Description

Technical Field

[0001] This invention relates to a detection device, and more particularly to an optical lens thickness detection device. Background Technology

[0002] Optical lenses are mainly used in camera equipment. After the optical lenses are manufactured, their thickness is tested before they leave the factory to ensure the quality of the manufacturing process. However, existing testing devices do not clamp the lenses during use, which can easily lead to errors and inaccurate measurement results. Therefore, it is necessary to design a new testing device.

[0003] Patent application CN211178244U, published on August 4, 2020, discloses an optical lens thickness detection device. This device includes a base for supporting the lens, a level on the base for measuring its levelness, a support mounted on the base, a long ruler on the top wall of the support, an adjusting block and a short ruler slidably mounted on the long ruler, a stop block abutting against the lens surface, and a support block connected to the stop block. The support block has a mounting component for fixing the stop block. The bottom of the adjusting block drives the short ruler to slide along the height direction of the long ruler, and the adjusting component is connected to the top of the support block. The outer wall of the long ruler has a positioning component for fixing the adjusting block and the short ruler. The long ruler has a centimeter-level scale, and the short ruler has a millimeter-level scale. In use, this device detects the thickness of the optical lens using the long and short rulers. However, the device directly places the optical lens on the top of the base for detection without clamping it, which easily causes the optical lens to move during the detection process, leading to inaccurate detection data.

[0070] Now refer to Figure 1 and Figure 9The size adjusting mechanism 11 comprises a first sliding frame 111, a second sliding frame 112, a catch 113 and a fifth compression spring 114. The right damping sliding frame 71 is welded with the second sliding frame 112 on the right side of the front and back of the right part.
