1. Improve environmental quality law
For some very strange faults, using the exclusion method can not find the reasons, often need to start from the surrounding environment, the environment is generally divided into two types, power and space. The power supply can be improved by using a regulated isolated power supply to improve the fluctuations from the power supply. For some high-frequency interference from the power supply, capacitive filtering can be used. Through these preventive measures, the failure caused by the power supply can be reduced, and the grounding can be increased and checked. It is also very necessary. There are many reasons for space interference, such as dust and gas, virtual floating and vibration of the foundation, and space radiation interference. There are a lot of things that need to be tested and maintained by experienced service technicians and professional equipment.
2. Maintenance information tracking method
According to the actual work of the winding machine and past fault records, it can be found that the accidental fault caused by the winding machine design or production process defects can be solved by continuously modifying and improving the system software or hardware. These changes are continuously provided to our maintenance personnel in the form of maintenance information. Through these customer feedbacks, the company can use this as the basis for troubleshooting, correctly and thoroughly eradicate the failure, and the user’s reasonable feedback is also a powerful boost to our company’s continuous improvement. The
3. Make good use of adjustable parts
Such adjustments as the tension of the winding machine, the screen voltage, the start position of the cable rack, and other adjustable components are a simple but effective method in maintenance. Through the adjustment of adjustable parts, some innocuous faults are corrected. For example, in a certain enterprise, repairing a winding machine that has been used for many years, its system display screen is dark, and it is normal after adjusting the screen power supply voltage.
4. Replacement of spare parts
In the maintenance of the winding machine, replacing the parts that are suspected to be faulty with the spare parts that have been completed, and the maintenance personnel can basically determine the cause of the fault, this method can be used to quickly diagnose the fault range and quickly put the winding machine into normal operation, and then it will be bad. Parts return to repair, which is currently the most commonly used troubleshooting method.
In short, the first step of winding machine maintenance is to identify the real cause of the fault and the location of the fault as soon as possible according to the fault phenomenon. There is no strict limit to the actual fault handling of these fault handling methods, and sometimes only one method can be used. Failures may also require multiple methods to be performed at the same time. The effect depends mainly on the experience of the maintenance technician and the depth of understanding and mastery of the system principle and structure. This point is not only the quality that the maintenance personnel must have, but also puts high requirements on the maintenance personnel. It requires the maintenance staff of the NC winding machine to be familiar with the structure and design concept of the winding machine and be familiar with the performance of the NC winding machine. In this way, it is possible to quickly find the cause of the fault and determine the location of the fault. In addition, in order to perform on-site mapping of certain circuits and parts during maintenance, the senior maintenance personnel should also have the ability to draw engineering drawings.
