In view of the above technical problems, it is urgent to develop a more mature general auxiliary device for arc-shaped electronic component welding detection. SUMMARY

[0006] Compared with the prior art, the present application has the beneficial effects that: the electronic components with different arc-shaped structures are rotated and scanned to ensure that the curvature and thickness information is fully obtained, and through dynamic fusion analysis of multiple sub-modules, the better positioning point can be flexibly selected according to the actual form of the component, different positioning point distributions can be adapted, and multiple specifications of arc-shaped components can be adapted without replacing the clamps, which greatly improves the positioning adaptability.
