Description

Technical Field

[0001] The utility model relates to the technical field of reagent detection, in particular to a material docking device. Background Art

[0002] Genetic testing equipment needs to perform the relevant steps of genetic testing in an internal closed space. When the genetic testing equipment needs to be docked with external equipment, some materials need to be pushed out from the inside of the genetic testing equipment in order to complete the docking with the external equipment. For example, the material can be a PCR plate, which is a carrier that mainly participates in the amplification reaction of primers, Taq DNA polymerase, dNTP, template nucleic acid, Mg, buffer, etc. in the polymerase chain reaction (PCR). In addition, the material can also be a deep well plate, a gun tip box, an adapter, etc.

[0003] In the prior art, a material pushing device is provided in the gene testing device to push the material to an external device outside the gene testing device. This often requires the provision of a material pushing device with a longer push rod so as to achieve the material docking with the external device. However, the demand for integration and miniaturization of gene testing equipment is increasing, and a material pushing device with a long push rod will occupy a larger internal area, which is not conducive to improving the integration of gene testing equipment.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0024] The present utility model embodiment provides a material docking device, such as Figure 1-4 As shown, including:

[0025] A base 1, on which a first slide rail 11 is arranged;

[0026] The middle frame 2 is slidably connected to the first slide rail 11, and is provided with a second slide rail 21 and a driving assembly 4;

[0027] A supporting platform 3, slidably connected to the second slide rail 21, for supporting materials;

[0028] The driving assembly 4 drives the middle frame 2 via the first transmission assembly 5 , and drives the supporting platform 3 via the second transmission assembly 6 , so as to drive the middle frame 2 and the supporting platform 3 to move in the same direction relative to the base 1 .

[0029] Among them, Figure 1 The state of the material docking device shown is an extended state. In this state, the supporting platform 3 is extended out of the gene detection equipment, so that the material can be docked with the external equipment. Figure 1 In the extended state shown in FIG. 1 , the middle frame 2 is driven by the driving assembly 4 to move along the first slide rail 11 to one end of the first slide rail 11 , and the supporting platform 3 is also driven by the driving assembly 4 to move along the second slide rail 21 to one end of the second slide rail 21 . Figure 2 The material docking device is in a retracted state. In this state, the supporting platform 3 is retracted into the gene detection device. Figure 2 As shown, the middle frame 2 moves along the first slide rail 11 to the other end of the first slide rail 11 under the drive of the driving assembly 4, so that the middle frame 2 overlaps with the base 1, and the supporting platform 3 also moves along the second slide rail 21 to the other end of the second slide rail 21 under the drive of the driving assembly 4. In the retracted state, the supporting platform 3 can receive materials in the genetic testing equipment that need to be docked with the outside, and in this state, it can be directly reflected that the material docking device is very compact and occupies a small area.

[0030] Optionally, the middle frame 2 includes a first slider 22 , and the first slider 22 is slidably connected to the first slide rail 11 . In this way, the middle frame 2 can reciprocate along the first slide rail 11 under the drive of the driving assembly 4 .

[0031] Optionally, the supporting platform 3 includes a second slider 32 , and the second slider 32 is slidably connected to the second slide rail 21 . In this way, the supporting platform 3 can reciprocate along the second slide rail 21 under the drive of the driving assembly 4 .

[0032] It should be noted that the driving component 4 drives the middle frame 2 through the first transmission component 5 and drives the supporting platform 3 through the second transmission component 6. Therefore, the driving component 4 can synchronously drive the middle frame 2 and the supporting platform 3 to move, that is, the middle frame 2 and the supporting platform 3 approach the base 1 together (until the retracted state) or move away from the base 1 (until the extended state). In this way, one driving component 4 can be used to drive the middle frame 2 and the supporting platform 3 to move at the same time, reducing the number of driving components. Moreover, the middle frame 2 and the supporting platform 3 move in the same direction at the same time, which also improves the conversion efficiency between the retracted state and the extended state, which is beneficial to the docking of the genetic testing equipment with external equipment.

[0033] Optionally, the supporting platform 3 includes a limiting protrusion 33, which is arranged on the upper surface of the supporting platform 3 and is used to limit the position of the material.

[0034] Among them, a plurality of limiting protrusions 33 are provided corresponding to the size and shape of the material. When the material is transferred to the supporting platform 3, the material is placed between the plurality of limiting protrusions 33, so that when the material docking device changes from the retracted state to the extended state, the material will not be displaced significantly on the upper surface of the supporting platform 3, so that when docking with external equipment, the docking will not be poor due to the misalignment of the material. For example, Figure 1 In the embodiment, an L-shaped limiting protrusion is arranged on a corner of the supporting platform 3, a pair of mutually perpendicular strip protrusions are arranged in the diagonal direction of the L-shaped limiting protrusion, and point protrusions can also be arranged in the directions of the two sides of the L-shaped limiting protrusion.

[0035] Optionally, the driving assembly 4 includes a dual-output shaft motor.

[0036] Optionally, the first transmission assembly 5 includes a first gear 51 and a first rack 52 that mesh with each other; the first gear 51 is connected to one end of the shaft of the double-output shaft motor, and the first rack 52 is fixedly connected to the base 1 and parallel to the first slide rail 11.

[0037] Optionally, the second transmission assembly 6 includes a second gear 61 and a second rack 62 that mesh with each other; the second gear 61 is connected to the other end of the shaft of the double-output shaft motor, and the second rack 62 is fixedly connected to the supporting platform 3 and parallel to the second slide rail 21.

[0038] In the retracted state, the supporting platform 3, the middle frame 2 and the base 1 are stacked. In order to realize that one driving assembly drives the movement of the supporting platform 3 and the middle frame 2 at the same time, a double-shaft motor is used and the motor shaft is arranged vertically. The first transmission assembly 5 and the second transmission assembly 6 can be placed at the upper and lower ends of the double-shaft motor respectively, which is convenient for the arrangement of the first transmission assembly 5 and the second transmission assembly 6 and reduces the interference between the transmission assemblies. Gears and racks are used as an optional implementation method. In addition, other transmission assembly forms such as screws can also be selected to convert the rotational motion of the motor shaft into the linear motion of the supporting platform 3 and the middle frame 2.

[0039] Optionally, the first slide rail 11 is parallel to the second slide rail 21 .

[0040] Optional, such as Figure 3 and 4 The material docking device also includes a position sensor 71 and a positioning member 72. The position sensor 71 is arranged on the side of the base 1, and the positioning member 72 is correspondingly arranged on the side of the supporting platform 3. When the middle frame 2 and the supporting platform 3 move to above the base 1, the position sensor 71 can detect the positioning member 72.

[0041] Among them, the material docking device is in a retracted state when the genetic testing equipment is turned on, or after the material docking device completes docking with the external device, it will return from the extended state to the retracted state. The position sensor 71 is arranged on the side of the base 1, and the positioning member 72 is correspondingly arranged on the side of the supporting platform 3. The position of the position sensor 71 and the position of the positioning member 72 are arranged so that when the material docking device is in a retracted state, that is, when the middle frame 2 and the supporting platform 3 are moved to above the base 1, the positioning member 72 can be detected by the position sensor 71. Therefore, if the positioning member 72 is detected by the position sensor 71, it means that the material docking device is in a retracted state. The position sensor 71 can be an infrared proximity sensor or a micro switch, and the positioning member 72 can be as follows. Figure 4 The structure is arranged in a sheet shape.

Unless otherwise specified, the directional words used, such as "up", "down", "left", "right", "inside" and "outside", are used for ease of understanding and therefore do not constitute limitations on the protection scope of the present utility model.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
