A laser marking device

Abstract

The embodiment of invention discloses laser marking equipment. The laser marking equipment comprises a laser source, a light path adjusting module and multiple light beam adjusting devices. The lasersource is used for generating laser beams. The multiple light beam adjusting devices are used for adjusting the laser beams to different line widths. The light path adjusting module is used for determining the pre-marking laser line width according to a marking drawing and adjusting the transmission direction of the laser beams generated by the laser source according to the pre-marking laser linewidth, so that the laser beams are emitted into the corresponding light beam adjusting devices. By arranging the multiple light beam adjusting devices, the light path adjusting module is utilized forcontrolling the spreading direction of the laser beams generated from the laser source, the laser beams can be emitted into different light beam adjusting devices according to needs, the line widths of the laser beams are adjusted through the light beam adjusting devices, and the marking work of different line widths is completed through one laser source.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of laser coding, and in particular, to a laser coding device. Background technique [0002] In the process of preparing the naked-eye 3D flat panel, it is usually necessary to grow a layer of indium tin oxide (Indium Tin Oxides, ITO) material on the substrate of the 3D flat panel, and form a sealing frame on the side of the ITO material away from the substrate. Since the sealing frame will bring in a certain amount of water vapor during the formation process, when the 3D flat panel display works, the current flowing in the ITO material will electrochemically react with the water vapor in the sealing frame, thereby corroding the 3D flat panel. In order to prevent the corrosion of the 3D plate due to electrochemical reaction, it is necessary to peel off the ITO material corresponding to the position of the sealing frame. [0003] In the prior art, laser coding is often used to peel off t...

Problems solved by technology

However, since the same 3D plate often includes a variety of sealing frames with different widths, multiple lasers are required to generate laser beams with different line widths when coding, and a laser beam with a line width is used to complete the corresponding one on the 3D plate. Therefore, it is necessary to use multiple lasers to code multiple times to complete the stripping of the ITO material on the entire 3D flat panel. The coding process is cumbersome, the coding efficiency is low, and error-prone
