Tire mold laser cleaning light path

Abstract

The invention provides a tire mold laser cleaning light path. The tire mold laser cleaning light path comprises a scanning galvanometer, a plano-convex lens I, a motor, a plano-convex lens II, a biconvex lens, a first 45-degree plane mirror, a second 45-degree plane mirror, a protective lens, a gas protection device, a motor and a galvanometer window mirror. A light beam goes into the scanning galvanometer, then passes through the galvanometer window mirror and is transmitted to the first plano-convex lens. The convex surface faces upwards to gather the light beam to the focal point, and thenthe light beam is continuously transmitted and diffused to the second plano-convex lens. The convex surface faces downwards to turn the light beam into parallel light again. Different sizes of light spots, adjustable focal lengths and gas shield are provided and output from the interior of the light path and the length of the light path is extended to adapt to laser cleaning of different sizes oftire molds. The tire mold laser cleaning light path can realize different scanning tracks and focal lengths and can conduct full-automatic cleaning on the tire molds to achieve automation and improvethe efficiency.

Description

technical field [0001] The invention belongs to the technical field of laser cleaning, in particular to a tire mold laser cleaning optical path. Background technique [0002] Cleaning of tire molds: Tire manufacturers all over the world manufacture hundreds of millions of tires every year. Cleaning of tire molds must be fast and reliable during the production process to save downtime. Traditional cleaning methods include sand blasting, ultrasonic or carbon dioxide cleaning, etc., but these methods usually have to cool the high-heat mold for several hours before moving it to the cleaning equipment for cleaning, which takes a long time to clean and easily damages the precision of the mold , chemical solvents and noise will also produce safety and environmental issues. Using the laser cleaning method, because the laser can be transmitted by optical fiber, it is very flexible in use; because the laser cleaning method can be connected by optical fiber to guide the light to the d...
