Description

Processing device for the metal casing of the smart stylus

technical field

The invention relates to the field of smart stylus, in particular to a processing device for the metal casing of the smart stylus.

Background technique

With the development of mobile communication technology, touch-screen portable electronic devices are becoming more and more popular among users. Touch-screen portable electronic devices on the existing market usually use an attached stylus to perform information input operations.

The stylus provided with the existing electronic device is built into the electronic device for convenience of carrying and not easy to lose. When the stylus needs to be used, the stylus is pulled out from the electronic device. However, the electronic device has many internal components and limited assembly space, and the built-in stylus occupies a certain space, and the built-in stylus is small in size and inconvenient to use. Most of the metal shells of the existing smart stylus are made of plastic, and the plastic mobile phone shell has poor wear resistance, and scratches or even fading will appear after a period of use. For this reason, metal casings are required, such as stainless steel, aluminum alloy or titanium alloy casings. These metal casings are very popular among consumers because of their good wear resistance and exquisite appearance. However, the existing metal shell of the smart stylus is limited by the processing method, and the cost remains high, so it is difficult to be widely used. Due to the need to install other parts, it is necessary to design a lot of button positions, column positions, west arc angles, high and low steps, etc. If it is made by cutting a whole piece of material, it will take a long time and cost high if it needs to be processed in a CNC machine tool machining center. resulting in an extremely expensive final product.
