[0031] Example 1

[0032] like Figures 1 to 7 As shown, this utility model provides a technical solution:

[0033] A centrifuge RFID rotor intelligent management system includes, but is not limited to, a rotor 1, a motor assembly 2, and a connector 3; an RFID chip card 4 is provided on the rotor 1, and an RFID antenna 5 that cooperates with the RFID chip card 4 is provided on the connector 3; the output end 6 of the motor assembly 2 is connected to the rotor 1; and the RFID antenna 5 is connected to an external card reader via a line.

[0034] Based on the above structure, in this solution, the RFID chip card 4 is set together with the rotor 1. The RFID chip card 4 can record information about the rotor 1, such as the rotor 1's factory information, rotor 1's operating parameters, rotor 1's operating time records, etc. The RFID antenna 5 can realize contactless identification of the rotor 1, enabling the safe operation of the rotor 1. At the same time, the electronic tag can be quickly read and written through the reader, and the rotor 1's operating parameters and service life can be managed through data interaction, making the centrifuge rotor 1 safer and more efficient in use.

[0035] As an example, the rotor 1 may include a bearing cavity 11, a connecting channel 12, and a base 13; the connecting channel 12 is located at the center of the rotor 1, and multiple bearing cavities 11 are arranged around the connecting channel 12 with evenly spaced adjacent bearing cavities 11; the base 13 is provided with a cavity structure for accommodating the RFID chip card 4.

[0036] Based on the above structure, the connecting channel 12 of the rotor 1 is fixedly connected to the output end 6 of the motor assembly 2. The bearing cavity 11 is used to place the test tubes to be centrifuged. The bearing cavity 11 is evenly arranged so that the force on each test tube is more balanced during centrifugation. The RFID chip card 4 is placed on the base 13 of the rotor 1, which can facilitate the interaction between the RFID antenna 5 and the RFID chip card 4 in the later stage.

[0037] As an example, the base 13 is provided with an annular groove 14, and a support seat 15 that mates with the connecting channel 12 is provided at the center of the annular groove 14; the support seat 15 is provided with mating holes 16 for mating installation, and there are four mating holes 16 on the support, and the four mating holes 16 form a cross structure, that is, the central angle between adjacent mating holes 16 is 90°.

[0038] Assembly holes 17 are provided in the annular groove 14, the central angle between adjacent assembly holes 17 is 90°, and the central angle between adjacent mating holes 16 and assembly holes 17 is 45°.

[0039] Based on the above structure, the installation and removal of the RFID chip card 4 can be facilitated by setting the assembly hole 17, reducing the difficulty and cost of later maintenance; at the same time, the misalignment of the mating hole 16 and the assembly hole 17 can avoid interference during assembly and simplify the installation difficulty.

[0040] As an example, an annular cover 18 is provided in the annular groove 14; the size of the annular cover 18 is matched with the size of the annular groove 14, and a first supporting annular wall 181 and a second supporting annular wall 182 are provided on the end face of the annular cover 18 near the annular groove 14; the first supporting annular wall 181 is arranged around the outer diameter of the support base 15, and the second supporting annular wall 182 is arranged around the outer diameter of the annular groove 14.

[0041] The height of the first support ring wall 181 and the height of the second support ring wall 182 are set to be the same.

[0042] Based on the above structure, by setting the first support ring wall 181 and the second support ring wall 182, a cavity is provided between the ring groove 14 and the annular cover 18. The RFID chip card 4 is placed in this cavity structure. Since the annular cover 18 is a rigid structure, damage to the RFID chip card 4 can be effectively avoided after assembly.

[0043] As an example, a chip mounting base 183 is provided on the first support ring wall 181 and the second support ring wall 182 bracket; the chip mounting base 183 is made of nylon material, a first connecting hole is provided in the annular cover 18, and a second connecting hole is provided in the chip mounting base 183 to cooperate with the first connecting hole; a chip receiving groove 184 is provided in the chip mounting base 183.

[0044] Based on the above structure, by providing a second connecting hole in the chip mounting base 183, the chip assembly can be quickly positioned. This is achieved by passing a bolt through the first and second connecting holes. On the one hand, assembly can be achieved quickly and accurately. On the other hand, after the chip mounting base 183 is fixed, the position of the RFID chip card 4 can also be accurately determined, so that the RFID chip card 4 can be installed in the predetermined position.

[0045] As an example, the thickness of the RFID chip card 4 is no greater than the height of the chip receiving slot 184.

[0046] Based on the above structure, when the annular cover 18 is connected to the annular groove 14 by bolts, the nylon chip mounting base 183 provides a buffer for the whole, preventing the annular cover 18 from damaging the RFID chip card 4 during the assembly process, thus improving the assembly yield. At the same time, the nylon chip mounting base 183 can also protect the RFID chip card 4 during the movement of the rotor 1, preventing damage to the RFID chip card 4 during high-speed centrifugal action.

[0047] As an example, the connector 3 includes a first end 31 and a second end 32; the first end 31 faces the base 13 of the rotor 1, and the second end 32 faces the output end 6 of the motor assembly 2; an avoidance channel 33 is provided between the first end 31 and the second end 32 to avoid the output end 6 of the motor assembly 2, and the RFID antenna 5 is disposed on the first end 31.

[0048] Based on the above structure, the connecting seat 3 is set on the motor assembly 2. Its internal clearance channel 33 can avoid interference with the rotating motor output end 6, so that the entire connecting seat 3 is set on it stably. The RFID antenna 5 can stably cooperate with the RFID chip card 4 to realize the determination of the rotor 1 information.

[0049] As an example, an antenna slot 34 and a wire passage slot 35 are provided on the first end 31; the wire passage slot 35 is located close to the clearance slot and runs through the entire connector 3; the RFID antenna 5 is fixedly installed in the antenna slot 34 by bolts, and its lines are connected to the lines of the motor assembly 2 outward through the wire passage slot 35.

[0050] The second end 32 is provided with a snap-fit ​​cavity; the snap-fit ​​cavity is an overall flared structure, and the smallest part of the snap-fit ​​cavity is adapted to the size of the motor assembly 2, so that the motor assembly 2 can be snapped into the snap-fit ​​cavity. A locking hole 36 is provided on the side wall of the snap-fit ​​cavity, and a bolt passes through the locking hole 36 to connect the second end 32 and the motor assembly 2 as a whole. The connecting seat 3 can be made entirely of nylon material.

[0051] Based on the above structure, by setting the second end 32 as an flared shape, it is convenient to connect with the motor assembly 2, so as to realize the quick assembly of the connecting seat 3 and the motor assembly 2. At the same time, the two are locked by passing the bolt through the locking hole 36. The RFID antenna 5 is set in the antenna slot 34, which can realize the content recognition of the RFID chip card 4 more accurately.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
