Embodiment Construction

[0022] The present invention will be described in detail below by taking preferred embodiments as examples.

[0023] However, those skilled in the art should understand that the following are only examples and descriptions of some preferred implementations, and other similar or equivalent implementations can also be used to implement the present invention.

[0024] Production of brackets

[0025] Cut out the entire roll of copper sheet material with a well-designed mold on Hongrui 45T high-speed punching machine to punch out the entire roll of LED bracket prototype circuit, such as positive metal 1.1 and negative metal 1.2 for packaging LED chips .

[0026] Then use Ogilvy's electroplating line to selectively silver-plate the surfaces of the positive metal 1.1 and the negative metal 1.2 in the prototype circuit of the LED bracket.

[0027] Use the well-designed injection mold to inject on the Nissei injection molding machine. The heat-resistant insulating resin 2 formed by i...

Abstract

The invention relates to an LED patch lamp beads only packaged by lens glue and a manufacturing method thereof. The method particularly comprises the following steps: manufacturing a continuous row ofcup-shaped brackets containing a plurality of LED patch lamps, bonding LED chips on positive and negative electrodes of the cup bottoms of the brackets in a die bonding manner, injecting lens glue into each manufactured continuous row of mold cups containing a plurality of cup-shaped lens molds, immersing the LEDs packaged with the chips into the glue in the mold cups with the cup openings facingdownwards, immersing the outer wall of each cup into the glue, enabling each bracket cup to correspond to one mold cup, enabling each LED cup opening and the inside and outside of each cup to be immersed into the glue, heating to solidify the glue into transparent lenses, firmly combining the lenses at the LED cup openings, then pulling out the row of LEDs with the lenses from the mold cup, and cutting the row of LEDs into single patch lamps with transparent lenses. The manufacturing method of the LED patch lamp beads is simple, the LED patch lamp beads are manufactured through connecting pieces at the same time, the efficiency is very high, and the cost is very low.

Description

technical field [0001] The invention relates to the field of LED applications, in particular to an LED patch lamp bead packaged only with lens glue and a manufacturing method thereof. Background technique [0002] Now there are several methods for making lamp beads with lenses. One method is to use a top mold to make the top rubber mold on the lamp beads on the top mold machine to form a lens. This method is very expensive. [0003] Another method is to make the lenses first, and then use glue to glue the lenses to the lamp beads one by one, which is very inefficient and expensive. [0004] In order to overcome the above disadvantages, the present invention adopts the chip lamp bracket to solidify the crystal and wire the chip, then insert the bracket cup upside down into the lens glue of the lens mold cup, after curing, it will come out from the mold cup, and the It has become a SMD lamp bead with a lens, the production method is simple, and the production is made at the s...
