Laser engraving device and engraving method of curved glass

Abstract

The invention provides a laser engraving device of curved glass. The device comprises an operation table board, stand columns are fixed on the two sides of the upper end of the operation table board,an x-axis driving mechanism is connected between the two stand columns, an output end of the x-axis driving mechanism is connected with a y-axis driving mechanism, an output end of the y-axis drivingmechanism is connected with a z-axis driving mechanism, an output end of the z-axis driving mechanism is connected with a laser head and a displacement sensor, n electromagnets are distributed in theoperation table board at intervals, n is an integer larger than or equal to 5, permanent magnets which are the same as magnetic poles at the upper ends of the electromagnets are arranged on the operation table board, and the permanent magnets are positioned under the displacement sensor. The laser engraving device and the engraving method of the curved glass have the advantages that curved glass can be automatically engraved, and the machining efficiency is high.

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. Such as 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 gla...

[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.
