Description

Technical Field

[0001] The present application relates to the technical field of screen lamination, and in particular to a screen flip lamination jig and a screen flip lamination method. Background Art

[0002] In the field of TP (touch panel) and LCM (display screen) lamination processing, with the enrichment of application scenarios, different requirements are put forward for the full lamination technology of touch display, especially in the lamination of curved surface to flat surface, curved surface to curved surface and flat surface to flat surface, high-precision lamination technology is required to ensure the display effect.

[0003] However, the structural characteristics of the display screen, especially its flatness structure, have a significant impact on the bonding process with the touch panel. Specifically, large-size display screens are usually assembled by stacking multiple layers of materials such as liquid crystal display glass, polarizer (POL), diffusion film, light enhancement film, light guide plate, and backlight protection aluminum plate. This multi-layer structure leads to large differences in the flatness of the display screen, especially when the product size increases, the flatness problem becomes more prominent.

[0004] At present, the industry mainly adopts the liquid glue injection method for large-size full bonding. Although liquid glue has a certain degree of flexibility, due to the restriction of the flatness uniformity of the display screen during its injection process, there is often a problem of thickness difference between the display screen and the touch panel after bonding. This thickness difference will cause the display effects of different thickness areas to be different after the whole machine is assembled, which cannot meet the high requirements of display uniformity. In addition, due to the fluidity of liquid glue, bubbles are easily introduced during the bonding process, resulting in poor bonding; at the same time, the curing process of liquid glue may also cause uneven display such as yellowing, blackening or bluing of the display screen, affecting the display effect of the product and reducing the user experience.

[0005] In summary, the existing bonding technology has problems such as large flatness differences and uneven display effects when dealing with large-size display screens with high flatness requirements. Summary of the invention

[0006] Based on this, it is necessary to provide a screen flip bonding fixture to address the problems of large flatness differences and uneven display effects in existing screen bonding.

[0008] A first laminating component, used for placing a touch panel;

[0009] A second laminating assembly includes a mounting chamber for placing a display screen;

[0010] The second bonding component also includes a first supporting portion and a second supporting portion respectively arranged on the outer periphery of the installation chamber. When the second bonding component and the first bonding component are stacked, there is a gap between the second supporting portion and the first bonding component. The first supporting portion supports the first bonding component, and the second supporting portion supports the touch panel.

[0011] In one embodiment, the installation chamber is disposed on the surface of the second bonding component, and the first supporting portion and the second supporting portion are respectively spaced apart and disposed at the outer periphery of the installation chamber; the first supporting portion is higher than the second supporting portion.

[0012] In one embodiment, the first fitting assembly includes a first plate body, and the second fitting assembly includes a second plate body; the installation chamber is disposed in the middle area of ​​the second plate body;

[0013] The surface of the first plate body close to the installation cavity is used to place the touch panel; one end of the second support portion is arranged on the same side of the second plate body as the installation cavity, and the other end is used to abut against the surface of the touch panel.

[0014] In one embodiment, one end of the first support portion and the installation chamber are disposed on a surface of the same side of the second plate body, and the other end of the first support portion abuts against a surface of the first plate body on a side close to the second plate body.

[0015] In one of the embodiments, it further includes a plurality of the first supporting portions, which are respectively arranged at intervals on the outer periphery of the installation chamber; the first supporting portion is a protrusion on the surface of the second plate body on one side close to the first plate body.

[0016] In one embodiment, it also includes a plurality of second support portions, which are respectively arranged at intervals on the outer periphery of the installation chamber and have a distance from the first support portion; the second support portion is formed by a surface of the second plate body protruding outward on one side close to the first plate body, and there is a gap between the first support portion and the first plate body.

[0017] In one embodiment, the extension area of ​​the first plate body is consistent with the extension area of ​​the second plate body; the installation chamber is formed by an inward depression of the surface of the second plate body close to the first plate body.

[0018] In one embodiment, it also includes a locking component for snapping and connecting the first fitting component and the second fitting component, wherein a portion of the locking component is disposed on the outer side of the first fitting component, and another portion is correspondingly disposed on the outer side of the second fitting component.

[0019] The above-mentioned screen flipping and bonding jig ensures the stability of the first bonding component and the second bonding component when they are bonded, prevents the movement of the two, avoids problems such as uneven display after bonding or bubbles during bonding due to external forces, and improves the screen bonding effect.

[0020] According to another object of the present invention, a screen flipping and laminating method is also provided, which is applied to the above-mentioned screen flipping and laminating jig, and comprises the following steps:

[0021] S1, placing the display screen in the installation chamber of the second bonding component;

[0023] S3, applying a glue layer to the surface of the touch panel facing the display screen;

[0024] S4, pressing the first laminating component onto the second laminating component;

[0025] S5. Flip the first bonding component and the second bonding component 180 degrees as a whole, so that the second bonding component is pressed on the first bonding component and pressed downward on the first bonding component by the gravity of the second bonding component and the display screen.

[0026] In one embodiment, in step S4, pressing the first bonding component onto the second bonding component includes: making the first supporting portion abut against the first bonding component for support, and making the second supporting portion abut against the touch panel for support.

[0027] The above screen flipping and laminating method, by utilizing the laminating method of the second laminating component pressing down by its own weight, effectively reduces the display unevenness problem caused by external force factors and flatness factors of the display screen, and improves the overall quality of the product. In addition, the process production process is short, which is conducive to improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0038] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0039] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0040] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0041] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0042] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0043] At present, the technology that is closest to flat-to-flat full bonding in the full bonding process industry is the liquid water glue bonding method. There are two main methods: one is to apply glue on the touch panel or display screen first, and then bond; the other is to first use a specific structure of adhesive to frame the touch panel and the four sides of the display screen, and then fill the bonding cavity with glue. However, these existing technologies still rely on traditional bonding methods, such as applying double-sided tape or applying RTV glue to fix the distance between TP and LCM, and then injecting glue to fill. These methods cannot fundamentally solve the bonding problem caused by the difference in the flatness of the display screen.

[0044] See also Figure 1 , Figure 1A schematic diagram of the structure of a screen flipping and laminating jig in an embodiment of the present application is shown. A screen flipping and laminating jig provided in an embodiment of the present application includes a first laminating component 1 and a second laminating component 2. The first laminating component 1 is used to place a touch panel 3. The second laminating component 2 includes an installation chamber 20, a first support portion 22 and a second support portion 23, and the installation chamber 20 is used to place a display screen 4. The first support portion 22 and the second support portion 23 are respectively arranged on the periphery of the installation chamber 20, and the first support portion 22 supports the first laminating component 1. When the second laminating component 2 and the first laminating component 1 are stacked, there is a gap between the second support portion 23 and the first laminating component 1, and the gap is used to place the touch panel 3, and the second support portion 23 supports the touch panel 3.

[0045] As described above, by setting the first support part 22 to abut against the first bonding component 1 for support, and the second support part 23 to abut against the touch panel 3 placed on the first bonding component 1 for support, when the first bonding component 1 and the second bonding component 2 are bonded, the first support part 22 and the second support part 23 can play a role of stable support to prevent the first bonding component 1 or the touch panel 3 from moving, avoid problems such as poor bonding effect due to external force factors, improve the stability of the screen during bonding, and improve the bonding effect.

[0046] In one embodiment, the first bonding component 1 is configured as a flat bearing platform to ensure that the flatness meets the requirements. The surface of the first bonding component 1 facing the mounting chamber 20 is used to place the touch panel 3. The bonding surface of the touch panel 3, that is, the side in contact with the display screen 4, is pre-evenly coated with a layer of TOCA adhesive layer before bonding. The selection of the TOCA adhesive layer needs to consider the bonding effect and optical transparency.

[0047] In one embodiment, the second laminating component 2 is provided with an installation chamber 20, and the installation chamber 20 is used to place the display screen 4. The shape and size of the installation chamber 20 match the display screen 4, ensuring that the display screen 4 can be placed firmly and will not affect the laminating effect due to shaking or misalignment. The side of the second laminating component 2 that contacts the first laminating component 1 needs to maintain a high degree of flatness so as to provide uniform pressure distribution during the laminating process.

[0048] In one embodiment, the first supporting portion 22 and the second supporting portion 23 are respectively disposed at intervals on the outer periphery of the installation chamber 20 .

[0049] Specifically, the installation chamber 20 is arranged on the surface of the second bonding component 2 close to the first bonding component 1. The first support portion 22 is arranged on the periphery of the installation chamber 20, and the second support portion 23 is also arranged on the periphery of the installation chamber 20, and the first support portion 22 and the second support portion 23 are arranged at an interval. On the premise of ensuring the supporting functionality of the first support portion 22 and the second support portion 23, the compact structural layout of the two is optimized to effectively control the volume of the fixture.

[0050] Furthermore, the first supporting portion 22 is higher than the second supporting portion 23 , so that the first supporting portion 22 can abut against the first bonding component 1 , and a gap is left between the second supporting portion 23 and the first bonding component 1 for placing the touch panel 3 .

[0051] In the specific implementation process, after the first bonding component 1 and the second bonding component 2 are bonded, the first bonding component 1 and the second bonding component 2 are flipped over so that the second bonding component 2 is pressed on top of the first bonding component 1, so that the second bonding component 2 can press the first bonding component 1 downward by its own weight for bonding. By utilizing the second bonding component 2's own weight to press the first bonding component 1 downward, efficient and uniform bonding between the touch panel 3 and the display screen 4 is achieved, avoiding problems such as uneven pressure and bubbles that may occur in the traditional bonding process. The bonding method after flipping allows the LCD screen glass surface of the display screen 4 to form a flat contact with the touch panel 3, effectively reducing the uneven display problem caused by the unevenness of the display screen 4.

[0052] Combination Figure 4 As shown, Figure 4 1 is a schematic diagram of the structure of a first bonding component 1 provided in an embodiment of the present application. In some embodiments, the first bonding component 1 includes a first plate body 11.

[0053] Specifically, the first plate body 11 is a main body of the first bonding component 1 and is configured as a flat plate structure. The first plate body 11 is preferably made of metal or high-strength plastic material to ensure its rigidity and stability. The surface of the first plate body 11 close to the installation chamber 20 is used to place the touch panel 3, providing a location for the installation of the touch panel 3.

[0054] Combination Figure 2 As shown, Figure 2 Schematic diagram of the structure of the second laminating assembly 2 provided in an embodiment of the present application. In some embodiments, the second laminating assembly 2 includes a second plate body 21 , and the installation chamber 20 is disposed in the middle area of ​​the second plate body 21 .

[0055] Specifically, the second plate body 21, as the main body of the second bonding component 2, is set as a flat plate structure, preferably made of metal or high-strength plastic material to ensure its rigidity and stability. An inwardly recessed mounting chamber 20 is set in the middle area of ​​the second plate body 21. The shape and size of the mounting chamber 20 match the display screen 4 and are used to accommodate the display screen 4 and fix its position. The display surface of the display screen 4 faces the opening direction of the mounting chamber 20 to facilitate subsequent bonding with the touch panel 3.

[0056] Furthermore, the extension area of ​​the first plate body 11 is consistent with the extension area of ​​the second plate body 21, ensuring that the first bonding component 1 and the second bonding component 2 can completely correspond to each other during the bonding process, thereby achieving precise bonding.

[0057] Combination Figure 3 As shown, Figure 3 Schematic diagram of the structure of the second bonding assembly 2 provided in an embodiment of the present application. In some embodiments, one end of the second support portion 23 and the mounting chamber 20 are disposed on the surface of the second plate 21 on the same side, and the other end is used to abut against the surface of the touch panel 3.

[0058] Specifically, the surface of the first plate body 11 close to the second plate body 21 is used to place the touch panel 3. The second support portion 23 is arranged on the surface of the second plate body 21 close to the first plate body 11, that is, it is arranged on the same side of the second plate body 21 as the installation chamber 20. One end of the second support portion 23 is connected to the surface of the second plate body 21, and the other end is in contact with the surface of the touch panel 3 on the first plate body 11, so as to ensure that the touch panel 3 and the display screen 4 can maintain stable contact during the flipping and bonding process, and prevent the touch panel 3 from being damaged by excessive pressure.

[0059] In one embodiment, one end of the first support portion 22 and the installation chamber 20 are disposed on the surface of the same side of the second plate body 21 , and the other end of the first support portion 22 abuts against the surface of the first plate body 11 close to the second plate body 21 .

[0060] Specifically, one end of the first support portion 22 is arranged on the surface of the same side of the second plate body 21 as the installation chamber 20, that is, the first support portion 22 is arranged in the edge area of ​​the outer periphery of the installation chamber 20, and the other end of the first support portion 22 abuts against the surface of the first plate body 11 on the side close to the second plate body 21 to ensure that the pressure between the touch panel 3 and the display screen 4 is evenly distributed during the bonding process, while avoiding direct contact between the first plate body 11 and the second plate body 21.

[0061] In one embodiment, the second fitting component 2 further includes a plurality of the first supporting portions 22 , and the plurality of the first supporting portions 22 are respectively arranged at intervals on the outer periphery of the installation chamber 20 .

[0062] Specifically, on the surface of the second plate body 21 close to the first plate body 11, a plurality of first support portions 22 are arranged at intervals around the outer circumference of the installation chamber 20, that is, there is a certain distance between the plurality of first support portions 22, which helps to improve the uniformity of the supporting force between the first support portions 22 and the first plate body 11.

[0063] Further, the first supporting portion 22 is a protrusion on the surface of the second plate body 21 close to the first plate body 11 .

[0064] Specifically, the first support portion 22 is a structure protruding outward from the surface of the second plate body 21, and is used to provide stable support during the bonding process and prevent scratches or damages caused by direct contact between the first bonding component 1 and the second bonding component 2.

[0065] In one embodiment, the number, shape and position of the first support parts 22 can be adjusted according to the size, shape and bonding requirements of the display screen 4 and the touch panel 3. The first support parts 22 are arranged in a columnar shape and are evenly distributed around the periphery of the mounting chamber 20 to ensure that the pressure between the touch panel 3 and the display screen 4 is evenly distributed during the bonding process to avoid problems caused by excessive local pressure.

[0066] Combination Figure 5 As shown, Figure 5 Schematic diagram of the front view of the screen flipping and laminating jig provided in one embodiment of the present application. In some embodiments, the second laminating component 2 further includes a plurality of second supporting portions 23. The plurality of second supporting portions 23 are respectively arranged at intervals on the periphery of the mounting chamber 20, and are spaced apart from the first supporting portion 22.

[0067] Specifically, a plurality of second support portions 23 are arranged at intervals in the peripheral area of ​​the mounting chamber 20 to ensure that uniform support force can be obtained between the touch panel 3 and the display screen 4 in the entire bonding area. There is a distance between the second support portion 23 and the first support portion 22, in order to effectively optimize the overall structure of the fixture and control the volume of the fixture while ensuring the supporting performance.

[0068] In one embodiment, the second supporting portion 23 is formed by a surface of the second plate body 21 close to the first plate body 11 protruding outward, and a gap exists between the first supporting portion 22 and the first plate body 11 .

[0069] Specifically, the second support portion 23 is formed by a columnar structure protruding outward from the surface of the second plate body 21 close to the first plate body 11, and is used to support the touch panel 3. There is a gap between the first support portion 22 and the first plate body 11, which helps to provide necessary buffer space during the flipping and laminating process to prevent damage caused by excessive contact.

[0070] As described above, by providing the installation chamber 20, the first support portion 22 and the second support portion 23, accurate alignment and uniform bonding between the display screen 4 and the touch panel 3 are ensured, reducing the error and defect rate during the bonding process. The provision of the first support portion 22 and the second support portion 23 effectively prevents direct contact between the first bonding component 1 and the second bonding component 2, avoiding the risk of scratching or damaging the screen.

[0071] Combination Figure 1 As shown, Figure 1 Schematic diagram of the structure of the screen flipping and laminating jig provided in an embodiment of the present application. In some embodiments, the first plate 11 is provided with a plurality of through holes 12 therethrough.

[0072] Specifically, the plurality of through holes 12 are evenly spaced along the length direction or width direction of the first plate body 11, which significantly reduces the overall weight of the first bonding component 1 and reduces the manufacturing difficulty and cost. The number and distribution of the through holes 12 are adaptively adjusted according to specific bonding requirements. The through holes 12 are set to be circular, while ensuring that the overall strength and stability of the first plate body 11 are not affected.

[0073] In one embodiment, the screen flipping and laminating jig further includes a locking component 5, and the locking component 5 is used to buckle and connect the first laminating component 1 and the second laminating component 2.

[0074] Specifically, a portion of the locking component 5 is disposed outside the first bonding component 1, and another portion is correspondingly disposed outside the second bonding component 2. When the first bonding component 1 is pressed against the second bonding component 2, the two portions of the locking component 5 can be mutually buckled, thereby locking the connection between the two.

[0075] In this embodiment, the locking component 5 is composed of two hooks, which are respectively arranged on the outside of the first bonding component 1 and the second bonding component 2. When the first bonding component 1 is pressed on the second bonding component 2, the two hooks can be hooked together, thereby locking the connection between the two and improving the stability of the bonding.

[0076] Combination Figure 6 As shown, Figure 6 A screen flipping and laminating method applied to the above-mentioned screen flipping and laminating jig provided in one embodiment of the present application includes the following steps:

[0077] S1, placing the display screen 4 in the installation chamber 20 of the second bonding component 2;

[0078] S2, placing the touch panel 3 on the surface of the first bonding component 1 facing the installation chamber 20;

[0079] S3, applying the adhesive layer to the surface of the touch panel 3 facing the display screen 4;

[0080] S4, pressing the first laminating component 1 onto the second laminating component 2;

[0081] S5. Flip the first bonding component 1 and the second bonding component 2 by 180 degrees as a whole, so that the second bonding component 2 is pressed on the first bonding component 1, and is pressed downward on the first bonding component 1 by the gravity of the second bonding component 2 and the display screen 4.

[0082] In the specific implementation process, the display screen 4 is first placed in the installation chamber 20 of the second bonding component 2, and the display surface of the display screen 4, that is, the side of the display screen 4 that contacts the touch panel 3, faces the opening direction of the installation chamber 20. Then the touch panel 3 is installed at a predetermined position of the first bonding component 1, and the TOCA adhesive layer is evenly covered on the bonding surface of the touch panel 3. Then the first bonding component 1 and the second bonding component 2 are aligned face to face, and the first bonding component 1 is pressed on the second bonding component 2.

[0083] Furthermore, the entire jig is slowly and steadily turned over 180 degrees, so that the second bonding component 2 is above the first bonding component 1, so that the second bonding component 2 and the display screen 4 can be naturally pressed toward the first bonding component 1 due to gravity. Then, the jig is placed in the vacuum environment of the sealed cavity, and the weight of the second bonding component 2 is gradually applied to the TOCA adhesive layer, causing it to begin to soften and form a preliminary contact with the surface of the display screen 4. Since the LCD screen glass surface in the display screen 4 is relatively flat, the flat-to-flat contact bonding method after flipping can effectively solve the problem of uneven display caused by uneven force during the lamination process due to the unevenness of the display screen 4.

[0084] Furthermore, the TOCA adhesive layer further spreads under pressure and closely adheres to the surface of the display screen 4 to promote complete curing of the adhesive layer. By using the laminating method of the second laminating component 2 pressing down under its own weight, the pressure of the external force of the device on the surface of the display screen 4 is reduced, and the display unevenness problem of the display screen 4 caused by external force factors is further reduced.

[0085] As described above, by utilizing the lamination method of the second laminating component 2 pressing down by its own weight and the flat contact lamination of the liquid crystal screen glass surface in the flipped display screen 4, the display unevenness problem of the display screen 4 caused by external force factors and flatness factors is effectively reduced, and the overall quality of the product is improved. In addition, the process has a short production process, high efficiency, and does not require additional pressure equipment or complex operations, and has low investment costs, which is conducive to reducing production costs and improving production efficiency.

[0086] In one of the embodiments, in step S4, pressing the first bonding component 1 onto the second bonding component 2 includes: making the first support portion 22 abut against the first bonding component 1 for support, and making the second support portion 23 abut against the touch panel 3 for support, thereby improving the stability of the first bonding component 1 and the second bonding component 2 during the bonding process, preventing the two from moving, avoiding uneven bonding due to external forces, and improving the bonding effect.

[0087] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
