Visual inspection automation equipment screening machine special glass tray
Product Description
Optical image screening glass plate:
As a working platform for the detection of magnetic material workpieces, precision screws, nuts, small metal parts, and other precision electronic components, optical screening glass discs have extremely high requirements on the surface accuracy and optical transmittance of the glass. Traditional domestic glass discs have poor surface flatness and more air bubbles and impurities, which interfere with optical imaging; long-term contact with the glass for the components to be tested can easily cause scratches on the glass surface.
Product advantages and characteristics:
a) Extremely high heat resistance and excellent acid and alkali resistance will not be deformed in extremely harsh environments; b) The glass contains very little impurities, thereby reducing the interference of optical noise; c) Excellent optical transparency , To better ensure the authenticity of optical imaging;
e) Excellent scratch resistance and abrasion resistance, greatly enhancing the service life of the glass plate;
f) Very low glass density, 20% weight reduction compared to traditional glass under the same volume, thereby reducing the risk of glass warping caused by the weight of the glass
Technical parameters of optical image screening glass plate:
a) Material: high borosilicate ultra-white glass c) Standard thickness: 3.8, 5.0, 5.5, 6.5, 7.5, 9.0mm (different thicknesses can be customized according to customer needs) d) ** size: outer diameter Φ550 outer diameter Φ130; Outer diameter Φ520, inner diameter Φ300; inner diameter Φ500, outer diameter Φ300 (with positioning tapered hole, can be customized according to customer requirements)
