The handling device 20 comprises two rails (a first rail 21 and a second rail 22) and a transition 23 between the two rails, which transition 23 can be fixed between the first rail 21 and the second rail 22. The test tube rack may complete the crossing from the first rail 21 to the second rail 22 through the transition portion 23. The limiting device 10 is simple in structure, and cannot interfere with the transition portion 23 when used, and stability of the carrying device 20 is improved. The track crossing stop device 10 provided in the present application will be described in detail below.
Referring to fig. 1, in particular, the limiting device 10 includes a blocking plate 11 and a driving assembly 12.
The driving assembly 12 is connected to the blocking plate 11 and is used for driving the blocking plate 11 to move in the horizontal direction. The blocking plate 11 has a first state and a second state, as shown in fig. 3 and 4, in the first state, the blocking plate 11 is located at the transition portion 23 to block the test rack from crossing the track between the two tracks; as shown in fig. 1 and 2, in the second state, the blocking plate 11 is disposed away from the transition portion 23 so that the test tube rack can straddle the transition portion 23.

When the test tube rack cross-track limiting device is used, as shown in fig. 2 and 4, the limiting device 10 is located on one side of the carrying device 20, and when the carrying device 20 needs to limit the cross-track of the test tube rack, the driving assembly 12 drives the blocking plate 11 to move horizontally to the transition portion 23 (the blocking plate 11 is in the first state) to block the cross-track of the test tube rack. When the limitation needs to be removed, the driving assembly 12 drives the blocking plate 11 to be far away from the transition part 23 (the blocking plate 11 is in the second state), so that the test tube rack can cross the rail through the transition part 23.
The stopper device 10 of the present application has a simple structure, and the stopper device 10 is separated from the transition portion 23 of the conveying device 20, and does not interfere therewith, so that the transition portion 23 can be fixed between the first rail 21 and the second rail 22, and thus, the structural stability of the conveying device 20 can be improved.

In the embodiment shown in fig. 1 and 3, the first sliding member 122 is a linear sliding block, the second sliding member 123 is a linear guiding rail, both the linear guiding rail and the linear sliding block extend along a horizontal direction, the blocking plate 11 is fixedly connected with the linear guiding rail, the driving member 124 drives the linear guiding rail to slide relative to the linear sliding block, and the blocking plate 11 moves in the horizontal direction to realize the switching between the first state and the second state.
In this embodiment, the linear guide extends in the same direction as the barrier plate 11. In the first state, the blocking plate 11 is driven by the linear guide to extend out of the fixing frame 121, so that the blocking plate 11 extends to the transition portion 23 of the carrying device 20. In the second state, the blocking plate 11 is retracted to the fixing frame 121 under the action of the linear guide rail, and is arranged side by side with the fixing frame 121. In this way, the space occupied by the stopper device 10 can be reduced.

In this embodiment, as shown in fig. 1 and 3, the position limiting device 10 further includes a first sensing member 13 and a second sensing member 14. The first sensing part 13 and the second sensing part 14 are disposed on the fixing frame 121 at intervals, and the first sensing part 13 and the second sensing part 14 are used for sensing the state of the blocking plate 11. The first sensing piece 13 is used for sensing whether the barrier plate 11 is in a first state; the second sensing member 14 is used for sensing whether the blocking plate 11 is in the second state.
