Position determination of ultra fine wires
The fine wires made of copper in smartphone speakers dispose of a high reflection and only a small diameter.
A high-resolution QuellTech 2D/3D Q4-5 Laser, featuring a particularly adapted laser wavelength and an ultrafine laser line in the corresponding installation, is combined with a linear axis equipped with a convenient encoder output. Due to its special chip analysis, the Quelltech sensor delivers a stable and highly reproducible signal on the fine wires. These signals are used to finally determine the position of the wire in space.
From now on, the client at reasonable cost is able to integrate a corresponding 100% inspection in his production process. Contact between speaker wires and components in the surroundings is reliably prevented, so short circuit and cable break at the end customer, affecting the safety and giving rise to considerable image damage, is avoided. Measuring results are documented with the QS-View Software.
