[0031] Working Principle: This utility model includes an installation platform 2, a curing chamber 17, a conveyor belt 5, and a U-shaped automatic baffle 9. The top surface of the installation platform 2 has an installation groove 4, and conveyor shafts 6 are symmetrically installed within the groove 4. Conveyor rollers 8 are fixedly installed on the conveyor shafts 6, and a conveyor belt 5 is sleeved between the two conveyor rollers 8. A fixed platform 3 is welded to the inner side of the conveyor belt 5 within the installation groove 4. A servo motor 16 is bolted to one side of the installation platform 2, and the output end of the servo motor 16 is keyed to one end of the conveyor shaft 6. The curing chamber 17 is welded to the top surface of the installation platform 2, and an installation plate 26 is bolted to the top surface of the inner cavity of the curing chamber 17. Several infrared curing lamps 27 are evenly installed on the installation plate 26. The two side walls of the curing chamber 17 are symmetrically... The device is equipped with an inlet / outlet 25. An electric push rod 13 is bolted to the center of the top surface of the curing chamber 17, and a lifting plate 18 is bolted to the output end of the electric push rod 13. Several connecting rods 10 are welded to both sides of the bottom surface of the lifting plate 18, and a U-shaped automatic baffle 9 is welded to the bottom end of each connecting rod 10. Guide slide rods 14 are symmetrically welded to the top surface of the curing chamber 17, and guide sleeves 12 are symmetrically welded to the lifting plate 18, with guide slide rods 14 fitted inside the guide sleeves 12. In use, the worker can place the LED workpiece to be encapsulated and cured on one side of the top surface of the conveyor belt 5, and then start the servo motor 16 via the control panel 19 to drive the conveyor shaft 6 to rotate. As the conveyor shaft 6 rotates, the conveyor belt 5 can move the placed LED. The workpiece moves through inlet / outlet 25 into the curing chamber 17. The worker continuously places multiple LED workpieces on the conveyor belt 5 until a suitable number of LEDs enter the curing chamber 17. At this point, the servo motor 16 stops working. Then, the control panel 19 activates the electric push rod 13 to lower the lifting plate 18 until the automatic baffle 9 blocks both inlets / outlets 25. The control panel 19 then activates the infrared curing lamp 27 to heat and fix the LED workpieces, completing the encapsulation process. Afterward, the electric push rod 13 pushes the lifting plate 18 and the automatic baffle 9 upward, and the servo motor 16 continues to operate. The worker continues to place workpieces to be processed on the conveyor belt 5, while the processed workpieces are moved out of the curing chamber with the conveyor belt 5. The curing chamber 17 is automatically fed and unloaded by conveyor belt 5 to guide plate 7, eliminating the need for manual unloading. This cycle repeats, achieving automatic feeding and unloading of LED-encapsulated and cured workpieces. This improves work efficiency and reduces the risk of worker injury, enhancing practicality. Additionally, this invention includes a dust collector 11 and a dehumidifier 15. The dust collector 11 is bolted to one side of the top surface of the curing chamber 17, and a circulating air inlet pipe 20 is connected to one end of the inner cavity of the dust collector 11. An air inlet hood 28 is connected to one end of the circulating air inlet pipe 20 within the inner cavity of the curing chamber 17. The dehumidifier 15 is bolted to the other side of the top surface of the curing chamber 17, and a circulating air outlet pipe 22 is connected to one end of the inner cavity of the dehumidifier 15.Furthermore, the circulating air outlet pipe 22 is located at one end of the inner cavity of the curing chamber 17 and is connected to an air outlet hood 34. A connecting air pipe 21 connects the inner cavity of the dust collector 11 and the inner cavity of the dehumidification chamber 15, and a circulating air pump 35 is installed on the connecting air pipe 21. The top and bottom surfaces of the dust collector 11 are symmetrically provided with mounting grooves 31. The top and bottom surfaces of the dust filter frame 29 are symmetrically welded with mounting plates 30, and the mounting plates 30 are embedded in the mounting grooves 31. The inner cavity of the dehumidification chamber 15 contains a placement basket 32, and the placement basket 32 ​​contains a desiccant 33. When the curing chamber 17 is working, the circulating air pump 35 works simultaneously, which can circulate the hot air in the curing chamber 17 through the air inlet hood 28. The hot air is drawn into the dust collector 11 through the circulating air intake pipe 20. The dust filter frame 29 intercepts and filters solid dust from the hot air. Then, the hot air is pumped into the dehumidification chamber 15, where the desiccant 33 adsorbs water vapor. The dehumidified hot air then re-enters the curing chamber 17, significantly reducing the impact of water vapor and dust during continuous curing operations. This further improves the curing quality of LED packaging and enhances practicality. Both the dust collector 11 and the dehumidification chamber 15 are connected on one side by hinges 23 and equipped with sealed doors 24, facilitating subsequent cleaning of the dust filter frame 29 and replacement of the desiccant 33, further enhancing practicality.
