Abstract

The invention discloses a curing time sequence control system in an LED encapsulation. The system comprises a controller, an oven, a transmission unit, a plurality of temperature sensors and timers, the controller is connected with the oven, the transmission unit and the temperature sensors, the oven comprises a first temperature zone, a second temperature zone and a third temperature zone which are connected in sequence, one temperature sensor and one timer are arranged in each temperature zone, the transmission unit comprises a first guide rail, a second guide rail and a third guide rail arranged in sequence, each temperature sensor detects temperature information of the corresponding temperature zone and transmits the temperature information to the controller, each timer is used for timing baking time, and the controller controls heating systems and the guide rails in all the temperature zones to work or stop according to the temperature information and the baking time. By setting of different temperature zone lengths and time-sharing control, utilization rate of the system is increased.

Description

technical field [0001] The invention belongs to the field of LED applications, and in particular relates to a curing sequence control system in LED packaging. Background technique [0002] China is a big country in LED packaging. It is estimated that 80% of the world's LED device packaging is concentrated in China, distributed in various US-funded, Taiwan-funded, Hong Kong-funded and domestic-funded packaging companies. [0003] In the past five years, foreign-funded LED packaging companies have continued to relocate to the mainland, while domestic-funded packaging companies have continued to grow and develop, and their technologies have continued to mature and innovate. In the field of low-end LED device packaging, Chinese LED packaging companies have a relatively high market share. In the field of high-end LED device packaging, some Chinese companies have made major breakthroughs. With the continuous maturity of technology and the accumulation of brand reputation, Chinese...
