Abstract

The invention discloses an intelligent detection method and device for an LED lamp bead keyboard backlight module based on polar coordinates. The intelligent detection method comprises the steps thatthe to-be-detected keyboard backlight module placed on a push disc enters a box body of the detection device; after a control unit drives the LED lamp beads on the to-be-tested keyboard backlight module to emit light of a preset color, a camera module carries out first period shooting on the to-be-tested keyboard backlight module; the control unit obtains coordinates of all LED lamp beads of the keyboard backlight module to be tested by judging shot first period picture data, sequentially scans and counts results according to light rays with preset colors emitted by the LED lamp beads on the keyboard backlight module to be tested, and presses down a keyboard backlight module pressing plate; and the control unit compares the shot second period picture data with shot first period picture data, and if the shot second period picture data and the shot first period picture data are consistent, the to-be-tested keyboard backlight module is qualified. According to the invention, the problem ofhow to detect false welding under the conditions of vibration and external pressing in the detection of the keyboard backlight module at present is solved.

Description

technical field [0001] The invention relates to the field of machine vision recognition, in particular to an intelligent detection method and device for a LED lamp bead keyboard backlight module based on polar coordinates. Background technique [0002] The computer keyboard backlight module is one of the key components of the computer. With the development of the computer keyboard backlight module, the number of LED lights integrated on the computer keyboard backlight module is increasing. Facing dozens or even hundreds of color For LED light testing, it is difficult to guarantee the efficiency and reliability of testing the computer keyboard backlight module by simply relying on manual visual inspection. In order to solve the problem of false soldering of LED lamp beads, in the case of false soldering of simulated LED lamp beads, if there are adverse reactions such as vibration and pressing, it is difficult to obtain the required results through manual visual inspection. ...
