In the cell phone manufacturing industry, cell phone keys are small, but they are crucial to the user's operating experience. From answering a call, adjusting the volume to various quick operations, the accuracy and reliability of the keys are crucial. As the competition in the cell phone market becomes more and more intense, consumers' demand for cell phone quality is constantly improving, which makes the testing of cell phone keys an indispensable part of the cell phone production process.

When facing the complex shape and fine size requirements of cell phone keys, traditional testing methods often make it difficult to accurately grasp the quality of the keys, leading to the inflow of defective products into the market and affecting the reputation of the brand. Therefore, seeking for more advanced testing technology is the key to improve the quality of cell phone keys and guarantee the overall quality of cell phones.

Telecentric lens characteristics:

1, low distortion: to ensure that the captured image is a true reproduction of the actual shape and size of the object, which is critical for the accurate detection of the size and shape of the phone button deviation.

2, large depth of field: in a certain range can maintain a clear image, even if the cell phone keys are uneven, can also clearly capture the details of each part.

3, telecentric lens sensitivity to light is more uniform, can effectively avoid image shadows or reflections due to light problems caused by interference, to provide a clear and stable image base for accurate detection.

Solution:

Industrial Lens: POMEAS high-resolution telecentric lens has excellent edge-grabbing ability, which can accurately capture the edge contour of cell phone buttons, making it difficult to hide even the smallest imperfections.

Industrial Camera: With its high pixel count and high frame rate, the HD industrial camera can quickly and clearly capture the image of a cell phone key, providing rich data support for subsequent analysis.

Visual light source: The ring-shaped gap light can evenly illuminate the surface of the cell phone keys, which not only makes the details around the keys clearly visible and effectively avoids the detection blind spot caused by uneven light, but also enhances the contrast between the keys and the background to a certain extent, which facilitates better recognition of the shape and size of the keys.

Results Showcase:

By combining POMEAS high-resolution telecentric lens, high-definition industrial camera, and ring gap light, not only can it perform all-around appearance inspection of cell phone buttons, but also can measure the size of cell phone buttons easily, which greatly improves the inspection efficiency and accuracy.
