stamping
When Apple's early product iPhone4 came out, the gorgeous texture and high-quality touch of the metal body received praise from the industry. The metal fuselage became a technological trend. In the past two years, the emergence of ceramic and glass cases has reduced the mobile phone to some extent. The metal processing process in the manufacturing process, but its stable and reliable frame structure is still the first choice for the metal middle frame process.
In the processing of metal middle frame, metal stamping molding process is indispensable. In the early stage of the industry, the metal stamping process is controlled manually by a stamping machine tool. At present, the stamping production line of mobile phone shell composed of stamping robots has become popular in the industry.

Polishing
The metal shell obtained by the stamping process needs further surface treatment by grinding and polishing to reduce the surface roughness of the workpiece to obtain a bright and flat surface. The polishing process of the mobile phone housing is mainly mechanical polishing, and the manner in which the CNC machining is used accounts for a major part. The use of industrial robots for automatic polishing is also one of the polishing processes.

Spraying
A large number of spraying processes existed in the era of mobile phone plastic case. In addition to the mobile phone case, the notebook computer case, toy case, and home appliance case were once applied to a large number of surface colors using a spraying process. Spraying can provide a variety of brilliant color effects for mobile phone shells (including protective shells) to meet consumers' increasingly higher appearance requirements.

Assembly
Mobile phone assembly is the final step in the product forming process. Mobile phone assembly is not only labor-intensive but also technology-intensive. There are hundreds of production lines and a large number of assembly employees. Mobile phone assembly plants such as Foxconn, Backgammon, and Huawei are busy with ten thousand people. Tens of thousands of workers have caused difficulties in management and recruitment. Foxconn has been seeking machine substitutions for many years, and its million-year robot factory was once famous.

The mobile robot assembly process is based on light-load multi-joint, SCARA, and rectangular coordinates, and it also has high requirements for anti-static and dust-free environments.
Solder
In the mobile phone industry chain, welding processes exist widely in motherboard welding, FPC welding (liquid crystal screens, motherboards, etc.), and cable welding processes. In the mobile phone industry chain, welding processes are generally called soldering, and soldering operations are relevant. Robots are also called solder robots.
The process of soldering is to ensure that the two independent electronic devices are connected to each other. The soldering process needs to ensure the welding effect. In addition to the appearance, the connection needs to be guaranteed to be stable, and no leakage soldering or poor connection can occur. The traditional manual welding not only has uneven quality in welding, but also requires a lot of manpower. It is also one of the goals of major manufacturers to gradually explore the artificial replacement of the soldering process.

At present, fewer multi-joint industrial robots are used for soldering, and SCARA robots and desktop robots are the mainstream.
Dispensing
Dispensing technology widely exists in the electronics industry represented by the mobile phone industry. Dispensing can play a role of cementation, closure, and connection. During the dispensing process, due to the fluid properties of the glue, there are problems such as uneven glue, overflow of glue, and insufficiency of glue sealing due to artificial glue. In the industry, automatic dispensing equipment mainly based on glue was introduced earlier.
Similar to the soldering robot, the dispenser is a desktop type rectangular coordinate robot.

Hit the screw
The basis of mobile robots for screwing robots is also a desktop robot. A screw robot is constructed by adding a screw driver at the end of the desktop robot.

The screwing process mainly exists in the assembly process of mobile phones and is the main means for the stable connection between the mobile phone mainboard and the middle frame.
AGV
Automated guided vehicle (AGV) is mainly used in the mobile phone industry for material handling of production lines and is one of the important equipments that make up the production line logistics. The application of AGV in the mobile phone industry is relatively early. At present, mainstream AGV manufacturers have material handling solutions for the mobile phone industry chain.

In addition to material handling on the production line, such as PCB manufacturing, material handling in storage, etc. are also important applications of AGV in the mobile phone industry chain.
Clean Robot
Cleanliness is very important for the mobile phone industry, especially the chip and panel industries upstream of the mobile phone. The lack of cleanliness will have a significant impact on the yield rate of these products. Therefore, there is a need for robots suitable for working in a clean room in a clean room.

Cleaner robots are used for wafer handling in the semiconductor industry and panel transportation in the panel industry.
Logistics
Logistics is usually a part that is neglected by the industry. However, its cost is one of the highest areas except for energy and factories. Effectively reducing logistics costs is equally important for improving corporate profits.
In the logistics sector, industrial robots are widely used in the logistics of loading and unloading, unpacking/packaging, picking, sorting, sticking accessories, firewood/puppeting and other links. Among them, AGV and multi-joint industrial robots have many application cases.
The logistics sorting robot once fired on the Internet. As a representative of China’s scientific and technological advancement, it once landed on the CCTV promo. In JD’s internal logistics sorting process, the final sorting process, represented by mobile phone products, used the program.

In addition to logistics sorting, similar to the process of mobile phone shipments, frequent unpacking, unpacking, packing, sticking a single process also appeared in the presence of multi-joint industrial robots.
At present, industrial robots are mainly used in the automotive industry. As the demand for industrial robots in the automotive industry slows down, in the future, industrial robot manufacturers will look to 3C electronic fields with more development potential, and the mobile phone industry will be the 3C electronic industry. The main application areas of industrial robots.
