Comparison of robot and joint industrial robots with applications in machine tools

　1. Layout aspects
　　
Truss robot is generally located above the machine tool, the track is single, covers a small area. Joint robots are generally taken a pair of 2 or 1 to 3 (glyph layout), in order to ensure safety needs to carry out a full range of protection of the entire processing unit, and upside down walking robot because the cost is too high, the complex stability of the system is low rarely put into practical application, we do not focus on discussion.
　　
2. Human-machine collaboration
　　
Truss robot production line workers can monitor the processing process, the problem is eliminated quickly, sampling is convenient, human-machine collaboration is better.
　　
Due to the unpredictability of the movement trajectory of the joint robot, the production unit is completely closed in the actual production process workers can not participate in the production process, the production process of the unit silos, production equipment, robots for a series of monitoring and management, the system is huge and complex high cost.
　　
3. Efficiency (start-up rate)
　　
"On rate" industry to measure the stable production of equipment standards. The introduction of robot automatic up and down materials, in the actual production process of this blank quality stability, tool quality and life management needs to have higher requirements. Joint robot up and down material. The entire production process is unmanned, the management of the tool includes specific to which knife to do that size, whether the need for a knife supplement, the size of the knife, can only be determined by measuring the product size of the output, if this size has several knives involved, the production management challenge is greater, the system integration requirements are higher. Truss robot due to good human-machine collaboration, sampling, knife can be achieved at a low threshold.
　　
4. Cost
　　
Unit price, management and maintenance cost truss robot is generally lower than joint-type industrial robot, characterized by multi-online truss-type robot price is much cheaper than joint-type robot, and maintenance management costs are also low.
　　
Through the above simple comparison, it can be seen that, although the vertical multi-joint robot has a 3D space posture, positioning accuracy, easy to operate and other advantages in casting, handling, welding, system integration has been a wide range of applications. But in the machine tool up and down this a "simple" handling industry, by truss robot this simple structure, the movement track of a single "fool" defeated. In the transformation of machine tool automation production line, the choice of the most suitable is the most important. The simplicity of truss robot allows people to participate in the process of monitoring production, which is gradually replaced by unmanned people, which is actually more suitable for the existing production management methods of local enterprises more ground gas reality feasible.
