| ●Fault phenomenon When theuVK-1 Auto-turret Micro Vickers and Knoop Hardness Tester is powered on, the device interface stays on the startup screen and no subsequent operations can be performed, such as the selection of hardness test process, parameter setting and sample measurement. This seriously affects the normal use of the equipment and hinders the development of related testing work. ●Processing process 1. Preliminary judgment of the fault location: After receiving the user's feedback on the abnormal startup problem, the technician first guides the user to open the upper cover of the hardness tester to check whether the loading motor shows signs of rotation at the moment of startup. The loading motor is the key execution component of the hardness tester to realize the loading operation. Whether it can operate normally has an important indicative role in judging the fault location. If the loading motor can rotate normally, it means that the fault may occur in other parts such as the control system or display system; if the loading motor has no response, it means that the fault is likely to be related to the motor drive or related power supply circuit. 2. Check the connection of the driver box wires: If the initial inspection finds that the loading motor has no response, the technician will further guide the user to open the back panel of the hardness tester and conduct a detailed inspection of the connection of the driver box wires. The driver box is the core component that provides the driving signal and power supply for the loading motor. The stability of its wire connection is directly related to whether the motor can work normally. The technician requires the user to carefully check whether the wire connectors are loose, detached or oxidized, and ensure that each wire connecting the driver box to the motor and other related components is in a good connection state. 3. Check the connection of the mainboard wires: After checking that there is no abnormality in the connection of the driver box wires, considering that the internal components of the equipment may have poor contact due to vibration during transportation, the technician recommends that the user carefully turn over the mainboard and comprehensively check the connection of the wires on the mainboard. As the core control unit of thehardness tester, the mainboard is connected to many sensors, controllers and other functional modules. Any loose connection of the wires may cause equipment failure. The technician guides the user to carefully check whether the wires at each interface on the mainboard are tightly inserted and whether there is any virtual connection to ensure that the electrical connection between the mainboard and various components is stable and reliable. ●After the user carefully checked according to the above steps, it was found that the reason why the hardness tester could not start normally after turning on was that the wire connector fell off. The fallen wire connector is responsible for connecting the mainboard with a key functional module, which makes the module unable to communicate normally with the mainboard, which in turn causes the device to fail to complete the initialization process during the startup process, and finally stays on the startup interface and cannot be operated. ●Summary During this troubleshooting process, by adopting a step-by-step troubleshooting method, starting from the operation of the loading motor, the drive box wire connection and the mainboard wire connection were checked in turn, and finally the cause of the fault was successfully determined to be the wire connector falling off. During the entire processing process, clear and organized inspection steps were provided to users, which effectively helped users quickly locate the problem, saved troubleshooting time, and reduced the impact on users' normal detection work. In order to avoid similar failures from happening again in the future, it is recommended that relevant personnel strengthen the inspection of the internal line connection and other parts of the equipment before and after the equipment is transported and before each use. Tighten all wire connectors to ensure that they are firmly connected, and check whether the wires are damaged or aged. If there are any problems, replace them in time. Through these preventive measures, the probability of equipment failure caused by line connection problems can be effectively reduced, the normal operation of the hardness tester can be ensured, the stability and reliability of the equipment can be improved, and a strong guarantee can be provided for the user's testing work. |
