Description

Technical Field

[0001] This application relates to the field of OLED screen manufacturing technology, and in particular to a fully automated OLED screen bonding device. Background Technology

[0002] OLED screens are widely used in 3C products due to their excellent display performance and design flexibility. OLED screens can achieve true blacks and infinite contrast, and feature wide viewing angles and fast response times, making them suitable for displaying fast-moving images while reducing ghosting and blur. Furthermore, the flexibility of OLED screens allows them to be used in foldable devices and curved displays, expanding the possibilities for product design.

[0003] 3C products refer to a collective term for three categories of electronic products: computers, communication devices, and consumer electronics. These products are typically characterized by ease of operation, high practicality, inclusion of key PC functions, and close integration with traditional home appliances through software, telecommunications networks, and electronic information technology. The range of 3C products is very broad, including but not limited to personal computers, smartphones, tablets, digital cameras, smart wearable devices, and gaming devices.

[0004] With the development of technology, 3C products use bonding equipment to bond screens. However, in existing technology, bonding equipment is generally placed on a machine and the screen is bonded by the automatic movement of the bonding machine. However, the movement of the machine during the bonding process can easily cause the machine to shift, resulting in deviations after bonding. This leads to an increased defect rate of finished products and economic losses. Utility Model Content

[0005] In order to overcome the problems existing in the prior art, this application provides a fully automatic OLED screen bonding device.

[0006] The fully automated OLED screen bonding equipment provided in this application adopts the following technical solution: A fully automatic OLED screen bonding device includes a base and a mounting frame. The mounting groove at the top of the base is provided with a limiting mechanism for clamping the device to be bonded. The limiting mechanism includes a ring of clamping plates, which are interlaced. The clamping plates are driven by an outer driving mechanism to stably clamp the device to be bonded. A power mechanism is installed at the top of the mounting frame. The power mechanism drives the bonding plate with the screen adsorbed on it to bond with the device to be bonded. The output end of the power mechanism is also connected to the driving mechanism.

[0007] By adopting the above technical solution, the fully automatic OLED screen bonding equipment first places the 3C device to be bonded in the limiting mechanism within the mounting slot at the top of the base. Then, the power mechanism at the top of the mounting frame is activated. Its output first drives the drive mechanisms on the outer sides of the circularly distributed and intersecting clamping plates in the limiting mechanism, causing the clamping plates to move inward synchronously, thus forming a stable clamp on the device to be bonded and preventing the device from shifting during subsequent bonding. After clamping and fixing, the power mechanism continues to operate, driving the bonding plate with the OLED screen adsorbed to move precisely downward until the bonding plate contacts the clamped and fixed device to be bonded, completing the screen bonding operation. The entire process achieves fully automatic coordinated operation from device fixing to screen bonding.

[0008] Preferably, the clamping plate is an I-shaped plate and a cross-shaped plate, wherein the I-shaped plate and the cross-shaped plate are distributed alternately.

[0009] Preferably, the drive mechanism includes a drive rod connected to the clamping plate, the end of the drive rod away from the clamping plate being hinged to an action rod on the base via a linkage rod, wherein the action rod and the drive rod are horizontally distributed, and the action rod is connected to the output end of the power mechanism.

[0010] Preferably, the bottom surface of the mounting groove is provided with a groove for accommodating the drive rod, wherein the drive rod includes a cavity for connecting the clamping plate and a rod body slidably installed in the cavity, and the part of the rod body located in the cavity is provided with a baffle, and the opening end of the cavity is provided with a retaining ring for limiting the baffle, and the baffle is connected to the end of the cavity away from the opening by a spring.

[0011] Preferably, one end of the actuating rod is hinged to the linkage rod, and the other end is fitted onto a guide rod perpendicular to the base and connected to the actuating rods of other drive mechanisms on the base via a rectangular frame. The top center of the actuating rod is connected to the output end of the power mechanism.

[0012] By adopting the above technical solution, after the film-applying equipment is placed in the mounting slot, the output end of the power mechanism drives the rectangular frame, causing each action rod connected to the rectangular frame to move vertically along the guide rod. As the action rods move, they push the drive rod to slide horizontally within the groove via the linkage rod. Because the clamping plates, which are spaced apart by the I-beam and cross-shaped plates, are connected to their corresponding drive rods, the drive rods cause the clamping plates to move synchronously closer to the equipment. The drive rod slides within the cavity, and the spring within the cavity is compressed by the baffle. The retaining ring limits the baffle to prevent the rod from detaching from the cavity, ensuring that the spring force provides cushioning when the clamping plate contacts the equipment, allowing the I-beam and cross-shaped plates to stably clamp the equipment and complete the clamping action. When release is required, the power mechanism drives the action rod to move in the opposite direction, the linkage rod pulls the drive rod to reset, and the spring rebound helps the drive rod return to its initial position, thus releasing the clamping plate from the equipment.

[0013] Preferably, the mounting frame has an inlet and an outlet at both ends, and a track for conveying the film-coating plate is provided along the direction from the inlet to the outlet. The film-coating plate is lifted and installed at the center of the moving plate by the mounting column at its top, and the stop block at the top of the mounting column is connected to the moving plate by a spring. The bottom of the moving plate moves on the track by a slider. A heating plate is installed at the bottom of the film-coating plate, and a pressure sensor and a temperature sensor are also provided on the film-coating plate.

[0014] Preferably, the power mechanism is a cylinder, and the free end of the cylinder output shaft is provided with an action block, wherein the bottom center of the action block is provided with a positioning groove that matches the stop block, and L-shaped rods connected to the drive mechanism are symmetrically installed on both sides of the action block.

[0015] Preferably, a lifting mechanism for ejecting the equipment is installed at the bottom center of the base, including a lifting cylinder and a lifting plate installed at the output end of the lifting cylinder.

[0016] By adopting the above technical solution, the film-applying plate enters the track through the feed inlet. An external power structure or a structure that drives a moving plate on the track can be used. The moving plate moves along the track via a slider, transporting the film-applying plate above the equipment to be applied. At this point, the cylinder is activated, and its output shaft drives the actuating block downwards. The L-shaped rods on both sides of the actuating block synchronously drive the drive mechanism, clamping and fixing the equipment to be applied. Simultaneously, the positioning groove at the bottom center of the actuating block mates with the stop block on the top mounting column of the film-applying plate. As the actuating block continues to move downwards, the stop block compresses the spring, pushing the film-applying plate downwards to appliqué the equipment. During the appliqué process, a pressure sensor monitors the appliqué pressure, and a temperature sensor monitors the heating temperature of the heating plate to ensure the appliqué effect. After appliqué is completed, the cylinder output shaft drives the actuating block upwards, the spring returns to reset the film-applying plate, and the moving plate sends the film-applying plate out of the discharge port along the track. Subsequently, the lifting cylinder at the bottom of the base drives the lifting plate upwards, pushing the appliquéd equipment out of the mounting slot.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. This application uses a ring-shaped, cross-shaped clamping plate as a limiting mechanism, which can stably clamp the film-applying device under the action of the driving mechanism, effectively avoiding the offset caused by the movement of the device during the screen application process. The clamping plate adopts an alternating distribution of I-shaped and cross-shaped plates, which further improves the stability and adaptability of the clamping.

[0018] 2. The drive mechanism in this application is linked with the power mechanism through structures such as drive rods, linkage rods, and action rods, so that while the power mechanism drives the film-applying plate to descend and apply, it simultaneously drives the clamping plate to clamp the device, ensuring that the application and clamping actions are coordinated, reducing application deviation, and the spring structure inside the drive rod can provide buffering to avoid excessive clamping force from damaging the equipment.

[0019] 3. This application uses a track-driven film-laying plate combined with a heating plate, pressure sensor, and temperature sensor to precisely control the temperature and pressure during the lamination process. Combined with a lifting mechanism, it facilitates the placement and removal of equipment, significantly reducing screen lamination deviation, improving the finished product qualification rate, reducing economic losses, and enhancing the automation and production efficiency of OLED screen lamination for 3C products.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a fully automated OLED screen bonding device.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A fully automatic OLED screen bonding device includes a base 1 and a mounting frame 2. A limiting mechanism 3 for clamping a device to be bonded is provided in a mounting groove 11 at the top of the base 1. The limiting mechanism 3 includes ring-shaped clamping plates 31, which are interlaced. The clamping plates 31 are driven by an outer driving mechanism 32 to stably clamp the device to be bonded. A power mechanism 21 is mounted on the top of the mounting frame 2. The power mechanism 21 drives a bonding plate 22 with a screen attached to it to bond with the device to be bonded. The output end of the power mechanism 21 is also connected to the driving mechanism 32. When the fully automatic OLED screen bonding device is working, the 3C device to be bonded is first placed in the limiting mechanism 3 in the mounting groove 11 at the top of the base 1. Subsequently, the power mechanism 21 at the top of the mounting frame 2 is activated. Its output end first drives the driving mechanism 32 on the outer side of the ring-shaped and interlaced clamping plates 31 in the limiting mechanism 3, causing the clamping plates 31 to move inward synchronously, thereby forming a stable clamp on the device to be bonded and preventing the device from shifting during subsequent bonding. After clamping and fixing, the power mechanism 21 continues to operate, driving the film plate 22 with the OLED screen adsorbed to move down precisely until the film plate 22 contacts the clamped and fixed device to be filmed and completes the screen bonding operation. The whole process realizes fully automatic coordinated operation from device fixing to screen bonding.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The clamping plate 31 comprises an I-shaped plate 311 and a cross-shaped plate 312, wherein the I-shaped plate 311 and the cross-shaped plate 312 are spaced apart. The driving mechanism 32 includes a driving rod 321 connected to the clamping plate 31. The end of the driving rod 321 away from the clamping plate 31 is hinged to an action rod 323 on the base 1 via a linkage rod 322. The action rod 323 is horizontally distributed with the driving rod 321, and the action rod 323 is connected to the output end of the power mechanism 21. The bottom surface of the mounting slot 11 has a groove 111 for accommodating the drive rod 321. The drive rod 321 includes a cavity 3211 that connects to the clamping plate 31 and a rod 3212 that is slidably installed in the cavity 3211. The portion of the rod 3212 located in the cavity 3211 is provided with a baffle 3213. The open end of the cavity 3211 is provided with a retaining ring 3214 that limits the position of the baffle 3213. The baffle 3213 is connected to the end of the cavity 3211 away from the opening by a spring. One end of the actuating rod 323 is hinged to the linkage rod 322, and the other end is fitted onto a guide rod 12 perpendicular to the base 1 and connected to the actuating rods 323 of other drive mechanisms 32 on the base 1 through a rectangular frame 324. The top center of the actuating rod 323 is connected to the output end of the power mechanism 21. After the film-applying device is placed in the mounting slot 11, the output end of the power mechanism 21 drives the rectangular frame 324, causing the actuating rods 323 connected to the rectangular frame 324 to move vertically along the guide rod 12. As the actuating rods 323 move, they push the drive rods 321 to slide horizontally within the groove 111 via the linkage rod 322. Since the clamping plates 31, which are spaced apart by the I-beam plate 311 and the cross-shaped plate 312, are connected to their corresponding drive rods 321, the drive rods 321 will drive the clamping plates 31 to synchronously approach the device. The rod body 3212 of the drive rod 321 slides within the cavity 3211. The spring within the cavity 3211 is compressed by the baffle 3213, and the retaining ring 3214 limits the baffle 3213 to prevent the rod body 3212 from detaching from the cavity 3211. This ensures that when the clamping plate 31 contacts the device, the spring force provides cushioning, allowing the I-beam plate 311 and the cross-shaped plate 312 to stably clamp the device, completing the clamping action. When it is necessary to release, the power mechanism 21 drives the action rod 323 to move in the opposite direction, the linkage rod 322 pulls the drive rod 321 to reset, the spring rebound helps the drive rod 321 return to the initial position, and the clamping plate 31 releases the equipment.

[0027] Reference Figure 1 , Figure 2 and Figure 3The mounting frame 2 has an inlet and an outlet at both ends, and a track 23 for conveying the film-coating plate 22 is provided along the direction from the inlet to the outlet. The film-coating plate 22 is mounted on the center of the moving plate 222 by a mounting column 221 at its top. The stop block 2211 at the top of the mounting column 221 is connected to the moving plate 222 by a spring. The bottom of the moving plate 222 moves on the track 23 by a slider 2221. A heating plate 24 is installed at the bottom of the film-coating plate 22. A pressure sensor 25 and a temperature sensor 26 are also provided on the film-coating plate 22. The power mechanism 21 is a cylinder. The free end of the cylinder output shaft is provided with an action block 211. The bottom center of the action block 211 is provided with a positioning groove 2111 that matches the stop block 2211. L-shaped rods 2112 connected to the drive mechanism 32 are symmetrically installed on both sides of the action block 211. A lifting mechanism 13 for ejecting the equipment is installed at the bottom center of the base 1, including a lifting cylinder 131 and a lifting plate 132 installed at the output end of the lifting cylinder 131. The film-applying plate 22 enters the track 23 through the feed port. An external power structure or a structure that drives the moving plate 222 to move on the track 23 can be used. The moving plate 222 moves along the track 23 through the slider 2221, which drives the film-applying plate 22 to be transported above the equipment to be applied. At this time, the cylinder is activated, and its output shaft drives the actuating block 211 to move down. The L-shaped rods 2112 on both sides of the actuating block 211 synchronously drive the drive mechanism 32, so that the clamping plate 31 clamps and fixes the equipment to be applied. At the same time, the positioning groove 2111 at the bottom center of the actuating block 2111 is adapted to engage with the stop block 2211 on the top mounting column 221 of the film-applying plate 22. As the actuating block 211 continues to move down, the stop block 2211 compresses the spring, pushing the film-applying plate 22 down to apply to the equipment. During the bonding process, pressure sensor 25 monitors the bonding pressure, and temperature sensor 26 monitors the heating temperature of heating plate 24 to ensure bonding effect. After bonding is completed, cylinder output shaft drives action block 211 to move upward, spring returns to reset film plate 22, moving plate 222 sends film plate 22 out of discharge port along track 23, and then lifting cylinder 131 at the bottom of base 1 drives lifting plate 132 to move upward, pushing the bonded equipment out of mounting slot 11.

[0028] Working principle: First, the device to be applied is placed in the limiting mechanism 3 within the mounting slot 11 at the top of the base 1. The power mechanism 21 is activated, and its output drives the drive mechanism 32. The action rod 323 in the drive mechanism 32 pushes the drive rod 321 through the linkage rod 322, causing the clamping plates 31, which are arranged in a circumferential pattern with the I-shaped plate 311 and the cross-shaped plate 312, to move towards the center. The elastic force of the springs stably clamps the device to be applied. At the same time, the power mechanism 21 drives the film-applying plate 22 with the OLED screen attached, which is then conveyed to the bonding position via the track 23. The bottom of the base 22 has a heating plate 24 and is equipped with pressure and temperature sensors 26. The film-applying plate 22 moves downward. As the film-applying plate 22 approaches the device to be film-applied, the drive mechanism 32 continuously maintains the stable clamping state of the clamping plate 31 to prevent the device from shifting. When the film-applying plate 22 contacts the device to be film-applied and completes the application, the power mechanism 21 drives the film-applying plate 22 to reset. At the same time, the action rod 323 of the drive mechanism 32 resets, and the clamping plate 31 releases the device to be film-applied under the action of the spring. Finally, the lifting mechanism 13 at the bottom of the base 1 pushes out the applied device, completing one application operation.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
