Description

Technical Field

[0001] This utility model mainly relates to the field of LED display processing technology, specifically to an LED display assembly device for quantum film bonding and positioning. Background Technology

[0002] An LED display is a flat-panel display device that uses light-emitting diodes (LEDs) as pixels to directly emit light. Each LED pixel combines to form text, images, or videos by adjusting its brightness and color. Unlike traditional LCD displays that rely on backlighting, LED displays are self-emissive, have high brightness, high contrast, wide viewing angles, and longer lifespans, and are widely used in outdoor advertising screens, information billboards, and high-end televisions.

[0003] In existing technologies, the bonding of quantum film for LED displays is mostly done manually by laying it flat. The positioning mainly relies on mechanical stops, which has limited accuracy and is prone to cumulative errors. During the bonding process, the quantum film is placed directly on the surface of the display screen, which easily generates a large number of air bubbles and wrinkles because air cannot be expelled smoothly, resulting in low product yield. The subsequent pressing process lacks an effective guiding mechanism, and the pressing block is prone to skew, resulting in uneven pressure distribution. This may cause the quantum film to shift, stretch, or even be damaged, making it impossible to guarantee the uniformity and firmness of the bonding interface, which seriously affects the final display quality and production efficiency of the LED display. Utility Model Content

[0004] This invention provides an LED display assembly device for quantum film bonding and positioning, in order to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A quantum film bonding and positioning LED display assembly device includes a base plate and a conveyor belt. A robotic arm is installed on one side of the top of the base plate, and a bonding component is provided at one end of the robotic arm. A gantry frame is fixedly installed on the top of the base plate on one side of the robotic arm, and a pressing component is provided on the inner top wall of the gantry frame. The pressing component is located above the conveyor belt. A control component is provided on the other side of the top of the base plate. Multiple adsorption plates are fixedly installed on the top of the conveyor belt.

[0006] Preferably, the bonding assembly includes a mounting frame, a servo motor, a threaded rod, a T-block, a first electric push rod, and an adsorption plate. The mounting frame is fixedly mounted at one end of the robotic arm, and the servo motor is fixedly mounted on one side of the mounting frame. The inner walls of the mounting frame are connected by a rotating shaft, and one end of the threaded rod is connected to the output shaft of the servo motor. T-blocks are threadedly connected to the outer sides of both ends of the threaded rod, and the bottom of the two T-blocks is fixedly mounted with a first electric push rod. Adsorption plates are fixedly mounted on the execution ends of the two first electric push rods.

[0007] Preferably, the mounting bracket has a photoelectric sensor generator fixedly mounted on the side away from the servo motor, and a connecting block is fixedly mounted on one side of the adsorption plate, with a photoelectric sensor receiver embedded inside the connecting block.

[0008] Preferably, the pressing assembly includes a second electric push rod and a pressing block. The second electric push rod is fixedly installed on the inner top wall of the gantry frame, and the pressing block is fixedly installed on the actuating end of the second electric push rod.

[0009] Preferably, the control component includes a control box, a PLC controller, and an encoder. The control box is fixedly installed on the other side of the top of the base plate, and the PLC controller is fixedly installed on the bottom wall inside the control box. The encoder is connected to the top of the PLC controller.

[0010] Preferably, both ends of the two T-blocks are connected to limit rods through mounting holes, and both ends of the two limit rods are fixedly connected to the inner walls on both sides of the mounting frame.

[0011] Preferably, guide grooves are provided on both sides of the gantry frame, and guide blocks are fixedly connected to both ends of the pressing block, with the two guide blocks disposed inside the guide grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the coordinated operation of the photoelectric sensor generator and the photoelectric sensor receiver, it is possible to determine whether the display screen has reached the predetermined bonding position and feed the signal back to the PLC controller in real time. The linkage action of the PLC controller robotic arm, servo motor and first electric push rod ensures that the bonding component can move directly above the display screen. The servo motor drives the two T-blocks to move towards or away from each other, so that the quantum film produces a controllable pre-bending deformation and executes the bonding trajectory of center first contact and gradual flattening on both sides. This effectively removes the air between the film layer and the surface of the display screen, fundamentally avoiding the defects such as bubbles and wrinkles that are easily generated by traditional flat bonding, and significantly improving the positioning accuracy and first-time bonding yield of quantum film bonding.

[0013] 2. The pressing block is driven to press steadily down along the guide groove by the second electric push rod on the gantry, applying uniform final pressure. The sliding fit between the guide block and the guide groove ensures the verticality and stability of the pressing process, avoiding film displacement or damage caused by uneven force.

The bonding component 4 includes a mounting frame 401, a servo motor 402, a threaded rod 403, a T-block 404, a first electric push rod 405, and an adsorption plate 406. The mounting frame 401 is fixedly mounted at one end of the robotic arm 3, and the servo motor 402 is fastened to one side of the mounting frame 401. The threaded rod 403 is fixed between the two side walls of the mounting frame 401 through a rotating shaft. One end of the threaded rod 403 is connected to the output shaft end of the servo motor 402, and the two ends of the threaded rod 403 are connected to each other. A T-shaped block 404 is threadedly connected to the outside. A first electric push rod 405 is vertically mounted on the bottom of the T-shaped block 404. An adsorption plate 406 is mounted on the actuating end of the first electric push rod 405. Limiting rods 12 are arranged parallel to each other on both sides of the threaded rod 403. The two ends of the limiting rods 12 are fixed to the inner side wall of the mounting frame 401. The two ends of the T-shaped block 404 are machined with mounting holes that mate with the limiting rods 12. A photoelectric sensor generator 9 is mounted on the side of the mounting frame 401 away from the servo motor 402. A connecting block 10 is mounted on the side of the adsorption plate 8. A photoelectric sensor receiver 11 is embedded inside the connecting block 10. The photoelectric sensor generator... The photoelectric sensor 9 and the photoelectric sensor receiver 11 are aligned along their optical axes to form a through-beam detection unit. A gantry frame 5 is fixedly installed on the top of the base plate 1 on one side of the robotic arm 3. A pressing assembly 6 is provided on the inner top wall of the gantry frame 5. The pressing assembly 6 includes a second electric push rod 601 and a pressing block 602. The second electric push rod 601 is fixed to the inner top wall of the gantry frame 5. The actuating end of the second electric push rod 5 is connected to the pressing block 602. The bottom surface of the pressing block 602 is an elastic pressing surface. Guide grooves 13 are provided on both sides of the gantry frame 5. Guide blocks 14 are installed at corresponding positions on both sides of the pressing block 602. The guide blocks 14 are embedded in the guide grooves 13. The conveyor belt 2 has multiple suction plates 8 fixed on its top surface. The suction plates 8 are used to firmly fix the display panel during the bonding and pressing process. The control component 7 on the other side of the top of the base plate 1 includes a control box 701, a PLC controller 702, and an encoder 703. The PLC controller 702 is electrically connected to the controller of the robotic arm 3, the driver of the servo motor 402, the first electric push rod 405, the second electric push rod 601, the photoelectric sensor receiver 11, and the motor of the conveyor belt 2 via cables. The signal line of the encoder 703 is connected to the built-in encoder of the servo motor 402.

[0019] The specific operation method of this utility model is as follows: The LED display screen fixed on the adsorption plate 8 is moved by the conveyor belt 2. When the display screen reaches the predetermined bonding position, that is, when the photoelectric sensor generator 9 and the photoelectric sensor receiver 11 are on the same vertical line, the photoelectric sensor receiver 11 detects the change in the light path signal and immediately transmits the signal to the PLC controller 702. The PLC controller 702 then commands the conveyor belt 2 to stop running and simultaneously starts the robotic arm 3 to position the entire bonding assembly 4 directly above the display screen. Subsequently, the PLC controller 702 controls the adsorption plate 406 to evacuate and adsorb the quantum film. According to the preset program, the encoder 703 controls the servo motor 402 to run, driving the threaded rod 403 to rotate, which drives the two T-blocks 404 to move towards the center along the guide of the limit rod 12, causing the quantum film to undergo pre-bending deformation. The first electric push rod 405 extends downward at its actuating end, pushing... Two adsorption plates 406 and a slightly arc-shaped quantum film descend synchronously, ensuring that the center of the quantum film contacts the central area of ​​the display screen surface first. Then, the servo motor 402 rotates in the opposite direction, and the T-shaped block 404 drives the adsorption plate 406 to move outward, gradually flattening the curvature of the quantum film so that its two ends are laid flat and adhered to the display screen surface in sequence, effectively avoiding the initial entrainment of air bubbles. After the adhesion is completed, the adsorption plate 406 releases the quantum film, the robotic arm 3 drives the adhesion component 4 to reset, and the conveyor belt 2 restarts, transporting the display screen with the quantum film attached to the pressing station. The second electric push rod 601 on the gantry 5 moves downward, driving the pressing block 602 to press down steadily along the guide groove 13, applying uniform pressure to the composite structure of the quantum film and the display screen, further eliminating residual air between layers, and ensuring that the film layer and the display screen surface achieve a firm bond without air bubbles or wrinkles.
