Description

Technical Field

[0001] This invention relates to the field of OLED displays, and more particularly to a high-efficiency packaging system for OLED display fabrication. Background Technology

[0002] OLED displays are a new type of digital product. Because of their thinness, lightness, and energy efficiency, OLEDs have been widely used in the displays of digital products and have great market potential. Currently, the application of OLEDs worldwide is focused on flat panel displays.

[0003] During the encapsulation of OLED displays, the substrate needs to be positioned and fixed to facilitate the encapsulation of LED chips onto the substrate. Existing substrate fixing devices, such as traditional four-point fixing devices, can only fix square or round substrates and cannot fix and encapsulate rectangular or irregularly shaped substrates, resulting in poor adaptability. At the same time, traditional fixing devices are prone to damaging the outer surface of the OLED display, causing damage to the OLED display. In addition, the lifespan of OLED displays is easily shortened by the influence of surrounding moisture and oxygen. During the manufacturing process of OLED displays, moisture is easily adsorbed and entered. Therefore, during the encapsulation of OLED displays, moisture absorption is required to prevent moisture from entering the OLED display. Summary of the Invention

[0004] To address the technical problems of traditional fixing devices easily damaging the outer surface of OLED displays, causing damage to the OLED displays, and the easy absorption of moisture by the OLED displays, this invention provides a high-efficiency packaging system for OLED display manufacturing.

[0005] The present invention is achieved by the following technical solution: a high-efficiency packaging system for OLED display manufacturing, comprising a packaging box body, wherein a packaging mechanism body is provided inside the packaging box body, and the packaging mechanism body includes a display screen overlapping mechanism and a display screen clamping mechanism;

[0006] An OLED display body is placed between the display splicing mechanism and the display clamping mechanism. A water vapor absorption mechanism is set above the OLED display body to absorb water vapor on the OLED display body.

[0007] As a further improvement to the above solution, the display screen mounting mechanism includes:

[0008] The system comprises: a support frame that supports the main body of the display screen mounting mechanism; a support platform mounted on top of the support frame; a sliding rail connected above the support platform; a sliding block fitted onto the upper surface of the sliding rail and sliding along it; a connecting plate mounted above the sliding block; a snap-fit ​​bracket fixedly connected to the connecting plate; and a mounting block positioned at the top of the snap-fit ​​bracket. The mounting block, a flat plate, is positioned at the top of the snap-fit ​​bracket, and the main body of the OLED display screen is mounted on the snap-fit ​​bracket.

[0009] The built-in drive unit of the display overlap mechanism controls the sliding block to slide on the sliding rail. The sliding block drives the connecting plate to adjust its position. The connecting plate then drives the connected snap-fit ​​bracket and overlap block to move synchronously. The overlap block then overlaps the bottom of the OLED display body, thus supporting the OLED display body from below and ensuring its stability. Because it is supported from below, it will not damage the OLED display body.

[0010] As a further improvement to the above solution, the display screen clamping mechanism includes:

[0011] The mounting column supports the main body of the display screen clamping mechanism; the mounting platform is connected to the top of the mounting column; the moving rod is movably connected above the mounting platform; the control motor is connected above the moving rod; the control shaft is connected to the outside of the control motor; and the clamping rod is connected to the outside of the control shaft. Two sets of clamping rods are arranged opposite each other, vertically distributed, and connected to the control shaft. The control shaft controls the vertical movement of the clamping rods for clamping operations. Both sets of clamping rods are made of flexible material to protect the clamped OLED display screen.

[0012] After the lap block supports the OLED display body, the motor drives the control shaft to work, controlling the two sets of vertically connected clamping rods to perform vertical clamping operations (this is a simple vertical clamping action, based on a basic mechanical principle, and the working process will not be elaborated here). The two sets of relatively connected clamping rods clamp and fix the OLED display body, ensuring the stability of the OLED display body. At the same time, the clamping rods are made of flexible material, so they will not cause damage to the OLED display body, avoiding the problem that traditional fixing devices are prone to damaging the outer surface of the OLED display.

[0013] As a further improvement to the above scheme, the water vapor absorption mechanism includes:

[0014] The system includes: a receiving plate connected to the top inner wall of the packaging box body; a connecting pipe that passes through the receiving plate and the top inner interior of the packaging box body; a hydraulic valve connected to the bottom of the connecting pipe; a receiving column connected to the bottom of the receiving plate; a snap-fit ​​plate connected to the bottom of the receiving column; and a suction head connected to the bottom of the hydraulic valve, which overlaps the top of the OLED display body.

[0015] After the OLED display body is clamped and fixed, the hydraulic valve then operates, controlling the suction head to generate a suction airflow. The suction head then adsorbs the water vapor suspended or adsorbed on the OLED display body. The water vapor then passes through the suction head and connecting pipes and is discharged, preventing water vapor from entering the OLED display body during the encapsulation process and causing damage to the OLED display body.

[0016] As a further improvement to the above solution, the display screen overlapping mechanism is provided in two opposing sets, the display screen clamping mechanism is provided in two opposing sets, and the OLED display screen body is placed between the two sets of display screen overlapping mechanisms and the display screen clamping mechanism.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The present invention uses an overlapping block to overlap the bottom of the OLED display body, thereby supporting the OLED display body from below and ensuring the stability of the OLED display body. Since it is supported from below, it will not cause damage to the OLED display body.

[0019] 2. This invention performs vertical clamping operations by controlling two sets of vertically connected clamping rods. The two sets of relatively connected clamping rods clamp and fix the OLED display body, ensuring the stability of the OLED display body. At the same time, the clamping rods are made of flexible material, so they will not cause damage to the OLED display body, avoiding the problem that traditional fixing devices are prone to damaging the outer surface of the OLED display.

[0020] 3. This invention operates through a hydraulic valve, which controls the back suction head to generate a back suction airflow. The back suction head then adsorbs water vapor suspended or adsorbed on the OLED display body. The water vapor then passes through the back suction head and the connecting pipe and is discharged, preventing water vapor from entering the OLED display body during the encapsulation process and causing damage to the OLED display body.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] Example 1:

[0033] Please combine Figures 1-8 This embodiment proposes a high-efficiency packaging system for OLED display fabrication, including a packaging box body 1, and a packaging mechanism body 2 is provided inside the packaging box body 1. The packaging mechanism body 2 includes a display overlapping mechanism 3 and a display clamping mechanism 4. The display overlapping mechanism 3 is provided in two opposing groups, and the display clamping mechanism 4 is provided in two opposing groups. The OLED display body 6 is placed between the two groups of display overlapping mechanisms 3 and display clamping mechanisms 4.

[0034] An OLED display body 6 is placed between the display overlap mechanism 3 and the display clamping mechanism 4. A water vapor absorption mechanism 5 is provided above the OLED display body 6 to absorb water vapor on the OLED display body 6.

[0035] The display screen mounting mechanism 3 includes:

[0036] Support frame 31 supports the main body of the display screen mounting mechanism 3; support platform 32 is installed on the top of support frame 31; sliding rail 33 is connected above support platform 32; sliding block 34 is sleeved on the upper surface of sliding rail 33 and slides on sliding rail 33; connecting plate 35 is installed above sliding block 34; snap-fit ​​bracket 36 is fixedly connected to connecting plate 35.

[0037] Overlapping block 37 is located at the top of the mounting bracket 36. Overlapping block 37 is a flat plate, and the OLED display body 6 overlaps on the mounting bracket 36.

[0038] Through the operation of the built-in drive unit of the display overlap mechanism 3, the sliding block 34 is controlled to slide on the sliding rail 33. The sliding block 34 drives the connecting plate 35 to adjust its position. The connecting plate 35 then drives the connected snap-fit ​​bracket 36 and overlap block 37 to move synchronously. The overlap block 37 then overlaps under the OLED display body 6, thus supporting the OLED display body 6 from below and ensuring the stability of the OLED display body 6. Since it is supported from below, it will not cause damage to the OLED display body 6.

[0039] The display screen clamping mechanism 4 includes:

[0040] Mounting post 41 supports the main body of the display screen clamping mechanism 4; mounting platform 42 is connected to the top of mounting post 41; moving rod 43 is movably connected above mounting platform 42; control motor 44 is connected above moving rod 43; control shaft 45 is connected to the outside of control motor 44; clamping rod 46 is connected to the outside of control shaft 45. Two sets of clamping rods 46 are arranged opposite each other, vertically distributed, and connected to control shaft 45. Control shaft 45 controls the clamping rods 46 to move vertically for clamping operations. Both sets of clamping rods 46 are made of flexible material to protect the clamped OLED display screen body 6.

[0041] After the overlapping block 37 supports the OLED display body 6, the operation of the control motor 44 drives the control shaft 45 to work, controlling the two sets of vertically connected clamping rods 46 to perform vertical clamping operations (this is a simple vertical clamping action, based on a simple mechanical principle, and the working process will not be elaborated here). The two sets of relatively connected clamping rods 46 thus clamp and fix the OLED display body 6, ensuring the stability of the OLED display body 6. At the same time, the clamping rods 46 are made of flexible material, so they will not cause damage to the OLED display body 6, avoiding the problem that traditional fixing devices are prone to damaging the outer surface of the OLED display.

[0042] The water vapor absorption mechanism 5 includes:

[0043] A receiving plate 51 is connected to the top of the inner wall of the packaging box body 1; a connecting pipe 52 passes through the receiving plate 51 and the top of the inner wall of the packaging box body 1; a hydraulic valve 53 is connected to the bottom of the connecting pipe 52; a receiving column 54 is connected to the bottom of the receiving plate 51; a snap-fit ​​plate 55 is connected to the bottom of the receiving column 54; and a back suction head 56 is connected to the bottom of the hydraulic valve 53 and overlaps the top of the OLED display body 6.

[0044] After the OLED display body 6 is clamped and fixed, the hydraulic valve 53 immediately starts working. The hydraulic valve 53 controls the back suction head 56 to generate back suction airflow. The back suction head 56 then adsorbs the water vapor suspended or adsorbed on the OLED display body 6. The water vapor then passes through the back suction head 56 and the connecting pipe 52 and is discharged, preventing water vapor from entering the OLED display body 6 during the encapsulation process and causing damage to the OLED display body 6.

[0045] Specific implementation steps of this invention:

[0046] In use, the built-in drive unit of the display screen overlapping mechanism 3 controls the sliding block 34 to slide on the sliding rail 33. The sliding block 34 drives the connecting plate 35 to adjust its position. The connecting plate 35 then drives the connected snap-fit ​​bracket 36 and overlapping block 37 to move synchronously. The overlapping block 37 then overlaps under the OLED display screen body 6, thus supporting the OLED display screen body 6 from below and ensuring the stability of the OLED display screen body 6. Since it is supported from below, it will not cause damage to the OLED display screen body 6.

[0047] After the overlapping block 37 supports the OLED display body 6, the operation of the control motor 44 drives the control shaft 45 to work, controlling the two sets of vertically connected clamping rods 46 to perform vertical clamping operations (this is a simple vertical clamping action, based on a simple mechanical principle, and the working process will not be elaborated here). The two sets of relatively connected clamping rods 46 thus clamp and fix the OLED display body 6, ensuring the stability of the OLED display body 6. At the same time, the clamping rods 46 are made of flexible material, so they will not cause damage to the OLED display body 6, avoiding the problem that traditional fixing devices are prone to damaging the outer surface of the OLED display.

[0048] After the OLED display body 6 is clamped and fixed, the hydraulic valve 53 immediately starts working. The hydraulic valve 53 controls the back suction head 56 to generate back suction airflow. The back suction head 56 then adsorbs the water vapor suspended or adsorbed on the OLED display body 6. The water vapor then passes through the back suction head 56 and the connecting pipe 52 and is discharged, preventing water vapor from entering the OLED display body 6 during the encapsulation process and causing damage to the OLED display body 6.

[0049] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
