Automatic winding machine fault classification and solution

The fault classification of automatic winding machine is nothing more than: electrical, mechanical, transmission, pneumatic (if any), of which the electrical part is divided into strong and weak current, while the manufacturer of the winding machine generally considers giving alarm to vulnerable and fault prone parts in the design, use and maintenance of its NC system. After the alarm circuit works, on the one hand, it gives audible and visual alarm information on the display screen or operation panel, On the other hand, protective instructions are issued to cut off power or stop the system, so as to ensure safety and prevent the fault from expanding. Porter Automation Network is mainly engaged in various types of winding machines, pin inserting machines, riveting machines, etc., providing various automation products for China and Southeast Asia.

1、 Complete machine reset method

In general, the fault of the winding machine caused by the transient fault can be removed by hardware reset or switching the system power supply in turn. If the system working storage area is confused due to unstable voltage and undervoltage of the unplugged circuit board or rectifier switch power supply, the system must be initialized and cleared. Before clearing, the current data backup record should be made. If the fault cannot be eliminated after reset and initialization, Perform hardware replacement diagnosis.

2、 Preparation of commissioning procedure

Compiling a reasonable program and running it successfully is the basis to determine whether the system functions of the whole machine are in good condition. Some wrong winding parameters may cause system failures or some functions are invalid. Sometimes, the fault shutdown caused by user program errors can be checked by compiling a trial run program to correct user program errors to ensure its normal operation.

3、 Make good use of adjustable parts

For example, the adjustment of the winding tension, screen voltage, starting position of the cable truss and other adjustable parts is an easy but effective method in maintenance. By adjusting the adjustable parts, some harmless faults can be corrected. If a winding machine that has been used for many years is repaired in an enterprise, its system display screen is dark, and it is normal after adjusting the screen power supply voltage.

4、 Spare parts replacement method

During the maintenance of the winding machine, replace the parts suspected of failure with intact spare parts. After the maintenance personnel basically judge the cause of the failure, they can use this method to quickly diagnose the scope of the failure, and quickly put the winding machine into normal operation, and then return the damaged parts for repair. This is the common troubleshooting method used by Z at present.
