The left support column 313 and the right support column 314 are both located between the upper mounting plate 311 and the lower mounting plate 312 and are respectively connected to the upper mounting plate 311 and the lower mounting plate 312. The lower end of the guide rail 12 is connected to the upper mounting plate 311. The fixing plate 32 is horizontally... The mounting plate 311 is horizontally positioned and located between the upper mounting plate 311 and the lower mounting plate 312.

[0043] With the above configuration, when the guide rail 12 needs to be raised or lowered by the lifting device 13, the synchronous pulley 132 is driven to rotate around the left and right direction by the driving component 133. Since the synchronous pulley 132 is located in front of the synchronous belt 131 and meshes with the synchronous belt 131, similar to a gear and rack combination, the guide rail 12 can be moved vertically by the synchronous belt 131.

[0044] The driving component 133 can be any suitable driving component. In a specific embodiment of this utility model, the driving component 133 is a motor.

Figure 4As shown, in a specific embodiment of this utility model, the eight-port pipe cover loading mechanism 2 further includes a left detection device 22 and a right detection device 23. The left detection device 22 and the right detection device 23 are both arranged downwards and spaced apart from each other, and are both used to detect whether the eight-port pipe cover 5 exists below them. The left detection device 22 and the right detection device 23 are both located below the lower mounting plate 312 and are both connected to the lower mounting plate 312. The positioning pin 21 is located between the left detection device 22 and the right detection device 23.

[0052] The left detection device 22 and the right detection device 23 can be any suitable detection device. In a specific embodiment of this utility model, the left detection device 22 and the right detection device 23 are both photodetectors.

[0053] Preparations before use: Please refer to Figure 6 As shown, the eight-unit pipe support frame 7 is set horizontally and along the front-to-back direction. The eight-unit pipe bodies 4 are inserted into the eight-unit pipe support frame 7 along the left-to-right direction. Multiple rows, such as six rows of eight-unit pipe bodies 4, are arranged alternately front to back. The eight-unit pipe covers 5 are inserted into the eight-unit pipe support frame 7 along the left-to-right direction. Multiple rows, such as six rows of eight-unit pipe covers 5, are arranged alternately front to back. Here, three rows of eight-unit pipe covers 5 and three rows of eight-unit pipe bodies 4 are arranged alternately front to back. Now, the eight-unit pipe covers 5 need to be placed on the eight-unit pipe bodies 4 and the entire assembly needs to be moved.

[0054] In use, the fixing base 11 of this utility model is fixed, for example, to the moving mechanism of a biomedical research automated workstation. This utility model is then moved above one row of eight-unit pipe covers 5, so that the positioning pin 21 aligns with the pre-drilled hole 6 of that row of eight-unit pipe covers 5. Then, the guide rail 12 is lowered via the lifting device 13, causing the mechanism frame 31 to descend, which in turn causes the positioning pin 21 to descend, pressing it into the pre-drilled hole 6 of that row of eight-unit pipe covers 5. Then, the guide rail 12 is raised via the lifting device 13, causing the mechanism frame 31 to rise, which in turn causes the positioning pin 21 to rise, lifting one row of eight-unit pipe covers 5. Figures 1-3As shown; the present invention is moved above one of the rows of eight-unit pipe bodies 4, so that the cap 5 of one row of eight-unit pipe bodies 4 is aligned with the opening of the pipe body 4. Then, the guide rail 12 is lowered by the lifting device 13, which drives the mechanism frame 31 and the positioning pin 21 to descend, thereby driving the cap 5 of one row of eight-unit pipe bodies 4 to descend, so that the cap 5 of one row of eight-unit pipe bodies 4 is pressed into the opening of the pipe body 4, completing the capping operation. Then, the guide rail 12 is raised by the lifting device 13, which drives the mechanism frame 31 and the positioning pin 21 to rise, thereby lifting the cap 5 of one row of eight-unit pipe bodies 4. The first row of eight-pipe covers 5 lifts up one row of eight-pipe bodies 4, thus lifting the eight-pipe system. The system is then moved above the desired transfer position. The lifting device 13 lowers the guide rail 12, causing the mechanism frame 31 and positioning pin 21 to descend, thereby lowering the eight-pipe system. The vertical movement drive device 34 lowers the fixing plate 32, causing the pipe-removing pin 33 to move downwards, pushing the first row of eight-pipe covers 5 downwards, freeing it from the restriction of the positioning pin 21, completing the unloading of the eight-pipe system, and finally completing the transfer operation of the eight-pipe system.

[0055] If there are detection optocouplers 36 and detection baffles 37, during the process of moving the fixed plate 32 downward by the vertical moving drive device 34, the detection baffles 37 move downward and eventually disengage from the detection optocouplers 36, and can no longer be detected by the detection optocouplers 36. This can limit the downward movement position of the tube retraction pin 33. At this time, the vertical moving drive device 34 can be automatically controlled by the signal to stop working.

[0056] If there are left detection device 22 and right detection device 23, when the positioning pin 21 is pressed into the pre-made hole 6 of one of the rows of eight-unit pipe covers 5, the one of the rows of eight-unit pipe covers 5 is below the left detection device 22 and right detection device 23 and is detected by the left detection device 22 and right detection device 23, thus realizing the detection of the one of the rows of eight-unit pipe covers 5.

[0057] Therefore, this utility model provides a device for capping and transferring eight-tube arrays, which can be adapted to eight-tube arrays used in biochemical testing, and realizes the capping and transfer of eight-tube arrays. It has an ingenious design, a compact and simple structure, is easy to manufacture, has low cost, occupies little space, is easy to install, and is suitable for large-scale promotion and application.

It has an ingenious design, simple structure, is easy to manufacture, and has low manufacturing cost, making it suitable for large-scale promotion and application.
