On a high-speed drum washing machine, a pencil and a coin stand upright on the countertop but "do not move", and the compressor technology is applied to the washing machine, and a heat pump washing machine has been developed, which can dry at 37°C and precisely control the temperature, so that consumers can enjoy the "dry cleaning" experience at home...... As a representative of mainland manufacturing enterprises, Gree Electric has invested in the construction of a washing machine assembly intelligent workshop in Chengdu Xinjin for more than a year, and has recently been recognized as a smart factory in Chengdu in 2023. Today, the reporter walked into the Gree washing machine smart factory and visited the advanced place of its intelligent production line.
Efficiency improvement and product upgrades
Technological innovation makes smart factories more powerful
Walking into the Gree washing machine production workshop, intelligent and automated scenes come into view: the robot arm is wielding powerfully, the conveyor belt is running quickly, and the parts are transferred to the required process in an orderly manner. "All the robots in the production line are developed and manufactured by Gree itself, and a palletizing robot like this can lift a washing machine weighing up to 116 kilograms, which is very powerful. ”
Under the leadership of the relevant person in charge, the reporter came to the international leading washing machine inner drum production line introduced from Italy. According to reports, this production line adopts double workbench interactive continuous production, the welding efficiency is improved, and the welding quality is stable and reliable; the laser welding online full inspection system realizes real-time online detection before, during and after welding, and the pass rate is leading in the industry; the "fishhook type" riveting processing technology, the forming method of "rolling round + stacked edges" improves the riveting efficiency, and the supporting molds are reduced, and the product switching time is greatly improved.
"This highly flexible and automated production line only needs 2-3 people to maintain, such as on/off, debugging, spot checking, etc., which greatly improves the efficiency compared with the semi-automatic production line. The person in charge introduced.
Smart factory not only means the improvement of production efficiency, but also needs products with higher core competitiveness to confirm. In the Gree Smart Factory, the reporter met the heat pump washing machine developed by Gree by combining its superior technology in air conditioning compressors with washing machines.
At first glance, the volume of Gree heat pump washer is as large as that of an ordinary washing machine, but it has the triple function of washing, caring and drying, which integrates the washing machine, heat pump dryer and nursing machine, and one machine completes the washing, drying and nursing of clothes at home.
According to reports, the drying effect of the washing machine largely depends on the heart of the dryer - the compressor. As a well-known air-conditioning manufacturer in China, Gree has been deeply involved in the field of air-conditioning for many years, and is also one of the large-scale air-conditioning compressor specialized enterprises in China. The Gree heat pump washing machine is equipped with Gree dual-rotor inverter compressor technology, and the compressor of the air conditioner is installed in the washing machine, which is simply a "small air conditioner" installed in the washing machine. During the operation of the compressor, the vibration is smaller, the body is more stable, the efficiency is higher, the drying process is heated up faster, the drying speed is faster, and the long-term 37°C heat pump drying is maintained. The heat pump washing machine applies low-frequency torque control technology to keep the compressor running stably at low frequency, and at the same time achieve a low-temperature temperature of 37 degrees, it only needs one kilowatt-hour of electricity for the whole night, saving energy and electricity.
The traditional heat pump dryer drying wool and silk clothes is easy to cause shrinkage damage, while the low-temperature drying technology of Gree Nu Skin heat pump washing machine can basically meet the vast majority of fabrics and clothes on the market. "The low temperature soft air gently dries the clothes, which can not only dry the clothes quickly, but also effectively reduce the deformation of the clothes. The person in charge said.
Policy support to build a platform
Escort the digital transformation of enterprises
In the 2023 Chengdu Smart Factory and Digital Workshop, Gree Electric Appliances in Tianfu Intelligent Manufacturing Industrial Park in Xinjin District was selected as a smart factory, and another 7 workshops were rated as digital workshops.
Among these 7 companies, Daswell and Shifeng have been awarded the top ten typical application cases of industrial Internet in Chengdu. COFCO has two workshops selected as digital workshops at the same time, namely flour processing digital workshop and rice processing digital workshop, and is the only enterprise selected for digital workshops with multiple workshops in this selection.
For CATL's production base in Xinjin, Xinjin Times, digitalization not only brings a series of improvements in production efficiency, but also is one of the core measures to promote energy conservation and emission reduction in factories.
Xinjin Times has applied digital technology extensively and deeply in the whole link of carbon emission reduction in factories, and made every effort to reduce carbon emissions, and was rated as a zero-carbon factory in August this year, becoming the fourth zero-carbon factory of CATL.
In Tianfu Intelligent Manufacturing Industrial Park, another company, Civil Aviation Logistics, has also been awarded the Chengdu Digital Workshop last year. Through the integration of existing technologies and business sectors, civil aviation logistics deepens the intelligent manufacturing of civil aviation baggage system and extends the service chain, and provides airport users with integrated solutions for baggage handling systems in line with their own realities.
In order to promote the digital transformation of the industry, Xinjin District has issued a series of supporting policies. At present, the application of the inclusive policy in Xinjin in the second half of the year has been reviewed, and a total of 9 people in Xinzhu have enjoyed the digital economy youth talent policy, with a total of 64,500 yuan.
"This is the first time that we have applied for the digital economy youth talent policy. Hou Yu, director of the comprehensive management department of Changke Xinzhu, said, "This is thanks to the intelligent technology industry department of the management committee, in August, the management committee mobilized us to declare digital economy enterprises, telling us that this is a precondition for the declaration of digital economy youth talent policy." ”
In August this year, Xinjin District launched the second batch of applications for digital economy enterprises, and the management committee notified key enterprises one-on-one to declare, and finally identified 14 new enterprises, and a total of 40 enterprises have been identified so far, and the digital talents of these enterprises have also enjoyed the digital youth talent policy.
Policy support and build a platform to escort the digital transformation of enterprises. The relevant person in charge of Xinjin District said that it will anchor the goal of "high-quality industrial development", continue to unswervingly implement the strategy of establishing a smart manufacturing district, accelerate the process of "digital transformation and intelligent transformation" of manufacturing enterprises, solidly promote new industrialization, and continuously enhance the new momentum of industrial development.
