Description

Technical Field

[0001] The utility model relates to the technical field of reagent detection, in particular to a material pushing 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. However, after the material is pushed outside the gene testing device, an external device is required to take the material from the supporting platform of the material pushing device. However, the gene testing device cannot determine whether the external device has taken the material, and the material pushing device needs to be manually retrieved, or a waiting time is set and the material pushing device is retrieved after the time is reached, which will affect the docking efficiency.

[0021] 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.

[0022] The present utility model provides a material pushing device, such as Figure 1 and 2 As shown, including:

[0023] A base 41 on which a slide rail 411 and a drive assembly 44 are disposed;

[0024] A supporting platform 43 is slidably connected to the slide rail 411 and is used to support materials;

[0025] The driving assembly 44 drives the supporting platform 43 to move along the slide rail 411 through the transmission assembly 45;

[0026] The material pushing assembly 46 is connected to the supporting platform 43 and is used to push the material away from the supporting platform 43 .

[0027] Among them, Figure 1 The material pushing device is in the extended state. In this state, the supporting platform 43 moves along the slide rail 411 to one end of the slide rail 411 under the drive of the driving component 44. The supporting platform 43 is extended out of the genetic testing device from the material docking outlet, and the pushing component 46 is in the state of pushing out the material. At this time, the material has been pushed away from the supporting platform 43. Figure 2 The material pushing device is in a retracted state. In this state, the supporting platform 43 moves along the slide rail 411 to the other end of the slide rail 411 under the drive of the driving component 44. The supporting platform 43 is retracted into the genetic testing equipment, and the pushing component 46 is in a retracted state. At this time, the material that needs to be docked can be placed on the supporting platform 43.

[0028] Optionally, the supporting platform 43 includes a slider 432 , and the slider 432 is slidably connected to the slide rail 411 . In this way, the supporting platform 43 can reciprocate along the slide rail 411 under the drive of the driving assembly 44 .

[0029] Optionally, the transmission assembly 45 includes a screw rod, the supporting platform 43 is connected to a nut of the screw rod, and the screw rod of the screw rod is parallel to the slide rail 411 .

[0030] Optionally, the driving assembly 44 includes a motor, and a shaft of the motor is connected to the screw of the lead screw to drive the screw of the lead screw to rotate.

[0031] The shaft of the motor is connected to one end of the lead screw, so that the rotation of the motor drives the screw to rotate, and then converts the rotary motion of the motor into the linear motion of the lead screw nut. Thus, the drive assembly 44 can drive the support platform 43 to move along the slide rail 411, that is, the support platform 43 moves to the end of the slide rail 411 away from the material docking outlet of the genetic testing equipment ( Figure 2 or the supporting platform 43 moves to one end of the slide rail 411 close to the material docking outlet of the gene testing equipment ( Figure 1 status shown in ).

[0032] Optionally, the pushing assembly 46 includes an electric push rod 461 and a pushing head 462 , and the pushing head 462 is connected to the push rod end of the electric push rod 461 .

[0033] Optionally, the supporting platform 43 is provided with a strip hole 431 , and the strip hole 431 is parallel to the electric push rod 461 ; the electric push rod 461 is connected below the supporting platform 43 , and the push head 462 passes through the strip hole 431 from below and extends out of the upper surface of the supporting platform 43 .

[0034] Optionally, the supporting platform 43 includes at least two push rod fixing members 433 , which are arranged on the lower surface of the supporting platform 43 . The push rod fixing members 433 are provided with through holes. The electric push rod 461 is passed through the through holes and fixedly connected to the push rod fixing members 433 .

[0035] The electric push rod 461 is arranged below the supporting platform 43, so that the material pushing device has a compact structure. By providing a strip hole 431 on the supporting platform 43, the push head 462 can extend out of the upper surface of the supporting platform 43, so that the material can be pushed away from the supporting platform 43.

[0036] Optionally, the supporting platform 43 includes limiting protrusions 434 disposed on both sides of the upper surface of the supporting platform 43 , and the limiting protrusions 434 are in the shape of long strips and parallel to the electric push rod 461 .

[0037] There may be two limit protrusions 434, which are respectively arranged on both sides of the supporting platform 43. In this way, when the electric push rod 461 is retracted, the limit protrusion 434 can limit the displacement of the material together with the push head 462, and the limit protrusion 434 is in a long strip shape and parallel to the electric push rod 461, which can control the pushing direction of the material when the electric push rod 461 is pushed out.

[0038] Optionally, the material pushing device also includes a position sensor 471 and a positioning member 472, wherein the position sensor 471 is arranged on the side of the base 41, and the positioning member 472 is correspondingly arranged on the side of the supporting platform 43. When the supporting platform 43 moves to the end of the base 41 away from the pushing direction, the position sensor 471 can detect the positioning member 472.

[0039] Among them, when the genetic testing equipment is turned on, the material pushing device is in a retracted state, or after the material pushing device completes docking with the external equipment, it will return from the extended state to the retracted state. The position sensor 471 is arranged on the side of the base 41, and the positioning member 472 is correspondingly arranged on the side of the supporting platform 43. The position of the position sensor 471 and the position of the positioning member 472 are arranged so that when the material pushing device is in a retracted state, that is, when the supporting platform 43 moves along the slide rail to the end of the base 41 away from the pushing direction, the positioning member 472 can be detected by the position sensor 471. Therefore, if the positioning member 472 is detected by the position sensor 471, it means that the material pushing device is in a retracted state. The position sensor 471 can be an infrared proximity sensor or a micro switch, and the positioning member 472 can be as follows. Figure 1 and 2 The structure is arranged in a sheet shape.
