Loading Arm Swing Arm Control System of Plate-shaped Workpiece Hemming Device

Abstract

A feeding arm swing arm control system of a plate-shaped workpiece hemming device, which is composed of the comparison link loading arm operation control link C α , Loading arm swing angle control drive link Dr α , Loading arm inverter trigger module G α , Loading arm inverter execution module A α , Loading arm swing motor M α And loading arm swing angle signal processing module DT α constitute. The given swing angle signal α of the loading arm R Compared with the feedback signal α of the swing angle of the loading arm, a deviation signal △α of the rotation angle of the loading arm is generated; through C α Calculation and processing, △α is converted into the control signal α of the swing angle of the loading arm C ; via Dr. α Zoom in, alpha C Become the driving signal α of loading arm operation Dr , at G α 、A α The cascade link G α -A α , α Dr Trigger the PWM three-phase inverter bridge, and output the three-phase drive current to the swing motor of the upper material arm——i αA i αB and i αC , this current drives M α , the conversion produces the output signal α of the swing angle of the loading arm out ; by DT α detection, feedback, alpha out 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...
