Description

Technical Field

[0001] This application relates to the field of display assembly technology, and in particular to display assembly apparatus and display assembly system. Background Technology

[0002] With the increasing demand for thinner and lighter display devices and narrower bezels in the consumer electronics market, the internal structure of display modules is constantly evolving. Among them, integrating the backlight module and the rear protective shell into a single backlight structure has become a mainstream technological trend. While this structural innovation brings advantages in volume optimization, it also brings unprecedented challenges to the assembly process: it requires the flexible circuit board of the LCD panel to be precisely bent at 90° before passing it through narrow through-holes pre-drilled in the single-piece backlight shell to achieve final assembly and bonding.

[0003] Currently, most display backlight assembly equipment used in the industry is based on a traditional split-structure design, which cannot effectively meet the aforementioned "bending first, then perforation" process requirements. Existing technologies typically rely on manual operation or semi-automated equipment for this process. Manual operation is not only inefficient but also suffers from numerous drawbacks, including poor consistency in bending angles, difficulty in perforation alignment, and susceptibility to damage to flexible circuit boards due to uneven stress or scratches. These issues directly lead to low assembly precision and unstable yield rates.

[0004] Even in attempts at automation, bending and perforation are often handled as two separate workstations. This separate design leads to the following problems: First, components need to be transferred between different workstations, increasing the risk of positioning error accumulation and surface scratches; second, it is difficult to ensure that the shape of the flexible circuit board after bending can be perfectly aligned with the via at the far end; third, the end position of the flexible circuit board after bending is difficult to control stably, making it prone to swaying and jamming during the perforation process.

[0005] Therefore, there is an urgent need in the field for a fully automated display assembly device that can integrate bending and perforation functions, achieve high-precision alignment and stable transmission, and effectively protect flexible circuit boards from damage, in order to solve the new assembly challenges brought about by the integrated backlight structure. Summary of the Invention

[0006] Therefore, it is necessary to provide a display assembly device and display assembly system to address the problems of difficulty in perforating flexible circuit boards, low precision and efficiency in the assembly of integrated backlight and LCD panel in the prior art.

[0020] In one embodiment, the guiding assembly includes a guide strip and a plurality of guide members disposed on the guide strip. The guide members include a first guide clamp and a second guide clamp, both of which are provided with grooves and L-shaped guide structures.

[0021] When the first guide clamp and the second guide clamp are closed, the groove and the L-shaped guide structure are used to accommodate and guide the flexible circuit board.

[0022] In one embodiment, the display assembly apparatus further includes:

[0023] The second feeding module includes a second mobile platform and a second support platform disposed thereon, and the second feeding module is used to support the display component.

[0034] The aforementioned display assembly device, by employing a bending module combining a moving component with X-axis motion capability and an adsorption panel with Z-axis motion capability, achieves precise adsorption of the display component. This allows the flexible circuit board to pass through the backlight component via a predetermined posture and trajectory, effectively solving the problem of perforation failure caused by insufficient positioning accuracy in traditional assembly methods. Simultaneously, by integrating the bending module and the first feeding module into the same device, the entire process from feeding and positioning to perforation assembly is automated. This not only significantly improves assembly efficiency but also eliminates quality fluctuations caused by manual operation through precise mechanical control, ultimately greatly improving product yield and production stability while ensuring assembly accuracy.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0067] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0068] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0069] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0070] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium.

[0072] See Figure 1 and Figure 2 , Figure 1 and Figure 2A schematic diagram of a display assembly apparatus according to an embodiment of this application is shown. The display assembly apparatus provided in this embodiment includes a bending module 100 and a first loading module 200. The bending module 100 includes a moving component 110 and an adsorption panel 120. The moving component 110 is configured to move in the X direction; the adsorption panel 120 is disposed below the moving component 110 and configured to move in the Z direction, and is used to adsorb the display component 800. The first loading module 200 includes a first moving platform 210 and a first support platform 220 disposed on the first moving platform 210, the first support platform 220 being used to support the backlight component 900. The moving component 110 and the adsorption panel 120 jointly drive the display component 800 to move, so that the flexible circuit board 810 of the display component 800 passes through the backlight component 900 via.

[0073] Through the above structural setup, the bending module 100 and the first loading module 200 form a collaborative overall architecture, achieving high-precision positioning and motion control of the display component 800 and the backlight component 900 during the assembly process. The moving component 110 has X-axis movement capability, enabling the adsorption panel 120 and its adsorbed display component 800 to flexibly adjust their position in the X-axis; the adsorption panel 120 has Z-axis movement capability, enabling the adsorbed display component 800 to flexibly adjust its position in the Z-axis. The adsorption panel 120 and the moving component 110 together ensure that the flexible circuit board 810 has an accurate cutting angle and travel path when passing through the through-hole of the backlight component 900. The first loading module 200, as the carrying and conveying unit of the backlight component 900, achieves precise positioning of the backlight component 900 at the assembly station through the first moving platform 210. The design of the first bearing platform 220 ensures that the backlight component 900 remains stable during conveying and positioning, avoiding assembly failure due to positional deviation. This device, through its modular design and close integration of motion control, not only solves the problem of difficult perforation of flexible circuit boards 810 caused by misalignment and path deviation in traditional assembly processes, but also significantly improves the automation level and consistency of the assembly process.

[0074] Continue reading Figures 3-5 According to some embodiments of this application, the first feeding module 200 further includes an alignment platform 230 and an assembly module 240. Combined with... Figure 6 The alignment platform 230 is mounted on the first mobile platform 210. Combined with... Figure 7 and Figure 8 The assembly module 240 includes a clamping module 241 and a lifting module 242. The clamping module 241 is disposed below the first support platform 220, and the lifting module 242 is disposed on the alignment platform 230 and is positioned opposite to the clamping module 241. Figure 3 and Figure 4As can be seen, the backlight assembly 900 is transported and placed on the first support platform 220, while the display assembly 800 is attracted and transported above the backlight assembly 900 by the adsorption panel 120. Figure 3 The adsorption panel 120 is hidden in the middle. From Figure 5 It can be seen that the backlight assembly 900 has multiple through holes 910, which are evenly distributed on the backlight assembly 900. Figure 5 (Not all through holes 910 are labeled, only the locations of some through holes 910 are shown by way of example.) The flexible circuit board 810 passes through the through holes 910 to be assembled with the backlight assembly 900.

[0075] The alignment platform 230, positioned above the first moving platform 210, forms an independent adjustment station. After the first moving platform 210 transports the backlight component 900 to the assembly area, the alignment platform 230 can perform micron-level precision compensation for its position, effectively eliminating accumulated errors that may occur during previous transport processes. This positioning mechanism significantly improves alignment accuracy, laying a solid foundation for the subsequent precise docking between the display component 800 and the backlight component 900. Figure 6 It should be noted that the alignment platform 230230 includes a first alignment element 231, a second alignment element 232, and a third alignment element 233. The first alignment element 231 and the second alignment element 232 can move linearly in the X1 direction individually or synchronously in the X1 axis direction. This coordinated movement design allows the first alignment element 231 and the second alignment element 232 to work as a whole to quickly and uniformly calibrate the X1 position of the backlight assembly 900. The third alignment element 233 independently performs alignment in the Y direction, and its movement direction is orthogonal to the aforementioned X1 direction. In this way, the three alignment elements together realize a two-dimensional positioning system capable of precise position adjustment in the X1 and Y directions.

[0076] Assembly module 240 is the actuator for the through-hole action of flexible circuit board 810. Clamping module 241 is located below the first support platform 220 and can reliably clamp the flexible circuit board 810 from its bottom after it passes through the through-hole of backlight assembly 900. Lifting module 242 provides an upward lifting force to clamping module 241 from below. Lifting module 242 and clamping module 241 work together to form a stable clamping state. (Continue reading) Figure 7 and Figure 8 In one embodiment, the clamping module 241 includes a slide rail 2411 and a plurality of clamping members 2412 slidably disposed on the slide rail 2411, and the clamping members 2412 are provided with sensors 2413. The lifting module 242 is configured to lift the clamping members 2412 when the sensors 2413 detect the flexible circuit board 810.

[0077] The clamping module 241 is designed to actively clamp and position the flexible circuit board 810 during the perforation process. The introduction of the sensor 2413 enables intelligent triggering of the clamping action, allowing for immediate response when the flexible circuit board 810 reaches a preset position, effectively preventing positional displacement or damage to the flexible circuit board 810 due to premature or delayed clamping. Multiple clamping elements 2412 are slidably arranged along the slide rail 2411, allowing for flexible adjustment based on the actual width of the flexible circuit board 810 and the perforation position, adapting to the assembly requirements of products with different specifications. Furthermore, when the sensor 2413 detects that the flexible circuit board 810 has passed through the through-hole of the backlight assembly 900 and reached the clamping area, the lifting module 242 immediately activates, lifting the clamping element 2412 upwards to contact the lower surface of the flexible circuit board 810 and apply appropriate clamping force. This bottom-lifting clamping method avoids the mechanical damage to the surface circuitry of the flexible circuit board 810 that may be caused by traditional top-down pressing.

[0078] Furthermore, according to some embodiments of this application, the clamping plate 2414 on the clamping member 2412 is designed with a contact surface that matches the shape of the flexible circuit board 810, further enhancing the stability and uniformity of clamping and preventing the flexible circuit board 810 from sliding or twisting in subsequent processes. The entire clamping process is automated and requires no manual intervention, significantly improving the continuity and reliability of the assembly process.

[0079] See Figure 9 In one embodiment, the display assembly apparatus further includes a guide module 300 disposed on the first moving platform 210. The guide module 300 includes a drive mechanism 320 and a guide component 310 disposed on the drive mechanism 320. The guide component 310 is positioned above the clamping module 241 and is used to guide the flexible circuit board 810 as it passes through the backlight assembly 900 via a via. The introduction of the guide module 300 provides precise path guidance for the through-hole process of the flexible circuit board 810, effectively solving the problems of swaying, twisting, or jamming that easily occur during the through-hole process due to the flexibility of the flexible circuit board 810. The drive mechanism 320 can drive the guide component 310 to move precisely to a preset guide position, ensuring that it aligns with the cutting path of the flexible circuit board 810.

[0080] Continue reading Figure 9According to some embodiments of this application, the guide assembly 310 includes a guide strip 311 and multiple sets of guide members 312 disposed on the guide strip 311. Each guide member 312 includes a first guide clamp 3121 and a second guide clamp 3122. Both the first guide clamp 3121 and the second guide clamp 3122 are provided with a groove 3123 and an L-shaped guide structure 3124. When the first guide clamp 3121 and the second guide clamp 3122 are closed, the groove 3123 and the L-shaped guide structure 3124 are used to accommodate and guide the flexible circuit board 810. The guide member 312 adopts a structural design where the first guide clamp 3121 and the second guide clamp 3122 close together to form a guide channel. When the two are closed, the groove 3123 and the L-shaped guide structure 3124 inside together constitute a guide channel that matches the thickness and width of the flexible circuit board 810. The channel not only accommodates the flexible circuit board 810, but also provides limits and support during its passage, effectively constraining the flexible circuit board 810 to move only on a preset straight path, eliminating the possibility of lateral offset and angular deflection.

[0081] This active guiding mechanism significantly improves the success rate and reliability of the perforation process. It compensates for minor deviations that may occur during the alignment of the backlight assembly 900 and the display assembly 800, ensuring that even with some initial positional error, the flexible circuit board 810 can be smoothly guided and pass through the vias on the backlight assembly 900 under the correction of the guiding component 310. Simultaneously, the surface or line contact between the guide 312 and the flexible circuit board 810 disperses the guiding force, avoiding stress concentration, thereby minimizing the risk of scratches or mechanical damage to the surface lines of the flexible circuit board 810. This is crucial for protecting the functional integrity of precision electronic components.

[0082] Combination Figure 10 In one embodiment, the display assembly apparatus further includes a second loading module 400. The second loading module 400 includes a second moving platform 410 and a second support platform 420 disposed thereon. The second loading module 400 is used to carry the display component 800. The introduction of the second loading module 400 establishes a dual loading system, enabling parallel and independent transport of the display component 800 and the backlight component 900. This module serves as a dedicated processing station for the display component 800, transporting it to the gripping area of ​​the bending module 100 via the second moving platform 410, ensuring efficient connection with the main assembly process. This parallel operation mode effectively separates the pre-processing processes of the backlight and display components 800, avoiding mutual interference.

[0083] In one implementation, the second support platform 420 is equipped with a precision mechanical positioning mechanism and vacuum adsorption holes to ensure that the display component 800 maintains a precise and stable posture during transport and subsequent gripping. This is crucial to preventing accidental displacement or damage to the flexible circuit board 810 and provides a reliable reference condition for the subsequent bending component 140 to perform high-precision, repeatable bending operations. Through the coordinated control of the second feeding module 400 and the bending module 100, a fully automated cycle of feeding, positioning, and gripping of the display component 800 is achieved. The existence of this module enables the device to form a continuous working cycle. While the bending module 100 is performing the perforation assembly of the current component, the second feeding module 400 can simultaneously feed and prepare the next display component 800, thereby significantly reducing equipment waiting time, optimizing the overall production cycle, and greatly improving overall production efficiency and capacity.

[0084] Continue reading Figure 1 and Figure 2 In one embodiment, the display assembly apparatus further includes a support frame 500 and a sensing module. The support frame 500 is mounted on the outside of the first moving platform 210. The sensing module includes a first sensing element 510 disposed on the support frame 500 and a second sensing element 421 disposed on the second support platform 420. The first sensing element 510 and the second sensing element 421 are used for visual positioning of the backlight assembly 900 and the display assembly 800, respectively.

[0085] The support frame 500's architecture provides a stable and reliable mounting reference for the first sensing element 510. Its layout, spanning the outside of the first moving platform 210, ensures the first sensing element 510 has a wide field of view and optimal working distance, enabling it to cover the transmission area of ​​the backlight assembly 900 without interference. The sensing module adopts a distributed layout. Through the first sensing element 510 and the second sensing element 421, respectively fixed on the support frame 500 and the second carrier platform 420, synchronous and independent positioning of the backlight assembly 900 and the display assembly 800 is achieved. This design abandons the traditional single-camera moving shooting method. By establishing a unified machine coordinate system, it can acquire the absolute position and attitude angle data of the two components in space in real time. This parallel acquisition mode not only significantly improves alignment efficiency but also avoids calculation deviations caused by component movement or platform repetitive positioning errors. Based on the high-precision image data acquired by the two alignment elements, the system can calculate the relative position and angle deviation between the backlight assembly 900 and the display assembly 800 in real time through a visual processing algorithm. These deviation data are immediately fed back to the system's motion control unit, driving the alignment platform 230 of the first moving platform 210 to perform compensating movements in the X and Y directions. This closed-loop control process lays the technical foundation for the precise and smooth perforation of the flexible circuit board 810 and is key to ensuring the high yield and high reliability of the entire assembly device.

[0086] See Figure 11 In one embodiment, the display assembly apparatus further includes a support component 600. A movable component 110 is mounted on the support component 600 and can move along the support component 600 to transfer the display component 800 from the second feeding module 400 to below the adsorption panel 120. The support component 600 provides a stable and reliable running track and mounting foundation for the movable component 110, ensuring the rigidity and accuracy of the movable component 110 during long-stroke movement. Its straddle-shaped structural design allows the movable component 110 to smoothly transfer over a wide range between the second feeding module 400 and the adsorption panel 120 station, achieving efficient and precise transfer of the display component 800 between different areas. Guided by the support component 600, the movable component 110 drives the adsorption panel 120 below it to perform a smooth linear motion, accurately transporting the display component 800 from the bearing position of the second feeding module 400 to the adsorption panel 120 below the bending module 100 for handover. This process automates the material flow path, closely connecting the feeding station and the assembly station, forming a continuous production cycle. This support and transfer mechanism effectively reduces manual intervention and the time for handling the display component 800 between processes. It not only significantly improves the overall production efficiency, but also avoids the risk of positioning errors or component surface scratches that may be introduced by manual operation through mechanized precise positioning. This provides a reliable material supply guarantee for subsequent precise adsorption, alignment and perforation assembly processes.

[0087] See Figures 11-13 In one embodiment, the bending module 100 further includes a movable connection component 130 and a bending component 140. The movable connection component 130 is disposed on the moving component 110, and the adsorption panel 120 is connected to the moving component 110 through the movable connection component 130. The movable connection component 130, as a movable connection mechanism, has one end fixed to the moving component 110 and the other end movably connected to the adsorption panel 120. The key to this design is that it ensures that the moving component 110 can reliably drive the entire adsorption panel 120 to move synchronously when moving in the X direction, realizing the lifting and lowering between workstations.

[0088] The bending assembly 140 is disposed on the adsorption panel 120 and is used to bend the flexible circuit board 810 of the display assembly 800 by 90°. The bending assembly 140 includes a multi-stage suction nozzle 141 and an adjusting member 142. The multi-stage suction nozzle 141 is configured to adsorb the flexible circuit board 810 individually or together, and the adjusting member 142 drives the multi-stage suction nozzle 141 to rotate, thereby changing the shape of the flexible circuit board 810 to achieve bending. The active rotational bending mechanism of the adjusting member 142 offers greater flexibility and adaptability compared to traditional die bending or passive bending. It can precisely control the starting position, rotation speed, and final angle of bending according to different product specifications and process requirements, ensuring that each flexible circuit board 810 achieves a consistent 90° bend shape that meets design requirements.

[0089] See Figure 14 In one embodiment, the multi-stage suction nozzle 141 includes a first suction nozzle 1411, a third suction nozzle 1413, and a second suction nozzle 1412. These three nozzles are arranged sequentially along the length of the flexible circuit board 810, corresponding to different sections of the flexible circuit board 810. The first suction nozzle 1411 and the second suction nozzle 1412 are typically located near the root of the flexible circuit board 810, and their main function is to provide a stable base fixation during bending, preventing the flexible circuit board 810 from shifting as a whole. The third suction nozzle 1413 acts on the distal free end of the flexible circuit board 810, responsible for accurately positioning the end of the flexible circuit board 810 in the final stage of bending, ensuring that the bent shape meets the preset requirements. (Continue reading...) Figure 15 During the via stage, the adjusting member 142 drives the third suction nozzle 1413 to reset to the same horizontal plane as the first suction nozzle 1411 and the second suction nozzle 1412, thereby eliminating motion interference to the end of the flexible circuit board 810 and ensuring that it can pass through the via of the backlight assembly 900 smoothly and straight.

[0090] Combination Figure 16 and Figure 17Driven by the adjusting component 142, the three suction nozzles can rotate sequentially or synchronously according to a preset program, lifting the originally flat flexible circuit board 810 ( Figure 16 The image shows the state of the multi-stage suction nozzle 141 when the flexible circuit board 810 is horizontal. Because it is a side view, the secondary suction nozzle is obscured by the primary suction nozzle. The nozzle is gradually and controllably bent at a 90° angle. Figure 17 This is a side view of the multi-stage suction nozzle 141 when the flexible circuit board 810 is bent at 90° (the second-stage nozzle is obscured by the first-stage nozzle). The coordinated operation of the multi-stage suction nozzle 141 not only significantly improves the stability and repeatability of the bending process, but more importantly, it effectively disperses bending stress, preventing wrinkles, tensile deformation, or micro-cracks from forming on the surface of the flexible circuit board 810. Thus, while completing the mechanical forming, it maximizes the protection of the integrity of the precision circuit.

[0091] It should be noted that when the flexible circuit board 810 of the display component 800 is transported to the second loading module 400, it can be in two initial states: one is a pre-bent state, that is, it has completed a 90° bend; the other is a horizontal, unbent state. This device has the ability to handle both states. For the horizontal flexible circuit board 810, the device will complete a precise 90° bend before performing the via process using the bending component 140, and then guide it through the via of the backlight component 900; for the already bent flexible circuit board 810, it can be directly assembled with the backlight component 900.

[0092] The core advantage of the display assembly apparatus described in this application lies in its highly coordinated automated process, which integrates multiple key processes such as bending, alignment, and perforation into a single unit, thereby achieving high-precision, high-efficiency, and high-reliability assembly of the flexible circuit board 810. Its core workflow is as follows:

[0093] First, in the initial adsorption and preparation stage, the display component 800 is conveyed to a predetermined position by the second feeding module 400, and the moving component 110 of the bending module 100 moves the adsorption panel 120 above it. The adsorption panel 120 descends in the Z direction and, together with the multi-stage suction nozzles 141 on it, adsorbs the flexible circuit board 810, which is in a horizontal state. At this time, the first feeding module 200 has also conveyed the backlight component 900 to the assembly station, and the vision alignment system is activated simultaneously to accurately position the two and eliminate relative positional deviations.

[0094] Subsequently, the bending and forming stage begins. The core of this stage lies in the coordinated movement of the multi-stage suction nozzles driven by the adjusting component. Specifically, the first, second, and third suction nozzles begin to rotate under the drive of the adjusting component, jointly guiding the bending curvature of the flexible circuit board to the target angle.

[0095] Subsequently, the bending and forming stage begins. The core of this stage lies in the coordinated movement of the multi-stage suction nozzles 141 driven by the adjusting member 142. Specifically, the first suction nozzle 1411, the second suction nozzle 1412, and the third suction nozzle 1413 begin to rotate under the drive of the adjusting member 142, jointly guiding the bending curvature of the flexible circuit board 810 to the target angle.

[0096] Then, the device enters the guiding and perforating stage. After bending, to meet the perforation path requirements, the adjusting component 142 drives the third suction nozzle 1413 to rotate in the opposite direction, resetting it to a state approximately coplanar with the first suction nozzle 1411 and the second suction nozzle 1412. This is to eliminate the interference of the suction nozzle itself on the straight-line movement of the end of the flexible circuit board 810. Immediately afterwards, the moving component 110 and the adsorption panel 120 work together to carry the display component 800, which has been bent to 90°, closer to the backlight component 900. Just before the end of the flexible circuit board 810 is about to enter the through hole of the backlight component 900, the guiding module 300 starts to operate, and its driving mechanism 320 causes the first guide clamp 3121 and the second guide clamp 3122 to close. After closing, the groove 3123 on its inner side and the L-shaped guide structure 3124 together form a precision guiding channel that closely matches the thickness and width of the flexible circuit board 810. When the end of the flexible circuit board 810 contacts the guide channel during the advancement process, the L-shaped guide structure 3124 can provide three-dimensional positioning from its sides and top. Any slight lateral deviation will be corrected by the inner wall of the guide 312, thereby forcing the flexible circuit board 810 to move along the preset straight path, ensuring that it can be accurately introduced and smoothly pass through the via on the backlight assembly 900.

[0097] Finally, during the clamping and fixing stage, when the flexible circuit board 810 successfully passes through the through hole 910 and reaches the preset depth, the sensor 2413 on the clamping module 241 detects the arrival of the flexible circuit board 810 and sends a signal. The lifting module 242 then moves upward, lifting the clamping member 2412 to firmly clamp the flexible circuit board 810 from below. Subsequently, the clamping member 2412 moves downward as a whole, which applies a downward pulling force to the flexible circuit board 810 to make it pass completely through the through hole 910. At the same time, the upper adsorption panel 120 moves downward synchronously, applying a precise downward pressure, and the display component 800 is smoothly and reliably pressed onto the backlight component 900, completing the final assembly.

[0098] This application also provides a display screen assembly system, including the aforementioned display screen assembly device. By integrating the display screen assembly device, this system constructs a complete automated production line, capable of realizing the entire process from loading and precisely aligning the display components 800 and backlight components 900, bending the flexible circuit board 810, to final perforation assembly. This integrated system solution greatly reduces manual intervention, effectively lowering labor costs and fundamentally avoiding quality fluctuations caused by improper manual operation. Simultaneously, the system possesses excellent flexible production capabilities; through program adjustments and modular configuration, it can adapt to the assembly needs of display screen products of different specifications and sizes, providing the display screen manufacturing industry with an efficient, reliable, and highly adaptable automated solution.
