Feeding Rod Telescopic Control System of Plate-shaped Workpiece Hemming Device

Abstract

A feeding rod telescopic control system of a plate-shaped workpiece hemming device, which consists of an upper and lower comparison link and a feeding rod operation control link C dF , The upper zooming link A of the feeding rod operation control system PTF , Loading rod operation control system down-extending enlargement link A NTF , Stator winding L of telescopic motor for loading rod TF , Magneto-resistor R MTF , The signal optocoupler LC of the upper retraction position signal of the loading rod TF And the contact pressure signal detection link DT of the feeding rod SF constitute. The feeding rod gives the upward and downward displacement signal d TFR With the signal s of the upper retraction position of the feeding rod TF Comparing and generating the deviation signal △d of the retraction displacement of the loading rod TF ;△d TF by C dF Become the control signal d of the retraction displacement of the loading rod PFC ;d PFC in A PTF Middle control feeding rod telescopic motor stator winding retraction drive signal e PF Drive L TF , to generate the output signal d of the retraction displacement of the loading rod PF , via R MTF and LC TF to s TF Introduce the comparison link.

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...
