Description

Technical Field

[0001] The present invention relates to the technical field of tempered films, and in particular to a tempered film with a fixed bonding substrate at the edge of a glass sheet and a manufacturing process thereof. Background Art

[0002] Tempered film is mainly made of specially treated glass material. This kind of glass has been tempered by high temperature, which greatly improves its hardness compared with ordinary glass. It can usually reach a Mohs hardness of about 9H, which means that it can effectively resist scratches on the screen by sharp objects such as keys and coins in daily life, providing a reliable first line of defense for the device screen. In terms of function, the core role of tempered film is undoubtedly to protect the screen. It can not only prevent the screen from being scratched, but also disperse the impact force when mobile phones, tablets and other devices are accidentally dropped, greatly reducing the risk of screen breakage due to its good toughness and strength. Moreover, high-quality tempered film also has excellent light transmittance, which can ensure that the content displayed on the screen is clearly visible, and restore the original color and picture quality of the screen to the maximum extent, so that users can enjoy the visual experience of the device without worrying about screen damage.

[0003] However, with the continuous updating of mobile phones, some existing mobile phone models will be configured with a structure with curved screens and flat screens. Curved screens are widely used in many high-end electronic devices with their unique appearance design and excellent visual effects. However, finding suitable tempered films for them faces many challenges.

[0004] First, the curvature of the curved screen greatly increases the difficulty of attaching the tempered film. Unlike a flat screen, the curved part requires the tempered film to accurately conform to its curvature for attachment. Otherwise, it is very easy for the edges to warp and the fit to be loose. This not only affects the overall appearance of the device, but is also likely to cause dust, water vapor and other impurities to enter from the warped part, causing potential damage to the screen. Secondly, during the bonding process, due to the special shape of the curved screen, bubbles are easily generated between the tempered film and the screen. Even if extremely meticulous operations are taken during film application, it is still difficult to completely avoid the appearance of bubbles. These bubbles will interfere with the visual effect of the screen, causing the display to be partially blurred or deformed, seriously affecting the user experience.

[0005] Furthermore, in order to achieve a better fitting effect, some tempered films will adopt special glue or glue layer design, but this may cause new problems, such as glue residue polluting the screen, or being difficult to clean up when replacing the tempered film later. In addition, there are also some tempered films that will be mounted on the screen by only fitting the edges. However, since this fitting method uses glue, its fitting firmness is greatly reduced. In the case of strong impacts such as the phone falling or sliding the screen with a large force, the tempered film will directly detach from the phone screen, and its sticking firmness will be further reduced when re-fitting.

[0006] In view of this, it is necessary to propose an improved technical solution to solve the above problems. Summary of the Invention

[0007] The present invention aims to provide a technical solution to solve the above problems in order to overcome the above deficiencies.

[0014] Preferably, the tempered glass sheet further includes a blue light blocking layer, and the blue light blocking layer is disposed between the explosion-proof film layer and the glass layer.

[0015] Preferably, the left and right sides of the tempered glass sheet are respectively curved surfaces, and the screen fitting film and the C-shaped metal frame are adapted to the curved surface structure of the tempered glass sheet.

[0017] A manufacturing process of a tempered film with a fixed fitting matrix on the edge of a glass sheet, which is used to manufacture a tempered film with a fixed fitting matrix on the edge of a glass sheet as described above and is applied to a curved screen, includes the following steps: Step 1, manufacture the screen fitting film. Prepare PET film material, OCA film material, adhesive film material and release film material. Attach the OCA film material and the adhesive film material to the release film material respectively through a laminating machine, and then cut the OCA film material and the adhesive film material on the release film material into the corresponding size and shape of the OCA glue layer and the adhesive strip through a film cutting machine. Then cut the PET film material into a PET layer through a film cutting machine. Finally, position and attach the OCA glue layer and the adhesive strip to the PET layer respectively through a film pasting machine to make the screen fitting film for standby; Step 2, manufacture the C-shaped metal frame. Make a corresponding mold according to the size structure of the C-shaped metal frame. Put the metal material for manufacturing the C-shaped metal frame into the mold, and form the structure of the C-shaped metal frame through a stamping machine. Then put it into a dispensing machine through a positioning jig, and coat the pressing edge material at the lower end of the fixed edge through the dispensing machine; Step 3: Manufacture the tempered glass sheet. Prepare the glass raw material, cut the glass raw material into a size suitable for processing, precisely process the glass sheet through a CNC numerical control machine tool to make the glass sheet into a preset size and have a stepped edge and a slot. Immediately afterwards, remove the defects and scratches on the glass surface through a polishing process, then remove the dirt and impurities on the glass surface through a cleaning agent. Then, put the glass into a hot bending machine and make its left and right sides bend into the required curved shape through heating and pressurization. Next, put the glass into a tempering furnace for high-temperature treatment to form compressive stress on its surface. Finally, coat a fingerprint-proof oil film on the glass surface and attach an explosion-proof film layer on the back of the glass. If necessary, attach an anti-peeping layer or an anti-blue light layer between the glass and the explosion-proof film layer; Step 4: Manufacture the edge seal strip. Prepare the double-sided adhesive strip material, cut out a suitable double-sided adhesive strip according to the size of the rear part of the tempered glass sheet, and paste and fix it at the corresponding position of the tempered glass sheet; then attach a release strip to the double-sided adhesive strip and fold the release strip so that the extended end of the release strip is located behind the tempered glass sheet; Step 5: Assemble the film. Before leaving the factory, first bond and fix the U-shaped metal frame and the screen bonding film through a bonding strip; when in use, first tear off the release film on the back of the screen bonding film, and then mount the screen bonding film on the screen of the product to be film-applied. During the film-applying process, a corresponding film applicator can be used to complete the film-applying operation. After pasting, insert the tempered glass sheet between the U-shaped metal frame and the screen bonding film along the rear of the U-shaped metal frame. During the insertion process, ensure that the moving direction of the tempered glass sheet is directly facing the insertion direction, and a corresponding auxiliary tool can be used to complete the insertion operation of the tempered glass sheet. Finally, when the tempered glass sheet completely enters between the U-shaped metal frame and the screen bonding film, tear off the release strip, and then attach the double-sided adhesive strip to the screen bonding film through a roller, thereby completing the assembly and film-applying operation of the finished tempered film.

[0018] A manufacturing process for a tempered film with a fixed fitting base on the edge of a glass sheet, used to manufacture the above-mentioned tempered film with a fixed fitting base on the edge of a glass sheet, and applied to a straight screen, including the following steps: Step 1: Manufacture the screen bonding film. Prepare the PET film material, OCA film material, bonding film material and release film material. Attach the OCA film material and the bonding film material to the release film material respectively through a laminating machine, and then cut the OCA film material and the bonding film material on the release film material into the corresponding size and shape of the OCA adhesive layer and the bonding strip through a film cutting machine. Then, cut the PET film material into a PET layer through a film cutting machine. Finally, position and attach the OCA adhesive layer and the bonding strip to the PET layer respectively through a film pasting machine to make the screen bonding film for standby; Step 2: Manufacture a U-shaped metal frame. Make a corresponding mold according to the size and structure of the U-shaped metal frame. Place the metal material for manufacturing the U-shaped metal frame into the mold, and form the structure of the U-shaped metal frame through stamping by a stamping machine. Then, place it on a dispensing machine through a positioning jig, and apply the pressing edge material to the lower end of the fixed edge by the dispensing machine. Step 3: Manufacture a tempered glass sheet. Prepare glass raw materials, cut the glass raw materials into suitable sizes for processing, and precisely process the glass sheet by a CNC machine tool to make the glass sheet into a preset size and have a stepped edge and a slot for accommodating a sealing strip. Immediately afterwards, remove the defects and scratches on the glass surface through a polishing process, then remove the dirt and impurities on the glass surface through a cleaning agent, and then place the glass in a hot bending machine to bend its left and right sides into the required curved shape by heating and pressurizing. Then, place the glass in a tempering furnace for high-temperature treatment to form compressive stress on its surface. Finally, apply an anti-fingerprint oil film on the glass surface, and sequentially attach a functional film layer and an explosion-proof film layer on the back of the glass. Step 4: Manufacture a sealing strip. Prepare a first magnetic strip and a second magnetic strip, attach the first magnetic strip to the slot of the tempered glass sheet through double-sided tape, and then attach the second magnetic strip to the rear position of the screen laminating film through double-sided tape. Step 5: Assemble and laminate the film. Before leaving the factory, first bond and fix the U-shaped metal frame and the screen laminating film through an adhesive strip. During use, first tear off the release film on the back of the screen laminating film, and then mount the screen laminating film on the screen of the product to be laminated. During the lamination process, the corresponding laminating tool can be used to complete the lamination operation. After attachment, insert the tempered glass sheet into the space between the U-shaped metal frame and the screen laminating film along the rear of the U-shaped metal frame. During the insertion process, ensure that the moving direction of the tempered glass sheet is directly opposite to the insertion direction, and the corresponding auxiliary tool can be used to complete the insertion operation of the tempered glass sheet. And when the tempered glass sheet completely enters the space between the U-shaped metal frame and the screen laminating film, it is necessary to ensure that the first magnetic strip and the second magnetic strip are aligned and attracted to complete the assembly and lamination operation of the tempered film finished product.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: By adopting a tempered film that simultaneously has a screen laminating film and a tempered glass sheet, the screen laminating film is used for full-glue attachment to the screen to be laminated, while the tempered glass sheet is fixed to the screen laminating film by an edge fixing method.

[0020] When it is applied to a curved screen, through the structural design of combining a C-shaped metal frame with a pressing edge and a sealing strip after full-glue lamination of this screen lamination film, the tempered glass sheet can be firmly and stably restricted on the screen lamination film, ensuring that the screen lamination film and the tempered glass sheet are in close contact without moving. Especially after the tempered glass sheet is successfully installed between the C-shaped metal frame and the screen lamination film, the sealing strip is further used for the final fixing. The sealing strip uses double-sided adhesive to ensure firm lamination with the tempered glass sheet and the PET layer; it can make the attached tempered film fit more closely with the screen. And because the screen lamination film is a soft film, its full-glue lamination can well conform to the curvature of the curved screen for lamination, solving the problem that air bubbles are generated during the lamination of the tempered film due to large tolerances of the curved screen, and at the same time solving the situation that the tempered film is prone to detachment because the edge of the tempered film alone is not firmly attached to the edge of the screen to be laminated.

[0021] When applied to a flat screen, through the full-glue lamination of the screen lamination film and then with the help of the structural design of the C-shaped metal frame with a pressing edge and the sealing strip composed of the first magnetic strip and the second magnetic strip, the tempered glass sheet can be stably restricted on the screen lamination film. The sealing strip uses the magnetic attraction method to adsorb the rear side of the tempered glass sheet to the screen lamination film, and a slot is provided at the rear of the tempered glass sheet to accommodate the magnetic strip to avoid raising the overall rear part due to the sealing strip. Since the thickness of the second magnetic strip is less than that of the pressing edge, when assembling, the tempered glass sheet can squeeze the pressing edge and pass through the second magnetic strip to enter between the C-shaped metal frame and the screen lamination film to achieve a firm lamination. If the tempered glass sheet needs to be disassembled, a plug with an inclined surface will be equipped according to the product requirements. The plug is inserted between the first magnetic strip and the second magnetic strip to lift the second magnetic strip, and then the tempered glass sheet is pressed and pushed backward to be pulled out. In this way, with the cooperation of the first magnetic strip, the second magnetic strip and the slot, the tempered glass sheet is not only firmly fixed, but also can be disassembled with the help of corresponding tools, thereby achieving the repeated replacement of the tempered glass sheet. Based on the hard film with multiple functional structures, the function of the tempered film can be flexibly changed. For example, the tempered glass sheet can be a functional film such as anti-peeping, anti-blue light, fingerprint-proof, high-gloss, etc., and can be flexibly replaced according to different scene requirements of users. When the tempered glass sheet is broken, it can also be replaced separately.

[0022] The additional aspects and advantages of the present invention will be partly given in the following description, partly will become obvious from the following description, or will be understood through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] In the technical solutions of the present invention, it is mainly to provide a tempered glass film that simultaneously has a soft film and a hard film. The soft film is used for full-glue attachment to the screen to be pasted, and the hard film is fixed to the soft film by means of edge fixation. When it is applied to a curved screen, the attached tempered glass film can be more closely attached to the screen, solving the problem that the edge of the tempered glass film is not firmly attached to the edge of the screen to be pasted, resulting in the easy detachment of the tempered glass film. When it is applied to a flat screen, the hard film and the soft film can be set into a detachable structure, so that the hard film can be repeatedly replaced. On the basis of various hard films with various functional structures, the purpose of flexible replacement of the functions of the tempered glass film can be achieved, that is, the hard film can be an anti-peeping film, an anti-blue light film, an anti-fingerprint film, a high-gloss film, etc. functional films, which can be flexibly replaced according to the user's usage requirements for different scenarios. At the same time, when the hard film is broken, only the hard film can be replaced to a certain extent. The present invention will be described through multiple embodiments:

Embodiment 1

[0028] A manufacturing process of a tempered film with a fixed fitting base on the edge of a glass sheet, which is used to manufacture the above-mentioned tempered film with a fixed fitting base on the edge of a glass sheet, includes the following steps: Step 1, manufacture the screen bonding film 10. Prepare PET film material, OCA film material, bonding film material and release film material. The OCA film material and the bonding film material are respectively attached to the release film material through a laminating machine, and then the OCA film material and the bonding film material on the release film material are cut into the corresponding sizes and shapes of the OCA adhesive layer 13 and the bonding strip 11 through a film cutting machine. Then the PET film material is cut into the PET layer 12 through a film cutting machine. Finally, the OCA adhesive layer 13 and the bonding strip 11 are respectively positioned and attached to the PET layer 12 through a film pasting machine to manufacture the screen bonding film 10 for standby; Step 2, manufacture the U-shaped metal frame 20. Make a corresponding mold according to the size and structure of the U-shaped metal frame 20. Put the metal material for manufacturing the U-shaped metal frame 20 into the mold, and form the structure of the U-shaped metal frame 20 through a punching machine. Then put it on a dispensing machine through a positioning jig, and coat the material of the pressing edge 22 at the lower end of the fixed edge 21 through the dispensing machine; It should be noted that there are some inaccuracies or unclear parts in the original Chinese text, such as "对接于固定边21下端的台阶边31" which is not clearly expressed in a standard way. The above translation tries to make sense based on the overall context.Step 3: Fabricate the tempered glass sheet 30. Prepare the glass raw material, cut the glass raw material into a size suitable for processing, precisely process the glass sheet through a CNC numerical control machine tool, so that the glass sheet is processed into a preset size and has a stepped edge 31 and a slot 32 for accommodating the edge sealing strip 40. Immediately afterwards, remove the defects and scratches on the glass surface through a polishing process, then remove the dirt and impurities on the glass surface through a cleaning agent, then place the glass in a hot bending machine, and make its left and right sides bend into the required curved surface shape through heating and pressurization. Then place the glass in a tempering furnace for high-temperature treatment to form a compressive stress on its surface. Finally, coat a fingerprint-proof oil film on the glass surface, and attach an anti-blue light layer 36 and an explosion-proof film layer 33 on the back of the glass; Step 4: Fabricate the edge sealing strip 40. Prepare the double-sided adhesive strip 41 material, cut out a suitable double-sided adhesive strip 41 according to the size of the rear part of the tempered glass sheet 30, and paste and fix it at the corresponding position of the tempered glass sheet 30; then attach a release strip 42 on the double-sided adhesive strip 41, and perform a folding setting on the release strip 42 so that the extended end of the release strip 42 is located behind the tempered glass sheet 30; Step 5: Assemble the film. Before leaving the factory, first bond and fix the U-shaped metal frame 20 and the screen fitting film 10 through the bonding strip 11; during use, first tear off the release film on the back of the screen fitting film 10, then mount the screen fitting film 10 on the screen of the product to be film-attached. During the film-attaching process, the corresponding film-attaching tool can be used to complete the film-attaching operation. After attachment, insert the tempered glass sheet 30 into the space between the U-shaped metal frame 20 and the screen fitting film 10 along the rear of the U-shaped metal frame 20. During the insertion process, ensure that the moving direction of the tempered glass sheet 30 is facing the insertion direction, and the corresponding auxiliary tool can be used to complete the insertion operation of the tempered glass sheet 30. Finally, when the tempered glass sheet 30 completely enters the space between the U-shaped metal frame 20 and the screen fitting film 10, tear off the release strip 42, and then roll and press the double-sided adhesive strip 41 onto the screen fitting film 10 through a roller, thereby completing the assembly and film-attaching operation of the tempered film finished product.

[0029] The above embodiments are mainly used for adhering to the screen to be pasted with curved surfaces on both sides, and can also be used on flat screens. The screen bonding film 10 is in tight fit with the tempered glass sheet 30 through the PET layer 12, and the bonding strip 11 on the extension part 14 of the PET layer 12 can be adhesively fixed to the periphery of the U-shaped metal frame 20, so that all components are closely connected. At the same time, the left and right sides of the tempered glass sheet 30 are curved, and the screen bonding film 10 and the U-shaped metal frame 20 are adapted to the curved surface structure, and can be well adapted to the curvature of the curved screen for bonding. In this technical solution, the screen bonding film 10 is used as the soft layer, and the tempered glass sheet 30 is used as the hard layer. Through the structural design of the U-shaped metal frame 20 with a pressing edge 22 and the sealing strip 40 after the full-glue bonding of the screen bonding film 10, the tempered glass sheet 30 can be firmly and stably restricted on the screen bonding film 10, ensuring that there is close contact between the screen bonding film 10 and the tempered glass sheet 30 and no movement will occur. Especially after the tempered glass sheet 30 is successfully installed between the U-shaped metal frame 20 and the screen bonding film 10, the sealing strip 40 is further used for the final fixing. The sealing strip 40 uses double-sided tape, and a slot 32 is provided at the rear of the tempered glass sheet 30 in the structural design to accommodate the sealing strip 40, so that the overall rear part will not be raised due to the height of the sealing strip 40 after bonding, ensuring firm bonding with the tempered glass sheet 30 and the PET layer 12. On the basis that processes and costs permit, the positions where the sealing strip 40 is bonded to the tempered glass sheet 30 and the PET layer 12 can also be polished and roughened to make the adhesion of the sealing strip 40 more firm.

[0030] In addition, the extension type release strip 42 is used for the bonding of the sealing strip 40. The release strip 42 needs to be folded before leaving the factory so that its extended section can be behind the tempered glass sheet 30, thus ensuring that it will not touch the U-shaped metal frame 20 during the assembly process and affecting the assembly effect. With this extended structure, it can achieve the bonding of the sealing strip 40 after the tempered glass sheet 30 is assembled between the U-shaped metal frame 20 and the screen bonding film 10. That is, after the tempered glass sheet 30 is assembled between the U-shaped metal frame 20 and the screen bonding film 10, by tearing the release strip 42 in the reverse direction, the thickness of the release strip 42 needs to meet the requirement that it is less than the thickness of the pressing edge 22 in the dimension design, ensuring smooth tearing of the release strip 42 without causing excessive extrusion to the double-sided adhesive strip 41 and damaging the double-sided adhesive strip 41, so that the double-sided adhesive strip 41 on the sealing strip 40 is firmly bonded to the screen bonding film 10.

[0031] The width of each side of the U-shaped metal frame 20 and the width of the sealing strip 40 are both set between 2 mm and 3 mm, which can ensure sufficient strength to firmly restrict the tempered glass sheet 30, and within the range of 2 mm - 3 mm, it will not cause excessive occlusion to the edge of the screen, ensuring the normal use of the screen after pasting.

Example 2

[0033] A manufacturing process of a tempered film with a fixed fitting matrix on the edge of the glass sheet, which is used to manufacture the above-mentioned tempered film with a fixed fitting matrix on the edge of the glass sheet, includes the following steps: Step 1: Fabricate the screen laminating film 10.

Use a laminating machine to attach the OCA film material and the adhesive film material to the release film material respectively. Then, use a film cutting machine to cut the OCA film material and the adhesive film material on the release film material into the corresponding sizes and shapes of the OCA adhesive layer 13 and the adhesive strip 11. Next, use a film cutting machine to cut the PET film material into the PET layer 12. Finally, use a film pasting machine to position and attach the OCA adhesive layer 13 and the adhesive strip 11 to the PET layer 12 respectively to fabricate the screen laminating film 10 for standby. Step 2: Fabricate the U-shaped metal frame 20. Make a corresponding mold according to the size and structure of the U-shaped metal frame 20. Place the metal material for fabricating the U-shaped metal frame 20 into the mold, and use a stamping machine to stamp out the structure of the U-shaped metal frame 20. Then, place it on a dispensing machine through a positioning jig, and use the dispensing machine to coat the material of the pressing edge 22 at the lower end of the fixed edge 21. Step 3: Fabricate the tempered glass sheet 30. Prepare the glass raw material, cut the glass raw material into a suitable size for processing, and precisely process the glass sheet through a CNC numerical control machine tool to make the glass sheet processed into a preset size and have a stepped edge 31 and a slot 32 for accommodating the edge sealing strip 40. Immediately, remove the defects and scratches on the glass surface through a polishing process, then remove the dirt and impurities on the glass surface through a cleaning agent. Then, place the glass into a hot bending machine, heat and press it to make the left and right sides bend into the required curved surface shape. Next, place the glass into a tempering furnace for high-temperature treatment to form compressive stress on its surface. Finally, coat a layer of anti-fingerprint oil film on the glass surface, and sequentially attach a functional film layer and an explosion-proof film layer 33 to the back of the glass. Step 4: Fabricate the edge sealing strip 40. Prepare the first magnetic strip 43 and the second magnetic strip 44. Use double-sided tape to attach the first magnetic strip 43 into the slot 32 of the tempered glass sheet 30, and then use double-sided tape to attach the second magnetic strip 44 at the rear position of the screen laminating film 10. Step 5: Assemble and paste the film. Before leaving the factory, first bond and fix the U-shaped metal frame 20 and the screen laminating film 10 through the adhesive strip 11. During use, first tear off the release film on the back of the screen laminating film 10, and then mount the screen laminating film 10 on the screen of the product to be pasted. During the film pasting process, the corresponding film pasting device can be used to complete the film pasting operation. After pasting, insert the tempered glass sheet 30 between the U-shaped metal frame 20 and the screen laminating film 10 along the rear of the U-shaped metal frame 20. During the insertion process, ensure that the moving direction of the tempered glass sheet 30 is exactly the insertion direction, and the corresponding auxiliary tool can be used to complete the insertion operation of the tempered glass sheet 30. And when the tempered glass sheet 30 completely enters between the U-shaped metal frame 20 and the screen laminating film 10, it is necessary to ensure that the first magnetic strip 43 and the second magnetic strip 44 are aligned and attracted to complete the assembly and film pasting operation of the tempered film finished product.

[0034] The above embodiments are mainly used for adhering to the screen to be pasted on a straight screen. The screen laminating film 10 is in tight fit with the tempered glass sheet 30 through the PET layer 12, and the adhesive strip 11 on the extension part 14 of the PET layer 12 can be adhesively fixed to the periphery of the U-shaped metal frame 20, making the connection of each component tight. In this technical solution, the screen laminating film 10 is used as the soft layer, and the tempered glass sheet 30 is used as the hard layer. Through the full-glue lamination of the screen laminating film 10 and the structural design of combining the U-shaped metal frame 20 with a pressing edge 22 and the sealing strip 40, the tempered glass sheet 30 can be firmly and stably restricted on the screen laminating film 10, ensuring that the screen laminating film 10 and the tempered glass sheet 30 are in close contact and will not move. Especially after the tempered glass sheet 30 is successfully installed between the U-shaped metal frame 20 and the screen laminating film 10, the sealing strip 40 is further used for the final fixing. The sealing strip 40 adopts the structure of the first magnetic strip 43 and the second magnetic strip 44, which uses the magnetic attraction cooperation method to magnetically adsorb the rear side of the tempered glass sheet 30 to the screen laminating film 10. And in the structural design, a slot 32 is arranged at the rear part of the tempered glass sheet 30 to accommodate the first magnetic strip 43 and the second magnetic strip 44, so that the overall rear part will not be raised due to the height of the sealing strip 40 after lamination. And since the thickness of the second magnetic strip 44 is less than the thickness of the pressing edge 22, during the assembly process, the tempered glass sheet 30 can pass through the second magnetic strip 44 by squeezing the pressing edge 22 and then enter between the U-shaped metal frame 20 and the screen laminating film 10, ensuring a firm fit with the tempered glass sheet 30 and the PET layer 12.

[0035] When it is necessary to disassemble the tempered glass sheet 30, external tools are still needed, that is, corresponding shims will be equipped according to product requirements. The shim has a certain slope and is used to be inserted between the first magnetic strip 43 and the second magnetic strip 44, so as to remove the second magnetic strip 44 from the slot 32. Then, by maintaining a certain pressing force, the tempered glass sheet 30 is pressed and pushed backward, so that the tempered glass sheet 30 can be withdrawn from between the U-shaped metal frame 20 and the screen laminating film 10. Therefore, through the clamping cooperation of the first magnetic strip 43 and the second magnetic strip 44 combined with the slot 32 and the second magnetic strip 44, the tempered glass sheet 30 can be firmly fixed between the U-shaped metal frame 20 and the screen laminating film 10, and the detachable operation of the tempered glass sheet 30 can be realized on the basis of using corresponding tools such as shims.

[0036] The width of each side of the U-shaped metal frame 20 and the width of the sealing strip 40 are both set at 2 mm - 3 mm, which can ensure that there is enough strength to firmly restrict the tempered glass sheet 30. And within the range of 2 mm - 3 mm, it will not cause excessive occlusion to the edge of the screen, ensuring the normal use of the screen after pasting the film.

Example 3

[0038] A manufacturing process for a tempered film with a fixed fitting matrix on the edge of a glass sheet, which is used to manufacture the above-mentioned tempered film with a fixed fitting matrix on the edge of a glass sheet, includes the following steps: It should be noted that there is an unclear expression "对接于" in the original text, which is tentatively translated as "对接". If there is a more accurate expression, it can be adjusted accordingly.Step 1: Manufacture the screen laminating film 10. Prepare the PET film material, OCA film material, adhesive film material and release film material. Attach the OCA film material and the adhesive film material to the release film material respectively through a laminating machine. Then, cut the OCA film material and the adhesive film material on the release film material into the corresponding sizes and shapes of the OCA adhesive layer 13 and the adhesive strip 11 through a film cutting machine. Next, cut the PET film material into the PET layer 12 through a film cutting machine. Finally, attach the OCA adhesive layer 13 and the adhesive strip 11 to the PET layer 12 respectively through a film laminating machine to manufacture the screen laminating film 10 for standby; Step 2: Manufacture the U-shaped metal frame 20 and the edge sealing strip 40. Manufacture the corresponding molds according to the size and structure of the U-shaped metal frame 20 and the edge sealing strip 40. Put the metal materials for manufacturing the U-shaped metal frame 20 and the edge sealing strip 40 into the molds, and form an enclosed frame structure through a stamping machine. Then, place it on a dispensing machine through a positioning jig, and apply the material of the pressing edge 22 to the lower end of the fixed edge 21 through the dispensing machine; Step 3: Manufacture the tempered glass sheet 30. Prepare the glass raw material, cut the glass raw material into a suitable size for processing, and precisely process the glass sheet through a CNC numerical control machine tool to process the glass sheet into a preset size and have a stepped edge 31. Immediately, remove the defects and scratches on the glass surface through a polishing process. Then, remove the dirt and impurities on the glass surface through a cleaning agent. Then, put the glass into a hot bending machine, and make its left and right sides bend into the required curved surface shape through heating and pressurization. Then, put the glass into a tempering furnace for high-temperature treatment to form a compressive stress on its surface. Finally, coat a layer of anti-fingerprint oil film on the glass surface, and attach an anti-peeping layer 35 and an explosion-proof film layer 33 to the back of the glass in sequence; Step 4: Assemble and laminate the film. During use, first tear off the release film on the back of the screen laminating film 10, and then mount the screen laminating film 10 on the screen of the product to be laminated. During the laminating process, the corresponding laminating tool can be used to complete the laminating operation. After attachment,对接 the tempered glass sheet 30 and the U-shaped metal frame 20, and assemble the tempered glass sheet 30 into the structure enclosed by the U-shaped metal frame 20 and the edge sealing strip 40. Then, place the U-shaped metal frame 20 assembled with the tempered glass sheet 30 on the screen laminating film 10 in a positioned manner. Finally, bond and fix the U-shaped metal frame 20 and the edge sealing strip 40 through the adhesive strip 11, thereby completing the assembly and laminating operation of the tempered film finished product.

[0039] The above embodiments are mainly used for attaching to the to-be-laminated screen with curved surfaces on both sides, and can also be used on a flat screen. The screen laminating film 10 is in tight fit with the tempered glass sheet 30 through the PET layer 12, and the adhesive strip 11 on the extension part 14 of the PET layer 12 can be adhesively fixed to the periphery of the U-shaped metal frame 20 and the edge sealing strip 40, making the connection of each component tight. At the same time, the left and right sides of the tempered glass sheet 30 are curved, and the screen laminating film 10 and the U-shaped metal frame 20 are adapted to the curved surface structure, and can be well adapted to the curvature of the curved screen for lamination. In this technical solution, the screen laminating film 10 is used as a soft layer, and the tempered glass sheet 30 is used as a hard layer. Through the full-glue lamination of the screen laminating film 10 and the structural design of the U-shaped metal frame 20 with a pressing edge 22 combined with the edge sealing strip 40, the tempered glass sheet 30 can be firmly and stably restricted on the screen laminating film 10, ensuring close contact between the screen laminating film 10 and the tempered glass sheet 30 without movement.
