Description

Technical Field

[0001] The utility model relates to the technical field of optical lens detection, and more specifically, to an optical lens thickness detection platform. Background Art

[0002] The glass used for optical lenses is a mixture of high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasound to remove bubbles, and then slowly cooled over a long period of time to prevent internal stress in the glass block. The cooled glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to become optical lens blanks. In recent years, with the development of optical products, the application scope of optical lenses has continued to expand. For example, optical lenses can be seen in digital cameras, smart phones, laptops and other devices with camera functions.

[0003] The detection device detects the thickness of the optical lens through two test clamps. This detection method can only detect the thickness of the thickest part of the optical lens, and the detection result is inaccurate. At the same time, this method can only detect plane optical lenses and is not convenient for detecting concave mirrors and convex mirrors.

[0004] After searching, a Chinese patent with application number CN202121287776.8 discloses an optical lens thickness detection device, which can detect the thickness of multiple positions of optical lenses of different shapes, thereby improving the accuracy of the detection results of the device and the applicability of the device.

[0005] When the above-mentioned optical lens thickness detection device is actually used, the optical lens may move or rotate during the measurement process due to external force, vibration or improper operation, which may make the optical lens more susceptible to damage during the measurement process, and at the same time cause errors in the measurement data, reducing the measurement accuracy.
