Description

Technical Field

[0002] Light bar is a kind of lighting product in LED series, which is characterized by cold light source, low heat generation, high efficiency and energy saving. Flexible LED light bar adopts FPC as assembly circuit board, high brightness LED packaged with SMD as light source, 3 lights as a unit, and 50 cm as a large length unit for assembly and bonding.

[0003] At present, when dispensing glue on LED light strips, in order to improve efficiency, two single dispensing machines are often used in succession. After the first dispensing line on the LED light strip is dispensing back and forth, the glue is stopped and then moved to the second line. After the second line is dispensing back and forth, the glue is stopped and moved to the third line. This is repeated until the fifth line is finished and the conveyor belt moves forward to the second device to complete the dispensing of the sixth to tenth lines. Using two dispensing machines to work not only increases energy consumption, but also takes a long time to dispense glue on a single line, and the dispensing efficiency of the light strip is limited.
