Automatic laser marking device

Abstract

The invention discloses an automatic laser marking device in the field of laser marking. Supporting air cylinders and moving wheels are arranged, so that when the supporting air cylinders are retracted, the supporting air cylinders move far away from the ground and the moving wheels make contact with the ground, the automatic laser marking device can be moved by the moving wheels, and when the automatic laser marking device needs to be fixed, an operator can control the supporting air cylinders to stretch so as to enable the height of a horizontal plane where the bottom ends of the supportingair cylinders are located and a horizontal plane where the bottom ends of the moving wheels are located to be the same, so that the bottom ends of the supporting air cylinders and the bottom ends of the moving wheels can make contact with the ground simultaneously for fixing the automatic laser marking device to prevent the automatic laser marking device from moving; by disposing vacuum sucking systems, circular grooves and vacuum sucking holes, a PCB (printed circuit board) can be fixed onto platform plates through vacuum sucking, and therefore the PCB can be fixed quickly and stably; by arranging the platform plates which are respectively a left vacuum platform plate and a right vacuum platform plate, the automatic laser marking device can perform double-station laser marking, so that the marking efficiency is improved.

Description

technical field [0001] The invention relates to the field of laser marking, in particular to an automatic laser marking device. Background technique [0002] Printed circuit board (PCB circuit board), also known as printed circuit board, is the provider of electrical connections for electronic components. Its development has a history of more than 100 years, and its design is mainly layout design; the main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, and improves the automation level and production labor rate. According to the number of layers of circuit boards, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards. Since the printed circuit board is not a general terminal product, the definition of the name is slightly confusing. They are not the same, so when evaluating the industry, the two are related but cannot be said to be the same. Anothe...
