Laser paint-removing system and method

Abstract

The invention provides a laser paint-removing system and method. The system comprises a control device, a laser marking machine, a detecting device and a cleaning device, wherein the control device is internally provided with laser marking software which sets the shape of paint to be removed and the position of removing the paint; the laser marking machine is connected with the control device and used for carrying out laser burning according to the set of the laser marking software; the detecting device is connected with the laser marking machine and is clung to the stream line and used for detecting the motion position of a product to be subjected to paint removal and controlling the laser marking machine to send laser; and the cleaning device is positioned at the downstream station of the laser marking machine and used for cleaning the incompletely dropping paint part. The laser paint-removing method comprises the steps of: 1, determining the shape of the paint to be removed and the position of removing the paint; 2, regulating the laser swinging speed; 3, detecting the position of a product; and 4, cleaning the paint removing surface. The invention has the advantages of achieving the paint-removing function by adopting a non-contact laser burning manner without damaging the internal material of the product, and being simple in operation.

Description

【Technical field】 [0001] The invention relates to the application field of laser paint removal. 【Background technique】 [0002] At present, three methods are generally used to remove the product surface paint: the first is to use mechanical friction to remove the product surface paint, such as using a grinder to scrape off the product surface paint. This method depends entirely on the experience of the operator and manually controls the shape of the removed paint. The position and the depth of paint removal, so this method of removing the paint on the surface of the product does not achieve high accuracy; the second method is to use a solvent to remove the paint on the surface of the product, this method only removes the paint on the surface of the product without damaging the internal materials of the product , but the position and shape of the paint removal on the product surface are not easy to control; the third method is to use a laser machine and its supporting workben...
