Description

Technical Field

[0001] This invention relates to the field of neodymium iron boron (NdFeB) conveying technology, specifically to a vibrating feeding mechanism and a NdFeB weighing and sorting device. Background Technology

[0002] Surface mount neodymium iron boron (NdFeB) products on the motor rotor can affect the rotor's balance. This is mainly because NdFeB products have manufacturing tolerances and slight differences in size, which in turn leads to variations in individual product weights. Ultimately, this affects the vibration and noise during motor operation.

[0003] Therefore, neodymium iron boron magnets used in motor rotors need to be weighed and classified according to the weight of individual neodymium iron boron products. Currently, they are transferred to a weighing device manually, which is inefficient and prone to errors in weight classification. Chinese patent CN219383957U discloses a clamping device for neodymium iron boron magnet production, which can be used for clamping and feeding neodymium iron boron magnets during weighing. However, the above device can only clamp and transfer sorted neodymium iron boron magnets and cannot feed unstacked neodymium iron boron magnets.

[0004] Therefore, the problem in the existing technology is: how to sort and feed the unstacked NdFeB magnets. Summary of the Invention

[0005] This invention provides a vibratory feeding mechanism and a neodymium iron boron weighing and sorting device, which at least solves the problem of sorting and feeding unstacked neodymium iron boron.

[0006] The technical solution used in this invention is as follows:

[0007] The first aspect of this application discloses a vibratory feeding mechanism, including a stacking cabinet and a stacking unit and a transfer unit disposed on the stacking cabinet. A feeding rack is horizontally arranged above the stacking unit, and a funnel-shaped feeding hopper is provided inside the feeding rack. The lower opening of the feeding hopper is directly opposite the feeding side of the stacking unit. A vibratory feeding unit is provided on the side of the stacking cabinet. The stacking unit is used to sort NdFeB magnets and output rows of NdFeB magnets. The stacking unit includes a stacking base disposed opposite to each other and a receiving tray disposed on the stacking base. The receiving tray has a disc-shaped structure. A brush motor is mounted on the upper side of the receiving tray via a crossbeam plate. The motor shaft of the sweeping motor extends downward to form a crossbeam plate, which is fixed to the upper side of the brushing rubber plate. The lower side of the brushing rubber plate contacts the bottom of the receiving tray. The lower side of the receiving tray is provided with a discharge groove and a push plate groove with a semi-circular cross section. A discharge plate is slidably fitted inside the discharge groove. A discharge push rod is fixed to the side of the stacking base through a base connecting plate. The push head of the discharge push rod is fixed to the side of the discharge plate through the discharge push plate. A turntable groove is opened on the upper side of the discharge plate, and a discharge turntable is rotatably fitted inside the turntable groove through a rotating shaft. Several rotating plate slots are opened on the discharge turntable, and insert plates are inserted into the rotating plate slots. The insert plates are provided with receiving grooves.

[0008] Furthermore, a zigzag-shaped upper top plate is provided between the stacking bases; a top wheel frame is provided on the lower side of the discharge plate, and an upper supporting column is slidably fitted on the top wheel frame. An upper supporting magnet is provided on the upper side of the upper supporting column, and an upper supporting roller is provided on the lower side of the upper supporting column. The upper supporting roller is in rolling cooperation with the upper top plate; an anti-detachment plate is provided on the upper supporting column, and an upper supporting spring is fitted on the upper supporting column. The upper supporting spring is locked between the top wheel frame and the anti-detachment plate; an upper top channel is opened on the discharge plate, and the position of the upper top channel corresponds to the plug-in plate in the receiving tray.

[0009] Furthermore, the plug-in plate includes an outer frame with a ring structure and an inner top plate that fits inside the outer frame. The outer frame is plugged into the turntable slot of the discharge turntable. The upper side of the inner top plate has a receiving protrusion, and the upper side of the outer frame has a corresponding receiving groove. The receiving protrusion and the receiving groove together form a receiving space for receiving neodymium iron boron. A first combination magnet is provided on both sides of the receiving protrusion, and a second combination magnet corresponding to the first combination magnet is provided on the inner side of the outer frame. The lower side of the inner top plate has a magnetic attraction part corresponding to the upper supporting magnet. The attraction force between the upper supporting magnet and the magnetic attraction part is less than the elastic force of the upper supporting spring.

[0010] Furthermore, the transfer unit is located on the side of the stacking unit; the transfer unit includes a transfer robotic arm and a transfer bracket located at the output end of the transfer robotic arm. A transfer fixing frame is provided on the lower side of the transfer bracket, and a sorting shaft is rotatably fitted on the transfer fixing frame. A sorting motor is provided on the side of the transfer fixing frame, and the sorting motor is used to drive the sorting shaft to rotate; cylindrical first sorting blocks, second sorting blocks and third sorting blocks are fixed on the sorting shaft.

[0011] Furthermore, the first sorting block has two semi-annular guide grooves, which are connected by an oblique guide groove to form a ring; the second sorting block has a circular guide groove; the guide groove on the third sorting block is the same as the guide groove on the first sorting block; a suction cup groove is provided on the lower side of the transfer fixing frame, and a suction cup slider is slidably fitted in the suction cup groove. A guide post is provided on the upper side of the suction cup slider, and the guide post is slidably fitted in the guide groove. A mounting frame is provided on the lower side of the suction cup slider, and a gas suction cup for adsorbing neodymium iron boron is provided on the mounting frame.

[0012] Furthermore, the vibratory feeding unit includes a vibratory support and a vibratory plate mounted on the vibratory support, with the output end of the vibratory plate facing the upper side of the feeding hopper.

[0013] The second aspect of this application provides a neodymium iron boron weighing and sorting device, including the vibrating feeding mechanism of the above embodiment, and also including a weighing cabinet; the weighing cabinet has an L-shaped structure, and three electronic balances are fixed on the weighing cabinet via a weighing platform, the electronic balances being used to weigh three neodymium iron borons arranged in a row separately.

[0014] Furthermore, an L-shaped positioning plate is provided on the right side of the weighing cabinet, and rows of material boxes are secured between the positioning plates.

[0015] Furthermore, dust covers are installed above the weighing cabinet and the stacking cabinet. These dust covers are used to cover the electronic balance, the material box, and the transfer unit.

[0016] The beneficial effects achieved by this invention are as follows: Based on the shape and size of the NdFeB to be processed, the discharge turntable is manually rotated to rotate the appropriate receiving groove into the receiving tray, completing the adjustment process. After starting the equipment, the vibrating feeding unit transfers the NdFeB to be processed to the feeding hopper at a uniform speed. Subsequently, the stacking unit is activated, and the brushing motor on the crossbeam drives the brushing rubber plate to rotate 360 ​​degrees around the center of the receiving tray. The lower side of the brushing rubber plate is in close contact with the bottom of the receiving tray, pushing the loose NdFeB to move during rotation, causing three NdFeB pieces to embed into the receiving groove, forming evenly spaced rows of stacked pieces. The remaining NdFeBs that did not enter the receiving tank are pushed back to the initial feeding area of ​​the receiving tray by the continuous pushing of the brushing rubber plate to avoid interfering with subsequent discharge; the discharge push rod on the base connecting plate on the side of the stacking base extends, and its push head drives the discharge plate to slide along the discharge groove of the receiving tray through the discharge push plate; the discharge turntable on the discharge plate moves synchronously with the discharge plate. When the discharge plate slides completely out of the outside of the receiving tray, the three NdFeBs in a row move out of the receiving tray range along with the receiving groove. At this time, the transfer unit is activated to grab the three NdFeBs in a row and transfer them to the electronic balance to complete the subsequent weighing operation. Attached Figure Description

[0033] To facilitate understanding of the present invention by those skilled in the art, specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood through the specific circumstances.

[0035] like Figure 1-2 As shown, the present invention provides a vibratory feeding mechanism, including a stacking cabinet 1 and a stacking unit and a transfer unit disposed on the stacking cabinet 1. A feeding rack 2 is horizontally arranged above the stacking unit, and a funnel-shaped feeding hopper 3 is provided inside the feeding rack 2. The lower opening of the feeding hopper 3 is directly opposite to the feeding side of the stacking unit. The vibratory feeding unit is provided on the side of the stacking cabinet 1. The vibratory feeding unit is used to transfer the NdFeB to be sorted to the feeding hopper 3 at a uniform speed. The vibratory feeding unit includes a vibrating support 4 and a vibrating plate 5 disposed on the vibrating support 4. The output end of the vibrating plate 5 is directly opposite to the upper side of the feeding hopper 3. The feeding speed is controlled by the vibrating plate 5 to perform automatic feeding. The stacking unit is used to sort the NdFeB and output rows of NdFeB. The transfer unit is disposed on the side of the stacking unit and is used to transfer the rows of NdFeB output by the stacking unit.

[0036] like Figure 3 As shown, the stacking unit includes a stacking base 6 and a receiving tray 7 disposed on the stacking base 6. The receiving tray 7 has a disc-shaped structure. A brushing motor 9 is mounted on the upper side of the receiving tray 7 via a crossbeam plate 8. The motor shaft of the brushing motor 9 extends downward from the crossbeam plate 8 and is fixed to the upper side of the brushing rubber plate 10. The lower side of the brushing rubber plate 10 contacts the bottom of the receiving tray 7. Figure 4 As shown, the receiving tray 7 has a semi-circular cross-section discharge groove 11 and a push plate groove 12 on its lower side; the discharge groove 11 is connected to the bottom of the receiving tray 7, and a rectangular cross-section discharge plate 13 is slidably fitted inside the discharge groove 11; the stacking base 6 has a base connecting plate 14 on its side, and a discharge push rod 15 (either a pneumatic cylinder or a hydraulic cylinder) is provided on the base connecting plate 14; the push head of the discharge push rod 15 is fixed to the side of the discharge plate 13 through the discharge push plate 16; the discharge push rod 15 is used to drive the discharge plate. 13 Sliding; A turntable groove 17 is provided on the upper side of the discharge plate 13, and a discharge turntable 18 is rotatably fitted in the turntable groove 17 via a rotating shaft; Four rotating plate slots 19 are provided on the discharge turntable 18, and plug-in plates 20 are inserted into the rotating plate slots 19. The plug-in plates 20 are provided with receiving grooves 21 of different cross sections, and the receiving grooves 21 are arranged in groups of three at intervals; The receiving grooves 21 are adapted to products of different shapes and sizes, such as irregular products, tile-shaped products, and conventional round and square products.

[0037] like Figure 5As shown, according to the shape and size of the NdFeB to be processed, the discharge turntable 18 is manually rotated so that the matching receiving groove 21 rotates into the receiving tray 7, completing the adaptation adjustment. After the equipment is started, the vibrating feeding unit transfers the NdFeB to be processed to the feeding hopper 3 at a uniform speed. The material falls into the disc-shaped receiving tray 7 of the stacking unit through the lower opening of the feeding hopper 3 (concentrated on the side of the non-discharge plate 13). Then the stacking unit is started. The brushing motor 9 on the crossbeam plate 8 drives the motor shaft to rotate the brushing rubber plate 10 360 degrees around the center of the receiving tray 7. The lower side of the brushing rubber plate 10 is in close contact with the bottom of the receiving tray 7. During the rotation, it pushes the loose NdFeB to move, so that three of the NdFeB are embedded in the receiving groove 21, forming a uniformly spaced row of stacked pieces. The rest do not enter the receiving groove 21. The neodymium iron boron (NdFeB) metals are continuously pushed back to the initial feeding area of ​​the receiving tray 7 by the brushing plate 10 to avoid interfering with subsequent discharge. The discharge push rod 15 on the base connecting plate 14 on the side of the stacking base 6 extends, and its push head drives the discharge plate 13 to slide along the discharge groove 11 of the receiving tray 7 through the discharge push plate 16. The discharge turntable 18 on the discharge plate 13 moves synchronously with the discharge plate 13. When the discharge plate 13 slides completely out of the outside of the receiving tray 7, the three NdFeB metals in a row move out of the receiving tray 7 range along with the receiving groove 21. At this time, the transfer unit is activated to grab the three NdFeB metals in a row and transfer them to the electronic balance 52 to complete the subsequent weighing operation. The discharge push rod 15 retracts, driving the discharge plate 13 to reset, and the discharge turntable 18 rotates back to the initial position, waiting for the next round of sorting cycle.

[0038] It should be noted that the discharge turntable 18 has four rotating plate slots 19 evenly distributed around its circumference. By manually rotating the discharge turntable 18, the plug-in plate 20 adapted to the current shape and size of the NdFeB can be switched to the working position, achieving rapid compatibility with materials of different specifications. The plug-in mating structure between the plug-in plate 20 and the rotating plate slot 19 means that when the receiving groove 21 is worn or its specifications change, only the plug-in plate 20 needs to be replaced, without replacing the entire discharge turntable 18, thus reducing maintenance costs. The receiving groove 21 adopts a structure of three groups spaced apart, which can simultaneously complete the equidistant stacking of three NdFeB pieces in a single sorting, improving sorting efficiency. Overall, this mechanism realizes the automated sorting of NdFeB from scattered input to row-spaced output through the linkage between the uniform feeding of the vibrating feeding unit, the rotating sorting of the brushing plate 10, the modular quick-change of the discharge turntable 18, and the linear pushing of the discharge pusher plate 16.

[0039] The transfer unit is used to transfer rows of NdFeB magnets. The transfer unit can be either a clamping type or an adsorption type. When the transfer unit is a clamping type, the NdFeB products are housed in the receiving groove 21, making it inconvenient for the transfer unit to clamp them. To solve this problem, such as... Figure 6-7As shown, a zigzag-shaped upper top plate 22 is provided between the stacking bases 6; a U-shaped top wheel frame 23 is provided on the lower side of the discharge plate 13, and four square-section upper driven columns 24 are slidably fitted on the top wheel frame 23. An upper supporting magnet 25 is provided on the upper side of the upper driven column 24, and an upper supporting roller 26 is provided on the lower side of the upper driven column 24. The upper supporting roller 26 rolls with the upper top plate 22; an anti-detachment plate 27 is provided on the upper driven column 24, and an upper supporting spring 28 is sleeved on the upper driven column. The upper supporting spring 28 is locked between the top wheel frame 23 and the anti-detachment plate 27, and is used to force the upper supporting roller 26 to contact the upper top plate 22; an upper top channel 29 is opened on the discharge plate 13, and the position of the upper top channel 29 corresponds to the insertion plate 20 in the receiving tray 7; as shown Figure 8 As shown, one embodiment of the plug-in plate 20 includes an outer frame 30 with an annular structure and an inner top plate 31 that fits inside the outer frame 30. The outer frame 30 is plugged into the turntable slot 19 of the discharge turntable 18. The upper side of the inner top plate 31 has a receiving protrusion 32, and the upper side of the outer frame 30 has a corresponding receiving groove 33. The receiving protrusion 32 and the receiving groove 33 together form a receiving space for receiving neodymium iron boron. The two sides of the receiving protrusion 32 are provided with a first combination magnet 34, and the inner side of the outer frame 30 is provided with a second combination magnet 35 corresponding to the first combination magnet 34. The inner top plate 31 is plugged into the inner side of the outer frame 30, and the first combination magnet 34 and the second combination magnet 35 are magnetically attracted to form a whole. The lower side of the inner top plate 31 has a magnetic attraction part corresponding to the upper support magnet 25. The attraction force between the upper support magnet 25 and the magnetic attraction part is less than the elastic force of the upper support spring 28.

[0040] like Figure 9 As shown, when the discharge plate 13 slides outward along the discharge groove 11 of the receiving tray 7 under the drive of the discharge push rod 15, the upper push driven column 24 in the top wheel frame 23 on the lower side of the discharge plate 13 moves synchronously with the discharge plate 13, and the upper support roller 26 at its bottom end rolls along the zigzag surface of the upper top plate 22; when the upper support roller 26 rolls to the rising section of the upper top plate 22, the upper push driven column 24 overcomes the elastic force of the upper support spring 28 and slides upward, and the upper support magnet 25 at its upper end is magnetically attracted to the inner top plate 31 through the upper push channel 29 on the discharge plate 13 to form a whole, further... The step drive causes the inner top plate 31 to rise relative to the outer frame 30, lifting the NdFeB product to protrude from the upper surface of the outer frame 30. The NdFeB is in an exposed position that is easy to clamp. The clamping transfer unit can grab three NdFeB pieces and transfer them to the electronic balance 52. When the discharge plate 13 retracts, the reset force of the upper support spring 28 causes the upper support driven column 24 to slide down, and the upper support magnet 25 separates from the inner top plate 31. The upper support driven column 24 and the inner top plate 31 are normally in a separated state, and the discharge turntable 18 can freely adjust the matching receiving groove 21 without interference.

[0041] The transfer unit transfers the three NdFeB blocks arranged in a row from the stacking unit to the electronic balance 52 for weighing. If the quality meets the acceptable range, it transfers them to the acceptable material box 54; if they do not meet the acceptable range, it first needs to be moved above the acceptable material box 54 to release the acceptable NdFeB blocks, and then it needs to be moved above the unacceptable material box 54 to release the unacceptable NdFeB blocks again. Whenever there are unacceptable NdFeB blocks, two movement and positioning operations are required. To solve this problem... Figure 10 As shown, the transfer unit includes a transfer robotic arm 36 and a transfer bracket 37 located at the output end of the transfer robotic arm 36. A transfer fixing frame 38 is provided on the lower side of the transfer bracket 37. A sorting shaft 39 is rotatably fitted on the transfer fixing frame 38. A sorting motor 40 is provided on the side of the transfer fixing frame 38, and the sorting motor 40 drives the sorting shaft 39 to rotate. Cylindrical first sorting blocks 41, second sorting blocks 42, and third sorting blocks 43 are fixed on the sorting shaft 39. Figure 11-12 As shown, the first sorting block 41 is provided with two semi-annular guide grooves 44, which are connected by an oblique guide groove 44 to form a ring; the second sorting block 42 is provided with an annular guide groove 44; the guide groove 44 on the third sorting block 43 is the same as the guide groove 44 on the first sorting block 41; the lower side of the transfer fixing frame 38 is provided with a suction cup groove 45, and three suction cup sliders 46 are slidably fitted in the suction cup groove 45. The upper side of the suction cup sliders 46 is provided with a guide post 47, which is slidably fitted in the guide groove 44. The lower side of the suction cup sliders 46 is provided with a mounting frame 48, and the mounting frame 48 is provided with a gas suction cup 49 for adsorbing neodymium iron boron.

[0042] like Figure 13 As shown, the three air suction cups 49 are located in the middle position under normal conditions. When the transfer robotic arm 36 drives the air suction cups 49 to pick up the three NdFeBs arranged in a row from the stacking unit, they are first moved to the electronic balance 52 for weighing. The qualified status of each NdFeB is determined according to the weighing result. Then the air suction cups 49 pick up the three NdFeBs again from the electronic balance 52.

[0043] If all three NdFeB magnets are qualified, the transfer robotic arm 36 moves the air suction cup 49 above the qualified material box 54, and then the air suction cup 49 is released, and the three NdFeB magnets fall into the qualified material box 54 at the same time; the classification and release of the three NdFeB magnets are completed in one movement.

[0044] If there are defective NdFeB magnets on the left and right sides (e.g., only the middle piece is qualified while both sides are defective, or one side is qualified while the other is defective), during the process of the transfer robotic arm 36 moving the air suction cup 49 above the qualified material box 54, the sorting motor 40 drives the sorting shaft 39 to rotate. Driven by the guide groove 44 of the first sorting block 41 or the third sorting block 43, the suction cup slider 46 corresponding to the defective NdFeB magnet will shift outward along the suction cup groove 45; for example, the NdFeB magnets on the right side are defective ( Figure 13The guide groove 44 of the third classification block 43 drives the right air suction cup 49 to shift outward and move to the corresponding position of the unqualified material box 54. The middle and left air suction cups 49 remain in their original positions. The middle and left air suction cups 49 release qualified NdFeB, and the right air suction cup 49 releases unqualified NdFeB. The classification and release of the three NdFeB blocks are completed in one movement.

[0045] If there are any defective NdFeB pieces in the middle, the transfer robotic arm 36 moves the air suction cup 49 above the qualified material box 54, and then the air suction cups 49 on both sides are released, and the three NdFeB pieces fall into the qualified material box 54 at the same time; the transfer robotic arm 36 moves the air suction cup 49 above the defective material box 54 again, and the air suction cup 49 in the middle releases the defective NdFeB pieces; this situation is the same as the conventional method, and two movements are required to complete the classification and release of the three NdFeB pieces.

[0046] It should also be noted that the first classification block 41 and the third classification block 43 adopt a structural design in which two semi-annular guide grooves 44 are connected to form a ring through the oblique guide grooves 44. This design can convert the rotational motion of the classification axis 39 into the linear displacement of the suction cup slider 46, so that the dynamic adjustment of the suction cup position can be completed during the movement of the robotic arm. This optimizes the classification action that originally required two round trips into a relative displacement composite action under one positioning, reducing the movement path and positioning time of the robotic arm.

[0047] like Figure 1 , Figure 14-15 As shown, the second aspect of this application proposes a neodymium iron boron (NdFeB) weighing and sorting device, including the vibrating feeding mechanism of the above embodiment, and also a weighing cabinet 50; the weighing cabinet 50 has an L-shaped structure, and three electronic balances 52 are fixed on the weighing cabinet 50 via a weighing platform 51. The electronic balances 52 are used to weigh the three NdFeBs arranged in a row separately; an L-shaped positioning plate 53 is provided on the right side of the weighing cabinet 50, and rows of material boxes 54 are locked between the positioning plates 53; as shown... Figure 1 As shown, a dust cover 55 is provided above the weighing cabinet 50 and the stacking cabinet 1. The dust cover 55 is used to cover the electronic balance 52, the material box 54 and the transfer unit. If the electronic balance 52 and the transfer unit are installed in the same cabinet, the vibration of the transfer unit will be directly transmitted to the electronic balance 52 through the cabinet structure, causing the electronic balance 52 to vibrate and resonate slightly, resulting in fluctuations in the weighing data and affecting the accuracy of quality judgment. In this application, the electronic balance 52 and the transfer unit are placed on separate cabinets. The two are isolated from each other by the split cabinet structure, which improves the weighing accuracy.

[0048] Unless otherwise specified, the above methods of fixing all use common technical means employed by industry professionals, such as welding, nesting, or threaded fixing.
