3C product design includes smart phones, smart
watches, tablets, wearable smart products, dashboards, and other 3D products
emerged one after another. 3D curved glass is characterized by lightness,
transparency and cleanliness, fingerprint resistance, and dazzle resistance,
hardness, scratching resistance, good weather resistance, etc., which can be
made into many shapes for various 3D products. Characterized by novel and
special design and good texture, it can add the excellent touch feeling and
wireless charging function brought by the touch function of the arc edge, solve
the problem of insufficient space for antenna layout and enhance the function
of receiving, so that products will be more beautiful and excellent.

As the increasingly popular 3D curved products, all major manufacturers
continue to launch a large number and a wide range of 3C products of different
models. Due to its features of complex process and high rejection rate, and in
terms of test and OQC of the production process of geometric dimensions, full
inspection often replaces the previous random inspection to prevent the loss of
rejected goods. The traditional image measurement system and the coordinate
measuring machine cannot handle a large number of inspections, and their poor
efficiency becomes the bottleneck of quality control. On the other hand, the
detection accuracy of 3D curved data also gradually tests a variety of
traditional measuring equipment. The rate of accidental injury caused by the coordinate
measuring machine remains high. The high price forces major manufacturers to
seek for more suitable measuring equipment.
The detection efficiency and precision of 2D is the first problem faced
by 3D curved glass. TZTEK VMQ432 uses the large field of vision and double-rate
system, so that the diameter of view reaches up to 100mm, and the measuring
efficiency is more than 10 times that of traditional optical instruments, so
that glass can be completed in only a few seconds. On the 400*300 platform,
glass placed in array has greatly saved the time for loading and unloading
materials. Since the accuracy of VMQ432 reaches up to 2um±L/200, it's highly
favored in terms of glass detection.
Combined with the independently developed high coverage flash-test
measuring system, TZTEK has redesigned the 3D curved measuring system. It has
added the spectral confocal sensor and achieved zero loss without deformation
through data of the non-contact measuring surface. The one-button operation
design and the design of multiple operating modes of the whole machine and the
original five-axis linkage mechanical structure perfectly solve the measuring
problems of various curvatures and materials.
