Problems solved by technology

A release film (not shown) is pasted on one side of the protective film 10. After the adsorption fixture absorbs the protective film through the suction hole (the position of the suction hole corresponds to the position of the round hole 21), the release film will be torn off. The number of suction holes corresponding to the round hole 21 is small, and the suction volume is insufficient. When the release film is uncovered, the protective film 10 will be lifted together, resulting in air leakage from the jig, and it is difficult to separate the protective film from the release film. , affecting production efficiency and yield

Embodiment Construction

[0023] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0024] figure 2 It is a schematic structural view of the protective film 10 of the present invention, the protective film 10 is divided into a first area 31 and a second area 32, the second area 32 is arranged around the periphery of the first area 31, and the first area 31 and the second area There is a pre-break line 4 between the two regions 32 , and a release film (not shown) is attached to one side of the protective film 10 . The first region 31 and the second region 32 contain a plurality of connection points 41 at the pre-breaking line 4, the first region 31 and the second region 32 are connected through the connection points 41, wherein the width of the connection point The preferred choice is 0.05mm, the distance between adjacent connection points 41 is D, ...

Abstract

The invention provides a protective film-attaching method and a protective film. The protective film-attaching method includes the following steps: the protective film is provided and divided into a first area and a second area, the second area is arranged around the circumference of the first area, moreover, a prebroken line is arranged between the first area and the second area, and a release film is attached on the protective film; the protective film is placed on a jig, the jig is provided with suction holes which respectively correspond to the first area and the second area, and vacuumization is carried out via the suction holes, so that the protective film is attached on the jig; the release film is removed; an object to be attached is placed corresponding to the first area, and is attached on the first area; and the second area is removed along the prebroken line. Since the protective film is provided with the first area and the second area, the adsorption area is enlarged, moreover, the suction capacity of the protective film jig is increased, so that the protective film still can be completely sucked on the jig when the release film is removed, the phenomenon of air leakage is prevented, quality is guaranteed, productivity is increased, and the reject rate is decreased.

Description

technical field [0001] The invention relates to a protective film and a method for attaching the protective film, in particular to a protective film with a first region and a second region and a method for attaching the protective film. Background technique [0002] At present, the casings of 3C products (communication products, computer products, consumer electronics, etc.) are generally made of smooth engineering plastics, and the casings of electronic products are easily damaged during transportation and assembly of electronic products. The scratches caused by these scratches will affect the appearance and sales of consumer electronics products. Since these scratches are difficult to recover, electronic products with scratched shells may be sent for repairs and replaced with new shells, or therefore lowered This will undoubtedly increase the cost of the product or reduce the profit. [0003] In order to overcome the above disadvantages, usually after the casing of the el...
