Description

Technical Field

[0001] This utility model relates to the field of displays, specifically to a surface pretreatment device for the production and processing of liquid crystal displays. Background Technology

[0002] In the current monitor manufacturing process, in order to ensure the cleanliness of the monitor during production, surface pretreatment is required in the LCD manufacturing process. Existing pretreatment processes include cleaning, coating, surface modification, curing and post-treatment. In order to deeply remove grease from the monitor and activate the glass surface, plasma cleaning is usually performed on the monitor after the coating process.

[0003] Existing plasma cleaning typically employs an atmospheric pressure plasma cleaning machine consisting of a conveyor belt, a base cabinet located below the conveyor belt, an air supply system and high-frequency power supply located inside the base cabinet, a U-shaped frame clamped above the conveyor belt, and a plasma spray gun assembly suspended on the top surface of the U-shaped frame cavity. The plasma spray gun assembly includes a hydraulic telescopic rod fixed to the top surface of the U-shaped frame cavity by bolts, a connecting plate located on the output shaft of the hydraulic telescopic rod, and several plasma spray guns located on the connecting plate.

[0004] This type of atmospheric pressure plasma cleaner has advantages such as high efficiency, speed, environmental friendliness, and wide applicability. However, existing factories usually use assembly line operations during production. After cleaning, the displays usually flow directly from the end of the conveyor belt of the atmospheric pressure plasma cleaner to the next process conveyor belt. If the displays above the conveyor belt are not limited, they are very easy to be blown off course during the rinsing process, especially some mobile phone or watch displays. This may cause damage to the displays when they flow to the next process due to incorrect positioning. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing surface pretreatment equipment for LCD manufacturing cannot guarantee that the display will not change position during the cleaning process.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a surface pretreatment equipment for liquid crystal display production and processing, comprising an atmospheric pressure plasma cleaning machine consisting of a conveyor belt, a base cabinet located below the conveyor belt, an air supply system and a high-frequency power supply located inside the base cabinet, a U-shaped frame clamped above the conveyor belt, and a plasma spray gun assembly suspended on the top surface of the cavity of the U-shaped frame.

[0007] The plasma spray gun assembly includes a hydraulic telescopic rod fixed to the top surface of the U-shaped frame cavity by bolts, a connecting plate located on the output shaft of the hydraulic telescopic rod, and several plasma spray guns located on the connecting plate.

[0008] The conveyor belt frame is welded with display limiting components located at both ends. The display limiting components are welded to fixed plates above the frame on both sides of the conveyor belt, threaded rods and auxiliary rods passing through the two fixed plates at the beginning and end, sliding blocks sleeved on the threaded rods and auxiliary rods, and limiting strips welded below the sliding blocks. The inner side of the limiting strip is covered with a buffer pad.

[0009] As an improvement, one side of the threaded rod is provided with a hexagonal prism corresponding to the internal hex wrench, and a scale is provided above the auxiliary rod.

[0010] As an improvement, limit strips and buffer pads are also attached to the opposite frame of the conveyor belt's sliding block.

[0011] As an improvement, a controller for controlling the number of plasma spray guns activated and the air pressure of the air supply system is provided on one side of the top surface of the base cabinet.

[0012] As an improvement, the top surface of the U-shaped frame is equipped with an indicator light for detecting the status of the plasma spray gun.

[0013] As an improvement, the top surface of the U-shaped frame cavity and the connecting plate are both connected to the beginning and end of the plasma spray gun by bolts.

[0014] The advantages of this invention compared to the prior art are as follows: This device limits the sliding direction of the display by using a limiting strip and a buffer pad that are tightly attached to the inner wall of the frame on one side of the conveyor belt and below the sliding block, thus preventing the display from shifting during the cleaning process. Furthermore, the sliding block and the threaded rod are connected by a threaded rotation, and the scale on the auxiliary rod ensures the synchronization of the limiting strips on both sides, thereby preventing the display from getting blocked during its movement.

The plasma spray gun assembly 16 includes a hydraulic telescopic rod 161 fixed to the top surface of the cavity of the U-shaped frame 15 by bolts, and a hydraulic telescopic rod 161 located on the output shaft of the hydraulic telescopic rod 161. The base cabinet 12 has a connecting plate 162 and several plasma spray guns 163 located on the connecting plate 162. In order to facilitate the adjustment of the power of the plasma spray guns 163, a controller 3 is provided on one side of the top surface of the base cabinet 12 to control the number of plasma spray guns 163 started and the air pressure of the air supply system 13. The top surface of the U-shaped frame 15 is provided with an indicator light 1631 for detecting the status of the plasma spray guns 163. The top surface of the cavity of the U-shaped frame 15 and the connecting plate 162 are connected to the beginning and end of the plasma spray guns 163 by bolt structure.

[0022] To restrict the movement direction of the display, display limiting components 2 are welded above the frame of the conveyor belt 11 at both ends.

The display is manually inserted from the input end of the conveyor belt 11 and locked between the two limit bars 25. Finally, the plasma spray gun 163 is started, and the conveyor belt 11 is started. After the display completes cleaning, it will automatically flow to the next process conveyor belt.
