Description

Technical Field

[0001] This utility model relates to the field of millimeter-wave imaging detection technology, specifically to a millimeter-wave imaging detection system based on a modular bracket for rapid installation. Background Technology

[0002] With the development of industrial automation inspection needs, the demand for online inspection of items has shown a significant increase. Examples include online dielectric parameter testing of printed circuit boards, online inventory counting of packaged products, and detection of missing items. Currently, online inspection of items using millimeter-wave technology is a rapidly developing technological field in recent years. However, installing existing millimeter-wave imaging systems in industrial inspection production lines requires modifications to the existing production lines. The installation of existing millimeter-wave imaging systems has the following shortcomings:

[0003] 1) The installation of traditional millimeter-wave imaging systems requires the customization of many complex mounting brackets or structures to fix the control host, transmitting electronic instruments, receiving electronic instruments, millimeter-wave transmitter, and millimeter-wave receiver of the millimeter-wave imaging system. These mounting structures and the millimeter-wave imaging system all require floor space, resulting in a large floor space required for millimeter-wave imaging systems.

[0004] 2) The cost of modifying existing production lines would be relatively high, with issues such as complex installation, long construction period, and high deployment costs;

[0005] 3) During the production line transformation process, the millimeter-wave imaging system uses a complicated wiring connection method, which also needs to penetrate the production line equipment, requiring production to be stopped. For some production lines that have been debugged, if production is stopped, subsequent debugging will be required, which will affect the processing efficiency of the production line.
