Abstract

This invention relates to the field of display module packaging technology and discloses an OLED display module packaging structure, including a bonding mechanism. A placement component is fixedly installed on the inner wall of the bonding mechanism, and a driving component is installed on the inner wall of the bonding mechanism. Activating the electric telescopic rod generates a reciprocating force, pushing a roller to roll on the substrate. Through a lifting component and a pressing component, the roller descends, increasing the pressure on the substrate. After each roll, the pressure applied by the roller gradually increases. At low pressure, the roller rolls, driving large air bubbles on the substrate surface from the center to the edge. As the pressure increases, the air bubbles are pushed to migrate along the direction of roller movement to the edge of the substrate and are extracted through a vacuum environment. Finally, the pressure increases again, and the roller compacts the adhesive between the cover plate and the substrate, ensuring uniform flow of the adhesive and a tight fit between the cover plate and the substrate, effectively preventing air bubbles from remaining inside when the cover plate and substrate are under pressure.

Description

Technical Field

[0001] This invention relates to the field of display module packaging equipment technology, specifically to an OLED display module packaging structure. Background Technology

[0002] OLED, or Organic Light Emitting Diode, also known as Organic Electroluminescent Display, refers to the phenomenon where organic semiconductor materials and light-emitting materials emit light through carrier injection and recombination under the drive of an electric field. The light-emitting principle of OLED is to use ITO pixel electrodes and metal electrodes as the anode and cathode of the device, respectively. Under a certain voltage drive, electrons and holes are injected from the cathode and anode into the electron and hole transport layers, respectively. Electrons and holes migrate through the electron and hole transport layers to the light-emitting layer, where they meet to form excitons and excite the light-emitting molecules. The latter emit visible light through radiative relaxation.

[0003] OLED display modules are made up of multiple layers of materials and precision components. When the cover plate is bonded to the substrate, a vacuum is often required to ensure that the cover plate and the substrate are tightly bonded. By directly squeezing the entire cover plate, the adhesive on the substrate will flow under pressure. During the adhesive flow process, air bubbles may be generated, which will affect the optical performance of the OLED display module. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an OLED display module packaging structure, including a bonding mechanism, a placement component fixedly installed on the inner wall of the bonding mechanism, a driving component installed on the inner wall of the bonding mechanism, and the placement component being used to place a substrate.

[0005] A rolling mechanism is installed inside the bonding mechanism and is slidably disposed inside the bonding mechanism for rolling on the substrate surface; and a pressure boosting mechanism is located inside the bonding mechanism for increasing the pressure of the rolling mechanism on both sides of the substrate.

[0006] The bonding mechanism places the substrate on the placement assembly, rolls the substrate surface to eliminate air bubbles, and then increases the pressure on both sides of the substrate as the rolling mechanism rolls, so that the cover plate and the substrate are tightly bonded. This effectively prevents air bubbles from remaining inside the cover plate and the substrate when they are under pressure, which would affect the optical performance of the OLED display module.

[0007] Preferably, the bonding mechanism has a vacuum frame inside, and the bonding mechanism includes:

[0008] The component is placed in a sliding manner with its inner wall sliding against the outer wall of the vacuum frame for placing the substrate.

[0009] The driving component is fixedly installed at its bottom and at the top of the vacuum frame, and is used to drive the vacuum frame to fit against the placement component;

[0010] The process involves placing the substrate on the placement assembly, moving the substrate to the bottom of the vacuum frame using a drive assembly, and then lowering the vacuum frame using the drive assembly to fit it against the placement assembly.

[0011] Preferably, the rolling mechanism includes:

[0012] The pushing component is slidably disposed on the inner wall of the vacuum frame via a slider, and is used to roll on the substrate surface;

[0013] The sliding component includes a sliding plate that is slidably connected to the inner wall of the vacuum frame, and a connecting pipe is connected through the inner wall of the vacuum frame.

[0014] The lifting assembly is fixedly installed on the inner wall of the vacuum frame by fasteners and is used to control the pressure of the pushing assembly on the substrate.

[0015] The fastener includes a connecting plate that is fixedly connected to the inner wall of the vacuum frame, and a spring push rod that is slidably connected to the inner wall of the connecting plate;

[0016] The extrusion assembly is fixedly mounted on the top of the vacuum frame by a support member and is used to control the multiple extrusions of the lifting assembly.

[0017] The support includes a fixed sleeve 2 that is fixedly connected to the top of the vacuum frame, and an oil supply pipe is connected through the bottom of the fixed sleeve 2.

[0018] The reset component is fixedly installed on the inner wall of the placement component via a connector and is used to control the return of the lifting component to its original position.

[0019] The connector includes a fixing rod located at the top of the vacuum frame, and a blocking rod is provided at the top of the vacuum frame;

[0020] In this process, the pushing component rolls on the substrate surface. After the pushing component rolls back and forth once, the lifting component squeezes the pushing component, increasing the pressure of the pushing component on the substrate. The squeezing component then increases the squeezing pressure of the pushing component multiple times. At low pressure, the pushing component rolls, driving large air bubbles on the substrate surface from the center to the edge. As the pressure increases, the air bubbles migrate along the direction of movement of the pushing component to the edge of the substrate and are then extracted through a vacuum environment. Finally, the pressure increases again, and the pushing component compacts the adhesive between the cover plate and the substrate, ensuring that the adhesive flows evenly and that the cover plate and the substrate are tightly bonded.

[0021] Preferably, the booster mechanism includes:

[0022] The pressing component is fixedly mounted at the bottom of the sliding plate by a pushing component, which is used to increase the pressure on the substrate on both sides of the pushing component;

[0023] The pusher includes two concave and convex plates fixedly connected to the bottom of the sliding plate, and a spring ball rod is slidably connected to the side wall of each of the two concave and convex plates.

[0024] Translation component, which is fixedly mounted on the bottom of the sliding plate by an extrusion member, is used to roll obliquely on the surface of the substrate;

[0025] The extrusion component includes two concave and convex plates fixedly connected to the bottom of the sliding plate, and two spring return rods are slidably connected to the bottom of each of the two concave and convex plates.

[0026] Specifically, by pressing the push component, the squeezing force on both sides of the substrate is intermittently increased when the push component rolls. When the pressure increases, the adhesive is forced to flow back towards the center of the substrate, which counteracts the tendency of the adhesive to flow to both sides of the substrate when squeezed. This effectively prevents the adhesive from overflowing from both sides of the substrate when it is under pressure. Then, by translating the component, the push component rolls obliquely towards the push component, flattening the adhesive on the substrate and offsetting part of the force of the push component pushing the adhesive. This disperses the pressure area of ​​the adhesive and effectively prevents the adhesive from overflowing from the left side when the push component moves from the right side of the substrate to the left side.

[0027] Preferably, the placement component includes a housing disposed inside the fitting mechanism, a placement slide is slidably connected to the top of the housing, a threaded rod is rotatably connected to the inner wall of the housing, and the outer wall of the threaded rod is threadedly connected to the inner wall of the placement slide.

[0028] The drive assembly includes a cylinder fixedly connected to the inner wall of the housing, the bottom output end of the cylinder being fixedly connected to the top of the vacuum frame, and the outer wall of the vacuum frame being slidably connected to the inner wall of the housing.

[0029] A motor is fixedly connected to the back of the housing, and the output end of the motor is fixedly connected to the side wall of the threaded rod.

[0030] In use, the staff attaches the cover plate to the substrate, places the attached substrate on the placement slide, then places protective cotton on the surface of the substrate, starts the motor to drive the threaded rod to rotate, and moves the placement slide to the bottom of the vacuum frame. Then, the cylinder extends and pushes the vacuum frame down to fit against the placement slide.

[0031] Preferably, the pushing component includes an electric telescopic rod fixedly connected to the inner wall of the vacuum frame, a connecting rod fixedly connected to the output end of the electric telescopic rod at the side wall, and the outer wall of the connecting tube slidably connected to the inner wall of the outer shell.

[0032] A fixed frame is slidably connected to the bottom of the sliding plate. A roller is rotatably connected to the inner wall of the fixed frame. The side wall of the fixed frame is slidably connected to the side wall of the connecting rod. Four spring reset rods are fixedly connected to the top of the sliding plate. The outer walls of the four spring reset rods are slidably connected to the inner wall of the vacuum frame.

[0033] After bonding, the connecting pipe is connected to the vacuum pump. Then, the vacuum pump is started to create a vacuum between the vacuum frame and the placement slide, generating negative pressure. When the vacuum frame descends, it will also drive the sliding plate, electric telescopic rod and roller one to descend synchronously, so that roller one comes into contact with the protective cotton. Then, the electric telescopic rod is started to generate the force of extension and retraction, pushing the connecting rod, fixing frame one and roller one to move synchronously towards the connecting plate, so that roller one rolls on the surface of the protective cotton and squeezes the substrate.

[0034] Preferably, the lifting assembly includes a connecting rod rotatably connected to the side wall of the spring push rod, a fixing sleeve is fixedly connected to the top of the vacuum frame, and an annular frame is slidably connected to the inner wall of the fixing sleeve.

[0035] The bottom of the ring frame is fixedly connected to the top of the sliding plate. Hydraulic oil is provided on the inner wall of the ring frame. An inclined rod is slidably connected to the inner wall of the fixed sleeve. The bottom of the inclined rod is rotatably connected to the inner wall of the connecting rod.

[0036] During the continuous movement of the fixed frame, the fixed frame will come into contact with the spring push rod, pushing the spring push rod to move, causing the connecting rod to rotate. The connecting rod will push the inclined rod to rise, causing the inclined surface between the inclined rod and the fixed sleeve to separate, creating a gap between them. The negative pressure inside the vacuum frame will then enter the fixed sleeve through the gap.

[0037] Preferably, the extrusion assembly includes an extrusion ring slidably connected to the inner wall of the annular frame, the bottom of the extrusion ring being fixedly connected to the bottom of the fixed sleeve, and the outer wall of the oil delivery pipe being slidably connected to the inner wall of the annular frame.

[0038] A spring ball rod is slidably connected to the inner wall of the oil pipeline, a rocker is rotatably connected to the inner wall of the fixed sleeve, the outer wall of the spring ball rod is slidably connected to the inner wall of the extrusion ring, and the outer wall of the spring ball rod is slidably connected to the inner wall of the ring frame.

[0039] The reset assembly includes an air supply pipe fixedly connected to the inner wall of the ring frame, a top of a blocking rod fixedly connected to the inner wall of the housing, a top of a fixing rod fixedly connected to the inner wall of the housing, and a spring ball rod slidably connected to the outer wall of the blocking rod.

[0040] During the descent of the vacuum frame, fixed sleeves one and two will descend simultaneously. Fixed sleeve two will cause the oil supply pipe to descend, and the inclined surface of the oil supply pipe will contact the spring ball rod one, pushing the spring ball rod one down and separating it from the fixed rod. Since the spring ball rod one was previously under pressure, its rebound force will be released, blocking the oil supply pipe and preventing the flow of hydraulic oil inside the annular frame. At the same time, the blocking rod will enter the air supply pipe, preventing external gas from entering the bottom of the annular frame. Meanwhile, as the inclined rod rises... When the rocker arm rotates, the side of the rocker arm in contact with the inclined plane rises while the other side falls. The falling side pushes the spring ball rod down, separating it from the inclined plane of the oil pipe. A gap appears between them, and the annular frame descends under the influence of the negative pressure inside the fixed sleeve. Since the compression ring is stationary, the descending annular frame allows its internal hydraulic oil to enter the fixed sleeve. Because the annular frame contains hydraulic oil, and this hydraulic oil enters the fixed sleeve through the gap, it slows down the movement of the annular frame under negative pressure. The speed causes the ring frame to move slowly, driving the sliding plate downwards. This causes the spring return rod to accumulate rebound force under pressure. The downward movement of the sliding plate drives the roller to descend, increasing the pressure on the base plate. Then, the electric telescopic rod retracts, separating the fixed frame from the spring push rod. At this point, the rebound force of the spring push rod is released, causing the inclined rod to return to its original position and block the fixed sleeve again. The rebound force of the spring ball rod is also released, blocking the oil pipe and stopping the flow of hydraulic oil within the ring frame, thus halting its movement until the fixed frame pushes the spring push rod to move. This process repeats itself. After each roll of the first roller, the pressure applied by the first roller gradually increases. When the pressure is low, the first roller rolls and drives large air bubbles on the substrate surface from the center to the edge. As the pressure increases, the air bubbles are pushed to migrate to the edge of the substrate along the direction of the first roller's movement and are then removed through a vacuum environment. Finally, the pressure increases again, and the first roller compacts the adhesive between the cover plate and the substrate, making the adhesive flow evenly and ensuring a tight fit between the cover plate and the substrate. This effectively prevents air bubbles from remaining inside the cover plate and the substrate when they are under pressure, which would affect the optical performance of the OLED display module.

[0041] Preferably, the pressing assembly includes twelve arc-shaped blocks slidably connected to the inner wall of the first roller, each of the twelve arc-shaped blocks having a spring compression rod slidably connected to its inner wall, and twelve fixing rings fixedly connected to the inner wall of the first roller.

[0042] The outer walls of the two spring ball rods are slidably connected to the inner wall of the roller, the outer walls of the two spring ball rods are slidably connected to the inner wall of the fixed frame, and the inner walls of the twelve fixed rings are slidably connected to the outer walls of the twelve spring compression rods.

[0043] When the fixing frame moves, it also drives the spring ball rod to move. When the spring ball rod moves from the concave position of the concave-convex plate to the convex position, it will be squeezed and move towards the roller, pushing the spring extrusion rod and the arc block to move. At this time, when the arc block contacts the substrate, the spring on the spring extrusion rod will be squeezed, causing the arc block in contact with the substrate to apply greater extrusion force to the substrate until the spring ball rod returns to its original position. This process repeats, and the arc block will intermittently increase the extrusion force on both sides of the substrate. When the pressure increases, it will force the adhesive to flow back to the center of the substrate, counteracting the tendency of the adhesive to flow to both sides of the substrate when squeezed, effectively preventing the adhesive from overflowing from both sides of the substrate when the substrate is under pressure.

[0044] Preferably, the translation component includes two connecting blocks fixedly connected to the left and right sides of the fixed frame, and the inner walls of the four connecting blocks are slidably connected to the outer walls of the four spring return rods.

[0045] Four fixed frames are provided on the side wall of fixed frame one. The top of each of the four fixed frames two is fixedly connected to a spring rod. The outer wall of each of the four spring rods is slidably connected to the inner wall of each of the four spring return rods two.

[0046] Rollers are rotatably connected to the inner walls of the four fixed frames. Two transverse plates are provided on the side walls of the two concave and convex plates. The four transverse plates are arranged in pairs. The side walls of the two sets of transverse plates are fixedly connected to the outer walls of the two spring ball rods.

[0047] When the first fixing frame moves, it also drives the connecting block, the second spring return rod, and the second fixing frame to move synchronously. This causes the second spring return rod to move from the concave position of the second concave-convex plate to the convex position, which compresses and lowers the second spring return rod. This pushes the second roller to press against the substrate. At this time, the second roller stops descending. Simultaneously, the second spring ball rod pushes the transverse plate to move. The transverse plate pushes the second roller to roll obliquely towards the first roller. When the first roller pushes the adhesive to move, it applies a reverse thrust to offset part of the force of the first roller pushing the adhesive, disperses the force area of ​​the adhesive, and effectively prevents the first roller from moving from the right side of the substrate to the left side. When the first roller moves to the left side of the substrate, it will push some of the adhesive to overflow from the left side.

[0048] The present invention has the following beneficial effects:

[0049] (1) When using this invention, after the vacuum frame is attached to the placement slide, the electric telescopic rod is activated to generate a back-and-forth contraction force, which pushes the first roller to roll on the substrate. Through the lifting component and the pressing component, the first roller is lowered to increase the pressure on the substrate. After each roll, the pressure applied by the first roller gradually increases. When the pressure is low, the first roller rolls and drives the large-sized air bubbles on the surface of the substrate from the center area to the edge. After the pressure increases, the air bubbles are pushed to migrate to the edge of the substrate along the movement direction of the first roller and are extracted through the vacuum environment. Finally, the pressure increases again and the first roller compacts the adhesive between the cover plate and the substrate, so that the adhesive flows evenly and the cover plate and the substrate are tightly attached. This effectively prevents the presence of air bubbles inside when the cover plate and the substrate are under pressure, which would affect the optical performance of the OLED display module.

[0050] (2) In this invention, the inclined rod rises, allowing negative pressure to enter the fixed sleeve. At the same time, the inclined rod pushes the rocker to rotate, causing the spring ball rod to separate from the inclined surface of the oil pipe, allowing the ring frame to descend. As the fixed frame pushes the spring push rod to move, the two will quickly separate, the spring push rod's rebound force will be released, and the inclined rod will descend, causing the spring ball rod to block the oil pipe, thus stopping the ring frame from moving quickly. This effectively prevents the ring frame from being affected by the negative pressure inside the fixed sleeve after the inclined rod blocks the fixed sleeve. The external atmospheric pressure will push the ring frame to move slowly, causing the ring frame and connecting plate to move too much, resulting in excessive pressure on the substrate.

[0051] (3) When the fixed frame moves, the spring ball rod moves as well. When the spring ball rod moves from the concave position to the convex position of the concave-convex plate, the spring ball rod will be squeezed and move towards the roller, pushing the spring extrusion rod and the arc block to move. At this time, when the arc block contacts the substrate, the spring on the spring extrusion rod will be squeezed, so that the arc block in contact with the substrate will apply greater extrusion force to the substrate until the spring ball rod returns to its original position. This process is repeated, and the arc block will intermittently increase the extrusion force on both sides of the substrate. When the pressure increases, it will force the adhesive to flow back to the center of the substrate, offsetting the tendency of the adhesive to flow to both sides of the substrate when it is squeezed, effectively preventing the adhesive from overflowing from both sides of the substrate when the substrate is under pressure.

[0052] (4) When the fixed frame moves, the connecting block, the spring return rod 2 and the fixed frame 2 will move synchronously, so that the spring return rod 2 moves from the concave position of the concave-convex plate 2 to the convex position, so that the spring return rod 2 is squeezed down, pushing the roller 2 to squeeze the substrate. At this time, the roller 2 will stop falling. At the same time, the spring ball rod 2 will push the transverse plate to move, and the transverse plate will push the roller 2 to roll obliquely in the direction of the roller 1. When the roller 1 pushes the adhesive to move, it applies a reverse thrust to offset part of the force of the roller 1 pushing the adhesive, disperse the force area of ​​the adhesive, and effectively prevent the roller 1 from moving from the right side of the substrate to the left side. When the roller 1 moves to the left side of the substrate, it will push part of the adhesive to overflow from the left side. Attached Figure Description

[0068] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0069] Example 1, please refer to Figures 1-8 The present invention is an OLED display module packaging structure, including a bonding mechanism 1, a placement component 11 fixedly installed on the inner wall of the bonding mechanism 1, a driving component 12 installed on the inner wall of the bonding mechanism 1, and the placement component 11 being used to place a substrate.

[0070] The rolling mechanism 2 is installed inside the bonding mechanism 1 and is slidably disposed inside the bonding mechanism 1 for rolling on the substrate surface; and the pressure boosting mechanism 3 is located inside the bonding mechanism 1 for increasing the pressure of the rolling mechanism 2 on both sides of the substrate.

[0071] The bonding mechanism 1 places the substrate on the placement component 11, and the rolling mechanism 2 rolls the substrate surface to eliminate air bubbles. The pressure boosting mechanism 3 increases the pressure on both sides of the substrate when the rolling mechanism 2 rolls, so that the cover plate and the substrate are tightly bonded. This effectively prevents air bubbles from remaining inside the cover plate and the substrate when they are under pressure, which would affect the optical performance of the OLED display module.

[0072] The bonding mechanism 1 has a vacuum frame 13 inside, and the bonding mechanism 1 includes:

[0073] The placement component 11 is slidably disposed on the inner wall of the vacuum frame 13 and is used to place the substrate.

[0074] The bottom of the driving component 12 is fixedly disposed with the top of the vacuum frame 13, and is used to drive the vacuum frame 13 to fit against the placement component 11;

[0075] The substrate is placed on the placement component 11, and the substrate is moved to the bottom of the vacuum frame 13 by the driving component 12. Then, the vacuum frame 13 is lowered by the driving component 12 and put into contact with the placement component 11.

[0076] The rolling mechanism 2 includes:

[0077] Pushing component 21 is slidably disposed on the inner wall of vacuum frame 13 via a slider, and is used to roll on the substrate surface;

[0078] The sliding component includes a sliding plate 211 that is slidably connected to the inner wall of the vacuum frame 13, and a connecting pipe 212 that is connected through the inner wall of the vacuum frame 13.

[0079] Lifting component 22 is fixedly installed on the inner wall of vacuum frame 13 by fasteners and is used to control the pressure of pushing component 21 on substrate;

[0080] The fastener includes a connecting plate 221 fixedly connected to the inner wall of the vacuum frame 13, and a spring push rod 222 slidably connected to the inner wall of the connecting plate 221;

[0081] The extrusion assembly 23 is fixedly mounted on the top of the vacuum frame 13 by a support member and is used to control the lifting assembly 22 to extrude multiple times.

[0082] The support includes a fixing sleeve 231 fixedly connected to the top of the vacuum frame 13, and an oil supply pipe 233 is connected through the bottom of the fixing sleeve 231.

[0083] Reset component 24 is fixedly installed on the inner wall of placement component 11 via a connector and is used to control the return of lifting component 22 to its original position.

[0084] The connector includes a fixing rod 241 disposed on the top of the vacuum frame 13, and a blocking rod 242 disposed on the top of the vacuum frame 13;

[0085] In this process, the pushing component 21 rolls on the substrate surface. After the pushing component 21 rolls back and forth once, the lifting component 22 squeezes the pushing component 21, increasing the pressure of the pushing component 21 on the substrate. Then, the squeezing component 23 can increase the squeezing pressure of the pushing component 21 multiple times. When the pressure is low, the pushing component 21 rolls, driving large air bubbles on the substrate surface from the center area to the edge. After the pressure increases, the air bubbles migrate to the edge of the substrate along the movement direction of the pushing component 21 and are extracted through a vacuum environment. Finally, the pressure increases again, and the pushing component 21 compacts the adhesive between the cover plate and the substrate, making the adhesive flow evenly and allowing the cover plate and the substrate to adhere tightly.

[0086] The booster mechanism 3 includes:

[0087] The pressing component 31 is fixedly mounted at the bottom of the sliding plate 211 by a pushing member, and is used to increase the pressure on the substrate on both sides of the pushing component 21.

[0088] The pusher includes two concave and convex plates 311 fixedly connected to the bottom of the sliding plate 211, and spring ball rods 312 are slidably connected to the side walls of the two concave and convex plates 311.

[0089] Translation component 32 is fixedly mounted on the bottom of sliding plate 211 by an extrusion member and is used to roll obliquely on the surface of the substrate.

[0090] The extrusion component includes two concave and convex plates 321 fixedly connected to the bottom of the sliding plate 211, and two spring return rods 323 are slidably connected to the bottom of each of the two concave and convex plates 321.

[0091] Specifically, by pressing the component 31, the pushing component 21 intermittently increases the squeezing force of the pushing component 21 on both sides of the substrate when it rolls. When the pressure increases, it forces the adhesive to flow back towards the center of the substrate, offsetting the tendency of the adhesive to flow to both sides of the substrate when it is squeezed. This effectively prevents the adhesive from overflowing from both sides of the substrate when it is compressed. Then, by translating the component 32, it rolls obliquely towards the pushing component 21, flattening the adhesive on the substrate, offsetting part of the force of the pushing component 21 pushing the adhesive, and dispersing the area of ​​pressure on the adhesive. This effectively prevents the pushing component 21 from moving from the right side of the substrate to the left side, and prevents some of the adhesive from overflowing from the left side when it moves to the left side of the substrate.

[0092] Example 2, please refer to Figures 1-12The present invention is an OLED display module packaging structure. Based on Example 1, the placement component 11 includes a housing 111 disposed inside the bonding mechanism 1. The top of the housing 111 is slidably connected to a placement slide 112. A threaded rod 113 is rotatably connected to the inner wall of the housing 111. The outer wall of the threaded rod 113 is threadedly connected to the inner wall of the placement slide 112.

[0093] The drive assembly 12 includes a cylinder 121 fixedly connected to the inner wall of the housing 111. The bottom output end of the cylinder 121 is fixedly connected to the top of the vacuum frame 13, and the outer wall of the vacuum frame 13 is slidably connected to the inner wall of the housing 111.

[0094] A motor 122 is fixedly connected to the back of the housing 111, and the output end of the motor 122 is fixedly connected to the side wall of the threaded rod 113.

[0095] In use, the operator attaches the cover plate to the substrate, places the attached substrate on the placement slide 112, then places protective cotton on the surface of the substrate, starts the motor 122 to drive the threaded rod 113 to rotate, and moves the placement slide 112 to the bottom of the vacuum frame 13. Then, the cylinder 121 is activated to extend and push the vacuum frame 13 down to fit against the placement slide 112.

[0096] The pushing component 21 includes an electric telescopic rod 213 fixedly connected to the inner wall of the vacuum frame 13, a connecting rod 214 fixedly connected to the output end of the side wall of the electric telescopic rod 213, and the outer wall of the connecting pipe 212 is slidably connected to the inner wall of the outer shell 111.

[0097] The bottom of the sliding plate 211 is slidably connected to a fixed frame 215, and the inner wall of the fixed frame 215 is rotatably connected to a roller 216. The side wall of the fixed frame 215 is slidably connected to the side wall of the connecting rod 214. The top of the sliding plate 211 is fixedly connected to four spring return rods 217, and the outer walls of the four spring return rods 217 are slidably connected to the inner wall of the vacuum frame 13.

[0098] After bonding, the connecting pipe 212 is connected to the vacuum pump. Then, the vacuum pump is started to create a vacuum between the vacuum frame 13 and the placement slide 112, generating negative pressure. When the vacuum frame 13 descends, it will also drive the sliding plate 211, the electric telescopic rod 213 and the roller 216 to descend synchronously, so that the roller 216 contacts the protective cotton. Then, the electric telescopic rod 213 is started to generate a force of extension and retraction, which pushes the connecting rod 214, the fixing frame 215 and the roller 216 to move synchronously towards the connecting plate 221, so that the roller 216 rolls on the surface of the protective cotton and squeezes the substrate.

[0099] The lifting assembly 22 includes a connecting rod 223 rotatably connected to the side wall of the spring push rod 222, a fixing sleeve 224 fixedly connected to the top of the vacuum frame 13, and an annular frame 225 slidably connected to the inner wall of the fixing sleeve 224.

[0100] The bottom of the ring frame 225 is fixedly connected to the top of the sliding plate 211. Hydraulic oil is provided on the inner wall of the ring frame 225. An inclined rod 226 is slidably connected to the inner wall of the fixed sleeve 224. The bottom of the inclined rod 226 is rotatably connected to the inner wall of the connecting rod 223.

[0101] During the continuous movement of the fixed frame 215, the fixed frame 215 will come into contact with the spring push rod 222, pushing the spring push rod 222 to move, causing the connecting rod 223 to rotate. The connecting rod 223 will push the inclined rod 226 to rise, causing the inclined surface between the inclined rod 226 and the fixed sleeve 224 to separate, leaving a gap between them. The negative pressure in the vacuum frame 13 will then enter the fixed sleeve 224 through the gap.

[0102] The extrusion assembly 23 includes an extrusion ring 232 that is slidably connected to the inner wall of the annular frame 225. The bottom of the extrusion ring 232 is fixedly connected to the bottom of the fixed sleeve 224. The outer wall of the oil delivery pipe 233 is slidably connected to the inner wall of the annular frame 225.

[0103] A spring ball rod 234 is slidably connected to the inner wall of the oil pipe 233, a rocker plate 235 is rotatably connected to the inner wall of the fixed sleeve 224, the outer wall of the spring ball rod 234 is slidably connected to the inner wall of the extrusion ring 232, and the outer wall of the spring ball rod 234 is slidably connected to the inner wall of the ring frame 225.

[0104] The reset assembly 24 includes an air supply pipe 243 fixedly connected to the inner wall of the ring frame 225, a top of a blocking rod 242 fixedly connected to the inner wall of the outer casing 111, a top of a fixing rod 241 fixedly connected to the inner wall of the outer casing 111, and a spring ball rod 234 slidably connected to the outer wall of the blocking rod 242.

[0105] During the descent of the vacuum frame 13, the second fixed sleeve 231 and the first fixed sleeve 224 will also descend synchronously. The second fixed sleeve 231 will cause the oil supply pipe 233 to descend until the inclined surface of the oil supply pipe 233 contacts the first spring ball rod 234, pushing the first spring ball rod 234 to descend and separate it from the fixed rod 241. Since the first spring ball rod 234 was previously under pressure, its rebound force will be released, blocking the oil supply pipe 233 and preventing the flow of hydraulic oil in the annular frame 225. At the same time, the blocking rod 242 will enter the air supply pipe 243, preventing external gas from entering the bottom of the annular frame 225. Simultaneously, as the inclined rod 226 rises, it pushes the rocker arm 235 to rotate, causing the side of the rocker arm 235 in contact with the inclined rod 226 to rise and the other side to fall. The falling side pushes the spring ball rod 234 down, causing the spring ball rod 234 to separate from the inclined surface of the oil pipe 233, creating a gap between them. At this time, the annular frame 225 will fall under the influence of the negative pressure inside the fixed sleeve 224. Since the compression ring 232 is stationary, the falling annular frame 225 will allow its internal hydraulic oil to enter the fixed sleeve 231. Because the annular frame 225 contains hydraulic oil, and the hydraulic oil enters the fixed sleeve 231 through the gap, it will reduce... The reduced movement speed of the annular frame 225 under negative pressure causes it to move slowly, driving the sliding plate 211 to descend. This causes the spring return rod 217 to accumulate rebound force. The descent of the sliding plate 211 drives the roller 216 to descend, increasing the pressure on the substrate. Subsequently, the electric telescopic rod 213 retracts, separating the fixed frame 215 from the spring push rod 222. At this time, the rebound force of the spring push rod 222 is released, causing the inclined rod 226 to return to its original position and block the fixed sleeve 224 again. The rebound force of the spring ball rod 234 is also released, blocking the oil pipe 233, stopping the flow of hydraulic oil in the annular frame 225, and allowing the annular frame 225 to... The movement stops until the fixing bracket 215 pushes the spring push rod 222 to move. This process is repeated. After each roll of the roller 216, the pressure applied by the roller 216 gradually increases. When the pressure is low, the roller 216 rolls and drives large air bubbles on the substrate surface from the center area to the edge. After the pressure increases, the air bubbles are pushed to migrate to the edge of the substrate along the movement direction of the roller 216 and are extracted through the vacuum environment. Finally, the pressure increases again and the roller 216 compacts the adhesive between the cover plate and the substrate, so that the adhesive flows evenly and the cover plate and the substrate are tightly attached. This effectively prevents air bubbles from remaining inside the cover plate and the substrate when they are under pressure, which would affect the optical performance of the OLED display module.

[0106] The pressing assembly 31 includes twelve arc-shaped blocks 313 slidably connected to the inner wall of the roller 216, and spring compression rods 314 slidably connected to the inner wall of each of the twelve arc-shaped blocks 313. Twelve fixing rings 315 are fixedly connected to the inner wall of the roller 216.

[0107] The outer walls of the two spring ball rods 312 are slidably connected to the inner walls of the roller 216, the outer walls of the two spring ball rods 312 are slidably connected to the inner walls of the fixed frame 215, and the inner walls of the twelve fixed rings 315 are slidably connected to the outer walls of the twelve spring compression rods 314.

[0108] When the fixing frame 215 moves, it also drives the spring ball rod 312 to move. When the spring ball rod 312 moves from the concave position of the concave-convex plate 311 to the convex position, the spring ball rod 312 will be squeezed and move towards the roller 216, pushing the spring compression rod 314 and the arc block 313 to move. At this time, when the arc block 313 contacts the substrate, the spring on the spring compression rod 314 will be squeezed, so that the arc block 313 in contact with the substrate will apply greater squeezing force to the substrate until the spring ball rod 312 returns to its position. This process repeats, and the arc block 313 will intermittently increase the squeezing force on both sides of the substrate. When the pressure increases, it will force the adhesive to flow back to the center of the substrate, counteracting the tendency of the adhesive to flow to both sides of the substrate when squeezed, effectively preventing the adhesive from overflowing from both sides of the substrate when the substrate is under pressure.

[0109] The translation component 32 includes two connecting blocks 322 fixedly connected to the left and right sides of the fixed frame 215, and the inner walls of the four connecting blocks 322 are slidably connected to the outer walls of the four spring return rods 323.

[0110] Four fixed brackets 324 are provided on the side wall of the fixed bracket 215. The top of each of the four fixed brackets 324 is fixedly connected to a spring rod 326. The outer wall of each of the four spring rods 326 is slidably connected to the inner wall of each of the four spring return rods 323.

[0111] Rollers 325 are rotatably connected to the inner walls of the four fixed frames 324. Two transverse plates 327 are provided on the side walls of the two concave and convex plates 311. The four transverse plates 327 are arranged in pairs. The side walls of the two sets of transverse plates 327 are fixedly connected to the outer walls of the two spring ball rods 312.

[0112] When the fixing frame 215 moves, it also drives the connecting block 322, the spring return rod 323, and the fixing frame 324 to move synchronously. This causes the spring return rod 323 to move from the concave position of the concave-convex plate 321 to the convex position, causing the spring return rod 323 to be squeezed and descend, pushing the roller 325 to squeeze the substrate. At this time, the roller 325 will stop descending. At the same time, the spring ball rod 312 will push the transverse plate 327 to move. The transverse plate 327 will push the roller 325 to roll obliquely towards the roller 216. When the roller 216 pushes the adhesive to move, it applies a reverse thrust to offset part of the force of the roller 216 pushing the adhesive, disperse the force area of ​​the adhesive, and effectively prevent the roller 216 from moving from the right side of the substrate to the left side. When the roller 216 moves to the left side of the substrate, it will push some of the adhesive to overflow from the left side.

[0113] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0114] A specific application of this embodiment is as follows: When using this invention, the operator attaches the cover plate and the substrate together, places the attached substrate on the placement slide 112, then places protective cotton on the surface of the substrate, and then starts the motor 122 to drive the threaded rod 113 to rotate, moving the placement slide 112 to the bottom of the vacuum frame 13. Then, the cylinder 121 is activated to extend, pushing the vacuum frame 13 down to fit against the placement slide 112. The connecting pipe 212 is then connected to the vacuum pump, and the vacuum pump is started to create a vacuum between the vacuum frame 13 and the placement slide 112, generating negative pressure. When the vacuum frame 13 descends, it also drives the sliding plate 211, the electric telescopic rod 213, and the roller 216 to descend synchronously, so that the roller 216 contacts the protective cotton. Then, the pump is activated. The electric telescopic rod 213 generates a reciprocating force, pushing the connecting rod 214, the first fixing frame 215, and the first roller 216 to move synchronously towards the connecting plate 221. This causes the first roller 216 to roll on the protective cotton surface, squeezing the base plate. As the first fixing frame 215 continues to move, it comes into contact with the spring push rod 222, pushing the spring push rod 222 to move, causing the connecting rod 223 to rotate. The connecting rod 223 then pushes the inclined rod 226 upward, separating the inclined surface between the inclined rod 226 and the first fixing sleeve 224, creating a gap between them. The negative pressure inside the vacuum frame 13 then enters the first fixing sleeve 224. When the vacuum frame 13 descends, it also causes the second fixing sleeve 231 and the first fixing sleeve 224 to descend synchronously. Step 31 will cause the oil supply pipe 233 to descend, and the inclined surface of the oil supply pipe 233 will contact the spring ball rod 234, pushing the spring ball rod 234 down and separating it from the fixed rod 241. Since the spring ball rod 234 was previously under pressure, its rebound force will be released, blocking the oil supply pipe 233 and preventing the flow of hydraulic oil in the annular frame 225. At the same time, the blocking rod 242 will enter the air supply pipe 243, preventing external gas from entering the bottom of the annular frame 225. Meanwhile, when the inclined rod 226 rises, it will push the rocker 235 to rotate, causing the side of the rocker 235 in contact with the inclined rod 226 to rise and the other side to fall. The lowered side will push the spring ball rod 234 down. The spring ball joint 234 is separated from the inclined surface of the oil pipe 233, creating a gap between them. At this time, the annular frame 225 will descend under the influence of the negative pressure inside the fixed sleeve 224. Since the compression ring 232 is stationary, the descending annular frame 225 will allow its internal hydraulic oil to enter the fixed sleeve 231. Because the annular frame 225 contains hydraulic oil, and the hydraulic oil enters the fixed sleeve 231 through the gap, it will slow down the movement speed of the annular frame 225 under negative pressure, causing the annular frame 225 to move slowly. This will cause the sliding plate 211 to descend, causing the spring return rod 217 to accumulate rebound force. The descent of the sliding plate 211 will cause the roller 216 to descend, increasing the pressure on the base plate. Afterward, the electric telescopic rod 213 will retract.The fixing bracket 215 separates from the spring push rod 222. At this point, the spring push rod 222's rebound force is released, causing the inclined rod 226 to return to its original position, blocking the fixing sleeve 224 again. The spring ball rod 234's rebound force is also released, blocking the oil supply pipe 233, stopping the flow of hydraulic oil in the annular frame 225, and stopping the annular frame 225's movement until the fixing bracket 215 pushes the spring push rod 222 to move. This process repeats. Each time the roller 216 rolls, the pressure applied by the roller 216 gradually increases. At low pressure, the roller 216 rolls, driving large air bubbles on the substrate surface from the center to the edge. As the pressure increases, the air bubbles are pushed along the roller 216's movement direction to the substrate edge and extracted through a vacuum environment. Finally, the pressure increases again, and the roller 216 compacts the adhesive between the cover plate and the substrate, ensuring uniform adhesive flow and a tight fit between the cover plate and the substrate. This effectively prevents air bubbles from remaining inside the cover plate and substrate under pressure, which could affect the optical performance of the OLED display module.

[0115] Secondly, the upward movement of the inclined rod 226 allows negative pressure to enter the fixed sleeve 224. Simultaneously, the inclined rod 226 pushes the rocker 235 to rotate, causing the spring ball rod 234 to separate from the inclined surface of the oil pipe 233, allowing the annular frame 225 to descend. As the fixed frame 215 pushes the spring push rod 222 to move, the two will quickly separate, releasing the rebound force of the spring push rod 222. The inclined rod 226 will then descend, causing the spring ball rod 234 to block the oil pipe 233, thus quickly stopping the annular frame 225 from moving. This effectively prevents the annular frame 225 from being affected by the negative pressure inside the fixed sleeve 224 after the inclined rod 226 blocks the fixed sleeve 224. The external atmospheric pressure would then push the annular frame 225 to move slowly, causing the annular frame 225 and the connecting plate 221 to move too much, resulting in excessive pressure on the substrate.

[0116] Secondly, when the fixing frame 215 moves, it also drives the spring ball rod 312 to move. When the spring ball rod 312 moves from the concave position of the concave-convex plate 311 to the convex position, the spring ball rod 312 will be compressed, accumulating rebound force and moving towards the roller 216. The spring ball rod 312 will contact the spring compression rod 314, pushing the spring compression rod 314 and the arc block 313 to move. At this time, when the arc block 313 contacts the substrate, the spring on the spring compression rod 314 will be compressed, causing the arc block 313 in contact with the substrate to press against the substrate. When the plate is subjected to greater compressive force, when the spring ball rod 312 contacts the concave position of the concave-convex plate 311 again, the rebound force of the spring ball rod 312 will be released, causing it to return to its original position. The arc block 313 will also return to its original position until the spring ball rod 312 contacts the convex position of the concave-convex plate 311 again. This process is repeated, and the arc block 313 will intermittently increase the compressive force on both sides of the substrate. When the pressure increases, it will force the adhesive to flow back to the center of the substrate, counteracting the tendency of the adhesive to flow to both sides of the substrate when it is compressed, effectively preventing the adhesive from overflowing from both sides of the substrate when the substrate is compressed.

[0117] Secondly, when the fixing frame 215 moves, it also drives the connecting block 322, the spring return rod 323, and the fixing frame 324 to move synchronously. This causes the spring return rod 323 to move from the recessed position of the concave-convex plate 321 to the convex position, resulting in the spring return rod 323 being compressed and descending, accumulating rebound force, and pushing the fixing frame 324 and the roller 325 to descend. This allows the roller 325 to press against the protective cotton on the surface of the substrate, and the spring return rod 323 will then fully contact the convex position of the concave-convex plate 321. The roller 325 will then stop descending. At this time, the spring ball rod 312 is still in the process of moving from the recessed position of the concave-convex plate 311 to the convex position. Therefore, the spring ball rod 312 will drive the transverse plate 327 to contact the fixing frame 324, pushing the fixing frame 324 to move and compressing the spring rod 326. This allows the spring rod 326 to accumulate rebound force, causing the second roller 325 to roll obliquely on the substrate towards the first roller 216 until the second spring return rod 323 contacts the recessed position of the second concave-convex plate 321 again, releasing the rebound force of the second spring return rod 323. This allows the second spring return rod 323, the second roller 325, and the spring rod 326 to return to their original positions until the second spring return rod 323 contacts the recessed position of the second concave-convex plate 321 again. This process repeats, causing the second roller 325 to intermittently roll obliquely on the substrate. When the first roller 216 pushes the adhesive to move, it applies a reverse thrust, offsetting part of the force of the first roller 216 pushing the adhesive, dispersing the force area of ​​the adhesive, and effectively preventing the first roller 216 from moving from the right side of the substrate to the left side. When the first roller 216 moves to the left side of the substrate, it will push some adhesive to overflow from the left side.

[0118] When the substrate is bonded, the retracting cylinder 121 raises the vacuum frame 13 and returns it to its original position. During the return process, the fixing rod 241 contacts the spring ball rod 234 again, pushing the spring ball rod 234 down and separating it from the inclined surface of the oil pipe 233. At the same time, the blocking rod 242 also separates from the gas pipe 243, and the outside gas enters the bottom of the ring frame 225 through the gas pipe 243, breaking the bottom vacuum. At this time, the spring return rod 217 releases its elastic force, allowing the sliding plate 211 to return to its original position.
