Industrial sewing machines are more and more widely used in today's clothing companies, but sometimes sewing machine defects can cause a headache for the company. Today's industrial sewing machine control systems usually have the function of intelligent and automatic defect inspection. We can determine what defects appear in the system according to different alarm codes of the system, and further determine which part has problems.
After determining the defective code, we can choose the corresponding treatment method to repair. Different brands of electronic control systems may use different defective codes, but the specific types of defects are not very different. In addition, the manual of the electronic control system is also marked with prominent and detailed notes.
At the same time, during the operation of the industrial sewing machine, the repair technician can carefully check the machine by vision, and then compare it with the normal operation of the system, and then reduce the defect plan or directly find the defective part. For example, check whether there are any scratches on the surface of the controller and the display screen, whether the plug is dropped, whether the lead is disconnected, whether the components of the circuit board are burnt, broken, or the pins are touching.
Sometimes the operator will replace the corresponding parts on the equipment with new parts to distinguish whether the parts are defective, defective parts or defective detailed components. When repairing, start with large parts and replace and clean step by step until defects are found. This method is mainly used when the accessories are satisfied or the electronic control system can communicate.
For example, when repairing the communication servo system, it is necessary to distinguish whether it is a system problem. Usually, the method of communicating with the normal control box is used to distinguish whether the defect is a problem with the industrial sewing machine machinery or the control box. This method is also used when repairing the circuit board, replacing the "suspected" defective components in the circuit with good components, querying the modification status of the controller, and distinguishing the address of the defect.
Sometimes the electromagnet function of the industrial sewing machine control system shows a defect alarm, and the power supply voltage of the electromagnet can be further disconnected by disconnecting the electromagnet connector to distinguish whether other circuits are defective. When the communication servo controller is working normally, the working voltage of each point in the machine indicates the working condition of the machine in the certain plan, and the working voltage must change when there is a defect. The voltage measurement method is to use a multimeter to check whether the operating voltage of each plug in the machine and each test point of the circuit board is too large or too small, and distinguish the specific defect factors according to the abnormal state of the voltage. When measuring, be careful to use different gears of the multimeter to measure AC voltage and DC voltage. The voltage measurement method is usually measured when the machine is live, so be careful about one-handed operation.
