Abstract

The present invention discloses a Longmen n. broad width three-dimensional solid body laser inner carving apparatus with high speed which includes a machine body, a laser cooling device is set in the machine body bracket, an operation table-board is set on the machine body bracket, two Y axis moving support tramroads and a Y axis drive transmission device are set on two sides of the machine body bracket of the operation table-board, a X axis moving support tramroad and a X axis drive transmission device, which can move along the Y axis moving support tramroad, are connected between two Y axis moving support tramroads, a moving platform is connected with the X axis moving support tramroad, two Y axis moving support tramroads are equipped with transmission devices respectively, an input end of the transmission device connects with a servo-motor with synchronous operation, the moving platform connects with a Z axis moving tramroad and a Z axis moving drive transmission device, the moving platform also is equipped with a laser and a light route. The Longmen broad width three-dimensional solid body laser inner carving apparatus with high speed has compact and simple structure for realizing broad width inner carving with high speed, such as 1500*1000 mm, and can be widely used in the glass decoration industry.

Description

technical field [0001] The invention belongs to laser processing equipment, in particular to a three-dimensional laser internal engraving machine. Background technique [0002] The laser engraving machine is a laser processing equipment integrating light, machinery and electricity. It is a high-tech product that combines laser technology and computer technology and uses them reasonably. It can engrave a variety of graphics, images, and texts in crystal and glass, but now with the improvement of people's living standards and the pursuit of individuality, it is more hoped that crystal glass engraving products can be used in large-format portraits. It can be used in photos, home, restaurant and hotel decoration. [0003] However, the laser engraving machines currently on the market can only be used for small-format or quasi-large-format crystal and glass engraving. [0004] The quasi-large-format laser engraving machines generally use a superimposed two-dimensional or three-d...

Problems solved by technology

[0005] Now on the market for laser engraving machines with slightly larger motion strokes, the X and Y motion systems usually use motor-driven toothed synchronous belts and drive shafts. Its disadvantages are that the span of the gantry built cannot be too large, and the transmission accuracy is low. The load is light, and the timing belt is prone to stretching and deformation after long-term operation, which affects the repeat positioning accuracy. In the case of large spans, it is easy to cause out-of-synchronization of the gantry movement, which cannot meet the requirements of the wide-width laser engraving machine. and repeat positioning accuracy requirements for large linear strokes

[0006] However, most of the current general laser engraving machines adopt the arrangement of the laser not moving when the workpiece is not moving, which will cause the laser light path to be too long and require multiple changes in the direction of the light path, so that the accuracy of the light path transmission is easily affected. The change of light direction is easy to cause light energy loss because it needs to add multiple reflectors to complete it.
