Quality control analysis checks correct and complete assembly of parts
The pmd Profiler targets error proofing applications. It monitors the assembly, alignment and selection of components, subassemblies and final products. It also provides precise object inspection to check, for example, threaded screw depth or fastener locking.
By projecting a straight laser line, the pmd Profiler determines the height profile of objects it inspects. It compares the height profile with the reference taught profile and helps you identify non-conforming parts in real time and reject them earlier in the manufacturing process.
The pmd Profiler reaches a whole new dimension in error control. Camera systems can be sensitive to external light and 1D distance sensors require precise positioning making alignment challenging. The pmd Profiler is unaffected by external light and it reliably inspects objects even at varying distances.
Transmit additional information such as reject rate or match value to your higher level plant network for trending and process optimazation.
