Description

Technical Field

[0001] This utility model relates to the technical field of backlight module processing equipment, specifically to an assembly equipment with alignment function. Background Technology

[0002] Chinese Patent No. CN118753902A discloses a backlight module manufacturing device with a light guide plate feeding system, comprising: a worktable; a multi-dimensional adjustment feeding component for picking up and positioning the light guide plate connected to the top of the worktable; an adjustable position calibration component for detecting and adjusting the position of the light guide plate, a winding component for winding the release film, a peeling support component for peeling the light guide plate from the release film, a guide pressing component for guiding and positioning the release film, and a guide inclined plate for tilting the release film; the front end of the peeling support component is connected to the winding component. The worktable is connected to a flipping and picking component for flipping the light guide plate on the left side of the front end of the peeling support component. The flipping and picking component includes a flipping component, a buffer support component, and a negative pressure suction component. The flipping component and the buffer support component are fixedly connected. The flipping component is connected to the negative pressure suction component. The bottom right end of the negative pressure suction component is attached to the top of the buffer component. The adjustable position calibration component adjusts the position of the detection end according to the length of the light guide plate to achieve detection suitable for light guide plates of different lengths. However, in the actual backlight module manufacturing field, precise alignment is still required in the assembly steps of each component in order to effectively carry out the detection work in each process.

[0003] However, current solutions generally rely on robotic arms equipped with vision systems for real-time alignment adjustments. Taking the assembly of a mobile phone backlight module as an example, its production process involves the high-precision stacking of multiple components such as light guide plates and reflective sheets, optical films, LED light sources, and frames. Each step requires the robotic arm to detect and correct the position of the components. For example, the alignment of the light guide plate and LED strips needs to be controlled within ±0.1mm, the alignment deviation between optical film layers needs to be <0.2mm, and the narrow bezel design requires the overall alignment accuracy of the backlight module and the display screen to be ≤0.1mm. In traditional solutions, after each component is grasped, the robotic arm needs to identify preset marker points or edge features through a vision system, calculate the deviation between the actual position and the theoretical coordinates, and then drive the joints to perform position compensation. This successive adjustment mode has a significant efficiency bottleneck: after each completion... A single component grabbing operation by a robotic arm involves three stages: visual recognition, data processing, and motion adjustment. Each alignment takes approximately 8-12 seconds. For a production line with an annual output of tens of millions of units, the alignment process alone consumes over 27,000 hours annually. The repeated acceleration and deceleration of the robotic arm exacerbates wear on servo motors and transmission components, shortens equipment maintenance cycles by 30%, and increases downtime failure rates by 15%. The communication delay between visual inspection and mechanical execution (typically 20-50ms) is amplified in high-speed production lines, resulting in actual alignment accuracy fluctuations of ±0.03mm. This makes it difficult to meet the assembly requirements of ultra-narrow bezel (<1mm) backlight modules. In modern production lines aiming for thousands of units per hour, these issues lead to a 30%-40% decrease in overall assembly efficiency and a 25% increase in production costs. Especially in multi-station parallel operation scenarios, the alignment time of the robotic arm becomes a key bottleneck restricting production line throughput.

[0004] Based on this, the present invention designs an assembly device with alignment function to solve the above problems. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] In some embodiments, please refer to the accompanying drawings. Figures 1-5 An assembly device with alignment function includes a worktable 1, an X-axis linear guide 2, a first slider 3, a Y-axis linear guide 4, a second slider 5, a cylinder 6, and a suction cup 7. The X-axis linear guide 2 is symmetrically fixedly connected to the top surface of the worktable 1. The first slider 3 is slidably connected to the surface of the X-axis linear guide 2. The bottom surfaces of both ends of the housing of the Y-axis linear guide 4 are fixedly connected to the top surfaces of the two first sliders 3. The second slider 5 is slidably connected to the surface of the Y-axis linear guide 4. The housing of the cylinder 6 is fixedly connected to the side wall of the second slider 5. The housing of the suction cup 7 is fixedly connected to the extension and retraction mechanism of the cylinder 6. The suction cup 7 is positioned so that its working end faces downwards towards the worktable 1. A groove is provided on the top surface of the worktable 1. A conveyor belt 8 for conveying backlight module components is connected to the inner wall of the groove. A guide groove 9 parallel to the conveyor belt 8 is provided on the top surface of the worktable 1. A material plate 10 is slidably connected to the inner wall of the guide groove 9 through a threaded rod transmission mechanism. A square hollow alignment frame 11 is fixedly connected to the top surface of the material plate 10. A pushing component is installed inside the alignment frame 11. A symmetrical alignment clamp 13 is connected to the inner wall of the alignment frame 11. The two alignment clamps 13 are brought closer together by the pushing component.

[0026] The alignment frame 11 has a separate upper and lower structure, with the two parts connected by bolts, facilitating the installation and maintenance of the internal pushing components. The X-axis linear guide 2, Y-axis linear guide 4, suction cup 7, conveyor belt 8, cylinder 6, and threaded rod transmission mechanism are all existing technologies used in backlight module processing and will not be elaborated upon here. The threaded rod transmission mechanism includes a threaded sleeve, a threaded rod, and a motor. The threaded sleeve is fixed to one end of the side wall of the material plate 10. During use, any module board in the mobile phone backlight module assembly falls onto the conveyor belt 8 through the previous process. At this time, the X-axis linear guide 2 and Y-axis linear guide 4 are adjusted to receive and grip the module board, respectively. The material plate 10 is then connected by the threaded rod. The transmission mechanism slides within the guide groove 9, initially set to the extended state. When the surface of the conveyor belt 8 falls behind the module plate, the cylinder 6 drives the suction cup 7 to descend. The suction cup 7 adsorbs the backlight module component on the conveyor belt 8. Subsequently, the cylinder 6 retracts, and the suction cup 7 lifts the component. Then, the X-axis linear guide 2 and the Y-axis linear guide 4 cooperate to drive the suction cup 7 to move the component above the material plate 10. The cylinder 6 then descends, placing the component into the alignment frame 11. Subsequently, the component on the material plate 10 is reset and recycled back into the guide groove 9. During the process, the module plate on the surface of the conveyor belt 8 is repeatedly placed into the alignment frame 11, realizing the operation of placing and aligning simultaneously with the conveyor belt, without the need for additional control of other devices for alignment processing.

[0027] In some embodiments, such as Figures 1-4 As shown, in a preferred embodiment of this utility model, the inner wall of the alignment frame 11 is provided with a storage groove 12, and the inner wall of the alignment frame 11 is provided with rectangularly distributed sliding grooves 14. A moving block 15 is slidably connected to the inner wall of the sliding groove 14. Both ends of the alignment clamping plate 13 are fixedly connected to the ends of the moving block 15. This structure allows the relative movement of the two alignment clamping plates 13 to have a distance limiting effect, while also providing a smooth movement effect. A spring 16 is fixedly connected to the side wall of the moving block 15 and one end of the inner wall of the sliding groove 14. 14. All moving blocks 15 are convex. Three springs 16 are provided on the surface of the moving blocks 15, arranged in a triangular shape on the opposite surface of the convex moving blocks 15 and the slide groove 14, and away from the moving direction of the moving blocks 15. They can be used to automatically reset the moving blocks 15 after they are pushed out, for the next push. When the moving blocks 15 slide in the slide groove 14, the triangular springs 16 can provide a uniform reset force from different directions, preventing the moving blocks 15 from tilting or jamming due to uneven force, and ensuring the smoothness and reliability of the reset action.

[0028] In some embodiments, such as Figures 1-5As shown, in a preferred embodiment of this utility model, the pushing component includes a rotating shaft 20. A symmetrical rotating groove 19 is formed inside the alignment frame 11. The rotating shaft 20 is rotatably connected to the inner wall of the rotating groove 19. A symmetrical groove 17 is formed on the inner wall of the rotating groove 19, and the groove 17 communicates with the receiving groove 12. A cam 18 is fixedly connected to the outer surface of the rotating shaft 20, rotating on the inner wall of the groove 17. One end of the cam 18 is in contact with the alignment clamp 13. The length of the cam 18 is greater than the depth of the receiving groove 12. With this structure, when the rotating groove 19 is rotating, the cam 18 can rotate on the inner wall of the groove 17. The cam 18 is gourd-shaped, with the end away from the alignment clamp 13 located inside the groove 17. When the rotating groove 19 rotates, the alignment clamp 13 is pushed out of the receiving groove 12 by the other end of the cam 18, creating an effect where the two alignment clamps 13 are relatively close, causing them to fall into the alignment frame 11. The backlight module on the wall is pushed to center and align. An installation groove 21 is provided inside one end of the alignment frame 11. Both ends of the installation groove 21 are equipped with pulleys 24 that are fixedly connected to the surface of the rotating shaft 20. A belt 25 is connected between the outer surfaces of the two pulleys 24. A slot 22 is also provided inside the end of the alignment frame 11 near the installation groove 21. A motor 23 is fixedly connected to the inner wall of the slot 22. The output end of the motor 23 is fixedly connected to one of the rotating shafts 20. When the motor 23 is driven, the rotating shaft 20 can be rotated, thereby achieving the effect of pushing the alignment clamp 13. Since the alignment frame 11 is fixed to the surface of the material plate 10, after each component of the backlight module is picked up from the surface of the conveyor belt 8, it can be directly placed into the alignment frame 11. As the material plate 10 moves, the pushing component on the alignment frame 11 can perform alignment processing on the backlight module component without actively adjusting other parts of the device.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
