Since the brackets of the above-mentioned thermosetting plastic light-emitting diodes are all fabricated in a chip form, the light-emitting diode brackets of the thermosetting plastic cannot be automatically produced, which reduces production efficiency and throughput, and is used. The large number of people also makes the production time longer, which greatly increases the production cost.

Therefore, the main object of the present invention is to solve the conventional deficiency, and the present invention will be thermoset. The manufacturing method of the plastic light-emitting diode is adopted in the form of a roll, so that the bracket of the thermosetting plastic light-emitting diode can be automatically produced to improve the production efficiency and the production amount, and the manpower is saved, and the production time is shortened. Reduce production costs.

In order to achieve the above object, the present invention provides a method for manufacturing a bracket for a thermosetting plastic light-emitting diode, comprising: preparing a roll of metal material; processing the metal material by stamping or etching to form a stent strip; processing The completed stent strip is sent for electroplating; the electroplated stent strip is placed in a mold for sealing, so that a plurality of pedestals are formed on the stent strip; and the encapsulant is completed to form a scaffold having a plurality of pedestals The strip is sent to the oven for baking; then the bracket strip with the plurality of pedestals is baked and cut into a single piece of the web.

In order to achieve the above object, the present invention provides a method for fabricating a stent for a thermosetting plastic light-emitting diode, comprising: preparing a roll of metal material; processing the metal material by stamping or etching to form a stent strip; The processed stent strip is sent for electroplating treatment; the electroplated stent strip is placed in a mold for sealing, so that a plurality of pedestals are formed on the stent strip; the sealant is formed with a plurality of pedestal stent materials The strip is cut into a single piece of the web; the sheet is then placed in an oven for baking.

The technical content and detailed description of the present invention are described below with reference to the following drawings: Please refer to the second figure, which is a schematic flow chart of the method for manufacturing the bracket of the thermosetting plastic light-emitting diode of the present invention. Please also refer to the schematic diagram of the semi-finished structure of the third to sixth figures. As shown in the figure: In the method for manufacturing the bracket of the thermosetting plastic light-emitting diode of the present invention, first, as in step 100, a roll of metal material 1 (as shown in the third figure) is prepared.

In step 102, the roll of metal material 1 is subjected to a stamping or etching process to form a carrier tape 2 having a plurality of carrier bodies (cups) 21 (as shown in the fourth figure).

In step 104, the processed material strip 2 is sent to an electroplating machine for electroplating.

Step 106, the electroplated stent strip 2 is placed in the mold, and the carrier 21 on the stent strip 2 is sealed with a thermosetting plastic, and a base 3 is formed on the carrier 21 ( As shown in the fifth figure).
