SMT ((Surface Mount Technology) closed-loop integrated optimization system and optimization method thereof

Abstract

The invention discloses an SMT ((Surface Mount Technology) closed-loop integrated optimization system and an optimization method thereof. The SMT closed-loop integrated optimization system comprises a data acquisition module, a chip mounter performance evaluation module, an integrated optimization module and a database management module. The optimization method comprises the steps of: when an SMT production line is started, firstly obtaining performance indexes of the chip mounter and combining with PCB (Printed Circuit Board) information by the integrated optimization module to obtain a balanced optimization scheme; distributing the production plan through the balanced optimization scheme; at the same time, acquiring physical parameters in the mounting process of the chip mounter and the chip mounting quality parameters after the production are acquired in the running and producing process of the chip mounter of the SMT production line; obtaining performance indexes of the chip mounter and feeding back the performance indexes to the integrated optimization module to serve as the reference basis of selecting the chip mounter when the balanced optimization scheme is obtained after the next SMT production line is started. In addition, repeated optimization is carried out when a sudden event occurs. According to the invention, the performance of the chip mounter and the PCB information are considered in the optimization process, and the production efficiency and stability of the whole SMT production line are improved.

Description

technical field [0001] The present invention relates to the technical field of surface mount technology (Surface Mount Technology, SMT) combined with computer-aided management, in particular to an SMT closed-loop integrated optimization system and an optimization method thereof. Background technique [0002] SMT is an electronic assembly technology that directly and automatically mounts electronic components on a printed circuit board (Printed Circuit Board, PCB), and then uses solder to form a good mechanical and electrical connection between the components and the PCB. It is widely used in electronic manufacturing. Technology. The SMT production line is mainly composed of testing equipment, printing equipment, placement machines, welding equipment, cleaning equipment, etc. [0003] In recent years, the electronic assembly industry has developed rapidly.
