Control system of unloading arm and swing arm of plate-shaped workpiece hemming device

Abstract

A blanking arm swing arm control system of a plate-shaped workpiece hemming device, which is controlled by the comparison link of the blanking arm operation control link C β , The swing angle control drive link Dr of the unloading arm β , Loading arm inverter trigger module G β , Loading arm inverter execution module A β , Unloading arm swing motor M β And the swing angle signal processing module DT of the feeding arm β constitute. Feed arm given swing angle signal β R Compared with the feedback signal β of the swing angle of the blanking arm, a deviation signal Δβ of the swing angle of the blanking arm is generated; through C β Calculation processing, Δβ is converted into the swing angle control signal of the feeding arm β C ; via Dr. β Amplify, beta C Become the driving signal β of the feeding arm operation Dr , at G β 、A β The cascade link G β -A β , β Dr Trigger the PWM three-phase inverter bridge, and output the three-phase drive current to the swing motor of the lower material arm——i βA i βB and i βC , this current drives M β , converted into the output signal β of the swing angle of the feeding arm out ; by DT β detection, feedback, beta out Introduced with β

Description

technical field [0001] The invention relates to a method for wrapping the side of a flat workpiece. Background technique [0002] In many production lines of flat-shaped products, there is a process of side-wrapping flat-shaped workpieces, especially for circuit board manufacturers. This type of production process is: wrapping the entire periphery of the flat-shaped workpiece with a special adhesive tape. At present, this kind of process is all done manually, and the result is that the consistency of the wrapping state is poor, and there are defects such as partial sticking, folds, and leaks in different parts. For the usual large and heavy boards, manual operation is more difficult. This is a bottleneck that seriously affects the process of related product production lines, hindering the automation of the entire production process. Therefore, it is urgent to develop an automatic method that can ensure the consistency of the wrapping state and replace the heavy manual ope...
