Rework control method based on MES system

Abstract

The invention discloses a rework control method based on an MES system, and the method comprises the following steps: A, storing the information of an inspection sheet in an inspection sheet region after the inspection sheet completes the inspection and it is judged that rework is needed, and storing the product information in the inspection sheet in a to-be-reworked region; b, randomly taking oneproduct from the products of the inspection sheet according to the product information stored in the to-be-reworked area, and executing a production queue of a corresponding reworking procedure; c, judging whether the product meets rework conditions or not through a rework judging unit, if not, exiting the production process and giving an alarm; if so, entering a rework execution process; d, executing the product production flow of the procedure through a rework execution unit, marking the current procedure of the product to the next procedure, and notifying a data processing unit; and E, enabling the data processing unit to perform data updating according to the rework execution condition of the product. According to the invention, the problem that product rework production cannot be rapidly and efficiently carried out after inspection in the traditional MES is completed is solved.

Description

technical field [0001] The invention relates to the technical field of production and manufacturing, and more specifically relates to a rework control method based on an MES system. Background technique [0002] In the traditional MES system, the rework control method after the product inspection is very simple. After the inspection fails, two methods are usually used for rework. One is to use the offline rework process. The rework process of this method does not pass The management and control of the MES system leads to confusion in production management, production data cannot be traced, and it is difficult to find out the cause of quality problems. Another way is to create a new rework work order, and re-produce the products that need to be reworked according to the normal production process. Although this method can complete the production control and record data of the product in the MES system, the production efficiency is greatly reduced. Employees need to repeat man...

[0002] In the traditional MES system, the rework control method after the product inspection is very simple. After the inspection fails, two methods are usually used for rework. One is to use the offline rework process. The rework process of this method does not pass The management and control of the MES system leads to confusion in production management, production data cannot be traced, and it is difficult to troubleshoot the cause of quality problems

Another way is to create a new rework work order, and re-produce the products that need to be reworked according to the normal production process. Although this method can complete the production control and record data of the product in the MES system, the production efficiency is greatly reduced. Employees need to repeat many redundant production operations, and at the same time, the production process of the product itself is not standardized
