[0039] Specifically, the sample extraction component 2 is connected to the host 1, and the lower end of the sample extraction component 2 is used to connect the sampling gun head 71. The host 1 is used to control the sample extraction component 2 to move in the vertical direction, and to control the sampling gun head 71 connected to the sample extraction component 2 to absorb or discharge liquid.

[0040] The transfer plate 3 is disposed below the sample extraction component 2, and a plurality of areas for carrying the sample container 5, the subpackaging container 6 and the gun tip container 7 are disposed on the side of the transfer plate 3 facing the sample extraction component 2. The transfer plate 3 is connected to the lateral movement component 4 to realize horizontal movement, so that different areas can be switched to the position corresponding to the sample extraction component 2 through the horizontal movement of the transfer plate 3.

[0041] The working process of the utility model is: when in use, the sample container 5, the subpackaging container 6 and the gun tip container 7 are respectively placed in different areas on the transfer plate 3, the sample container 5 is filled with a sample solution, and the gun tip container 7 is placed with a sampling gun tip 71.

[0042] First, a control signal is sent to the lateral moving component 4 through the controller. Based on the control of the control signal, the lateral moving component 4 drives the transfer plate 3 to move horizontally, so that the area where the gun tip container 7 is located moves to the position corresponding to the sample extraction component 2, that is, the gun tip container 7 is located below the sample extraction component 2. Further, a control signal is sent to the host 1 through the controller. Based on the control of the control signal, the host 1 controls the sample extraction component 2 to move vertically downward, so that the sample extraction component 2 is close to the gun tip container 7, so that its lower end is connected to the sampling gun tip 71 in the gun tip container 7.

[0043] Then, similarly, the sample container 5 is moved to the bottom of the sample extraction component 2 by moving the transfer plate 3, and the host 1 controls the vertical movement of the sample extraction component 2, so that the sampling gun head 71 is extended into the sample solution to aspirate liquid, and the aspirated sample solution is temporarily stored in the sampling gun head 71. Further, the sub-filling container 6 is moved to the bottom of the sample extraction component 2, and the sampling gun head 71 is controlled by the host 1 to discharge liquid, so that the sample solution is successfully dispensed into the sub-filling container 6.

[0044] In actual applications, the host 1 may include a power supply (not shown in the figure), and the power supply is used to power the host 1, the lateral movement component 4 and the controller. The host 1 may be provided with a control button (not shown in the figure), and the control button signal is connected to the controller. The user can control the operation of the host 1 and the lateral movement component 4 by operating the control button. In a specific embodiment, a wireless communication unit whose signal is connected to the controller may be provided, and the wireless communication unit is used to communicate with an external control device, so that wireless control can be performed through the external control device.

[0045] In a specific embodiment, please refer to Figure 3 The host 1 includes a shell 11, and a vertical moving component 12 and a suction and discharge device (not shown in the figure) arranged in the shell 11. The sample extraction component 2 includes a support body 21, and one or at least two extraction components 22 arranged at the lower end of the support body 21. The vertical moving component 12 and the suction and discharge device are both signal-connected to the controller to be controlled by the controller. The support body 21 is connected to the vertical moving component 12, and the vertical moving component 12 is used to control the movement of the support body 21 in the vertical direction. One end of the extraction component 22 away from the support body 21 is used to connect to the sampling gun head 71, and the other end of the extraction component 22 is connected to the suction and discharge device, so that the sampling gun head 71 can realize the suction / discharge of the sample solution based on the suction / discharge function of the suction and discharge device.

[0046] Specifically, refer to Figure 1 and Figure 3Taking the case where there are multiple extraction members 22 as an example, when installing the sampling gun head 71, the support body 21 is driven by the vertical moving component 12 to move vertically downward, close to the gun head container 7 that has been moved into place, and the extraction members 22 correspond one-to-one with the sampling gun heads 71 ​​in the gun head container 7. In the process of the support body 21 moving vertically downward, the end of the extraction member 22 away from the support body 21 is connected to the sampling gun head 71 through an interference fit with the caliber of the sampling gun head 71.

[0047] It can be understood that when aspirating or discharging liquid, based on the fact that the suction and discharge device is connected to the sampling gun head 71 through the extraction member 22, the sampling gun head 71 can perform suction / discharge operations on the sample through the suction and discharge device. Exemplarily, the suction and discharge device can be a pump. Preferably, the suction and discharge device can be connected to the extraction member 22 via a precision valve, so that by controlling the extraction pressure of the suction and discharge device itself and cooperating with the precision valve, precise control of the amount of liquid aspirated can be achieved. In addition, exemplarily, the packaging container 6 can have a plurality of small grids for dispensing sample solutions, and the small grids also correspond one-to-one with the extraction member 22, so that the sample solution temporarily stored in the extraction member 22 is discharged into the corresponding small grids when discharging liquid.

[0048] Further, please refer again to Figure 3 A gun removal plate 23 for removing the sampling gun head 71 is also provided on the side of the support body 21 facing the extraction member 22, and the extraction member 22 passes through the gun removal plate 23 and is provided on the lower side of the support body 21. A driving device 24 whose signal is connected to the controller is provided in the support body 21, and the driving device 24 is drivingly connected to the gun removal plate 23, so as to drive the gun removal plate 23 to move in the vertical direction. When removing the sampling gun head 71, the gun removal plate 23 moves in the vertical direction under the drive of the driving device 24, and the sampling gun head 71 is separated from the extraction member 22 by pushing the sampling gun head 71.

[0049] In a specific embodiment, the vertical moving assembly 12 may include: a screw 121, a screw nut 122, a first connecting member 123 and a lifting motor 124 whose signal is connected to the controller.

[0050] Please refer to Figures 3 to 5 Specifically, the screw rod 121 is arranged in the housing 11 along the vertical direction, the screw nut 122 is threadedly connected to the screw rod 121, and the lifting motor 124 is arranged on one side of the screw rod 121 and is connected to the screw rod 121 through transmission. The support body 21 is connected to the screw nut 122 through the first connecting member 123 to achieve vertical movement with the screw nut 122. When in use, the screw rod 121 is driven to rotate by the lifting motor 124, and the rotation of the screw rod 121 drives the screw nut 122 to move in the direction of the screw rod 121, so that the first connecting member 123 connected to the screw nut 122 drives the support body 21 to move vertically. In other embodiments, the vertical movement component 12 also drives the support body 21 to move vertically by means of a conveyor belt drive or a chain drive.

[0051] Please refer to Figure 1 On the basis of the above embodiment, further, a vertical through slot 111 is provided on one side of the housing 11, and one end of the first connecting member 123 away from the screw nut 122 extends out through the vertical through slot 111 and is connected to the support body 21. It can be understood that during the vertical movement of the support body 21 and the first connecting member 123, the vertical movement can be limited by the first connecting member 123 abutting against the end of the vertical through slot 111.

[0052] and / or, refer to Figure 4 A vertical guide rail 112 is provided on the inner wall of the housing 11, and one end of the first connecting member 123 is slidably connected to the vertical guide rail 112. On the one hand, the vertical guide rail 112 can play a guiding role, and on the other hand, the first connecting member 123 can also limit the vertical movement by abutting against the end of the vertical guide rail 112. Exemplarily, the number of the vertical guide rails 112 is 2.

[0053] In a specific embodiment, the lateral movement assembly 4 includes: a housing 41, and a conveyor belt 42, a first transmission wheel 43, a second transmission wheel 44, a second connecting member 45 and a lateral movement motor 46 whose signal is connected to the controller.

[0054] Please refer to Figure 3 and Figure 6 Specifically, the lateral movement motor 46 is connected to the first transmission wheel 43 or the second transmission wheel 44, and the first transmission wheel 43 and the second transmission wheel 44 are connected to each other through the conveyor belt 42. The transfer plate 3 is arranged above the housing 41, and a guide slot 411 corresponding to the conveyor belt 42 is provided on the side of the housing 41 facing the transfer plate 3. One end of the second connecting member 45 is connected to the conveyor belt 42, and the other end of the second connecting member 45 extends out of the outside through the guide slot 411 and is connected to the transfer plate 3. When in use, the first transmission wheel 43 or the second transmission wheel 44 is driven to rotate by the lateral movement motor 46, and the conveyor belt 42 is driven by the first transmission wheel 43 and the second transmission wheel 44 to move horizontally, and the conveyor belt 42 then drives the second connecting member 45 to move synchronously, and the second connecting member 45 drives the transfer plate 3 to achieve horizontal movement. In other embodiments, the lateral movement component 4 also drives the transfer plate 3 to move horizontally by means of a screw drive or a chain drive.

[0055] Furthermore, the lower part of the housing 11 of the host 1 may have a base 113, the housing 41 of the lateral movement assembly 4 may be disposed on the base 113, and the lower part of the base 113 may also be provided with an anti-skid pad 114. It can be understood that the utility model has a higher stability through the integrated design (the housing 41 is disposed on the base 113) and the provision of the anti-skid pad 114.

[0056] In a specific embodiment, please refer to Figure 1 and Figure 2 The transfer plate 3 is also provided with a limiting frame 31 for limiting the sample container 5, the sub-packaging container 6 and the gun tip container 7. In practical applications, the structure of the limiting frame 31 can be set according to the structural adaptability of each container. It can be understood that the limiting frame 31 can prevent the displacement of each container during the movement of the transfer plate 3, thereby preventing the displacement of the container from affecting the installation of the sampling gun tip 71 or the suction / discharge of the sample solution.

[0057] In a specific embodiment, please refer to Figure 2 One or more sides of the housing 11 of the host 1 are also provided with heat dissipation holes 115. The provision of the heat dissipation holes 115 improves the heat dissipation performance of the device and increases the service life of the device.

[0058] In summary, the sample dispensing instrument of the utility model realizes the functions of automatically installing the sampling gun head 71 and automatically dispensing samples based on the host 1 controlling the vertical movement of the sample extraction component 2, the host 1 controlling the sampling gun head 71 connected to the sample extraction component 2 to absorb or discharge liquid, and the lateral movement component 4 controlling the horizontal movement of the transfer plate 3, which has higher efficiency and higher accuracy than traditional manual dispensing.
