The fault classification of the winding machine is nothing more than: electrical, mechanical, transmission, pneumatic (if any), in which the electrical part is divided into strong and weak, and the manufacturer of the winding machine is generally in its numerical control system. In the design, use and maintenance, it is considered to give an alarm to the vulnerable and faulty parts. After the alarm circuit works, on the one hand, the sound and light alarm information is given on the display or the operation panel, and on the other hand, the protective instruction is issued. Power down or stop the system to ensure safety and prevent failures from expanding.

Machine reset method

Under normal circumstances, the winding machine can be cleared by the hardware reset or the switching system power supply due to the whole machine error caused by the transient fault. If the system working storage area is unstable due to voltage instability, the plug-in circuit board or the rectifier switch power supply undervoltage causes confusion. , the system must be initialized and cleared. Before cleaning, you should pay attention to the current data backup record. If the fault cannot be eliminated after reset initialization, perform hardware replacement diagnosis.

Preparation of test run procedures

Compiling a reasonable program and running successfully is the basis for determining whether the system function is intact or not. Some winding parameter setting errors may cause system failure or a certain function to be invalid, sometimes due to user program error caused by downtime. You can use the test run program to check and correct the error of the user program to ensure its normal operation.

Make good use of adjustable parts

Such as the tension of the winding, the screen voltage, the adjustment of the starting position of the cable tray, etc., is an easy and simple method in maintenance. Correct some innocuous faults by adjusting the adjustable parts. For example, if a winding machine that has been used for many years is repaired in a certain enterprise, the system display screen is dim, and it is normal after adjusting the screen power supply voltage.

Spare replacement method

In the maintenance of the winding machine, replace the suspected faulty parts with the used spare parts. After the maintenance personnel basically judge the cause of the fault, this method can be used to quickly diagnose the fault range and make the winding machine quickly put into normal operation, and then the bad ones will be broken. Parts are returned for repair, which is currently the most common troubleshooting method.

Environmental Quality Improvement Act

For some very strange faults, the exclusion method can not find the reason, 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 power supply to improve the fluctuations from the power supply. For some high-frequency interference from the power supply, capacitor filtering can be used. These preventive measures are used to reduce the fault caused by the power supply, increase and check whether the grounding is good. It is also very necessary.

There are many reasons for space disturbances, such as dust, gas, grounding, vibration, space radiation interference, etc., which require experienced maintenance technicians and professional equipment to detect and maintain.

Maintenance information tracking method

According to the actual work of the winding machine and the previous fault record, it can be found that the accidental failure caused by the design of the winding machine or the defects of the production process can be solved by continuously modifying and perfecting the system software or hardware. These modifications are continuously provided to the service personnel in the form of maintenance information.

Through these customer feedback, the company can use this as the basis for troubleshooting, correctly and thoroughly eradicate the fault, and the reasonable feedback from the user is also a powerful boost for our company.

In short, the first step of the repair of the winding machine is to determine the real cause and the fault location of the fault as soon as possible according to the fault phenomenon. These fault handling methods have no strict limits in practical use, and sometimes can be eliminated by only one method. Failures may also require multiple methods to be performed simultaneously.

The effect depends mainly on the experience of the service technician and the depth of understanding and mastery of the system principle and structure. This is not only the quality that maintenance personnel must possess, but at the same time it puts high demands on the maintenance personnel. It requires the CNC winding machine maintenance personnel to be familiar with the structure and design idea of the winding machine and familiar with the performance of the CNC winding machine. In this way, it is possible to quickly find out the cause of the fault and determine the location of the fault. In addition, in order to carry out on-site surveying of certain circuits and parts during maintenance, as a senior maintenance personnel, it is also necessary to have the ability to draw engineering drawings.
