Abstract

The invention discloses a device for automatically detecting the thickness of a sapphire wafer. The device comprises a support machine frame, an upper visual device, a detection device, a guide installation plate, a lifting conveying device, a lower visual device and a marble detection platform; the upper visual device and the lower visual device are used for finding the initial detection positionof the sapphire wafer and capable of reading and detecting the data index of the thickness of the sapphire wafer printed on a ceramic plate; the detection device is used for measuring the thickness of the sapphire wafer; the lifting conveying device can realize automatic horizontal transportation and vertical lifting transportation of the ceramic plate; the fact that the ceramic plate is automatically transported to a detection position is realized; the marble detection platform is used for placing the ceramic plate; and the detection stability and accuracy can be ensured. The device in the invention has the advantages of being high in detection efficiency, detection precision and automatic degree, simple in structure, convenient in assembly and maintenance and high in compatibility.

Description

technical field [0001] The invention relates to the vision measurement range of an automatic assembly line machine, in particular to an automatic detection device for detecting the thickness of a sapphire wafer. Background technique [0002] Sapphire (Sapphire, also known as white gem, molecular formula Al2O3) single crystal is an excellent multifunctional material. It has high temperature resistance, good thermal conductivity, high hardness, infrared transmission, and good chemical stability. Widely used in many fields of industry, national defense and scientific research, these fields have strict requirements on the thickness of the sapphire wafer used. [0003] The mainstream of current technical production is to manually use traditional methods to measure the thickness of sapphire wafers. Generally, digital display dial gauges are used as measurement tools, which is inefficient, has many single-point measurements, and has large errors. At the same time, it brings about ...
