First of all, we saw the SMT production line of Xiaomi 9, which is where the mobile phone motherboard is processed. Welding the components on the mobile phone to the PCB motherboard, almost all the work here is done by an automatic manipulator, and the master is mainly responsible for checking and adding raw materials.
Mobile phone chips, resistors, capacitors and other components are placed on the motherboard by the manipulator according to the specified coordinates, and then the whole motherboard is processed by reflow oven. The manipulator can complete chip mounting and welding very accurately and quickly. A production line can produce 8000 mobile phone motherboards a day, and such an SMT production line has 10 at the same time in Langfang Foxconn.
Then I visited the assembly workshop of Xiaomi 9 mobile phone, and assembled the motherboard, screen, camera, receiver, battery, wireless charging coil and other parts of Xiaomi 9 mobile phone to the mobile phone. In this process, I have been testing whether the assembly process is successful and whether the installed components can work smoothly.
The last step is to install the glass back cover of the mobile phone on the fuselage, and also rely on the precise positioning of the manipulator to attach the back cover to the fuselage. Then write the mobile phone system into the assembled mobile phone. At this step, the assembly of a Xiaomi 9 mobile phone has been basically completed.
The assembled mobile phone does not leave the factory directly, but has to undergo a rigorous stress test. In the aging test workshop, the assembled mobile phone will simulate the heavy use of users and test whether there are software and hardware problems in the mobile phone. The products that have passed the test basically have no software problems.
After that, the mobile phone will be treated with p2i, that is, the surface of the mobile phone will be covered with nano-scale coating, which will make the surface of the mobile phone hydrophobic and prevent the liquid from entering the mobile phone, thus achieving the level of splash prevention. The whole p2i treatment will last for 3 hours.
The last production line is the packaging of mobile phones. When the mobile phone arrives here, it will conduct the final test on the screen, camera and other functions. Then stick a network access license on the back of the fuselage, stick a bar code, stick a screen film, and you can pack it. After a series of complicated technological processes, a Xiaomi 9 mobile phone was assembled.
These produced millet 9 will be temporarily stored in the temporary storage area of the factory and then sent to various sales channels. The person in charge of the factory said that the sales of Xiaomi 9 mobile phones are so hot that the mobile phones produced do not need to be put into storage at all, and forklifts will take the goods away.
By the end of March, the shipment of Xiaomi 9 series mobile phones was 6.5438+0.5 million units, of which Xiaomi 9 mobile phones exceeded 6.5438+0.5 million units. The person in charge of Xiaomi said that the foundry is now working overtime to produce mobile phone products, which is also to provide sufficient supply for the upcoming Xiaomi Rice Noodle Festival.
After visiting the factory, Qiao Tonghu, senior manager of the production management department of the mobile phone department of Xiaomi Group, and Xu, general manager of the public relations department of Xiaomi Group, accepted questions from the media. Everyone is most concerned about the production capacity of Xiaomi 9 mobile phone. The person in charge of Xiaomi said that the problems encountered in the early production are in two aspects. First, the supply of camera modules is relatively small, which limits the overall production capacity. Then the proficiency of the master worker is still improving. By mid-March, the problem of limiting production capacity has been gradually solved, and Xiaomi 9 mobile phone will have enough goods to meet consumers.
Xiaomi 9 is assembled and produced by three domestic mobile phone foundries, including Foxconn in Langfang, Inventec in Nanjing and BYD in Xi 'an. Among them, Langfang Foxconn is responsible for most of the production, and Nanjing Yinghuada has a dust-free workshop, which is mainly responsible for the production of transparent exclusive editions. BYD of Xi 'an has just started to assemble and produce Xiaomi 9 mobile phone.
? By visiting the production line of Xiaomi 9, I learned that Xiaomi and Langfang Foxconn are not only OEM, but also very close partners. At the production site, Xiaomi's logo, slogan or Mi Tu's design can be seen everywhere on the wall. Moreover, many production and processing equipment are also seen on the production line, all of which are provided by Xiaomi. With the close cooperation between Xiaomi and Foxconn, products can enter the market smoothly.
At the same time, we also saw Xiaomi's strict requirements for product quality. The person in charge said that Xiaomi is stepping up the time to optimize the test process. By using the manipulator to improve the test efficiency, it can not only improve the production capacity, but also ensure that every mobile phone delivered to users is a product with guaranteed quality.
? Today, through the continuous efforts of Xiaomi and Foxconn, Xiaomi 9' s capacity climbing has achieved remarkable results. While successfully completing the goal of shipping 6,543,800 units in the first month, Xiaomi 9 is also stepping up the production of two shifts, which should meet the purchasing needs of consumers.
