Problems solved by technology
[0003] The appearance inspection of traditional compressors adopts manual inspection methods. There is no uniform standard for manual inspection. Missed inspections and false inspections are high, and the efficiency is low and cannot meet the efficiency requirements of mass production in factories.
On the other hand, the wages of workers are high, which increases the cost of compressor production

The invention designs a compressor appearance detection method by using a machine vision technology. The method comprises the steps of firstly, detecting the defects of a compressor nameplate based ona machine vision method and recording a two-dimensional code number, and then preprocessing an image, and carrying out defect detection on seven items including a screw, an air suction pipe, an exhaust pipe, a footing rubber plug, a positioning pin, a liquid storage device, a compressor cylinder body and the like after image preprocessing. The compressor appearance detection method based on machine vision provided by the present invention replaces a traditional manual detection method, the detection tasks can be better met, the accuracy and efficiency of the compressor product appearance detection are improved, and the false detection rate and omission ratio are reduced; and meanwhile, the labor cost is reduced so as to reduce the production cost for the enterprises, the method has very high application value and high economic benefit, and the actual verification proves that the method can be better applied to the actual compressor product appearance detection tasks.
Description
technical field [0001] The invention relates to the technical field of product appearance inspection, in particular to machine vision-based appearance inspection of compressor products. Background technique [0002] The appearance quality of compressor products affects the product recall rate and the reputation of compressor manufacturers, and directly determines the survival of enterprises. With the improvement of the automation level of compressor manufacturing enterprises and the increase of product output, the requirements for the accuracy and efficiency of product appearance inspection of compressors are also increasing. There are many appearance inspection items for compressor products, mainly including the verticality inspection of the suction and exhaust pipes and screw rods, the parallelism inspection between the liquid receiver and the compressor body, the inspection of the cooperation of TP bolts, the inspection of the cooperation of grounding rubber plugs, and th...
