[0002] A vacuum blood collection tube is a disposable negative pressure vacuum glass tube that can achieve quantitative blood collection. The structure of a traditional vacuum blood collection tube includes: a test tube and a test tube cap connected to the mouth of the test tube. The connection method of the test tube cap is usually spiral or plug type. For the traditional automatic assembly of vacuum blood collection tubes, the test tube caps are usually conveyed by a vibrating disk, and then the conveyed test tube caps are clamped by a manipulator to the mouth of the test tube, and finally completely assembled through a rotating mechanism or a pressing mechanism. The disadvantages are: the conveyance of the test tube caps is relatively difficult, such as easy occurrence of jamming or wrong direction problems, which will lead to the failure of assembly and the decline of efficiency.

[0018] Refer to Figures 1-5As shown in the figure, the automatic assembly machine for vacuum blood collection tubes of the present utility model includes a workbench 1 and an XY-axis rail slider 2 provided on the workbench 1. A first pneumatic gripper 3 is provided on the XY-axis rail slider 2. The XY-axis rail slider 2 can drive the first pneumatic gripper 3 to move left and right and up and down to complete the clamping of the test tube cap and place it on the test tube mouth. A pressure rod 4 is further provided in the middle of the first pneumatic gripper 3, and the pressure rod 4 is also driven to expand and contract by the cylinder of the first pneumatic gripper 3. A ejector rod 5 and a driving mechanism for driving the ejector rod 5 to expand and contract are provided in the workbench 1 corresponding to the lower part of the first pneumatic gripper 3, and the driving mechanism controls the ejection distance of the ejector rod 5. A second pneumatic gripper 6 is provided on one side of the workbench 1 corresponding to the ejector rod 5. The second pneumatic gripper 6 is used to clamp the test tube 21. The first pneumatic gripper 3 and the second pneumatic gripper 6 are usually located on the same horizontal plane, so that the test tube cap on the first pneumatic gripper 3 can be accurately placed into the test tube 21, and then the test tube cap is pressed into the test tube 21 by the pressure rod 4. The test tube cap needs to be of a plug structure. During operation, the test tube cap in the tooling is ejected by the ejector rod 5, then clamped by the first pneumatic gripper 3 to the test tube mouth, and finally the test tube cap is pressed into the test tube 21 directly by the pressure rod 4 at the center of the first pneumatic gripper 3. Note: The cylinder with both clamping and telescopic functions is a well-known technology and will not be elaborated here.

[0019] Preferably, the driving mechanism includes a rail 7, a slider 8 provided on the rail 7, and a lead screw 9 provided on the slider 8. The lower end of the lead screw 9 is connected to a stepping motor 10, and the ejector rod 5 is connected to the slider 8. The rotation of the stepping motor 10 can accurately drive the ejection distance of the ejector rod 5.

[0020] Preferably, a divider 11 is provided above the driving mechanism, and a first mounting port 12 is provided at the center of the divider 11. A turntable 13 is provided on the workbench 1, and a second mounting port 14 corresponding to the first mounting port 12 is provided at the center of the turntable 13. A cylindrical tooling 15 is provided between the first mounting port 12 and the second mounting port 14. The side wall of the cylindrical tooling 15 is provided with test tube cap receiving grooves 16 arranged in a circumferential array and axially penetrating, and a positioning boss 17 is provided at the bottom of the test tube cap receiving grooves 16. The divider 11 rotates the cylindrical tooling 15 in equal parts. During assembly, several test tube caps 22 are overlapped and placed into the test tube cap receiving grooves 16 of the cylindrical tooling 15, and then they are ejected one by one by the ejector rod 5. When the test tube caps in a row of the test tube cap receiving grooves 16 are all ejected, the ejector rod 5 retracts, and then through the equal-part rotation of the divider 11, the next row of the test tube cap receiving grooves 16 is switched to the position of the ejector rod 5, so that the ejector rod 5 can continue to work. Thus, the working efficiency is greatly improved.

[0021] Preferably, the test tube cap receiving groove 16 is provided with an axially extending slot 18 to facilitate the user to observe the state of the test tube cap in the test tube cap receiving groove 16.
