Software feeding return process of plate-shaped workpiece edge covering system

Abstract

The invention discloses a software feeding return process of a plate-shaped workpiece edge covering system. The process comprises the following five steps: 1, increasing a main motor corner feedback signal n value to n = n3, namly, a main motor rotates to a third position, a feeding rod gives an upward shrinkage displacement signal dTFR to be assigned with 0, LCPTF work is conducted, a feeding rodupward shrinkages to operate an isolation relay to power on an electromagnetic coil JT1, a feeding rod shrinks, an sF value is increased, and a feeding suction cup is pressed to return to zero. 2, ifthe RMTF value of the magnetoresistor with the feeding rod contracting upwards in place is reduced to RMTF = the minimum value RMTF0 of the magnetoresistor with the feeding rod contracting upwards inplace, namely the feeding rod contracts upwards in place, the step 3 is executed; otherwise, the feeding rod continues to shrink upwards; 3, the feeding arm swings outwards, and the value of a feeding arm swing angle feedback signal alpha is reduced; 4, if the alpha value is reduced to alpha = alpha 0, the feeding arm swings outwards in place, and the fifth step is executed; otherwise, the feeding arm continues to swing outwards, and the alpha value is decreased; 5: ending is carried out.

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...
