Detection background:

With the rapid development of technology, the 3C industry, or consumer electronics industry, has become one of the most dynamic and innovative sectors in the world. This industry covers a series of high-tech products such as computers, tablet devices, smartphones, smart wearable devices and so on. These products not only require high performance and reliability, but also pursue personalized needs such as thinness, lightness and shapelessness. Therefore, in the manufacturing process, the requirements for the accuracy of parts, assembly quality and finished product inspection are also increasing.

The traditional manual inspection method has been difficult to meet the demand for high-precision and high-efficiency inspection. Machine vision technology has gradually been widely used in 3C industry by virtue of its advantages of high precision, high speed, high adaptability and high reliability. As one of the core components of machine vision system, the performance of industrial lens directly determines the accuracy and efficiency of the inspection system.

3C industry use cases:

1. Cell phone camera inspection:

In the process of cell phone manufacturing, the camera as a key component, the quality of which directly affects the photographic effect of the phone and user experience. Industrial lenses combined with machine vision technology can carry out omni-directional and high-precision inspection of cell phone cameras. For example, by moving two cameras at the same time in a dual-station, the front and rear cameras of the finished cell phone are photographed and detected respectively, and defects such as white dots, black dots, white hairs, and dirt in the camera module can be accurately identified. In addition, AI-based deep learning algorithms can further improve the accuracy and stability of the inspection to ensure that the quality of the camera meets the standards.

2. PCB circuit board inspection:

In electronic products such as Bluetooth headsets, PCB circuit boards are one of the core components. Its mounting and welding quality directly affects the performance and reliability of the product. Industrial lenses combined with AOI (Automatic Optical Inspection) technology can carry out efficient and fast inspection of PCB circuit boards. Through the multi-million focusing lens and high-resolution camera, combined with the MetX multi-sensing measurement system 2D + 3D inspection algorithm, can accurately identify the size and quality of the solder joints and whether there are defects such as burns. This inspection method not only improves the inspection efficiency, but also reduces the error rate of manual inspection.

3. Micro-speaker diaphragm detection:

The diaphragm plays a vital role in the micro-speaker's sound performance. Its positioning accuracy directly affects the sound quality and power of the speaker. Industrial lenses combined with standard vision inspection algorithms and customized combination of lenses and light sources can perform fast and accurate positioning inspection of the diaphragm. Through template matching and circle finding tools, precise identification of the position of the diaphragm can be realized to ensure its accurate position in the assembly process. This kind of inspection not only improves the production efficiency, but also ensures the sound quality and reliability of the product.

4. Periscope camera inspection:

With the continuous improvement of smartphone's photo function, periscope camera has gradually become the standard for high-end cell phones. However, the periscope camera has a complex structure, which requires high assembly precision and inspection. Industrial lenses combined with solutions such as high-precision measuring equipment (MetX Multi-sensor Measurement System) and Focus X laser autofocus microscope system can perform all-round, high-precision inspection of periscope cameras. By simulating the center point movement trajectory of the ceramic ball and measuring key parameters such as magnet-to-coil spacing, it is possible to ensure that the camera meets the standards for accuracy and quality during assembly.

5. Component assembly inspection:

In the manufacturing process of 3C products, the assembly quality of parts directly affects the overall performance and reliability of the product. [...]  [...]  [...]
