Abstract

The invention relates to an automatic screw disassembling method and device based on visual positioning and torque control. The method includes the steps that a central controller controls an industrial camera through a network card, collects signals of a limiting sensor through a motion control card and controls four servo motor drivers, three motors are used for three axis position movement, and a fourth motor is used for driving a screwdriver to rotate. The industrial camera is carried by the three axis motors to move close to a target screw, a light source is turned on for photographing, the center position of the screw is recognized by adopting an image recognition method, two-dimensional coordinates of the center position are output, the three axis motors control the screwdriver to move to the center of the screw, the servo motor in a torque control mode controls the screwdriver to rotate, and the Z-axis motor synchronously cooperates to retreat so as to unscrew the screw. The automatic screw disassembling device is accurate in positioning, easy to operate, high in disassembling efficiency and capable of being used for automatically disassembling screws of various products.

Description

technical field [0001] The present invention relates to an automatic screw removal method and its device, in particular to an automatic screw removal method based on visual positioning and torque control, which is accurate in positioning, easy to operate, high in removal efficiency, and can be applied to automatic removal of screws of various products. its device. Background technique [0002] With the development of industries such as home appliances, a huge amount of electronic waste is faced with the problem of how to properly dispose of it. In the process of dismantling household appliances and electronic products, the disassembly of fixing screws is a key issue. At present, the dismantling industry of electronic waste components in my country mainly relies on manual disassembly. The outstanding problem of manual dismantling is low efficiency, and labor costs are increasing year by year. In addition, factors such as dust and noise in the dismantling process will cause ...
