From leaning, automation to digital and intelligent, Midea's home air -conditioning Shunde plant has increased production efficiency by 28%, unit costs decreased by 14%, and order delivery cycle was shortened by 56%. Since 2020, four factories including Midea's home air -conditioning Guangzhou Factory have won the honor of the "Lighthouse Factory" representing the leading standards of global manufacturing. In just two years, one of the key to the rapid "mass production" lighthouse factory is the key to the long -term persistence of lean. To this end, the Guangdong Economic Science and Education Channel visited the United States in depth, looking for a smart manufacturing key behind a household air conditioner.
15 seconds to assemble a air conditioner
In the Mimimen's home air -conditioning intelligent chemical factory in Shunde District, Foshan City, Guangdong Province, an air conditioner can be assembled every 15 seconds. Compression, assembly, quality inspection and other links are completed in the state of rarely requiring artificial intervention. The automation rate of this household air conditioner is a leading production line worldwide. Its average daily output exceeds 50,000 units and an average monthly output exceeds 1.2 million units. Compared with the intelligent transformation, its output and output value have been three times doubled. There are many.
"This line that turned out to be behind us requires a lot of manual operation. Now through the robot, we successfully divide the original output of the original line into two back -end loading lines, which is equivalent to us The successful output has been increased by 50%. "Sun Shibo, the head of Midea's home air -conditioning Shunde Factory Lean Manufacturing, said in an interview with reporters," The peak of the product is increasing every year, and the delivery period of the product is also decreasing every year. The advantage is obvious. "
Long -term investment and exploration
Intelligence to improve quality and efficiency, Midea Group intelligent manufacturing expert Gu Xiaochun said in an interview that this was not achieved overnight, but long -term investment and precipitation. "To achieve digitalization and intelligence, we must first give lean. As of the end of last year, Midea has invested almost 2.8 billion yuan in terms of leaning, and the group's investment in digitalization has reached 12 billion yuan. The "Three -way" process finally realizes intelligent manufacturing. "
Midea's lean development can be traced back to 2003. At that time, the benchmark of lean at that time was Toyota model, that is, TBS. In the 1970s, Toyota, Toyota in Japan, stood out in the automotive industry by refining the summary of the leaning model, which caused the industry's pursuit of lean. Midea also starts from learning Toyota model, but the effect is not ideal. It can only find a model that suits you by exploring and combining its own characteristics and situation. "At the beginning of the promotion of lean, because the system has not been formed, the concept of the traditional manufacturing of employees has changed slowly, and the effect is not significant, resulting in the confusion of employees." Gu Xiaochun recalled.
Until 2016, Midea began to learn from Danna's lean model, that is, DBS. DBS can be described as a improved version of TBS. It has standardized and improved TBS. It has refined more than 80 lean improvement tools. This model is used on hundreds of companies they have acquired. Finally The capital return rate comes more than 50%.
Standing on the shoulders of the giant, Midea gradually precipitated a set of models that really suits you in confusion and setbacks -MBS (Midea Business System).
Mass production lighthouse factory, embrace future intelligence manufacturing
In December 2015, MBS's household air -conditioning Shunde Factory was implemented, and it was rapidly promoted to 34 domestic factories in the United States in the next two years. After several years of exploration, Midea refined its "Golden Triangle" of its own MBS model, that is, strategic deployment, daily management and maintenance, and talent breeding.
Especially for talent breeding, this is also an important reason for beauty to quickly promote leaning in 34 domestic factories. Midea divides the lean talents into three categories, green belts, black belts, and black belt coaches. At present, Midea has more than 10,000 talents, including more than 20 black belt coaches, more than 1,300 black belts, and more than 8,000 green belts.
In addition to continuously cultivating lean talents, Midea itself has developed a lean evaluation system used for internal factories.
In addition, Midea's reference to Schneider has established a lean evaluation system. The entire system includes 11 professional dimensions, including smooth flow, pulling, automation, and informatization.
"Leanization is a management model that cannot be simply regarded as a tool. To do a good job of leaning, we need to change our management methods and thinking mode. Everyone from top to bottom has lean thinking and ideas. Whether a company can successfully do a good job of leaning. "Gu Xiaochun said.
In October last year, Midea Group officially released the group's green strategy to incorporate the construction of green factories and zero carbon factories into planning and construction, continuously enhance Midea's intelligent manufacturing level, and embrace future intelligence. On March 30 this year, the World Economic Forum (WEF) announced the list of the eighth batch of global lighthouse factories. The Midea refrigerator Jingzhou Factory and Midea washing machine Hefei Factory were successfully selected. At this point, 4 factories have become "lighthouse factories".
As of now, from the first -class manufacturing team to the ordinary workshop team, Midea MBS has been fully implemented in various factories around the world. The ability of Midea to be lean, automation, digital and intelligent, allows them to set the goal of achieving the level of 30 factories to achieve the "lighthouse factory" before 2025.
Through the original MBS, Midea establishes a "beauty, a system, a standard" intelligent manufacturing system to ensure the stable and orderly monitoring of the process quality and the quality of the whole process, and achieve standardization of production. The Meiqing Industrial Internet Platform has created a series of "research, production, sales, and supply" a whole set of industrial software to achieve external empowerment and equipped with the ability to combine hard and hard, so that companies on the platform have less "detours". A total of more than 400 large enterprises and more than 210,000 industrial enterprises have been served, creating intelligent factories for a large number of Chinese companies, helping technology and manufacturing power.
The beautiful textile industry in the air -conditioning and air -conditioning market is a traditional industry in China. It is a variety of textile industries needed by natural and chemical fibers through textiles, weaving, dyeing, classification and other processes. There are three main processes in the textile printing and dyeing industry: textile, weaving and dyeing.
What conditions do textile industry air conditioners need to meet?
In order to ensure the normal operation of the textile industry air -conditioning dust removal system and save energy to a greater extent, the operation and management of the textile air -conditioning dust removal system is very important. Good operation management can not only give full play to the function of the air -conditioning dust removal system, create a good production environment, improve labor conditions, promote the smooth progress of textile production, but also save energy and reduce production costs. The main task of the operation and management of textile air -conditioning dust removal systems is based on the changes in climate conditions in various regions and the requirements of the workshop for temperature and humidity. Status, give full play to its role. Otherwise, even if there is a complete system design and good equipment, it is impossible to play its due role.
Under the premise of ensuring the temperature and humidity requirements of the workshop, a reasonable, economic and energy -saving air -conditioning system should be selected. A wind -return system should be adjusted by a variable air volume.
Each main workshop adopts a dual fan system to ensure that the airflow of the workshop is stable and the temperature and humidity difference is small. At present, the single fan system can be used for workshop preparation.
According to the characteristics of the textile factory, the air treatment uses water spray washing, and the large air supply volume of each set of washing rooms should be less than 150,000 meters 3/.
