Main motor control system of plate-shaped workpiece hemming device

Abstract

A main motor control system of a plate-shaped workpiece hemming device, comprising a comparison link and a main motor operation control link C n , Main motor control system amplification link A M , main motor M M and main motor rotation angle detection-feedback link S n constitute. Main motor given rotation angle signal n R Compared with the main motor rotation angle feedback signal n in the comparison link, the main motor rotation angle deviation signal △n is generated; through the main motor operation control link C n Calculation and processing, the main motor rotation angle deviation signal △n is converted into the main motor rotation angle control signal n C ; In the amplification link A of the main motor control system M , the main motor angle control signal n C Control the PWM output voltage, that is, the main motor running drive signal e M Characterize the driving voltage; e M The driving voltage drives the main motor M M , to generate the main motor rotation angle output signal n out ; Through the main motor rotation angle detection-feedback link S n Detection, feedback, main motor rotation angle output signal n out The comparison link is introduced with the main motor rotation angle feedback signal n.

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...
