Lamination stacking machine based on machine vision and sheet stock calibration method and control method thereof

Abstract

The invention discloses a lamination stacking machine based on machine vision and a sheet stock calibration method and control method thereof. According to the lamination stacking machine, on the one hand, the sheet stock calibration method of the lamination stacking machine based on machine vision is introduced, a Yolo3 network and Hough conversion are combined to achieve stacking calibration of sheet stocks, sheet stock typesetting is more orderly, and the stacking stability is higher; and on the other hand, the lamination stacking machine can further achieve automatic ascending of a sheet lifting area and automatic descending of a finished product lifting table, the material taking height on the sheet lifting area is consistent with the material discharging height on the finished product lifting area, and therefore the action circulation of a mechanical arm is consistent, and the typesetting efficiency of lamination is greatly improved. The lamination stacking machine can be directly applied to prepreg stacking, and a series of problems caused by manual prepreg stacking in the existing PCB production process are solved.

Description

Technical field [0001] The present invention belongs to the field of laminating machine, and more particularly to a machine-visual laminated machine and a sheet calibration method and a control method thereof. Background technique [0002] The semi-curing sheet is one of the main materials necessary in the PCB design process. It is a sheet material made of treated glass fiber cloth, impregnated with resin glue, and then heat treatment (prefabrication) to entert the resin into the B stage. In the production workshop of the PCB board, there is a production process to make different types of semi-cured sheets in the formula stack. At present, most of the manual stacked semi-solidized sheets are laminated, the workload is large, the stack is not neat, the working efficiency is low, it is difficult to match the machine Synchronization, it is not conducive to subsequent transport packaging, and long-term repetitive labor is easy to cause harm to workers' health. In order to solve the p...

Problems solved by technology

[0006] The purpose of the present invention is to provide a machine vision-based lamination machine and its sheet material calibration method and control method for the technical problem that the existing lamination machine lacks a sheet material calibration mechanism, resulting in uneven stacking. There is a sheet material calibration subsystem, which uses a machine vision-based sheet material calibration method to realize the sheet material calibration during the stacking process, further ensuring that the sheet materials are stacked neatly, especially it can be directly applied to the field of prepregs, and solves the problem of Prepreg Stacking Issues
