Description

Technical Field

[0001] The utility model relates to a batch inspection device for optical elements. Background Art

[0002] Optical elements usually have multiple lenses, each with two mirror surfaces. In the process of assembling optical lenses, it is necessary to measure the optical axis, that is, to measure the tilt angle between the optical lenses. The higher the assembly accuracy and the smaller the tilt angle, the better the imaging quality of the optical system. The smaller the angle between the optical axes, the better the imaging quality of the optical system.

[0003] After conventional optical lenses are produced as semi-finished products, measuring instruments are used to measure the mirror surface of each lens in turn, and most of the time, this is a single lens. Large quantities of identical lenses are placed individually in the equipment for measurement, which wastes time. Utility Model Content

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0024] like Figure 1-5 As shown, a device for batch testing of optical components is characterized in that it comprises:

[0025] The lens measuring seat 1 has a plurality of measuring holes 11 thereon, and the measuring holes 11 are stepped and sunken inwards;

[0026] A lower base 3, which is used for positioning and mounting on an external tooling;

[0027] An upper base 2 mounted on a lower base 3;

[0028] The lens measuring seat 1 is installed on the upper base 2 .

[0029] Furthermore, straight grooves 13 are provided on both sides of the measuring hole 11 of the lens measuring seat 1. The tool clamping structure is innovatively designed, and straight grooves 13 are provided on both sides of the measuring hole 11 to ensure the convenience of clamping the lens in a small space.

[0030] Furthermore, a square positioning hole 22 is provided on the upper base 2. The square positioning hole 22 cooperates with the positioning seat 12 to make the lens measuring seat 1 more accurately positioned when placed.

[0031] Furthermore, a positioning seat 12 is provided below the lens measuring seat 1 to match the positioning hole 22 , and the positioning seat 12 is in the shape of a square ring.

[0032] Furthermore, the cross section of the lower half of the positioning seat 12 is an inverted trapezoid, and the edges of the positioning seat 12 are all chamfered. The lower half of the positioning seat 12 is an inverted trapezoid, so that the positioning seat 12 can enter the positioning hole 22 better and more smoothly when the mechanical part automatically grasps and places it on the upper base 2.

[0033] Furthermore, a positioning block 31 is provided on the lower base 3, and a notch is provided below the upper base 2 and a positioning structure that cooperates with the positioning block 31. The positioning block 31 is obtuse-angled, and the positioning structure is a fastening strip 21 protruding forward. The inner side of the positioning block 31 has a snap-fitting groove 32 for the fastening strip 21 to be snapped in. The upper base 2 and the lower base 3 are positioned and fixed by the fastening strip 21 and the snap-fitting groove 32.

[0034] Furthermore, a positioning plate 4 is provided below the lower base 3 and reserved interfaces 5 are provided at the four corners of the positioning plate 4. The reserved interfaces 5 are used to align the tooling for use, and the shape of the lens measuring seat 1 is combined to ensure that the measuring fixture is placed in the same direction each time.

[0035] The lens measuring seat 1 of the present application is provided with 9 or more measuring holes 11 according to actual needs, and an innovative measuring tool is designed for measuring 9 lenses at a time, which greatly improves the measuring efficiency.
