How to judge the visual inspection of 6mm diameter Dual-lens camera module? With the development of industry and the advancement of scientific research technology, 6mm diameter Dual-lens camera module is more and more widely used in industry, so how to judge 6mm diameter Dual-lens camera module? What about the visual inspection of the lens camera module?

1. Pull lines and scratches: Under the irradiation of the light beam, it is observed that there are relatively regular continuous long lines on the surface, which are judged as pull lines.

2. Unwanted objects: When the light beam is irradiated at any angle, objects other than structures that have different color and brightness from the surrounding basic inspection object are redundant objects.

3. Crack: When the light beam irradiates the surface of the object to be detected, black or bright lines are observed, and under a certain magnification, the lines have irregular edges, which are determined as cracks. When the crack is wide, the measurement influence line of the measurable probe will bend.

4. Welding leakage: When the light beam is irradiated at a certain angle, it is observed that it is connected to the molten metal, and there is no protrusion of the dividing line, which is a welding leakage.

5. Corrosion: Under the irradiation of the light beam, the lumpy and spot-shaped uneven surface is observed, and the slight unevenness is corrosion under a certain magnification.

6. Incomplete penetration: It is observed that there is a clear dividing line between the molten metal, the base metal and the weld layer.

7. Peeling: When the beam is irradiated in parallel, it is observed that there is a shadow behind the convex part; if the beam irradiation angle is changed, it is observed that there is a clear dividing line between the convex part of the surface and the surrounding detected object, and it is judged to be peeling.

8. Spots: When the beam is irradiated, it is observed that the smooth and non-concave-convex surface that is different in color from the surrounding object is spots.

9. Assembly defects: Structural phenomena that do not meet the technical conditions of the drawings are observed during inspection.
