Control System of Belt Feeding Mechanism of Hemming Device for Plate-Shaped Workpiece

Abstract

A feeding belt mechanism control system of a plate-shaped workpiece edge-wrapping plate-shaped workpiece edge wrapping device, from the upper and lower comparison links, the main motor to the second normally open contact of the 3-position relay J n3 ‑2. The fourth normally open contact J of the standby position relay of the feeder mechanism W0 ‑4. Rocker arm motor M W , The feeder mechanism swings back to the position of the reed switch Drp W0 , Feed belt mechanism swing back in place relay freewheeling diode D W0 , The belt feed mechanism is left on the pressure control link C sBP , Feeding belt mechanism left by the pressure control system amplification link A W And belt pressure signal detection-amplification link DT BP constitute. Arm close pressure given signal s BPR Close to the elastic arm pressure feedback signal s BP Comparing in the next comparison link, the elastic arm is close to the pressure deviation signal △s; sBP computing processing, A W Zoom in, and finally produce e PW Drive M W , to generate the elastic arm close pressure output signal s PBP ; via DT BP then s BP Introduce the next 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...

Problems solved by technology

[0003] In order to solve the problems of poor consistency of wrapping state, deficiencies such as partial sticking, folds, and leaks, as well as cumbersome manual wrapping operations, the present invention provides a belt feeding mechanism control system for plate-shaped workpiece edge wrapping plate-shaped workpiece edge wrapping devices. Up and down comparison link The main motor turns to the second normally open contact J of the 3-position relay n3 -2. The fourth normally open contact J of the standby position relay of the feeding belt mechanism W0 -4. Rocker motor M W , The feeder mechanism swings back to the position of the reed switch Drp W0 , Feed belt mechanism swing back in place relay freewheeling diode D W0 , The belt feed mechanism is left on the pressure control link C sBP , Feeding belt mechanism left by the pressure control system amplification link A W And belt pressure signal detection-amplification link DT BP constitute
