At present, industrial robots have been widely used in the automotive and auto parts manufacturing, machining, electrical and electronics, rubber and plastics, food, wood and furniture industries. In industrial production, industrial robots such as welding robots, assembly robots, painting robots, and handling robots have been widely used. More and more robots are in the company, worrying about robots? How can I be prepared? How to simplify the solution? Let's hand you some tips and common troubleshooting. Don't panic when the robot fails during work. If the fault is not caused by the controller, the cause of the fault must be damage to the machine components. In order to handle the fault in the easiest way as soon as possible, the fault should be analyzed. And you need to find out which part is causing the fault. Please follow the steps below for simple inspection and maintenance: Step 1: Is there a problem with that axis? First, check which axis caused the fault. If it is difficult to detect the fault, check if there are any possible machine abnormalities. 1 Is there any part noise? 2 Is there any part overheating? 3 Is there any loose or recoiled parts? Step 2: Which part is damaged? If an abnormal axis is detected, which part is causing the problem. There are many possible reasons for the same phenomenon. note: 1) Overload - A phenomenon occurs when the load exceeds the rated motor load. Specifically, it is a thermal relay that triggers a coil protector. 2) There is noise during operation - the phenomenon is vibration during operation. 3) Swing when stopped - The phenomenon is that the swing occurs when the robot stops. 4) Irregular tremors - the phenomenon is that there is sporadic tremor when the robot is not moving. Step 3: After handling the failed part to investigate the failed part, perform the relevant repair steps according to “Main Component Troubleshooting and Resolutionâ€. Main component fault diagnosis and resolution The main components of industrial robots include reduction gears, brakes, motors, encoders, etc. In the failure of components, the reduction gears are often used as faults, followed by brakes, motors and encoders. When the reduction gear is damaged, it may vibrate or make an abnormal sound. In this case, it can cause overload and abnormal deviations to disturb normal operation. Sometimes it can cause overheating. The robot may not move at all or may have a position offset error. These causes may be caused by damage to the reduction gear spindle (S, H, V) or the wrist shaft (R2, B, R1). How to diagnose whether the spindle or the wrist shaft is damaged? A few careful diagnosis is required: (1) When the robot is working, check the reduction gear for vibration, abnormal sound or overheating. (2) Check the reduction gear for looseness and wear. Move the brake release switch of the S-axis to the [ON] position, swing the first arm in the front-rear direction, and check by hand whether it is abnormal. (3) Check if the peripheral device is connected to the robot before the abnormality occurs. (The damage of the reduction gear may be caused by the connection.) (4) Shake the end effector (such as welding torch and hand device, etc.) back and forth to check if the reduction gear is loose. (5) Turn off the motor and turn on the brake release switch to check if the shaft can be rotated by hand. If not, it shows that the reduction gear is not in good condition. (6) Check if the peripheral device has been connected to the robot before the abnormality occurs. (The damage of the reduction gear may be caused by the connection.) After the diagnosis according to this step, it can be determined whether the spindle or the wrist shaft is damaged. After the damage position is determined, a corresponding solution is made for it. If the main shaft needs to replace the reduction gear, a crane is needed to lift and suspend the robot arm. In addition to replacing the reduction gear, the wrist shaft can also replace the entire mechanical wrist part. It is a quick and reliable solution to replace the mechanical wrist part of the whole machine, because it takes time and some necessary equipment to replace the reduction gear. Please consult our service department if you have any difficulties. Compared to the replacement of the reduction gear, the replacement of the brake device and the motor is much simpler. It is worth noting that safety is required when diagnosing and replacing the brake device. When the motor is turned off, check whether the brake sound can be heard during operation by turning the brake release switch on and off. If you can't hear it, the brake line is broken. When the brake release switch is turned on and off, be careful that the arm is released. The brake release switch is located on the control panel of the controller door. Check for new parts in time for damage and aging.
