With the continuous intensification of global economic integration, China, as a large manufacturing country, has made great breakthroughs in the fields of electronic assembly, SMT patch, PCB assembly, etc. The scale and number of enterprises continue to increase, resulting in increased cost pressures, Short product life cycles, increasingly complex equipment, lack of transparency, and unknown demand forecasts have all become important factors in today’s world electronic manufacturing competition. The fierce competition, tighter product profits, product quality safety assurance, increasingly stringent regulatory requirements, and the importance of global market and brand maintenance have placed higher demands on companies in the electronics assembly industry. The implementation of MES will be A good way out for enterprises.
Many companies that implement MES have already tasted the benefits brought by the improvement of production traceability. MES (Manufacturing Execution System) has begun to be paid attention to by more companies. The promotion and application of MES has become one of the important tasks of manufacturing information engineering. , Has a good development prospect.
MES core controller
MES production management system uses industrial Ethernet, ProfiBus field bus, tablet computer, LED display, radio frequency identification, barcode recognition and other technologies to realize data collection with various processing equipment (screen printing machine, placement machine, AOI, etc.) And control, information is released through the LED display screen to realize the functions of quality control, material pulling, information release and operation guidance of the assembly process.
The MES production line management system is based on a large number of network hardware equipment and barcode scanning equipment. The normal operation of these equipment ensures the stability of the system and is the prerequisite for the safe, efficient and stable operation of the production workshop management system. The main hardware equipment includes: PDA mobile data collector (Stations for loading, assembly, inspection, testing, etc.), PDA mobile data collectors (stations for raw material storage and finished product removal), on-site industrial tablet computers (for on-site station data collection), barcode scanners (use On-site operation and barcode scanning), wireless network (for workshop and warehouse wireless network deployment), barcode printer (for barcode label printing and nameplate printing), industrial computer and PLC bus connection cables, sensors, etc.
One of EVOC Tablet PC PPC series
As far as an SMT production line is concerned, EVOC tablet computers are installed behind the printing solder paste screen printer, C-type material placement machine, A-type material placement machine, coil material placement machine, after furnace, AOI visual inspection station It is mainly used to complete production product parameter status display, system operation status control and display, historical data query and statistics, and fault maintenance records query. By setting user access rights, the safe and reliable operation of each production equipment is ensured, so as to meet the enterprise’s real-time monitoring and comprehensive traceability requirements of the production process.
It has four requirements for the system:
1. Easy installation in different environments, PC-based internal SAP system and company integrated network;
2. The equipment must be durable, waterproof and anti-vibration;
3. The whole machine can work in a wide temperature range, and the working temperature is between -20 and 70 degrees;
4. Rich interfaces can realize real-time collection of running status and reliable data transmission.
EVOC products perfectly meet the above system requirements, showing the following characteristics:
The system is stable, anti-seismic and shock-resistant, and has a long mean time between failures;
Efficient transmission rate, convenient installation and disassembly;
The whole machine has a compact structure and a fanless low power consumption structure;
Rich interfaces can realize real-time collection of operating status and reliable data transmission;
Can work in a wide temperature range.
Among the installed applications, the tablet computer is the workstation of the production line operator, and the interactive man-machine interface with software is very easy for the operator to operate. EVOC provides fast customer service to ensure the smooth execution of the project; in any particular project, EVOC can provide a wide range of equipment options, the products are sturdy and durable, and can make the system run stably in a variety of specific environments for a long time. EVOC tablet computers follow the style of EVOC products.
