Description

Technical Field

[0001] The utility model relates to the technical field of optical glass lens detection, in particular to a device for detecting surface defects of an optical glass lens. Background Technique

[0002] Optical glass lenses need appearance detection because their quality and appearance defects directly affect the imaging quality and user experience. As an important part of optical instruments, the surface quality and appearance defects of optical glass lenses will directly affect the optical performance and visual effect. For example, defects such as scratches and pockmarks will cause light scattering, thereby affecting the imaging clarity and contrast.

[0003] For example, an optical glass lens surface defect detection device with the publication number of CN220690827U in the prior art constructs an optical glass lens surface defect detection device by setting a detection box, a placement box, an exposure lamp, a placement port, a transparent glass, a motor, a threaded rod, a threaded sleeve, an electric push rod and a CCD detection module. The glass lens can be conveniently placed through the placement port, and then the lens placed in the middle of the transparent glass is subjected to strong exposure treatment by the exposure lamp. The defects on the lens surface are revealed by the strong light irradiation. At this time, the settings of the motor, the threaded rod and the threaded sleeve can drive the CCD detection module to expand the detection range of the transparent glass, realize the detection of multiple transparent glasses, and improve the detection efficiency.

[0004] Although the above detection device has solved some existing problems, in actual use, since the glass lens is placed in the placement port for support and the defects of the glass lens are detected through the CCD detection module from above, when detecting the side, due to the occlusion of the placement box and the placement port, it cannot be detected, resulting in the need to re-detect the edge of the optical glass lens subsequently.

Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] As Figures 1 - 4 shown, it relates to a surface defect detection device for an optical glass lens, including a detection chassis 1. A machine base 2 is fixedly connected inside the detection chassis 1. A groove is opened at the top of the machine base 2. The inner wall of the groove is fixedly connected with a motor 3. A through hole is opened at the top of the machine base 2. The inner wall of the through hole is rotationally connected with the outer wall of the output shaft of the motor 3. The top of the output shaft of the motor 3 is fixedly connected with a turntable 4. Without affecting the placement of the optical glass lens, the motor 3 drives the turntable 4 to rotate slowly.

[0023] A plurality of circular grooves are formed in the outer wall of the turntable 4. Inside each of the plurality of circular grooves, a transparent acrylic circular frame 5 is rotatably connected. The transparent acrylic circular frame 5 has a high light transmittance to facilitate the shooting by the second CCD camera 14. An annular block 6 is fixedly sleeved on the outer wall of the transparent acrylic circular frame 5. A plurality of balls are rotatably embedded in the outer wall of the annular block 6. When the transparent acrylic circular frame 5 rotates, it rotates in the circular groove through the annular block 6.

[0024] A connecting column 7 is fixedly connected to the bottom of the transparent acrylic circular frame 5. A disc 8 is fixedly connected to the bottom of the connecting column 7. The connecting column 7 supports the disc 8. A rubber sleeve 9 is fixedly sleeved on the outer wall of the disc 8. An arc-shaped plate 10 is fixedly connected to the outer wall of the machine base 2. The arc-shaped plate 10 is made of metal, and the initial contact surface of the rubber sleeve 9 is processed into an arc shape to facilitate the subsequent extrusion and rotation of the rubber sleeve 9 with the arc-shaped plate 10. An opening and closing door 11 is hinged to the outer wall of the detection chassis 1. The outer wall of the arc-shaped plate 10 is pressed against the outer wall of one of the rubber sleeves 9. The overall arc of the arc-shaped plate 10 satisfies the circular movement track of the rubber sleeve 9.

[0025] A shooting mechanism is provided inside the detection chassis 1. The shooting mechanism includes an LED fill light 12, which improves the fill light effect and can be additionally installed inside the detection chassis 1. The two ends of the LED fill light 12 are fixedly connected to the inner wall of the detection chassis 1. A plurality of first CCD cameras 13 are fixedly connected inside the detection chassis 1. A plurality of second CCD cameras 14 are fixedly connected inside the detection chassis 1. The plurality of first CCD cameras 13 and the plurality of second CCD cameras 14 adopt existing conventional models.

[0026] Working principle: When in use, rotate the opening and closing door 11 outward to expose the inside of the detection chassis 1. The motor 3 operates to drive the turntable 4 to rotate. Place the optical glass lens on the top of the transparent acrylic circular frame 5. As the turntable 4 slowly rotates, it drives the optical glass lens to approach the first CCD camera 13 and the second CCD camera 14. When the rubber sleeve 9 on the disc 8 at the bottom of the transparent acrylic circular frame 5 contacts the outer wall of the arc-shaped plate 10, as the motor 3 operates, the rubber sleeve 9 is pressed against the arc-shaped plate 10. Due to the extrusion force and the rotation force of the turntable 4, the transparent acrylic circular frame 5 rotates through the annular block 6 and the plurality of balls, thereby driving the optical glass lens placed on the top of the transparent acrylic circular frame 5 to rotate. At this time, the plurality of first CCD cameras 13 shoot the edge of the optical glass lens, and the plurality of second CCD cameras 14 shoot the optical glass lens to detect whether there are defects such as scratches or pits.

[0027] It should be noted that in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the motor 3, the LED fill light 12, the first CCD camera 13, and the second CCD camera 14, which is convenient for controlling the overall operation. The specific data analysis and processing involved to further implement the control function are the method contents that those skilled in the art can achieve based on common knowledge. These method contents are not within the scope of this solution.
