Control mechanical arm, molecular hybridization instrument and operation method of control mechanical arm

Abstract

The invention discloses a control mechanical arm, a molecular hybridization instrument and an operation method of the control mechanical arm. A suction head operation mechanism, a liquid adding and discharging operation mechanism and a control mechanism are arranged on the control mechanical arm, wherein the suction head operation mechanism comprises a vertical translation guide plate, suction head assembling and disassembling tubes and a suction head removing baffle plate; a plurality of suction head assembling and disassembling tubes are arranged on the vertical translation guide plate; assembling and disassembling parts of the suction head assembling and disassembling tubes are arranged below the vertical translation guide plate; the suction head removing baffle plate is arranged belowthe vertical translation guide plate; the assembling and disassembling parts of the suction head assembling and disassembling tubes pass through the through holes in the suction head removing baffle plate; the control mechanism comprises a first vertical translation driving mechanism and a pneumatic control mechanism; the first vertical translation driving mechanism is in driving connection with the suction head operation mechanism; the suction head assembling and disassembling tubes are connected with the pneumatic control mechanism through a first connection tube. The control mechanical armcan be applied to the molecular hybridization instrument, is provided with the liquid adding and discharging operation mechanism, is simple in structure and high in automation degree, and is capable of reducing manual operation as far as possible and improving the operating efficiency.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a manipulation manipulator that can be applied to a molecular hybridization instrument, a molecular hybridization instrument using the manipulation manipulator, and a working method for the manipulation manipulator. Background technique [0002] Molecular hybridization instrument, also known as: molecular hybridization box, molecular hybridization oven, is widely used in the screening of cloned genes, the production of enzyme digestion maps, the qualitative and quantitative detection of specific gene sequences in the genome, and the diagnosis of diseases. Molecular hybridization instruments are not only widely used in the field of molecular biology, but also increasingly used in clinical diagnosis. [0003] The basic principle of the molecular hybridization instrument is to use the properties of denaturation and renaturation of nucleic acid molecules to make DNA (or RNA) fra...

AI Technical Summary

Problems solved by technology

[0004] With the wide application and promotion of molecular hybridization instruments, people have higher and higher requirements for the use of molecular hybridization instruments. Most of the existing manipulators of molecular hybridization instruments have complex structures, simple functions, and insufficient automation. The related operations are performed artificially, which reduces the work efficiency of people. Secondly, the liquid feeding and discharging mechanism of the manipulator is separated, which increases the structural parts of the manipulator and takes up more space of the molecular hybridization instrument.
