Step S2011 is already described in step S1011, and will not be described herein.
Step S102, engraving the engraving panel bonded with the transparent hard panel through glue through a three-dimensional embossment digital model by a numerical control machine tool.
The engraving panel is adhered with the transparent hard panel through glue, and mainly aims to prevent the engraving accuracy from being influenced by the fact that the engraving panel is stressed and tilted or deformed when the numerical control machine tool engraving the engraving panel. The transparent hard panel has a certain hardness and is transparent or semitransparent so that light rays can pass through the transparent hard panel when the bottom light is arranged.
Preferably, in step S102, before the engraved panel bonded to the transparent rigid panel by glue is refined by the numerical control machine tool through the three-dimensional relief digital model, the method further includes:
Step S301, coating transparent glue on the engraving panel, and attaching the transparent hard panel to the engraving panel through the transparent glue. The engraving panel is connected with the transparent hard panel through transparent glue so as to improve the strength of the engraving panel during engraving of the digital machine tool; meanwhile, the carving panel can be a wood sheet, a certain penetrating effect is achieved, different textures can be achieved, and the textures can be natural textures or textures obtained after post-processing of the process are adopted, so that the display effect after light transmission is improved. Wherein, in order to reduce the transitional effect between transparent hard panel and the sculpture panel, prevent that glue from producing the bubble, can produce the glue texture through the scraper blade when the sculpture panel rubberizing, make transparent hard panel and sculpture panel be connected through the glue texture, reduce the production of bubble.
Preferably, in step S301, after the transparent hard panel is attached to the engraved panel by the transparent glue, the method further includes:
step S304, discharging bubbles between the engraving panel and the transparent hard panel.
When the transparent hard panel is attached to the carving surface plate, bubbles possibly exist between the transparent hard panel and the composite plate, and in order to improve the overall display effect of the composite light-transmitting panel, the bubbles between the carving surface plate and the transparent hard panel are required to be discharged. The discharging mode can be a mode of vacuumizing by a vacuum pump to remove bubbles or a mode of extruding bubbles by a scraper.

And (3) attaching one side, far away from the transparent hard panel, of the engraving panel after the engraving to the perspective panel, wherein the perspective panel has light permeability so that patterns displayed on the engraving panel due to different permeabilities can be seen through the perspective panel after bottom light passes through the engraving panel. Wherein, because there can be the burr in the sculpture panel between the engraving point after the cnc engraving, keep away from transparent hard panel one side and perspective panel laminating with the sculpture panel to pour into between sculpture panel and perspective panel and solidify the glue into, can gather together after the burr absorbs to solidify the glue, when less burr, can increase the joint strength between perspective panel and the sculpture panel, and promote the display effect of compound printing opacity panel.
In order to improve the display effect of the composite light-transmitting panel; preferably, in step S103, after injecting the setting glue between the engraved panel and the perspective panel after the engraving, the method further includes:
And step S404, discharging bubbles between the engraving panel and the perspective panel.
After the setting glue is injected between the transparent panel and the engraving panel, bubbles may exist between the transparent panel and the composite board, and in order to promote the overall display effect of the composite light-transmitting panel, the bubbles between the engraving panel and the transparent panel need to be discharged. The discharging mode can be a mode of vacuumizing by a vacuum pump to remove bubbles, or a mode of extruding bubbles by a scraper, or a mode of standing the side provided with the groove or the injection hole upwards to automatically remove the bubbles.
Preferably, step S103, injecting a setting glue between the engraved panel and the perspective panel after engraving, specifically includes:
And forming grooves or injection holes on the side edges of the engraving panels, and injecting the setting adhesive between the engraving panels after the engraving and the perspective panels through the grooves or the injection holes. In the engraving process of the engraving panel, the periphery is not subjected to engraving by a numerical control machine tool, so that the setting glue is conveniently injected between the engraving panel and the perspective panel after engraving, a groove or an injection hole is formed in the side edge of the engraving panel, and the setting glue is injected between the engraving panel and the perspective panel after engraving through the groove or the injection hole. Wherein the recess or injection hole may be one or more.
After the grooves or the injection holes are sealed, the transparent hard panel of the composite light-transmitting panel injected with the solidified glue is horizontally placed downwards, burrs of the carved panel after being carved can be attached and gathered again, and the display effect of the composite light-transmitting panel is improved. The setting glue is hardened after setting, so that the light transmittance of the composite light-transmitting panel can be improved. Meanwhile, two sides of the composite light-transmitting panel injected with the solidification glue can be clamped by the clamping plates, the grooves or the injection holes are placed upwards, so that bubbles in the solidification glue can automatically float upwards, and the bubbles are pumped out by a vacuum pump when necessary. Placing the transparent hard panel of the composite light-transmitting panel injected with the setting glue downwards and horizontally; or clamping two sides of the composite light-transmitting panel injected with the solidified glue through clamping plates, and placing the grooves or the injection holes upwards; can prevent the coagulation glue from extruding the perspective panel during coagulation.
Preferably, the engraved panel is a colored flexible panel.
The engraving panel is a colored flexible panel, and the flexible panel can be a colored flexible panel or a wood flexible panel, for example, oak or basswood with better natural texture display effect is used, so that the display effect of the composite light-transmitting panel is improved.
Preferably, the flexible panel is a wood veneer.
