Method for testing color backlight module of notebook computer keyboard

Abstract

A method for testing the color backlight module of a notebook computer keyboard comprises the following steps that a mobile platform moves a test sample to fall on the upper surface of a test equipment body, and an LED lamp falls in a color sensor window; a pressing platform continues to descend to compress a spring and descend a probe fixing plate, after the pressing probe presses the back surface of the LED lamp downwards, the LED lamp part generates micro deformation, and meanwhile, a test probe presses a golden finger of the test sample downwards; if a test circuit board judges that a feedback signal of a loop formed by the test probe and the golden finger of the test sample is received, current signal data is acquired and sent to a data processing unit after the condition that poor contact does not exist in the connection of the test probe and the golden finger of the test sample is determined; and the color sensor collects brightness signal data of the LED lamp and sends the brightness signal data to the data processing unit. According to the invention, the problems that the false welding condition of the LED lamp cannot be eliminated and the brightness difference of different LED lamps cannot be accurately mastered through manual visual inspection in the current notebook computer color backlight module detection are solved.

Description

technical field [0001] The invention relates to the field of testing color backlight modules, in particular to a testing method for notebook computer keyboard color backlight modules. Background technique [0002] The notebook computer keyboard backlight module is installed under the notebook computer keyboard, and enhances the possibility of using the keyboard in scenes with low ambient light by emitting light. With the decrease of the production cost of the notebook computer keyboard backlight module and the change of people's aesthetics of the keyboard backlight, the colorful notebook computer keyboard backlight has gradually become a trend. However, at present, the detection of color backlight modules of notebook computers is basically completed through manual visual inspection, and false welding of RGB-LED lamps cannot be ruled out, and the brightness difference of different LED lamps cannot be accurately grasped. As the working hours of inspectors increase, the degree...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a method for testing the color backlight module of a notebook computer keyboard to solve the problem that the current color backlight module detection of a notebook computer is completed through manual visual inspection, false welding of RGB-LED lights cannot be ruled out, and different LED lights cannot be accurately grasped. At the same time, with the increase of the working hours of the inspectors, the degree of eye fatigue will deepen, and the sensitivity to color will decrease, so the reliability of the detection results cannot be guaranteed.
