Discharging rod telescopic control system of plate-shaped workpiece edge wrapping device

Abstract

A discharging rod telescopic control system of a plate-shaped workpiece edge wrapping device is composed of upper-lower comparison links, a discharging rod running control link CdB, a discharging rodrunning control system upper contraction amplification link APTB, a discharging rod running control system lower stretching amplification link ANTB, a discharging rod telescopic motor stator winding LTB, a discharging rod upper contraction in-place magnetic sensitive resistor RMTB, a discharging rod upper contraction in-place signal optocoupler LCTB and a discharging rod contact press signal detection link DTSB. Discharging rod given upper contraction displacement signals dBR are compared with discharging rod upper contraction in-place signals sTB, and discharging rod upper contraction displacement deviation signals delta dTB are generated; through CdB, delta dTB becomes discharging rod upper contraction displacement control signals dPBC to control ePB to drive the discharging rod telescopic motor stator winding LTB in APTB, and discharging rod upper contraction displacement output signals dPB are generated; and through RMTB detection and LCTB feedback, dPB is introduced into the uppercomparison link with sTB.

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...
