SMT material mistake preventing and tracing method and system

Abstract

The invention provides an SMT material mistake preventing and tracing method and system. The method comprises the following steps that a database is established based on material information, and management is conducted; bar codes are established for materials and stored in the database; the material bar codes are recognized, and matching is conducted on the recognized information and the information in the database; if the material bar code information is matched with the information in the database successfully, the next step is conducted; if the material bar code information is failed to be matched with the information in the database, an alarm is sent out; and the bar codes of the materials which are processed completely are scanned, the scanning information is stored in the database, and the purpose of extracting production line data in real time can be achieved. It is not required to make feeding tables, feeding is carried out according to programs, material mistaking is prevented, and paper-free operation is achieved. Manual checking is not required, the efficiency is high, and no mistake will be made. The materials are sought quickly, the line exchanging efficiency is improved, and the employee pressure is lowered.

Description

technical field [0001] The invention relates to the field of SMT, in particular to a method and system for error prevention and traceability of SMT materials. Background technique [0002] The manufacturing industry is facing increasingly fierce competition in the industry, and more companies want to adapt to the changing needs of the market. However, the traditional production management is like a black box operation. It lacks effective supervision measures for output rate, yield fluctuation, process stability, etc. Problems can only be remedied afterwards and cannot meet the complex and ever-changing competition needs. Therefore, how to make the operation transparent, find out the problems that affect the quality and manufacturing cost, improve the immediacy and flexibility of the plan, and at the same time improve the operating efficiency of the production line, has become a concern of enterprises, such as in the field of SMT, in production There are often wrong material...

Problems solved by technology

However, the traditional production management is like a black box operation. It lacks effective supervision measures for output rate, yield fluctuation, process stability, etc. Problems can only be remedied afterwards and cannot meet the complex and ever-changing competition needs.

Therefore, how to make the operation transparent, find out the problems that affect the quality and manufacturing cost, improve the immediacy and flexibility of the plan, and at the same time improve the operating efficiency of the production line, has become a concern of enterprises, such as in the field of SMT, in the production There are often wrong materials and the finished product cannot be traced

caused a lot of quality problems
