Key Takeaway: Enhancing Spray Painting Quality. AUBO robots offer excellent repeatability and precise spray painting trajectories, ensuring consistent spraying speed and uniform coating thickness. They can initiate the spray gun without any deviation, guaranteeing the desired spray thickness.Improving Spray Painting Efficiency with EoAT robots, there is an increase in product yield and better consistency, reducing the need for manual touch-ups and allowing for on-the-fly modifications of spray parameters without production line stoppages. EoAT robots exhibit high reliability, stable operation, and low failure rates, enabling continuous operation according to production requirements.
Spray painting is a crucial process in product manufacturing as it directly affects the appearance quality and represents a significant component of product value. The spray painting industry is facing a severe labor shortage due to challenging work environments and health hazards to human workers. As a result, more and more manufacturers are adopting robotic automated spray painting systems.
Industry Pain Points
Time-consuming and costly: The drawbacks of manual spray painting, such as low efficiency, coating performance, and paint utilization, have become increasingly apparent. With rising labor costs, relying on manual spray painting cannot keep up with the pace of economic development for businesses.
High technical barriers leading to labor shortage: Hiring a skilled spray painter requires paying high wages, but the high-risk work environment makes recruitment even more challenging. The spray painting industry is facing a labor shortage, which makes the introduction of automated spray painting a trend.
Health hazards in a high-risk environment: Spray paints typically contain hazardous chemicals such as benzene, toluene, and xylene. Volatile organic compounds and dust in the paint significantly impact workers' health, making them susceptible to occupational diseases like pneumoconiosis when exposed to such working environments for extended periods.
AUBO + Eco-partners
Collaborative empowerment for industry development
AUBO collaborates with eco-partners, integrating industry resources to provide automated spray painting solutions for different industries and customers. These solutions effectively improve coating quality, spray painting efficiency, paint utilization, and reduce labor costs.
Enhanced spray painting quality: AUBO robots exhibit excellent trajectory repeatability, precise trajectories, consistent spray painting speed, and uniform coating thickness. They can initiate spray gun operation without deviation, ensuring the specified spray thickness.
Improved spray painting efficiency: The yield of quality products increases with good consistency, reducing the need for manual touch-ups. Spray painting parameters can be modified without production stoppages. AUBO robots boast high reliability, stable operation, and low failure rates, enabling continuous operation to meet production demands.
Reduced labor and paint costs: Using AUBO robots for spray painting minimizes paint and spray wastage. Compared to traditional spray painting methods, this approach saves on labor assistance, reduces technical requirements, and conserves labor costs.
"Military-grade" explosion-proof protection
High safety level with IP65 rating
Spray painting work environments are harsh, with paint compositions consisting of chemical substances. Paint mist and other volatile gases produced during spraying are flammable and explosive, making the spray painting site as hazardous as a gas station.
As robots require electrical control, improper protection can lead to fires and explosions. Therefore, explosion-proof considerations are paramount when using spray painting robots in enclosed spaces.
Generally, robots used in special work environments should have an IP rating of at least 54. However, AUBO's explosion-proof collaborative robots boast a high IP65 protection level, effectively reducing safety risks.
To minimize external influences and extend their lifespan, the robots are typically equipped with waterproof and dustproof covers during actual production, ensuring stability and safety during spray painting operations.
"Drag-and-Drop" Operation
Lowering the learning curve for fast production
How to quickly master the skills of using robots and achieve rapid production is a primary consideration for companies when choosing robot-assisted production.
With AUBO robots, users can generate motion paths and intuitively teach spray painting tasks through drag-and-drop programming. By manually guiding the robot to specific positions or moving it along specific trajectories, users can easily teach the robot how to perform spray painting tasks. Additionally, EoAT, in collaboration with eco-partners, provides spray painting application packages, allowing users to control all spray painting parameters and flexibly operate them based on actual application requirements.
Spray painting poses significant hazards, and many factories allocate dedicated work areas for spray painting. These areas usually have limited space, requiring robots to possess high flexibility and freedom of movement while maintaining a compact size.
In a spray painting application at a water pump company, manual spray painting resulted in uneven coatings and high defect rates. By using the AUBO i5 collaborative robot for water pump spray painting, the application was quickly set up through drag-and-drop programming. The robot ensured a stable paint output and achieved uniform spraying on all angles and surfaces. Compared to manual spray painting, the defect rate of the products could be close to zero. The robot can adapt to different types of water pumps, improve production efficiency, and automate the process of water pump spray painting.
Increased Production and Efficiency
Higher Flexibility and Versatility
Spray painting involves significant hazards, leading many factories to allocate dedicated work areas for this process. These areas often have limited space, requiring robots to possess high flexibility and freedom of movement while maintaining a compact size.
AUBO collaborative robots occupy only 1m² of space and offer exceptional flexibility. The i-series collaborative robots have different payload capacities ranging from 3kg to 20kg. Each joint supports a ±360° rotation, simulating human hands and enabling spray painting from various angles. They can even handle the precise internal surface spray painting of intricate workpieces. Additionally, the robots can be installed in different ways, such as inverted or side-mounted, to meet diverse customer application demands.
In a case study at a plastic product manufacturing company, the harsh working environment and the inefficiency of manual spray painting posed challenges for the business. The company introduced the AUBO i5 collaborative robot, which held the powder spray gun. Utilizing a grid sensor, the robot achieved uniform powder spraying on the products, leading to nearly 100% utilization of the powder coating. With a repeat positioning accuracy of ±0.02mm, the robot accurately positioned and sprayed powder on the components of the workpieces, ensuring higher precision.
Compared to manual powder spraying, automated spraying achieves a rate of over 90%, resulting in a 30% increase in production efficiency and a 30% improvement in product quality. Labor costs are reduced by 50% as one person in this workstation is completely replaced by the robot, achieving the goal of human-robot substitution.
Of course, in addition to the mentioned applications, AUBO, in collaboration with its eco-partners, is continuously exploring new application scenarios. With technological advancements, more and more jobs will be replaced by automated equipment, freeing workers from strenuous and harsh work environments. This optimization of production efficiency reduces occupational hazards and provides a more friendly and safe working environment.
