It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0031] It should be noted that in this utility model, the first direction is... Figure 1 The X direction in the middle, the second direction is... Figure 1 The Y-direction in the middle.

[0032] like Figures 1 to 3 As shown, one embodiment of this utility model provides a three-color LED bead feeding mechanism, including a storage component 1 and a top component 2; the storage component 1 includes a rotary drive 11 and a storage component 12 installed at the output end of the rotary drive 11. The storage component 12 is provided with three flexible storage trays 121 arranged in a ring at intervals, and the three flexible storage trays 121 are respectively used to store red LED beads, green LED beads and blue LED beads; it can be understood that the rotary drive 11 includes, but is not limited to, a motor, a rotary cylinder, etc.; the three flexible storage trays 121 are arranged at intervals along the circumference of the output end of the rotary drive 11, and the flexible storage trays 121 can be made of silicone film, etc.

[0033] The top-feeding assembly 2 includes a lifting drive assembly 21 and a lifting member 22 installed at the output end of the lifting drive assembly 21. The lifting drive assembly 21 is used to drive the lifting member 22 to lift the flexible storage tray 121. Understandably, the lifting drive assembly 21 includes, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc.; the top-feeding assembly 2 is located below the storage member 12; the top of the lifting member 22 is flat, and the lifting member 22 will not puncture the flexible storage tray 121.

[0034] In this invention, the storage component 12 is provided with three flexible storage trays 121 arranged in a ring at intervals. The three flexible storage trays 121 are used to store red LED beads, green LED beads, and blue LED beads, respectively. The storage component 12 is installed at the output end of the rotary drive component 11, and the lifting component 22 is installed at the output end of the lifting drive assembly 21. The rotary drive component 11 can drive the flexible storage tray 121 to rotate directly above the lifting component 22 assembly. The lifting drive assembly 21 drives the lifting component 22 to partially lift the flexible storage tray 121 from the bottom. Thus, the lifting component 22 can lift a few LED beads in the flexible storage tray 121, which makes it easier for the external suction nozzle to pick up the LED beads on the flexible storage tray 121 one by one. This avoids the accident of unstable suction when the external suction nozzle picks up multiple LED beads that are piled up or messy together one by one, and ensures the stability of the external suction nozzle picking up LED beads from the flexible storage tray 121. Furthermore, the structure of this three-color LED bead feeding mechanism is simple and the manufacturing cost is low.

[0035] In one embodiment, such as Figure 3 As shown, the lifting drive assembly includes a first lifting drive component 211 and a second lifting drive component 212. The lifting component 212 includes a push pin 221 and a top plate 222 with an adsorption hole 2221. The top plate 222 is mounted on the output end of the first lifting drive component 211, the second lifting drive component 212 is mounted on the top plate 222, and the push pin 221 is mounted on the output end of the second lifting drive component 212. The adsorption hole 2221 is used to adsorb the flexible storage tray 121, and the push pin 221 is used to lift the flexible storage tray 121. It can be understood that the first lifting drive component 211 and the second lifting drive component 212 include, but are not limited to, pneumatic cylinders, hydraulic cylinders, linear motors, etc.

[0036] Specifically, the rotary drive 11 can drive the flexible storage tray 121 to rotate directly above the lifting component 22. The first lifting drive 211 drives the top plate 222 to lift a portion of the flexible storage tray 121 from the bottom. After the adsorption hole 2221 adsorbs a portion of the flexible storage tray 121, the second lifting drive 212 drives the ejector pin 221 to further lift the flexible storage tray 121 lifted by the top plate 222. Thus, the ejector pin 221 can lift a very small number or a single LED bead through the flexible storage tray 121, and the external suction nozzle can pick up the LED bead lifted by the ejector pin 221. Thus, the external suction nozzle can pick up a single LED bead from the flexible storage tray 121. In this embodiment, after the top plate 222 adsorbs the flexible storage tray 121 through the adsorption hole 2221, the ejector pin 221 then lifts the flexible storage tray 121. This avoids the accident of the flexible storage tray 121 losing tension when the ejector pin 221 directly lifts the flexible storage tray 121, extends the service life of the storage component 12, and also ensures that the ejector pin 221 can lift a single lamp bead through the flexible storage tray 121, further ensuring the stability of the external suction nozzle in sucking a single lamp bead from the flexible storage tray 121.

[0037] In one embodiment, such as Figure 3 As shown, the storage component 12 has three annularly spaced first through holes, and the flexible storage tray 121 includes a flexible membrane, which is installed in each of the first through holes. Understandably, the flexible membrane can be made of materials such as silicone, and the flexible membrane has a certain tension.

[0038] In one embodiment, such as Figure 1 and Figure 2 As shown, the tri-color LED bead feeding mechanism also includes a base 3, and the material storage component 1 also includes a first driving component 13, a second driving component 14, a first support plate 15, and a second support plate 16. The first support plate 15 is slidably mounted on the base 3 along a first direction, and the second support plate 16 is slidably mounted on the first support plate 15 along a second direction perpendicular to the first direction. The rotary driving component 11 is mounted on the second support plate 16. It can be understood that both the first driving component 13 and the second driving component 14 include pneumatic cylinders, hydraulic cylinders, lead screw and nut mechanisms, etc. The first support plate 15 can be slidably mounted on the base 3 through guide rail slider components, guide rod sliding sleeve components, etc., and the second support plate 16 can be slidably mounted on the first support plate 15 through guide rail slider components, guide rod sliding sleeve components, etc.

[0039] The first drive assembly 13 is mounted on the base 3 and connected to the first support plate 15, and the second drive assembly 14 is mounted on the first support plate 15 and connected to the second support plate 16. Understandably, the first drive assembly 13 can drive the first support plate 15 to move along a first direction, and the second drive assembly 14 can drive the second support plate 16 to move along a second direction. In this embodiment, the first drive assembly 13 and the second drive assembly 14 can adjust the position of the storage member 12 in the first and second directions, so that the lifting member 22 can lift different parts of the flexible storage tray 121, thereby allowing different parts of the flexible storage tray 121 to feed material to the external suction nozzle.

[0040] In one embodiment, such as Figure 1 As shown, the storage assembly 1 further includes a first guide rail mounted on the base 3 along the first direction and a first slider mounted on the first support plate 15. The first slider is slidably connected to the first guide rail. Understandably, during the process of the first drive assembly 13 driving the first support plate 15 to move along the first direction, the first support plate 15 slides on the first guide rail through the first slider, thereby ensuring the stability of the first support plate 15 moving along the first direction.

[0041] In one embodiment, such as Figure 2 As shown, the storage assembly 1 further includes a second guide rail mounted on the first support plate 15 along the second direction and a second slider mounted on the second support plate 16, the second slider being slidably connected to the second guide rail. Understandably, during the process of the second drive assembly 14 driving the second support plate 16 to move along the second direction, the second support plate 16 slides on the second guide rail via the second slider, thereby ensuring the stability of the second support plate 16 moving along the second direction.

[0042] like Figure 4 As shown, another embodiment of this utility model provides a three-color LED bead conveying device, including a material handling robot 4 and the aforementioned three-color LED bead feeding mechanism. The material handling robot 4 is used to remove red, green, or blue LED beads from the flexible storage tray 121. Understandably, the material handling robot 4 can remove LED beads one by one from the flexible storage tray 121. In this embodiment, the three-color LED bead conveying device has a compact structure, occupies little space, and has a high degree of automation.

[0043] In one embodiment, such as Figure 4 and Figure 5As shown, the material handling robot 4 includes a gantry frame 41, a material handling drive assembly 42, a suction nozzle assembly 43, and a carrier plate 44 slidably mounted on the gantry frame 41. The material handling drive assembly 42 is mounted on the gantry frame 41 and connected to the carrier plate 44. The suction nozzle assembly 43 is mounted on the carrier plate 44 and is used to pick up red, green, or blue LED beads from the flexible storage tray 121. It is understood that the material handling drive assembly 42 includes, but is not limited to, a lead screw and nut mechanism, a pneumatic cylinder, a hydraulic cylinder, etc., and the carrier plate 44 can be slidably mounted on the gantry frame 41 via a guide rail slider assembly, a guide rod sliding sleeve assembly, etc.

[0044] Specifically, the material transfer drive assembly 42 can drive the suction nozzle assembly 43 to move above the flexible storage tray 121 via the carrier plate 44. The suction nozzle assembly 43 can then pick up LED beads from the flexible storage tray 121, and the material transfer drive assembly 42 can also transfer the LED beads to the next workstation via the suction nozzle assembly 43. In this embodiment, the material transfer robot 4 has a simple structure and low manufacturing cost.

[0045] In one embodiment, such as Figure 5 and Figure 6 As shown, the material handling robot 4 also includes a suction nozzle drive 45 mounted on the carrier plate 44, and the suction nozzle assembly 43 is mounted on the output end of the suction nozzle drive 45. It can be understood that the suction nozzle drive 45 includes, but is not limited to, a linear motor, a pneumatic cylinder, and a hydraulic cylinder, and the suction nozzle drive 45 can drive the suction nozzle assembly 43 to move vertically.

[0046] Specifically, the material transfer drive assembly 42 can drive the suction nozzle assembly 43 to move above the flexible storage tray 121 via the carrier plate 44, and then the suction nozzle drive member 45 drives the suction nozzle assembly 43 to descend, so that the suction nozzle assembly 43 can pick up the lamp beads from the flexible storage tray 121.

[0047] In one embodiment, such as Figure 6 As shown, the suction nozzle assembly 43 includes an elastic element 431, a suction nozzle body 432, and a suction nozzle seat 433 with a second through hole mounted on the carrier plate 44. The suction nozzle body 432 is slidably mounted in the second through hole. The elastic element 431 is sleeved on the suction nozzle body 432, and its opposite ends are respectively connected to the suction nozzle seat 433 and the suction nozzle body 432. It can be understood that the elastic element 431 includes, but is not limited to, springs, etc., and the suction nozzle body 432 can move vertically in the second through hole.

[0048] Specifically, when the suction nozzle body 432 picks up the LED beads from the flexible storage tray 121, the suction nozzle body 432 will squeeze the LED beads. The suction nozzle body 432 moves in the second through hole and compresses the elastic element 431, so that the suction nozzle body 432 and the LED beads are in flexible contact, avoiding the accident of damaging the LED beads due to rigid contact between the suction nozzle body 432 and the LED beads, and ensuring the quality of the LED beads. When the suction nozzle body 432 separates from the flexible storage tray 121, the elastic element 431 will drive the elastic body to move down to the reset position.

[0049] In one embodiment, such as Figure 4 and Figure 5 As shown, the material handling robot 4 also includes a camera 46 mounted on the carrier plate 44. Understandably, the camera 46 can photograph the flexible storage tray 121 to determine which part of the flexible storage tray 121 contains LED beads. Then, in conjunction with the first drive assembly 13 and the second drive assembly 14, the portion of the flexible storage tray 121 containing LED beads is moved above the lifting member 22, thereby ensuring the efficiency and accuracy of the material handling robot 4 in picking up LED beads from the flexible storage tray 121.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
