“Exciting†the “light†of the change in the home appliance industry
Recently, who has not had a few favorite things in the shopping cart? Just wait for the "Double Eleven" to unplug these grasses. For ordinary consumers, the price, the red envelope, the coupons... This day is more like a holiday; for the business, this day is a hard battle, especially for home appliance practitioners.
“Exciting†the “light†of the change in the home appliance industry
From the traditional offline retail to the escalation of e-commerce warfare, from the simple pursuit of quantity growth to the pursuit of quality process guarantee, from the traditional processing technology to the application of emerging laser technology, the entire home appliance industry is undergoing profound changes. Today, we are going to explore the laser technology of one of the four major inventions of the 20th century with the atomic energy, semiconductor and computer, and see what new changes it has brought to the home appliance industry.
Laser processing technology is a processing technology that uses laser beam to interact with materials to cut, weld, surface, punch and micro-machine materials (including metals and non-metals). Because laser processing is non-contact processing, it has small damage to the workpiece, 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, for example, in washing machines. Cutting, welding and alloying of refrigerators, air conditioners, etc., drilling, cutting and marking of plastic parts.
Laser marking: In the traditional way, the parameters of household electrical appliances are commonly used in PET, PVC, coated paper and other materials. It is necessary to make labels first, then manually paste them, and the efficiency is low, and the labels are easily torn, pasted, bubbled, etc. A large amount of consumables such as label paper are required, which is expensive, not environmentally friendly, and requires an increase in manpower and work time, and a high production cost. The original plastic label is replaced with a laser mark, and the processing method is changed from the traditional manual labeling to the laser automatic marking, which can improve production efficiency, save manpower and a large amount of consumables, and is also more environmentally friendly and efficient.
The home appliance giant Midea Group began to use the laser marking technology of Huagong Laser to complete the automation transformation of the air-conditioning production line a few years ago. Subsequently, Haier, TCL, AUX and other first-class home appliance manufacturers have cooperated with laser companies to actively expand the laser application in the field of white goods, bringing a new label nameplate laser processing solution for home appliances such as air conditioners, refrigerators, washing machines and remote controls. Program.
Laser cutting: Laser cutting is the process of focusing energy into a small space, using high-density energy for non-contact, high-speed, high-precision cutting methods. Compared with the traditional shearing process, it has higher cutting precision, lower roughness, higher material utilization and production efficiency. Especially in the field of fine cutting, laser cutting has the advantage that traditional cutting can't match. .
Laser cutting is mainly used in the electrical industry for the cutting of sheet metal parts in the appearance of sheet metal parts and the installation of complete electrical components. In household electrical appliances, sheet metal parts account for almost 30% of all product parts. Traditional techniques such as cutting, chamfering, opening and trimming are backward, directly affecting product quality and production costs. Because of its “contactless machiningâ€, the laser cutting machine eliminates the need for mold opening and saves costs. The processing graphics are made by software and have various patterns, such as metal fittings for air conditioners, metal casing cutting, and cooling stencil cutting at the bottom or back of the refrigerator. , punching; blade cutting of juicer, etc. are all through this laser cutting technology to effectively improve product quality, reduce production costs, reduce labor intensity, and bring better production benefits to manufacturers.
Laser welding: In the home appliance industry, argon arc welding or fiber brazing is traditionally used, but the traditional welding process has a poor processing surface, which brings great processing difficulty to the next process, while the appearance of laser welding is It is smooth and flat, has small thermal deformation, saves materials, and can be finished by simple grinding or polishing after welding.
As early as 5 years ago, the first Haier crystal drum washing machine with laser seamless welding technology was launched. Haier became the first domestic washing machine brand to contact and start to promote this technology. Compared with the traditional washing machine, the 8mm gap generated by the rivet riveting, the precision of the inner tube weld of the Haier crystal drum washing machine is improved by 14.5 times, reduced to 0.55mm, and only 10 hair thickness. It is worth mentioning that with the laser seamless welding technology, the inner cylinder strength of the crystal has also been greatly improved. In the tensile test, the crystal inner cylinder can withstand 3.5 times of the pulling force of the ordinary inner cylinder, and the joint is firmer, which can support the ultra-high speed of the FPA direct-drive inverter motor at 1600 rpm, which greatly improves the laundry washing ratio. Today, five years later, more than 95% of Haier drum washing machines have been laser welded seamlessly. Some insiders believe that Haier has actually completed the historic breakthrough in the inner tube welding technology of the washing machine industry.
"Intelligent" and "high-end" have become the key words in the upgrading of the home appliance industry. In fact, this is not only the new development goal of the home appliance industry, but also the path and pursuit of the entire Chinese economy and Chinese manufacturing. At present, the utilization rate of laser technology in home appliances is not high enough, but this process has been gradually recognized and recognized by manufacturers. It is believed that in the future, the application of laser technology in the home appliance industry will become more and more extensive, and its development potential and market opportunities. It is immeasurable.
