AI Technical Summary

Problems solved by technology

[0003] The main defects of the prior art are as follows: 1. Slow scanning speed and low efficiency; 2. The output laser spot is circular, so the edge of the processed image is jagged, and the imaging quality is poor; 3. There are large, High power consumption, complex cooling methods, difficult maintenance and other issues limit the number of laser output channels; 4. High requirements for roller speed, processing accuracy and dynamic and static balance

Embodiment 1

[0021] see image 3 The technical solution adopted by the present invention to solve the above technical problems includes an engraving method for a thermal laser engraving machine, which includes a computer 1, a controller 2, an optical engine 3, a grating encoder 4, a traverse mechanism, The transmission mechanism, the roller 10 and the tailstock mechanism, the transmission mechanism is connected with the roller 10 and the tailstock mechanism, the controller 2 is connected with the optical engine 3, the grating encoder 4, the traverse mechanism, the transmission mechanism, the tailstock mechanism and the computer 1 respectively Connected, the optical engine 3 is connected with the traverse mechanism, and the computer 1 is provided with a control program; the engraving method comprises the following steps:

[0022] The roller 10 is coated with heat-sensitive photoresist,

[0023] baked plate,

[0024] Raw image files are converted to bitmap files,

[0025] The bitmap file ...

Embodiment 2

[0030] In this embodiment, the first three steps are:

[0031] Raw image files are converted to bitmap files,

[0032] Roller coated heat-sensitive photoresist,

[0033] baked version.

[0034] Following steps are with embodiment 1.

Embodiment 3

[0036] In this embodiment, the first three steps are:

[0037] Roller coated heat-sensitive photoresist,

[0038] Raw image files are converted to bitmap files,

[0039] baked version.

[0040] Following steps are with embodiment 1.

[0041] During specific implementation, at first the roller blank 10 through machining is coated with heat-sensitive photoresist and baked, turn on the power, start the computer 1, and the original image forms a bitmap file through the raster image processing in the control program of the computer 1 and sends it to the computer. To the controller 2, the controller 2 converts the bitmap file into a data string that matches the grid light valve drive circuit and sends it to the register of the grid light valve, thereby controlling the optical engine 3 to align the roller with the set image The cylinder blank 10 is processed by laser scanning. At the same time, the controller 2 controls the work of the grating encoder 4, the traverse motor 6, the ...

Description

Technical field: [0001] The invention relates to a heat-sensitive laser engraving machine and its engraving method, in particular to a thermal-sensitive laser engraving machine based on a grid light valve (GLV) and its engraving method, which is mainly suitable for gravure plate making and embossing plate making. Background technique: [0002] The lasers of laser engraving machines in the prior art usually use semiconductor point-shaped laser light sources. Each laser light source needs to be driven separately and needs to be coupled by optical fiber transmission. The structure is complex, and the emitted laser beams are usually only 1, 2, 4 or 8 bundles. The plate-making method in the prior art includes the following steps: coating a roller with ultraviolet photosensitive adhesive; converting an original image file into a bitmap file; controlling a point laser according to the bitmap file; optical fiber transmission and processing; laser scanning processing; development; co...
