Description

Technical Field

[0001] This utility model relates to equipment for manufacturing liquid crystal flat panel displays. More particularly, it relates to a flipping device for the liquid crystal glass plate cell during the manufacturing process of a liquid crystal flat panel display. Background Technology

[0002] A liquid crystal display (LCD) is made by filling a liquid crystal medium between two glass substrates and adding a polarization layer of a certain shape. When a voltage is applied to the liquid crystal medium through a conductive grid, the liquid crystal medium acts as a light switch, thereby forming a certain image.

[0003] Liquid crystal deposition is a crucial stage in the manufacturing process of liquid crystal displays. During this stage, boundary adhesive is applied to the surfaces of two glass substrates. The substrates are then flipped to bring the coated surfaces and the liquid crystal together, followed by pressing and photocuring to form the liquid crystal cell. Due to the large surface area and ultra-thin thickness of the glass substrates, manual flipping is not only inefficient and lacks bonding accuracy, but also prone to breakage, reducing the yield rate.

[0004] Therefore, the applicant filed a patent application for "Glass Substrate Bonding and Flipping Device" on November 12, 2024, with patent number 2024227573383. This patent application uses negative pressure adsorption to perform the gripping, alignment, and bonding operations of glass substrates. However, this technical solution has two shortcomings. First, the stability of negative pressure adsorption is easily affected by ambient temperature and humidity. Low temperature environments reduce airflow, while high humidity environments can affect the sealing effect of negative pressure adsorption. Second, since negative pressure adsorption acts on only one side of the glass substrate, when two glass substrates are just bonded together to form a liquid crystal cell with two glass substrates, this one-sided adsorption effect will affect the bonding and adhesion effect of the two glass substrates, and may even cause the glass plates on the opposite side of the adsorption to delaminate and separate. Therefore, the above-mentioned utility model is not applicable to the manufacturing process of liquid crystal cells. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a display LCD cell flipping clamping device that can be used for flipping LCD cell manufacturing.

[0006] To solve the above-mentioned technical problems, the present invention provides a display LCD cell flipping clamping device, including a clamping bracket. Sliding guide rail seats are symmetrically installed on both sides of the clamping bracket. A sliding clamping frame seat is slidably installed on the sliding guide rail seats via linear sliding guide rails. A sliding clamping frame is fixedly installed on the sliding clamping frame seat. A clamping drive motor is also installed on the sliding guide rail seats, and the clamping drive motor drives the sliding clamping frame via a lead screw and nut pair. An alignment clamping frame is provided at a position opposite to the sliding clamping frame. The alignment clamping frame and the sliding clamping frame form a clamping pair, and the alignment clamping frame is installed on an alignment platform.

[0007] In the above structure, the corresponding alignment clamping frame and sliding clamping frame form a clamping pair, thus enabling the liquid crystal cell to be flipped by clamping. This not only ensures stable and reliable clamping force on the liquid crystal cell, but also prevents it from being affected by environmental factors such as temperature and humidity, ensuring both safe flipping of the substrate and the manufacturing precision of the liquid crystal cell. Furthermore, the sliding clamping frame is mounted on a linear sliding guide rail and a sliding clamping frame base, and the clamping drive motor drives the sliding clamping frame through a lead screw and nut pair, ensuring precise and stable clamping and sliding. The clamping drive motor, through the lead screw and nut pair, can also accurately control the clamping displacement and clamping force.

[0008] In a preferred embodiment of this invention, the alignment clamping frame includes several parallel alignment clamping beams, with alignment clamping strips installed on the clamping sides of each beam. The alignment clamping beams are fixedly mounted to corresponding alignment crossbeams via vertical alignment beams, which are then fixedly mounted to longitudinal alignment beams. The longitudinal alignment beams are mounted on the alignment platform via main alignment beams. This achieves stable and reliable support for the glass substrate or liquid crystal cell.

[0009] In a preferred embodiment of this invention, the sliding clamping frame includes several parallel movable clamping beams, each with a movable clamping strip mounted on its clamping side. The movable clamping beams are fixedly mounted to corresponding movable crossbeams via movable frame vertical beams, and the crossbeams are sequentially mounted to the sliding clamping frame base via movable frame longitudinal beams and movable frame main beams. This achieves stable sliding clamping of the liquid crystal cell.

[0010] In a preferred embodiment of this invention, the clamping bracket adopts a frame structure; the clamping drive motor is a servo motor or a stepper motor; and the alignment platform is a UVW alignment platform. This ensures precise positioning of the glass substrate or liquid crystal cell and protects the substrate. Attached Figure Description
