[0007] The traditional balance crane air pressure control device has many pneumatic components and parameters that need to be adjusted according to the change of the load. The system is complex, and the matching of each adjustment parameter is difficult. The handling of a single selected workpiece is more difficult for workpieces with variable loads in assembly; the range of adjustment value of the pressure regulating valve is large, the force arm changes during the movement of the four-bar mechanism, and the balance crane needs to be continuously established during work. The balance state is unstable, and the working stability and precision of the balance crane are poor

Abstract
The invention relates to an adaptive pressure balance control system based on a microcontroller, which comprises an air intake, an air exhaust opening, a cylinder, a pneumatic control safety valve, an air pressure transmission loop and a control circuit. The air pressure transmission loop comprises a pressure-regulating valve, an air inlet solenoid valve, an exhaust solenoid valve and a pressure sensor, one end of the air inlet solenoid valve is connected to the air intake through the pressure-regulating valve, the other end is connected to the exhaust solenoid valve, the other end of the exhaust solenoid valve is connected to the air exhaust opening, the pressure transducer is connected between the air inlet solenoid valve and the exhaust solenoid valve; the control circuit comprises an elevating switch, the microcontroller, a drive circuit and a relay, the input end of the microcontroller is connected to the elevating switch and the pressure transducer, the output end is connected to the drive circuit, and drive circuit is connected to the air inlet solenoid valve and the exhaust solenoid valve through the relay. The adaptive pressure balance control system has the beneficial effect that the air passage is simple and reliable, volume is small, weight is light, integrated level is high, application scope is large, operation is simple and flexible, load change is not required for adjusting, and production efficiency of a production line is increased.
Description
technical field [0001] The invention relates to a pressure adaptive balance control system, in particular to a microcontroller-based adaptive pressure balance control system. Background technique [0002] The adaptive pressure balance system is widely used, and is mostly used in handling and assembly, where the product load is variable and the operation needs to be flexible, precise and efficient. It ingeniously applies the principle of force balance to make the workpiece form a gravity-free floating state in the air, that is, the gravity of the workpiece is balanced by the corresponding pulling force, so that the operator only needs a small operating force when carrying out the operation of the workpiece . For the operator, without skilled jog key operation, the heavy object can be pushed and pulled by hand, and the heavy object can be placed in any position in the space correctly, and the maximum load can reach 880Kg. [0003] The microcontroller-based self-adaptive pres...
