The tray 200 is installed on the main plate 100, and the tray 200 defines a first placement groove 210 and a second placement groove 220. The bottom of the first placement groove 210 is provided with a first opening 211, and the size of the first opening 211 is smaller than the size of the bottom of the first placement groove 210, so that the bottom of the first placement groove 210 has a first placement surface 212, and the first placement surface 212 is used to place a first freezing box. The bottom of the second placement groove 220 is provided with a second opening 221, and the size of the second opening 221 is smaller than the size of the bottom of the second placement groove 220, so that the bottom of the second placement groove 220 has a second placement surface 222, and the second placement surface 222 is used to place a second freezing box. The first freezing box and the second freezing box are both used to place freezing tubes. The first freezing box and the second freezing box are placed on the tray 200 so that the transfer mechanism can realize the transfer of the freezing tubes between the first freezing box and the second freezing box.

When the box moving plate 300 is in the box taking state, the box moving plate 300 receives the first freezing box or the second freezing box from the storage device, and drives the first freezing box or the second freezing box to move above the first opening 211 or the second opening 221, and then places the first freezing box or the second freezing box on the first placement surface 212 or the second placement surface 222 through the relative vertical movement. When the box moving plate 300 is in the box storing state, the box moving plate 300 moves to below the first opening 211 or the second opening 221, and then lifts the first freezing box or the second freezing box through the relative vertical movement, and drives the first freezing box or the second freezing box to move to the storage device.

Alternatively, the user puts the first cryopreservation box and the second cryopreservation box into the tray 200 through the shell opening, the tube transfer mechanism transfers the A and B cryopreservation tubes in the first cryopreservation box to the second cryopreservation box, and then the box transfer plate 300 returns the second cryopreservation box to the storage cavity.
