By installing the second camera 6.7 on a linear slide composed of a screw rod 6.1, a bracket 6.2, a motor 6.3 and a support plate 6.4, the lifting and lowering of the second camera 6.7 is realized. The shooting height can be flexibly adjusted by lifting the second camera 6.7 to meet the inspection requirements of different products, and at the same time, the light source 6.11 is driven to rise and fall, and the irradiation height can be freely adjusted.

[0025] Light sources 6.11 are arranged on both sides of the second camera 6.7.
