[0013] Preferably, the working method of the feeding device suitable for the LED lamp bead processing production line is as follows:

[0014] The LED lamp beads to be fed are stored in the vibrating feeding tray. Through the internal feeding track, the LED lamp beads are vibrated to enter the discharge rack with the lamp beads facing downward and the pins facing upward. The micro-electric cylinder in the discharge rack drives the limit plate to limit the lamp beads according to the size specifications of the LED lamp beads to ensure that the lamp beads are arranged neatly in the discharge trough.

[0015] Next, the rotating motor in the feeder rack drives the rotating rack to rotate, and the servo electric cylinder located directly below the rotating rack controls the flip rack to move downward, so that the LED lamp bead pins in the discharge rack are inserted into the material trough of the material taking block.

[0019] 2. In the present invention, under the precise control of the micro-electric cylinder, it can be flexibly adjusted according to the size specifications of the LED lamp beads. When discharging, the micro-electric cylinders on the front and rear sides drive the limit plates to approach the surface of the lamp beads to limit the lamp beads in the discharging trough, thereby effectively ensuring the regularity of the LED lamp beads in the discharging rack. This not only makes the lamp beads more orderly during the discharging process, avoiding the chaotic arrangement and mutual collision of the lamp beads, but also provides a guarantee for the subsequent feeding assembly rotating inside the feeding rack to accurately and continuously take materials, thereby ensuring that the LED lamp beads can smoothly enter the pre-processing rack for size detection, appearance defect detection, light intensity detection, surface dust cleaning and other processing. Finally, by removing defective lamp beads, the feeding conveyor rack and the discharge rack are used to stably and orderly transport qualified LED lamp beads to the next production link, which greatly improves the efficiency and product quality of the entire production process, and reduces production failures and defective rates caused by irregular arrangement of lamp beads.

[0020] 3.

During the pretreatment process, the motor in the driving frame drives the transmission rack to rotate, and then drives the rotating gear and the material picking block to rotate, so that the clamped LED lamp beads can be fully subjected to size detection, appearance defect detection, light intensity detection, surface dust cleaning and other processing operations, greatly improving the processing efficiency and accuracy; through the setting of the above structure, not only the automation and continuity of the feeding process are realized, and the production efficiency is improved, but also through precise control and flexible operation, the accurate position and posture of the LED lamp beads in each link are guaranteed, and the need for manual intervention and operation errors are effectively reduced, thereby improving product quality and production stability, and providing a strong guarantee for the efficient operation of the LED lamp bead processing production line.

[0038] Specifically, the loading assembly includes a rotating frame 8 and a material picking frame 11. The rotating frame 8 is rotatably arranged inside the feeding frame 3. A rotating motor 9 is fixedly arranged on the right side of the feeding frame 3, and one end of the output shaft of the rotating motor 9 is fixedly connected to the inside of the rotating frame 8. A plurality of material picking frames 11 are movably arranged on the outer peripheral surface of the rotating frame 8, and the plurality of material picking frames 11 are distributed at equal angles about the central axis of the rotating frame 8. A plurality of servo electric cylinders 10 are also fixedly arranged inside the rotating frame 8, and a plurality of flip frames 25 are fixedly arranged on the driving ends of the plurality of servo electric cylinders 10. One side of the plurality of flip frames 25 is rotatably connected to one side of the material picking frame 11 through an electric rotating shaft.

[0040] It should be noted that positive and negative electrode interfaces are respectively provided on both sides of the two electrode clamps 17. After the LED lamp beads are fed into the discharge rack 6, the driving end of the servo electric cylinder 10 located directly below the rotating rack 8 controls the flip rack 25 to move downward until the pins of several LED lamp beads inside the discharge rack 6 are respectively inserted into the material trough 16 inside each material taking block 15, and the two pins of the LED lamp beads are clamped by the two electrode clamps 17 inside the material taking trough 16. Then, the output shaft of the rotating motor 9 is used to control the rotating rack 8 to rotate inside the feeding frame 3, so that the next group of material taking blocks 15 continue to clamp and feed the LED lamp beads inside the discharge rack 6, and when pre-processing the LED lamp beads, the transmission rack 13 is driven by the electrode inside the driving rack 12 to rotate, and the transmission rack 13 is used to drive several rotating gears 14 to rotate, so that the several LED lamp beads clamped on the material taking block 15 can rotate, which is convenient for pre-processing the LED lamp beads.

[0043] It should be noted that, through the multiple pretreatment chambers 18 set inside the pretreatment rack 7, each chamber has a specific function. When the rotating rack 8 rotates to the position of the pretreatment rack 7 with the LED lamp beads, the closing plates 19 on both sides of the opening can flexibly control the opening and closing of the chamber, providing relatively independent space for different pretreatment operations. The laser displacement sensor 20 can accurately measure the size of the LED lamp beads to ensure that the dimensional accuracy meets the requirements; the machine vision sensor 21 can carefully detect the appearance defects of the lamp beads and promptly discover surface flaws and other problems; the distributed photometer 22 is used to detect the light intensity of the lamp beads to ensure that their luminous performance meets the standards; the air blowing cleaning rack 23 can clean the surface of the lamp beads, remove dust and other impurities, and improve the quality of the lamp beads; for unqualified defective products, the defective discharging rack 24 can smoothly discharge them to the outside of the feeding rack 3 to ensure that the products entering the subsequent production links are qualified products, which largely realizes the integrated and automated operation of LED lamp beads from loading to pretreatment, greatly improves production efficiency and product quality, reduces manual intervention and error rate, and provides a strong guarantee for the high-quality production of LED lamp beads.

Then, the rotating frame 8 continues to rotate, and the next group of material taking blocks 15 are ready to clamp the lamp beads. During the pre-processing operation, the motor in the driving frame 12 drives the transmission rack 13 to rotate, driving the rotating gear 14 and the material taking block 15 to rotate, so that the clamped LED lamp beads rotate.

[0048] When the rotating rack 8 rotates with the LED lamp beads to the position of the pretreatment rack 7, the closing plates 19 on both sides of the opening of the pretreatment chamber 18 are opened, and the LED lamp beads enter different chambers in turn.

7. The feeding device suitable for an LED lamp bead processing production line according to claim 6, characterized in that: The working method of the feeding device suitable for the LED lamp bead processing production line is as follows: The LED lamp beads to be fed are stored in a vibrating loading tray (1), and through the feeding track (2) inside the vibrating loading tray, the LED lamp beads are caused to enter a discharge rack (6) with the lamp beads facing downward and the pins facing upward under the action of vibration. The micro-electric cylinder (26) in the discharge rack (6) drives the limiting plate (27) to limit the position of the lamp beads according to the size specifications of the LED lamp beads, thereby ensuring that the lamp beads are arranged neatly in the discharge trough. Next, the rotating motor (9) in the feeding frame (3) drives the rotating frame (8) to rotate, and the servo electric cylinder (10) located directly below the rotating frame (8) controls the flip frame (25) to move downward, so that the pins of the LED lamp beads in the discharge frame (6) are inserted into the material trough (16) of the material taking block (15), and the electrode clamping plate (17) in the material taking trough (16) clamps the pins of the lamp beads through the electric push rod. Then, the rotating frame (8) continues to rotate, and the next group of material taking blocks (15) are ready to clamp the lamp beads. During the pre-processing operation, the motor in the driving frame (12) drives the transmission rack (13) to rotate, driving the rotating gear (14) and the material taking block (15) to rotate, so that the clamped LED lamp beads rotate; When the rotating rack (8) with the LED lamp beads rotates to the position of the pre-processing rack (7), the closing plates (19) on both sides of the opening of the pre-processing chamber (18) are opened, and the LED lamp beads enter different chambers in turn. The laser displacement sensor (20) accurately measures the size of the lamp beads, the machine vision sensor (21) detects appearance defects, the distributed photometer (22) detects the light intensity, and the air blowing cleaning rack (23) cleans the surface of the lamp beads. Unqualified defective products are discharged to the outside of the feeding rack (3) through the defective product discharge rack (24), and qualified products are stably transported to the next production link through the feeding conveying rack (4) and the discharge rack (5), thereby realizing the automation, orderliness and high-quality operation of the LED lamp bead feeding process.
