LED package manufacturing system and resin coating method in LED package manufacturing system

A resin coating method in an LED package manufacturing system that manufactures an LED package in which an LED element mounted on a substrate is covered with a resin containing a phosphor therein, in which the resin is coated on a plurality of LED elements mounted on the substrate by the component mounting device, the LED package manufacturing system including:

• a component mounting device that mounts the plurality of LED elements on the substrate;
• an element characteristic information providing unit providing information obtained by measuring light emitting characteristics of the plurality of LED elements including a light emitting wavelength in advance, individually, as element characteristic information;
• a resin information providing unit providing information associating an appropriate resin coating amount of the resin for obtaining the LED package having specified light emitting characteristics with the element characteristic information, as resin coating information;
• a map data creating unit creating map data associating mounting position information indicative of positions of the LED elements mounted by the component mounting device on the substrate with the element characteristic information on the LED elements for each substrate;
• and a resin coating device that coats the resin of the appropriate resin coating amount for providing regular light emitting characteristics required for a completed product on the respective LED elements mounted on the substrate, on the basis of the map data and the resin coating information, the resin coating method comprising:
• a measurement coating step of coating the resin on a translucent member as light emitting characteristic measurement on trial by a resin discharge unit that discharges the resin of a variable coating amount;
• a translucent member mounting step, performed after the measurement coating step, of mounting the translucent member coated with the resin on trial on a translucent member mounting unit having a light source unit which emits an excitation light for exciting the phosphor;
• a light emitting characteristic measuring step, performed after the translucent member mounting step, of irradiating the resin coated on the translucent member with the excitation light emitted from the light source unit to measure the light emitting characteristics of the light emitted by the resin;
• a coating amount derivation processing step, performed after the light emitting characteristic measuring step, of obtaining a deviation between a measurement result in the light emitting characteristic measurement step and the light emitting characteristic specified in advance, and correcting the appropriate resin coating amount on the basis of the deviation to derive an appropriate resin coating amount for real production to be coated on the LED elements;
• and
• a production executing step, performed after the coating amount derivation processing step, of instructing a coating control unit that controls the resin discharge unit on the derived appropriate resin coating amount to execute the production coating processing of coating the resin of the appropriate resin coating amount on the LED elements.
