Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to an edge sealing device for a display screen grating layer. Background Technique

[0002] Most of the existing grating layer edge sealings are carried out with ordinary materials such as glue. Using glue results in poor edge sealing effect of the grating layer, and the inside of the grating layer may be contaminated by the edge sealing material, and the accuracy of this edge sealing material cannot meet the requirements.

[0003] In addition, the operation mode of the existing edge sealing device is cumbersome and time-consuming. A simple and fast fitting method is required to meet the production requirements. Therefore, it is very necessary to accelerate the curing of the edge sealing material, prevent it from penetrating into the inside of the grating layer, and at the same time the edge sealing material can be completely sealed to improve the efficiency of the edge sealing device. Content of the Utility Model

[0004] The purpose of the utility model is to provide an edge sealing device for a display screen grating layer to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An edge sealing device for a display screen grating layer, including

[0007] A fixed base;

[0008] A drip device support is movably installed between the tops of the fixed base, and a drip mechanism is arranged inside the drip device support;

[0009] A driving mechanism is arranged between the fixed base and the drip device support;

[0010] A liquid crystal display screen and a glass cover plate are arranged side by side below the inside of the fixed base.

[0011] Preferably, the driving mechanism includes a transmission guide rod, the transmission guide rod is movably installed inside the tops of both sides of the fixed base, and both ends of the two transmission guide rods are movably connected to the fixed base through bearings;

[0012] Preferably, the driving mechanism further includes a driving motor, the driving motor is fixedly installed outside one end on the right side of the fixed base, the output shaft of the driving motor is fixedly connected to the right transmission guide rod, and movable blocks movably connected to the transmission guide rods are arranged at both ends of the drip device support;

[0013] Preferably, the outside of the left transmission guide rod is smooth, and the outside of the right transmission guide rod is provided with a thread groove;

[0014] Preferably, the dropping mechanism includes a photosensitive resin container which is disposed through one side inside of the dropping device support.

An ultraviolet emitter is fixedly installed below the other side inside of the dropping device support.

[0015] Preferably, a grating layer is pasted on one side of the liquid crystal display screen close to the glass cover plate.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. For the display screen grating layer edge sealing device, through the cooperation among the dropping device support, the ultraviolet emitter, the photosensitive resin dropping head and the photosensitive resin container, the photosensitive resin solution is dropped onto the edge of the grating layer on the liquid crystal display screen through the photosensitive resin dropping head at the bottom end of the photosensitive resin container. The edge of the liquid crystal display screen is tightly sealed with the photosensitive resin, ensuring that the inside of the entire liquid crystal display screen is isolated from the external environment. Meanwhile, the ultraviolet emitter synchronously irradiates the dropped photosensitive resin, enabling the photosensitive resin solution flowing out of the photosensitive resin dropping head to be cured in time at the edge of the liquid crystal display screen housing, preventing the photosensitive resin solution from flowing into the columnar gratings inside the liquid crystal display screen and causing impacts. This device is easy to operate and has a higher edge sealing efficiency.

[0018] 2. For the display screen grating layer edge sealing device, through the cooperation among the driving motor, the bearing, the transmission guide rod, the movable block and the dropping device support, the driving motor controls the rotation of the transmission guide rod at the end. There is a threaded groove on the outer part of the transmission guide rod at this position, so it can drive the movable block close to this position on the dropping device support to move horizontally. The movable block on the other side of the dropping device support is movably sleeved on the transmission guide rod on the left side. Since the surface of the transmission guide rod at this position is smooth, it can guide the dropping device support. In this way, the dropping device support can drive the photosensitive resin dropping head to move horizontally above the liquid crystal display screen, making the grating layer edge sealing more convenient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figure 1-2 shown, a technical solution provided by the present invention:

[0024] A display screen grating layer edge-sealing device includes a fixed base 3; a drip-feeding device support 6 is movably installed between the tops of the fixed base 3. A drip-feeding mechanism is arranged inside the drip-feeding device support 6. The drip-feeding mechanism includes a photosensitive resin container 5. The photosensitive resin container 5 penetrates through one side inside the drip-feeding device support 6. The bottom end of the photosensitive resin container 5 passes through the drip-feeding device support 6 and is communicated with a photosensitive resin drip head 11. An ultraviolet emitter 10 is fixedly installed below the other side inside the drip-feeding device support 6. Below the inside of the fixed base 3, a liquid crystal display screen 9 and a glass cover plate 8 are arranged side by side. A grating layer is pasted on one side of the liquid crystal display screen 9 close to the glass cover plate 8;

[0025] In this embodiment, the photosensitive resin container 5 stores a photosensitive resin solution. The photosensitive resin solution is dripped onto the edge of the grating layer on the liquid crystal display screen 9 through the photosensitive resin drip head 11 at the bottom end of the photosensitive resin container 5. The edge of the outer shell of the liquid crystal display screen 9 is tightly edge-sealed by the photosensitive resin, ensuring that the inside of the entire liquid crystal display screen 9 is isolated from the external environment. At the same time, the ultraviolet emitter 10 synchronously irradiates the dripped photosensitive resin, so that the photosensitive resin solution flowing out of the photosensitive resin drip head 11 is cured in time at the edge of the outer shell of the liquid crystal display screen 9, preventing the photosensitive resin solution from flowing into the columnar gratings inside the liquid crystal display screen 9 and causing an impact. This device is easy to operate and has a higher edge-sealing efficiency.

[0026] As Figure 1 shown, a driving mechanism is arranged between the fixed base 3 and the drip-feeding device support 6. The driving mechanism includes a transmission guide rod 4. The transmission guide rod 4 is movably installed inside the tops of both sides of the fixed base 3. Both ends of the two transmission guide rods 4 are movably connected to the fixed base 3 through bearings 2. The driving mechanism further includes a driving motor 1. The driving motor 1 is fixedly installed outside one end on the right side of the fixed base 3. The output shaft of the driving motor 1 is fixedly connected to the right transmission guide rod 4. Moving blocks 7 that are movably connected to the transmission guide rod 4 are arranged at both ends of the drip-feeding device support 6. The outside of the left transmission guide rod 4 is smooth, and a thread groove is arranged on the outside of the right transmission guide rod 4;

[0027] In this embodiment, when the device is in use, the photosensitive resin drip head 11 can be controlled to move horizontally above the liquid crystal display screen 9. When moving, the driving motor 1 is started, and the driving motor 1 controls the transmission guide rod 4 at the end to rotate. There is a threaded groove on the outside of the transmission guide rod 4 at this position, so it can drive the movable block 7 of the drip device support 6 close to this position to move horizontally. The movable block 7 on the other side of the drip device support 6 is movably sleeved with the transmission guide rod 4 on the left. Since the surface of the transmission guide rod 4 at this position is smooth, it can guide the drip device support 6. In this way, the drip device support 6 can drive the photosensitive resin drip head 11 to move horizontally above the liquid crystal display screen 9, making the edge sealing of the grating layer more convenient.

[0028] Working principle: The photosensitive resin container 5 stores a photosensitive resin solution. The photosensitive resin solution is dripped onto the edge of the grating layer on the liquid crystal display screen 9 through the photosensitive resin drip head 11 at the bottom of the photosensitive resin container 5. The edge of the outer shell of the liquid crystal display screen 9 is tightly sealed with the photosensitive resin to ensure that the inside of the entire liquid crystal display screen 9 is isolated from the external environment. The dripped photosensitive resin is synchronously irradiated by the ultraviolet emitter 10, so that the photosensitive resin solution flowing out of the photosensitive resin drip head 11 is cured in time at the edge of the outer shell of the liquid crystal display screen 9, preventing the photosensitive resin solution from flowing into the columnar grating inside the liquid crystal display screen 9 and causing an impact. When moving, the driving motor 1 is started, and the driving motor 1 controls the transmission guide rod 4 at the end to rotate. There is a threaded groove on the outside of the transmission guide rod 4 at this position, so it can drive the movable block 7 of the drip device support 6 close to this position to move horizontally. The movable block 7 on the other side of the drip device support 6 is movably sleeved with the transmission guide rod 4 on the left. Since the surface of the transmission guide rod 4 at this position is smooth, it can guide the drip device support 6. In this way, the drip device support 6 can drive the photosensitive resin drip head 11 to move horizontally above the liquid crystal display screen 9.
