Embodiment Construction

[0029] The following specific examples illustrate the present invention in further detail.

[0030] Such as Figure 1-7 As shown, a lens detection device provided by the present invention is mainly used to detect the center thickness and outer diameter error of the lens, including a first detection device for detecting the lens center thickness and a second detection device for detecting the lens outer diameter error device.

[0031] Such as Figure 1~2 As shown, the first detection device and the second detection device of this embodiment are all fixed on the base 1, wherein the first detection device is located directly above the carrier for carrying the lens 9, and the second detection device is located around the carrier . The first detection device includes a fixed bracket 10 fixed on the base 1, on which a guide rod 12 and a screw 13 arranged vertically are installed, and the screw 13 is driven by a motor on the fixed bracket 10 to rotate around its own axis. The gui...

Abstract

The invention discloses a lens detection device. The lens detection device comprises a first detection device, the lens detection device is used for detecting the center thickness of a lens and is arranged above a carrier, and the lens detection device further comprises a second detection device which is arranged on the periphery of the carrier and is used for detecting the outer diameter error ofthe lens, the second detection device comprises more than or equal to four pneumatic displacement sensors, the pneumatic displacement sensors are positioned on the periphery of the carrier and are arranged at intervals along the circumferential direction of the carrier, each pneumatic displacement sensor is a displacement sensor with a detection end which can move along the radial direction of the lens to until to be in contact with the edge of the lens, and each pneumatic displacement sensor is radially adjustably connected to the base through a mounting device. According to the invention, the center thickness and the outer diameter error of the lens can be detected at the same time, damage to the lens is avoided in the detection process, the detection is accurate and efficient, a largeamount of manpower and material resources are saved, and the lens detection device has great popularization value.

Description

technical field [0001] The invention relates to the field of lens testing equipment, in particular to a lens testing device. Background technique [0002] Lenses are commonly used optical components in optical devices and are used in a wide range of applications. Because it is a precision optical component, it requires high processing accuracy. After the processing is completed, the outer diameter and center thickness of the lens are two important parameters. Whether these parameters are processed accurately or not directly determines the quality of the processing. The traditional detection method of lens outer diameter and central thickness is to manually detect the outer diameter and central thickness respectively. When manually detecting the outer diameter, the worker places the lens on the outer diameter detection workbench, and a pair of outer diameter probes are symmetrically arranged on the workbench, triggering the outer diameter probe to make it protrude from the p...
