The fault classification of automatic winding machine is nothing more than: electrical, mechanical, transmission and pneumatic (if any), among which the electrical part is divided into strong and weak electricity. In the design, use and maintenance of CNC system, winding machine manufacturers usually consider giving alarm to vulnerable and fault-prone parts and giving alarm to them. After the circuit works, on the one hand, alarm information such as sound and light is given on the display screen or operation panel, on the other hand, protective instructions are issued to make the system power off or stop working, so as to ensure safety and prevent the expansion of the fault. Porter Automation Network mainly deals in all kinds of winding machines, pin inserting machines, riveting machines and so on, providing various kinds of automation products for China and Southeast Asia.

First, the whole machine reset method.

Generally speaking, the whole winding machine error caused by instantaneous fault can be eliminated by hardware reset or switching system power supply in turn. If the working memory area of the system is confused due to voltage instability and under-voltage caused by unplugging circuit boards or rectifier switching power supply, the system must be initialized and cleared. Before cleaning, attention should be paid to doing so. If the current data backup record can not be eliminated after reset initialization, hardware replacement diagnosis will be carried out.

Two. Compile trial run procedure.

The basis for determining the function of the whole machine system is to compile a reasonable program and run successfully. The incorrect setting of some parameters of winding and gluing may result in the failure of the system or the invalidation of a function. Sometimes the failure caused by the user's program error stops, so we can use the compilation of the trial run program to check and correct it. The user program is being erroneous to ensure its normal operation.

Three, make good use of adjustable components.

Adjustment of adjustable components such as winding tension, screen voltage and starting position of wire arrangement frame is a simple but effective method in maintenance. By adjusting the adjustable components, some harmless faults are corrected. For example, if an enterprise maintains a winding machine which has been used for many years, its system display screen is dark and normal after adjusting the power supply voltage of the screen.

Four. Spare parts replacement method

In the maintenance of winding machine, the parts suspected of failure are replaced by intact spare parts. After the maintenance personnel have basically judged the cause of the failure, this method can be used to diagnose the scope of the fault quickly, and make the winding machine put into normal operation quickly, and then return the damaged parts to repair. This is the commonly used troubleshooting method at present.

Five, improve environmental quality law

For some very strange faults, the reason can not be found by eliminating the replacement method. It often needs to start with the surrounding environment, which is generally divided into two kinds, power supply and space. Power supply improvement can use voltage stabilized isolation power supply to improve the fluctuation from power supply. For some high frequency interference from power supply, capacitive filter method can be used. Through these preventive measures to reduce the fault caused by 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, foundation floating, vibration, space radiation interference and so on, which need experienced maintenance technicians and professional equipment to detect and maintain.

Six, maintenance information tracking method

According to the actual work of the automatic winding and gluing machine and the previous fault records, it can be found that the accidental faults caused by the design or production process defects of the winding machine can be solved by constantly modifying and improving the system software or hardware. These modifications are provided to the maintenance personnel in the form of maintenance information. Through these customer feedback, the company can take this as the basis for troubleshooting, correct and thorough eradication of the fault, user reasonable feedback is also a strong force for our company to constantly improve.

In a word, the first step of repairing winding and gluing machine is to distinguish the real cause and location of the fault as soon as possible according to the fault phenomena. There are no strict boundaries in the actual application of these fault treatment methods. Sometimes only one method can eliminate the fault, and many methods may be needed at the same time. Its effect mainly depends on the experience of maintenance technicians and the depth of their understanding and mastery of the system principle and structure. This is not only the quality that maintenance personnel must possess, but also puts forward high requirements for maintenance personnel. It requires maintenance personnel of NC winding machine to be familiar with the structure and design idea of winding machine and the performance of NC winding machine. Only in this way can the cause of failure be quickly identified and the location of failure be judged. In addition, dimension In order to carry out on-site surveying and mapping of some circuits and parts during repair, senior maintenance personnel should also have the ability to draw engineering drawings.
