Description

Technical Field

[0001] This utility model relates to the field of display screen manufacturing technology, and more specifically to a dust removal device for the production and processing of liquid crystal displays. Background Technology

[0002] Liquid crystal displays (LCDs) are a type of flat panel display used for television and computer screens. Their advantages include low power consumption, small size, and low radiation. LCDs are also used in digital clocks and many portable computers.

[0003] A search revealed an existing patent (publication number: CN218460408U) that discloses a dust removal device for LCD screen manufacturing. In its operation, a motor drives a turntable to rotate via a shaft at the output end. The turntable, through toothed blocks on its surface, further drives a rotating rod, which in turn rotates a bottom-mounted blade. The airflow generated by the rotating blade blows internal dust towards the lower part of the processing chamber. Then, by activating an air pump, the air pump's suction pipe at the output end further acts on the suction block, effectively absorbing the dust inside the device and preventing it from rising and being exposed to the air. This solves the problem of existing devices that directly absorb dust during processing by activating a suction pump and suction pipe. However, the inventors discovered the following problem with the existing technology during the development of this invention: In the aforementioned dust removal device, the display screen is simply placed horizontally on the surface of a horizontal plate during processing. Under this condition, the processing angle of the display screen is easily limited, making the processing difficult to carry out smoothly.

[0004] In view of this, the present invention proposes a dust removal device for the production and processing of liquid crystal displays. Utility Model Content

[0008] Furthermore, the blower assembly includes a blower embedded in the top of the dust collection box. The blower's air inlet is equipped with a dust filter, and the blower's air outlet is fixedly installed with an annular pipe. Several air outlet pipes are evenly arranged on the surface of the annular pipe, and the air outlet ends of the air outlet pipes face the surface of the positioning plate. After the display screen is processed, the sealing door is closed. Through the blower, the annular pipe, and the air outlet pipes, air can be blown onto the surface of the display screen to prevent dust from adhering to the display screen surface, thereby achieving the purpose of dust removal from the display screen surface.

[0009] Furthermore, the dust collection assembly includes a dust collection hood embedded at the bottom of the dust collection box. The top of the dust collection hood is connected to the bottom of the dust collection box. An exhaust fan is embedded in the lower side of the dust collection hood. The air inlet of the exhaust fan extends into the interior of the dust collection hood and is fixedly installed with an intercepting net. By setting up the dust collection hood and the exhaust fan, the exhaust fan draws air from the interior of the dust collection hood. Then, under the interception and filtration effect of the intercepting net, the dust can be collected inside the dust collection hood by using negative pressure, preventing dust from overflowing the dust collection box and ensuring a clean processing environment.

[0010] Furthermore, a dust discharge port is provided on the bottom side of the dust collection hood, and an insert plate is inserted on the front of the dust collection hood corresponding to the dust discharge port; after the processing is completed, the dust inside the dust collection hood can be discharged from the dust collection hood by pulling out the insert plate.

[0011] Furthermore, the clamping and positioning component includes a threaded push rod threadedly connected to the inner wall of the stepped positioning groove, and the threaded end of the threaded push rod is rotatably connected to a clamping plate for positioning the display screen; when positioning the display screen, by rotating the threaded push rod, the clamping plate can be used to clamp and position the display screen, and it is suitable for positioning LCD displays of different sizes.

[0012] Furthermore, the telescopic end of the hydraulic rod extends into the interior of the first mounting box and is fixedly mounted with a rack, and a gear plate is fixedly mounted inside the first mounting box on the vertical shaft, with the rack meshing with the gear plate.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model places the LCD screen on the stepped positioning groove surface of the positioning plate and clamps it in place. The screen is processed from the front of the dust collection box. During the processing of the screen, by setting an adjustment component, the vertical shaft is driven to rotate by a hydraulic rod, which can drive the positioning plate to rotate horizontally and adjust the processing position of the screen horizontally. The horizontal shaft is driven to rotate by a servo motor, which can flip the positioning plate and adjust the processing elevation angle of the screen, reducing the limitations of the processing angle during the processing process, thereby providing convenience for processing and production.

[0017] 2. This utility model, by setting up a dust collection hood and an exhaust fan, uses the exhaust fan to draw air from inside the dust collection hood. Then, under the interception and filtration effect of the interception net, the dust can be collected inside the dust collection hood using negative pressure, preventing dust from overflowing the dust collection box and ensuring a clean processing environment. After the display screen is processed, the sealing door is closed. While the exhaust fan draws air from inside the dust collection hood, the blower, annular pipe, and exhaust pipe can blow air onto the surface of the display screen, preventing dust from adhering to the display screen surface and achieving the purpose of further dust removal from the display screen surface. After the processing is completely finished, the dust inside the dust collection hood can be discharged from the dust collection hood by pulling out the insert plate.

The air inlet of the exhaust fan 16 extends into the interior of the dust collection hood 15 and is fixedly installed with an interception net 17.

[0031] By setting up a dust collection hood 15 and an exhaust fan 16, the exhaust fan 16 draws air from inside the dust collection hood 15. Then, under the interception and filtration effect of the interception net 17, the dust can be collected inside the dust collection hood 15 by using negative pressure, preventing dust from overflowing from the dust collection box 1 and ensuring a clean processing environment.

[0032] The blower assembly includes a blower 12 embedded at the top of the dust collection box 1.
