AI Technical Summary
Technical Problem
Existing methods for applying high-viscosity materials face issues with thread cutting reliability, leading to material accumulation around the nozzle tip or on the ejection receiving medium.
Method used
An application device that includes a syringe with a nozzle, a metal support part, a power source, and a control device, which performs processes to eject, compress, and separate the high-viscosity material from the nozzle, utilizing electrostatic forces and mechanical movement to enhance cutting reliability.
Benefits of technology
Improves the reliability of cutting high-viscosity material threads by reducing surface area and increasing surface tension, minimizing residual material, and preventing string formation.

Abstract
To provide a coating device that can improve reliability on cutting a string of a high-viscosity substance.SOLUTION: A coating device comprises: a support part made of metal that supports a medium to be discharged; a syringe having, at a tip thereof, a nozzle for coating the medium to be discharged, with a high-viscosity material; a power supply that applies a voltage to a space between the nozzle and the support part; a driving part that moves any one of the syringe, the support part as well as the syringe and the support part so that the nozzle relatively gets closer to the medium to be discharged or gets away from the medium to be discharged; and a control device. The control device executes: a first process in which the nozzle discharges the high-viscosity material to the medium to be discharged in a state where the power supply applies a voltage to the space between the nozzle and the support part; a second process in which the driving part makes the support part get closer to the nozzle so that the nozzle compresses the high-viscosity material on the medium to be discharged, after the first process is completed; and a third process in which the driving part makes the support part get away from the nozzle, after the second process is completed.SELECTED DRAWING: Figure 3
