Description

Technical Field

[0001] This utility model belongs to the field of optical lens testing technology, and specifically relates to an optical lens testing stage. Background Technology

[0002] In the field of optics, optical lenses, as core components, are widely used in various optical instruments, equipment, and systems, such as camera lenses, microscopes, telescopes, and laser equipment. Their quality directly determines the key performance indicators of optical systems, such as imaging quality, resolution, and luminous flux. With the rapid development of science and technology, optical technology is constantly advancing towards higher precision, higher resolution, and larger apertures, and the quality requirements for optical lenses are becoming increasingly stringent. In the manufacturing process of optical lenses, every step, from the selection of raw materials and the control of processing technology to the quality inspection of finished products, is crucial. Among them, quality inspection, as the final checkpoint, can promptly detect defects and problems in lenses, ensuring that only qualified products enter the market. Currently, there are various methods for testing optical lenses. Based on different optical principles, the quality of lenses is evaluated by measuring their optical parameters, such as dispersion, polarization, focal length, and transmittance.

[0003] However, current optical lens testing stations typically only have a single light source. When a lens needs to be tested for multiple purposes, it is necessary to transfer the lens to equipment with different light sources for testing, which is a rather cumbersome operation. During the transfer process, the lens may be damaged, causing considerable inconvenience to optical lens testing. Therefore, the applicant proposes an optical lens testing station to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an optical lens inspection stage, which is equipped with multiple switchable light sources. It can switch to a specific light source according to the inspection requirements, which facilitates the inspection of various characteristics of the lens without the need to transfer the lens. This effectively simplifies the operation process and avoids damage to the lens during the transfer process, bringing more convenience to the inspection of optical lenses.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An optical lens inspection stage, comprising:

[0007] The testing mechanism and the placement mechanism mounted on top of the testing mechanism;

[0008] The testing mechanism includes a workbench, a testing arm is fixedly installed on the top of the workbench, and a testing camera is fixedly installed on the bottom of the testing arm.

[0028] Example 1:

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an optical lens testing stage includes:

[0030] The testing mechanism 1 and the placement mechanism 2 mounted on top of the testing mechanism 1;

[0031] The testing mechanism 1 includes a workbench 13, a testing arm 11 is fixedly installed on the top of the workbench 13, and a testing camera 12 is fixedly installed on the bottom of the testing arm 11.

[0032] The placement mechanism 2 includes a fixed box 21 fixedly installed on the top of the workbench 13. Inside the fixed box 21, a turntable 26 is rotatably installed via a shaft 212. Multiple light sources 210 arranged in a circular array are fixedly installed on the top of the turntable 26. An arc-shaped block 27 is slidably installed on the outer periphery of the turntable 26. A label 28 corresponding to the light source 210 is affixed to the top of the arc-shaped block 27. A placement rack 22 corresponding to the light source 210 is fixedly installed on the top of the fixed box 21.

[0033] As can be seen from the above, when in use, the lens to be tested is placed in the placement rack 22, and the light source 210 generates a light source to illuminate the lens. The detection camera 12 can capture images of bubbles and cracks in the lens. When the light source needs to be switched, the turntable 26 is rotated, which can drive multiple light sources 210 to rotate synchronously. The required light source 210 can be switched to correspond to the placement rack 22. The specific light source can be switched according to the detection requirements. By illuminating the lens with different types of light sources, it is convenient to detect various characteristics of the lens such as dispersion, polarization, focal length, and transmittance without the need to transfer the lens. This effectively simplifies the operation process and avoids damage to the lens during the transfer process, bringing more convenience to the detection of optical lenses.

[0034] During the process of switching the light source 210 by rotating the turntable 26, the arc block 27 can be moved along the inner wall of the fixing box 21. When the arc block 27 corresponding to the light source 210 moves to the position corresponding to the placement rack 22, the arc block 27 and the label 28 can extend out of the fixing box 21. Through the name of the corresponding light source 210 written on the label 28, the staff can intuitively understand the type of the light source 210 being switched, and can switch to a specific light source according to the testing needs, thus improving the usage effect.

[0035] Depend on Figure 4 It can be seen that a light shield 211 is fixedly installed on the top of the turntable 26, and the light shield 211 surrounds the light source lamp 210.

[0036] As can be seen from the above, the light shield 211 can conveniently block the light source emitted by the light source 210, so that the light source of the light source 210 only shines upward, avoiding mutual interference between the light sources of adjacent light sources 210, and improving the detection effect of the lens.

[0037] For details, please refer to Figure 3 As shown, a support ring 23 is fixedly installed on the inner wall of the placement rack 22, and retrieval ports 24 are opened at the front and rear ends of the placement rack 22.

[0038] As can be seen from the above, by placing the lens into the placement rack 22, the edge of the lens can be supported by the support ring 23, and the two sides of the lens can be exposed through the retrieval port 24, so that the staff can easily pick up and place the lens.

[0039] For details, please refer to Figure 3 As shown, the top of the fixing box 21 is provided with a light-emitting port 25, which corresponds to the placement rack 22 and the light source 210.

[0040] As can be seen from the above, the light source 210 can easily emit light through the light outlet 25 to illuminate the lens inside the mounting frame 22, which facilitates the inspection and observation of the lens.

[0041] Example 2:

[0042] refer to Figure 4 and Figure 5 As shown, an extension opening 215 is provided on one side of the fixing box 21, and the extension opening 215 corresponds to the arc-shaped block 27.

[0043] As can be seen from the above, the extension port 215 allows the arc-shaped block 27 of the corresponding light source 210 to extend out of the fixing box 21, and the label 28 can extend out of the fixing box 21 at the same time, so that the staff can observe the name of the corresponding light source 210 written on the label 28.

[0044] refer to Figure 4 As shown, the turntable 26 and the arc block 27 are slidably mounted together by a slide rod 29. The turntable 26 has a sliding groove 213 for the slide rod 29 to slide in, and a thrust spring 214 is fixedly installed between the sliding groove 213 and the slide rod 29.

[0045] As can be seen from the above, by sliding the slide bar 29 along the slide groove 213, the arc-shaped block 27 can extend and retract. When the turntable 26 rotates, the arc-shaped slope of the outer edge of the arc-shaped block 27 can be used to squeeze the extension opening 215, which can force the arc-shaped block 27 to retract into the fixed box 21, so that the arc-shaped block 27 can move along the inner wall of the fixed box 21. The thrust spring 214 can generate a thrusting force on the slide bar 29. When the arc-shaped block 27 moves to the extension opening 215, it can push the arc-shaped block 27 into the extension opening 215, so that the label 28 is exposed outside the fixed box 21, which makes it convenient for the staff to see the name of the light source 210 at the corresponding position and to switch between light sources 210 with multiple names.

[0046] refer to Figure 2 and Figure 5 As shown, the shaft 212 extends to the bottom of the worktable 13, and an adjustment handle 14 is rotatably mounted on the bottom of the worktable 13. The adjustment handle 14 and the shaft 212 are connected by a transmission belt 15.

[0047] As can be seen from the above, by rotating the adjustment handle 14, the transmission belt 15 can drive the shaft 212 to rotate. The shaft 212 and the turntable 26 are fixedly connected. The rotation of the shaft 212 can drive the turntable 26 to rotate, which facilitates the switching operation of the light source 210.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
