[0029] REFERENCE Figures 1-9This utility model provides a bulk material feeder, including a frame 1, a mounting plate 2, and a linear feeding mechanism 7. The mounting plate 2 is slidably connected to the frame 1 via a linear guide rail 3. The frame 1 is provided with a linear module, which is used to drive the mounting plate 2 to slide. The mounting plate 2 is provided with a feeding mechanism 4, a vibratory feeder mechanism 5, and a conveying mechanism 6. The linear feeding mechanism 7 includes a discharge device 71 and a vibrator 72. The discharge device 71 includes a base plate 711, a cover plate 714, and several track adjustment plates 712 arranged side by side on the base plate 711. A linear track 713 for conveying LED beads is formed between two adjacent track adjustment plates 712. The cover plate 714 covers the linear track 713, and the length of the cover plate 714 is less than the length of the linear track 713, so that the two ends of the linear track 713 are not covered by the cover plate 714, forming a feeding position and a mounting position.

[0030] Understandably, the staff places loose LED beads into the feeding mechanism 4, which then transports them to the vibratory feeder mechanism 5. The vibratory feeder mechanism 5 oriented and transports the LED beads, and the conveying mechanism 6 transports them to the linear feeding mechanism 7. Since the feeder 71 has multiple linear tracks 713, the mounting plate 2 is moved on the frame 1 by the linear module drive, allowing the conveying mechanism 6 to place the LED beads at the feeding position of each linear track 713. Under the action of the vibrator 72, the LED beads move to the mounting position of the linear track 713. In this way, the LED beads are arranged in a straight line at the mounting positions of multiple linear tracks 713, which makes it easier for the pick-and-place machine's linearly arranged nozzles 66 to grab the entire row of LED beads at once, achieving a more efficient LED bead picking speed and improving production efficiency.

[0031] In some embodiments, refer to Figure 3 and Figure 4 The cover plate 714 is made of glass. Several photoelectric sensors 73 are arranged side by side on the cover plate 714. The photoelectric sensors 73 are arranged one-to-one above the linear tracks 713 and are located in the middle section of the linear tracks 713. When LED beads are stored in the linear tracks 713, the photoelectric sensors 73 detect whether there are LED beads at that position. If not, it means that the linear track 713 does not store enough LED beads, and the conveying mechanism 6 will put more LED beads in the linear track 713.

[0032] In this embodiment, refer to Figure 5 and Figure 6The feeding mechanism 4 includes a support frame 41, a funnel 42 mounted on the support frame 41, a vibrating screen bucket, and a feeding hopper sluice 43. The vibrating screen bucket is connected between the funnel 42 and the feeding hopper sluice 43. The feeding hopper sluice 43 includes a first sluice 431 and a second sluice 432 arranged in opposite directions. The first sluice 431 is positioned towards the vibrating feeder mechanism 5, and its feed end is connected to the discharge end of the vibrating screen bucket. The second sluice 432 is located directly below the vibrating screen bucket. The operator places LED beads into the funnel 42, where they fall from the bottom into the vibrating screen bucket. The vibrating screen bucket vibrates to feed the LED beads, causing them to fall into the first sluice 431 and then from the bottom of the first sluice 431 onto the vibrating feeder mechanism's vibrating plate.

[0033] Furthermore, the vibrating screen bucket includes a material screen 44, an elastic element 45 (using a spring sheet), and an electromagnet 47. The material screen 44 is connected to the support frame 41 through the elastic element 45. An armature 46 is provided on the side of the material screen 44 away from the first chute 431. The electromagnet 47 is installed on the support frame 41 and is correspondingly arranged on the armature 46. Vibration is generated by the high-frequency attraction between the electromagnet 47 and the armature 46, thereby driving the material screen 44 to vibrate and realizing the conveying of LED beads.

[0034] Furthermore, the feed hopper chute 43 is rotatably connected to the support frame 41 to adjust the angle of the feed hopper chute 43.

[0035] In this embodiment, refer to Figure 2 The vibratory feeder feeding mechanism 5 includes a vibratory feeder 51 and a linear feeder 52. The vibratory feeder 51 is located below the discharge port of the first chute 431. The LED beads flowing out of the first chute 431 directly enter the vibratory feeder. When the vibratory feeder vibrates, the LED beads are automatically oriented. Then, the linear feeder 52 transports the LED beads to the picking position in a single row.

[0036] In this embodiment, refer to Figures 7-9 The conveying mechanism 6 includes a base 61, a conveying motor 62, eccentric wheels 64, a swing arm 65, and a suction nozzle 66. The conveying motor 62 drives two eccentric wheels 64 to rotate simultaneously through a gear set 63. The two eccentric wheels 64 are connected to the swing arm 65 through bearings. Thus, when the conveying motor 62 drives the eccentric wheels 64 to rotate, it can drive the swing arm 65 to swing along a C-shaped trajectory.

[0037] Further, the conveying mechanism 6 further comprises a reversing mechanism, the reversing mechanism comprising a detection assembly 67 and a reversing assembly 68, the detection assembly 67 being used for detecting the pin direction of the LED lamp bead, the detection assembly 67 comprising a static material channel glass sheet 671, a backlight lamp plate 672 peripherally surrounding the static material channel glass sheet 671, and a camera 673 arranged below the static material channel glass sheet 671; the reversing assembly 68 being used for driving the LED lamp bead to rotate, the reversing assembly 68 comprising a reversing head 681 and a hollow stepping motor 682 driving the reversing head 681 to rotate; three of the suction nozzles 66 are mounted on the swing arm 65, when the eccentric wheel 64 is driven by the conveying motor 62 to rotate, the three suction nozzles 66 respectively reciprocate between the material taking position and the detection assembly 67, between the detection assembly 67 and the reversing assembly 68, and between the reversing assembly 68 and the material placing position.

[0038] It can be understood that the first suction nozzle 66 sucks the LED lamp bead at the material taking position of the linear feeder 52 and places the LED lamp bead on the static material channel glass sheet 671, the camera 673 detects the LED lamp bead, the second suction nozzle 66 conveys the detected LED lamp bead to the reversing head 681, the hollow stepping motor 682 drives the reversing head 681 to rotate, so that the pin direction of the LED lamp bead is kept consistent, and the third suction nozzle 66 sucks the reversed LED lamp bead and conveys the LED lamp bead to the material taking position (the material taking position of the linear track 713), the width of the linear track 713 can limit the LED lamp bead, so that the LED lamp bead is kept in the pin direction for conveying.

[0039] In the embodiment, with reference to Figure 2 , the rack 1 comprises a rack body 11, a fixed plate 12 and a height adjusting mechanism 13 (a pneumatic cylinder is adopted), the linear feeding mechanism 7 and the mounting plate 2 are arranged on the fixed plate 12, and the height adjusting mechanism 13 is arranged on the rack body 11 and is used for driving the fixed plate 12 to ascend and descend, so that the height of the linear feeding mechanism 7 can be adjusted to adapt to different models of chip mounters.
