The telescopic control system of the blanking rod of the plate-shaped workpiece hemming device

Abstract

A blanking rod telescopic control system of a plate-shaped workpiece hemming device is composed of upper and lower comparison links and blanking rod operation control link C dB , The large scale link A on the operation control system of the blanking rod PTB , The lower extension link A of the blanking rod operation control system NTB , Stator winding L of blanking rod telescopic motor TB , The feeding rod is retracted to the magnetic resistance R MTB , The feeding rod is retracted to the position signal optocoupler LC TB And unloading rod touch pressure signal detection link DT SB constitute. The feeding rod is given a retracting displacement signal d BR Retract position signal s with blanking rod TB Compare, generate the deviation signal △d of the upper retraction displacement of the blanking rod TB ; via C dB , Δd TB It becomes the control signal d of the upper retraction displacement of the blanking rod PBC in A PTB middle control PB Drive the blanking rod telescopic motor stator winding L TB , the output signal d of the retraction displacement of the blanking rod is generated PB ; via R MTB detection and LC TB feedback, d PB with s TB Introduce the comparison section above.

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...
