Self-locking intelligent mechanical gripper for high-throughput nucleic acid sample pipetting workstation

Abstract

The invention discloses a self-locking intelligent mechanical gripper for a high-throughput nucleic acid sample pipetting workstation. The self-locking intelligent mechanical gripper comprises a rotary positioning control component, a fixing plate, a gripper opening and closing control component and a mechanical finger pressure acquisition and control component. The rotary positioning control component, the fixing plate and the gripper opening and closing control component are sequentially connected from top to bottom. The mechanical finger pressure acquisition and control component is arranged on the gripper opening and closing control component. The self-locking intelligent mechanical gripper can be flexibly controlled by the rotary positioning control component to rotate by 360 degrees, and the gripper opening and closing control component is in cooperation with a pressure feedback module to set the gripping pressure of mechanical fingers on laboratory consumables in a self-adaptive manner according to the material, the shape and the size of pipetting consumables, so that laboratory consumable deformation, slippage and the like in the pipetting gripping process can be avoided; the different laboratory consumables in any position in any direction of the automatic nucleic acid pipetting workstation can be gripped and transferred quickly, flexibly and stably, and the experiment expansion is facilitated.

Description

technical field [0001] The invention relates to the technical field of automation of high-throughput nucleic acid detection and pipetting workstations for medical devices, in particular to a self-locking intelligent mechanical gripper for high-throughput nucleic acid sample pipetting workstations. Background technique [0002] In the context of the continuous strengthening of the globalization process, various known or unknown diseases have broken out on a large scale. In order to detect the disease more quickly, accurately and safely, the research of high-throughput nucleic acid detection system is of great significance. The experimental platform of the automated pipetting workstation can greatly optimize the experimental efficiency. A complete round of experiments requires a variety of consumables containing sample reagents. In order to facilitate the expansion of the experimental program, the experimental consumables need to be transferred between different stations. Duri...

AI Technical Summary

Problems solved by technology

However, the size, shape, and rigidity of the experimental consumables are different, which brings certain difficulties to the fast and stable grasping and transfer of the mechanical grippers. Problems such as excessive grip force, deformation of the consumables, and slipping during the transfer of the consumables often occur. This can lead to adverse results such as experiment termination or virus contamination.
