Description

A magnet pressing device for rotors of new energy motors Technical Field

[0001] This invention relates to magnet press-fitting equipment technology, specifically a magnet press-fitting equipment for new energy motor rotors. Background Technology

[0002] The rotor is a key component of an electric motor, and its manufacturing process directly affects the overall quality of the motor. During rotor assembly, the insertion of magnets is a complex and crucial step, typically accomplished using a magnet insertion machine. However, existing magnet insertion machines, due to fitting issues, have a probability of failing to insert magnets correctly into the magnet slots, leading to assembly errors.

[0003] Currently, most production lines do not have a magnet inspection process. This means that if a magnet is missing, it will be difficult to remedy the situation after subsequent processes are completed, which may eventually lead to the scrapping of the entire workpiece. This not only increases the scrap rate but also causes significant economic losses. Summary of the Invention

[0004] The purpose of this invention is to provide a magnet pressing device for rotors of new energy motors, thereby solving the problems mentioned in the background section. To achieve the above objective, this invention provides the following technical solution.

[0006] Press-fitting mechanism;

[0007] A movable base, with a servo motor at its bottom, is used to cooperate with a pressing mechanism to press the magnet into the rotor magnet slot.

[0008] A rotor mounting base is fixedly connected to the end of the internal shaft of a servo motor.

[0009] The testing organization includes:

[0010] An air pump has a housing at its bottom, the top of which is connected to the air outlet. Several connecting pipes are connected to the bottom of the housing, and a contact element is located at the bottom of each connecting pipe. The top and bottom of each connecting pipe are connected to the housing and the contact element, respectively. One side of the contact element is open and fits against the side wall of a magnet. An L-shaped tube is connected to the top side wall of the connecting pipe, and the top of the L-shaped tube is open. A hollow ball is located within a straight section of the L-shaped tube, and a triggering mechanism is located on the straight section. The top of the L-shaped tube is trumpet-shaped.

[0011] The ejection mechanism is located on the upper side of the rotor mounting base and is used to cooperate with the detection mechanism to eject the defective magnet from the rotor magnet slot.

[0012] Preferably, the contact member is provided with a partition, which divides the contact member into an air outlet chamber and an air inlet chamber.

[0013] The magnet pressing equipment for new energy motor rotors also includes an air pipe, the lower end of which passes through a contact piece and is connected to the air inlet chamber, the upper end of which passes through an L-shaped pipe, and the top end of which is connected to an air bladder.

[0014] Preferably, rubber strips are attached to the edge of the opening end of the contact element and the edge of the partition.

[0015] Preferably, the triggering mechanism includes: a connecting ear, the connecting ear being fixedly connected to the inner wall of the straight section of the L-shaped tube, two sets of the connecting ears being symmetrically arranged, the top of the connecting ear being arc-shaped, an electrode plate being provided on the upper surface of the connecting ear, and the hollow sphere being made of conductive metal.

[0016] Preferably, the open end of the L-shaped tube is provided with a barrier mesh.

[0017] Preferably, the ejection mechanism includes: a rotating disk, on which an electric cylinder is mounted, the outer shell of the electric cylinder being fixedly connected to the rotating disk, and a push plate being fixedly connected to the end of the internal telescopic rod of the electric cylinder, the push plate being used to cooperate with the electric cylinder to eject the magnet from the rotor magnet slot.

[0018] Preferably, an arc-shaped disk is provided on one side of the detection mechanism, an electric cylinder two is provided on the top of the arc-shaped disk, a fixing frame is fixedly connected to the outer shell of the electric cylinder two, the bottom of the arc-shaped disk is fixedly connected to the outer shell of the air pump, and the air pump is provided in several sets.

[0019] Preferably, the rotating disk is rotatably connected to the internal telescopic rod of the electric cylinder two, the inner wall of the rotating disk is provided with teeth arranged in a circumferential array, the surface of the arc-shaped disk is provided with a servo motor two, the outer shell of the servo motor two is fixedly connected to the arc-shaped disk, and the end of the internal rotating shaft of the servo motor two is fixedly connected with a gear, which meshes with the teeth on the inner wall of the rotating disk.

[0020] Preferably, the rotor mounting base has through slots arranged in a circumferential array, and the number of through slots is equal to the number of slots in the rotor magnet.

[0021] Preferably, a placement tray is fixedly connected to the top of the movable base, the placement tray is used to place magnets, and a plug plate is slidably connected to one side of the placement tray.

[0022] The present invention has at least the following beneficial effects:

[0023] 1. During magnet inspection, the rotor mounting base moves the rotor below the inspection mechanism. The contact at the bottom of the connecting pipe is inserted into the magnet slot, and the air pump supplies air. If the magnet's edge is undamaged, the air pushes the hollow ball upwards, causing it to float at the top. If the magnet's edge is damaged, gas leaks from the crack, preventing the hollow ball from moving upwards. The trigger mechanism then marks the damage location and automatically detects the magnet's edge damage. Using gas to drive the hollow ball reduces wear.

[0024] 2. After the inspection is completed, the contact part exits the magnet slot, and the ejection mechanism rotates to the position marked with the defective magnet slot, and ejects the damaged magnet out of the magnet slot. With this design, the integrity of the magnet can be checked after the magnet is installed in the magnet slot, thereby avoiding the whole workpiece being scrapped after being directly installed into the motor, and reducing the scrap rate to a certain extent.

[0025] 3. A baffle is added inside the contact element. When the contact element moves to the damaged part of the magnet, gas enters the air intake chamber through the connecting pipe, and some gas leaks out from the rupture. The gas enters the airbag through the air pipe, inflating the airbag and reducing the size of the L-shaped air intake, thus decreasing the air intake volume. The reduced thrust causes the hollow ball to fall rapidly and detach from the triggering mechanism, quickly triggering the mechanism's reaction time.

[0026] 4. When the hollow sphere falls, the connecting lugs will prevent it from falling further. If it is damaged, the gas thrust will be insufficient to push the hollow sphere upward. The hollow sphere, made of conductive metal, will contact the electrode plates on both sides of the connecting lugs, thus connecting the circuit and indicating that the magnet in the magnet slot is damaged. The circuit connection enables rapid judgment and improves detection efficiency. Attached Figure Description

Specific implementation manner

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0039] To better understand the present invention, the existing magnetic steel press-fitting equipment will be briefly introduced first. First, the rotor is fixed on a special fixing seat to ensure that it will not move during the press-fitting process. The magnetic steel is usually placed on a fixture or a supporting device to ensure the accurate position of the magnetic steel so as to accurately press it into the magnetic steel groove of the rotor. The press head of the press-fitting equipment, for example, driven by a hydraulic cylinder or a servo motor, will move along a predetermined path and gradually approach the magnetic steel. When the press head touches the magnetic steel, it will continue to apply pressure to slowly but forcefully push the magnetic steel into the magnetic steel groove of the rotor. If manual installation is adopted, the rotor is placed on a plane and fixed, and the magnetic steel is pressed by fingers to sequentially press the magnetic steel into the magnetic steel groove. The side wall and edge of the magnetic steel are usually the weakest points and may generate micro-cracks during the manufacturing process. Therefore, during use, when press-fitting, clamping or fixing, the edge part may be subjected to greater concentrated stress and thus break. And when the magnetic steel is pressed into the magnetic steel groove of the rotor, it is impossible to directly observe whether the edge of the magnetic steel is broken.

[0040] The solution of the present application is to detect the edge of the magnetic steel after all the magnetic steels are pressed into the magnetic steel groove of the rotor by the press-fitting equipment. When a damaged magnetic steel is found, the magnetic steel groove where it is located is marked, and it is pushed out and re-pressed until the product is qualified. This process is completed before the press-fitted rotor is put into the motor, avoiding the problem that it is difficult to remedy after being put into the motor.

[0041] Example 1: Please refer to Figures 1-10. A surface-mount rotor magnet pressing device for a new energy motor includes:

[0042] Pressing mechanism 10, the pressing mechanism 10 includes:

[0043] The workbench has pressing tables fixedly connected to both sides. A magnet loading mechanism is installed inside the pressing table. An electric cylinder three is fixedly connected to the pressing table. A pressure head is fixedly connected to the end of the telescopic rod inside the electric cylinder three. The electric cylinder three, in conjunction with the magnet loading structure, can press the magnet into the rotor magnet slot. All of the above are existing technologies and will not be elaborated on here.

[0044] The mobile base 20 has a servo motor 22 at its bottom. The housing of the servo motor 22 is fixedly connected to the bottom of the mobile base 20. The mobile base 20 is used to cooperate with the pressing mechanism 10 to press the magnet into the rotor magnet slot.

[0045] Rotor mounting base 21, wherein the rotor mounting base 21 is fixedly connected to the end of the rotating shaft inside the servo motor 22;

[0046] It should be noted that by placing the rotor on the rotor mounting base 21, it is prevented from shifting during the pressing and testing process. The rotor mounting base 21 with the rotor is moved to the bottom of the pressing table via the movable base 20. The pressure head at the bottom of the electric cylinder presses the magnet into the rotor magnet groove. The movable base 20 then moves the rotor mounting base 21 with the rotor to the bottom of the testing mechanism 30.

[0047] Testing mechanism 30, the testing mechanism 30 includes:

[0048] An air pump 31 has a housing 32 at its bottom. The top of the housing 32 is connected to the air outlet of the air pump 31. Several connecting pipes 33 are connected to the bottom of the housing 32. A contact 34 is provided at the bottom of each connecting pipe 33. The top and bottom of each connecting pipe 33 are connected to the housing 32 and the contact 34, respectively. One side of the contact 34 is open and fits against the side wall of the magnet. An L-shaped tube 35 is connected to the top side wall of the connecting pipe 33. The top of the L-shaped tube 35 is open. A hollow ball 36 is provided in the straight section of the L-shaped tube 35. A triggering mechanism 37 is provided on the straight section of the L-shaped tube 35. The top of the L-shaped tube 35 is trumpet-shaped.

[0049] It should be noted that after moving the rotor fixing seat 21 with the inserted magnet to the lower side of the detection mechanism 30, the contact 34 at the bottom of the connecting pipe 33 is inserted along the gap between the magnet and the magnet groove, with the open end of the contact 34 facing the edge of the magnet. When the contact 34 is completely submerged in the magnet groove, the air pump 31 starts to supply air. If the edge of the magnet is not damaged after insertion, the open end of the contact 34 will be sealed to the edge of the magnet. Therefore, the air will reach the position of the hollow ball 36 through the L-shaped pipe 35. When the thrust generated by the air is greater than the weight of the hollow ball 36, the hollow ball 36 moves upward along the L-shaped pipe 35. When the hollow ball 36 reaches the top of the L-shaped pipe 35, the opening of the L-shaped pipe 35 increases, and the gas is released from the edge of the hollow ball 36. Therefore, the hollow ball 36 will be in a state of up and down floating at the top. If the edge of the magnet is damaged during insertion into the magnet slot, when the connecting pipe 33 drives the contact 34 to move along the edge to the damaged position, a gap will be generated at the open end of the contact 34. The gas generated by the air pump 31 will leak out from the crack between the contact 34 and the magnet. At this time, the amount of gas entering the L-shaped pipe 35 will be reduced, and the thrust generated by the gas will not be enough to push the hollow ball 36 upward. When the hollow ball 36 contacts the trigger mechanism 37 on the L-shaped pipe 35, the trigger mechanism 37 will cooperate with the terminal to mark the magnet slot at this point.

[0050] The ejection mechanism 40 is disposed on the upper side of the rotor fixing seat 21. The ejection mechanism 40 is used to cooperate with the detection mechanism 30 to eject the defective magnet from the rotor magnet slot.

[0051] It should be noted that after the inspection mechanism 30 completes the inspection, the contact 34 exits the magnet slot, and the ejection mechanism 40 rotates to the position marked as the damaged magnet slot, thereby ejecting the damaged magnet out of the slot. This design allows for the inspection of the magnet's integrity after it has been installed in the slot, thus avoiding the complete scrapping of the workpiece after direct installation into the motor and reducing the scrap rate to some extent.

[0052] Further as shown in Figures 4, 5 and 7, a partition 341 is provided inside the contact member 34. The partition 341 is fixedly connected to the inner wall of the contact member 34. The partition 341 divides the contact member 34 from top to bottom into an air outlet chamber 342 and an air inlet chamber 343.

[0053] It should be noted that a partition 341 is added inside the contact 34. When the contact 34 moves along the edge of the magnet to the partition 341 and reaches the damaged position, the gas in the connecting pipe 33 passes through the outlet chamber 342 and then through the gap between the partition 341 and the damaged position of the magnet into the inlet chamber 343, or part of it enters the inlet chamber 343 and flows out directly from the broken position of the magnet.

[0054] The trachea 344 has a lower end that passes through a contact member 34 and is connected to an air inlet chamber 343, an upper end that passes through an L-shaped tube 35, and an airbag 345 connected to the top end of the trachea 344.

[0055] It is worth noting that the gas enters the airbag 345 through the air pipe 344 connected to the air inlet chamber 343. The airbag 345 expands as air is introduced. Since the airbag 345 is located inside the L-shaped tube 35, when the airbag 345 expands, the cross-section of the air inlet of the L-shaped tube 35 decreases, thereby reducing the air intake of the L-shaped tube 35. At this time, the thrust generated on the hollow ball 36 will decrease rapidly, causing the hollow ball 36 to fall rapidly and contact the triggering mechanism 37. This can shorten the time to activate the triggering mechanism 37 when the damaged area of ​​the magnet is detected.

[0056] As further shown in Figure 7, rubber strips 346 are attached to the edge of the opening end of the contact member 34 and the edge of the partition 341.

[0057] Rubber strips 346 are attached to the edge of the open end of the contact 34 and the edge of the partition 341 to increase the sealing between the contact 34 and the partition 341 and the edge of the magnet, making the detection more accurate.

[0058] As further shown in Figure 7, the triggering mechanism 37 includes:

[0059] Connecting ear 371, the connecting ear 371 is fixedly connected to the inner wall of the straight section of L-shaped tube 35, two sets of connecting ears 371 are symmetrically arranged, the top of the connecting ear 371 is arc-shaped, the upper surface of the connecting ear 371 is provided with electrode plate 372, and the hollow ball 36 is made of conductive metal.

[0060] When the hollow ball 36 falls, the connecting ear 371 can prevent the hollow ball 36 from falling further. When the thrust generated by the gas is insufficient to push the hollow ball 36 upward due to damage, the hollow ball 36, which is made of conductive metal, contacts the electrode plate 372 on the connecting ear 371 on both sides, and the circuit is connected. It can be determined that the magnet in the magnet slot is damaged.

[0061] As further shown in Figure 7, a barrier mesh 351 is provided at the open end of the top of the L-shaped tube 35;

[0062] A barrier net 351 is fixedly connected to the top of the L-shaped tube 35 so that when calibrating whether the hollow ball 36 has reached a state of equilibrium inside the L-shaped tube 35, the barrier net 351 can prevent the hollow ball 36 from flying out of the L-shaped tube 35 while allowing air to pass through.

[0063] As shown in Figures 2, 9, and 10, the ejection mechanism 40 includes:

[0064] A rotating disk 41 is provided with an electric cylinder 42. The outer shell of the electric cylinder 42 is fixedly connected to the rotating disk 41. The end of the internal telescopic rod of the electric cylinder 42 is fixedly connected to a push plate 43. The push plate 43 is used to cooperate with the electric cylinder 42 to push the magnet out of the rotor magnet slot.

[0065] It should be noted that after the testing mechanism 30 has completed the testing, the rotating disk 41 drives the electric cylinder 42 to rotate directly above the magnet slot with the damaged magnet. The electric cylinder 42 drives the push plate 43 to push the damaged magnet out of the magnet slot. Then, the moving base 20 drives the rotor fixing seat 21 to the pressing table to re-press the magnet.

[0066] Further, as shown in Figure 9, an arc-shaped disk 51 is provided on one side of the detection mechanism 30. The arc-shaped disk 51 is fixedly connected to the end of the internal telescopic rod of the second electric cylinder 52. The second electric cylinder 52 is provided on the top of the arc-shaped disk 51. A fixing frame 53 is fixedly connected to the outer shell of the second electric cylinder 52 for fixing the second electric cylinder 52. The fixing frame 53 is fixedly connected to the surface of the workbench. The bottom of the arc-shaped disk 51 is fixedly connected to the outer shell of the air pump 31. The air pump 31 is provided with several sets.

[0067] The arc-shaped disk 51 is driven by the electric cylinder 52 to move up and down along the rotor magnet slot, which can drive the contact 34 to slowly detect along the edge of the magnet. At least three sets of air pumps 31 are provided. By setting multiple sets of air pumps 31, the edge detection of magnets in multiple magnet slots can be achieved at the same time, which can improve the detection efficiency to a certain extent.

[0068] As further shown in Figure 9, the rotating disk 41 is rotatably connected to the internal telescopic rod of the electric cylinder 52. The inner wall of the rotating disk 41 is provided with a circumferential array of teeth 61. The surface of the arc-shaped disk 51 is provided with a servo motor 62. The outer shell of the servo motor 62 is fixedly connected to the arc-shaped disk 51. The end of the internal rotating shaft of the servo motor 62 is fixedly connected with a gear 63. The gear 63 meshes with the teeth 61 on the inner wall of the rotating disk 41.

[0069] After the testing mechanism 30 has finished testing the magnet slots on one side of the rotor, it will test the magnet slots on the other side. At this time, the servo motor 62 will drive the rotating disk 41 to rotate through the top gear 63 until the electric cylinder 42 on the rotating disk 41 moves to the magnet slot with the damaged magnet. The electric cylinder 42 will cooperate with the push plate 43 to push the damaged magnet out of the magnet slot until there is no damaged magnet in the tested magnet slot.

[0070] As further shown in Figure 10, the rotor fixing seat 21 has through slots 71 arranged in a circular array. The number of through slots 71 is equal to the number of rotor magnet slots. When the electric cylinder 42 drives the push plate 43 to push the damaged magnet, the damaged magnet will be discharged out of the magnet slot through the through slots 71 on the rotor fixing seat 21.

[0071] Further, as shown in Figure 10, it is worth noting that the top of the movable base 20 is fixedly connected to a placement tray 81 for placing magnets. A sliding plate 82 is slidably connected to one side of the placement tray 81. The discharged broken magnets fall into the placement tray 81. When the placement tray 81 is full, the sliding plate 82 can be pulled out to recover the broken magnets.

[0072] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0073] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, all of which fall within the scope of protection of the present invention.
