[0016] The motor model is 57BYG250H, the controller model is Siemens S7-200SMARTSR40, the material pump model is KCB-18.3, the electric telescopic poles one / two are DTZ300, and the fan model is CF-110.

[0017] The LED bead encapsulation adhesive coating production device includes: a processing table 1, a turntable 2, an L-shaped block 3 and an L-shaped block 4. A rotating shaft is rotatably mounted on the top of the processing table 1, the turntable 2 is mounted on the rotating shaft, and the L-shaped blocks 3 and 4 are fixedly mounted on the top of the processing table 1 around the turntable 2. The L-shaped block 3 is equipped with an adhesive application assembly, which includes a mounting block 5, an adhesive application head 6, an electric telescopic rod 7, an adhesive storage tank 8, a material pump 9, and a telescopic hose 10. The mounting block 5 is positioned between the top of the turntable 2 and the bottom of the L-shaped block 3. The adhesive application head 6 is mounted on the bottom of the mounting block 5. The electric telescopic rod 7 is mounted on the top of the L-shaped block 3. The output shaft of the electric telescopic rod 7 passes through the L-shaped block 3 and connects to the top of the mounting block 5. The output shaft of the telescopic rod 7 is slidably connected to the L-shaped block 3. The glue storage tank 8 is installed on one side of the outer wall of the L-shaped block 3. The material pump 9 is installed on the top of the L-shaped block 3. A material suction pipe is installed on the material pump 9's suction port. One end of the material suction pipe extends into the glue storage tank 8. A material discharge pipe is installed on the material pump 9's discharge port. One end of the material discharge pipe passes through the L-shaped block 3 and is connected to the top end of the telescopic hose 10. The bottom end of the telescopic hose 10 is connected to the glue application head 6.

[0018] The controller 20 sends a command to start the motor 21. The output shaft of the motor 21 drives the rotating shaft to rotate, which in turn drives the turntable 2 to rotate. When the clamping assembly 19 holding the lamp board is transferred to the glue application station below the L-shaped block 3, the controller 20 triggers the motor 21 to stop. The controller 20 simultaneously starts the material pump 9 and the electric telescopic rod 7. The material pump 9 draws encapsulating glue (such as silicone or epoxy resin) from the glue storage tank 8 through the extraction pipe and delivers it to the telescopic hose 10 through the discharge pipe. At the same time, the output shaft of the electric telescopic rod 7 extends downward, driving the mounting block 5 and the bottom glue application head 6 to move down to the preset height. The encapsulating glue is evenly applied to the surface of the lamp bead 23 through the glue application head 6. After the glue application is completed, the electric telescopic rod 7 drives the glue application head 6 to reset, and the material pump 9 stops working.

[0019] The L-shaped block 2 4 is equipped with a drying assembly, which includes a cover 11, an electric telescopic rod 2 12, a heating box 13, a fan 14, an exhaust pipe 15, a telescopic hose 2 16, a connecting pipe 17, and a heating pipe 18.

The output shaft of the electric telescopic rod 2 12 passes through the L-shaped block 2 4 and is connected to the top of the cover 11. The output shaft of the electric telescopic rod 2 12 is slidably connected to the L-shaped block 2 4.

[0021] The controller 20 restarts the motor 21, and the turntable 2 continues to rotate, transferring the coated lamp board to the drying station below the L-shaped block 4. The motor 21 stops positioning, and then the controller 20 starts the electric telescopic rod 12. Its output shaft drives the cover 11 to move down, so that the cover 11 covers the coated area of ​​the lamp board. At the same time, the fan 14 and the heating tube 18 are started. The heating tube 18 heats the air in the heating box 13, and the fan 14 sends the hot air into the heating box 13 through the exhaust pipe 15, and then through the connecting pipe 17 and the telescopic hose 16 to the cover 11 to achieve uniform drying of the encapsulating adhesive. After drying, all components are reset.

[0022] The top of the turntable 2 is provided with three clamping components 19. Each clamping component 19 consists of a base plate 191, two vertical blocks 192, two horizontal blocks 193, two pressure blocks 194, two protective pads 195, two adjusting bolts 196, and two limiting sliders 197. The base plate 191 is installed on the top of the turntable 2, and the two vertical blocks 192 are respectively arranged on both sides of the base plate 191 and are connected to the top of the turntable 2.

[0023] Two horizontal blocks 193 are respectively installed on the outer wall of the two vertical blocks 192 that are close to each other. Two protective pads 195 are respectively installed on the bottom of the two pressure blocks 194. Two adjusting bolts 196 are respectively threaded on the top of the two horizontal blocks 193. The bottom end of the adjusting bolt 196 extends to the bottom of the horizontal block 193 and connects to the top of the pressure block 194. A groove is opened on one side of the outer wall of the vertical block 192. The limiting slider 197 is installed on one side of the outer wall of the pressure block 194. One side of the limiting slider 197 extends into the groove and slides in the groove.

[0024] Place the workpiece to be processed on the base plate 191 and manually rotate the adjusting bolt 196. Since the adjusting bolt 196 is threadedly engaged with the horizontal block 193 and the pressure block 194 is slidably connected to the groove of the vertical block 192 through the limiting slider 197 (limiting the offset of the pressure block), the adjusting bolt 196 will drive the pressure block 194 to move vertically downward until the protective pad 195 is tightly attached to the surface of the lamp plate 22, thus completing the stable clamping of the lamp plate and preventing the lamp plate from shaking in subsequent processes.

[0025] A controller 20 is installed on the top of the processing table 1, and a motor 21 is installed on the bottom of the processing table 1. The output shaft of the motor 21 is fixedly connected to the rotating shaft.

The lamp board 22 is rigidly connected to both sides of the LED beads 23 by fixing blocks 24 and fixing screws 25. After installation, the vibration amplitude of the LED beads can be reduced. Compared with traditional snap-fit ​​connections, the failure rate of poor contact and LED beads falling off during use can be reduced.
