I. Background of Mobile Phone Case Dimension Inspection

With the growth of the 3C electronics industry, demand for phone cases has surged, and consumers now demand higher quality. Dimensional accuracy directly impacts compatibility and user experience. Phone case production features diverse categories and small batches. Traditional manual inspection is inefficient and prone to errors, making automated inspection solutions essential. Machine vision and line laser sensors are the mainstream choices.

II. Comparison of Two Mainstream Detection Methods and Their Advantages and Disadvantages

Machine vision solutions capture images using cameras and lighting systems, then extract dimensional features through algorithms for comparison against standards. Suitable for flat phone cases, they achieve 2D inspection accuracy of 0.01-0.05mm, with individual part inspection taking 0.5-2 seconds. Costs range from 30,000 to 100,000 yuan, but the system is sensitive to lighting conditions.

Line laser sensing solutions operate on the principle of triangulation, projecting laser lines to capture 3D coordinates and build models. They excel at inspecting complex curved surfaces with 3D accuracy ranging from 0.001 to 0.01 mm and strong resistance to light interference. However, inspection takes 2-5 seconds, costs between 100,000 and 300,000 yuan, and is sensitive to vibration.

Key differences are pronounced: - Accuracy: Machine vision excels at 2D inspection, while line lasers dominate 3D applications. - Efficiency: Machine vision is more efficient, suited for high-volume production. - Cost and environmental adaptability: Machine vision is lower-cost but environment-dependent; line lasers are higher-cost yet resistant to light interference.
