Description

technical field [0001] The present invention mainly relates to the technical field of heat transfer processing, and more specifically relates to a method and device for making fully automatic wood board heat transfer technology based on image recognition and laser processing technology. Background technique [0002] Heat transfer, also known as pyrography, is an extremely precious and rare painting in my country. The processing method of heat transfer of wooden materials is to use a special electric soldering iron (pen) on wooden materials (wood, bamboo chips, bark, etc.), by adjusting the heat generation of the soldering iron (pen), press the pressure and time to make the material A discoloration reaction is produced, and then light, dark brown and black marks are formed on the surface of the wooden material, thereby forming a wood heat transfer with a unique drawing style. Finally, spray transparent paint to protect the screen, moisture and mildew; the existing wood heat t...

Problems solved by technology

[0011] The technical problem to be solved by the present invention is to provide a method and device for making heat press on wood, adopt a fully automatic heat press production method based on image processing technology, laser technology and numerical control technology, and propose a production device for heat press on wood, Convert the heat transfer image to be completed into a grayscale image through image processing technology, and record the relationship between the pixel size position and the grayscale value; establish the grayscale value and the laser irradiation intensity and laser irradiation of the laser head on the wooden board through experiments. Time, laser irradiation distance process parameters corresponding table, finally, through the numerical control technology to control the three-dimensional space movement of the laser head above the wooden board, use the laser point to shoot the wood, burn the wood surface, form the heat transfer pattern, and then complete the production of the wood board heat transfer, Finally, spraying transparent paint to protect the processing pattern can solve the problem of manual completion of heat transfer production in the prior art, low production efficiency, unstable production quality (very easily affected by the personal status of the heat press maker), inability to meet personalized custom production, It is difficult to meet the disadvantages of mass production of wood heat transfer
