Description

Technical Field

[0001] The present invention belongs to the technical field of OLED packaging, and in particular relates to multi-station OLED packaging equipment and an operating method thereof. Background Art

[0002] OLED encapsulation equipment is a special equipment used to protect organic light-emitting diode (OLED) devices from environmental influences, ensuring their lifespan and performance; it uses a metal cover plate and thermally cured adhesive to complete the encapsulation operation.

[0003] Traditional OLED packaging equipment typically uses a single-station linear production model, where process steps such as substrate pretreatment, packaging material coating, and substrate and cover alignment must be completed sequentially at a single station. This design has the following inherent flaws: Because each process is executed serially, when the current station is performing a process, the other stations are idle, resulting in a high equipment idle rate and difficulty in increasing overall production capacity; each process requires independent equipment (such as cleaning machines, coating machines, alignment platforms, etc.), which not only occupies a large area, but also has no-load energy consumption when multiple devices operate in coordination, resulting in poor cost-effectiveness; in the traditional cleaning process, the inlet and outlet of the UV-ozone cleaning machine lack a dynamic sealing mechanism, which is easily affected by external contamination during the cleaning process, requiring additional cleaning time or repeated processes, further reducing production efficiency.

[0004] While existing technologies attempt to increase production capacity by connecting multiple devices in parallel, they fail to address the issue of coordinated material flow between processes. In particular, sealing defects in the cleaning process prevent a balance between cleaning effectiveness and transfer efficiency. Therefore, there is an urgent need for an integrated multi-station packaging device that can parallelize processes in a compact space and ensure sealing reliability in the critical cleaning process.

[0011] Preferably, the length of the sealing plate is greater than the length of the inlet and outlet of the UV-ozone cleaning machine, and the width of the sealing plate is consistent with the distance between the top of the UV-ozone cleaning machine and the conveyor belt.

[0012] The operating method of the multi-station OLED packaging equipment comprises the following steps:

[0013] S1. Cleaning process of substrate and packaging plate: The conveyor belt transports the substrate and packaging plate respectively, and their synchronous movement is controlled by PLC; when the laser sensor detects that the substrate and packaging plate enter the inlet area of ​​the UV-ozone cleaning machine 501, it sends a signal to the PLC, and the PLC immediately stops the conveyor belt to ensure that the materials are accurately positioned at the cleaning station; the PLC starts the dual-axis motor to drive the disc to rotate, and the round block on the outside of the disc slides in the rectangular groove, forcing the rectangular plate to move vertically downward along the limit block; the rectangular plate drives the sealing plate downward through the connecting round block, and the vertical plate at the bottom of the sealing plate first contacts the surface of the conveyor belt, and then the long plate is squeezed and compressed back into the slide groove, and the telescopic spring is compressed and deformed, so that the sealing plate is completely fitted with the inlet and outlet of the UV-ozone cleaning machine to form an airtight seal; the UV-ozone cleaning machine is started to clean the surfaces of the substrate and packaging plate in the sealed space;

[0014] S2. Post-cleaning material flow and parallel processing: After cleaning is completed, the dual-axis motor reverses, and the disc drives the sealing plate to rise and reset, releasing the seal. The conveyor belt restarts, transporting the cleaned substrate and packaging plate to the packaging area. At the same time, subsequent materials to be cleaned are synchronously fed into the UV-ozone cleaning machine, achieving continuous operation of the cleaning station.

[0015] S3. Positioning and gluing the packaging board: Linear module 1 drives the positioning rod along the X-axis, while linear module 2 drives positioning plate 1 along the Y-axis, aligning the center of the gluing device's fixed ring with the edge of the packaging board. Three linear modules 3 each push positioning plate 2 forward, keeping the gluing device's nozzle 5-10 mm from the packaging board surface. The three gluing devices are activated simultaneously, applying a 0.5 mm wide layer of sealant to the packaging board surface in a serpentine pattern.

[0016] S4, substrate adsorption and transfer: Linear module 2 403 and linear module 1 401 move in coordination to move the air pump 606 above the substrate. The air pump then drives the adsorption plate down to 1 mm above the substrate. The vacuum pump starts and sucks air from the adsorption holes through the air pipe, firmly adsorbing the substrate to the bottom surface of the adsorption plate. Linear module 2 and linear module 1 move in coordination to move the adsorbed substrate horizontally to the top of the encapsulation plate after the glue is applied.

[0017] S5. Precise pressing and packaging: The air pump pushes the adsorption plate downward at a pressure of 0.2MPa to evenly spread the sealant between the substrate and the packaging plate; the vacuum pump releases the adsorption, and the air pump lifts the adsorption plate to reset, completing a single packaging cycle.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The multi-station OLED packaging equipment of the present invention transports the substrate and packaging plate to the interior of the UV-ozone cleaning machine by setting a conveyor belt, and then rotates the disc to drive the sealing plate to move downward, and the sealing plate is used to seal its inlet and outlet, so that the material is cleaned by the UV-ozone cleaning machine, and the cleaned object is further transported to the next process through the conveyor belt, saving space and being easy to use.

[0020] 2. The multi-station OLED packaging equipment of the present invention transports the packaging plate and substrate to the appropriate position through a conveyor belt, and enables the gluing device to quickly move to the top of the packaging plate to position the packaging plate through linear module 1 and linear module 2, and then sealant is applied to the packaging plate at the same time through multiple gluing devices, thereby improving the packaging efficiency.

[0021] 3. The multi-station OLED packaging equipment of the present invention drives the adsorption plate to contact the substrate through an air pump, and then uses a vacuum pump to extract the air in the adsorption hole to adsorb the substrate, and then squeezes the substrate and the packaging plate against each other to perform the packaging operation, thereby avoiding warping or deviation of the substrate, ensuring close fit with the packaging plate, eliminating bubbles through uniform pressure distribution, and improving the packaging effect.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 9 As shown, an embodiment of the present invention provides a multi-station OLED packaging device and an operating method thereof, including a platform 1, a transport platform 2 is provided on the inner side of the platform 1, a transport belt 3 is provided above the transport platform 2, a positioning mechanism 4 is provided above the platform 1, and a cleaning mechanism 5 is provided above the transport belt 3. The cleaning mechanism 5 includes a UV-ozone cleaning machine 501 bolted to both sides of the transport platform 2, an inlet 518 and an outlet 519 are provided on both sides of the UV-ozone cleaning machine 501, the top of the UV-ozone cleaning machine 501 is located above the transport belt 3, and a box 502 is installed on the top bolt of the UV-ozone cleaning machine 501. A rectangular block 511 is welded inside the box 502, and the front of the rectangular block 511 is welded to the front of the rectangular block 511. Discs 513 are provided on the rear two sides, and a dual-axis motor 512 is installed on the internal bolts of the rectangular block 511, and the output ends of the dual-axis motor 512 are bolted to the inner sides of the discs 513 on both sides; rectangular plates 514 are slidably installed on the front and back sides of the interior of the box body 502, and a rectangular groove 515 is provided on the inner side of the rectangular plate 514, and a round block 517 located inside the rectangular groove 515 is welded on the outer side of the disc 513; vertical grooves 503 are provided on the front and back sides of the box body 502, and a connecting round block 510 that can slide up and down inside the vertical groove 503 is welded on the outer side of the rectangular plate 514, and a connecting block 505 is welded on the outer side of the connecting round block 510, and a sealing plate 504 located on the outer side of the box body 502 is welded to the bottom of the connecting block 505.

[0034] Among them, the rectangular plate 514 is slidably connected to the limit blocks 516 on the left and right sides, and the two limit blocks 516 are welded to the inside of the box 502; when the rectangular plate 514 moves up and down on the inner side of the limit blocks 516, the limit blocks 516 are used to assist in limiting the rectangular plate 514 to prevent the rectangular plate 514 from deflecting and affecting its normal operation.

[0035] like Figures 1 to 9 As shown, a sliding groove 506 is formed inside the sealing plate 504, and a long plate 507 is slidably mounted inside the sliding groove 506. A vertical plate 508 extending below the sealing plate 504 is welded to the bottom of the long plate 507. A telescopic spring 509 is uniformly and elastically mounted between the upper side of the long plate 507 and the inner side of the sliding groove 506. The length of the sealing plate 504 is greater than the length of the inlet and outlet of the UV-ozone cleaning machine 501, and the width of the sealing plate 504 is consistent with the distance between the top of the UV-ozone cleaning machine 501 and the conveyor belt. The vertical plate 508 and the sealing plate 504 seal the inlet and outlet of the UV-ozone cleaning machine 501, thereby improving the cleaning effect of the UV-ozone cleaning machine 501 and facilitating its use.

[0036] When in use, the substrate and the packaging plate are transported by the conveyor belt 3 (the two conveyor belts in the figure can transport the substrate and the packaging plate respectively). After the substrate and the packaging plate are transported to the inside of the box 502, the laser sensor (not shown in the figure) receives the signal and transmits it to the PLC. The PLC controls the conveyor belt 3 to stop running through the control panel and starts the dual-axis motor 512 at the same time, so that the dual-axis motor 512 drives the disc 513 to rotate, and the disc 513 drives the round block 517 to do a circular motion, so that the round block 517 drives the rectangular plate 514 to move downward inside the rectangular groove 515, so that the rectangular plate 514 passes through the connecting The connecting block 510 drives the connecting block 505 to move downward, so that the sealing plate 504 drives the vertical plate 508 to move downward. When the vertical plate 508 contacts the conveyor belt 3, the sealing plate 504 continues to move downward, so that the vertical plate 508 drives the long plate 507 to shrink to the inside of the slide groove 506. The long plate 507 squeezes the telescopic spring 509, and the telescopic spring 509 is deformed. The sealing plate 504 continues to move downward until it contacts the conveyor belt 3, thereby blocking the inlet and outlet of the UV-ozone cleaning machine 501. At this time, the substrate and packaging plate are cleaned by the UV-ozone cleaning machine 501.

[0037] The laser sensor determines whether the substrate and packaging plate have entered the interior of the UV-ozone cleaning machine 501, so that the disc 513 rotates to drive the sealing plate 504 to move downward, so that the sealing plate 504 seals the inlet and outlet of the UV-ozone cleaning machine 501. Compared with traditional OLED packaging equipment, this multi-station OLED packaging equipment transports the substrate and packaging plate to the interior of the UV-ozone cleaning machine 501 by setting a conveyor belt 3, and seals them with the sealing plate 504, so that the material is cleaned by the UV-ozone cleaning machine 501, and the cleaned object is continued to be transported to the next process through the conveyor belt 3, saving space and being easy to use.

[0038] like Figures 1 to 9 As shown, the positioning mechanism 4 includes a linear module 401 bolted above the platform 1, a positioning rod 402 is provided above the linear module 401, a linear module 2 403 is bolted above the positioning rod 402, a packaging mechanism 6 is provided above the linear module 2 403, the packaging mechanism 6 includes a plurality of positioning plates 601 provided above the linear module 2 403, a plurality of linear modules 3 602 (3 in this embodiment) are bolted to the front side of the positioning plate 1 601, a positioning plate 2 603 is provided on the front side of each linear module 3 602, a fixing ring 604 is bolted to the front end of each positioning plate 2 603, a gluing device 605 is installed to the internal bolt of each fixing ring 604, a plurality of air pumps 606 (3 in this embodiment) are bolted to the rear side of the positioning plate 1 601, the output end of each air pump 606 is vertically downward and is bolted to an adsorption plate 607.

[0039] At this time, the conveyor belt 3 continues to move to transport the substrate and the packaging plate to the specified position. At this time, the positioning rod 402 moves back and forth above the linear module 401 to position the X-axis direction, and the positioning plate 1 601 moves above the linear module 2 403 to position the Y-axis direction, thereby moving multiple glue coating devices 605 to the top of the corresponding packaging plate. When coating, the linear module 3 602 is started through the pre-set program of the controller, so that the linear module 3 602 drives the positioning plate 2 603 to move, and the sealant is coated on the surface of the packaging plate through multiple glue coating devices 605.

[0040] Compared with traditional OLED packaging equipment, linear module 1 401 and linear module 2 403 enable multiple glue coating devices 605 to quickly move to the corresponding packaging board to position the packaging board, and then multiple glue coating devices 605 are used to coat the surface of the packaging board with sealant, thereby improving the packaging efficiency.

[0041] like Figure 3As shown, adsorption holes 610 are evenly opened at the bottom of each adsorption plate 607, a vacuum pump 608 is installed on the rear bolt of each air pump 606, and an air pipe 609 is threadedly installed at the bottom of each vacuum pump 608. The other end of the air pipe 609 is threadedly installed on the top of the corresponding adsorption plate 607, and the air pipe 609 is adapted to the adsorption hole 610.

[0042] Among them, the air pump 606 is moved to the top of the substrate, and the air pump 606 is started, so that the air pump 606 drives the adsorption plate 607 to contact the substrate. At this time, the vacuum pump 608 is started, so that the vacuum pump 608 adsorbs the substrate through the air pipe 609 and the adsorption hole 610, thereby lifting the substrate, and then the substrate is moved to the top of the packaging plate, and the air pump 606 is started to squeeze the substrate and the packaging plate, thereby completing the packaging operation.

[0043] The adsorption plate 607 is driven to contact the substrate by the air pump 606, and then the air in the adsorption hole 610 is extracted by the vacuum pump 608, thereby adsorbing the substrate, and then encapsulating the substrate and the packaging plate. Compared with traditional OLED packaging equipment, this multi-station OLED packaging equipment adsorbs the substrate through the adsorption plate 607, and then squeezes the substrate and the packaging plate against each other for packaging operations, avoiding warping or deviation of the substrate, ensuring close fit with the packaging plate, eliminating bubbles through uniform pressure distribution, and improving the packaging effect.

[0044] Working principle and usage process:

[0045] S1. Substrate and packaging plate cleaning process: The conveyor belt 3 (including two sub-conveyor belts arranged in parallel) transports the substrate and the packaging plate respectively (the packaging plates can be placed at a certain distance through the set program to match the distance between multiple glue coating devices 605), and their synchronous movement is controlled by PLC; when the laser sensor detects that the substrate and the packaging plate enter the inlet area of ​​the UV-ozone cleaning machine 501, it sends a signal to the PLC, and the PLC immediately stops the operation of the conveyor belt 3 to ensure that the materials are accurately positioned at the cleaning station. The PLC starts the dual-axis motor 512 to drive the disc 513 to rotate. The round block 517 on the outside of the disc 513 slides in the rectangular groove 515, forcing the rectangular plate 514 to move vertically downward along the limit block 516; the rectangular plate 514 drives the sealing plate 504 to be pressed down by the connecting round block 510, and the vertical plate 508 at the bottom of the sealing plate 504 first contacts the surface of the conveyor belt 3, and then the long plate 507 is squeezed and compressed back into the slide groove 506, and the telescopic spring 509 is compressed and deformed, so that the sealing plate 504 is completely fitted with the inlet and outlet of the UV-ozone cleaning machine 501, forming an airtight closure; the UV-ozone cleaning machine 501 is started to clean the surface of the substrate and the packaging plate in the sealed space (the processing time can be preset to 30-60 seconds).

[0046] S2. Material flow and parallel processing after cleaning: After cleaning is completed, the dual-axis motor 512 reverses, and the disc 513 drives the sealing plate 504 to rise and reset, releasing the sealing state; the conveyor belt 3 restarts to transport the cleaned substrate and packaging plate to the packaging area, and at the same time, the subsequent materials to be cleaned enter the UV-ozone cleaning machine 501 synchronously, realizing continuous operation of the cleaning station.

[0047] S3. Positioning and gluing the packaging board: Linear module 1 401 drives the positioning rod 402 to move along the X-axis, and linear module 2 403 drives the positioning plate 1 601 to move along the Y-axis, so that the center of the fixing ring 604 of the gluing device 605 is aligned with the edge of the packaging board (positioning accuracy ±0.1mm); the three linear modules 3 602 respectively push the positioning plate 2 603 downward, so that the nozzle of the gluing device 605 is 5-10mm away from the surface of the packaging board; the three sets of gluing devices 605 are started simultaneously, and a 0.5mm wide sealant is applied to the surface of the packaging board in a serpentine path (the amount of glue is adjusted by the stepper motor controlled by the PLC).

[0048] S4. Substrate adsorption and transfer: Linear module 2 403 and linear module 1 401 move in coordination to move the air pump 606 above the substrate. At this time, the air pump 606 drives the adsorption plate 607 to descend to 1 mm above the substrate. The vacuum pump 608 starts and sucks the air in the adsorption hole 610 through the air pipe 609 (the vacuum degree reaches -80 kPa), so that the substrate is firmly adsorbed on the bottom surface of the adsorption plate 607; linear module 2 403 and linear module 1 401 move in coordination to move the adsorbed substrate horizontally to the top of the packaging plate after glue coating.

[0049] S5. Precise pressing and packaging: The air pump 606 pushes the adsorption plate 607 downward at a pressure of 0.2 MPa to evenly spread the sealant between the substrate and the packaging plate (pressing time 3-5 seconds); the vacuum pump 608 releases the adsorption, and the air pump 606 lifts the adsorption plate 607 to reset it, completing a single packaging cycle.

The operating method of the multi-station OLED packaging equipment according to any one of claims 1 to 5, characterized in that: The following steps are involved: S1, substrate and packaging plate cleaning process: the conveyor belt 3 transports the substrate and packaging plate respectively, and its synchronous movement is controlled by the PLC; when the laser sensor detects that the substrate and packaging plate enter the inlet area of ​​the UV-ozone cleaning machine 501, it sends a signal to the PLC, and the PLC immediately stops the conveyor belt 3 to ensure that the materials are accurately positioned at the cleaning station; the PLC starts the dual-axis motor 512 to drive the disc 513 to rotate, and the round block 517 on the outside of the disc 513 slides in the rectangular groove 515, forcing the rectangular plate 514 to move vertically downward along the limit block 516; the rectangular plate 514 drives the sealing plate 504 to press down through the connecting round block 510, and the vertical plate 508 at the bottom of the sealing plate 504 first contacts the surface of the conveyor belt 3, and then the long plate 507 is squeezed and compressed back into the slide groove 506, and the telescopic spring 509 is compressed and deformed, so that the sealing plate 504 is completely fitted with the inlet and outlet of the UV-ozone cleaning machine 501, forming an airtight seal; the UV-ozone cleaning machine 501 is started to clean the surfaces of the substrate and packaging plate in the sealed space; S2. Post-cleaning material flow and parallel processing: After cleaning is completed, the dual-axis motor 512 reverses, and the disc 513 drives the sealing plate 504 to rise and reset, releasing the seal; the conveyor belt 3 restarts, transporting the cleaned substrate and packaging plate to the packaging area, while the subsequent materials to be cleaned are simultaneously fed into the UV-ozone cleaning machine 501, achieving continuous operation of the cleaning station; S3. Positioning and gluing the packaging plate: Linear module 1 401 drives positioning rod 402 to move along the X-axis, and linear module 2 403 drives positioning plate 1 601 to move along the Y-axis, so that the center of fixing ring 604 of gluing device 605 is aligned with the edge of the packaging plate; The three linear modules 602 push the positioning plate 603 forward, respectively, so that the nozzle of the glue coating device 605 is 5-10 mm away from the surface of the packaging board. The three glue coating devices 605 are activated simultaneously, applying a 0.5 mm wide sealant on the surface of the packaging board in a serpentine path. S4. Substrate adsorption and transfer: Linear module 2 403 and linear module 1 401 work together to move the air pump 606 above the substrate. At this time, the air pump 606 drives the adsorption plate 607 to descend to 1 mm above the substrate. The vacuum pump 608 starts and sucks the air in the adsorption hole 610 through the air pipe 609, so that the substrate is firmly adsorbed on the bottom surface of the adsorption plate 607. The linear module 2 403 and linear module 1 401 work together to move the adsorbed substrate horizontally to the top of the packaging board after the glue is applied. S5. Precise pressing and packaging: The air pump 606 pushes the adsorption plate 607 downward at a pressure of 0.2 MPa to evenly spread the sealant between the substrate and the packaging plate; the vacuum pump 608 releases the adsorption, and the air pump 606 lifts the adsorption plate 607 to reset, completing a single packaging cycle.
