Specifically, the number of the first sensor 3 is two, which are respectively mounted on the left and right sides of the rack 1, and each first sensor 3 is a photoelectric switch and faces the pre-check station.

[0034] The baffle 4 is vertically arranged and is movably mounted on the guide seat 11. Specifically, the bottom of the baffle 4 has two guide rods 41 corresponding to the guide holes 111, each guide rod 41 is movably arranged in the corresponding guide hole 111, and the bottom ends of the guide rods 41 are connected by a connecting rod 411.

[0035] The first driving member 5 is used to drive the baffle 4 to move up and down. Specifically, the first driving member 5 is a pneumatic cylinder and is mounted on the bottom of the guide seat 11, and the power output end of the first driving member 5 is connected with the connecting rod 411.

[0036] The baffle 4 and the first driving member 5 form a limiting assembly, which is used to limit the fume hood 10 moving to the detection station in the detection station.

[0037] The first driving member 5 is started to drive the baffle 4 to move up and down through the connecting rod 411, so that the baffle 4 has at least the following two states:

[0038] In the first state, the baffle 4 is lifted to the limit state and blocks the fume hood 10 moving to the detection station in the front direction, so that the fume hood 10 is kept in the detection station.

When the hoods 10 move forward to the pre-detection station, the first sensor 3 senses the hoods 10 and sends signals to the controller, and the controller controls the first driving member 5 to drive the baffle 4 to rise. When the hoods 10 continue to move forward to the detection station, the baffle 4 is blocked in front of the hoods 10, so that the hoods 10 are kept at the detection station. At this time, the second sensor 6 senses the hoods 10 and sends signals to the controller, and the controller controls the second driving member 8 to drive the corresponding third sensor 7 to approach the hoods 10.
