Description

Line Scan Optical Inspection Machine

technical field

The utility model relates to the field of line scanning detection, in particular to a line scanning optical detection machine.

Background technique

The traditional keyboard detection equipment is equipped with a discharge port. The keyboard is manually placed on the discharge port, and then the keyboard is moved to the detection component for detection. This method has a low degree of automation and cannot meet the needs of the current flexible production line. After setting the discharge port, the external light will affect the internal detection, resulting in inaccurate detection results.

Utility model content

The purpose of this utility model is to provide a line-sweep optical detection machine for the deficiencies of the existing technology, which solves the problem that in the existing AOI detection, it needs manual loading and unloading one by one, the detection speed is slow, and the detection accuracy is low, which cannot meet the requirements of flexibility. The problem of automatic production line needs.

The technical scheme that the utility model adopts for realizing the above object is:

A line-scan optical detection machine, which includes a casing, a frame, and an object-to-be-tested delivery table running through the left and right sides of the frame; Above the measuring object conveying workbench, the line-scanning optical detection mechanism includes two line-scanning cameras arranged side by side, and a detection light source is provided between the line-scanning camera and the measuring object conveying workbench; a display is fixed on one side of the frame , the inside of the shell is also provided with a control host, and the control host is located under the transfer table of the object to be tested.

The detection light source is an adjustable detection light source, which can move laterally on the frame through the movable telescopic frame, and can be vertically flipped and moved up and down on the movable frame to meet different detection needs.

The line-scanning camera is fixed to a beam through the line-scanning camera, and is arranged laterally inside the casing.

The detection light source is fixed on the frame through connecting rods arranged on both sides of the detection light source, and is located between the line scan camera and the workbench for conveying the object under test.

The display is fixed on the frame through a horizontal fixing frame.

A keyboard and mouse console is also arranged in front of the display, and the keyboard and mouse console is fixed on the display through a bending connector.

A conveying belt is arranged on the workbench for conveying the object to be tested, and the conveying belt is driven by a servo motor to work.

The beneficial effects of the utility model are: the line-sweep optical detection machine of the utility model realizes the perfect combination with the automatic production line by setting the object-to-be-tested transmission table, and can quickly detect the printing on the appearance of the keyboard, including broken wires. , Missing printing, excessive ink, wrong button installation, etc. are detected. The utility model adopts a closed shadowless lighting environment, so that the measurement results are more stable and consistent, the detection speed is greatly improved, and the production efficiency is improved.
