Description

Technical Field

[0001] This utility model relates to the field of OLED material preparation technology, specifically to a novel OLED material reaction feeding device. Background Technology

[0002] OLED (Organic Light Emitting Diode) technology, which began in the 1960s, has undergone a leapfrog development from laboratory research to commercial applications. In 1987, the team led by Ching W. Tang at Kodak in the United States first achieved a low-voltage driven OLED device through vacuum evaporation technology, marking a crucial step towards the practical application of OLED technology. In recent years, with the rise of inkjet printing technology, the cost of OLED material preparation has significantly decreased, but vacuum evaporation technology still dominates the production of small and medium-sized AMOLED displays and large-sized WOLED displays due to its high precision advantage.

[0003] Currently, in existing technologies, some devices require manual switching between different raw material tanks for feeding, which cannot meet the needs of continuous and automated production. Among them, air-sensitive OLED intermediates (such as metal complex precursors) are prone to oxidation and deterioration, affecting product purity. Direct injection of multiple raw materials into the reaction device can easily lead to excessively high local concentrations and the generation of by-products. Therefore, a novel OLED material reaction feeding device is proposed. Utility Model Content

[0032] Please see Figure 1-7 This utility model proposes a novel OLED material reaction feeding device, including a base 1, a connecting plate 2 fixedly connected to the top left side of the base 1, a vertical plate 3 fixedly connected to the top of the connecting plate 2, a housing 4 fixedly connected to the left side of the vertical plate 3, a moving component 5 for feeding material on the left side of the housing 4, and a flipping component 6 for feeding material and flipping.

A vertical rod 10 is fixedly connected to the top of the horizontal plate 9. A horizontal plate 11 is fixedly connected to the top of the vertical rod 10. A rotating assembly 12 for feeding different feeding tanks is provided on the top of the horizontal plate 11. The rotating assembly 12 includes a motor 121. The motor 121 is mounted on the bottom plate of the horizontal plate 11. The output shaft of the motor 121 is connected to a gear 122. The gear 122 meshes with a gear 123. A horizontal plate 3 is fixedly connected to the inner wall of the gear 123. 124, the third horizontal plate 124 is rotatably connected to the top of the second horizontal plate 11 via bearings, and the tank switching is realized by the rotating assembly 12. The top of the third horizontal plate 124 is fixedly connected to the fixing frame 13, and the inner wall of the fixing frame 13 is inserted with a storage tank 14. There are four storage tanks 14, which are located in the four directions of the fixing frame 13. Since the storage tanks 14 are snapped into the inner wall of the fixing frame 13, they can be disassembled and replaced with sealed tanks, which are suitable for the reaction and feeding of liquids in specific environments. The top of the storage tank 14 is provided with a feed hopper, and both the feed hopper and the bottom of the storage tank 14 are provided with valves.

[0036] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that each electrical appliance can work normally. For example, motor 1 51 and motor 2 121 are both connected to the mains power. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0037] In this invention, during use, the feeding box 58 is initially loaded with raw materials through the top inlet, the cover is closed, and the side outlet valve is shut off to prepare for feeding. Motor 51 starts, and its output shaft drives the worm gear 52 to rotate. Since the worm gear 52 meshes with the worm wheel 53, the rotation of the worm gear 52 drives the worm wheel 53 to rotate synchronously. The threaded rod 54 fixedly connected to the inner wall of the worm wheel 53 rotates accordingly, causing the threaded block 55 to move upwards along the threaded rod 54. The threaded block 55 drives the circular plate 56, which is rotatably connected to it, the lifting plate 57 fixed to the left side of the circular plate 56, and the feeding box 58 to rise together. The abutment block 62 stabilizes the rising process. When the circular plate 56 rises to a predetermined height, the first tooth 63 on the outer wall of the circular plate 56 gradually meshes with the second tooth 64 on the right side of the fixed plate 61. Under the interaction of the two, the circular plate 56 drives the lifting plate 57 and the feeding box 58 to rotate at a certain angle. After the material is rotated into position, the discharge valve on the side of the feeding tank 58 is opened, and different types of OLED liquid reaction materials are injected into the tank through the feed hopper at the top of the storage tank 14. If different storage tanks 14 need to be fed, motor 2 121 is started, and its output shaft drives gear 1 122 to rotate. Gear 1 122 meshes with gear 2 123, transmitting power to gear 2 123, causing gear 2 123 to rotate the storage tank 14 at the top of the horizontal plate 3 124 by 90 degrees, completing the loading of raw materials. Then the valve at the bottom of the feed hopper is closed. After the feeding is completed, motor 1 51 reverses, and threaded block 55 drives circular plate 56, lifting plate 57 and feeding tank 58 to descend and reset. Circular plate 56 returns to its initial state, and the discharge valve of feeding tank 58 is closed. In specific reaction scenarios with high requirements for sealing environment, storage tank 14 can be replaced with a sealed tank, and the entire system can be purged with inert gas such as nitrogen through inclined pipe 15 and vertical pipe 16 to replace the internal air and prevent the raw materials from oxidizing or getting damp. Once the target storage tank 14 reaches the designated position, its bottom valve is opened, and the raw material is transported to the subsequent processing stage through the vertical pipe 16 connected to the bottom of the storage tank 14. If the raw material needs to be premixed, the storage tank 14 to be mixed is positioned at the top of the inclined pipe 15 by rotating the assembly 12, and the liquid enters the premixing chamber 17 through the inclined pipe 15. After mixing is completed, the bottom valve of the premixing chamber 17 is opened, and the material is then transported to the subsequent processing stage through the pipeline.
