Description

Technical Field

[0001] This utility model belongs to the technical field of centrifugal degassing machines for adhesive production, and particularly relates to a centrifugal degassing machine for OLED display encapsulation adhesive production. Background Technology

[0002] Centrifugal degassing machines used in adhesive production generate centrifugal force through high-speed rotation to separate air bubbles in the adhesive, improving the uniformity and flowability of the adhesive. They are key equipment in adhesive production. OLED display encapsulation has extremely high requirements for the non-foaming and purity of the adhesive. Tiny air bubbles can affect display quality and reliability. Therefore, this equipment has become a core component in OLED encapsulation adhesive production to ensure that the adhesive meets the standards.

[0003] Currently, existing centrifugal degassing machines for glue production require the glue buckets to be removed after centrifugation and then new glue buckets to be placed in the centrifugation position. This involves many steps and greatly reduces centrifugation efficiency.

[0004] Therefore, we propose a centrifugal degassing machine for OLED display encapsulation adhesive production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the installation and disassembly steps of glue buckets are cumbersome and reduce centrifugal efficiency in the existing technology, and to propose a centrifugal degassing machine for the production of OLED display encapsulation glue.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A centrifugal degassing machine for producing OLED display encapsulating adhesive includes a centrifugal degassing machine body, and a discharge mechanism is provided on the outside of the centrifugal degassing machine body;

[0008] The unloading mechanism includes two semi-cylinders. A hydraulic rod is fixedly connected to the inner bottom wall of each semi-cylinder. A circular plate is fixedly connected to the telescopic end of each hydraulic rod. A circular ring is provided on the outer side of each semi-cylinder. Two sets of transmission plates are fixedly connected to the other side of each circular ring. Four sets of force springs are fixedly connected to the outer surface of the centrifugal degassing machine body. Each set of force springs consists of two springs. A connecting plate is fixedly connected to one end of each force spring. A moving block is fixedly connected to the side of each pair of connecting plates that are close to each other.

[0009] Preferably, a long shaft is rotatably connected to the inner wall of the centrifugal degassing machine body, and a tilting plate is fixedly connected to the outer surface of the long shaft, with the bottom surface of the tilting plate in contact with the upper surface of the centrifugal degassing machine body.

[0010] Preferably, a control box is fixedly connected to the front of the centrifugal deaerator body, and a controller is fixedly connected to the inner side wall of the control box. The controller is electrically connected to two hydraulic rods respectively through wires.

[0011] Preferably, the control box has a hinged door on its front, and a pull handle is fixedly connected to the front of the door.

[0012] Preferably, a trigger button is fixedly connected to the inner wall of the centrifugal deaerator body, the top of the trigger button is in contact with the bottom surface of the tilting plate, and the trigger button is electrically connected to the controller through a wire.

[0013] Preferably, each of the circular rings has several identical positioning shafts fixedly connected to its bottom surface, and the outer surface of each positioning shaft is slidably connected to the inside of the semi-cylinder.

[0014] Preferably, the inner wall of each of the moving blocks is rotatably connected to a first roller and a second roller, and one side of each of the circular rings is in contact with one end of the semi-cylinder.

[0015] Preferably, a fixing frame is fixedly connected to the inner wall of the centrifugal degassing machine body, and the outer surface of the fixing frame is fixedly connected to the outer surface of the two semi-cylinders.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] By setting up the centrifugal degassing machine body, the operator can place the glue bucket to be centrifuged into the two rotating cylinders inside the machine body. Under the action of gravity, the glue bucket will fall onto the surface of four moving blocks, and then centrifugation will begin. After the glue has been centrifuged, the operator needs to open the tilting plate. When the operator opens the tilting plate, the tilting plate will stop pressing the trigger button. Therefore, the trigger button will transmit information to the controller via an electrical signal. The controller will also transmit information to the hydraulic rod via an electrical signal. The hydraulic rod will push the circular plate into the interior of the centrifugal degassing machine body. During the movement, the circular plate will contact the surface of the circular ring. Therefore, the circular plate will push the circular ring to move synchronously. The circular ring will push the transmission plate into the interior of the moving blocks. The transmission plate will push the moving blocks away from the glue bucket. Therefore, the glue bucket will continue to fall under the action of gravity until it falls onto the surface of the circular plate. Then, the hydraulic rod will be controlled to reset, thus achieving the purpose of automatically removing the centrifuged glue and increasing the centrifugation rate of the glue.

[0024] 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.

[0025] Reference Figure 1 and Figure 2 A centrifugal degassing machine for OLED display encapsulation adhesive production includes a centrifugal degassing machine body 1. A discharge mechanism 2 is provided on the outside of the centrifugal degassing machine body 1. The discharge mechanism 2 includes two semi-cylinders 201. A long shaft 6 is rotatably connected to the inner wall of the centrifugal degassing machine body 1. A flip plate 7 is fixedly connected to the outer surface of the long shaft 6. The bottom surface of the flip plate 7 is in contact with the upper surface of the centrifugal degassing machine body 1. By providing the long shaft 6 and the flip plate 7, the flip plate 7 can be rotated around the long shaft 6, which makes it convenient to place the glue bucket to be centrifuged into the interior of the centrifugal degassing machine body 1.

[0026] Reference Figures 1-4 Each semi-cylindrical cylinder 201 has a hydraulic rod 202 fixedly connected to its inner bottom wall. A control box 5 is fixedly connected to the front of the centrifugal degassing machine body 1. A controller 8 is fixedly connected to the inner side wall of the control box 5. The controller 8 is electrically connected to the two hydraulic rods 202 respectively through wires. By setting up the controller 8, the controller 8 can control the various electronic devices, making the operation of the various electronic devices more stable.

[0027] Reference Figures 3-5Each hydraulic rod 202 has a circular plate 206 fixedly connected to its telescopic end, and a circular ring 203 is provided on the outer side of each semi-cylinder 201. A movable door 4 is movably hinged to the front of the control box 5, and a pull handle 3 is fixedly connected to the front of the movable door 4. By providing the pull handle 3 and the movable door 4, the pull handle 3 can be used to apply a pulling force to the movable door 4, making it convenient to open the movable door 4.

[0028] Reference Figure 2 and Figure 5 Two sets of transmission plates 205 are fixedly connected to the other side of each circular ring 203. Four sets of force springs 209 are fixedly connected to the outer surface of the centrifugal deaerator body 1. There are two force springs in each set. A connecting plate 208 is fixedly connected to one end of each force spring 209. A trigger button 9 is fixedly connected to the inner wall of the centrifugal deaerator body 1. The top of the trigger button 9 is in contact with the bottom surface of the flip plate 7. The trigger button 9 is electrically connected to the controller 8 through a wire. The trigger button 9 can be used to detect whether the centrifugal deaerator body 1 has been opened.

[0029] Reference Figure 4 and Figure 5 Each pair of connecting plates 208 has a moving block 207 fixedly connected to one side that is close to each other. Each circular ring 203 has several identical positioning shafts 10 fixedly connected to its bottom surface. The outer surface of each positioning shaft 10 is slidably connected to the inside of the semi-cylinder 201. By setting the positioning shafts 10, the movement position of the circular ring 203 can be limited.

[0030] Reference Figure 5 Each moving block 207 has a first roller 11 and a second roller 12 rotatably connected to its inner wall. One side of each circular ring 203 is in contact with one end of the semi-cylinder 201. By providing the first roller 11 and the second roller 12, the presence of the first roller 11 can prevent the surface of the glue bucket from being subjected to excessive friction when it is disassembled, while the presence of the second roller 12 can prevent the surface of the transmission plate 205 from being subjected to excessive friction.

[0031] Reference Figure 3 A fixing frame 204 is fixedly connected to the inner wall of the centrifugal degassing machine body 1. The outer surface of the fixing frame 204 is fixedly connected to the outer surface of the two semi-cylinders 201. By setting the fixing frame 204, the two semi-cylinders 201 can be fixed, making the two semi-cylinders 201 more stable.

[0032] The working principle of this utility model is as follows: During use, the operator can place the glue bucket to be centrifuged into the two rotating cylinders inside the centrifugal degassing machine body 1. Under the action of gravity, the glue bucket will fall onto the surface of the four moving blocks 207, and then centrifugation will begin. After the glue has been centrifuged, the operator needs to open the tilting plate 7. When the operator opens the tilting plate 7, the tilting plate 7 will stop pressing the trigger button 9. Therefore, the trigger button 9 will transmit information to the controller 8 via an electrical signal. The controller 8 will also transmit information to the hydraulic rod 202 via an electrical signal. It should be understood that each time the operator opens the tilting plate 7, the trigger button 9 will be triggered, and the hydraulic rod 202 will push the circular plate 206 into the interior of the centrifugal degassing machine body 1. During the movement, the circular plate 206 will interact with the circular... The circular plate 206 synchronously pushes the circular ring 203 to move because the circular ring 203 contacts the surface of the ring 203. The circular ring 203 pushes the transmission plate 205 into the interior of the moving block 207. The transmission plate 205 pushes the moving block 207 away from the glue bucket. As a result, the glue bucket continues to fall under the action of gravity until it falls onto the surface of the circular plate 206. Then, the hydraulic rod 202 is reset, and the glue bucket that has been centrifuged will move with the circular plate 206. Therefore, after the operator opens the flip plate 7, they only need to place a new batch of glue buckets into the interior of the centrifugal degassing machine body 1. Then, the operator closes the flip plate 7 to start a new centrifugation operation. At this time, the operator can take out the glue bucket that has been centrifuged from the interior of the semi-cylinder 201. Therefore, the purpose of increasing the centrifugation rate of the glue can be achieved.
