What are the maintenance methods for winding machine failures?

The fault classification of winding machines is nothing more than: electrical, mechanical, transmission, and pneumatic (if any). The electrical part is divided into strong and weak electricity. The manufacturers of winding machines generally consider giving alarms to vulnerable and faulty parts in the design, use and maintenance of their CNC systems. After the alarm circuit works, on the one hand, it gives sound, light and other alarm information on the display screen or operation panel, and on the other hand, it issues protective instructions. The system is powered off or stopped to ensure safety and prevent the expansion of faults.

1. Whole machine reset method

Under normal circumstances, the whole machine error caused by instantaneous faults of winding machines can be cleared by hardware reset or switching system power in turn. If the system working storage area is confused due to unstable voltage, plugging and unplugging circuit boards or rectifier switch power supply undervoltage, the system must be initialized and cleared. Before clearing, you should pay attention to making a backup record of the current data. If the fault cannot be eliminated after reset and initialization, perform hardware replacement diagnosis.

2. Prepare a trial run program

Preparing a reasonable program and running it successfully is the basis for determining whether the whole system functions well or not. Some winding parameter setting errors may cause system failure or invalid functions. Sometimes the machine stops due to faults caused by user program errors. For this, you can use the preparation of a trial run program to check and correct the user program errors to ensure its normal operation.

3. Make good use of various adjustable components

Adjustment of adjustable components such as winding tension, screen voltage, and wire rack starting position is an easy but effective method in maintenance. By adjusting the adjustable components, some harmless faults can be corrected. For example, when a winding machine that has been used for many years was repaired in a certain enterprise, the screen of its system was dim, and it was normal after adjusting the screen power supply voltage.

4. Spare parts replacement method

In the maintenance of the winding machine, the suspected faulty parts are replaced with intact spare parts. After the maintenance personnel basically determine the cause of the fault, this method can be used to quickly diagnose the fault range and put the winding machine into normal operation quickly, and then return the broken parts for repair. This is the most commonly used troubleshooting method.

5. Improvement of environmental quality method

For some very strange faults, the cause cannot be found by the elimination and replacement method. It is often necessary to start from the surrounding environment. The environment is generally divided into two types, power supply and space. Power supply improvement can use a voltage-stabilized isolated power supply to improve the fluctuation from the power supply. For some high-frequency interference from the power supply, the capacitor filtering method can be used. Through these preventive measures to reduce the faults caused by the power supply, it is also necessary to increase and check whether the grounding is good. There are many reasons for space interference, such as dust, gas, floating and vibration of the foundation, space radiation interference, etc., which require experienced maintenance technicians and professional equipment to detect and maintain.

6. Maintenance information tracking method

According to the actual work of the winding machine and previous fault records, accidental faults caused by defects in the design or production process of the winding machine can be found, which can be solved by continuously modifying and improving the system software or hardware. These modifications are continuously provided to maintenance personnel in the form of maintenance information. Through these customer feedback, the company can use this as the basis for troubleshooting to correctly and thoroughly eradicate the fault. Reasonable feedback from users is also a powerful boost for our company's continuous improvement.

In short, the first step of winding machine maintenance is to identify the real cause and fault location as soon as possible according to the fault phenomenon. There is no strict boundary in the actual application of these fault handling methods. Sometimes only one method can eliminate the fault, or multiple methods may be required at the same time. Its effect mainly depends on the experience of the maintenance technician and the depth of his understanding and mastery of the system principles and structures. This is not only a quality that maintenance personnel must possess, but also puts forward high requirements for maintenance personnel. It requires CNC winding machine maintenance personnel to be familiar with the structure and design ideas of the winding machine, and familiar with the performance of the CNC winding machine. Only in this way can the cause of the fault be quickly found and the fault location be determined. In addition, in order to conduct on-site mapping of certain circuits and parts during maintenance, as a senior maintenance personnel, they should also have a certain ability to draw engineering drawings.
