In the case of extreme glue dispensing width, especially on some 3D spatial surfaces, it will become very difficult to achieve uniform glue dispensing. In addition, during the application process, the glue often breaks due to abnormal operation of the glue dispenser, which leads to a series of problems in the combination of components due to the loose sealing of the glue.

[0026] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] In the accompanying drawings, the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limitations on the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present disclosure. The embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings.

[0028] With the development of mobile terminal technology, full-screen mobile terminals with high screen-to-body ratio have become an indispensable part of people's daily life. However, as the full-screen screen-to-body ratio of mobile terminals becomes higher and higher, the internal space of mobile terminals becomes smaller and smaller, and as a result, the operating space left for the glue dispenser to perform glue dispensing is getting smaller and smaller. It is understandable that in the case of extreme glue dispensing width, especially on some bonding surfaces with special spaces, it will become very difficult to achieve uniform glue dispensing. In addition, during the application process, there are often situations such as glue breaking due to abnormal operation of the glue dispenser. Therefore, in the process of dispensing the mobile terminal, providing a solution that does not require an operating space for the glue dispenser to perform glue dispensing, or does not require the use of a glue dispenser, has become the focus of current attention.

[0029] The disclosed embodiments provide a method for preparing a glue sheet, a glue sheet, and a method for bonding components. The method for preparing a glue sheet comprises forming a glue layer on a first plastic film, covering a second plastic film on the glue layer, and molding the second plastic film to form a plurality of independent protruding monomers containing glue, thereby obtaining a glue sheet. Since the plurality of protruding monomers of the glue sheet can be broken under the pressure of an external force, the glue can overflow. Therefore, when the glue sheet is placed between the components to be bonded, and the components to be bonded are pressed by an external force so that the glue of the glue sheet overflows and bonds the components, the uniform glue dispensing process of the components to be bonded can be completed quickly and conveniently, thereby realizing the bonding process of the components to be bonded, and improving the bonding firmness between the components to be bonded.

[0030] A first aspect of an embodiment of the present disclosure provides a method for preparing a glue sheet.

[0031] Figure 1 The figure is a flow chart of a method for preparing a glue sheet according to an exemplary embodiment.

[0032] In an exemplary embodiment of the present disclosure, Figure 1 As shown, the method for preparing the glue sheet includes steps S11 to S13, and each step will be introduced below.

[0033] In step S11, a first plastic film is disposed on the bottom plate, and glue is evenly coated on the first plastic film to form a glue layer.

[0034] In one embodiment, a first plastic film can be evenly attached to a flat bottom plate or operating table, and glue can be evenly coated on the first plastic film to form a glue layer. In one embodiment, in order to ensure that the glue layer coated on the first plastic film is sufficient to adhere to the parts to be bonded, the formed glue layer can be set to a glue layer with a certain thickness. That is, a certain thickness of glue can be evenly coated on the first plastic film. During the application process, the thickness of the coated glue can be adjusted according to the actual situation so that the formed glue layer is sufficient to firmly adhere to the parts to be bonded. In the embodiments disclosed herein, the thickness of the set glue layer is not specifically limited.

[0035] In step S12, a second plastic film is covered on the glue layer.

[0036] In one embodiment, the second plastic film layer is covered on the glue layer to form an initial glue sheet, wherein the initial glue sheet can be understood as a glue sheet that has not yet been formed, and the initial glue sheet is composed of the first plastic film, the glue layer and the second plastic film from bottom to top.

[0037] In step S13, the second plastic film is compression molded to form a plurality of independent protruding monomers containing glue formed by the second plastic film on the first plastic film, thereby obtaining a glue sheet.

[0038] In one embodiment, the second plastic film is compression molded by a molding machine or a mold to form a plurality of independent protruding monomers containing glue formed by the second plastic film on the first plastic film, thereby obtaining a glue sheet.

[0039] During the application process, the glue sheet is placed between the parts to be bonded, and the parts to be bonded are pressed by external force, so that the glue contained in the protruding monomer can overflow and bond the parts. In one embodiment, in order to ensure that the protruding monomer is easy to break under the action of external force pressing, the first plastic film and the second plastic film can have a lower density. In one example, the first plastic film and the second plastic film can be a material with a density less than or equal to 0.96g / cm 3 It should be noted that the polyethylene film has a certain toughness and will not break without being pressed by a sufficiently large external force. In one example, during the bonding process of the parts to be bonded, a glue sheet can be placed between the parts to be bonded, and under the pressure of an external force greater than 5MPa, the protruding monomers of the polyethylene film material are broken, and then the glue overflows and the parts are bonded.

[0040] In the application process, in order to ensure that the protruding monomers are easily broken under the action of external force pressing and then overflowing the glue, when the glue sheet is pressed by external force, it should be ensured that the external force acting on each protruding monomer is concentrated. Therefore, in one embodiment, the shape of the protruding monomer can be set to be hemispherical. In the application process, the protruding monomer can be made by molding the second plastic fat film using a mold having a hemispherical shape.

[0041] When the glue sheet is pressed by external force, the radius of the protrusion monomer can be limited to ensure that the external force acting on each protrusion monomer is concentrated. In another embodiment, the radius of the protrusion monomer can be greater than or equal to 0.1 mm.

[0042] It is understandable that, on the one hand, in order to ensure that the glue coated on the first plastic film does not flow in all directions like a liquid, and thus cannot form a glue layer. On the other hand, in order to ensure that the glue can easily overflow from the protruding monomer, the glue needs to have a certain fluidity. Therefore, in one embodiment, the glue can be a molten glue.

[0043] In the preparation method of the glue sheet provided by the present disclosure, a glue layer is formed on a first plastic film, and a second plastic film is covered on the glue layer, and the second plastic film is molded to form a plurality of independent protruding monomers containing glue, thereby obtaining a glue sheet. Since the plurality of protruding monomers of the glue sheet can be broken under the pressure of external force, and then the glue overflows. Therefore, when the glue sheet is placed between the parts to be bonded, and the parts to be bonded are pressed by external force, so that the glue of the glue sheet overflows and bonds the parts, the uniform glue dispensing process of the parts to be bonded can be completed quickly and conveniently, thereby realizing the bonding process of the parts to be bonded, and improving the bonding firmness between the parts to be bonded.

[0044] The present disclosure will illustrate the process of another method for preparing a glue sheet through the following embodiments.

[0045] Figure 2 The present invention is a flow chart of another method for preparing a glue sheet according to an exemplary embodiment.

[0046] In an exemplary embodiment of the present disclosure, Figure 2 As shown, the glue sheet preparation method includes steps S21 to S24, wherein steps S21 to S23 are the same as steps S11 to S13 described above, and the specific steps and beneficial effects thereof are referred to the above description, which will not be repeated in the present embodiment. Step S24 will be described in detail below.

[0047] In step S24, a double-sided adhesive is adhered to the side of the first plastic film of the adhesive sheet facing away from the adhesive, and a release paper is covered on the side of the double-sided adhesive not adhered to the first plastic film.

[0048] In one embodiment, double-sided tape can be adhered to the side of the first plastic film of the glue sheet facing away from the glue, so that when the glue sheet is used for bonding between the parts to be bonded, the glue sheet can be fixed on any one of the parts to be bonded in advance to facilitate the bonding of the parts to be bonded.

[0049] In another embodiment, the side of the double-sided adhesive tape that is not bonded to the first plastic film may be covered with release paper. During application, the release paper bonded to the double-sided adhesive tape may be peeled off first, and the double-sided adhesive tape may be bonded to the component to be bonded, so as to facilitate bonding of the component to be bonded.

[0050] In another embodiment, a double-sided adhesive tape covered with release paper can be directly bonded to the side of the first plastic film of the glue sheet facing away from the glue. It is understandable that the release paper covers the side of the double-sided adhesive tape that is not bonded to the first plastic film. During the application process, the release paper bonded to the double-sided adhesive tape can be peeled off first, and the double-sided adhesive tape can be bonded to the component to be bonded, so as to facilitate the bonding process of the component to be bonded.

[0051] Figure 3 It is a schematic front view structure diagram of a glue sheet manufactured based on a glue sheet preparation method according to an exemplary embodiment. Figure 4 The figure is a schematic side view of a glue sheet manufactured based on a method for preparing a glue sheet according to an exemplary embodiment.

[0052] The following will be combined Figure 3 and Figure 4 The structure of the glue sheet manufactured based on the glue sheet preparation method is described.

[0053] In an exemplary embodiment of the present disclosure, according to Figure 3 It can be seen that in the glue sheet 100 prepared based on the glue sheet preparation method, after the second plastic film is subjected to compression molding, a plurality of independent protruding monomers 101 formed by the second plastic film can be formed on the first plastic film. Among them, the protruding monomer 101 contains glue, and the shape of the protruding monomer 101 can be hemispherical. During the application process, the glue sheet 100 is placed between the parts to be bonded, and the parts to be bonded are pressed by external force, so that the glue in the protruding monomer 101 overflows and bonds the parts, thereby ensuring that the glue dispensing process of the parts to be bonded can be achieved without using a glue dispensing machine.

[0054] according to Figure 4It can be seen that in another embodiment, after the second plastic film 203 is subjected to compression molding, a plurality of independent protrusion monomers formed by the second plastic film 203 can be formed on the first plastic film 201. The protrusion monomer contains glue 202. It can be understood that the formed plurality of independent protrusion monomers can constitute the glue sheet 200.

[0055] As the screen-to-body ratio of full-screen mobile terminals increases, the internal space of mobile terminals decreases, which results in less and less operating space for glue dispensing during the bonding of the parts to be bonded. In one embodiment, the glue sheet 200 can be placed between the parts to be bonded, and the parts to be bonded are pressed by external force, so that the glue in the glue sheet 200 overflows and bonds the parts, ensuring that in the small operating space scenario of glue dispensing, the parts to be bonded can be quickly and conveniently evenly glued, thereby achieving the bonding of the parts to be bonded and improving the bonding firmness between the parts to be bonded.

[0056] By using the glue sheet described in the embodiment of the present disclosure, it can be ensured that the bonding process of the parts to be bonded can be achieved without using a glue dispenser.

[0057] The present disclosure will illustrate the process of another method for preparing a glue sheet through the following embodiments.

[0058] Figure 5 is a flow chart of yet another method for preparing a glue sheet according to an exemplary embodiment.

[0059] In an exemplary embodiment of the present disclosure, Figure 5 As shown, the glue sheet preparation method may include steps S31 to S34, wherein steps S31 to S33 are the same as steps S11 to S13 described above, and the specific steps and beneficial effects thereof are referred to the above description, which will not be repeated in the present embodiment. Step S34 will be described in detail below.

[0060] In step S34, the glue sheet is die-cut based on a preset shape.

[0061] In one example, the glue sheet can be die-cut based on a drawing with a preset shape. Since the bonding surface between the parts to be bonded can include a variety of shapes, when the parts to be bonded are bonded based on the glue sheet, the shape of the glue sheet needs to match the bonding surface. In one embodiment, a drawing with a preset shape can be designed according to the shape of the bonding surface between the parts to be bonded. Among them, the preset shape of the drawing can be adjusted according to actual conditions, and in the present disclosure, the preset shape of the drawing is not specifically limited. In one embodiment of the present disclosure, the preset shape of the drawing can match the shape of the bonding surface.

[0062] Furthermore, the glue sheet can be die-cut based on the drawing that matches the shape of the surface to be bonded, so that the shape of the glue sheet matches the surface to be bonded of the component to be bonded, ensuring that the glue sheet can effectively bond the component to be bonded. It should be noted that in order to ensure that the protruding monomers will not be cut and cause the glue to flow out during the die-cutting process of the glue sheet, the drawing can be preset based on the position of each protruding monomer in the glue sheet and the shape of the surface to be bonded. In the process of die-cutting the glue sheet based on the drawing, it can be ensured that the glue sheet matches the shape of the surface to be bonded, and the glue sheet can also be cut along the edge of the protruding monomer, thereby ensuring that the protruding monomer will not be cut.

[0063] In another embodiment, in the process of making the glue sheet, the first plastic film and the second plastic film may be die-cut based on the drawing matching the shape of the surface to be bonded, and then a glue layer may be coated on the die-cut first plastic film, and the die-cut second plastic film may be covered on the glue layer and molded. This allows the shape of the finished glue sheet to match the surface to be bonded of the component to be bonded, ensuring that the glue sheet effectively bonds to the component to be bonded.

[0064] In another embodiment, the method for preparing the glue sheet may further include the steps S21 to S24 and step S34 described above. Since the specific steps and beneficial effects of steps S21 to S24 and step S34 have been described in detail above, they will not be repeated in the embodiments of the present disclosure. It is understood that the above embodiments may be implemented separately or in combination, and the specific implementation of the method for preparing the glue sheet is not limited in the present disclosure.

[0065] Based on the same inventive concept, a second aspect of the embodiments of the present disclosure provides a glue sheet.

[0066] Figure 6 The figure is a schematic diagram of the structure of a glue sheet according to an exemplary embodiment.

[0067] In an exemplary embodiment of the present disclosure, Figure 6 As shown, the glue sheet 300 includes a first plastic film 301 and a plurality of independent protruding monomers 302. The first plastic film 301 and the plurality of independent protruding monomers 302 will be introduced separately below.

[0068] In one embodiment, the first plastic film 301 may be a plastic film with a low density. For example, the first plastic film 301 may be a polyethylene film with a low density, wherein the density of the polyethylene film may be less than or equal to 0.96 g / cm 3 .

[0069] In yet another embodiment, glue 303 may be contained in a plurality of independent protruding monomers 302 , and the protruding monomers 302 are formed on the first plastic film 301 by the second plastic film 3021 .

[0070] During the application process, the glue sheet 300 is placed between the parts to be bonded, and the parts to be bonded are pressed by external force, so that the glue 303 contained in the protruding monomer 302 can overflow and bond the parts. In one embodiment, in order to ensure that the protruding monomer 302 is easy to break under the action of external force pressing, the second plastic film 3021 can also be set to be a plastic film with a lower density. In one example, the second plastic film 3021 can be a plastic film with a low density. For example, the second plastic film 3021 can be a polyethylene film with a low density, wherein the density of the polyethylene film can be less than or equal to 0.96g / cm 3 .

[0071] It is understandable that when the glue sheet 300 is used to bond the components to be bonded, the glue sheet 300 can be fixed on any one of the components to be bonded in advance to facilitate the bonding of the components to be bonded. In one embodiment, the glue sheet 300 can also include double-sided tape 304. The double-sided tape can be bonded to the side of the first plastic film 301 that is away from the glue 303.

[0072] In one example, a plurality of independent protrusion monomers 302 may be arranged uniformly to form the glue sheet 300. A plurality of independent protrusion monomers 302 may be arranged non-uniformly to form the glue sheet 300. A plurality of independent protrusion monomers 302 may also be arranged in a dot matrix to form the glue sheet 300. In the present disclosure, the arrangement of the plurality of independent protrusion monomers 302 to form the glue sheet 300 is not specifically limited.

[0073] In another embodiment, the glue sheet 300 may further include release paper. The release paper covers the side of the double-sided adhesive tape 304 that is not bonded to the first plastic film 301. During the application process, the release paper bonded to the double-sided adhesive tape 304 may be peeled off first, and the double-sided adhesive tape 304 may be bonded to the component to be bonded, so as to facilitate the bonding process of the component to be bonded.

[0074] The glue sheet 300 provided in the embodiment of the present disclosure has a plurality of protruding monomers 302 which can be broken under the pressure of an external force, thereby overflowing the glue 303. Therefore, when the glue sheet 300 is placed between the parts to be bonded, and the parts to be bonded are pressed by an external force, so that the glue 303 of the glue sheet 300 overflows and bonds the parts, the uniform glue dispensing process of the parts to be bonded can be completed quickly and conveniently, thereby achieving the bonding process of the parts to be bonded, and improving the bonding firmness between the parts to be bonded.

[0075] Figure 7 It is a schematic diagram of an enlarged structure of a local structure of a glue sheet according to an exemplary embodiment.

[0076] This disclosure will combine Figure 7 , the glue sheet made based on the glue sheet preparation method is described.

[0077] In one embodiment of the present disclosure, Figure 7 As shown, the glue sheet 400 includes a first plastic film 401 and a plurality of independent protruding monomers 402 containing glue 403. The protruding monomers 402 are formed on the first plastic film 401 by a second plastic film 4021.

[0078] In order to ensure that the protruding monomer 402 is easily broken under the action of external force pressing, and then the glue 403 overflows, when the glue sheet 400 is pressed by external force, it should be ensured that the external force acting on each protruding monomer 402 is concentrated. Therefore, in one embodiment, the shape of the protruding monomer 402 can be set to be hemispherical. In the application process, the protruding monomer 402 can be made by molding the second plastic film 4021 using a mold with a hemispherical shape.

[0079] In another embodiment, when the glue sheet 400 is pressed by external force, the external force acting on each protrusion unit 402 can be concentrated by limiting the radius of the protrusion unit 402. In one example, the radius of the protrusion unit 402 can be greater than or equal to 0.1 mm.

[0080] In another embodiment, the glue sheet 400 may further include a double-sided adhesive tape 404 and a release paper, wherein the double-sided adhesive tape 404 is bonded to the side of the first plastic film 401 facing away from the glue 403 ; and the release paper covers the side of the double-sided adhesive tape 404 not bonded to the first plastic film 401 .

[0081] Based on the same inventive concept, a third aspect of the embodiments of the present disclosure provides a component bonding method.

[0082] The component bonding method can be applied to a glue sheet to perform bonding treatment on the components to be bonded. The glue sheet can be the glue sheet described in the second aspect of the embodiment of the present disclosure. The glue sheet can include a first plastic film, and a plurality of independent protruding monomers containing glue formed by a second plastic film on the first plastic film.

[0083] Figure 8 The figure is a flow chart of a component bonding method according to an exemplary embodiment.

[0084] In an exemplary embodiment of the present disclosure, Figure 8 As shown, the component bonding method includes step S41 and step S42, and each step will be introduced below.

[0085] In step S41, a glue sheet is placed between the parts to be bonded.

[0086] Fig. 9 It is a schematic diagram showing a component bonding method shown in an embodiment of the present disclosure according to an exemplary embodiment.

[0087] In one embodiment, if Fig. 9 As shown, for the convenience of description, in this embodiment, the upper cover plate 501 and the lower cover plate 502 are taken as the components to be bonded as an example to describe the entire process of the component bonding method.

[0088] During application, a glue sheet 503 may be placed between the upper cover plate 501 and the lower cover plate 502 .

[0089] In step S42, the parts to be bonded are pressed together by external force to rupture the second plastic film of the protruding monomer, and the glue contained in the protruding monomer overflows to bond the parts.

[0090] In one embodiment, after placing the glue sheet 503 between the upper cover plate 501 and the lower cover plate 502, the upper cover plate 501 or the lower cover plate 502 can be pressed together by external force to rupture the second plastic film of the protruding monomer of the glue sheet 503 placed between the upper cover plate 501 or the lower cover plate 502, and overflow the glue contained in the protruding monomer, thereby bonding the upper cover plate 501 and the lower cover plate 502.

[0091] Through this embodiment, the glue sheet 503 is placed between the parts to be bonded (the upper cover plate 501 and the lower cover plate 502), and the parts to be bonded are pressed by external force, for example, the upper cover plate 501 is pressed along the direction of the external force F, so that the glue in the glue sheet 503 overflows and bonds the parts, thereby ensuring that the glue dispensing process of the upper cover plate 501 and the lower cover plate 502 can be achieved without using a glue dispensing machine.

[0092] It is understandable that the component bonding method described in the present disclosure can be applied to the bonding process between components to be bonded in a mobile terminal, such as the bonding process between the upper cover plate 501 and the lower cover plate 502. The component bonding method described in the present disclosure can also be applied to the bonding process between components to be bonded in other electronic products. In the present disclosure, the application scope of the component bonding method is not specifically limited.

[0093] The present disclosure will illustrate the process of another component bonding method through the following embodiments.

[0094] In an exemplary embodiment of the present disclosure, the glue sheet further includes a double-sided adhesive bonded to the side of the first plastic film of the glue sheet facing away from the glue, and a release paper covering the side of the double-sided adhesive not bonded to the first plastic film. The placement of the glue sheet between the components to be bonded can be achieved in the following manner.

[0095] The release paper is peeled off, and the side of the double-sided adhesive not bonded to the first plastic film is bonded to the bonding surface of one of the components to be bonded.

[0096] When the glue sheet is used to bond the parts to be bonded, the glue sheet can be fixed on any one of the parts to be bonded in advance to facilitate the bonding of the parts to be bonded. In one embodiment, the glue sheet can also include double-sided tape. The double-sided tape can be bonded to the side of the first plastic film that is away from the glue.

[0097] In another embodiment, the glue sheet may further include release paper. The release paper covers the side of the double-sided adhesive tape that is not bonded to the first plastic film. During application, the release paper bonded to the double-sided adhesive tape may be peeled off first, and the double-sided adhesive tape may be bonded to the component to be bonded, so as to facilitate bonding of the component to be bonded.

[0098] According to the above description, in the component bonding method, since the multiple protruding monomers of the glue sheet can be broken under the pressure of external force, the glue will overflow. Therefore, when the glue sheet is placed between the components to be bonded, and the components to be bonded are pressed by external force, the glue of the glue sheet overflows and bonds the components, the uniform dispensing process of the components to be bonded can be completed quickly and conveniently, thereby achieving the bonding process of the components to be bonded and improving the bonding firmness between the components to be bonded. Through the glue sheet described in the embodiment of the present disclosure, it can be ensured that the bonding process of the components to be bonded can be achieved without using a dispensing machine.

[0099] It is to be understood that in the present disclosure, "plurality" refers to two or more than two, and other quantifiers are similar. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. The singular forms "a", "the" and "the" are also intended to include plural forms, unless the context clearly indicates other meanings.

[0100] It is further understood that the terms "first", "second", etc. are used to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other, and do not indicate a specific order or degree of importance. In fact, the expressions "first", "second", etc. can be used interchangeably. For example, without departing from the scope of the present disclosure, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information.

[0101] It is further understood that, although the operations are described in a specific order in the drawings in the embodiments of the present disclosure, it should not be understood as requiring the operations to be performed in the specific order shown or in a serial order, or requiring the execution of all the operations shown to obtain the desired results. In certain environments, multitasking and parallel processing may be advantageous.

[0102] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art that are not disclosed in the present disclosure. The specification and examples are intended to be exemplary only, and the true scope and spirit of the present disclosure are indicated by the following claims.

[0103] It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
