Description

Technical Field

[0001] The utility model relates to the technical field related to flatness measurement, and in particular to an off-line high-precision automatic imaging plate size flatness measurement device. Background Art

[0002] The flatness of a sheet refers to the flatness of the sheet surface when it is laid flat. It is also an important indicator for measuring the flatness of the sheet surface. In industrial production and construction, the flatness of a sheet is crucial to ensuring product quality and improving work efficiency. In the manufacturing industry, sheets that require high flatness are usually used in the manufacture of precision equipment, such as semiconductor manufacturing, optical instruments, etc. The higher the flatness, the better the precision requirements of the equipment can be met, thereby improving the quality and performance of the product. In the construction field, the flatness of a sheet directly affects the overall appearance and structural stability of a building. For example, sheets used for floors, ceilings or walls may be damaged if they are not flat enough. This leads to installation difficulties, affects the appearance, and may cause deformation or cracking of the building. In order to ensure the flatness of the plate, advanced flatness detection instruments and technologies, as well as precise production processes, are usually used in the production process, which helps to improve the quality of the plate and meet the strict requirements of flatness in different fields. During use, the existing plate size flatness measurement equipment often uses a continuously moving transmission mechanism when transmitting the plate. Since the continuously moving conveyor belt makes it difficult to stop the plate, vibration and deformation may be introduced during the transmission process, affecting the accuracy of the measurement. Therefore, there is a special need for an offline high-precision automatic imaging plate size flatness measurement device.

When conveying the plates, they often use a continuous motion conveying mechanism. The continuous motion mechanism cannot ensure that the measuring mechanism will not move when the plates move, resulting in instability in the flatness measurement, which has a certain impact on the measurement.
