Method for removing burrs of plastic parts through laser

Abstract

The invention relates to burr removing through a laser and provides a method for removing burrs of plastic parts through a laser. The burrs on the surface of the plastic parts are removed through coordination of a laser system and a CCD positioning system, after debugging and correction are conducted, the outlines of the plastic parts are sectioned in sequence through a simple figure, the compensation values between the plastic parts subjected to burr removing through the laser and clean plastic parts are determined, and the burrs of the plastic parts in batches are removed by the laser system according to the compensation values. According to the method for removing the burrs of the plastic parts through the laser, the plastic parts are sectioned through the simple figure, the compensation value of burr removing through the laser system in each section is determined, burr removing of the plastic parts in large batches can be conducted through coordination of the laser system and the CCD positioning system, the tolerance requirement of the plastic parts obtained after the burrs are removed can be met, labor is reduced, cost is reduced, burr removing can be conducted on the plastic parts in large batches, and the efficiency and quality of burr removing are very high.

Description

technical field [0001] The invention relates to laser processing, in particular to a method for removing burrs from plastic parts by using UV laser. Background technique [0002] During the plastic molding process, due to the molding process, mold and product design, raw materials and machines, etc., a layer of flash will be formed on the parting surface of the plastic part. Generally, these flashes are very thin and small, and the size range is generally 0.05~ About 0.2mm, this is the so-called burr. [0003] As customers have higher and higher requirements for product accuracy, shape tolerance and yield rate, it is difficult to meet customer requirements by using traditional manual deburring methods. The traditional method mainly cuts off the burr on the edge of the plastic part manually with a knife, but this method is difficult to ensure that the burr is within the tolerance range after removal, and there are cases where the plastic part body is damaged. In addition, b...
