[0002] During the production and processing of ceramics, the height of the ceramics needs to be measured frequently to determine whether the ceramics are qualified.

[0003] The existing method of inspecting ceramic products is to convey the ceramic products to the inspection station via a conveyor belt. The inspector takes the ceramic products from the conveyor belt and uses a micrometer to find the inspection points for multiple times to detect the product height. The qualified products are placed back on the conveyor belt after inspection. This operation requires multiple contacts with the ceramic products, which sometimes damage or dirty the products, affecting the appearance of the ceramic products. Secondly, if the product has a large change in height, the altimeter needs to be readjusted and replaced, which has poor compatibility and can only inspect one point at a time, resulting in low inspection efficiency.
