HANSWELL 3D+AI visual technology assists in the manufacturing of automotive parts and empowers flexible production lines

In the process of automobile manufacturing, the safety and matching degree of automotive components play a crucial role. Improper component combinations may lead to safety issues such as power loss, increased vibration, and increased noise. The manual quality inspection method is not only inefficient, but also easily influenced by personal abilities, leading to missed or false inspections, which cannot meet the modern manufacturing industry's demand for efficiency, accuracy, and reliability.

Therefore,under the trend of intelligent and lightweight development, the demand for machine vision in the automotive industry is expected to continue to increase.

The main role of machine vision technology

Dimensional measurement

When using traditional manual measurement methods, it is often difficult to accurately distinguish the subtle differences between components due to human factors. However, with the introduction of machine vision inspection systems, precise measurement of component dimensions and features can be achieved, which not only significantly improves measurement accuracy but also greatly enhances overall production efficiency.

defect detection

By equipped with high-performance cameras and optimized image processing algorithms, the visual inspection system can capture and recognize product images in a short period of time, accurately detecting surface problems such as defects, scratches, and dents, as well as unqualified internal assembly.

Guiding positioning

By using visual inspection technology, it is possible to automatically identify the position, size, shape, and type of materials, perform precise positioning and matching, achieve automated grasping and handling processes, significantly reduce manual intervention, and ensure the safety and efficiency of the production process.

Component identification and tracking

By installing cameras and sensors on the production line, the position and status of components can be tracked, ensuring assembly according to plan, which helps reduce assembly errors and downtime on the production line.

With the complexity of the manufacturing process for new energy vehicles, there is a significant increase in the required precision components, which puts higher demands on the efficiency and accuracy of testing.
