[0041] Reference Figures 1 to 6 As shown, this embodiment provides a glass slide loading device, which includes a sample loading box 200 and a baffle 300 .

[0042] Specifically, the sample box 200 is provided with a receiving groove 201, in which a plurality of glass slides 400 can be stacked in a vertical direction; the baffle 300 is slidably arranged on the discharge side of the sample box 200 in a vertical direction, the baffle 300 can block the receiving groove 201, and a first magnetic member 301 is arranged on the baffle 300. The baffle 300 can assume a first state relative to the sample box 200 under its own gravity, and in the first state, the baffle 300 can prevent the glass slide 400 from sliding out of the receiving groove 201; the first magnetic member 301 can assume a second state relative to the sample box 200 under a repulsive force opposite to the self-gravity of the baffle 300, and in the second state, a discharge channel 202 for the glass slide 400 to slide out is formed between the baffle 300 and the sample box 200. The a direction in the figure can be a vertical direction.

[0043] In this embodiment, when the sample box 200 needs to be loaded, the baffle 300 can be slid open first, and then multiple glass slides 400 are stacked in the receiving slot 201 of the sample box 200, and the baffle 300 is reset. Due to the effect of gravity, the baffle 300 remains in the first state position, which can completely cover the receiving slot 201 to prevent the glass slide 400 from sliding out of the receiving slot 201 during the transportation of the sample box 200, effectively avoiding the loss and waste of the glass slide 400. In addition, the first magnetic member 301 is subjected to a repulsive force opposite to the self-gravity of the baffle 300, and the baffle 300 remains in the second state position, and a discharge channel 202 for the glass slide 400 to slide out is formed between the baffle 300 and the sample box 200, so as to facilitate the removal of the glass slide 400 and effectively ensure the efficiency of removing the glass slide 400.

[0044] In this embodiment, the height of the discharge channel 202 is slightly greater than the thickness of the glass slide 400. The height of the discharge channel 202 refers to the dimension of the discharge channel 202 in the vertical direction, and the thickness of the glass slide 400 refers to the dimension of the glass slide 400 in the vertical direction. Exemplarily, the height of the discharge channel 202 is 1 mm to 5 mm greater than the thickness of the glass slide 400.

[0045] In this embodiment, the slide loading device further includes a base 100, on which a second magnetic member 101 is disposed that repels the first magnetic member 301, and the loading box 200 is detachably disposed on the base 100. The first magnetic member 301 and the second magnetic member 101 are configured so that the slide 400 in the discharge channel 202 can weaken the repulsive force between the first magnetic member 301 and the second magnetic member 101 so that the baffle 300 can hold the slide 400.

[0046] For example, when the loading box 200 needs to be loaded, the loading box 200 can be removed from the base 100 first, and the baffle 300 can be slid open.

[0047] Illustratively, after the sample loading box 200 is assembled onto the base 100 , a discharge channel 202 may be formed between the baffle 300 and the sample loading box 200 due to the repulsive action of the second magnetic member 101 and the first magnetic member 301 .

[0048] When the glass slide 400 is pushed into the discharge channel 202, that is, the glass slide 400 is located between the second magnetic member 101 and the first magnetic member 301, the magnetic repulsion between the second magnetic member 101 and the first magnetic member 301 will be weakened, and the baffle 300 slides toward the glass slide 400 under the action of gravity and abuts against the glass slide 400 to form a limiting guide for the glass slide 400, so that the glass slide 400 can be pushed out stably in the horizontal direction, and the upper layer of the glass slide 400 can be prevented from being pushed out together with the current glass slide 400 to ensure the discharge of a single glass slide 400. In addition, the glass slide loading device provided in this embodiment does not need to be installed with a limiting guide component, which effectively improves the compactness and economy of the overall structure of the glass slide loading device. Of course, in order to make the glass slide 400 more stably pushed out in the horizontal direction, a limiting guide component can also be set on the base 100 of the glass slide loading device provided in this embodiment.

[0049] When the glass slide 400 is separated from the discharge channel 202 , the baffle 300 moves upward and resets to the second state position under the action of the magnetic repulsion between the second magnetic attraction member 101 and the first magnetic attraction member 301 .

[0050] Exemplarily, the base 100 can be fixed on a sample loading mechanism of a blood smear preparation instrument, that is, the base 100 can be a part of the sample loading mechanism. The sample loading mechanism is a prior art, and this application will not elaborate on it.

[0051] Exemplarily, a plurality of sample loading boxes 200, for example, two, are provided on the base 100 to ensure that the sample loading mechanism can continuously load the sample glass slide 400, effectively preventing the sample loading mechanism from pausing to load the sample glass slide 400 when the sample loading box 200 is loaded with the glass slide 400, and effectively ensuring the continuous operation of the blood smear preparation instrument. In this embodiment, a plurality of sample loading boxes 200 can be arranged on the base 100 at intervals along the first horizontal direction, wherein the direction b in the figure can be the first horizontal direction. Of course, only one sample loading box 200 can also be provided on the base 100.

[0052] Exemplarily, the second magnetic attraction member 101 may be a permanent magnet or an electromagnet.

[0053] Exemplarily, the first magnetic attraction member 301 may be a permanent magnet.

[0054] In a possible implementation, Figure 5As shown, the baffle 300 is provided with a first folded edge 310 at one end facing the base 100, and a first magnetic attraction member 301 is provided on the first folded edge 310, and the first folded edge 310 can abut against the glass slide 400. The first folded edge 310 can be formed by bending the baffle 300. In this embodiment, when the glass slide 400 is pushed into the discharge channel 202, the baffle 300 can abut against the glass slide 400 through the first folded edge 310, so as to have a sufficiently large contact area with the glass slide 400, so as to prevent the baffle 300 from crushing the glass slide 400.

[0055] Exemplarily, the first magnetic component 301 can be columnar, and a first magnetic component 301 is respectively arranged on both sides of the first folded edge 310 along the width direction of the baffle 300, so as to facilitate the assembly of the first magnetic component 301 onto the baffle 300 and make the magnetic repulsion between the first magnetic component 301 and the second magnetic component 101 moderate. Even if the height of the discharge channel 202 is slightly larger than the thickness of the glass slide 400, when the baffle 300 falls back toward the glass slide 400 in the discharge channel 202, it is not enough to damage the glass slide 400, and the baffle 300 has sufficient squeezing force on the glass slide 400, so that the glass slide 400 can be stably pushed out in the horizontal direction.

[0056] Exemplarily, the second magnetic element 101 may also be columnar and arranged in a one-to-one correspondence with the first magnetic element 301 .

[0057] In a possible implementation, Figure 3 and Figure 6 As shown, the end of the baffle 300 facing away from the base 100 is provided with a second folded edge 320, and the second folded edge 320 can abut against the end of the sample box 200 facing away from the base 100 to limit the baffle 300. In the absence of the magnetic repulsion of the second magnetic attraction member 101, the end of the baffle 300 facing the base 100 just completely blocks the receiving groove 201 to prevent the glass slide 400 from sliding out of the receiving groove 201 during the transportation of the sample box 200. The second folded edge 320 can be formed by bending the baffle 300.

[0058] Exemplarily, the baffle 300 includes a baffle body 330, and the second folding edge 320 includes a first folding edge portion 321 connected to the baffle body 330 and a second folding edge portion 322 connected to the first folding edge portion 321. The baffle body 330 and the first folding edge portion 321 and the first folding edge portion 321 and the second folding edge portion 322 are arranged at an angle. Among them, the baffle body 330 and the first folding edge portion 321 and the first folding edge portion 321 and the second folding edge portion 322 can be perpendicular to each other. In this embodiment, the first folding edge portion 321 is used to abut against one end of the loading box 200 facing away from the base 100, and the first folding edge portion 321 and the second folding edge portion 322 are arranged to facilitate gripping, thereby facilitating the sliding of the baffle 300. Further, the first folding edge 310 is connected to the baffle body 330, and the first folding edge 310 and the baffle body 330 are perpendicular to each other.

[0059] In a possible implementation, Figure 3 and Figure 6 As shown, the baffle 300 is provided with an elongated hole 331, through which the remaining condition of the glass slide 400 in the receiving groove 201 can be observed, so as to realize timely loading of the glass slide 400. Specifically, the elongated hole 331 is provided on the baffle body 330.

[0060] In a possible implementation, Figure 6 As shown, a force-bearing portion 500 is provided on the loading box 200 to facilitate the carrying of the loading box 200. Specifically, the force-bearing portion 500 is provided at one end of the loading box facing away from the base 100, and the force-bearing portion 500 extends along the second horizontal direction toward a side facing away from the discharge side of the loading box and is bent toward the base 100. The c direction in the figure is the second horizontal direction.

[0061] In this embodiment, refer to Figure 6 As shown, the loading box 200 includes a panel 210 and a support seat 220, wherein two panels 210 are provided, and a receiving groove 201 is formed between the two panels 210; the support seat 220 is arranged one-to-one with the panel 210, and the support seat 220 is arranged at one end of the panel 210 facing the base 100, and a stop bar 221 is arranged on the side of the two support seats 220 facing each other, and the stop bar 221 is used to stop the glass slide 400 so that the glass slide 400 is stably placed in the receiving groove 201, and the gap formed between the two stop bars 221 is suitable for the loading mechanism to push the glass slide 400 out of the material. Among them, the two panels 210 are arranged at intervals along the first horizontal direction, and the stop bar 221 is extended along the second horizontal direction. In this embodiment, the receiving groove 201 is formed by enclosing the panels 210 to facilitate the assembly of the loading box 200, and the stop bar 221 is arranged on the support seat 220 to facilitate the molding and manufacturing of the panel 210 and the support seat 220.
