Description

Keyboard surface contour detection device

technical field

The utility model relates to a keyboard surface profile detection device.

Background technique

The traditional keyboard contour detection adopts the method of fixing the industrial mold and manual visual inspection. The operator first puts the keyboard into the corresponding mold, exposes the keyboard keycap, and manually observes the protruding height of the keycap. This detection method is subject to human subjective Influenced by factors, the detection accuracy is low, and human observation is the height difference between the mold surface and the keycap, and the height difference between the non-keyboard base plane and the keycap is an indirect dimension, which is different from the actual size.

Utility model content

The purpose of the utility model is to provide a keyboard surface profile detection device, which can accurately detect the keyboard surface profile.

In order to achieve the above object, the technical solution of the utility model is to design a keyboard surface profile detection device, comprising:

workbench,

Flat slide rails with work surface,

A flat slide that slides with the rails,

A driving device for driving the sliding plate to translate along the slide rail,

Clamps on the slide for fixing the flat keyboard,

A slide plate position detection device installed on one side of the slide rail to detect the horizontal position of the slide plate,

A height detection component arranged directly above the slide rail for detecting the height information of the keyboard keycap and the keyboard base;

The height detection component consists of an industrial camera and a linear laser generator that cooperate with each other.

Preferably, the industrial camera and the linear laser generator are installed at an off-angle.

Preferably, the deflection angle is 30 degrees.

Preferably, the keyboard surface profile detection device further includes an industrial computer for controlling the operation of the driving device, the industrial camera and the linear laser generator.

Preferably, the industrial computer is built with a motion control module, an image acquisition module and an image processing module.

The advantages and beneficial effects of the utility model are: to provide a keyboard surface contour detection device, which can accurately detect the keyboard surface contour.

Through the combination of industrial camera and linear laser generator, the height information of the keyboard keycap and keyboard base can be detected, and the position detection device can be used to accurately locate the measurement position of the keyboard. The combination of the three realizes the detection of the three-dimensional contour of the keyboard surface , improving the efficiency and precision of keyboard detection.
