Abstract

Abstract

Automatic screw tightening machine is a machine in modern industry
that improves workers’ work efficiency and is widely used in many fields. Automatic screw tightening machine is an auxiliary equipment for many large devices, which can greatly reduce the labor intensity of workers. At present, the structure of automatic screw tightening machines is complex, with high technological content and difficulty in localization. The automatic screw tightening control realizes fully automatic control of the screw tightening process, and can accurately control a series of actions such as separating, transferring, and tightening screws according to the pre programmed program by the operator. The controller can perform comprehensive detection of the power supply, including displaying parameters such as voltage, frequency, power factor, output current, and automatically compensating for them. At the same time, the controller can be equipped with automatic step-by-step compensation function. When a hole is not screwed, the machine automatically re sends the screw through detection to ensure the quality of the workpiece. And it also achieves the purpose of using screws of different sizes.
