Test device and method for positively emitting led light strips

Abstract

The invention relates to a testing device and method for a positively emitting LED light bar, including a light bar carrier, a plurality of light bars fixed on the light bar carrier, a light bar power supply module, a light bar test board, a digital camera and a calculation control unit, and a light bar The strip power supply module supplies power to the LED light through the PIN pin. The PIN pin is fixed on the light strip test board, one end of which is tied to the light strip pin, and the other end is connected to the light strip power module. There is a light-transmitting device on the light strip test board. The light strip test board is positioned above the light strip carrier through the positioning device. The digital camera is fixed above the light strip test board. The LED light irradiates on the digital camera through the light strip test board. The camera is connected to the computing control unit, and the computing control unit processes the images taken by the digital camera to determine whether the LED lamp is a defective product or a genuine product and determine its specific position. This method can measure 10 to 60 items at the same time, and the speed is 10 to 60 times higher than manual work. The test specifications are based on numerical values ​​to ensure stability and accuracy, save costs, improve efficiency, and ensure quality.

Description

technical field [0001] This patent relates to a testing device and method for positively emitting LED light bars. Background technique [0002] The LED light bar test is generally manually plugged in and then visually observed the LED lights on and off, bright and dark, color shift and other issues, the detection speed is slow and the resolution is poor, and the bright LED lights are harmful to human eyes. Large, for the automatic testing method, the industry generally adopts the mechanical one-by-one testing method. Although the accuracy is high, the testing speed is slower than manual testing, and cannot be used for production testing on the industrial site. Contents of the invention [0003] In order to solve the above problems, this patent provides a test device and method for positively emitting LED light strips, which has no uncertain influence of human factors, ensures stability and accuracy, and can fully meet the online testing requirements of LED light strips. In...
