rear push plate 4 are respectively positioned at two sides of the glass slide, and the distance between the front push plate 3 and the rear push plate 4 is larger than the length of the glass slide. Thus, when the slide slider 2 slides forward along the X-axis, the front slide 3 pushes the slide forward along the positioning groove 11, so that the slide moves to the detection position, and the sample is detected by the corresponding microscope. Conversely, when the slide slider 2 slides in the opposite direction along the X-axis, the slide is pushed by the push plate to retreat along the positioning groove 11, so that the slide is moved back to the initial position to take out the slide from the positioning groove 11.

While the platen 5 is disposed between the front pusher plate 3 and the rear pusher plate 4, the distance between the front pusher plate 3 and the platen 5 is slightly less than or equal to the length of the slide, so that the platen 5 and the front pusher plate 3 can clamp the slide to position the slide. When the slide glass moves to a detection position under a corresponding microscope, the slide glass is clamped by the pressing plate 5 and the front pushing plate 3 so as to further detect a certain area of a sample on the slide glass; when the slide moves back to the initial position, the platen 5 and the front pusher plate 3 release the slide and the rear pusher plate 4 pushes the slide out of the initial position for easy slide replacement.

In order to realize the switch between the two states of pressing and releasing of the pressing plate 5, a clutch mechanism is arranged between the pressing plate 5 and the slide pushing block 2, and when the slide glass is pushed to a detection position by the front pushing plate 3, the pressing plate 5 and the slide pushing block 2 are fixed by the clutch mechanism, and the slide glass is clamped by the pressing plate 5 and the front pushing plate 3; when the slide is pushed back to the initial position by the rear pusher plate 4, the clutch structure separates the platen 5 from the pusher slide 2, and the platen 5 and the front pusher plate 3 release the slide.

Therefore, the pressing plate 5 has two different states through the pushing piece sliding block 2 and the clutch mechanism, and is matched with the front pushing plate 3 and the rear pushing plate 4, and the pushing piece sliding block 2 is driven by an X-axis driver to realize multiple functions of loading, clamping, unloading and the like of the glass slide. The pushing slide blocks 2 can be one or a plurality of pushing slide blocks, but are driven by one X-axis driver to perform uniform movement.

Example 1

In one embodiment, as shown in fig. 3, the clutch mechanism is a clamping structure, so that one end of the pressing plate 5 is clamped on the pushing piece sliding block 2. Specifically, the clutch mechanism comprises a clamping groove 51 arranged on the pressing plate 5 and a marble 21 arranged on the pushing piece sliding block 2, wherein the marble 21 is clamped with the clamping groove 51, so that the pressing plate 5 and the pushing piece sliding block 2 are fixed and separated. In addition, the locking groove 51 may be provided on the pusher slider 2, and the marble 21 may be provided on the pressing plate 5.

Wherein, the marble 21 can adopt a positioning ball, namely a part of a ball plunger, so that the clamping connection can be better realized. And the catching groove 51 is provided on the guide slope 52. As approaching the rear push plate 4, the distance between the guide slope 52 and the marble 21 gradually decreases, so that the guide slope 52 guides the marble 21 into the card slot 51.

In addition, in order to automatically realize the fixation and separation of the clamping connection, as shown in fig. 4, a stop block 12 is arranged at the junction of the detection position and the initial position of the pressing plate 5, and the stop block 12 can be abutted against the pressing plate 5 to limit the advance of the pressing plate 5 so as to separate the clutch mechanism. Specifically, the pressing plate 5 is slidably connected to the stage 1 through a limiting rail 13, and a stopper 12 is disposed at one end of the limiting rail 13, so as to limit the stroke of the pressing plate 5. The stop block 12 can be arranged on the object stage 1 in a protruding mode, and the limit rail 13 can be arranged in a concave mode, so that the stop block 12 is a side wall of the groove.

When the slide pushing slide block 2 moves to the junction between the detection position and the initial position and moves to the detection position, the clamping groove 51 is clamped with the marble 21, so that the pressing plate 5 and the front pushing plate 3 press the slide glass; moving to the initial position, the catch 51 separates from the marble 21, releasing the slide from the platen 5 and front pusher 3.

In order that the pressing plate 5 and the front push plate 3 can press the slide, one end of the front push plate 3 is provided on the slide slider 2, and presses the slide against the pressing plate 5 by elasticity. The elasticity can be realized by the elasticity of the front push plate 3 itself, but the elasticity is generally limited, so that an elastic member is preferably provided and the front push plate 3 is hinged to the push plate slider 2. One end of the elastic piece is connected to the front push plate 3, and the other end is connected to the push plate sliding block 2. The elastic member may be a torsion spring, a tension spring 31 (shown in fig. 1), etc. according to the situation, which is not described in detail in this embodiment. And the push plate sliding block 2 is provided with a slot 22, the slot 22 extends to one side of the rear push plate 4 and is used for inserting the front push plate 3, so that the front push plate 3 is limited, and the front push plate 3 is prevented from being excessively large in deflection angle due to hinging.

Example 2

Unlike embodiment 1, the clutch mechanism is a magnetic structure, the pusher slide 2 is provided with a support arm parallel to the front pusher plate 3, and the side of the support arm close to the rear pusher plate 4 adsorbs the pressing plate 5 through the magnetic structure, thereby achieving fixation and separation of the pressing plate 5 and the pusher slide 2 through magnetic force.

The magnetic structure can be two magnets with opposite magnetic poles, or one magnet and the other magnet are magnetic metals. Besides the basic clutch function, the magnetic structure can also play a role in ensuring compaction, but the structural stability is slightly inferior to that of the clamping mode of the embodiment 1.

The X-axis driver and the Y-axis driver are typically motors, and may be drivers such as cylinders. Specifically, the Y-axis sliding table 6 includes a base 61, and Y-axis sliding rails 62 are provided on both sides of the base 61, and the stage 1 is slidably connected to the base 61 through the Y-axis sliding rails 62. One side of the base 61 is provided with a Y-axis motor 63, and an output shaft of the Y-axis motor 63 is connected with a Y-axis screw 64, and the Y-axis screw 64 is in threaded connection with the object stage 1, so that the Y-axis screw 64 rotates to drive the object stage 1 to slide along the Y axis. And an X-axis motor 7 is fixed on one side of the object stage 1, an X-axis screw 71 is connected to an output shaft of the X-axis motor 7, and the X-axis screw 71 is in threaded connection with the pressing plate 5, so that the push piece sliding block 2 is driven to move along the X axis.

Of course, the Y-axis slide 6 of the present application is not essential, and the stage 1 alone may be provided to detect a sample.

The X axis and the Y axis refer to two directions perpendicular to each other, and because of the characteristics of the glass slide detection field, the X axis and the Y axis are generally two perpendicular directions of a horizontal plane for the convenience of understanding; but for some special detection environments the X-axis and Y-axis may be two perpendicular directions on either side.

It will be understood that the utility model has been described in terms of several embodiments, and that various changes and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof. Therefore, it is intended that the utility model not be limited to the particular embodiment disclosed, but that the utility model will include all embodiments falling within the scope of the appended claims.
