Description

Technical Field

[0001] This utility model relates to the field of rotor manufacturing technology, and in particular to a rotor magnetic sheet assembly equipment. Background Technology

[0002] In the rotor manufacturing process, magnetic sheet loading is a critical step that plays a decisive role in the rotor's performance. Traditionally, magnetic sheet assembly is mainly done manually. Operators must manually and precisely place each magnetic sheet into the rotor's loading slot.

[0003] However, the magnetic sheets themselves are small in size, and each rotor needs to be filled with multiple magnetic sheets, which makes the entire assembly process not only cumbersome and complicated, but also extremely time-consuming and labor-intensive, resulting in reduced production efficiency.

[0004] Furthermore, manual labor involving repetitive magnetic sheet loading over extended periods is highly susceptible to errors such as omissions or overloading due to fatigue and distraction. These seemingly minor mistakes can severely impact the quality of subsequent rotors, jeopardizing the product's stability and reliability. Utility Model Content

The pushing block is arranged on the output end of the second pushing cylinder. The second pushing cylinder is used to drive the pushing block to push multiple magnetic pieces in the stop groove, so that the magnetic piece located at the foremost end in the pushing direction of the pushing block abuts against the limiting groove.

[0016] The output end of the third pushing cylinder is set vertically upward, the connecting plate is set at the output end of the third pushing cylinder, and the push rod is set longitudinally on the connecting plate.

[0049] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0050] This embodiment provides a rotor magnetic sheet assembly device, such as... Figures 1 to 13 As shown, it includes a workbench 6 and a feeding mechanism 1, a transferring mechanism 2, a pushing mechanism 3, a storage fixture 5, and a pressing mechanism 4 disposed on the workbench 6;

[0051] Multiple magnetic sheets 71 are arranged on the feeding mechanism 1. The pushing mechanism 3 is provided with a feeding channel 30 and a pushing channel 31. The feeding channel 30 and the pushing channel 31 are connected. The material transfer mechanism 2 is set between the feeding mechanism 1 and the pushing mechanism 3 and is used to transport multiple magnetic sheets 71 to the feeding channel 30.

[0052] The storage fixture 5 is set at a position corresponding to the pushing mechanism 3. The storage fixture 5 is provided with multiple storage channels 50, which correspond to the pushing channels 31. The pushing mechanism 3 is used to push multiple magnetic sheets 71 in the feeding channel 30 into the multiple storage channels 50 of the storage fixture 5 through the pushing channels 31.

[0053] The pressing mechanism 4 is located at one end of the storage fixture 5. The pressing component 40 of the pressing mechanism 4 corresponds to one end of the storage channel 50. The rotor 7 is located at the other end of the storage fixture 5. The loading groove 70 of the rotor 7 corresponds to the other end of the storage channel 50. The pressing mechanism 4 drives the pressing component 40 to extend from one end of the storage channel 50 to press the magnetic sheet 71 in the storage channel 50 from the other end of the storage channel 50 into the loading groove 70 of the rotor 7.

[0054] The number of magnetic pieces 71 in this embodiment can be set according to the number to be filled in each rotor 7. For example, if each rotor 7 in this embodiment needs to be filled with 16 magnetic pieces 71, the 16 magnetic pieces 71 can be divided into a group. The material transfer mechanism 2 will simultaneously transport 16 magnetic pieces 71 to the feeding channel 30 each time to improve assembly efficiency. However, it is not limited to this. In other embodiments, it can also be set according to the actual situation.

[0055] The equipment implemented in this case integrates multiple automated mechanisms such as feeding, transferring, pushing, and pressing. Compared with the traditional manual assembly method, it avoids the inefficiency caused by factors such as human fatigue and inconsistent operating speed, improves assembly efficiency, and ensures the production quality of the subsequent rotor 7.

[0056] like Figure 1 As shown, the feeding mechanism 1 includes a feeding electric cylinder 10 and a tray 11. The feeding electric cylinder 10 is set on the workbench 6 and its output end is set vertically upward. The tray 11 is detachably set on the output end of the feeding electric cylinder 10. The tray 11 is provided with a plurality of feeding slots 12 for placing magnetic sheets 71.

[0057] In practical use, the magnetic sheets 71 can be pre-placed in the loading slot 12 of the tray 11. Therefore, when preparing materials, the operator only needs to place the tray 11 at the output end of the loading cylinder 10, which is simple to operate. In addition, as a further optimization, a push plate can be additionally set in the loading mechanism 1, so that multiple trays 11 can be stacked on the output end of the loading cylinder 10, reducing manual material preparation and further improving loading efficiency. When all the magnetic sheets 71 on the top tray 11 have been loaded, the push plate pushes the top tray 11 out of the loading mechanism 1, and then the loading cylinder 10 drives the next layer of trays 11 to move upward to continue loading. The structure is simple.

[0058] like Figure 1 and Figure 2 As shown, the material transfer mechanism 2 includes an industrial robot 20, a clamping cylinder 21, and grippers 22. The industrial robot 20 is mounted on the workbench 6, the clamping cylinder 21 is mounted on the industrial robot 20 with its output end pointing vertically downward, and the two grippers 22 are mounted on the output end of the clamping cylinder 21.

[0059] The industrial robot 20 in this embodiment can use existing devices. When the industrial robot 20 grips the magnetic sheet 71, it can accurately move the clamping cylinder 21 and the gripper 22 to the position of the magnetic sheet 71. The movement is flexible, ensuring the smooth progress of the feeding process and improving the feeding efficiency.

[0060] like Figures 3 to 5 As shown, the feeding mechanism 3 includes a feeding track 32, a first feeding cylinder 33, a stop block 34, a first servo motor 37, and a limiting baffle 38;

[0061] The feeding track 32 is horizontally set on the workbench 6 to form the feeding channel 30. One end of the feeding track 32 is provided with a first pushing cylinder 33, the output end of which corresponds to the feeding channel 30. The other end of the feeding track 32 is provided with a stop block 34, and the stop block 34 is provided with multiple baffles 35 around its circumference. A first servo motor 37 is connected to the stop block 34 and is used to drive the stop block 34 to rotate so that the multiple baffles 35 correspond to the other end of the feeding track 32 respectively. Two limiting baffles 38 are set at the other end of the feeding track 32 and abut against the baffles 35 to form a baffle groove 36 that communicates with the other end of the feeding track 32. The output end of the first pushing cylinder 33 is used to push the multiple magnetic pieces 71 of the feeding channel 30 into the baffle groove 36.

[0062] In this embodiment, the magnetic sheet 71 is elongated. When multiple magnetic sheets 71 are placed in a group on the feeding track 32, the length direction of the magnetic sheet 71 is consistent with the length direction of the feeding track 32, which facilitates the subsequent feeding process.

[0063] In this embodiment, the stop block 34 is a cuboid with equal length and width and a height less than its length and width. Specifically, the top and bottom surfaces of the stop block 34 are squares, and its four sides are rectangles. A first servo motor 37 is rotatably connected to either the top or bottom surface of the stop block 34, driving it to rotate. The side of the stop block 34 is level with the other end of the feeding track 32, and the height of the stop block 34 is the same as the width of the feeding track 32. Each side of the stop block 34 is provided with an L-shaped baffle 35, which has a short side and a long side. The short side of the baffle 35 is perpendicularly connected to the side of the stop block 34, making the long side of the baffle 35 parallel to the side of the stop block 34. Two limiting baffles 38 abut against the baffle 35, forming a groove 36 to facilitate the pusher cylinder 33's output end pushing multiple magnetic pieces 71 from the feeding channel 30 into the groove 36.

[0064] Since the stop block 34 is clamped by two limiting baffles 38, to facilitate the rotation of the stop block 34 by the first servo motor 37, both limiting baffles 38 are provided with clearance holes 315, while the stop block 34 is provided with a connecting hole 316. The shaft of the first servo motor 37 passes through the clearance hole 315 and is rotatably connected to the connecting hole 316, thereby driving the stop block 34 to rotate between the two rotating limiting baffles 38. Of course, in other embodiments, the stop block 34 and the baffle plate 35 can be integrally molded for easy production. By adjusting the dimensions of the feeding track 32, the stop block 34, and the baffle plate 35, different sizes of magnetic sheets 71 can be accommodated, making operation simple.

[0065] like Figures 3 to 5 As shown, the pushing mechanism 3 also includes a second pushing cylinder 310, a pushing block 311, a third pushing cylinder 312, a connecting plate 313, and a pushing rod 314;

[0066] One of the two limiting baffles 38 has a limiting groove 39 on the side near the stop block 34. The limiting groove 39 is arranged longitudinally to form the pushing channel 31. The output end of the second pushing cylinder 310 is arranged horizontally and is located on the other limiting baffle 38 of the two limiting baffles 38. Figure 3 To facilitate observation of the stop block 34, another limiting baffle 38 is not shown. The push block 311 is set at the output end of the second push cylinder 310. The second push cylinder 310 is used to drive the push block 311 to push the multiple magnetic pieces 71 in the stop groove 36, so that the magnetic piece 71 at the foremost end of the push block 311 push direction abuts against the limiting slide groove 39.

[0067] The output end of the third pushing cylinder 312 is set vertically upward, the connecting plate 313 is set at the output end of the third pushing cylinder 312, and the push rod 314 is set longitudinally on the connecting plate 313. The third pushing cylinder 312 is used to drive the push rod 314 to extend from the upper end of the limiting slide groove 39 through the connecting plate 313 and push the magnetic piece 71 in the limiting slide groove 39 out from the lower end of the limiting slide groove 39.

[0068] Specifically, since the stop block 34 in this embodiment is cuboid, during material feeding, the side of the stop block 34 is flush with the other end of the feeding track 32 at a horizontal height. After the output end of the first pushing cylinder 33 pushes the multiple magnetic pieces 71 of the feeding channel 30 into the stop groove 36, the first servo motor 37 drives the stop block 34 to rotate clockwise between the two limiting baffles 38, causing the multiple magnetic pieces 71 in the stop groove 36 to rotate to the position of the limiting slide groove 39. The second pushing cylinder 310 drives the pushing block 311 to... Multiple magnetic pieces 71 in the push block 311 are pushed into the limiting groove 39. The magnetic piece 71 at the forefront of the push block 311 abuts against the limiting groove 39, meaning that only one magnetic piece 71 is pushed into the limiting groove 39 at a time. Then, the third pushing cylinder 312 drives the push rod 314 through the connecting plate 313 to extend from the upper end of the limiting groove 39 and push the magnetic piece 71 in the limiting groove 39 out from the lower end of the limiting groove 39, so that the magnetic piece 71 falls into a storage channel 50 of the storage fixture 5 at the lower end of the limiting groove 39. Figure 8 As shown, this process is repeated until all the magnetic pieces 71 in the retaining groove 36 are pushed into the storage channel 50 of the storage fixture 5.

[0069] Therefore, in this embodiment, the feeding track 32 is horizontally arranged, the limiting groove 39 is vertically arranged, and the magnetic sheet 71 changes from horizontal to vertical as the stop block 34 rotates, facilitating the material pushing process. Specifically, while the first servo motor 37 drives the stop block 34 to rotate clockwise between the two limiting baffles 38, the other grooves 36 without magnetic sheets 71 will simultaneously rotate to a position level with the other end of the feeding track 32, facilitating the output of the first pushing cylinder 33 to continue pushing multiple magnetic sheets 71 from the feeding channel 30 into the grooves 36 without magnetic sheets 71, effectively improving the material pushing efficiency.

[0070] like Figure 1 As shown, this embodiment also includes a storage tray 60, which is disposed between the feeding mechanism 1 and the pushing mechanism 3. The storage tray 60 is provided with a plurality of storage slots 61 for placing magnetic sheets 71.

[0071] When the feeding mechanism 3 malfunctions, the storage tray 60 serves as a temporary placement. A portion of magnetic sheets 71 can also be placed in the storage tray 60 in advance. When the pallet 11 of the feeding mechanism 1 has completed the feeding of all magnetic sheets 71, the transfer mechanism 2 will pick up the magnetic sheets 71 from the storage tray 60 during the time interval of changing the pallet 11, thereby ensuring the continuity of production.

[0072] like Figure 7 and Figure 9As shown, this embodiment also includes a second servo motor 80 and a rotating frame 81. The second servo motor 80 is set on the workbench 6, located below the pushing mechanism 3. The output end of the second servo motor 80 is set vertically upward. The rotating frame 81 is set on the output end of the second servo motor. The rotating frame 81 is provided with a plurality of storage stations 82. The storage fixture 5 is set on the storage station 82.

[0073] In this embodiment, the second servo motor 80 can drive the rotating frame 81 to rotate, so that the storage fixtures 5 on each storage station 82 rotate synchronously to the position corresponding to the pushing mechanism 3. In order to improve the filling efficiency of the magnetic sheet 71, the rotating frame 81 in this embodiment is provided with four storage stations 82 and two pushing mechanisms 3, but it is not limited to this. In other embodiments, it can also be set according to the actual situation.

[0074] like Figure 7 and Figure 9 As shown, this embodiment also includes a first lifting cylinder 84 and a third servo motor 85. The first lifting cylinder 84 is mounted on the worktable 6, and its output end is arranged vertically. The third servo motor 85 is mounted on the output end of the first lifting cylinder 84. A bearing 83 is provided on the storage station 82, and the storage fixture 5 is fixedly mounted on the inner ring of the bearing 83. A turntable 86 is provided on the output end of the third servo motor 85. The turntable 86 and the bottom of the storage fixture 5 are positioned by a limiting block and a limiting groove. The third servo motor 85 is used to drive the storage fixture 5 to rotate around its own axis on the storage station 82, so that the multiple storage channels 50 of the storage fixture 5 correspond to the pushing channels 31 of the pushing mechanism 3 in turn.

[0075] Since the rotor 7 needs to be filled with multiple magnetic sheets 71, and since the rotor 7 is cylindrical, the positions of the multiple magnetic sheets 71 are also different. Therefore, in order to ensure that the magnetic sheets 71 are in the correct position when they are pressed into the rotor 7, in this embodiment, the storage fixture 5 is fixedly set in the inner ring of the bearing 83. The output end of the third servo motor 85 is provided with a turntable 86. The turntable 86 and the bottom of the storage fixture 5 are positioned by a limiting block and a limiting groove. The third servo motor 85 drives the storage fixture 5 to rotate around its own axis on the storage station 82, so that the storage fixture 5 can adjust the relative position relationship between the storage channel 50 and the pushing channel 31. At the same time, it can also make multiple storage channels 50 correspond to the pushing channel 31 of the pushing mechanism 3 in turn to facilitate the filling of multiple magnetic sheets 71.

[0076] In this embodiment, the storage fixture 5 is fixedly set in the inner ring of the bearing 83, and a turntable 86 is set at the output end of the third servo motor 85. The turntable 86 and the bottom of the storage fixture 5 are positioned by a limit block and a limit groove. The structure is simple and ensures that the magnetic sheet 71 is successfully loaded into the storage fixture 5.

[0077] like Figure 10 As shown, the storage channel 50 of the storage fixture 5 is provided with an elastic telescopic block 51 at the bottom. The elastic telescopic block 51 moves horizontally at the bottom of the storage channel 50. When the magnetic sheet 71 falls into the storage channel 50 of the storage fixture 5, the magnetic sheet 71 will not fall directly from the bottom of the storage channel 50 due to the blocking effect of the elastic telescopic block 51, ensuring that the subsequent pressing mechanism 4 can press the material smoothly.

[0078] In this embodiment, the elastic telescopic block 51 can be configured with a compression spring and a protrusion. Specifically, the storage fixture 5 can be radially provided with a sliding groove at the bottom of the storage channel 50, and the compression spring and the protrusion are slidably disposed in the sliding groove. In the default state, the compression spring continuously pushes the protrusion to close the storage channel 50. The top of the push block 311 can be provided with an inclined surface, so that when subjected to axial pressure, the protrusion slides radially in the sliding groove through the inclined surface and the compression spring, thereby opening the storage channel 50. This is something that those skilled in the art can achieve, and will not be elaborated further. Of course, other structures of the elastic telescopic block 51 can also be used in other embodiments.

[0079] like Figure 6 , Figure 11 and Figure 12 As shown, this embodiment also includes a second lifting cylinder 90 and a platform 91, and the pressing mechanism 4 includes a bracket 41, a third lifting cylinder 42 and a pressing rod 43;

[0080] The second lifting cylinder 90 and the bracket 41 are set on the workbench 6, located on one side of the rotating frame 81. The output end of the second lifting cylinder 90 is set vertically upward and is provided with a platform 91. Multiple positioning rods 92 are provided on the platform 91. The rotor 7 is provided with multiple positioning through holes 72. The rotor 7 is placed on the platform 91, and the positioning rods 92 pass through the positioning through holes 72. The top of the rotor 7 is positioned with the bottom of the storage fixture 5 by means of a limiting block and a limiting groove.

[0081] The third lifting cylinder 42 is mounted on the bracket 41. The output end of the third lifting cylinder 42 is set vertically downward. The pressure rod 43 is set at the output end of the third cylinder to form the pressing component 40. The third lifting cylinder 42 is used to drive the pressure rod 43 to extend from the top of the storage fixture 5 into the storage channel 50 and press the magnetic sheet 71 in the storage channel 50 from the bottom of the storage fixture 5 into the loading groove 70 corresponding to the rotor 7.

[0082] In this embodiment, taking the manual placement of the rotor 7 as an example, the platform 91 at the output end of the second lifting cylinder 90 is equipped with multiple positioning rods 92. When placing the rotor 7, the positioning rods 92 are passed through the positioning through holes 72 to complete the positioning of the rotor 7 on the platform 91. The rotating frame 81 can rotate the storage fixture 5 filled with magnetic sheets 71 to the position of the platform 91. The second lifting cylinder 90 drives the platform 91 to move upward. The top of the rotor 7 and the bottom of the storage fixture 5 are positioned by a limiting block and a limiting groove, so that the loading slot 70 of the rotor 7 corresponds one-to-one with the storage channel 50 of the storage fixture 5. Then, the third lifting cylinder 42 drives the pressure rod 43 to extend from the top of the storage fixture 5 into the storage channel 50, and presses the magnetic sheets 71 in the storage channel 50 from the bottom of the storage fixture 5 into the loading slot 70 corresponding to the rotor 7. In this embodiment, multiple pressure rods 43 can be provided, each pressure rod 43 corresponding to one storage channel 50 of the storage fixture 5, such as Figure 13 As shown, multiple pressure rods 43 can press the magnetic sheet 71 of the storage channel 50 into the loading slot 70 of the rotor 7 in one go, thereby improving assembly efficiency.

[0083] In addition, this embodiment also includes an inspection station, which is equipped with a pressing mechanism 4. After the magnetic sheet 71 of the storage channel 50 of the storage fixture 5 is pressed into the loading slot 70 of the rotor 7 in one go, the rotating frame 81 continues to drive the storage fixture 5 to rotate to the inspection station. At this time, the third lifting cylinder 42 of the inspection station will continue to drive the pressing rod 43 to extend from the top of the storage fixture 5 into the storage channel 50 to check whether there are still magnetic sheets 71 in the storage fixture 5, so as to ensure the smooth assembly of the magnetic sheets 71 in the future.

[0084] Of course, to further improve production efficiency, in other embodiments, an assembly line can be set up to transport the rotor 7. When the assembly line transports the second lifting cylinder 90, the platform 91, and the rotor 7 to the designated position, the assembly line stops working. Then, the second lifting cylinder 90 drives the platform 91 and the rotor 7 to move upward to assemble the magnetic sheet 71. After the assembly is completed, the second lifting cylinder 90 drives the platform 91 and the rotor 7 to move downward. The rotor 7, with the magnetic sheet 71 assembled, continues to flow with the assembly line to the next process.

[0085] The working process of this embodiment is as follows:

[0086] The magnetic sheet 71 is pre-placed in the tray 11 of the feeding mechanism 1. The industrial robot 20 of the transfer mechanism 2, together with the clamping cylinder 21 and the gripper 22, transports multiple magnetic sheets 71 to the feeding track 32 of the pushing mechanism 3.

[0087] The first pushing cylinder 33 of the pushing mechanism 3 pushes multiple magnetic pieces 71 from the feeding channel 30 into the baffle groove 36. The first servo motor 37 drives the baffle block 34 to rotate clockwise between the two limiting baffles 38, causing the multiple magnetic pieces 71 in the baffle groove 36 to rotate to the position of the limiting slide groove 39. The second pushing cylinder 310 drives the push block 311 to push the multiple magnetic pieces 71 in the baffle groove 36, and the magnetic piece 71 at the foremost end of the pushing direction of the push block 311 abuts against the limiting slide groove 39. Then, the third pushing cylinder 312 drives the push rod 314 through the connecting plate 313 to extend from the upper end of the limiting slide groove 39 and push the magnetic piece 71 in the limiting slide groove 39 out from the lower end of the limiting slide groove 39, so that the magnetic piece 71 falls into a storage channel 50 of the storage fixture 5 at the lower end of the limiting slide groove 39. This process is repeated until all the magnetic pieces 71 in the stop groove 36 are pushed into the storage channel 50 of the storage fixture 5. When the magnetic piece 71 falls into the storage channel 50 of the storage fixture 5, it will not fall directly from the bottom of the storage channel 50 due to the blocking effect of the elastic telescopic block 51.

[0088] The second servo motor 80 drives the rotating frame 81 to rotate, causing the storage fixtures 5 on each storage station 82 to rotate sequentially to the positions corresponding to the limiting grooves 39 of the pushing mechanism 3, so as to load the magnetic sheets 71 in turn. At the same time, the third servo motor 85 drives the turntable 86 to move upward. The turntable 86 and the bottom of the storage fixture 5 are positioned by limiting blocks and limiting grooves. The third servo motor 85 drives the storage fixture 5 to rotate around its own axis on the storage station 82, so that the storage fixture 5 can adjust the relative positional relationship between the storage channel 50 and the pushing channel 31.

[0089] The rotating frame 81 rotates the storage fixture 5, which is filled with magnetic sheets 71, to the platform 91. Multiple positioning rods 92 are provided on the platform 91 at the output end of the second lifting cylinder 90. When placing the rotor 7, the positioning rods 92 pass through the positioning through holes 72 to position the rotor 7 on the platform 91. The second lifting cylinder 90 drives the platform 91 upwards. The top of the rotor 7 is positioned with the bottom of the storage fixture 5 by a limiting block and a limiting groove, ensuring that the loading slot 70 of the rotor 7 corresponds one-to-one with the storage channel 50 of the storage fixture 5. Then, the third lifting cylinder 42 drives the pressure rod 43 to extend from the top of the storage fixture 5 into the storage channel 50, pressing the magnetic sheets 71 in the storage channel 50 from the bottom of the storage fixture 5 into the corresponding loading slot 70 of the rotor 7, completing the assembly of the magnetic sheets 71 on the rotor 7.

[0090] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0091] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
