Description

Technical Field

[0001] The utility model relates to the technical field of LCD production, in particular to a FOG two-way gluing mechanism. Background Art

[0002] The FOG (FPC on Glass) production process is a processing method that achieves mechanical connection and electrical conduction between liquid crystal glass and flexible circuit board by bonding ACF (Anisotropic Conductive Film) and hot pressing under certain temperature, pressure and time. In the FOG process, it is necessary to glue both sides of the LCD glass to cover the ITO on the front of the FOG to protect the circuit from oxidation corrosion, and to cover the intersecting step surface of the FPC and ITO on the back to increase the tension and reliability of the FPC and prevent the FPC gold finger from being broken.

[0003] Then, the existing gluing mechanism can usually only glue one side of the LCD glass. If glue is to be applied to the other side of the LCD glass, the LCD glass needs to be flipped over and moved to another gluing mechanism. This not only increases the complexity and time of the operation, but also easily causes damage or contamination to the LCD glass. In addition, the LCD glass needs to be repositioned after being moved to another gluing mechanism, which results in low gluing accuracy, thereby affecting the quality and performance of the LCD module.

[0024] See also Figure 1 to Figure 2The embodiment of the present application provides a FOG bidirectional glue-spraying mechanism, including a glue-spraying valve 3, a glue-spraying platform 2, and a flipping device 1. The glue-spraying platform 2 is arranged on the flipping device 1, and a vacuum adsorption structure 21 is arranged on the glue-spraying platform 2. The LCD glass 6 to be glued is adsorbed on the glue-spraying platform 2, and the glue-spraying area of ​​the LCD glass 6 is suspended (so that the glue-spraying area will not be blocked by the glue-spraying platform 2 after flipping); the glue-spraying valve 3 is arranged above the glue-spraying platform 2, and the glue-spraying valve 3 is used to glue the glue-spraying area of ​​the LCD glass 6.

[0025] By arranging the glue application platform 2 on the flipping device 1, the LCD is adsorbed on the glue application platform 2 by the vacuum adsorption structure 21. After the glue application valve 3 completes the glue application on the front side of the LCD, the glue application platform 2 can be flipped by the flipping device 1 (in order to avoid the LCD from colliding with the glue application valve 3 during the flipping process, the glue application valve 3 can be removed after the glue application on one side is completed), and then the back side of the LCD can be glued (such as Figure 2 As shown), bidirectional gluing of the LCD is achieved, thereby improving the gluing efficiency of the LCD.

[0026] In one embodiment, the flipping device 1 includes a servo motor 11 and a reducer 12, the power output end of the servo motor 11 is connected to the reducer 12, and the glue-spraying platform 2 is connected to the rotating shaft of the reducer 12. When the LCD needs to be flipped, the servo motor 11 only needs to be controlled to rotate a certain angle to drive the reducer 12 to rotate, thereby flipping the glue-spraying platform 2 and the LCD, so as to facilitate glue-spraying on the other side of the LCD.

[0027] In one embodiment, the adsorption surface of the glue application platform 2 coincides with the rotation axis of the flip device 1. By setting the adsorption surface of the glue application platform 2 to coincide with the rotation axis of the flip device 1, when the LCD is glued on one side and flipped by the flip device 1, the horizontal height of the adsorption surface on the glue application platform 2 does not change substantially, thereby making the horizontal height of the LCD change very little before and after flipping, so that the glue valve 3 can glue the other side of the LCD.

[0028] In one embodiment, a curing device 4 is further included, and the curing device 4 is arranged below the glue-spraying platform 2. The curing device 4 can be a UV lamp. When one side of the LCD is glued, it is turned over by a flipping mechanism so that the glued LCD faces downward. At this time, the curing device 4 is turned on to cure the glue on the LCD (using UV lamp for irradiation). When the other side is glued, it is also turned over and cured by the curing device 4. By setting the curing device 4, the LCD can be cured while being glued on both sides, without the need to transport the glued LCD to other curing mechanisms for curing, thereby improving the production efficiency of the LCD module.

[0029] In one embodiment, a glue gun cleaning device 5 is further included. The glue gun cleaning device 5 is arranged on one side of the glue valve 3. The glue gun cleaning device 5 includes a cleaning cloth roll. The two ends of the cleaning cloth roll are respectively wound on a turntable (two turntables pull up the cleaning cloth roll). When the glue valve 3 completes a glue application action, the glue valve 3 will move to the top of the glue gun cleaning device 5, and the gun head of the glue valve 3 will be inserted into the cleaning cloth roll. The glue valve 3 is cleaned with the cleaning cloth roll to remove the residual glue on the glue gun to ensure the quality of glue application. After each glue cleaning, the two turntables will rotate a certain distance to turn away the cleaning cloth roll with residual glue, and rotate the clean cleaning cloth roll to the cleaning position, so that the glue gun cleaning device 5 can continue to clean the glue valve 3.

[0030] In one embodiment, the vacuum adsorption structure 21 includes a plurality of adsorption holes arranged on the adsorption surface of the glue application platform 2 and a vacuum hose 211 connected to the adsorption holes, and the vacuum hose 211 is connected to a vacuum pump. The vacuum adsorption force generated by the vacuum pump is transmitted to the adsorption holes through the pipeline, so that the LCD located on the surface of the adsorption hole is adsorbed by the vacuum adsorption force, preventing the LCD from loosening during the glue application process, and the use of the vacuum adsorption structure 21 to fix the LCD can greatly reduce the probability of the LCD being damaged due to clamping and fixing.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
