Description

Technical Field

[0001] The utility model relates to the technical field of fabric color difference detection, and specifically to a fabric color difference detection device. Background Art

[0002] Currently, most factories use color chart comparison and manual visual inspection to detect fabric color differences. This method is susceptible to multiple factors, such as vision, lighting, and fatigue, resulting in poor color difference detection accuracy. To improve color difference detection accuracy, fabric color difference detection devices have been developed. These use industrial cameras to capture fabric images, which are then analyzed by a backend system to determine whether they meet standards.

[0003] A Chinese patent discloses a fabric color difference detection device with publication number CN217605125U. The technical solution disclosed in the patent document is as follows: it includes a main frame, which is symmetrically provided with two groups of main frames. A cloth guiding mechanism is installed between the two groups of main frames, and side mounting plates are vertically fixed above the two groups of main frames. A linear guide rail is provided on the inner side of the side mounting plate along the height direction. The linear guide rail has a matching slider, and the slider is connected to an anti-rollover mechanism.
