Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display screen production technology, and in particular to a drying device for LCD liquid crystal display screen production. Background Technology

[0002] Liquid crystal display (LCD) manufacturing technology refers to the process of combining liquid crystal materials with electronic components and optical parts through multiple steps, including array substrate preparation, liquid crystal infusion, polarizer lamination, and module assembly, to create LCD devices capable of displaying images. Drying the LCD screen removes residual moisture from substrate cleaning and solvents from the lamination adhesive, preventing issues such as affecting the accuracy of subsequent processes or causing bubbles or display abnormalities in the finished product.

[0003] Under current conditions, a drying device for LCD screen production, as disclosed in CN222378709U, is commonly used. This device includes a drying assembly and a blower. The drying assembly comprises a body, a first conveying pipe, a three-way pipe, a second conveying pipe, and a housing. It includes an adjustment structure; when a servo motor is activated, it drives a threaded rod to rotate inside a first movable groove. However, this device only transports the screen via a conveyor belt and a support plate. The screen lacks fixation on the conveyor belt, making it prone to displacement and collision due to conveying vibrations or airflow. This can lead to scratches or misalignment of the screen surface, affecting the quality of the dried product. Furthermore, the contact angle between the screen and the heat source is fixed, resulting in sufficient heating on the side closest to the heat source, while the sides, edges, or back are insufficiently heated. This can easily lead to localized over-drying or under-drying, resulting in residual moisture or surface damage due to high temperatures. Utility Model Content

[0004] The purpose of this invention is to solve the problem of uneven drying caused by a single conveyor belt conveying the display screen in the prior art, and to propose a drying equipment for LCD screen production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drying device for LCD screen production includes a drying box with support legs, a material discharge hole on the drying box, a fixed rod fixedly installed inside the drying box, a rotating frame rotatably installed inside the drying box, and three circumferentially distributed fixed frames 1 and 2 fixedly installed on the rotating frame. A drying rack for driving the screen to rotate and dry is mounted on the fixed frame 1 via a transmission component, and a limiting frame for limiting the screen is mounted on the drying rack via a pin. A limiting block is fixedly installed on the limiting frame, and a clamping structure for clamping the limiting block is provided on the drying rack. Circumferentially distributed electric heating dryers for drying the screen are provided inside the drying box.

[0007] Preferably, the drying box is provided with a sealing door corresponding to the discharge hole, the rotating frame is sleeved on the fixed rod, and the drying frame has two placement slots for placing the display screen.

[0008] Preferably, the transmission component includes a fixed gear fixedly mounted on a fixed rod, a transmission rod rotatably mounted on a first fixed frame and connected to the fixed rod, and a transmission gear meshing with the fixed gear fixedly mounted on the transmission rod, a rotating rod rotatably mounted on the first fixed frame and integrally connected to the upper end of the drying rack and connected to the transmission rod, and a conveyor belt connecting the rotating rod rotatably to the transmission rod via a pulley, and a rotating rod rotatably mounted on the second fixed frame and integrally connected to the lower end of the drying rack.

[0009] Preferably, the rotating rod is vertically positioned and extends above the fixed frame, and the fixed gear is horizontally positioned above the rotating frame.

[0010] Preferably, the clamp structure includes a clamp frame fixedly installed on the drying rack, and a lifting rod for limiting the position of the limiting block is slidably sleeved inside the clamp frame. A moving block is fixedly installed on the lifting rod, and a spring that cooperates with the lifting rod is welded between the moving block and the clamp frame.

[0011] Preferably, the limiting block has a limiting hole corresponding to the lifting rod, and a lever is fixedly installed at the upper end of the lifting rod.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model achieves rapid positioning of the display screen to be dried through a clamp structure. The traction block moves, and the traction block drives the moving block to press the spring through the lifting rod. The lifting rod is disconnected from the limiting block, the traction limiting frame opens, and the display screen to be dried is placed into the corresponding placement slot. The limiting frame is closed and the traction block is released. The spring drives the lifting rod through the moving block to limit the limiting block. No tools are needed, which helps to shorten the loading and unloading time. Through the three circumferentially distributed fixed frames and drying racks, multiple display screens can be dried at the same time, ensuring that the products all get a consistent drying effect, which helps to improve work efficiency.

[0014] 2. This utility model achieves the rotational drying of the display screen through a transmission component. The drive motor drives the rotating frame to rotate, and the rotating frame drives the transmission rod and transmission gear to rotate synchronously through the fixed frame. The transmission gear meshes with the fixed gear, and the conveyor belt drives the rotating rod to rotate. At the same time, the fixed frame drives the display screen to rotate, and the drying frame drives the display screen to rotate, so that the display screen is heated evenly, which helps to improve the drying uniformity and the consistency of product quality.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A drying device for LCD screen production includes a drying box 1 with support legs, a controller on the drying box 1, a material discharge hole on the drying box 1, a fixing rod 2 fixedly installed inside the drying box 1, the fixing rod 2 being vertically positioned at the center of the drying box 1, a rotating frame 4 rotatably installed inside the drying box 1, and a drive motor on the drying box 1 that drives the rotating frame 4 to rotate and is electrically connected to the controller.

[0023] Three circumferentially distributed fixed frames 5 and 6 are fixedly installed on the rotating frame 4. The three fixed frames 5 and 6 are evenly distributed at a 120° angle and simultaneously support multiple displays for drying operations.

[0024] A drying rack 9 for driving the display screen to rotate and dry is installed on the fixed frame 5 via a transmission component. The transmission component, through the cooperation of the fixed gear 3, transmission rod 10, transmission gear 11, rotating rod 7, conveyor belt and rotating rod 8, enables the drying rack 9 to rotate on its own axis while revolving with the rotating frame 4, so that the display screen is heated evenly and the drying quality and efficiency are improved.

[0025] The drying rack 9 is equipped with a limiting frame 12 for limiting the display screen. A limiting block 13 is fixedly installed on the limiting frame 12. The drying rack 9 is provided with a clamping structure for clamping the limiting block 13. The clamping structure, through the cooperation of the clamping frame 14, the lifting rod 15, the moving block 16 and the spring 17, realizes the quick clamping and loosening of the limiting block 13. The limiting and fixing of the display screen can be completed without tools, shortening the loading and unloading time and improving the work efficiency.

[0026] The drying chamber 1 is equipped with circumferentially distributed electric heating dryers 18 for drying the display screen. The electric heating dryers 18 are electrically connected to the controller. The circumferentially distributed electric heating dryers 18 ensure that the temperature inside the drying chamber 1 is uniform, providing a stable drying environment for the display screen.

[0027] The drying chamber 1 is equipped with a sealing door corresponding to the discharge hole. The sealing door maintains the airtightness of the drying chamber 1 during the drying process, reduces heat loss, and improves drying efficiency. The rotating frame 4 is mounted on the fixed rod 2. The drying rack 9 has two placement slots for placing the display screen. Rubber gaskets are embedded in the placement slots to prevent damage to the display screen during the drying process and reduce heat conduction loss.

[0028] The transmission components include a fixed gear 3 fixedly mounted on a fixed rod 2, a transmission rod 10 rotatably mounted on a fixed frame 5 and connected to the fixed rod 2, and a transmission gear 11 fixedly mounted on the transmission rod 10 and meshing with the fixed gear 3, and a rotating rod 7 rotatably mounted on the fixed frame 5 and integrally connected to the upper end of the drying rack 9 and connected to the transmission rod 10.

[0029] A conveyor belt is connected between the rotating rod 7 and the transmission rod 10 via a pulley. The conveyor belt is a synchronous belt to ensure that the rotating rod 7 and the transmission rod 10 rotate synchronously. A rotating rod 8 is rotatably mounted on the fixed frame 6 and is integrally connected to the lower end of the drying rack 9. Through the transmission action of the transmission component, the rotating frame 4 drives the drying rack 9 to rotate itself.

[0030] The rotating rod 7 is vertically positioned and extends above the fixed frame 5, while the fixed gear 3 is horizontally positioned above the rotating frame 4.

[0031] The clamp structure includes a clamp frame 14 fixedly installed on the drying rack 9, and a lifting rod 15 that limits the limiting block 13 is slidably sleeved inside the clamp frame 14. A moving block 16 is fixedly installed on the lifting rod 15, and a spring 17 that cooperates with the lifting rod 15 is welded between the moving block 16 and the clamp frame 14. The spring 17 provides a reset force for the lifting rod 15 to ensure that the lifting rod 15 stably limits the limiting block 13.

[0032] The limiting block 13 has a limiting hole corresponding to the lifting rod 15. The size of the limiting hole matches the lifting rod 15 to ensure that the lifting rod 15 is accurately inserted into the limiting hole to achieve the limiting. A lever is fixedly installed on the upper end of the lifting rod 15. The lever facilitates the operator to manually control the movement of the lifting rod 15.

[0033] It should be noted that the specific models and specifications of the controller, drive motor, and electric dryer 18 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0034] The functional principle of this utility model can be explained through the following operation methods:

[0035] Open the sealing door on the drying oven 1 corresponding to the discharge hole. Move the lever at the upper end of the lifting rod 15 in the traction clamp structure. The lever moves the moving block 16 through the lifting rod 15 to press the spring 17, causing the lifting rod 15 to disconnect from the limit block 13. The traction limit frame 12 opens. Place the display screen to be dried into the placement slot on the drying rack 9. Close the limit frame 12 and release the lever. The spring 17 moves the lifting rod 15 through the moving block 16 to insert it into the limit hole on the limit block 13, limiting the limit block 13 and completing the loading of the display screen.

[0036] The controller sends start commands to the drive motor and the electric dryer 18, and adjusts the output power of the electric dryer 18 to achieve a suitable drying temperature.

[0037] The output of the drive motor drives the rotating frame 4 to rotate. The rotating frame 4 drives the transmission rod 10 and the rotating rod 8 to rotate synchronously through the fixed frame 1 5 and the fixed frame 2 6 respectively. When the fixed frame 1 5 drives the transmission rod 10 to rotate, the transmission gear 11 on the transmission rod 10 meshes with the fixed gear 3. The transmission rod 10 drives the rotating rod 7 to rotate synchronously through the conveyor belt. The rotating rod 7 drives the drying rack 9 to rotate. At this time, while the fixed frame 1 5 and the fixed frame 2 6 drive the drying rack 9 to revolve around the fixed rod 2, the drying rack 9 itself drives the display screen to rotate.

[0038] The electric heating dryer 18 inside the drying chamber 1 continuously dries the rotating display screen. After the drying operation is completed, the controller sends a shutdown command to the drive motor and the electric heating dryer 18. The above steps are repeated to open the limit frame 12 and remove the dried display screen from the placement slot, thus completing the drying operation of the display screen.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
