Description

Technical Field

[0001] The utility model relates to the fields of intelligent agricultural machinery and equipment and biological science technology, and in particular to a device for automatically adsorbing and pushing and collecting a glass slide on a loading platform. Background Art

[0002] An efficient stage is of great significance for remote monitoring of airborne fungal spores in the field. It does not require human intervention during its operation, has high efficiency and saves manpower, and lays a technical foundation for the full-automatic monitoring of airborne fungal spores. The device and method for automatic vacuum adsorption and glass slide supply and collection provided by the utility model is a fully automatic intelligent stage device for monitoring fungal spores, which is used for remote unmanned intelligent collection of fungal spore microscopic images.

[0003] At present, the main method for observing and collecting microscopic images of fungal spores in the laboratory is to manually place a slide on the stage and fix the slide with a specimen clamp. Then, the position of the stage is adjusted by manually rotating the XY axis knob to observe and obtain spore images at different positions. This method of manually replacing and fixing slides not only lacks automation, but also fails to achieve automatic, real-time and large-scale monitoring of spore concentrations in farmland air, making it difficult to grasp the real-time situation of the dynamic changes of fungal spores in farmland. In order to improve the above shortcomings, Professor He Dongjian and Professor Lei Yu proposed an XY axis horizontal intelligent moving stage device in the authorized utility model patent "A fungal spore microscopic image acquisition device and method with controllable collection points" (application number: CN201811253450.6). However, the device uses a stepper motor to drive a limit pin to fix the slide, which increases the complexity of the stage. In addition, the stage does not yet have the function of automatically pushing the slide to the table, which limits its degree of automation to a certain extent. Utility Model Content

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a device for automatically adsorbing and pushing and retracting a glass slide on a stage. By arranging two rows of five small holes in the glass slide groove of the stage and connecting them to a vacuum pump, vacuum negative pressure adsorption and fixing of the glass slide can be achieved. At the same time, the device has the functions of providing and recovering glass slides, which provides technical support for the automation and intelligence of fungal spore image acquisition devices.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts a device for automatically adsorbing and pushing and collecting a slide glass on a stage, comprising a stage, the stage having a first slide table moving in a straight direction, a first driving assembly providing power for the first slide table and driving the first slide table to move, a base being arranged on the first slide table and a table top being arranged on the top surface of the base, the length direction of the base being parallel to the sliding direction of the first slide table, a second driving assembly being also installed on the base table in the width direction, the second driving assembly having a moving seat driving the table top to move in the width direction, the number of the limiting glass strips being two and both of the limiting glass strips being located on the table top and having a limiting space for limiting the movement of the slide glass, an adsorption structure being installed in the limiting space to adsorb the slide glass in the limiting space, the above-mentioned adsorption structure comprising two groups of air hole groups arranged in parallel, the air hole groups being connected to the air extraction holes through apertures, the air extraction holes being connected to the vacuum pump through a hose, the air hole group having five air holes, a glass pusher for moving the slide glass is provided in the limiting space, and the pushing direction of the glass pusher is parallel to the direction in which the second driving assembly pushes the base.

[0006] The above structure realizes vacuum negative pressure adsorption and fixation of the slide through the adsorption structure, and at the same time realizes the modification of the X-axis and Y-axis structures of the stage through the first drive component and the second drive component. Under the action of the glass pusher, the movement of the stage is coordinated to realize the recovery of the slide and the adjustment of the position of the slide before collecting the spore image, which provides technical support for the automation and intelligence of the fungal spore image collection device.

[0007] As a further optimization of the above solution, one of the glass limiting strips extends upward from the top surface close to the glass slide side to form a glass supply block. Combined with the unique structure of the existing slide chamber, during the movement of the first slide, the glass supply block can export the glass slide in the slide chamber to realize the automatic export function. At the same time, the glass supply block has a certain height, which can better limit the glass slide within the limited space.

[0008] As a further optimization of the above solution, the first driving assembly has a first threaded rod extending along the length direction of the stage, the first threaded rod is connected to the first stepper motor and performs a rotational motion under the action of the first stepper motor, and the first slide is installed on the first threaded rod and performs a linear motion along the first threaded rod under the rotational motion of the first threaded rod;

[0009] The second driving assembly has a second threaded rod extending in the width direction of the stage, the second threaded rod is connected to the second stepping motor and performs a rotational motion under the action of the second stepping motor, the moving seat is mounted on the second threaded rod and performs a linear motion along the second threaded rod under the rotational motion of the second threaded rod, and the moving seat is connected to the above-mentioned table top;

[0010] The glass pusher has a third threaded rod extending along the width direction of the stage, the third threaded rod is connected to the third stepping motor and rotates under the action of the third stepping motor, the second slide is installed on the third threaded rod and moves linearly along the third threaded rod under the rotation of the third threaded rod, and the second slide is in contact with the slide.

[0011] By adopting the first drive assembly, the second drive assembly and the glass pusher with a threaded structure, the stage and the slide can be moved automatically, reducing manual intervention and significantly improving work efficiency. At the same time, the threaded structure makes the movement more stable and reliable, ensuring the precise positioning of the slide.

[0012] As a further optimization of the above scheme, a drag chain is configured in the width direction of the above base and is arranged parallel to the first slide. The drag chain has a fixed end and a movable end with fixed positions along the length direction. The fixed end and the movable end are connected in sequence through a first straight line segment, a bent segment and a second straight line segment. The above first straight line segment and the second straight line segment are arranged parallel in the vertical direction and the second straight line segment is located above the first straight line segment. The bent segment connects the above first straight line segment and the second straight line segment. An L-shaped aluminum bar is configured to connect the movable end to the base so that when the movable end moves with the base, the length of the second straight line segment is correspondingly transferred to the first straight line segment.

[0013] In order to ensure that the base is stable and undisturbed during movement, the drag chain is configured along the width direction of the base, parallel to the first slide, so that the drag chain can adapt to the movement of the loading platform, avoiding interference between the drag chain and the base, thereby improving the stability of the base movement.

[0014] As a possible example of the above-mentioned drag chain structure, a guide surface is formed on the upper surface of the first straight line segment, and the base extends toward one side of the drag chain to form a guide block that moves along the guide surface. Part of the second stepper motor is installed in the guide surface and makes the second stepper motor contact with the guide surface.

[0015] By designing structures such as guide surfaces and guide blocks, the stability of the base during linear movement is further enhanced. At the same time, the position of the second stepper motor during movement is limited, avoiding the possibility of motor position deviation, thereby ensuring precise movement of the table in the X-axis and Y-axis directions.

[0016] The utility model provides a device for automatically adsorbing and pushing and collecting a glass slide on a stage, which has the following beneficial effects:

[0017] The utility model adopts a method of fixing the glass slide by adsorbing the negative pressure of a vacuum pump, which simplifies the design of the stage, so that the position of the glass slide can be stabilized during the process of grease coating, scraping, and collecting spores, avoiding deviation, and ensuring the accuracy of subsequent spore microscopy operations. In addition, the glass pusher is integrated on the stage and can work in coordination with the movement of the stage to achieve the recovery of the glass slide and position adjustment before collecting spore images. The utility model not only makes the stage structure simpler, but also improves work efficiency, provides a solid technical foundation for the fully automatic capture and monitoring of spores, and has broad application prospects.

[0031] Please refer to the instruction manual Figure 1-8 The utility model provides a first embodiment of a device for automatically adsorbing and pushing and collecting a slide on a stage. In this embodiment, the device is composed of a first slide 21 that moves in a linear direction. A first driving component 2 provides power and drives the first slide 21 to move. In this embodiment, the first driving component 2 has a first threaded rod 22 that extends along the length direction of the stage 1. The first threaded rod 22 is connected to a first stepper motor 23 and rotates under the action of the first stepper motor 23. The first guide rail linear slide module is installed on the first threaded rod 22 and moves linearly along the first threaded rod 22 under the rotation of the first threaded rod 22.

[0032] A base 3 is provided on the first slide 21, and a table 4 is provided on the top surface of the base 3. The length direction of the base 3 is parallel to the sliding direction of the first slide 21. A second driving assembly 5 is installed on the base 3 to drive the table 4 to move in the width direction. The second driving assembly 5 has a second threaded rod 52 extending along the width direction of the stage 1. The second threaded rod 52 is connected to the second stepping motor 53 and rotates under the action of the second stepping motor 53. The second guide rail linear slide module is installed on the second threaded rod 52 and moves linearly along the second threaded rod 52 under the rotation of the second threaded rod 52. The moving seat 51 is connected to the above-mentioned table 4;

[0033] Two glass-limiting strips 6 are located on the table 4 to form a limiting space to limit the movement of the glass slide. The adsorption structure is installed in the limiting space to adsorb the glass slide. In the present embodiment, the adsorption structure includes two groups of air hole groups 9 arranged in parallel. The air hole group 9 is connected to the air suction hole 91 through the aperture. The air suction hole 91 is connected to the vacuum pump through a hose. The air hole group 9 has five air holes. When working, the vacuum pump is started, and the air hole group 9 generates negative pressure to adsorb the glass slide.

[0034] Furthermore, the top surface of one of the glass limiting strips 6 close to the side of the glass slide extends upward to form a glass supply block 61. Combined with the unique structure of the existing slide bin, during the movement of the first slide 21, the glass supply block 61 can export the glass slide in the slide bin to realize the automatic export function. At the same time, the glass supply block 61 has a certain height, which can better limit the glass slide within the limited space.

[0035] It should be noted that in further examples, such as Figure 2 As shown, we also provide a glass slide bin, the lower surface of which forms a sliding channel for the glass slide to enter and for pushing the glass slide inside the glass slide bin out.

[0036] The glass pusher 7 is located in the limited space and is used to push the glass slide. The pushing direction of the glass pusher 7 is parallel to the pushing direction of the second driving assembly 5. Specifically, the glass pusher 7 has a third threaded rod 71 extending along the width direction of the stage 1. The third threaded rod 71 is connected to the third stepper motor 72 and rotates under the action of the third stepper motor 72. The second slide 73 is installed on the third threaded rod 71 and makes a linear motion along the third threaded rod 71 under the rotation of the third threaded rod 71. The second slide 73 is in contact with the glass slide.

[0037] Furthermore, a drag chain 8 is configured in the width direction of the above-mentioned base 3 and the drag chain 8 is arranged parallel to the first slide 21. The drag chain 8 has a fixed end 81 and a movable end 82 with fixed positions along the length direction. The fixed end 81 and the movable end 82 are connected in sequence through a first straight segment 83, a bent segment 84 and a second straight segment 85. The above-mentioned first straight segment 83 and the second straight segment 85 are arranged parallel in the vertical direction and the second straight segment 85 is located above the first straight segment 83. The bent segment 84 connects the above-mentioned first straight segment 83 and the second straight segment 85. An L-shaped aluminum bar 86 is configured to connect the movable end 82 with the base 3 so that when the movable end 82 moves with the base 3, the length of the second straight segment 85 is correspondingly transferred to the first straight segment 83. In this structure, the drag chain 8 is configured along the width direction of the base 3 and is parallel to the first slide 21, so that the drag chain 8 can adapt to the movement of the loading platform 1, avoiding interference between the drag chain 8 and the base 3, thereby improving the stability of the movement of the base 3.

[0038] As a further possibility of the above embodiment, a guide surface 831 is formed on the upper surface of the first straight segment 83, and the base 3 extends toward the side of the drag chain 8 to form a guide block 31 that moves along the guide surface 831. Part of the second stepper motor 53 is installed in the guide surface 831 and makes the second stepper motor 53 contact the guide surface 831. By designing structures such as the guide surface 831 and the guide block 31, the stability of the base 3 during the linear movement process is further enhanced. At the same time, the position of the second stepper motor 53 during the movement process is limited, avoiding the possibility of the motor position being offset, thereby ensuring the precise movement of the table 4 in the X-axis and Y-axis directions.

[0039] The working steps of this embodiment are as follows:

[0040] Start the vacuum pump, and the pore group 9 generates negative pressure to adsorb the glass slide;

[0041] The first slide 21 is controlled to move linearly by the first driving assembly 2, and the second driving assembly 5 controls the width direction movement of the table top 4;

[0042] The guide block 31 moves along the guide surface 831 to ensure the movement accuracy, and the limit strip 6 limits the movement range of the slide to ensure the accurate positioning of the slide;

[0043] After use, the glass pusher 7 is driven by the third stepping motor 72 to push the glass slide and push the glass slide into the recovery box.

[0044] As a further possibility of the above embodiment, we further provide a microprocessor, a vaseline scraping mechanism, a microscopic image acquisition mechanism, a spore capturing air duct mechanism, a relay I / O control module, a microscope spot beam light source, an air suction fan, a vacuum pump and a solar power supply system, etc. The microprocessor is the control core, which is connected to each driver and the relay I / O module through the RS485 bus to realize signal transmission and control, and is connected to the digital lens of the microscopic image acquisition mechanism through the USB interface to realize image transmission and control. The number of the drivers is the same as that of the stepper motor, and the driver control adjusts the number of pulses through the PWM signal to drive not only the rotation and start and stop control of the motor, but also the above-mentioned vaseline scraping mechanism, microscopic image acquisition mechanism, and spore capturing air duct mechanism are also connected to stepper motors. Under the joint drive of the stepper motor, each execution structure can automatically complete fully automatic intelligent continuous operations such as pushing and removing slides, scraping vaseline, capturing spores in the air, microscopic image acquisition and slide recovery.

[0045] The relay I / O module is connected to the suction fan and the control module. The control module adopts a PT4115 chip with adjustable output current. The output current is adjusted by outputting PWM signals with different duty cycles, thereby achieving stable and quantitative adjustment of the suction fan speed and the luminous intensity of the microscope point beam light source.

[0046] The solar power supply system supplies power to the entire device, realizing fully automatic intelligent collection of spore microscopic images driven by multiple motors.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
