Through adopting above-mentioned technical scheme, the motor passes through control cabinet control switch, and after the motor was opened, the gear can be removed on the rack, realizes the removal of whole movable beam, and then realizes the removal of laser head, very convenient and fast.

The utility model is further provided with: and an illuminating lamp is arranged below the moving beam towards the direction of the objective table.

By adopting the technical scheme, the illuminating lamp can observe the appearance of the product in real time in the processing process or after the processing is finished, so that dust and particulate matters are reduced to be adhered to the surface of the product to influence the processing.

The utility model is further provided with: the laser head is a dynamic focusing engraving head.

Through adopting above-mentioned technical scheme, dynamic focus sculpture head belongs to prior art, contains Z axle dynamic focus mirror, first focus mirror, second focus mirror, X axle mirror and Y axle mirror that shakes in its casing, can realize four-axis linkage adjustment focus through its three-axis linkage and outside mobile mechanism, increases the processing breadth of product for originally 30 mm's processing breadth enlarges to 120mm 300mm, very big promotion processing breadth.

In summary, the utility model has the following advantages:

1. the laser head is arranged on the portal frame, so that the technical prejudice that the laser head can only be arranged in the frame type machine table is overcome, the focus of the laser head is raised, the focal length is increased, the processing width of a product is further enlarged, and the difficulty of small processing width is solved;

2. the laser head is set to be a dynamic focusing engraving head, and the portal frame is provided with the moving mechanism for driving the laser head to linearly move, so that the laser head can adjust the focus in a four-axis linkage way, and the processing width of a product is increased;

3. through setting up the light, the light can be in the course of working or after finishing processing real-time observe the product appearance, reduces dust, particulate matter adhesion and influences the condition emergence of processing on the product surface.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the large-format laser etching machine comprises an objective table 1 for placing a plate to be processed, and a frame type portal frame 2 is integrally formed at the top of the objective table 1.

The portal frame 2 is provided with a moving mechanism 4, and the moving mechanism 4 comprises a linear guide rail 401 fixed on the top of the portal frame 2 and arranged in parallel, and a moving beam 402 with two ends connected on the guide rail 401 in a sliding manner. The laser head 3 is mounted to the side wall of the moving beam 402, i.e. the laser head 3 is located on top of the gantry 2 and the laser head 3 is directed towards the stage 1.

A rack 403 is fixed to the top of the gantry 2 below the moving beam 402, the rack 403 is parallel to the guide rail 401, and the rack 403 is located inside the guide rail 401. A motor 404 is installed above the moving beam 402, an output shaft of the motor 404 vertically passes through the moving beam 402, a gear (not identified in the figure) meshed with the rack 403 is coaxially fixed at the penetrating end, and after the motor 404 is started, the moving mechanism 4 drives the laser head 3 to move along the direction of the guide rail 401.
