Aiming at the defects in the prior art, the invention aims to provide a decorative plate with a light-transmitting laser engraving symbol, which ensures the strength and beautifies the appearance.
In order to achieve the purpose, the invention provides the following technical scheme: including substrate and printing opacity piece, the substrate material be PC + ABS and be provided with the light trap, the light trap including being located the light trap and with the light trap shape consistent's light-transmitting part, light-transmitting part surface be provided with radium carving symbol area, its characterized in that: and the distance between at least part of the light-transmitting part edge and the edge of the laser carving symbol area is less than or equal to 0.08 mm.
By adopting the technical scheme, when the edge of the light-transmitting part is overlapped with the edge of the laser carving symbol area, the bonding line can be completely hidden, and meanwhile, the strength of the decorative plate is ensured, but the processing error of the laser carving machine is limited, so that the laser carving allowance of 0.08mm is reserved, the laser carving machine cannot be processed outside the light-transmitting part, when light passes through the light-transmitting part or is influenced by the outside, even if the laser carving allowance exists, because the distance between the edge of the light-transmitting part and the edge of the laser carving symbol area is small and the length of the bonding line is shortened, the visual field can be obstructed, the bonding line cannot be observed easily, and a better appearance can be obtained, in addition, in consideration of the processing efficiency, the light-transmitting part of a small symbol is integrated with the light-transmitting part of a large symbol, the connection position is often larger than the laser carving allowance of 0.08, and at least part of the laser carving allowance is limited to be 0.08.
The invention also provides a processing method for processing the decorative plate, and the following steps are provided: a, a double-color injection molding machine closes a first front mold and a rear mold and then injects PC, and divides the mold after forming a light-transmitting piece; b, rotating the rear mold by the double-color injection molding machine, enabling the rear mold to correspond to the second front mold, closing the molds, injecting PC + ABS, and dividing the molds after the base materials around the light-transmitting piece are molded; c, removing the finished product by a double-color injection molding machine; and d, processing the symbol in the laser etching symbol area by adopting a laser etching machine.
By adopting the technical scheme, on one hand, the double-color injection molding machine is adopted, the rear mold is used as a carrier to be respectively subjected to injection molding with the first front mold and the second front mold, a finished product is not separated from the rear mold and is more suitable for processing the light transmission part with irregular edge, the precision of the finished product is higher, meanwhile, when one rear mold is transferred to the second front mold after the step a is completed, the step a is carried out by the other rear mold corresponding to the first front mold, and the processing efficiency is greatly improved; on the other hand, because often have many radium carving symbol region on the plaque, unified by radium carving machine carry out radium carving after the completion of moulding plastics, further improve machining efficiency.
The invention is further configured to: the laser engraving machine is a CCD laser engraving machine.
By adopting the technical scheme, the CCD laser etching machine, namely the visual laser etching machine, is required to be adopted, the processing error is less than 0.05, so that the processing requirement when the distance between the edge of the light-transmitting part and the edge of the laser etching symbol area is less than or equal to 0.08mm is met, and the processing efficiency can be improved while a high-quality finished product is stably obtained.
