Problems solved by technology

Placed on the laser engraving workbench, it cannot be engraved smoothly, resulting in uneven engraving depth and incomplete patterns
In particular, since the optical fiber needs to be etched on the surface to leak light from the side of the fiber and achieve the effect of emitting light from the side of the fiber, uneven engraving has a great impact on the luminous efficiency of the optical fiber
[0004] The existing laser engraving machine has a hole on the working bearing plate, and the negative pressure chamber and suction pipe are set under the bearing plate to inhale the position of the bearing plate. However, this type of laser engraving machine has requirements for the size of the fabric. , when the fabric area is smaller than the hole area of ​​the laser engraving machine's working bearing plate, it is difficult to realize the suction function, and it is impossible to ensure the flatness of the fiber optic fabric

Embodiment 1

[0046] Such as Figure 1-5 As shown, the laser engraving workbench of the optical fiber fabric includes a worktable 1, and the suction holes 2 covering the entire worktable are evenly arranged on the worktable. The size of the suction holes is 3.0mm-4.0mm in outer diameter and 2.0mm-3.0 mm. A number of connecting pipes 3 are arranged under the worktable, and each suction hole 2 is connected to a connecting pipe 3 for suction separately. The connecting pipe is made of TPE polymer material thin hose, and the size of the connecting pipe is 3.2mm-4.5mm in outer diameter. , inner diameter 2.1mm-3.2mm. A collecting pipe 4 is arranged at the bottom end of the connecting pipe, and a collecting pipe suction hole 5 is arranged on the collecting pipe. Even suction. Control valves are set in each connecting pipe, the control valve is a pneumatic solenoid valve 6, and the pneumatic electromagnetic valve can be arranged at the collecting pipe suction hole 5 position where the connecting ...

Embodiment 2

[0051] Such as Figure 6-7 As shown, the method for engraving an optical fiber fabric using the laser engraving workbench of the optical fiber fabric of Embodiment 1 includes the following steps:

[0052] (1) Take ordinary textile fibers as warp yarns and optical fibers as weft yarns, interweave them, and obtain optical fiber fabrics required for engraving after weaving;

[0053] (2) Heating the distilled water to 70-80°C to generate water mist, spraying the water mist on the surface of the optical fiber fabric for wetting treatment, since the optical fiber is glass (Si0 4 ) Silicon-oxygen tetrahedrons are connected to each other. After absorbing water vapor on the surface of the optical fiber, a hydrolysis reaction occurs slowly, which leads to the breakage of the silicon-oxygen bond in the original network -Si-0-Si-, and the bridging oxygen becomes a non-bridging oxygen. The result is cracks in the glass, and the cracks continue to grow;

[0054] (3) Fix the fabric process...

Abstract

The invention relates to the technical field of laser engraving of optical fiber textiles, in particular to a laser engraving workbench and method for optical fiber fabric. The laser engraving workbench for the optical fiber fabric comprises a workbench surface, a suction device, an air conveying structure; air suction holes are formed in the workbench surface; the air conveying structure is used for connecting the air suction holes and the air suction device; and an air conveying area of the air conveying structure is adjusted according to the area of the optical fiber fabric on the workbench surface. According to the laser engraving workbench for the optical fiber fabric, the multiple independent air suction holes are formed in the workbench surface, the situation that the suction force of the laser engraving workbench is uniform is guaranteed, meanwhile, opening and closing of the corresponding air suction holes can be properly adjusted according to the area of the optical fiber fabric, and use is flexible; and before engraving, water mist is sprayed to the optical fiber fabric, so that microcracks on the surface of fiber are continuously expanded, subsequent laser engraving is facilitated, and the engraving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of laser engraving of optical fiber textiles, in particular to a laser engraving workbench and method for optical fiber textiles. Background technique [0002] With the development of textile technology, functional and intelligent textiles will be an important trend in the development of textiles in the future. The development of luminous textiles has created more fashion and personalization of smart textiles in the future, and it also has great potential in the field of smart wearables. For the appearance and performance treatment of optical fiber fabrics, such as the demand for pattern engraving methods arises at the historic moment. [0003] Laser engraving technology can be used to directly engrave patterns on textiles, with high engraving efficiency and fine patterns, which are widely used in textile design. However, this pattern engraving method has great limitations for the optical fiber fabric obta...
