Fault detection method for Automatic screw locking machine

Although the automatic screw machine is easy to use, but if it is not used properly, it is easy to have some problems, such as: power supply, air source, hydraulic source and other problems often lead to the failure of automation equipment. For example, power supply problems, including all workshop power supply problems, such as low power supply, safe combustion, poor power plug contact, etc.Air pump or hydraulic pump is not open, air blowing three or two parts are not open, discharge valve or some pressure valve in the hydraulic system is not open, the fault detection of automatic screw tightening machine should include the following aspects:

Power and air supply：the most basic needs of automatic screw tightening machine, including the power supply of each equipment and the power supply of the workshop. The air source includes the air source pressure required by the air blowing equipment. Hydraulic sources, including the working state of the hydraulic pump, are used for automation equipment and hydraulic equipment.

Whether the direction of the sensor is offset: automatic screw machine has more safety and detection sensors, due to the negligence of equipment maintenance personnel, resulting in sensor positioning errors, such as not in place, sensor fault, sensitivity fault, etc, Frequently observe the induction direction and sensitivity of the automatic screw machine sensor, find errors and adjust them in time. If the sensor of automatic screw tightening machine is broken, replace it immediately.

Relay, flow control valve, pressure control valve: automatic screw machine relay and magnetic induction sensor is the same, long-term use will appear the iron core bonding situation, and then can't guarantee the normal circuit, need to be replaced. In a blow or hydraulic system, the opening of the throttle valve and the pressure regulating spring of the pressure valve will loosen or slide with the movement of the equipment.

Dry Electrical, air blow and Hydraulic circuit connections: if none of the above three step shows any doubt, then look at all cycles, check whether the wire in the line is broken, especially if the wire in the slot is broken by the slot, check whether the air pipe is damaged, and see if the hydraulic pipe is blocked. If the trachea is severely creased, replace it immediately.
