As shown in fig. 1, a flowchart of steps of a method for manufacturing a rear shell of a terminal device provided in an embodiment of the present application includes the following steps:

step S110: a substrate for fabricating the back shell is provided.

In the examples of the present application, the substrate is glass having an antiglare function. The substrate may be purchased directly from another manufacturer, or may be manufactured through steps S111 and S112. Specifically, as shown in fig. 2.

Step S111: a glass substrate is provided.

Step S112: and carrying out surface treatment on the glass substrate by using a polaroid to obtain the base material of the rear shell.

In this embodiment, a large-sized glass substrate is directly subjected to a surface treatment of a polarizer. By the operation, the link of sending the glass substrate to other manufacturers can be omitted, so that the time for manufacturing the rear shell of the terminal equipment is saved.

Step S120: printing a protective layer on the substrate to form an intermediate member.

In this embodiment, since the substrate is not cut into small-sized substrates when the protective layer is printed on the substrate, the problem that multiple times of small-area printing is required when the protective layer is printed because the substrate is cut into small-sized substrates in the operation of this step in the prior art can be avoided, thereby saving the time for printing the protective layer. In addition, the protective layer is printed on the area of the glass substrate subjected to the surface treatment of the polarizer, so that the area of the rear shell, which needs to retain the surface treatment effect of the polarizer, is effectively protected.

Step S130: and cutting the intermediate piece into a rear shell with the size matched with the terminal equipment.

In this embodiment, the middle part is cut into a plurality of rear cases according to the size of the terminal device.

Step S140: and processing the rear shell according to the specification of the parameters of the rear shell by using a numerical control machine tool.

In this embodiment, the related processing of the numerical control machine tool is performed according to the specification of the rear shell product.

Step S150: and polishing the periphery of the rear shell.

In this embodiment, the periphery of the rear housing is subjected to edge polishing treatment, so that the periphery of the rear housing has an arc surface effect.

Step S160: and removing the protective layer on the rear shell by adopting a cleaning agent.

In this embodiment, the cleaning agent comprises an alkaline cleaning agent.

Step S170: and tempering the rear shell by a physical method or a chemical method.

In this embodiment, the tempering treatment of the rear shell by a physical method specifically means that the rear shell is heated to a suitable temperature and then rapidly cooled to rapidly contract the surface of the rear shell to generate compressive stress, and the middle layer of the rear shell is slowly cooled and cannot contract in time, so that tensile stress is formed and the rear shell obtains high strength. Generally, the higher the cooling strength, the greater the strength of the backshell.

In addition, the tempering treatment of the rear shell by a chemical method specifically means that the surface composition of the rear shell is changed by a chemical method, and the surface lamination stress is increased, so that the mechanical strength and the thermal stability of the rear shell are increased. Since this method is to reinforce the back shell by ion exchange, it is also called ion exchange reinforcement.

Step S180: a membrane is attached to the front face of the rear housing.

In this embodiment, the film mainly bears various visual effects, and is designed by UV transfer printing textures which are overlapped on one side or two sides. The color of the membrane is also a single color or a gradient color.

Step S190: and carrying out anti-fingerprint treatment on the front surface of the rear shell.

In this embodiment, the anti-fingerprint treatment mainly includes the use of a surface treatment agent. By using the anti-fingerprint treatment, dust and fingerprints adhered to the surface of the rear case can be reduced, so that the rear case can be more rapidly cleaned, and surface friction of the rear case can be reduced.

The base material in the method is not required to be cut into small-sized base materials firstly, but the protective layer is directly printed on the base material, so that the time for printing the protective layer can be effectively reduced. In addition, the method further comprises the step of carrying out surface treatment on the whole glass substrate through the polaroid, and external processing is not needed, so that the time for manufacturing the rear shell is saved.
