Bottlenecks In The Development Of Core Robot Components: The Love Pain Of Robot Parts Made In China

In May 2015, The State Council Issued The "Made In China 2025" Notice, Which Is The First Ten-Year Action Program For China To Implement The Manufacturing Power Strategy. The Main Contradiction Of Made In China 2025 Lies In Intelligent Manufacturing. The Main Contradiction Of Intelligent Manufacturing Lies In Industrial Robots, The Main Contradiction Of Industrial Robots Lies In Upstream Core Components, Especially Servo Systems, Control Systems Reducers. Today, Huiwen Zhizao Would Like To Take Reducers As An Example To Talk About The Love Pain Of Core Components In Made In China.

Going Back To The Source, The Realization Of "Made In China 2025" Must First Realize The Mass Production Of Intelligent Industrial Robots. However, The Core Components Of Industrial Robots Have Become A Hindrance. On The One Hand, There Is The Strong Demand For Components "Manufacturing Powers". On The Other Hand, There Is The Heavy Reliance Of "Manufacturing Powers" That Have Yet Taken Shape On Imported Components, The Resulting High Costs. Among The Core Components Servo Systems, Control Systems Reducers, Reducers Account For The Largest Share Of Procurement Costs (35%). The Import Volume Of The Three Core Components Accounts For More Than 75% Of The Total Purchase Volume.

1. Aizhi Reducer: One Of The Keys To Precision Manufacturing , With Large Increasing Market Demand

The Reducer Is The Core Component Of The Robot, Which Is Equivalent To The Joints Of The Human Body. It Is A Precise Power Transmission Mechanism, Its Main Function Is To Reduce The Speed Increase The Torque.

China's Demand For Industrial Robot Parts Ranks First In The World, It Is Increasing Year By Year. In 2016, The Global Sales Of Industrial Robots Reached 294,000 Units, Of Which China Sold 90,000 Units, Accounting For 30% Of The Global Demand. China Industry Information Network Predicts That The Sales Growth Rate Of Industrial Robots In China Will Be Around 20% 2017 To 2020, An Average Industrial Robot Needs To Be Equipped With 5 Reducers/Servo Motors 1 Control System. Based On This Reasoning, The Demand For Precision Reducers/Servo Motors For Domestic Industrial Robots In 2020 Will Be Nearly 780,000 Sets.

There Are Two Most Commonly Used Precision Reducers, RV Reducer (60%) Harmonic Reducer (15%). These Two Types Of Reducers Are Monopolized By Japan's Nabtesco Hamonica Drive Respectively. Harmonic Reducer Is Suitable For Robots Below 20 Kg. With The Increase Of Use Time, Harmonic Reducer Will Produce Certain Deformation Its Efficiency Will Be Weakened. RV Reducer Is Suitable For Robots Above 20 Kg. Compared With Harmonic Reducer, It Has Better Performance, But It Is More Difficult To Manufacture More Expensive. The Principle Of RV Reducer Is More Complicated Than Other Types Of Reducers. It Has A Two-Stage Transmission Device-The First Stage Involute Cylindrical Gear Planetary Reduction Mechanism + The Second Stage Cycloidal Pinwheel Planetary Reduction Mechanism. The Complex Structure Provides A Guarantee For Its Accuracy Durability.

2. Painful Reducer: High Cost Due To Reliance On Imports, Backward Technology Difficulty In Mass Production

Core Components Are Extremely Dependent On Imports. The Import Volume Of Servo Systems, Control Systems Reducers Reached 80%, 80% 75% Respectively. Domestic Enterprises Have Weak Bargaining Power At Present, The Price Of Purchasing Reducers Is 2 To 5 Times That Of Foreign Enterprises, Which Ultimately Causes Reducers To Account For 30% Of The Cost Of Industrial Robots. The Key Reason For The Above Phenomenon Lies In Technology.

RV Reducers Use A Positioning Structure, Which Can Improve The Local Rigidity Positioning Stability Of The Workpiece, But At The Same Time It May Cause Positioning Interference, Deformation Of The Workpiece Positioning Elements, Increased Errors. Therefore, The Manufacturing Of RV Reducers Has Very High Requirements For Processing Accuracy Matching, Which Are Basically At The Μm Level. The Figure Below Shows The Various Parts Of The RV Reducer After Its "Joints" Are Disassembled.

Nabtesco Hamonica Drive, Two Japanese Companies, Both Started To Invest In The Research Development Of Machine Manufacturing In The 1950s, While China Lagged Behind By Several Decades. Although Some Companies Have Been Able To Manufacture Core Components With Comparable Technical Levels In Recent Years, It Is Difficult To Guarantee The Service Life Of The Machines. This Is Also Related To The Precision When Manufacturing Robots. In Order To Achieve A Perfect Match, The Japanese Research Team Has Been Adjusting The Material Ratio Bit By Bit In The Laboratory Constantly Conducting Comparative Experiments. For Chinese Technology To Reach The Same Level, First Of All, It Requires The Calmness Of Craftsmen, Secondly, It Requires The Accumulation Of Time. If The Precision Is Appropriate, The Robot Will Be More Easily Worn. Therefore, Although Domestic Robots Can Be Comparable To International Ones When They Leave The Factory, Their Performance Will Decline After A Period Of Time. In Addition, Due To The High Cost Of Machine Tools For Producing Core Components, Domestic Parts Have Been Fully Mass-Produced. The Profit Selling Robots Is Difficult To Make Up For The Investment In Procurement Costs, Robot Manufacturers Do Have More Funds To Inject Into Technology Research Development. This Has Created A Painful Vicious Cycle Of "Insufficient R&D Funds -> Technical Standards -> Poor Sales -> Inability To Mass Produce -> High Manufacturing Costs -> Insufficient R&D Funds".

The Situation Can Be Even Worse. Fascinated By The Strong Domestic Market Demand, Foreign Robot Manufacturers Have Entered China Actively Deployed In The Yangtze River Delta. In Response To The Newly Emerging Domestic Brands, Foreign Manufacturers Have Adopted Price Cuts To Further Weaken The Market Competitiveness Of Domestic Robots.

3. Policy Research Development Work In Tandem To See Through The Mundane World Escape The Cycle Of Reincarnation

The National Policy Support For The Robotics Industry Can Be Said To Be Very Good——

The 2012 "12th Five-Year Plan For The Development Of National Strategic Emerging Industries" Proposed To Focus On The Development Of "Intelligent Manufacturing Equipment Industry";

In 2013, The Ministry Of Industry Information Technology Issued The Guiding Opinions On Promoting The Development Of The Industrial Robot Industry, Which Put Forward The Important Position Of Developing Industrial Robots;

In 2015, The Ministry Of Industry Information Technology Issued The "Notice On Launching The 2015 Intelligent Manufacturing Pilot Demonstration Special Action", Proposing To Invest More Than 11 Billion Yuan In 94 Demonstration Projects, Raising Support The Policy Level To Financial Support;

2015 "Made In China 2025" Established Intelligent Manufacturing As The "Main Direction" Of Made In China 2025...

Under The Strong Policy Push, Many Places Have Planned Robot Industrial Parks. However, The Number Scale Of Enterprises In The Industrial Parks Are Very Small, Making It Difficult To Form A Clustering Advantage. There Are Phenomena Of Blindness Duplication Of Construction. The "White Paper On The Development Of China's Robot Industry (2016 Edition)" Released By The China Academy Of Information Communications Technology Of The Ministry Of Industry Information Technology Puts Forward The Following Five Suggestions:

1. Improve The Policy Support System

2. Increase Technology Research Development Efforts

3. Carry Out Demonstration Applications In Depth

4. Focus On Breakthroughs In Key Products

5. Strengthen The Construction Of Talent Team
