Plate workpiece hemming system software feeding and return process

Abstract

A software loading and return process of plate-shaped workpiece edge wrapping system, which is the following 5 steps: 1: The main motor rotation angle feedback signal n value of the main motor rotation angle feedback signal is increased to n=n 3 , that is, the main motor turns to the 3rd position → the feeding rod gives the upward and downward displacement signal d TFR assignment 0 → LC PTF Work → The feeding rod retracts upward and runs the isolation relay electromagnetic coil J T1 Power on→feeder rod shrink→s F The value increases → the contact pressure of the feeding suction cup returns to zero; 2: If the feeding rod is retracted to the position, the magnetoresistor R MTF value reduced to R MTF =The minimum value R of magnetoresistor when the feeding rod is retracted to the position MTF0 , that is, the feeding rod is retracted to the right position, and go to step 3; otherwise, the feeding rod continues to retract; 3: The feeding arm swings outward, → the α value of the feeding arm swing angle feedback signal decreases; 4: If the α value reduced to α=α 0 , that is, the loading arm swings outwards in place, and go to step 5; otherwise, the loading arm continues to swing outwards, → the value of α decreases; 5: end.

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...
