Laser engraving device and engraving method for curved glass

Abstract

A laser engraving device for curved glass provided by the present invention includes an operating table top, upright columns are fixed on both sides of the upper end of the operating table, an x-axis driving mechanism is connected between the two upright columns, and the output of the x-axis driving mechanism end is connected with a y-axis drive mechanism, the output end of the y-axis drive mechanism is connected with a z-axis drive mechanism, the output end of the z-axis drive mechanism is connected with a laser head and a displacement sensor, and n Electromagnets are distributed at intervals, n is an integer greater than or equal to 5, a permanent magnet with the same pole as the upper end of the electromagnet is placed on the operating table, and the permanent magnet is located directly below the displacement sensor. The laser engraving device for curved glass and the engraving method thereof provided by the present invention can realize automatic engraving of curved glass with high processing efficiency.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a laser engraving device for curved glass and an engraving method thereof. Background technique [0002] With the continuous development of the construction industry, ordinary flat glass cannot meet the market demand, so curved glass appears. Curved glass also needs to be engraved, cut, polished, polished, cleaned, and dried. Because the structure of curved glass is quite different from that of flat glass, ordinary flat glass processing equipment cannot process curved glass, and special equipment is required. like Figure 4 For the curved glass 11 shown, for the engraving process of curved glass, 11, it is generally necessary to strictly control the distance between the laser head and the engraved surface, so that the arc-shaped grooves carved out can meet the requirements. Before engraving, it is necessary to model in advance according to the shape of the curved glass ...

[0002] With the continuous development of the construction industry, ordinary flat glass cannot meet the market demand, so curved glass has appeared

Curved glass also needs to be engraved, cut, polished, polished, cleaned, and dried. Because the structure of curved glass is quite different from that of flat glass, ordinary flat glass processing equipment cannot process curved glass, and special equipment is required.

like Figure 4 For the curved glass 11 shown, for the engraving process of curved glass, 11, it is generally necessary to strictly control the distance between the laser head and the engraved surface, so that the arc-shaped grooves carved out can meet the requirements. Before engraving, it is necessary to model in advance according to the shape of the curved glass 11 and set parameters such as the movement trajectory of the engraving machine. The operation is cumbersome and the processing efficiency is low.
