Compared with the prior art, the invention has the following beneficial effects:

in the reaction tube grabbing and mixing device and the analyzer, when the liquid in the reaction tube needs to be mixed uniformly, the first driving mechanism drives the clamping device 1 to move downwards, after the gripper clamps the reaction tube, the first driving mechanism drives the clamping device 1 to move upwards to enable the reaction tube to be separated from the working position of the reaction tube and to be located above the working position, and then the second driving mechanism of the mixing device drives the gripper to axially rotate around the axis of the second driving mechanism, so that the liquid in the reaction tube is mixed uniformly. After the liquid mixing is finished, when the first driving mechanism drives the clamping device to descend so that the bottom of the reaction tube is close to the bottom of the working position, the third driving mechanism drives the push rod to move downwards, the push rod pushes the reaction tube to continue to move downwards, meanwhile, the first driving mechanism drives the clamping device to move upwards, and the reaction tube can be stably placed to the working position under the action of the push rod.

According to the invention, the push rod device and the blending device are arranged and respectively operate the reaction tube without mutual interference. Because the reaction tube is coaxially fixed on the hand grip, the reaction tube can directly axially rotate along with the hand grip, and the uniform mixing of the liquid in the reaction tube can be completed without other modes (such as centrifugation and friction rolling), so that the action amplitude in the liquid uniform mixing process is reduced, and the liquid is prevented from splashing out of the reaction tube. Meanwhile, the reaction tube can be uniformly mixed only by separating from the working position above the working position, and the reaction tube does not need to be moved to a uniformly mixing device, so that the overall service time of tube grabbing, uniformly mixing and tube placing is shortened. In addition, the reaction tube only has the top to contact the gripper and the push rod, and the reaction tube is free of contact inside, so that pollution to the reaction tube is prevented, and the experimental result is more accurate.

In conclusion, the reaction tube grabbing and mixing device can shorten the operation time of the reaction tube, improve the mixing effect of liquid in the reaction tube, and simultaneously prevent the liquid from splashing out of the reaction tube and polluting the reaction tube.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

On one hand, the invention provides a reaction tube grabbing and mixing device, as shown in fig. 1 to 4, comprising a clamping device 1, a mixing device 2, a push rod device 3 and a first driving mechanism 4 for driving the clamping device 1 to move up and down, wherein,

the clamping device 1 comprises a gripper 1-1, and a through hole 1-1-1 for placing a reaction tube is formed in the gripper 1-1;

the blending device 2 comprises a second driving mechanism 2-1 for driving the gripper 1-1 to rotate;

the push rod device 3 comprises a push rod 3-1 which is arranged in a through hole 1-1-1 of the gripper 1-1 in a sliding mode and a third driving mechanism 3-5 which is used for driving the push rod 3-1 to move downwards or up and down.

In the reaction tube grabbing and mixing device, when liquid in a reaction tube needs to be mixed uniformly, the first driving mechanism 4 drives the clamping device 1 to move downwards, after the gripper 1-1 clamps the reaction tube, the first driving mechanism 4 drives the clamping device 1 to move upwards to enable the reaction tube to be separated from the working position of the reaction tube and to be located above the working position, and then the second driving mechanism 2-1 of the mixing device 2 drives the gripper 1-1 to axially rotate around the axis of the gripper 1-1, so that the liquid in the reaction tube is mixed uniformly. After the liquid is mixed uniformly, the first driving mechanism 4 drives the clamping device 1 to descend so that the bottom of the reaction tube is close to the bottom of the working position, the third driving mechanism 3-5 drives the push rod 3-1 to move downwards, the push rod 3-1 pushes the reaction tube to continue to move downwards, meanwhile, the first driving mechanism 4 drives the clamping device 1 to move upwards, and the reaction tube can be stably placed to the working position under the action of the push rod 3-1.

According to the invention, the push rod device 3 and the blending device 2 are arranged, and the two devices respectively operate the reaction tube without interfering with each other. Because the reaction tube is coaxially fixed on the gripper 1-1, the reaction tube can directly axially rotate along with the gripper 1-1, and the liquid in the reaction tube can be uniformly mixed without other modes (such as centrifugation and friction rolling), so that the action amplitude in the liquid uniformly mixing process is reduced, and the liquid is prevented from splashing out of the reaction tube. Meanwhile, the reaction tube can be uniformly mixed only by separating from the working position above the working position, and the reaction tube does not need to be moved to the uniformly mixing device 2, so that the overall service time of tube grabbing, uniformly mixing and tube placing is shortened. In addition, the reaction tube only has the top contacting the gripper 1-1 and the push rod 3-1, and the interior is not contacted, so that the pollution to the reaction tube is prevented, and the experimental result is more accurate.

In conclusion, the reaction tube grabbing and mixing device can shorten the operation time of the reaction tube, improve the mixing effect of liquid in the reaction tube, and simultaneously prevent the liquid from splashing out of the reaction tube and polluting the reaction tube.

In an embodiment of the present invention, the through hole 1-1-1 of the gripper 1-1 is a tapered hole at the lower end thereof, the diameter of the lower end of the tapered hole is smaller than the diameter of the upper end, and the diameter of the lower end is smaller than the diameter of the top end of the reaction tube, thereby ensuring that the gripper 1-1 can grip the reaction tube. In addition, a plurality of uniformly distributed open grooves 1-1-2 can be formed in the lower end face of the hand grip 1-1 along the axial direction, and oblique angles 1-1-3 are formed in the lower end face of the through hole 1-1-1. When the gripper 1-1 grips the reaction tube in the downward movement process, the top end of the reaction tube can smoothly enter the tapered hole and be tightly clamped in the gripper 1-1 under the assistance of the open slot 1-1-2 and the bevel 1-1-3.

In addition, the diameter of the lower end of the push rod 3-1 needs to be larger than that of the lower end of the tapered hole and smaller than that of the upper end of the tapered hole, so that the push rod 3-1 can be ensured to push the reaction tube out of the gripper 1-1, and the gripper 1-1 can be prevented from being deformed due to the arrangement of the open slot 1-1-2.

In an embodiment of the invention, the blending device 2 further preferably comprises a blending platform 2-2, wherein the second driving mechanism 2-1, the clamping device 1 and the push rod device 3 can be fixed on the blending platform 2-2. The second driving mechanism 2-1 can realize the uniform mixing effect of the liquid in the reaction tube by adopting a mode that the first motor 2-1-1 drives a transmission mechanism, wherein the first motor 2-1-1 is arranged above the uniform mixing platform 2-2, and the transmission mechanism can adopt the following structure.
