DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figures 1 to 9 , an embodiment provided by the utility model:

[0031] A choke coil feeding tray, comprising a tray bottom 4 for placing a choke coil 1, and a feeding section 5 arranged above the tray bottom 4, wherein the feeding section 5 is arranged upward in a spiral around the center of the tray bottom 4, the starting end of the feeding section 5 is connected to the inside of the tray bottom 4, and the end of the feeding section 5 is connected with a material separation section and a screening section in sequence;

[0032] The material distribution section includes an upper track 6 connected to the end of the feeding section 5, and a lower track 7 connected to the end of the upper track 6. A material drop opening 10 is provided between the upper track 6 and the feeding section 5. There is a step structure between the upper track 6 and the lower track 7. The inner side of the lower track 7 is inclined. A guide rod 11 is provided on the outer side of the lower track 7.

[0033] The screening section includes a material selection channel 8 connected to the end of the lower track 7, and a discharge channel 9 connected to the end of the material selection channel 8. A discharge port 12 is provided between the material selection channel 8 and the discharge channel 9. A turning rod 13 is provided on the inner side of the material selection channel 8. The turning rod 13 corresponds to the position of the discharge port 12. The choke coil 1 overlaps the outer side of the discharge channel 9.

[0034] The choke coil 1 includes a spiral portion 2 located in the middle and pin portions 3 located at both ends. The cross section of the choke coil 1 is a P-shaped structure. The beginning of the pin portion 3 is connected to the spiral portion 2, and the end of the pin portion 3 extends outward. The end of the pin portion 3 forms an angle Y with the outer side of the spiral portion 2 (see Fig. 9 In the present technical solution, the curved structure formed by the angle Y of the choke coil 1 can be used to overlap with the outer side of the discharge channel 9, so as to distinguish the placement direction of the choke coil 1, thereby achieving the purpose of screening.

[0035] The disc bottom 4 is a disc-shaped structure, and the outer side of the disc bottom 4 is surrounded by a disc wall, and the choke coil 1 is placed inside the disc bottom 4. The disc bottom 4 can be a spherical structure with a central convexity, which is conducive to the choke coil 1 to tilt toward the outer side of the disc bottom 4, and the choke coil 1 can easily enter the feeding section 5. The feeding section 5 is located above the disc bottom 4, and is arranged to extend upward in a spiral shape with the center of the disc bottom 4 as the axis. The feeding section 5 can be arranged around the inner side of the disc wall, the outer side of the feeding section 5 is the disc wall, and the inner side of the feeding section 5 is an open structure. When the choke coil 1 is stacked too much in the feeding section 5, it falls from the inner side of the feeding section 5 and re-enters the inside of the disc bottom 4. The starting end of the feeding section 5 is connected to the inside of the disc bottom 4, the starting end of the material distribution section is connected to the end of the feeding section 5, and the starting end of the screening section is connected to the end of the material distribution section. The bottom of the disc bottom 4 can be provided with a vibration mechanism. Under the drive of the vibration mechanism, the choke coil 1 located inside the disc bottom 4 moves in a certain direction, passing through the feeding section 5, the material distribution section and the screening section in sequence.

[0036] The material distribution section includes an upper track 6 and a lower track 7 arranged side by side. The starting end of the upper track 6 is connected to the end of the feeding section 5, and the starting end of the lower track 7 is connected to the end of the upper track 6. The drop opening 10 is located between the upper track 6 and the feeding section 5. The width of the starting end of the upper track 6 can be smaller than the width of the end of the feeding section 5, and the drop opening 10 is formed between the two. The drop opening 10 is an open structure. When the choke coil 1 is piled up too much at the end of the feeding section 5, the choke coil 1 that fails to enter the upper track 6 falls from the drop opening 10 and returns to the inside of the bottom 4 of the tray, realizing the diversion of the choke coil 1.

[0037] There is a step-like structure between the end of the upper rail 6 and the beginning of the lower rail 7, which may be connected by an inclined surface or a vertical surface. The inner side of the lower rail 7 is inclined, and the inner side of the lower rail 7 may be an inclined surface, which is inclined downward at an angle of 60 degrees. The guide rod 11 is located on the outer side of the lower rail 7, and can overlap with the pin portion 3 of the choke coil 1 to play a guiding role and adjust the direction of the pin portion 3. When the choke coil 1 leaves the upper rail 6, the choke coil 1 falls on the lower rail 7, and the choke coil 1 moves along the lower rail 7. The outer side of the choke coil 1 contacts the guide rod 11, and the pin portion 3 overlaps the guide rod 11. Under the guidance of the guide rod 11, the choke coil 1 rotates upward until the pin portion 3 fits with the inner side of the lower rail 7. The choke coil 1 is adjusted to be placed at an angle, and the pin portion 3 is uniformly facing upward to achieve the tilting of the choke coil 1.

[0038] The screening section includes a material selection channel 8 and a material discharge channel 9 connected end to end. The starting end of the material selection channel 8 is connected to the end of the lower track 7, and the starting end of the material discharge channel 9 is connected to the end of the material selection channel 8. The material discharge port 12 is located between the material selection channel 8 and the material discharge channel 9. The width of the starting end of the material discharge channel 9 can be smaller than the width of the end of the material selection channel 8, and the material discharge port 12 is formed between the two. The flip rod 13 is located on the inner side and can overlap with the pin portion 3 of the choke coil 1 to play a flipping role and adjust the direction of the pin portion 3. The flip rod 13 corresponds to the position of the material discharge port 12. The flip rod 13 can be located above the material discharge port 12, and the material discharge port 10 is an open structure. When the choke coil 1 leaves the lower track 7, the choke coil 1 fits against the inner side of the material selection path 8, and the choke coil 1 moves along the material selection path 8. The upper end of the choke coil 1 contacts the flip rod 13, and the pin portion 3 overlaps the guide rod 11. Under the guidance of the flip rod 13, the choke coil 1 rotates outward until the pin portion 3 contacts the surface of the material selection path 8. The choke coil 1 is adjusted to be placed horizontally, and the pin portion 3 is uniformly facing outward to achieve the flipping of the choke coil 1.

[0039] When the choke coil 1 passes through the discharge port 12, the width dimension suddenly decreases, and the outer side of the choke coil 1 loses the support of the surface of the material selection channel 8. The pin portion 3 is suspended outside the discharge channel 9, and under the action of gravity, the choke coil 1 rotates downward until the pin portion 3 contacts the outer side of the discharge channel 9. At this time, the angle Y of a part of the choke coil 1 faces downward, the angle Y is set opposite to the outer side of the discharge channel 9, the pin portion 3 is buckled and fixed to the outer side of the discharge channel 9, and the choke coil 1 overlaps the outer side of the discharge channel 9, so that the choke coil 1 stays in the discharge channel 9; the angle Y of another part of the choke coil 1 faces upward, the angle Y is set opposite to the outer side of the discharge channel 9, and the pin portion 3 slides relative to the outer side of the discharge channel 9, so that the choke coil 1 falls from the outer side of the discharge channel 9, and the choke coil 1 is screened. After screening, the choke coil 1 enters the discharge channel 9 at the same placement angle, is neatly arranged in the discharge channel 9, and is transported to the next process.

[0040] The utility model is suitable for a choke coil 1. The choke coil 1 located at the bottom 4 of the disk passes through a feeding section 5, a dividing section and a screening section in sequence, and is respectively in an upper track 6, a lower track 7, a material selection channel 8 and a material discharge channel 9, so as to realize the diversion, tilting, flipping and screening of the choke coil 1. The disorderly choke coils 1 are adjusted to the same placement angle and arranged in order, and transported to the next process. When workers weld them, there is no need to distinguish them with the naked eye and manually adjust the direction of the choke coil 1, thereby improving production efficiency and avoiding errors.

[0041] In this embodiment, preferably, the choke coil 1 includes a spirally wound spiral portion 2, with pin portions 3 extending outward from both ends of the spiral portion 2 respectively, and the two pin portions 3 are located on one side of the spiral portion 2 and are axially perpendicular to the spiral portion 2.

[0042] The choke coil 1 is made of a continuous copper wire, which is wound and bent. The spiral portion 2 is located in the middle of the choke coil 1, and has a spiral winding structure. The two pin portions 3 are connected to the two ends of the choke coil 1 at the beginning, and the ends extend in the same direction. It can be understood that the cross section of the choke coil 1 is a P-shaped structure, and the two pin portions 3 are located in the same plane, which is located outside the spiral portion 2, so that an angle Y is formed between the end of the pin portion 3 and the outside of the spiral portion 2 (see Fig. 9 ). When the angle Y of the choke coil 1 is set facing the outside of the discharge channel 9, after the choke coil 1 rotates downward, the choke coil 1 is overlapped and fixed with the outside of the discharge channel 9, so that the choke coil 1 stays inside the discharge channel 9. In addition, in this scheme, the dimensions A, B, and C correspond to the length, width, and thickness of the choke coil 1, respectively (see Figure 8 , Fig. 9 ).

[0043] In this embodiment, as a preference, the starting end of the upper track 6 is connected to the outer side of the end of the feeding section 5 , and the drop opening 10 is an open structure and is located on the inner side of the end of the feeding section 5 .

[0044] The starting end of the upper rail 6 is connected to the outer side of the end of the feeding section 5. The surface of the upper rail 6 is connected to the outer side wall of the feeding section 5, and the inner side wall of the upper rail 6 is connected to the surface of the feeding section 5. The drop opening 10 is located on the inner side of the end of the feeding section 5 and is arranged side by side with the starting end of the upper rail 6. The width of the end of the feeding section 5 may be greater than the width of the starting end of the upper rail 6, and the drop opening 10 is formed between the two. The drop opening 10 is an open structure, and the bottom may be connected to the inside of the bottom of the plate 4. The width of the inner side of the upper rail 6 may be greater than the width of the choke coil 1, and less than twice the width of the choke coil 1, limiting that only one choke coil 1 can enter the upper rail 6 at a time. The width of the drop opening 10 is greater than the length of the choke coil 1 to avoid jamming. When the choke coil 1 moves along the feeding section 5, under the action of centrifugal force, most of the choke coils 1 are transported along the outer side of the feeding section 5 and smoothly enter the upper track 6, and the remaining choke coils 1 are transported along the inner side of the feeding section 5, fall from the drop port 10, and return to the inside of the tray bottom 4.

[0045] In this embodiment, as a preference, a limiting rod 14 is provided on the outer side of the upper rail 6 , the limiting rod 14 is arranged toward the inner side of the upper rail 6 , and extends along the end direction of the upper rail 6 .

[0046] The limit rod 14 is located on the outside of the upper rail 6, and may be installed near the end of the upper rail 6, and has an arc-shaped structure, which is arranged toward the inside of the upper rail 6 and extends along the end of the upper rail 6. The distance between the limit rod 14 and the inside of the upper rail 6 may be equal to the thickness of the choke coil 1, and the choke coil 1 can pass between the two. When the choke coil 1 moves along the upper rail 6, the choke coil 1 contacts the limit rod 14, and the pin portion 3 overlaps the limit rod 14. Under the guidance of the flip rod 13, the choke coil 1 rotates inward until the pin portion 3 contacts the inside of the upper rail 6. The choke coil 1 is adjusted to be placed at an angle, and the pin portion 3 is uniformly facing upward. After the choke coil 1 completes its rotation, it passes between the limit rod 14 and the inside of the upper rail 6 and moves toward the end of the upper rail 6.

[0047] In this embodiment, as a preference, an intercepting rod 15 is provided at the end of the upper rail 6 , the intercepting rod 15 is suspended, and a sliding opening 16 is provided between the intercepting rod 15 and the inner side of the lower rail 7 .

[0048] The intercepting rod 15 is located at the end of the upper rail 6, and can be an arc-shaped structure, suspended and parallel to the inner side of the lower rail 7. The sliding opening 16 is located between the intercepting rod 15 and the inner side of the lower rail 7, and the width of the sliding opening 16 can be equal to the thickness of the choke coil 1, and the choke coil 1 can pass through the sliding opening 16. The inner side of the upper rail 6 is connected with the inner side of the lower rail 7, and the inner side of the lower rail 7 is a downwardly inclined slope, which allows the choke coil 1 to slide to the surface of the lower rail 7. When the choke coil 1 leaves the end of the upper rail 6, the choke coil 1 remains tilted, and the intercepting rod 15 limits the choke coil 1 to prevent the choke coil 1 from flipping outward. Then, the choke coil 1 enters the sliding opening 16, and slides along the inner side of the lower rail 7 to the surface of the lower rail 7, thereby improving the stability of the choke coil 1 when it falls on the lower rail 7.

[0049] In this embodiment, as a preference, the guide rod 11 is disposed toward the inner side of the lower rail 7 and extends along the end direction of the lower rail 7 .

[0050] The guide rod 11 is located on the outside of the lower track 7, and may be installed near the end of the lower track 7, and has an arc-shaped structure, and is arranged toward the inside of the lower track 7, and extends along the end of the lower track 7. The distance between the guide rod 11 and the inside of the lower track 7 may be equal to the thickness of the choke coil 1, and the choke coil 1 can pass between the two. When the choke coil 1 moves along the lower track 7, the choke coil 1 contacts the guide rod 11, and the pin portion 3 overlaps the guide rod 11. Under the guidance of the guide rod 11, the choke coil 1 rotates upward until the pin portion 3 contacts the inside of the lower track 7. The choke coil 1 is adjusted to be placed at an angle, and the pin portion 3 is uniformly facing upward. After the choke coil 1 completes its rotation, it passes between the guide rod 11 and the inside of the lower track 7, and moves toward the end of the lower track 7. When the choke coil 1 is on the upper track 6, it is turned once by the limit rod 14. However, after falling from the upper track 6 to the lower track 7, the placement direction of part of the choke coil 1 is changed, and a second turn is made by the guide rod 11 to ensure that when the choke coil 1 enters the screening section, the pin portion 3 is uniformly facing upward.

[0051] In this embodiment, as a preference, a material drop opening 17 is provided between the material selection channel 8 and the lower track 7 , the starting end of the material selection channel 8 is connected to the inner side of the end of the lower track 7 , the material drop opening 17 is an open structure, and is located on the outer side of the end of the lower track 7 .

The surface of the material selection channel 8 is connected to the surface of the lower track 7, and the inner side wall of the material selection channel 8 is connected to the inner side wall of the lower track 7. The material drop opening 17 is located on the outer side of the end of the lower track 7 and is arranged side by side with the starting end of the material selection channel 8. The width of the end of the lower track 7 is greater than the width of the starting end of the material selection channel 8, and the material drop opening 17 is formed between the two. The material drop opening 17 is an open structure, and the bottom is connected to the inside of the plate bottom 4. The width of the surface of the material selection channel 8 may be greater than the thickness of the choke coil 1 and less than the width of the choke coil 1, limiting the choke coil 1 from entering the material selection channel 8 in an inclined state. When the choke coil 1 moves along the lower track 7, it is first turned by the guide rod 11, and the choke coil 1 is adjusted to be tilted, and the pin portion 3 is uniformly facing upward, and then enters the material selection channel 8 from the end of the lower track 7. During this period, the choke coil 1 remains tilted, and the pin portion 3 remains in contact with the inner side of the material selection channel 8. If the choke coil 1 rotates during this process, the pin portion 3 leaves the inner side wall of the material selection channel 8 and falls from the material drop opening 17 and returns to the inside of the disc bottom 4 .

[0053] In this embodiment, as a preference, a receiving platform 18 extending outward is provided at the end of the material selection channel 8, the flip rod 13 is located above the receiving platform 18, the flip rod 13 is arranged toward the outside of the receiving platform 18, and extends along the end of the receiving platform 18.

[0054] The receiving platform 18 is located at the end of the material selection channel 8, extending outward from the outside of the material selection channel 8, and connected to the surface of the material selection channel 8. The width of the receiving platform 18 can be greater than the width of the choke coil 1, and the length of the receiving platform 18 can be greater than the length of the choke coil 1. The choke coil 1 can be placed horizontally on the surface of the receiving platform 18. The flip rod 13 is located above the receiving platform 18, and can be an arc-shaped structure, suspended, and parallel to the surface of the receiving platform 18. One end of the flip rod 13 can be connected to the inner side wall of the material selection channel 8, and the other end of the flip rod 13 can be set toward the outside of the receiving platform 18 and extend along the end of the receiving platform 18. The distance between the flip rod 13 and the receiving platform 18 can be equal to the thickness of the choke coil 1, and the choke coil 1 can pass between the two. When the choke coil 1 moves along the material selection path 8, the upper end of the choke coil 1 contacts the flip rod 13, the pin portion 3 overlaps the flip rod 13, and under the guidance of the flip rod 13, the choke coil 1 rotates outward until the pin portion 3 contacts the surface of the receiving platform 18, and the choke coil 1 is adjusted to be placed horizontally, with the pin portions 3 uniformly facing outward. At this time, the choke coil 1 is divided into a prone state and a supine state. When the choke coil 1 is in the prone state, the angle Y of the choke coil 1 faces downward, and is arranged opposite to the surface of the receiving platform 18. When the choke coil 1 is in the supine state, the angle Y of the choke coil 1 faces upward, and is arranged opposite to the surface of the receiving platform 18.

The width of the end of the receiving platform 18 is greater than the width of the starting end of the discharge channel 9, and the discharge port 12 is formed between the two. The discharge port 12 is an open structure, and the bottom is connected to the inside of the bottom of the plate 4. The width of the surface of the discharge channel 9 may be greater than the thickness of the choke coil 1, and less than the width of the choke coil 1. When the choke coil 1 passes through the discharge port 12, the outer side of the choke coil 1 loses the support of the surface of the receiving platform 18, and the pin portion 3 is suspended outside the discharge channel 9. Under the action of gravity, the choke coil 1 rotates downward. At this time, the choke coil 1 in the prone state has its angle Y facing the outside of the discharge channel 9, the pin portion 3 is fastened and fixed with the outside of the discharge channel 9, and the choke coil 1 overlaps the outside of the discharge channel 9, so that the choke coil 1 stays in the discharge channel 9.
