Description

Technical Field

[0001] The utility model relates to the field of glue dispensing mechanisms, in particular to a light emitting diode glue dispensing mechanism. Background Art

[0002] A light-emitting diode is an optoelectronic device that generates light using the principle of electroluminescence. It contains a pn junction. When current passes through the junction, the current generates electrons and holes at the heterojunction. When the two recombine, they release an integer multiple of the photon energy, thereby emitting light. Light-emitting diodes have many advantages, such as small size, low operating voltage, low operating current, uniform and stable light emission, fast response speed, and long life. They can be driven and lit by various DC, AC, pulse and other power sources, and the color of the light is related to the wavelength of the light, which in turn depends on the semiconductor material used to manufacture the light-emitting diode.

[0003] LED lamp is a common lighting device that uses light-emitting diodes as light sources. The emergence of LED lamps has greatly changed the traditional lighting industry and has become the mainstream choice for modern lighting. LED lamps usually have several light-emitting diodes evenly arranged on the substrate. The light-emitting diodes are connected to the substrate, and adjacent light-emitting diodes can be connected in series or in parallel. The advantage of the series connection method is that the power supply is more energy-saving and the brightness of the lamp beads can be higher at the same voltage, but when one of the lamp beads is damaged, the entire circuit will be affected; the advantage of the parallel connection method is that there is no connection between the lamp beads, so the brightness, current, voltage and other parameters can be controlled separately, but it is necessary to ensure that the current and voltage of all LEDs are the same, otherwise the brightness between the LEDs will be uneven. In order to fix the connection between the light-emitting diode and the substrate, a dispensing mechanism is usually used to glue the light-emitting diode to the substrate.

[0004] The existing dispensing mechanisms are of two types: single-head and multi-head. The distance between the dispensing heads of the multi-head dispensing mechanism is often fixed, and it can only dispense glue to LEDs with one spacing. It cannot be adjusted in real time according to the actual position of the LEDs. The scope of application is small. When producing another density of LEDs, the dispensing heads can only be removed from the machine body and then the spacing can be readjusted, which is inconvenient and troublesome.
