专利汇可以提供Coating device for braun tube panel专利检索,专利查询,专利分析的服务。并且PURPOSE: To enhance the yield and the quality for coating of the Braun tube by reducing the defect occurrence with use of the inductive motor and also securing smooth rotations.
CONSTITUTION: Holding cylinder 7 mounted with shaft 8 with panel chuck 9 provided at one end is installed to carriage car 2, and shaft 8 is linked to the axle of 3-phase inductive motor 20 which is attached to one end of cylinder 7. At the same time, frequency control unit 25 is provided to board 2 to control the revolution number of motor 20 to be then supplied to motor 20 via contact 21 and power supply rail 23. Thus, panel P is rotated with about 10rpm at rail 23, for example, to drop down the fluorescent slurry or the like onto the inner surface; the slurry is spread at the next rail in about 300rpm; and the slurry is dried at the subsequent rail in about 70rmp. As a result, no defect is caused by the abrasion filings of the brush, thus enhancing both the quality and the yield for the panel coating by securing the smooth variation of the revolution number.
