Abstract
Description
Technical Field
[0001] This utility model relates to the field of display device technology, specifically to bonding fixtures and water-based adhesive bonding equipment. Background Technology
[0002] In modern electronic device manufacturing, the bonding between the screen (such as an LCD screen or OLED screen) and the cover plate (such as a touch screen or glass) is one of the key processes.
[0003] To ensure the optical performance and durability of the screen, a water-based adhesive bonding process is typically used. This involves applying a hydrogel material between the screen body and the cover plate to achieve a strong bond. In actual production, water-based adhesive needs to be applied to the surfaces of both the screen body and the cover plate. The cover plate is then flipped over and attached to the screen body. After the water-based adhesive cures, the screen body and the cover plate are permanently connected.
[0004] To improve product quality, it is essential to ensure the bonding precision between the cover plate and the screen body. Therefore, in traditional water-based adhesive bonding processes, fixtures are typically used for positioning the screen body and cover plate. However, production involves various sizes and types of products, each requiring the creation of corresponding bonding fixtures. When the product range is extensive, the number of fixtures increases significantly, leading to higher costs and a heavier management burden. Furthermore, frequent fixture changes reduce the overall efficiency of the production line, making it difficult to meet the needs of large-scale production. Utility Model Content

Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] The following is combined Figures 1 to 12 The following describes embodiments of the present invention.
[0035] According to an embodiment of the present invention, in a first aspect, a fitting fixture 10 is provided, including a base 11, a screen limiting structure 12, and a cover plate limiting structure 13. The screen limiting structure 12 includes at least two screen limiting slide rails 121 and at least two screen limiting blocks 122. The screen limiting slide rails 121 are disposed on the base 11, and each screen limiting block 122 is adjustablely disposed on the screen limiting slide rail 121. The screen limiting structure 12 is adapted to abut against the side of the screen 200 to limit the screen 200 in both its length and width directions. The cover plate limiting structure 13 includes at least two cover plate limiting slide rails 131 and at least two cover plate limiting blocks 132. The cover plate limiting slide rails 131 are disposed on the base 11, and each cover plate limiting block 132 is adjustablely disposed on the cover plate limiting slide rail 131. The cover plate limiting structure 13 is adapted to abut against the side of the cover plate 300 to limit the cover plate 300 in both its length and width directions. The screen limiting slide rails 121 and the cover plate limiting slide rails 131 do not overlap.
[0036] The screen limiting structure 12 includes at least two screen limiting slide rails 121 and at least two screen limiting blocks 122. These limiting blocks can be freely adjusted on the slide rails, allowing the bonding fixture 10 to flexibly adjust the limiting position of the screen 200 in the length and width directions according to actual needs, thereby adapting to screens 200 of various sizes (such as LCD screens or OLED screens). Regardless of the size of the screen 200, precise positioning can be achieved simply by adjusting the position of the limiting blocks, ensuring the stability and consistency of the bonding process.
[0037] Cover plate limiting structure 13: Similar to the screen limiting structure 12, the cover plate limiting structure 13 also employs a design of at least two cover plate limiting slide rails 131 and at least two cover plate limiting blocks 132. These limiting blocks can also move along the slide rails to accommodate cover plates 300 of different sizes (such as touch screens or glass). Furthermore, the screen limiting slide rails 121 and the cover plate limiting slide rails 131 do not overlap, ensuring sufficient operating space between them, avoiding interference, and enabling compatibility with multi-size product bonding, thus improving the versatility and reliability of the bonding fixture 10.
[0038] Therefore, the fitting fixture 10 provided by this utility model achieves high efficiency compatibility with products of various sizes, which not only simplifies the production process, but also improves the flexibility and response speed of the production line.
[0039] In traditional processes, each size of product requires a custom-made fitting fixture 10, resulting in high costs. However, the fitting fixture 10 of this invention, due to its high versatility and adjustability, can be applied to products of various sizes, significantly reducing the demand for dedicated fixtures. It eliminates the need to redesign and manufacture fixtures for each new product model, thereby saving a significant amount of material and manufacturing costs.
[0040] In summary, the fitting fixture 10 of this utility model, through optimized design, not only achieves efficient compatibility with products of multiple sizes, but also saves a significant amount of fixture costs, bringing significant cost advantages and economic benefits to enterprises.
[0041] In some embodiments, at least two screen limiting slide rails 121 are collinear.
[0042] When at least two screen limiting slide rails 121 are collinearly arranged, the collinear arrangement of the slide rails ensures precise alignment of the screen 200 in the length direction. This arrangement allows both sides of the screen 200 to be consistently limited along the same straight line. When the two screen limiting blocks 122 abut against the diagonals of the screen 200, both the length and width of the screen 200 are limited, improving positioning accuracy during the bonding process.
[0043] Meanwhile, when only two screen limit slide rails 121 and two screen limit blocks 122 are set, the operator only needs to adjust the position of the two screen limit blocks 122 to complete the limit of the screen 200, which simplifies the operation steps, reduces human error, and improves work efficiency.
[0044] In some embodiments, four screen limiting slide rails 121 are provided, with the four screen limiting slide rails 121 arranged in pairs opposite each other and collinearly, and four screen limiting blocks 122 are provided, respectively located on the four screen limiting slide rails 121.
[0045] When four screen limiting slide rails 121 are set, and arranged in pairs opposite each other and collinearly, the four screen limiting blocks 122 can fully limit the screen 200 in both length and width directions. The two slide rails in each direction apply limiting action from both sides, ensuring precise fixation of the screen 200 in all dimensions and effectively preventing any displacement of the screen 200 during the bonding process. Specifically, the four screen limiting blocks 122 can abut against the four corners of the screen 200, or against at least two opposite sides of the screen 200.
[0046] The four-rail design allows for flexible adaptation to screens 200 of different proportions and sizes. By adjusting the positions of the four limit blocks, precise positioning can be achieved in different directions, enabling the fitting fixture 10 to be compatible with a wider variety of products.
[0047] Each screen limiting block 122 is mounted on a screen limiting slide rail 121, and its position can be adjusted independently according to actual needs. This ensures that the screen limiting block 122 on each screen limiting slide rail 121 can accurately fit the edge of the screen 200, providing the most suitable limiting effect. This not only improves the fitting accuracy but also enhances the flexibility and adaptability of the fitting fixture 10.
[0048] In some embodiments, when the screen body 200 is clamped, the top of the screen body limiting block 122 is not higher than the top surface of the screen body 200.
[0049] Since the cover plate 300 is larger than the screen body 200, setting the top of the screen body limiting block 122 to be no higher than the top surface of the screen body 200 can effectively prevent physical interference between the screen body limiting block 122 and the cover plate 300 or other components during the bonding process. Especially when bonding the screen body 200 and the cover plate 300, it ensures sufficient space between them for precise alignment and bonding, and prevents the bonding accuracy from being affected by the protrusion of the screen body limiting block 122.
[0050] At the same time, this design reduces pressure and friction on the surface of the screen 200, lowering the risk of scratches or damage caused by contact between the screen limiting block 122 and the screen 200. This is especially important for high-precision, high-quality display screens, ensuring the screen 200 remains intact during the bonding process.
[0051] In some embodiments, multiple cover plate limiting slide rails 131 are provided and distributed in four areas surrounded by two adjacent screen limiting slide rails 121, and multiple cover plate limiting slide rails 131 are provided at intervals within the areas.
[0052] The cover plate limiting slide rails 131 are distributed among the four areas enclosed by two adjacent screen limiting slide rails 121, making full use of the space of the base 11 and avoiding mutual interference between the screen limiting slide rails 121 and the cover plate limiting slide rails 131. This not only improves the space utilization of the entire fixture, but also allows each slide rail to work independently without interfering with each other.
[0053] Meanwhile, the multi-zone, multi-rail design allows the fixture to adapt to cover plates 300 of different sizes and shapes. By flexibly adjusting the number and position of the rails in each zone, optimal limiting effects can be achieved in different application scenarios, enhancing the fixture's versatility and adaptability.
[0054] In addition, multiple cover plate limiting slide rails 131 are spaced apart in each area to ensure that the cover plate 300 is adequately limited in both length and width directions. The multiple slide rails apply limiting action from different angles, keeping the cover plate 300 in the ideal position throughout the fitting process and avoiding any possible displacement or skewness.
[0055] Furthermore, the multiple cover plate limiting slide rails 131 are distributed in a dispersed manner, making the supporting force on the cover plate 300 more uniform during the bonding process. This not only improves the stability of the bonding process, but also reduces stress concentration caused by uneven local force, further improving the bonding quality.
[0056] The number of cover plate limiting slide rails 131 can be redundantly designed, and the number of cover plate limiting blocks 132 depends on the specifications of the cover plate 300 to be positioned. Usually, the screen body 200 has a conductive lead-out protruding on one side. To avoid interference, the cover plate limiting blocks 132 and screen body limiting blocks 122 can be set on the other three sides instead of this side.
[0057] In some embodiments, the cover plate limiting block 132 is provided with a guide groove 1321, an elastic element 1322 and a positioning pin 1323. The positioning pin 1323 is adapted to the guide groove 1321 and is telescopically disposed in the guide groove 1321 through the elastic element 1322.
[0058] The guide groove 1321 provides a clear movement path for the positioning pin 1323, enabling the positioning pin 1323 to be accurately embedded in the preset position, thereby ensuring that the cover plate 300 is accurately positioned relative to the screen body 200.
[0059] In the dispensing process, water-based adhesive is applied to one surface of the cover plate 300, and then the cover plate 300 is flipped over to bond the adhesive-coated surface of the cover plate 300 to the adhesive-coated surface of the screen body 200. During the flipping process, the flipping mechanism 40 rotates the cover plate 300 and accurately positions it on the screen body 200, achieving bonding between the cover plate 300 and the screen body 200. During this process, the flipping mechanism 40 compresses the positioning pin 1323, which locks within the guide groove 1321 to achieve a clearance effect. After the cover plate 300 and the screen body 200 are bonded, the flipping mechanism 40 separates from the cover plate 300 and removes the cover plate 300. The positioning pin 1323 is reset under the action of the elastic element 1322. The positioning pin 1323 extends out and abuts against the side of the cover plate 300 to limit its position, ensuring that the cover plate 300 and the screen body 200 maintain precise positioning during the curing process of the water-based adhesive. Thus, after the water-based adhesive is cured, the cover plate 300 and the screen body 200 are precisely positioned and firmly bonded.
[0060] Specifically, in some embodiments, the elastic element 1322 is a spring.
[0061] In some embodiments, the guide groove 1321 is configured as a step structure 1324 that avoids the cover. The step structure 1324 includes a transverse end face parallel to the base 11 and a vertical end face perpendicular to the base 11. The outer peripheral surface of the positioning pin 1323 protrudes at least partially from the vertical end face of the step structure 1324.
[0062] By setting the guide groove 1321 as a stepped structure 1324, after the cover plate 300 is placed, the lateral end face of the step is spaced apart from the lower surface of the cover plate 300, and the vertical end face of the step is spaced apart from the side of the cover plate 300. This prevents the cover plate limiting block 132 from putting pressure and friction on the surface of the cover plate 300, and reduces the risk of scratches or damage caused by the contact between the cover plate limiting block 132 and the cover plate 300.
[0063] In some embodiments, when the cover plate 300 is clamped, the top of the locating pin 1323, which is subjected only to the elastic force of the elastic element, is higher than the top surface of the cover plate 300.
[0064] With this configuration, the positioning pin 1323 can abut against the cover plate 300 across its entire thickness along the thickness direction, increasing the contact area between the positioning pin 1323 and the cover plate 300. This makes the positioning pin 1323's positioning of the cover plate 300 more stable and secure, improving the positioning accuracy of the cover plate 300. Consequently, it enhances the bonding accuracy between the cover plate 300 and the screen body 200, ensuring product quality.
[0065] In some embodiments, the screen limiting slide rail 121 and the cover plate limiting slide rail 131 are each provided with a plurality of first mounting holes 141 at intervals, and the screen limiting block 122 and the cover plate limiting block 132 are each provided with second mounting holes 142 that are adapted to the first mounting holes 141. The screen limiting block 122 and the screen limiting slide rail 121, as well as the cover plate limiting block 132 and the cover plate limiting slide rail 131, are all detachably connected by fasteners 143.
[0066] By providing multiple first mounting holes 141 within the screen body limiting slide rail 121 and the cover plate limiting slide rail 131, and providing corresponding second mounting holes 142 on the screen body limiting block 122 and the cover plate limiting block 132, precise alignment between the various components is ensured. The position and spacing of each mounting hole can be designed according to the dimensions of the screen body 200 and the cover plate 300, enabling accurate positioning of each component during installation and avoiding positional deviations.
[0067] The use of fasteners 143 (such as bolts, screws, etc.) for detachable connection provides a reliable fixing method. Fasteners 143 can ensure a tight connection between the screen body limiting block 122 and the screen body limiting slide rail 121, and between the cover plate limiting block 132 and the cover plate limiting slide rail 131, enhancing the stability of the entire structure and preventing loosening or displacement during use.
[0068] Meanwhile, fasteners 143 enable detachable connections, allowing the screen limiting block 122 and cover plate limiting block 132 to be easily removed from the slide rail for replacement or maintenance. Multiple first mounting holes 141 allow operators to select different mounting positions for the screen limiting block 122 or cover plate limiting block 132 according to actual needs, enabling flexible adjustments. This allows the fixture to adapt to screens 200 and covers 300 of different sizes or shapes, improving the equipment's versatility and flexibility.
[0069] With the preset first mounting hole 141, second mounting hole 142 and fastener 143, the assembler only needs to align the screen body limiting block 122 with the first mounting hole 141 on the screen body limiting slide rail 121 or the cover plate limiting block 132 with the first mounting hole 141 on the cover plate limiting slide rail 131 and fix it with the fastener 143. There is no need for complicated alignment and calibration operations, which simplifies the assembly process and improves work efficiency.
[0070] In some embodiments, the second mounting hole 142 is a strip hole.
[0071] By setting the second mounting hole 142 as a strip-shaped hole, a small range of positional adjustments are allowed when assembling the screen limiting block 122 with the first mounting hole 141 of the screen limiting slide rail 121, and when assembling the cover plate limiting block 132 with the first mounting hole 141 of the cover plate limiting slide rail 131. This ensures precise matching of the screen limiting block 122 with the screen 200 and the cover plate limiting block 132 with the cover plate 300, guaranteeing that the screen limiting block 122 and the cover plate limiting block 132, while providing limiting, will not cause pressure or friction on the product, preventing wear and improving product quality. Simultaneously, because the strip-shaped hole has a certain length, the fastener 143 can be adjusted within a certain range, allowing the fixture to adapt to screens 200 and cover plates 300 of different sizes or tolerances, increasing the versatility and applicability of the equipment and reducing customization requirements.
[0072] According to an embodiment of the present invention, in a second aspect, a water-based adhesive bonding device 100 is also provided, including a bonding station 20, a flipping station 30, and a bonding fixture 10 as described above. The flipping station 30 is located on one side of the bonding station 20; the bonding fixture 10 is located at the bonding station 20.
[0073] Specifically, a flipping mechanism 40 is provided on the flipping station 30. The flipping mechanism 40 clamps the cover plate 300. After water-based adhesive is applied to one surface of the cover plate 300, the flipping mechanism 40 drives the cover plate 300 to flip, so that the adhesive surface of the cover plate 300 is bonded to the adhesive surface of the screen body 200 located in the bonding fixture 10. After the flipping mechanism 40 drives the cover plate 300 to flip, it moves from the flipping station 30 to the bonding station 20. During the movement, the flipping mechanism 40 compresses the positioning pin 1323. After the flipping mechanism 40 is removed from the bonding station 20, the positioning pin 1323 is reset under the action of the elastic element 1322, thereby limiting the position of the cover plate 300.
[0074] Furthermore, in some embodiments, the water-based adhesive bonding equipment 100 also includes a dispensing mechanism 50, which is movably disposed on the worktable and can move between the bonding station 20 and the flipping station 30.
[0075] Since the water-based adhesive bonding equipment 100 includes the bonding fixture 10 and has all the technical effects of the bonding fixture 10, it will not be described in detail here.
[0076] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
