Reproduction of thin film by R technology. Plating-like coating is realized.

　The growing demand for plating is not just for design, but also for parts that combine functionality, such as communications, making it important to reproduce metal coatings that meet functional requirements.
　Therefore, Takubo Engineering's original thin-film coating technology with revolving coating, "R technology," replicates it.
　Automatic spray guns, robots, controllers, conveyors, precision paint feeders syringe pumps, software SWANIST, etc. are controlled by advanced collaborative technology. By accurately reproducing the coating conditions set by SWANIST, a high-quality thin-film coating film can be completed at a low cost. The plating-like coating is achieved by digital coating with numerical control.

Plating-like coating realized by technology cultivated in revolving coating In. Mirror Coating System

Thin-film coating with R technology is the key to plating-like coating

　Indium coating is a film that combines functionality, such as millimeter wave permeability, in addition to design properties. It is important to realize a thin film to take advantage of this feature. The R technology of spray painting and thin-film multiple coating realizes the film.

R technology Indium coating process

　The painting process of the In. Mirror Coating System consists of three coats: under, indium, and top. The plating-like coating is made feasible by the indium coating in the middle coat. Thin, discontinuous films are formed to perform functions such as transmitting millimeter waves. R technology makes it possible to mass-produce it in sprays.
　The robot coats the workpiece while revolving it forward and backward, reproducing thin-film multiple coating. R technology numerically controls all condition settings from robot to spray, rotation speed, etc. It realizes thin-film digital coating.

R technology　 Thin-film multiple coating

　The workpiece is mounted on a circular jig and the transfer device of the robot system with rotation mechanism rotates forward and reverse.
　The robot repeatedly applies multiple thin-film coatings to the rotating workpiece.

R technology　 Condition setting

• Coat large areas of the workpiece with a wider pattern　/　Coat a narrower pattern on the part that hits the back side of the workpiece A series of condition settings are easily controlled by setting teaching conditions. You can freely change the pattern as if you were editing a video.
  　

  

• 　In revolving coating, the work is distributed between the revolving workpiece and the robot, simplifying the robot's movements and reducing robot costs by requiring only four axes on the robot itself. In addition, the fewer the number of axes, the simpler the robot control (teaching) and the easier the condition setting work becomes.
  
  

  

• 　The features of revolving coating are as follows.
  ・Cooperative work between workpiece and robot
  ・Robot movements are simple and easy to teach.
  ・Coating can be done by 4-axis robot
  ・No programming of the robot is required but can be done by inputting SWANIST's numerical values (setting conditions)
  

Precise dosing of paint　Paint supply system syringe pump

　A paint feeder for spray painting systems that simultaneously solves quality, cost, and environmental issues is essential. A syringe pump system is systematized to control the paint ultra-precisely and deliver the required amount to the gun precisely as required.

Flexible film thickness control. Software to simplify condition setting

　Controlled by “SWANIST” software that reproduces thin-film coating. SWANIST is an assistant software program that provides sophisticated programmatic control of painting equipment. This software simplifies the setting of coating conditions and quantifies and manages the coating process.

　Free from the heavy workload of the spray man. “R technology”, which makes maximum use of the robot's strengths of unrelaxed motion and repetitive accuracy to revolving coating of workpieces, aims to standardize robot coating. Good thin-film coating finish, high productivity, low paint usage, and significant reduction of VOCs are possible. “R technology," which uses sophisticated applications to control the peripherals required for coating.
