Description

Technical Field

[0001] The invention relates to the field of LED lamp bead production, and in particular to a coating device for LED lamp bead production. Background Art

[0002] LED lamp beads are PN junctions composed of P-type semiconductors and N-type semiconductors. They have unidirectional conductivity and can emit light under the action of appropriate voltage and current. This light source has the advantages of high efficiency, low energy consumption, long life, environmental protection and energy saving. In the production process of LED lamp beads, the LED lamp beads will be vulcanized and oxidized, which will cause blackening and darkening. In order to prevent this from happening, the LED lamp beads need to be coated with anti-sulfurization.

[0003] However, most of the current lamp bead coating devices require manual pushing of the lamp bead board to move during the coating process in order to continuously coat the lamp bead board, which consumes a lot of manpower and time, and leads to low efficiency in coating the lamp bead board with anti-sulfurization glue. In addition, the existing coating device has a single structure, which makes it inconvenient to effectively limit the lamp bead board during the lamp bead coating process, which easily causes the lamp bead board to shift, and it is difficult to evenly apply the anti-sulfurization glue, resulting in glue leakage and lack of glue on the surface of the lamp bead board, thereby resulting in poor effect of coating the lamp bead board with anti-sulfurization glue.
