In the 1990s, the United States chose the science and technology development strategy of the information superhighway, and Japan chose artificial intelligence and robotics. After 20 years, the development of the Internet has far exceeded that of robots, and the United States has also stood at the pinnacle of the trend of science and technology.
Today, the Internet is still the mainstream, but more and more people are predicting that robotics and automation will be the next revolutionary technology to change the world. Foxconn 1 million robot plan to echo this prediction. The advent of the robot era no doubt. So, at this moment, whether China's industry is ready? IT companies can make robots more intelligent? CCID think tank equipment industry research institute director left all told reporters that China's domestic robotics enterprises to master the technology maturity is not enough, but also to strengthen the reliability. Zhang Hui, head of precision assembly department of ABB Group China Robotics Division, one of the four largest robotics companies, told reporters that industrial robotics is a mechatronic industry where IT companies can develop advanced artificial intelligence software systems.
China's demand is on the rise
It is estimated that the demand of industrial robots in China will reach 32,000 units by 2014, becoming the largest demand country in the world.
Industrial robot usually consists of three parts - mechanical systems, control systems and intelligent systems. Mechanical systems include drive mechanisms (eg hydraulic, pneumatic and electric) and actuators (consisting of base, waist, arm, wrist and hand). The hand is also called the end effector and can be a jaw, a torch or a nozzle, depending on the application. The control system is responsible for calculating the spatial coordinates required for the hand at work, and cooperating with the steering of the joint axis on the base, the waist, the arm and the wrist to determine the working attitude of the robot. Intelligent system is through the computer software computing, determining the best hand-point or point-to-point or continuous moving route, and interference analysis to avoid collisions with the workpiece, fixtures and other equipment, and quickly output the work process, command and control system to achieve the required Work results.
Overall, today's industrial robot is a system that integrates electromechanical and computer software. Enterprises must have good mechanical, servo-motor, and precise deceleration And sensor systems engineering design and analysis capabilities to master a comprehensive computer simulation, visualization and programming capabilities, and fully understand the application of industry standards and needs.
Industrial robots in China started in the early 1970s. After more than 20 years of development, they have undergone three stages: the germination of the 1970s, the development of the 1980s and the application of the 1990s. Since the development of industrial robotics, China's industrial robot industry continues to progress.
All left told reporters in recent years, China has emerged in recent years, the new pine robotics, Boshi automation, Aifu Te (Chery equipment), a giant welding, CNC Guangzhou, Woddy, Qingdao soft control nearly 60 engaged in industrial robots Production enterprises, but the product is less industrialized, mostly in dozens of units of production scale.
In terms of applications, the market demand has surged in the recent three years and the automobile industry has expanded to many fields such as power and electronics , machine tools and chemicals, and the demand for the market is huge. Starting in 2010, the demand for industrial robots in China surged, an increase of 1.7 times over 2009, an increase of 51% over 2011 and expected to reach 32,000 units in 2014, making it the world's largest demand country. This is mainly because of the rapid rise of labor costs in our country, and some enterprises started to replace artificial labor with industrial robots.
Foreign brands occupy most of the market
80% of China's market share is occupied by ABB, FANUC, Yasukawa and KUKA.
In recent years, the popularization and application of robots has evolved from the initial single-robot working unit into a working group of multiple robots, and can even form a production line that completes the entire manufacturing process.
Speaking of international and domestic disparities, Lei Weiming told reporters that both international and Chinese markets have similarities in robot performance concerns such as large working space, fast speed, short response time, high precision and reliability, light weight and heavy weight , High flexibility, operator interface improvement, modularity, offline programming (OLP), energy saving, relatively low operating costs and other conditions.
However, due to the difference in labor costs, the Chinese market still uses manual loading, unloading and stacking operations when performing robotic production, resulting in a low level of automation and a low ratio of robots to manual labor compared to foreign markets And so on. According to the data from the International Robot Federation, China recorded 21 such stations in 2011 with an average international level of 55, of which 135 were in the United States, 251 in Germany, 339 in Japan and 347 in South Korea.
In the Chinese market, Japanese and European brands accounted for the majority of robot products. It is understood that 80% of the Chinese market share is occupied by ABB, FANUC, Yasukawa and KUKA four companies. Lei Weiming analysis believes that these foreign brands by starting early technological advantages and practical experience, the performance of the robot, especially the control system, intelligent and network performance than the Chinese products ahead. However, the performance of robot products developed locally in China is limited to a series of products such as articulated devices, points, handling and palletizing robots, which lack their autonomy. For example, the precision of parts processing is not high enough, the key components are almost entirely imported, the research and development power is fragmented and discontinuous, Influential local large enterprises to self-developed enthusiasm is not high, the production volume and other small factors, have hindered the development of China's robot industry chain.
Sheet metal fabrication processing is formed by laser cutting or stamping process, shear and bending, bending, bending, welding, riveting. The Sheet metal fabrication used are cold-rolled plate (SPCC), hot-rolled plate, galvanized plate (SHCC) (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum (5052), stainless steel. Sheet metal fabrication processing steps: according to the parts drawing (3D) expanded into a plan (2D), laser cutting or die stamping shape, CNC punching each bending part, should pay attention to the direction of the burr of the workpiece. Then the students are welded or riveted (some). Surface treatment after processing: electroplating, passivation, sand blasting (powder), anode treatment. Products are generally made for the connection and the outer cover. Applications in robotics, drone, communications, medical devices, industrial automation equipment.
