Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel strip processing, in particular to an intelligent detection and marking device for surface defects of a stainless steel strip. Background Art

[0002] After heat treatment, stainless steel strips produce some surface quality defects. During use, after the stainless steel strips are unrolled, they need to be inspected by a special inspector to prevent defective products from flowing into the subsequent production line. Manual inspection is inefficient and easy to miss, causing defective products to flow into the production line. At the same time, because there is no obvious marking, a situation is easy to occur: when producing product A, a roll of steel strip is put on, and after opening it, it is found that there is a quality defect that affects product A, but this defect does not affect product B and can be used for the production of product B. At this time, the steel coil needs to be replaced.

[0003] We have designed a stainless steel strip that is heat treated in an annealing furnace, and then uses an intelligent surface defect detection and marking device to complete the surface quality defect marking, and then reel it. When the stainless steel strip is unrolled and used, the defect position is skipped according to the mark and used directly, which improves production efficiency and avoids defective products from entering the production line. At the same time, according to the statistical frequency of different surface quality defects, data support is provided for the improvement of surface quality defects. In subsequent use, according to the impact of different defects, the use of steel coils can be reasonably arranged to improve material utilization. Utility Model Content

[0004] The main purpose of the utility model is to provide an intelligent detection and marking device for surface defects of a stainless steel strip, so as to effectively solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an intelligent detection and marking device for surface defects of stainless steel strips, comprising a servo motor, a control console, a steel strip winder, a coder bracket, an intelligent coder, and a collection camera; the coder bracket is a door-type structure, and its crossbeam is composed of a screw track. The intelligent coder is arranged on the screw track, and a servo motor and a control console are fixed on one side of the door-type bracket of the coder bracket, and the servo motor is connected and fixed to the screw track. A steel strip winder is arranged on the rear side of the crossbeam of the coder bracket, and a collection camera is arranged on the front side of the crossbeam of the coder bracket. When winding, the steel strip is tensioned and passes under the collection camera and the crossbeam of the coder bracket in turn. A control system and a control computer are arranged in the control console, and a surface defect picture library is stored in the control computer.

[0006] Preferably, the acquisition camera is located above the steel strip, and can acquire surface defects of the stainless steel strip when the steel strip passes from below, and transmit the defect position coordinates and defect pictures to the control computer of the console. The control computer identifies the defect type by comparing the acquired pictures with the defect picture library; then the control computer transmits the defect position coordinates and defect type to the intelligent inkjet printer.

[0007] Preferably, the control system in the console can send instructions to the servo motor according to the defect position of the steel strip. The servo motor directs the intelligent inkjet printer to run horizontally on the screw track of the inkjet printer bracket to the horizontal coordinate where the defect is located. When the steel strip passes through, according to the instructions issued by the control computer, the intelligent inkjet printer sprays different marks on the defect position of the steel strip according to the defect type.

[0008] Beneficial effects of the utility model: Compared with the manual naked eye detection of steel strip defects, the utility model has the advantages of high efficiency and accurate classification, which prevents defective products from flowing into the production line. At the same time, according to the statistical frequency of different surface quality defects, data support is provided for the improvement of surface quality defects. In subsequent use, according to the impact of different defects, the use of steel coils can be reasonably arranged to improve material utilization. BRIEF DESCRIPTION OF THE DRAWINGS
