Description

Technical Field

[0001] The utility model relates to the technical field of parts detection, in particular to a multifunctional parts appearance detection device. Background Art

[0002] At present, in the industrial field, many parts with studs or T-buckles will have various defects in the manufacturing process. For example, parts with studs may have inconsistent stud inner diameters, defects in the screw threads in the screw holes, foreign matter in the holes, and other problems. Parts with T-buckles may have problems such as T-buckle groove offset and poor groove depth. If defective parts are not eliminated, problems are likely to occur in the subsequent production process, resulting in reduced production efficiency and product quality.

[0003] Existing part defect detection usually uses visual methods for inspection. Manual visual inspection will result in a certain amount of missed detection, and it consumes a lot of time and manpower, greatly increasing production costs. In addition, when performing T-buckle inspection, it is difficult to determine whether the T-buckle groove is offset by visual inspection alone, which easily affects the production efficiency and product quality of the product. In addition, existing part appearance defect detection devices usually use flat cameras for inspection or 3D cameras for inspection. When the same part needs to be inspected in two dimensions and three dimensions, two inspection processes are required, which greatly reduces the inspection efficiency and is not conducive to the development of the enterprise.
