Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically a centrifuge with identification function. Background Technology

[0002] Centrifuges are widely used equipment in laboratories, medical fields, and bioengineering, primarily used to separate substances of different densities through high-speed rotation. Traditional centrifuge operation mainly relies on manually setting parameters such as rotation speed, time, and temperature. Users need to input relevant parameters one by one according to experimental requirements, which is not only cumbersome but also prone to human error leading to deviations in experimental results, affecting the consistency and reproducibility of experiments.

[0003] In a multi-user shared environment, the frequent switching of user settings increases the complexity of operation and the probability of errors. In addition, there is the possibility of unauthorized personnel using the centrifuge or using non-standard test tubes for centrifugation. Utility Model Content

[0004] The purpose of this invention is to provide a centrifuge with identification function, which has the advantages of automatic parameter matching, centrifugation log recording, and prevention of misoperation. It solves the problems of increased operational complexity and error probability caused by frequent switching of user settings in a multi-user shared environment, as well as the problem of unauthorized personnel using the centrifuge or centrifuging with non-standard test tubes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centrifuge with identification function, including a centrifuge casing and a cover, wherein a touch screen and a barcode scanning mechanism are provided on the front end face of the centrifuge casing;

[0006] The cover is mounted on the upper surface of the centrifuge casing and is rotatably connected to it via a hinge. The scanning mechanism includes a camera, LED light cores, and a protective plate. A conical groove is provided on the front end face of the centrifuge casing. The camera is fixedly installed in the conical groove. The LED light cores are evenly installed on the outer side of the conical groove. The protective plate is detachably installed on the front end of the conical groove. A control mainboard is provided inside the centrifuge casing.

[0007] As a preferred embodiment of the centrifuge with identification function according to this utility model, a light guide cover is provided on the outer side of the LED lamp core, and the light guide cover has a ring structure.

[0008] As a preferred embodiment of the centrifuge with identification function according to this utility model, a reflector is provided on the back of the LED light core, and the reflector has an arc-shaped structure.

[0009] As a preferred embodiment of the centrifuge with identification function according to this utility model, the side end face of the conical groove is provided with a positioning groove that slides with the protective plate, and the protective plate is made of transparent material.

[0010] As a preferred embodiment of the centrifuge with identification function according to this utility model, the front end face of the protective plate is provided with a pressure strip, the outer end face of the pressure strip is uniformly provided with arc-shaped protrusions, the inner end face of the positioning groove is provided with a slot that cooperates with the arc-shaped protrusions, and the inner side of the pressure strip is provided with an arc-shaped groove.

[0011] As a preferred embodiment of the centrifuge with identification function according to this utility model, the control motherboard is equipped with a data processing chip and a wireless module.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model significantly improves the intelligence and efficiency of operation by coordinating the front-end integrated touch screen, barcode scanning mechanism, and built-in control motherboard. Users only need to scan the QR code on their work badge, and the data processing chip will immediately parse the QR code, automatically match and preset the centrifugation parameters specific to that user, and transmit the operation record back for archiving in real time via a wireless module. This structural design and working mechanism completely solves the problem of cumbersome and error-prone manual parameter input in traditional centrifuges, realizing "scan and use," greatly shortening the operation preparation time. It is especially suitable for laboratory environments with multiple users and high frequency of use. At the same time, the automatic association with preset values ​​eliminates the risk of human error in setting, ensuring the consistency and repeatability of experiments, and the complete data chain provides a solid foundation for quality traceability and auditing.

[0014] 2. This utility model uses LED light cores to form soft and uniform ring lighting under the uniform light scattering of the light guide cover and the light focusing and enhancement effect of the reflector. This effectively overcomes the recognition interference caused by insufficient ambient light or glare from the nameplate, ensuring that the camera accurately captures information and avoiding recognition failure caused by strong light spots or insufficient light. The protective plate is quickly snapped and fixed by the sliding positioning groove on the side and the pressure strip with the arc-shaped protrusion at the front end and the arc-shaped groove that is easy to pry open. It is easy for users to disassemble and replace, greatly reducing downtime maintenance time and professional repair needs. Moreover, the corrosion-resistant material meets the strict cleaning and disinfection requirements of the laboratory. Attached Figure Description

[0021] Please see Figures 1-5 A centrifuge with identification function includes a centrifuge casing 1 and a casing cover 2. The front face of the centrifuge casing 1 is provided with a touch screen 3 and a barcode scanning mechanism 4.

[0022] The cover 2 is installed on the upper end face of the centrifuge casing 1 and is rotatably connected to it via a hinge 101. The barcode scanning mechanism 4 includes a camera 401, an LED light core 402, and a protective plate 403. A conical groove 104 is provided on the front end face of the centrifuge casing 1. The camera 401 is fixedly installed in the conical groove 104. The LED light core 402 is evenly installed on the outer side of the conical groove 104. The protective plate 403 is detachably installed on the front end of the conical groove 104. A control main board 103 is provided inside the centrifuge casing 1.

[0023] Furthermore, the centrifuge casing 1 is equipped with a rotor, and the rotor has a cavity for accommodating test tubes. The output shaft of the motor drives the rotor to rotate, thereby achieving high-speed centrifugation of the test tubes. It also includes a control system that adjusts the rotation speed and times the centrifugation time.

[0024] Furthermore, a light guide cover 404 is provided on the outer side of the LED lamp core 402. The light guide cover 404 has a ring structure and is made of PC material.

[0025] The white light guide 404 refracts, reflects, and scatters the LED point light source multiple times, making the light distribution uniform and forming a soft ring-shaped surface light source effect. This provides supplementary lighting for the QR code on the work badge when the light is insufficient, and avoids the work badge reflecting light due to excessive point light source light, which would affect scanning.

[0026] Furthermore, a reflector 405 is provided on the back of the LED chip 402, and the reflector 405 has an arc-shaped structure.

[0027] The reflector 405 reflects and enhances the light intensity of the LED core 402, thereby improving the supplementary lighting effect on the QR code on the work badge.

[0028] Furthermore, the side end face of the tapered groove 104 is provided with a positioning groove 1041 that slides with the protective plate 403, and the protective plate 403 is made of transparent material.

[0029] The sliding connection of the protective plate 403 structure makes it easy to disassemble and replace, avoiding wear or corrosion. It also ensures the accuracy of the equipment's barcode scanning. The transparent material is transparent polypropylene, which has high light transmittance and is corrosion-resistant and high-temperature resistant.

[0030] Furthermore, the front end face of the protective plate 403 is provided with a pressure strip 406, the outer end face of the pressure strip 406 is uniformly provided with arc-shaped protrusions 4061, the inner end face of the positioning groove 1041 is provided with a slot 1042 that mates with the arc-shaped protrusions 4061, and the inner side of the pressure strip 406 is provided with an arc-shaped groove 4062.

[0031] The protective plate 403 is fixed by the snap-fit ​​strip 406 to prevent it from falling off. The inner end face of the strip 406 is provided with an arc groove 4062, which makes it easy to pry up the strip 406 with a fingernail or other object to replace the protective plate 403.

[0032] Furthermore, the control motherboard 103 is equipped with a data processing chip 1031 and a wireless module 1032.

[0033] Furthermore, the wireless module 1032 is one of a WiFi module, a Bluetooth module, an IoT module, and a mobile communication module.

[0034] The data processing chip 1031 processes the QR code information recognized by the barcode scanner, matches it with parameters related to the user, and presets them to facilitate the user's quick centrifugation operation, reduce the risk of errors, prevent unauthorized personnel from operating, and prevent the user from using non-compliant test tubes. Finally, the wireless module 1032 transmits the data back for archiving.

[0035] Furthermore, an electric telescopic rod 102 is provided inside the centrifuge casing 1 and is rotatably connected thereto. The top of the electric telescopic rod 102 is rotatably connected to the casing cover 2.

[0036] The opening and closing of the cover 2 is controlled by the extension and retraction of the electric telescopic rod 102, which works in conjunction with the control main board 103. Only authorized personnel in the laboratory can open the cover 2 for use.

[0037] When using this device, first ensure that the equipment is powered on and in standby mode. At this time, the touch screen 3 will light up and display the initial interface. The operator needs to align their personal ID card or authorized QR code with the scanning mechanism 4 located at the conical groove 104 on the front face of the centrifuge casing 1. The LED light core 402 provides uniform and soft supplementary light under the action of the light guide cover 404 and the reflector 405, avoiding glare that may affect the scanning. The protective plate 403 is made of transparent polypropylene, which protects the internal camera 401 without affecting light transmission. After the camera 401 successfully scans and recognizes the QR code, the data is transmitted to the control motherboard 103 for data processing. Chip 1031 automatically matches the user's preset centrifugation parameters, such as speed and time, and displays them on the touch screen 3. The operator can directly confirm or fine-tune the parameters. Subsequently, the control motherboard 103 sends a command to the electric telescopic rod 102. The telescopic rod extends and pushes the cover 2 to rotate upward around the hinge 101 to open it. Authorized personnel can then place the sample. After the sample loading is completed, the start button is clicked on the touch screen 3. The electric telescopic rod 102 retracts and closes the cover 2. The centrifuge starts running according to the set parameters. During operation, the data is transmitted back to the laboratory management system for archiving via the wireless module 1032.

[0038] When authorizing personnel, a valid identification code is scanned using a 401 camera. The identification code can be a QR code or a barcode. The valid identification code is generated based on the unique machine number of each machine. Multiple identification codes can be generated. The software for generating identification codes is independent of the centrifuge and is installed on the computer. The identification code can be one-time use or reusable. The identification code can be issued based on the operator or used as an identification code for centrifuge tubes.

[0039] The centrifuge's centrifugation program can only be started after scanning a valid identification code, preventing unauthorized personnel from operating the machine or using non-compliant test tubes. It also automatically sets relevant parameters based on the characteristics of the operator or the test tubes used.

[0040] The above are merely preferred embodiments of the present utility model and are 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.
