Wintop Optics: Embracing Innovation with AA Gluing Technology

In the packaging process of the camera lens module, it is usually necessary to go through multiple assemblies. However the accumulation of errors in each assembly can lead to more and more product problems. Traditional threaded combination lenses cannot adjust for these errors, and the final result may cause the captured image to deviate from the center of the picture, resulting in differences in clarity in different areas.

1. Introduction to AA Gluing / AA Bonding Technology

AA process (Active Alignment) is a high-precision technology for camera lens module assembly. It adjusts the Lens alignment to 6 freedom degrees through Tip-Tilt Head, and adjusts the Lens position in 6 directions according to the chart to obtain high-precision optical axis alignment. This technology is mainly used to determine the relative position of each component during the assembly process to ensure the clearest center of the camera picture and improve the uniformity of the resolution of the corners of the image, so as to improve product consistency.

In the realm of automotive imaging, precision is paramount. Wintop Optics, a leading innovator in the field, has embraced Active Alignment (AA) bonding technology to redefine the standards of optical precision. AA technology, at its core, is an advanced optical bonding process that ensures lenses are aligned with micron-level accuracy.

2.The Role of AA Gluing / Bonding in Vehicle Imaging Systems

The automotive industry is rapidly evolving with the advent of autonomous driving and Advanced Driver Assistance Systems(ADAS).

A. High-precision imaging: Autonomous driving and ADAS systems rely on accurate image data to make quick decisions. AA gluing lens technology meets the high-precision imaging needs of autonomous driving by precisely aligning lens elements to ensure image clarity and accuracy.

B. Dynamic environment adaptability: Vehicles encounter various dynamic changing environments during driving. AA gluing lens technology can ensure that the lens maintains stability under high-speed movement and vibration conditions, thus providing continuous and reliable image data.

C. Reliability and durability: ADAS systems need to work stably in a variety of climates and environmental conditions. Because of its high reliability and durability, AA glue structures lens can ensure long-term stable operation of imaging systems and reduce maintenance costs.

D. Fast response time: For autonomous driving systems, fast response is essential. AA gluing lens technology enables fast image capture and processing, helping the system respond in a timely manner.

Wintop Optics' AA gluing lenses technology meets the high demands of this industry by providing lenses that are not only precise but also adaptable to various environmental conditions and capable of seamless integration with other sensors.

5. Manufacturing Process

The manufacturing process of AA bonding involves meticulous preparation of optical elements, precise alignment, bonding, and curing.

1) Cleaning: Cleaning the surface of the lens and front case to increase the adhesion of the glue.

2) Point UV glue: Through the camera and electronic balance, monitor the width, height, weight of the glue, and whether there are problems such as glue breakage.

3) Active alignment: tilt and level alignment through a 6-axis motion platform with a target map.

4) UV pre-curing: ensure the consistency of UV capabilities around.

5) High temperature baking and curing: After UV curing, the product needs to be cured again by high temperature baking.

6.Success Case Studies

AA gluing lens technology not only meets the high-precision and high-reliability requirements of autonomous driving and ADAS for on-board imaging technology, but also plays a key role in improving vehicle safety, adapting to changing environments, and integrating with other sensors. With the continuous advancement of technology, AA gluing technology is expected to play a more important role in the future autonomous driving field.
