At present, China's manufacturing industry is constantly moving forward on the road of “manufacturing” to “intellectual creation”. Accelerating the "China's smart creation" process is inseparable from the smart factory, "Made in China 2025" clearly proposes to promote the intelligentization of the manufacturing process, through the construction of intelligent factories, to promote the simulation optimization of manufacturing processes, digital control, real-time monitoring of state information and adaptive control, In turn, the intelligent control of the entire process is realized.
Today, we introduce a typical case of a large-scale panel manufacturing enterprise in China, which will help you to improve the automation level of enterprises and build smart factories through smart transportation.
In recent years, with the strong support of the state and the related investment of key enterprises, the automation level of the semiconductor and panel industry has been rapidly improved, and the previous process has been highly automated. However, in the latter section of the module, there are still many processes that need manual and manual, which lowers the overall automation level of the industry. In actual production, in order to ensure 24 hours of continuous production of the production line, the factory needs uninterrupted inspection and timely feeding, and the transfer of production line materials is determined by the on-site staff according to the actual situation, relying on the subjective judgment of the personnel to carry, very It is difficult to guarantee that the production plan will be completed on time. The logistics and automatic transfer in the module factory has become one of the goals of the factory to optimize the production process and improve the automation level.
In order to achieve this goal, the combination of the MES (Manufacturing Execution System) system and the AGV (Automated Guided Vehicle) transport is indispensable.
As the executor of production, MES system monitors the progress of production orders in real time, improves the efficiency of factory personnel, manages product quality, timely corrects problems in production, and comprehensively tracks materials, equipment and time in the production process. It provides guarantee for enterprises to reduce costs, deliver on schedule, and improve service quality.
The AGV is an automated conveyor that allows flexible movement and docking between process equipment and shelf areas through a precise navigation system.
In this case, the MES system integrated AGV transfer, perfect release of the inspectors and field staff in this link.
The MES system monitors the production demand signals of each process equipment at all times. When the equipment initiates the request, the MES system automatically sends the transport command to the AGV trolley according to the equipment production capacity. After receiving the instruction, the AGV trolley transports the process products from the shelf storage area to the designated At the same time, for the products completed by the current equipment process, when the equipment initiates the production completion signal, the MES system will automatically send a transfer instruction to notify the AGV car to take the receiving action and send the product to the designated storage area.
For the material part, the MES system will monitor the stock of the temporary storage area of each equipment. When the remaining quantity of the stock reaches the warning water level, the production personnel can prepare the materials according to the warning information in real time, and pass the materials through the AGV trolley to send the materials from the line side warehouse. Transfer to the designated equipment staging area to ensure the continuity of production.
The integration of the MES system and the AGV transport enables the automatic transfer of good products, the storage of abnormal products, the timely delivery of defective products, the timely replenishment of materials and the recycling of wastes, effectively opening up the information channels between the process equipment and the shelf storage area. The realization of unmanned products and materials transfer, on the one hand, reduces the risk of abnormalities caused by manual manual transfer of personnel, on the other hand, it reduces the difficulty of factory management and improves the degree of on-site automation.
