Description

[0003] Among them, in the field of motors, the rotor and stator are indispensable components of the motor. Most large-scale production enterprises use expensive large-scale production equipment for stator assembly, which is complex in structure and large in size and not suitable for small-scale production enterprises. At present, most small-scale production enterprises use manual assembly methods, with low assembly efficiency, low positioning accuracy, poor assembly effects, and a high product rejection rate, thus increasing production costs. Moreover, after the stator is assembled, the magnetic tiles inside the stator need to be magnetized to provide a stable magnetic field for the rotation of the motor to ensure the continuous rotation of the rotor. In the prior art, the magnetization method of the stator is to manually put the stator into the magnetizer for magnetization, and then manually take out the stator from the magnetizer after magnetization, which is not only time-consuming and laborious, but also has low processing efficiency.

[0038] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0039] As Figures 1 - 20As shown in the figure, the present invention provides a motor assembly device, which is characterized by comprising: a magnetic core feeding mechanism 10, a glue applying mechanism 20, a magnetic core positioning mechanism 30, a glue fixing mechanism 40, a stator placing mechanism 50, a housing feeding mechanism 60, a conveying mechanism 70, a conveying channel 80, a magnetic tile magnetizing device 110, and a magnetic flux measuring device 120; the magnetic core feeding mechanism 10 is used for placing magnetic cores and conveying the magnetic cores to the glue applying mechanism 20, the glue applying mechanism 20 is arranged at the end of the conveying direction of the magnetic core feeding mechanism 10 and is used for applying glue to the back surface of the magnetic core, the magnetic core positioning mechanism 30 corresponds to the glue applying mechanism 20 and is used for fixing the glued magnetic core on the magnetic core positioning mechanism 30 in a predetermined positional relationship, the glue fixing mechanism 40 is arranged on one side of the magnetic core positioning mechanism 30 and is used for accelerating the solidification of the glue; the stator placing mechanism 50 is used for placing the stator with the glue solidified and outputting the stator; the housing feeding mechanism 60 is arranged on the side of the magnetic core positioning mechanism 30 away from the glue fixing mechanism 40 and is used for conveying the stator housing; the conveying mechanism 70 is used for conveying the stator housing from the housing feeding mechanism 60 to the magnetic core positioning mechanism 30 and the glue fixing mechanism 40, and finally conveying it into the stator placing mechanism 50, the conveying channel 80 is arranged at an interval from the stator placing mechanism 50, and a conveying gripper (not shown in the figure) is further arranged between the conveying channel 80 and the stator placing mechanism 50, and this conveying gripper conveys the stator in the stator placing mechanism 50 onto the conveying channel 80, the magnetic tile magnetizing device 110 and the magnetic flux measuring device 120 are sequentially arranged on one side of the conveying channel 80, the magnetic tile magnetizing device 110 is used for magnetizing the magnetic tiles in the stator, the magnetic flux measuring device 120 is used for measuring the magnetic flux of the magnetized magnetic tiles, and after the magnetic flux measurement is completed, the assembly and testing of the stator are completed; a push block 81 is slidably arranged on the side of the conveying channel 80 away from the magnetic tile magnetizing device 110, a plurality of push arms 82 are arranged at intervals on the push block 81, and a groove 83 matching the stator housing is arranged on the push arm 82, the push block 81 can slide in the direction where the magnetic tile magnetizing device 110 is located and slide along the conveying direction of the conveying channel 80, when the conveying mechanism 70 conveys the stator in the stator placing mechanism 50 to a preset position on the conveying channel 80, the push block 81 drives the push arms 82 to move towards the conveying channel 80, so that the groove 83 on the push arms 82 catches the stator, and then moves along with the push block 81 in the conveying direction to realize the conveying of the stator.

[0040] It should be noted that a plurality of through holes 84 are arranged at intervals on the conveying channel 80, and each through hole 84 corresponds to a device arranged on the conveying channel 80.

[0041] Further, in this embodiment, the magnetic core feeding mechanism 10 includes: a placement plate 11, a first ejector rod 12, a conveyor belt 13, and a second ejector rod 14; there are two placement plates 11, and each placement plate 11 is provided with four placement grooves 112 for placing magnetic cores. The bottom of each placement plate 11 is respectively provided with a rectangular hole 111 that penetrates the placement plate 11, and the rectangular hole 111 communicates with the placement groove 112, so that the magnetic cores in the placement groove 112 can fall into the rectangular hole 111. The height of the rectangular hole 111 should be equal to the highest height of the magnetic core. A number of first ejector rods 12 are arranged side by side and are slidably arranged on one side facing the rectangular hole 111 driven by a cylinder or a motor. The first ejector rod 12 can be inserted into the rectangular hole 111 to push the magnetic core out of the rectangular hole 111. The conveyor belt 13 is arranged on the other side facing the rectangular hole 111. The conveyor belt 13 corresponds to the rectangular hole 111 and the first ejector rod 12, so that the magnetic core pushed out by the first ejector rod 12 directly enters the conveyor belt 13. A number of fixing positions for preventing the magnetic core from shifting during transportation are provided on the conveyor belt 13. When the magnetic core enters the fixing position, it is restricted by the fixing position to prevent it from moving. The second ejector rod 14 is slidably arranged on the end of the conveyor belt 13 away from the placement plate 11. The second ejector rod 14 corresponds to the glue applying mechanism 20. The magnetic core pushed out by the first ejector rod 12 enters the conveyor belt 13 and is conveyed to the other end by the conveyor belt 13. At this time, the second ejector rod 14 is used to push the magnetic core located here out of the conveyor belt 13 and push it into the glue applying mechanism 20.

[0042] Further, in this embodiment, the glue applying mechanism 20 includes: a glue dispensing device 21, a conveying trough 22, a dispensing slider 23, and a core ejecting block 24; the conveying trough 22 conveys the cores, and the width of the conveying trough 22 is equal to the width of the cores, enabling it to convey the cores in a single row only. The glue dispensing device 21 is arranged above the conveying trough 22 and is used for applying glue to the cores in the conveying trough 22. The dispensing slider 23 is slidably arranged at one end of the conveying trough 22 away from the core feeding mechanism 10. Two matching grooves 231 are arranged at intervals on the dispensing slider 23, and the matching grooves 231 match the cores. During operation, one of the matching grooves 231 corresponds to the conveying trough 22, and the core at the end is pushed by the second ejector rod 14 to push the core at the head into the matching groove 231. At this time, the dispensing slider 23 moves horizontally to make the other matching groove 231 correspond to the conveying trough 22, and another core is pushed into the matching groove 231 to wait for the subsequent process. There are two core ejecting blocks 24, and the two core ejecting blocks 24 are respectively slidably arranged on one side of the dispensing slider 23. The two core ejecting blocks 24 are respectively located at both ends of the dispensing slider 23, and the center of the two core ejecting blocks 24 is the position where the conveying trough 22 is located. The distance between the two matching grooves is the distance from one of the core ejecting blocks 24 to the conveying trough 22. When one matching groove 231 corresponds to the conveying trough 22, the other matching groove 231 corresponds to one of the core ejecting blocks 24. When the core ejecting block 24 moves, the core in the corresponding matching groove 231 is ejected; the same applies to the other matching groove 231, so as to achieve uninterrupted operation and improve work efficiency. The core ejecting block 24 matches the matching groove 231.

[0043] Further, in this embodiment, the magnetic core positioning mechanism 30 includes: a positioning shaft 31, a rotating shaft 32, and a base 33; two positioning grooves 311 for fixing the magnetic core are provided at the top of the positioning shaft 31. The shape and size of the positioning groove 311 match those of the magnetic core. When the magnetic core enters the positioning groove 311, the magnetic core can only be pushed out from the entering direction and cannot be taken out from other directions; the positioning shaft 31 corresponds to the glue applying mechanism 20, and the position of the positioning shaft 31 corresponds to that of the magnetic core top block 24. A magnetic core push block 312 for pushing out the magnetic core is further provided at the bottom of the positioning shaft 31. When it is necessary to push out the magnetic core on the positioning shaft 31, the positioning shaft 31 expands and contracts, and the magnetic core push block 312 pushes the magnetic core out of the positioning groove 311. The end of the positioning shaft 31 is connected to a driving motor for driving the positioning shaft 31 to rotate. Since the positions of the two positioning grooves 311 are in two opposite directions, in order to enable both positioning grooves 311 to place the magnetic core, it is necessary to install a driving motor to drive the positioning shaft 31 to rotate, so as to install the magnetic cores in the positioning grooves 311 respectively; for the convenience of installing and removing the magnetic core in the positioning groove 311, the driving motor is rotatably connected to the base 33, and a rotating shaft 32 is rotatably connected to one side of the driving motor. The rotating shaft 32 is driven by a cylinder. When the cylinder expands and contracts, the driving motor rotates. The rotating shaft 32 is arranged on the side of the driving motor facing the glue applying mechanism 20. When the cylinder contracts the rotating shaft 32, the driving motor rotates under the pulling of the rotating shaft 32, so that the positioning shaft 31 corresponds to one of the matching grooves 231, and thus the magnetic core on the matching groove 231 can enter the positioning groove 311. When the installation is completed, the cylinder expands and contracts the rotating shaft 32, pushing the driving motor to rotate in the reverse direction, so that the positioning shaft 31 is in an upward state, waiting for subsequent processes. The magnetic core positioning mechanism 30 further includes: a fitting mounting seat 34 provided on one side of the base 33. Two pulling blocks 35 are oppositely provided on the fitting mounting seat 34. The two pulling blocks 35 can move towards each other or move away from each other. The pulling blocks 35 are vertically and slidably arranged on the fitting mounting seat 34. A placing step 36 for placing the outer shell is provided at the bottom of the pulling block 35. The first conveying component 72, after clamping the outer shell and transferring the magnetic core, moves above the fitting mounting seat 34 and corresponds to the pulling blocks 35. At this time, the magnetic core conveying shaft 722 first transfers the magnetic core to the two pulling blocks 35 and sleeves the outer shell on the two pulling blocks 35. Then the pulling blocks 35 move away from each other, driving the magnetic core on the pulling blocks 35 to fit with the inner wall of the outer shell. Under the action of glue, the magnetic core and the outer shell are preliminarily fixed together to form a stator. Then the first conveying component 72 moves back to its original position, and the second conveying component 73 moves above the fitting mounting seat 34, clamps the stator and moves it to the glue fixing mechanism 40.

[0044] It should be noted that there are two magnetic core positioning mechanisms 30, and the distance between the two is equal to the distance between the two magnetic core top blocks 24. When one matching groove 231 is installing a magnetic core, the other matching groove 231 is in the state of installing the magnetic core into the corresponding magnetic core positioning mechanism 30. In this way, reciprocatingly, uninterrupted installation between the two magnetic core positioning mechanisms 30 is achieved.

[0045] Furthermore, the outer shell feeding mechanism 60 includes: an outer shell conveying track 61, outer shell clamping arms 62, and an outer shell placement position 63; the outer shell clamping arms 62 are arranged at one end of the outer shell conveying track 61, and the outer shell placement position 63 is located at the end of the outer shell conveying track 61 where the outer shell clamping arms 62 are provided.

[0046] Furthermore, the conveying mechanism 70 includes: a gantry 71, a first conveying component 72, and a second conveying component 73; the gantry 71 corresponds to the outer shell feeding mechanism 60, the magnetic core positioning mechanism 30, and the glue fixing mechanism 40. The first conveying component 72 and the second conveying component 73 are slidably arranged on the gantry 71. The first conveying component 72 includes an outer shell clamping jaw 721 and a magnetic core conveying shaft 722. Among them, the magnetic conveying shaft has the same function as the magnetic core positioning mechanism 30; the outer shell clamping jaw 721 is used to clamp the outer shell, and the magnetic core conveying shaft 722 is used to convey the magnetic core of the magnetic core positioning mechanism 30; the second conveying component 73 includes two stator clamping jaws 731. The two stator clamping jaws 731 are used to clamp the stator located on the glue fixing mechanism 40 and convey it to the stator placement mechanism 50. During operation, the outer shell clamping jaw 721 clamps the outer shell on the outer shell placement position 63 and moves to a position corresponding to the magnetic core conveying shaft 722 and the positioning shaft 31. At this time, the magnetic core on the positioning shaft 31 is transferred to the magnetic core conveying shaft 722. At this time, the first conveying component 72 moves to the next process.

[0047] Furthermore, in this embodiment, the glue fixing mechanism 40 includes: a curing seat 41 and a heating tube 42; there are several curing seats 41 arranged side by side. The bottom of the curing seat 41 is connected to a motor, and the curing seat 41 is driven by the motor to rotate itself. The top of the curing seat 41 is provided with a preset position 411 for placing the outer shell. The second conveying component 73 transports the stator here and places the stator on the preset position 411. The heating tube 42 is arranged in a rectangle around the top of the curing seat 41 corresponding to the preset position 411. The heating tube 42 is spaced from the curing seat 41. When the heating tube 42 works, it emits heat and transfers it to the stator to accelerate the solidification of the glue. At the same time, the curing seat 41 will continue to rotate, so as to make the heating of the curing seat 41 more uniform.

[0048] Further, in this embodiment, the stator placement mechanism 50 includes: a placement area 51, a winding push block 52, a first cylinder push block 53, a second cylinder push block 54, a third cylinder push block 55, and placement members 56; there are several placement members 56, and the placement members 56 are evenly arranged along the placement area 51. The winding push block 52 is arranged at one end of the placement area 51 and can push the placement members 56 along this side. The first cylinder push block 53 is arranged at the other end of the side of the placement area 51 where the winding push block 52 is located and can push the placement members 56 along the adjacent side. The second cylinder push block 54 is arranged at the other end of the side of the placement area 51 where the first cylinder push block 53 is located and can push the placement members 56 along the adjacent side. The third cylinder push block 55 is arranged in the middle of the side opposite to the winding push block 52 and can push the placement members 56 in the direction of the winding push block 52. When the stator in the curing mechanism has been cured, the second conveying component 73 clamps and conveys the stator to the stator placement mechanism 50, corresponding to the placement member 56 on one side of the third cylinder push block 55, and places the stator on the placement member 56. At this time, the second cylinder push block 54 moves the placement member 56 along the side where the third cylinder push block 55 is located. At this time, because the second cylinder push block 54 has pushed one placement member 56, a vacant position will appear in the original position of the placement member 56. At this time, the first cylinder push block 53 works to push one placement member 56 to fill the vacant position. Similarly, at this time, the winding push block 52 works to push one placement member 56 to fill the position until all the placement members 56 on the side where the winding push block 52 is located are completely pushed. The winding push block 52 returns to its original position, and the third cylinder push block 55 pushes the placement members 56 on its side in the direction of the winding push block 52 to push the placement members 56, so that the placement members 56 fill the vacant positions on the side where the winding push block 52 is located, and so on.

[0049] It should be noted that the winding push block 52 will only return to its initial position when all the placement members 56 on the side where it is located have been pushed. The third cylinder push block 55 will only work to push the entire row of placement members 56 in the direction of the winding push block 52 when the number of placement members 56 on its side reaches a certain amount; the first cylinder push block 53 and the second cylinder push block 54 both perform reciprocating motions, that is, they will return to their original positions after pushing one placement member 56 and wait to push the next placement member 56.

When in use, the cylinder drives the measuring device 1002 to rise, so that the two measuring devices 1002 rise and the tops of the two measuring devices 1002 abut against the magnetic tiles in the stator, and the installation height of the magnetic tile on the stator housing is calculated through the compression amount of the measuring device 1002. Since the calculation method of the measuring device 1002 is based on the fact that the rising amount of the measuring device 1002 and the position of the stator are fixed, the height of the magnetic tile on the stator housing can be obtained through the compression amount of the measuring device 1002.
