Hardware equipment session: how robots can break through the underlying technical barriers The guests participating in this dialogue are: Song Gaosheng, Technical Director of Mitsubishi Electric Semiconductor Greater China, Ji Shuting, Deputy Dean of the Intelligent Transmission Technology Research Institute of Zhitong University, Gui Xinfei, Deputy General Manager of Benrun Harmonic, Tang Weiwei, Senior Director of Bitmain, Miao Yuqun, general manager of Daru Technology. The underlying technology is often the place where the barriers are concentrated, which has caused the gap between domestic and foreign brand industrial robots. The opening of the underlying technology plays a vital role in the improvement of robot performance indicators. Song Gaosheng believes that the servo drive is the core component of the robot, and the power semiconductors hidden in it play a key role in the performance of the servo drive. In the iterative upgrade of power semiconductor products, higher junction temperature and lower electromagnetic noise are its eternal pursuit. At present, Mitsubishi Electric's latest seventh-generation products have improved their junction temperature and electromagnetic noise performance, but they are far from enough. The strict material requirements of semiconductor products have led to a slower cost reduction, and noise control is still in iteration, which has become a challenge facing power semiconductors. Ji Shuting pointed out that the current technical bottleneck in the RV reducer industry is mainly accuracy retention and life issues. For Zhitong, these two hard bones have been gnawed down. The next problem is how to rapidly expand production and make the market accept us. Zhitong`s development goal is to keep up with foreign mainstream products until it leads the RV reducer market. Gui Xinfei said that as the application range of harmonic reducers becomes wider and wider, its application in harsh environments is facing challenges. How to make improvements in materials and processes so that the reducer can cope with various harsh working environments is a technical problem. Tang Weiwei said that the global semiconductor market is currently very competitive, and Bitmain has advanced chip manufacturing capabilities, 7nm, 5nm and even 3nm in the future. Performance and power consumption are the eternal pursuit of semiconductors, which can make the robot "brain" smarter. Miao Yuqun pointed out, "My idea is very simple for the breakthrough of the underlying technology. The first is "Tian Ji Horse Racing", to fully identify his own advantages; the second is to have a specialization in the technical industry and continue to do well in the depths. Own business; the third is to insist on cooperation and win-win, insist on doing everything, often do nothing well, just like Daru Technology, only focus on the polishing field."


In the industrial manufacturing field, because of stricter standard of industrial products art and harder to attract labor, it has become essential for the automation upgrading, especially in grinding polishing field, its trend is more obvious. However, in actual process, automation upgrading does not only mean in the equipment, but also should form know-how perfect solution for the whole industry, then can we energize factory to realize upgrading. Anyone who has been long in grinding polishing field all know that its producing art requirements are complicate, abrasive material, particle size, workpiece surface size discrepancy, touch area size, pressing magnitude, grinding angle, beat etc. factors all are possible to make effects to grinding effect and efficiency, which make it hard to realize manufacturing automation. Therefore, more factories are still using traditional manual grinding method. In a situation in which competitionness could be different with 1 percent producing efficiency improving, these factories are similarly desperate to improve efficiency and yield with the help of automation. But the fact is that they can not find the solution to help realize art effect, they have to stand and accept manual grinding hurts and risks. From this point, it has appeared obvious unmatched condition in grinding polishing field supplying end and demanding end. Grinding polishing requires higher for flexible control, operating speed and stability in the process, the professional degree of upstream manufacturers, deeply understanding for grinding art become thresholds that are hard for automation equipment integrators to step over, leading few integrators who are familiar with grinding polishing among these many automation integrators in market. The obvious application hurts and customers' strong demanding for realization of automation renovation, grinding polishing field has enough reason for manufacturers to excavate deeply. As to how to discover these rich branch markets, the key is at the technique ability and the market strategy. Labor or robot for grinding and polishing? With the precicer and better manufacturing pushing, eco-friendly requirement in policy, and factory itself developing need, manual as well as in robot operating has shown some limits, and can not satisfy increasing requirements. First, manual operating mainly relies on personal experience. The worker can flexibly deal with grinding polishing by their sight, touch, logical judge for any shape,size discrepant workpieces, which is the greatest advantage of manual grinding, the richer experience the worker has will lead higher efficiency and better surface effect. However, its disadvantages are also obvious. Manual grinding only can depend on feeling and experience, the worker can not measure how much force he imposes, neither can he keep the force output stable, thus it can not ensure the workpiece surface evenness and effect consistency; Uncertain manual force makes fluctuant productivity and yield. From health aspect, heavy dust, noisy sound, and high frequent vibrating from grinding machine will bring great threat to operator body health, which leads fewer and fewer grinding workers. Comparing with manual grinding, robot grinding can realize high efficiency and stable operating by programmed paths, helps enterprises improve producing effiency and yield, cuts down cost. In the condition of workpiece materials complexity and diversification, there are many workpiece forming arts, including sheet metal, stamping, forging, injection molding, CNC etc, because of material character and discrepancy of forming methods, most workpieces exist size errors, the only difference is the data size. Usually industrial robot is running precisely as the path which is adjusted well, the running path is fixed and error is very small, but if big tolerance appears on workpiece, or any positioning discrepancy happens, grinding effect will fluctuate a lot, what's worse, some areas are not reachable, or grinding excessively because of too big pressure, lead low yield, and can not realize mass production. Besides industrial robot, other expertised equipments also face such difficulties. Many enterprises in this field find this difficulty and try different solutions, like visual distinguishing, all kinds of floating structures etc. At present, most are researching robot combining with force sensor, through force sensor feeling and transmitting workpiece surface changing info, then adapt to workpiece surface changing by robot adjusting running path. Different from above solutions, Daru Technology (Suzhou) Co.,Ltd which is specialized in grinding and polishing has positioned its self as flexible and intelligent grinding system expert. For many years researching and developing, Daru has promoted flexible and intelligent grinding system, which can realize flexible control for force, initially adapt workpiece surface size changing in its running process; More importantly, instantly control force magnitude in a demanding range, can ensure workpiece surface effect even and consistent, improve yield and make it possible to realize factory automatic mass production. Daru general manager Yuqun Miao says, adding force sernsor to robot is indeed an effective way to strengthen robot flexibility, but it is mostly used in assembling and transferring of materials and so on; For grinding polishing application, it needs fast and repeating movement to realize even grinding effect, requires high for actuator instantaneity. This method has its limitation. Though it can also realize grinding effect by slow movement, work efficiency is relatively very low. The core of cultivating customer's habit---solve the hurts in this field. The complexity of grinding polishing art decides that it is hard to form deeply understanding and perceiving if there is no years of deeply grounding in field applications and customer scenes, it is just a blank promise to make values for customers. As the founder and general manager of Daru Tech-Yuqun Miao has been working in grinding field long for 16 years, his rich automation grinding polishing experience, and his team's deeply understanding for grinding art, equipment property, customer's real demanding.
