Referring to fig. 3, fig. 4 and fig. 5, fig. 4 is a schematic perspective view of the slide unit 11 in fig. 2, and fig. 5 is a schematic front view of the slide 120 in fig. 4.

The slide unit 11 includes a slide driving mechanism 111 and a slide mounting mechanism 112, wherein the slide mounting mechanism 112 is used for mounting the slide 110, and the slide driving mechanism 111 is connected with the slide mounting mechanism 112 to drive the slide 110 to coat a sample on the slide 120 so as to form a smear.

Specifically, the slide 120 includes a coating start end 120a and a coating end 120b, the push plate 110 is configured to sequentially coat the sample from the coating start end 120a to the coating end 120b, that is, in practical application, the slide 120 includes a coating area E, the coating start end 120a is one end of the coating area E, the coating end 120b is the other end of the coating area E, and the push plate 110 is configured to coat the sample on the coating area E of the slide 120 from the coating start end 120a to the coating end 120b in the sample coating process.

In this embodiment, the pusher driving mechanism 111 includes a first pusher driving component 1111 and a second pusher driving component 1112, the first pusher driving component 1111 is connected to the pusher mounting mechanism 112, the second pusher driving component 1112 is connected to the first pusher driving component 1111, so that the first pusher driving component 1111 drives the pusher 120 to move in a direction D as shown in fig. 4, the second pusher driving component 1112 drives the pusher 120 to move in a direction a as shown in fig. 4, so as to complete the pusher operation, in which the direction a is a horizontal direction and the direction D is a vertical direction in the embodiment, in which in practical application, the first pusher driving component 1111 drives the pusher 120 to move in the direction D to a pushable position, and then the second pusher driving component 1112 drives the pusher 120 to apply a sample to the slide 120 in the direction a.

Alternatively, in the present embodiment, the first pusher driving assembly 1111 and the second pusher driving assembly 1112 are both driven by a screw motor, and in other embodiments, other driving methods, such as a cylinder, may be used, which is not limited thereto.

Referring to fig. 3, 5, 6 and 7, fig. 6 is an exploded structure of the drying unit 12 in fig. 2, and fig. 7 is a position diagram of another embodiment of the blower mechanism 121 in fig. 3, wherein the drying unit 12 includes the blower mechanism 121.

The air blowing mechanism 121 is configured to blow air to the smear in a first direction B, and as shown in fig. 5, a projection direction B1 of the first direction B on the slide plane M is opposite to a second direction C in which the slide 120 extends from the coating start end 120a to the coating end 120B.

As shown in fig. 3 and fig. 7, in a specific application scenario, the slide device 10 includes a slide region R1 and a drying region R2, the slide unit 11 is disposed in the slide region R1, the air supply mechanism 121 is disposed in the drying region R2, and the drying region R2 is disposed at a side of the slide region R1 facing the moving direction a of the slide 110 for coating the sample, so that the air supply mechanism 121 blows air to the smear in a first direction B of the drying region R2 facing the slide region R1.

Specifically, when the slide 110 is in a horizontal state in the process of coating the sample on the slide 120 in the moving direction a of the coated sample, and after the coating is completed, the slide 120 is still in a horizontal state in the process of blowing the air supply mechanism 121 to the slide, it can be understood that in this case, the moving direction a of the coated sample of the slide 110 and the second direction C are in the same direction, and in this way, compared with the way of turning the slide to a vertical state and then blowing the air in the prior art, the sample can be prevented from being blown to the bottom of the slide under the action of gravity, thereby avoiding the occurrence of moire and avoiding affecting the smear effect.

Referring to fig. 2, fig. 8 and fig. 9 together, fig. 8 is a schematic view illustrating a position of another embodiment of the drying unit and the slide in fig. 2, and fig. 9 is a schematic view illustrating a position of another embodiment of the drying unit in fig. 8, in another specific application scenario, the slide pushing device 10 further includes a turnover unit 13, the turnover unit 13 is used for turning over the smear, and the air supply mechanism 121 is used for blowing air to the smear after the smear is turned over.

Specifically, when the slide 110 applies the sample to the slide 120 in the moving direction a of the sample, the slide 120 is in a horizontal state, and after the application, the turnover unit 13 turns the smear from the horizontal state to the vertical state, and then the air supply mechanism 121 blows air to the smear, in this way, since the projection direction B1 of the first direction B on the slide plane M is opposite to the second direction C, that is, as shown in fig. 8 and 9, the air supply mechanism 121 blows air from bottom to top, so that the wind direction of the air supply mechanism 121 is opposite to the gravity direction of the sample, thereby avoiding the sample from being blown to the bottom of the slide, avoiding the occurrence of moire, and further affecting the smear effect.

It will be appreciated that when the first direction B is opposite to the second direction C as shown in fig. 3 or 8, then the projection direction B1 is the same direction as the first direction B, i.e. the angle alpha=180° between the first direction B and the second direction C, as shown in fig. 7 or 9, when the first direction B is obliquely arranged relative to the second direction C, the included angle α between the first direction B and the second direction C is 90 ° < α < 180 °, and in specific applications, α may be 135 ° -180 °, where α may be a specific value, and of course, may be set according to actual needs, which is not limited.

Optionally, the distance L between the air supply mechanism 121 and the smear in the first direction B satisfies: l is more than or equal to 40mm and less than or equal to 100mm.

Further, the air supply mechanism 121 in this embodiment is adjustable, so as to adjust the air supply angle and/or the air supply distance of the air supply mechanism 121 relative to the smear, for example, the air supply angle and/or the air supply distance of the air supply mechanism 121 relative to the smear can be adjusted according to the type of different samples or the coating thickness of the samples coated on the slide, so as to adjust the air volume and the wind power of the air supply mechanism 121 blown to the smear, thereby achieving the best air supply effect.

Specifically, since the blowing angle is related to the parameters of the blower, for example, whether the sample is a body fluid sample or a blood sample, and the viscosity of the sample is what is the viscosity of the sample, if the sample is a blood sample, what is the HGB value of the sample can be achieved by adjusting different blowing angles according to the preset parameter correspondence, so as to achieve the optimal blowing effect on the smear.

Further, the drying unit 12 in the present embodiment further includes a heating mechanism 122, and the heating mechanism 122 is disposed on a side of the air supply mechanism 121 facing the first direction B, so that the air blown by the air supply mechanism 121 to the smear is hot air, and drying efficiency is improved.

The turnover unit 13 turns over the smear in the carrying mechanism 141 by turning over the carrying mechanism 141, the carrying mechanism 141 and the turnover unit 13 are both connected with the conveying driving mechanism 142 to drive the carrying mechanism 141 and the turnover unit 13 to move, a smear position P1 is provided along a movement track of the carrying mechanism 141, and the smear driving mechanism 111 is used for driving the smear 110 to coat the sample on the slide 120 at the smear position P1 to form a smear.

When the carrying mechanism 141 is placed horizontally, the slide 120 enters from the side, and since the opening of the mounting groove 101 is arranged on the side of the carrying mechanism 141, when the carrying mechanism 141 is turned over by the turning unit 13, the slide 120 can be prevented from falling as long as the opening is placed upwards, and the turning unit 13 can rotate the carrying mechanism 141 to adjust the angle between the slide 120 and the first direction B in the carrying mechanism 141, so as to achieve the optimal blowing effect. In addition, the turnover unit 13 can also vertically set the dried smear, so that the clamping jaw and the slide are conveniently transferred into a subsequent processing mechanism for processing.

In one embodiment shown in fig. 3, the blade position P1 is disposed on the air blowing path of the air blowing mechanism 121, so that the air blowing mechanism 121 blows air to the smear on the blade position P1, that is, after the blade driving mechanism 111 drives the blade 110 to apply the sample on the slide 120 at the blade position P1 to form the smear, the conveying driving mechanism 142 does not operate, the smear remains at the blade position P1, and then the air blowing mechanism 121 starts blowing air to the smear, however, although in fig. 3, the air blowing direction of the air blowing mechanism 121, that is, the first direction B is opposite to the second direction C, the air blowing direction B of the air blowing mechanism 121 may be inclined with respect to the second direction C as shown in fig. 7.

In another embodiment shown in fig. 7, a drying position P2 is further provided along the movement track of the carrying mechanism 141, the drying position P2 is disposed on the blowing path of the air blowing mechanism 121, and the conveying driving mechanism 142 is used to drive the smear from the pusher position P1 to the drying position P2, so that the air blowing mechanism 121 blows air to the smear on the drying position P2, that is, after the pusher driving mechanism 111 drives the pusher 110 to apply the sample on the slide 120 at the pusher position P1 to form the smear, the conveying driving mechanism 142 drives the smear from the pusher position P1 to the drying position P2, and then the air blowing mechanism 121 starts blowing air to the smear, however, although in fig. 7, the blowing direction of the air blowing mechanism 121, that is, the first direction B is disposed obliquely with respect to the second direction C, in this case that the air blowing mechanism 121 blows air to the smear on the drying position P2, that the blowing direction B of the air blowing mechanism 121 may be opposite to the second direction C as shown in fig. 3.

Further, when the second direction B is disposed obliquely with respect to the second direction C as shown in fig. 7, in an alternative application scenario, the conveying driving mechanism 142 is configured to drive the smear to move along the second direction C, so that the air blowing mechanism 121 sequentially blows air to a plurality of areas of the smear along the third direction F, which is opposite to the second direction C.

Specifically, in practical application, it may occur that the air blown by the air blowing mechanism 121 cannot cover the entire area of the smear, or even if the entire area of the smear is covered, the air volume of the area at the edge of the smear is small, so that the smear cannot be completely dried, and therefore, when the air blowing mechanism 121 blows air toward the smear, at an initial stage, only a partial area of the smear may be blown, and then the conveying driving mechanism 142 drives the smear to move in the second direction C, so that the air blowing mechanism 121 sequentially blows air to a plurality of areas of the smear in the third direction F until the smear is completely dried.

In another optional application scenario, the drying unit 12 further includes a drying driving mechanism (not shown in the figure), where the drying driving mechanism is connected to the air supply mechanism 121 to drive the air supply mechanism 121 to move along the third direction F, so that the air supply mechanism 121 sequentially blows air to a plurality of areas of the smear along the third direction F, and the principle is the same as that of the above-mentioned specific application scenario, and will not be repeated here.
