[0027] 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.

[0028] In the related technology, each film material of the backlight part also needs to be punched at the corresponding position of the front camera. The punching of the film material is usually achieved by die cutting. However, when the tool is cutting the film material, the film material is not cut and broken at the moment of contact with the film material, but it is broken after the film material is squeezed downward and deformed to a certain extent. The deformation will also extend from the cutting edge to the inside of the film material, causing deformation and damage to the film material near the front camera hole. After the light passes through the deformed and damaged part, the optical path changes compared with the theoretical design, and a similar ring-shaped bad area will be formed near the front camera on the screen, affecting the visual effect of the screen.

[0029] In order to solve the above technical problems, according to an embodiment of the present disclosure, a cutting jig is provided for cutting film materials, the cutting jig comprising: a clamping assembly, the clamping assembly comprising a first clamping portion and a second clamping portion, the first clamping portion and the second clamping portion respectively contacting two opposite sides of the film material to clamp the film material, the film material comprising a portion to be cut, the first clamping portion covering at least a portion of the film material and exposing the portion to be cut; a cutting assembly, the cutting assembly being movable relative to the clamping assembly in a cutting direction, the cutting assembly cutting the portion to be cut, the cutting direction having an angle with the surface of the portion to be cut.

[0030] The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects: the present disclosure clamps the film material near the part to be cut by a clamping assembly having a first clamping part and a second clamping part, and enables the cutting assembly to cut the part to be cut exposed by the clamping assembly, thereby reducing the deformation of the film material around the part to be cut, preventing the deformation area of ​​the film material from extending to the non-cutting part, thereby reducing the deformation area of ​​the film material and maintaining the design performance of the film material.

[0031] It can be understood that the cutting jig involved in the present disclosure can be applicable to the production process of any terminal listed below.

[0032] It is understandable that the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (User Equipment, UE), a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal, MT), etc., which is a device that provides voice and / or data connectivity to users.

It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0033] Figure 1 The figure is a schematic diagram of the structure of a cutting jig according to an exemplary embodiment. Figure 2 The figure is a schematic diagram of the structure of a cutting jig according to an exemplary embodiment. Figure 3 The figure is a schematic diagram of the structure of a cutting jig according to an exemplary embodiment. Figure 4 The figure is a schematic diagram of the structure of a cutting jig according to an exemplary embodiment.

[0034] In some embodiments, Figure 1-4 As shown, the cutting jig may include: a clamping component and a cutting component.

[0035] The clamping assembly can be used to clamp the film material 400 , and the clamping assembly may include a first clamping portion 10 and a second clamping portion 20 .

[0036] The first clamping portion 10 and the second clamping portion 20 can respectively contact the opposite sides of the film material 400 to clamp the film material 400. The first clamping portion 10 can cover at least a portion of the film material 400. By applying pressure and clamping the surface of the film material 400 by the first clamping portion 10 and the second clamping portion 20, deformation and sliding of the non-cutting area of ​​the film material 400 during the cutting process can be reduced.

[0037] The first clamping portion 10 may cover a non-cutting portion around the to-be-cut portion of the film material 400 and expose the to-be-cut portion of the film material 400 .

[0038] The cutting assembly can be used to cut the film material 400 , and the cutting assembly can move relative to the clamping assembly in the cutting direction, thereby cutting the film material 400 clamped and fixed by the clamping assembly.

[0039] The cutting direction may have an angle with the surface of the portion to be cut. For example, the cutting direction may have an acute angle with the surface of the portion to be cut, so that the cutting assembly can cut the film material at an angle to the surface of the film material.

[0040] Exemplarily, the cutting direction may also be at a right angle to the surface of the portion to be cut, so that the cutting assembly can cut the film material perpendicularly to the surface of the film material.

[0041] When the cutting assembly cuts the film material 400, the cutting assembly can deform a part of the film material 400 so that the film material 400 is cut off. Since the non-cutting portion of the film material 400 around the portion to be cut is clamped and fixed by the clamping assembly, the deformation of the non-cutting area of ​​the film material 400 during the cutting process is reduced. Therefore, the clamping assembly can prevent the deformed area of ​​the film material 400 from extending to the non-cutting portion, thereby greatly reducing the deformed area of ​​the film material 400.

[0042] In some embodiments, the film material 400 may be a polarizer of a liquid crystal display.

[0043] In some embodiments, the first clamping portion 10 includes a first through hole 60 penetrating the first clamping portion 10 , and the first clamping portion 10 may expose the portion of the film material 400 to be cut through the first through hole 60 .

[0044] The cutting assembly may pass through the first through hole 60 to cut the to-be-cut portion of the film material 400 exposed by the first through hole 60 .

[0045] Exemplarily, the cutting assembly may move along the axial direction of the first through hole 60 and pass through the first through hole 60 to cut the to-be-cut portion of the film material 400 exposed by the first through hole 60 .

[0046] When the cutting assembly cuts the film material 400 through the first through hole 60, the cutting assembly can deform a part of the film material 400 so that the to-be-cut portion of the film material 400 is sheared off. Since the non-cutting portion of the film material 400 around the to-be-cut portion is clamped and fixed by the clamping assembly, the deformation of the non-cutting region of the film material 400 during the cutting process is reduced, and therefore the clamping assembly can prevent the deformed region of the film material 400 from extending to the non-cutting portion, thereby greatly reducing the deformed region of the film material 400.

[0047] In some embodiments, Figure 1-4 As shown, the cutting assembly may include a base 30 and a first cutting piece 40. The base 30 may move relative to the clamping assembly. The first cutting piece 40 may be arranged on a side of the base 30 facing the clamping assembly. The base 30 may drive the first cutting piece 40 to move relative to the clamping assembly, so that the first cutting piece 40 may approach and cut the film material 400.

[0048] The cutting jig may include a discharge assembly. After the cutting assembly cuts the film material 400, the discharge assembly may separate the cut portion 402 of the film material 400 from the first cutting piece 40, thereby preventing the cut portion 402 of the film material 400 from remaining on the first cutting piece 40, and preventing the remaining film material 400 from interfering with the cutting operation, so as to facilitate the cutting assembly to perform the next cutting operation.

[0049] The cut portion 402 of the film material 400 may be a portion of the film material 400 that is discarded after being cut. For example, when the cutting assembly cuts a through hole on the film material 400, the cut portion 402 may be a circular film material 400 corresponding to the through hole.

[0050] In some embodiments, the ejector assembly may also be used to separate the cut portion 402 of the film 400 from the clamping assembly.

[0051] In some embodiments, the cutting piece may be an annular cutting piece, so that the cutting piece can cut and form a through hole on the film material 400 .

[0052] In some embodiments, Figure 3 As shown, the base 30 may be provided with a second through hole 70 facing the film material 400 .

[0053] The discharge assembly may include an air pump 90 , which may be used to blow air toward the cut portion 402 of the film 400 through the second through hole 70 to separate the cut portion 402 of the film 400 from the first cutting member 40 .

[0054] After the cutting assembly cuts the film material 400, the air pump 90 can blow airflow toward the cut portion 402 of the film material 400 through the second through hole 70. The cut portion 402 of the film material 400 can be separated from the first cutting piece 40 under the action of the airflow, thereby preventing the cut portion 402 of the film material 400 from remaining on the first cutting piece 40, and preventing the remaining film material 400 from interfering with the cutting operation, so as to facilitate the cutting assembly to perform the next cutting operation.

[0055] In some embodiments, Figure 4 As shown, the discharge assembly includes: a movable member 80 , which can move relative to the base 30 . Exemplarily, the movable member 80 can move in a direction perpendicular to the surface of the film material 400 .

[0056] After the cutting assembly cuts the film material 400, the movable part 80 can move relative to the base 30, so that the movable part 80 abuts against the cut portion 402 of the film material 400 and applies pressure to the cut portion 402, thereby separating the cut portion 402 of the film material 400 from the first cutting piece 40, preventing the cut portion 402 of the film material 400 from remaining on the first cutting piece 40, and preventing the remaining film material 400 from interfering with the cutting operation, so as to facilitate the cutting assembly to perform the next cutting operation.

[0057] Figure 5 is a schematic structural diagram of a first clamping portion according to an exemplary embodiment.

[0058] In some embodiments, Figure 1-5 As shown, the first clamping portion 10 may include a first clamping surface 11 for clamping the film material 400 , and the first clamping surface 11 is provided with an anti-slip portion.

[0059] By providing an anti-slip portion on the first clamping surface 11, the friction between the first clamping surface 11 and the surface of the film material 400 can be increased, thereby reducing the relative movement between the film material 400 and the first clamping surface 11, thereby reducing the displacement of the film material 400 clamped by the clamping component relative to the clamping component, and improving the stability of the clamping component clamping the film material 400.

[0060] Exemplarily, the anti-skid portion may be a component made of a material with a relatively large friction coefficient, or may be a component having an anti-skid pattern on the surface.

[0061] In some embodiments, Figure 1-4 As shown, the surface of the film material 400 may be provided with a plurality of first protrusions 401

[0062] Exemplarily, when the film material 400 is an optical component, the first protrusion 401 may be a protrusion structure for deflecting light.

[0063] The anti-slip portion may be provided with a plurality of second protrusions 12 . By using the plurality of protrusions as the anti-slip portion, the clamping stability between the clamping assembly and the surface of the film material 400 may be improved.

[0064] When the clamping assembly clamps the film material 400, the first protrusion 401 and the second protrusion 12 can adapt to each other so that the first clamping surface 11 and the surface of the film material 400 fit together, thereby reducing the relative movement between the film material 400 and the first clamping surface 11, thereby reducing the displacement of the film material 400 clamped by the clamping assembly relative to the clamping assembly, and improving the stability of the clamping assembly in clamping the film material 400.

[0065] In some embodiments, Figure 1As shown, the second clamping portion 20 may be provided with a discharge channel 22, and the discharge channel 22 may have an inlet 4, and the inlet 4 may face the cut portion of the film material 400. After the cutting assembly cuts the film material 400, the discharge assembly may allow the cut portion 402 of the film material 400 to enter the discharge channel 22.

[0066] The discharge channel 22 can serve as a discard path for the cut portion 402 of the film material 400 , and collect the cut portion 402 of the film material 400 for unified processing.

[0067] In addition, a cutting component is used to cut the film material 400 on the side where the first clamping portion 10 is provided, and a discharge channel 22 is provided on the side where the second clamping portion 20 is provided. Therefore, when the cutting component cuts the film material 400, when the cutting component completes the cutting but has not yet moved away from the film material 400, the cut portion 402 can be discharged from the discharge channel 22, thereby improving the operating speed of the cutting jig.

[0068] In some embodiments, the discharge channel 22 can be arranged opposite to the first through hole 60, so that the discharge channel 22 can provide a larger movement space for the cutting component. When the cutting component cuts the film material 400 through the first through hole 60, the cutting component can pass through the first through hole 60 and move to the discharge channel 22, so that the cutting component can penetrate the film material 400, thereby reducing the adhesion between the cut part 402 and the non-cutting part, and improving the cutting efficiency of the cutting piece.

[0069] In some embodiments, Figure 1 As shown, the discharge channel 22 includes an outlet 5 arranged opposite to the inlet 4, and the size of the inlet 4 is smaller than that of the outlet 5.

[0070] The size of the feed inlet 4 includes one of the diameter of the feed inlet 4, the width of the feed inlet 4 and the area of ​​the feed inlet 4;

[0071] The size of the discharge port 5 includes one of a diameter of the discharge port 5 , a width of the discharge port 5 , and an area of ​​the discharge port 5 .

[0072] The cut portion 402 of the film material 400 can enter the discharge channel 22 from the inlet 4 under the action of the discharge assembly, and then leave the discharge channel 22 from the outlet 5 .

[0073] The size of the feed port 4 can be smaller than that of the discharge port 5. By configuring the size of the feed port 4 to be smaller than that of the discharge port 5, the phenomenon of the cut portion 402 of the film material 400 hanging on the wall is reduced, so that the cut portion 402 of the film material 400 can smoothly enter the discharge channel 22 from the feed port 4 and move to the discharge port 5.

[0074] In some embodiments, the size of the feed port 4 may include one of the diameter of the feed port 4, the width of the feed port 4, and the area of ​​the feed port 4. Exemplarily, when the feed port 4 is circular in the plane where the feed port 4 is located, the size of the feed port 4 may be the diameter of the feed port 4; when the feed port 4 is polygonal in the plane where the feed port 4 is located, the size of the feed port 4 may be the width or length of the feed port 4; the size of the feed port 4 may also be the area of ​​the feed port 4, but the present disclosure is not limited thereto.

[0075] The size of the discharge port 5 may include one of the diameter of the discharge port 5, the width of the discharge port 5, and the area of ​​the discharge port 5. Exemplarily, when the discharge port 5 is circular in the plane where the discharge port 5 is located, the size of the discharge port 5 may be the diameter of the discharge port 5; when the discharge port 5 is polygonal in the plane where the discharge port 5 is located, the size of the discharge port 5 may be the width or length of the discharge port 5; the size of the discharge port 5 may also be the area of ​​the discharge port 5, but the present disclosure is not limited thereto.

[0076] In some embodiments, Figure 1 As shown, the cutting assembly includes: a second cutting member 50 , which can be disposed on the second clamping portion 20 , and the cutting edge of the second cutting member 50 faces the portion of the film material 400 to be cut.

[0077] By providing a second cutting piece 50 with a cutting edge facing the part to be cut of the film material 400 in the second clamping portion 20, the first cutting piece 40 and the second cutting piece 50 can respectively apply pressure to the film material 400 from two opposite sides of the film material 400, thereby reducing the maximum pressure received by a single side surface of the film material 400, thereby reducing the deformation of the film material 400 during the cutting process and improving the shearing efficiency of the cutting assembly on the film material 400.

[0078] In some embodiments, Figure 1 As shown, the second clamping portion 20 may include a second clamping surface 21 for clamping the film material 400 , the discharge channel 22 includes a side wall, and an edge formed by the intersection of the second clamping surface 21 and the side wall may be the second cutting piece 50 .

[0079] In some embodiments, Figure 5 As shown, the first clamping portion 10 may include a first portion 101 and a second portion 102 which are stacked, and the first clamping surface 11 may be disposed on the second portion 102 , that is, when the clamping assembly clamps the film 400 , the second portion 102 contacts the film 400 .

[0080] The hardness of the first portion 101 may be greater than or equal to the hardness of the second portion 102 , and the hardness of the second portion 102 may be less than the hardness of the film material 400 .

[0081] By making the hardness of the first part 101 greater than or equal to the hardness of the second part 102, the first part 101 can be used as the skeleton structure of the first clamping part 10 to provide support for the first clamping part 10 and maintain the shape of the first clamping part 10. By making the hardness of the second part 102 less than the hardness of the film 400, the deformation of the film 400 when the clamping assembly clamps the film 400 can be reduced, thereby reducing the situation where the clamping assembly clamps the film 400 and causes irreversible deformation of the film 400, and reducing the damage to the film 400 caused by the clamping assembly.

[0082] In some embodiments, the first part 101 is one or more of a rubber part, a silicone part, a resin part, and a plastic part.

[0083] In some embodiments, the first cutting member 40 may include a first inclined surface 41 and a second inclined surface 42 having an angle, the first inclined surface 41 contacts the non-cutting portion of the film material 400, the second inclined surface 42 contacts the to-be-cut portion of the film material 400, and the angle between the first inclined surface 41 and the surface of the film material 400 is smaller than the angle between the second inclined surface 42 and the surface of the film material 400. When the inclined surface of the first cutting member 40 presses down the film material 400, the smaller the angle between the inclined surface and the surface of the film material 400, the smaller the oblique force having an angle with the surface of the film material 400 applied by the cutting member to the film material 400, which can reduce the deformation of the film material 400 caused by the oblique force.

[0084] In some embodiments, the first inclined surface 41 is at a right angle to the surface of the film 400 , thereby further reducing the oblique force on the non-cut portion of the film 400 and reducing deformation of the non-cut portion of the film 400 caused by the oblique force.

[0085] In some embodiments, the cutting assembly mainly plays a cutting role, with a first through hole 60 arranged in the middle and a first cutting piece 40 arranged at the lower end. When the cutting assembly moves downward, the first cutting piece 40 plays a major cutting role to cut the film material 400. The upper surface of the second clamping part 20 is flat, and is mainly used to carry the film material 400. The second cutting piece 50 of the second clamping part 20 cooperates with the cutting assembly to shear the film material 400. A discharge channel 22 is arranged in the middle of the cutting piece corresponding to the punching position of the film material 400 for the discharge of waste. After the film material 400 is cut, the first through hole 60 of the cutting assembly passes high-pressure gas to blow the film material 400 downward into the discharge channel 22 to prevent waste from being stuck in the cutting assembly or the second clamping part 20 and other parts. The lower surface of the first clamping portion 10 is arranged with a membrane material 400 structure that cooperates with the membrane material 400 structure on the upper surface of the membrane material 400. When the first clamping portion 10 presses down the membrane material 400, the microstructures of the two can be aligned with each other. A first through hole 60 is arranged in the middle of the first clamping portion 10 corresponding to the position where the membrane material 400 is punched, so that the cutting component can be cut in smoothly.

[0086] When cutting the film 400, the first clamping part 10 is pressed down, and the film 400 structure on its lower surface is aligned with the film 400, and a certain force is applied to press the film 400 to prevent the film 400 from moving. When the cutting assembly starts to move down for cutting, the film 400 near the first cutting piece 40 is deformed and cut off by shearing. Because the film 400 around the circular hole is pressed, and the film 400 structure of the film 400 is in contact with the first clamping part 10, the deformation area near the first cutting piece 40 is prevented from extending outward, so that the range of the deformation area is greatly reduced, so that the light passing through the film 400 no longer has abnormalities. When the first cutting piece 40 of the cutting assembly begins to enter the second cutting piece 50 of the second clamping part 20, the film 400 has been completely cut off. At this time, the first through hole 60 of the cutting assembly can be passed with high-pressure gas to discharge the cut circular hole waste to prevent the cut part 402 from getting stuck or static electricity from adhering to the surface of the cutting piece and affecting the next cutting action.

[0087] The first cutting piece 40 of the cutting assembly and the second cutting piece 50 of the second clamping part 20 are made of metal, have relatively sharp edges and longer durability. There is a certain gap between the cutting assembly and the first clamping part 10 and the second clamping part 20 to prevent the cutting piece from being damaged by collision between the cutting assembly and the first clamping part 10 and the second clamping part 20. The membrane material 400 structure of the first clamping part 10 is made of soft rubber material to prevent other damage to the microstructure of the membrane material 400 after contact with the membrane material 400. The main body of the first clamping part 10 is made of metal, so that it has good strength to prevent deformation.
