Dalian Science and Technology Intelligent Technology Helps iPhone X Intelligent Production
Recently, Apple released the iPhone 8 and iPhone X. Dustproof and waterproof is a highlight of the iPhone 8 and iPhone X. The main equipment for this function is the glue dispenser. The traditional glue trajectory setting is manually calibrated. It is usually necessary to manually move the glue head to the vicinity of the glue point and use the eye to align. This method has poor accuracy and low efficiency. Professor Zhong Chongquan from the Department of Electronic Information and Electrical Engineering of Dalian University of Technology is based on a self-developed development platform for networked programmable logic control (PLC) technology and numerical control (NC) technology, and a workpiece coordinate system based on machine vision. Developed a smart glue robot control system. The intelligent glue spray robot is based on the spray trajectory planning method for machine vision teaching. Through image measurement, the glue point is automatically selected, and the actual coordinate value of the glue point is accurately calculated, which greatly improves the glue efficiency and ensures the product. Waterproof effect.
The control system adopts the self-developed MAC1620 motion controller, DIO series expansion module and Dview monitoring software development platform, and designs the 8-axis dual-station mobile phone shell waterproof spray glue robot control program. The motion controller combines a distributed control system (DCS), a programmable controller (PLC), a numerical control system (CNC), an embedded control unit (ECU), and a programmable automation gateway (PAG) into a unified development platform that supports graphics. The text and programming methods are used to achieve precise control of the dispenser in a non-contact manner. This solution is more cost-effective than other similar vendors in the market to provide motion control card solutions, so it stands out in the iPhone 8 and iPhone X process product lines. At present, the products of this program have almost covered all the factories in Foxconn nationwide, and the total equipment cost has exceeded RMB 170 million.
In addition, the team of Professor Zhong Chongquan developed the DELTA sorting robot to sort and place good and bad products on the iPhone 8 and iPhone X semi-finished packaging production lines. The robot uses the self-developed MAC1620 programmable controller robot model and motion control commands to apply visual alignment and trajectory tracking to achieve high-speed and high-accuracy automatic capture and placement functions. It has passed the iPhone 8 and iPhone X mobile phone surface. The scratch test, its work efficiency is much higher than manual sorting, and is currently being promoted and applied in Foxconn's whole package workshops.
At present, industrial automation based on intelligent manufacturing and industrial robots is developing at an exponential rate worldwide. "Machine substitution" has been widely used in the industrial manufacturing field. Intelligent robots, industrial Internet, industrial big data, artificial intelligence and other technologies have been integrated into the manufacturing industry to realize intelligent manufacturing and production of enterprises, effectively improving production efficiency and product quality.
Professor Zhong Chongquan is the subject of system control technology in the advanced manufacturing technology field of the National 863 Program, the national 13th five-year scientific planning expert in the field of advanced manufacturing technology, the national key research and development plan “network collaborative manufacturing†and the major project “Intelligent Manufacturing and Roboticsâ€. The research team relied on Dalian University of Technology to set up Dalian Science and Technology Computer Control Engineering Co., Ltd. (referred to as the Grand Engineering Control), which is the key high-tech enterprise of the National Torch Program, the fifth batch of innovative pilot enterprises in the country, and the first leading technology enterprises in Dalian. Has passed ISO9000 and CMMI3 system certification. On the basis of cooperation with Foxconn's intelligent glue-spraying robot and DELTA visual sorting robot, Dagong Jikong and Dalian University of Technology and Foxconn have applied for the national key R&D plan intelligent robot special project, focusing on the robot controller in intelligent perception and depth. Key technical problems in learning, independent decision-making, etc., provide technical support and security for robots in related industries.
