Laser sensor outshines the alternatives for product inspection

摘要

You might think that an inspection system capable of checking whether or not a metal compression limiter is correctly installed within the plastic housing of an automotive component was not going to tax the system designers unduly. In reality, however, that task was going to prove a bit of a teaser until a trusted supplier came up with a bright suggestionrnA major supplier of components to the automobile industry had approached bespoke production equipment specialist, Alphr Technology to design and manufacture two machines. The first would heat metal compression limiters to 380℃ within a few seconds by induction, and would then press them into the top of a plastic component. The second machine would inspect and leak test each component to ensure that the limiters protruded by the correct distance above its surface. A measurement accuracy of +/-0.3mm or better was needed.
