Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted screen production equipment, in particular to a UV delayed bonding double-sided adhesive tape. Background Art

[0002] With the development of automobile electronics and intelligence, the in-vehicle screen, as an important interface for human-computer interaction, has occupied an increasingly important position in automobile design. In the production and assembly of in-vehicle screens, a very important step is the assembly of the outer screen glass panel. Panel assembly usually requires high precision and high stability to ensure the display effect and service life of the screen. The traditional bonding solution is acrylic closed-cell foam tape with high adhesion, high cohesion and excellent weather resistance. In addition to the above advantages, acrylic closed-cell foam tape also has unique viscoelastic properties, which can compensate for the deformation stress caused by the different thermal expansion and contraction ratios of the panel and frame when they are heated for a long time, and reduce the risk of the two sides of the panel being detached due to deformation stress. Therefore, it has become a common choice for panel bonding. However, there are also certain problems with the use of acrylic foam tape. Due to the requirement for high adhesive force, this type of tape generates adhesive force immediately after contact, which limits the fine-tuning operation during the assembly process, easily causing deviations in the assembly position and affecting the final assembly quality. In response to this, a UV delayed bonding double-sided tape is proposed, so that the adhesive force of the adhesive surface of the tape will gradually increase after being activated by ultraviolet light (UV). This feature allows the operator to repeatedly position the tape in the early stages of the bonding operation to ensure the precise assembly of the vehicle screen panel, and after the positioning is completed, the glass panel can be continuously and stably fixed, greatly improving the flexibility and accuracy of the assembly.
