Industrial robot technology from abroad has become increasingly mature and is now considered a standard equipment widely used in the industrial sector. These robots are typically categorized into Japanese and European systems. Leading Japanese manufacturers include Yaskawa, FANUC, and Kawasaki, while European brands such as KUKA (Germany), ABB (Sweden), and COMAU (Italy) are also prominent. The low level of localization in industrial robots is largely due to domestic brands not matching foreign counterparts in terms of cost efficiency and reliability. For example, the average time between failures for domestic products is around 8,000 hours, whereas foreign equivalents can reach tens of thousands of hours. As industrial robots become more prevalent in manufacturing, their adoption is expected to address labor shortages in China, where workforce availability continues to be a challenge.
**1. FANUC Intelligent Machine Tool Loading and Unloading Industrial Robot**
The production of bridge box parts involves high precision, multiple processing steps, complex shapes, and heavy weights. To enhance accuracy and efficiency, many heavy-duty automotive manufacturers use CNC machining centers. However, precise positioning of workpieces on the table is critical, and maintaining consistent feeding is essential. Traditional manual loading methods suffer from high labor intensity and poor control over precision, leading to a shift toward industrial robots or specialized machines. Robots offer advantages such as high repeatability, reliability, flexibility, and automation. Compared to human labor, they significantly improve productivity and product quality. Compared to dedicated machines, they provide greater flexibility and lower investment costs. **...>> Click for details**
**2. Breakthroughs and Solutions for Stäubli Industrial Robots in Automotive Flexible Production Lines**
Stäubli has over a century of experience in precision mechanical design and high-speed motion control, making it a key player in the automotive industry. In response to the need for flexible production, Stäubli introduced the RX160L flip-chip gantry structure robot solution for flexible cutting systems. This system made significant breakthroughs in several areas:
**Breakthrough 1: Large-Scale Robot with Wide Working Area**
The RX160L robot offers a 2.05-meter ball working area, allowing cutting tables up to 3 meters wide. Most automotive parts fit within this range, and larger workpieces can be handled using mobile platforms. Unlike other general robots that have non-spherical working areas, the RX160L avoids dead zones, ensuring continuous and uninterrupted cutting—something that automotive customers find highly acceptable. **...>> Click to see details**
**3. Nachi Industrial Robot on Flexible Production Line**
In many industrial applications, surface treatment and processing of non-standard parts are challenging due to their complexity and diversity. Manual labor is often impractical, and programmable robots may face limitations. As a result, the design of custom non-standard robots or machines has become an important technical field, requiring advanced expertise. The higher the level of automation, the easier it is to manage production planning. Therefore, using flexible and general-purpose equipment is a smart approach for modern manufacturing.
With increasing individual preferences, aluminum alloy electroplated car hubs are becoming more complex and diverse, leading to frequent replacements. Currently, polishing is done manually, which takes about 35% of the total time and labor in wheel production. Skilled workers are needed, but the process generates large amounts of dust, posing health risks and environmental concerns. Low efficiency and high workload are major challenges for companies. To address this, Nachi has developed a cost-effective polishing robot system tailored for the automotive wheel industry. **...>> Click for details**
