Description

Technical Field

[0001] This utility model belongs to the field of visual inspection technology, and in particular relates to a visual inspection device with an adjustable detection range. Background Technology

[0002] The vision inspection module with a prism is installed in the vision inspection equipment. The image of the product to be inspected is presented in the camera through the reflection of the prism, which can play a good role in detecting certain appearance defects of the product.

[0003] Currently, conventional prism-mounted vision inspection systems typically use a dual-axis linear motion system on a vertical plane to move a prism and camera fixed to its moving end, enabling the inspection of different products or different positions on products. However, in some production workshops, certain products require inspection at specific angles. Conventional vision inspection equipment with fixed prism and camera orientations is clearly insufficient for inspecting such products. Manufacturing new inspection devices would increase costs and waste space. Therefore, a new solution is needed to improve or solve these problems. Utility Model Content
