Embodiment

[0027] A high-power LED integrated chip junction temperature high-speed automatic detection device, comprising a polyvinyl chloride sliding guide 1, a chain 2, a production line chain rail motor controller 25, a production line chain rail motor driver 26, a production line chain rail motor 27, and an unpowered corner chain The slide rail automatic production line composed of the wheel 31, the power corner sprocket 30, and the production line assembly car 6. The computer and the production line chain rail motor controller 25 program jointly complete the control of the production line sequence and step sequence. The invention adopts the running mode of the sprocket and the sliding rail, and the assembly vehicle of the production line is fixed on the chain pendant, and is driven by the chain to travel. Two swivel wheels are installed under the assembly car on the production line to overcome the speed difference when cornering. The sprocket method is adopted at the 90° corner of ...

The automatic detection apparatus includes a slide guide rail production line driven by a stepping motor controlled by a computer program and a triaxial infrared temperature imaging tester, the slide guide rail production line driven by the stepping motor includes a slide guide rail, a chain, a production line chain rail motor controller, a production line chain rail motor driver, a production line chain rail motor, a nonmotile corner sprocket wheel, a power corner sprocket wheel, and a production line assembling vehicle, the triaxial infrared temperature imaging tester includes a stepping motor controller, a D-axis stepping motor driver, a D-axis stepping motor, a D-axis screw rod, a D-axis slide unit, a Y-axis stepping motor driver, a Y-axis stepping motor, a Y-axis screw rod, a Y-axis slide unit, an infrared temperature imaging instrument, and a limiting sensor. The invention has the advantages that the gap of the high-power LED integrated chip junction temperature test is filled, the testing equipment and the high-power LED lamp production line run simultaneously, the junction temperature unqualified product is detected at a high speed without missing.

Description

technical field [0001] The invention belongs to the field of LED technology, and in particular relates to a high-speed automatic detection device for the junction temperature of an LED integrated chip. Background technique [0002] As a new type of green light source, LED has the characteristics of energy saving, environmental protection, long life and small size. It can be widely used in various fields such as indication, decoration, backlight, ordinary lighting and urban lighting, and has become the trend of future development. [0003] The LED junction temperature refers to the temperature of the P-N junction region, which is also commonly understood as the temperature of the LED chip, which is an important parameter that directly affects the working life of the LED. As we all know, if the junction temperature of LED is too high, serious light decay will occur. Every time the junction temperature of the LED rises by 10℃, its life will be doubled. Therefore, the junction t...
