Trouser-type sanitary napkin equipment common fault inspection method

During the fault detection process of the pant-type sanitary napkin equipment, it is allowed to use the self-diagnosis function of the machine system to make judgments, and at the same time, some common methods of fault inspection should be used flexibly. In summary, there are many inspection methods for the mechanical failure of trousers sanitary napkins. Here are some commonly used methods.

1. Intuitive method of pant-type sanitary napkin equipment

The intuitive method follows the principle of "outside first, then inside". The fault diagnosis is made by looking, listening, smelling, asking, touching and other methods, checking from the outside to the inside one by one, which can narrow the fault range to a module or a printed circuit board. This requires maintenance personnel to have rich practical experience, a wide range of knowledge and comprehensive judgment ability in multiple disciplines. For example, the trousers-type sanitary napkin equipment suddenly stopped during the processing. The inspection found that the main circuit fuse of the Y-axis motor was blown. After inspection, it was a component related to the Y-axis. It was found that the power line of the Y-axis motor was frayed in some places on the bed, causing a short circuit. After replacing the power line, the fault was eliminated and the equipment returned to normal.

2. Self-diagnostic function method of pant-type sanitary napkin equipment

Although the modern trouser-type sanitary napkin equipment system has not yet reached a high level of intelligence, it already has a strong self-diagnosis function. It can monitor the working status of the hardware and software of the machine system at any time. Once an abnormality is found, an alarm message will be displayed on the CRT immediately or the approximate cause of the failure will be indicated with a light-emitting diode. Using the self-diagnosis function, it can also display the state of the interface signal between the system and the host, so as to determine whether the fault occurs in the mechanical part or the machine system part, and indicate the approximate location of the fault. This method is an effective method for current maintenance work.

3. Functional procedure test method for pant-type sanitary napkin equipment

The so-called functional program testing method is to compile the common functions and special functions of the trousers sanitary napkin equipment system, such as linear positioning, circular interpolation, spiral cutting, canned cycle, user macro programs, etc., into a manual programming or automatic programming method. The functional program tests the tape, sends it into the machine system through the tape reader, and then starts the machine system to run, so as to check the accuracy and reliability of the equipment to perform these functions, and then determine the possible cause of the failure. This method is a better method for judging if it is difficult to determine whether it is a programming measure, an operation error, or an equipment failure when the inspection of long-term idle machinery and equipment when the machine is turned on and the equipment processing results in waste but no alarm.

4. Replacement method of pant-type sanitary napkin equipment

The replacement method of pant-type sanitary napkin equipment is a simple and easy method, and it is also one of the commonly used methods for on-site judgment. The so-called replacement method is to use spare printed circuit boards, templates, integrated circuit chips or components to replace the suspicious parts under the condition of analyzing the general cause of the failure, thereby reducing the scope of the failure to the printed circuit or chip level. In fact, it is also verifying the correctness of the analysis, but before the replacement of the spare board, it should be carefully checked whether the spare board is in good condition, and it should be checked that the state of the spare board should be exactly the same as that of the original board. This includes checking the selector switch on the board, the set position of the shorting bar, and the position of the potentiometer.

5. Parameter inspection method of pant-type sanitary napkin equipment

As we all know, the parameters of pant-type sanitary napkin equipment can directly affect the performance of the machine equipment. The parameters are usually stored in the magnetic bubble memory or in the CMOS RAM that needs to be kept by the battery. Once the battery is insufficient or due to external interference and other factors, the individual parameters will be lost or changed, causing confusion and making the device unable to work normally. At this time, the fault can be eliminated by proofreading and correcting the parameters. When the equipment has been idle for a long time and reworked for no reason, there is an abnormal phenomenon or a fault without an alarm, and the relevant parameters should be checked and calibrated according to the fault characteristics.

In addition, after long-term operation, the related parameters of the trousers sanitary napkin equipment need to be adjusted due to the wear of its mechanical transmission parts and the performance change of the electrical components; the failure of some equipment is often caused by the failure to modify some unsuitable parameters in time. caused. Of course, these faults belong to the category of soft faults.
