The application of welding positioner is more and more, with its convenient operation and powerful function. However, most of the operators are not professionals, so there are often problems. The following positioner gives you a detailed explanation of the electrical fault of welding positioner.
Inspection steps of welding positioner failure
Step 1: the operator of the welding positioner is required to keep the fault status on site as much as possible without any treatment, so as to analyze the cause of the fault. At the same time, the operator is required to carefully inquire about the fault indication and the occurrence of the fault, carefully investigate various situations, and make preliminary judgment according to the site situation and description.
Step 2: analyze the fault type of the welding positioner, so as to determine the principle of troubleshooting. Refer to the operation manual and diagnosis manual, and list all causes of the fault.
Step 3: find out the cause of the fault according to the listed reasons, which may need to be tested many times, which requires the technical personnel to have a good technical level and experience.
Common electrical fault diagnosis methods of welding positioner
Method 1: intuitive method
It is to use the senses to carry out inspection, follow the principle of "first outside, then inside", and use the methods of looking, smelling, asking, touching, etc. to narrow the scope to a module or a circuit board of the welding positioner. Therefore, the requirements for the maintenance personnel are very high, and they should have rich knowledge and experience.
Method 2: interface state inspection
Now, PLC control is widely used, and the communication between CNC and PLC is in the form of a series of interface signals. This inspection method requires maintenance personnel to be familiar with both interface signals and PLC programmers.
Method 3: parameter adjustment
This method needs to readjust one or more relevant parameters to eliminate one by one, so the maintenance personnel of welding positioner are required to be very high, not only familiar with system parameters and parameter address, but also have rich experience in electrical debugging.
Method 4: exchange method
It is a simple and easy method, but before use, we should pay attention to some matters, such as whether the required components are in good condition, whether the state is consistent, etc., so we should consider carefully in advance, design a good software and hardware exchange scheme, and confirm that it is accurate, otherwise it will cause confusion of thinking, and may cause new faults.
When you are operating the welding positioner and some of the above electrical faults occur, you can deal with them according to the above inspection steps and diagnosis methods. The earlier you deal with them, the earlier you can work and ensure the work efficiency.
