[0039] Among them, the transfer bucket transfer mechanism 2 includes a first connection bracket 201 fixedly connected to the lower end of the bearing plate 9. Two first sliding seats 204 are slidably connected to the front side of the first connection bracket 201. The front end of the first sliding seat 204 is fixedly connected with a first lifting seat 202. Inside the first lifting seat 202, there is a conveyor belt 203.

[0040] Furthermore, the numerical control module 10 is electrically connected to each mechanism in the device, used for precisely controlling the mechanisms and recording the storage data of the samples, thereby improving the efficiency and accuracy of sample management.

[0041] Furthermore, cryopreservation boxes are placed inside the transfer bucket body 3.

[0042] Furthermore, the up and down sliding of the first sliding seat 204 is driven by an externally connected electric push rod. When storing samples, the transfer bucket body 3 is placed on the upper end of the conveyor belt 203. Pushing the first sliding seat 204 upward by the electric push rod can drive the transfer bucket body 3 upward.

[0043] According to Figure 3 and Figure 4 As shown in the figure, the cryopreservation box gripping mechanism 4 includes a first guide rail 401 fixedly connected to the upper end of the bearing plate 9. The rear end of the first guide rail 401 is fixedly connected with a second guide rail 402. The lower end of the second guide rail 402 is fixedly connected with the upper end of the bearing plate 9.

The first mounting seat 4061 is used for mounting a stepping motor, and the output end of the stepping motor penetrates through the upper end of the support plate 406 and is fixedly connected to the upper end of the rotating seat 4062. The rotating seat 4062 can be driven to rotate by the stepping motor.

[0045] Further, a fourth guide rail 407 is fixedly connected to the right part of the front end of the second sliding seat 403. A third connecting bracket 408 is slidably connected to the front end of the fourth guide rail 407. A mechanical claw 409 is arranged at the front end of the third connecting bracket 408. The mechanical claw 409 is driven by a motor, and the motor controls the opening and closing action of the claw by controlling the current and voltage.

[0046] Further, the sliding of the second sliding seat 403 is pushed by an external stepping motor and a screw. When the transfer barrel body 3 moves upward, the end cover 301 at the upper end of the transfer barrel body 3 will be caught between the two elastic clamping blocks 4063. Driving the rotating seat 4062 to rotate by the stepping motor can make the two elastic clamping blocks 4063 drive the end cover 301 to rotate, so as to remove the end cover 301 from the transfer barrel body 3. Then, the second sliding seat 403 is driven to move to the left by the stepping motor and the screw, so that the mechanical claw 409 is located directly above the transfer barrel body 3. The frozen storage box inside the transfer barrel body 3 can be grabbed by the contraction of the mechanical claw 409. After the mechanical claw 409 grabs the frozen storage box, the second sliding seat 403 will reset. At this time, the frozen storage box is located directly above the label reading mechanism 5.

[0047] Refer to Figure 5 As shown, the label reading mechanism 5 includes a fixed housing 501 fixedly connected to the lower end of the carrier plate 9. A label reader 502 is arranged inside the fixed housing 501. In addition to the label reader 502 arranged inside the fixed housing 501, a photoelectric element for assisting in label reading is also arranged.

[0048] Further, after the frozen storage box is transferred to directly above the label reading mechanism 5, the label reader 502 will sequentially scan the labels on the frozen storage box and the test tube labels inside the frozen storage box and store them in the numerical control module 10 to generate corresponding storage positions.

[0049] Refer to Figure 6 As shown, the transfer mechanism 6 includes a fifth guide rail 601 fixedly connected to the upper end of the carrier plate 9. A carrier seat 602 is slidably connected to the left end of the fifth guide rail 601. A storage groove 603 is arranged inside the carrier seat 602. The front end of the carrier seat 602 is rotatably connected to a side baffle 604 through a rotating shaft. A second mounting seat 605 is arranged at the rear end of the storage groove 603.

[0050] Furthermore, the movement of the bearing seat 602 is driven by an external stepping motor and a screw rod. The storage slot 603 is used to place the cryopreservation box, the side baffle 604 is used to limit the cryopreservation box, and the second mounting seat 605 is used to mount the electric push rod and the stepping motor. By driving the rotation of the rotating shaft with the stepping motor, the side baffle 604 can be driven to rotate and open and close. The output end of the electric push rod abuts against one end of the cryopreservation box away from the side baffle 604. By pushing the cryopreservation box outward with the electric push rod, the cryopreservation box can be pushed out of the storage slot 603.

[0051] Furthermore, after the label reader 502 scans the label of the cryopreservation box, the mechanical gripper 409 will place the cryopreservation box in the storage slot 603. By the cooperation of the stepping motor and the screw rod to drive the movement of the bearing seat 602, the cryopreservation box can be transported. After the bearing seat 602 moves to the end of the fifth guide rail 601, it stops moving. At this time, the cryopreservation box is aligned with the storage opening 901.

[0052] Refer to Figure 4 As shown, the lid opening mechanism 8 includes a fourth sliding seat 801 slidably connected to the upper ends of the first guide rail 401 and the second guide rail 402. The left end of the fourth sliding seat 801 is fixedly connected to a ninth guide rail 802. The left end of the ninth guide rail 802 is slidably connected to a third lifting seat 803. The lower end of the third lifting seat 803 is fixedly connected to the upper end of the sealing cover 101.

[0053] Furthermore, the movements of the fourth sliding seat 801 and the third lifting seat 803 are both driven by an external stepping motor and a screw rod. By driving the third lifting seat 803 to slide upward with the stepping motor and the screw rod, the sealing cover 101 can be driven to move upward, thereby opening the liquid nitrogen barrel 1. Then, by driving the fourth sliding seat 801 to move to the right with the stepping motor and the screw rod, the sealing cover 101 is moved away from directly above the storage opening 901, which is convenient for the subsequent removal of the cryopreservation rack.

[0054] Refer to Figure 8 As shown, the cryopreservation rack body 11 includes a plurality of storage plates 1101 evenly distributed at equal intervals. Four connecting rods 1102 are fixedly connected between two adjacent storage plates 1101. The cryopreservation box is stored on the upper end of the storage plate 1101.

[0055] Refer to Figure 7As shown, the cryopreservation rack extraction mechanism 7 includes a fourth connecting frame 701 fixedly connected to the upper end of the bearing plate 9. The right end of the fourth connecting frame 701 is fixedly connected with a sixth guide rail 702. A third sliding seat 703 is slidably connected to the right end of the sixth guide rail 702. The right end of the third sliding seat 703 is fixedly connected with a seventh guide rail 704. A second lifting seat 705 is slidably connected to the right end of the seventh guide rail 704. The lower end of the second lifting seat 705 is fixedly connected with a cryopreservation rack lifting rod 706. The lower end of the fourth connecting frame 701 is fixedly connected with an eighth guide rail 707. A push plate 708 is slidably connected to the upper end of the eighth guide rail 707.

[0056] Furthermore, the movements of the third sliding seat 703, the second lifting seat 705, and the push plate 708 are all driven by an external stepping motor and a screw rod. By driving the second lifting seat 705 to descend through the stepping motor and the screw rod, the cryopreservation rack lifting rod 706 can extend into the liquid nitrogen tank 1. Then, by driving the third sliding seat 703 to slide through the stepping motor and the screw rod, the cryopreservation rack lifting rod 706 can be stuck at the lower end of the storage plate 1101. At this time, by driving the second lifting seat 705 to rise through the stepping motor and the screw rod, the cryopreservation rack body 11 can be taken out.

[0057] Furthermore, the push plate 708 is used to push the cryopreservation box out of the storage plate 1101 when the sample is taken out of the warehouse.

[0058] Working principle: When storing a sample, place the transfer barrel body 3 at the upper end of the conveyor belt 203. Push the first sliding seat 204 upward through the electric push rod so that the end cover 301 at the upper end of the transfer barrel body 3 is clamped between the two elastic clamping blocks 4063. Then drive the rotating seat 4062 to rotate through the stepping motor so that the two elastic clamping blocks 4063 drive the end cover 301 to rotate, thereby removing the end cover 301 from the transfer barrel body 3. Then drive the second sliding seat 403 to move to the left through the stepping motor and the screw rod, so that the mechanical claw 409 is located directly above the transfer barrel body 3. Grab the cryopreservation box inside the transfer barrel body 3 by the contraction of the mechanical claw 409. After the mechanical claw 409 grabs the cryopreservation box, the second sliding seat 403 will reset. At this time, the cryopreservation box is located directly above the label reading mechanism 5, and the label reader 502 will sequentially scan the labels on the cryopreservation box and the test tube labels inside the cryopreservation box and store them in the numerical control module 10 to generate the corresponding storage positions. After the scanning is completed, the mechanical claw 409 places the cryopreservation box in the storage slot 603. Then, through the cooperation of the stepping motor and the screw rod, push the bearing seat 602 to move to the end of the fifth guide rail 601. At this time, the cryopreservation box is aligned with the storage port 901. Then drive the third lifting seat 803 to slide upward through the stepping motor and the screw rod to open the sealing cover 101, thereby opening the liquid nitrogen tank 1. Then drive the fourth sliding seat 801 to move to the right through the stepping motor and the screw rod, so that the sealing cover 101 moves away from directly above the storage port 901. After that, drive the second lifting seat 705 to descend through the stepping motor and the screw rod so that the cryopreservation rack lifting rod 706 extends into the liquid nitrogen tank 1. Then drive the third sliding seat 703 to slide through the stepping motor and the screw rod so that the cryopreservation rack lifting rod 706 is stuck at the lower end of the storage plate 1101. At this time, drive the second lifting seat 705 to rise through the stepping motor and the screw rod to pull out the cryopreservation rack body 11. When the upper end of the storage plate 1101 where the storage position of the cryopreservation box generated by the numerical control module 10 before is flush with the storage port 901, the cryopreservation rack body 11 stops moving. At this time, drive the side baffle 604 to rotate and open by driving the rotating shaft through the stepping motor. Then push the cryopreservation box outward through the electric push rod to push the cryopreservation box from the storage slot 603 to the upper end of the storage plate 1101. After that, place the cryopreservation rack body 11 back to its original position through the cryopreservation rack extraction mechanism 7 and reset the sealing cover 101 through the cover opening mechanism 8 to complete the warehousing operation. When the sample is taken out of the warehouse, perform the above operations in reverse.
