Description

[0002] The display screen includes a display panel, and the display panel is connected to a printed circuit board via a chip-on-chip film. In the prior art, when producing a display screen, it is often necessary to apply insulating resin glue at the edge of the display panel where the terminal is connected to the chip-on-chip film, so as to provide insulation and corrosion protection and enhance the connection strength.

[0049] See also Figures 1 to 3 , Figure 1The structural schematic diagram of the dispensing device in one embodiment of the present application is shown. A dispensing device 1000 provided in one embodiment of the present application includes: a carrier 1100, a plurality of dispensing mechanisms 1200 and a dispensing carrier 1300, the carrier 1100 is provided with a carrier surface 1110 on one side along a first direction, a plurality of dispensing mechanisms 1200 are arranged at intervals along a second direction, the dispensing mechanism 1200 includes a dispensing valve 1210 and a first driving component 1220 located on the carrier surface 1110, a dispensing valve 1210 is provided on the side away from the carrier surface 1110 (not shown in the figure), and the first driving component 1220 includes a first driving member 1 221, the fixed end of the first driving member 1221 is slidably connected to the bearing surface 1110 along the second direction, the output end of the first driving member 1221 is connected to the dispensing valve 1210, the first driving member 1221 is configured to drive the dispensing valve 1210 to rotate around an axis parallel to the second direction, the dispensing platform 1300 is located on one side of the dispensing mechanism 1200 along the third direction, the dispensing platform 1300 is slidably connected to the bearing surface 1110, and can approach or move away from the dispensing mechanism 1200 along the third direction, and the first direction, the second direction and the third direction are arranged to intersect each other.

[0050] In this embodiment, the staff places the display screen (not shown) on the dispensing platform 1300, so that the back of the display screen contacts the dispensing platform 1300 and the front of the display screen is away from the dispensing platform 1300, and then drives the dispensing platform 1300 to slide on the bearing surface 1110 along the third direction, so that the display screen is close to the dispensing mechanism 1200 along the third direction, until the display screen moves to the side of the dispensing valve 1210 away from the bearing surface 1110 along the first direction, the dispensing platform 1300 stops moving, and then the dispensing operation is performed. The specific dispensing process is as follows: the first driving member 1221 moves along the first direction, and the dispensing valve 1210 moves along the second direction. The first driving member 1221 drives the dispensing valve 1210 to move synchronously while sliding on the bearing surface 1110 in one direction. When the dispensing valve 1210 moves to the side of the area to be dispensed (not shown in the figure) on the back of the display screen along the first direction, the first driving member 1221 stops sliding and drives the dispensing valve 1210 to rotate around an axis parallel to the second direction to change the dispensing direction of the dispensing port of the dispensing valve 1210, so that the dispensing port of the dispensing valve 1210 is inclined in a direction to the back of the display screen, and dispenses glue to the terminal (not shown in the figure) on the area to be dispensed on the display screen. Since the dispensing direction of the dispensing port is not perpendicular to the back of the display screen, the glue spitted out by the dispensing port is difficult to hang on the outer surface of the terminal, and the dispensing position on the terminal can dispense enough glue. In summary, the glue dispensing device 1000 in this embodiment drives the glue dispensing valve 1210 to rotate around an axis parallel to the second direction through the first driving member 1221, so that sufficient glue can be dispensed on the back of the display screen, thereby improving the glue dispensing effect.

In addition, the glue dispensing device 1000 has a simple structure and is inexpensive to manufacture, which is conducive to reducing costs.
