Description

Technical Field

[0001] The present invention relates to the technical field of display module packaging equipment, and particularly to an OLED display module packaging structure. Background Art

[0002] OLED, that is, organic light-emitting diode, also known as organic electroluminescent display, refers to the phenomenon that organic semiconductor materials and luminescent materials emit light under the drive of an electric field through carrier injection and recombination. The principle of OLED light emission is that ITO pixel electrodes and metal electrodes are used as the anode and cathode of the device respectively. Under the drive of a certain voltage, electrons and holes are injected from the cathode and anode into the electron and hole transport layers respectively. The electrons and holes migrate through the electron and hole transport layers to the light-emitting layer respectively, meet in the light-emitting layer, form excitons and excite the luminescent molecules, and the latter emits visible light through radiative relaxation.

[0003] Among them, the OLED display module is stacked by multiple layers of materials and precision components. When the cover plate and the substrate are bonded, it is often necessary to use vacuum to make the cover plate and the substrate fit tightly. By directly pressing the entire cover plate, when the cover plate is pressed, the glue applied on the substrate will be pressed and flow. During the flow process of the glue, bubbles may be generated, and the bubbles 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 is fixedly installed at the inner wall of the bonding mechanism, and a driving component is installed at the inner wall of the bonding mechanism. The placement component is used for placing the substrate; A rolling mechanism is installed inside the bonding mechanism. The rolling mechanism is slidably arranged inside the bonding mechanism and is used for rolling on the surface of the substrate; and a pressurizing mechanism is located inside the bonding mechanism and is used for increasing the pressure of the rolling mechanism on both sides of the substrate; Among them, the bonding mechanism places the substrate on the placement component, eliminates bubbles by rolling the rolling mechanism on the surface of the substrate, and then increases the pressure of the rolling mechanism on both sides of the substrate when rolling through the pressurizing mechanism, so that the cover plate and the substrate fit tightly, effectively preventing bubbles from remaining inside when the cover plate and the substrate are pressed, which affects the optical performance of the OLED display module.

[0005] Preferably, a vacuum frame is arranged inside the bonding mechanism. The bonding mechanism includes: A placement component, the inner wall of which is slidably arranged with the outer wall of the vacuum frame and is used for placing the substrate; A driving component, the bottom of which is fixedly arranged with the top of the vacuum frame and is used for driving the vacuum frame to fit with the placement component; Among them, the substrate is placed on the placement component, and the substrate is moved to the bottom of the vacuum frame through the driving component, and then the vacuum frame is lowered through the driving component to fit with the placement component.

[0006] Preferably, the rolling mechanism includes: A pushing component, which is slidably arranged on the inner wall of the vacuum frame through a sliding part and is used for rolling on the surface of the substrate; The sliding part includes a sliding plate slidably connected to the inner wall of the vacuum frame, and a communicating pipe is connected through the inner wall of the vacuum frame; A jacking component, which is fixedly arranged on the inner wall of the vacuum frame through a fixing part and is used to control the pressure of the pushing component on the substrate; The fixing part includes a connecting plate fixedly connected to the inner wall of the vacuum frame, and a spring push rod is slidably connected to the inner wall of the connecting plate; An extrusion component, which is fixedly arranged on the top of the vacuum frame through a support part and is used to control the extrusion of the jacking component multiple times; The support part includes a second fixing sleeve fixedly connected to the top of the vacuum frame, and an oil delivery pipe is connected through the bottom of the second fixing sleeve; A reset component, which is fixedly arranged on the inner wall of the placement component through a connecting part and is used to control the return of the jacking component; The connecting part includes a fixing rod arranged on the top of the vacuum frame, and a blocking rod is arranged on the top of the vacuum frame; Among them, by rolling the pushing component on the surface of the substrate, after the pushing component rolls back and forth once, the jacking component will squeeze the pushing component, so that the pressure of the pushing component on the substrate is increased. Then, through the extrusion component, the pushing component can increase the extrusion force multiple times. When the pressure is low, the pushing component rolls, driving the large-size bubbles on the surface of the substrate from the central area to the edge. After the pressure increases, the bubbles are pushed along the movement direction of the pushing component to the edge of the substrate and are evacuated through the vacuum environment. Finally, when the pressure rises again, the pushing component compacts the glue between the cover plate and the substrate, making the glue flow evenly and enabling the cover plate and the substrate to fit tightly.

[0007] Preferably, the pressure boosting mechanism includes: A pressing component, which is fixedly arranged at the bottom of the sliding plate through a pushing part and is used to increase the pressure on both sides of the pushing component on the substrate; The pushing part includes two first concave-convex plates fixedly connected to the bottom of the sliding plate, and two spring ball rods II are slidably connected to the side walls of the two first concave-convex plates; A translation component, which is fixedly arranged at the bottom of the sliding plate through an extrusion part and is used to roll obliquely on the surface of the substrate; The extrusion part includes two second concave-convex plates fixedly connected to the bottom of the sliding plate, and two spring return rods II are slidably connected to the bottoms of the two second concave-convex plates; Among them, when the pushing component is made to roll by the pressing component, the extrusion force of the pushing component on both sides of the substrate is intermittently increased. When the pressure rises, it will force the glue to flow back to the center of the substrate, offsetting the tendency of the glue to flow to both sides of the substrate when being extruded, effectively preventing the glue from overflowing from both sides of the substrate when the substrate is pressed. Then, through the translation component, it obliquely rolls towards the pushing component to level the glue on the substrate, offsetting part of the force of the pushing component to push the glue, dispersing the stress area of the glue, and effectively preventing part of the glue from overflowing from the left side when the pushing component moves from the right side to the left side of the substrate when the pushing component moves to the left side of the substrate.

[0008] Preferably, the placing component includes a housing arranged inside the fitting mechanism. A placing 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 placing slide. The driving component includes a cylinder fixedly connected to the inner wall of the housing. The bottom output end of the cylinder is fixedly connected to the top of the vacuum frame, and the outer wall of the vacuum frame is slidably connected to the inner wall of the housing. A motor is fixedly connected to the back of the housing, and the output end on the side wall of the motor is fixedly connected to the side wall of the threaded rod. Among them, during use, the staff fits the cover plate and the substrate together, places the fitted substrate on the placing slide, then places the protective cotton on the surface of the substrate, and then starts the motor to drive the threaded rod to rotate, transporting the placing slide to the bottom of the vacuum frame, and then starts the cylinder to extend, pushing the vacuum frame down to fit with the placing slide.

[0009] Preferably, the pushing component includes an electric telescopic rod fixedly connected to the inner wall of the vacuum frame. A connecting rod is fixedly connected to the output end on the side wall of the electric telescopic rod, and the outer wall of the connecting pipe is slidably connected to the inner wall of the housing. A fixing frame one is slidably connected to the bottom of the sliding plate. A roller one is rotatably connected to the inner wall of the fixing frame one. The side wall of the fixing frame one is slidably connected to the side wall of the connecting rod. Four spring return rods one are fixedly connected to the top of the sliding plate, and the outer walls of the four spring return rods one are all slidably connected to the inner wall of the vacuum frame. Among them, after fitting, connect the connecting pipe to the vacuum pump. Then, start the vacuum pump to form a vacuum and generate negative pressure between the vacuum frame and the placing slide. When the vacuum frame descends, it will also drive the sliding plate, the electric telescopic rod and the roller one to descend synchronously, making the roller one contact the protective cotton. Then start the electric telescopic rod to generate a reciprocating telescopic force, pushing the connecting rod, the fixing frame one and the roller one to move synchronously towards the connecting plate direction, making the roller one roll on the surface of the protective cotton to press the substrate.

[0010] Preferably, the jacking component includes a connecting rod rotatably connected to the side wall of the spring push rod. A fixing sleeve one 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 one. The bottom of the annular frame is fixedly connected to the top of the sliding plate. Hydraulic oil is provided at the inner wall of the annular frame. A bevel rod is slidably connected to the inner wall of the first fixed sleeve, and the bottom of the bevel rod is rotatably connected to the inner wall of the connecting rod. Among them, during the continuous movement of the first fixed frame, the first fixed frame will contact the spring push rod, push the spring push rod to move, cause the connecting rod to rotate, the connecting rod will push the bevel rod to rise, separate the bevel between the bevel rod and the first fixed sleeve, and let a gap leak out between the two. The negative pressure in the vacuum frame will enter the first fixed sleeve through the gap.

[0011] Preferably, the extrusion assembly includes an extrusion ring slidably connected to the inner wall of the annular frame. The bottom of the extrusion ring is fixedly connected to the bottom of the first fixed sleeve, and the outer wall of the oil delivery pipe is slidably connected to the inner wall of the annular frame. A spring ball rod one is slidably connected to the inner wall of the oil delivery pipe. A rocker is rotatably connected to the inner wall of the first fixed sleeve. The outer wall of the spring ball rod one is slidably connected to the inner wall of the extrusion ring, and the outer wall of the spring ball rod one is slidably connected to the inner wall of the annular frame. The reset assembly includes an air delivery pipe fixedly connected to the inner wall of the annular frame. The top of the blocking rod is fixedly connected to the inner wall of the housing, the top of the fixed rod is fixedly connected to the inner wall of the housing, and the inner wall of the spring ball rod one is slidably connected to the outer wall of the blocking rod. Among them, when the vacuum frame descends, it will also drive the second fixed sleeve and the first fixed sleeve to descend synchronously. The second fixed sleeve will drive the oil pipeline to descend. The inclined surface of the oil pipeline will contact the first spring ball rod, pushing the first spring ball rod to descend, causing the first spring ball rod to separate from the fixed rod. Since the first spring ball rod was in a compressed state before, at this time, the resilience of the first spring ball rod will be released, blocking the oil pipeline and preventing the hydraulic oil in the annular frame from flowing. At the same time, the blocking rod will enter the gas pipeline, preventing external gas from entering the bottom of the annular frame. At the same time, when the inclined surface rod ascends, it will push the seesaw to rotate, causing the side of the seesaw in contact with the inclined surface rod to rise and the other side to descend. The descending side will push the first spring ball rod to descend, causing the first spring ball rod to separate from the inclined surface of the oil pipeline, and a gap will leak out between the two. At this time, the annular frame will descend under the influence of the negative pressure in the first fixed sleeve. Since the extrusion ring is stationary and the annular frame descends, the hydraulic oil inside it will enter the second fixed sleeve. Since there is hydraulic oil in the annular frame and the hydraulic oil enters the second fixed sleeve through the gap, the moving speed of the annular frame when subjected to negative pressure will be slowed down, causing the annular frame to move slowly, driving the sliding plate to descend, causing the first spring return rod to be compressed and accumulate resilience. The descending sliding plate will drive the first roller to descend, increasing the extrusion pressure on the substrate. After that, the electric telescopic rod will retract, causing the first fixed frame to separate from the spring push rod. At this time, the resilience of the spring push rod will be released, causing the inclined surface rod to return to its position and blocking the first fixed sleeve again. The resilience of the first spring ball rod will also be released, blocking the oil pipeline and stopping the flow of hydraulic oil in the annular frame, causing the annular frame to stop moving until the first fixed frame pushes the spring push rod to move. This process repeats. 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, driving the large-sized bubbles on the surface of the substrate from the central area to the edge. After the pressure increases, it pushes the bubbles to migrate along the movement direction of the first roller to the edge of the substrate and be evacuated through the vacuum environment. Finally, when the pressure increases again, the first roller compresses the glue between the cover plate and the substrate, causing the glue to flow evenly and making the cover plate and the substrate fit tightly, effectively preventing bubbles from remaining inside when the cover plate and the substrate are pressed, which would affect the optical performance of the OLED display module.

[0012] Preferably, the pressing assembly includes twelve arc-shaped blocks slidably connected to the inner wall of the first roller. Spring extrusion rods are slidably connected to the inner walls of the twelve arc-shaped blocks, and twelve fixing rings are fixedly connected to the inner wall of the first roller; The outer walls of the two second spring ball rods are slidably connected to the inner wall of the first roller, and the outer walls of the two second spring ball rods are also slidably connected to the inner wall of the first fixed frame. The inner walls of the twelve fixing rings are slidably connected to the outer walls of the twelve spring extrusion rods; Among them, when the first fixing frame moves, it will also drive the second spring ball rod to move. When the second spring ball rod moves from the concave position of the first concave-convex plate to the convex position, the second spring ball rod will be squeezed and move in the direction of the first roller. Then it will push the spring extrusion rod and the arc-shaped block to move. At this time, when the arc-shaped block contacts the substrate, the spring on the spring extrusion rod will be squeezed, so that the arc-shaped block contacting the substrate will exert a greater extrusion force on the substrate until the second spring ball rod returns to its original position. In this way, the arc-shaped block will intermittently increase the extrusion force on both sides of the substrate. When the pressure rises, it will force the glue to flow back to the center of the substrate, offsetting the tendency of the glue to flow to both sides of the substrate when it is squeezed, and effectively preventing the glue from overflowing from both sides of the substrate when the substrate is under pressure.

[0013] Preferably, the translation assembly includes two connecting blocks fixedly connected to the left and right sides of the first fixing frame. The inner walls of the four connecting blocks are all slidably connected to the outer walls of the four second spring return rods. Four second fixing frames are arranged on the side wall of the first fixing frame. Springs are fixedly connected to the tops of the four second fixing frames. The outer walls of the four springs are all slidably connected to the inner walls of the four second spring return rods. Two rollers are rotatably connected to the inner walls of the four second fixing frames. Two transverse moving plates are arranged on the side walls of the two first concave-convex plates. The four transverse moving plates are divided into two groups. The side walls of the two groups of transverse moving plates are fixedly connected to the outer walls of the two second spring ball rods. Among them, when the first fixing frame moves, it will also drive the connecting blocks, the second spring return rods and the second fixing frames to move synchronously, so that the second spring return rods move from the concave position of the second concave-convex plate to the convex position, and the second spring return rods are squeezed and lowered, pushing the rollers to squeeze the substrate. At this time, the rollers will stop descending. At the same time, the second spring ball rod will push the transverse moving plate to move, and the transverse moving plate will push the rollers to roll obliquely in the direction of the first roller, exerting a reverse thrust when the first roller pushes the glue to move, offsetting part of the force of the first roller pushing the glue, and dispersing the force-bearing area of the glue, effectively preventing the first roller from moving from the right side to the left side of the substrate. When the first roller moves to the left side of the substrate, it will push some glue to overflow from the left side.

[0014] The present invention has the following beneficial effects: (1)When the present invention is in use, after the vacuum frame is fitted to the placement slide, the electric telescopic rod is activated to generate a reciprocating contraction force, which pushes the first roller to roll on the substrate. Through the lifting assembly and the extrusion assembly, the first roller descends to enhance the pressure on the substrate. 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 to drive the large-sized bubbles on the surface of the substrate from the central area to the edge. After the pressure increases, the bubbles are pushed to migrate along the moving direction of the first roller to the edge of the substrate and are evacuated through the vacuum environment. Finally, when the pressure rises again, the first roller compacts the glue applied between the cover plate and the substrate, enabling the glue to flow evenly and making the cover plate and the substrate fit tightly together, effectively preventing bubbles from remaining inside when the cover plate and the substrate are under pressure, which would affect the optical performance of the OLED display module.

[0015] (2)When the inclined plane rod of the present invention rises, negative pressure enters the first fixed sleeve. At the same time, the inclined plane rod pushes the rocker to rotate, separating the first spring ball rod from the inclined plane of the oil delivery pipe, enabling the annular frame to descend. Since the first fixed frame pushes the spring push rod to move and then they quickly separate, the resilience of the spring push rod is released, causing the inclined plane rod to descend, and the first spring ball rod blocks the oil delivery pipe, quickly stopping the movement of the annular frame. This effectively prevents the annular frame from being affected by the negative pressure in the first fixed sleeve and being slowly pushed by the external atmospheric pressure when the inclined plane rod blocks the first fixed sleeve, resulting in excessive movement amplitude of the annular frame and the connecting plate and excessive extrusion force applied to the substrate.

[0016] (3)When the first fixed frame moves in the present invention, it also drives the second spring ball rod to move. When the second spring ball rod moves from the concave position to the convex position of the first concave-convex plate, the second spring ball rod is squeezed and moves towards the first roller, pushing the spring extrusion rod and the arc-shaped block to move. At this time, when the arc-shaped block contacts the substrate, the spring on the spring extrusion rod is squeezed, causing the arc-shaped block in contact with the substrate to apply a greater extrusion force to the substrate until the second spring ball rod returns to its original position. This process is repeated, and the arc-shaped block intermittently enhances the extrusion force on both sides of the substrate. When the pressure increases, it forces the glue to flow back to the center of the substrate, counteracting the tendency of the glue to flow to both sides of the substrate when it is squeezed, effectively preventing the glue from overflowing from both sides of the substrate when the substrate is under pressure.

[0017] (4)When the first fixing frame of the present invention moves, it will also drive the connecting block, the second spring reset rod and the second fixing frame to move synchronously, so that the second spring reset rod moves from the concave position of the second concave-convex plate towards the convex position, causing the second spring reset rod to be squeezed and descend, pushing the second roller to squeeze the substrate. At this time, the second roller will stop descending. At the same time, the second spring ball rod will push the transverse plate to move, and the transverse plate will push the second roller to roll obliquely in the direction of the first roller. When the first roller moves to apply glue, a reverse thrust is applied to offset part of the force of the first roller to push the glue, dispersing the force-bearing area of the glue application, effectively preventing the first roller from moving from the right side to the left side of the substrate. When the first roller moves to the left side of the substrate, it will push part of the glue to overflow from the left side. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0022] For example, see Figures 1 - 8 The present invention is an OLED display module packaging structure, comprising a laminating mechanism 1, a placement component 11 is fixedly installed on the inner wall of the laminating mechanism 1, a driving component 12 is installed on the inner wall of the laminating mechanism 1, and the placement component 11 is used to place a substrate; A rolling mechanism 2, which is installed inside the laminating mechanism 1 and is slidably arranged inside the laminating mechanism 1 and is used to roll on the surface of the substrate; and a pressurizing mechanism 3, which is located inside the laminating mechanism 1 and is used to increase the pressure of the rolling mechanism 2 on both sides of the substrate; Among them, the bonding mechanism 1 places the substrate on the placement component 11, eliminates bubbles by rolling on the surface of the substrate through the rolling mechanism 2, and then increases the pressure on both sides of the substrate when the rolling mechanism 2 rolls through the booster mechanism 3, so that the cover plate and the substrate are tightly fitted, effectively preventing the cover plate and the substrate from being pressurized. The residual bubbles inside affect the optical performance of the OLED display module.

[0023] Inside the laminating mechanism 1, there is a vacuum frame 13.

After the pushing component 21 rolls back and forth once, the jacking component 22 will squeeze the pushing component 21, so that the pressure of the pushing component 21 on the substrate is increased. Then, through the extrusion component 23, the pushing component 21 can increase the extrusion force multiple times. When the pressure is low, the pushing component 21 rolls, driving the large-size bubbles on the surface of the substrate from the central area to the edge. After the pressure increases, the bubbles are pushed along the movement direction of the pushing component 21 to the edge of the substrate and are evacuated through the vacuum environment. Finally, when the pressure rises again, the pushing component 21 compacts the glue between the cover plate and the substrate, making the glue flow evenly and making the cover plate and the substrate fit tightly.

When the pressure rises, it will force the glue to flow back to the center of the substrate, offsetting the tendency of the glue to flow to both sides of the substrate when being extruded, effectively preventing the glue from overflowing from both sides of the substrate when the substrate is pressed. Then, through the translation component 32, it rolls obliquely towards the pushing component 21 to push flat the glue on the substrate, offsetting part of the force of the pushing component 21 to push the glue, dispersing the force-bearing area of the glue, and effectively preventing the pushing component 21 from moving from the right side to the left side of the substrate. When the pushing component 21 moves to the left side of the substrate, it will push part of the glue to overflow from the left side.

The outer walls of the four first spring return rods 217 are all slidably connected to the inner wall of the vacuum frame 13; Among them, after fitting, connect the communicating pipe 212 to the vacuum pump. Then, start the vacuum pump to form 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 first roller 216 to descend synchronously, so that the first roller 216 contacts the protective cotton. Then, start the electric telescopic rod 213 to generate a reciprocating telescopic force, pushing the connecting rod 214, the first fixing frame 215 and the first roller 216 to move synchronously towards the connecting plate 221, so that the first roller 216 rolls on the surface of the protective cotton, squeezing the substrate.

[0028] The jacking component 22 includes a connecting rod 223 rotatably connected to the side wall of the spring push rod 222. The top of the vacuum frame 13 is fixedly connected with a first fixing sleeve 224. The inner wall of the first fixing sleeve 224 is slidably connected to an annular frame 225; The bottom of the annular frame 225 is fixedly connected to the top of the sliding plate 211. There is hydraulic oil inside the inner wall of the annular frame 225. The inner wall of the first fixing sleeve 224 is slidably connected to an inclined plane rod 226. The bottom of the inclined plane rod 226 is rotatably connected to the inner wall of the connecting rod 223; Among them, during the continuous movement of the first fixing frame 215, the first fixing frame 215 will contact 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 plane rod 226 to rise, separating the inclined plane between the inclined plane rod 226 and the first fixing sleeve 224, leaving a gap between the two. The negative pressure inside the vacuum frame 13 will then enter the first fixing sleeve 224 through the gap.

[0029] The extrusion component 23 includes an extrusion ring 232 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 first fixing sleeve 224. The outer wall of the oil delivery pipe 233 is slidably connected to the inner wall of the annular frame 225; A spring ball rod 234 is slidably connected to the inner wall of the oil pipeline 233, a seesaw 235 is rotatably connected to the inner wall of the first fixing 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 annular frame 225; The reset assembly 24 includes a gas pipeline 243 fixedly connected to the inner wall of the annular frame 225, the top of the blocking rod 242 is fixedly connected to the inner wall of the housing 111, the top of the fixed rod 241 is fixedly connected to the inner wall of the housing 111, and the inner wall of the spring ball rod 234 is slidably connected to the outer wall of the blocking rod 242; Among them, when the vacuum frame 13 descends, it will also drive the second fixed sleeve 231 and the first fixed sleeve 224 to descend synchronously. The second fixed sleeve 231 will drive the oil pipeline 233 to descend until the inclined surface of the oil pipeline 233 contacts the first spring ball rod 234, pushing the first spring ball rod 234 to descend, so that the first spring ball rod 234 separates from the fixed rod 241. Since the first spring ball rod 234 was in a compressed state before, at this time, the resilience of the first spring ball rod 234 will be released, blocking the oil pipeline 233 and preventing the flow of hydraulic oil in the annular frame 225. At the same time, the blocking rod 242 will enter the gas pipeline 243 to prevent external gas from entering the bottom of the annular frame 225. At the same time, when the inclined surface rod 226 rises, it will push the seesaw 235 to rotate, causing the side of the seesaw 235 in contact with the inclined surface rod 226 to rise and the other side to lower. The lowered side will push the first spring ball rod 234 to descend, separating the first spring ball rod 234 from the inclined surface of the oil pipeline 233, and a gap will leak out between the two. At this time, the annular frame 225 will be affected by the negative pressure in the first fixed sleeve 224 and descend. Since the extrusion ring 232 is stationary and the annular frame 225 descends, the hydraulic oil inside itself will enter the second fixed sleeve 231. Since there is hydraulic oil in the annular frame 225 and the hydraulic oil enters the second fixed sleeve 231 through the gap, the moving speed of the annular frame 225 when affected by negative pressure will be slowed down, causing the annular frame 225 to move slowly, driving the sliding plate 211 to descend, compressing the first spring return rod 217 to accumulate resilience. The descent of the sliding plate 211 will drive the first roller 216 to descend, increasing the extrusion force on the substrate. After that, the electric telescopic rod 213 will retract, separating the first fixed frame 215 from the spring push rod 222. At this time, the resilience of the spring push rod 222 will be released, causing the inclined surface rod 226 to return to its original position and blocking the first fixed sleeve 224 again. The resilience of the first spring ball rod 234 will also be released, blocking the oil pipeline 233 and stopping the flow of hydraulic oil in the annular frame 225, causing the annular frame 225 to stop moving until the first fixed frame 215 pushes the spring push rod 222 to move. This process repeats. After each roll of the first roller 216, the pressure applied by the first roller 216 gradually increases. At low pressure, the first roller 216 rolls, driving large-sized bubbles on the surface of the substrate from the central area to the edge. After the pressure increases, the bubbles are pushed along the moving direction of the first roller 216 to the edge of the substrate and are evacuated through the vacuum environment. Finally, when the pressure rises again, the first roller 216 compacts the glue between the cover plate and the substrate, causing the glue to flow evenly and making the cover plate and the substrate fit tightly, effectively preventing bubbles from remaining inside when the cover plate and the substrate are under pressure, which would affect the optical performance of the OLED display module.

[0030] The pressing assembly 31 includes twelve arc-shaped blocks 313 slidably connected to the inner wall of the first roller 216. Spring pressing rods 314 are slidably connected to the inner walls of the twelve arc-shaped blocks 313, and twelve fixed rings 315 are fixedly connected to the inner wall of the first roller 216; The outer walls of the two spring ball rods II 312 are both slidably connected to the inner wall of the first roller 216, and the outer walls of the two spring ball rods II 312 are both slidably connected to the inner wall of the first fixing frame 215. The inner walls of the twelve fixing rings 315 are all slidably connected to the outer walls of the twelve spring extrusion rods 314. Among them, when the first fixing frame 215 moves, it will also drive the spring ball rod II 312 to move. When the spring ball rod II 312 moves from the concave position of the first concave-convex plate 311 towards the convex position, the spring ball rod II 312 will be squeezed and move towards the direction of the first roller 216, pushing the spring extrusion rod 314 and the arc-shaped block 313 to move. At this time, when the arc-shaped block 313 contacts the substrate, the spring on the spring extrusion rod 314 will be squeezed, so that the arc-shaped block 313 in contact with the substrate exerts a greater extrusion force on the substrate until the spring ball rod II 312 returns to its original position. In this way, the arc-shaped block 313 will intermittently increase the extrusion force on both sides of the substrate. When the pressure increases, it will force the glue to flow back to the center of the substrate, offsetting the tendency of the glue to flow to both sides of the substrate when being squeezed, effectively preventing the glue from overflowing from both sides of the substrate when the substrate is under pressure.

[0031] The translation assembly 32 includes two connecting blocks 322 fixedly connected to the left and right sides of the first fixing frame 215. The inner walls of the four connecting blocks 322 are all slidably connected to the outer walls of the four spring return rods II 323. Four fixing frames II 324 are provided on the side wall of the first fixing frame 215. Spring rods 326 are fixedly connected to the tops of the four fixing frames II 324. The outer walls of the four spring rods 326 are all slidably connected to the inner walls of the four spring return rods II 323. Two rollers II 325 are rotatably connected to the inner walls of the four fixing frames II 324. Two transverse moving plates 327 are provided on the side walls of the two first concave-convex plates 311. The four transverse moving plates 327 are grouped in pairs. The side walls of the two groups of transverse moving plates 327 are fixedly connected to the outer walls of the two spring ball rods II 312. Among them, when the first fixing frame 215 moves, it will also drive the connecting blocks 322, the spring return rods II 323 and the fixing frames II 324 to move synchronously, so that the spring return rods II 323 move from the concave position of the second concave-convex plate 321 towards the convex position, causing the spring return rods II 323 to be squeezed and descend, pushing the roller II 325 to squeeze the substrate. At this time, the roller II 325 will stop descending. At the same time, the spring ball rod II 312 will push the transverse moving plate 327 to move, and the transverse moving plate 327 will push the roller II 325 to roll obliquely in the direction of the first roller 216, exerting a reverse thrust when the first roller 216 pushes the glue to move, offsetting part of the force of the first roller 216 pushing the glue, dispersing the force-bearing area of the glue, and effectively preventing part of the glue from overflowing from the left side when the first roller 216 moves from the right side to the left side of the substrate.

[0032] The number of the above components is not limited, and those skilled in the relevant art can freely set it according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0033] A specific application of this embodiment is as follows: When the present invention is in use, the staff member fits the cover plate and the substrate together, places the completed substrate on the placement slide 112, then places the protective cotton on the surface of the substrate, and then starts the motor 122 to drive the threaded rod 113 to rotate, causing the conveying placement slide 112 to move to the bottom of the vacuum frame 13. Then, the cylinder 121 is started to extend, pushing the vacuum frame 13 down to fit with the placement slide 112. Then, the connecting pipe 212 is connected to the vacuum pump, and 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 reciprocating telescopic force, pushing the connecting rod 214, the fixing frame 215, and the roller 216 to move synchronously towards the connecting plate 221, causing the roller 216 to roll on the surface of the protective cotton and squeeze the substrate. As the fixing frame 215 continues to move, the fixing frame 215 will contact 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, separating the inclined surface between the inclined rod 226 and the fixing sleeve 224, creating a gap between the two. The negative pressure inside the vacuum frame 13 will then enter the fixing sleeve 224. Among them, when the vacuum frame 13 descends, it will also drive the fixing sleeve 231 and the fixing sleeve 224 to descend synchronously. The fixing sleeve 231 will drive the oil delivery pipe 233 to descend. The inclined surface of the oil delivery pipe 233 will contact the spring ball rod 234, pushing the spring ball rod 234 to descend, causing the spring ball rod 234 to separate from the fixing rod 241. Since the spring ball rod 234 was in a compressed state before, at this time, the resilience of the spring ball rod 234 will be released, blocking the flow of the hydraulic oil in the annular frame 225. At the same time, the blocking rod 242 will enter the air delivery pipe 243, blocking the entry of external gas into the bottom of the annular frame 225. At the same time, when the inclined rod 226 rises, it will push the seesaw 235 to rotate, causing the side of the seesaw 235 in contact with the inclined rod 226 to rise and the other side to descend. The descending side will push the spring ball rod 234 to descend, separating the spring ball rod 234 from the inclined surface of the oil delivery pipe 233, creating a gap between the two. At this time, the annular frame 225 will be affected by the negative pressure in the fixing sleeve 224 and descend. Since the extrusion ring 232 is stationary, when the annular frame 225 descends, the hydraulic oil inside itself will enter the fixing sleeve 231. Since there is hydraulic oil in the annular frame 225 and the hydraulic oil enters the fixing sleeve 231 through the gap, the moving speed of the annular frame 225 when affected by the negative pressure will be slowed down, causing the annular frame 225 to move slowly, driving the sliding plate 211 to descend, causing the spring return rod 217 to be compressed and accumulate resilience. The descent of the sliding plate 211 will drive the roller 216 to descend, increasing the extrusion force on the substrate. Then, the electric telescopic rod 213 will retract,Separate the fixing bracket 1 - 215 from the spring push rod 222. At this time, the resilience of the spring push rod 222 will be released, causing the inclined plane rod 226 to return to its original position, blocking the fixing sleeve 1 - 224 again. The resilience of the spring ball rod 1 - 234 will also be released, blocking the oil delivery pipe 233, stopping the flow of hydraulic oil in the annular frame 225, and causing the annular frame 225 to stop moving until the fixing bracket 1 - 215 pushes the spring push rod 222 to move. This process repeats. Each time the roller 1 - 216 rolls, the pressure exerted by the roller 1 - 216 gradually increases. When the pressure is low, the roller 1 - 216 rolls, driving large - sized bubbles on the surface of the substrate from the central area to the edge. After the pressure increases, it pushes the bubbles to migrate along the movement direction of the roller 1 - 216 to the edge of the substrate and evacuates them through the vacuum environment. Finally, when the pressure rises again, the roller 1 - 216 compacts the glue coating between the cover plate and the substrate, making the glue flow evenly and causing the cover plate and the substrate to fit tightly together, effectively preventing bubbles from remaining inside when the cover plate and the substrate are under pressure, which would affect the optical performance of the OLED display module; Secondly, as the inclined plane rod 226 rises, negative pressure enters the fixing sleeve 1 - 224. At the same time, the inclined plane rod 226 pushes the rocker 235 to rotate, separating the spring ball rod 1 - 234 from the inclined plane of the oil delivery pipe 233, allowing the annular frame 225 to descend. Since the fixing bracket 1 - 215 and the spring push rod 222 will separate quickly after the fixing bracket 1 - 215 pushes the spring push rod 222 to move, the resilience of the spring push rod 222 will be released, and the inclined plane rod 226 will descend, causing the spring ball rod 1 - 234 to block the oil delivery pipe 233 and quickly stopping the movement of the annular frame 225. This effectively prevents the annular frame 225 from being affected by the negative pressure in the fixing sleeve 1 - 224 and the external atmospheric pressure from pushing the annular frame 225 to move slowly after the inclined plane rod 226 blocks the fixing sleeve 1 - 224, which would result in the annular frame 225 and the connecting plate 221 having too large a movement amplitude and applying too strong a squeezing force to the substrate; Secondly, when the first fixing frame 215 moves, it will also drive the second spring ball rod 312 to move. When the second spring ball rod 312 moves from the concave position of the first concave-convex plate 311 towards the convex position, the second spring ball rod 312 will be squeezed, causing it to accumulate resilience and move towards the first roller 216. The second spring ball rod 312 will contact the spring extrusion rod 314 and push the spring extrusion rod 314 and the arc-shaped block 313 to move. At this time, when the arc-shaped block 313 contacts the substrate, the spring on the spring extrusion rod 314 will be squeezed, causing the arc-shaped block 313 in contact with the substrate to exert a greater extrusion force on the substrate. When the second spring ball rod 312 contacts the concave position of the first concave-convex plate 311 again, the resilience of the second spring ball rod 312 will be released, causing it to return to its original position, and the arc-shaped block 313 will also return to its original position until the second spring ball rod 312 contacts the convex position of the first concave-convex plate 311 again. In this way, the arc-shaped block 313 will intermittently increase the extrusion force on both sides of the substrate. When the pressure increases, it will force the glue to flow back towards the center of the substrate, offsetting the tendency of the glue to flow towards both sides of the substrate when it is squeezed, effectively preventing the glue from overflowing from both sides of the substrate when the substrate is under pressure; Secondly, when the first fixing frame 215 moves, it will also drive the connecting block 322, the second spring return rod 323 and the second fixing frame 324 to move synchronously, causing the second spring return rod 323 to move from the concave position of the second concave-convex plate 321 towards the convex position, causing the second spring return rod 323 to be squeezed and descend, accumulating resilience, and pushing the second fixing frame 324 and the second roller 325 to descend, causing the second roller 325 to squeeze the protective cotton on the surface of the substrate. The second spring return rod 323 will be in full contact with the convex position of the second concave-convex plate 321, and the second roller 325 will stop descending. At this time, the second spring ball rod 312 is still in the process of moving from the concave position of the first concave-convex plate 311 towards the convex position. Therefore, the second spring ball rod 312 will drive the transverse movement plate 327 to contact the second fixing frame 324, push the second fixing frame 324 to move, squeeze the spring rod 326, causing the spring rod 326 to accumulate resilience, and causing the second roller 325 to roll obliquely on the substrate towards the direction of the first roller 216 until the second spring return rod 323 contacts the concave position of the second concave-convex plate 321 again, causing the resilience of the second spring return rod 323 to be released, and causing 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 concave position of the second concave-convex plate 321 again. In this way, the second roller 325 will intermittently roll obliquely on the substrate, exerting a reverse thrust when the first roller 216 pushes the glue to move, offsetting part of the force of the first roller 216 pushing the glue, dispersing the force-bearing area of the glue, and effectively preventing the first roller 216 from moving from the right side to the left side of the substrate. When the first roller 216 moves to the left side of the substrate, it will push some of the glue to overflow from the left side; Wherein, after the substrate fitting is completed, the cylinder 121 is retracted to raise the vacuum frame 13 and return the vacuum frame 13 to its original position. During the return process, the fixing rod 241 will contact the first spring ball rod 234 again, pushing the first spring ball rod 234 downward to separate the first spring ball rod 234 from the inclined surface of the oil delivery pipe 233. At the same time, the blocking rod 242 will also be separated from the air delivery pipe 243, and the external gas will enter the bottom of the annular frame 225 through the air delivery pipe 243 to break the bottom vacuum. At this time, the resilience of the first spring return rod 217 will be released to return the sliding plate 211 to its original position.
