Tension-free wind-up roller and CCD visual inspection equipment

The utility model relates to the technical field of CCD (Charge Coupled Device) detection, in particular to a tension-free wind-up roll and CCD visual inspection equipment provided with the tension-free wind-up roll, which comprises a roll body, a plurality of bearings and a plurality of abutting rings, the roll body is used for being externally connected with a driving source and is driven by the driving source to rotate, the plurality of bearings are sleeved on the outer side of the roll body side by side, and the abutting rings are arranged on the bearings. The outer sides of the bearings are sleeved with the abutting rings side by side, a plurality of concave holes are formed in the outer surfaces of the abutting rings, and balls used for abutting against the film material/cloth are arranged in the concave holes. According to the utility model, the roller body drives the abutting ring to rotate, so that a material roll for rolling a film material/cloth by the ball drives the film material/cloth to rotate
