Description

Technical Field

[0001] This invention relates to the field of composite fluorescent packaging technology, specifically to a high-temperature resistant surface-mount LED composite fluorescent packaging device. Background Technology

[0002] High-temperature resistant surface-mount LED composite phosphor packaging refers to the manufacturing technology of using special high-temperature resistant packaging material systems such as heat-resistant epoxy resin, modified silicone or ceramic substrate as carrier, and physically mixing and coating two or more phosphors with different luminescent properties, combined with surface mount technology, to package LED chips into LED devices that can work stably for a long time at high ambient temperature and junction temperature and achieve specific spectral output.

[0003] In practical applications, traditional high-temperature resistant surface-mount LED composite phosphor encapsulation devices typically require storing the composite phosphor in a designated storage silo during the encapsulation process. During coating, the phosphor is dispensed from the container using a dispensing needle. However, when the phosphor is added and stored in the silo, the phosphor is prone to sedimentation, stratification, and agglomeration. Phosphor particles of different densities gradually settle and separate, resulting in unstable component ratios in the output phosphor. Furthermore, when the phosphor comes into contact with air, microbubbles can easily form inside, leading to localized missing adhesive and uneven phosphor layer thickness after coating onto the LED chip surface. After curing, issues such as adhesive bursting and pores may occur. Summary of the Invention

[0007] Preferably, a support rod is fixedly connected to the bottom surface of each support plate, and the end of each support rod away from the support plate is fixedly connected to the side of the workbench near the support plate.

[0008] Preferably, the gas pressure equalization mechanism includes a gas storage tank. Two gas outlet pipes are fixedly connected to the outer surface of the gas storage tank.

[0014] Preferably, the inner wall of the storage bin is threaded with a sealing cover, and the outer surface of the sealing cover is provided with anti-slip grooves arranged at equal intervals.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: First, this invention incorporates a mixing and defoaming mechanism. A servo motor drives the rotating shaft and frame to rotate as a whole, causing the stirring shaft to rotate along the gear ring while simultaneously rotating on its own axis. This, in turn, thoroughly stirs the composite fluorescent agent inside the storage silo via a stirring plate. A spiral conveyor then transports the fluorescent powder settled at the bottom of the silo to the top, achieving overall cyclic mixing of fluorescent powders of different densities. This effectively prevents fluorescent powder sedimentation and stratification, ensuring a stable component ratio in the output fluorescent adhesive. Simultaneously, a vacuum pump draws the storage silo into a negative pressure state, causing tiny air bubbles inside the mixed fluorescent adhesive to rise and burst under negative pressure. Combined with the stirring and pushing functions of the servo motor, this effectively removes air bubbles trapped within the material, achieving thorough defoaming of the composite fluorescent agent. This defoaming process prevents problems such as insufficient adhesive or uneven thickness caused by air bubbles in subsequent coating operations.

[0016] Secondly, this invention, by incorporating a gas pressure equalization mechanism, utilizes an air storage tank to store clean compressed air that has undergone drying and sterilization. When the defoaming process is completed inside the storage silo, and it is necessary to restore normal pressure to ensure normal dispensing of the adhesive, a pressure sensor inside the storage silo detects a negative pressure value, causing an electric push rod to move the sealing block downwards, opening the air intake channel of the air intake hood. The clean air from the air storage tank enters the storage silo sequentially through the air outlet pipe, air guide pipe, and air inlet. The conical air baffle and conical buffer pad can buffer and disperse the high-speed airflow entering the storage silo, preventing the airflow from directly impacting the liquid surface of the composite fluorescent adhesive, thus avoiding violent disturbance of the liquid surface and the generation of new [airflow]. Once the pressure sensor detects that the pressure inside the silo has returned to normal, the electric push rod drives the sealing block to reset and close the air inlet channel. This quickly and stably restores and adjusts the pressure inside the storage silo, ensuring stable pressure during the subsequent dispensing process. It prevents sudden changes in dispensing speed due to abnormal negative pressure inside the silo, while also improving the stability of the composite fluorescent agent and enhancing the precision and uniformity of the fluorescent adhesive coating. Furthermore, the height at which the sealing block descends via the electric push rod controls the flow area of ​​the air inlet channel, thereby precisely adjusting the air intake speed. Combined with the pressure sensor, this achieves closed-loop pressure regulation within the silo, further enhancing the stability and controllability of the pressure recovery process.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figure 1-7A high-temperature resistant surface-mount LED composite phosphor encapsulation device includes a workbench 1, a mixing and defoaming mechanism 2 and a gas leveling mechanism 3 above the workbench 1. The mixing and defoaming mechanism 2 includes two support plates 201, each support plate 201 having its side near the workbench 1 fixedly connected to the side of the workbench 1 near the support plate 201. A storage bin 203 is fixedly connected to the upper surface of the two support plates 201. A support frame 204 is fixedly connected to the upper surface of the storage bin 203. A servo motor 205 is fixedly connected to the inner top wall of the support frame 204. A rotating shaft 211 is fixedly connected to the output end of the servo motor 205. The outer surface of the rotating shaft 211 is rotatably connected to the inner wall of the storage bin 203. A sealed bearing 212 is fixedly connected to the top end of the rotating shaft 211. The outer ring of the sealed bearing 212 is connected to... The inner wall of the storage silo 203 is fixedly connected to a spiral conveyor plate 213, the outer surface of the rotating shaft 211 is fixedly connected to two rotating frames 210, the inner top wall of the storage silo 203 is fixedly connected to a gear ring 206, the outer surface of the gear ring 206 is meshed with three gears 207, the inner wall of each gear 207 is fixedly connected to a stirring shaft 208, the outer surface of each stirring shaft 208 is rotatably connected to the inner wall of the rotating frame 210, and the outer surface of each stirring shaft 208 is fixedly connected to several stirring plates 209. The outer surface of the storage silo 203 is fixedly connected to a vacuum pump 214, the power input end of the vacuum pump 214 passes through the storage silo 203 and extends into the interior of the storage silo 203. By setting the mixing and defoaming mechanism 2, the composite fluorescent agent in the device chamber can be mixed evenly and defoamed.

[0021] Each support plate 201 has a support rod 202 fixedly connected to its bottom surface. The end of each support rod 202 away from the support plate 201 is fixedly connected to the side of the workbench 1 near the support plate 201. By setting the support rod 202, auxiliary support is formed for the support plate 201 and the storage bin 203, sharing the force at the connection between the support plate 201 and the storage bin 203, and improving the stability of the overall installation structure of the storage bin 203.

[0022] The bottom surface of the workbench 1 is fixedly connected to four support legs 4, and the bottom end of each support leg 4 is fixedly connected to a base 5. The support legs 4 and the base 5 together support the overall weight of the workbench 1 and the components above it. The base 5 increases the contact area between the device and the placement plane, which can lower the overall center of gravity of the device.

[0023] The outer surface of the workbench 1 is hinged with two cabinet doors 6. Each cabinet door 6 is fixedly connected to a handle 7 on the side away from the workbench 1. The interior of the workbench 1 can form a closed storage space through the cabinet doors 6, which is convenient for storing tools, consumables and maintenance parts required for the packaging operation, and is easy for operators to access and use at any time. The handle 7 makes it easy to apply force to open the cabinet door 6.

[0024] A vacuum adsorption stage 9 is fixedly connected to the upper surface of the workbench 1, and a high-temperature curing chamber 8 is fixedly connected to the upper surface of the workbench 1. The vacuum adsorption stage 9 can quickly position and fix the placed LED substrate to avoid the LED substrate from shifting or misaligning during coating and transportation, and ensure the accuracy of the dispensing position. The coated LED device can be directly sent into the high-temperature curing chamber 8 to complete the curing and molding of the composite fluorescent adhesive layer.

[0025] A dispensing machine 10 is fixedly installed on the upper surface of the workbench 1. The end of the dispensing machine 10 away from the workbench 1 is fixedly connected to the bottom surface of the storage bin 203. The dispensing machine 10 can quantitatively export the mixed and defoamed composite fluorescent adhesive and accurately apply it to the designated position of the LED chip fixed on the vacuum adsorption stage 9 to meet the dispensing requirements of the encapsulation operation.

[0026] The inner wall of the storage bin 203 is threaded with a sealing cover 11. The outer surface of the sealing cover 11 is provided with anti-slip grooves 12 arranged at equal intervals. Operators can add composite fluorescent adhesive to the storage bin 203 by unscrewing the sealing cover 11. The anti-slip grooves 12 can increase the friction between the hand and the outer surface of the sealing cover 11 when rotating the sealing cover 11, avoid slipping during the twisting process, and facilitate disassembly and assembly.

[0027] The specific implementation method of this embodiment is as follows: In use, firstly, the LED chip substrate to be packaged is placed on the surface of the vacuum adsorption stage 9, and the vacuum adsorption stage 9 is started to complete the positioning and fixing of the substrate. Then, the sealing cover 11 is unscrewed, and the prepared composite fluorescent adhesive raw material is injected into the storage bin 203. After tightening the sealing cover 11, the device is started. First, the servo motor 205 is started, and the servo motor 205 drives the rotating shaft 211 to rotate. The rotating shaft 211 drives the rotating frame 210 to rotate synchronously. The rotating frame 210 drives the three stirring shafts 208 to revolve around the rotating shaft 211. During the revolution, the gear 207 meshes and rolls along the gear ring 206, thereby driving the stirring shaft 208 to rotate, so that the stirring plate 209 moves against the inside of the storage bin 203. The composite fluorescent adhesive is thoroughly stirred from multiple angles. Simultaneously, the rotating shaft 211 drives the spiral conveyor 213 to rotate, conveying the high-density fluorescent powder deposited at the bottom of the storage silo 203 upwards. This achieves overall vertical circulation mixing of the fluorescent adhesive, preventing fluorescent powder precipitation and ensuring component uniformity. While mixing, the vacuum pump 214 is activated, drawing the inside of the storage silo 203 to a negative pressure state. This causes the tiny air bubbles trapped inside the adhesive to expand, float, and burst in the micro-negative pressure environment. Combined with the stirring and pushing functions, the air bubbles trapped inside the material can be fully carried out, achieving thorough defoaming of the composite fluorescent agent. This avoids problems such as insufficient adhesive or uneven thickness caused by air bubbles in subsequent coating operations.

[0028] Example 2 Please see Figure 1-7 The gas pressure equalization mechanism 3 includes a gas storage tank 301. Two gas outlet pipes 303 are fixedly connected to the outer surface of the gas storage tank 301. A one-way valve 306 is fixedly connected to the outer surface of each gas outlet pipe 303. A guide pipe 304 is fixedly connected to the bottom end of each gas outlet pipe 303. The bottom end of each guide pipe 304 is fixedly connected to the upper surface of the storage silo 203. A pressure sensor 305 is fixedly installed on the inner wall of the storage silo 203. A fixing ring 310 is fixedly connected to the inner wall of each guide pipe 304. An air inlet hood 311 is fixedly connected to the inner wall of each fixing ring 310. Several air inlet holes 312 are opened on the outer surface of each air inlet hood 311. A sliding... A sealing block 313 is dynamically connected. The outer surface of each sealing block 313 is slidably connected to the inner wall of the air guide pipe 304. An electric push rod 314 is fixedly connected to the bottom surface of each sealing block 313. A fixing plate 315 is fixedly connected to the bottom end of each electric push rod 314. The outer surface of each fixing plate 315 is fixedly connected to the inner wall of the air guide pipe 304. Eight connecting posts 307 are fixedly connected to the bottom surface of each air guide pipe 304. A conical air baffle 308 is fixedly connected to the bottom end of each set of connecting posts 307. A conical buffer pad 309 is fixedly connected to the inner wall of each conical air baffle 308. By setting the gas equalization mechanism 3, the negative pressure effect in the device chamber can be quickly restored to stable use.

[0029] A stabilizing block 302 is fixedly connected to the outer surface of the gas storage tank 301. The bottom surface of the stabilizing block 302 is fixedly connected to the upper surface of the support frame 204. The gas storage tank 301 is fixed above the support frame 204 by the stabilizing block 302, without occupying the operating space on the surface of the workbench 1. At the same time, it can reduce the vibration amplitude of the gas storage tank 301 during operation.

[0030] The specific implementation method of this embodiment is as follows: In use, the prepared composite fluorescent adhesive raw material is first injected into the storage silo 203 to complete the mixing and defoaming process. After the mixing and defoaming process, the storage silo 203 is in a negative pressure state, which cannot meet the normal pressure discharge requirements of the dispensing machine 10. After the negative pressure defoaming is completed, the dispensing operation cannot be carried out directly. The pressure difference will destroy the dispensing accuracy and affect the stability of the composite fluorescent adhesive itself, causing adhesive splashing. At this time, the pressure sensor 305 detects the negative pressure value inside the storage silo 203. Then, the electric push rod 314 inside the two air guide pipes 304 is activated. The electric push rod 314 pushes the sealing block 313 to slide down along the inner wall of the air inlet cover 311, gradually opening the air inlet hole 312 channel blocked by the sealing block 313. The clean compressed air that has been pre-stored in the air tank 301 and has been dried and sterilized is introduced into the storage silo 203 through the air outlet pipe 303, the one-way valve 306 and the air guide pipe 304 under the action of the pressure difference. The high-speed airflow flows out. After the air guide pipe 304, it first contacts the conical air baffle 308 and the conical buffer pad 309, and evenly disperses and buffers the airflow around the conical surface to prevent the airflow from vertically impacting the liquid surface of the composite fluorescent adhesive and to prevent the liquid surface from violently disturbing and entraining new air bubbles. When the pressure sensor 305 detects that the internal pressure of the storage bin 203 has gradually recovered to the preset normal pressure range, the control module controls the electric push rod 314 to drive the sealing block 313 to reset upward, re-blocking the air intake channel of the air inlet 312 and stopping the replenishment of gas into the storage bin 203. This quickly and stably completes the restoration and adjustment of the internal pressure of the storage bin 203. At this time, the dispensing machine 10 can be started to perform dispensing operations to ensure that the discharge speed is stable and controllable. During the operation of the device, the flow area of ​​the air inlet 312 can be changed by adjusting the extension length of the electric push rod 314, thereby accurately controlling the air intake speed. Combined with the real-time detection of the pressure sensor 305, the closed-loop regulation of the internal pressure is realized, further improving the stability and controllability of the pressure recovery process.

[0031] The working principle of this invention is as follows: In use, the LED substrate to be packaged is first placed on the surface of the vacuum adsorption stage 9. The vacuum adsorption stage 9 is then activated to position and fix the substrate. Next, the sealing cap 11 is unscrewed, and the prepared composite fluorescent adhesive raw material is injected into the storage hopper 203. After tightening the sealing cap 11, the device is started. First, the servo motor 205 is activated, which drives the rotating shaft 211 to rotate. The rotating shaft 211 drives the rotating frame 210 to rotate synchronously. The rotating frame 210 drives three stirring shafts 208 to revolve around the rotating shaft 211. During the revolution, the gear 207 meshes and rolls along the gear ring 206, thereby causing the stirring shaft 208 to rotate, causing the stirring plate 209 to perform multiple stirring operations on the composite fluorescent adhesive material inside the storage hopper 203. The mixture is thoroughly stirred, and simultaneously, the rotating shaft 211 drives the spiral conveyor 213 to rotate, conveying the high-density phosphor powder deposited at the bottom of the storage silo 203 upwards. This achieves overall vertical circulation mixing of the fluorescent adhesive, preventing phosphor sedimentation and ensuring component uniformity. While mixing, the vacuum pump 214 is activated, drawing the storage silo 203 into a negative pressure state. This causes the tiny air bubbles trapped inside the adhesive to expand, rise, and burst in the slightly negative pressure environment. Combined with the stirring and pushing functions, this effectively removes the air bubbles trapped inside the material, achieving thorough defoaming of the composite fluorescent agent. This defoaming process prevents problems such as insufficient adhesive or uneven thickness caused by air bubbles in subsequent coating operations. The prepared composite fluorescent adhesive raw material is then injected into the storage silo. After the mixing and defoaming process is completed in silo 203, the silo is under negative pressure, which cannot meet the normal pressure discharge requirements of the dispensing machine 10. After the negative pressure defoaming is completed, dispensing operations cannot be carried out directly, as the pressure difference will damage the dispensing accuracy and affect the stability of the composite fluorescent agent adhesive, causing adhesive splashing. At this time, the pressure sensor 305 detects the negative pressure value inside the silo 203 and then activates the electric push rods 314 inside the two air guide pipes 304. The electric push rods 314 push the sealing block 313 to slide down along the inner wall of the air inlet hood 311, gradually opening the air inlet 312 channel blocked by the sealing block 313. The clean compressed air, which has been dried and sterilized and pre-stored in the air tank 301, passes through the air outlet pipe 303 and the one-way valve 312 in sequence under the action of the pressure difference. The airflow enters the storage silo 203 through the air inlet 312 via the air guide pipe 304 and the air inlet pipe 304. After exiting the air guide pipe 304, the high-speed airflow first contacts the conical air baffle 308 and the conical buffer pad 309, and then evenly disperses and buffers the airflow along the conical surface to prevent the airflow from vertically impacting the liquid surface of the composite fluorescent adhesive, thus preventing violent disturbance of the liquid surface and the re-entry of new air bubbles. When the pressure sensor 305 detects that the internal pressure of the storage silo 203 has gradually recovered to the preset normal pressure range, the control module controls the electric push rod 314 to drive the sealing block 313 to reset upward, re-blocking the air intake channel of the air inlet 312 and stopping the replenishment of gas into the storage silo 203. This quickly and stably completes the restoration and adjustment of the internal pressure of the storage silo 203. At this time, the dispensing machine 10 can be started to perform dispensing operations.To ensure a stable and controllable discharge speed, the flow area of ​​the air inlet 312 can be changed by adjusting the extension length of the electric push rod 314 during device operation, thereby precisely controlling the air intake speed. Combined with real-time detection by the pressure sensor 305, closed-loop regulation of the pressure inside the chamber is achieved, further improving the stability and controllability of the pressure recovery process.
