Technical Field
[0001] This utility model relates to the field of light-shielding tape splicing technology, and in particular to a light-shielding tape auxiliary splicing component. Background Technology
[0002] Light-shielding tape is a widely used material in backlight modules of electronic products (such as LCD modules and LED modules), and is also widely used in vehicles. Its main functions are adhesion and light shielding, aiming to prevent light leakage within the backlight module and avoid interference from external light on the display screen. With the popularization and development of electronic products, especially small and medium-sized LCD screens, the demand for light-shielding tape is increasing, and the requirements for its performance are also becoming more stringent.
[0003] In the production process of light-blocking tape, when it is necessary to switch between new and old materials, tape splicing is required. In the traditional splicing method, the edges of the tape are prone to curling, so it is necessary to prevent curling while splicing, which is quite troublesome. Therefore, it is necessary to consider how to solve this problem. Utility Model Content

[0022] Reference Figure 1-Figure 3 A light-shielding tape-assisted docking assembly includes a base plate 1;
[0023] It also includes a positioning mechanism, which includes a rectangular strip 5 fixedly connected to the upper end of the base plate 1. A cavity 12 is provided inside the rectangular strip 5. Multiple communication ports 6 are opened at the top of the cavity 12. A negative pressure pump 3 is installed on the front side of the base plate 1. The air inlet end of the negative pressure pump 3 is connected to a connecting pipe 4. The other end of the connecting pipe 4 is connected to the inside of the cavity 12.
[0024] The system also includes a pressing mechanism to improve the stability of the connection. The pressing mechanism includes a vertical plate 2 fixedly connected to the upper end of the base plate 1, a horizontal plate 7 fixedly connected to the front side of the vertical plate 2, a guide strip 8 running through the horizontal plate 7, the guide strip 8 being a rectangular strip, the guide strip 8 being slidably connected to the horizontal plate 7, a pressure plate 11 fixedly connected to the lower end of the guide strip 8, the pressure plate 11 cooperating with the rectangular strip 5, a pressing block 9 fixedly connected to the upper end of the guide strip 8, and the lower end of the pressing block 9 being elastically connected to the upper end of the horizontal plate 7 by a spring 10.
[0025] In this invention, when connecting light-shielding tapes, a connecting tape is first cut to a fixed length to form connecting tape a. The back side (i.e., the non-adhesive side) of connecting tape a is attached to the upper end of rectangular strip 5. By activating the negative pressure pump 3, negative pressure is generated inside cavity 12. Using multiple connecting ports 6, connecting tape a is suctioned by negative pressure. Then, one end of the old light-shielding tape is attached to the upper left part of the connecting tape a, and one end of the new light-shielding tape is attached to the upper right part of the connecting tape a. Next, the connecting tape is cut to a fixed length to form connecting tape b. The adhesive layer of connecting tape b is placed downwards and attached to the upper side of the two light-shielding tapes. Finally, the pressing block 9 is pressed down, and the pressure plate 11 is moved down through the guide strip 8 to pressurize the whole formed by connecting tape b, connecting tape a, and the two light-shielding tapes, ensuring a tight connection. The entire process can be completed by a single person, effectively avoiding the situation where the edges of the light-shielding tape curl and affect the operation.
