Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead packaging technology, specifically to an LED lamp bead packaging structure. Background Technology

[0002] With the rapid development of LED lighting technology, white LEDs have become the mainstream in the market due to their advantages such as high efficiency, energy saving, and long lifespan. The preparation of the encapsulation layer for white LEDs is a crucial step determining their luminous performance and stability. This typically involves mixing epoxy resin or silicone with yellow phosphor in a precise ratio, dispersing the mixture, and then applying the adhesive to the chip surface using a dispensing machine. However, existing processes have significant drawbacks, severely restricting production efficiency and product quality.

[0003] From a process flow perspective, the mixing and dispensing steps are independent and carried out in separate steps. Traditional mixing devices only complete the uniform dispersion of phosphor and colloid. The mixed adhesive solution must be transferred to the dispensing machine barrel before the operation can continue. This separate operation not only increases material transfer time and manual intervention, but also easily introduces impurities, affecting the consistency of packaging. Moreover, each piece of equipment needs to be debugged and controlled independently, resulting in a long production cycle and making it difficult to meet the needs of large-scale automated production.

[0004] Bubble formation is another persistent problem in encapsulation layer preparation. During the mixing process, the addition of phosphor, stirring of the agitator, and material transfer can all introduce air into the adhesive, forming bubbles. If these bubbles remain in the encapsulation layer during dispensing, they can lead to light scattering loss, reduced luminous efficiency, and even chip failure due to moisture penetration. While existing centrifugal degassing processes can partially solve the problem, they require additional centrifugal equipment, and the degassing process is time-consuming, increasing equipment investment and energy costs. At the same time, centrifugal force can easily cause secondary sedimentation of phosphor or separation of the adhesive, affecting the optical performance of the encapsulation.

[0005] In summary, existing LED chip packaging layer manufacturing processes face technical bottlenecks in terms of integration, efficiency, and bubble control. There is an urgent need to develop a high-efficiency packaging technology that integrates mixing, debubbling, and dispensing to break through the constraints on industrial development.

[0006] Therefore, we propose an LED chip packaging structure to solve the above problems. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] In view of the shortcomings of the prior art, this utility model provides an LED lamp bead packaging structure to solve the problems mentioned in the background art.

[0015] Preferably, the outer ring wall of the rotating plate is provided with toothed grooves, which are used to cooperate with gears.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a packaging structure for LED beads, which has the following advantages:

[0018] 1. Through its overall design, this utility model can bring the following benefits to the overall operation:

[0019] Significantly improves production efficiency: In traditional processes, mixing, dispensing, and degassing of fluorescent powder require multiple machines operating in separate steps, resulting in time-consuming and labor-intensive material transfers. Integrated dispensing devices combine mixing, degassing, and dispensing functions into one unit, reducing material transfer steps and equipment changeover time. For example, there is no need to transfer the mixed adhesive to the dispensing machine barrel, nor is separate centrifugal degassing required. Production cycle time can be significantly shortened, increasing capacity per unit time and effectively meeting the needs of large-scale production.

[0020] Improving product quality and consistency: The integrated design reduces the number of times materials are exposed to the external environment, lowers the risk of impurity contamination, and ensures the purity of the encapsulating adhesive. At the same time, the device can precisely control mixing, degassing, and dispensing parameters, such as stirring speed, degassing time, and dispensing volume, avoiding parameter fluctuations caused by manual intervention or equipment switching. Taking phosphor as an example, stable mixing conditions can achieve nanoscale uniform dispersion, effectively reducing the color temperature drift of LED beads, significantly improving the consistency of product optical performance, and effectively reducing the defect rate.

[0021] Simplified operation process and management difficulty: The originally complex operation process of multiple devices is simplified to the control of a single device. Operators do not need to operate multiple devices frequently, which reduces training costs and the risk of operational errors. At the same time, equipment management and maintenance are more centralized, and the efficiency of troubleshooting and repair is improved, which helps enterprises achieve more efficient production management.

[0022] 2. This utility model, through the design of the repulsion or magnetic attraction between the first and second electromagnets and the third electromagnet, allows for switching between two modes: stirring and de-aeration. This dual-operation design of the equipment offers the following advantages to the overall operation:

[0023] Reduce hardware costs and complexity: Traditional packaging equipment requires separate components such as stirring paddles and degassing motors to achieve different functions, resulting in complex structures and high costs; this design only relies on the magnetic interaction of the first, second and third electromagnets to switch between stirring and degassing modes, greatly reducing the number of mechanical transmission components and significantly reducing maintenance costs.

[0024] Improved space utilization: The fewer components make the equipment structure more compact, eliminating the need to reserve separate installation space for different functions. Compared to traditional equipment, this device effectively reduces the floor space required, making it particularly suitable for production workshops with limited space. In addition, the streamlined internal structure facilitates integration of the equipment into automated production lines, enabling more efficient assembly line operations and further enhancing the flexibility of production layout.

[0025] Achieving rapid and precise mode switching: The electromagnet controls the direction and intensity of the magnetic force through electrical signals, and can switch between stirring and de-bubbling modes within seconds. Compared with the operation of replacing parts or adjusting parameters in traditional equipment, the efficiency is increased several times. For example, after the phosphor is mixed, there is no need to stop the machine to disassemble. Simply change the power state of the electromagnet to start the de-bubbling program, which significantly shortens the production cycle and meets the production needs of rapid iteration in LED packaging.

[0037] Please refer to Figures 1 to 6 As shown:

[0038] An LED bead packaging structure includes a main frame 1, on which a component 2 to be packaged is placed. A sliding rail 3 is fixedly connected to the main frame 1. A support 4 is connected to the sliding rail 3 via a drive chain. A dispensing cylinder 5 is fixedly connected to the support 4. A filling tube A6 and a filling tube B7 are respectively fixedly connected through the dispensing cylinder 5. An auxiliary piece 8 is fixedly connected to the upper end face of the dispensing cylinder 5. A gear 9 is fixedly connected to the non-axial part of the auxiliary piece 8. Protruding balls A10 are fixedly connected at equal intervals on the bottom surface of the auxiliary piece 8. A rotating piece 11 is rotatably connected to the dispensing cylinder 5. Protruding balls B12 are fixedly connected at equal intervals on the upper end face of the rotating piece 11. The bottom surface of the rotating plate 11 is fixedly fitted with a first electromagnet 13 at equal intervals, and the bottom surface of the rotating plate 11 is fixedly fitted with a second electromagnet 14 at equal intervals. The first electromagnet 13 and the second electromagnet 14 are arranged alternately. The inner wall of the dispensing cylinder 5 is symmetrically fixedly connected with a support chamber 15. A spring 16 is fixedly connected inside the support chamber 15. A circular plate 17 is fixedly connected to the top surface of the spring 16. A third electromagnet 18 is fixedly fitted and fitted to the upper surface of the circular plate 17 at equal intervals. A guide post 19 is symmetrically fixedly connected to the bottom surface of the circular plate 17. A main rod 20 is fixedly connected to the center of the bottom surface of the circular plate 17. A disturbance plate 21 is sleeved and fixed on the main rod 20.

[0039] in:

[0040] The filling tube A6 is used to introduce epoxy resin or silicone into the dispensing cylinder 5; the filling tube B7 is used to introduce fluorescent powder into the dispensing cylinder 5.

[0041] Gear 9 is driven by a drive motor.

[0042] The convex ball A10 and the convex ball B12 are used together to achieve the up-and-down reciprocating vibration of the disc 17.

[0043] The outer ring wall of the rotating plate 11 has toothed grooves, which are used to cooperate with the gear 9.

[0044] When the first electromagnet 13 and the third electromagnet 18 are energized, they have the same magnetic poles and are in a state of mutual repulsion; when the second electromagnet 14 is energized, it has opposite magnetic poles to the third electromagnet 18 and is in a state of mutual attraction.

[0045] The disturbance plate 21 is used to move up and down to mix the material in the glue cylinder 5.

[0046] Working principle:

[0047] In the initial state: the first electromagnet 13, the second electromagnet 14, and the third electromagnet 18 are not energized, and the spring 16 is in a normal relaxed state.

[0048] When using white light adhesive, the material dispensing equipment introduces epoxy resin or silicone into the dispensing cylinder 5 through dispensing pipe A6 according to the process ratio requirements; and introduces fluorescent powder into the dispensing cylinder 5 through dispensing pipe B7. After the addition is complete, the third electromagnet 18 on the disc 17 and the first electromagnet 13 on the second electromagnet 14 are energized. At this time, it is known that the first electromagnet 13 and the third electromagnet 18 have the same magnetic poles after being energized and are in a repulsive state; the second electromagnet 14, after being energized, interacts with the third electromagnet. The magnetic poles of the first electromagnet 13 and the third electromagnet 18 are opposite and are in a state of attraction. At this time, the disc 17 will move downward with the main rod 20 due to the mutual repulsion between the first electromagnet 13 and the third electromagnet 18. During this process, the spring 16 in the support chamber 15 is compressed, and the guide post 19 is used to assist the stable movement of the disc 17. Furthermore, after the first electromagnet 13 is energized for several seconds, it is de-energized. At this time, the disc 17, which was originally moving downward indirectly under the action of magnetic repulsion, will be moved upward by the reset of the spring 16.

[0049] Furthermore, as mentioned above, intermittently energizing the first electromagnet 13 can cause the disc 17 to reciprocate up and down within the dispensing cylinder 5; during the movement of the disc 17, the disc 17 will carry the disturbance plate 21 through the main rod 20 to agitate and mix the adhesive in the dispensing cylinder 5.

[0050] Furthermore, after mixing is complete, the first electromagnet 13 is de-energized, and the second electromagnet 14 is energized. At this time, under the action of the magnetic poles, the third electromagnet 18 on the disc 17 will move upward and magnetically attract the second electromagnet 14. At this time, the rotating plate 11 and the disc 17 temporarily form a whole through the second electromagnet 14 and the third electromagnet 18. Then, the gear 9 is activated. With the assistance of the teeth on the outer ring wall of the rotating plate 11, the rotating plate 11 will be driven to rotate by the gear 9. During the rotation of the rotating plate 11, the convex ball B12 on the rotating plate 11 will interact with the convex ball A10 on the auxiliary plate 8, causing the whole composed of the rotating plate 11 and the disc 17 to vibrate, thereby eliminating the bubbles generated by the disturbance mixing.
