[0002] A staining analyzer is an instrument used to observe and analyze cell or tissue specimens; the slide is usually made of a flat transparent glass or plastic, rectangular or square in shape. When the object to be tested (such as cells, tissues or liquid samples) needs to be observed and analyzed, the object to be tested can be marked by different staining methods, and then the specimen can be imaged and analyzed using optical technology, fluorescence technology and other methods.

[0003] During the staining process, the stain usually needs to be dripped onto the specimen from a higher position so that it can fall freely, reduce air resistance, and distribute the stain more quickly and evenly when it falls on the slide. Due to the large displacement difference, it is difficult for medical staff to drop the stain in the center of the slide, and it is easy to drop it on the edge of the slide or the laboratory table, resulting in sample waste.

[0029] Furthermore, a single chip microcomputer (not shown in the figure) for controlling the movement of the mobile vehicle 8 is arranged inside. In this embodiment, the single chip microcomputer is selected as but not limited to an ARM Cortex-M core single chip microcomputer.

[0030] A plurality of slide grooves 12 are provided on the upper surface of the test bench 5 and are evenly distributed along the direction of the slideway 6 and fit with the glass slide 2. A mounting plate 13 is slidably arranged in the slide groove 12. A control component 14 for controlling the movement of the mounting plate 13 is arranged below the mounting plate 13; and the center point of the mounting plate 13 is arranged above the movement trajectory of the dropper 3.

[0031] A through-beam sensor is provided on the upper surface of the test bench 5 and the lower surface of the horizontal plate 10, and the symmetrical sensor is connected to the single-chip computer signal.

[0032] Embodiment 2 is described based on Embodiment 1 with reference to the accompanying drawings:

[0033] The control assembly 14 includes an extension rod 17 arranged on the lower surface of the mounting plate 13, a lifting plate 18 slidably connected to the slide groove 12 is arranged on the lower surface of the extension rod 17, limiting grooves 19 are provided on both sides of the slide groove 12, and limiting blocks 20 fixedly connected to the lifting plate 18 are slidably arranged in the limiting grooves 19, a tension spring 21 is fixedly arranged between the bottom of the slide groove 12 and the lower surface of the lifting plate 18, a threaded column 22 is threadedly connected to the bottom of the slide groove 12, a limiting plate 23 is fixedly arranged on the upper surface of the threaded column 22, and the diameter of the limiting plate 23 is larger than the diameter of the threaded column 22, and the upper surface of the limiting plate 23 is set as an arc surface, and the bottom end of the threaded column 22 passes through the test bench 5 and is located below the test bench 5 and is fixedly provided with a knob 24.

[0034] Under normal conditions, under the restoring action of the tension spring 21 , the lifting plate 18 is driven to move downward until the lower surface of the limiting block 20 abuts against the inner bottom wall of the limiting groove 19 , and the mounting plate 13 is located in the sliding groove 12 .

[0035] Working principle: When dripping dye onto a slide, first squeeze the dripping capsule 301 of the dropper 3 to suck the dye dripping liquid into the dropper 3, then place the glass slide 2 on the mounting plate 13, and control the movement of the mobile vehicle 8 through the single-chip microcomputer. When the cross-beam generator 15 and the cross-beam receiver 16 are in cross-beam, the signal is transmitted to the single-chip microcomputer, and the single-chip microcomputer controls the mobile vehicle 8 to stop. At this time, the dropper 3 corresponds to the center point of the glass slide 2, and the dripping capsule 301 is squeezed to allow the dye dripping liquid to be accurately dripped to the center of the glass slide 2.

[0036] After the drop is completed, the knob 24 is turned, and the threaded column 22 rotates and moves upward, pushing up the lifting plate 18, and the mounting plate 13 connected to the lifting plate 18 through the extension rod 17 moves upward, so that the mounting plate 13 slides out of the slide groove 12, making it convenient to take out the slide 2.

[0037] After the glass slide 2 is taken out, the knob 24 is turned, and the threaded column 22 rotates and moves downward. Under the restoring elastic force of the tension spring 21, the lifting plate 18 is driven to return downward to the initial state, thereby driving the mounting plate 13 to slide into the slide groove 12 again.
