4results about How to "Realize fully automated detection" patented technology

The application discloses a torsion rod detection tool and an automatic detection equipment. The tool comprises a fixing assembly and a torsion detection assembly. The fixing assembly is formed by two fixing blocks with half-tooth grooves to form a first tooth groove meshing with a first tooth part of the torsion rod, so that reliable fixing is realized. The torsion detection assembly comprises a torsion block rotatably assembled on a mounting seat, the torsion block is provided with a second tooth groove capable of being radially assembled into a second tooth part of the torsion rod and a lever arm extending in the radial direction. The mounting seat is provided with a detection module and a driving module acting on two ends of the lever arm respectively. The driving module drives the lever arm to drive the torsion block to rotate, and the detection module accurately obtains a torsion angle by measuring the displacement of the lever arm and conversion based on a lever ratio. The tool is fast in clamping, reliable in positioning and high in detection precision. The corresponding automatic equipment integrates the tool, and realizes full-process automation of the torsion rod from automatic feeding, correction, function detection, appearance re-inspection to intelligent sorting.

This invention discloses a disc-shaped microfluidic chip detection kit and method, relating to the field of rapid food safety detection. A disc-shaped substrate has a ring-shaped central flow channel, and in the direction of rotation towards the central flow channel, a lysis buffer chamber, an elution buffer chamber, a first washing buffer chamber, a second washing buffer chamber, and a magnetic bead reagent chamber are arranged in a ring-shaped sequence. At least four reaction chambers are arranged in a ring-shaped interval in the direction away from the rotation axis of the central flow channel. A ring magnet is positioned on the bottom plate facing the central flow channel, and a pin for opening a contact valve is arranged around the periphery of the ring magnet. Two types of heating plates with temperature differences are respectively positioned on the heating plate facing the reaction chambers. This invention relies on centrifugal force to achieve autonomous fluid drive, combined with constant temperature zone control to complete rapid amplification. It not only eliminates cross-contamination problems caused by magnetic bead transport at the structural level, but also achieves a high degree of integration of the entire process from nucleic acid extraction to fluorescence amplification, effectively improving the overall detection efficiency of pathogens.

This application discloses a limit switch detection system, comprising: a microprocessor, a left-hand drive assembly, a right-hand drive assembly, a left-hand position sensor, a right-hand position sensor, and a signal acquisition circuit. The microprocessor is connected to the left-hand drive assembly, the right-hand drive assembly, the left-hand position sensor, and the right-hand position sensor. The left-hand drive assembly drives the limit switch to be detected to rotate to the left, and the right-hand drive assembly drives the limit switch to rotate to the right. The left-hand position sensor feeds back a first position signal to the microprocessor when the limit switch rotates to the left to a first specified angle, and the right-hand position sensor feeds back a second position signal to the microprocessor when the limit switch rotates to the right to a second specified angle. The signal acquisition circuit is connected to the limit switch and is also connected to the microprocessor. This application can improve the detection efficiency and accuracy of limit switches. This application can be widely used in the field of automation technology.
