Peripheral coding positioning system

Abstract

The embodiment of the invention discloses a peripheral coding positioning system which comprises a coding bar and a coding recognition device, wherein the coding device is arranged in the peripheral direction of a tank product to be processed, the coding bar comprises a coding recognition baseband and a plurality of coding lines arranged on the coding recognition baseband, the plurality of coding lines are sequentially and vertically arranged in the length direction of the coding recognition baseband, and the coding recognition device is used for recognizing the coding lines and positioning processing parts of the tank product. By adopting the invention, because coding occupies a smaller position, the appearance attractiveness of the product is not influenced; a position value can be directly read out by adopting binary coding, rotations in left and right directions are carried for realizing positioning in the shortest time and distance; redundancy exists in the coding, whole positioning is not influenced by partial coding failures or errors; and the peripheral coding positioning system can also be applied to peripheral positioning of various packages or printing materials, and has wide application range.

Description

technical field [0001] The invention relates to a positioning system, in particular to a circumference coding positioning system. Background technique [0002] In recent years, the demand for special-shaped tanks in the international and domestic markets is limited to symmetrical structures, or asymmetrical structures that are relatively independent of printed patterns. With the improvement of technology and market demand, customers have more and more requirements for tank shapes. Diversification, the customer requires that the shape of the can can change with the printing pattern, and the visual effect is better. Due to the difficulty of technology and technology, it has an anti-counterfeiting effect to a certain extent. It is necessary to realize the tank body on the basis of the existing technology. The corresponding change of the printing pattern, because the printing and deformation processing are not processed at the same time, and the cans are all cylinders before for...

Problems solved by technology

[0003] In the prior art, the method of positioning and processing such cylinder patterns is mostly adopted in the way of cylinder rotation + color mark detection, that is, it is composed of a color mark sensor and a rotating cylinder device. In the process of printing, as a mark of the printing position, when positioning, first rotate the cylinder, and stop the rotation when the color mark is detected, so that the printing patterns of the cylindrical objects to be processed can be uniformly positioned to a specific position, but there are certain defects in this method, because of the irregularity of the object to be processed, the rotation angle may range from 0 to 360 degrees. In the current high-speed processing, time consumption is also crucial, so This method has significant limitations
