After the release film 32 is separated from the protective film 31, the user can press the pressing portion 211 with uniform and regular strength at the outer side of the cover plate 21 by hand or tool, so that the protective film 31 is tightly attached to the screen of the electronic device 200 through the pressing portion 211, and the gas between the protective film 31 and the electronic device 200 can be pressed out, thereby ensuring the attaching tightness between the protective film 31 and the screen.

In a specific embodiment, referring to fig. 4 and 8, a positioning groove 15 is formed on an outer peripheral wall of the base 10, a positioning protrusion 221 is formed on an inner peripheral wall of the side plate 22, and the positioning protrusion 221 is engaged with the positioning groove 15 in a concave-convex manner, so as to firmly cover the upper cover 20 and the base 10 together. It is understood that, in other embodiments of the present application, the positioning protrusion 221 may be disposed on the outer peripheral wall of the base 10, and then the positioning groove 15 may be disposed on the inner peripheral wall of the side plate 22, and the positioning protrusion 221 and the positioning groove 15 are engaged in a concave-convex manner, which is not limited herein.

Referring to fig. 4 and 8, four positioning grooves 15 are formed in the outer peripheral wall of the base 10, the four positioning grooves 15 are respectively distributed on four corners of the base 10, correspondingly, four positioning protrusions 221 are also formed in the inner peripheral wall of the side plate 22, the four positioning protrusions 221 are respectively distributed on the four corners of the side plate 22, the four positioning protrusions 221 and the four positioning grooves 15 are in one-to-one concave-convex clamping, so that the base 10 and the upper cover 20 can be uniformly connected in the circumferential direction, the connection strength of the base is uniformly distributed, in addition, the upper cover 20 is integrally of a symmetrical structure due to the design, the installation direction of the upper cover 20 cannot be limited, and the operation by a user is facilitated. It is understood that, in other embodiments of the present application, both the number and the position of the positioning grooves 15 may be adjusted according to actual conditions, and both the number and the position of the positioning grooves 15 may also be adjusted according to actual conditions, which is not limited herein.

In a specific embodiment, referring to fig. 3, 8 and 9, a surface of the pressing portion 211 contacting the positioning film 33 is an arc surface, specifically, a distance from the arc surface to the positioning film 33 gradually increases from the middle to two ends along the length direction of the cover plate 21, and distances from the arc surface to the positioning film 33 are all equal along the width direction of the cover plate 21. After the release film 32 is torn off, the user can press the pressing portions 211 from the middle to both ends of the cover plate 21 along the length direction of the cover plate 21 on the outer side of the cover plate 21, so as to attach the protection film 31 to the screen of the electronic device 200. The utility model provides a portion 211 that compresses tightly passes through the setting of arcwall face for under the external pressure effect, portion 211 that compresses tightly is soft to the effort of location membrane 33 and protection film 31, does not scrape the power, and when tearing off from type membrane 32, portion 211 that compresses tightly is little to the extrusion force from type membrane 32, can not hinder the separation from type membrane 32. It is understood that in other embodiments of the present application, the surface of the pressing portion 211 contacting the positioning film 33 may also be a plane according to the actual design, and is not limited herein.

In a specific embodiment, referring to fig. 4, 5, 8 and 9, the base 10 and the cover 20 are both blister products. The plastic suction is a plastic processing technology, and the main principle is that after a flat plastic hard sheet is heated and softened, the plastic hard sheet is absorbed on the surface of a mould in vacuum, and the plastic hard sheet is formed after cooling. Specifically, the base 10 and the cover 20 may be formed by vacuum molding using polybutylene terephthalate (PET) or Polycarbonate (PC) material. This application is through all adopting plastic uptake goods with base 10 and upper cover 20, then can save the cost of moulding plastics of base 10 and upper cover 20, also can practice thrift the material cost and the cost of transportation of whole base 10 and upper cover 20, and simple structure, convenient to use, in addition, PET and PC are degradable material, make the contribution for the environmental protection. It is understood that in other embodiments of the present application, the base 10 may also be made of cardboard, and the cover 20 may also be made of cardboard, according to the actual design and specific requirements, so that the material cost of the base 10 and the cover 20 is simpler, more environmentally friendly and lower. In addition, in other embodiments of the present application, the base 10 and the upper cover 20 may also be an elongated plate-shaped block structure, and then the block structure is provided with a groove or a bump, which is not limited herein.

The application further provides a film attaching method, the film attaching jig 100 is used for attaching a film to the electronic device 200, and the film attaching method comprises the following steps:

the electronic device 200 is arranged in the limiting cavity 11, and one side of the electronic device 200 with the screen is arranged to protrude out of the limiting cavity 11;

positioning the membrane assembly 30 on the base 10 through the positioning structure 12, so that the release film 32 is abutted against the screen of the electronic device 200, and one end of the release film 32 extends out of the base 10 from the clearance 13; specifically, the four positioning holes 331 on the positioning film 33 are respectively sleeved on the four positioning posts 121 on the base 10, so that the film assembly 30 is integrally positioned on the base 10.

Covering the upper cover 20 on the base 10 to form a closed space 40; specifically, the cover plate 21 is covered on one side of the base 10 where the limiting cavity 11 is formed, the side plate 22 is covered on the outer side wall of the base 10, and the four positioning protrusions 221 and the four positioning grooves 15 are engaged in a concave-convex manner.

Pulling one end of the release film 32 to tear the release film 32 from the protective film 31 and taking out; specifically, one end of the extension 323 opposite to the folding line 321 is pulled downward to separate the attachment section 322 from the protective film 31.

Pressing the upper cover 20 to automatically exhaust the protective film 31 and make the protective film closely contact with the screen of the electronic device 200; specifically, the pressing portion 211 is pressed with a uniform force from the middle to both ends along the length direction of the upper cover 20, so that the protective film 31 is strongly adhered to the screen by the pressing portion 211.

The upper cover 20 is opened, the positioning film 33 is torn off, and the electronic apparatus 200 is taken out, thereby completing the film attaching work of the electronic apparatus 200.

According to the film pasting method, the film pasting jig 100 is used for pasting the film, so that the protective film 31 is always in the closed space 40 in the film pasting process, dust and static electricity in the air cannot be adsorbed, and the pasting tightness of the protective film 31 and a screen is improved. Meanwhile, after the release film 32 is torn off, the protective film 31 can be tightly attached to the screen only by pressing the upper cover 20, the positioning is quick, the operation is simple, the film attaching efficiency is improved, a user can attach the film by himself, and the film attaching interest is increased.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
