In its manufacturing process, it needs to go through many key processes such as cleaning, coating, bonding, drying and curing. Among them, the drying and curing process is particularly critical, directly affecting the adhesion, optical performance and overall structural stability of the display materials. Especially in the bonding of liquid crystal panels, the bonding of backlight modules and the shaping of protective film layers, precise temperature control and uniform hot air circulation are necessary to achieve efficient and stable drying and curing effects, so as to ensure the display quality, durability and production consistency of the final product.

[0003] Currently, most existing LCD screen drying equipment relies on manual placement and removal of LCD screens. The operation process is complex and labor-intensive, resulting in low efficiency and difficulty in meeting the needs of modern industry for continuous and automated production. In addition, traditional equipment generally adopts a single-sided air supply structure, which limits the coverage of hot air and leads to uneven heating of LCD screens, affecting drying uniformity and processing efficiency, and ultimately affecting the consistency and stability of product quality.

[0004] Therefore, it is necessary to design an energy-saving LCD screen drying and curing equipment to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0023] Example: An energy-saving liquid crystal display drying and curing device, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a support base 1, a servo motor 2, a transport wheel 3, a transport belt 4, a mounting shell 5, a fan 6, and an air outlet plate 7. The servo motor 2 is bolted to the lower front side of the support base 1. The output shaft of the servo motor 2 is connected to a transport wheel 3. Another transport wheel 3 is rotatably connected to the lower rear side of the support base 1. A transport belt 4 is fitted between the two transport wheels 3. Mounting shells 5 are bolted to the front and rear sides of the top of the support base 1. A fan 6 is installed inside each of the two mounting shells 5. An air outlet plate 7 is provided between the mounting shell 5 and the support base 1, and the air outlet plate 7 is located below the fan 6.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it also includes a heater 8, a heating tube 9, a temperature detector 10, and a control module 11. The heater 8 is installed on the top front side of the support base 1 by bolts. The heating tubes 9 are connected to the left and right sides of the top of the heater 8, respectively. The heating tubes 9 extend into the interior of the mounting shell 5 and are located below the fan 6. The temperature detector 10 is installed on the top rear side of the support base 1 by bolts. The control module 11 is installed on the rear side of the mounting shell 5 by bolts. The control module 11 is electrically connected to the servo motor 2, the fan 6, the heater 8, and the temperature detector 10.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it also includes an air inlet plate 12, a connecting pipe 13, and an air outlet pipe 14. The top left and right sides of the support base 1 are respectively provided with air inlet plates 12. The two air inlet plates 12 are respectively connected to the left and right sides of the air outlet plate 7. The bottom front and rear sides of the two air inlet plates 12 are respectively connected to the connecting pipe 13. The other end of each connecting pipe 13 is inserted into the interior of the support base 1 and located below the conveyor belt 4. Multiple air outlet pipes 14 are evenly connected between the two symmetrical connecting pipes 13.

[0026] like Figure 3 and Figure 5 As shown, it also includes a fixed plate 15, a connecting rod 16, a flap 17, and a torsion spring 18. The fixed plate 15 is installed on the front and rear sides of the support base 1 by bolts. The bottom of the two fixed plates 15 is provided with a connecting rod 16. The flap 17 is rotatably connected to the two connecting rods 16. The torsion spring 18 is connected to the connecting rod 16 between the two flaps 17 and the corresponding fixed plates 15. The flap 17 slides in contact with the conveyor belt 4.

[0027] When using this device, first, place it stably in a dry, well-ventilated working area. Then, connect the power supply, turn on the control module 11, and set parameters such as the target temperature, conveyor belt 4 running speed, and drying time on the control module 11. The control module 11 will automatically detect the working status of the servo motor 2, fan 6, heater 8, and temperature detector 10 to ensure that the system is in normal operating condition. After setting, the control module 11 starts the heater 8, and the heating tube 9 begins to heat the air. At the same time, the fan 6 is started, and the heated air is delivered to the support base 1 through the air outlet 7. The internal drying area is used to dry the top of the LCD screen. Additionally, some hot air enters the air inlet plate 12 through the air outlet plate 7, and then is delivered to multiple air outlet pipes 14 through the connecting pipe 13, evenly spraying the area below the conveyor belt 4 to achieve simultaneous drying of the bottom of the LCD screen, ensuring a more comprehensive and uniform drying effect. The temperature detector 10 collects temperature data in the drying area in real time and feeds it back to the control module 11. The control module 11 dynamically adjusts the heating power and fan speed 6 based on the feedback information to maintain a constant drying environment. Once the temperature in the drying area reaches the set value, preparation can begin. Place the LCD screens to be dried smoothly at the front end of conveyor belt 4. Servo motor 2 drives conveyor wheel 3 to rotate, thereby driving conveyor belt 4 to rotate at a constant speed, causing the LCD screens to move slowly from front to back into the drying area. When the LCD screen approaches the flip plate 17, the flip plate 17 is pushed upward and automatically opens, at which time the torsion spring 18 is compressed. After the screen passes, the flip plate 17 automatically returns to its original position and closes under the action of the torsion spring 18, preventing heat from escaping from the equipment and maintaining a stable temperature in the drying area. The LCD screens move slowly forward on conveyor belt 4, continuously receiving heat from the top and bottom. After hot air drying and curing, the screens that have completed the drying process are output from the rear end of conveyor belt 4. When they pass through flip plate 17 again, flip plate 17 is opened by force. After the screens pass through, flip plate 17 automatically closes, maintaining the sealed state inside the equipment and providing a good environment for subsequent drying operations. After all LCD screens are dried, servo motor 2 and fan 6 are turned off, heater 8 is stopped, and the equipment is allowed to cool down naturally. Then, the dust on the surface of conveyor belt 4 and inside support base 1 is cleaned. If the equipment is not used for a long time, the main power supply should be disconnected and dust protection should be provided. The above operating steps can be repeated for the next use.
