From April 12 to 17, the 17th China International Machine Tool Exhibition (CIMT) took place at the Beijing International Exhibition Center (New Hall). During this exhibition, Feixi Technology and German Xiongke Company (Stand: E1 A301) presented the flexible automation solution for the finish and loading and unloading of machine tools for the first time.
Today, when intelligent manufacturing has become the dominant direction of manufacturing development, the treatment of machine tools is increasingly showing the trend of rapid, precise and intelligent. However, the traditional automation and loading and unloading production lines made up of machine tools, precision lights and industrial robots are generally confronted with a problem: the assembly difference between the Precision devices and the parts is much smaller than the repeated positioning accuracy of traditional industrial robots, which gives great results to the uncertainty of assembly and hidden dangers consumables. The question of whether the flexibility of the loading and unloading finish can be resolved is crucial for improving the efficiency and the complete development of the machine tool industry.
Challenges in machine tool automation
Currently, common precision pliers in the treatment of machine tools include hydraulic nucleus trees, ornaments, tool holders, visors, etc. Among them, ornaments as general lighting are widely used in tightening parts such as trees and discs, but during the automatic loading and unloading process, the tightening force and the central gap between the robot and The chuck are easily caused by ineffective assembly or the part is damaged.
Hydraulic expansion devices represented by hydraulic nucleus trees have fine rotation accuracy (generally≤0.003 mm), can effectively solve the deformation of parts with thin walls and are frequently used in fine processing operations. , tightening for 15 mm gears, the clearance in one side is 0.0225 mm), which is much lower than the accumulated errors of robots and hydraulic lights mainly depending on the positioning and is extremely difficult to assemble. In response to this problem, there are currently two consumer solutions on the market:
Lateral assembly: Suitable for double-pin machine tools. This type of solution has high requirements for machine tools, the complex overall configuration, long loading time and high cost.
Vertical assembly: mainly uses floating tools and is responsible for chamfers between lighting and rooms. These solutions are inevitable to scratch the surface of the room and require additional tools and processes.
As can be seen from the above, the traditional unloading and automation solution cannot solve the problem of correspondence of precision lights and parts, and will bring drawbacks such as low yield assembly, part loss and high cost.
Adaptive robot+ AGV / AMR + Xiong tool combination to improve the flexibility of loading and unloading of machine tools
Intelligent Robot CompanyFeixi technologyWith the well-known world-tool luminaire supplier from the worldGerman Shink CompanyJoint launchFlexible automation solution for loading and unloading machine toolsCan adapt automatically as an assembly gap between precision lights and parts, help customers complete the flexible and stable loading and unloading automated machine tools, and obtain the optimization of the line production and overall cost.
The plan mainly includes:FEIXI compound robot（Rizon Dawn corresponds to the AGV / AMR platform) andXiongke tool combination(Lighting, quick change of zero points, robotic hands, robotic accessories, etc.).
Adaptive robots combine control of industrial quality force, machine vision and artificial intelligence technology, overthrow the traditional position focused on position control, can adapt to uncertain environments and to be completed Complex tasks through coordination of eye-hand like human hands. Dawn is compatible with various third partiesThe AGV / AMR platform allows a system to take care of several machine tools and can be deployed on the site without modifying the existing arrangement of the production line; With agile force.
When it really does work, the plan generally takes only one/ Two arms and double jaws, the adaptive robot equipped on AGV / AMR provides a force control resolution of 0.1 N at the end and a force of force control of 1 kHz. Reach compensation for position error in millimeters, in the end, on the basis of the guarantee that the surface of the part is not scratched, the effectiveness of beat is improved and the level of precision of the level level “of the wire” (0.01 mm) of the light (tree of the hydraulic nucleus, chuck, etc.) and the part is completed effectively.
