Description

Technical Field

[0001] This utility model relates to the field of cryopreservation tube clamp technology, specifically to a cryopreservation tube spring clamp. Background Technology

[0002] In the cryopreservation and experimental operation of biological samples, cryovials are the core carriers of the samples. The accuracy of their grasping and placement in the ultra-low temperature environment directly affects the integrity of the samples and the accuracy of the experiments. At present, cryovial picking mostly adopts the traditional gripper structure, which grasps the cryovial through the clamping force of the gripper sidewall and then transfers it to the corresponding hole in the cryopreservation box for release.

[0003] However, in low-temperature environments ranging from -20℃ to -80℃, the outer wall of cryovials is prone to cold adhesion to the inner wall of the grippers or the cryovial container due to factors such as condensation and reduced molecular activity of the material. When the grippers are cold-adhesive, the adhesive force will prevent the cryovials from being removed from the cryovials or released from the grippers, which may cause the cryovials to deviate from the preset trajectory during the fall, resulting in positional deviation, tilting, tipping, or even collision damage, directly threatening the safety of the samples. In addition, traditional grippers lack auxiliary mechanisms for releasing or ejecting cryovials, which cannot fundamentally solve the cold adhesion problem and cannot meet the needs of high-precision automated operation of biological samples. In view of this, we propose a cryovial spring clamp. Utility Model Content

It also includes: Mobile parts, such as Figures 1-4 The structure shown includes an active moving frame 2 that is horizontally and backward movable on the mounting frame 1, and a moving plate 6 that is horizontally and slidably mounted on the active moving frame 2. In this embodiment, in order to realize three-dimensional movement and to realize the picking and placing of cryopreservation tubes at different locations, the active moving frame 2 includes a vertical plate 21 with a horizontal plate 22 detachably mounted at one end. A first slide rail 23 and a first gear plate 24 are mounted in parallel on the vertical plate 21, and an active motor 3 is mounted on the horizontal plate 22.

[0018] like Figure 3 The structure shown has a second moving track 11 horizontally mounted on the mounting frame 1 for sliding the second slider 12. A horizontal plate 22 is mounted through the second slider 12. In order to achieve horizontal forward and backward drive, a second gear plate 13 that meshes with the output shaft of the active motor 3 is fixedly mounted on the mounting frame 1. The drive gear mounted on the output shaft of the active motor 3 moves back and forth along the direction of the second gear plate 13.

[0019] like Figure 3 , Figure 4 As shown in the structure, the movable plate 6 is vertically mounted on an L-shaped lifting frame 16 via a vertical plate 15, and a pin 18 is vertically mounted on the outer end of the L-shaped lifting frame 16; the movable plate 6 is slidably mounted on the first slide rail 23 via a first slider 25, and the movable plate 6 is driven by the gear 41 of the drive motor 4 meshing with the first gear plate 24 to achieve left and right movement.

[0020] To achieve vertical movement for lifting and lowering, a vertically installed threaded rod 7 is mounted on the moving plate 6 via a lifting motor 5. The lifting plate 8 is threaded onto the threaded rod 7, and the lifting plate 8 moves vertically up and down via a slide rail. Meanwhile, an infrared sensor 10 for positioning cryopreservation tubes is detachably installed below the lifting plate 8.

[0021] In this embodiment, the gripper part includes a vertically lifting support plate 8, and a gripper top support unit 9 for gripping the cryopreservation tube is installed below the lifting support plate 8. The gripper top support unit 9 is set to be coaxial with the ejector pin 18, so that the ejection and gripping actions of the cryopreservation tube are consistent and the axial position is accurate.

[0022] like Figures 1-4 As shown, in this embodiment, an L-shaped lifting frame 16 is vertically slidably installed on the vertical plate 15 via a third moving track 151, and a top support motor 17 is installed on the vertical plate 15 to drive the L-shaped lifting frame 16 to rise and fall.
