[0002] In the manufacturing process of electronic component modules such as liquid crystal panels and integrated circuits, it is often necessary to perform conduction detection and action characteristic inspection. This usually requires the use of elastic metal sheets to connect the main substrate of the electronic component module with the corresponding FPC contact electrodes, and then complete the corresponding inspection work. After the elastic metal sheet is produced, it is necessary to observe its appearance to determine whether the elastic metal sheet is qualified.

[0003] In the prior art, when calibrating the shape of a metal sheet, a camera is used to take a picture of the shape of the metal sheet, which is then transferred to a computer for calibration. However, when the metal sheet is placed on a desktop, the metal sheet is prone to shaking due to external forces, resulting in inaccurate calibration of the shape of the metal sheet.
