Automatic test method for color backlight module of notebook computer keyboard

Abstract

An automatic test method for the color backlight module of a notebook computer keyboard comprises the steps that a pneumatic sucker on a mechanical arm sucks up a test sample and places the test sample on the upper surface of a test equipment body, and an LED lamp of the test sample falls into a color sensor window; a pressing platform descends, the pressing probe presses the back surface of the LED lamp to make the test sample generate micro-deformation, and the test probe on the pressing platform presses a golden finger of the test sample; if the 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 an automatic 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,...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an automatic testing method for the color backlight module of the notebook computer keyboard, to solve the problem that the detection of the color backlight module of the notebook computer is completed through manual visual inspection, and 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 colors will decrease, so the reliability of the inspection results cannot be guaranteed.
