Screen printing mesh, wire mesh lattice grid

Time-saving quality inspection with the new digital microscope Roboscope. It acquires test images with an area of up to 200x300mm and a resolution of up to 1.8µ, it checks dimensions, deviations in the mesh size and other defects using industrial image processing.

# 2 filter fabric, is the mesh size even?

The user can define recipes with settings for the image recognition, based on these settings the industrial image inspection then sorts the various mesh sizes. Each group is drawn in a different color. In the picture above, meshes that are of the wrong size are colored red.

# 3 Enlargement of the picture above

Detail, the overall picture has a size of 470MB. The blue dimension lines show that the sizes (in mm) differ significantly

# 5 The mesh size in 3,8% of the sample area is incorrect

The openings marked in red by the image recognition deviate from the target value. Also suitable for testing stainless steel wire mesh

# 7 Check the dimensions and areas

Checking the grid dimensions. The pop-up window displays the values calculated by the image recognition for area, length and positions.
