Description
Technical Field
The invention relates to an automatic intelligent sampling system for cold-rolled strip steel, and belongs to the technical field of cold-rolled production equipment.
Background
The quality control of the cold-rolled strip steel product is obtained by manual sampling and detection, namely, in the production process of a steel coil, a section of strip steel sample is manually cut and sent to an inspection center for carrying out related item detection on mechanical property, coating weight and the like. The current sampling mode is to manually operate shearing equipment, shear a section of strip steel and transport the strip steel to an inspection and testing center by using tools such as a forklift. Checking the transmitted sample plate by the staff of the checking and testing center, stamping the sample plate into a standard sample for detecting the tensile size of the mechanical property or the weight of the coating by using special equipment after marking, then carrying out detection tests on the mechanical property or the weight, the adhesion and the like of the zinc layer, and finally uploading the detection result to the system.
The existing cold-rolled strip steel sampling detection method has the following inconveniences: the traditional sampling device needs to be designed with a complicated sample plate and waste material separation (such as a magnetic sorting mechanism) device, a sample collection lifting platform and other mechanisms, and the mechanism occupies a large space and has high equipment failure rate. The manual sampling consumes a large amount of manpower, on one hand, a cold rolling or galvanizing unit needs to manually carry samples and mark the samples (by a label pasting mode) and use a forklift and other tools to convey the samples to an inspection center, on the other hand, the inspection center needs a large amount of personnel to receive and count the samples, then the samples are punched and processed by a milling machine, the samples are marked by a handwriting mode, and then various types of detection are carried out. Because the steps of strip steel sampling, sample feeding, counting, processing, marking and the like are all operated manually, errors are easy to occur. Due to manual sampling, the position information of the sample plate in the whole volume cannot be accurately identified, and accurate information cannot be provided for subsequent big data analysis. According to different standards, the position requirements or sampling direction requirements of samples to be processed are not uniform, and manual operation is easy to cause disorder. The area of the manually sampled plate is large and greatly exceeds the area required by an actual inspection sample, so that material waste is caused; because the sample plate of the cold-rolled steel coil needs to be reserved for a period of time for rechecking, a large number of sample plates can be reserved and accumulated on site, and a large amount of space is occupied.
