Patent ID: 8505189

Claim:
A manufacturing apparatus for manufacturing a backlight unit, comprising: a feed mechanism configured to arrange a plurality of light-emitting diodes in a row; a testing mechanism having a testing module and a disposal module, wherein the testing module is configured to test the function of the light-emitting diodes, wherein the disposal module is configured to discharge the light-emitting diodes that do not pass the test of the test module; a first feed rail connecting the feed mechanism and the testing mechanism, wherein the first feed rail is configured to transfer the light-emitting diodes from the feed mechanism to the testing mechanism; an attachment mechanism having a guiding feeder and a fixing device; and a second feed rail connecting the testing mechanism and the attachment mechanism, wherein the second feed rail is configured to transfer the light-emitting diodes, that passed the test of the test module, from the testing mechanism to the guiding feeder, wherein the guiding feeder is configured to arrange the light-emitting diodes, that passed the test of the test module, to align a circuit board, and wherein the fixing device is configured to bond the light-emitting diodes, that passed the test of the test module, to the circuit board.
