Virtual product switching method for electronic product production line

Abstract

The invention discloses a virtual product switching method for an electronic product production line. The method comprises the following steps of performing modeling in a simulation platform accordingto layout planning of a main assembly line and a special production platform required for electronic product switching, and building a three-dimensional model library in an upper computer; performingmodularization on the built three-dimensional model library and performing packaging; in combination with the three-dimensional model library, performing unit modularization algorithm solving, wholeline execution and scheduling algorithm, and determining an initial scheme of product switching; quickly rebuilding the three-dimensional model library realized in the upper computer through flexiblescheduling by the special production platform; performing whole line assembly by the three-dimensional model library, performing logic script compilation on the rebuilt three-dimensional model library, and finally performing re-packaging; performing whole line product switching virtual testing of the main assembly line on a test module of the upper computer for the rebuilt three-dimensional modellibrary; and generating a product switching test result, and according to the product switching test result, generating a production line optimization design scheme.

Description

technical field [0001] The invention relates to the technical field of industrial automation, in particular to a virtual replacement method for an electronic product production line. Background technique [0002] The status quo of traditional electronic product production lines: the production characteristics of multiple varieties and small batches are the common characteristics of many enterprises, especially for electronic product manufacturing enterprises, the product life cycle is short, and the update iteration is fast, resulting in a wide variety of varieties, and the demand for a single variety not much. [0003] Taking the core production process of the electronic manufacturing system as an example, the core process is to assemble electronic components on a printed circuit board to realize the interconnection of electronic components, and the assembly process mainly involves Surface Mounting Technology (SMT). At present, the production change time of SMT equipment u...

AI Technical Summary

Problems solved by technology

The traditional high-volume processing mode has caused the following problems: 1) The traditional high-volume processing mode has led to increased competition for SMT equipment resources

2) Long production cycle

The amount of SMT equipment for one surface paste is 2 weeks, and the subsequent process cannot be consumed in time. There are a large number of work-in-progress between processes, which makes the production cycle longer, increases the capital occupation, and also affects manufacturing flexibility. The production line cannot be quickly switched to other products.

3) There is a quality risk of unqualified batches

Due to the long cycle and large batches, once unqualified products are found, there are often a large number of them, and they cannot be remedied in time
