Description

Field of technology The present invention relates to a swing-bucket rotor assembly for a centrifuge, and in particular to a swing-bucket rotor assembly for a centrifuge installed inside a centrifuge for centrifuging samples such as blood or bone marrow, and provided with an angle locking unit that maintains the angle of inclination of a tube holder in order to effectively unload centrifuged samples (blood, bone marrow, etc.), as well as a battery for driving the angle locking device. State of the art When a suspension of floating material remains, high-density substances slowly sink to the bottom under the force of gravity, while low-density substances slowly move to the top layer, a process called sedimentation. Thus, when substances with different densities are mixed, a precipitate forms, and the mixture can be separated over time based on the difference in density. Since the difference in density between mixtures increases with increasing gravity, which is the force that causes the mixture to separate, sedimentation can be accelerated by artificially increasing gravity. In other words, sedimentation can be easily accelerated using centrifugal force instead of gravity, a process called centrifugation. A centrifuge is a mechanism used to separate, purify, and concentrate materials with different components or specific gravities using the centrifugal principle. Depending on the intended use, centrifuges can be categorized into several types: for medical applications, wastewater treatment, uranium enrichment, industrial production, and experimental use. In particular, a medical centrifuge is used to separate components for analysis of blood, urine, saliva, and other samples. For example, platelet-rich plasma (PRP), obtained by centrifuging bone marrow or blood, refers to a plasma component with a high platelet content, containing more platelets than normal bone marrow or blood. PRP is injected into damaged areas, such as ligaments and cartilage, to be used for repair. This method uses the patient's own bone marrow or blood, so there are no side effects and the therapeutic effect is rapid. Based on this technical idea, Korean Patent No. 10-1387433 discloses a centrifugal separator and a tube holder that can utilize both the functions of a swing-bucket rotor and an angle rotor to realize the function of an angle rotor in a swing-bucket rotor by replacing the corresponding tube holder without replacing the entire rotor. According to the prior art, it is theoretically possible to increase the processing capacity by forming a plurality of blocks to be placed in a tube holder, to provide a tube holder suitable for various storage containers by changing the size and shape of the blocks to be placed in the tube holder, and to simultaneously perform separation using a swing-bucket rotor and separation using an angle rotor, even if one swing-bucket rotor is subjected to one centrifugation process according to the characteristics. However, centrifugation of the sample can be simplified according to the advantages described above, but in order to move the separated components to another space (chamber) after centrifugation inside the sample container, the sample needs to be unloaded while maintaining an inclined position at a predetermined angle, but here a problem arises that it is difficult to maintain the same angle for unloading the sample. Disclosure of invention Technical problem The aim of the present invention is to solve the said problems and to propose a bucket rotor assembly for a centrifuge comprising an angle fixing device in order to maintain the angle of inclination of the tube holder close to horizontal due to the action of centrifugal force when the rotor rotates in order to fix the angle of the decanting kit placed in the tube holder at the level at which it is located, and so that the sample contained in the decanting kit can be effectively separated. Technical solution According to one of the features of the present invention, a bucket rotor assembly for a centrifuge is proposed, mounted and rotating inside a centrifuge housing, characterized in that the bucket rotor assembly contains a drive unit consisting of a motor with a drive shaft, a mounting cap mounted on the upper part of the motor and provided with a flange on the lower edge, and a transmitting charging module secured to the mounting cap for wireless charging of the battery; a rotor collector having a housing inside which U-shaped curved parts are formed on both sides for securing a test tube holder, while it is mounted and rotates on the drive shaft of the motor, an angle fixing unit mounted inside the housing for controlling the angle of the test tube holder and unloading the centrifuged sample, a battery installed inside the housing for driving the angle fixing unit, a receiving charging module installed in the lower part of the housing for wireless charging of the battery, and a rotating shaft unit installed inside the housing and supp
