DETAILED DESCRIPTION

[0027] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0028] Implementation method 1: Figures 1 - 6 As shown, a circular feeding device for scattered components of an LED bulk placement machine includes a base 1, a support plate 2, an annular plate 3, a feeding track 4, a circular plate 5, a mounting rod 6, a spiral plate 7, a driving mechanism and a flipping mechanism. Six support plates 2 are connected to the top of the base 1 at evenly spaced intervals in the circumferential direction by bolts, and the tops of the six support plates 2 are commonly connected to the annular plate 3, the front side of the annular plate 3 is connected to the feeding track 4, the bottom of the annular plate 3 is rotatably connected to the circular plate 5, the rear side of the top of the annular plate 3 is connected to the mounting rod 6, the lower end of the mounting rod 6 is connected to the spiral plate 7, the spiral plate 7 is located in the annular plate 3, the driving mechanism is used to drive the circular plate 5 to rotate, so that the scattered components move along the spiral plate 7 to the feeding track 4, and the flipping mechanism is used to flip the scattered components on the reverse side.

[0029] like Figure 2 and Figure 3 As shown, the driving mechanism includes a first motor 8, a rotating shaft 9 and a rotating frame 10. The first motor 8 is connected to the middle of the top of the base 1 by bolts, the rotating shaft 9 is connected to the output shaft of the first motor 8 through a coupling, the upper end of the rotating shaft 9 is connected to the rotating frame 10, and the top of the rotating frame 10 is connected to the bottom of the circular plate 5.

[0030] like Figures 4 - 6 As shown, the flipping mechanism includes a flipping track 11, a mounting plate 12, an electric push rod 13, a push block 14, a material blocking plate 15, a mounting frame 16, a visual sensor 17 and a controller 18. The top middle of the feeding track 4 is connected to the flipping track 11. For the specific structure of the flipping track 11, please refer to Figure 5, the turning track 11 is a continuous structure composed of an inclined section, an arc section and a horizontal section. The rear side of the bottom of the turning track 11 is connected with a mounting plate 12 by bolts. The top of the mounting plate 12 is connected with an electric push rod 13 by bolts. The telescopic rod of the electric push rod 13 slides through the rear side of the turning track 11. The front end of the telescopic rod of the electric push rod 13 is connected with a push block 14. The rear side of the top of the turning track 11 is slidably connected with a material retaining plate 15. An activity groove 151 is opened at the bottom of the material retaining plate 15. The push block 14 is located in the activity groove 151. The right side of the top of the feeding track 4 is connected with a mounting frame 16 by bolts. The left side of the mounting frame 16 is connected with a visual sensor 17 by bolts. The top of the mounting frame 16 is connected with a controller 18. The electric push rod 13 and the visual sensor 17 are both electrically connected to the controller 18.

[0031] The staff starts the first motor 8. The output shaft of the first motor 8 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the rotating frame 10 to rotate. The rotating frame 10 drives the circular plate 5 to rotate. The scattered components are placed on the circular plate 5. The circular plate 5 drives the scattered components to move. The scattered components move along the spiral plate 7 into the feeding track 4. The vision sensor 17 detects the front and back sides of the scattered components. The scattered components on the front side move left along the feeding track 4 for feeding. The LED bulk component mounter picks up the scattered components in the feeding track 4 for mounting. When the vision sensor 17 detects the scattered components on the back side, the vision sensor 17 sends a signal. After receiving the signal, the controller 18 controls the telescopic rod of the electric push rod 13 to extend, driving the push block 14 to move forward. The push block 14 moves in the movable slot 151. When the push block 14 moves to the front end of the movable slot 151, the push block 14 will push the baffle 15 forward. The baffle 15 will enter the turning track 11. Subsequently, the scattered components on the back side will enter the turning track 11. The push block 14 will push the scattered components on the back side, causing the scattered components on the back side to move along the turning track 11 for turning over. Subsequently, the telescopic rod of the electric push rod 13 will shorten, driving the push block 14 to move backward. The push block 14 moves in the movable slot 151. When the push block 14 moves to the rear end of the movable slot 151, the push block 14 will push the baffle 15 backward to reset the baffle 15. The push block 14 will push the scattered components on the back side that subsequently enter the turning track 11, causing the scattered components on the back side to move along the turning track 11. When the scattered components on the back side move to the inclined position at the upper part of the turning track 11, the turning over of the scattered components on the back side is completed. The scattered components on the back side after turning over will move backward along the inclined position at the upper part of the turning track 11. The scattered components on the back side after turning over are pushed to the inclined position at the upper part of the turning track 11 by the push block 14. Therefore, at this time, the baffle 15 is located in the turning track 11. The baffle 15 can block the scattered components on the back side after turning over to prevent the scattered components on the back side after turning over from falling behind the push block 14. When the push block 14 moves backward, the push block 14 will push the baffle 15 backward to reset the baffle 15. At this time, the baffle 15 no longer blocks the scattered components on the back side after turning over. The scattered components on the back side after turning over will fall into the lower part of the turning track 11. The scattered components on the back side after turning over will be pushed by the push block 14 to align with the feeding track 4. The scattered components in the feeding track 4 will push the scattered components on the back side after turning over, pushing the scattered components on the back side after turning over into the feeding track 4 for feeding. It does not require manual intervention or reloading, greatly simplifying the operation steps, thereby improving the mounting efficiency.

[0032] Embodiment 2: On the basis of Embodiment 1, as Figure 7 and Figure 8As shown, it also includes a second motor 19, a turntable 20, a toggle block 21 and a buffer spring 22. The second motor 19 is connected to the right front part of the feed track 4 by bolts, the turntable 20 is connected to the output shaft of the second motor 19, the toggle block 21 is slidably connected to the front side of the turntable 20, an opening 211 is opened on the right front part of the feed track 4, the toggle block 21 passes through the opening 211 and enters the feed track 4, a buffer spring 22 is connected between the toggle block 21 and the turntable 20, and the buffer spring 22 is located in the turntable 20.

[0033] When feeding, the second motor 19 is started, and the output shaft of the second motor 19 drives the turntable 20 to rotate, and the turntable 20 drives the toggle block 21 to rotate, and the toggle block 21 passes through the opening 211 and enters the feeding track 4. Then the toggle block 21 pushes the scattered components in the feeding track 4 to move to the left to prevent the scattered components from being stranded in the feeding track 4. When the toggle block 21 contacts the scattered components, the buffer spring 22 adaptively deforms to prevent the toggle block 21 from squeezing the scattered components, thereby preventing the scattered components from being damaged.

[0034] like Figure 9 As shown, it also includes a storage frame 23, a connecting rod 24 and a push plate 25. The storage frame 23 is connected to the left front side of the feeding track 4, the connecting rod 24 is connected to the rear side of the baffle plate 15, and the front end of the connecting rod 24 is connected to the push plate 25. The push plate 25 is located inside the feeding track 4.

[0035] The scattered components will move along the feeding track 4 to the front side of the pushing plate 25. When the blocking plate 15 moves forward, it will drive the connecting rod 24 to move forward. The connecting rod 24 drives the pushing plate 25 to move forward. The pushing plate 25 can push the scattered components in the feeding track 4 into the storage frame 23. The scattered components are stored in the storage frame 23 to prevent the scattered components from being blocked in the feeding track 4.

[0036] like Figure 10 As shown, it also includes a limiting block 26 and a screw rod 27. The limiting block 26 is slidably connected to the front side of the top of the annular plate 3, and the screw rod 27 is rotatably connected to the right side of the top of the feeding track 4. The screw rod 27 and the limiting block 26 are connected by threads.

[0037] like Figure 10 As shown, a limiting plate 28 is also included. The limiting plate 28 is connected to the rear side of the limiting block 26. The limiting plate 28 is located inside the annular plate 3. A notch is provided at the bottom of the limiting plate 28 for accommodating the spiral plate 7.

[0038] When the staff place the scattered components on the circular plate 5, the scattered components may stack together. The limiting block 26 and the limiting plate 28 can push down the overlapping scattered components, enabling the scattered components to enter the feeding track 4 neatly and orderly. By rotating the screw rod 27, the limiting block 26 can be driven to move up and down, and the limiting block 26 can drive the limiting plate 28 to move up and down. By adjusting the heights of the limiting block 26 and the limiting plate 28, the heights of the limiting block 26 and the limiting plate 28 can be adjusted according to the height of the scattered components to adapt to scattered components of different heights.

[0039] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
