Description

Technical Field

[0001] The present invention relates to the technical field of motors, and specifically to a motor assembly device and method. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses a stator winding to generate a rotating magnetic field that acts on the rotor to form a magneto-electric driving rotational torque. Motors are classified into DC motors and AC motors according to the power supply used. With the development of industry, many types of motors have emerged, such as asynchronous motors, servo motors, permanent magnet motors, etc. Among them, a permanent magnet motor is a special type of motor whose magnetic field system consists of one or more permanent magnets. For the installation of some special permanent magnet motors, the permanent magnets need to be installed inside the housing and fixed. The most common way to fix the permanent magnet to the motor housing is by using special glue.

[0003] The existing patent publication number is: CN114679020B, which discloses a motor permanent magnet assembly device. This assembly device applies glue to the side walls of multiple permanent magnets through a glue dispensing device, so that the multiple permanent magnets are fixedly connected. Subsequently, the permanent magnets are placed inside the motor housing to complete the assembly. During the production process of the permanent magnets, a large amount of oil stain will adhere to the permanent magnets. Moreover, when the staff installs the permanent magnets on the extension part, the glue-coated surface of the permanent magnets will also adhere to a large amount of oil stain. When the oil-stained permanent magnets are fixed with glue, they are prone to fall off and separate during use, which may cause danger during use.

[0004] Based on this, a motor assembly device and method are now provided to eliminate the drawbacks of the existing device. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1.

[0019] 2. By providing a brush plate, a spraying pipe, a water absorption roller and an exhaust pipe inside the cleaning box, and driving the mounting rotating shaft to rotate by a second motor, the present invention facilitates the cleaning of the oil stains on the surfaces of multiple permanent magnet bodies and enables the rapid drying of the permanent magnet bodies, solving the problem of inconvenient cleaning of the oil stains on the surface of the permanent magnet.

At the same time, by providing a top rod and a stop plate, the mounting rotating shaft can be fixed when switching the position of the mounting support rod, preventing the position deviation of the permanent magnet body during the switching process. By providing a limiting circular plate and a push rod, it is convenient to drive the push rod to move when installing, so that the push rod pushes the permanent magnet body out of the inside of the loading rack, making the permanent magnet body closely attached to the installation position inside the motor housing. At the same time, under the action of the first guiding block, the loading rack moves away from the permanent magnet body, facilitating the removal of the loading rack, thereby increasing the practicality of the motor assembly device. And by directly fixedly connecting the permanent magnet body to the inside of the motor housing, the fixing effect on the permanent magnet body is increased. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] In one embodiment, as Figures 1 - 12As shown in the figure, a motor assembly device includes mounting support rods 11, a cleaning tank 52, a dispensing component 65, and a fixing mold 66. The cleaning tank 52, the dispensing component 65, and the fixing mold 66 are all fixedly arranged at the upper end of the workbench 16. The two mounting support rods 11 are symmetrically arranged on the first internal spline shaft 12. A switching component for switching the positions of the mounting support rods 11 is provided on the first internal spline shaft 12. Mounting rotating shafts 18 are rotatably arranged in the mounting holes at the upper ends of the mounting support rods 11. A number of first fixing rods 19 are circularly arranged at one end of the mounting rotating shaft 18. Sliding tubes 20 are slidably arranged on the first fixing rods 19. Loading frames 21 for loading permanent magnet bodies 22 are fixedly arranged at one ends of the sliding tubes 20. A cleaning mechanism for cleaning the surfaces of the permanent magnet bodies 22 is arranged inside the cleaning tank 52. Stopping mechanisms for fixing the mounting rotating shafts 18 are arranged at the bottom ends of the mounting support rods 11. A pushing mechanism for facilitating the installation of the permanent magnet bodies 22 is arranged on the mounting rotating shafts 18. The cleaning mechanism facilitates the cleaning of the gluing surfaces of the permanent magnet bodies 22. The stopping mechanisms fix the mounting rotating shafts 18 when the mounting support rods 11 are switched. The pushing mechanism facilitates the pushing out of the permanent magnet bodies 22 inside the loading frames 21 for installation during installation;

[0035] The switching component includes a first electric push rod 14. The output end of the first electric push rod 14 is rotatably connected to one end of the first internal spline shaft 12. The first electric push rod 14 is fixedly arranged in the mounting hole at the upper end of the top plate 17. A number of support columns are fixedly arranged at the bottom end of the top plate 17. A number of the support columns are all fixedly arranged at the upper end of the workbench 16. A first external spline shaft is slidably arranged inside the first internal spline shaft 12. The first external spline shaft is fixedly arranged at one end of the first fixed shaft 13. A fixed tube is rotatably arranged on the first fixed shaft 13. The fixed tube is fixedly arranged in the mounting hole at the upper end of the workbench 16. One end of the first fixed shaft 13 is fixedly connected to the output end of the first motor 15. The first motor 15 is fixedly arranged at the bottom end inside the workbench 16. During use, when it is necessary to switch the positions of the two mounting support rods 11, the output end of the first electric push rod 14 drives the first internal spline shaft 12 to move. The first internal spline shaft 12 drives a number of loading frames 21 to move through the two mounting support rods 11, so that the bottom ends of the loading frames 21 are far away from the cleaning tank 52, the dispensing component 65, and the fixing mold 66. Then, the first motor 15 is started. The output end of the first motor 15 drives the first fixed shaft 13 to rotate. Since the first internal spline shaft 12 and the first external spline shaft are connected by splines, and the first external spline shaft is fixedly arranged at one end of the first fixed shaft 13, the first fixed shaft 13 drives a number of loading frames 21 to rotate through the first internal spline shaft 12. It should be noted that in this application, the first motor 15 rotates 90 degrees each time and then stops, and the following will not be elaborated anymore.

[0036] The cleaning mechanism includes a first sliding frame 53 and a second sliding frame 55. Both the first sliding frame 53 and the second sliding frame 55 are arranged inside the cleaning tank 52. The first sliding frame 53 and the second sliding frame 55 are fixedly connected by a plurality of second fixing rods. An exhaust pipe 54 is fixedly arranged inside the first sliding frame 53. A plurality of air outlet holes are arranged on one side of the exhaust pipe 54. The input end of the exhaust pipe 54 is communicated with the output end of an external air supply component. Inside the second sliding frame 55, a brush plate 56, a spraying pipe 57 and a water absorption roller 58 are arranged in sequence. A plurality of bristles are arranged on one side of the brush plate 56. A plurality of spraying holes are arranged on one side of the spraying pipe 57. The input end of the spraying pipe 57 is communicated with the output end of an external water supply component. A water absorption layer is arranged on the surface of the water absorption roller 58. The rotating shafts at both ends of the water absorption roller 58 are rotatably arranged inside the second sliding frame 55. One side of the second sliding frame 55 is fixedly provided with an extension plate. The extension plate is slidably arranged in a rectangular through hole on one side of the cleaning tank 52. The upper end of the extension plate is fixedly connected with the output end of a third electric push rod 59. The third electric push rod 59 is fixedly arranged on one side of the cleaning tank 52. The bottom end of the cleaning tank 52 is communicated with the input end of a drain pipe 60. The drain pipe 60 is arranged inside the workbench 16. One end of the installation rotating shaft 18 is provided with a rotating component for driving the loading rack 21 to rotate. When in use, such as Figure 9 and Figure 10As shown, when assembling the permanent magnet body 22, the staff stands on the side opposite to the dispensing component 65. When a mounting support rod 11 rotates to the side where the staff is located, the output end of the first electric push rod 14 drives the mounting support rod 11 to descend through the first inner spline shaft 12. The staff places several permanent magnet bodies 22 inside several loading racks 21 respectively. The permanent magnet bodies 22 adsorb the loading racks 21 to fix the permanent magnet bodies 22. Then the output end of the first electric push rod 14 drives the mounting support rod 11 to rise. The first motor 15 drives the installed loading rack 21 to rotate above the cleaning box 52. The first electric push rod 14 drives the mounting support rod 11 to descend, so that the permanent magnet body 22 moves into the cleaning box 52. At this time, the output end of the third electric push rod 59 drives the second sliding rack 55 and the first sliding rack 53 to move, so that the bristles on one side of the brush plate 56 and the water absorption roller 58 are in close contact with the permanent magnet body 22. Then the external water supply component provides cleaning liquid to the inside of the spray pipe 57, and the spray pipe 57 sprays the cleaning liquid through several spray holes. The cleaning liquid is evenly sprayed on the glue-coated surface of the permanent magnet body 22, and the mounting shaft 18 is driven to rotate through the rotating assembly. The mounting shaft 18 drives the permanent magnet body 22 to rotate through a plurality of loading racks 21, so that the spray pipe 57 cleans a plurality of permanent magnet bodies 22. At the same time, since the bristles on one side of the brush plate 56 are in close contact with the permanent magnet body 22, the surface of the permanent magnet body 22 is cleaned. Then, the water-absorbing layer on the surface of the water-absorbing roller 58 absorbs the cleaning liquid on the surface of the permanent magnet body 22, and the used cleaning liquid is discharged through the drain pipe 60. After the cleaning is completed, the output end of the third electric push rod 59 pushes the second sliding frame 55 to move, so that the water absorption roller 58 is away from the permanent magnet body 22, and the exhaust pipe 54 is close to the permanent magnet body 22. The external air supply component provides gas to the exhaust pipe 54, and the exhaust pipe 54 discharges the gas through a plurality of air outlets, so as to accelerate the drying of the permanent magnet body 22. After the drying is completed, the output end of the first electric push rod 14 separates the permanent magnet body 22 from the inside of the cleaning box 52 through the first inner spline shaft 12 and the mounting support rod 11.

[0037] The rotating assembly includes two second motors 42, which are respectively arranged above the cleaning tank 52 and the brush plate 56. The second motors 42 are fixedly arranged on the second mounting brackets 45, and both of the second mounting brackets 45 are fixedly arranged at the bottom end of the top plate 17. Second friction wheels are fixedly arranged on the output ends of the second motors 42, and first friction wheels 41 are frictionally arranged on the second friction wheels. The first friction wheels 41 are fixedly arranged on the second fixed shaft. A plurality of rotating plates are rotatably arranged on the second fixed shaft. The rotating plates are fixedly arranged at the upper end of the connecting mounting plate 38. A second internal spline shaft 37 is fixedly arranged on the connecting mounting plate 38. A second external spline shaft 36 is slidably arranged on the second internal spline shaft 37. One ends of two second external spline shafts 36 are respectively fixedly arranged at one ends of two mounting rotating shafts 18. Sixth return springs 39 are fixedly arranged between the bottom end of the connecting mounting plate 38 and the upper end of the mounting support rod 11. The other end of the second fixed shaft is fixedly provided with a second conical friction wheel, and a first conical friction wheel 40 is frictionally arranged on the second conical friction wheel. The first conical friction wheel 40 is fixedly arranged at one end of the second internal spline shaft 37. During use, when the permanent magnet body 22 is being cleaned, the output end of the first electric push rod 14 drives the permanent magnet body 22 to descend through the first internal spline shaft 12 and the mounting support rod 11. At the same time, the mounting rotating shaft 18 drives the second friction wheel to move. When the permanent magnet body 22 stops moving, the first friction wheel 41 is in close contact with the second friction wheel at the output end of the second motor 42 above the cleaning tank 52. Subsequently, the second motor 42 is started, so that the second fixed shaft drives the mounting rotating shaft 18 to rotate through the frictional cooperation between the second conical friction wheel and the first conical friction wheel 40. The mounting rotating shaft 18 drives a plurality of permanent magnet bodies 22 to rotate. After the cleaning is completed, the first motor 15 drives the first internal spline shaft 12 to rotate, so that the cleaned permanent magnet body 22 moves above the dispensing component 65. The output end of the first electric push rod 14 pushes the first internal spline shaft 12 to move, so that the cleaned mounting support rod 11 is aligned with the output end of the dispensing component 65. At the same time, the first friction wheel 41 is in close contact with the second friction wheel at the output end of the second motor 42 above the dispensing component 65. Subsequently, the output end of the dispensing component 65 dispenses glue on the surface of the permanent magnet body 22. At the same time, the output end of the second motor 42 drives the mounting rotating shaft 18 to rotate, so that the dispensing component 65 evenly dispenses glue on the surfaces of a plurality of permanent magnet bodies 22. It should be noted that the dispensing component 65 in this application adopts existing components, and the figure is a schematic diagram. Other models can be selected for actual use.

[0038] An extrusion roller is closely arranged on the water absorption roller 58. The rotating shafts at both ends of the extrusion roller are rotatably arranged inside the second sliding frame 55. During use, when the water absorption roller 58 adsorbs the cleaning liquid on the permanent magnet body 22, since the water absorption roller 58 is closely attached to the surface of the permanent magnet body 22, the rotation of the permanent magnet body 22 will drive the water absorption roller 58 to rotate. Since the extrusion roller is closely attached to the water absorption roller 58 and extrudes the water absorption roller 58, when the water absorption roller 58 rotates, the extrusion roller can extrude the cleaning liquid adsorbed inside the water absorption roller 58, enabling the water absorption roller 58 to continuously adsorb the cleaning liquid on the surface of the permanent magnet body 22.

[0039] The stopping mechanism includes a stopping plate 51 which is arc-shaped. A stopping ring is closely arranged inside the stopping plate 51. The two stopping rings are respectively fixed on the two mounting rotating shafts 18. The stopping plate 51 is fixed at one end of the sliding plate 49. A number of fixed support plates are slidably arranged on the sliding plate 49, and the fixed support plates are all fixed at the bottom ends of the mounting support rods 11. The other end of the sliding plate 49 is fixed with a first fixing plate. One side of the first fixing plate is fixedly connected to one end of a fourth return spring 50. The other end of the fourth return spring 50 is fixedly provided with a second fixing plate which is fixed at the bottom end of the mounting support rod 11. A second guiding block 48 is fixed in the mounting groove at the upper end of the sliding plate 49. One end of a connecting rod 47 is closely attached to the inclined surface of the second guiding block 48. The connecting rod 47 is L-shaped. The other end of the connecting rod 47 is fixed at the bottom end of the connecting mounting plate 38. A push rod 43 is fixed on one side at the bottom end of the connecting mounting plate 38. One end of the push rod 43 is closely attached to a support block 46. A number of the support blocks 46 are respectively fixed at one end of a first mounting frame 44 and two second mounting frames 45. The first mounting frame 44 is fixed at the bottom end of the top plate 17. The first mounting frame 44 and the second mounting frame 45 above the dispensing component 65 are symmetrically arranged. During use, when the staff installs the permanent magnet body 22 into the loading rack 21, the cleaning tank 52 cleans the permanent magnet body 22, and the dispensing component 65 dispenses glue on the permanent magnet body 22, the output end of the first electric push rod 14 drives the mounting rotating shaft 18 to move through the first internal spline shaft 12. When one end of the push rod 43 is closely attached to the upper end of the support block 46 and the output end of the first electric push rod 14 continues to move, the second internal spline shaft 37 slides on the second external spline shaft 36.

At the same time, the other installation support rod 11 rotates to the loading position. The staff loads the loading rack 21 on the other installation shaft 18 while dispensing glue. Then the first electric push rod 14 drives the permanent magnet body 22 to rise, and the stop plate 51 fixes the installation shaft 18. The first motor 15 drives the first internal spline shaft 12 to rotate to switch the position of the installation support rod 11.
