Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0019] The rear panel assembly 1 includes a rear panel 11 and an optical assembly 12, which may include a diffuser 121 and an optical film 122. The rear panel assembly 1 may also include components such as LED strips and reflectors.

[0020] The back panel assembly 1 is an important component of the display device. When assembling the back panel assembly 1, the back panel 11, optical components 12, lamp strips, reflective sheets and other components can be assembled together using an automated production line for the display device and in conjunction with display device manufacturing methods.

[0021] It should be noted that the driving component mentioned in this application can be a double-speed chain mechanism, a cylinder driving mechanism, a motor driving mechanism, or a robotic arm driving mechanism. The suction component mentioned in this application can be a suction nozzle or any other suitable component with suction function.

[0022] The following is combined with Figure 1 and Figure 32 This application describes an automated production line for a display device, a back panel assembly, and a manufacturing method thereof.

[0023] The following is a description of the rear panel assembly 1: In some embodiments, see Figure 1 and Figure 2 The rear panel assembly 1 includes a rear panel 11, an optical component 12, and an adhesive portion. The rear panel 11 includes two opposing inner sidewalls 111, and the adhesive portion is disposed on the inner sidewalls 111 and located between the inner sidewalls 111 and the optical component 12.

[0024] Understandably, the optical component 12 is housed within the receiving space of the back panel 11, and the optical component 12 is isolated and buffered from the inner sidewall 111 by an adhesive portion. That is, the adhesive portion is located between the inner sidewall 111 and the optical component 12, preventing the optical component 12 from directly contacting the hard inner sidewall 111 of the back panel 11. Because the adhesive portion is elastic, direct scratching between the optical component 12 and the inner sidewall 111 of the back panel 11 is avoided. During subsequent handling, assembly, or transportation, even if the optical component 12 experiences slight shaking or displacement, the adhesive portion can effectively buffer and dampen it, preventing scratches to the optical component 12.

[0025] Understandably, compared to related technologies that use separate adhesive foam pasted onto the sidewalls of the back panel 11, this embodiment eliminates the need for material preparation, cutting, and pasting of the adhesive foam by directly setting the adhesive portion on the inner sidewall 111. This results in a simpler structure and higher production efficiency. Furthermore, the directly cured adhesive portion bonds firmly to the back panel 11, eliminating the risk of detachment and providing a uniform and continuous buffer surface, thus offering more reliable and comprehensive protection for the optical components 12.

[0026] In some examples, the optical component 12 includes at least a diffuser plate 121 and an optical film 122 disposed on the diffuser plate 121.

[0027] In some examples, the adhesive is applied directly to the inner wall 111 by dispensing or coating and extends along the length of the inner wall 111.

[0028] In some examples, the inner wall 111 refers to the left inner wall and the right inner wall.

[0029] In some embodiments, see Figure 1 and Figure 3 The rear panel assembly 1 includes a rear panel 11, connectors and multiple PCBs, with PCBs 13 connected to the rear panel 11 and different PCBs 13 connected by connectors 14.

[0030] It is understood that connectors 14 are used to achieve electrical connections between different PCBs 13. Specifically, matching pairs of connectors 14 are provided on the PCBs 13 that need to be interconnected, such as the male and female connectors of board-to-board connectors 14. By directly plugging these connectors 14 together, the circuit connection between the PCBs 13 can be completed, thereby reducing the use of wires in traditional solutions.

[0031] By using connector 14 for direct board-to-board connections, the number of internal wirings in the backplane assembly 1 is reduced. This helps reduce electromagnetic compatibility (EMC) interference that may be introduced by wiring and makes the internal routing cleaner. At the same time, compared to wire connections which typically require space between PCBs 13, the connector 14 insertion method allows PCBs 13 to be arranged with smaller spacing, resulting in a more compact overall structure. This compact design allows for a reduction in the overall size of the backplane 11, contributing to material cost savings.

[0032] Specifically, the multiple PCB boards 13 include a power board 131, a decoder board 132, and a TCON board 133, and the connector 14 includes a first mating connector 141 and a second mating connector 142. The first mating connector 141 connects the power board 131 and the decoder board 132, and the second mating connector 142 connects the power board 131 and the TCON board 133.

[0033] Understandably, by replacing the traditional connecting wires between the power board 131 and the decoder board 132, and between the power board 131 and the TCON board 133, with the first pair of connectors 141 and the second pair of connectors 142, the number of cables is reduced, which helps to simplify wiring, reduce electromagnetic interference that may be caused by cables, and make the layout more orderly. At the same time, the connector 14 mating method reduces the space required for wiring, allowing the power board 131, decoder board 132 and TCON board 133 to be arranged more closely, which helps to achieve a compact design of the back panel assembly 1 structure.

[0034] In some embodiments, see Figure 3 The back panel 11 has a positioning protrusion 112, which is connected to the PCB board 13 and is used to position the PCB board 13.

[0035] Understandably, by fitting the positioning holes on the PCB board 13 onto the positioning protrusions 112 on the back panel 11, the initial horizontal positioning and limiting of the PCB board 13 can be achieved. Afterward, the PCB board 13 can be finally fixed to the back panel 11 using screws or other fasteners.

[0036] In some examples, the number of positioning protrusions 112 can be two or more. For example, providing at least one positioning protrusion 112 at each diagonal of the PCB board 13 can ensure the positioning effect of the PCB board 13.

[0037] In some embodiments, the back panel 11 has a snap-fit ​​portion that snaps into the PCB board 13. In this way, after the snap-fit ​​portion snaps into the PCB board 13, it can position the PCB board 13, so that the PCB board 13 and the back panel 11 remain relatively stable, so as to facilitate the subsequent fixed connection of the PCB board 13 and the back panel 11 by screws or other fasteners.

[0038] In some embodiments, the back panel assembly 1 further includes a fastener 15, and a first connection hole is formed on the back panel 11. A second connection hole corresponding to the first connection hole is formed on the PCB board 13.

[0039] Fasteners, such as screws or bolts, can be inserted into the first connection hole and the second connection hole to connect the PCB board 13 to the back panel 11.

[0040] Along the length and / or width of the backplate 11, the diameter of the first connecting hole is set to be larger than the diameter of the fastener shank through which it is inserted. This results in a horizontal gap between the shank of the fastener and the inner wall of the first connecting hole after the fastener is inserted.

[0041] In the assembled and shipped state, fasteners pass through the first and second connecting holes, serving to connect and pre-position the components, preventing the PCB board 13 from detaching from the back panel 11. Simultaneously, because the diameter of the first connecting hole is larger than the fastener diameter in at least one horizontal direction, the PCB board 13 is not completely locked relative to the back panel 11 in that direction (length and / or width), but rather has a certain amount of sliding travel. This design allows the PCB board 13 to buffer some external forces during transportation through slight positional movement, and provides the necessary adjustment margin for precise alignment with other components (such as another PCB board 13 mated with connector 14) during final assembly. This enables the back panel assembly 1 to be conveniently and reliably shipped and subsequently assembled in SKD (semi-knock-down) form.

[0042] The following is an introduction to the automated production line for display devices: In some embodiments, see Figure 4An automated production line for display devices includes a conveyor 2, which carries the back panel 11 and drives the back panel 11 to move. The automated production line for display devices also includes a back panel dispensing device 3, a light strip feeding device 4, a reflective sheet feeding device 5, a top-side dispensing device 6, an optical component feeding device 7, and a display screen mounting device 8, which are arranged sequentially along the moving direction of the back panel 11. The back panel dispensing device 3 is used to dispense adhesive onto both sides of the back panel 11, the light strip feeding device 4 is used to install the light strip onto the back panel 11, the reflector feeding device 5 is used to install the reflector onto the back panel 11, the top side dispensing device 6 is used to dispense adhesive onto the top side of the back panel 11, the optical component feeding device 7 is used to install the optical component 12 onto the back panel 11, and the display screen mounting device 8 is used to install the display screen onto the back panel 11.

[0043] Understandably, the back panel dispensing device 3 is located at the beginning of the production line and is used to automatically dispense adhesive onto the two sides (left and right sides) of the back panel 11 brought up by the conveyor 2, forming adhesive strips for buffering and positioning the optical components 12. The LED strip loading device 4 is located downstream of the back panel dispensing device 3 and is used to automatically pick up the LED strip and install it onto the designated position on the back panel 11 after the side dispensing has been completed.

[0044] The reflector feeding device 5 is located downstream of the light strip feeding device 4 and is used to automatically pick up the reflector and install it onto the back panel 11 on which the light strip has been installed. The top side glue dispensing device 6 is located downstream of the reflector feeding device 5 and is used to automatically dispense glue onto the top side (upper side) of the back panel 11 on which the reflector has been installed, forming a glue path for load-bearing bonding.

[0045] The optical component loading device 7 is located downstream of the top-side dispensing device 6. It is used to automatically pick up the optical component 12, which is composed of the diffuser plate 121 and the multilayer optical film 122, and install it into the back panel 11, which has already been dispensed at the top side. The display screen mounting device 8 is located at the end of the production line. It is used to automatically cover and press the liquid crystal glass panel onto the back panel assembly 1, which has already been installed with the optical component 12, to form a complete display module.

[0046] In this way, several key processes that originally relied on manual operation, such as back panel adhesive application, LED strip installation, reflector installation, top side adhesive application, optical component 12 installation, and display screen cover assembly, are integrated into a continuous automated process, improving the automation level and overall production efficiency of display device production.

[0047] In some examples, the conveyor 2 may be a double-speed chain, belt conveyor, or roller conveyor. The conveyor 2 is used to carry the back panel 11, which serves as the assembly base, and drives the back panel 11 sequentially through each station on the production line according to a set rhythm and speed.

[0048] In some examples, the display screen is, for example, a glass display screen or any other suitable type of display screen.

[0049] In some embodiments, see Figure 4 The automated production line for display devices also includes an automatic screw fastening device 9, and an optical component loading device 7 located between the automatic screw fastening device 9 and the display mounting device 8. The automatic screw fastening device 9 is used to connect the PCB board 13 and the back panel 11 together with screws.

[0050] It is understandable that PCB boards 13, such as power board 131 and decoder board 132, are generally required to be installed at the back panel 11. In this embodiment, the PCB board 13 and the back panel 11 are fixed by screws through the automatic screw locking device 9, which realizes the automatic locking connection between the PCB board 13 and the back panel 11 and improves the degree of automation.

[0051] The dispensing device is described in detail below: In some embodiments, the dispensing device may be a back panel dispensing device 3, a top-side dispensing device 6, or a display screen dispensing device. See also... Figure 5 , Figure 6 and Figure 7 The dispensing device includes a first dispensing drive 31, a second dispensing drive 32, a third dispensing drive 33, and a dispensing component 34. The second dispensing drive 32 is connected to the first dispensing drive 31, and the first dispensing drive 31 drives the second dispensing drive 32 to move along a first direction. The third dispensing drive 33 is connected to the second dispensing drive 32, and the second dispensing drive 32 drives the third dispensing drive 33 to move along a second direction. The dispensing component 34 is connected to the third dispensing drive 33, and the third dispensing drive 33 drives the dispensing component 34 to move along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0052] It is understandable that the first dispensing drive 31, the second dispensing drive 32 and the third dispensing drive 33 together constitute a motion mechanism that can be independently controlled in three mutually perpendicular directions in three-dimensional space. This mechanism can drive the dispensing component 34 to any specified position within the working range and move according to a preset trajectory, thereby completing the automatic dispensing operation on different workpieces (such as the side of the back panel 11, the top side or the display screen frame), improving the degree of automation and production efficiency.

[0053] Specifically, when the dispensing device is the back panel dispensing device 3, the dispensing component 34 is used to dispense adhesive on the inner side wall 111 of the back panel 11. In this way, an adhesive portion can be formed on the inner side wall 111 of the back panel 11, and the adhesive portion can be used to separate the optical component 12 from the inner side wall 111 of the back panel 11, thus preventing damage to the optical component 12.

[0054] Specifically, when the dispensing device is the top-side dispensing device 6, the dispensing component 34 is used to dispense adhesive at the top side of the back panel 11.

[0055] Specifically, when the dispensing device is a display screen dispensing device, the dispensing component 34 is used to dispense adhesive on the side of the back panel 11 away from the conveyor component 2, that is, at the edge of the back panel 11. This can also be understood as dispensing adhesive on the end face of the back panel 11 away from the conveyor component 2. After the display screen dispensing device completes the dispensing operation, the display screen mounting device 8 installs the display screen onto the side of the back panel 11 away from the conveyor component 2, using adhesive to connect the display screen and the back panel 11 together, thus achieving automatic installation of the display screen and improving automation and production efficiency.

[0056] In some embodiments, see Figure 6 and Figure 7 The dispensing component 34 includes a dispensing body 341 and a dispensing head 342, with the first end of the dispensing head 342 connected to the dispensing body 341. When the dispensing device is a back panel dispensing device 3, the second end of the dispensing head 342 extends in the horizontal direction.

[0057] Understandably, when this dispensing device is configured and used as the back panel dispensing device 3, the second end (i.e., the dispensing end) of the dispensing head 342 is set to extend horizontally. This means that in the standby and working states of the dispensing operation, the dispensing direction of the dispensing head 342 is approximately horizontal, rather than vertically downward.

[0058] In actual operation, the back panel 11 is usually conveyed and fixed with its surface perpendicular to the horizontal plane (i.e., vertical). By setting the dispensing head 342 to extend horizontally, the dispensing head 342 can directly and directly face the side wall (inner side wall 111) of the back panel 11. The motion mechanism drives the entire dispensing component 34 to move, bringing the horizontally extending dispensing head 342 close to the side wall of the back panel 11, thus facilitating the dispensing operation on the side wall surface to form the required adhesive strip. This setting simplifies the dispensing trajectory planning and avoids the need for complex adjustments to the posture of the back panel 11 or the dispensing path to accommodate the vertical dispensing head 342, thereby facilitating efficient and accurate dispensing on both sides of the back panel 11.

[0059] Specifically, the back panel dispensing device 3 also includes a dispensing rotating component, which is connected to the third dispensing drive component 33. The dispensing component 34 is connected to the dispensing rotating component. The dispensing rotating component is used to drive the dispensing component 34 to rotate, so as to change the orientation of the dispensing head 342.

[0060] Understandably, the dispensing rotary component can rotate around an axis (such as a vertical or horizontal axis), thereby causing the dispensing component 34 connected to it to rotate as a whole. When the dispensing rotary component moves, the horizontal extension direction of the dispensing head 342 fixed on the dispensing component 34 changes accordingly, that is, its orientation deflects in the horizontal plane.

[0061] When adhesive needs to be applied to the left side wall of a back panel 11, the adhesive dispensing rotating component drives the adhesive dispensing component 34 to rotate, so that the adhesive dispensing head 342 faces the left side wall. After the adhesive application to the left side wall is completed, the adhesive dispensing rotating component drives the adhesive dispensing component 34 to rotate, so that the direction of the adhesive dispensing head 342 can be changed to face the right side wall of the back panel 11, thereby enabling the adhesive application to continue to the right side wall.

[0062] By setting up a dispensing rotating component, a single dispensing device is able to adjust the horizontal orientation of the dispensing head 342, thus eliminating the need for two sets of dispensing mechanisms to sequentially dispense adhesive to the two oppositely positioned sidewalls on the back panel 11. This simplifies the equipment structure and improves the flexibility and efficiency of the dispensing operation.

[0063] In some embodiments, see Figure 6 The dispensing device also includes at least two parallel dispensing guides 35, a second dispensing drive 32 slidably connected to the dispensing guides 35, and a first dispensing drive 31 for driving the second dispensing drive 32 to move along the dispensing guides 35.

[0064] Understandably, the first dispensing drive 31 is used to provide driving force along the first direction. The second dispensing drive 32 is slidably connected to at least two mutually parallel dispensing guides 35. The dispensing guides 35 extend along the first direction to provide guidance and support for the movement of the second dispensing drive 32.

[0065] The first dispensing drive 31 is connected to the second dispensing drive 32, and is used to drive the second dispensing drive 32 to move smoothly back and forth along the dispensing guide 35, thereby realizing linear motion along the first direction.

[0066] The third dispensing drive 33 is connected to the second dispensing drive 32 and is driven by it to move along the first direction. The third dispensing drive 33 is used to drive the dispensing component 34 to move along a third direction perpendicular to the first direction.

[0067] By setting at least two parallel dispensing guides 35 and forming a sliding connection with the second dispensing drive 32, the structural rigidity and motion stability of the second dispensing drive 32 and its subsequent components (the third dispensing drive 33 and the dispensing component 34) are enhanced when moving along the first direction, which helps to ensure the positional accuracy of the dispensing operation.

[0068] In some examples, the dispensing guide 35 is, for example, a guide rail or a slide bar.

[0069] In some embodiments, see Figure 6 and Figure 7 The dispensing device also includes a first position sensor 36 and a first position trigger 37. The first position sensor 36 is disposed on the dispensing guide 35, and the first position trigger 37 is connected to the second dispensing drive 32. The first position sensor 36 is located on the movement path of the first position trigger 37.

[0070] Understandably, during the movement of the second dispensing drive 32 along the dispensing guide 35 driven by the first dispensing drive 31, when the first position trigger 37 connected to it moves to the sensing area of ​​the first position sensor 36, the first position sensor 36 is triggered and generates a corresponding detection signal. This signal can be used to indicate whether the second dispensing drive 32 (and its subsequent components) has reached or passed a certain set reference position, thereby providing position feedback for the motion control of the dispensing device.

[0071] By setting the first position sensor 36 and the first position trigger 37, the stroke position of the key moving part (second dispensing drive 32) of the dispensing device is detected and monitored, which helps to improve the reliability of motion control and the repeatability of positioning accuracy.

[0072] In some embodiments, the back panel dispensing device 3 further includes a slider and a position detection element. The slider is slidably connected to the dispensing guide 35, the second dispensing drive 32 is connected to the slider, and the position detection element is connected to the slider. The position detection element is used to detect the position of the slider.

[0073] Understandably, when the first dispensing drive 31 drives the second dispensing drive 32, the slider slides on the dispensing guide 35. A position detection element connected to the slider continuously or intermittently detects its own position (i.e., the slider) and feeds this position signal back to the control system. Based on the received real-time position signal, the control system can perform precise closed-loop control of the movement of the first dispensing drive 31, thereby ensuring that the second dispensing drive 32 and its subsequent components (such as the third dispensing drive 33 and the dispensing head 342) can accurately and repeatedly reach the preset working position.

[0074] By directly mounting the position detection component on the slider rigidly connected to the second dispensing drive component 32, direct and accurate measurement and feedback of the position of the end of the drive component's movement are achieved. This direct detection method helps reduce errors that may be caused by intermediate transmission links, providing accurate positional basis for the spatial positioning of the dispensing head 342, thereby ensuring the accuracy of the final dispensing trajectory and position.

[0075] In some examples, the position detection element is, for example, a magnetic grating reading head or a position sensor connected to the slider.

[0076] In some embodiments, see Figure 8 and Figure 9 The back panel dispensing device 3 also includes a curing drive 38 and a curing component 39. The curing component 39 is connected to the curing drive 38. The curing drive 38 is used to drive the curing component 39 to move relative to the dispensing position of the dispensing component 34. The curing component 39 is used to cure the adhesive at the dispensing position.

[0077] Understandably, during or after the dispensing operation, the curing drive 38 moves the curing assembly 39 to an area above or adjacent to the dispensing location. Subsequently, the curing assembly 39 is activated to apply a curing effect to the uncured adhesive at the dispensing location, for example, by emitting ultraviolet light or generating heat, to promote the curing of the adhesive.

[0078] By setting up independent curing drive components 38 and curing components 39, and enabling them to follow or position to the dispensing location, this embodiment achieves immediate, targeted curing of the adhesive after the dispensing process. This helps to shorten the adhesive's curing time, stabilize the bonding effect, and may reduce defects caused by interference with the adhesive in its flowing state, thus improving the overall reliability of the process.

[0079] In some embodiments, see Figure 5 The back panel dispensing device 3 also includes a frame 30, on which the first dispensing drive component 31 is mounted. This provides support for the first dispensing drive component 31.

[0080] The following is a detailed description of the light strip feeding device 4: In some embodiments, see Figure 10 and Figure 11 The light strip feeding device 4 includes a light strip storage component 41, a feeding drive component 43, and a feeding assembly 44. The light strip storage component 41 has a light strip bearing surface 42, which is used to bear multiple light strips and is connected to the feeding drive component 43. The feeding drive component 43 is used to drive the feeding assembly 44 to move between the light strip bearing surface 42 and the back plate 11, so that the feeding assembly 44 can move the light strips at the light strip bearing surface 42 to the back plate 11.

[0081] Understandably, the feeding drive 43 moves the feeding assembly 44 above the light strip bearing surface 42, so that the feeding assembly 44 (e.g., through a suction nozzle or clamp on it) can pick up one or more light strips. Then, the feeding drive 43 moves the feeding assembly 44, which has picked up the light strip, above the back panel 11 and places and installs the light strip at a predetermined position on the back panel 11.

[0082] Through the coordinated operation of the LED strip storage component 41, the feeding drive component 43, and the feeding assembly 44, this embodiment achieves automatic picking, placing, and transferring of LED strips from the storage position to the installation position on the back panel 11. This replaces the traditional manual picking, placing, and positioning of LED strips, realizing automatic installation of LED strips and improving the degree of automation and production efficiency.

[0083] In some embodiments, see Figure 10 and Figure 11 The feeding assembly 44 includes a telescopic drive 441 and a plurality of LED strip adsorption components 442 arranged side by side. The telescopic drive 441 is connected to the feeding drive 43, and the LED strip adsorption components 442 are connected to the telescopic drive 441. The telescopic drive 441 is used to drive the LED strip adsorption components 442 to extend and retract relative to the bearing surface and / or the back plate 11. Each LED strip adsorption component 442 can be used to pick up LED strips.

[0084] Understandably, the telescopic drive 441 causes multiple LED strip adsorption components 442 to extend, allowing each adsorption component 442 to contact and perform a suction operation on the corresponding LED strips on the LED strip bearing surface 42. Subsequently, the telescopic drive 441 retracts, raising the adsorption component with the adsorption of multiple LED strips to a safe height. At the placement station, after the loading drive 43 moves the assembly above the back panel 11, the telescopic drive 441 again causes the adsorption component with the adsorption of LED strips to extend, placing and positioning the multiple LED strips in the designated installation area of ​​the back panel 11.

[0085] By employing multiple LED strip adsorption components 442 arranged side-by-side and driven by the same telescopic drive component 441, this embodiment achieves synchronous pickup of multiple LED strips, which helps to improve the feeding cycle time. The telescopic drive component 441 ensures that the adsorption components have independent and controllable vertical movement strokes during pickup and placement, which not only guarantees the reliability of the picking and placing actions but also avoids unnecessary impact on the LED strips or the back panel 11.

[0086] In some examples, in addition to using the light strip adsorption component 442 to pick up the light strip, clamps or other gripping components can also be used to grip the light strip.

[0087] In some embodiments, see Figure 10 and Figure 11 The light strip adsorption component 442 includes a mounting component 4421 and a plurality of light strip suction nozzles 4422. The mounting component 4421 is connected to the telescopic drive component 441, and the light strip suction nozzles 4422 are connected to the mounting component 4421. The plurality of light strip suction nozzles 4422 are distributed sequentially at intervals along the length direction of the mounting component 4421.

[0088] Thus, when the light strip needs to be picked up, the telescopic drive 441 lowers the mounting piece 4421 and the multiple light strip suction nozzles 4422 connected to it. Multiple light strip suction nozzles 4422, spaced apart along the length of the mounting piece 4421, simultaneously contact the surface of the light strip and adhere it using negative pressure. This multi-point adsorption method allows the long, narrow light strip to be gripped evenly and stably, helping to prevent bending, shifting, or detachment during transport. When installing the light strip onto the back panel 11, the coordinated action of the multiple light strip suction nozzles 4422 ensures that the light strip is placed smoothly and accurately in the predetermined position.

[0089] By employing a light strip adsorption component 442 structure with a specific mounting component 4421 and spaced light strip suction nozzles 4422, effective and reliable gripping and release of light strips is achieved, ensuring the stability and accuracy of automatic feeding.

[0090] In some embodiments, see Figure 10 and Figure 11 The light strip adsorption component 442 also includes a positioning post 4423, which is connected to the mounting component 4421 and is used to insert into the positioning hole in the light strip mounting area of ​​the back panel 11.

[0091] Understandably, when the feeding assembly 44, carrying the adsorbed LED strip, moves above the back panel 11 and is ready for placement, the telescopic drive 441 lowers the mounting component 4421. During this process, the positioning post 4423 connected to the mounting component 4421 first contacts the back panel 11 and is guided into the positioning hole at the LED strip installation area. Through the insertion and engagement of the positioning post 4423 and the positioning hole, the feeding assembly 44 is precisely positioned and constrained in the horizontal direction relative to the back panel 11. Subsequently, the LED strip suction nozzle 4422 releases the LED strip, allowing it to be installed in the determined precise position.

[0092] By setting positioning posts 4423 on the mounting component 4421 that match the positioning holes of the rear panel 11, this embodiment achieves active guidance and precise positioning before placement at the mechanical level. This physical positioning method reduces the dependence on the absolute positioning accuracy of the drive system, effectively overcomes the cumulative error and possible deviations in visual alignment, thereby ensuring the accuracy and consistency of the light strip installation position.

[0093] Specifically, the end of the positioning post 4423 that is opposite to the mounting piece 4421 protrudes from the light strip nozzle 4422.

[0094] Understandably, during installation, when the feeding assembly 44 lowers with the adsorbed LED strip for placement, the protruding end of the positioning post 4423 will contact the surface of the back panel 11 before the LED strip suction nozzle 4422. If the positioning post 4423 can be smoothly inserted into the corresponding positioning hole on the back panel 11, the mounting component 4421 can continue to descend, allowing the LED strip suction nozzle 4422 to reach the height required to release the LED strip, thus completing the installation. If the positioning post 4423 fails to be inserted into the positioning hole due to positional deviation or other reasons, its protruding end will be blocked by the surface of the back panel 11, preventing the entire mounting component 4421 from descending to the predetermined position. In this case, the LED strip suction nozzle 4422 cannot place the LED strip onto the back panel 11 due to insufficient height, thus physically preventing the LED strip from being forcibly installed in an inaccurate positioning state.

[0095] By configuring the positioning post 4423 to protrude from the light strip nozzle 4422, this embodiment makes the positioning post 4423 a mechanical prerequisite for the placement action to be completed. This structure provides a simple and reliable error-proofing mechanism, ensuring that the light strip installation steps can only be performed under the premise of accurate positioning, thereby guaranteeing the accuracy of the installation operation.

[0096] In some embodiments, see Figure 11 The feeding assembly 44 also includes a mounting frame 443, which is connected to the feeding drive component 43, and the telescopic drive component 441 is connected to the mounting frame 443. The feeding assembly 44 also includes a guide sleeve 445 and a light strip guide 446. The guide sleeve 445 is connected to the mounting bracket 443. The guide sleeve 445 has a guide hole. The light strip guide 446 passes through the guide hole and is slidably connected to the hole wall of the guide hole. The light strip guide 446 is connected to the mounting component 4421.

[0097] Understandably, when the telescopic drive 441 drives the mounting component 4421 and the light strip adsorption component 442 to extend or retract, the light strip guide 446 connected to the mounting component 4421 will slide synchronously within the guide hole of the guide sleeve 445. The sliding engagement between the guide hole and the light strip guide 446 provides additional lateral support and guidance for the mounting component 4421 and the light strip adsorbed on it during the telescopic movement, restricting their movement path and helping to reduce swaying and offset.

[0098] By setting a sliding guide structure consisting of guide sleeve 445 and light strip guide 446, this embodiment enhances the motion rigidity and straightness of the feeding assembly 44 during the process of picking up and placing light strips, providing a more stable motion guarantee for the accurate picking and installation of light strips.

[0099] In some embodiments, see Figure 11The feeding assembly 44 also includes a second position trigger 447 and at least two second position sensors 448, with the first end of the second position trigger 447 connected to the mounting member 4421; Along the movement path of the second end of the second position trigger 447 when the telescopic drive 441 drives the mounting piece 4421 to extend or retract, at least two second position sensors 448 are distributed sequentially at intervals.

[0100] Thus, during operation, when the telescopic drive 441 extends or retracts the mounting member 4421, the second position trigger 447 connected to it moves accordingly. When the second end of the second position trigger 447 moves to the sensing area of ​​a second position sensor 448, the sensor is triggered and generates a signal. Since at least two sensors are spaced apart along the path, they can each correspond to different specific positions in the movement stroke of the mounting member 4421, such as the fully retracted position, the fully extended position, or a transitional position in between. These position signals can be used for feedback control to confirm whether the material handling or unloading action is in place, or for safety interlocking.

[0101] By setting a second position trigger 447 that is linked to the mounting component 4421 and a plurality of second position sensors 448 distributed along its path, this embodiment realizes the detection and monitoring of multiple key positions in the extension and retraction stroke of the feeding component 44, providing position feedback basis for precise control of the picking and placing actions.

[0102] In some embodiments, see Figure 10 , Figure 11 and Figure 30 The light strip storage unit 41 includes a storage frame 411 and a plurality of storage trays 412 stacked sequentially on the storage frame 411. The storage trays 412 are formed with storage slots for storing light strips. The light strip feeding device 4 also includes a feeding component 45, which is connected to the feeding drive 43. The feeding drive 43 is used to drive the feeding component 45 to move relative to the light strip storage component 41. The feeding component 45 is used to move the storage tray to a designated position.

[0103] Understandably, during operation, once the LED strips in the lower storage tray have been used by the feeding component 44, the feeding drive 43 can move the unloading component 45 to the empty storage tray. The unloading component 45 performs actions (e.g., lifting, clamping, or pushing) to remove the empty storage tray from the stacking sequence of the storage rack 411 and transfer it to a designated recycling location or conveyor line. Subsequently, the upper storage tray descends or remains in place, becoming a new station awaiting material removal.

[0104] By incorporating a light strip storage component 41 with a stacked storage tray and a corresponding unloading component 45, this embodiment achieves batch storage of light strip raw materials and automatic removal of empty trays. This structure facilitates continuous operation of the production line, reduces downtime caused by manual tray replacement, and improves the automation level of material management.

[0105] For details, please refer to Figure 10 and Figure 11 The unloading assembly 45 includes an unloading drive 451 and an unloading nozzle 452. The unloading drive 451 is connected to the loading assembly 44, and the unloading nozzle 452 is connected to the unloading drive 451. The unloading drive 451 is used to drive the unloading nozzle 452 to extend and retract relative to the storage rack 411.

[0106] Understandably, during operation, when an empty storage tray needs to be removed, the loading drive 43 first moves the entire unloading assembly 45, positioning the unloading nozzle 452 above the target storage tray. Then, the unloading drive 451 extends the unloading nozzle 452, bringing it into contact with the surface of the storage tray. The unloading nozzle 452 activates and holds the storage tray. Next, the unloading drive 451 retracts the unloading nozzle 452, lifting the storage tray from the stack of the storage rack 411. Finally, the loading drive 43 moves the unloading assembly 45 to the designated recycling position, and the unloading nozzle 452 releases the storage tray, completing the unloading operation.

[0107] By employing a feeding nozzle 452 driven by a feeding drive 451, this embodiment achieves automatic, non-contact gripping and transfer of empty storage trays. The structure is simple and easy to integrate into the light strip feeding device 4, which helps to automate the management of light strip material trays.

[0108] The following is a detailed description of the reflective sheet feeding device 5: In some embodiments, see Figure 12 and Figure 13 The reflective sheet feeding device 5 includes a reflective sheet storage component 51, a reflective sheet driving component 52, a first adsorption component 53, and a second adsorption component 54. The reflective sheet storage component 51 is used to store reflective sheets. The first adsorption component 53 is connected to the reflective sheet driving component 52, and the reflective sheet driving component 52 is used to drive the first adsorption component 53 to move between the reflective sheet storage component 51 and the back plate 11. The second adsorption component 54 is rotatably connected to the first adsorption component 53, and the second adsorption component 54 can be switched between at least a first state and a second state. In the first state, the second adsorption component 54 is horizontally arranged, and in the second state, the second adsorption component 54 is inclined relative to the first adsorption component 53. The first adsorption component 53 and the second adsorption component 54 are used to pick up different positions of the reflective sheet.

[0109] Understandably, during operation, the reflector drive 52 first moves the first adsorption assembly 53 and the second adsorption assembly 54, which are in the first state (horizontal state), above the reflector storage assembly 51. The two adsorption assemblies operate independently, jointly adsorbing a reflector 140. The first adsorption assembly 53 adsorbs the main body area of ​​the reflector, while the second adsorption assembly 54 adsorbs the edge area of ​​the reflector 140 that needs to be bent. After adsorption, the reflector drive 52 lifts the assembly and moves it to the workstation. During the movement or after reaching above the back panel 11, the second adsorption assembly 54 is controlled to switch from the first state to the second state (tilted state). Since the edge of the reflector 140 is fixed by the second adsorption assembly 54, this rotation causes the corresponding edge of the reflector 140 to bend, thus forming a pre-shaped reflector that matches the internal structure of the back panel 11. Finally, the reflector drive 52 lowers the assembly, accurately placing the pre-bent reflector 140 into a predetermined position within the back panel 11.

[0110] By incorporating relatively rotatable first and second adsorption components 54, this embodiment achieves continuous operation of picking up, pre-bending, and placing the reflective sheet within a single loading station. This device allows the reflective sheet to be bent into a suitable shape before installation, simplifying the subsequent steps of bending or adjusting the reflective sheet on-site during assembly. This makes the installation of the reflective sheet more convenient and helps improve assembly accuracy and efficiency.

[0111] For details, please refer to [link / reference]. Figure 27 , Figure 28 and Figure 29 . Figure 27 The reflector 140 is in its unbent state. Figure 29 This is a schematic diagram of a rear panel assembly with a reflector 140 installed, wherein the reflector 140 is in a bent state.

[0112] In some embodiments, see Figure 13 and Figure 14 The reflective sheet feeding device 5 also includes a first bending drive 55, which is installed on the first adsorption assembly 53. The second adsorption assembly 54 includes a bending plate 541 and a first bending adsorption member 542. The first bending adsorption member 542 is connected to the bending plate 541 and is used to pick up the reflective sheet. The first bending drive 55 is connected to the bending plate 541 and is used to drive the bending plate 541 to rotate relative to the first adsorption assembly 53.

[0113] Understandably, when it is necessary to change the state of the second adsorption component 54, the first bending drive 55 is activated, driving the bending plate 541 to rotate around its axis of rotation. This causes the first bending adsorption component 542 connected to the bending plate 541 and the reflective sheet portion it adsorbs to change from a horizontal state to an inclined state, or from an inclined state back to a horizontal state, thereby achieving pre-bending or flattening of the reflective sheet.

[0114] By setting up a dedicated first bending drive 55 and a bending plate 541 with adsorption function that is rotatably connected to the first adsorption component 53, this embodiment provides a well-defined and directly driven solution, realizing reliable control of the attitude of a local area of ​​the reflective sheet and providing a basis for the pre-forming operation of the reflective sheet.

[0115] In some examples, the bending plate 541 is rotatably connected to the first adsorption assembly 53 via a structure such as a pivot or hinge. The output end of the first bending drive 55 (e.g., the piston rod of a cylinder or the output shaft of a motor) is coupled to the bending plate 541 via a connecting rod, gear, or direct connection.

[0116] In some embodiments, see Figure 13 There are multiple second adsorption components 54, and the multiple second adsorption components 54 are arranged around the first adsorption component 53.

[0117] Understandably, when the first adsorption component 53 and the multiple second adsorption components 54 arranged around it jointly adsorb a reflective sheet, the first adsorption component 53 is responsible for adsorbing the center or main body area of ​​the reflective sheet, while the multiple second adsorption components 54 respectively adsorb the edge areas of the reflective sheet in different directions. Subsequently, these second adsorption components 54 can be driven by their respective driving components to rotate independently or synchronously to different tilt angles as needed, thereby bending multiple edges of the reflective sheet into the desired shape simultaneously.

[0118] By setting multiple second adsorption components 54 distributed around the first adsorption component 53, this embodiment enables the device to perform independent adsorption and bending operations on multiple edges or specific areas of the reflective sheet, thereby adapting to the more complex structure inside the back panel 11, realizing multi-directional pre-forming of the reflective sheet, and improving the adaptability and efficiency of processing complex-shaped reflective sheets.

[0119] In some examples, multiple second adsorption components 54 may be distributed at circumferential intervals along the first adsorption component 53, or arranged respectively corresponding to different edge directions of the reflective sheet to be bent.

[0120] In some embodiments, see Figure 13 and Figure 14The reflective sheet feeding device 5 also includes a second bending adsorption member 56, which is disposed between two adjacent second adsorption components 54 and is used to pick up the reflective sheet.

[0121] Understandably, when the first adsorption component 53 and multiple second adsorption components 54 jointly adsorb a reflective sheet, the second bending adsorption component 56 also participates in the adsorption process. Specifically, the second bending adsorption component 56 can adsorb the portion of the reflective sheet located between the edge areas covered by two adjacent second adsorption components 54. When multiple second adsorption components 54 rotate to bend the edge of the reflective sheet, the second bending adsorption component 56 enhances the fixation of the intermediate transition area of ​​the reflective sheet, helping to maintain the overall flatness and shape controllability of the reflective sheet during the bending process, and reducing wrinkles or displacement caused by local uncontrolled areas.

[0122] By adding a second bending adsorption element 56 between adjacent second adsorption components 54, this embodiment increases the number and distribution density of adsorption points on the surface of the reflective sheet, thereby improving the adsorption and fixation effect on the reflective sheet, especially its non-edge areas, and providing a more reliable guarantee for completing complex or precise bending and forming operations.

[0123] In some embodiments, see Figure 13 and Figure 14 The reflective sheet feeding device 5 also includes a second bending drive 58, and a second bending adsorption member 56 is rotatably connected to one of the two adjacent second adsorption components 54. The second bending drive 58 is connected to the second bending adsorption member 56, and the second bending drive 58 is used to drive the second bending adsorption member 56 to rotate.

[0124] Understandably, after the second bending adsorption component 56 picks up the reflective sheet, it can be independently rotated as needed by the second bending drive component 58. This allows the reflective sheet area located between two adjacent main bending edges to also undergo a certain angle of bending or attitude adjustment under controlled conditions. For example, when two adjacent second adsorption components 54 rotate to bend the two sides of the reflective sheet, the second bending adsorption component 56 located between them can rotate synchronously or as needed to guide the transition area to form a smooth or specific curved shape, thereby achieving more complex and precise three-dimensional shaping control of the reflective sheet.

[0125] By making the second bending adsorption member 56 rotatable and driven by an independent second bending drive member 58, this embodiment enhances the active shaping capability of the non-edge area of ​​the reflector, so that the pre-bending shape of the reflector can better adapt to the complex three-dimensional structure inside the back panel 11.

[0126] In some embodiments, see Figure 13 and Figure 14The first adsorption component 53 includes an adsorption plate 531 and a plurality of reflective sheet nozzles 532. The adsorption plate 531 is connected to the reflective sheet drive component 52, and the plurality of reflective sheet nozzles 532 are spaced apart on the adsorption plate 531.

[0127] Understandably, during operation, the reflector drive 52 moves the adsorption plate 531 above the reflector storage unit 51. Multiple reflector suction nozzles 532 on the adsorption plate 531 work together to adsorb the main body area of ​​the reflector. The spaced distribution of the multiple reflector suction nozzles 532 provides a uniform and stable adsorption force to the reflector, supporting subsequent handling and coordinated operation with the second adsorption assembly 54.

[0128] By employing a structure with an adsorption plate 531 and spaced-apart reflective sheet suction nozzles 532, this embodiment provides a reliable and easy-to-implement solution for the first adsorption component 53, achieving effective gripping and fixing of the main body area of ​​the reflective sheet.

[0129] In some embodiments, see Figure 12 and Figure 13 The reflector storage component 51 has a reflector bearing surface 511, which is used to bear the reflector. The reflective sheet feeding device 5 also includes a position adjustment component 57, which is connected to the reflective sheet storage component 51. The position adjustment component 57 can move relative to the reflective sheet bearing surface 511 in at least one direction to drive the reflective sheet on the reflective sheet bearing surface 511 to a designated position.

[0130] Understandably, when the reflective sheet is placed on the reflective sheet support surface 511, its initial position may be deviated. The position adjustment component 57 operates according to a preset command or a signal fed back by visual detection, driving its actuator to contact and move the reflective sheet on the support surface, thereby fine-tuning the reflective sheet from its initial position to a precise designated position. This designated position typically corresponds to the preset gripping position when the first adsorption component 53 comes to pick it up.

[0131] By setting the position adjustment component 57, this embodiment enables the reflective sheet to complete precise position correction at the storage station, ensuring the accuracy and reliability of subsequent suction actions and providing a guarantee for the stability of the entire feeding process.

[0132] In some embodiments, see Figure 12 and Figure 13The position adjustment assembly 57 includes a horizontal drive 571, a vertical drive 572, and an adjustment plate 573. The horizontal drive 571 is connected to the reflector storage unit 51, the vertical drive 572 is connected to the horizontal drive 571, and the adjustment plate 573 is connected to the vertical drive 572. The horizontal drive 571 is used to drive the vertical drive 572 to move horizontally relative to the reflector bearing surface 511, and the vertical drive 572 is used to drive the adjustment plate 573 to move vertically relative to the reflector bearing surface 511.

[0133] Understandably, the vertical drive unit 572 drives the adjusting plate 573 to descend, causing its side or end to press against one edge of a stack of reflective sheets piled on the reflective sheet support surface 511. Continued pressure causes the stack of reflective sheets to tilt as a whole, and causes slight staggered displacement between adjacent reflective sheets due to friction and gravity, thus achieving physical separation and ensuring that the topmost reflective sheet is effectively separated from the others. Then, the horizontal drive unit 571 actuates, moving the adjusting plate 573 horizontally, thereby pushing the separated topmost reflective sheet to slide onto the reflective sheet support surface 511 to a preset, precise gripping position.

[0134] Through the coordinated action of the horizontal drive member 571 and the vertical drive member 572, and with the help of the structure of the adjustment plate 573, the position adjustment component 57 of this embodiment can not only achieve precise positioning of the reflective sheet, but more importantly, it can effectively separate the stacked reflective sheets, ensuring that only a single reflective sheet is moved to the target position each time, thereby avoiding the problem of multiple sheets being picked up at the same time or sticking together that may occur during the feeding process.

[0135] The following is a description of the optical component loading device: In some embodiments, see Figure 15 The optical component loading device 7 includes a diffuser plate loading machine 71 and an optical film loading machine arranged sequentially along the moving direction of the back plate 11. The diffuser plate loading machine 71 is used to install the diffuser plate 121 onto the back plate 11, and the optical film loading machine is used to stack the optical film 122 onto the diffuser plate 121.

[0136] Understandably, the backplate 11, after the top-side adhesive is applied, is transported by the conveyor 2 and first arrives at the diffuser plate loading machine 71. The diffuser plate loading machine 71 performs an action, precisely placing a diffuser plate 121 into a preset position within the backplate 11. Subsequently, the backplate 11 continues to move to the downstream optical film loading machine station. The optical film loading machine performs an action, picking up multiple layers of optical films 122 sequentially or in groups, and stacking them onto the positioned diffuser plate 121 to form a complete optical assembly 12.

[0137] By breaking down the installation process of the optical component 12 into two independent steps—the loading of the diffuser plate 121 and the loading of the optical film 122—and sequentially setting up corresponding dedicated equipment along the production line flow, this embodiment achieves step-by-step, automated assembly of the optical component 12. This sequential arrangement conforms to the stacking logic of optical components, facilitates the adoption of targeted loading strategies for two components with different characteristics, helps ensure installation accuracy, avoids component damage, and optimizes production cycle time.

[0138] In some embodiments, see Figure 15 The diffuser plate feeder 71 includes a diffuser plate storage component 72, a diffuser plate driving component 73, and a diffuser plate adsorption component 74; The diffuser plate storage component 72 has a diffuser plate bearing surface 721, which is used to support the diffuser plate 121. The diffuser plate drive 73 is connected to the diffuser plate adsorption component 74. The diffuser plate drive 73 is used to drive the diffuser plate adsorption component 74 to move between the diffuser plate bearing surface 721 and the back plate 11. The diffuser plate adsorption component 74 is used to absorb the diffuser plate 121.

[0139] Understandably, during operation, the diffuser drive 73 first moves the diffuser suction component 74 above the diffuser bearing surface 721 of the diffuser storage component 72. The diffuser suction component 74 descends and suctions a diffuser plate 121. Subsequently, the diffuser drive 73 lifts the suction component holding the diffuser plate 121 and moves it above the back panel 11, which is already in place and has completed top-side adhesive application. After precise positioning, the diffuser drive 73 controls the suction component to descend, smoothly placing the diffuser plate 121 in a pre-set position within the back panel 11. Finally, the suction component releases the diffuser plate 121 and resets, ready for the next loading cycle.

[0140] By setting up a diffuser adsorption component 74 driven by a diffuser drive component 73, and combining it with a dedicated diffuser storage component 72, this embodiment realizes the automatic picking, placing and transferring of the diffuser 121 from the storage position to the installation position of the back panel 11, replacing traditional manual operation, which helps to improve the automation level, accuracy and production cycle of this process.

[0141] In some examples, the diffuser drive 73 may include multiple drives to move the diffuser adsorption member 74 in different directions.

[0142] It should be noted that the structure of the optical film feeder is the same as that of the diffuser plate feeder 71. That is, the only difference between the optical film feeder and the diffuser plate feeder 71 is that the optical film feeder is used to adsorb and install the optical film 122, while the diffuser plate feeder 71 is used to adsorb and install the diffuser plate 121. Therefore, the optical film feeder will not be described here.

[0143] In some embodiments, see Figure 15 The diffuser plate loading machine 71 also includes a dust removal drive 711 and a dust removal unit 712. The dust removal drive 711 is installed on the diffuser plate bearing surface 721, and the dust removal drive unit is connected to the dust removal unit 712. The dust removal drive 711 is used to drive the dust removal unit 712 to move relative to the bearing surface, so that the dust removal unit 712 can remove dust from the diffuser plate 121 on the bearing surface.

[0144] Understandably, the dust removal drive unit 711 can be activated before the diffuser plate 121 is picked up and installed by the diffuser plate adsorption unit 74. This drives the dust removal unit 712 to move above or into contact with the surface of the diffuser plate 121, and cleans the surface of the diffuser plate 121 to be picked up on the bearing surface (especially the topmost plate). For example, dust, particles, or electrostatically adsorbed impurities that may adhere to the surface of the diffuser plate 121 can be removed by means of roller brush cleaning, ion air blowing, or dust roller rolling.

[0145] By providing a dust removal unit 712 driven by a dust removal drive 711 at the diffuser plate bearing surface 721, this embodiment achieves automatic cleaning of the diffuser plate 121 surface before loading. This helps reduce defects such as internal dirt or bright spots in the backlight module caused by impurities, improving product yield and optical quality.

[0146] In some examples, the dust removal drive 711 may include multiple drive members to drive the dust removal unit 712 adsorption member to move in different directions.

[0147] In some examples, the dust removal section 712 is, for example, a dust removal cloth or dust removal cotton.

[0148] The display screen mounting device 8 is described below: In some embodiments, see Figure 16 The display screen mounting device 8 includes a mounting drive component 81 and a display screen suction component 82. The display screen suction component 82 is connected to the mounting drive component 81, and the mounting drive component 81 is used to drive the display screen suction component 82 to move.

[0149] Understandably, the installation driver 81 first moves the display screen suction component 82 above the prepared display screen (e.g., a pre-applied LCD glass panel). The display screen suction component 82 descends and attaches to the display screen. Then, the installation driver 81 moves the suction component with the display screen attached to it above the back panel 11 with the backlight module already assembled. After precise alignment, the installation driver 81 controls the suction component to descend, smoothly covering the display screen onto the back panel 11, completing the installation. Finally, the suction component releases the vacuum, freeing the display screen and resetting.

[0150] By setting up a display screen adsorption component 82 driven by the installation drive component 81, this embodiment realizes the automation of the display screen handling and installation process, replacing the traditional manual handling and alignment operation, which is conducive to improving installation accuracy, protecting the fragile display screen, and improving the overall production cycle.

[0151] In some examples, the mounting drive 81 may include multiple drives to move the display magnetic component 82 in different directions.

[0152] In some embodiments, the display mounting device 8 further includes a display storage component for placing a display screen, and a separator is provided between two adjacent display screens. The automated production line for display devices also includes a control component. The mounting drive component 81 is electrically connected to the control component. The control component is configured to: control the mounting drive component 81 to move the display screen suction component 82 to the display screen storage component to pick up the display screen; control the mounting drive component 81 to move the display screen suction component 82 away from the storage component in a vertical direction; control the mounting drive component 81 to rotate the display screen suction component 82; and control the mounting drive component 81 to move the display screen suction component 82 to the back panel 11.

[0153] Understandably, firstly, the control installation drive 81 moves the display screen suction unit 82 above the display screen storage unit and aligns it with a display screen to be removed. The control installation drive 81 then lowers the display screen suction unit 82, allowing it to contact and firmly attach to the target display screen. Next, the control installation drive 81 moves the display screen suction unit 82, with the attached display screen, upwards vertically, moving it away from the storage unit and the lower divider. Immediately afterward, the control installation drive 81 rotates the display screen suction unit 82 (along with the attached display screen), for example, by rapidly rotating it around a horizontal or vertical axis at a certain angle or by vibrating it. Finally, the control installation drive 81 moves the rotated display screen suction unit 82, moving the display screen above the already positioned back panel 11 for precise alignment and installation.

[0154] Through the above control process, especially the step of "driving the display screen adsorption component 82 to rotate", centrifugal force or inertial force can be used to effectively peel off and shake off the separator that may be stuck to the surface of the display screen due to static electricity or slight adsorption. This avoids the risk of installing the separator along with the display screen into the back panel 11, and ensures the cleanliness and assembly quality of the final display module.

[0155] In some examples, the separator is typically a sheet of material with a certain thickness and rigidity, such as foam, plastic sheet, or release paper, to prevent the display surfaces from scratching or sticking together during storage and transportation.

[0156] The automatic screw-locking device 9 is described in detail below: In some embodiments, see Figure 17 and Figure 18 The automatic screw fastening device 9 is applied to the rear panel assembly 1 as described above. The automatic screw fastening device 9 includes a first screw fastening machine 91, which includes a first drive member 911, a first screw fastening member 912, and a first screw supply member 913. The first screw fastening member 912 is connected to the first drive member 911. The first drive member 911 is used to drive the first screw fastening member 912 to move so that the first screw fastening member 912 can connect the PCB board 13 and the rear panel 11 together with screws. The first screw supply member 913 is used to supply screws to the first screw fastening member 912.

[0157] Understandably, the back panel 11 and PCB board 13 are pre-positioned. The first drive unit 911 moves the first screw-locking component 912 to the outlet of the first screw supply component 913, where it picks up a screw. Then, the first drive unit 911 moves the first screw-locking component 912, carrying the screw, to the corresponding screw holes on the PCB board 13 and back panel 11. The first screw-locking component 912 performs a rotating and pressing action, screwing the screw into the screw hole, thereby fastening the PCB board 13 and back panel 11 together. The first screw supply component 913 continues to operate, supplying screws for the next fastening operation.

[0158] By incorporating a first screw-locking component 912 driven by a first driving component 911 and capable of acquiring screws from a first screw supply component 913, this embodiment automates the screw-locking operation. This replaces the traditional manual placement and tightening of screws, making the fixed connection between the PCB board 13 and the backplate 11 more efficient and consistent, thereby improving the automation level and production efficiency of this production process.

[0159] In some examples, the first drive member 911 may include multiple drive members to drive the first screw-locking member 912 to move in different directions.

[0160] In some embodiments, see Figure 19 and Figure 20 The automatic screw fastening device 9 also includes a second screw fastener 92, which includes a second drive member 921, a second screw fastening member 922, and a second screw supply member 923. The second screw fastening member 922 is connected to the second drive member 921. The second drive member 921 is used to drive the second screw fastening member 922 to move so that the second screw fastening member 922 can install screws into screw holes on the side wall of the rear panel 11. The second screw supply member 923 is used to supply screws to the second screw fastening member 922.

[0161] Understandably, after the back panel 11 is conveyed to the screw-locking station and positioned, the second drive unit 921 first moves the second screw-locking component 922 to the outlet of the second screw supply component 923 to obtain the screw. Then, the second drive unit 921 moves the second screw-locking component 922 carrying the screw to the side wall of the back panel 11, aligning the screw with the screw hole on the side wall. The second screw-locking component 922 performs a rotating and pressing action, screwing the screw into the screw hole on the side wall, completing the locking and fixing at that position.

[0162] By setting up a separate second screw fastener 92, this embodiment achieves automated screw fastening of the screw holes on the side wall of the back panel 11. This device can work in conjunction with the first screw fastener 91 or independently, expanding the scope of automatic screw fastening and further improving the automation coverage and production efficiency of the production line in the fastener assembly process.

[0163] In some examples, the screw supply can be a vibratory feeder.

[0164] In some examples, the second drive 921 may include multiple drive members to drive the second locking screw 922 to move in different directions.

[0165] In some embodiments, see Figure 19 and Figure 20 The automatic screw-locking device 9 also includes a rotary drive 93, which is connected to the second drive 921. The second screw-locking component 922 is connected to the rotary drive 93. The rotary drive 93 is used to drive the second screw-locking component 922 to rotate, so that the second screw-locking component 922 can switch between a state facing the second screw supply component 923 and a state facing the side wall of the rear panel 11.

[0166] Understandably, in actual operation, the second screw-locking component 922 needs to perform two main actions: retrieving the screw from the second screw supply component 923 and locking the screw into the screw hole on the side wall of the back plate 11. These two positions are often in different directions. Through the control of the rotary drive component 93, the second screw-locking component 922 can switch states during operation: when a screw needs to be retrieved, the rotary drive component 93 rotates the second screw-locking component 922 until its working end is directly opposite the outlet of the second screw supply component 923; when the screw has been retrieved and locking is required, the rotary drive component 93 again rotates the second screw-locking component 922, switching its working end to the state directly opposite the screw hole on the side wall of the back plate 11. After this or simultaneously, the second drive component 921 drives the entire assembly in a linear motion to complete the screw pickup or locking.

[0167] By incorporating a rotary drive component 93, this embodiment enables the second screw-locking component 922 to quickly switch between the material handling direction and the screw-locking direction. This design simplifies the complex motion trajectory required by the second drive component 921, allowing it to focus primarily on linear drive, while directional adjustment is handled by the dedicated rotary drive component 93, thus improving motion efficiency and positioning accuracy.

[0168] In some embodiments, the back panel 11 has a calibration point on its side wall, and the automatic screw fastening device 9 further includes a visual positioning module 94 and a control component, wherein the visual positioning module 94 is connected to the second drive member 921. Both the visual positioning module 94 and the second drive unit 921 are electrically connected to the control unit. The control unit is configured to: control the second drive unit 921 to drive the visual positioning module 94 to move; when the visual positioning module 94 detects a calibration point, acquire the current coordinates of the visual positioning module 94; determine the working coordinates of the second screw fastening component 922 based on the current coordinates; and control the second drive unit 921 to drive the second screw fastening component 922 to move based on the working coordinates.

[0169] Understandably, firstly, the second drive unit 921 is controlled to move the visual positioning module 94 to a general area where the side wall of the rear panel 11 can be observed.

[0170] Then, the visual positioning module 94 acquires and processes images of the side wall area to detect calibration points. When a calibration point is successfully identified, the control unit obtains the current coordinates of the visual positioning module 94 in the device coordinate system.

[0171] Next, the control unit calculates based on the acquired current coordinates and the positional relationship (i.e., coordinate offset) between the pre-calibrated calibration point and the target screw hole position, thereby determining the precise position required for the second screw fastening component 922 to perform the fastening operation, i.e., the operation coordinates.

[0172] Finally, based on the calculated working coordinates, the control unit generates control commands to drive the second drive unit 921 to move the second screw fastening unit 922 to the working coordinates and perform the screw fastening operation.

[0173] By setting up a vision positioning module 94 and a control component equipped with control logic, this embodiment achieves vision-based real-time positioning and compensation. This solution can effectively adapt to minor positioning deviations or manufacturing tolerances that may exist on the back panel 11 on the production line. By using a "vision positioning first, then calculation operation" approach, it guides the screw fastening component to accurately find the screw hole position, thereby improving the accuracy and reliability of the fastening operation.

[0174] In some examples, the calibration point can be a specific mark, hole, or contour feature whose location has a defined relative relationship to the screw holes to be fastened. The vision positioning module 94 typically includes an industrial camera and light source for acquiring images of the sidewall area of ​​the back panel 11. The control unit can be a programmable logic controller, an industrial computer, or a dedicated motion controller.

[0175] In addition to the structure described above, automated production lines for display devices may also include other components, which are described in detail below: In some embodiments, see Figure 21 , Figure 22 and Figure 23 The automated production line for display devices also includes a tooling plate assembly 110, which is connected to the conveyor 2. The tooling plate assembly 110 is used to support the back panel assembly 1, and the conveyor 2 is used to move the tooling plate assembly 110.

[0176] It is understood that the conveyor 2 is used to move the tooling plate assembly 110. When the conveyor 2 is running, its driving force acts on the tooling plate assembly 110 connected to it, thereby driving the tooling plate assembly 110 and the back panel assembly 1 carried on it to sequentially pass through each processing station along the predetermined path of the production line.

[0177] By setting up the tooling plate assembly 110 and connecting it to the conveyor 2 to support the back panel assembly 1, this embodiment provides a stable and reliable dedicated carrier for the transfer of the back panel assembly 1 on the production line. This changes the method of directly placing the back panel assembly 1 on the conveyor 2. Through the tooling plate assembly 110 as an intermediate carrier, not only is effective protection and precise positioning of the back panel assembly 1 achieved, but the interface between the conveyor 2 and the workpiece (back panel assembly 1) is also standardized, simplifying the production line design, improving the stability and repeatability of the conveying, and laying a solid foundation for subsequent automated assembly processes.

[0178] In some embodiments, see Figure 21 , Figure 22 and Figure 23 The tooling plate assembly 110 includes a tooling plate 1101 and a plurality of fixtures 1102. The fixtures 1102 are mounted on the tooling plate 1101, and the plurality of fixtures 1102 are arranged to form an installation space 1103. The installation space 1103 is used to install the back panel assembly 1.

[0179] Understandably, multiple jigs 1102 are arranged on the tooling plate 1101 to form an installation space 1103. Specifically, the distribution of these jigs 1102 matches the outer contour of the rear panel assembly 1, and they limit the rear panel assembly 1 from multiple sides or corners. The resulting installation space 1103 is adapted to the rear panel assembly 1 in terms of horizontal dimensions and shape.

[0180] The mounting space 1103 is used to install the back panel assembly 1. During operation, the operator or automatic feeding equipment places the back panel assembly 1 into the mounting space 1103. Due to the enclosure and restraint of multiple fixtures 1102, the back panel assembly 1 is precisely positioned and constrained in a preset position, and its degree of freedom of movement in the horizontal plane is effectively restricted, thereby achieving stable installation on the tooling plate 1101. Subsequently, the tooling plate assembly 110 is moved by the conveyor 2, and the back panel assembly 1 can be smoothly transported to each processing station.

[0181] By employing a structure in which multiple fixtures 1102 surround a tooling plate 1101 to form an installation space 1103, this embodiment provides a customized, high-precision positioning and bearing solution for the back panel assembly 1. This structure, through physical limiting, effectively prevents the back panel assembly 1 from shifting or swaying during dynamic processes such as conveying, lifting, and rotation, ensuring its positional consistency and stability throughout the entire process. This lays a solid foundation for the accurate execution of all subsequent precision assembly procedures.

[0182] In some embodiments, the fixture 1102 has a support surface, and the back panel assembly 1 abuts against the support surface.

[0183] Understandably, when the rear panel assembly 1 is installed in the mounting space 1103, the corresponding surface of its bottom or side will directly abut against the support surface. Specifically, when the rear panel assembly 1 is placed in the mounting space 1103 formed by a plurality of fixtures 1102, its own weight and the external forces it receives are transmitted to the support surface of the fixtures 1102 through the contact points.

[0184] During operation, the supporting surfaces of multiple fixtures 1102 work together to provide multiple distributed and stable support points for the rear panel assembly 1. Through the direct contact and bearing of these supporting surfaces, the rear panel assembly 1 is firmly lifted and held in a preset position within the installation space 1103, and its posture (especially its levelness) is maintained, avoiding deformation, displacement or stress concentration that may be caused by suspension or point contact.

[0185] By making the jig 1102 a supporting surface and having the back panel assembly 1 directly abut against it, this embodiment establishes a clear and reliable physical load-bearing relationship between the jig 1102 and the back panel assembly 1. This surface contact or adaptable contact method provides a stable distribution of supporting force, effectively ensuring the stability and flatness of the back panel assembly 1 on the tooling plate 1101, creating favorable conditions for the precise execution of subsequent processes.

[0186] In some embodiments, see Figure 21 , Figure 22 and Figure 23 The fixture 1102 includes a guide ramp 1104 and a limiting surface 1105 connected in sequence. The limiting surfaces 1105 of different fixtures 1102 surround and form an installation space 1103. The guide ramp 1104 can guide the rear panel assembly 1 so that the rear panel assembly 1 can move along the guide ramp 1104 into the installation space 1103.

[0187] Understandably, the guide ramp 1104 is a surface on the fixture 1102 with a certain angle of inclination. When the rear panel assembly 1 comes into contact with this ramp during installation, the guide ramp 1104 can guide it. Specifically, the inclined design of the ramp can gradually guide and correct any lateral offset or angular deviation that the rear panel assembly 1 may have, allowing it to move smoothly along the extension direction of the guide ramp 1104.

[0188] The limiting surface 1105 is a vertical or nearly vertical surface on the fixture 1102 that is connected to the guide ramp 1104 and is generally parallel to or matches the edge contour of the rear panel assembly 1. The limiting surfaces 1105 of multiple fixtures 1102 together enclose a mounting space 1103. The dimensions of the mounting space 1103 are closely fitted to the shape of the rear panel assembly 1 to ultimately accommodate and limit the rear panel assembly 1.

[0189] During operation, the operator or automated equipment places the back panel assembly 1 toward the area enclosed by the fixtures 1102. The edge of the back panel assembly 1 initially contacts the guide ramps 1104 of one or more fixtures 1102. As placement continues, the back panel assembly 1 automatically adjusts its position and angle under the guidance of the guide ramps 1104 and slides along the guide ramps 1104 until it is fully inserted into the mounting space 1103 defined by the limiting surfaces 1105 of the multiple fixtures 1102, achieving final precise positioning.

[0190] By configuring the jig 1102 to include a guide ramp 1104 and a limiting surface 1105 connected in sequence, this embodiment enables the jig 1102 to perform both guiding and positioning functions. The presence of the guide ramp 1104 greatly simplifies the placement operation of the back panel assembly 1, reduces the requirements for its initial placement accuracy, and reduces the risk of bumps caused by forced placement. Under the guidance, the back panel assembly 1 finally enters the installation space 1103 precisely formed by the limiting surface 1105, ensuring the accuracy and reliability of positioning. This structure is particularly conducive to achieving highly efficient and high-success-rate automated loading.

[0191] In some embodiments, see Figure 23 At least part of the fixture 1102 also includes a magnetic member 1106, which is disposed on the inner side wall of the fixture 1102 and is used to magnetically attract the top side of the back panel assembly 1.

[0192] Understandably, the magnetic clasp 1106 is located on the inner wall of the fixture 1102. Specifically, the magnetic clasp 1106 is embedded or fixed on the wall (i.e., the inner wall) of the fixture 1102 facing the mounting space 1103, and its position is configured to correspond to the top (upper) area of ​​the rear panel assembly 1 after it is installed in place.

[0193] The magnetic clasp 1106 is used to magnetically attach the top side of the back panel assembly 1. The magnetic clasp 1106 is typically a permanent magnet (such as a neodymium iron boron magnet) capable of generating a continuous magnetic field.

[0194] During operation, as the rear panel assembly 1 moves under the guidance of the guide ramp 1104 and is finally placed within the mounting space 1103 formed by the limiting surfaces 1105 of multiple fixtures 1102, the top-side metal portion of the rear panel assembly 1 (typically the edge of the metal rear panel) will approach or contact the magnetic attractor 1106 disposed on the inner wall of the corresponding fixture 1102. The magnetic field generated by the magnetic attractor 1106 will attract the top-side of the rear panel assembly 1, thereby applying a magnetic attraction force pointing towards the inner wall of the fixture 1102. This magnetic attraction force, combined with the mechanical limiting effect of the limiting surfaces 1105 of the fixtures 1102, together securely holds the rear panel assembly 1 in its mounting position.

[0195] By providing magnetic elements 1106 on at least part of the inner wall of the fixture 1102, this embodiment provides a non-contact, active adsorption fixation method for the back panel assembly 1 (particularly its top side). This method utilizes magnetic force to achieve automatic adhesion between the back panel assembly 1 and the fixture 1102, enhancing the connection reliability in the vertical direction and against slight vibrations or inertial forces. Compared to methods relying solely on gravity or friction, magnetic fixation is more proactive and effective, helping to further improve the positional stability of the back panel assembly 1 during dynamic transport and processing, while also having a simple structure and eliminating the need for complex mechanical locking actions.

[0196] In some embodiments, see Figure 23 The magnetic attractor 1106 includes a magnet, and a magnetic attractor groove 11021 is formed on the inner side wall of the fixture 1102, and the magnet is embedded in the magnetic attractor groove 11021.

[0197] Understandably, by embedding the magnet in the magnetic groove 11021 specially formed on the inner wall of the fixture 1102, this embodiment provides a stable and reliable magnet mounting solution. This structure ensures that the magnet is firmly confined in the predetermined position and is not easily loosened or dislodged due to vibration or external force, thereby ensuring the continuity and stability of its magnetic attraction to the back panel assembly 1. At the same time, the embedded installation also makes the magnet and the fixture 1102 form a whole, maintaining the flatness of the inner wall of the fixture 1102, which is conducive to the smooth insertion and positioning of the back panel assembly 1.

[0198] In some embodiments, see Figure 21 , Figure 22 and Figure 23 The tooling plate assembly 110 further includes at least a plurality of first mounting portions 1107 and a plurality of second mounting portions 1108, and the fixture 1102 can be mounted on any one of the first mounting portions 1107 and the second mounting portions 1108; The mounting space 1103 when the fixture 1102 is installed in the first mounting part 1107 is larger than the mounting space 1103 when the fixture 1102 is installed in the second mounting part 1108.

[0199] It is understandable that the mounting parts are usually threaded holes, positioning holes, T-slots or standardized fixture interfaces provided on the tooling plate 1101, which are distributed on the surface of the tooling plate 1101 in different layouts.

[0200] When the fixture 1102 is installed on the first mounting part 1107, the mounting space 1103 formed by the multiple fixtures 1102 based on the position of the first mounting part 1107 is larger than the mounting space 1103 formed when the fixture 1102 is installed on the second mounting part 1108. Specifically, the positional layout of the first mounting part 1107 makes the fixture 1102 closer to the edge of the tooling plate 1101 after installation, thereby creating a larger accommodating area; while the positional layout of the second mounting part 1108 makes the fixture 1102 closer to the center of the tooling plate 1101 after installation, thereby creating a smaller accommodating area.

[0201] During operation, when the production line needs to switch to produce rear panel assemblies 1 of different sizes, operators or automated tools can remove fixtures 1102 from the current set of mounting sections (e.g., the first mounting section 1107) and reinstall them on another set of mounting sections (e.g., the second mounting section 1108). This repositioning quickly changes the relative arrangement of all fixtures 1102 on the tooling plate 1101, creating a new mounting space that matches the size of the new model rear panel assembly 1. Subsequently, the new model rear panel assembly 1 can be securely mounted and positioned within this adjusted space for transfer and processing.

[0202] By providing multiple selectable mounting positions for the fixtures 1102 (first mounting part 1107 and second mounting part 1108) on the tooling plate 1101, this embodiment makes the layout of the key positioning structure of the tooling plate assembly 110—the fixtures 1102—adjustable. This design allows the same tooling plate assembly 110 to be remounted using simple fixture 1102 positions, quickly adapting to the load-bearing and positioning requirements of back panel assemblies 1 of different sizes and specifications. This significantly improves the flexibility of the production line and equipment utilization, reduces the tooling changeover time and the number of special fixtures required for product changes, and enhances production response speed and economy.

[0203] In some embodiments, see Figure 24 and Figure 25 The automated production line for display devices also includes a lifting device 120, which is used to lift the tooling plate assembly 110 so that the back panel assembly 1 rises and falls relative to the conveyor 2.

[0204] Understandably, after the tooling plate assembly 110 carrying the back panel assembly 1 moves to a specific station (such as a dispensing or light strip installation station) and is precisely positioned by the conveyor 2, the conveyor 2 pauses. At this time, the actuating part of the lifting device 120 rises, contacts the bottom of the tooling plate assembly 110, and smoothly lifts it, thus transforming the tooling plate assembly 110 and the back panel assembly 1 from a dynamic conveying state to a stable static support state. In this state, the influence of conveyor line vibration or unevenness on the back panel assembly 1 is eliminated, and the precise guiding and leveling mechanism of the lifting device 120 itself ensures that its back panel bearing surface is in a precise horizontal state. Subsequently, the processing equipment at this station (such as a dispensing head or a robotic arm) can perform high-precision operations on the back panel assembly 1 on this stable and horizontal reference surface, such as uniform dispensing or precision component assembly. After the operation at this station is completed, the lifting device 120 descends, smoothly sending the tooling plate assembly 110 and the back panel assembly 1 back to the conveyor 2, continuing to flow to the next process.

[0205] By setting up a tooling plate assembly 110 that cooperates with the conveyor 2 and adding a lifting device 120 at key workstations, this embodiment achieves reliable conversion and precise positioning of the back panel assembly 1 from continuous conveying to stable processing. Its core value lies in providing a highly stable and flat absolute horizontal working benchmark for all precision processing steps through lifting and active leveling. This effectively eliminates potential interference from the production line's transmission links on processing accuracy, thereby significantly ensuring the consistency of key process effects such as adhesive path quality and component assembly accuracy, and improving the quality and yield of the final product.

[0206] In some examples, the lifting device 120 is installed at the conveyor 2, which means that it is installed below the conveyor 2 and fixed horizontally. When the back panel assembly 1 moves above the lifting device 120, the lifting device 120 lifts the back panel assembly 1.

[0207] In some embodiments, see Figure 24 and Figure 25 The lifting device 120 includes a tooling plate lifting assembly 1201, which is connected to the tooling plate assembly 110. The tooling plate lifting assembly 1201 is used to drive the tooling plate assembly 110 to rise and fall relative to the conveyor 2.

[0208] Understandably, during operation, after the tooling plate assembly 110 carries the back panel assembly 1 and moves to the target workstation with the conveyor 2, the tooling plate lifting assembly 1201 is activated and produces a lifting action. Since this assembly is directly connected to the tooling plate assembly 110, its action directly acts on the tooling plate assembly 110, thereby smoothly and precisely raising or lowering the tooling plate assembly 110 and the entire back panel assembly 1 it carries, achieving a change in height relative to the conveyor 2. After lifting, the back panel assembly 1 is in a stable high position, facilitating precision operations; after the operation is completed, the tooling plate lifting assembly 1201 lowers it again, allowing it to re-engage with the conveyor 2 for continued circulation.

[0209] By setting up a tooling plate lifting assembly 1201 that is directly connected to the tooling plate assembly 110, this embodiment realizes direct drive and control of the lifting and lowering movement of the tooling plate assembly 110. This structural relationship is clear, and the power transmission is direct, which helps to ensure the smoothness of the lifting process and the accuracy of positioning, thereby providing a stable and reliable positioning foundation for the back panel assembly 1 at the processing station.

[0210] In some embodiments, see Figure 24 and Figure 25 The lifting device 120 also includes a lifting mounting frame 1202. The tooling plate lifting assembly 1201 includes a tooling plate lifting drive 1203. The tooling plate lifting drive 1203 is mounted on the lifting mounting frame 1202. The tooling plate lifting drive 1203 can be connected to the tooling plate assembly 110. The tooling plate lifting drive 1203 is used to lift the tooling plate assembly 110.

[0211] Understandably, the tooling plate lifting drive 1203 provides power to lift the tooling plate assembly 110. During operation, when the conveyor 2 moves the tooling plate assembly 110, which carries the back panel assembly 1, to the workstation and stops, the tooling plate lifting drive 1203 is activated. Its output end moves upward, and through its connection with the tooling plate assembly 110, it directly transmits the driving force to the tooling plate assembly 110, thereby overcoming gravity and other resistance, and lifting the tooling plate assembly 110 together with the back panel assembly 1 upward, causing it to detach from the conveyor 2 and be raised to the preset processing height.

[0212] By setting up the lifting mounting bracket 1202 and mounting the tooling plate lifting drive component 1203 on it, this embodiment provides a stable support structure for the lifting action. This structure clarifies the installation reference and power transmission path of the power component, which helps to ensure the stability of the lifting drive component during operation, thereby ensuring the smoothness and accuracy of its lifting action, and ultimately providing a reliable positioning guarantee for the precision machining of the rear panel assembly 1.

[0213] In some embodiments, see Figure 24 and Figure 25 The tooling plate lifting assembly 1201 also includes a first transition plate 1204. The tooling plate lifting drive 1203 connects the first transition plate 1204 and the lifting mounting frame 1202. The tooling plate lifting drive 1203 is used to drive the first transition plate 1204 to rise and fall relative to the lifting mounting frame 1202. The first transition plate 1204 has a first positioning block 1205 formed on the side opposite to the lifting mounting bracket 1202, and the tooling plate assembly 110 has a mating hole, and the first positioning block 1205 can be inserted into the mating hole.

[0214] Understandably, when the conveyor 2 moves the tooling plate assembly 110, which carries the back panel assembly 1, to the lifting position and stops, the tooling plate lifting drive 1203 first drives the first transition plate 1204 to rise. As the first transition plate 1204 rises, the first positioning block 1205 on it gradually approaches and finally precisely inserts into the mating hole at the bottom of the tooling plate assembly 110. Through the insertion and engagement of the first positioning block 1205 with the mating hole, the first transition plate 1204 and the tooling plate assembly 110 are precisely positioned horizontally and reliably mechanically connected. Afterward, the tooling plate lifting drive 1203 continues to operate, and through the connected first transition plate 1204, it can stably drive the entire tooling plate assembly 110 and the back panel assembly 1 to complete the subsequent lifting process.

[0215] By setting a first transition plate 1204 with a first positioning block 1205 and providing corresponding mating holes on the tooling plate assembly 110, this embodiment establishes a precise and reliable positioning and connection mechanism between the lifting drive component and the tooling plate assembly 110. This plug-in structure ensures the centering of power transmission and effectively prevents horizontal offset or swaying that may occur during the lifting process, thereby ensuring the positional accuracy and stability of the rear panel assembly 1 during lifting and high-position locking.

[0216] In some embodiments, the lifting mounting bracket 1202 is installed horizontally.

[0217] Understandably, by installing the lifting mounting bracket 1202 horizontally, a horizontal and stable installation and movement reference is provided for components such as the tooling plate lifting drive component 1203 and the first transition plate 1204 fixed thereon. During operation, this horizontal reference ensures that the lifting movement driven by the tooling plate lifting drive component 1203 can be carried out stably in the vertical direction or at a preset angle, reducing additional lateral forces or movement deviations that may be introduced due to the tilt of the installation foundation. This helps to ensure the accuracy and repeatability of the positioning state of the tooling plate assembly 110 and the back panel assembly 1 after the lifting process.

[0218] In some embodiments, see Figure 24 and Figure 25The lifting device 120 also includes a rear panel lifting assembly 1206, which is connected to the first transition plate 1204. The rear panel lifting assembly 1206 is configured to lift the rear panel assembly 1 after the tooling plate lifting assembly 1201 lifts the tooling plate assembly 110.

[0219] Understandably, during operation, the tooling plate lifting assembly 1201 (specifically, driven by the tooling plate lifting drive 1203, which in turn drives the first transition plate 1204) first lifts the tooling plate assembly 110, causing it, along with the supporting back panel assembly 1, to detach from the conveyor 2 and rise to a first height. Subsequently, the back panel lifting assembly 1206 activates, applying additional lifting force to the already lifted back panel assembly 1, causing it to rise further relative to the tooling plate assembly 110 (i.e., undergo a secondary lift), thereby reaching a higher second height or a height suitable for specific precision operations.

[0220] By adding a rear panel lifting assembly 1206 to the first transition plate 1204, this embodiment achieves graded or independent lifting of the rear panel assembly 1. This two-stage lifting mechanism allows for more precise height adjustment or the application of specific auxiliary support to the rear panel assembly 1 after the tooling plate assembly 110 has been stably lifted and positioned. This provides greater flexibility and operational space for subsequent precision adjustments or operations on the rear panel assembly 1 itself (such as local pressing, gap detection, etc.), which helps to further improve assembly accuracy and process adaptability.

[0221] In some embodiments, see Figure 24 and Figure 25 The rear panel lifting assembly 1206 includes a plurality of lifting columns 1207, which are connected to the side of the first transition plate 1204 away from the lifting mounting frame 1202. The tooling plate 1101 has a lifting hole 1109, and the lifting column 1207 can pass through the lifting hole 1109 to lift the back panel assembly 1.

[0222] Understandably, during operation, the tooling plate lifting assembly 1201 first drives the first transition plate 1204 to rise, thereby raising the tooling plate assembly 110 as a whole. Once the tooling plate assembly 110 reaches the first height, if a secondary lifting of the back panel assembly 1 is required, multiple lifting columns 1207 (usually driven by another drive component independent of the tooling plate lifting drive component 1203, or rising synchronously with the first transition plate 1204) move upwards relative to the first transition plate 1204. Since the lifting columns 1207 are connected to the first transition plate 1204, when they move upwards, the column passes through the corresponding lifting hole 1109 on the tooling plate 1101, extends from below the tooling plate 1101, and directly contacts and supports the back panel assembly 1 located above the tooling plate 1101, thereby lifting it upwards relative to the tooling plate 1101, achieving independent secondary lifting.

[0223] By setting multiple lifting columns 1207 passing through the tooling plate 1101, this embodiment provides a rear panel lifting solution with a direct structure and compact space. This design allows the lifting power source (located below the tooling plate 1101) to act directly on the rear panel assembly 1 through the holes in the tooling plate 1101 via the lifting columns 1207. This achieves independent and stable lifting of the rear panel assembly 1 without requiring complex modifications to the tooling plate 1101 itself, providing effective support for the precision adjustment or auxiliary processing of the rear panel assembly 1.

[0224] In some embodiments, see Figure 26 The automated production line for display devices also includes a rotating device 130, which can drive the tooling plate assembly 110 to rotate relative to the conveyor 2.

[0225] Understandably, the rotating device 130 is positioned at a specific workstation where the working posture needs to be adjusted. The rotating device 130 can dock or connect with the tooling plate assembly 110 that moves to the workstation and provide driving force to drive the tooling plate assembly 110 (together with the back plate assembly 1 thereon) to rotate about an axis relative to the stationary conveyor 2.

[0226] During operation, the tooling plate assembly 110 carrying the back panel assembly 1 is transported to the rotary station and positioned by the conveyor 2. Subsequently, the rotating device 130 is activated, driving the tooling plate assembly 110 to rotate. This changes the spatial orientation of the back panel assembly 1 fixed on the tooling plate 1101; for example, it can be rotated 90 degrees from its initial "top-facing" position to a "left-facing" position. After rotation, the back panel assembly 1 is locked in the new orientation so that subsequent stations can perform specific operations from a better angle (such as installing components from the side, performing lateral inspection, or dispensing adhesive). After the operation is completed, the rotating device 130 can drive the tooling plate assembly 110 back to its initial orientation or maintain the new orientation to flow to subsequent sections.

[0227] By incorporating the rotating device 130, this embodiment enables the production line to actively adjust the horizontal angle of the back panel assembly 1 during the flow process. This solves the problem that certain operations must be performed efficiently and accurately under specific orientations due to product structure or process requirements, thereby meeting the positioning needs of diversified and complex assembly processes and enhancing the process adaptability and flexibility of the production line.

[0228] In some embodiments, see Figure 26 The rotating device 130 includes a rotating mounting frame 1301 and a rotating component 1302. The rotating component 1302 is mounted on the rotating mounting frame 1301 and can be connected to the tooling plate assembly 110 to drive the tooling plate assembly 110 to rotate.

[0229] Understandably, the rotating component 1302 can connect with the tooling plate assembly 110 that has moved to the workstation. Specifically, the output end of the rotating component 1302 (e.g., a rotary platform, chuck, or drive head) is configured to dock or lock with the corresponding structure of the tooling plate assembly 110.

[0230] During operation, after the conveyor 2 moves the tooling plate assembly 110 and its supporting back panel assembly 1 to the rotary station and positions it, the rotating component 1302 starts. Through its connection with the tooling plate assembly 110, the rotating component 1302 outputs torque, directly driving the tooling plate assembly 110 (along with its back panel assembly 1) to rotate around a predetermined axis, thereby changing the horizontal orientation of its back panel assembly 1. After completing the required orientation adjustment, the rotating component 1302 can stop and maintain its position, or be driven to rotate as needed.

[0231] By setting up a rotating mounting bracket 1301 and mounting the rotating component 1302 on it, this embodiment provides a stable and reliable execution basis for the rotation action. This structure clarifies the installation reference and power output path of the drive component, which helps to ensure the smoothness of the rotation drive process and the accuracy of the rotation angle, thereby meeting the process requirements of multi-directional operation of the back panel assembly 1 on the production line.

[0232] In some embodiments, see Figure 26 The rotating device 130 also includes a lifting member 1303 and a connecting plate 1304. The lifting member 1303 is mounted on the rotating mounting frame 1301 and connected to the connecting plate 1304. The rotating member 1302 is mounted on the connecting plate 1304. The lifting member 1303 is used to drive the connecting plate 1304 to rise and fall relative to the rotating mounting frame 1301.

[0233] Understandably, after the tooling plate assembly 110, carrying the back panel assembly 1, is conveyed to the rotary station, the lifting member 1303 is activated first. The lifting member 1303 provides driving force, causing the connecting plate 1304 connected to it and the rotating member 1302 fixed on the connecting plate 1304 to move up and down relative to the rotary mounting frame 1301. Through this up and down movement, the rotating member 1302 can be adjusted to a suitable height position to reliably dock with the tooling plate assembly 110 above. Once the rotating member 1302 is connected to the tooling plate assembly 110, the rotating member 1302 can be activated, driving the connected tooling plate assembly 110 to perform rotational operations.

[0234] By adding a lifting component 1303 and a connecting plate 1304, and mounting the rotating component 1302 on the connecting plate 1304, this embodiment enables the rotating component 1302 to have vertical position adjustment capability. Furthermore, by lifting the back panel assembly 1, the back panel assembly 1 can be detached from the conveyor 2, ensuring that the back panel assembly 1 is in a horizontal state. This facilitates precise processing of the back panel assembly 1 and avoids the influence of the conveyor 2 on the processing. This allows the rotating device 130 to more flexibly dock and connect with tooling plate assemblies 110 of different heights or in different states, ensuring the reliability of rotational power transmission and creating favorable conditions for the smooth execution of rotational actions.

[0235] In some embodiments, see Figure 26 The rotating component 1302 includes a rotary motor 1305 and a rotary gear 1306. The rotary motor 1305 is mounted on the connecting plate 1304, and the rotary gear 1306 is rotatably mounted on the connecting plate 1304. The rotary motor 1305 is connected to the rotary gear 1306, and the rotary motor 1305 is used to drive the rotary gear 1306 to rotate. The rotary gear 1306 can be connected to the tooling plate assembly 110.

[0236] It is understandable that the rotary motor 1305 is connected to the rotary gear 1306. Specifically, the output shaft of the rotary motor 1305 is coupled to the axle of the rotary gear 1306 through a coupling, a reducer, or directly, thereby transmitting the rotational power of the motor to the rotary gear 1306, enabling it to be driven to rotate.

[0237] The rotating gear 1306 can be connected to the tooling plate assembly 110. In one implementation, the bottom or side of the tooling plate assembly 110 may be provided with a rack or another driven gear that meshes with the rotating gear 1306. When the lifting member 1303 drives the connecting plate 1304 and the rotating member 1302 mounted thereon to rise, causing the rotating gear 1306 to mesh with the corresponding transmission structure on the tooling plate assembly 110, the rotary motor 1305 is started. The rotary motor 1305 drives the rotating gear 1306 to rotate, and through the meshing action of the gear with the transmission structure on the tooling plate assembly 110, the rotational motion is transmitted to the tooling plate assembly 110, thereby causing it to rotate together with the back panel assembly 1.

[0238] By employing a structure in which a rotary motor 1305 drives a rotary gear 1306, this embodiment provides a rotary drive scheme with direct power transmission and precise transmission ratio. This gear transmission method can provide a large torque and achieve smooth and controllable rotary motion, thereby reliably meeting the process requirements for precise orientation adjustment of the tooling plate assembly 110 and the back panel assembly 1 during production.

[0239] In some embodiments, see Figure 26 The rotating device 130 also includes a second transition plate 1307, and a rotating gear 1306 is located between the second transition plate 1307 and the connecting plate 1304. The rotating gear 1306 is connected to the second transition plate 1307 to drive the second transition plate 1307 to rotate. The second transition plate 1307 has a second positioning block 1308 formed on the side opposite to the rotating gear 1306, and the tooling plate assembly 110 has a second mating hole, and the second positioning block 1308 can be inserted into the second mating hole.

[0240] Understandably, during operation, the lifting component 1303 first lifts the connecting plate 1304, rotating component 1302, and second transition plate 1307 as a whole, causing the second positioning block 1308 on the second transition plate 1307 to precisely insert into the second mating hole of the tooling plate assembly 110. This insertion and mating achieves precise horizontal positioning and reliable connection between the second transition plate 1307 and the tooling plate assembly 110. Subsequently, the rotary motor 1305 is started, driving the rotary gear 1306 to rotate, thereby rotating the second transition plate 1307 connected to it. Since the second transition plate 1307 and the tooling plate assembly 110 are locked together through the second positioning block 1308 and the second mating hole, this rotational motion is directly and without slippage transmitted to the tooling plate assembly 110, thereby causing the back panel assembly 1 it carries to complete a precise angular rotation.

[0241] By setting a second transition plate 1307 and utilizing the insertion structure of the second positioning block 1308 and the second mating hole, this embodiment constructs a rigid, high-precision motion transmission and positioning interface between the rotary drive source and the tooling plate assembly 110. This structure effectively eliminates transmission backlash, ensures high repeatability of the rotation angle, and facilitates rapid docking and separation between the rotating device 130 and the tooling plate assembly 110, thereby improving the reliability and efficiency of the rotary station.

[0242] In some embodiments, see Figure 26 The lifting component 1303 includes a lifting bracket and a lifting motor 1309. The lifting bracket is fixedly installed on the rotating mounting frame 1301. The lifting motor 1309 is connected to the lifting bracket and is connected to the connecting plate 1304. The lifting motor 1309 is used to drive the connecting plate 1304 to rise and fall relative to the rotating mounting frame 1301.

[0243] It is understood that the lifting motor 1309 is connected to the connecting plate 1304, that is, its output shaft or actuator is directly or indirectly connected to the connecting plate 1304. The lifting motor 1309 is used to provide driving force to drive the connecting plate 1304 to move up and down relative to the rotating mounting bracket 1301.

[0244] During operation, when it is necessary to adjust the height of the rotating component 1302 and the second transition plate 1307 to align with the tooling plate assembly 110, the lifting motor 1309 is activated. Since the lifting motor 1309 is fixed to the lifting bracket, the power it generates acts on the connecting plate 1304 connected to it, thereby smoothly and precisely driving the connecting plate 1304, as well as the rotating component 1302 and the second transition plate 1307 mounted thereon, to rise or fall relative to the fixed rotating mounting frame 1301, thus achieving height adjustment.

[0245] The lifting component 1303 is constructed by setting up a lifting bracket and a lifting motor 1309 mounted on it. In this embodiment, a clear power source and a stable support structure are provided for the lifting movement of the connecting plate 1304. This structure ensures the stability and controllability of the lifting drive process, and lays an important structural foundation for realizing reliable docking and power transmission between the rotating device 130 and the tooling plate assembly 110.

[0246] In some embodiments, the rotating mounting bracket 1301 is placed horizontally.

[0247] Understandably, by placing the rotating mounting bracket 1301 horizontally, a horizontal and stable mounting and movement reference is provided for components such as the lifting bracket and lifting motor 1309 fixed on it. During operation, this horizontal reference ensures that the lifting movement of the connecting plate 1304 driven by the lifting component 1303 can be carried out stably in the vertical direction, and provides a flat reference plane for the rotating component 1302 to drive the tooling plate assembly 110 to rotate. This helps to ensure the overall movement accuracy of the rotating device 130 and the accuracy of the relative positions of each component, thereby ensuring the positioning accuracy and process effect of the back panel assembly 1 during rotation and subsequent operations.

[0248] In some embodiments, the automated production line for display devices further includes a rotating device 130 and a flipping device, wherein the rotating device is capable of rotating the tooling plate assembly relative to the conveyor. The flipping device is located above the rotating device and is used to flip the tooling plate assembly.

[0249] Understandably, the rotating device 130 is positioned at the workstation where the horizontal orientation needs to be adjusted. It can dock with the tooling plate assembly 110 that has been moved there and generate a drive, thereby causing the tooling plate assembly 110 to rotate relative to the conveyor 2 about a vertical or approximately vertical axis, so as to change the horizontal orientation of the back panel assembly 1.

[0250] The flipping device is located above the station where the rotating device 130 is located. This flipping device is used to change the orientation of the tooling plate assembly 110 in the vertical plane after it has been horizontally rotated (or not rotated), that is, to flip the tooling plate assembly 110. For example, it can flip the tooling plate assembly 110 and its supporting back plate assembly 1 from a screen-up state to a screen-down state, or vice versa.

[0251] During operation, the tooling plate assembly 110 carrying the back panel assembly 1 is first conveyed to the composite workstation. The rotating device 130 can first drive the tooling plate assembly 110 to rotate to a specific angle. This operation can be used to adjust a specific side of the product (such as the side that needs to be inspected or operated) to the optimal direction facing the inspection equipment or operator, facilitating side inspection or operation. Subsequently, the upper flipping device is activated to perform a flipping action on the tooling plate assembly 110. This flipping can change the up-down orientation of the product, for example, flipping the product to a posture that facilitates bottom surface inspection or bottom operation. Through the coordinated or sequential operation of rotation and flipping, the back panel assembly 1 can ultimately be output in a standardized posture with the ground side facing the operator (or the reference direction of the next workstation) and the screen facing upwards, perfectly adapting to the stringent ergonomic and operational requirements of subsequent assembly, inspection, and other processes.

[0252] By integrating the rotating device 130 with the flipping device located above it at the same or adjacent workstations, this embodiment achieves continuous and precise adjustment of the horizontal orientation and vertical posture of the back panel assembly 1. This integrated design allows for multi-directional adjustments to be completed after a single positioning, which not only facilitates product inspection and operation from multiple angles but also ensures that the product enters subsequent production stages in a uniform and optimized posture (ground side facing the operator), greatly improving the automation level, operational convenience, and process standardization of the production line.

[0253] For example, in this embodiment, rotation is based on a vertical line as the axis of rotation, and flipping is based on a horizontal line as the axis of flipping.

[0254] In some embodiments, the flipping device includes a flipping lifting member and a clamping flipping member. The clamping flipping member is connected to the flipping lifting member. The flipping lifting member is used to drive the clamping flipping member to rise and fall relative to the tooling plate assembly 110. The clamping flipping member is used to clamp the tooling plate assembly 110 and flip the tooling plate assembly 110.

[0255] Understandably, the tilting and lifting mechanism provides the driving force to move the entire clamping and tilting component relative to the tooling plate assembly below. This tilting motion allows the clamping and tilting component to adjust its height to mate with the tooling plate assembly at different heights or positions.

[0256] The clamping and flipping component is used to perform clamping and flipping actions. During operation, after the flipping and lifting component lowers the clamping and flipping component to a suitable height, the clamping and flipping component activates its clamping mechanism (such as pneumatic grippers, mechanical calipers, etc.) to reliably clamp a specific part of the tooling plate assembly. Subsequently, driven by its internal flipping drive mechanism, the clamping and flipping component rotates around a horizontal or near-horizontal axis, thereby causing the tooling plate assembly (along with its back panel assembly) to complete the flipping action, realizing a change in its orientation (such as changing from screen-up to screen-down).

[0257] By configuring the flipping device as a separate structure consisting of a flipping lifting component and a clamping flipping component, this embodiment achieves the decoupling and synergy of the two functions of lifting positioning and clamping flipping. The flipping lifting component is responsible for precise height adjustment, ensuring reliable docking of the clamping action; the clamping flipping component is dedicated to clamping and rotation, ensuring the stability and controllability of the flipping process. This separate design enhances the flexibility and adaptability of the device, enabling it to more reliably complete the posture transformation task of tooling plate assemblies in the production line.

[0258] In some embodiments, the automated production line for the display device further includes a control module, which is configured to: control the rotating device 130 to rotate the tooling plate assembly 110 180° from its initial state; control the flipping device to flip the tooling plate assembly 110 so that the display screen of the back panel assembly 1 faces downward; control the rotating device 130 to rotate the tooling plate assembly 110 180° so that the ground side of the back panel assembly 1 faces the operator; and control the flipping device to flip the tooling plate assembly 110 so that the display screen of the back panel assembly 1 faces upward; wherein, in the initial state, the display screen of the back panel assembly 1 faces upward and the ground side of the back panel assembly 1 faces the operator.

[0259] It is understood that the control module is electrically connected to the rotating device 130 and the flipping device, and is configured to execute the following coordinated control process to perform precise attitude changes on the tooling plate assembly 110 that carries the back panel assembly 1: Initial state: When the tooling plate assembly 110 carries the back panel assembly 1 into the workstation, it is in a preset initial state. In this state, the display screen of the back panel assembly 1 faces upwards, and its ground side faces the operator.

[0260] First rotation: The control module first controls the rotation device 130 to start, causing the tooling plate assembly 110 to rotate 180° from its initial state. This operation causes the orientation of the back panel assembly 1 to be horizontally reversed, and its ground side changes from facing away from the operator.

[0261] First flip: Subsequently, the control module activates the flipping device located above, causing the tooling plate assembly 110 to flip. This flip changes the orientation of the entire back panel assembly 1 from display-up to display-down. At this time, the back side (usually the outer side of the back panel) of the back panel assembly 1 is facing up, facilitating possible cleaning, inspection, or back-side operations.

[0262] Second rotation: Next, the control module controls the rotation device 130 to start again, causing the tooling plate assembly 110, which was already in the display screen facing down position, to rotate another 180°. This rotation changes the horizontal orientation of the back panel assembly 1 again, so that its ground side is facing the operator again.

[0263] Second flip: Finally, the control module restarts the flipping device, causing the tooling plate assembly 110 to perform a flipping operation. This flip restores the back panel assembly 1 from a display-down position to a display-up position.

[0264] By executing the fixed sequence of "rotate 180° - flip (under screen) - rotate 180° - flip (over screen)" defined by the control module, regardless of the initial orientation of the back panel assembly 1 entering the station (standardized by preset initial state), the final output is always adjusted to a standardized posture with the display screen facing upwards and the ground side stably facing the operator. This series of actions, especially the intermediate flipping to under screen step, provides an opportunity for a comprehensive inspection of the back of the display screen and the structure of the back panel assembly 1. The entire process is automated, ensuring that products flow into subsequent assembly or inspection stations in a uniform and optimized posture, significantly improving the standardization level, ergonomics, and process quality control capabilities of the production line.

[0265] It should be noted that the combination of lifting device, rotating device, rotating device and flipping device can be applied to any of the following workstations: back panel dispensing device 3, light strip feeding device 4, reflector feeding device 5, top side dispensing device 6, optical component feeding device 7, display screen mounting device 8 and automatic screw fastening device 9.

[0266] The manufacturing method of the display device is described in detail below: In some embodiments, a method for manufacturing a display device includes: Step S1: Move the back panel 11 to the back panel adhesive dispensing device 3.

[0267] Step S2: Apply adhesive to the two oppositely arranged inner sidewalls 111 of the back panel 11 and perform adhesive curing operation; For example, the dispensing location in step S2 is, for instance, Figure 2 The position indicated by the arrow with number 100.

[0268] Step S3: Install the light strip 150 and the reflector sheet to the back panel 11 in sequence; Figure 29 and Figure 31 The images show the reflector 140 mounted on the rear panel. Figure 31 The arrow marked with number 200 points to the installation location of light strip 150. In other words, refer to... Figure 29 and Figure 31 This allows you to clearly see the installation positions of the light strip 150 and the reflector 140.

[0269] Step S4: Apply adhesive to the top side of the back panel 11 at 160°. Figure 32 The text indicates the location of 160 on the side of the sky. In other words, refer to... Figure 32 This allows you to determine the dispensing location in step S4.

[0270] Step S5: Install the diffuser plate 121 and the optical film 122 onto the back plate 11 in sequence; Figure 32 The arrow marked with reference numeral 300 points to the mounting position of diffuser plate 121 and optical film 122. In other words, combined with... Figure 2 and Figure 32 This allows you to clearly see the specific installation positions of the diffuser plate 121 and the optical film 122.

[0271] Step S6: Curing the adhesive applied to the top side of the back panel 11.

[0272] Step S7: Apply adhesive to the edge of the back panel 11; Figure 32 The arrow marked 400 points to the dispensing location in step S7. In other words, refer to... Figure 32 This allows you to determine the specific dispensing location in step S7.

[0273] Step S8: Obtain the display screen from the display screen storage location and rotate or shake the display screen.

[0274] Step S9: Install the display screen onto the bezel 170 of the back panel 11; Figure 32 The middle pointer indicates the position of the border at 170. That is, refer to... Figure 32 This allows us to determine the installation location of the display screen in step S9.

[0275] Understandably, the back panel 11, which serves as the assembly base, is automatically transported and positioned at the back panel adhesive dispensing station. Using the back panel adhesive dispensing device 3, continuous strips of adhesive (adhesive portion) are applied at a preset height on the inner sidewalls 111 of the left and right side panels of the back panel 11. Subsequently, ultraviolet light or other curing methods can be used to partially or fully cure the adhesive, forming a resilient cushioning structure. This adhesive portion is located between the inner sidewall 111 and the side of the optical component 12 to be installed later. Compared to the manual application of anti-collision cotton to the inner sidewall 111 in related technologies, this adhesive dispensing operation is easier to automate, the process is simpler, and the cured adhesive strip effectively prevents the hard inner sidewall 111 from scratching or colliding with the optical component 12 during subsequent assembly and transportation.

[0276] The LED strip is automatically picked up by the LED strip feeding device 4 and installed at the designated position at the bottom of the back panel 11. Then, the reflector is automatically picked up by the reflector feeding device 5, pre-bent if necessary, and then installed into the back panel 11 with the LED strip already installed.

[0277] Using the top-side dispensing device 6, adhesive is dispensed into the groove or a specific position on the upper side (top side) of the back panel 11. This adhesive is used for subsequent load-bearing bonding of the diffuser plate 121 and the optical film 122. The diffuser plate 121 is automatically picked up by the diffuser plate loading machine 71 and installed into the back panel 11, so that its side contacts the adhesive portion formed on the top side. Subsequently, the optical film loading machine automatically picks up the multilayer optical films 122 (such as diffuser film and brightness enhancement film) and stacks them sequentially on top of the diffuser plate 121. The adhesive dispensed on the top side is cured by irradiation using a curing device (such as an ultraviolet lamp), so that it firmly bonds and supports the diffuser plate 121 and the optical film 122 assembly.

[0278] Using a display screen dispensing device, sealant (such as PUR adhesive) is applied to the bezel or back panel 11 corresponding to the bezel position of the LCD glass panel (display screen). A display screen is picked up from the display screen storage unit (where spacers are placed between adjacent displays) using the suction attachment of the display screen mounting device 8. During transport, the mounting drive 81 is controlled to rotate or shake the suction attachment holding the display screen. This step aims to use inertial force to shake off any spacers that may be stuck to the display screen surface due to static electricity or slight adhesion, preventing them from being carried into the final product. The display screen is then moved and precisely positioned above the back panel 11 of the assembled backlight module, and then lowered to close the cover, pressing the display screen bezel against the adhesive lines to ultimately form a sealed display module.

[0279] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
