Camera protection membrane, die cutting production process and device

Abstract

The invention discloses a camera protection membrane, a die cutting production process and a device. The die cutting production process comprises the following steps: preparing raw materials accordingto pasting raw material components of the camera protection membrane, and sequentially mounting the prepared pasting raw materials on corresponding placing shafts, wherein a first PET (Polyethylene Terephthalate) membrane is used at the bottom, the side with an adhesive, of the first PET membrane faces upwards, the release surface of an optical membrane faces upwards, the adhesive side of a double-side adhesive faces downwards, and the release surface of a first release membrane faces downwards; carrying out primary pasting to form a first middle part, and withdrawing release paper of a double-side adhesive tape in the pasting process; carrying out primary die cutting after primary pasting, and forming an inner frame of a camera protection membrane product through primary die cutting; carrying out secondary pasting, secondary die cutting, third pasting, third die cutting, fourth pasting, fourth die cutting, fifth pasting, fifth die cutting and sixth molding in sequence, pulling up anouter frame rubber waste material, and slicing a fifth middle part, thereby finally forming a membrane carrier with a plurality of membrane products arranged in sequence. A manual combination procedure is avoided, assembling steps are reduced, the labor can be saved, and the pass percent can be increased.

Description

technical field

[0001] The invention relates to a camera protective film, a die-cutting production process and a device, and relates to the technical field of film processing. Background technique

[0002] With the promotion and application of electronic products, consumers have higher and higher requirements for the performance of electronic products, and have higher and higher requirements for appearance design, hardware design and software functions. At the same time, they have higher pursuit of cost performance of electronic products. . In particular, the mobile phone and notebook industries have been taking ultra-light and thin as the main development direction in recent years, and the structure and functions of electronic components are also developing in the direction of miniaturization and multi-function. The requirements for mobile phone cameras are also getting higher and higher. Before assembly, a protective film needs to be attached to avoid scratching the lens....
