Description

Technical Field

[0001] This utility model relates to the field of lens testing technology, and in particular to an optical lens testing platform. Background Technology

[0002] Automotive optical lenses refer to various optical lenses used inside or outside automobiles. They are primarily used to improve driver visibility, enhance safety, and provide a comfortable driving environment. There are many types of automotive optical lenses, including camera lenses and optical sensor lenses.

[0003] Lens processing also requires light transmittance testing to ensure lens quality. For example, Chinese Patent Publication No. CN216899559U discloses a device for testing the light transmittance of optical lenses, including a body. A testing head is fixedly installed at the top of the body, and support feet are fixedly installed at the four corners of the bottom of the body. Sliding seats are symmetrically fixedly installed at the top of the body, with an adjusting screw rotatably installed on the inner wall of one end of each sliding seat. Sliding blocks are symmetrically slidably installed on the inner side of each sliding seat. An adjusting motor is fixedly installed at one side of each sliding seat at the top of the body. This belongs to the field of testing equipment technology. This utility model has a scientifically sound and reasonable structure. Through the alternating testing and installation mechanism, it reduces the time wasted on disassembling and assembling lenses during testing, increasing the efficiency of lens testing. The testing and positioning mechanism facilitates positioning and pressing of the lens, reducing displacement caused by external vibrations and improving the stability of the lens after placement.

[0004] In practice, the lens is elastically pressed by the pressing ring plate to achieve the positioning function. However, the pressing ring plate needs to be driven by a hydraulic rod and can only position one lens at a time, resulting in high inspection costs and low inspection efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 An optical lens inspection platform includes an inspection table 1, an inspection lens 3 is mounted on the top of the inspection table 1 via a drive mechanism 2, an inspection light source 7 is mounted below the inspection lens 3, and an inspection disk 5 is mounted via an intermittent mechanism 4, the intermittent mechanism 4 being used to intermittently drive the inspection disk 5 to rotate.

[0024] The detection disk 5 has several detection slots 51 distributed around its outer circumference. Each detection slot 51 is equipped with a stop assembly 6, which holds the lens within the detection slot 51.

[0025] In some embodiments, the drive mechanism 2 drives the support plate to move in a cross shape through two sets of ball screw assemblies. The detection lens 3 is fixedly connected to the bottom of the support plate. The detection lens 3 is a light transmittance detection lens in the prior art. The detection lens 3 is electrically connected to the detection terminal and is used to cooperate with the detection lamp source 7 to perform light transmittance detection on the lens.

[0026] Furthermore, the intermittent mechanism 4 includes a support rod 41, which is fixedly connected to the top of the detection table 1. A support plate 42 is fixedly connected to the top of the support rod 41, and a grooved wheel 43 is rotatably connected to it. The grooved wheel 43 has several recesses 431 distributed around its outer circumference, and a guide groove 432 is provided between adjacent recesses 431 on both sides. The detection disk 5 is fixedly connected to the top of the grooved wheel 43.

[0027] Furthermore, the motor 45 is fixedly connected to the bottom of the support plate 42, and the shaft end of the motor 45 is provided with a support rod 41 and fixedly connected with a drive component 46;

[0028] The driving component 46 has a circular structure, and a relief groove 461 is provided on the periphery of the driving component 46, and a stop rod 47 corresponding to the relief groove 461 is fixed at the bottom.

[0029] More specifically, the drive member 46 is rotatably connected in the recess 431, and the drive member 46 also avoids the grooved wheel 43 through the relief groove 461. The protrusion structure 44 provided at the free end of the push rod 47 is slidably connected in the guide groove 432.

[0030] It should be added that the structure of the intermittent mechanism 4 can be referred to the Geneva mechanism in the prior art. In specific operation, the rotating push rod 47 extends the protruding structure 44 into the guide groove 432. Then, the push rod 47 drives the groove wheel 43 to rotate during its rotation, so that the groove wheel 43 rotates to a certain extent, thereby achieving the function of intermittently driving the detection disk 5 to rotate.

[0031] Specifically, the detection slot 51 is rotated to correspond with the detection lens 3 to ensure that when the drive is in place, the lens corresponds to the detection lens 3 and the detection light source 7.

[0032] In general, the stop assembly 6 includes a stop block 61, the detection groove 51 connects the outer edge of the detection disk 5 and the upper and lower sides, and the upper and lower sides of the detection groove 51 extend laterally to form extension portions 52. The detection groove 51 has a receiving groove 53 on the opening side, and the stop block 61 is rotatably connected in the receiving groove 53 by a pin and a spring 62. The detection groove 51 is rotated to correspond with the detection lens 3.

[0033] Finally, the top of the detection disk 5 is provided with an arc groove 63, which is connected to the receiving groove 53. An unlocking rod 64 is slidably connected in the arc groove 63. The bottom of the unlocking rod 64 is threadedly connected to the abutment block 61, and the protruding part at its top abuts against the detection disk 5.

[0034] In this embodiment, the lenses can be placed one by one between the upper and lower extensions 52. The upper and lower extensions 52 are attached with lens cloth on opposite sides to prevent the lenses from being scratched. The abutment 61 has an arc-shaped structure on the side near the lens, and a flexible block can be provided on the side of the abutment 61 near the lens to fix the lens by elastic pressing.

[0035] Specifically, the unlocking lever 64, by pressing against the detection disc 5, prevents the stop block 61 from moving freely and facilitates the loading and unloading of lenses.

[0036] Working method: During operation, the lens is placed in the detection slot 51 by rotating the release lever 64 to rotate the stop block 61. The stop block 61 is driven by the spring 62 to reset the release lever 64. At this time, tightening the release lever 64 can prevent the stop block 61 from moving freely.

[0037] Then, the motor 45 drives the drive component 46 to rotate, and the rotating push rod 47 extends the protruding structure 44 into the guide groove 432. Then, the push rod 47 drives the groove wheel 43 to rotate during its rotation, so that the groove wheel 43 rotates to a certain extent, thereby achieving the function of intermittently driving the detection disk 5 to rotate.

[0038] The detection lens 3, under the action of the drive mechanism 2, works in conjunction with the detection lamp source 7 to detect the lens. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
