The application relates to a detection device and system for a cavity device. Among them, the detection equipment of the cavity device includes a vibration device, a vibration sensor and a main control circuit; the main control circuit includes a signal generation circuit and a chip; the chip is respectively connected to the signal generation circuit and the vibration sensor; the signal generation circuit is connected to the vibration device; The circuit transmits the vibration driving signal to the vibration equipment, so that the components to be tested on the vibration equipment are in the corresponding vibration state; the chip receives the electrical signal transmitted by the vibration sensor attached to the outer surface of the component to be tested, and outputs based on the electrical signal The location of redundant objects inside the component under test. The detection equipment for the cavity device provided by this application improves the accuracy of the detection results. In the traditional technology, it is necessary to observe the electrical signal transmitted by the sensor through an oscilloscope, and obtain the detection result according to the parameters such as the waveform of the electrical signal. However, in the present application, the position of redundant objects can be directly output, which greatly improves the detection efficiency.
Description
technical field [0001] The present application relates to the technical field of cavity device detection, in particular to a detection device and system for cavity devices. Background technique [0002] Sealed cavity components are the basic components widely used in national defense and aerospace electronic systems. The reasons that affect the reliability of devices include design defects, process structure defects, and internal redundant particles. Defects in design and process structure are mostly found in the process of daily use, and whether there are redundant particles can be judged according to the test results obtained from the test. Therefore, it is particularly important to carry out redundant inspection of sealed cavity components before use or before the product leaves the factory. [0003] During the implementation process, the inventors found at least the following problems in the traditional technology: the traditional detection equipment has the problem of ...
