Description

Technical Field

[0001] This utility model relates to the field of camera lens technology, specifically to a laser texturing device for camera lenses. Background Technology

[0002] Camera lenses are the core optical components in a camera responsible for collecting, focusing, and transmitting light. They are usually made of glass or plastic, and their shape, material, and arrangement directly affect the camera's imaging quality, field of view, and functional characteristics. Laser texturing of camera lenses is a technique that uses laser technology to process the microstructure of the lens core surface in order to reduce the reflectivity of non-optical surfaces, eliminate stray light, and improve imaging quality.

[0003] Laser texturing technology uses a high-energy pulsed laser beam to irradiate the surface of a lens core, forming micro- to sub-micron-scale microstructures (such as pits, protrusions, or disordered rough particles). These microstructures effectively reduce the reflectivity of non-optical surfaces by increasing the light scattering path, thereby reducing stray light interference. However, existing laser texturing equipment has shortcomings in terms of process integration and automation. For example, some equipment requires steps to complete the loading, inspection, processing, cleaning, and unloading processes, resulting in low production efficiency; or due to the lack of a real-time visual inspection system, it is difficult to ensure the consistency of processing quality. Therefore, laser texturing equipment for camera lenses has been proposed to solve the above problems. Utility Model Content

It solves the problem that laser texturing technology uses a high-energy pulsed laser beam to irradiate the surface of the lens core, forming micron- to submicron-scale microstructures (such as pits, protrusions, or disordered rough particles). These microstructures effectively reduce the reflectivity of non-optical surfaces by increasing the light scattering path, thereby reducing stray light interference. However, existing laser texturing equipment has shortcomings in terms of process integration and automation. For example, some equipment requires separate steps for loading, inspection, processing, cleaning, and unloading, resulting in low production efficiency; or the lack of a real-time visual inspection system makes it difficult to ensure consistent processing quality.

[0007] Furthermore, the laser generating device is located close to the first visual inspection device, and the turntable is located between the loading bin and the unloading bin.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] Please see Figure 1-4 The camera lens laser texturing equipment in this embodiment includes a machine base 1, a feeding bin 2 fixedly installed on the top of the machine base 1, a first vision inspection device 3 fixedly installed on the top of the machine base 1, a laser generator 4 fixedly installed on the top of the machine base 1, a turntable 5 fixedly installed on the top of the machine base 1, a cleaning station 6 fixedly installed on the top of the turntable 5, a cleaning device 7 fixedly installed on the top of the machine base 1, a robotic arm 8 movably installed on the top of the machine base 1, a light source bracket 9 fixedly installed on the top of the machine base 1, a second vision inspection device 10 fixedly installed on the top of the machine base 1, and a discharging bin 11 fixedly installed on the top of the machine base 1.

[0016] exist Figure 3 In the process, the loading bin 2 is used to store camera lenses to be processed. The design of the loading bin 2 makes it easy for the robot arm 8 to grab the lenses and transfer them to the subsequent processing position. The first vision inspection device 3 is used to perform preliminary visual inspection on the lenses in the loading bin 2 to ensure that the lens quality meets the processing requirements.

[0017] exist Figure 2 In the process, the laser generator 4 generates a high-energy laser beam to perform laser texturing on the surface of the lens mold core. The turntable 5 is the main platform for lens processing. The top of the turntable 5 is equipped with multiple processing positions. Each processing position can fix the lens by vacuum adsorption. The turntable 5 rotates to transfer the lens to different processing positions in sequence.

[0018] exist Figure 4 In the process, the cleaning station 6 is located at the center of the turntable 5 and is used to clean the processed lenses. The cleaning device 7 is close to the cleaning station 6 and removes the residue on the lens surface by means of blowing air. The robotic arm 8 is responsible for transferring the lenses between the stations to realize the automated processing flow. The light source bracket 9 is fixedly installed on the top of the machine 1 to provide lighting. The second vision inspection device 10 is located below the light source bracket 9 and performs the final visual inspection on the processed and cleaned lenses to ensure the processing quality.

[0019] In summary, this camera lens laser texturing equipment places the camera lens to be processed in the loading bin 2, activates the first vision inspection device 3 to perform preliminary inspection on the lens in the loading bin 2, confirming whether the position, orientation, and surface quality of the lens meet the processing requirements. The control system commands the robot arm 8 to move, the robot arm 8 picks up qualified lenses from below the first vision inspection device 3 and transfers them to the designated processing position on the turntable 5. The turntable 5 has multiple processing positions, which can process multiple lenses simultaneously. At the processing position, the lens is positioned by a vacuum adsorption device to ensure the stability and accuracy of the lens during processing. The laser generator 4 is activated, and according to preset processing parameters such as laser power, scanning speed, and pulse frequency, the surface of the lens core is laser texturized. After processing, the robot arm 8 transfers the lens from the processing position to the cleaning station 6 in the middle of the turntable 5. The cleaning station 6, in conjunction with the cleaning device 7, cleans the lens surface by blowing air to remove processing residue. After cleaning, the robot arm 8 transfers the lens to the second vision inspection device 10 for secondary inspection, removing residues and contaminants generated during the process. The second vision inspection device 10 performs a comprehensive inspection of the lens's processing quality, including surface morphology, roughness, and the presence of defects. Lenses that pass the secondary inspection are picked up by the robot arm 8 from below the second vision inspection device 10 and transferred to the unloading bin 11. This solves the problem that laser texturing technology uses a high-energy pulsed laser beam to irradiate the surface of the lens core, forming micron- to submicron-level microstructures such as pits, protrusions, or disordered rough particles. These microstructures effectively reduce the reflectivity of non-optical surfaces by increasing the light scattering path, thereby reducing stray light interference. However, existing laser texturing equipment has shortcomings in terms of process integration and automation. For example, some equipment requires steps to complete the loading, inspection, processing, cleaning, and unloading processes, resulting in low production efficiency; or the lack of a real-time vision inspection system makes it difficult to ensure the consistency of processing quality.
