Description

Technical Field

[0001] This invention relates to the field of optical lens inspection, specifically to an optical lens appearance defect inspection system. Background Technology

[0002] Optical lens defect detection is a crucial step in ensuring the quality of optical lenses. By detecting defects on the surface and subsurface of lenses, the imaging accuracy, durability, and reliability of optical systems can be improved. To facilitate the detection of visual defects in optical lenses, a detection system is required. The "Apparatus and Method for Detecting Defects in Eyeglass Optical Lenses" disclosed in application number "202211031218.4" represents an increasingly mature technology. Its innovation lies in solving the comprehensive technical challenge of detecting defects such as bubbles, scratches, and pitting in power lenses, thereby establishing an industry-leading standard. This invention establishes a simple and unified quantitative standard for detecting three different types of physical defects by solely detecting scattered light. This makes automatic detection of physical defects in eyeglass lenses possible, enabling fully automated monitoring of both surface and internal defects, thus improving production efficiency. The invention is simple to set up, low in cost, and highly sensitive, with a 100% detection rate. Operators only need to re-inspect lenses that were mistakenly detected as defects due to removable surface dirt. Typically, only about 3% of lenses require re-inspection. Therefore, this invention... The system significantly reduces labor intensity and improves efficiency while avoiding unnecessary waste. However, the system has several drawbacks: While the scanning system and photoelectric sensors effectively detect defects in optical lenses, the system is not suitable for comprehensive inspection of appearance, diameter, and other parameters. Therefore, a more versatile system is needed to facilitate multi-angle inspection. Furthermore, the system's height is not easily adjustable, hindering usability. A more user-friendly system is also necessary. Additionally, the system's shock absorption is insufficient, impacting its lifespan. Therefore, a system with shock absorption to extend its lifespan is required. Finally, the system can only inspect single optical lenses, limiting continuous inspection and efficiency. Therefore, a system that enables continuous inspection and improves efficiency is essential. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. When continuously inspecting optical lenses, several optical lenses are first placed on the surface of several inspection protective pads on the upper end of a rotating ring. Then, a servo motor is started to drive the second transmission gear to rotate, which in turn drives the first transmission gear to rotate. At the same time, the first transmission gear meshes with the gear ring, and the gear ring, connecting piece and the rotating ring on the upper end can be rotated through the first transmission gear to control the cyclic rotation of several optical lenses.

The rotating assembly 200 includes a connecting ring 201 mounted on the upper end of the top plate 101. A gear ring 202 is fixedly connected to the lower end of the connecting ring 201. A first transmission gear 203 is meshed with the inner wall of the gear ring 202. A second transmission gear 204 is meshed with the side surface of the first transmission gear 203 and the middle part of the gear ring 202. A servo motor 205 is mounted on the lower end of the second transmission gear 204. A rotating ring 206 is movably mounted on the upper end face of the connecting ring 201. The top of the rotating ring 206 is movably mounted with several detection protective pads 207 in a ring array. The upper end of the second transmission gear 204 is equipped with a positioning tube 208. The inside of the positioning tube 208 is connected to a lifting shaft 209. The inside of the lifting shaft 209 is equipped with a telescopic spring 210. Several pin holes 220 are equidistantly opened on the side surface of the positioning tube 208. The end of the telescopic spring 210 is fixedly connected to a pin head 230, which is engaged inside one of the pin holes 220. The detection assembly 300 includes a mounting plate 301 mounted on the top of the lifting shaft 209. Several linear guide rails 302 are fixedly connected to the side surface of the mounting plate 301. Linear guide blocks 303 are slidably connected inside the linear guide rails 302. A rotating plate 304 is rotatably connected to the top of the mounting plate 301. Several transmission arms 305 are rotatably connected to the upper end of the rotating plate 304. The ends of the transmission arms 305 are hinged to the linear guide blocks 303. A gooseneck tube 306 is movably mounted on the upper end of the linear guide blocks 303. An observation probe 307 is fixedly connected to the end of the gooseneck tube 306.

[0019] In one specific embodiment, the shock-absorbing component 100 facilitates shock absorption and protection of the detection system, preventing damage to internal components and optical lenses due to vibration, thereby extending its service life. Simultaneously, the rotating component 200 not only facilitates cyclic rotation of the optical lenses, improving detection efficiency, but also allows for height adjustment of the detection system, enhancing its ease of use. Finally, the detection component 300 enables omnidirectional detection of the optical lenses, further enhancing the system's practicality. In use, several optical lenses are first... The optical lenses are placed on the surface of several detection protective pads 207 on the upper end of the rotating ring 206. Then, the servo motor 205 is started, driving the second transmission gear 204 to rotate, which in turn drives the first transmission gear 203 to rotate. Simultaneously, the first transmission gear 203 meshes with the gear ring 202, causing the gear ring 202, connecting ring 201, and the upper rotating ring 206 to rotate. This controls the cyclic rotation of several optical lenses. Then, through several observation probes 307 installed within the detection assembly 300, the appearance, height, median diameter, major diameter, and minor diameter of the optical lenses can be comprehensively inspected. Then, the control... The ability to bend the gooseneck tube 306 at will improve the comprehensiveness of the observation probe 307. Finally, by turning the rotating handle 341 to rotate the rotating plate 304 as needed, several transmission arms 305 can be supported or pulled, thereby controlling the linear guide block 303 to move along the linear guide rail 302 for observation operations at different positions, thus enhancing the practicality of the detection system. As the rotating assembly 200 rotates, it applies pressure to the top plate 101. When the top plate 101 presses down, the pressure is transmitted to several mounting blocks 102. Several dampers 103, in conjunction with shock-absorbing springs 104, can provide shock absorption protection for the top plate 101, thereby preventing damage to the rotating assembly. To prevent damage to component 200 and detection component 300 caused by vibration, and to extend the service life of the detection system, when adjusting the height of the detection system, simply control the lifting shaft 209 to move up and down along the positioning tube 208. This allows control of the telescopic spring 210 and pin head 230 installed inside the lifting shaft 209 to move up and down along the positioning tube 208. When the telescopic spring 210 coincides with the pin holes 220 at different positions on the side surface of the positioning tube 208, the telescopic spring 210 will pop out the pin head 230 and engage it inside the pin holes 220 at different heights on the surface of the positioning tube 208. This allows for adjustment of the height of the detection component 300, thereby improving the ease of use of the detection system.

[0020] Please see Figures 2-4 The top of the top plate 101 is provided with a circular groove 111, and the bottom of the circular groove 111 is provided with an embedding groove 112. The first bearing 113 is installed inside the embedding groove 112, and the lower end of the first transmission gear 203 is rotatably connected to the inside of the first bearing 113.

The limiting shafts 121 are inserted into the limiting holes 122. The opposite surfaces of the mounting blocks 102 and the support blocks 105 are provided with connecting screw holes 123. The upper and lower ends of the damper 103 are fixedly connected with connecting bolts 124, and the connecting bolts 124 are threaded into the connecting screw holes 123.

[0023] In one specific embodiment, the limiting shaft 121 is inserted into the limiting hole 122, which improves the ease of disassembly and replacement of the mounting block 102.

[0025] In one specific embodiment, the insertion shaft 213 is inserted into the second bearing 212. When the second transmission gear 204 rotates, it can prevent the positioning tube 208 from rotating, thereby improving the detection stability of the detection component 300 on the optical lens.

[0026] Please see Figures 2-8 A third bearing 221 is fitted on the side surface of the toothed ring 202. The third bearing 221 is installed inside the circular groove 111. Several arc-shaped grooves 222 are opened at the upper ends of both the connecting ring 201 and the toothed ring 202.

[0027] In one specific embodiment, the third bearing 221 is installed inside the circular groove 111, thereby reducing the rotational friction of the gear ring 202 and improving the smoothness of rotation.

[0028] Please see Figures 5-8 The upper end of the rotating ring 206 is fixedly connected with several first magnetic absorbing pieces 231 in a ring array, and the lower end of several detection protective pads 207 is fixedly connected with second magnetic absorbing pieces 232. The second magnetic absorbing pieces 232 are magnetically connected to the first magnetic absorbing pieces 231.

[0029] In one specific embodiment, the first magnetic absorbing piece 231 and the second magnetic absorbing piece 232 are magnetically connected, which not only facilitates the quick installation of the detection protective pad 207 and ensures stability, but also allows for quick disassembly and assembly, improving the convenience of disassembly and replacement of each component.

[0030] Please see Figure 9 and Figure 10 The top of the mounting plate 301 has a rotating hole 311, and the lower end of the rotating plate 304 is fixedly connected to a rotating rod 312, which is rotatably connected inside the rotating hole 311.

[0031] In one specific embodiment, the rotating rod 312 is rotatably connected inside the rotating hole 311, thereby improving the smoothness of rotation of the rotating plate 304.

[0032] Please see Figure 9 and Figure 10 Each of the linear guide blocks 303 has a fastening screw hole 321 at its upper end. The end of the gooseneck tube 306 away from the observation probe 307 is fixedly connected to a fastening bolt 322, which is threaded into the inside of the fastening screw hole 321.

[0033] In one specific embodiment, the fastening bolt 322 is threaded into the fastening bolt hole 321, which can enhance the installation tightness and ease of disassembly between the gooseneck tube 306 and the linear guide block 303.

[0034] Please see Figure 9 and Figure 10 The upper ends of several linear guide blocks 303 are fixedly connected to a first hinge shaft 331, the top of the rotating plate 304 is fixedly connected to several second hinge shafts 332, and the two ends of several transmission arms 305 are provided with hinge holes 333. The first hinge shaft 331 and the second hinge shaft 332 are both hinged inside the hinge holes 333.

[0035] In one specific embodiment, the first hinge shaft 331 and the second hinge shaft 332 are hinged inside the hinge hole 333, which can improve the smoothness of the rotation of the transmission arm 305 for angle adjustment.

[0036] Please see Figure 9 and Figure 10 The upper end of the rotating plate 304 is fixedly connected to the rotating handle 341, and the side surface of the rotating handle 341 is provided with anti-slip texture.

[0037] In one specific embodiment, rotating the handle 341 can rotate the rotating plate 304, thereby improving the ease of movement of the linear guide block 303.

[0038] Working Principle: In use, several optical lenses are first placed on the surface of several detection protective pads 207 on the upper end of the rotating ring 206. Then, the servo motor 205 is started, which drives the second transmission gear 204 to rotate, thereby driving the first transmission gear 203 to rotate. At the same time, the first transmission gear 203 and the gear ring 202 mesh and connect. Through the first transmission gear 203, the gear ring 202, the connecting ring 201 and the upper rotating ring 206 can be rotated, thereby controlling the cyclic rotation of several optical lenses. At the same time, several observation probes 307 set in the detection component 300 can perform all-round detection operations on the appearance, height, median diameter, major diameter and minor diameter of the optical lenses. Subsequently, controlling the gooseneck tube 306 to bend freely can improve the detection comprehensiveness of the observation probes 307. Then, as needed, the rotating handle 341 is turned to rotate the rotating plate 304, thereby supporting or pulling several transmission arms 305, so as to control the linear guide block 303 to move along the linear guide rail 302. By performing observation operations at different positions, the practicality of the detection system can be enhanced. As the rotating component 200 rotates, it applies pressure to the top plate 101. When the top plate 101 presses down, the pressure is transmitted to several mounting blocks 102. Through several dampers 103 and shock-absorbing springs 104, the top plate 101 can be protected from vibration, thereby avoiding damage to the rotating component 200 and the detection component 300, and thus extending the service life of the detection system. When the detection system is height adjusted, the lifting shaft 209 can be controlled to move up and down along the positioning tube 208, thereby controlling the telescopic spring 210 and pin head 230 installed inside the lifting shaft 209 to move up and down along the positioning tube 208. When the telescopic spring 210 coincides with the pin holes 220 at different positions on the side surface of the positioning tube 208, the telescopic spring 210 pops out the pin head 230 and engages it in the pin holes 220 at different heights on the surface of the positioning tube 208, thereby adjusting the height of the detection component 300 and improving the ease of use of the detection system.
