Abstract

The invention discloses a sapphire crystal ingot profile measuring device. The device comprises a base, a rotating table, and a portal frame. The portal frame comprises two portals that are opposed to each other. The rotating table is disposed between the two portals. Each portal comprises two stand bars, a transmitter laser scan sensor and a receiver laser scan sensor. Each stand bar is vertically disposed on the base. Each transmitter laser scan sensor is slidingly disposed on one stand bar, and the receiver laser scan sensor is slidingly disposed on the other stand bar. A scan laser beam is formed between the transmitter laser scan sensor and the receiver laser scan sensor. The scan laser beam is used for scanning sizes of periphery and profile of a sapphire crystal ingot disposed on the rotating table from the top down and from different rotating angles, in order to reestablish 3D profile image of the sapphire crystal ingot with the help of interpolation algorithm. The device enables profile measurement of a sapphire crystal ingot in an efficient, reliable and accurate manner.

Description

technical field [0001] The invention relates to the technical field of profile measurement, in particular to a device for measuring the profile of a sapphire crystal ingot. Background technique [0002] At present, most of the sapphires used in the industry are materials produced by the Kyropoulos method. The shape of the sapphire crystal ingots grown in this way is irregular, so it is difficult to maximize the utilization when squaring. Due to the high cost of sapphire production, there is an urgent need for a method to improve the utilization rate of sapphire crystal ingots during square cutting, and to achieve the maximum utilization rate, measuring the profile of sapphire crystal ingots is the most basic condition. However, due to the irregular shape of the sapphire boule and the transparent material, there are great difficulties in profile determination. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sap...
