Board-shaped workpiece hemming system software blanking and return process

Abstract

A blanking and returning process of a plate-shaped workpiece hemming system software is divided into two stages: the retracting process of the blanking rod and the internal swinging process of the blanking arm. The retraction process of the feeding rod is: 1: the feeding rod shrinks → the feeding suction cup touches the low position; 2: the feeding rod shrinks; the feeding suction cup touches the low position; 3: if R MTB value reduced to R MTB =Minimum value of magnetoresistance R when the feeding rod is retracted to the position MTB0 , that is, the feeding rod is retracted to a certain position, → end; otherwise, go to step 2. The internal swing process of the blanking arm is as follows: 1: The magnetoresistive resistance value of the blanking rod is reduced to R MTB =Minimum value of magnetoresistance R when the feeding rod is retracted to the position MTB0 , → the given arm swing angle signal β R Assign as the swing angle of the lower material arm to get the material level signal β 1 value; - inner swing of the lower arm; 2: If the value of β increases to β = β 1 , that is, the feeding arm swings inwards, → end; otherwise, the feeding arm continues to swing inwards, → the value of β increases.

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...
