Description
Technical Field
[0001] This utility model relates to the technical field of display screen assembly, and in particular to a bonding device for large-size curved screens. Background Technology
[0002] With the development of automotive intelligence and technology, in-vehicle displays are playing an increasingly important role in car interiors. To provide users with a more immersive visual experience and enhance the technological feel of vehicles, in-vehicle curved screens are trending towards larger areas and more complex curved designs. Large-area curved screens, with their unique visual effects and space-saving advantages, are gradually becoming standard equipment in high-end cars.
[0003] However, the assembly of large-area curved screens faces numerous technical challenges. Among these, the bonding between the glass panel and the back cover is particularly prominent. Due to the increased size and curved shape of the glass panel in large-area curved screens, accurately bonding it to the back cover is significantly more difficult. In traditional bonding processes, it is often difficult to guarantee precise alignment between the glass panel and the back cover during bonding. On the one hand, the curved shape of a large-area curved screen makes it difficult to distribute the force evenly across different parts during bonding, easily leading to misalignment of the glass panel. On the other hand, the larger size of curved screens makes them more susceptible to human error and equipment inaccuracies during operation, further increasing the risk of bonding misalignment. Bonding misalignment can lead to light leakage. When the glass panel and back cover are not accurately bonded, light will leak out from the gap between them, affecting not only the display effect, reducing contrast and clarity, but also the user's visual experience, and potentially being perceived as a product quality defect. Furthermore, light leakage can also increase the display's energy consumption and reduce its lifespan.
[0004] Therefore, in order to solve the above problems, the large-size curved screen bonding device of this application is proposed. Utility Model Content

[0009] A bonding assembly includes a driving component, a material-picking plate, and several suction components. The material-picking plate is disposed on the driving component, and the suction components are spaced apart on the material-picking plate. When the driving component moves the material-picking plate closer to the adhesive groove, the suction components bond the glass panel to the double-sided adhesive in the adhesive groove. When the driving component moves the material-picking plate away from the adhesive groove, the suction components remove the glass panel from the adhesive groove. When the driving component moves the material-picking plate closer to the rear shell groove, the suction components bond the side of the glass panel closest to the double-sided adhesive to the rear shell.

[0017] Optionally, a plurality of through holes are respectively opened on both ends of the first release film, and each of the positioning posts is respectively inserted into each of the through holes so that the colloid is fitably accommodated in the adhesive groove.
[0018] Optionally, the suction element is an electric suction cup.
[0019] Compared with the prior art, the present invention has at least the following advantages:
[0020] This utility model relates to a large-size curved screen bonding device, comprising a support base and a bonding assembly. The support base has spaced-apart adhesive grooves and a back shell groove. Several positioning posts are arranged on the support base near the adhesive grooves. The adhesive grooves are used to accommodate glass panels, and the positioning posts are used to position the double-sided adhesive so that the double-sided adhesive is properly accommodated in the adhesive grooves. The back shell groove is used to accommodate the back shell. The bonding assembly includes a driving component, a material picking plate, and several suction components.

[0032] like Figure 1 and Figure 2As shown, a large-size curved screen bonding device 10 includes a support base 100 and a bonding assembly 200. The support base 100 has spaced adhesive grooves 121 and a back shell groove 122. Several positioning posts 300 are arranged on the support base 100 near the adhesive grooves 121. The adhesive grooves 121 are used to accommodate a glass panel 410, and the positioning posts 300 are used to position double-sided adhesive 420 so that the double-sided adhesive 420 is appropriately accommodated within the adhesive grooves 121. The back shell groove 122 is used to accommodate a back shell 430. The bonding assembly 200 includes a driving component, a material-taking plate 210, and several suction components 220. The material-taking plate 210 is disposed on the driving member, and each adsorption member 220 is disposed at intervals on the material-taking plate 210. The driving member is used to drive the material-taking plate 210 closer to the adhesive groove 121 so that the adsorption members 220 adhere the glass panel 410 to the double-sided adhesive 420 in the adhesive groove 121. The driving member is used to drive the material-taking plate 210 away from the adhesive groove 121 so that the adsorption members 220 pick up the glass panel 410 from the adhesive groove 121. The driving member is used to drive the material-taking plate 210 closer to the rear shell groove 122 so that the adsorption members 220 adhere the side of the glass panel 410 near the double-sided adhesive 420 to the rear shell 430.
[0033] It should be noted that the adhesive application groove 121 and the rear shell groove 122 are located on the same side of the support base 100, and there is a gap between the adhesive application groove 121 and the rear shell groove 122. Furthermore, to achieve automated production, the drive unit can be configured as a multi-axis robot. Specifically, the material picking plate 210 is fixedly mounted on the output shaft of the drive unit, and each suction element 220 is spaced apart on the material picking plate 210. In one embodiment, the suction element 220 is an electric suction cup. Thus, the drive unit moves the material picking plate 210 closer to or further away from the adhesive application groove 121 / rear shell groove 122. The following describes the working principle of the large-size curved screen bonding device 10 of this application. First, the glass panel 410 is placed in the adhesive tray 121. Then, the driving component drives the picking plate 210 to pick up the glass panel 410 from the adhesive tray 121 through the suction components 220. Then, the double-sided adhesive 420 is positioned by the positioning post 300 so that the double-sided adhesive 420 is accurately placed into the adhesive tray 121. Then, the release film on the upper surface of the double-sided adhesive 420 is manually peeled off. Then, the driving component drives the picking plate 210 to move, so that the suction components 220 adsorb the glass panel 410 and descend to the surface of the double-sided adhesive 420, so that the double-sided adhesive 420 is bonded to the lower surface of the glass panel 410. Then, the driving component raises the material-picking plate 210 again, manually peels off the release film on the lower surface of the double-sided adhesive 420, and then the driving component moves the material-picking plate 210 to move the glass panel 410, which is fixed by the adsorption component 220, to the top of the rear shell groove 122. Finally, the driving component lowers the material-picking plate 210, so that the side of the glass panel 410 covered with double-sided adhesive 420 is attached to the rear shell placed in the rear shell groove 122. During this process, the driving component applies a certain pressure to the glass panel 410 to maintain pressure between the glass panel 410 and the rear shell 430 for a certain period of time, thus assisting in the bonding and installation of the large-size curved screen. In this way, by driving the material-picking plate 210 with precision, the double-sided adhesive 420 is precisely bonded to the glass panel 410, and the glass panel 410 is precisely bonded to the rear shell 430, effectively improving the bonding accuracy of the large-size curved screen.
[0034] like Figure 1 and Figure 2 As shown, in one embodiment, the support base 100 includes a coordinate platform 110 and a carrier 120. The carrier 120 is detachably mounted on the coordinate platform 110, and the adhesive groove 121, the rear shell groove 122, and the positioning post 300 are all located on the carrier 120.
[0035] It should be noted that the coordinate stage 110 and the carrier 120 are detachably installed using screws. The carrier 120 is used to support the glass panel 410, double-sided adhesive 420, and back cover 430. Thus, when it is necessary to install curved screens of different sizes, only the carrier 120 needs to be replaced, which can effectively improve the compatibility of the device.
[0036] like Figure 2As shown, in one embodiment, a plurality of guide posts 130 are provided on the coordinate stage 110, and a plurality of guide holes 123 are provided on the carrier 120. When the carrier 120 is placed on the coordinate stage 110, each guide post 130 passes through each guide hole 123.
[0037] It should be noted that when the carrier 120 is replaced, in order to enable the carrier 120 to be quickly positioned with the coordinate table 110, a guide post 130 is set on the coordinate table 110, and a guide hole 123 is correspondingly opened on the carrier 120 so that the guide post 130 fits through the guide hole 123, thereby accurately positioning and installing.
[0038] like Figure 2 As shown, in one embodiment, two backlight slots 111 are formed on the coordinate stage 110. The backlight slots 111 are used to accommodate the light-emitting module. The two backlight slots 111 are aligned with the adhesive application slot 121 and the back shell slot 122, respectively. Light-transmitting holes 124 are formed on the inner bottom walls of both the adhesive application slot 121 and the back shell slot 122. The light-transmitting holes 124 are connected to the backlight slots 111.
[0039] It should be noted that, in order to improve the bonding accuracy between the glass panel 410, double-sided adhesive 420, and back cover 430, a backlight groove 111 is formed on the coordinate stage 110, and light-transmitting holes 124 are formed on the inner bottom walls of the adhesive groove 121 and the back cover groove 122. A light-emitting module, such as an LED light block, is installed in the backlight groove 111, emitting light that shines through the light-transmitting hole 124. A light detector is installed on the pick-up plate 210. When the pick-up plate 210 moves the suction component 220 to the correct position above the adhesive groove 121 / back cover groove 122, the light detector can detect the light emitted from the light-transmitting hole 124. This effectively improves the positional accuracy of the bonding of the glass panel 410, double-sided adhesive 420, and back cover 430.
[0040] like Figure 3 As shown, in one embodiment, a directional post 440 is provided on the back side of the glass panel 410. When the glass panel 410 is accommodated in the adhesive groove 121, the directional post 440 passes through the light-transmitting hole 124.
[0041] It should be noted that, in this way, when the directional post 440 is inserted into the light-transmitting hole 124 in the adhesive application groove 121, it means that the glass panel 410 is precisely placed in the adhesive application groove 121.
[0042] like Figure 2 As shown, in one embodiment, some of the positioning posts 300 are located at one end of the adhesive groove 121, and the remaining positioning posts 300 are located at the other end of the adhesive groove 121, and the spacing between the positioning posts 300 at both ends of the adhesive groove 121 is different.
[0043] It should be noted that when the orientation of the double-sided tape 420 placed in the adhesive tray 121 needs to be fixed, the design in this embodiment can achieve a foolproof function. Specifically, several positioning posts 300 are respectively provided at both ends of the adhesive tray 121 along its length. For example, two positioning posts 300 are provided at any end of the adhesive tray 121. The distance between the two positioning posts 300 at the two ends of the adhesive tray 121 is not the same. In this way, only when the double-sided tape 420 is placed in the adhesive tray 121 in the correct orientation can the double-sided tape 420 avoid the positioning posts 300 and be accurately placed in the adhesive tray 121.
[0044] like Figure 4 As shown, in one embodiment, the double-sided adhesive 420 includes a first release film 421, an adhesive 422, and a second release film 423, which are sequentially stacked to form the double-sided adhesive 420.
[0045] It should be noted that the double-sided tape 420 is placed in the adhesive tray 121, with the first release film 421 abutting against the inner bottom wall of the adhesive tray 121. After manually tearing off the second release film 423, the glass panel 410 is placed into the adhesive tray 121 by the suction member 220, so that the adhesive 422 adheres to the glass panel 410. Then, after the suction member 220 lifts the glass panel 410, the first release film 421 is manually torn off again, so that the adhesive 422 is exposed on the bottom side of the glass panel 410.
[0046] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, a plurality of through holes 4211 are respectively opened on both ends of the first release film 421. When each positioning post 300 is respectively inserted into each through hole 4211, the colloid 422 is adapted to be contained in the adhesive groove 121.
[0047] It should be noted that when the positioning posts 300 pass through each corresponding through hole 4211, it indicates that the double-sided adhesive 420 can be accurately placed in the adhesive groove 121. In this way, the bonding efficiency and accuracy between the adhesive 422 and the glass panel 410 can be improved through the auxiliary positioning structure.
[0048] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
