Description

Technical Field

[0001] The utility model relates to the technical field of grating lamination, in particular to a display screen grating film lamination device. Background Art

[0002] Display screen grating film lamination is a key process step in the manufacture of liquid crystal displays. It involves the process of pasting the grating film onto the liquid crystal panel. The grating film is a component used to enhance the quality of liquid crystal displays, especially playing an important role in enhancing display contrast and viewing angle.

[0003] When the display screen and the grating film are bonded together, a high degree of overlap is required between the two. Therefore, a bonding device is usually used to assist the operation. However, the existing grating film bonding device is not convenient for fine-tuning the position of the display screen so that it can be positioned and overlapped with the grating film during the auxiliary operation. Therefore, it is necessary to design a display screen grating film bonding device. Utility Model Content

[0024] A display screen grating film laminating device comprises a frame 8; a suction mechanism is arranged at the top of the frame 8, the suction mechanism comprises vacuum suction cups 10, the vacuum suction cups 10 are arranged at the four corners of the middle part of the frame 8, a vacuum pump 11 is fixedly installed at one side of the middle bottom end of the frame 8, the vacuum pump 11 is connected to the four vacuum suction cups 10 through a pipeline, and a columnar grating film 5 and a liquid crystal display screen 6 are arranged in sequence at the upper end of the suction mechanism;

[0025] In the present embodiment, during operation, the columnar grating film 5 is first placed on the middle upper end surface of the frame 8, and then the vacuum pump 11 is started. After the vacuum pump 11 is started, the four vacuum suction cups 10 are controlled to absorb the columnar grating film 5 with negative pressure, and then the liquid crystal display screen 6 is placed on the upper end surface of the columnar grating film 5 for bonding, so that it remains stable during the bonding process to avoid movement, thereby reducing the difficulty of bonding.

[0026] like Figure 1 and Figure 2 As shown, the top sides of the frame 8 are respectively provided with fine adjustment mechanisms, the fine adjustment mechanisms include guide grooves 14, the guide grooves 14 are opened on the top sides of the frame 8, the two guide grooves 14 are perpendicular to each other, the fine adjustment mechanism also includes a support 2, the support 2 is arranged on the inner side of the edge of the two guide grooves 14 close to the frame 8, a lead screw 3 is movably installed in the middle of the support 2, an anti-slip handle 1 is fixedly installed on the outer side of the end of the lead screw 3, and movable blocks 13 are movably installed on the outside of both ends of the lead screw 3, and the tops of the two movable blocks 13 are respectively provided with a wedge-shaped triangle plate 1 4 and a wedge-shaped triangle plate 2 12, and the threads at the two ends of the lead screw 3 are opposite;

When fine-tuning, the anti-slip handle 1 is twisted, and the anti-slip handle 1 controls the rotation of the lead screw 3. Since the threads at both ends of the lead screw 3 are opposite, the two movable blocks 13 will move in opposite directions and drive the wedge-shaped triangle plates 1 4 and wedge-shaped triangle plates 2 12 to move synchronously. Since the wedge-shaped triangle plate 2 12 is movably arranged on the outer side of the edge of the liquid crystal display screen 6, when the wedge-shaped triangle plate 2 12 moves horizontally, it can push the liquid crystal display screen 6 to move horizontally, and then the positions of the columnar grating film 5 and the liquid crystal display screen 6 can be adjusted, thereby achieving the purpose of facilitating fine-tuning.

[0030] Working principle: During operation, first place the columnar grating film 5 on the middle upper end surface of the frame 8, then start the vacuum pump 11. After the vacuum pump 11 is started, the four vacuum suction cups 10 are controlled to absorb the columnar grating film 5 with negative pressure, and then the liquid crystal display screen 6 is placed on the upper end surface of the columnar grating film 5 for bonding. After the liquid crystal display screen 6 is placed on the upper end surface of the columnar grating film 5, the horizontal angle of the liquid crystal display screen 6 can be fine-tuned by controlling the two pairs of wedge-shaped triangle plates 1 4 and wedge-shaped triangle plates 2 12 to move in opposite directions. When fine-tuning, twist the anti-slip handle 1, and the anti-slip handle 1 controls the rotation of the lead screw 3. Since the two ends of the lead screw 3 are The threads are opposite, so the two movable blocks 13 will move in opposite directions and drive the wedge-shaped set plate 1 4 and the wedge-shaped set plate 2 12 to move synchronously. Since the wedge-shaped set plate 2 12 is movably arranged outside the edge of the liquid crystal display screen 6, when the wedge-shaped set plate 2 12 moves horizontally, it can push the liquid crystal display screen 6 to move horizontally. After the positions of the columnar grating film 5 and the liquid crystal display screen 6 are adjusted, the CCD camera 7 is started. The CCD camera 7 is used to collect digital content at the intermediate viewpoint. By comparing it with the preset digital content, it can quickly determine whether the liquid crystal display screen 6 and the columnar grating film 5 are correctly attached.
