Device for automatically measuring side length of monocrystal after grinding

A device for automatically measuring a side length of a monocrystal after grinding, comprising:

• a detection table for placing the monocrystal to be detected;
• and
• measuring devices symmetrically arranged on opposite sides of the detection table respectively,
• wherein each of the measuring devices comprises:
• a first driver with an end connected to a side of the detection table, a column being provided above another end of the first driver, wherein the first driver is capable of driving the column to move horizontally;
• a mechanical arm disposed on a side of the column close to the detection table;
• a probe assembly disposed at an end of the mechanical arm away from the column;
• and
• a first sensor disposed on a mounting bracket on the mechanical arm, the mounting bracket being parallel to the detection table and extending towards the first driver, wherein the first sensor is disposed at an end of the mounting bracket away from the mechanical arm and facing a sensing surface of the detection table and is configured to measure a distance change relative to the sensing surface of the detection table.
