[0014] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiment is one embodiment of the present invention, not all embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0016] This embodiment provides a test tube capping device.

[0017] refer to Figure 1 , Figure 2 A test tube capping device includes a tube cap clamping and lifting assembly 1 and a tube body clamping and rotating assembly 2. The tube cap clamping and lifting assembly 1 can clamp and fix the tube cap and drive it to lift vertically, and includes a clamping jaw 11 and a clamping cylinder 12. The clamping jaw 11 is used to clamp and fix the tube cap, and the clamping cylinder 12 is used to carry the clamping jaw 11 and drive it to lift vertically.

[0018] The tube body clamping and rotating assembly 2 is relatively arranged below the tube cover clamping and lifting assembly 1, and is used to clamp the tube body and drive it to rotate, and includes a sleeve 21, a rotating body 22, an airbag 23, and a rotating drive assembly. The sleeve 21 is vertically arranged on the base plate, the rotating body 22 is vertically arranged in the sleeve 21 and is rotatably connected thereto, and the rotating drive assembly is used to drive the rotating body 22 to rotate along the sleeve 21.

[0019] The rotating body 22 is provided with a lumen for accommodating the tube body. The airbag 23 is provided in the lumen for contacting and clamping the tube body. In a specific implementation, the airbag is preferably a ring-shaped airbag. When the airbag 23 is inflated, the airbag 23 contacts the tube body. At this time, the tube body is clamped and fixed in the lumen, and the rotating body 22 can drive the tube body to rotate together. When the airbag 23 is deflated and contracted, the airbag 23 and the tube body are separated, and at this time, the tube body can be separated from the lumen.

[0020] In order to realize automatic lifting and lowering control of the tube cover during opening and closing operations and reduce the movement of the clamping cylinder 12, the tube cover clamping and lifting assembly 1 also includes a supporting block 13 arranged on the clamping cylinder 12, and the clamping claw 11 can be vertically slidably connected to the supporting block 13 by a connection method such as a telescopic rod, and a compression spring 131 is arranged at the vertical sliding connection.

[0021] The process of opening and closing the cover is as follows: when opening the cover, the clamping cylinder 12 drives the clamping claw 11 to move downward and clamp the tube cover, and at the same time inflates the air bag 23 to clamp and fix the tube body, then the rotating body 22 rotates, and the tube cover drives the clamping claw 11 to press the compression spring 131 upward under the action of the thread drive, and when the tube body and the tube cover are completely separated, the clamping cylinder 12 drives the clamping claw 11 to move upward, and the opening operation is completed; When closing the cover, the clamping cylinder 12 drives the jaws 11 to move downward again and make the tube cover and the tube body conflict with each other, then the rotating body 22 rotates in the opposite direction, and the tube cover is tightened downward under the action of the thread drive and the compression spring 131 is stretched downward. When the tube cover and the tube body are fully matched, the jaws 11 are separated from the tube cover, and the clamping cylinder 12 drives the jaws 11 to move upward again and reset, completing the closing operation.

[0022] The tube cover clamping and lifting assembly 1 also includes a yielding slide rail 14, which is arranged below the clamping cylinder 12 and is used to drive the tube cover clamping and lifting assembly 1 to slide relatively to the side of the tube body clamping and rotating assembly 2 when filling the test tube, thereby giving up the space above the tube body clamping and rotating assembly 2, so as to facilitate the filling of the test tube into the tube cavity or the addition of relevant experimental substances into the test tube after the cover is opened.

[0023] The tube body clamping and rotating assembly 2 also includes a slide rail assembly 24, which is arranged below the base plate and is used to drive the tube body clamping and rotating assembly 2 to slide to a corresponding position, and then cooperate with related structures to achieve the addition of experimental substances.

[0024] In the specific implementation of the present application, in order to further improve the efficiency of screwing the caps on the test tubes, a plurality of corresponding groups of the tube cap clamping and lifting components 1 and the tube body clamping and rotating components 2 may be provided.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
