Description

Technical Field

[0001] This utility model relates to the field of optical lens inspection technology, and in particular to a multi-angle illumination device for detecting surface defects of optical lenses. Background Technology

[0002] The production process of large-size optical lenses requires multiple light irradiation tests to quantitatively evaluate parameters such as local surface shape and surface roughness, ensuring that they meet design standards. When testing large-size optical lenses, a flexible and stable irradiation device is needed to irradiate the optical lenses so as to complete the testing of various local surfaces. However, the light source position of existing light irradiation devices is fixed, and the irradiation position and angle cannot be flexibly adjusted, or the stability is insufficient, thereby reducing the testing effect. In view of this, this utility model is proposed. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a multi-angle illumination device for detecting defects on the surface of optical lenses, which has the effect of flexible adjustment of the illumination angle.

[0004] The technical solution adopted by this utility model is as follows: It includes a mounting platform, with a rubber pad fixedly mounted on the lower end of the platform. A rotating assembly is mounted on the platform, and an I-shaped slide rail with a quarter-arc shape is fixedly mounted on the rotating assembly. A position adjustment assembly is snapped onto the slide rail, and multiple self-locking telescopic rods are mounted on the lower end of the position adjustment assembly. A mounting plate is fixedly mounted on the lower end of the multiple self-locking telescopic rods, and an irradiator is fixedly mounted on the lower end of the mounting plate. In use, the structure is first placed at the location of use. The irradiator emits light to illuminate and detect an optical lens placed on the mounting platform. During the detection process, the rotating assembly drives the slide rail, the position adjustment assembly, and the irradiator to rotate, thereby adjusting the position of the irradiator laterally. Simultaneously, the position adjustment assembly moves on the slide rail, thereby adjusting the position of the irradiator longitudinally. This allows for flexible adjustment of the angle of the light emitted by the irradiator, improving the accuracy of the detection.

[0005] Preferably, in order to enable the rotating ring to rotate on the mounting platform, an annular rotating groove is fixedly installed at the upper end of the mounting platform. The annular rotating groove is T-shaped. The rotating assembly includes a rotating ring, the lower part of which is engaged in the annular rotating groove. A driven conical toothed ring is fixedly installed on the upper outer side of the rotating ring, and the driven conical toothed ring is located above the mounting platform.

[0006] Preferably, in order to drive the rotating ring to rotate, the rotating assembly further includes a control motor, which is fixedly installed on one side of the upper end of the mounting platform and located on one side of the rotating ring. The output end of the control motor is fixedly installed with a driving bevel gear, which meshes with the driven bevel gear ring.

[0007] Preferably, in order to install the multi-section self-locking telescopic rod on the position adjustment assembly so that the irradiator can be moved by the position adjustment assembly, the position adjustment assembly includes an adjustment box located inside the slide rail, and the multi-section self-locking telescopic rod is fixedly installed at the lower end of the adjustment box.

[0008] Preferably, in order to enable the position adjustment component to move on the slide rail and thereby adjust the position of the position adjustment component, the upper end of the adjustment box is provided with a moving groove on both sides. The two ends of the moving groove are slidably engaged with a sliding block. The upper end of the sliding block is fixedly installed with a fixed shaft. The upper part of the fixed shaft is fixedly installed with a miniature self-locking hub motor. The outer side of the miniature self-locking hub motor is fixedly installed with a moving wheel. The moving wheel is engaged with both sides of the slide rail, and the outer side of the moving wheel is fixedly installed with an anti-slip pad. The outer side of the anti-slip pad is in close contact with the slide rail.

[0009] Preferably, in order to drive the bidirectional threaded rod to rotate, thereby driving the sliding block to move in the moving groove, and thus enabling the position adjustment component to be installed on the slide rail, a micro motor is fixedly installed on both sides of one outer end of the adjustment box, and a bidirectional threaded rod is fixedly installed on the output end of the micro motor. The bidirectional threaded rod is rotatably engaged in the moving groove. The sliding block is I-shaped, and the sliding block is threadedly sleeved on both ends of the bidirectional threaded rod.

[0010] The beneficial effects of this utility model are: the rotating component can drive the slide rail to rotate, thereby driving the position adjustment component and the irradiator to rotate. At the same time, the position adjustment component can move on the slide rail, thereby driving the irradiator to move, so that the irradiator can adjust the irradiation position, thereby adjusting the angle of the light, improving the flexibility and stability of irradiation detection.

A position adjustment component 5 is snapped onto the slide rail 4. A multi-section self-locking telescopic rod 6 is installed at the lower end of the position adjustment component 5. A mounting plate 7 is fixedly installed at the lower end of the multi-section self-locking telescopic rod 6. An irradiator 8 is fixedly installed at the lower end of the mounting plate 7. In use, the device is first placed at the location of use. The irradiator 8 can emit light to illuminate and detect the optical lens placed on the mounting platform 1. During the detection process, the rotating component 3 can drive the slide rail 4, the position adjustment component 5, and the irradiator 8 to rotate, thereby adjusting the position of the irradiator 8 laterally. At the same time, the position adjustment component 5 can move on the slide rail 4, thereby adjusting the position of the irradiator 8 longitudinally. This allows the angle of the light emitted by the irradiator 8 to be flexibly adjusted, improving the stability of the detection.

[0019] As a technical optimization solution of this utility model, specifically as follows: Figure 4As shown, an annular rotating groove 9 is fixedly installed on the upper end of the mounting platform 1. The annular rotating groove 9 is T-shaped. The rotating assembly 3 includes a rotating ring 301. The lower part of the rotating ring 301 is engaged in the annular rotating groove 9, and a driven conical toothed ring 302 is fixedly installed on the outer side of the upper part of the rotating ring 301. The driven conical toothed ring 302 is located above the mounting platform 1. The rotating assembly 3 also includes a control motor 303. The control motor 303 is fixedly installed on one side of the upper end of the mounting platform 1, and the control motor 303 is located on one side of the rotating ring 301. A driving bevel gear 304 is fixedly installed at the output end of the control motor 303. The driving bevel gear 304 meshes with the driven conical toothed ring 302. In use, the control motor 303 can drive the driving bevel gear 304 to rotate, thereby driving the rotating ring 301 to rotate through the driven conical toothed ring 302, thereby driving the slide rail 4 to rotate.

[0020] As a technical optimization solution of this utility model, specifically as follows: Figure 5 As shown, the position adjustment assembly 5 includes an adjustment box 501, which is located inside the slide rail 4. A multi-section self-locking telescopic rod 6 is fixedly installed at the lower end of the adjustment box 501. Moving slots 502 are provided on both sides of the upper end of the adjustment box 501. Sliding blocks 503 are slidably engaged at both ends of the moving slots 502. Fixed shafts 504 are fixedly installed on the upper ends of the sliding blocks 503. Miniature self-locking hub motors 505 are fixedly installed on the upper parts of the fixed shafts 504. Moving wheels 506 are fixedly installed on the outer sides of the miniature self-locking hub motors 505. The moving wheels 506 are engaged on both sides of the slide rail 4, and anti-slip pads 507 are fixedly installed on the outer sides of the moving wheels 506, with the outer sides of the anti-slip pads 507 in close contact with the slide rail 4. Miniature motors 508 are fixedly installed on both sides of one outer end of the adjustment box 501. The output end of the irradiator 8 is fixedly equipped with a bidirectional threaded rod 509, which is rotatably engaged in the moving groove 502. The sliding block 503 is I-shaped and threaded onto both ends of the bidirectional threaded rod 509. In use, the position adjustment component 5 is placed inside the slide rail 4, and the moving wheels 506 are located on both sides of the slide rail 4. Then, the micro motor 508 drives the bidirectional threaded rod 509 to rotate, thereby driving the sliding block 503 to move in the moving groove 502, so that the moving wheels 506 can be engaged on the slide rail 4, thereby engaging the position adjustment component 5 on the slide rail 4. During use, the micro self-locking hub motor 505 can drive the moving wheels 506 to rotate, thereby driving the position adjustment component 5 to move on the slide rail 4, so that the position of the irradiator 8 can be adjusted longitudinally.

[0021] It is understood that the stable and adjustable illumination device provided in this application is specifically designed for surface inspection during the processing of large-sized optical components, such as detecting local surface shapes, surface scratches, pitting defects, etc. The selection of illuminators (e.g., color temperature) is diverse, and the observed patterns are easy to photograph and record. Figure 2 In this device, the portion of the mounting platform 1 located in the center of the rotating groove 9 can be a solid platform for placing the inspected part, or it can be hollowed out. When the inspected part is large, the hollowed-out design allows the entire device to be lifted and placed over the inspected part to inspect the surface quality of the optical lens being processed. Because the device provided in this application has a stable structure (compared to simpler methods such as gooseneck lamps and handheld lighting), it can ensure good inspection results.
