Automatic brushless BLDC motor stator coil winding machine maintenance basic method

Automatic winding machine fault classification is no more than: electrical, mechanical, transmission, pneumatic (if any) of these, the electrical part is divided into strong, weak electricity, and winding machine manufacturers generally in the design, use and maintenance of its CNC system, there are considered vulnerable, easy to failure parts to give the alarm, alarm circuit work, on the one hand, in the display or operation panel to give sound, light and other alarm information, on the other hand Send out protective instructions. Vacuz produces all kinds of winding machines, testing machines, wire handling machines, etc., and provides all kinds of automation products for the world.

I. Whole machine reset method

General circumstances of the winding machine due to transient failure caused by the whole machine error, available hardware reset or switch the system power supply in turn to clear the fault, if the system work storage area due to voltage instability, unplugged circuit board or rectifier switch power supply undervoltage caused by confusion, the system must be initialized and cleared, cleared before the current data backup records should be noted, if the fault can not be eliminated after the initialization of the reset, the hardware If the fault can not be eliminated after the reset and initialization, then the hardware replacement diagnosis.

Second, the preparation of trial run program method

The preparation of a reasonable program and run successfully is the basis for determining the integrity of the entire system function, some winding parameters set wrong may cause system failure or a function is invalid, sometimes due to user program errors caused by the failure of the shutdown, which can be used to prepare a trial run program to check and correct the user program errors to ensure its normal operation.

Third, make good use of the adjustable components

Such as winding tension, screen voltage, the starting position of the line frame and other adjustable components of the adjustment, in the maintenance is an easy to simple but effective way. Through the adjustment of adjustable components, correct some harmless failure. Such as in an enterprise repair a winding machine used for many years, the system display screen obscure, by adjusting the screen power supply voltage after normal.

Fourth, spare parts replacement method

In the maintenance of the winding machine, with intact spare parts to replace the suspected failure of the components, the maintenance staff basic judgment of the cause of the failure, the use of this method to quickly diagnose the scope of the fault, and the winding machine quickly into normal operation, and then the bad parts back to repair, which is currently the most commonly used troubleshooting methods.

Five, improve the quality of the environment method

For some very strange failure, with the exclusion of replacement method can not find the cause, often need to start from the surrounding environment, the environment is generally divided into two kinds, power supply and space. Power supply to improve the use of regulated isolated power supply, to improve the fluctuations from the power supply, for some high-frequency interference from the power supply can be used capacitive filtering method, through these preventive measures to reduce the failure caused by the power supply, increase and check whether the grounding is good is also necessary. There are many causes of space interference, dust, gas, etc., the foundation of the virtual floating, vibration, etc., space radiation interference, etc., to name a few, need experienced maintenance technicians and professional equipment to detect and maintain.

Sixth, maintenance information tracking method

According to the actual work of the automatic winding machine and past failure records, occasional failures 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 Vacuz maintenance personnel in the form of maintenance information. Through these customer feedbacks, our company can use this as the basis for troubleshooting and correctly and thoroughly eradicate the faults. Reasonable feedback from users is also a powerful help for our company to keep improving.

In short, the first step of winding machine repair is to identify the real cause of the fault and the fault area as soon as possible according to the fault phenomenon, these fault handling methods, the actual use of no strict boundaries, sometimes only one method to remove the fault, may also require a variety of methods at the same time. The effect depends mainly on the experience of the maintenance technician and the depth of his understanding and mastery of the principles and structure of the system. This is both the quality of maintenance personnel must have, but at the same time put forward high requirements for maintenance personnel, it requires CNC winding machine maintenance personnel familiar with the structure of the winding machine and design ideas, familiar with the performance of CNC winding machine, only in this way, in order to quickly identify the cause of the fault, determine the location of the fault, in addition, maintenance in order to certain circuits and parts for on-site mapping, as senior maintenance personnel should also Have the ability to draw engineering drawings.
