Automatic processing unit monitoring system and method

Abstract

The invention discloses an automatic processing unit monitoring system and method. The system comprises an automatic processing unit module, an industrial switch module, a remote monitor room module and a wireless terminal module. The automatic processing unit module is connected with the industrial switch module through a serial port server; and the industrial switch module is connected with the remote monitor room module. The automatic processing unit module is internally provided with a numerically-controlled machine tool monitor and an automatic jig monitor, which are used for sending the state data of machine tools and state data of jigs to the remote monitor room module to realize remote monitoring respectively. The automatic processing unit monitoring system and method have the advantages of being perfect in function, good in data transmission performance, long in monitoring distance, high in system openness, capable of reducing labor cost effectively, fast in alarm response speed, capable of reducing processing waiting and stalling time and improving production efficiency.

Description

technical field [0001] The invention belongs to the technical field of mechanical automation monitoring, and in particular relates to an automatic processing unit monitoring system and method. Background technique [0002] With the proposal of "Industry 4.0" and the release of "Made in China 2025", the practice of "smart manufacturing" has become a proposition actively explored by the industry. In the context of the transformation and upgrading of the manufacturing industry, various automated production lines have been deployed in large numbers, especially the automatic processing unit for loading and unloading outside the machine of "robots + multiple CNC machine tools + automated fixtures". This kind of automatic processing unit effectively solves the problems of high labor intensity of manual loading and unloading and poor control of feeding accuracy when processing large and heavy workpieces. However, the operation of the automatic processing unit is relatively complica...

AI Technical Summary

Problems solved by technology

[0003] At present, the monitoring system applied to the automatic processing unit of "robot + multiple CNC machine tools + automatic fixture" is relatively rare, or the form is relatively simple

Some monitoring systems are deployed on the touch screen, which can simply display and process the signals of related modules of the unit; some monitoring systems can monitor the state information of CNC machine tools, and most of them use special software provided by machine tool manufacturers. Monitoring; some monitoring systems are deployed near the unit and can only achieve limited distance data transmission

[0004] There are the following disadvantages: single monitoring function: the touch screen has a single function, which can only simply display and monitor the main control PLC signal in the unit, and cannot effectively monitor the operation of the robot and automation fixtures, which is far from meeting the monitoring requirements for the entire automation unit ; Poor data transmission: Most of the existing CNC machine tool monitoring systems use single-machine serial communication, and data information between machine tools cannot be shared in real time, which affects the production cycle of the entire processing unit; traditional serial communication also has low speed, poor reliability, and poor network characteristics. Disadvantages such as special wiring; short monitoring distance: touch screen and serial port machine tool monitoring systems are generally only deployed near the automation unit, and models with remote WEB functions are more expensive, increasing enterprise costs; low system openness: monitoring software provided by machine tool manufacturers is generally The interface is not open, and it cannot be effectively integrated with other systems (such as MES systems); labor costs are high; equipment management personnel in the monitoring room cannot leave for a long time, and production control needs to arrange special personnel to walk through the workshop, and labor costs are high. Alarm response delay: Each module of the entire processing unit has an alarm mechanism. If the alarm status information cannot be fed back to the equipment management personnel who are not on site in time, the automation unit will be in a processing waiting or stagnant state, reducing production efficiency
