Description

Technical Field

[0002] Circuit boards, also commonly known as printed circuit boards, are supports that connect electronic components and circuits together. They are used to implement layout design of complex circuits and electrical signal transmission in electrical and electronic equipment. When producing and processing circuit boards, it is necessary to detect whether abnormal vibration conditions occur during the operation of the circuit boards, so corresponding abnormal vibration detection devices are required.

[0003] Reference publication number CN215726801U is a bearing abnormal vibration detection device, which includes a box body and a rotating mechanism. The upper surface of the box body is fixedly connected to a support rod, the upper surface of the support rod is fixedly connected to a camera, the upper surface of the box body and the rear side of the support rod is fixedly connected to a display screen, the upper surface of the box body and the right side of the support rod is fixedly connected to a glass block, the upper surface of the box body and the right side of the glass block is fixedly connected to a baffle, and the rotating mechanism includes a bottom plate, a support rod, and a motor. This device realizes the detection of bearings using optical levers by designing laser lights, glass blocks, cameras and baffles, thereby achieving the purpose of increasing detection accuracy, and realizes the detection of bearing sound by designing a display screen and a microphone, thereby achieving the purpose of increasing the detection dimension by observing whether an abnormality occurs through the waveform diagram of the sound, and reducing the influence of motor vibration on detection by designing a rotating mechanism. Another example is a PCBA circuit board multi-angle vibration detection device with publication number CN216621447U. It includes a vibration detector body and a telescopic support. A display screen is arranged on the front side of the vibration detector body. A detection sensing head is fixedly connected to the bottom of the vibration detector body. A second telescopic spring is arranged between the top seat and the sleeve block through a top seat and a sleeve block, and a first telescopic spring is arranged between the telescopic support and the vibration detector body. Through the elastic force of the two sets of telescopic springs, twisting the rotating handle can drive the rotating capstan to rotate. Since the traction rope is wound around the outside of the rotating capstan, the traction rope can be unfolded through the rotation of the rotating capstan. A hinge device is arranged between the top seat and the sleeve block. The unfolding angle can be determined according to the size of the PCBA circuit board to be detected as needed. The first telescopic spring and the second telescopic spring mainly support the vibration detector body. No handheld detection is required, which reduces the workload. According to the above, although this type of detection device can be well applied, it is usually not convenient for sealed detection of workpiece vibration, which makes it difficult for the device to achieve the established expectations for the vibration detection effect of the workpiece, which often troubles people.
