Abstract

The invention discloses a fully-automatic LED phosphor coating apparatus and a control method thereof. The phosphor coating apparatus comprises a frame, a main control box and an industrial control computer main engine are fixed below the frame, the top end of the frame is provided with an XYZ-axial motion platform, a tray dragging mechanism, a nozzle control box, a waste box and a cleaning sponge, a control circuit is installed in the main control box, the Z-axial moving sliding block of the XYZ-axial motion platform is provided with a spraying device and an image acquisition device, an industrial control computer keyboard and an industrial control computer display screen are fixed over the nozzle control box, and the control circuit and the image acquisition device are respectively connected with the industrial control computer main engine. The apparatus has a simple and compact structure, and the control method is also used to improve the execution efficiency of system resources, so the fully-automatic material feeding, blanking and LED phosphor coating of an LED support can be completed, and the problems of low efficiency, non-uniform phosphor coating surface and the like of manual material feeding can be solved.

Description

technical field [0001] The invention relates to the technical field of LED production equipment in optical-mechanical-electrical integration, in particular to fully automatic LED fluorescent powder coating equipment and a control method thereof. [0002] technical background [0003] Due to the production method of "blue light chip + YAG phosphor powder" to produce white light LED, its cost is the lowest, and its practicability is strong, which has become the mainstream of current market products. Applying sapphire-based LED chips to the field of semiconductor lighting requires complex packaging and manufacturing processes, including die bonding, bonding, phosphor coating, plastic molding, spectroscopic and color separation, and testing, sorting, and taping. The blue light emitted by the LED is converted to white light. As one of the key processes to realize the conversion of LED blue light to white light, phosphor coating directly affects LED luminous efficiency and light...
