Description

Technical Field

[0001] The invention relates to the technical field of PCBA boards, and in particular to an intelligent face recognition PCBA board connection whole machine detection device. Background Art

[0002] The smart face recognition PCBA board is an embedded hardware circuit used to implement face recognition functions. It usually consists of a main control chip and a series of auxiliary circuits, such as sensor interface, power management, communication interface, etc. These auxiliary circuits are usually custom developed to meet the specific needs of users. The principle of the smart face recognition PCBA board is to capture facial images through special sensors installed in the camera and process these images using corresponding algorithms to identify the features of the face. These features can be used to confirm whether they match known identity information or are just random faces. This technology is widely used in security systems, access control, identity authentication and other fields.

[0003] When testing the PCBA board, a device is used to fix the PCBA board on a test platform, and then the test platform is connected to the whole machine for precise testing. In the existing testing device, in order to prevent the PCBA board from moving or shaking in the whole machine during the testing process, a clamping mechanism is usually provided. However, the existing clamping mechanism is generally for relative clamping, resulting in only clamping on both sides of the PCBA board, and the stability strength is not high enough, and it is not convenient to clamp and fix PCBA boards of different specifications, affecting the electrical connection and inspection accuracy. In addition, the current inspection device is generally placed directly on the desktop for use, and there is no positioning structure during use, which makes it easy to cause bumps and falls, which not only affects the detection work, but also causes a considerable loss.
