Description

Technical Field

[0001] This utility model relates to the field of gripper technology, specifically to a gripper for picking up cryopreservation tubes. Background Technology

[0002] In the cryopreservation and experimental operations of biological samples, cryovials, as the core carrier unit of the sample, directly affect the integrity of the sample and the accuracy of the experiment by the precision of their handling and placement in the ultra-low temperature environment. Currently, cryopreservation tube picking uses a traditional gripper structure, which uses the clamping force of the gripper sidewalls to grab the cryopreservation tube and then transfer it to the corresponding hole in the cryopreservation box for release. However, during the picking process, it is necessary to reduce collisions and conflicts during clamping. That is, the gripper needs to be opened first and then reset during clamping. At the same time, it needs to be suitable for clamping cryopreservation tubes of different specifications. Therefore, it is necessary to design a gripper suitable for clamping cryopreservation tubes. In view of this, we propose a cryopreservation tube picking gripper. Utility Model Content

[0013] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] Please see Figures 1-7 The present invention will describe the above technical solution in detail through the following embodiments: The cryopreservation tube picking gripper in this embodiment includes a gripper fixing base 1 for providing a fixing foundation, such as... Figure 6 The structure shown has a cross-shaped inner groove 11 on the gripper fixing seat 1 and a shaft hole 101 at the shaft center.

[0015] A rotating disk 2 is rotatably installed in the groove 11 inside the gripper fixing seat 1. A push rod 3 is installed at the bottom axis of the rotating disk 2 and inserted through the shaft hole 101. In this embodiment, a distance sensor is installed at the bottom end of the push rod 3, which can maintain positioning when clamping the cryopreservation tube and prevent the clamp from derailing.

[0016] In this embodiment, a connecting shaft seat 5 is fixedly connected to the rotating disk 2 via an adjusting rod 4. The connecting shaft seat 5 is used to coaxially mount a drive motor as a power source. In order to realize the opening and closing clamping action of the gripper unit 6, this embodiment, for example... Figures 4-7 The structure shown has four evenly distributed centering guide grooves 102 in the embedded groove 11. The moving path of the centering guide grooves 102 is perpendicular to the axis of the gripper fixing seat 1 to ensure subsequent centering clamping.

[0017] Specifically, this embodiment is provided with four gripper units 6. Each gripper unit 6 includes an inverted U-shaped frame 62 inserted into the centering guide groove 102. A gripper plate 61 is detachably installed below the inverted U-shaped frame 62. At the same time, a transmission link 63 is rotatably installed between the inverted U-shaped frame 62 and the rotating disk 2. When the drive motor drives the rotating disk 2 to rotate, the transmission link 63 deflects, which in turn drives the gripper plate 61 to open and close through the inverted U-shaped frame 62, so as to facilitate clamping.

[0018] In order to maintain stability during the clamping process and avoid misalignment of the gripper plate 61, this embodiment has four slide rails 64 detachably installed at the bottom of the gripper fixing seat 1, which correspond to the reciprocating movement path of the inverted U-shaped frame 62 respectively. The gripper plate 61 is slidably installed on the slide rails 64 by the slider 65, so that the four gripper units 6 can complete the smooth opening and closing action.

[0019] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0020] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
