Abstract:
1. A resin coating device that coats a resin over an LED element mounted on a substrate for use in an LED package manufacturing system that manufactures an LED package in which the LED element mounted on the substrate is covered with the resin containing a phosphor therein, the resin coating device comprising: a resin coating unit that discharges the resin with a variable coating amount to coat the resin at an arbitrary position to be coated; a coating control unit that executes measurement coating processing for trial-coating a translucent member reeled off by a recovery reel while being reeled out of a supply reel with a resin for measurement of a light emission characteristic while controlling the resin coating unit, and production coating processing for coating the resin on the LED element for actual production; a light source unit that emits an excitation light that excites the phosphor; a translucent member placement portion on which the translucent member that has been trial-coated with the resin in the measurement coating processing is placed; a light emission characteristic measurement unit that measures the light emission characteristic of a light emitted from the resin by irradiating the resin coated on the translucent member with the excitation light emitted from the light source unit; a coating amount derivation processing unit that derives an appropriate resin coating amount of the resin to be coated on the LED element for the actual production on the basis of a measurement result of the light emission characteristic measurement unit and a light emission characteristic specified in advance; and a production execution processing unit that instructs the coating control unit about the appropriate resin coating amount to execute the production coating processing for coating the appropriate resin coating amount of resin on the LED element, wherein the supply reel and the recovery reel are arranged on a same shaft member, and when the translucent member is moved forward by actuation of a drive source for advancing the translucent member, one of the supply reel and the recovery reel is rotated while being pulled by the translucent member to reel out the translucent member, and the other reel is rotationally driven through a torque limiter disposed on the shaft member to reel off the translucent member.
