Description

  The present invention relates to a protective film attaching jig used for attaching an adhesive surface of a protective film to an image display surface of an image display device.

  Conventionally, a protective film for protecting an image display surface of an image display device such as a mobile phone or a smartphone has been manufactured. Such a protective film is designed in accordance with the size of the image display surface of a mobile phone, a smartphone, or the like. Such a protective film is provided not only for protecting the image display surface but also for various purposes such as prevention of reflected light. In accordance with such purposes, various types of protective films corresponding to image display surfaces having specific dimensions have been manufactured. For this reason, a purchaser such as a mobile phone or a user such as a salesperson sticks a protective film according to the purpose of the purchaser on the image display surface. Patent Document 1 discloses an example of such a protective film.

  As described above, the protective film is manually attached to the image display surface. In order to apply the protective film without detaching from the display surface, the user needs to be patient and calm and perform the application work carefully. In other words, a high level of skill is required of the user. On the other hand, the pasting operation may still fail. In that case, the user once peels off the protective film from the image display surface and performs the pasting operation again. If such an operation is repeated, the adhesive strength of the protective film is lost and the protective film itself cannot be used. Then, the purchaser is forced to purchase a relatively expensive protective film.

  Then, the jig | tool for a protective film sticking which enables a user to affix a protective film correctly and easily with respect to an image display surface is proposed (for example, patent document 2).

Only the part 42 and the adhesive part 44 may be used. Moreover, although the nail | claw part 35 demonstrated as fixing a part of circumference | surroundings of a protective film, you may fix at least one of the circumference | surroundings of the film through-hole 122 and the film through-hole 124, and both fixed Also good.

The device attachment portion 30 is an attachment portion that is brought into a state where the image display device 200 is attached by fitting the frame portion 210 of the image display device 200 into a fitting portion formed by the step portion 32.
Even when the image display device 200 is attached to the device attachment portion 30, the step portion 32 is formed at a predetermined distance from the bottom surface of the recess 12 so that the image display device 200 does not contact the bottom surface of the recess 12. Yes. Further, the step portion 32 may be formed with a plurality of convex portions that contact the side surface of the image display device 200.

With reference to FIG.1 and FIG.5, the usage method of the jig | tool 10 for protective film sticking is demonstrated.
As shown in FIG. 1, first, the protective film 100 is held by the film holding unit 20 so that the protective surface 112 contacts the bottom surface of the recess 12. In other words, the film holding part 20 hold | maintains the to-be-held parts other than the adhesive surface 110 among the protective films 100 so that attachment or detachment is possible.
Specifically, the insertion rod 52 and the insertion rod 54 are fitted into the film through-hole 122 and the film through-hole 124, respectively, and the protective surface portion 142 and the protective surface portion 144 are pressed against the adhesive portions 42 and 44, thereby protecting them. The film 100 is held by the film holding unit 20. In other words, the film holding unit 20 holds the flat part 132 other than the film peripheral part 134 in the protective film 100, but the separator is attached to the adhesive surface protective sheet 150, the adhesive surface protective sheet 151, and the adhesive surface protective sheet 152. Are not touching.
At this time, since the adhesive surface 110 faces the opening side of the recess 12, the film peripheral portion 134 is separated from the bottom surface of the recess 12, and the flat portion 132 is substantially in close contact with the bottom surface of the recess 12.
Further, since the insertion rod 52 and the insertion rod 54 are fitted in the film through hole 122 and the film through hole 124, respectively, the protective film 100 is accurately positioned with respect to the apparatus mounting portion 30, and the film through hole 122 in the flat portion 132 is obtained. And the film through-hole 124 are stretched.
Further, the pressing through hole 60, the pressing through hole 61, and the pressing through hole 62 are blocked by the protective surface 112.
Even if the user directly touches the protective film 100 by hand so that the protective film 100 is held by the film holding unit 20, the separator is stuck on the adhesive surface 110 of the protective film 100. Does not adhere to dust and dirt.

Next, the adhesive surface protective sheet 150 at the center of the separator is peeled off from the protective film 100 to expose the central portion of the adhesive surface 110. At this time, the adhesive surface protective sheet 151 and the adhesive surface protective sheet 152 of the separator are not yet peeled from the protective film 100. The separator adhesive surface protective sheet 151 and the adhesive surface protective sheet 152 are peeled off after the image display device 200 described later is removed from the protective film affixing jig 10.
For this, only the adhesive surface protective sheet 150 of the central separator is peeled off, and the position is adjusted and attached using a protective film attaching jig 10 to be described later, and then the image display device 200 is attached to the protective film attaching jig. After removing from the tool 10, the left and right adhesive surface protection sheets 151 and the adhesive surface protection sheet 152 are peeled in order to make it difficult for dust to adhere to the adhesive surface of the protective film 100 and protect at once. It can be made easier to paste than the film 100 is bonded to the entire surface.
Thereby, since the protective film 100 is hold | maintained by the film holding | maintenance part 20, when peeling the adhesive surface protection sheet 150 of a separator, there is no possibility that the protective film 100 may peel from the film holding | maintenance part 20, or may shift | deviate. Furthermore, since the adhesive surface protective sheet 151 and the adhesive surface protective sheet 152 cover the adhesive surface 110, the adhesive surface protective sheet 150 can be peeled off while pressing the adhesive surface protective sheet 151 and the adhesive surface protective sheet 152.

Next, the image display device 200 is attached to the device attachment portion 30 so as to face the adhesive surface 110 of the protective film 100 held by the film holding portion 20. As a result, the image display surface 220 and the adhesive surface 110 face each other, and a predetermined space is formed between the image display surface 220 and the adhesive surface 110, so that the image display device 200 is attached to the device attachment portion 30. At this time, the image display surface 220 does not stick to the adhesive surface 110 by mistake.
Further, when the pressing through hole 60 is viewed in the direction in which the image display surface 220 faces the adhesive surface 110 in a state where the protective film 100 is held by the film holding unit 20, the pressing through hole 60 is not bonded to the adhesive surface protective sheet 150. Is in.

  Next, the frame portion 210 of the image display device 200 is fitted into the fitting portion formed by the step portion 32 so that the image display surface 220 faces the adhesive surface 110. As a result, the image display device 200 is attached to the device mounting portion in a state where the image display device 200 is positioned with respect to the protective film 100 and a predetermined distance is placed between the image display surface 220 and the adhesive surface 110. 30.

Next, as shown in FIG. 5, the protective film sticking jig 10 is turned upside down so that the protective film 100 and the image display device 200 are not detached from the protective film sticking jig 10.
Then, the protective surface 112 is pressed with the user's finger f inserted from the pressing through hole 60 so that the adhesive surface 110 adheres to the image display surface 220. At this time, the finger f may be slid from the center of the pressing through hole 60 toward both ends in the longitudinal direction.
At this time, when the finger f slides in the vicinity of the adhesive portion 42, the adhesive portion 44, the insertion rod 52, and the insertion rod 54, the protective film 100 around the insertion rods 52 and 54 is strongly pressed against the image display surface 220. The protective surface portion 142 and the protective surface portion 144 are peeled off from the adhesive portion 42 and the adhesive portion 44, respectively, and the insertion rod 52 and the insertion rod 54 may come out of the film through hole 122 and the film through hole 124, respectively. Since the center of the film 100 is already attached to the image display surface 220, the protective film 100 is not displaced from the image display surface 220 or peeled off from the image display surface 220.
Then, the adhesive surface protective sheet 151 and the adhesive surface protective sheet 152 of the separator are peeled off, and both ends of the protective film 100 are attached to the image display surface 220. At this time, since the center of the protective film 100 is already attached to the image display surface 220, the protective film 100 is not displaced from the image display surface 220 or peeled off from the image display surface 220.
Then, the image display device 200 is removed from the protective film attaching jig 10.
Thereafter, the separator adhesive surface protective sheet 151 and the adhesive surface protective sheet 152 are peeled off from the image display device 200.
