Technical Field

[0001] The present invention relates to the technical field of electric vehicle component processing, and in particular to a screening and feeding device containing curved magnetic steel and a screening method. Background Art

[0002] Magnets are used in many parts of working and transport equipment, especially in vehicles. For example, in wheels, magnets can keep the wheels balanced and prevent nuts from falling off. Magnets come in many shapes and sizes.

[0003] There is an existing magnet used for the rear wheel of an electric vehicle, which is formed in a cube shape, but one of the larger faces is a curved surface, and the other relatively larger face is a flat surface. Before the magnet is installed on the device, it generally needs to be marked. The above-mentioned magnet with a curved surface needs to be marked on the curved surface, but the amount of magnets produced is very large. If they are turned over and marked manually one by one, it will waste a lot of time and manpower, increasing costs. Summary of the invention

[0006] Furthermore, the screening and conveying track is arranged to be inclined, and the inclined lower end is connected to the inner baffle plate; the inclination angle of the screening and conveying track is 35-45 degrees; the width of the outer baffle plate baffle surface is shorter than the width of the inner baffle plate baffle surface, and longer than the width of the screening and conveying track, and when the flat or curved surface with a larger area relative to the magnetic steel fits the inner baffle plate and moves, the width of the screening and conveying track matches the width of the surface where the magnetic steel contacts the screening and conveying track.

[0007] Furthermore, the sorting mechanism includes an inverted L-shaped spacer, the horizontal end of the spacer is connected to the loading baffle, and the vertical lower end is connected to the end of the spiral loading plate. The spacer, the loading baffle and the spiral loading plate form a feeding channel, and the size of the feeding channel is large enough for a magnet to pass through.

[0008] Furthermore, the end of the inner baffle plate close to the sorting mechanism and the upper end of the spiral feeding plate are in the same plane, and the inclination angle of the inner baffle plate gradually increases along the conveying direction until it becomes perpendicular to the screening conveying track and no longer increases.

[0009] Furthermore, the flipping mechanism includes a flipping vibrator and a flipping panel, the flipping vibrator is arranged on the inner side of the inner baffle plate, the flipping panel is arranged on the outer side of the screening and conveying track, the position where the flipping panel is provided is not provided with an outer baffle plate, and the flipping panel is correspondingly arranged on the outer side of the flipping vibrator; the position where the flipping panel and the screening and conveying track are connected is a curved surface; the front end of the flipping panel is also provided with a guide member inclined inward.

[0010] Furthermore, the end of the outer baffle plate in front of the flap panel is in the same plane as the flap panel, and the inclination angle of the outer baffle plate in front of the flap panel gradually increases along the conveying direction until it is arranged vertically upward.

[0011] Furthermore, the judging and rejecting mechanism includes a judging vibrator, and the judging vibrator is arranged on the inner side of the inner baffle plate, and no outer baffle plate is arranged on the outer side of the screening sequence conveying track where the judging vibrator is arranged.

[0012] Furthermore, the inclination angle of the end of the inner baffle away from the sorting mechanism along the conveying direction gradually decreases until it is set horizontally, and the magnetic steel at the end of the inner baffle faces downward with a flat surface and upward with a curved surface.

[0013] Furthermore, it also includes a guide plate, the inner ring frame is provided with a feeding opening at a position close to the bottom of the spiral feeding plate, the guide plate is arc-shaped, and one end is connected to the inner side surface of the outer ring frame, and the other end is connected to the side surface of the feeding opening, and the feeding opening communicates with the inside and outside of the inner ring frame; the outer ring frame is provided with a discharge opening at a position extending out of the outer ring frame corresponding to the screening conveying track, and the discharge opening is not provided at the corresponding lower part of the screening conveying track; the screening conveying track is connected to the inner ring frame through a plurality of connecting rods;

[0014] The inner side surface of the spiral feeding plate is higher than the outer side surface.

[0015] In order to achieve the above object, the present invention also provides a screening method based on the above screening and feeding device containing curved magnetic steel, and its innovation lies in: specifically comprising the following steps:

[0016] S1. Vibration loading: The magnetic steels to be screened are placed on the main body of the vibration plate and located in the inner ring frame. The magnetic steels are gradually transported upward through the spiral loading plate due to the vibration of the vibration plate. The relatively large flat or curved surface of the magnetic steels is transported by contacting the spiral loading plate due to vibration. Since the inner side of the spiral loading plate is higher than the outer side, the magnetic steels are transported outside on the spiral loading plate, that is, close to the inner ring frame, until they are transported to the top of the spiral loading plate.

[0017] S2. Sorting and conveying: The magnetic steels conveyed to the top of the spiral feeding plate enter the screening and conveying track through the feeding slot one by one. Since the end of the inner baffle plate close to the spiral feeding plate and the upper end of the spiral feeding plate are in the same plane, the plane or curved surface of the magnetic steel just entering the screening and conveying track is located on the screening and conveying track and the inner baffle plate. With the vibration movement, the inclination angle of the inner baffle plate gradually increases. Since the width of the baffle surface of the inner baffle plate is longer than the width of the screening and conveying track, the plane or curved surface of the magnetic steel gradually moves with the inclination of the inner baffle plate, and the side surface between the plane and curved surface of the magnetic steel contacts the screening and conveying track and moves;

[0018] S3. Face judgment flip: when the magnetic steel is transported to the position of the corresponding flip vibrator on the screening conveyor track;

[0019] S31. If the side surface close to the inner baffle is flat and in full contact with the inner baffle, due to the gravity of the magnet itself, the vibration of the flip vibrator is not enough to make the magnet slide out of the screening conveyor track, and the magnet is still transported forward along the inner baffle in the screening conveyor track;

[0020] S32. If the side surface close to the inner baffle is a curved surface, the contact area with the inner baffle is small and the contact is unstable. Under the dual vibration of the vibration plate body and the flip vibrator, the magnet is vibrated and bounced up, and slides out of the screening conveyor track and slides onto the flip panel. The curved surface of the magnet on the flip panel faces downward and the flat surface faces upward. On the flip panel, it continues to move forward due to the vibration of the vibration plate body.

[0021] S33. Because the end of the outer baffle plate in front of the flap plate is in the same plane as the flap plate, the magnetic steel gradually moves forward onto the outer baffle plate and the screening conveying track through the guidance of the guide member, and continues to move forward due to vibration. As the inclination angle of the outer baffle plate gradually increases, and because the width of the baffle surface of the outer baffle plate is longer than the width of the screening conveying track, the curved surface of the magnetic steel is gradually lifted and tilted in contact with the outer baffle plate until the outer baffle plate is in a vertical position, and the magnetic steel falls over and fits the inner baffle plate, so that the flat surface of the magnetic steel contacts the inner baffle plate and continues to be transported;

[0022] S4. Facing judgment rejection: When the magnet is transported forward to the judgment vibrator on the screening conveyor track, the magnet with a flat surface in contact with the inner baffle continues to be transported forward on the screening conveyor track. If there is still a magnet with a curved surface in contact with the inner baffle, the judged vibrator will vibrate and slide out of the screening conveyor track due to the unstable curved surface contact, and fall on the top surface of the vibration plate body between the inner ring frame and the outer ring frame;

[0023] S5. Outward transportation: The magnets that fall onto the top surface of the vibration disk body between the inner ring frame and the outer ring frame are transported to the loading opening due to the vibration of the vibration disk, and enter the inner ring frame to continue vibrating and loading, and steps S1-S4 are repeated; the magnets that are in flat contact with the inner baffle are transported on the screening and conveying track until the inclination angle of the inner baffle is gradually reduced to a horizontal level, and the curved surface of the magnets on the inner baffle faces upward.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] A screening and feeding device containing curved magnetic steel of the present invention is provided with a screening conveying track, an inner baffle, an outer baffle, a flipping mechanism and a judging and rejecting mechanism. The magnetic steels that have been sorted by the vibration plate are sent to the screening conveying track one by one for judging their orientation. The magnetic steels with the flat surface facing the inner baffle are directly transported forward, and the magnetic steels with the curved surface facing the inner baffle are flipped by the flipping mechanism, so as to ensure that the magnetic steels finally outputted are all with the flat surface facing the inner baffle, and the curved surface of the magnetic steel is facing upward by reducing the angle of the inner baffle, and then the curved surface is marked, so that the screening and flipping efficiency is high, the automation is strong, and time and labor costs are saved.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1

[0046] The present embodiment provides a screening and feeding device containing curved magnetic steel 1, comprising a vibrating plate feeder and magnetic steel 1, the vibrating plate feeder comprising a vibrating plate body 2 and an inner ring frame 3, an outer ring frame 4 and a spiral feeding plate 5 for conveying the magnetic steel 1, the inner ring frame 3 being arranged inside the outer ring frame 4 and outside the spiral feeding plate 5, and the outer ring frame 4 being arranged on the periphery of the upper surface of the vibrating plate body 2; Figure 1 and 2 As shown, it also includes a screening conveying track 6, which is arranged between the inner ring frame 3 and the outer ring frame 4; the top of the spiral loading plate 5 extends to above the inner ring frame 3, and the outer end of the top of the spiral loading plate 5 is connected to one end of the screening conveying track 6, and a sorting mechanism 7 is provided at the position where the spiral loading plate 5 is connected to the screening conveying track 6, and the other end of the screening conveying track 6 extends out of the outer ring frame 4; an upwardly inclined inner baffle plate 10 is provided on the inner side of the screening conveying track 6, and an outer baffle plate 11 is vertically provided on the outer side; a turning mechanism 8 and a facing judgment and rejection mechanism 9 are also provided on the screening conveying track 6, with the conveying direction as the front, and the facing judgment and rejection mechanism 9 is located in front of the turning mechanism 8; a loading baffle plate 12 is also provided on the periphery of the position where the spiral loading plate 5 extends to above the inner ring frame 3.

[0047] The present embodiment is provided with a combination of the screening conveying track 6, the inner baffle plate 10, the outer baffle plate 11, the flipping mechanism 8 and the judging and rejecting mechanism 9, which will send the magnetic steels 1 sorted by the vibration plate to the screening conveying track 6 one by one for orientation judgment, and the magnetic steels 1 with the flat surface facing the inner baffle plate 10 will be directly transported forward, and the magnetic steels with the curved surface facing the inner baffle plate 10 will be flipped by the flipping mechanism 8 and the inner baffle plate 10 and the outer baffle plate 11 in front of the flipping mechanism 8, to ensure that the magnetic steels 1 finally outputted can all have the flat surface facing the inner baffle plate 10, and the curved surface of the magnetic steel 1 is facing upwards by reducing the angle of the inner baffle plate 10, and then the curved surface is marked, so that the screening and flipping efficiency is high, the automation is strong, and time and labor costs are saved.

[0048] In this embodiment, the magnetic steel 1 whose curved surface is still facing the inner baffle 10 after passing through the turning mechanism 8 can be screened out and rejected by the rejection mechanism 9, thereby further ensuring the upward curved surface rate of the magnetic steel 1 when it is output. The vibration of the vibration plate in this embodiment causes the material to move counterclockwise for transportation.

[0049] Example 2

[0050] The screening and conveying track 6 of the present embodiment is inclined, and the inclined lower end is connected to the inner baffle plate 10; the inclination angle of the screening and conveying track 6 is 35-45 degrees; the width of the blocking surface of the outer baffle plate 11 is shorter than the width of the blocking surface of the inner baffle plate 10, and longer than the width of the screening and conveying track 6. When the flat or curved surface with a larger area relative to the inner baffle plate 10 moves, the width of the screening and conveying track 6 matches the width of the surface where the magnetic steel 1 contacts the screening and conveying track 6.

[0051] The rest is the same as in Example 1.

[0052] In this embodiment, the relatively large plane or curved surface refers to the fact that the magnetic steel 1 in the present invention is a cube, but one of the larger faces is a curved surface, and among the six faces of a rectangular parallelepiped shape, there are two relatively largest faces, one of which is a curved surface, which is the shape of the magnetic steel 1 in the present invention. When one of the larger faces moves in contact with the inner baffle 10, the face between the two larger faces will move in contact with the screening conveying track 6.

[0053] Example 3

[0054] The sorting mechanism 7 of this embodiment includes an inverted L-shaped spacer 71, such as Figure 3 As shown, the horizontal end of the spacer 71 is connected to the loading baffle 12, and the vertical lower end is connected to the end of the spiral loading plate 5. The spacer 71, the loading baffle 12 and the spiral loading plate 5 form a feeding slot 72, and the size of the feeding slot 72 is large enough for a magnet 1 to pass through.

[0055] Preferably, the end of the inner baffle plate 10 of this embodiment close to the sorting mechanism 7 and the upper end of the spiral feeding plate 5 are in the same plane, and the inclination angle of the inner baffle plate 10 gradually increases along the conveying direction until it is perpendicular to the screening conveying track 6 and no longer increases.

[0056] The rest is the same as Example 2.

[0057] The arrangement of the sorting mechanism 7 can prevent the magnetic steels 1 conveyed from the spiral loading plate 5 from overlapping and entering the screening conveying track 6, thereby preventing the subsequent turning over and judging and rejecting of the magnetic steels 1 by the turning over mechanism 8 and the judging and rejecting mechanism 9, thereby ensuring that the materials pass through the screening conveying track 6 one by one in an orderly manner for judging, turning over or rejecting, thereby ensuring that automatic screening is carried out in an orderly manner.

[0058] Because the magnetic steel 1 is vibrated and fed on the spiral feeding plate 5 by the vibration of the vibration disk body, it can ensure that a larger surface of the magnetic steel 1 fits the spiral feeding plate 5 for transportation. The end of the inner baffle plate 10 close to the sorting mechanism 7 and the upper end of the spiral feeding plate 5 are on the same plane, which can ensure that most of the bottom surface of the magnetic steel 1 entering the screening and conveying track 6 fits the inner baffle plate 10, ensuring that when the inner baffle plate 10 is subsequently tilted and lifted, the flat or curved surface with a larger area of ​​the magnetic steel 1 moves along with the tilted fit of the inner baffle plate 10.

[0059] Example 4

[0060] The flipping mechanism 8 of this embodiment includes a flipping vibrator 81 and a flipping panel 82. Figure 4 and 5 As shown, the flip vibrator 81 is arranged on the inner side of the inner baffle plate 10, and the flip panel 82 is arranged on the outer side of the screening and conveying track 6. The outer baffle plate 11 is not arranged at the position where the flip panel 82 is arranged, and the flip panel 82 is correspondingly arranged on the outer side of the flip vibrator 81; the position where the flip panel 82 and the screening and conveying track 6 are connected is a curved surface; the front end of the flip panel 82 is also provided with a guide member 83 inclined inward.

[0061] Preferably, the end of the outer baffle 11 in front of the flap panel 82 of this embodiment is in the same plane as the flap panel 82, and the inclination angle of the outer baffle 11 in front of the flap panel 82 gradually increases along the conveying direction until it is set vertically upward.

[0062] The rest is the same as in Example 3.

[0063] When this embodiment is used in practice, if the flat surface contacts the inner baffle plate 10 and moves, the contact is stable due to the inclined movement and the flat surface completely fits the inner baffle plate 10, and the vibration of the flip vibrator 81 is not enough to make it pop out; if the curved surface contacts the inner baffle plate 10 and moves, the contact between the curved surface and the flat surface is only a small surface contact or point contact. Even if it is a small surface contact, the various parts of the contact surface are not completely in contact due to the curved surface, that is, the contact is not compact and not in contact, which makes it easy to slide out of the screening and conveying track 6 when it is vibrated from the inside of the inner baffle plate 10. The part where the flip panel 82 and the screening and conveying track 6 are connected is a curved surface, which makes it even more likely that when the magnetic steel 1 vibrates and bounces up, the curved surface of the magnetic steel 1 contacts the curved surface connecting the panel and the screening and conveying track 6 and slides out of the screening and conveying track 6, so that the curved surface of the magnetic steel 1 that finally slides to the flip panel 82 faces downward.

[0064] The guide plate 13 of this embodiment can accurately guide the magnetic steel 1 on the flip panel 82 forward to the outer baffle 11. The end of the outer baffle 11 located in front of the flip panel 82 is in the same plane as the flip panel 82, which facilitates the magnetic steel 1 to move directly to the outer baffle 11 through the guide.

[0065] Example 5

[0066] The judging and rejecting mechanism 9 of this embodiment includes a judging vibrator 91, such as Fig.12 As shown, the judging vibrator 91 is arranged on the inner side surface of the inner baffle plate 10, and the outer side of the screening conveying track where the judging vibrator 91 is arranged is not provided with an outer baffle plate 11.

[0067] The rest is the same as Example 4.

[0068] The judging and rejecting mechanism 9 and the flipping mechanism 8 of this embodiment have the same principles, except that the flipping panel 82 is not provided for the judging and rejecting mechanism, and the outer baffle plate 11 is not provided at the position corresponding to the judging vibrator 91. When the magnetic steel 1 with the curved surface still facing the inner baffle plate 10 is vibrated and ejected by the judging vibrator 91, it falls downward onto the vibration disk body for rejection due to the lack of the outer baffle plate 11 to block it.

[0069] Example 6

[0070] The end of the inner baffle plate 10 of this embodiment away from the sorting mechanism 7 is gradually inclined in the conveying direction until it is set horizontally, and the magnetic steel 1 faces downward on the flat surface of the end of the inner baffle plate 10 and faces upward on the curved surface.

[0071] The rest is the same as Example 5.

[0072] After the judging and rejecting mechanism 9, when the magnetic steel 1 whose plane is in contact with the inner baffle plate 10 is transported to the end of the screening conveying track 6, due to the horizontal setting of the inner baffle plate 10, the curved surface of the magnetic steel 1 faces upward. In actual use, the conveying end of the screening conveying track 6 can be connected with a conveyor belt to transport the magnetic steel 1 with the curved surface facing upward to the next process for marking and printing.

[0073] Example 7

[0074] This embodiment further includes a guide plate 13 on the basis of embodiment 6. A loading opening 14 is provided at a position of the inner ring frame 3 near the bottom of the spiral loading plate 5. The guide plate 13 is arc-shaped, and one end is connected to the inner side surface of the outer ring frame 4, and the other end is connected to the side surface of the loading opening 14. The loading opening 14 connects the inside and outside of the inner ring frame 3. A discharge opening 15 is provided at a position of the outer ring frame 4 corresponding to the screening conveying track 6 that extends out of the outer ring frame 4. The discharge opening 15 is not provided at the corresponding lower part of the screening conveying track 6. The screening conveying track 6 is connected to the inner ring frame 3 through a number of connecting rods 16.

[0075] Preferably, the inner side of the spiral feeding plate 5 of this embodiment is higher than the outer side. Fig.15 shown.

[0076] The rest is the same as in Example 1.

[0077] In this embodiment, the guide plate 13 mainly guides the magnetic steel 1 rejected by the judging and rejecting mechanism 9 into the inner ring frame 3, so that the rejected magnetic steel 1 can be fed, conveyed and screened for the second time.

[0078] The setting that the inner side surface of the spiral loading plate 5 is higher than the outer side surface can ensure that the magnetic steel 1 is located on the outside when vibrating and loading on the spiral loading plate 5, and ensure that when loading to the upper end of the spiral loading plate 5, the magnetic steel 1 is located at the outer end of the spiral loading plate 5, which is convenient for entering the screening conveying track through the feeding slot 72.

[0079] Example 8

[0080] This embodiment provides a screening method for a screening and feeding device containing curved magnetic steel 1 based on the above-mentioned embodiments 1-7, such as Fig.16 As shown, the specific steps include:

[0081] S1. Vibration loading: The magnetic steels 1 to be screened are all placed on the main body of the vibration plate and located in the inner ring frame 3. The magnetic steels 1 are gradually transported upward through the spiral loading plate 5 due to the vibration of the vibration plate. The relatively large flat or curved surface of the magnetic steels 1 is transported by contacting the spiral loading plate 5 due to vibration. Since the inner side surface of the spiral loading plate 5 is higher than the outer side surface, the magnetic steels 1 are transported outside on the spiral loading plate 5, that is, transported close to the inner ring frame 3, until they are transported to the top of the spiral loading plate 5.

[0082] S2. Sorting and conveying: The magnetic steels 1 conveyed to the top of the spiral loading plate 5 pass through the feed slot 72 one by one and enter the screening and conveying track 6. Because the end of the inner baffle 10 close to the spiral loading plate 5 and the upper end of the spiral loading plate 5 are in the same plane, the plane or curved surface of the magnetic steel 1 just entering the screening and conveying track 6 is located on the screening and conveying track 6 and the inner baffle 10. With the vibration movement, the inclination angle of the inner baffle 10 gradually increases, and because the width of the baffle surface of the inner baffle 10 is longer than the width of the screening and conveying track 6, the plane or curved surface of the magnetic steel 1 gradually moves with the inclination of the inner baffle 10, and the side surface between the plane and the curved surface of the magnetic steel 1 contacts the screening and conveying track 6, as shown in FIG. Figure 6 As shown, the inner baffle 10 is tilted and moved in accordance with the curved surface;

[0083] S3. Face judgment flip: When the magnetic steel 1 is transported to the corresponding flip vibrator 81 on the screening conveyor track 6;

[0084] S31. If the side surface close to the inner baffle 10 is a plane and is completely in contact with the inner baffle 10, due to the gravity of the magnet 1 itself, the vibration of the flip vibrator 81 is not enough to make the magnet 1 slide out of the screening conveyor track 6, and the magnet 1 is still transported forward in the screening conveyor track 6 against the inner baffle 10;

[0085] S32. If the side surface close to the inner baffle 10 is a curved surface, the contact area with the inner baffle is small and the contact is unstable. Under the dual vibration of the vibration plate body 2 and the flip vibrator 81, the magnetic steel 1 is vibrated and bounced up, such as Figure 7 As shown, the magnetic steel 1 on the flip panel 82 is slid out of the screening conveying track 6 and onto the flip panel 82, with the curved surface of the magnetic steel 1 facing downward and the flat surface facing upward. Figure 8 As shown, the flap 82 continues to move forward due to the vibration of the vibration plate body 2;

[0086] S33. Because the outer baffle 11 end portion located in front of the flip panel 82 and the flip panel 82 are in the same plane, the magnetic steel 1 gradually moves forward to the outer baffle 11 and the screening conveyor track 6 through the guide member 83, such as Fig. 9 As shown, and due to the vibration, it continues to move forward. As the inclination angle of the outer baffle 11 gradually increases, and because the width of the baffle surface of the outer baffle 11 is longer than the width of the screening conveying track 6, the curved surface of the magnetic steel 1 is gradually lifted and tilted in contact with the outer baffle 11, as shown in FIG. Fig.10 As shown, until the outer baffle plate 11 is in a vertical position, the magnetic steel 1 is tilted and attached to the inner baffle plate 10, as shown in FIG. Fig.11 As shown, the plane of the magnetic steel 1 contacts the inner baffle 10 and continues to be transported;

[0087] S4. Facing judgment rejection: When the magnetic steel 1 is transported forward on the screening conveying track 6 to the judgment vibrator 91, the magnetic steel 1 with a flat surface in contact with the inner baffle 10 continues to be transported forward on the screening conveying track 6. If there is still a magnetic steel 1 with a curved surface in contact with the inner baffle 10, the magnetic steel 1 is judged to be vibrated and ejected from the screening conveying track 6 by the vibrator 91 due to the unstable curved surface contact. Fig.13 As shown, it falls on the top surface of the vibration plate body between the inner ring frame 3 and the outer ring frame 4;

[0088] S5. Transporting outward: The magnetic steel 1 that falls on the top surface of the vibration plate body between the inner ring frame 3 and the outer ring frame 4 is transported to the feeding opening 14 due to the vibration of the vibration plate, and enters the inner ring frame 3 to continue vibrating and feeding, and repeats steps S1-S4; the magnetic steel 1 that contacts the inner baffle 10 with a flat surface is transported on the screening conveying track 6 until the inclination angle of the inner baffle 10 is gradually reduced to a horizontal level, such as Fig.14 As shown, the magnetic steel 1 is on the inner baffle plate 10 with the curved surface facing upward.

10. A screening method for a screening and feeding device containing curved magnetic steel according to any one of claims 1 to 9, characterized in that: The specific steps include: S1. Vibration loading: The magnetic steels to be screened are placed on the main body of the vibration plate and located in the inner ring frame. The magnetic steels are gradually transported upward through the spiral loading plate due to the vibration of the vibration plate. The relatively large flat or curved surface of the magnetic steels is transported by contacting the spiral loading plate due to vibration. Since the inner side of the spiral loading plate is higher than the outer side, the magnetic steels are transported outside on the spiral loading plate, that is, close to the inner ring frame, until they are transported to the top of the spiral loading plate. S2. Sorting and conveying: The magnetic steels conveyed to the top of the spiral feeding plate enter the screening and conveying track through the feeding slot one by one. Since the end of the inner baffle plate close to the spiral feeding plate and the upper end of the spiral feeding plate are in the same plane, the plane or curved surface of the magnetic steel just entering the screening and conveying track is located on the screening and conveying track and the inner baffle plate. With the vibration movement, the inclination angle of the inner baffle plate gradually increases. Since the width of the baffle surface of the inner baffle plate is longer than the width of the screening and conveying track, the plane or curved surface of the magnetic steel gradually moves with the inclination of the inner baffle plate, and the side surface between the plane and curved surface of the magnetic steel contacts the screening and conveying track and moves; S3. Face judgment flip: when the magnetic steel is transported to the position of the corresponding flip vibrator on the screening conveyor track; S31. If the side surface close to the inner baffle is flat and in full contact with the inner baffle, due to the gravity of the magnet itself, the vibration of the flip vibrator is not enough to make the magnet slide out of the screening conveyor track, and the magnet is still transported forward along the inner baffle in the screening conveyor track; S32. If the side surface close to the inner baffle is a curved surface, the contact area with the inner baffle is small and the contact is unstable. Under the dual vibration of the vibration plate body and the flip vibrator, the magnet is vibrated and bounced up, and slides out of the screening conveyor track and slides onto the flip panel. The curved surface of the magnet on the flip panel faces downward and the flat surface faces upward. On the flip panel, it continues to move forward due to the vibration of the vibration plate body. S33. Because the end of the outer baffle plate in front of the flap plate is in the same plane as the flap plate, the magnetic steel gradually moves forward onto the outer baffle plate and the screening conveying track through the guidance of the guide member, and continues to move forward due to vibration. As the inclination angle of the outer baffle plate gradually increases, and because the width of the baffle surface of the outer baffle plate is longer than the width of the screening conveying track, the curved surface of the magnetic steel is gradually lifted and tilted in contact with the outer baffle plate until the outer baffle plate is in a vertical position, and the magnetic steel falls over and fits the inner baffle plate, so that the flat surface of the magnetic steel contacts the inner baffle plate and continues to be transported; S4. Facing judgment rejection: When the magnet is transported forward to the judgment vibrator on the screening conveyor track, the magnet with a flat surface in contact with the inner baffle continues to be transported forward on the screening conveyor track. If there is still a magnet with a curved surface in contact with the inner baffle, the judged vibrator will vibrate and slide out of the screening conveyor track due to the unstable curved surface contact, and fall on the top surface of the vibration plate body between the inner ring frame and the outer ring frame; S5. Outward transportation: The magnets that fall onto the top surface of the vibration disk body between the inner ring frame and the outer ring frame are transported to the loading opening due to the vibration of the vibration disk, and enter the inner ring frame to continue vibrating and loading, and steps S1-S4 are repeated; the magnets that are in flat contact with the inner baffle are transported on the screening and conveying track until the inclination angle of the inner baffle is gradually reduced to a horizontal level, and the curved surface of the magnets on the inner baffle faces upward.
