Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a full-lamination device and method for a display screen. Background Art

[0002] During the production of display screens, a full bonding process is required. This involves completely filling the gaps between the screens with a transparent adhesive layer. This process aims to eliminate the air layer between the rigid screens, thereby reducing reflections from the air layer and improving the contrast and viewing experience of the display in bright environments.

[0003] Currently, the full lamination process for display screens is typically performed by a laminating machine to remove air from between rigid screens. However, existing laminating machines, such as those described in the Chinese utility model patent application "A Laminating Machine" with authorization publication number CN221417659U, perform alignment and laminating operations only after each set of rigid screens (each set of rigid screens includes a first screen and a second screen in corresponding positions) are placed into a vacuum chamber, resulting in very low production efficiency. This is particularly true when laminating batches of rigid screens, as each lamination requires vacuuming before the operation, making it difficult to meet mass production requirements. Furthermore, when the first screen consists of two or more panels and requires 2-to-1 or N-to-1 lamination, production efficiency is even lower. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a display screen full bonding device and bonding method, which can achieve bubble-free full bonding between the first screen body and the second screen body, reduce process difficulty, and significantly improve production efficiency. The technical solution adopted is as follows: A full-fitting device for a display screen includes a positioning plate, characterized in that: an upper positioning area and a lower positioning area are provided on the positioning plate, the lower positioning area is below the upper positioning area and within the range of the upper positioning area, the upper positioning area includes at least one first screen body positioning area, and the lower positioning area includes a second screen body positioning area; the full-fitting device for the display screen also includes an upper cover and a plurality of magnetic adsorption pairs, the upper cover is detachably mounted on the positioning plate and is located on the upper side of the upper positioning area; each magnetic adsorption pair includes a fixed magnetic part and a movable magnetic part that attract each other, the fixed magnetic part is fixedly mounted on the corresponding position of the upper cover, and the movable magnetic part is movably arranged on the lower side of the lower positioning area and corresponds to the position of the fixed magnetic part; a guiding mechanism that can guide each movable magnetic part is provided between the positioning plate and the lower positioning area.

[0005] In a display screen, the first screen body is generally a protective lens (also called a cover plate, LENS) that constitutes a display module, and the second screen body is generally a display device (especially an LCD screen with or without a backlight), a touch screen and other components.

[0006] In the above display full lamination device, the first screen positioning area is used to place and position the first screen, and the second screen positioning area is used to place and position the second screen, so as to achieve the mutual alignment of the first screen and the second screen. After the first screen and the second screen are respectively placed in the first screen positioning area and the second screen positioning area, there is a gap between the first screen and the second screen; A glue layer, such as an optical transparent glue layer (OCA glue), can be pre-applied to the surface of the first screen facing the second screen. When laminating, the display full lamination device is placed in a vacuum environment, and the magnetic field force generated by the fixed magnetic members of each magnetic adsorption pair is used to generate an adsorption force on the corresponding movable magnetic members through the first screen and the second screen respectively, and the guiding mechanism is used to drive each movable magnetic member to move upward to lift the second screen to displace towards the first screen, so that it is laminated with the first screen through the glue layer and the gap is eliminated, and finally the bubble-free full lamination of the first screen and the second screen is achieved.

[0007] The positioning disk can be made of materials such as metal, bakelite, plastic or wood. To ensure the positioning accuracy, as a preferred solution of the present invention, the positioning disk is carved from aluminum alloy or bakelite.

[0008] The upper cover can be a plate body or other support structures for installing the fixed magnetic members, such as a support net or a support frame. To enable the upper cover to be stably installed on the positioning disk, the positioning disk can be provided with an upper cover positioning groove for positioning and placing the upper cover, or installed on the positioning disk by means of pins or the like to form a positioning.

[0009] As a preferred solution of the present invention, the positioning disk has an inner cavity, the first screen positioning area is a first screen positioning groove opened on the inner side wall of the positioning disk, and the second screen positioning area is a second screen positioning groove opened on the inner side wall of the positioning disk. Generally, the cross-sectional shape and size of the first screen positioning groove match the first screen, the cross-sectional shape and size of the second screen positioning groove match the second screen, and the depth of the second screen positioning groove is slightly greater than the thickness of the second screen, so that after the first screen and the second screen are respectively placed in the first screen positioning groove and the second screen positioning groove, there is a gap between the first screen and the second screen.

[0010] Since the second screen generally completely shields the first screen, the second screen positioning groove is generally a second-order screen positioning groove at the bottom of the first screen positioning groove (that is, the second screen positioning groove is completely within the range of the first screen positioning groove). As a further preferred solution of the present invention, an annular limiting step is formed between the first screen positioning groove and the second screen positioning groove.

[0011] As a further preferred solution of the present invention, the depth of the second screen positioning groove is 1.5 mm to 10 mm.

[0012] As a further preferred embodiment of the present invention, the guide mechanism includes a plurality of guide holes and a plurality of push rods. The guide holes and push rods are equal in number and correspond one to one with the movable magnetic elements. The guide holes are formed at the bottom of the second screen body positioning slot and extend vertically. The upper ends of the push rods are connected to the lower surface of the movable magnetic element, and the lower portions of the push rods are located in the guide holes. Thus, the cooperation between the guide holes and the push rods can be used to guide the movable magnetic elements.

[0013] As a further preferred embodiment of the present invention, the positioning plate is provided with an exhaust channel, the inner end of which communicates with the top of the second screen positioning groove, and the outer end of which communicates with the exterior of the positioning plate. After the first and second screens are placed in the first and second screen positioning grooves, respectively, a gap is formed between the first and second screens, which communicates with the exterior of the positioning plate via the exhaust channel. This allows the display screen lamination device to be placed in a vacuum chamber and evacuated, allowing gas in the gap to be efficiently extracted.

[0014] Since the movable magnetic part is the movable part and the fixed magnetic part is the non-moving part during the mutual adsorption process between the fixed magnetic part and the movable magnetic part, in order to facilitate installation and operation, the fixed magnetic part can adopt an electromagnet with a more complex structure and requiring wire connection, and the movable magnetic part can be designed as a slider or a pressure part that can slide up and down, such as a metal block, a permanent magnet or a soft magnet.

[0015] As a preferred embodiment of the present invention, the fixed magnetic element is an electromagnet, and the movable magnetic element is a soft magnet. When the electromagnet is energized, it generates a magnetic field that transmits through the first and second screens to exert an attractive force on the soft magnet. When the electromagnet is de-energized, the magnetic field disappears, rendering it unable to exert an attractive force on the soft magnet. This allows for more convenient and efficient control of the magnetic field, simple and flexible operation, and easy adaptation to vacuum environments, reducing process complexity and significantly improving production efficiency.

[0016] As a further preferred embodiment of the present invention, the fixed magnetic parts of the plurality of magnetic adsorption pairs are distributed along the first horizontal direction, and the movable magnetic parts of the plurality of magnetic adsorption pairs are distributed along the first horizontal direction. The first horizontal direction distribution is parallel to the direction of the positioning plate surface, and is generally consistent with the length direction of the first screen body or the second screen body after placement. Specifically, the plurality of magnetic adsorption pairs are evenly arranged along the first horizontal direction, and each column of magnetic adsorption pairs has at least two magnetic adsorption pairs. For cases where the area of the screen body to be bonded is large, by setting a plurality of magnetic adsorption pairs at different positions, a pressing action can be generated at different positions of the display screen, thereby achieving effective bonding at various positions of the display screen.

[0017] As a further preferred embodiment of the present invention, a plurality of the magnetic adsorption pairs are divided into different magnetic adsorption groups. The magnetic adsorption pairs belonging to the same magnetic adsorption group are independently controlled by the same control circuit, and the magnetic adsorption pairs belonging to different magnetic adsorption groups are controlled by different control circuits. During the lamination process, the power-on time difference of different magnetic adsorption groups can be controlled by different control circuits, thereby controlling the lamination sequence of different positions of the display screen. By reasonably controlling the lamination sequence, the lamination of certain areas can be independently and flexibly controlled to meet the lamination requirements of the product, and at the same time, the residual lamination stress during lamination can be avoided.

[0018] The present invention also provides a lamination method, which is characterized by including the following steps: S1. Provide at least one of the display screen full lamination devices; S2. Place a first screen body and a second screen body in the first screen body positioning area and the second screen body positioning area of the display screen full lamination device respectively. There is a gap between the first screen body and the second screen body, and an adhesive layer is applied on the side of the first screen body facing the second screen body or the side of the second screen body facing the first screen body. S3. Transfer the display screen full lamination device into a closed cavity and evacuate the closed cavity to completely remove the residual gas in the gap, so that the display screen full lamination device is in a vacuum environment. S4. Perform a pressing operation on the first screen body and the second screen body on the display screen full lamination device in a vacuum environment. Utilize the magnetic adsorption force generated by the fixed magnetic components of each magnetic adsorption pair on the movable magnetic components, and cooperate with the guiding mechanism to drive each movable magnetic component to move upward to lift the second screen body to displace towards the first screen body, so that it is pressed and laminated with the first screen body through the adhesive layer to eliminate the gap, and finally achieve bubble-free full lamination of the first screen body and the second screen body.

[0019] This lamination method first realizes the alignment of the first screen body and the second screen body through the display screen full lamination device, then places the display screen full lamination device and the first screen body and the second screen body therein in a vacuum environment, and finally performs a pressing operation on the first screen body and the second screen body by using the magnetic adsorption force generated by each magnetic adsorption pair in the vacuum environment to achieve bubble-free full lamination between the first screen body and the second screen body. Since the alignment and full lamination processes of the screen bodies are completed step by step, the screen body alignment is operated in an atmospheric environment, and its operation environment is loose and the operation is more free. Moreover, the pressing operation is performed by using the magnetic adsorption force generated by each magnetic adsorption pair in a vacuum environment, and the operation is simple and flexible, and it is easy to adapt to the vacuum environment, reducing the process difficulty and greatly improving the production efficiency.

[0020] As a preferred embodiment of the present invention, in the step S1, in the provided display screen full lamination device, the fixed magnetic member of the magnetic adsorption pair is an electromagnet, and the movable magnetic member is a soft magnet; in the step S4, the electromagnets of each magnetic adsorption pair are energized, and the adsorption force generated by the electromagnet on the soft magnet is used to drive the soft magnet to rise to push the second screen body to displace towards the first screen body. Since only the driving wires need to penetrate into the vacuum chamber without involving complex mechanical structures, the equipment structure is simplified, space is saved, and costs are reduced. As a further preferred embodiment of the present invention, in the display screen full lamination device provided in the step S1, a plurality of the magnetic adsorption pairs are divided into different magnetic adsorption groups. The magnetic adsorption pairs belonging to the same magnetic adsorption group are independently controlled by the same control circuit, and the magnetic adsorption pairs belonging to different magnetic adsorption groups are controlled by different control circuits; in the step S4, by controlling the power-on time difference of different magnetic adsorption groups through different control circuits, the suction sequence of different positions of the first screen body and the second screen body is controlled, so as to achieve bubble-free full lamination of each position of the first screen body and the second screen body. For the case of a larger lamination screen area, by arranging a plurality of magnetic adsorption pairs at different positions, pressing actions can be generated at different positions of the display screen to achieve effective lamination of each position of the display screen. By reasonably controlling the suction sequence, the residue of lamination stress can be avoided.

[0021] As a further preferred embodiment of the present invention, in the step S4, the suction sequence of different positions of the first screen body and the second screen body is controlled as follows: by controlling the power-on time difference of different magnetic adsorption groups through different control circuits, first control the middle positions of the first screen body and the second screen body to be sucked together, and then control the two end positions of the first screen body and the two end positions of the second screen body to be sucked together.

[0022] As a preferred embodiment of the present invention, in the step S1, a plurality of the display screen full lamination devices are provided; in the step S3, the plurality of display screen full lamination devices are moved into the same closed cavity together. Thus, the parallel operation of multiple groups of display screen lamination processes can be realized, greatly improving the production efficiency.

[0023] As a further preferred embodiment of the present invention, in the step S3, first place the plurality of display screen full lamination devices horizontally and stack them vertically together, and then move these stacked display screen full lamination devices into the same closed cavity together. Thus, space can be saved to a greater extent, and the production efficiency can be greatly improved.

[0024] Compared with the prior art, the present invention has the following advantages: The full bonding device for display screens provided by the present invention can respectively place and position the first screen body and the second screen body through the first screen body positioning area and the second screen body positioning area to achieve the alignment of the first screen body and the second screen body, and then use the magnetic attraction force generated by each magnetic adsorption pair to perform a pressing operation on the first screen body and the second screen body in a vacuum environment, so as to achieve bubble-free full bonding between the first screen body and the second screen body without involving large-scale equipment. In addition, the alignment and full bonding process of the first screen body and the second screen body are completed in steps, and the screen alignment is performed in an atmospheric environment. The operating environment is relaxed and the operation is freer. In addition, the pressing operation is performed by using the magnetic attraction force generated by each magnetic adsorption pair in a vacuum environment. The operation is simple and flexible, and it is easy to adapt to the vacuum environment, which reduces the process difficulty and can greatly improve the production efficiency.

DETAILED DESCRIPTION

[0030] like Figures 1-2As shown, this full lamination device 100 for a display screen includes a positioning disk 1, an upper cover 2, and a plurality of magnetic adsorption pairs 3. The positioning disk 1 has an inner cavity 10, in which an upper positioning area 101 and a lower positioning area 102 are provided. The lower positioning area 102 is below the upper positioning area 101 and within the range of the upper positioning area 101. The upper positioning area 101 includes at least one first screen body positioning area, and the lower positioning area 102 includes a second screen body positioning area. The first screen body positioning area is a first screen body positioning groove 1011 formed on the inner side wall of the positioning disk 1, and the second screen body positioning area is a second screen body positioning groove 1021 formed on the inner side wall of the positioning disk 1. The upper cover 2 is detachably installed on the positioning disk 1 and is located above the upper positioning area 101. Each magnetic adsorption pair 3 includes a fixed magnetic attracting member 31 and a movable magnetic attracting member 32 that attract each other. The fixed magnetic attracting member 31 is fixedly installed at a corresponding position on the upper cover 2, and the movable magnetic attracting member 32 is movably arranged below the lower positioning area 102 and corresponds to the position of the fixed magnetic attracting member 31. A guiding mechanism 11 capable of guiding each movable magnetic attracting member 32 is provided between the positioning disk 1 and the lower positioning area 102.

[0031] In this embodiment, the positioning disk 1 is made of aluminum alloy or bakelite by carving, so as to ensure the positioning accuracy. The upper cover 2 is a plate body for installing the fixed magnetic attracting member 31. In order to enable the upper cover 2 to be stably installed on the positioning disk 1, the upper cover 2 is installed on the upper side of the positioning disk 1 by positioning pins 21.

[0032] In this embodiment, the second screen body positioning groove 1021 is a two-stage screen body positioning groove at the bottom of the first screen body positioning groove 1011 (that is, the second screen body positioning groove 1021 is completely within the range of the first screen body positioning groove 1011). The depth of the second screen body positioning groove 1021 is 1.5 mm to 10 mm. An annular limiting step 1012 is formed between the first screen body positioning groove 1011 and the second screen body positioning groove 1021. The cross-sectional shape and size of the first screen body positioning groove 1011 match those of the first screen body 200, and the cross-sectional shape and size of the second screen body positioning groove 1021 match those of the second screen body 300. And the depth of the second screen body positioning groove 1021 is slightly greater than the thickness of the second screen body 300, so that after the first screen body 200 and the second screen body 300 are respectively placed in the first screen body positioning groove 1011 and the second screen body positioning groove 1021, a gap 201 exists between the first screen body 200 and the second screen body 300.

[0033] In this embodiment, the guiding mechanism 11 includes a plurality of guiding holes 111 and a plurality of ejector rods 112. The number of guiding holes 111, ejector rods 112 is the same as that of the movable magnetic attracting members 32 and they correspond one by one. The guiding holes 111 are opened at the bottom of the second screen body positioning groove 1021 and are in the up-and-down direction. The upper end of the ejector rod 112 is connected to the lower surface of the movable magnetic attracting member 32, and the lower part of the ejector rod 112 is located in the guiding hole 111.

[0034] In this embodiment, an exhaust channel 103 is provided on the positioning plate 1. The inner end of the exhaust channel 103 communicates with the top of the second screen positioning groove 1021, and the outer end of the exhaust channel 103 communicates with the exterior of the positioning plate 1. After the first screen 200 and the second screen 300 are placed in the first screen positioning groove 1011 and the second screen positioning groove 1021, respectively, a gap 201 is formed between the first screen 200 and the second screen 300, which communicates with the exterior of the positioning plate 1 through the exhaust channel 103. This allows the gas in the gap 201 to be efficiently exhausted when the display screen lamination device 100 is placed in a vacuum chamber and a vacuum is drawn.

[0035] In this embodiment, the fixed magnetic element 31 is an electromagnet, and the movable magnetic element 32 is a soft magnet. When the electromagnet is energized, it generates a magnetic field that transmits through the first and second screens 200 and 300 to exert an attractive force on the soft magnet. When the electromagnet is de-energized, the magnetic field disappears, rendering it unable to exert an attractive force on the soft magnet. This allows for more convenient and efficient control of the magnetic field, simple and flexible operation, and easy adaptation to vacuum environments, reducing process complexity and significantly improving production efficiency.

[0036] In this embodiment, the fixed magnetic elements 31 of the multiple magnetic adsorption pairs 3 are distributed along a first horizontal direction, while the movable magnetic elements 32 of the multiple magnetic adsorption pairs 3 are distributed along the first horizontal direction. The first horizontal direction is parallel to the surface of the positioning plate 1 and coincides with the length of the first screen 200 or second screen 300 after placement. For applications involving larger screen areas, multiple magnetic adsorption pairs 3 positioned in different locations can be used to generate a pressing action at different locations on the display screen, achieving effective bonding at all locations.

[0037] In this embodiment, the multiple magnetic adsorption pairs 3 are divided into different magnetic adsorption groups. The magnetic adsorption pairs 3 belonging to the same magnetic adsorption group are independently controlled by the same drive circuit 30, while the magnetic adsorption pairs 3 belonging to different magnetic adsorption groups are controlled by different drive circuits 30. During the bonding process, the power-on time difference of different magnetic adsorption groups can be controlled by different drive circuits 30, thereby controlling the order in which different positions of the display screen are bonded. By properly controlling the bonding order, the bonding of certain areas can be independently and flexibly controlled to meet the bonding requirements of the product and avoid residual bonding stress during bonding.

[0038] refer to Figures 3-5 The bonding method provided by the present invention comprises the following steps: S1. Provide multiple display screen full lamination devices 100; S2. Place the first screen 200 and the second screen 300 in the first screen positioning groove 1011 and the second screen positioning groove 1021 of each display screen full-lamination device 100, respectively. The first screen 200 is a protective lens constituting the display module, and the second screen 300 is a display device. A gap 201 is formed between the first screen 200 and the second screen 300. Apply a glue layer 301 on the side of the second screen 300 facing the first screen 200. S3. First, multiple display screen laminating devices 100 are placed horizontally and stacked vertically. Then, the stacked display screen laminating devices 100 are moved together into the same closed cavity 400. The closed cavity 400 is evacuated to completely remove the gas remaining in the gap 201 between the first screen body 200 and the second screen body 300, so that each display screen laminating device 100 is in a vacuum environment. S4. Perform a pressing operation on the first screen body 200 and the second screen body 300 on each display screen full-lamination device 100 in a vacuum environment. Utilize the magnetic attraction force generated by the fixed magnetic parts 31 of each magnetic attraction pair 3 on the movable magnetic parts 32, and cooperate with the guide mechanism 11 to drive each movable magnetic part 32 to move upward to lift the second screen body 300 and move it toward the first screen body 200, so that it is pressed with the first screen body 200 through the adhesive layer 301 and the gap 201 is eliminated, finally achieving bubble-free full lamination of the first screen body 200 and the second screen body 300.

[0039] In this embodiment, in step S1, in the provided display screen full lamination device 100, the fixed magnetic member 31 of the magnetic attraction pair 3 is an electromagnet, and the movable magnetic member 32 is a soft magnet; in step S4, each magnetically attracted electromagnet is energized, and the attraction force exerted by the electromagnet on the soft magnet is used to drive the soft magnet upward to lift the second screen 300 toward the first screen 200. Since the vacuum chamber only needs to be penetrated by the drive wire, and no complex mechanical structure is involved, the equipment structure is simplified, space is saved, and costs are reduced. In this embodiment, in the display screen full bonding device 100 provided in step S1, multiple magnetic adsorption pairs 3 are divided into different magnetic adsorption groups, the magnetic adsorption pairs 3 belonging to the same magnetic adsorption group are independently controlled by the same driving circuit 30, and the magnetic adsorption pairs 3 belonging to different magnetic adsorption groups are controlled by different driving circuits 30; in step S4, the power-on time difference of different magnetic adsorption groups is controlled by different driving circuits 30 to control the attraction order of different positions of the first screen body 200 and the second screen body 300: first, the middle position of the first screen body 200 is controlled to be attracted to the middle position of the second screen body 300, and then the two end positions of the first screen body 200 are controlled to be attracted to the two end positions of the second screen body 300, so as to achieve bubble-free full bonding of each position of the first screen body 200 and the second screen body 300. For the case where the area of the screen body to be bonded is large, by setting multiple magnetic adsorption pairs 3 at different positions, a pressing action can be generated at different positions of the first screen body 200 and the second screen body 300, thereby achieving effective bonding at various positions of the first screen body 200 and the second screen body 300, and by reasonably controlling the attraction order, residual bonding stress can be avoided.
