RGB-LED full-automatic fluorescent powder glue high-speed intelligent coating device and method

Abstract

The invention discloses a RGB-LED full-automatic fluorescent powder glue high-speed intelligent coating device, the intelligent coating device includes a lower computer and an upper computer control system; the lower computer comprises a machine frame, a fluorescent powder glue feeding mechanism, a conveying mechanism, a coating movement module, a fluorescent powder glue thickness measuring mechanism, and a lower computer controller, the fluorescent powder glue feeding mechanism presses the mixed fluorescent powder glue into a spray head in the coating movement module through air pressure, theconveying mechanism conveys the chip array and fixes the chip array on the coating position, and the spraying head on the coating movement module is used for coating the chip at the coating position,the fluorescent powder glue thickness measuring mechanism is used for detecting the coating thickness of the current chip array, and the lower computer controller is connected with the upper computercontrol system. The device is high in automation degree, and has the functions of coating feedback control and online setting control parameters, the purpose of high-precision control on the coatingthickness of the fluorescent powder glue can be achieved, and the RGB-LED coating precision and coating efficiency of the LED can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of automatic coating of LED fluorescent powder glue, in particular to a high-speed intelligent coating equipment and method for three primary colors RGB-LED automatic fluorescent powder glue. Background technique [0002] Light-emitting diode (LED) is a new type of semiconductor all-solid-state lighting source. Compared with traditional lighting technology, this new type of light source has obvious advantages such as high efficiency and energy saving, long life, small size, green environmental protection, and safe use, and is recognized as the first choice for future lighting sources. At present, large-inch liquid crystal displays have been widely used in televisions and computer screens. Their backlights still use the traditional cold cathode fluorescent tube (Cold Cathode Fluorescent Lamp, CCFL), which contains red, green, and blue lights. Frequency of. In terms of service life, the service life of cold ...
