Description

Technical Field

[0001] The present application relates to the technical field of liquid crystal screen production, and specifically to a COG liquid crystal screen automated packaging device. Background Art

[0002] "COG" usually refers to "Chip-on-Glass", which is a packaging technology for liquid crystal displays (LCDs). Chip-on-Glass technology integrates the driver chip directly on the glass substrate instead of placing it in a separate package. This integrated design helps to reduce size, reduce weight, and improve the reliability and stability of the display.

[0003] At present, for the LCD industry, the packaging method generally uses foam packaging materials. The existing packaging structure cannot meet the requirements in many dimensions and does not have the effect of flexible adjustment, which brings great difficulties to the subsequent transportation.

[0004] An existing Chinese patent (publication number: CN214987050U) discloses a COG LCD screen packaging structure, including a base, a cavity, a connecting seat, an assembly rod, a first buffer spring, a transmission seat, a cover plate, a fixed seat, a buffer rod, a first roller, a second buffer spring and other structures. An electric telescopic rod is used to control the feed of the base, which is convenient for adjusting the initial spacing between the two limit plates and facilitating the packaging positioning of LCD screens of different specifications. The cover plate is controlled to deflect by rotating the driving screw, which is convenient for controlling the opening and closing of the cover plate, avoiding the cover plate from opening automatically, and facilitating the protection of the LCD screen in the cavity.

[0005] The existing patent can protect the packaged LCD screen, but COG LCD screens usually use some special packaging methods to ensure that the LCD screen is not damaged during transportation and storage. Anti-static bag packaging is a type of COG LCD screen packaging. The COG LCD screen is placed in an anti-static bag to prevent static electricity from affecting it. The existing patent cannot realize automatic bagging of COG LCD screens, and can only protect and guard the COG LCD screen after manual packaging. Utility Model Content

The feeding mechanism 4 of the mouth opening mechanism 5 pushes the COG LCD screen on the conveyor belt 2 3 into the electrostatic packaging bag. It should be noted here that the position detection of the COG LCD screen and the electrostatic packaging bag are both achieved through sensors. The sensor detection technology is also a mature existing technology in the field of automation and will not be repeated in this application. A suction cup 3 6 is fixedly connected to the conveyor belt 1, and a connector 61 connected to the suction cup 3 6 is fixedly connected to the side adjacent to the conveyor belt 1 and the conveyor belt 2 3. The negative pressure tube is connected through the connector 61, so that the suction cup 3 6 can generate negative pressure, thereby sucking the bottom of the electrostatic packaging bag, and the bag mouth opening mechanism 5 can suck the upper part of the electrostatic packaging bag, and then pull the electrostatic packaging bag open to realize the bag mouth opening. The conveyor belt 1 is fixedly connected to the side away from the bag taking mechanism 2 with a material unloading guide plate 8.

The material box 25 has two paddles 26 symmetrically fixed on one side adjacent to the suction cup, and the paddles 26 are elastic metal sheets. The X-axis moving platform 21 drives the support 22 to move, so that the suction cup 24 can move to the top of the material box 25. The material box 25 contains an electrostatic packaging bag prepared in advance. The hydraulic cylinder 23 extends to drive the suction cup 24 to move toward the electrostatic packaging bag in the material box 25. The suction cup 24 works to suck the electrostatic packaging bag, and then the hydraulic cylinder 23 contracts to suck up the electrostatic packaging bag on the top layer. When the electrostatic packaging bag is sucked up, it can pass through the paddle 26. The paddle 26 can peel off and separate another electrostatic packaging bag adsorbed on the bottom of the electrostatic packaging bag being sucked up, so as to avoid sucking up two or more electrostatic packaging bags at one time. After the electrostatic packaging bag is sucked up, the X-axis moving platform 21 moves to move the electrostatic packaging bag to the top of the conveyor belt 1, and the hydraulic cylinder 23 descends to place the electrostatic packaging bag on the conveyor belt 1, and the conveyor belt 1 conveys the electrostatic packaging bag to the bag opening mechanism 5.

When the electrostatic packaging bag equipped with a COG liquid crystal screen reaches below the heat sealing seat 73, the hydraulic cylinder 4 72 extends to drive the heat sealing seat 73 to descend. The heat sealing seat 73 is a pressure head with temperature. When the heat sealing seat 73 contacts the packaging bag, the packaging bag is heated, and the packaging bag is sealed by utilizing the principle of heat shrinkage of the packaging bag. This is also a mature packaging technology and will not be elaborated here. The sealed packaging bag is transported via the conveyor belt 1 and falls into the unloading guide plate 8.
