Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a novel OLED material drying equipment. Background Technology

[0002] In flat panel display technology, organic light-emitting diode (OLED) displays are widely recognized by the industry as the third generation of display technology after liquid crystal displays (LCDs) due to their numerous advantages such as thinness, active light emission, fast response speed, wide viewing angle, rich colors, high brightness, low power consumption, and resistance to high and low temperatures. Drying is an essential process in the production of OLED organic materials.

[0003] Currently, in existing technologies, such as Chinese patent CN207815903U, an OLED organic material drying device is disclosed. This device has a dispersing device on a supporting device, and a steam absorption device on the inner wall of the drying chamber located above the supporting device. The condenser, electric heating device, and steam absorption device are all electrically connected to the control device. The advantages are that the structure is simple and the design is reasonable. It can effectively control the temperature in the drying chamber and the drying time of the OLED organic material, reduce energy consumption, and save energy. At the same time, the dried OLED organic material cools down quickly so that it can be carried out in the next process, and the production efficiency is significantly improved.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. First, most OLED materials cannot be broken up during the drying process, otherwise the material structure will be easily damaged. It cannot effectively increase the heating area by spreading the materials flat, and the material accumulation requires breaking them up. It is also difficult to load and unload the materials, and it is inconvenient to remove the materials after drying. Its practicality needs to be improved, which affects the drying efficiency. In addition, the air inlet is singular, which means that the hot air cannot evenly fill the entire internal space of the oven, and the hot air cannot fully exchange heat with the OLED materials. In view of this, we propose a new type of OLED material drying equipment. Utility Model Content

[0005] The purpose of this invention is to provide a novel OLED material drying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel OLED material drying device includes an oven, a transparent cover fixedly installed on the top of the oven, a controller fixedly installed on the outer wall of the bottom of the oven, and a drying assembly disposed on the oven, the drying assembly comprising:

[0008] The oven is equipped with a slide rail, on which a sliding box is slidably mounted. A material box is fitted inside the sliding box. A handle is fixedly mounted in the middle of the end of the sliding box away from the oven, and a grip is fixedly mounted at the top inside the material box.

[0009] A rectangular plate is fixedly installed at the bottom of the sliding box at the end away from the oven. Rollers are provided at the bottom of the rectangular plate. A blower is provided outside the oven. The input end of the blower is fixedly connected to the output end of the heating unit. The output end of the blower is fixedly connected to the input end of the three-headed pipe. The output end of the three-headed pipe is fixedly connected to one end of the bent pipe.

[0010] A horizontal tube is formed, with one end of the curved tube fixedly connected to the other end of the horizontal tube. An air outlet pipe is fixedly installed at the other end of the horizontal tube. The air outlet pipe is fixedly installed inside the side wall of the oven and is connected to the inside of the oven. A through slot is provided at the center of the top of the transparent cover.

[0011] In a further embodiment, the transparent cover is made of high-temperature resistant transparent glass, thereby allowing for better observation of the drying process of the materials inside the oven.

[0012] In a further embodiment, the slide rail, handle, and rollers are provided in two sets, and both sets of slide rail, handle, and rollers are mirror images of the vertical center line of the oven, positioned at both ends of the oven. This makes the movement of the sliding box more stable, and the handle facilitates the picking and placing of the material box.

[0013] In a further embodiment, the curved pipe and the horizontal pipe are provided in two sets, and the air outlet pipe on each set of the horizontal pipe is provided in multiple sets, and the multiple sets of air outlet pipes are arranged in a linear array at equal intervals, so that the hot airflow can fill the entire interior of the oven more evenly and quickly.

[0014] In a further embodiment, the oven is also equipped with an auxiliary component, which includes an L-shaped frame. One end of the L-shaped frame is fixedly connected to the outer wall of the transparent cover, and a small hydraulic cylinder is fixedly installed at the other end of the L-shaped frame. The bottom of the piston end of the small hydraulic cylinder is fixedly connected to the top center of the arc-shaped plate. The arc-shaped plate is located directly above the through groove, and the arc-shaped inner wall of the arc-shaped plate slides against the arc-shaped outer wall of the transparent cover, thereby better sealing the through groove.

[0015] In a further embodiment, an axial flow fan is fixedly installed at the center of the top of the oven, and the axial flow fan is located directly below the through slot, so that the airflow can be better circulated.

[0016] In a further embodiment, a temperature sensor is fixedly installed inside the oven, and multiple sets of temperature sensors are provided to better display temperature data and control the operation of other structures through the controller.

[0017] Compared with the prior art, this utility model provides a novel OLED material drying equipment, which has the following beneficial effects:

[0018] 1. This new OLED material drying equipment, in order to better dry OLED materials and facilitate loading and unloading, is equipped with drying components. After the OLED material is laid flat inside the material box, the handle is held to place the material box into the sliding box. The handle is held to slide the sliding box into the oven along the slide rail. The rectangular plate makes the rollers rotate synchronously, which plays a role in stability and support. When the heating machine is started, the blower injects hot air into the oven through the three-head pipe, the curved pipe, the horizontal pipe and the air outlet pipe. Multiple sets of air outlet pipes make the hot air more even and quickly fill the entire oven. The air is discharged from the through slot, which makes the OLED material heat more evenly, the drying effect better, and facilitates loading and unloading.

[0019] 2. To enhance the practicality of this new OLED material drying equipment, auxiliary components are incorporated. When the small hydraulic cylinder on the L-shaped frame is activated, the curved plate moves up and down. When the curved plate moves downwards and presses against the curved outer wall of the transparent cover, it seals the passageway, allowing hot airflow to remain inside the oven and fully heat and dry the material. Conversely, when the curved plate moves upwards away from the transparent cover, the axial flow fan expels the airflow from inside the oven. Multiple temperature sensors monitor the oven's internal temperature in real time, enabling better display of temperature data and control of other components via the controller. In summary, this significantly improves the equipment's practicality. Attached Figure Description

It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] A novel OLED material drying device includes an oven 1, a transparent cover 2 fixedly installed on the top of the oven 1, and the transparent cover 2 is made of high temperature resistant transparent glass material to better observe the drying of the material inside the oven 1. A controller 3 is fixedly installed on the outer wall at the bottom of the oven 1.

[0033] In one embodiment of this utility model, a drying component 4 is provided on the oven 1. The drying component 4 includes a slide rail 41. The slide rail 41 is provided inside the oven 1. A sliding box 42 is slidably mounted on the slide rail 41. A material box 43 is sleeved inside the sliding box 42. A handle 44 is fixedly installed at the middle of the end of the sliding box 42 away from the oven 1. A grip 45 is fixedly installed at the top of the material box 43. A rectangular plate 46 is fixedly installed at the bottom of the end of the sliding box 42 away from the oven 1. A roller 47 is provided at the bottom of the rectangular plate 46. In addition, there are two sets of slide rails 41, grips 45 and rollers 47. Both sets of slide rails 41, grips 45 and rollers 47 are mirror images of the vertical center line of the oven 1 and are mirror images of the two ends of the oven 1. This makes the movement of the sliding box 42 more stable and facilitates retrieval with the grip 45. A material box 43 is placed inside the oven 1. An air blower 48 is installed outside the oven 1. The input end of the air blower 48 is fixedly connected to the output end of the heating unit 49. The output end of the air blower 48 is fixedly connected to the input end of the three-head pipe 410. The output end of the three-head pipe 410 is fixedly connected to one end of the bent pipe 411. The other end of the bent pipe 411 is fixedly connected to one end of the horizontal pipe 412. An air outlet pipe 413 is fixedly installed on the other end of the horizontal pipe 412. The air outlet pipe 413 is fixedly installed inside the side wall of the oven 1 and is connected to the inside of the oven 1. In addition, there are two sets of bent pipes 411 and horizontal pipes 412. There are ten sets of air outlet pipes 413 on each set of horizontal pipes 412. The ten sets of air outlet pipes 413 are arranged in a linear array with equal spacing, so that the hot airflow fills the entire interior of the oven 1 more evenly and quickly. A through slot 414 is opened at the center of the top of the transparent cover 2.

[0034] In this embodiment, the operator places the OLED material flat inside the material box 43. This flat placement maximizes the contact area between the material and the hot airflow, laying the foundation for uniform drying. Then, holding the handle 45 at the top of the material box 43, the operator inserts it into the inner cavity of the sliding box 42. The handle 45 is designed for easy operation. Holding the handle 44 at the end of the sliding box 42, the operator pushes the sliding box 42 into the oven 1 under the guidance of the slide rail 41. At this time, the rectangular plate 46 at the bottom of the sliding box 42 drives the rollers 47 to roll. The cooperation between the rollers 47 and the rectangular plate 46 not only reduces movement resistance but also ensures the sliding box 42 remains balanced during movement through the two symmetrically arranged slide rails 41 and rollers 47. Simultaneously, the rollers 47 also bear the weight of the material. When the heating element 49 is started, it generates high... Warm airflow is simultaneously activated by the blower 48. The rotation of the blower 48 impeller draws in the hot airflow and pressurizes it for transport. The hot airflow is then distributed sequentially through the three-head pipe 410, the bend pipe 411 changes its direction, and the horizontal pipe 412 further distributes it. Finally, it is output to the interior of the oven 1 through the exhaust pipe 413. Ten sets of equally spaced exhaust pipes 413 form a matrix airflow output, ensuring that the hot airflow fills the entire oven 1 space with a uniform flow rate and temperature. After the hot airflow fully exchanges heat with the OLED material, it is discharged through the through slot 414 at the top of the transparent cover 2. Due to the uniform distribution of the hot airflow in the oven 1, the temperature difference between different parts of the material is small, ensuring the consistency of the OLED material performance after drying. Furthermore, the entire loading and unloading process is facilitated by the cooperation of the handle 44 and the slide rail 41, allowing for quick removal of the material box 43 and completing one loading or unloading operation, thereby improving drying efficiency.

[0035] In one embodiment of this utility model, the oven 1 is further provided with an auxiliary component 5, which includes an L-shaped frame 51. One end of the L-shaped frame 51 is fixedly connected to the outer wall of the transparent cover 2, and a small hydraulic cylinder 52 is fixedly installed at the other end of the L-shaped frame 51. The bottom of the piston end of the small hydraulic cylinder 52 is fixedly connected to the top center of the arc plate 53. The arc plate 53 is located directly above the through groove 414. The arc-shaped inner wall of the arc plate 53 slides against the arc-shaped outer wall of the transparent cover 2, thereby better sealing the through groove 414. In addition, the top center of the oven 1 is fixedly... An axial flow fan 54 is fixedly installed below the through slot 414, which allows for better airflow. It is worth noting that the axial flow fan 54 is a certain distance away from the material inside the oven 1, and the airflow of the axial flow fan 54 is relatively small, so it will not suck up the material. In addition, four temperature sensors 55 are fixedly installed inside the oven 1, and the four sets of temperature sensors 55 are located at the four corners inside the oven 1, so as to better display temperature data through the controller 3 and control the operation of other structures.

[0036] In this embodiment, when it is necessary to extend the residence time of the hot airflow in the oven 1, the small hydraulic cylinder 52 on the L-shaped frame 51 is activated, and its piston end extends downward, pushing the arc plate 53 to press against the arc-shaped outer wall of the transparent cover 2. The inner wall of the arc plate 53 is tightly fitted with the outer wall of the transparent cover 2, forming a sealing structure and completely blocking the through groove 414. At this time, the hot airflow fully dries the material, and the blower 48 and the heater 49 are stopped, thereby saving costs. When the piston end of the small hydraulic cylinder 52 retracts, it drives the arc plate 53 to move upward away from the transparent cover 2, and the through groove 414 opens. At the same time, the axial flow fan 54 is activated to accelerate the discharge of high-temperature gas in the oven 1 through the through groove 414. The four sets of temperature sensors 55 distributed in the four corners of the oven 1 transmit temperature signals to the controller 3. The display screen of the controller 3 displays the monitoring data of each temperature sensor 55 in real time. The operator can set the drying program parameters through the touch interface to control other electrical components.

[0037] All electrical components mentioned in this application are electrically connected to the controller 3 and the 220V mains power. The controller 3 is a conventional and known device that can control the blower 48, the heater 49, the small hydraulic cylinder 52, the axial flow fan 54, and the temperature sensor 55. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
