Resin coating device and a resin coating method

摘要

In a resin coating which is used in the manufacture of an LED package which is made by covering an LED element with resin that includes fluorescent substance, a light-passing member (43) on which the resin (8) is test coated for light emission characteristic measurement is carried on a light-passing member carrying unit (41), a deviation between a measurement result obtained after the light emission characteristic of the light that the resin (8) emits, when an light source unit (45), which is placed above, emits excitation light which excites the fluorescent substance, and irradiates the excitation light from above to the resin (8) which is coated on the light-passing member (43), is measured and the light emission characteristic prescribed beforehand is obtained, and an appropriate resin coating quantity with which the resin should be coated on the LED element is derived for practical production based on the deviation.

1. A resin coating device which is used in an LED package manufacturing system for manufacturing an LED package made by covering an LED element mounted on a board with a resin that includes fluorescent substance, and which coats the resin to cover the LED element mounted on the board, the resin coating device comprising:
a resin coating unit which discharges a variable coating quantity of the resin, and coats the resin at any coating positions; a coating control unit which, by controlling the resin coating unit, makes a coating process for measurement in which the resin is test coated onto a light-passing member for light emission characteristic measurement and an appropriate resin coating quantity is determined with which the resin is coated onto the LED element, and a coating process for production in which the resin with the determined appropriate resin coating quantity is coated onto the LED element for practical production to be performed; a light-passing member carrying unit on which the light-passing member on which the resin is test coated in the coating process for measurement is carried; a light source unit which is placed above the light-passing member carrying unit, and emits excitation light to excite the fluorescent substance; a light emission characteristic measuring unit which receives from below the light-passing member the light that the resin emits when the excitation light is irradiated from above to the resin which is coated on the light-passing member, and measures the light emission characteristic of the light; a coating quantity deriving processor which calculates a deviation between a measurement result of the light emission characteristic measuring unit and a previously specified light emission characteristic, and determines the appropriate resin coating quantity based on the deviation; and a production performing processor which, by ordering the coating control unit with the appropriate resin coating quantity, makes the coating process for production in which the appropriate resin coating quantity of the resin is coated on the LED element to be performed.
