Feeding arm swing arm control system of plate-shaped workpiece edge covering device

Abstract

A feeding arm swing arm control system of a plate-shaped workpiece edge covering device is composed of a comparison link feeding arm operation control link C alpha, a feeding arm swing angle control drive link Dr alpha, a feeding arm inversion trigger module G alpha, a feeding arm inversion execution module A alpha, a feeding arm rotary swing motor M alpha and a feeding arm swing angle signal processing module DT alpha. The given swing angle signal alpha R of the feeding arm is compared with the swing angle feedback signal alpha of the feeding arm in the middle to generate a corner deviation signal delta alpha of the feeding arm; through C alpha calculation processing, the delta alpha is converted into a feeding arm swing angle control signal alpha C; Dr alpha amplification is carrie out,the alpha C becomes a feeding arm operation driving signal alpha Dr, a PWM three-phase inverter bridge is triggered by the alpha Dr in the cascading link G alpha-A alpha of G alpha and A alpha, three-phase driving currents-i alpha A, i alpha B and i alpha C are output to a feeding arm rotary swing motor, and the currents drive M alpha and are converted to generate a feeding arm swing angle outputsignal alpha out; DT alpha detection and feedback is carried out, alpha out is introduced with alpha.

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...
