Embodiment Construction

[0009] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0010] see figure 1 The ECN process control system of the present invention includes an SMT production line control system 1, an ECN preparation module 2, an ECN approval module 3, an ECN configuration module 4, an ECN release module 5, an ECN response module 6 and an ECN closing module 7. The ECN preparation module 2 completes the preparation of the ECN content to generate an ECN file in electronic file format, and receives and sends an instruction to send the ECN file to the primary review link of the ECN approval module. The ECN file compiled is a paper file The electronic file of the ECN file has the same content. The ECN approval module 3 starts from the primary audit link and transfers to the next link and receives approval or disqu...

Abstract

The invention discloses an ECN (engineering change notice) process control system. The ECN process control system comprises an SMT production line control system, an ECN compilation module, an ECN approval module, an ECN configuration module, an ECN issuing module, an ECN response module and an ECN closing module. An ECN file is compiled through the ECN compilation module, the ECN file is approved by the ECN approval module, then the ECN content is configured through the ECN configuration module, finally the ECN content is issued to the SMT production line control system through the ECN issuing module, the ECN content is executed through the SMT production line control system so as to give an alarm and interrupt a production flow, after the ECN is confirmed on the site to be executed, a confirmation signal is generated by the ECN response module, a closing signal is generated through the ECN closing module, so that the configured ECN content is relieved by the SMT production line control system under the control of the closing signal, the ECN is prevented from being forgotten in the production process, and the execution control level of the enterprise ECN can be enhanced.

Description

technical field [0001] The present invention relates to control systems, in particular to ECN process control systems for SMT. Background technique [0002] In the prior art, the process control of SMT's ECN (Engineering Change Notice, which means engineering change notice in Chinese) takes the form of paper files. Such paper files usually include customer number, customer code, finished product order number, change item, reason for change, material status and so on. When ECN control is required, the operator will give the ECN file of the paper file to the relevant designated authority personnel for approval. After the approval is completed, the approval document will be given to the operator to execute ECN. In the actual process, there will be cases where the operator forgets to execute due to negligence. The situation of ECN makes the control level of ECN low. Contents of the invention [0003] The problem solved by the invention is that the ECN control in the existing...
