Description

Technical Field

[0001] The utility model belongs to the technical field of sampling tube production, in particular to a tube loading and suction device. Background Art

[0002] A glass sampling tube or sampling tube is a common device for packaging and preserving samples. It is usually made of different materials according to different actual uses. During the production process of sampling tubes and pipe fittings in the form of similar sampling tubes, some processes have specific requirements on the placement and quantity of the sampling tubes. For example, the tube bodies of all sampling tubes face the same side, and the tube caps of all sampling tubes face the other side.

[0003] Therefore, before subsequent processing or assembly, the sampling tube needs to be mounted on a rack, that is, the sampling tube needs to be placed on a rack. During the mounting operation, the traditional tube clamping device is prone to unstable assembly and the sampling tube may fall over. Utility Model Content

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0016] (1) The utility model provides a pipette-loading device. When the pipette is working, the displacement cylinder pushes the mounting seat to slide along the guide rod to the upper side of the sampling tube. Then the pipette cylinder works to push the adsorption seat toward the sampling tube until the suction nozzle presses against the sampling tube. The adsorption seat is hollow and connected to an external vacuum device to perform vacuum so that the sampling tube is adsorbed on the suction nozzle. The central axis of the pipette cylinder forms an angle of 80° with the central axis of the displacement cylinder, so that the sampling tube can be adsorbed more conveniently and stably and is easy to move.

[0017] (2) The utility model provides a tube loading and suction device. The displacement cylinder is retracted to drive the mounting seat to move above the tube loading assembly. Then the vacuum device stops working and the suction nozzle no longer absorbs the sampling tube. The sampling tube directly falls into the tube bin and slides along the guide surface. Therefore, the tube loading operation can be carried out by placing a tube rack under the tube loading assembly. For sampling tubes of different lengths or different tube racks, a tube fixing cylinder is provided for cooperation. The tube fixing cylinder pushes out the tube fixing plate to limit the sampling tube and prevent it from tipping over, so that the sampling tube can be stably and orderly loaded into the tube rack.
