Description

Technical Field

[0001] This utility model relates to the field of lens manufacturing technology, specifically to a testing device used in the production of optical lenses. Background Technology

[0002] During the lens manufacturing process, some defects are inevitable, such as scratches, air bubbles, and pitting on the lens surface. To ensure the quality of the lenses leaving the factory, defect detection is required after lens production.

[0003] According to CN221782097U, a fully automatic lens inspection device is disclosed. This technology discloses a technical solution including a processing table, a material tray, a loading mechanism, an inspection mechanism, an unloading mechanism, a transfer mechanism, and a replacement mechanism. It has the following technical effects: "The loading mechanism loads a material tray containing lenses to be inspected. The transfer mechanism first transfers the material tray containing lenses to be inspected from the loading mechanism to the inspection mechanism for inspection. Then, the material tray containing inspected lenses after inspection is transferred to the unloading mechanism for unloading. The loading mechanism, inspection mechanism, and unloading mechanism work synchronously, resulting in higher automation and inspection efficiency. The replacement mechanism automatically replaces defective lenses in the material tray of the unloading mechanism with qualified lenses, eliminating the need for manual defect removal and automatically replenishing qualified lenses, thus increasing efficiency."

[0004] Existing optical lens inspection devices typically require manual flipping of the lens or the use of multiple devices to inspect the front and back sides separately when inspecting double-sided defects. This not only increases the complexity of operation, but also easily leads to secondary damage to the lens surface or positioning deviation due to manual intervention, affecting the inspection accuracy and efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an inspection device for optical lens production. It improves efficiency through automated flipping and double-sided inspection, while utilizing a detachable tray and buffer design to fix the lenses, avoiding damage and simplifying operation, thus achieving efficient and accurate non-destructive testing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a testing device for optical lens production, comprising a processing table and a lens workpiece, wherein a testing mechanism is provided on the processing table for testing the surface of the lens workpiece, and the testing mechanism includes:

[0007] The conveying assembly includes a conveyor fixed to the top of the processing table, on which a tray component is placed and used for positioning the lens workpiece;

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a testing device for optical lens production, including a processing table 1 and a lens workpiece 3. A testing mechanism 2 is provided on the processing table 1 for testing the surface of the lens workpiece 3. The testing mechanism 2 includes:

[0027] The conveying assembly 21 includes a conveyor 211 fixed to the top of the processing table 1, on which a tray component 212 is placed and used to position the lens workpiece 3;

[0028] Anti-deviation component 22 is disposed inside conveyor 211 and used to position pallet component 212;

[0029] The flipping assembly 23 includes a frame 231 fixed to the front end of the conveyor 211. An electric slide 232 is installed inside the frame 231. A second dual-axis cylinder 233 is fixed on the slider of the electric slide 232. A mounting bracket 234 is fixed to the output end of the second dual-axis cylinder 233. A servo motor 235 is fixed to the front end of the mounting bracket 234. A rotating frame 236 is fixed to the output end of the servo motor 235. A third dual-axis cylinder 237 is fixed to both ends of the rotating frame 236. A clamping arm 238 is fixed to the output end of the third dual-axis cylinder 237.

[0030] In this embodiment, the output end of the third dual-axis cylinder 237 at both ends drives the clamping arm 238 to clamp the tray component 212 lifted by the anti-deviation component 22. Then, the second dual-axis cylinder 233 controls the tray component 212 to rise slightly. Then, the electric slide table 232 controls the tray component 212 to move forward and move away from the top of the conveyor 211. Then, the servo motor 235 controls the tray component 212 to rotate 180°. Finally, the above steps are repeated to reset the tray component 212 and put it back on the conveyor 211. This realizes the automation of double-sided inspection of the lens workpiece 3, reduces manual intervention, and improves efficiency.

[0031] Specifically, the anti-deviation component 22 also includes three bases 221 fixed inside the conveyor 211. A first dual-axis cylinder 222 is fixed on the top of the base 221. The output end of the first dual-axis cylinder 222 is fixed to a bracket 224 via a slide 223. A calibration head 225 is fixed on the top of the bracket 224.

[0032] In this embodiment, the slide 223 is driven by the output end of the first dual-axis cylinder 222 to drive the bracket 224, so that the tray component 212 on the conveyor 211 can be lifted by the bracket 224.

[0033] Specifically, the pallet component 212 includes a lower pallet 2121 placed on the conveyor 211, and an upper pallet 2122 installed on the upper end of the lower pallet 2121. Both the lower pallet 2121 and the upper pallet 2122 have several arrayed positioning slots 2123 inside for fixing the lens workpiece 3. A rubber ring 2126 is fixed to the inner wall of the positioning slot 2123.

[0034] In this embodiment, the lens workpiece 3 is placed between the positioning slot 2123 on the lower tray 2121 and the positioning slot 2123 on the upper tray 2122, and then the lower tray 2121 and the upper tray 2122 are fixed, thereby fixing the lens workpiece 3. In addition, the rubber ring 2126 prevents wear or scratches on the fixed lens workpiece 3.

[0035] Specifically, the pallet component 212 also includes mounting holes 2124 at the four corners inside the lower pallet 2121 and the upper pallet 2122, and the lower pallet 2121 and the upper pallet 2122 are fixed together with bolts through the mounting holes 2124.

[0036] In this embodiment, the lower tray 2121 and the upper tray 2122 can be disassembled and assembled, which facilitates the loading and unloading of the lens workpiece 3.

[0037] Specifically, the tray component 212 also includes calibration holes 2125 formed on both sides inside the lower tray 2121 and the upper tray 2122.

[0038] In this embodiment, when the anti-deviation component 22 positions the tray component 212, the calibration head 225 is inserted into the calibration hole 2125.

[0039] Specifically, the testing mechanism 2 also includes a multi-axis module 24 fixed on the top of the processing table 1, and two vision lenses 25 are installed on the multi-axis module 24.

[0040] In this embodiment, the vision lens 25 on the left side of the multi-axis module 24 is used to detect one side of the lens workpiece 3 when the lower tray 2121 in the tray component 212 is facing upwards, and the vision lens 25 on the right side of the multi-axis module 24 is used to detect the other side of the lens workpiece 3 when the upper tray 2122 in the tray component 212 is facing upwards.

[0041] The working principle and usage process of this utility model are as follows: First, the lens workpiece 3 is placed between the positioning slot 2123 on the lower tray 2121 and the positioning slot 2123 on the upper tray 2122. Then, the lower tray 2121 and the upper tray 2122 are fixed to fix the lens workpiece 3. In addition, the rubber ring 2126 is used to prevent wear or scratches on the fixed lens workpiece 3.

[0042] Then, the tray component 212 containing the lens workpiece 3 is transported by the conveyor 211 to the area below the vision lens 25 on the left side of the multi-axis module 24, where the lower tray 2121 of the tray component 212 is facing upwards, and the side of the lens workpiece 3 can be detected.

[0043] After this side inspection is completed, the pallet component 212 is moved to the center of the conveyor 211. The output end of the first dual-axis cylinder 222 drives the slide 223 to move the bracket 224, so that the pallet component 212 on the conveyor 211 can be lifted by the bracket 224. Then, the output end of the third dual-axis cylinder 237 at both ends drives the clamping arm 238 to clamp the pallet component 212 lifted by the anti-deviation component 22. Then, the second dual-axis cylinder 233 controls the pallet component 212 to rise slightly. Then, the electric slide 232 controls the pallet component 212 to move forward and move away from the top of the conveyor 211. Then, the servo motor 235 controls the pallet component 212 to rotate 180°. Finally, the above steps are repeated to reset the pallet component 212 and put it back on the conveyor 211.

[0044] Finally, the pallet component 212 continues to move to the area below the vision lens 25 on the right side of the multi-axis module 24 to detect one side of the lens workpiece 3 when the lower pallet 2121 in the pallet component 212 is facing upwards; thus realizing the automation of double-sided detection of the lens workpiece 3, reducing manual intervention and improving efficiency.
