AI Technical Summary

Technical Problem

Existing automated decapsulation systems are complex and inflexible when dealing with multiple sample tube heights and diameters, and require additional cleaning operations, increasing system complexity and resource consumption.

Method used

A decap device including a latch mechanism, a clamper and a traction device is designed, which extends and retracts through a motor drives the latch mechanism, the clamper rotates and clamps the sample tube, and the traction device slides and moves the clamper to realize automatic decapsulation of sample tube covers of different heights and diameters, and automatically ejects the decapsulated cover through the ejector.

Benefits of technology

Automatic decapsulation of multiple sample tube heights and diameters is achieved, simplifying the system structure, reducing additional cleaning operations, and improving system flexibility and efficiency.

Abstract

A kind of decapping device, this decapping device can be combined with automated biochemical analyzer or biological testing system to facilitate sample testing.Exemplary decapping device includes a motor, which can operate: lowering a latch mechanism to engage with the lid of a sample tube, and then raising the latch mechanism to remove the engaged lid.As the latch mechanism is lowered, the tractor portion also descends and causes a group of grippers to extend and clamp the sample tube.As the latch mechanism is raised, the group of grippers apply corresponding pressure to keep the sample tube in place while the lid is removed.Once removed, the lid is resting in the latch mechanism, and the group of grippers is retracted by the raised tractor.When the latch mechanism returns to its initial position, the ejector arm is operated, causing the lid to be ejected from the latch mechanism.
