Description

Technical Field

[0001] The utility model belongs to the technical field of microorganism processing, and relates to a slide collecting device, in particular to a slide collecting device of an automatic smear device for microorganism samples. Background Art

[0002] Microbial sample smears are widely used in colony inoculation, culture, separation, and detection, and are an important task in microbial sample detection. Traditionally, manual smears are used. The operator takes the sample box and dips it into the sample to be tested. The smear pen dipped in the sample to be tested gently presses a small amount of the sample to be tested on the slide to complete the smear. The manual method has the problems of non-standard operation, large randomness of manual operation, high labor cost, and low efficiency.

[0003] To this end, a Chinese patent discloses an automatic smearing device for microbial samples [authorization announcement number CN206362604U], which can solve the problems of non-standard manual smearing operations. Driven by the first linear module, the second linear module and the third linear module, the suction cup sucks the smeared slide into the slide collection box, which is placed flat on the workbench, but it cannot effectively separate the slides and is easy to scratch the smear area.

[0004] For this purpose, a Chinese patent discloses a vacuum blood smear storage box [authorization announcement number is CN217199791U], which includes a box body and a storage box. The bottom of the storage box is provided with elastic clamping pieces, which are arranged in pairs. A gap is provided between a pair of clamping pieces, and a glass slide is fixed between two supporting pieces. The glass slide is placed between the two clamping pieces manually or by a manipulator. Manual placement is inefficient, and when placing by a manipulator, the glass slide is first sucked, and the glass slide is turned 90° before being inserted between the two clamping pieces. The manipulator has to complete the suction and turning actions, and the structure of the manipulator is complex and the cost is high. Utility Model Content

[0005] The utility model aims to solve the above problems in the prior art and proposes a slide collecting device which can automatically adjust the direction of the slide.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] The slide collecting device comprises a bottom plate and a slide collecting rack slidably arranged on the bottom plate, the slide collecting rack being provided with a plurality of slide placing cavities with openings facing upwards, the plurality of slide placing cavities being equidistantly distributed along the sliding direction of the slide collecting rack, a slide guide rack being fixed on the bottom plate and being located above the slide collecting rack, the slide guide rack being provided with a flipping guide structure for flipping the slide and conveying the slide downwards to the slide placing cavities.

[0008] The suction cup on the manipulator sucks the horizontal slide and places it on the slide guide frame. Under the action of the flip guide structure, the slide is flipped to a vertical state and then falls into the slide placement cavity below. After each slide is placed, the slide collection frame moves a distance so that the next slide placement cavity moves to the bottom of the flip guide structure. The flip guide structure can flip the slide, which has a good effect and simplifies the structure of the manipulator for grabbing the slide, thereby reducing costs.

[0009] In the above-mentioned slide collecting device, the flip guide structure includes a flip guide cavity that runs through the top and bottom and is arranged on the slide guide frame, one side of the flip guide cavity is a vertical surface, and the side opposite to the vertical surface is a guide surface, the distance from the guide surface to the vertical surface gradually decreases from top to bottom, the distance between the lower end of the guide surface and the vertical surface is not greater than the width of the slide placement cavity, and the upper end of the guide surface extends to the side away from the vertical surface to form a supporting surface, and the width of the supporting surface is less than half the width of the slide.

[0010] The suction cup on the robot arm absorbs the horizontal slide and transfers it to the flipping guide cavity. When the suction cup is released, the slide will tilt under the action of the supporting surface, and then slide downward under the action of the guide surface and the gravity of the slide. Finally, the slide is flipped into a vertical state under the joint action of the lower end of the guide surface and the vertical surface.

[0011] In the above-mentioned slide collecting device, the guide surface is a cylindrical surface, the straight line on the cylindrical surface is parallel to the vertical surface, and the center line of the cylindrical surface is not higher than the lower end of the vertical surface.

[0012] In the above-mentioned slide collecting device, the slide guide frame is provided with an inlet, the support surface and the flip guide cavity are located at the bottom of the inlet, one side of the inlet coincides with the vertical surface, and the other side of the inlet intersects with the support surface.

[0013] The insertion port is rectangular, with a width slightly larger than the width of the glass slide and a length slightly larger than the length of the glass slide. The suction cup on the robot absorbs the horizontal glass slide and transfers it into the insertion port, then releases the suction cup. The glass slide flips over under the action of the supporting surface, guide surface and vertical surface and falls into the glass slide placement cavity below.

[0014] In the above-mentioned slide collecting device, first protrusions are respectively provided at both ends of the vertical surface, and the distance between the two first protrusions is greater than the length of the smear area on the slide.

[0015] The purpose of providing the first protrusion is to prevent the smear area on the slide glass from contacting the vertical surface and to avoid the smear area from being scratched.

[0016] In the above-mentioned slide collection device, a slider driven by a linear module is slidably provided on the bottom plate, a collection rack placement box is provided on the slider, the slide collection rack is placed in the collection rack placement box, and the linear module is arranged on the lower side of the bottom plate.

[0017] Multiple slide collection racks can be placed in a row on each collection rack placement box. The relative position of the slide collection rack and the slide guide rack is changed by the action of the linear module, so that the slides dropped from the flip guide structure enter the slide placement cavity of the slide collection rack in sequence.

[0018] In the above slide collecting device, second protrusions are respectively provided at both ends of one side of the slide placement cavity, the distance between the two second protrusions is greater than the length of the smear area on the slide, and when the slide placement cavity moves to the bottom of the flip guide cavity, the second protrusion is located directly below the first protrusion. The second protrusion can prevent the smear area of ​​the slide from contacting the inner wall of the slide placement cavity.

[0019] In the above slide collecting device, the upper end of the second protrusion is a guiding slope. The depth of the slide placement cavity is approximately equal to the width of the slide, the length of the slide placement cavity is slightly greater than the length of the slide, and the width of the slide placement cavity is slightly greater than the thickness of the slide. The guiding slope can facilitate the slide to enter the slide placement cavity.

[0020] In the above-mentioned slide collecting device, the bottom of the slide placing cavity has a ventilation hole which passes through the slide collecting rack, and the ventilation hole is arranged opposite to the smear area of ​​the slide.

[0021] The span of the ventilation hole is smaller than the length of the glass slide, and the glass slide is arranged across the ventilation hole at the bottom of the glass slide placement cavity to prevent the generated aerosol from affecting the smear area of ​​the glass slide.

[0022] In the above slide collecting device, the upper parts of both ends of the slide collecting rack have clearance spaces, and the ends of the slides placed in the slide placement cavity are exposed in the clearance spaces. The ends of the slides are exposed in the clearance spaces, which makes it convenient to grab the slides in the slide placement cavity.

[0023] Compared with the prior art, the present slide collection device has the following advantages: the flipping guide structure can flip the slide, the overall structure is simple, the design is reasonable, the smear area of ​​the slide will not be scratched during the flipping process, the use effect is good, the structure of the robot for grabbing the slide is simplified, and the cost is reduced.

[0031] like Figure 1 and Figure 2 The slide collecting device shown comprises a horizontally arranged bottom plate 1, a linear module 4 is arranged below the bottom plate 1, a slider 5 driven by the linear module 4 is slidably arranged above the bottom plate 1, and the linear module 4 drives the slider 5 to slide on the bottom plate 1 along the length direction of the linear module 4 when the linear module 4 moves. A collecting rack placing box 6 is connected to the slider 5, and a plurality of slide collecting racks 2 arranged in rows are arranged in the collecting rack placing box 6, and the arrangement direction of the plurality of slide collecting racks 2 is the same as the sliding direction of the slider 5, and each slide collecting rack 2 is provided with a plurality of slide placing cavities 21 with openings facing upward, and the plurality of slide placing cavities 21 are equidistantly distributed along the sliding direction of the slide collecting rack 2.

[0032] like Figure 1 and Figure 2 As shown, a slide guide frame 3 located above the slide collection frame 2 is fixed on the bottom plate 1, and a flip guide structure for flipping the slide a and conveying the slide a downward to the slide placement cavity 21 is provided in the slide guide frame 3. The suction cup on the manipulator sucks the horizontal slide a and places it on the slide guide frame 3, and the slide a is flipped to a vertical state under the action of the flip guide structure, and then falls into the slide placement cavity 21 located below. After each slide a is placed, the slide collection frame 2 moves a distance, so that the next slide placement cavity 21 moves to the right below the flip guide structure.

[0033] like Figure 2 and Figure 3 As shown, the flip guide structure includes a flip guide cavity 31 which passes through the flip guide cavity 31 from top to bottom and is arranged on the glass slide guide frame 3.
