Problems solved by technology

[0003] At present, in the factory assembly line, the detection of notebook keyboards is mainly to compare the operator with the standard template with naked eyes and then judge the eligibility. The detection speed is slow, the subjectivity is high, the cost is high, and misjudgment is easy to occur.
Static optical inspection is introduced in a few assembly lines, and there are few types of inspection items and cumbersome manual operations are still required, resulting in low efficiency and high labor costs

Abstract

The invention provides a dynamic optical detection device and detection method for laptop keyboards. The dynamic optical detection device comprises a camera, a touch screen displayer, an industrial personal computer, a stepping motor, a sorter, an assembly line testing table for storing the keyboards to be detected, and an illuminating device. The stepping motor drives the assembly line testing table to move. The camera and the illuminating device are arranged above the assembly line testing table. The camera is used for photographing the keyboards to be detected and generating to-be-detected photos. The touch screen displayer, the camera and the illuminating device are electrically connected with the industrial personal computer. The sorter is arranged at the discharging end of the assembly line testing table and used for discharging of the keyboards after detection is completed.

Description

technical field [0001] The invention relates to a detection system based on machine vision, in particular to a notebook keyboard dynamic optical detection device and detection method. Background technique [0002] Computer notebooks have been widely used in daily life such as office, study, and entertainment. Although the development of touch screens has matured, the speed of text input is limited by the writing speed. Therefore, the notebook keyboard is still playing an important role, and the needs are diversified and personalized. [0003] At present, in the factory assembly line, the detection of notebook keyboards is mainly to compare the operator with the standard template with naked eyes and then judge the eligibility. The detection speed is slow, the subjectivity is high, the cost is high, and misjudgment is easy to occur. Static optical inspection is introduced in a few assembly lines, and there are few types of inspection items and cumbersome manual operations are...
