Description

Technical Field

[0001] The invention relates to the technical field of laboratory equipment centrifuges, and in particular to a centrifuge capable of identifying the operating state of a rotor by color. Background Art

[0002] Laboratory centrifuge, or experimental centrifuge, is a small centrifuge specially used for experimental analysis. Centrifuge is an instrument that separates fractions of different density and molecular weight in a substance by causing an object rotating around a fixed axis to undergo sedimentation under the influence of centrifugal force, simulating the earth's gravitational field. The technology of analyzing and separating substances by centrifugal sedimentation is called centrifugal technology. At present, various centrifuges and centrifugal technologies have been widely used in scientific research and production departments, and have become one of the important instruments and equipment for modern scientific research. Laboratory centrifuge is an essential equipment for scientific research and production in biology, medicine, agronomy, bioengineering, biopharmaceuticals and other industries.

[0003] Some devices in the current technical field cannot add rotor recognition function due to lack of technology, cost restrictions, or restrictions on usage or internal structure. The main purpose of identifying the rotor is to ensure the safety of machine use. The rotor recognition function can ensure that the centrifuge does not exceed its maximum speed during operation, thereby avoiding serious accidents caused by excessive speed, such as rotor deformation, cracking or even breaking, which may cause great personal injury to the operator.

[0004] Specifically, each centrifuge rotor has its own speed limit. If the operator mistakenly sets a speed higher than the speed limit, the system will automatically correct the set speed to ensure that it operates within the safe range and remind the operator that the set speed exceeds the safe range. In addition, the rotor recognition function can also record the operating time of each rotor, and remind the operator to replace the new rotor when the allowed operating time is exceeded, thus replacing the previous manual recording method. Therefore, the application of rotor recognition technology not only improves the safety of the equipment, but also simplifies the operating process and reduces the possibility of human error.

[0005] The rotor identification methods of laboratory centrifuges are known to have Hall induction identification, which mainly works through the magnetic force of the magnet and Hall induction. The Hall and magnet induction methods are subject to changes in factors such as the magnetic force and the Hall induction distance, and there are large errors. There are often large vibrations during the operation of the centrifuge, which often lead to induction errors and alarms, greatly affecting work efficiency.

[0006] In view of the above problems, how to improve the working efficiency of laboratory centrifuges has become a technical problem that people urgently need to solve. Summary of the invention

The circuit board assembly controls the motor main shaft to rotate at a corresponding speed according to the relevant information set by the program to drive the rotor fixed thereon to rotate, thereby completing the power-on, rotor installation, rotor recognition and operation cycle of the entire equipment.
