[0025] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many other forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] like Figure 1 As shown, in one embodiment of a staining mechanism, the staining mechanism includes a frame 1, a detection assembly, and a transport assembly. The frame 1 is provided with a groove 12 to accommodate a glass slide 100 and provide a staining area for the glass slide 100. The detection assembly includes an emitting element 2 and a receiving element 3, which are spaced apart. The groove 12 is located between the emitting element 2 and the receiving element 3. The emitting element 2 is used to emit light, and the receiving element 3 is used to receive the light. When the glass slide 100 is located in the groove 12, the light can pass through the glass slide 100. The transport assembly is in communication with the receiving element 3 and is used to remove the glass slide 100 from the groove 12 when the receiving element 3 receives light that has passed through the glass slide 100.

[0029] In this embodiment, by setting up the transmitting element 2 and the receiving element 3, it is possible to detect whether there is a glass slide 100 in the groove 12. If a glass slide 100 is detected, the glass slide 100 is further removed by the transport component. When no glass slide 100 is detected, the transport component will not move. The entire detection process is fast, which solves the technical problem of low initialization efficiency of the existing staining mechanism.

[0030] Specifically, the emitting element 2 can be a structure such as a laser emitter, a diode, etc. that can emit linear light, and the receiving element 3 can be a combination of a receiving photodiode and a photoelectric conversion circuit. It can be understood that when light passes through the glass slide 100, it will affect the reception of the receiving element 3. The light is converted into an electrical signal U1. The receiving element 3 can set a threshold. When U1 is greater than the threshold, it means that there is no glass slide 100 in the groove 12. When U1 is less than the threshold, it means that there is a glass slide 100 in the groove 12.

[0031] In an embodiment of a staining mechanism, a plurality of partitions 13 are provided on the inner wall of the groove 12, and each of the partitions 13 is arranged at intervals along the direction of the light so as to be able to separate a plurality of sub-grooves in the groove 12 along the direction of the light, and each of the sub-grooves is used to accommodate each of the glass slides 100 in a one-to-one correspondence.

[0032] In this embodiment, by setting the partition 13, several separation spaces can be formed, each of which can be used to place the glass slide 100, that is, each glass slide 100 can be separated and stained separately, so that multiple glass slides 100 can be stained at one time, thereby improving the staining efficiency.

[0033] In an embodiment of the dyeing mechanism, there are multiple grooves 12, and the grooves 12 are arranged at intervals along the direction of the light.

[0034] In this embodiment, by providing a plurality of grooves 12 , it is also possible to accommodate a plurality of glass slides 100 , thereby increasing the number of glass slides 100 that can be stained at one time and improving the staining efficiency.

[0035] In an embodiment of the dyeing mechanism, a channel connected to the groove 12 is opened on the frame 1, and the channel can discharge the liquid in the groove 12. The dyeing mechanism also includes a valve 14, which is installed on the frame 1 and is used to control the opening and closing of the outflow channel.

[0036] In this embodiment, it is understood that dyeing requires the use of a dyeing liquid, and the dyeing liquid needs to be filled into the groove 12. In this embodiment, by providing a channel and a valve 14, it is convenient for the user to discharge the dyeing liquid from the groove 12. Specifically, the valve 14 can be a manual or electromagnetic control valve.

[0037] Furthermore, an inlet can be added at the bottom of the corresponding groove 12 to communicate with the groove 12. A valve is also installed at the inlet to communicate with the container filled with dyeing liquid through the valve and the inlet, so that the dyeing liquid can automatically enter the groove 12.

[0038] In one embodiment of the dyeing mechanism, the transport assembly includes a transport element, a first driver, a conveying element, and a second driver. The frame 1 is provided with a discharge area in the path of the light, and the transport element is located in the discharge area. The driving end of the first driver is connected to the transport element and is used to drive the transport element toward or away from the discharge area. The output end of the second driver is connected to the conveying element and is used to drive the conveying element to move in the direction of the light. The conveying element is used to transport the slide 100 to the discharge area.

[0039] In this embodiment, by setting up a handling element and a conveying element, docking can be more convenient. The conveying element is used to send the glass slide 100 in the groove 12 to the unloading area for the handling element to move away, and the handling element can place the glass slide 100 outside the dyeing mechanism, such as a recycling box. With this setting, the process of moving the glass slide 100 is optimized, and a detailed division of labor is carried out, which can improve the efficiency of transportation.

[0040] Specifically, both the first and second drive elements can be linear drive modules, such as pneumatic cylinders, hydraulic cylinders, or linear motors. Alternatively, they can be dual-axis drive modules composed of two linear drive modules, i.e., two linear modules positioned at an angle. This facilitates control of the positions of the handling and conveying elements. Both the handling and conveying elements can be pneumatic fingers or robotic arm components.

[0041] In addition, it should be noted that the positions on the rack 1 are divided, for example, each groove 12 corresponds to an area, and the conveying element can reach each area in turn under the drive of the second driving member, and then the conveying element clamps each area, so that all glass slides 100 can be removed from the groove 12 without omission.

[0042] In an embodiment of the dyeing mechanism, the frame 1 includes multiple sub-frames 11, and each sub-frame 11 is connected end to end in sequence along the direction of the light. The emitting element 2 is arranged at the sub-frame 11 at the head end, and the receiving element 3 is arranged at the sub-frame 11 at the tail end.

[0043] In this embodiment, similar to the previous embodiment, by connecting multiple sub-racks 11 end to end, it is possible to detect whether there are glass slides 100 in the grooves 12 on multiple sub-racks 11 at one time during the detection process, thereby improving the detection efficiency and further increasing the capacity of glass slides 100 in staining.

[0044] In an embodiment of the staining mechanism, there are multiple emitting elements 2 and receiving elements 3 , which are arranged in a one-to-one correspondence to form an independent detection group, and each detection group is used to detect the glass slide 100 in the groove 12 .

[0045] In this embodiment, by setting up multiple transmitting elements 2 and multiple receiving elements 3, detection can be performed more accurately, accuracy can be improved, and non-detection due to the placement posture of the glass slide 100, such as tilt, can be avoided. The light rays of multiple detection groups are parallel and arranged at intervals, for example, a matrix-like arrangement can be formed.

[0046] In an embodiment of the dyeing mechanism, the dyeing mechanism further includes a first bracket 4 , the first bracket 4 is connected to the frame 1 , and the emitting element 2 is installed on the first bracket 4 .

[0047] In this embodiment, the first bracket 4 can be an L-shaped plate-like structural member. The emitting element 2 can be placed outside the frame 1 through the first bracket 4, thereby reducing the space occupied on the frame 1 and facilitating installation on the existing frame 1. The existing frame 1 has many grooves 12 and lacks space. By providing the first bracket 4, it is possible to avoid occupying space, solve adaptability, and there is no need to remake the frame 1.

[0048] In an embodiment of the dyeing mechanism, the dyeing mechanism further includes a second bracket 5 , the second bracket 5 is connected to the frame 1 , and the receiving element 3 is installed on the second bracket 5 .

[0049] In this embodiment, the second bracket 5 can be an L-shaped plate-like structural member. The receiving element 3 can be placed outside the frame 1 through the second bracket 5, thereby reducing the space occupied on the frame 1 and facilitating installation on the existing frame 1. The existing frame 1 has many grooves 12 and lacks space. By providing the second bracket 5, it is possible to avoid occupying space, solve the adaptability problem, and there is no need to remake the frame 1.

[0050] The utility model also relates to a blood smear preparation instrument, which comprises the dyeing mechanism in the above embodiment.

[0051] By adopting the above-mentioned staining mechanism, the blood smear preparation instrument can quickly detect the glass slide 100 during initialization. When there is no glass slide 100, there is no need to clear it, which saves time and improves initialization efficiency.

[0052] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
