Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0028] In the description of the embodiments of the utility model, it needs to be explained that, unless there is definite stipulation and limitation, the term "first" "second" is for the numbering of the components of the product for clear explanation, and it does not represent any substantial difference. The term "mounting" "connecting" "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be direct connection, or indirect connection through intermediate medium, or the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above-mentioned term in the embodiments of the utility model can be understood according to the specific circumstances. In addition, the meaning of "multiple" is two or more than two.

[0029] As Figure 1 Indicated, the utility model discloses a sample delivery device including mounting frame 1, transmission mechanism 2, first driving piece 3, to place detector 4 and controller (not shown in the drawing). Mounting frame 1 is along the vertical direction and is distributed with multiple outlets. Transmission mechanism 2 has translational transmission part, and the upper end surface of translational transmission part forms sample placement area 20, and sample placement area 20 is used to place the sample to be conveyed. The translational transmission part is used to move the sample to be conveyed along the depth direction of the outlet. First driving piece 3 is fixed to mounting frame 1 and is in transmission connection with transmission mechanism 2, and is used to drive transmission mechanism 2 to lift between multiple outlets. First driving piece 3 and to place detector 4 are respectively in communication connection with the controller. The controller is used to determine that the sample to be conveyed reaches the middle region of translational transmission part according to the detection signal of to place detector 4, and controls first driving piece 3 to start.

[0030] It can be understood that mounting frame 1 is installed between the laboratories of upper and lower floors, and the lifting space is formed in mounting frame 1. The number of outlets of mounting frame 1 is same with the number of floors needing sample transmission, and each outlet corresponds to the laboratory of a floor. Transmission mechanism 2 is located in the lifting space, and under the action of first driving piece 3, transmission mechanism 2 moves up and down between multiple outlets, thereby conveying samples between multiple laboratories of upper and lower floors.

[0031] Among them, first driving piece 3 can be lifting motor, also can be hydraulic or pneumatic driving piece. First driving piece 3 can be connected with transmission mechanism 2 through rope cable. The inner side of mounting frame 1 is provided with guide groove along the vertical direction, and transmission mechanism 2 is slidably arranged in the guide groove. The lifting of mounting frame 1 provides guidance for transmission mechanism 2, and improves the stability of the lifting movement of transmission mechanism 2.

[0032] The in-place detector 4 can be installed on the transmission mechanism 2 and correspond to the middle area of the sample placement area 20. For example, the in-place detector 4 is located on one side of the transmission direction of the translation transmission part. When the in-place detector 4 detects that the sample has reached the middle area of the sample placement area 20, a detection signal is sent to the controller, and the controller controls the first driving member 3 to start to drive the transmission mechanism 2 to start lifting. Optionally, the in-place detector is an optical sensor or an ultrasonic sensor, which can trigger a detection signal by sensing the presence of an object.

[0033] The sample delivery device can be used with a robot in a laboratory. The robot moves the tray containing the sample to the sample placement area 20 of the transmission mechanism 2. Because the robot has a limited range of motion, it can only place the tray in the edge area near the entrance of the sample placement area 20. The embodiment moves the sample to the middle area of the sample placement area 20 by the translation transmission part of the transmission mechanism 2 to ensure the safety of the sample. The middle area of the sample placement area 20 can be the center of the sample placement area 20, or an area more than 20 cm away from the edge in the moving direction.

[0034] The sample delivery device provided by the embodiment of the utility model, through setting installation frame 1, transmission mechanism 2, first driving member 3, in-place detector 4 and controller, utilize first driving member 3 drive transmission mechanism 2 in installation frame 1 along vertical direction lifting movement. The upper end surface of the translation transmission part of the transmission mechanism 2 forms the sample placement area 20, and the sample located at the edge of the sample placement area 20 can be moved to the middle area by the transmission mechanism 2. The controller determines that the sample reaches the middle area of the sample placement area 20 according to the detection signal of the in-place detector 4, and then controls the first driving member 3 to start to drive the transmission mechanism 2 to start lifting, to ensure the safe delivery of the sample. The sample delivery device realizes the automation of sample transmission between floors, reduces the sample waiting time, improves the detection work efficiency, and ensures the safety of sample transmission.

[0035] In the embodiment, the transmission mechanism 2 includes a mounting seat 21, a second driving member 22 and a transmission assembly. The first driving member 3 is in transmission connection with the mounting seat 21, and the second driving member 22 and the transmission assembly are respectively installed on the mounting seat 21. The second driving member 22 is in transmission connection with the transmission assembly, and the transmission assembly forms the translation transmission part. The in-place detector 4 can be arranged on the mounting seat 21.

[0036] In some embodiments, the transmission assembly is a roller transmission mechanism, including a plurality of transmission rollers 23 rotatably mounted on the mounting base 21, and the plurality of transmission rollers 23 are sequentially and spacedly arranged along the transmission direction of the translation transmission part. The sample placement area 20 is formed on the upper surface of the plurality of transmission rollers 23. The second driving member 22 includes a motor and a chain, the driving end of the motor and the transmission rollers are drivingly connected through the chain, and the motor drives the plurality of transmission rollers to rotate through the chain, so as to move the sample to be conveyed located thereon.

[0037] Further, the outer surface of the transmission roller 23 is covered with a shock-absorbing and anti-skid layer, which can avoid the rigid collision between the sample and the transmission roller 23, and increase the friction between the transmission roller 23 and the sample tray. For example, the shock-absorbing and anti-skid layer is a flexible material layer such as a rubber layer.

[0038] In other embodiments, the transmission assembly is a belt transmission mechanism, and the pulley of the belt transmission mechanism is rotatably mounted on the mounting base 21. The conveyor belt is in a horizontal conveying state, and the sample placement area 20 is formed on the upper surface of the conveyor belt. The second driving member 22 is a motor, and the motor drives the pulley to rotate to drive the conveyor belt to move, so as to move the sample to be conveyed located thereon.

[0039] It should be noted that the transmission mechanism 2 in the present embodiment can also be a manual transmission mechanism. For example, the transmission mechanism 2 includes a mounting base 21 and a sliding plate, and the sliding plate is slidingly mounted on the mounting base 21 in the horizontal direction. After the sliding plate is partially drawn out of the mounting base 21, the sample is placed on the transmission mechanism 2, and then the sliding plate is pushed into the mounting base 21.

[0040] The sample conveying device provided by the utility model further includes a pressure sensor 5 installed on the transmission assembly. The second driving member 22 and the pressure sensor 5 are respectively in communication connection with the controller. The controller is further used for controlling the second driving member 22 to start according to the detection signal of the pressure sensor 5 after determining that the sample to be conveyed is located in the sample placement area 20.

[0041] Among them, one or more pressure sensors 5 can be arranged in the edge area close to the entrance of the sample placement area 20. When the sample is placed in the edge area of the sample placement area 20, the pressure sensor 5 senses the pressure change and sends the detection signal to the controller. The controller controls the second driving member 22 to start according to the detection signal, so that the transmission assembly moves the sample to the middle area of the sample placement area 20.

[0042] In the case of the transmission assembly being a roller transmission mechanism, the pressure sensor 5 is installed on the transmission roller 23, for example, one to three pressure sensors 5 are arranged on the transmission rollers 23 close to the edge. After the transmission of the sample is completed, the second driving member 22 can be controlled to rotate the transmission roller 23 to a position where the pressure sensor 5 faces upward, so as to prepare for the next detection.

[0043] When it is necessary to take the sample from the sample placement area 20, the controller controls the second driving member 22 to drive the transmission assembly to move the sample to the edge area of the sample placement area 20. According to the detection signal of the pressure sensor 5, the controller determines that the sample tray reaches the edge area of the sample placement area 20, and then controls the second driving member 22 to be closed to prevent the sample from falling off the sample placement area 20.

[0044] The utility model also can not set up pressure sensor 5 on transmission assembly, but through in place detector 4 detection sample to be conveyed in the position on sample placement area. Specifically, the number of in place detector 4 is multiple, and multiple in place detectors 4 are sequentially and spaced apart along the transmission direction of the translation transmission part. The second driving member 22 is in communication connection with the controller. The controller is further used to control the second driving member 22 to start according to the detection signal of multiple in place detectors 4 when determining that the sample to be conveyed is located behind the sample placement area 20. That is, when any in place detector 4 detects signal change, it can be determined that the sample to be conveyed is located in the sample placement area 20. Optionally, the mounting seat 21 is provided with one in place detector 4 corresponding to the edge area and the middle area of the sample placement area 20 respectively.

[0045] As shown in Figure 2 The utility model discloses some embodiments, transmission mechanism 2 has multiple translation transmission parts, and both sides of each translation transmission part are provided with isolation baffle 24, and transmission channel is formed between every two adjacent isolation baffles 24.

[0046] It can be understood that multiple isolation baffles 24 form at least two transmission channels, and each transmission channel corresponds to a sample placement area 20, and a group of second driving members 22 and transmission assemblies can be correspondingly provided. In this way, each transmission channel can be used to move the sample individually, and the sample conveying device can convey more samples through single lifting transmission. The both sides of each translation transmission part are provided with isolation baffles 24, which can prevent the samples on multiple translation transmission parts from being in series, thereby affecting the stability of sample movement.

[0047] Correspondingly, each transmission channel can be provided with a pressure sensor 5, which is used to individually detect whether there is a sample on the sample placement area 20 of the transmission channel. When it is determined that there is a sample on the sample placement area 20, the controller controls the second driving member 22 to start. Each transmission channel is provided with an in place detector 4, which is used to individually detect the position of the sample in the transmission channel. When it is determined that the samples to be conveyed placed on multiple transmission channels are all located in the middle area of the corresponding sample placement area 20, the controller controls the first driving member 3 to start.

[0048] It should be noted that, in the case that the transmission mechanism 2 has only one moving transmission part, isolation baffles 24 can also be arranged on both sides of the moving transmission part to prevent the sample to be conveyed from falling off the sample placement area 20 after deviating from the path.

[0049] In some optional embodiments, the sample conveying device further comprises a sample transfer table (not shown in the figure). The sample transfer table is located outside the mounting frame 1 and is arranged opposite to the outlet, and the table top of the sample transfer table is flush with the sample placement area 20. The sample transfer table is in communication connection with the controller, and the controller is further used for controlling the sample transfer table to move close to or away from the sample placement area 20.

[0050] When it is needed to convey the sample, the sample transfer table is controlled to move close to the sample placement area 20, the sample transfer table is moved close to the sample placement area 20, the sample to be conveyed is placed on the sample transfer table by the robot, and the sample tray is at least partially located on the translation transmission part, under the driving of the translation transmission part, the sample tray moves to the middle part of the sample placement area 20. After it is determined that the sample to be conveyed reaches the middle area of the sample placement area 20, the sample transfer table is controlled to move away from the sample placement area 20. After it is determined that the sample transfer table moves away from the sample placement area 20 to a safe distance, the first driving member 3 is controlled to start.

[0051] Specifically, the sample transfer table comprises a base, a third driving member and a moving platform, the third driving member and the moving platform are respectively installed on the base, the third driving member is in transmission connection with the moving platform, and is used for driving the moving platform to move horizontally relative to the base along the transmission direction of the translation transmission part. The third driving member can be a linear cylinder or a hydraulic cylinder or the like linear driving member. A plurality of balls can be embedded on the moving platform, so as to reduce the friction force between the sample tray and the moving platform.

[0052] The utility model embodiment further provides a sample conveying system, include: robot, experiment table and above any one kind of sample conveying device. Experiment table is equipped with to be conveyed sample placement area and to be received sample placement area. Conveying sample placement area is used for placing sample tray, and sample tray is used for containing to be conveyed sample. The robot is used for picking up the sample tray and transferring the sample tray between the experiment table and the sample placement area 20.

[0053] Specifically, the sample conveying system comprises a plurality of robots and a plurality of experimental benches. The robots and the experimental benches are arranged in multiple floors. Each robot is configured to pick up a sample tray containing a sample to be conveyed from a sample placement area of a corresponding experimental bench, and transfer the sample tray to a sample placement area 20 of a corresponding sample conveying device; and also configured to pick up the sample tray from the sample placement area 20 of the sample conveying device, and transfer the sample tray to a sample placement area of the experimental bench for a laboratory technician to take. When the sample tray needs to be picked up from the sample placement area 20, the sample tray can be moved to an edge area of the sample placement area 20 by the conveying mechanism 2 for the robot to pick up. When the sample tray is detected to reach the edge area of the sample placement area 20, the second driving member 22 is controlled to be closed. Through the cooperation of the robot and the sample conveying device, the automation of sample conveying between floors is improved, the manpower is saved, and the work efficiency is improved.

[0054] Optionally, the robot can be an AGV (Automated Guided Vehicle) robot capable of traveling along a specified navigation path.
