Detailed Implementation

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] See Figures 1-3 As shown, an automatic sorting and feeding device for an LED bead dispensing machine includes a housing 1 and a conveyor belt 2 disposed on the housing 1 for conveying LED beads. The feeding device also includes a sorting unit 3, a feeding unit 4, and a driving unit 5. The sorting unit 3 is disposed on the top of the housing 1 and located on one side of the conveyor belt 2. The sorting unit 3 includes a mounting plate 31, a rotating block 32 rotatably disposed on the mounting plate 31, a flipping adsorption plate 33 for receiving LED beads, and a top plate 34 rotatably disposed on the rotating block 32. The feeding unit 4 is disposed on the top of the housing 1 and located on one side of the sorting unit 3. The feeding unit 4 includes a feeding sliding adsorption plate 46 capable of automatically sorting the LED beads on the housing 1. The driving unit 5 is disposed on the mounting plate 31 and can drive the rotating block 32 to rotate and drive the feeding sliding adsorption plate 46 to slide in a linear state.

[0028] The flip-over adsorption plate 33 is preferably a vacuum adsorption plate, and a clearance groove is provided on the flip-over adsorption plate 33 for the top plate 34 to tilt. When it is necessary to transfer the LED beads conveyed on the feeding unit 4, the LED beads are located below the flip-over adsorption plate 33 under the conveying of the feeding unit 4. At this time, the flip-over adsorption plate 33 adsorbs the LED beads. After adsorption, the drive mechanism drives the rotating block 32 to rotate along the mounting plate 31. When the rotating block 32 rotates, it drives the flip-over adsorption plate 33 to rotate until the flip-over adsorption plate 33 is above the conveyor belt 2. Then the top plate 34 lifts up and tilts and lifts the LED beads adsorbed on the flip-over adsorption plate 33. In this state, the flip-over adsorption plate 33 stops adsorbing the LED beads, so that the LED beads can fall onto the conveyor belt 2 through the tilted top plate 34, realizing the transfer of LED beads. This ensures the stability of LED beads during the conveying process, avoids the instability error of manual operation and lifting device, and can automatically sort the LED beads to be transferred during feeding.

[0029] See Figure 3 and Figure 4 As shown, the sorting unit 3 also includes a docking plate 35, a telescopic cylinder 36, and an extension rod 37; there is a pair of docking plates 35, which are respectively installed on both sides of the rotating block 32, and the docking plates 35 are located below the flipping adsorption plate 33; the telescopic cylinder 36 is rotatably installed on the rotating block 32 and located on one side of the docking plate 35; the extension rod 37 is provided at the output end of the telescopic cylinder 36, and the extension rod 37 is rotatably connected to the top plate 34. When the extension rod 37 moves, it can drive the top plate 34 to tilt towards the conveyor belt 2.

[0030] When the flipping adsorption plate 33 flips over to the top of the conveyor belt 2, the telescopic cylinder 36 is activated, driving the extension rod 37 to slide. When the extension rod 37 slides, it can lift the top plate 34 that is rotatably mounted on the rotating block 32, causing it to tilt and drive the top plate 34 to be in an inclined state towards the conveyor belt 2.

[0031] See Figure 4 and Figure 5 As shown, the sorting unit 3 also includes a bearing rod 38 and an electric roller 39; the bearing rod 38 is set on the top plate 34 and located above the rotating block 32; the electric roller 39 is set on the bearing rod 38 and close to one side of the docking plate 35. When the top plate 34 is tilted, the electric roller 39 is located above the rotated flip adsorption plate 33, ready to receive the lamp beads released from the flip adsorption plate 33.

[0032] When the top plate 34 tilts, it can drive the bearing rod 38 and the electric roller 39 to tilt synchronously. At this time, the flip adsorption plate 33 stops adsorbing the lamp beads, and the electric roller 39 starts. When the electric roller 39 starts, it can roll the lamp beads that are located on the flip adsorption plate 33 toward the conveyor belt 2, so that the lamp beads fall stably onto the conveyor belt 2 under the conveying of the electric roller 39, preventing the lamp beads from falling freely onto the conveyor belt 2 and causing deviation.

[0033] See Figure 6 As shown, the drive unit 5 includes a first rotary driver 51, a rotating rod 52, a first gear 53, and a second gear 54. The first rotary driver 51 is mounted on the mounting plate 31 and is located away from the rotating block 32. The rotating rod 52 is rotatably mounted on the mounting plate 31 and is fixedly connected to the rotating block 32. The first gear 53 is located at the output end of the first rotary driver 51. The second gear 54 is located outside the rotating rod 52 and meshes with the first gear 53. When the first gear 53 rotates, it drives the meshed second gear 54 to rotate, thereby driving the rotating rod 52 to drive the rotating block 32 to rotate synchronously.

[0034] When it is necessary to drive the rotating block 32 to rotate, the first rotary driver 51 is started first, driving the first gear 53 to rotate. When the first gear 53 rotates, it rotates the meshing second gear 54. Since the second gear 54 is fixedly connected to the rotating rod 52 and the rotating block 32, the rotating block 32 can rotate synchronously with the second gear 54, thereby realizing the rotation of the rotating block 32.

[0035] See Figures 3-7 As shown, the feeding unit 4 includes a positioning rod 41, a sliding block 42, a contact rod 43, and a return spring 44. A sliding groove is provided on the mounting plate 31, and the sliding groove is in the shape of a cuboid. The positioning rod 41 is disposed in the sliding groove and is located above the rotating block 32. The sliding block 42 is slidably disposed in the sliding groove and is clearance-fitted with the positioning rod 41. The contact rod 43 is rotatably disposed on the sliding block 42 and is located away from the sliding groove. The return spring 44 is disposed on the positioning rod 41, one end of the return spring 44 is fixedly connected to the sliding groove, and the other end of the return spring 44 is fixedly connected to the sliding block 42. When the sliding block 42 slides toward the setting direction of the return spring 44, the return spring 44 is in a compressed state.

[0036] When the rotating block 32 rotates and drives the flipping adsorption plate 33 to rotate, the rotating block 32 can contact the contact rod 43 provided on the sliding block 42 in this state, and drive the sliding block 42 to move along the sliding groove. During the movement of the sliding block 42, the return spring 44 is compressed. When the rotating block 32 and the flipping adsorption plate 33 flip and are above the conveyor belt 2, the return spring 44 is released and pushes the sliding block 42 back to the initial position.

[0037] See Figure 7 As shown, the feeding unit 4 also includes a mounting frame 45 and a hinge rod 47; the mounting frame 45 is installed on the top of the housing 1 and has a pair, and the pair of mounting plates are symmetrically distributed around the center line of the conveyor belt 2 and located on one side of the sorting unit 3; the mounting frame 45 is provided with a displacement groove for the feeding sliding adsorption plate 46 to slide; one end of the hinge rod 47 is rotatably mounted on the contact rod 43, and the other end of the hinge rod 47 is rotatably connected to the feeding sliding adsorption plate 46, and when the hinge rod 47 moves, it can drive the feeding sliding adsorption plate 46 to move horizontally along the displacement groove.

[0038] The feeding sliding adsorption plate 46 is preferably a vacuum suction cup. Initially, the LED beads are located below the feeding sliding adsorption plate 46, and the plate has already effectively adsorbed them. As the rotating block 32 rotates, the sliding block 42, driven by the hinge rod 47, causes the feeding sliding adsorption plate 46 to move carrying the adsorbed LED beads. This continues until the LED beads are delivered to the area below the flipped adsorption plate 33 after it has flipped and reset. After the LED beads reach the area below the flipped adsorption plate 33, the feeding sliding adsorption plate 46 stops adsorbing them. At this point, the flipped adsorption plate 33 has reset and is in a ready-to-adsorb state. During this process, the reset spring 44 releases, driving the sliding block 42 to slide along the sliding groove to its initial position. During the reset of the sliding block 42, the hinge rod 47 drives the feeding sliding adsorption plate 46 to move, completing the reset of the sliding block 42 and preparing for the next adsorption action of the feeding sliding adsorption plate 46. This achieves an automated, continuous, and stable sorting and feeding process for the LED beads.

[0039] Working principle: The flipping adsorption plate 33 is preferably a vacuum adsorption plate, and a clearance groove is provided on the flipping adsorption plate 33 for the top plate 34 to tilt and be retracted after tilting. First, the first rotary driver 51 is started, driving the first gear 53 to rotate. The first gear 53 meshes with the second gear 54. Since the second gear 54 is fixedly connected to the rotating rod 52 and the rotating block 32, the rotating block 32 rotates synchronously with the second gear 54. When the flipping adsorption plate 33 flips above the conveyor belt 2, the telescopic cylinder 36 is activated, driving the extension rod 37 to slide. The sliding of the extension rod 37 causes the top plate 34, which is rotatably mounted on the rotating block 32, to tilt, and at the same time drives the bearing rod 38 and the electric roller 39 to tilt synchronously. At this time, the flipping adsorption plate 33 stops adsorbing the lamp beads, and the electric roller 39 is activated, pushing the lamp beads located on the flipping adsorption plate 33 to roll towards the conveyor belt 2, ensuring that the lamp beads fall stably onto the conveyor belt 2 and preventing deviation. During the rotation of the rotating block 32 and the rotation of the flipping adsorption plate 33, the rotating block 32 contacts the contact rod 43 on the sliding block 42, driving the sliding block 42 to move along the sliding groove, while simultaneously compressing the return spring 44. When the rotating block 32 and the flipping adsorption plate 33 flip over to above the conveyor belt 2, the return spring 44 releases energy, pushing the sliding block 42 back to its initial position. The loading sliding adsorption plate 46 is also preferably a vacuum suction cup. In the initial stage, the lamp beads are located below the loading sliding adsorption plate 46 and have been effectively adsorbed. As the rotating block 32 rotates, the sliding block 42, driven by the hinge rod 47, causes the loading sliding adsorption plate 46 to move carrying the adsorbed lamp beads until the lamp beads are delivered to the area below the flipping adsorption plate 33 after it has flipped and reset. After the lamp beads reach the area below the flipping adsorption plate 33, the loading sliding adsorption plate 46 stops adsorbing the lamp beads. At this time, the flipping adsorption plate 33 has completed its reset and is in a state of waiting for adsorption. The return spring 44 releases energy, driving the sliding block 42 to slide along the sliding groove to its initial position. During the reset process of the sliding block 42, the hinge rod 47 drives the feeding sliding adsorption plate 46 to move, preparing for the next adsorption action.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
