Program overview Laser processing is to irradiate the laser beam to the surface of the workpiece, and use the high energy of the laser to cut and melt the material and change the surface properties of the object. Because laser processing is a non-contact processing, it has little damage to the workpiece, has the advantages of high efficiency, no pollution, high precision, and small heat affected zone. Therefore, it is very suitable for the manufacture of household appliances that require light weight and beautiful appearance. Kind of metal and non-metal processing, especially high hardness, high brittleness, and high melting point materials. For example, it is used in the cutting and welding of alloy cabinets of washing machines, refrigerators, air conditioners, deep carving and cleaning of molds; laser coating anti-rust on the inner and outer walls of microwave ovens, disinfection cabinets, etc.; cladding of metal structures of large household appliances after wear; Marking of operation instructions and brand logos; drilling and cutting of metal parts and plastic parts; micro-drilling and micro-welding of internal circuit boards of electrical appliances; laser additive manufacturing (3D printing) used in the production of valves and other core parts. Advantages of the solution 1. From the perspective of the market, laser technology is currently being paid attention to all over the world, especially in Germany, the United Kingdom, the United States, Japan and other countries, which are vigorously researching, developing and applying laser technology in an attempt to compete for the world market. The key to achieving high-efficiency production and high-end quality for domestic home appliances is to reform the production line and adopt new technological processes. Therefore, the application of laser processing in the production of home appliances is a strategic need, a situational need, and a market need. We should keep pace with the times, integrate with world technology, enhance international competitiveness, and share the technological "cake". 2. From the aesthetic point of view, people's demand for home appliances not only needs to be durable, but also beautiful. Using laser technology to mark the graphics, text, sequence, etc. on household appliances, the processing is fine, clear and wear-resistant. Home appliances processed with laser technology are easy to be accepted by the market, and more favored by consumers! Compared with traditional mechanical engraving, chemical corrosion, screen printing, ink printing and other methods, laser marking has low cost, high flexibility, and can be controlled by a computer system. The laser marking on the surface of the workpiece is firm and permanent. Its outstanding features. The articles engraved by the laser marking machine have fine patterns, and the minimum line width can reach 0.04mm. The marking is clear, durable and beautiful. 3. From the perspective of technology, traditional sawing, mechanical cutting, oxygen acetylene cutting torch, electric spark cutting, toothless saw cutting, water jet (including emery) cutting, plasma cutting torch and other processes are gradually being replaced by modern laser technology . Taking laser cutting as an example, because the traditional mechanical knife is replaced by an invisible beam, the mechanical part of the laser head has no contact with the work, and it will not scratch the work surface during work, and the speed is fast, and the cut is smooth and flat. Generally, no subsequent processing is required; the cutting heat-affected zone is small, the plate deformation is small, and the slit is narrow (0.1mm~0.3mm); the incision has no mechanical stress, no shearing burr; high processing accuracy, good repeatability, and no damage to the material surface; CNC It can be programmed to process any plan, and it can cut large-scale whole boards without opening the mold. It is economical and time-saving. It is very suitable for the production and processing of home appliances.
