Description

Technical Field

[0001] The utility model relates to the technical field of optical films, in particular to an optical film defect detection device. Background Art

[0002] Optical thin film devices include reflective films, anti-reflective films, polarizing films, interference filters, and spectroscopes, etc. They have been widely used in national economy and national defense construction, and have received increasing attention from scientific and technological workers. For example, the use of anti-reflective films can reduce the light flux loss of complex optical lenses by ten times; the use of high reflectance mirrors can double the output power of lasers; the use of optical films can improve the efficiency and stability of silicon photovoltaic cells. After the optical films are processed, defect detection is required to ensure the quality of the products.

[0003] Existing technologies, such as: CN218231208U, a plastic film defect detection device, is driven by a motor to rotate the lead screw, and the lead screw drives the movable plate to move through the action of the lead screw nut. The movable plate adjusts the distance between the limit plates during the movement, which can limit the detection of films of different widths, and at the same time, the workbench can be leveled by rotating the threaded rod.

[0004] However, the device still has certain shortcomings when in use. Since the device only guides and adjusts the film through the first guide wheel, the second guide wheel and the third guide wheel, it cannot reel up the film after inspection and can only perform inspection, which reduces its practicality. Since the position of the defect detector is fixed and cannot be adjusted, when the angle of the film is offset, the value detected by the defect detector will deviate, reducing work efficiency.
