Description

Technical Field

[0001] The utility model relates to the technical field of dyeing equipment, in particular to an automatic waste liquid suction mechanism for a slide glass. Background Art

[0002] In biological research or medical fields, in order to better observe the morphology and structure of cells, biological sections are usually performed and placed on a slide for observation under a microscope.

[0003] In order to better transmit light for observation, biological sections are usually required to be thin. This makes the natural pigments and cells almost colorless and transparent, which is not conducive to observation. It is usually necessary to use a staining machine to stain the cell walls and organelles with suitable dyes to achieve different color depths in different parts, which is more conducive to observation.

[0004] After the dyeing process of the dyeing machine is completed, it is usually necessary to remove the waste liquid. The existing practice is to use a dividing plate to load the material, and move it one by one to the bottom of the slide for dyeing. The suction port of the waste liquid suction mechanism is fixed, and the size of the suction port is basically the same as the dyeing area. The indexing rotation moves to the bottom of the dyeing mechanism for dyeing. Since the slides are placed relatively compactly, it is more troublesome to adjust the rotation index of the dividing plate, and it cannot be guaranteed to move to the center under the waste liquid suction mechanism, which affects the liquid suction effect and causes waste liquid residue. It cannot meet the user's usage needs and is not conducive to improving the competitiveness of the product. Utility Model Content

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, the utility model is an automatic waste liquid suction mechanism for a glass slide, including a liquid suction frame, a multi-axis liquid suction drive module is provided on the liquid suction frame, the multi-axis liquid suction drive module includes at least two liquid suction drive components in different directions, and the multiple liquid suction drive components are connected in sequence through the moving end of the liquid suction drive component. A liquid suction component is fixedly provided on the moving end of the multi-axis liquid suction drive module, and the liquid suction component includes a liquid suction body 2, a liquid suction head 3, a liquid suction recovery pump module and a liquid suction recovery tube 4. A liquid suction channel is provided in the liquid suction body 2, and a pipette interface and a suction head interface are provided on the liquid suction body 2. One end of the liquid suction recovery tube 4 is connected to the pipette interface, and the other end of the liquid suction recovery tube 4 is connected to the liquid suction recovery pump module, and the liquid suction head 3 is connected to the suction head interface.

[0023] Through the setting of the multi-axis staining drive module, it can effectively replace the traditional solution of selecting a dividing plate for rotating feeding and a fixed suction port position. By adopting this solution, the pipette head 3 can be effectively driven to move in multi-axis directions, thereby improving the flexibility of the position of the pipette head 3 and realizing the precise movement of the pipette head 3 to the top of the slide to absorb waste liquid.

[0024] The liquid pipetting head 3 includes a nozzle portion 31 and a connecting portion 32. The nozzle portion 31 is flat, and its cross section is a rectangular. A nozzle channel is provided in the nozzle portion 31. The width of the nozzle portion 31 is greater than or equal to the width of the slide.

In addition, the width of the nozzle is greater than or equal to the width of the slide, and can effectively cooperate with the multi-axis liquid suction drive module to fully cover the entire area from head to tail at one time, thereby increasing the coverage area of ​​the liquid suction and improving the efficiency of waste liquid suction.

[0027] By making the width of the connecting portion 32 smaller than the connecting portion 32 , the speed at which the liquid is recovered can be further increased, and the waste liquid recovery can be smoother by providing the guiding inclined surface 311 .

[0028] The multi-axis liquid suction drive module includes two liquid suction drive components, which are the liquid suction X-axis drive component and the liquid suction Y-axis drive component.

[0031] The X-axis pulley 54 is driven by the X-axis drive motor 53 to move the liquid suction, thereby driving the Y-axis drive assembly to slide on the X-axis drive guide rail 52.

[0032] There are two liquid suction X-axis driving rails 52 and two liquid suction X-axis driving sliders 62 . The two liquid suction X-axis driving sliders 62 match the two liquid suction X-axis driving rails 52 one by one.

[0033] By providing two liquid suction X-axis driving guide rails 52, the stability of the movement of the liquid suction Y-axis driving assembly can be effectively improved.

[0034] The liquid suction X-axis drive assembly also includes a liquid suction X-axis in-place sensor, and the liquid suction Y-axis drive assembly is provided with a liquid suction X-axis in-place sensing plate that cooperates with the liquid suction X-axis in-place sensor.

[0035] By setting the liquid suction X-axis in-place sensor, it is possible to effectively determine whether the liquid suction Y-axis drive component has moved to the position.

[0036] The liquid suction Y-axis drive assembly includes a liquid suction Y-axis drive mounting plate 63, on which a liquid suction Y-axis drive guide rail 64, a liquid suction Y-axis drive motor 65 and a liquid suction Y-axis pulley 66 are provided. The liquid suction body 2 is provided with a liquid suction Y-axis belt clamping member 21 and a liquid suction Y-axis drive slider 22. The liquid suction Y-axis drive slider 22 is slidingly connected to the liquid suction Y-axis drive guide rail 64, and the liquid suction Y-axis belt clamping member 21 is connected to the liquid suction Y-axis pulley 66.

[0037] The Y-axis pulley 66 is driven by the Y-axis drive motor 65 to move the liquid suction mounting frame, thereby driving the liquid suction mounting frame to slide on the Y-axis drive guide rail 64.
