Description

Technical Field

[0001] The utility model relates to the technical field of film sticking devices, in particular to an integrated sticking device suitable for sticking products with small rounded corners. Background Art

[0002] In the current electronic product manufacturing field, display screen film laminating technology plays a vital role. Among them, roller film laminating, as an efficient and precise film material laminating method, has been widely used in the production process of various display screens. Roller film laminating technology has been widely recognized by the market for its excellent laminating quality, high precision and high production efficiency. However, with the continuous emergence of new display screen products such as four-curved and full-curved screens, the market demand for small rounded corner product laminating technology is also increasing.

[0003] Small rounded corner products refer to those with small corner transition radius. The film application process of such products, especially the application of the R-angle edge area, has extremely high requirements for the design and technology of the film application roller. Due to technical limitations, the diameter of the roller of the traditional roller film application device is difficult to be small enough. Therefore, when applying small rounded corner products, it is often difficult to roll to the R-angle edge, resulting in the inability to fully apply the small rounded corner area of ​​the product or a false application. This not only affects the appearance quality of the product, but may also have a potential impact on the performance and life of the product.

[0004] In order to solve this problem, a film pasting device suitable for pasting small rounded corners and right-angled products with announcement number CN210822959U uses a roller with multi-point support to perform the film pasting operation. This device improves the ability to adhere to small rounded corner products by reducing the roller diameter. However, although the multi-point support method solves the problem of excessive roller diameter to a certain extent, there is still a risk of inadequate rolling or false pasting because some areas of the roller do not obtain stable support. This risk is particularly prominent when pasting films on four-curved or full-curved products with higher pasting requirements. Utility Model Content

[0050] In the manufacturing of electronic products, display screen film technology is very important. With the rise of new display screens such as quad-curved and full-curved screens, the film technology of small rounded corner products has become the focus. Figure 1 , Figure 1 This is the front view of a product with small rounded corners. Due to the limitation of roller diameter, the traditional roller laminating technology is difficult to achieve accurate laminating on products with small rounded corners. Especially in the R-corner edge area, incomplete laminating or false laminating often occurs, which affects product quality and performance. Therefore, a roller laminating device with multi-point support is proposed. Please refer to Figure 2, reducing the roller diameter and improving the adhesion ability of products with small rounded corners. However, there is still a problem of lack of support in some areas of the roller, which can easily lead to the risk of inadequate rolling or false adhesion, especially when applying film to high-demand products such as four-curved or full-curved screens. Therefore, it is necessary to further optimize the roller design and technology to meet the market's higher requirements for film application technology for products with small rounded corners.

[0051] To solve the above problems, please refer to Figures 3 to 8 The embodiment of the utility model provides an integrated attachment device suitable for attaching products with small rounded corners, comprising:

[0052] The roller bracket 20, as a main supporting structure, provides a stable installation base for the installation of various components.

[0053] The flanges 30 are installed on both sides of the roller bracket 20 to ensure the structural stability of the device. A miniature bearing 31 is installed on each flange 30 . The roller bracket 20 is provided with a mounting groove 21 , which is located between the two flanges 30 .

[0054] The roller auxiliary shaft 40 is arranged on both sides of the axial symmetry of the installation groove 21, and is used in conjunction with the flange 30 to facilitate the installation and positioning of the roller auxiliary shaft 40. A plurality of roller support bearings 41 are rotatably mounted on each roller auxiliary shaft 40. The roller auxiliary shaft 40 is used to support the roller support bearings 41. The roller bracket 20 is provided with avoidance grooves 22 corresponding to the plurality of roller support bearings 41, which facilitate the free rotation of the roller support bearings 41, realize spatial avoidance, and avoid structural interference and the inability to achieve normal operation.

[0055] The middle connecting member 50 , as a connecting and fixing structure, is used to fix the roller auxiliary shaft 40 on the roller bracket 20 , and to make the roller support bearings 41 on the two roller auxiliary shafts 40 be staggered and distributed at equal intervals.

[0056] The film-applying roller 60 is the core component of the device, and is used to perform the film-applying operation. The outer peripheral side of the film-applying roller 60 is in contact with the roller support bearing 41 to ensure the rotation stability of the film-applying roller 60 during the film-applying process. The two ends of the film-applying roller 60 are respectively installed in the micro-bearings 31 to support the flexible and stable rotation of the film-applying roller 60. It should be noted here that the provision of multiple intermediate connecting members 50 realizes the integration of the device structure, ensuring that each part of the film-applying roller 60 can be stably and effectively supported, so that the small fillet area of ​​the small fillet product can be well rolled and attached, avoiding the risk of inadequate rolling or false attachment caused by multi-point support.

[0057] The rolling cylinder 70 is disposed above the roller bracket 20 and serves as a power driving device for driving the roller bracket 20 to rise or fall, thereby achieving the film material attachment action on the surface of the product with small rounded corners, ensuring the accuracy and uniformity of the attachment.

[0058] In this example, see Figure 6 and Figure 7 , the intermediate connecting member 50 comprises:

[0059] The mounting portion 52 is arranged on the mounting groove 21, and is designed to achieve stable connection and support. A mounting through hole is provided at the bottom of the mounting groove 21, and a fixing screw hole 521 corresponding to the mounting through hole is provided on the mounting portion 52. This design ensures that the mounting portion 52 is tightly and firmly fixedly connected to the roller bracket 20 through the screw connection, thereby improving the stability of the overall device.

[0060] The limiting portion 53 is designed to ensure the accurate installation position and stability of the roller auxiliary shaft 40. The limiting portion 53 is protruded on both sides of the end of the mounting portion 52 away from the fixing screw hole 521 and is staggered. The limiting portion 53 is used to limit and fix the roller auxiliary shaft 40 on the roller bracket 20, effectively ensuring the stability of the roller auxiliary shaft 40 during operation, avoiding deviation or shaking, and separating the multiple roller support bearings 41 installed on the roller auxiliary shaft 40 at equal intervals, so that each roller support bearing 41 can be fully supported, effectively ensuring the stability and reliability of the film-sticking roller 60 during operation.

[0061] A limiting inclined surface 54 is provided at one end of the limiting portion 53 close to the auxiliary roller shaft 40. The limiting inclined surface 54 is used to limit and fix the position of the auxiliary roller shaft 40 on the roller bracket 20. This design enables the auxiliary roller shaft 40 to be accurately matched during installation, effectively avoiding shaking or deviation caused by inaccurate installation position, thereby ensuring the rotation stability and reliability of the roller support bearing 41 installed on the auxiliary roller shaft 40. The installation portion 52 is also provided with an avoidance groove 522 corresponding to the roller support bearing 41. The opening of the avoidance groove 522 fully considers the movement trajectory and required space of the roller support bearing 41 during the rotation process, provides sufficient activity space for the roller support bearing 41, and prevents interference and friction between the roller support bearing 41 and the installation portion 52. This not only improves the flexibility and smoothness of the rotation of the roller support bearing 41, but also helps the film-applying roller 60 to achieve a more uniform and stable attachment effect.

[0062] The mounting groove 21 has stepped grooves 211 on both sides of the axial symmetry, and the auxiliary roller shaft 40 is arranged on the stepped grooves 211. This design not only provides a stable support point for the auxiliary roller shaft 40, but also further ensures that the auxiliary roller shaft 40 can be accurately and quickly positioned during installation. Through the guidance of the stepped grooves 211, the auxiliary roller shaft 40 can maintain a stable installation state and effectively avoid shaking or deviation during operation. At the same time, in order to ensure that the roller support bearing 41 can rotate smoothly, the avoidance groove 22 is connected to the stepped groove 211, providing sufficient activity space for the roller support bearing 41 to avoid interference or friction with the roller bracket 20, which helps to extend the service life of the device while ensuring the attachment effect of the film roller 60.

[0063] For further information, see Figure 3 and Figure 4 The integrated attachment device suitable for attaching products with small rounded corners also includes:

[0064] The fixing frame 10 and the rolling cylinder 70 are installed on the fixing frame 10 to ensure the firmness of the installation of the rolling cylinder 70, thereby providing a stable power transmission foundation.

[0065] The mounting block 80 is connected to the transmission end of the rolling cylinder 70 through the connecting block 71 to ensure efficient and accurate power transmission.

[0066] The adjusting bracket 90 is adjustably mounted on a side of the mounting block 80 away from the rolling cylinder 70. The mounting block 80 serves as a supporting platform for the adjusting bracket 90, thereby enhancing the stability of the overall structure. The roller bracket 20 is adjustably mounted on the adjusting bracket 90. The adjusting bracket 90 is used to adjust the attachment position of the film roller 60 relative to the small rounded corner product, which not only improves the adaptability and flexibility of the device, but also ensures accurate and stable attachment effects on small rounded corner products of various specifications and sizes.

[0067] Specifically, see Figure 4The mounting block 80 has a fine-tuning device 81 and an auxiliary elastic member 85 at both ends of the axial direction, which complement each other and work together to fine-tune the attachment process. The adjustment end of the fine-tuning device 81 passes through the mounting block 80 and abuts against the adjustment bracket 90, allowing the user to make subtle adjustments to the horizontality of the film-applying roller 60 without having to move the entire device over a large range to ensure the accuracy of attachment. One end of the auxiliary elastic member 85 is connected to the mounting block 80, and the other end is connected to the adjustment bracket 90, which assists the fine-tuning device 81 to achieve high-precision adjustment. A connection protrusion 91 is convexly provided in the middle of one side of the adjustment bracket 90 close to the rolling cylinder 70, and a first installation groove adapted to the connection protrusion 91 is provided on the mounting block 80. 82, the connecting protrusion 91 is rotatably installed in the first installation groove 82 through the installation piece 84, so that the user can adjust the posture of the film roller 60 according to actual needs, ensure the stability of the structural connection, and further improve the adaptability and flexibility of attachment. The fine-tuning device 81 is used to cooperate with the auxiliary elastic member 85 to adjust the horizontality of the film roller 60. This design not only improves the flatness of the contact surface between the film roller 60 and the small rounded corner product, but also helps to achieve a more uniform and stable attachment effect, thereby ensuring the accuracy and reliability of the attachment of the small rounded corner product.

[0068] An adjustment auxiliary block 94 is also protruding from the adjustment bracket 90, and the adjustment auxiliary block 94 is arranged on the side of the connecting protrusion 91. A second mounting groove 83 corresponding to the adjustment auxiliary block 94 is also opened on the mounting block 80. An arc-shaped convex surface is provided at one end of the adjustment auxiliary block 94 close to the second mounting groove 83. Here, the design of the adjustment auxiliary block 94 plays the role of a lever fulcrum in the process of adjusting the horizontality of the film-laminating roller 60 to meet the structural stability of the horizontality adjustment process.

[0069] For further information, see Figure 3 , Figure 5 and Figure 6 In order to flexibly adjust the attachment position between the film-applying roller 60 and the small rounded corner product, the adjustment bracket 90 is also provided with an installation adjustment slot 92, and the roller bracket 20 can be adjusted and installed on the installation adjustment slot 92, so as to flexibly adjust the relative position between the film-applying roller 60 and the small rounded corner product according to different product characteristics and attachment requirements. This design can ensure accurate and stable attachment effects on small rounded corner products of various specifications and sizes, and further improve the quality and efficiency of film material attachment.

[0070] There are also protruding connecting blocks 23 on both sides of the roller bracket 20. The adjustment bracket 90 is provided with an adjusting protrusion 93 that can reciprocate along the length direction of the installation adjustment groove 92. The connecting block 23 is connected to the adjusting protrusion 93 through an adjusting connecting piece. The setting of the adjusting protrusion 93 provides a flexible adjustment range for the roller bracket 20. The adjusting connecting piece is used to cooperate with the adjusting protrusion 93 to lock the position of the roller bracket 20 on the adjusting bracket 90, ensure the stability of the structural connection, and ensure that the roller bracket 20 maintains a stable posture during the film material attachment process to obtain a reliable film material attachment effect.

[0071] Also, see Figure 7 and Figure 8 The intermediate connecting member 50 is in a "Y" shape. This "Y"-shaped design not only makes the intermediate connecting member 50 more stable and compact in structure and able to withstand greater pressure and load, but also makes it more convenient during installation and adjustment, further enhancing the stability and reliability of the entire attaching device. An avoidance arc groove 51 corresponding to the film-sticking roller 60 is also provided on the intermediate connecting member 50 to avoid interference during assembly and use, thereby ensuring the installation accuracy of the film-sticking roller 60.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
