Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a peeling device, peeling method and cutting tool. Background Technology

[0002] In the manufacturing process of display panels, especially flexible display panels, the display panel is fabricated on a glass substrate, and then the finished display panel is peeled off the glass substrate. This process utilizes peeling equipment. The peeling equipment uses blades to separate the display panel from the glass substrate. The blades are mounted on a fixture base, and the blade shank needs to be chamfered to fit the base. When the cutting edge of the blade wears excessively, the blade must be scrapped and replaced with a new one, increasing the cost of the peeling operation. Summary of the Invention

[0045] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description in order to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples thereof.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The embodiments will now be described in detail with reference to the accompanying drawings.

[0047] Relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0048] It should be understood that when describing the structure of a component, when referring to a layer or region as being "above" or "on top of" another layer or region, it can mean that it is directly above the other layer or region, or that it contains other layers or regions between it and the other layer or region. Furthermore, if the component is flipped over, that layer or region will be located "below" or "under" the other layer or region.

[0049] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0050] It should be understood that in the embodiments of this application, "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean that B is determined solely based on A; B can also be determined based on A and / or other information.

[0051] The applicant discovered that during the fabrication of flexible display panels, various film layers for the flexible display panel are created on a glass substrate. After the flexible display panel is fabricated, it needs to be peeled off from the glass substrate to obtain the finished product. This peeling process requires specialized peeling equipment. The peeling tool is inserted between the flexible display panel and the glass substrate and moves unidirectionally perpendicular to its extension direction, causing the cutting edge to peel the flexible display panel and glass substrate apart. The tool is then fed further, separating the display panel and glass substrate row by row until they are completely peeled off. During continuous peeling operations, the cutting edge of the tool wears down until the tool is worn out. Therefore, the tool is consumed in large quantities during continuous peeling operations, increasing the cost of the continuous peeling process.

[0052] Based on the above analysis, the applicant proposes a peeling device, a peeling method, and a cutting tool. The peeling device includes a peeling drive mechanism, a cutting tool base, and a cutting tool. The peeling drive mechanism itself is movable along a first direction and can also drive the cutting tool base to move along a second direction, causing the cutting tool base and the cutting tool connected to the cutting tool base to move along the first and / or second directions. The mounting part of the cutting tool is inserted into the mounting groove of the cutting tool base, and the positioning notch of one of the first positioning edges or the second positioning edge of the cutting tool abuts against the positioning part in the mounting groove, fixing the relative position of the cutting tool and the cutting tool base. In the process of using the peeling device of this application embodiment, when the first cutting edge of the cutting part is worn, the cutting tool can be flipped. At this time, the positioning notch of the other of the first positioning edge or the second positioning edge abuts against the positioning part in the mounting groove, fixing the relative position of the cutting tool and the cutting tool base. The second cutting edge can be used to peel the flexible display panel and the glass substrate. In the embodiments of this application, both the first cutting edge and the second cutting edge of the cutting tool can be used to peel the flexible display panel and the glass substrate, which can make fuller use of the cutting tool, extend the service life of the cutting tool, and reduce the number of cutting tools consumed and reduce operating costs during continuous peeling operations of flexible display panels and glass substrates.

[0054] Please see Figures 1 to 5This application provides a peeling device including a peeling drive mechanism 1, a tool base 2, and a tool 3. The peeling drive mechanism 1 is movably disposed along a first direction A1; the tool base 2 is connected to the peeling drive mechanism 1, and the peeling drive mechanism 1 drives the tool base 2 to move relative to the peeling drive mechanism 1 along a second direction A2, so that the tool base 2 moves along the first direction A1 and / or the second direction A2, where the first direction A1 and the second direction A2 are perpendicular; the tool base 2 includes a mounting groove 21 extending along the first direction A1 and at least one positioning portion 211 disposed within the mounting groove 21; the tool 3 includes a cutting portion 31 and a mounting portion 32, the mounting portion 32 having a first positioning edge and a second positioning edge opposite each other along the second direction A2, the first positioning edge and the second positioning edge... Both positioning edges are provided with positioning notches 323; the mounting part 32 is inserted into the mounting groove 21, and the positioning part 211 abuts against the positioning notches 323 to fix the relative position of the tool 3 and the tool base 2. The distance from the positioning notch 323 located on the first positioning edge to the cutting part 31 along the first direction A1 is D1, and the distance from the positioning notch 323 located on the second positioning edge to the cutting part 31 along the first direction A1 is D2, D1=D2; the cutting part 31 extends along the first direction A1, and at least part of the cutting part 31 is located outside the mounting groove 21. The cutting part 31 includes a first cutting edge 311 and a second cutting edge 312 arranged opposite to each other along the second direction A2.

[0055] The peeling device in this application embodiment can be used for peeling electronic products from substrates, wherein the electronic products include, but are not limited to, flexible display panels. For ease of explanation, this application embodiment uses a flexible display panel as an example of the electronic product, but it should not be construed as a limitation on electronic products.

[0056] When using the peeling device of this embodiment to peel a flexible display panel and a glass substrate, the unpeeled flexible display panel and glass substrate are flat sheets, and their planes are parallel to the first direction A1 and the second direction A2. The peeling drive mechanism 1 is movably disposed along the first direction A1. The cutter base 2 is connected to the peeling drive mechanism 1 and moves relative to the peeling drive mechanism 1 along the second direction A2. The cutter 3 is mounted on the cutter base 2; therefore, the cutter 3 and the cutter base 2 can move along the first direction A1 and / or the second direction A2. As the peeling drive mechanism 1 moves along the first direction A1, the cutter 3 also moves along the first direction A1, allowing it to be inserted between the flexible display panel and the glass substrate. Then, the peeling drive mechanism 1 drives the cutter base 2 to move along the second direction A2, and the cutter 3 also moves along the second direction A2, peeling the flexible display panel and glass substrate apart within the area swept by the cutter 3. Exemplarily, the peeling drive mechanism 1 uses a slide rail slider to drive the cutter base 2 to move along the second direction A2. It should be noted that the peeling drive mechanism 1, the cutter base 2, and the cutter 3 can be set up as a set. In the peeling device of this application embodiment, multiple sets of peeling drive mechanisms 1, cutter base 2, and cutter 3 can be set up to improve the peeling operation efficiency of a single peeling device.

[0057] The tool base 2 has a mounting groove 21 extending along the first direction A1. When installing the tool 3, the mounting part 32 of the tool 3 needs to be inserted into the mounting groove 21. When the positioning part 211 in the mounting groove 21 abuts against the positioning notch 323 of the mounting part 32 along the first direction A1, the tool 3 is fully inserted into the tool base 2. The relative position of the tool 3 and the tool base 2 is fixed. The position of the tool 3 can be adjusted by adjusting the position of the tool base 2, thereby enabling the tool 3 to peel the flexible display panel and the glass substrate at a preset position. During this process, the first cutting edge 311 or the second cutting edge 312 of the cutting part 31 will separate the flexible display panel and the glass substrate, achieving the purpose of peeling the flexible display panel and the glass substrate.

[0058] In this embodiment, the mounting part 32 has a first positioning edge and a second positioning edge on opposite sides along the second direction A2, and the cutting part 31 has a first cutting edge 311 and a second cutting edge 312 on opposite sides along the second direction A2. The correspondence between the first positioning edge, the second positioning edge, the first cutting edge 311, and the second cutting edge 312 is not limited. In this embodiment, the example is that the first positioning edge and the first cutting edge 311 are located on the same side of the tool 3, and the second positioning edge and the second cutting edge 312 are located on the same side of the tool 3.

[0059] During the initial installation of the cutting tool 3, one of the first cutting edge 311 and the second cutting edge 312 is used to separate the flexible display panel and the glass substrate. When the first cutting edge 311 is used to separate the flexible display panel and the glass substrate, the positioning part 211 abuts against the positioning notch 323 of the first positioning edge. After the first cutting edge 311 is severely worn, the cutting tool 3 is removed from the cutting tool base 2, rotated 180°, flipped over, and reinstalled, so that the positioning part 211 abuts against the positioning notch 323 of the second positioning edge. At this time, the second cutting edge 312 can also be used to separate the flexible display panel and the glass substrate. Therefore, in this embodiment, the first positioning edge and the second positioning edge on both sides of the mounting part 32 of the tool 3 along the second direction A2 have the same structure. The positioning notches 323 of the first positioning edge and the second positioning edge can both abut against the positioning part 211. The tool 3 can be mounted on the tool base 2 before and after being rotated 180°, so that the first cutting edge 311 and the second cutting edge 312 on both sides of the cutting part 31 of the tool 3 along the second direction A2 can be utilized, thereby roughly doubling the service life of the tool 3. By extending the service life of the tool 3, the cost of continuous peeling operation can be significantly reduced.

[0060] Furthermore, the distance D1 from the positioning notch 323 at the first edge to the cutting part 31 along the first direction A1, and the distance D2 from the positioning notch 323 at the second edge to the cutting part 31 along the first direction A1, are equal. This means that, given the fixed position of the tool base 2, whether the first cutting edge 311 or the second cutting edge 312 is used to separate the flexible display panel and the glass substrate, the area separated by the tool 3 is the same when the tool 3 moves along the second direction A2. Therefore, before and after the tool 3 flips over, the influence on the control parameters of the tool 3's movement is reduced, thus minimizing the impact of the tool 3 reinstallation process on the efficiency of continuous peeling operations.

[0061] Figure 6 This is an exploded view of the cutting tool and tool base of the stripping device according to an embodiment of this application. Figure 7 This is another exploded view of the blade and blade base of the stripping device according to an embodiment of this application.

[0062] Further, please refer to Figure 6 and Figure 7The positioning part 211 has a first abutting surface 211a intersecting the first direction A1, and the positioning notch 323 has a second abutting surface 323a intersecting the first direction A1. The first abutting surface 211a abuts against the second abutting surface 323a. When the first abutting surface 211a of the positioning part 211 abuts against the second abutting surface 323a of the positioning notch 323 along the first direction A1, it indicates that the mounting part 32 and the mounting groove 21 have been inserted into place, and the relative position of the cutter 3 and the cutter base 2 is determined. The cutter 3 is moved by moving the cutter base 2 so that the cutting part 31 of the cutter 3 can peel the flexible display panel and the glass substrate apart. It can be understood that the first abutting surface 211a and the second abutting surface 323a can be flat or curved; their shapes can be the same, and abutting is achieved through surface contact; their shapes can also be different, and abutting is achieved through line contact or point contact.

[0063] Further reading Figure 6 Both the first abutment surface 211a and the second abutment surface 323a are planar, and the angle between the first abutment surface 211a and the first direction A1 is 45°. The second abutment surface 323a can be regarded as the chamfered surface of the mounting part 32 of the tool 3. This chamfered surface is located at the connection of the edges of the mounting part 32 along the first direction A1 and the second direction A2, which can reduce the manufacturing difficulty and cost of the tool 3 and the tool base 2. The first abutment surface 211a and the second abutment surface 323a abut each other in the form of surface contact, so that the tool base 2 can provide stable support for the tool 3 along the first direction A1.

[0064] Further reading Figure 7 Both the first abutment surface 211a and the second abutment surface 323a are planar, with the first abutment surface 211a perpendicular to the first direction A1. The second abutment surface 323a can be considered as a stepped surface of the mounting part 32, formed by the sidewall of a rectangular notch located at the junction of the edges of the mounting part 32 along the first direction A1 and the second direction A2. This also reduces the manufacturing difficulty and cost of the tool 3 and the tool base 2. The first abutment surface 211a and the second abutment surface 323a abut against each other in a surface contact manner, enabling the tool base 2 to provide stable support for the tool 3 along the first direction A1.

[0065] Further reading Figure 6 and Figure 7The projection of the second abutment surface 323a along the first direction A1 has a length along the second direction A2 greater than or equal to 2mm. Considering that the length of the tool 3 along the first direction A1 is approximately 50-60mm and the width along the second direction A2 is approximately 10-20mm, the length of the second abutment surface 323a along the second direction A2 should be sufficiently large to provide limiting and support functions; that is, the length along the second direction A2 should be greater than or equal to 2mm. For example, when both the first abutment surface 211a and the second abutment surface 323a are planar, and the angle between the first abutment surface 211a and the first direction A1 is 45°, the second abutment surface 323a can be considered as a 2mm chamfered surface of the mounting part 32.

[0066] Figure 8 This is another top view schematic diagram of the blade of the peeling device according to an embodiment of this application.

[0067] Further, please refer to Figure 8 The distance from the first cutting edge 311 to the mounting portion 32 along the first direction A1 is L1, and the distance from the second cutting edge 312 to the mounting portion 32 along the first direction A1 is L2, where L1 = L2. The first cutting edge 311 and the second cutting edge 312 have the same structure. Before and after the tool 3 is rotated 180°, the first cutting edge 311 and the second cutting edge 312 peel off the flexible display panel and the glass substrate respectively, and their peeling capabilities for the flexible display panel and the glass substrate are also the same. Therefore, during the initial installation of the tool 3, it is not necessary to distinguish whether the positioning notch 323 of the first mounting edge 321 abuts against the positioning portion 211 of the mounting groove 21, or whether the positioning notch 323 of the second mounting edge 322 abuts against the positioning portion 211 of the mounting groove 21, thus reducing the difficulty of installing the tool 3.

[0068] Further reading Figure 8 The length of the first cutting edge 311 along the first direction A1 is greater than or equal to 30 mm, and the width of the first cutting edge 311 along the perpendicular direction A1 is greater than or equal to 5 mm. The dimensions of the first cutting edge 311 and the second cutting edge 312 are equal. Considering that the length of the tool 3 along the first direction A1 is approximately 50-60 mm and the width along the second direction A2 is approximately 10-20 mm, the dimension of the first cutting edge 311 should be large enough to increase the area that the tool 3 can peel off from the flexible display panel and the glass substrate during a single peeling operation, thereby improving the efficiency of continuous peeling operations. It is understood that the length of the first cutting edge 311 along the first direction A1 should not be too large. An excessively large first cutting edge 311 will increase the tangential force on the tool 3 during a single peeling operation, which may easily cause damage to the tool 3.

[0069] Furthermore, the Rockwell hardness of the first cutting edge 311 and the Rockwell hardness of the second cutting edge 312 are both 50-62 HRC, which can meet the requirements for peeling the flexible display panel from the glass substrate, reduce the risk of scratching the flexible display panel, and resist the wear of the first cutting edge 311 and the second cutting edge 312 during the peeling process.

[0070] Further reading Figure 8 The difference between the thickness of the cutting tool 3 and 0.6mm is less than the preset error. For example, the preset error is 0.1mm, which means that the thickness of the cutting tool 3 can be 0.5mm-0.7mm. If the thickness is too large, it will be more difficult for the cutting tool 3 to be inserted between the flexible display panel and the glass substrate, and it will also increase the amount of material used in the cutting tool 3, thereby increasing the cost of the cutting tool 3. If the thickness is too small, it will reduce the structural strength of the cutting tool 3, especially the bending strength of the cutting tool 3 perpendicular to the first direction A1 and the second direction A2, and it will also reduce the wear resistance of the cutting tool 3.

[0072] Further, please refer to Figure 9 and Figure 10 The cutting tool 3 has a first surface 3a and a second surface 3b opposite to each other along the thickness direction of the cutting tool 3, and the mounting groove 21 has a mounting groove opening 212 along the thickness direction of the cutting tool 3; at least a portion of the first surface 3a and the second surface 3b are in contact with the cutting tool base 2, and at least a portion of the other is exposed to the mounting groove opening 212.

[0073] When the tool 3 is inserted into the mounting slot 21, a portion of the mounting part 32 of the tool 3 will be exposed at the mounting slot opening 212, making it easy to check the status of the mounting part 32 of the tool 3. When the mounting slot opening 212 occupies the side wall of the mounting slot 21, exposing the inside of the mounting slot 21, the mounting part 32 of the tool 3 can also be inserted into the mounting slot 21 through the mounting slot opening 212, thus simplifying the installation process of the tool 3 and the tool base 2. Considering that the first mounting edge 321 and the second mounting edge 322 of the tool 3 have the same structure, and the first cutting edge 311 and the second cutting edge 312 have the same structure, when installing the tool 3, the first surface 3a can contact the inner wall of the mounting slot 21, or the tool 3 can be rotated 180° and the second surface 3b can contact the inner wall of the mounting slot 21.

[0074] Figure 11 This is a schematic diagram of the structure of a cutting tool in a peeling device according to an embodiment of this application. Figure 12 This is another schematic diagram of the installation of the blade and blade base of the peeling device according to an embodiment of this application.

[0075] Further, please refer to Figure 11 and Figure 12 The mounting part 32 includes a mounting hole 324 extending through the thickness direction of the tool 3. The orthographic projection of the mounting hole 324 on the first surface 3a overlaps with the orthographic projection of the mounting groove opening 212 on the first surface 3a. The tool 3 and the tool base 2 are fixedly connected by a fastener 4, which passes through the mounting hole 324.

[0076] When the positioning notch 323 of the tool 3 abuts against the positioning part 211 of the tool base 2, the tool 3 and the tool base 2 are installed in place. The relative position of the tool 3 and the tool base 2 is fixed by the fastener 4. For example, the fastener 4 can be a bolt. The fastener 4 passes through the mounting hole 324 and is threaded to the tool base 2. The nut of the fastener 4 presses the tool 3 into the mounting groove 21, thereby reducing the risk of the tool 3 falling off during the peeling operation.

[0077] Further reading Figure 11 and Figure 12 The cross-sectional shape of the mounting hole 324 is a strip extending along the first direction A1. When there is an error in the machining of the tool 3 and the tool base 2, the strip-shaped mounting hole 324 can compensate for the dimensional error, provided that the positioning notch 323 of the tool 3 abuts against the positioning part 211 of the tool base 2.

[0078] Figure 13 This is a schematic diagram of another structure of the blade base of the peeling device according to an embodiment of this application.

[0079] Further, please refer to Figure 13 The tool base 2 also includes a base body 23 and a movable part 22. The base body 23 is connected to the peeling drive mechanism 1, and the movable part 22 is movably connected to the base body 23 along the first direction A1. The mounting groove 21 is provided in the movable part 22.

[0080] The mounting slot 21 is provided on the movable part 22, so the cutter 3 is detachably fixedly connected to the movable part 22. Since the base body 23 is connected to the peeling drive mechanism 1, after the cutter 3 is connected to the movable part 22, the movable part 22 can be moved relative to the base body 23, allowing for fine-tuning of the relative position of the cutter 3 to the peeling drive mechanism 1. This makes the peeling operation more precise. For example, the base body 23 may be provided with a groove extending along the first direction A1, and the movable part 22 is movably connected to the groove.

[0081] Further reading Figure 13The tool base 2 also includes a locking part 24, which passes through at least a portion of the base body 23 and abuts against the movable part 22 to fix the relative position of the movable part 22 and the base body 23. The locking part 24 is used to lock the relative position of the movable part 22 and the base body 23. Exemplarily, the locking part 24 can be a screw, threadedly connected to the base body 23. The locking part 24, which passes through the base body 23, can abut against the movable part 22. When the locking part 24 is screwed in, the locking part 24 abuts against the movable part 22, and the applied force increases, forming a greater frictional force, thereby fixing the movable part 22 to the base body 23.

[0082] Figure 14 This is another schematic diagram of the installation of the blade and blade base of the peeling device according to an embodiment of this application.

[0083] Further, please refer to Figure 14 The cutting section 31 includes multiple cutting segments 33, which are connected sequentially along the first direction A1. Adjacent cutting segments 33 are provided with weakening structures 34. During the peeling operation, the area of ​​wear on the tool 3 is mainly concentrated in the part where the tool 3 extends between the flexible circuit board and the glass substrate, that is, a certain area at the end of the cutting section 31 away from the mounting section 32. In this embodiment, the cutting section 31 of the tool 3 includes multiple cutting segments 33, and the worn portion is mainly concentrated in the cutting segment 33 of the mounting section 32. The multiple cutting segments 33 form a whole, and the two ends along the second direction A2 are the first cutting edge 311 and the second cutting edge 312. When the portion of the cutting segment 33 away from the mounting section 32 corresponding to the first cutting edge 311 and the second cutting edge 312 has been significantly worn, the cutting segment 33 can be removed from the tool 3. At this time, the portion of the cutting segment 33 away from the mounting section 32 corresponding to the first cutting edge 311 and the second cutting edge 312 on the tool 3 is not yet significantly worn, and the tool 3 can continue to be used without scrapping the entire tool 3. Therefore, in this embodiment, the first cutting edge 311 and the second cutting edge 312 can be utilized more fully, the service life of the tool 3 can be further extended, and the consumption of the tool 3 is further reduced during continuous peeling operations, thus lowering operating costs. For example, when the tool 3 is provided with four cutting sections 33, the service life of the tool 3 during continuous peeling operations is close to eight times that of the tool 3 in related technologies.

[0084] After a cutting segment 33 is removed from the tool 3, the length of the cutting portion 31 of the tool 3 extending relative to the base body 23 becomes shorter. At this time, the movable part 22 is moved along the first direction A1, causing the tool 3 to move relative to the base body 23 along the first direction A1, thereby making the length of the cutting portion 31 of the tool 3 extending relative to the base body 23 consistent with that before the cutting segment 33 was removed from the tool 3, reducing the impact of removing the cutting segment 33 on the operational accuracy of continuous peeling operations.

[0085] The weakening structure 34 provided between the cutting sections 33 makes it easier to remove the worn cutting sections 33 from the tool 3. For example, the weakening structure 34 can be a groove that forms the cutting portion of the tool 3, so that the structural strength at the weakening structure 34 of the tool 3 is reduced, thereby removing the worn cutting section 33 from the tool 3 by means of breaking, cutting or shearing, etc.

[0086] Figure 15 This is a schematic flowchart of a stripping method according to an embodiment of this application.

[0087] Please see Figure 15 This application also provides a stripping method using the stripping device described in the foregoing embodiments of this application.

[0088] The peeling method in this application includes:

[0089] Continue reading Figure 15 Step S1: Install the cutting tool 3.

[0090] The mounting portion 32 of the cutting tool 3 is inserted into the mounting groove 21 of the cutting tool base 2 to connect the cutting tool 3 and the cutting tool base 2. When the positioning notch 323 of the first edge abuts against the positioning portion 211, the cutting tool 3 is installed in place, and the cutting tool 3 and the cutting tool base 2 can be fixed. For example, the cutting tool 3 and the cutting tool base 2 can be fixed together by fasteners 4.

[0091] Continue reading Figure 15 Step S2: Adjust the position of the stripping drive mechanism 1.

[0092] The peeling drive mechanism 1 is moved along the first direction A1, so that the tool base 2 and the tool 3 move together along the first direction A1, and at least a portion of the cutting part 31 of the tool 3 is inserted between the flexible display panel and the glass substrate.

[0093] Continue reading Figure 15 Step S3, single peeling.

[0094] The peeling drive mechanism 1 drives the tool base 2 to move along the second direction A2, so that the tool 3 moves along the second direction A2. The first cutting edge 311 of the tool 3 separates the flexible display panel and the glass substrate, realizing a single peeling operation.

[0095] Continue reading Figure 15 Step S4: Continuous peeling.

[0096] Repeat step S3 until the wear deformation of the first cutting edge 311 is greater than or equal to the scrap deformation, that is, the wear of the first cutting edge 311 has reached a level that will affect the stripping operation.

[0097] Continue reading Figure 15 Step S5: Reinstall tool 3.

[0098] Remove the cutting tool 3 from the cutting tool base 2, rotate the cutting tool 3 180°, and then reinstall the cutting tool 3 and the cutting tool base 2. When the positioning notch 323 on the edge of the cutting tool abuts against the positioning part 211, the cutting tool 3 is installed in place again, and the cutting tool 3 and the cutting tool base 2 can be fixed. For example, the cutting tool 3 and the cutting tool base 2 can be fixed together by fastener 4.

[0099] Continue reading Figure 15 Step S6: Continue peeling.

[0100] Repeat steps S2 and S3. The second cutting edge 312 of the tool 3 separates the flexible display panel and the glass substrate, and the peeling operation continues. When the wear deformation of the second cutting edge 312 is greater than or equal to the scrap deformation, the wear of the second cutting edge 312 has reached a level that will affect the peeling operation, and a new tool 3 is replaced.

[0101] In this embodiment, since both the first cutting edge 311 and the second cutting edge 312 of the tool 3 can be used to peel off the flexible display panel and the glass substrate, the tool 3 can be used more fully, thereby extending the service life of the tool 3. In the continuous peeling operation, the number of tools 3 consumed is reduced, thereby reducing the cost of the continuous peeling operation.

[0102] Figure 16 This is a schematic diagram of the structure of a cutting tool according to an embodiment of this application.

[0103] Please see Figure 16 This application also provides a cutting tool 3. The cutting tool 3 of this application is used in the peeling device of the foregoing embodiments of this application.

[0104] In summary, this application provides a peeling device, a peeling method, and a cutting tool. In the peeling device, the peeling drive mechanism is movable along a first direction and can also drive the cutting tool base to move along a second direction. This causes the cutting tool base and the cutting tool connected to the base to move along the first and / or second directions. The mounting portion of the cutting tool is inserted into the mounting groove of the cutting tool base. The positioning notch of either the first or second positioning edge of the cutting tool abuts against the positioning portion in the mounting groove, fixing the relative position of the cutting tool and the cutting tool base. During the use of the peeling device of this application, when the first cutting edge of the cutting portion is worn, the cutting tool can be flipped. At this time, the positioning notch of the other positioning edge abuts against the positioning portion in the mounting groove, fixing the relative position of the cutting tool and the cutting tool base. The second cutting edge can then be used to peel the flexible display panel and the glass substrate. In this application embodiment, both the first and second cutting edges of the cutting tool can be used to peel the flexible display panel and the glass substrate, allowing for more efficient use of the cutting tool, extending its service life, and reducing the number of cutting tools consumed and lowering operating costs during continuous peeling operations of flexible display panels and glass substrates.

[0105] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
