Description

Technical Field

[0001] The present application relates to the technical field of lens finish detection, and in particular to a lens finish detection device and method. Background Art

[0002] Smoothness refers to the unevenness of the machined surface with small spacing and tiny peaks and valleys. The distance (wavelength) between two wave crests or two wave valleys is very small (less than 1mm), which belongs to the microscopic geometric shape error. The smaller the surface roughness, the smoother the surface. Usually, the morphological features with a wavelength less than 1mm are attributed to surface roughness, (the morphological features with a size of 1-10mm are defined as surface waviness, and the morphological features with a size greater than 10mm are defined as surface morphology. During the production and inspection of the lens, the lens needs to be inspected for smoothness, because the material defects (or cracks) of the lens and the surface sub-damage formed during the processing will affect the compressive strength of the lens, and the existing processing technology and inspection conditions cannot directly detect the more subtle surface defects of the lens sub-surface.

[0003] The traditional method of testing the finish of lenses is to use manual testing. The test personnel usually test the finish of the lens under incandescent light. When the requirements are high or it is difficult to observe, a handheld lighting is used to illuminate the lens and the naked eye is used to observe whether the lens has any appearance defects. This detection method is prone to missing areas and has low detection reliability. In addition, the lens needs to be constantly cleaned during the test to reduce the impact of dust on the test. In addition, some lenses are coated on the surface, and wiping will cause scratches on the coating. The test takes a long time and the operation is cumbersome. There is an urgent need for a lens finish detection device to improve the detection efficiency. Summary of the invention

[0004] The object of the present invention is to provide a lens finish detection device, comprising a dust cover part, an electric control sliding frame part, a detection probe arm part, a workpiece turntable part and a dust removal nozzle head. The detection probe arm part is installed on the electric control sliding frame part, and the workpiece turntable part is installed on the platform of the dust cover part. When the finish of the lens is detected, the lens is placed on the workpiece turntable part, and the lens is blown and cleaned through the dust removal nozzle head installed on the platform of the dust cover part to reduce the influence of dust on the detection. The electric control sliding frame part drives the detection probe arm part to move to the top of the lens, and the detection probe arm part performs image transmission detection on the lens placed on the workpiece turntable part to determine whether the lens has appearance defects in the transmitted image to achieve the purpose of detecting the finish. There is no need for the detection personnel to illuminate the lens with lighting fixtures and observe whether the lens has appearance defects with the naked eye, and the detection efficiency is high.

A method for testing using the lens finish testing device according to any one of claims 1 to 8, characterized in that: It is used to detect the side of the lens, including the following steps: Step 1: Move the detection probe arm (300) to the center of the lens through the electrically controlled sliding frame (200); Step 2: The second joint motor (325) drives the telescopic arm (331) to rotate, and adjusts the angle between the telescopic arm (331) and the horizontal rotation arm (320) so that the camera probe (343) can be located on the side of the lens; Step 3: The second joint motor (325) drives the camera probe (343) to rotate so that the camera probe (343) is horizontal to the lens; Step 4: The first joint motor (324) drives the crossbar (321) to rotate in a circle, and the rotating probe (340) is used to capture images around the lens to obtain image information of the outside of the lens, and then observe whether the lens has any appearance defects.

10. A method for testing using the lens finish testing device according to any one of claims 1 to 8, characterized in that: Used to detect the lens surface, including the following steps: Step 1: The electrically controlled sliding frame (200) moves the detection probe arm (300) to the rear of the lens, and the lifting seat (310) retracts so that the rotating probe (340) can be located above the lens; Step 2: the first slider frame (210) and the second slider frame (220) drive the third slider frame (230) to move from the back to the front in the detection space; Step 3: when passing through the lens, the third slider frame (230) drives the detection probe arm (300) to move from the left side of the lens to the right side of the lens, and then from the right side of the lens to the left side of the lens; Step 4: During movement, the second joint motor (325) drives the camera probe (343) to rotate according to the curvature of the lens surface, and after obtaining image information of the lens surface, observe whether the lens has appearance defects.
