Embodiment 1

[0021] figure 1 It shows the implementation process of the method for acquiring an image to be detected provided in Embodiment 1 of the present invention, and the details are as follows:

[0022] In step 101, the servo motor drives the printed circuit board to be detected to slide from a preset starting position to a preset end position;

[0023] In the embodiment of the present application, the above-mentioned servo motor can be controlled by a programmable logic controller (ProgrammableLogic Controller, PLC) or an embedded microcontroller. The printed circuit board to be detected can be bound on a sliding block, which is driven by a servo motor. When the servo motor drives the above sliding block, since the printed circuit board is bound to the sliding block, the printed circuit board It will also change position as the slider slides. Before the servo motor drives the above-mentioned printed circuit board, the inspector can preset the starting position and the end position...

Embodiment 3

[0052] image 3 A specific structural block diagram of the image acquisition system to be inspected provided by Embodiment 3 of the present invention is shown. For convenience of description, only parts related to the embodiment of the present invention are shown. The image acquisition system 3 to be detected includes: a servo motor 31, a printed circuit board 32 to be detected, a camera 33 and a computer terminal 34;

[0053] Wherein, the above-mentioned servo motor 31 is used to drive the above-mentioned printed circuit board 32 to slide from a preset starting position to a preset end position;

[0054] The above-mentioned camera 33 is used to obtain two or more target images during the process of the above-mentioned printed circuit board 32 sliding from the above-mentioned starting position to the above-mentioned end position, and upload the above-mentioned two or more target images to the computer terminal 34, wherein, The above-mentioned target image is a partial image o...

Abstract

The invention discloses a to-be-detected image acquisition method and a to-be-detected image acquisition system, and the to-be-detected image acquisition method comprises the steps: enabling a servo motor to drive a printed circuit board to slide from a preset start position to a preset end position; in the process that the printed circuit board slides from the initial position to the final position, obtaining more than two target images by a camera, wherein the target images are local images of the printed circuit board; uploading the more than two target images by the camera to a computer terminal; and spicing the more than two target images, by the computer terminal, into an image to be detected. According to the scheme, the complete to-be-detected image of the printed circuit board canbe quickly obtained under the condition of not contacting the printed circuit board, and the detection efficiency and accuracy are improved.

Description

technical field [0001] The application belongs to the technical field of electronic detection, and in particular relates to a method for acquiring an image to be inspected and an image acquisition system to be inspected. Background technique [0002] At present, in the printed circuit board (Printed Circuit Board, PCB) manufacturing industry, the accuracy of the line width and line spacing of the printed circuit board has reached 0.10-0.12mm; and the number of layers of the printed circuit board has reached 46 layers Even more, combined with the rapid development of current microelectronics technology, it can be seen that the processing and manufacturing technology of printed circuit boards has reached a relatively high level; at the same time, components on printed circuit boards are also developing towards miniaturization and precision. At present, the detection methods of printed circuit board defects are mainly traditional human eye detection and online detection with pr...
