Production process of mobile phone shell and film pressing device used in production process

Abstract

The invention belongs to the field of mobile phone shell production, and particularly relates to a production process of a mobile phone shell and a film pressing device used in the production process. The production process mainly comprises the following steps of aluminum extrusion, drilling, polishing, paint spraying and film pressing, the film pressing device used in the above production process of the mobile phone shell comprises a workbench, a transverse rod is fixedly connected to the side wall of the upper end of the workbench, and the cross rod is fixedly connected with an air cylinder. According to the production process of the mobile phone shell and the film pressing device used in the production process, the device can cooperate with the pressing action of a pressing plate to automatically stabilize the mobile phone shell, and can cooperate with the return of the pressing plate to blow up the mobile phone shell, so that the mobile phone shell is prevented from being attached to a bearing seat too tightly, a user can take the mobile phone shell conveniently, meanwhile, automatic on-off of an electric heating piece can be achieved, the complexity of manual on-off of the electric heating piece is avoided, meanwhile, an arranged whistle can be matched with the pressing state of the pressing plate, and a worker is reminded of the pressing state of the pressing plate through sound changes generated by the whistle.

Description

technical field [0001] The invention belongs to the field of mobile phone shell production, and in particular relates to a production process of a mobile phone shell and a membrane pressing device thereof. Background technique [0002] The full name of a mobile phone is a mobile phone or a wireless phone. It is usually called a mobile phone. It was originally just a communication tool. It was commonly known as "Big Brother" in the early days. It is a portable phone terminal that can be used in a wide range. It is an important component that can protect the internal components in the mobile phone. [0003] At present, in order to improve the quality of the mobile phone casing, the mobile phone casing is generally made of aluminum. The production process of the aluminum mobile phone casing includes aluminum extrusion, drilling, polishing, painting, and film pressing. The film pressing is to press the film through the film pressing device. Closed to the surface of the mobile p...

Problems solved by technology

[0003] At present, in order to improve the quality of the mobile phone casing, the mobile phone casing is generally made of aluminum. The production process of the aluminum mobile phone casing includes aluminum extrusion, drilling, polishing, painting, and film pressing. The film pressing is to press the film through the film pressing device. Closed to the surface of the mobile phone case, the traditional membrane pressure device can only simply accept the mobile phone case, and cannot effectively stabilize the mobile phone case, so that the mobile phone case may shift during the film pressing process, affecting the effect of the film pressure
