The invention discloses a code spraying system and method for a large cylindrical workpiece. The system comprises a base, two supporting and weighing mechanisms which are used for supporting the two ends of the cylindrical workpiece and weighing the weight of the cylindrical workpiece, can move relative to the axial direction of the cylindrical workpiece to adjust the distance, and can drive the circumferential rotation of the cylindrical workpiece, and a code spraying mechanism erected between the two supporting and weighing mechanisms. The code spraying mechanism can axially move relative to the cylindrical workpiece, is provided with a code spraying head and can ascend, descend and rotate. A code spraying device is provided with an axial detection encoder, an end face detection mechanism and a circumference mark detection mechanism. The system is provided with a control device which is used for controlling the circumferential rotation speed of the supporting and weighing mechanisms, the axial movement speed of the code spraying device, ascending and descending of the code spraying head and switching of the code spraying direction, and the axial ink spraying speed and the circumferential ink spraying speed are respectively controlled according to the axial movement speed of the code spraying mechanism and the circumferential rotation speed of the supporting and weighing mechanisms. The code spraying system has the advantages of good flexibility, strong expansibility and the like.
Description
technical field [0001] The invention belongs to the field of coding of large workpieces, in particular to a coding system and method for large cylindrical workpieces. Background technique [0002] With the popularization of Made in China 2025 in various domestic industries, there are more and more demands for automatic assembly of large cylindrical workpieces such as oil pipes, steel pipes, and ammunition; in the automatic welding and assembly industry of large cylindrical workpieces, it is necessary Automatic coding, including axial coding and radial coding. At the same time, the coding content is required to include numbers, letters, text, symbols and simple graphics. The color of the coding includes black and white. After the coding is completed, it needs to be dried deal with. However, due to the characteristics of large size and heavy weight of large cylindrical workpieces, manual silk screen printing currently has problems such as high labor intensity, poor consistenc...
