Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0022] Please refer to Figs. 1-2 The utility model provides a technical scheme:

[0023] A centrifugal cup test tool, comprising:

[0024] The main body structure comprises a box body 1 and a box cover 2, and the box cover 2 is installed on one side of the top opening of the box body 1.

[0025] Further comprising a test mechanism for testing the centrifugal cup; the test mechanism comprises a centrifugal well 3 and a peristaltic pump 4, the inner cavity of the box body 1 is provided with a base 8, one end of the base 8 is provided with the centrifugal well 3, the cup body 5 to be tested is placed in the centrifugal well 3, the inner wall of the centrifugal well 3 is provided with a detection sheet 7 for detecting whether the cup body 5 leaks, the detection sheet 7 is in contact with the outer wall of the cup body 5, and the peristaltic pump 4 is used for pumping physiological saline into the cup body 5.

[0026] The utility model discloses a main body structure comprising a box body 1 and a box cover 2, a test mechanism comprising a peristaltic pump 4 and a centrifugal well 3 is arranged in the box body 1, and a detection sheet 7 is arranged in the centrifugal well 3 and used for detecting whether the cup body 5 has quality problems; in actual use, the test tool can realize quality and performance tests of three kinds of centrifugal cup specifications with a capacity of 70ml, 125ml and 225ml, the cup body 5 with a pipeline is installed into the centrifugal well 3, the box cover 2 is covered, the rotating speed of a centrifugal machine module is set, operation is started, the peristaltic pump 4 is started to slowly suck physiological saline into the centrifugal cup through the liquid inlet pipe of the centrifugal cup (the physiological saline is automatically discharged from the liquid outlet after the centrifugal cup is full), and the state of the centrifugal cup is observed. In this way, the quality performance of the centrifugal cup and improvement measures are analyzed by setting and observing abnormal sound, leakage, rupture, shaking and other conditions of the centrifugal cup under different centrifugal cup rotating speeds, centrifugal cup liquid inlet speeds and centrifugal cup running durations.

[0027] The box cover 2 is integrally formed in transparent acrylic material, has high transparency, excellent rigidity, strength and excellent chemical resistance, and can play a good protection role and avoid splashing accidents caused by debris of defective products.

[0028] In general, the device has simple structure, convenient to use, through the cooperation of the main body structure and the detection mechanism, can carry out special quality test for the centrifugal cup under the premise of high safety and reliability, and the appearance is small and convenient to transport, the cost is cheap, saves the cost, facilitates the control of production quality and quickly verifies various defects of the centrifugal cup, improves the development progress, avoids the outflow of defective products, and ensures the personal safety of production, development and use personnel.

[0029] The peristaltic pump 4 is composed of a driver, a three-phase DC motor and a pump head. The peristaltic pump 4 extracts liquid in the same way as fingers pinch and squeeze a soft tube full of fluid, and the fluid in the tube moves forward as the fingers slide forward. The peristaltic pump 4 replaces the fingers with rollers, and pumps the fluid by alternately pressing and releasing the elastic conveying hose of the pump. The driver of the peristaltic pump 4 is a brushless driver for driving the brushless DC motor to provide power for the rollers, has the characteristics of automatic stop rotating to prevent accidents when the pump door is opened, real-time monitoring of the working state of the motor, and closed-loop servo control of the motor. Through the RS485 serial interface, real-time communication with the central controller is realized, the flow rate can be set to 8 to 1000 ml / min, and the standard pump pipe control precision is ±10%.

[0030] The base 8 is provided with a centrifuge module, and the centrifuge module is composed of a driver, a three-phase centrifugal motor and a centrifugal well 3.

[0031] Specifically, the centrifuge module is composed of a driver, a three-phase centrifugal motor and a centrifugal well 3. The driver is a brushless driver for driving the three-phase centrifugal motor to run at 0-7000 RPM. The centrifugal well 3 nests the centrifugal motor in the center, facilitates the installation and fixation of the centrifugal cup at the center of the centrifugal motor, and reduces the risk of the centrifugal cup breaking and being thrown out to hurt people. The centrifuge protection door is a device for completely enclosing the centrifugal cup in the centrifuge, which physically isolates the centrifugal cup from the outside world, and plays a double protection role. The central processing unit controls the operation of the centrifugal motor by interacting with the driver, and collects the real-time speed, current, voltage and temperature of the centrifugal motor in real time. If the speed is unstable, the current is too high, the voltage is too high, or the temperature is too high, the protection mechanism will be started to stop running.

[0032] The side outer wall of the box body 1 is provided with a wiring socket 9, and the wiring socket 9 includes a power supply module socket and a display screen module for connecting a display screen. The base 8 of the box body 1 is built-in with a control circuit board, and the control circuit board is integrated with a central processing unit. The central processing unit is electrically connected with the peristaltic pump 4, the externally connected display screen module, the centrifuge module and the power supply module.

[0033] Specifically, the display screen module is an HMI serial screen. The serial screen is first a touch screen, which can display characters, patterns, etc., and is touched and slid by fingers to control the screen and transmit information, and then it communicates with the controller by using serial communication. It has simple instructions, low GUI design threshold, and can greatly shorten the development time. The utility model interacts the HIM serial screen and the central processor through the serial port. The operator or user sends commands to the central controller through the serial port by manually touching the screen controls, and the central controller executes corresponding actions to control the peristaltic pump 4 module, liquid leakage module, centrifuge module, etc. and display the states of the modules on the HIM screen in real time.

[0034] The power supply module built in the box body 1 completes power supply and voltage conversion of the whole system. The power supply module mainly converts the 220V alternating voltage of commercial power into 24V direct current voltage and 48V direct current voltage (special for the centrifuge module) for use of various modules.

[0035] The detection sheet 7 is composed of two groups of superimposed copper sheets, and the FPC flexible flat cable and detection circuit matched with the detection sheet 7 are arranged in the base 8 of the box body 1.

[0036] In specific use, when the centrifugal cup breaks or has self-problems to cause liquid splashing out during high-speed operation, the splashing liquid reaches the two copper sheets of the FPC flexible flat cable, the resistance between the two copper sheets changes, the change is transmitted to the central processor through the detection circuit, and the central processor detects the liquid leakage and immediately stops the centrifuge from running to prevent accidents.

[0037] An opening 6 is formed in the top edge of the box body 1, and the opening 6 is used for the liquid inlet pipe and liquid outlet pipe of the cup body 5.

[0038] By arranging the opening 6 in the top edge of the box body 1, the liquid inlet pipe and liquid outlet pipe of the cup body 5 can pass through under the condition that the box body 1 and the box cover 2 are closed, and the convenience of the device is improved.

[0039] Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limiting the utility model, and those skilled in the art can change, modify, replace and transform the above embodiments within the scope of the utility model.
