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...

Problems solved by technology

[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
