Abstract

The invention provides a manufacturing method of LED light bars. The method comprises the steps as follows: (1) circuit board units are produced, wherein each circuit board unit is formed by connecting a plurality of elongated LED substrate units side by side; (2) an electronic component is arranged on each LED substrate unit; (3) more than two circuit board units are connected end to end to form a connected circuit board; and the LED substrate units in end-to-end correspondence achieve electrical connection through connection pads to form a light bar substrate; (4) outgoing lines are welded at two ends of the connected circuit board; and two ends of each light bar substrate are connected with two outgoing lines; (5) the connected circuit board is placed into a groove; (6) glue is sprayed into the groove by a spray head assembly from the upper direction of the connected circuit board; (7) the glue is taken out after being flatly cast and solidified; and (8) the light bar substrate in the connected circuit board is cut and separated by cutting equipment to form the LED light bars. The manufacturing method of the LED light bars is simple in technology, high in production efficiency and low in cost.

Description

technical field [0001] The invention relates to the manufacture of LED light strips. Background technique [0002] LED flexible light strip (LED flexible light strip) has the characteristics of high brightness, long service life, energy saving and environmental protection, etc. It is widely used in the decorative lighting market, such as in signboards, subtitle advertisements, building outlines, indoor ceiling lighting, Lighting places such as interior decoration of automobile body. [0003] The manufacturing method of the traditional LED light strip: first produce the whole circuit board, then cut the circuit board out of the light strip substrate unit, then connect the light strip substrate unit end to end to form the light strip substrate, and finally dispensing or dispensing the light strip substrate. Set of rubber tubes to form LED strips. Such as Chinese patent publication number is 101440918 a kind of manufacturing method of LED flexible waterproof light-emitting st...
