Inspection tool for assisting printed circuit board with structural member in automatic optical inspection

Abstract

The invention discloses an inspection tool for assisting a printed circuit board with a structural member in automatic optical inspection. The inspection tool comprises a tray (1), a fixed side plate(2), a movable base (8) and a base guide rail (5), wherein the fixed side plate (2) is fixed to one side of the tray (1) through a fixed side plate bolt (10), a step is arranged on the side, facing the tray (1), of the top end of the fixed side plate (2), and the height from the bottom surface of the step to the tray (1) is the height of the printed circuit board with a structural member; two baseguide rails (5) are vertical to the fixed side plate (2); the base guide rails (5) are fixed to the front face of the tray (1) through base guide rail bolts (6); a movable base (8) is limited betweenthe two base guide rails; and after one end of the printed circuit board with the structural member is placed on the fixed side plate (2), the movable base (8) is moved to fix the other end of the printed circuit board with the structural member. Thus, automatic optical inspection of the printed circuit board after installation of the structural member can be realized.

Description

technical field [0001] The invention belongs to the technical field of inspection of printed circuit boards, and in particular relates to an inspection tool for automatic optical inspection of printed circuit boards with structural parts. Background technique [0002] With the development of science and technology, printed circuit boards have been widely used in aviation, aerospace, automobile, medical and other fields. Due to the small size, large quantity, and complex types of components, defects such as wrong parts, missing parts, and displacement of components will occur during the manufacturing process of printed circuit boards, which will affect the functional performance of printed circuit boards. At present, the inspection of printed circuit boards includes methods such as manual visual inspection and automatic optical inspection. Automatic optical inspection is to use optical means to obtain the surface state of the finished product, compare it with the qualified p...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an inspection tool for automatic optical inspection of printed circuit boards with structural parts, which can realize automatic optical inspection of printed circuit boards "after the structural parts are installed", and overcome the existing automatic optical inspection. Due to "focus limitation", the detector cannot implement automatic optical inspection of printed circuit boards with structural parts, which optimizes the inspection process
