Since the C-pillar guard product will have a certain amount of deformation after demolding, whether it meets the assembly requirements, it is necessary to inspect the produced C-pillar guard.

[0003] In traditional technology, plastic parts are mostly inspected by manual measurement to check the part surface and periphery. Since there are many locations on plastic parts that need to be measured, operators need to hold a micrometer and walk around the plastic parts to measure. There will be certain errors during inspection, and usually multiple sets of data need to be measured, which increases the intensity of manual labor and low inspection efficiency.

[0004] In the plastic parts inspection industry, automatic machines are commonly used for assembly and inspection. Although their production efficiency is high, automatic equipment is expensive and is not very suitable for the inspection and processing of small batches of multi-specification plastic parts.
