Technical Field

[0001] The utility model relates to the technical field of iron-carbon pressure drop testers, in particular to a high-precision iron-carbon pressure drop tester. Background Art

[0002] When assembling electrodes, due to differences in the materials themselves, or differences in assembly processes and assembly levels of assemblers, the quality of electrode assembly will eventually vary greatly. Electrodes with poor tissue quality have high resistance and poor conductivity, and high losses in the later production process, resulting in a large amount of electric energy being wasted and reducing the economic benefits of the factory. By using an iron-carbon voltage drop tester, the resistance and voltage drop of the assembled electrodes can be directly measured, and the experimental current, resistance, and voltage drop data can be displayed on the display screen.

[0003] The iron-carbon voltage drop tester adopts a DC large current constant current source with a maximum of 500A, which makes the measurement result more accurate. The iron-carbon voltage drop tester can output continuously and stably for a long time, overcoming the disadvantage that the pulse power supply can only output instantly, resulting in inaccurate test data, so that it can timely and conveniently grasp the detailed data after the electrode assembly, and display the experimental current, resistance, and voltage drop data on the display screen to judge the quality of the assembly, so as to timely correct the assembly materials or modify the assembly process, and strengthen the control of the assembly quality. Since the iron-carbon voltage drop tester needs to use an electrical socket to connect to the power supply when it is used, when the electrical socket is accidentally disconnected from the iron-carbon voltage drop tester, it is easy to cause the test data to be lost or incomplete, thereby affecting the accuracy of the test results. Therefore, we propose a high-precision iron-carbon voltage drop tester. Utility Model Content

[0024] In specific implementation, according to Figure 1-Figure 3The iron-carbon voltage drop tester adopts a DC high-current constant current source with a maximum of 500A, which makes the measurement result more accurate. The iron-carbon voltage drop tester can output continuously and stably for a long time, overcoming the disadvantage that the pulse power supply can only output instantly, resulting in inaccurate test data, so that it can grasp the detailed data of the electrode after assembly in a timely and convenient manner. The iron-carbon voltage drop tester adopts a four-terminal test method, and the electrode device is placed inside the sample tray of the loading module. The sample tray of the loading module is a platform for placing electrode samples to maintain the stability of the samples and ensure that they remain in the correct position during the test. The pneumatic clamp of the loading module is used to clamp the electrode device being tested to ensure the stability and reliability of the test connection. The test parameter control panel of the test parameter module can be used to input the test parameters through the digital control software. The required test conditions, such as current, voltage, and measurement time, are set on the device. A certain current is provided by a constant current source, which passes through the electrode device to be tested. The voltage sensor of the voltage detection module is used to convert the voltage change generated on the electrode device into an electrical signal, and the signal amplifier performs amplification processing for subsequent accurate measurement and analysis, thereby reducing the measurement error and improving the measurement accuracy of the whole machine. The data acquisition system of the real-time monitoring module receives the electrical signal processed by the signal amplifier.

In addition, the iron-carbon voltage drop tester has a remote control test function module. By cooperating with the pneumatic clamp with automatic limit of the feeding module, all test items can be completed by one person, reducing the workload of front-line workers. A Bluetooth module is installed inside, which can provide a dedicated APP to perform all operations through mobile phones and tablets. The measured data is stored in real time in the local storage module. The iron-carbon voltage drop tester also has RS232, 485 or network transmission functions.

At this time, the staff can rotate the movable end of the rotating frame 202 to drive the docking rod 203 to fit together with the groove 2. At this time, the first docking block 206 is vertically aligned with the first docking groove 201, and the limiting screw 205 is rotated again to make the limiting screw 20 5 drives the first docking block 206 to move downward to dock with the first docking slot 201. The first docking slot 201 and the first docking block 206 match each other, so that the first docking block 206 limits the rotation of the movable end of the rotating frame 202 when it is inside the first docking slot 201, so that the rotating frame 202 and the power socket 103 are restricted together, so that the power socket 103 and the tester body 1 are strengthened to limit the position, so that when the iron-carbon voltage drop tester is operating, the power socket 103 is not easy to be separated from the power-on slot of the tester body 1, which can prevent the loss or incompleteness of the test data of the iron-carbon voltage drop tester, and is not easy to affect the accuracy of the test results of the iron-carbon voltage drop tester.

The cross-sectional size of the slide groove 3 is matched with the cross-sectional size of the slider 301, so that the slider 301 is not easy to shake inside the slide groove 3, and the fixed plate 303 drives the cleaning cloth 304 to stably wipe the display screen 102, so that the iron-carbon pressure drop tester is easy to clean the display screen 102.

[0027] In summary, the iron-carbon voltage drop tester can timely and conveniently grasp the detailed data after the electrode is assembled, and display the experimental current, resistance, and voltage drop data through the display screen 102, so as to judge the quality of the assembly, rotate the limit screw 205, and move the first docking block 206 downward to dock with the first docking groove 201, so that the rotating frame 202 and the power socket 103 are restricted together, and the power socket 103 and the tester body 1 are strengthened to limit the power socket 103. When the iron-carbon voltage drop tester is operating, the power socket 103 is not easy to be separated from the power-on slot of the tester body 1, which can prevent the loss or incompleteness of the test data of the iron-carbon voltage drop tester and is not easy to affect the accuracy of the test results of the iron-carbon voltage drop tester.
