In addition, the lack of online performance testing means that unqualified chips flow into the chip mounting process, increasing the cost of defective products. Furthermore, the poor continuity of the feeding process and the lack of smooth coordination between various links result in frequent material shortages or accumulations. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figure 1 and Figure 2 One embodiment provided by this utility model: a method for LED The two-in-one feeding mechanism for bulk LED chip mounting includes a machine base 1. A control panel 2 and a first motor 7 are mounted on the surface of the machine base 1. A central shaft 6 is mounted on the output end of the first motor 7. A rotating wheel 8 is provided on the outer wall of the central shaft 6. A first vacuum tube 9 is evenly arranged in a ring on the outer wall of the central shaft 6. Multiple electric push rods 27 are evenly arranged around the rotating wheel 8 and correspond one-to-one with the first vacuum tube 9. A vacuum suction cup 11 is provided at the lower end of each electric push rod 27. A second vacuum tube 10 is opened at the upper end of each electric push rod 27 and communicates with the inside of the vacuum suction cup 11. Multiple straightening turntables 12, reversing turntables 17, multiple test seats 19 and a feeding cylinder 21 are slidably connected below the vacuum suction cup 11. A protrusion 18 is integrally formed on the upper end of the reversing turntable 17. A pair of test electrodes 20 are mounted on the upper end of the test seat 19. Multiple claws 13 are evenly arranged on the surface of the straightening turntable 12. Multiple clamps 14 are installed on the inner end of each claw 13.

[0027] Specifically, the output of the first motor 7 drives the central shaft 6 to rotate the wheel 8. The vacuum pump controls the vacuum suction cup 11 to generate suction through the cooperation of the first vacuum port 9 and the second vacuum port 10. The electric push rod 27 then pushes the vacuum suction cup 11 to precisely grab the LED bead. The electric push rod 27 can adjust the position of the vacuum suction cup 11 to adapt to different working conditions. The straightening turntable 12 straightens the LED bead posture through the claws 13 and the clamps 14. The reversing turntable 17 adjusts the direction of the LED bead through the protrusions 18. The test seat 19 detects the LED bead performance through the test electrodes 20. Through the coordination of various components, the LED bead is automatically grabbed, straightened, reversed and tested, ensuring continuous and accurate material supply, reducing manual intervention and improving LED chip mounting efficiency and product quality.

[0028] Reference Figure 1 A vibratory feeder 4 is installed on the surface of the machine base 1. A hopper 3 is set at the upper end of the vibratory feeder 4. The vibratory feeder 4 is mechanically connected to a feeding rail 5.

[0029] Specifically, LED bulbs are fed into the vibratory feeder 4 via the hopper 3. The vibratory feeder 4 then transports the bulbs from the hopper 3 to the feeding rail 5 in an orderly manner through vibration, thereby achieving automated feeding of the bulbs, replacing manual sorting, ensuring continuous feeding, providing a stable material supply for subsequent gripping and processing, and improving overall feeding efficiency.

[0030] Reference Figure 1 and Figure 2 The straightening turntable 12, the reversing turntable 17, the test seat 19 and the feeding cylinder 21 are arranged sequentially on the surface of the machine base 1 and below the turntable 8 and on the side close to the feeding rail 5.

[0031] Specifically, after the LED beads are picked up by the vacuum suction cup 11 from the feeding rail 5, they go through a sequence of straightening, reversing, testing, straightening again, testing again, and finally being fed into the loading cylinder 21, forming a continuous processing flow. This not only shortens the conveying distance between each stage and reduces losses and jams during the conveying process, but also ensures precise connection between each stage and avoids process chaos. At the same time, in conjunction with the infrared sensor controlling the rotating wheel 8 to rotate and convey, the LED bead posture correction, direction adjustment, performance testing, and temporary storage loading are completed efficiently, providing LED beads with correct posture and qualified performance for the subsequent chip mounting process, improving material supply efficiency and LED bead qualification rate.

[0032] Reference Figure 2 A flexible hose is connected between the first vacuum port 9 and the vacuum suction cup 11 via a flange.

[0033] Specifically, the first vacuum port 9 is connected to the vacuum suction cup 11 via a flange and a hose. The flange connection ensures the sealing of the connection between the two, effectively preventing vacuum suction leakage and allowing the vacuum suction cup 11 to maintain stable suction to reliably grasp the LED beads. The hose has flexible and deformable characteristics, which can adapt to the position changes of the vacuum suction cup 11 when the rotating wheel 8 is rotated and the electric push rod 27 is adjusted. It does not restrict the movement of related components, ensuring that the process of grasping and conveying the LED beads is smooth and without jamming, avoiding damage to components due to the rigidity of the connection structure, further maintaining the continuity and stability of the feeding process, and improving the overall feeding efficiency.

[0034] Reference Figure 2 A third motor 16 is installed on the surface of the machine base 1. A synchronous belt is installed at the output end of the third motor 16. The lower end of the reversing turntable 17 is connected to the synchronous belt drive. A second motor 15 is installed at the lower end of each straightening turntable 12. The second motor 15 is installed on the surface of the machine base 1.

[0035] Specifically, the third motor 16 provides power to the reversing turntable 17 via a synchronous belt. The synchronous belt drive ensures the accuracy and stability of power transmission, making the reversing turntable 17 rotate at a uniform speed. This allows the upper protrusion 18 to precisely adjust the direction of the LED beads, avoiding misalignment of the beads due to transmission deviation and ensuring the accuracy of subsequent surface mount processes. Each straightening turntable 12 is equipped with a second motor 15 at its lower end. This one-to-one drive method allows each straightening turntable 12 to independently control its speed and start / stop. The adjustment or failure of a single turntable will not affect the operation of other turntables, reducing the probability of overall equipment downtime, ensuring continuous material supply, avoiding drive deviation caused by vibration, and allowing the straightening turntable 12 to rotate precisely. This provides LED beads with qualified posture for subsequent reversing and testing processes, improving the overall material supply accuracy and efficiency.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The surface of the machine base 1 is equipped with a feeding track 22 and is adjacent to the rotating wheel 8. The feeding track 22 is connected to the feeding cylinder 21 by mechanical transmission. Multiple vibrators 23 are installed at the lower end of the feeding track 22. A protective plate 24 is provided on the surface of the feeding track 22. Multiple sets of sensors 25 are provided on the surface of the feeding track 22. Multiple holes and slots corresponding to the shape of the sensors 25 are opened on the surface of the protective plate 24. Multiple guide grooves 26 are opened on the inner wall of the feeding track 22.

[0037] Specifically, the feeding cylinder 21 smoothly transports the LED beads that have undergone alignment, reversal, and testing to the feeding track 22, ensuring continuous transport of the beads from pre-processing to subsequent surface mount assembly, avoiding material interruptions in the intermediate stages. The vibrator 23 prevents the beads from accumulating and getting stuck in the track through vibration, ensuring smooth and uninterrupted transport. The protective plate 24 prevents the beads from falling off the track during transport. The sensor 25 accurately monitors the position and quantity of the beads, promptly detecting material interruptions or congestion for quick adjustments. The guide chute 26 guides the beads to arrange them in an orderly manner in a fixed direction, providing neatly positioned beads for subsequent surface mount assembly processes, reducing surface mount misalignment problems. The overall structure improves the stability, orderliness, and controllability of the bead transport, further ensuring supply efficiency and surface mount quality.

[0038] Reference Figure 5 and Figure 6 A subsequent processing module 28 is provided on one side of the machine base 1. A feeding feeder 29 is provided on the side of the subsequent processing module 28 and the machine base 1. Multiple connection holes 30 are provided on the surface of the machine base 1. The machine base 1 and the feeding feeder 29 are connected by threads through the connection holes 30.

[0039] Specifically, the subsequent processing module 28 is fixedly connected to the machine base 1 to avoid vibration displacement and ensure accurate conveying. The machine base 1 is threadedly connected to the feeding feeder 29 through multiple connection holes 30 on its surface, making the feeding feeder 29 detachable from the machine base 1 for easy pushing, distance adjustment, and disassembly and maintenance. After the LED beads are conveyed by the vibrator 23 and the guide chute 26 of the feeding track 22, they enter the feeding feeder 29. After receiving the qualified LED beads conveyed by the feeding track 22, the feeding feeder 29 uses its own mechanical transmission structure to coordinate with the feeding rhythm of the machine base 1. The LED chips are continuously and accurately fed to the subsequent processing module 28 for precise material supply, achieving seamless connection between material supply and processing. This ensures the stability and continuity of material feeding and prevents the LED chips from shifting or being interrupted during transport. The subsequent processing module 28 then receives the processed LED chips for subsequent surface mount technology (SMT) processing. If the feeding feeder 29 malfunctions, it can be disassembled through the connection hole 30, and the feeding rail 22 can directly supply material to the subsequent processing module 28, thereby reducing downtime, ensuring production continuity, and improving SMT efficiency and quality.

[0040] Working principle: When this utility model is working, firstly, loose LED beads are fed into the vibratory feeder 4 through the hopper 3. The vibratory feeder 4 conveys the beads to the feeding rail 5 in an orderly manner through vibration. Then, the output end of the first motor 7 is controlled by the rear external sensor to drive the central shaft 6 to make the rotating wheel 8 rotate intermittently. When the rotating wheel 8 rotates, it drives each vacuum suction cup 11 to pick up the beads from the feeding rail 5 in turn. When the vacuum suction cup 11 reaches the feeding rail 5, the infrared sensor stops the rotating wheel 8 and starts the vacuum pump inside the machine 1. The vacuum suction cup 11 is made to generate suction through the first vacuum port 9 and the second vacuum port 10 and the hose. Then, the electric push rod 27 pushes the vacuum suction cup 11 to pick up the beads, thereby realizing orderly feeding and continuous and precise grasping of the beads, ensuring the continuity of work and improving work efficiency.

[0041] After the LED beads are adsorbed, the infrared sensor controls the rotation of the rotating wheel 8. The LED beads then rotate with the wheel 8 to above the straightening turntable 12. The infrared sensor then stops the rotation. Next, the second motor 15 drives the straightening turntable 12 to rotate, using the claws 13 and clamps 14 on its surface to straighten the LED beads. The LED beads then move to the reversing turntable 17, where the third motor 16 drives the synchronous belt to rotate the reversing turntable 17. The protrusions 18 adjust the direction of the LED beads to achieve reversal. After this, the LED beads on the rotating wheel 8 reach the test seat 19, where the test electrodes 20 align them. After performance testing, and then straightening and testing again, the LED beads are sent into the feeding cylinder 21. The LED beads are then sent to the feeding track 22 through mechanical transmission. Vibration by the vibrator 23, combined with the guide chute 26, causes the LED beads to be transported in an orderly manner. The protective plate 24 and the sensor 25 monitor the status of the LED beads in real time and transport the LED beads to the feeding feeder 29. Straightening and reversing ensure the correct posture and direction of the LED beads. The test seat 19 can screen out unqualified products in advance. The vibration and monitoring structure of the feeding track 22 ensures stable transportation, reduces manual intervention, and improves the efficiency of chip mounting and product quality.

[0042] After receiving qualified LED beads from the feeding track 22, the feeding feeder 29 uses its own mechanical transmission structure, in coordination with the feeding rhythm of the machine 1, to continuously and accurately feed the LED beads to the subsequent processing module 28, achieving seamless connection between feeding and processing, ensuring the stability and continuity of feeding, and preventing the LED beads from shifting or being interrupted during transport. Then, the subsequent processing module 28 receives the processed LED beads for subsequent surface mount processing. If the feeding feeder 29 malfunctions, it can directly feed the subsequent processing module 28 through the feeding track 22, thereby reducing downtime, ensuring production continuity, and improving surface mount efficiency and quality.
