Description

Technical Field

[0001] This application relates to the field of vehicle-mounted multi-screen bonding technology, and in particular to a multi-screen fixture. Background Technology

[0002] With the development of the automotive industry, consumers have increasingly higher requirements for car interiors, resulting in a growing number of interior screens and larger screen sizes. In the production and assembly process, interior screens are generally assembled by attaching the display screen, which is embedded in a bonding fixture, to a cover plate. However, the size of existing dual-screen and triple-screen products is much larger than that of conventional single-screen equipment. The longer the product size, the greater the deformation during production and assembly, and the lower the precision of adhesion to the cover plate. This leads to a significant increase in the requirements for bonding fixtures during the production of the display screen. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a multi-screen fixture, including a cover plate and a bonding fixture for bonding the multi-screen units. The multi-screen unit includes several display modules. The bonding fixture includes a base with several positioning grooves corresponding to the display modules. An adhesive layer for adhering to the cover plate is provided on the display modules. Several pressing and positioning blocks are also provided on the circumferential surface of the base. The pressing and positioning blocks are used to limit the position of the cover plate, thereby controlling the deformation of the multi-screen unit within a standard value range during assembly and production, and ensuring the positional accuracy of the bonding between the display modules and the cover plate.

[0004] Preferably, the cover plate is covered with an explosion-proof film to protect the display module, thereby preventing hidden damage to the glass during use.

[0005] Preferably, the contact distance between the explosion-proof film and the edge of the cover plate is less than 0.5 mm.

[0006] Preferably, the explosion-proof film is a double-layer film.

[0007] Preferably, the adhesive layer is less than 1 mm away from the display module and the base.

[0008] As can be seen from the above, the following beneficial effects can be obtained by applying the method provided in this application: This application uses a cover plate and a bonding fixture for bonding multiple screens, wherein the multiple screens include several display modules, the bonding fixture includes a base, and the base has several positioning grooves corresponding to the display modules. An adhesive layer for adhering to the cover plate is provided on the display modules. Several pressing and positioning blocks are also provided on the circumferential surface of the base, the pressing and positioning blocks being used to limit the position of the cover plate. By providing the positioning grooves on the base, the display modules can be placed on the base through the positioning grooves, and then... The display module is adhered with an adhesive layer for bonding to the cover plate, allowing the cover plate to be securely attached to the multi-screen unit via the adhesive layer. By providing a bonding fixture for bonding to the multi-screen unit, and by providing several pressing and positioning blocks on the circumference of the base, the multi-screen unit can be integrated and placed using the bonding fixture. This allows the cover plate to be guided and bonded to the display module on the base, improving the accuracy of the bonding position between the display module and the cover plate. This effectively prevents excessive deformation of the multi-screen unit during assembly, ensuring the accuracy of the cover plate's adhesion to the multi-screen unit. Attached Figure Description

[0015] Example

[0016] To address the aforementioned technical problems, this embodiment provides a multi-screen fixture, such as... Figure 1 As shown, the system includes a cover plate 30 and a bonding fixture 20 for bonding the multi-screen 10. The multi-screen 10 includes several display modules 11. The bonding fixture 20 includes a base 21 with several positioning grooves 22 corresponding to the display modules 11. An adhesive layer 23 for adhering to the cover plate 30 is provided on the display modules 11. Several pressing and positioning blocks 24 are also provided on the circumference of the base 21 to limit the position of the cover plate 30. By providing positioning grooves 22 in the base 21, the display modules 11 can be placed on the base 21 through the positioning grooves 22. The adhesive layer for adhering to the cover plate 30 is then attached to the display modules 11. 23, so that the cover plate 30 can be firmly attached to the multi-screen 10 through the adhesive layer 23. By setting the bonding fixture 20 for the multi-screen 10, and by setting a number of pressing and positioning blocks 24 on the periphery of the base 21, the multi-screen 10 can be integrated and placed by the bonding fixture 20. During the process of the cover plate 30 moving down to bond, the pressing and positioning blocks 24 limit the cover plate 30, so that the cover plate 30 can be guided to bond to the display module 11 on the base 21, improving the accuracy of the bonding position between the display module 11 and the cover plate 30, effectively avoiding excessive deformation of the multi-screen 10 during the assembly process, and ensuring the accuracy of the adhesion of the cover plate 30 to the multi-screen 10.

[0017] In the above scheme, such as Figure 2 As shown, the cover plate 30 is covered with an explosion-proof film for protecting the display module 11. By covering the cover plate 30 with an explosion-proof film, the display screen can be effectively prevented from breaking when it is accidentally hit or dropped, and the strength and impact resistance of the glass can be significantly improved, thus avoiding hidden damage caused by the glass during use.

[0018] To ensure product fit tolerances, as a preferred embodiment, the fit distance between the explosion-proof film and the edge of the cover plate 30 is less than 0.5mm, the fit size between the explosion-proof film and the equipment is less than or equal to 1500*400mm, and the fit accuracy between the explosion-proof film and the equipment is: ±0.25mm when the length of the explosion-proof film is 500-1000mm, and ±0.3mm when the length of the explosion-proof film is 1000-1500mm.

[0019] Furthermore, the explosion-proof film is a double-layer film, which further enhances the safety and protective capabilities of the glass, prevents glass shards from flying, and improves the strength and impact resistance of the glass.

[0020] Specifically, the bonding distance between the adhesive layer 23 and the display module 11 and the base 21 is less than 1mm. In this solution, 19 silkscreen marks of the adhesive layer 23 are provided on the base 21.

[0021] In summary, in one or more embodiments of this application, this application provides a multi-screen fixture, including a cover plate and a bonding fixture for bonding the multi-screen. The multi-screen includes several display modules. The bonding fixture includes a base with several positioning grooves corresponding to the display modules. An adhesive layer for adhering to the cover plate is provided on the display modules. Several pressing and positioning blocks are also provided on the circumferential surface of the base to limit the position of the cover plate. By providing positioning grooves in the base, the display modules can be placed on the base through the positioning grooves, and then bonded to the cover plate. An adhesive layer is applied to the cover plate, allowing it to be securely attached to the multi-screen display. A bonding fixture is provided for the multi-screen display, and several pressing and positioning blocks are placed around the base. The multi-screen display can then be integrated and placed using the bonding fixture. During the cover plate's downward bonding process, the pressing and positioning blocks limit the cover plate's position, guiding it to the display modules on the base. This improves the accuracy of the bonding position between the display modules and the cover plate, effectively preventing excessive deformation of the multi-screen display during assembly and ensuring the precision of the cover plate's adhesion to the multi-screen display.

[0022] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
