Main motor control system of plate-shaped workpiece edge covering device

Abstract

The invention discloses a main motor control system of a plate-shaped workpiece edge covering device. The main motor control system is composed of a comparison link, a main motor operation control link Cn, a main motor control system amplification link AM, a main motor MM and a main motor corner detection-feedback link Sn. The main motor given rotation angle signal nR is compared with the main motor rotation angle feedback signal n in a comparison link to generate a main motor rotation angle deviation signal delta n; the main motor rotation angle deviation signal delta n is converted into a main motor rotation angle control signal nC through calculation processing of a main motor operation control link Cn; in an amplification link AM of a main motor control system, a main motor corner control signal nC controls PWM output voltage, that is, a main motor operation driving signal eM represents driving voltage; the driving voltage of the eM drives the main motor MM to generate a main motorcorner output signal nout; through Sn detection and feedback in a main motor rotation angle detection-feedback link, a main motor rotation angle output signal nout is introduced into a comparison link in a 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...
