In 2011, Foxconn proposed the "Million Robot Project." What is the status quo now in the past 8 years? According to its 2018 annual report, Foxconn and its affiliates currently have more than 80,000 robots, more than 1,600 [s>smt production lines, more than 170,000 mold processing equipment, and more than 5,000 types. u>Test devices, more than 3,000 third-party developers, more than 1000 apps. Among them, naturally, the logistics handling AGV figure is indispensable.
Step-by-step advancement of the factory
Foxconn has spared no effort in promoting the unmanned lighting factory. In April this year, Li Junqi, chairman of Industrial Fulian, told the media.Based on the accumulation of industrial production data, production scenes, and production content of the Foxconn Group for 30 to 40 years, the attempt of the Industrial Fulian in the “light-off factory” in 2018 is an internal test. Currently, the company is already in precision tools and communication equipment. u>Manufacturing The panel completed the transformation of the “light-off factory” model. In 2018, its “light-off factory” realized revenue of 4.766 billion yuan. Li Junqi also said that the "light-off factory" is currently only in its infancy.
Intelligent Manufacturing + Industrial Internet, Foxconn's light-off factory is to Create a new manufacturing form. And the future,The head enterprises of the entire 3C electronics industry will also strengthen the<5>5G business and continue to explore how the Industrial Internet can empower manufacturing companies and promote smart manufacturing.
Exploration of logistics automation
Like Foxconn, 3C industry head customers for AGV The application is also in the forefront of various industries. At the same time, such as ZTE, Foxconn, etc., the selection of AGV suppliers is also very strict, for large manufacturing companies, security and stability is very important, therefore, to enter Foxconn, Huawei and other 3C For industrial head customers' factories, AGV products must undergo multiple rounds of verification. However, unlike the brands such as Huawei, due to the nature of the company, Foxconn and other foundries will have higher demand for product flexibility.
Beyond security and stability,Flexibility becomes just needed
As the world's largest electronics OEM, Foxconn's production line is extremely rich. As far as the mobile phone is concerned, in addition to producing well-known Apple mobile phones, he also produces mobile phones of domestic famous brands such as Huawei, Xiaomi and OPPO. Therefore, the production line changes very frequently, even once every month, to reassemble the combination. This kind of flexible production requires more flexible and rapid conversion of workflow, deployment and low-cost operation, efficient and reliable operation. Therefore, in the selection process of AGV manufacturers, such as Foxconn and other 3C industry large-scale foundry companies, the ability to adapt to this flexible demand has been placed in a more important position.
For example, in the SMT workshop of a 3C foundry company, the agv car running from it is to create a more stable and reliable Flexible Robots are targeted for flexible handling.
In the SMT workshop, the AGV handling cart , the automatic delivery of the warehouse electronic material. According to the production instructions, AGV automatically transfers materials from the warehouse to the production line to improve production efficiency, reduce labor costs and reduce labor intensity. First, the warehouse workers will arrange the materials on the material truck according to the production plan and the production line, and put the material truck to the issues site, and then issue the dispatching instructions. After receiving the dispatch instruction, the AGV dispatching system deploys the AGV to perform the task automatically.According to the production instruction, AGV sends the materials to the designated loading site in turn. After the delivery is completed, the empty material truck is sent back to the kit to remove the empty material truck to complete the entire distribution process.
In addition to the automatic loading and unloading of the workshop, other materials in the workshop The distribution link is also active in the Stade AGV. The composite AGV in the figure below can be used in one car. It can transport pallets on the 1st floor and send the trucks to the SMT line on the 3rd floor from the warehouse area of the 1st floor. At the same time, it can communicate with the elevator to realize materials. Automatic delivery across floors.
This project uses 11 traction Oasis300 robots, carrying a rotating composite mold There are 8 Oasis300 robots and 1 Oasis600 robots for automatic loading and unloading. The total number of Oasis600 robots is 20, and the application scene runs through the raw material warehouse-line side warehouse-production line, covering more than 8,000 square meters of factory space, instead of 48 people, it can completely replace the material distribution of the workshop. The staff and part of the loading and unloading workers, only a small number of adjustment personnel left in the workshop, improve production efficiency of nearly 10%, ROI is about 13 months, better meet customer needs, and achieved customer planning results.
The difficulty of implementation of this project is that the production workshop environment is more complicated, the personnel flow is frequent, and the natural navigation AGV can be safely and stably operated under the dynamic environment; The information is automatically sent to the FMS dispatch management system by the MES system. The reliability of information transmission and the traceability of quality management need to be ensured. The AGV adopts the method of trackless natural navigation. Some channels are narrow, and long-term operation requires high positioning accuracy. A large amount of cargo backlog is likely to cause the channel to be blocked, and the agility and intelligence of the robot and the dispatching system are relatively high.
At present, the project has been delivered online for 5 months.The site operates 65 days without trouble, and works 24 hours a day. On average, each AGV carries about 50 baht per day and works 7 days a week. The minimum channel size of the running route is 900mm, and the minimum clearance of the AGV is only 20mm. In the field of lasers, it is also the embodiment of the company's technical level to meet such demanding requirements.
Standardization, collaboration still needs to be explored
Safe, Stable, flexible... After applying the convenience brought by AGV products, there are actually some problems that need to be explored.
First of all, for the head enterprises such as Huawei and Foxconn, the volume is too large, and suppliers cannot have only one or two, but when they come from different How do manufacturers make their contracts work when the AGVs of the manufacturers gather in the same workshop? The person in charge of the relevant 3C company once said that "the choice of automation equipment is carried out through tendering.In this way, we can have better bargaining power, so it is impossible to use only one automation device, and the device interface is not uniform, the system is not compatible, and it is very difficult to achieve large-scale application of the whole plant.
In addition, the current AGV technology iteratively faster, the company purchases in large quantities The product is likely to be “outdated” right away, especially for 3C head companies like Foxconn. How can the existing AGV products be upgraded after the new generation of technology comes out? How should the previous generation equipment be used? It won’t cause so much idleness.How to achieve maximum economic benefits is a very real problem.
In addition, there may be other different issues in the specific application environment, for example, some may also involve site utilization, equipment Post-maintenance and the impact of special environments on AGV operations. In general, how to better apply AGV in the 3C industry will be solved in the future by the application side and the supplier.
