Description

Technical Field

[0001] This invention belongs to the field of hot pressing of electronic displays, specifically relating to a fully automatic hot pressing device for the production of electronic displays. Background Technology

[0002] The hot-pressing device for electronic displays uses the combined action of pressure and heat to make the internal structure of the display module stick together, which determines the display yield.

[0003] Patent publication number CN120195907B relates to a hot pressing device and method for LCD screen production, including a base, a support on the base, a cylinder above the support, the output end of the cylinder passing through the upper surface of the support and connected to a connecting element, a hot pressing element below the connecting element, a heat preservation module and a heat dissipation module inside the hot pressing element, a ring-shaped blind groove on the lower surface of the hot pressing element, the heat preservation module including several springs disposed in the blind groove, a heat preservation frame fixedly connected to the lower end of the springs, a shaft on one side of the heat preservation frame, a heat preservation film wound and connected to the shaft, the movable end of the heat preservation film passing through one side of the heat preservation frame and fixedly connected to a film rod, and connecting wires tied to both ends of the film rod. This device solves the problem that current hot pressing devices cannot reasonably control the heat preservation and heat dissipation of the hot pressing plate.

[0004] In the aforementioned patent, by setting the motor to be off and the dual-axis motor to start and drive the two spools to rotate simultaneously, the connecting wire is wound up, and the connecting wire pulls the film rod to move towards the spool, causing the insulation film to unfold and lay on the hot-pressing element between the insulation frames, thereby achieving the heat insulation effect on the hot-pressing element. However, it is difficult to ensure that the display screen is aligned with the hot-pressing module in a straight position before hot-pressing, resulting in uneven stress on the surface of the display screen during the hot-pressing process. In the prior art, the position of the display screen is usually manually adjusted before the conveying mechanism transports the display screen to the hot-pressing area, which is not accurate. Moreover, the adhesive layer in the middle of the display screen is prone to overflow due to excessive stress in a certain area. If the adhesive layer melts and overflows during the hot-pressing process, it will stick to the surrounding components, making it difficult to remove the display screen. The vibration of the mechanical components during the operation of the hot-pressing process can easily cause the display screen to shake, affecting the stability of the hot-pressing process. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic hot pressing device for the production of electronic displays, so as to solve the problem of low efficiency caused by the need for manual positioning before hot pressing of displays in the prior art.

[0006] To achieve the above objectives, the present invention provides a fully automatic hot pressing device for electronic display screen production, comprising: a base and a first hydraulic rod, wherein two sets of the first hydraulic rod are symmetrically arranged on both sides of the base, and the output end of the first hydraulic rod is provided with a long push plate and a long clamping plate. After the first hydraulic rod is started, the output end drives the long push plate and the long clamping plate to move, pushing the display screen from the left and right sides to make the display screen in a flat state. The long clamping plate is provided with a short push plate and a short clamping plate on both sides. When the long clamping plate moves, it drives the short clamping plate to move, and the short clamping plate pushes the front and rear sides of the display screen to make the display screen completely enter the hot pressing area without the need for manual position adjustment, thus improving work efficiency. The surface of the base is provided with a second hydraulic rod, and the bottom sides of the second hydraulic rod are provided with hot pressing rollers. After the second hydraulic rod is started, it drives the hot pressing rollers to move downward to contact the display screen and perform hot pressing on the display screen.

[0007] In one or more embodiments of the present invention, a first buffer spring is provided between the long push plate and the long clamping plate, and a push rod is provided between the long push plate and the short push plate. When the long clamping plate moves to the point where its surface contacts the side of the display screen, the long clamping plate stops moving. The long push plate applies a pushing force to the surface of the long clamping plate by squeezing the first buffer spring, so that the long clamping plate obtains a clamping force on the display screen, and the elastic force of the first buffer spring prevents the long clamping plate from excessively squeezing the display screen. One end of the push rod is hinged to the surface of the long push plate, and the other end is hinged to the short push plate. A second buffer spring is provided between the short push plate and the short clamping plate. The long push plate pushes the push rod to deflect, and after the push rod deflects, it pushes the short push plate to move. The short push plate drives the short clamping plate to move towards the display screen. The second buffer spring prevents the short clamping plate from excessively squeezing the display screen.

[0008] In one or more embodiments of the present invention, the surface of the long clamping plate is provided with two long strips. The lower long strip is fixedly installed on the surface of the long clamping plate, while the upper long strip is slidably installed on the surface of the long clamping plate. The surface of the long push plate is provided with a stop bar. When the long push plate moves, it drives the stop bar to move. The surface of the upper long strip is provided with an inclined surface near the stop bar. After the stop bar moves, it presses the inclined surface of the upper long strip, pushing the upper long strip to move upward. The upper long strip lifts the cover plate, and the cover plate and the substrate are slightly separated while ensuring that the cover plate and the substrate are still aligned. This allows the cover plate and all parts of the adhesive layer to contact each other simultaneously during the subsequent hot pressing process, ensuring uniform adhesion.

[0009] In one or more embodiments of the present invention, a motor is fixedly installed at the output end of the second hydraulic rod, and a bracket is rotatably installed at the output end of the second hydraulic rod. The bracket meshes with the surface of the motor output end. After the motor starts, the output end rotates and pushes the bracket to rotate. The rotation of the bracket drives the hot pressing wheel to roll and hot press on the surface of the display screen. A rack is slidably installed on both sides of the bracket. The rack meshes with the output end of the second hydraulic rod. While the bracket rotates, it pushes the rack to retract. A frame is provided on the surface of the rack. The hot pressing wheel is located inside the frame. During the retraction of the rack, it drives the hot pressing wheel to gradually move closer. The hot pressing wheel hot presses the display screen from the outermost side to the center in sequence, so that the outermost adhesive layer between the cover plate and the substrate is hot-pressed and cooled in advance, and solidifies in advance. This forms a physical barrier to the inner adhesive layer, reducing the loss of the adhesive layer after hot pressing and melting. The first hydraulic rod, the second hydraulic rod, the motor, and the hot pressing wheel are connected to the control unit. The control unit adjusts the temperature and movement mode of the hot pressing wheel according to the hot pressing steps.

[0010] In one or more embodiments of the present invention, a third buffer spring is provided between the frame and the bracket. The third buffer spring prevents the hot pressure roller from excessively squeezing the surface of the display screen and damaging the display screen. A follower plate is slidably installed on the surface of the short clamp plate. The follower plate serves as the contact medium between the display screen and the short clamp plate, reducing the longitudinal friction between the short clamp plate and the display screen, so that the upper strip can smoothly lift the cover plate of the display screen.

[0011] In one or more embodiments of the present invention, the strips are parallel to each other and have gaps, so that even if the adhesive layer melts and overflows from the display screen during the hot pressing process, it is difficult for the display screen to stick to the outside, ensuring that the display screen can be easily removed after the hot pressing is completed.

[0012] In one or more embodiments of the present invention, an arc strip is fixedly installed on the surface of the long push plate, and a plurality of rotating rods are rotatably installed on the surface of the arc strip. Abutment plates are fixedly installed at both ends of the bracket. When the bracket rotates, the abutment plates rotate, and the rotating rods rotate. Baffles are provided on both sides of the rotating rods. An arc plate is sleeved at the bottom of the arc strip, and the baffles are fixedly installed on the surface of the arc plate. After the rotating rods rotate, the bottom pushes the baffles, causing the arc plate to move. A first spring is provided between the arc plate and the arc strip, and the spring force of the first spring resets the arc plate. A sliding rod is slidably installed on the surface of the long push plate, and a protruding rod is fixedly installed at the bottom of the arc plate. The protruding rod is sleeved on the surface of the sliding rod. When the arc plate moves, the protruding rod presses against the surface of the sliding rod, causing the sliding rod to move. Arc heads are provided on both sides of the sliding rod. The movement of the sliding rod causes the arc heads to move and press against the short push plate. By pressing against the short push plate, the pushing force of the second buffer spring on the short clamping plate is increased, supplementing the clamping force for the display screen, preventing the display screen from shaking during hot pressing, and ensuring the stable operation of the hot pressing process.

[0013] In one or more embodiments of the present invention, the arc head is close to the short push plate, a torsion spring is provided between the rotating rod and the arc strip, the elastic force of the torsion spring causes the rotating rod to return to its original position, and a second spring is provided between the sliding rod and the long push plate, the elastic force of the second spring causes the sliding rod to return to its original position.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (i) The display screen is positioned by the joint pushing of the long and short clamps, so that the display screen enters the hot pressing area straight without the need for manual position adjustment, thus improving work efficiency. The upper strip lifts the cover plate of the display screen during the positioning process, ensuring that the cover plate and the substrate are slightly separated while still aligned. This prevents some cover plates from sticking to the unevenly coated adhesive layer in advance, so that the cover plate and the adhesive layer are in contact at the same time during the subsequent hot pressing process, ensuring uniform bonding.

[0015] (ii) The display screen is hot-pressed from the outermost side to the center by hot-pressing rollers, so that the outermost adhesive layer between the cover plate and the substrate is hot-pressed and cooled in advance, and solidified in advance. This forms a physical barrier to the inner adhesive layer, reducing the loss of adhesive layer after hot pressing and melting. This ensures that the display screen and the adhesive layer are fully bonded. At the same time, during the hot pressing process, because there is a gap between the upper and lower strips, even if the adhesive layer melts and overflows during the hot pressing process, it will not stick to the outside, ensuring that the display screen can be easily recycled after the hot pressing is completed.

[0016] (iii) During the rotation of the bracket, the abutment plate is rotated, which pushes the rotating rod to drive the sliding rod to push back, supplementing the thrust of the short clamp plate and stabilizing the display screen. Moreover, regardless of the rotation direction of the hot pressing wheel, stress is supplemented on the surface of the display screen in the opposite direction of the hot pressing wheel's movement path, preventing the display screen from shaking during the hot pressing process and ensuring the stable progress of the hot pressing process.

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figures 1-7 As shown, one embodiment of the present invention is: a fully automatic hot pressing device for electronic display screen production, comprising: a base 1 and a first hydraulic rod 2. The first hydraulic rod 2 has two sets symmetrically arranged on both sides of the base 1. The output end of the first hydraulic rod 2 is provided with a long push plate 7 and a long clamping plate 8. After the first hydraulic rod 2 is started, the output end drives the long push plate 7 and the long clamping plate 8 to move, pushing the display screen from the left and right sides. The long clamping plate 8 is provided with a short push plate 10 and a short clamping plate 11 on both sides. When the long clamping plate 8 moves, it drives the short clamping plate 11 to move, and the short clamping plate 11 pushes the display screen to the front and rear sides so that the display screen completely enters the hot pressing area. The surface of the base 1 is provided with a second hydraulic rod 3. The bottom sides of the second hydraulic rod 3 are provided with hot pressing rollers 6. After the second hydraulic rod 3 is started, it drives the hot pressing rollers 6 to move downward to contact the display screen and perform hot pressing on the display screen.

[0021] A first buffer spring 9 is provided between the long push plate 7 and the long clamping plate 8, and a push rod 13 is provided between the long push plate 7 and the short push plate 10. When the long clamping plate 8 moves to the point where its surface contacts the side of the display screen, the long clamping plate 8 stops moving. The long push plate 7 applies a pushing force to the surface of the long clamping plate 8 by squeezing the first buffer spring 9, so that the long clamping plate 8 obtains a clamping force on the display screen. The elasticity of the first buffer spring 9 prevents the long clamping plate 8 from excessively squeezing the display screen. One end of the push rod 13 is hinged to the surface of the long push plate 7, and the other end is hinged to the short push plate 10. A second buffer spring 12 is provided between the short push plate 10 and the short clamping plate 11. The long push plate 7 pushes the push rod 13 to deflect. After the push rod 13 deflects, it pushes the short push plate 10 to move. The short push plate 10 drives the short clamping plate 11 to move towards the display screen.

[0022] The long clamp plate 8 has two long strips 14 on its surface. The lower long strip 14 is fixedly installed on the surface of the long clamp plate 8, while the upper long strip 14 is slidably installed on the surface of the long clamp plate 8. The long push plate 7 has a stop rod 15 on its surface. When the long push plate 7 moves, it drives the stop rod 15 to move. The surface of the upper long strip 14 is provided with an inclined surface near the stop rod 15. After the stop rod 15 moves, it presses the inclined surface of the upper long strip 14, pushing the upper long strip 14 to move upward, thereby lifting the cover plate.

[0023] In this embodiment, the electronic display screen needs to be adjusted in position before hot pressing to ensure that the surface of the display screen is subjected to uniform force during the hot pressing process, and that all parts inside are fully compacted, so that the display screen substrate and the cover plate are tightly bonded.

[0024] A conveyor mechanism, such as a conveyor belt, can be added to the surface of the base 1 to transport the display screen. When the display screen is transported between the two long clamping plates 8, the first hydraulic rod 2 starts to work. The output end of the first hydraulic rod 2 pushes the long push plate 7 to move. The long push plate 7 drives the long clamping plate 8 to move towards the display screen, pushing and positioning the left and right sides of the display screen to keep them flat. When the long clamping plate 8 moves to the point where its surface contacts the side of the display screen, the long clamping plate 8 stops moving. The long push plate 7 applies a pushing force to the surface of the long clamping plate 8 by squeezing the first buffer spring 9, so that the long clamping plate 8 obtains a clamping force on the display screen. Moreover, the elasticity of the first buffer spring 9 can also prevent the long clamping plate 8 from excessively squeezing the display screen. After the long clamping plate 8 contacts the side of the display screen, the long push plate 7 continues to move and gradually approaches the long clamping plate 8, pushing the push rod 13 to deflect. After the push rod 13 deflects, it pushes the short push plate 10 to move. The short push plate 10 drives the short clamping plate 11 to move towards the display screen. When the short clamping plates 11 on both sides contact the display screen, they push the display screen from both the front and rear sides, so that the display screen reaches the hot pressing area. Similarly, the elasticity of the second buffer spring 12 prevents the short clamping plate 11 from excessively squeezing the display screen and damaging it. Through the joint pushing of the long clamping plate 8 and the short clamping plate 11, the positioning of the display screen is completed, so that the display screen enters the hot pressing area straight without manual position adjustment, thus improving work efficiency. Simultaneously, as the long push plate 7 approaches the long clamping plate 8, the long push plate 7 drives the abutment rod 15 to move. After the abutment rod 15 moves, it contacts and presses the inclined surface of the upper strip 14, pushing the upper strip 14 to move upward. After the strip 14 moves, it slightly lifts the cover plate of the display screen upward and separates it from the substrate. Because the adhesive layer filling between the substrate and the cover plate may have uneven coating, the contact between different parts of the adhesive layer and the cover plate is different. Under the influence of gravity, the cover plate will contact and bond with some parts of the adhesive layer in advance. By lifting the cover plate with the upper strip 14, it is slightly separated while ensuring that the cover plate and the substrate are still aligned, so that during the subsequent hot pressing process, the cover plate and all parts of the adhesive layer contact simultaneously, ensuring uniform bonding.

[0025] Please see Figures 1-7In another embodiment of the present invention, based on the above embodiments, a motor 4 is fixedly installed at the output end of the second hydraulic rod 3, and a bracket 5 is rotatably installed at the output end of the second hydraulic rod 3. The bracket 5 meshes with the surface of the output end of the motor 4. After the motor 4 starts, the output end rotates and pushes the bracket 5 to rotate. The rotation of the bracket 5 drives the hot pressing wheel 6 to roll and hot press on the surface of the display screen. A rack 17 is slidably installed on both sides of the bracket 5. The rack 17 meshes with the output end of the second hydraulic rod 3. While the bracket 5 rotates, it pushes the rack 17 to retract. A frame 18 is provided on the surface of the rack 17. The hot pressing wheel 6 is located inside the frame 18. During the retraction of the rack 17, it drives the hot pressing wheel 6 to gradually move closer. The hot pressing wheel 6 hot presses the display screen from the outermost side to the center in sequence, so that the outermost adhesive layer between the cover plate and the substrate is hot-pressed and cooled in advance, and solidifies in advance. The first hydraulic rod 2, the second hydraulic rod 3, the motor 4, and the hot pressing wheel 6 are connected to the control unit. The control unit adjusts the temperature and movement mode of the hot pressing wheel 6 according to the hot pressing steps.

[0026] A third buffer spring 20 is provided between the frame 18 and the bracket 5. The third buffer spring 20 prevents the hot pressure roller 6 from excessively squeezing the surface of the display screen and damaging the display screen. A follower plate 16 is slidably installed on the surface of the short clamp 11. The follower plate 16 serves as the contact medium between the display screen and the short clamp 11, reducing the longitudinal friction between the short clamp 11 and the display screen.

[0027] The strips 14 are parallel to each other and have gaps 21, so that even if the adhesive layer melts and overflows outward during the hot pressing process, the display screen will not easily stick to the outside.

[0028] In this embodiment, after the display screen is positioned, the second hydraulic rod 3 is activated to load the hot pressure roller 6 downwards, causing it to contact the display screen surface. The elastic force of the third buffer spring 20 prevents the hot pressure roller 6 from excessively pressing the display screen surface. After the hot pressure roller 6 contacts the display screen, the control unit heats the hot pressure roller 6 and starts the motor 4. The output end of the motor 4 rotates, driving the bracket 5 to rotate. When the bracket 5 rotates, it drives the heated hot pressure roller 6 to rotate, applying heat pressure to the display screen. When the bracket 5 rotates, it drives the rack 17 to rotate. Because the rack 17 is engaged with the output end of the second hydraulic rod 3, it is limited. Both sides of the rack 17 move towards the middle simultaneously during rotation, causing the hot pressure roller 6 to gradually move closer to the middle, applying heat pressure to the display screen surface from the outside to the inside. After the heat pressure on the display screen surface is completed, the control unit... The unit cools the hot-pressing roller 6 and controls the motor 4 to reverse. As the motor 4 rotates, it drives the hot-pressing roller 6 to rotate, gradually expanding and resetting it outwards. This provides a secondary pressing of the display screen surface, ensuring complete adhesion between the adhesive layer and the cover plate and substrate. The hot-pressing roller 6 presses the display screen sequentially from the outermost edge to the center, allowing the outermost adhesive layer between the cover plate and substrate to be preheated and cooled, solidifying prematurely. This creates a physical barrier against the inner adhesive layer, reducing the loss of adhesive after melting during hot pressing and ensuring full adhesion between the display screen and the adhesive layer. Simultaneously, a gap 21 remains between the upper and lower strips 14 throughout the hot pressing process. Even if the adhesive layer melts and overflows during hot pressing, the overflowing adhesive layer will not stick to the long clamping plate 8, making the display screen easier to remove after hot pressing and preventing it from sticking to the long clamping plate 8 and becoming difficult to detach.

[0029] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, an arc strip 23 is fixedly installed on the surface of the long push plate 7, and a plurality of rotating rods 24 are rotatably installed on the surface of the arc strip 23. Abutment plates 29 are fixedly installed at both ends of the bracket 5. When the bracket 5 rotates, it drives the abutment plates 29 to rotate, and the rotation of the abutment plates 29 pushes the rotating rods 24 to rotate. Baffles 25 are provided on both sides of the rotating rods 24. An arc plate 22 is sleeved at the bottom of the arc strip 23, and the baffles 25 are fixedly installed on the surface of the arc plate 22. After the rotating rods 24 rotate, the bottom pushes the baffles 25, causing the arc plate 22 to move. The arc plate 22 and the arc... A first spring is provided between the strips 23. The elastic force of the first spring causes the arc plate 22 to return to its original position. A slide rod 26 is slidably installed on the surface of the long push plate 7. A protruding rod 27 is fixedly installed at the bottom of the arc plate 22. The protruding rod 27 is sleeved on the surface of the slide rod 26. When the arc plate 22 moves, it drives the protruding rod 27 to press the surface of the slide rod 26, causing the slide rod 26 to move. Arc heads 28 are provided on both sides of the slide rod 26. The movement of the slide rod 26 drives the arc heads 28 to move and press the short push plate 10. By pressing the short push plate 10, the pushing force of the second buffer spring 12 on the short clamping plate 11 is increased, which supplements the clamping force for the display screen.

[0030] The arc head 28 is close to the short push plate 10. A torsion spring is provided between the rotating rod 24 and the arc strip 23. The elastic force of the torsion spring causes the rotating rod 24 to return to its original position. A second spring is provided between the slide rod 26 and the long push plate 7. The elastic force of the second spring causes the slide rod 26 to return to its original position.

[0031] In this embodiment, when the bracket 5 rotates, it drives the two side abutment plates 29 to rotate. After the abutment plates 29 rotate, they contact and push the rotating rod 24 to rotate. After the rotating rod 24 rotates, it drives the arc plate 22 to slide through the bottom push baffle 25. After the arc plate 22 slides, it drives the protruding rod 27 to move, so that the protruding rod 27 continuously slides and squeezes the slide rod 26 on the surface of the slide rod 26, causing the slide rod 26 to move. After the slide rod 26 moves, it drives the arc head 28 to move and push the short push plate 10. By squeezing the short push plate 10, the pushing force of the second buffer spring 12 on the short clamping plate 11 is increased, and the pushing force is supplemented on the surface of the display screen. After the rotating rod 24 rotates, the slide rod 26 will move in the opposite direction of its rotation. In the opposite direction of the movement path of the hot pressing wheel 6, the stress is supplemented on the surface of the display screen, so as to avoid the display screen shaking during the hot pressing process and ensure the stable operation of the hot pressing process.
