DETAILED DESCRIPTION
[0019] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0020] Embodiment: A liquid crystal display edge sealing device, please see Figures 1 to 4, including a base 1, a support frame 2, a mounting frame 3, an electric push rod 4, a slider 5, a connecting rod 6, a limiting ring 7, a pressure block 8, a motor 9, a telescopic rod 10, an elastic member 11, a placement frame 12, an ultraviolet lamp 13, a limiting block 14 and a pulley 15. The top middle of the base 1 is horizontally connected to the support frame 2, and a rubber protective cover is arranged at the bottom of the base 1 to prevent the bottom of the base 1 from slipping. The top middle of the support frame 2 is connected to the mounting frame 3, and an electric push rod 4 is vertically installed downward in the middle of the mounting frame 3. The push rod of the electric push rod 4 is connected to the connecting rod 6, and the bottom of the connecting rod 6 is connected to the limiting ring 7, and the bottom of the limiting ring 7 is connected to A pressing block 8 is adapted to the shape of the liquid crystal display screen, a motor 9 is installed in the middle of the slider 5, the output shaft of the motor 9 is connected to the telescopic rod 10, an elastic member 11 is connected between the sleeve of the telescopic rod 10 itself and the slide rod, a placement rack 12 is connected to the tail end of the telescopic rod 10, an ultraviolet lamp 13 is installed on the side of the placement rack 12, and a limiting block 14 is placed on any two sides of the top of the base 1, and a pulley 15 is rotatably connected to the lower outer side of the ultraviolet lamp 13 and the lower outer side of the placement rack 12 to assist the movement of the telescopic rod 10, and a limiting groove adapted to the pulley 15 is arranged on the periphery of the limiting ring 7, and the pulley 15 moves in the limiting groove.
[0021] When it is necessary to perform glue sealing on the edge of the LCD screen, first connect the power supply of the glue sealing device, and install the automatic glue dispensing gun on the placement rack 12, then place the LCD screen under the pressure block 8, and then enable the motor 9 to drive the telescopic rod 10 to rotate. The elastic member 11 on the telescopic rod 10 will change according to the movement trajectory of the telescopic rod 10. Due to the design of the pulley 15 and the limit block 14, the telescopic rod 10 can rotate along the limit ring 7. In this process, the automatic glue dispensing gun is started to perform glue application on the edge of the LCD screen. When the gluing is completed, the automatic glue dispensing machine stops the gluing work. At this time, the staff can align and put the electronic product frame that needs to be glued with the LCD screen, and then start the electric push rod 4, so that the push rod moves downward with the slider 5, the connecting rod 6, the limit ring 7 and the pressure block 8. Under the action of the pressure block 8, the electronic product frame and the LCD screen can be pressed tightly, thereby improving the tightness. At this time, turn on the ultraviolet lamp 13. The irradiation of the ultraviolet lamp 13 can accelerate the curing speed of the glue. When the glue is completely cured, the electric push rod 4 will move upward with the slider 5, the connecting rod 6, the limit ring 7 and the pressing block 8. Finally, the staff can take out the LCD screen after the glue is sealed. Repeat the above operation to seal the edge of the next LCD screen. When the glue sealing device is not needed, the glue sealing device can be powered off.
