Analysis of fault detection method of industrial sewing machine system

Industrial sewing machines are more and more widely used in clothing enterprises now, but sometimes the sewing machine will cause a headache after the failure of the sewing machine. Today, Wuxi will give you a summary of some methods for fault detection of industrial sewing machines, hoping to help you. Maintenance technicians can carefully observe the machine with vision, and then compare it with the normal operation of the system, so as to narrow down the fault scope or directly find the fault location.

Today's industrial sewing machine control systems generally have the function of intelligent automatic fault detection. We can determine what fault has occurred in the system according to the different alarm codes of the system, and further determine which part has the problem. After determining the fault code, we can use the corresponding processing method to repair. Different brands of electronic control systems may use different fault codes, but the specific types of faults are not very different. In addition, the manual of the electronic control system is also marked with obvious and specific notes.

Therefore, if you get the electric control, the manual of the sewing machine can't be thrown around casually, and it can come in handy when it can be repaired later.

At the same time, during the operation of the industrial sewing machine, maintenance technicians can carefully observe the machine with vision, and then compare it with the situation when the system is working normally, so as to narrow down the fault range or directly find the fault location. For example: observe whether there is a short jumper, whether there are any scars on the surface of the controller and the display screen, whether the plug is falling off, whether the lead is disconnected, whether the components of the circuit board are burnt, broken, or the pins collide. situation, solve it in different ways.

Sometimes the operator will replace the corresponding parts on the equipment with new parts to determine whether the parts are faulty, the fault location or the specific components of the fault. When repairing, start with large parts and replace them step by step until the fault is found. This method is mainly used when the accessories are sufficient or there is an intact electronic control system that can be replaced.

For example, when repairing the AC servo system, it is necessary to first judge whether it is a system problem. Generally, the method of replacing the normal control box is adopted to judge whether the fault is the problem of the industrial sewing machine machinery or the control box. This method is also used when repairing the circuit board, replacing the circuit with good components.“Suspected”Fault components, observe the changes of the controller, and determine the fault location.

Sometimes the electromagnet function of the industrial sewing machine control system has a fault alarm. It can be judged whether other circuits are faulty by disconnecting the electromagnet connector or further disconnecting the power supply voltage of the electromagnet.

When the AC servo controller is working normally, the working voltage of each point in the machine represents the working condition of the machine within a certain range, and the working voltage will inevitably change when a fault occurs. The voltage measurement method is to use a multimeter to detect whether the working voltage of each plug in the machine and each test point of the circuit board is too large or too small, and determine the specific cause of the fault according to the abnormal voltage. When measuring, pay attention to measuring AC voltage and DC voltage with different gears of the multimeter.

The measuring voltage method is usually measured when the machine is charged, so pay attention to one-handed operation.
