Problems solved by technology

At present, manual inspection is still used in most production lines. Inspectors rely on their experience to inspect PCB single boards one by one through visual inspection. The detection accuracy of this method is affected by the inspector's experience and fatigue, which consumes manpower and is slow. , unable to meet the needs of rapid detection, resulting in relatively low work efficiency
Considering the three aspects of detection speed, detection efficiency and cost control, it does not meet the requirements of large-scale integrated production of enterprises.

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0026] Such as figure 1 As shown, the PCB single board fault detection device of the present invention comprises:

[0027] The vibration module, whose input is the control information output by the control module, causes the PCB single board to start to vibrate, which is used to induce potential faults such as weak soldering of the PCB single board, so as to be further screened out in subsequent steps.

[0028] The infrared collection module, whose input is the control information output by the c...

Abstract

The invention provides a PCB single board fault detection device. The device comprises a vibration module of which input is control information output by a control module, an infrared acquisition module which is used to collect the temperature distribution on the surface of the PCB single board and generate an infrared thermogram, an intelligent diagnosis module which realizes intelligent detection and self-diagnosis through a convolutional neural network deep learning model, a display module which is used to display the current state of the PCB single board, and a control module which is usedto control operation of a detection process. The PCB single board fault detection device improves PCB single board fault detection efficiency and detection accuracy, reduces the labor intensity of the operator, is easy to operate and has high detection efficiency and high detection precision.

Description

technical field [0001] The invention relates to a detection device, in particular to a PCB single board fault detection device. Background technique [0002] PCB (Printed Circuit Board, printed circuit board) is a provider of electrical connections for electronic components. PCB single board is a kind of the most basic printed circuit board, and its parts concentrate on wherein one side, and wire then concentrates on the other side. During the production process, PCB single boards may have bad faults of patches, discrete components or solder joints, which need to be detected for faults. At present, manual inspection is still used in most production lines. Inspectors rely on their experience to inspect PCB single boards one by one through visual inspection. The detection accuracy of this method is affected by the inspector's experience and fatigue, which consumes manpower and is slow. , unable to meet the needs of rapid detection, resulting in relatively low work efficiency...
