Tire laser marking device and method based on machine vision identity

Abstract

The invention discloses a tire laser marking device and a method based on a machine vision identity. The device comprises a production line conveyor belt, a clamping and rotating device, an information collection working region, a tire data reader, a mark position reader, an auxiliary lighting device, a smog extracting facility, a laser marking working region, smog filtering and air discharge equipment, a radio frequency CO2 laser, a focusing work bench, a high speed laser scanner, a scanning focus lens, a collimating and beam expanding system, a reflector and a computer system. The information required to be marked is etched on the surface of the tire through the machine vision identity technology and the laser beam high speed scanning and marking technology by utilizing the radio frequency CO2 laser. The invention has the beneficial effects that: through the machine vision identity technology, the marking position is automatically judged according to the different shapes and the arrayed positions of the tires on the production line and an optical beam scanner is guided to be positioned accurately without a special machinery and a manual marking locating device, then a seamless transition with the production line of the tires is achieved and the work efficiency of equipment is further improved.

Description

technical field [0001] The invention relates to a tire laser marking device and method based on machine vision recognition, in particular to a high-performance laser scanning tire marking device and method based on machine vision image recognition, belonging to the technical field of laser processing. Background technique [0002] In recent years, in the international automobile manufacturing industry, especially in the production process of automobile tires, European and American countries require the establishment of special quality traceability systems for automobile tire products with industry regulations, mandatory quality standard systems and even government laws. For example, the U.S. Federal Department of Transportation and Transportation, the Highway Administration, and the Automobile Industry Legislative Working Group stipulate that all tire manufacturers must establish an "identity card" system for tires, which must have traceability and traceability, so that once ...
