Description

Technical Field

[0001] This utility model relates to the field of label information extraction technology for cryopreservation tubes, and in particular to an automatic label information extraction device for cryopreservation tubes. Background Technology

[0002] Cryopreservation tubes generally refer to bacterial culture preservation tubes. They mainly consist of three parts: preservation solution, the tube itself, and small ceramic beads. These are containers used in laboratories to preserve or transfer bacterial cultures. Typically, each cryopreservation tube contains 25 small ceramic beads for bacterial adsorption and preservation. To facilitate the storage and management of bacterial cultures, and to enable rapid identification, location, and tracking of samples, labels are usually affixed to the top of the cryopreservation tubes. The label information is then extracted by scanning a barcode to identify the bacterial sample in each cryopreservation tube. Currently, barcode scanning is generally done manually using a handheld barcode scanner. However, manual scanning has the following drawbacks: prolonged operation leads to hand fatigue for staff, and the scanning speed is slow, resulting in low efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0004] Design an automatic label information extraction device for cryopreservation tubes, including a base, a gantry frame that can move forward and backward on the base via a longitudinal moving mechanism, a camera and a barcode scanner at the bottom of the crossbeam of the gantry frame via a transverse moving mechanism, a U-shaped mounting frame on the upper surface of the base located inside the gantry frame, and support frames for placing cryopreservation tubes on the inner walls of both sides of the mounting frame.

[0005] The upper surface of the base has movable slots at both ends that mate with the two legs of the portal frame. The two legs of the portal frame are slidably disposed in the movable slots. The longitudinal moving mechanism includes a threaded rod rotatably disposed in one of the movable slots, a longitudinal drive motor coaxially connected to the threaded rod, and a guide rod fixed in the other movable slot. One leg of the portal frame is threadedly engaged with the threaded rod, and the other leg is slidably disposed on the guide rod.

[0006] Preferably, the lateral movement mechanism includes a lead screw rotatably mounted on the inner wall of the two legs of the portal frame, a moving block threaded with the lead screw, and a lateral drive motor mounted on the outer wall of one leg of the portal frame. The top of the moving block is slidably connected to the inner top wall of the portal frame. The output shaft of the lateral drive motor is coaxially mounted with the lead screw. The camera and the barcode scanner are both mounted on the bottom of the moving block.

[0007] Preferably, a support column is provided between the bottom of the mounting bracket and the base.

[0008] Preferably, grooves are provided on the inner walls of both sides of the mounting bracket, and a slider is slidably provided in each groove, with the support frame positioned between the two sliders.

[0009] Preferably, a clamping mechanism is provided on the inner walls of both sides of the mounting frame above the support frame. The clamping mechanism includes a mounting plate fixed to the inner wall of the mounting frame, a slide rod passing through the mounting plate, a pull handle and a pressure plate respectively connected to the top and bottom of the slide rod, and a compression spring fitted on the slide rod. The two ends of the compression spring are respectively connected to the pressure plate and the fixing plate, and the pressure plate abuts against the upper surface of the support frame.

[0010] Preferably, a rubber anti-slip pad is provided at the bottom of the pressure plate.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a longitudinal moving mechanism, enables the gantry frame to move stably forward and backward on the threaded rod, realizing the scanning and photographing of each row of cryopreservation tubes. The lateral moving mechanism is set on the gantry frame, and through the moving block, drives the camera and barcode scanner at the bottom to move left and right on the screw, realizing the scanning and photographing of each row of cryopreservation tubes. This allows for the extraction of label information from all cryopreservation tubes, and the photographed and scanned label information is stored in the computer, facilitating later management and retrieval. Compared with traditional manual barcode scanning, it is faster and more efficient.

[0013] 2. This utility model uses sliders fixed at both ends of the support frame and slides in the grooves on the inner walls of both sides of the mounting frame to facilitate the removal of the support frame. The pressure plate in the pressing mechanism presses the support frame, so that the cryopreservation tube is placed more stably in the insertion hole in the support frame when scanning.

The longitudinal moving mechanism includes a threaded rod 3 rotatably mounted within one of the movable slots 2, a longitudinal drive motor 15 coaxially connected to the threaded rod 3, and a guide rod 14 fixed within the other movable slot 2. One leg of the gantry frame 7 is threadedly engaged with the threaded rod 3, while the other leg slidably passes through the guide rod 14. The two legs of the gantry frame 7 move within the movable slots 2, thus providing the gantry frame 7 with a defined trajectory during movement, resulting in greater stability.

[0021] A camera 10 and a barcode scanner 11 are installed at the bottom of the crossbeam of the portal frame 7 via a lateral moving mechanism. The lateral moving mechanism includes a lead screw 8 rotatably mounted on the inner wall of the two legs of the portal frame 7, a moving block 9 threadedly engaged with the lead screw 8, and a lateral drive motor 12 mounted on the outer wall of one leg of the portal frame 7.
