Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display panel technology, and in particular to a bonding device. Background Technology

[0002] In the production process of LCD panel manufacturing, substrate transfer usually relies on carriers. The substrate and the pressure plate need to be tightly attached to the carrier by vacuum adsorption. This step has a direct impact on the quality of subsequent processes.

[0003] However, due to the significant weight of the pressure plate, it is prone to downward shifting during the bonding process with the substrate. This shift directly causes the actual bonding area between the pressure plate and the substrate to deviate from the preset requirements, leading to process defects and severely impacting the production quality of the LCD panel. Traditional bonding methods mainly include manual bonding and bonding using positioning pins and fixtures. However, manual bonding is greatly affected by the operator's skill level, experience, and physical strength, making it difficult to guarantee stable bonding accuracy and resulting in low efficiency, which cannot meet the needs of large-scale industrial production. When using positioning pins and fixtures for bonding, the positioning accuracy is often limited by the fixture's machining accuracy and installation errors, similarly making it difficult to overcome the problem of insufficient accuracy. Utility Model Content

[0016] As an alternative solution for a laminating device, the pressing plate is a "return" shaped frame structure. The pressing plate has two marking points, and the two marking points are respectively located at the diagonals of the pressing plate. Any one of the marking points corresponds to one first observation hole, one second observation hole, and one positioning camera.

The motor is fixedly installed on the frame, the output shaft of the motor is connected to the input end of the synchronous displacement component, and the output end of the synchronous displacement component is fixedly connected to the reference plate.

[0019] As an alternative solution for a laminating device, the synchronous displacement component includes a transmission shaft, a turbine, a worm, and at least two lead screws. The transmission shaft is in transmission connection with the output shaft of the motor. The lead screws all extend along the Y direction and are perpendicular to the transmission shaft. The worm is provided on the transmission shaft, and the turbine is correspondingly provided on the lead screw. The worm is engaged with the turbine, and the end of the lead screw far from the turbine is rotatably connected to the reference plate.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] This embodiment provides a bonding device, such as Figures 1-5As shown, a bonding device for bonding a pressure plate 200 to a substrate on a carrier 100 includes a frame 1, a drive assembly 2, an alignment platform 3, an adsorption assembly 4, and a positioning camera 5. The frame 1 has a first opening 11 at its top along the Z direction for accommodating the carrier 100. The drive assembly 2 is fixedly mounted on the frame 1, and its output end is positioned along the Y direction. The alignment platform 3 includes a reference plate 31, an alignment assembly 32, and a carrier plate 33. The reference plate 31 is connected to the output end of the drive assembly 2, and the alignment assembly 32 is positioned between the reference plate 31 and the carrier plate 33. The carrier plate 33 can move along the X and Z directions via the alignment assembly 32. The adsorption assembly 4 is fixedly mounted on the carrier plate 33 for adsorbing the pressure plate 200. The positioning camera 5 is mounted on the reference plate 31, and its lens faces the pressure plate 200. The positioning camera 5 is electrically connected to the alignment assembly 32.

[0041] This bonding device achieves high-precision automatic bonding of the pressure plate 200 and the substrate through the coordinated operation of the frame 1, drive assembly 2, alignment platform 3, adsorption assembly 4, and positioning camera 5. Specifically, the first opening 11 at the top of the frame 1 forms a stable positioning fit with the carrier 100, ensuring the accuracy and reliability of the carrier 100's installation; the drive assembly 2 moves the alignment platform 3 along the Y direction, and, in conjunction with the fine-tuning in the X and Z directions driven by the alignment assembly 32, achieves precise multi-degree-of-freedom control of the pressure plate 200's position; the adsorption assembly 4 reliably fixes the pressure plate 200, preventing positional deviation during bonding; and the positioning camera 5 collects the position of the pressure plate 200 in real time, providing accurate visual feedback for alignment adjustments. This bonding device avoids deviation of the pressure plate 200 from the preset bonding position of the substrate during bonding, improving the alignment accuracy of the pressure plate 200 and the substrate, thereby increasing bonding accuracy and efficiency, and enhancing the stability and reliability of the bonding device's operation.

[0042] In this embodiment, the first opening 11 at the top of the frame 1 is adapted in shape and size to the outer contour of the carrier 100, allowing the carrier 100 to be smoothly inserted in the vertical direction (Z direction). The inner side of the frame 1 is provided with a guide groove or guide protrusion, which forms a sliding fit with the corresponding guide structure on the side of the carrier 100, ensuring the straightness of the carrier 100 during insertion. When the carrier 100 is inserted into place, its bottom contacts and is positioned against the limiting block provided inside the frame 1. Simultaneously, the elastic buckle or pneumatic locking device on the side wall of the frame 1 automatically fixes the position of the carrier 100. This mating structure, through the synergistic effect of mechanical limiting and rapid locking, ensures both the repeatability of the carrier 100's positioning and enables rapid loading and unloading of the carrier 100, effectively improving production cycle time and operational convenience.

[0043] In this embodiment, the alignment component 32 adopts a modular motion mechanism design, consisting of an orthogonal combination of an X-axis motion module and a Z-axis motion module. The X-axis motion module includes a servo motor, a coupling, a ball screw pair, and linear guides. The servo motor is mounted on the side of the reference plate 31 via a flange, and the output shaft of the servo motor is connected to the ball screw via a coupling. The ball screw nut seat is fixedly connected to the bottom of the carrier plate 33, and linear guides are arranged on both sides to ensure smooth movement. The Z-axis motion module adopts the same structure but is arranged rotated 90°. During operation, the control system drives the servo motor to rotate, which in turn drives the ball screw to rotate. The ball screw nut converts the rotational motion into linear displacement, pushing the carrier plate 33 to move along the direction of the linear guides. The encoder at the end of the servo motor shaft provides real-time feedback of position information, which, together with the measurement data from the positioning camera 5, constitutes a closed-loop control system. The servo motor output is adjusted through a control algorithm to ultimately achieve precise positioning of the carrier plate 33 in the XZ plane.

[0044] like Figure 3 As shown, the carrier plate 33 and the lens of the positioning camera 5 are respectively provided with a first observation hole 331 extending through both end faces along the Y direction. The first observation hole 331 can eliminate the obstruction of the light path by the carrier plate 33. The imaging quality of the positioning camera 5 depends on a clear light path. If the carrier plate 33 does not have this hole, its material will block the light from the target to the lens. Whether it is visible light or infrared light, it will lead to the weakening or distortion of the light signal, and ultimately the blurry image or even no image. The first observation hole 331 allows the light to propagate to the lens in a straight line, which satisfies the principle of rectilinear propagation of light and ensures clear imaging, providing a basis for positioning accuracy. Secondly, the design of extending through both ends along the Y direction can adapt to the movement requirements of the carrier plate 33 in the Y direction. When the carrier plate 33 moves along the Y direction, the projection of the optical axis of the camera lens in the Y direction is always within the range of the first observation hole 331, ensuring that the positioning camera 5 can always observe the target through the first observation hole 331 during the entire Y-direction movement of the carrier plate 33.

[0045] like Figure 3As shown, the adsorption assembly 4 includes an adsorption plate 41. A second observation hole 411, corresponding to the first observation hole 331, is formed along the Y direction, penetrating both end faces of the adsorption plate 41. The second observation hole 411 is designed to maintain the unobstructed light path and ensure the normal operation of the positioning camera 5. Specifically, if the adsorption plate 41 lacked the second observation hole 411, it would block the light passing through the first observation hole 331, preventing the positioning camera 5 from forming a clear image. The second observation hole 411, corresponding to the first observation hole 331 and penetrating along the Y direction, allows light to pass smoothly through the adsorption plate 41, ensuring an unobstructed light path from the pressure plate 200 to the camera lens. Furthermore, the Y-direction penetrating design accommodates the movement of the carrier plate 33 and the adsorption plate 41 in the Y direction. Regardless of their movement, the lens of the positioning camera 5 can continuously observe the pressure plate 200 through these two observation holes, ensuring stable positioning and maintaining the accuracy and continuity of positioning by ensuring the light path remains unobstructed during movement.

[0046] Specifically, both the first observation hole 331 and the second observation hole 411 are circular through holes. This ensures that the lens of the positioning camera 5 can acquire uniform light at different angles, avoiding additional diffraction or reflection of light at the edge of the hole due to irregular hole shapes (such as the corners of a square hole), thereby reducing interference with image quality. At the same time, the edges of the circular through holes are smooth curves, allowing for more precise control of dimensions during processing, ensuring that the central axes of the two holes are more easily aligned, avoiding optical path offset caused by hole position deviation, further ensuring the straightness of light propagation, and allowing the positioning camera 5 to always receive a stable light signal, improving the accuracy and stability of positioning. In addition, the circular shape can better adapt to the circular field of view of the camera lens, allowing the effective imaging area of ​​the lens to completely cover the observation hole, avoiding the inability to observe some areas due to mismatch between the shape of the hole and the field of view, ensuring that all key features of the pressure plate 200 can be clearly captured throughout the positioning process.

[0047] like Figure 4As shown, on one end face of the pressing plate 200 facing the adsorption plate 41, there is a marking point 201, and the marking point 201 is located within the orthographic projection area of the second observation hole 411 along the Y direction. This can ensure that the positioning camera 5 can stably and accurately capture the information of the marking point 201, providing a reliable reference for positioning. The marking point 201 is within the orthographic projection area of the second observation hole 411, and the second observation hole 411 corresponds to the first observation hole 331 and both are circular through holes. Light can pass through the first observation hole 331 and the second observation hole 411 in sequence to reach the marking point 201, and then be reflected back to the lens of the positioning camera 5, ensuring that the light reflected by the marking point 201 can smoothly enter the positioning camera 5 and enabling the positioning camera 5 to form a clear image. At the same time, the setting within the orthographic projection area along the Y direction adapts to the movement characteristics of the carrier plate 33 and the adsorption plate 41 along the Y direction. When these components move in the Y direction, the marking point 201 is always within the optical path range of the observation hole and will not move out of the observation field of the positioning camera 5, ensuring that the positioning camera 5 can continuously capture the marking point 201.

[0048] As Figure 4 and Figure 5 shown, the marking point 201 is a cross groove. The intersection point of the cross groove can be used as a clear geometric center. Compared with other shapes (such as a dot), the right-angle characteristics formed by its horizontal and vertical lines are more easily captured by the edge detection algorithm of the positioning camera 5, which can accurately determine the center coordinates of the marking point 201 and reduce the positioning deviation. At the same time, the cross groove structure can enhance the recognition of features through light and shadow contrast. When light shines, the inside of the cross groove shows a dark area due to weak light reflection, and the edge forms a bright area due to strong light reflection. The contrast between light and dark is clear. Even when the ambient light fluctuates, the camera can stably recognize the cross contour and avoid recognition failure caused by insufficient contrast between the marking point 201 and the surrounding area.

[0049] As Figure 4 shown, the pressing plate 200 is a "hui" - shaped frame structure. The pressing plate 200 has two marking points 201, and the two marking points 201 are respectively located at the diagonals of the pressing plate 200. Any one marking point 201 corresponds to a first observation hole 331, a second observation hole 411, and a positioning camera 5. As the bearing foundation, the surface of the substrate often integrates raised structures such as components. The hollow part of the "hui" - shaped pressing plate 200 can accurately avoid these raised parts, making the edge of the "hui" - shaped frame fully fit the flat area of the substrate. The two marking points 201 distributed diagonally, together with their respective corresponding observation holes and the positioning camera 5, form a double - point positioning system. Compared with single - point positioning, it can calculate the planar attitude (such as rotation angle, translation deviation) of the pressing plate 200 through the coordinates of the two points, eliminating the possible direction error in single - point positioning (for example, a single point can only determine the position but cannot judge whether it is tilted), and greatly improving the dimension and accuracy of the overall positioning.

[0050] As Figure 2 As shown, the adsorption component 4 further includes a plurality of suction cups 42. The plurality of suction cups 42 are arranged at intervals on the adsorption plate 41, and the plurality of suction cups 42 are all used to adsorb the pressing plate 200. The spaced distribution of the plurality of suction cups 42 can disperse the adsorption force to multiple points on the pressing plate 200, avoiding local deformation (such as warping and depression) of the pressing plate 200 caused by concentrated force when adsorbing at a single point or a few points, ensuring that the pressing plate 200 remains flat as a whole, and further ensuring that the fitting accuracy between its "square frame" structure and the substrate is not damaged, so that the positions of the marking points 201 at the diagonal corners are stable; at the same time, the suction cups 42 arranged at intervals can form multi-point fixation on the surface of the pressing plate 200. Even if the adsorption force of a certain suction cup 42 decreases due to air leakage, wear, etc., the other suction cups 42 can still maintain the overall adsorption effect, avoiding the pressing plate 200 from falling off or shifting, and ensuring the continuity of the adsorption state.

[0051] As Figure 1 As shown, the driving component 2 includes a motor 21 and a synchronous displacement component 22. The motor 21 is fixedly installed on the frame 1. The output shaft of the motor 21 is connected to the input end of the synchronous displacement component, and the output end of the synchronous displacement component is fixedly connected to the reference plate 31. The motor 21 serves as a power source, which can convert electrical energy into mechanical energy, providing continuous and controllable power for the lifting of the reference plate 31. By adjusting the rotation speed and direction of the motor 21, the moving speed and direction of the reference plate 31 can be accurately controlled to meet the adjustment requirements of the displacement of the reference plate 31 under different working conditions; while the synchronous displacement component 22 can evenly transmit the power of the motor 21 to each force-bearing point of the reference plate 31, ensuring that all parts of the reference plate 31 move synchronously during the lifting process, avoiding tilting or jamming of the reference plate 31 caused by uneven force, and further ensuring the relative positions of the relevant components (such as the carrier plate 33, the adsorption component 4, etc.) installed on the reference plate 31 are stable, preventing positioning deviation caused by the tilting of the reference plate 31.

[0052] As Figure 1As shown, the synchronous displacement assembly 22 includes a drive shaft 221, a worm gear, a worm, and at least two lead screws 222. The drive shaft 221 is connected to the output shaft of the motor 21. The lead screws 222 extend along the Y direction and are perpendicular to the drive shaft 221. The drive shaft 221 is equipped with a worm gear, and the lead screws 222 are equipped with corresponding worm gears. The worm gear meshes with the worm gear, and the end of the lead screw 222 away from the worm gear is rotatably connected to the reference plate 31. The synchronous displacement assembly 22 can accurately realize the synchronous displacement of the reference plate 31, ensuring the stability and consistency of its movement. When the motor 21 drives the drive shaft 221 to rotate, the worm gear on the drive shaft 221 will rotate synchronously. Since the worm gear meshes with the worm gears on each lead screw 222, the rotation of the worm gear will simultaneously drive all the worm gears and the lead screws 222 fixed to them to rotate. The rotatable connection between the lead screw 222 and the reference plate 31 will convert the rotational motion of the lead screw 222 into the linear displacement motion of the reference plate 31 along the Y direction. Since all lead screws 222 are driven by worm gears on the same drive shaft 221, the rotation angle of each worm gear is completely consistent, thus ensuring that the rotation amount of all lead screws 222 is the same, and finally realizing the synchronous lifting and lowering of each connection point of the reference plate 31. This avoids the tilting and jamming problems caused by asynchronous movement of each point when the reference plate 31 moves, and ensures that the reference plate 31 is always in a parallel state with the base plate.

[0053] like Figure 1 As shown, the drive assembly 2, alignment platform 3, adsorption assembly 4, and positioning camera 5 are symmetrically arranged on both sides inside the frame 1. The drive assemblies 2 on both sides are fixedly installed on both sides of the frame 1. The alignment platforms 3 on both sides are connected to the output ends of the corresponding drive assemblies 2. The adsorption assemblies 4 on both sides are fixedly installed on the corresponding alignment platforms 3. The positioning cameras 5 on both sides are installed on the reference plates 31 of the corresponding alignment platforms 3. The adsorption assemblies 4 on both sides adsorb the pressure plates 200. The drive assembly 2, alignment platform 3, adsorption assembly 4, and positioning camera 5 are symmetrically arranged on both sides inside the frame 1, with each component on both sides corresponding to the others. Each adsorption assembly 4 on each side adsorbs one pressure plate 200, so as to achieve the bonding of the pressure plates 200 on both sides of the substrate on the carrier 100, complete the collaborative assembly of the substrate and the two pressure plates 200, and at the same time ensure the stability of the overall structure and the consistency of operation. The symmetrical layout on both sides enables synchronous operation on both sides of the substrate. The driving components 2 on both sides independently drive the alignment platform 3 on the corresponding side, which in turn drives the pressure plate 200 adsorbed by the adsorption component 4 to move. The positioning camera 5 monitors the position information of the pressure plate 200 on the corresponding side, so that the pressure plates 200 on both sides can be accurately aligned with the two edges of the substrate in the same time dimension. This avoids the substrate force imbalance caused by sequential operation on one side (such as substrate offset caused by bonding on one side first), and greatly improves assembly efficiency.
