From the traditional offline retail to the upgrading of e-commerce war, from the simple pursuit of quantity growth to the pursuit of high-quality process assurance, from the traditional processing technology to the application of emerging laser technology, the entire household appliance industry is experiencing profound development. Change.

Today, what I want to discuss with you is laser technology, which is one of the four great inventions of the 20th century and maintains the same status as the four great inventions of atomic energy, semiconductor and computer. Let's see what new changes it has brought to the household appliance industry.

Laser processing technology

It is a processing technology, mainly referring to laser beam cutting, welding, surface, stamping and micro mechanical materials (including metal and non-metal) interacting with materials. Laser processing has the advantages of non-contact processing, less damage to the workpiece, high efficiency, no pollution, high precision and small heat affected zone. Therefore, it is very suitable for manufacturing light and beautiful household appliances, especially in the kitchen and bathroom industries. For example, cutting and welding of alloy shells and drilling, cutting and marking of plastic parts of washing machines, refrigerators and air conditioners.

Laser marking

Traditionally, the parameter labels of household appliances are usually used for PET, PVC, coated paper, etc. Labels must be made first and then pasted manually, which is inefficient and easy to tear, bias, bubble, etc. A lot of label paper is required. Therefore, it is necessary to have high production costs characterized by high consumption, non environmental protection, increased manpower and operation time. If the original plastic label is replaced by laser marking and the processing method is changed from traditional manual marking to automatic laser marking, the production efficiency can be improved, manpower and a large number of consumables can be saved, and the environment can be more environmentally friendly and efficient. Nowadays, many companies are actively expanding the application of laser in white household appliances,

laser cutting 

Laser cutting is a process of concentrating energy into a small space. This process uses high-density energy for non-contact, high-speed and high-precision cutting methods. Compared with the traditional shearing process, it has higher cutting accuracy, lower roughness, higher material utilization and production efficiency. Especially in the field of fine cutting, laser cutting has incomparable advantages over traditional cutting. In the electrical industry, it is mainly used for cutting sheet metal parts, appearance of sheet metal parts and installation of complete electrical parts. Because of the "non-contact processing", there is no need to open the mold, saving costs. Processing graphics are made by software with various patterns, such as metal accessories for air conditioners and metal cover cutting;

Laser welding

In the household appliance industry, argon arc welding or fiber brazing is traditionally used, but the processing surface of the traditional welding process is poor, which brings great processing difficulties to the subsequent process, while the appearance of laser welding is relatively flat. Small thermal deformation and material saving. After welding, only grinding or polishing can complete the appearance treatment. Haier crystal drum washing machine is the first application of laser seamless welding technology in China. Compared with the traditional washing machine, the 8mm gap generated by rivet riveting increases the welding accuracy of the inner tube by 14.5 times, shrinking to 0.55mm, and only 10 hairs. It is worth mentioning that with the help of laser seamless welding technology, the strength of the inner cylinder of the crystal has also been greatly improved. Some insiders believe that Haier has actually made a historic breakthrough in the welding technology of inner tubes in the washing machine industry

In fact, the application of laser technology in household appliances industry is not only its new development goal, but also the road and direction of the entire Chinese economy and Chinese manufacturing industry. At present, the utilization rate of laser technology in household appliances is not high enough, but this technology has gradually been recognized by manufacturers. It is believed that in the near future, laser technology will be more and more widely used in the household appliances industry, and its development potential and market opportunities are incalculable. Laser processing will improve the value of household appliances and help the household appliance industry to develop toward the high-end of "intelligent manufacturing".
