Protective film used in mobile phone product assembly process, and production technology and production device thereof

Abstract

The invention relates to a protective film used in a mobile phone product assembly process, and a production technology and device thereof. The protective film comprises release paper and a protective film main film; the middle parts of two ends of the protective film main film are provided with a first notch and a second notch respectively; the protective film main film and the upper parts of the peripheries of the two notches are attached with a first covering film and a second covering film respectively; one side of the first covering film and one side of the second covering film are respectively provided with a first extending part and a second extending part which extend outwardly; the lower surfaces of the first extending part and the second extending part are attached with a first isolating film and a second isolating film respectively. The production device and the production technology can be operated to be performed only by one person; the production device adopts a circular knife die cutting way, and has the advantages of automatic operation, fast running speed and high production efficiency; the protective film in the production process is convenient to use, the notches and the notch covering films are provided, and the protective film can be simultaneously suitable for protection requirements of multiple components and parts in the assembly process so as to bring assembly workers convenience.

Description

Technical field: [0001] The invention relates to the technical field of mobile phone assembly parts, in particular to a protective film used in the assembly process of mobile phone products, its production process and production equipment. Background technique: [0002] At present, the design of mobile phones is becoming more and more exquisite and high-end, and the requirements for the assembly and processing of mobile phone parts are also getting higher and higher. During the assembly process of mobile phone parts, especially the assembly process of mobile phone screens, buttons, cameras and other parts, it is necessary to prevent screen , buttons, camera, etc. are touched and polluted, so it is necessary to use a protective film called an "in-process protective film" to protect them. At present, the protective film in this type of process is too simple. For example, it only consists of a main protective film and a release paper, which cannot meet the diverse needs of use ...

AI Technical Summary

Problems solved by technology

At present, the protective film in this type of process is too simple. For example, it only consists of a main protective film and a release paper, which cannot meet the diverse needs of use and is inconvenient to peel off and use, which affects the efficiency of workers’ assembly; moreover, the production of the protective film itself The process automation is low, requiring multiple people to operate and multiple devices to work at the same time. The production efficiency is low, the labor cost is high, and the material travel is long, the probability of contamination is high, and the product quality is affected.
