[0037] A first placement tray 200 is disposed on the frame 100 for placing blood collection tubes 600. Specifically, it can hold multiple blood collection tubes 600, which can be arranged side by side and extend vertically. A second placement tray 300 is disposed on the frame 100 for placing tube caps 700. Specifically, it can hold multiple tube caps 700, which can be arranged side by side and extend vertically.

[0038] The material handling assembly 400 includes a material handling plate 401 and a material handling component 402. The material handling plate 401 is movably disposed on the frame 100, for example, it can move horizontally and lift. The material handling component 402 is disposed on the bottom surface of the material handling plate 401. The material handling plate 401 is provided with a first gas supply pipe 403, which is used to connect to a vacuum device. The material handling plate 401 can be moved to a first position and a second position. When the material handling plate 401 is in the first position, the material handling component 402 picks up the tube cap 700 on the second placement tray 300. When the material handling plate 401 is in the second position, the material handling component 402 places the tube cap 700 on the blood collection tube 600 of the first placement tray 200, and the material handling plate 401 covers the top of the first placement tray 200 to form a sealed cavity communicating with the first gas supply pipe 403.

[0039] In this application, a blood collection tube 600 is placed on a first placement tray 200, and a tube cap 700 is placed on a second placement tray 300. The material-retrieving plate 401 is moved to a first position, allowing the material-retrieving component 402 on the plate 401 to extract the tube cap 700 from the second placement tray 300. Then, the material-retrieving plate 401 is moved to a second position, allowing the material-retrieving component 402 to place the tube cap 700 onto the blood collection tube 600 on the first placement tray 200, thus completing the capping of the blood collection tube 600. Simultaneously, the material-retrieving plate 401 seals the top of the first placement tray 200, forming a sealed cavity. A vacuuming device evacuates the sealed cavity through a first gas supply pipe 403, indirectly evacuating the blood collection tube 600.

[0041] In this embodiment, the sliding part 500 slides along the second horizontal direction to the top of the second placement tray 300, and then the picking plate 401 is lowered, which makes it easy for the picking member 402 to pick up the tube cap 700 on the second placement tray 300. Then the sliding part 500 slides along the second horizontal direction to the top of the sliding path of the first placement tray 200, and slides the first placement tray 200 to the bottom of the sliding part 500. Then the picking plate 401 is lowered, which allows the picking member 402 to place the tube cap 700 on the blood collection tube 600 of the first placement tray 200. The picking plate 401 covers the top of the first placement tray 200 to form a sealed cavity that connects to the first gas delivery tube 403. The operation is simple and convenient.

[0042] refer to Figure 1 As shown, in some embodiments of this utility model, the frame 100 is provided with a lead screw 107 and a first motor 108. The lead screw 107 is rotatably mounted on the frame 100 and extends along the first horizontal direction. The first motor 108 is drivenly connected to the lead screw 107. The lead screw 107 is threadedly connected to the first placement plate 200.

[0043] When the first motor 108 is started, it drives the lead screw 107 to rotate. The lead screw 107 is connected to the first placement disk 200 by a thread, which drives the first placement disk 200 to slide. The structure is simple, the operation is convenient, and the driving accuracy is high.

[0044] It should be noted that the first placement plate 200 can also be slid directly by driving the hydraulic cylinder.

[0045] refer to Figures 1 to 4 As shown, in some embodiments of this utility model, the frame 100 is provided with two racks 109, which extend along the second horizontal direction. The sliding part 500 is provided with two gears 501 and a second motor 502. The two gears 501 respectively mesh with the two racks 109, and the second motor 502 is drivenly connected to one of the gears 501.

[0046] When the second motor 502 is started, it drives the gear 501 to rotate. The gear 501, through meshing with the rack 109, drives the sliding part 500 to slide. The structure is simple, the operation is convenient, and the driving precision is high.

[0047] It should be noted that the second placement plate 300 can also be driven to slide directly by a hydraulic cylinder.

[0048] refer to Figures 1 to 4 As shown, in some embodiments of this utility model, the sliding part 500 is provided with a lifting cylinder 503, which is connected to the top of the material picking plate 401.

[0049] In this embodiment, the lifting plate 401 can be directly lifted and lowered by extending and retracting the lifting cylinder 503. The structure is simple, the operation is convenient, and the driving precision is high.

[0050] refer to Figures 1 to 4 As shown, in some embodiments of the present invention, the first placement tray 200 forms a receiving cavity 201 with an open top. The top of the side wall of the receiving cavity 201 is provided with an annular sealing groove 202. The edge of the bottom end of the material taking plate 401 is provided with an annular sealing wall 404. When the material taking plate 401 is in the second position, the annular sealing wall 404 is inserted into the annular sealing groove 202.

[0051] In this embodiment, when the material taking plate 401 is in the second position, the annular sealing wall 404 is inserted into the annular sealing groove 202, thereby making the sealing effect of the formed sealing cavity better, and thus making the vacuuming effect of the blood collection tube 600 better.

[0052] refer to Figure 3 As shown, in some embodiments of this utility model, when the material taking component 402 drives the tube cap 700 to a preset position above the blood collection tube 600, the annular sealing wall 404 is inserted into the annular sealing groove 202.

[0053] That is, even before the cap 700 is placed on the blood collection tube 600, the annular sealing wall 404 is already inserted into the annular sealing groove 202, thus improving the vacuuming effect on the blood collection tube 600.

[0054] refer to Figures 1 to 4 As shown, in some embodiments of this utility model, the top of the cap 700 is provided with a rubber stopper hole. The material-retrieving component 402 includes a material-retrieving rod 405 and a material-retrieving head 406. The material-retrieving rod 405 is vertically disposed at the bottom end of the material-retrieving plate 401, and the material-retrieving head 406 is disposed at the bottom end of the material-retrieving rod 405. The material-retrieving head 406 is configured to be inserted into the rubber stopper hole for extracting the cap 700. For example, the wall of the rubber stopper hole can elastically expand and contract. In its natural state, the size of the material-retrieving head 406 is larger than the diameter of the rubber stopper hole. When the material-retrieving head 406 is inserted into the rubber stopper hole, the rubber stopper hole expands, clamping the material-retrieving head 406, thereby extracting the cap 700. Extraction is simple and convenient.

[0055] refer to Figures 1 to 4 As shown, in some embodiments of this utility model, the material handling assembly 400 further includes a telescopic member 407 and a limiting plate 408. The telescopic member 407 is located at the bottom end of the material handling plate 401 and can extend and retract vertically. The limiting plate 408 is horizontally located at the bottom end of the telescopic member 407 and has a through hole for the material handling rod 405 and the material handling head 406 to pass through. The diameter of the through hole is smaller than the outer diameter of the cap 700. For example, the telescopic member 407 can be a hydraulic cylinder or a pneumatic cylinder.

[0056] After the picking member 402 places the tube cap 700 on the blood collection tube 600, the telescopic member 407 extends, so that the limiting plate 408 abuts against the top of the tube cap 700. When the picking plate 401 rises and drives the picking member 402 to rise, the telescopic member 407 continues to extend, so that the limiting plate 408 always abuts against the top of the tube cap 700, thus preventing the tube cap 700 from rising with the picking member 402, thereby facilitating the separation of the tube cap 700 from the picking member 402.

[0057] refer to Figures 1 to 4 As shown, in some embodiments of this utility model, a rubber plate 203 is provided inside the receiving cavity 201, and the rubber plate 203 has a plurality of receiving holes 204 for receiving blood collection tubes 600. In this embodiment, this arrangement not only allows for the placement of more blood collection tubes 600, but also reduces the damage to the blood collection tubes 600 when the tube cap 700 is installed.

[0058] refer to Figure 5 As shown, in some embodiments of this utility model, the frame 100 has a placement surface 101, the placement surface 101 is provided with a limiting part 102, the bottom surface of the second placement tray 300 is provided with a limiting groove 301, the second placement tray 300 is placed on the placement surface 101, the limiting part 102 is located in the limiting groove 301, and the side wall of the limiting part 102 is attached to the side wall of the limiting groove 301. In this embodiment, the second placement tray 300 is placed on the placement surface 101, which is convenient for picking up and putting down. The limiting part 102 is located in the limiting groove 301, and the side wall of the limiting part 102 is attached to the side wall of the limiting groove 301, which can accurately position the second placement tray 300, thereby facilitating the picking part 402 to pick up the tube cap 700.

[0059] refer to Figure 5 As shown, in some embodiments of this utility model, the top surface of the limiting groove 301 is attached to the top surface of the limiting part 102. The frame 100 is provided with a negative pressure chamber 103, and the top surface of the limiting part 102 is provided with a negative pressure hole 104 communicating with the negative pressure chamber 103. The frame 100 is provided with a second air supply pipe 105 communicating with the negative pressure chamber 103. The second air supply pipe 105 is used to connect to a vacuum device. When the material take-up piece 402 extracts the cap 700, the vacuum device extracts the air in the negative pressure chamber 103 through the second air supply pipe 105, so that a negative pressure environment is formed in the negative pressure chamber 103, which can adsorb the second placement tray 300 and prevent the second placement tray 300 from being moved when the cap 700 is extracted.

When it is necessary to remove the second placement tray 300, the second air valve 106 is opened to connect the negative pressure cavity 103 with the external environment, thereby relieving the negative pressure environment of the negative pressure cavity 103 and facilitating the removal of the second placement tray 300.

[0062] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings.
