[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] See also Figure 1 and Figure 2Now, the processing device of the stator core provided by the present invention is described. The processing device includes a frame, a workbench 2, a feeding mechanism 3, and a preliminary rounding mechanism 4, a turntable 5, a fine rounding mechanism 6 and a welding mechanism 8 arranged on the workbench 2; the feeding mechanism 3 extends along the second direction 30, and is used to drive the product to be transported, such as the divided or rounded stator core, to move along the second direction 30, one end of which is a feeding end, and the other end is a unloading end. The workbench 2 and the feeding mechanism 3 are arranged side by side on the frame in the first direction 20, that is, the workbench 2 is located on one side of the feeding mechanism 3; the initial rounding mechanism 4 and the turntable 5 are arranged at intervals along the second direction 30 on the workbench 2, and the initial rounding mechanism 4 is located near the feeding end, and is used to clamp the segmented iron cores transported by the feeding mechanism 3 to preliminarily round the segmented iron cores into round iron cores, and the turntable 5 is used to place multiple round iron cores after initial rounding, and the turntable 5 rotates relative to the workbench 2 with a straight line parallel to the third direction 40 as the axis; the fine rounding mechanism 6 and the welding mechanism 8 are arranged at intervals in the circumferential direction of the turntable 5, and the fine rounding mechanism 6 is used to further round the round iron cores on the turntable 5, and the welding mechanism 8 is used to weld the round iron cores further rounded by the fine rounding mechanism 6.

[0029] It should be noted that the first direction 20 and the second direction 30 are not parallel. Preferably, the first direction 20 and the second direction 30 are perpendicular, and the third direction 40 is perpendicular to the first direction 20 and the second direction 30 .

[0030] In a specific implementation, one end of the feeding mechanism 3 can be a feeding end, and the other end can be a unloading end. Before feeding, each block core can be scanned by a scanning component (not shown) located at the feeding end of the feeding mechanism 3 to save relevant parameters of each block core. The feeding mechanism 3 loads multiple block cores from the feeding end and transports them along the second direction 30. The initial rounding mechanism 4 clamps the block cores transported by the feeding mechanism 3 and initially rounds the block cores into round cores. The initially rounded cores can be placed on the turntable 5 by a manipulator, and a rotation direction along the turntable 5 can be set on the turntable 5. There are multiple workstations evenly distributed in the circumferential direction, each of which is used to place a round core. The turntable 5 rotates relative to the worktable 2 with a straight line parallel to the third direction 40 as the axis, so that a round core corresponds to the fine rounding mechanism 6. The fine rounding mechanism 6 further rounds the round core, and then the turntable 5 is rotated to rotate the next round core that has been initially rounded to correspond to the fine rounding mechanism 6. At the same time, the round core that has been further rounded by the fine rounding mechanism 6 arrives at the position corresponding to the welding mechanism 8 after the turntable 5 rotates, and is welded. Finally, the round core that has been welded is cut. Before the fine rounding mechanism 6 further rounds the round core, the round core can be photographed to prevent the round core from missing part of the block core.

[0031] In the processing device provided in the embodiment of the present application, since the workbench 2 and the feeding mechanism 3 are arranged side by side on the frame in the first direction 20, the initial circular assembly mechanism 4 and the turntable 5 are arranged at intervals along the second direction 30 on the workbench 2, thereby avoiding the problem of excessive length dimensions and excessive volume occupied due to the linear arrangement of multiple mechanisms of the processing device; and, after the welding of the assembled circular core is completed, at the welding station, the position of the assembled circular core is close to the discharge end, and the feeding mechanism 3 can be used to realize the movement of the block core and the assembled circular core in the second direction 30 until the assembled circular core is unloaded, that is, the feeding mechanism 3 can also have the function of unloading, thereby simplifying the structure of the processing device and reducing the volume of the processing device.

[0032] Compared with the prior art, the stator core processing device provided by the present invention has a workbench 2 and a feeding mechanism 3 arranged side by side on a frame in a first direction 20, the feeding mechanism 3 transports multiple segmented cores along a second direction 30, the initial rounding mechanism 4 and the turntable 5 are arranged at intervals along the second direction 30 on the workbench 2, and then the fine rounding mechanism 6 and the welding mechanism 8 are arranged at intervals in the circumferential direction of the turntable 5, avoiding a simple linear layout, so that the stator core processing device has a compact structure and a reasonable layout; at the same time, the feeding mechanism 3 can also have the function of unloading, which can reduce the volume of the stator core processing device as a whole, thereby reducing the space occupied by the stator core processing device.

[0033] In one embodiment, the feeding mechanism 3 includes a conveying assembly 31, a tray 32 and a lifting assembly 33. At the feeding end, the tray 32 is used to accommodate a plurality of segmented cores. The tray 32 is placed on the conveying assembly 31. The conveying assembly 31 is used to transport the tray 32 in the second direction 30. The conveying assembly 31 is provided with a first through hole 34 that passes through along the third direction 40, and the first through hole 34 extends along the second direction 30. One end of the lifting assembly 33 is located on the side of the conveying assembly 31 away from the tray 32. The other end of the lifting assembly 33 passes through the first through hole 34 and can move along the third direction 40 to push the tray 32 away from the conveying assembly 31. In the prior art, the feeding mechanism 3 of the segmented core is usually provided with a material warehouse for storing the segmented cores. When the processing device of the stator core needs the segmented cores, the segmented cores in the material warehouse need to be loaded into the processing device. Due to the setting of the material warehouse, the volume of the feeding mechanism 3 is very large, thereby increasing the overall volume of the processing device. In this embodiment, there is no need to set up a material warehouse in the processing device. When the processing device needs segmented iron cores, the pallet 32 ​​with the segmented iron cores can be transported by a trolley, and then the pallet 32 ​​can be transported in the second direction 30 by the conveying assembly 31. When transported to the preset position, the lifting assembly 33 moves along the third direction 40 and passes through the first through hole 34 to push the pallet 32 ​​away from the conveying assembly 31, so that the pallet 32 ​​can stop moving in the second direction 30, thereby facilitating the initial circular mechanism 4 to clamp the segmented iron cores on the pallet 32; at the same time, since the first through hole 34 extends along the second direction 30, when the lifting assembly 33 moves along the third direction 40 and passes through the first through hole 34 to push the pallet 32 ​​away from the conveying assembly 31, it will not affect the continued transportation of the conveying assembly 31.

[0034] In one embodiment, a rotating member rotating about a straight line parallel to the third direction 40 can also be provided at the upper end of the jacking assembly 33, and the tray 32 is placed on the rotating member. When the segmented iron core is transported to a preset position, the jacking assembly 33 moves along the third direction 40 and passes through the first through hole 34 to push the tray 32 away from the conveying assembly 31. The rotating member drives the tray 32 to rotate, so that the segmented iron core rotates to the angle required by the initial circular mechanism 4. Multiple groups of jacking assemblies 33 can be provided, and multiple groups of jacking assemblies 33 are arranged at intervals along the second direction 30, so that the segmented iron cores on multiple trays 32 can be loaded at the same time.

[0035] In one embodiment, if Figure 3As shown, a cantilever 1 is provided on the frame, and a preset distance is set between the cantilever 1 and the workbench 2 in the third direction 40. The cantilever 1 can slide in the first direction 20 and the second direction 30 relative to the frame, and the initial rounding mechanism 4 is fixed on the cantilever 1. In specific implementation, when the feeding mechanism 3 transports the tray 32 with the segmented iron core to the preset position, the jacking assembly 33 moves along the third direction 40 and passes through the first through hole 34 to push the tray 32 away from the conveying assembly 31, and the cantilever 1 moves along the first direction 20 and the second direction 30, so that the initial rounding mechanism 4 can clamp the segmented iron core on the tray 32 and initially round the segmented iron core into a round iron core. By arranging the cantilever 1 on the frame and fixing the initial rounding mechanism 4 on the cantilever 1, the space utilization rate of the processing device can be improved, thereby making the layout of the processing device compact and reducing the overall size.

[0036] Furthermore, the initial circle forming mechanism 4 includes a clamping assembly 41 and a circle pushing assembly 42. The clamping assembly 41 is fixed to the cantilever 1, and the clamping assembly 41 clamps the multiple block cores transported by the feeding mechanism 3; the circle pushing assembly 42 is connected to the clamping assembly 41, and the circle pushing assembly 42 forms the multiple block cores on the clamping assembly 41 into a circle core. In specific implementation, the clamping assembly 41 may include multiple clamps, each clamp clamping a block core, and the circle pushing assembly 42 is used to push the block cores on the multiple clamps into a circle. The circle pushing assembly 42 can also directly push multiple block cores into a complete circle at one time, or it can first push the multiple block cores into multiple arcs separately, and then form the multiple arcs into a circle. This is not limited here, and those skilled in the art can choose the setting according to actual needs.

[0037] In addition, a plurality of workstations can be arranged on the workbench 2, each of which is used to place a preliminarily rounded iron core, and a rotating component can be arranged on each of the workstations.

[0038] Below, an example is given in which the number of clamping members in a clamping assembly 41 is three and a group of round cores includes twelve segmented cores. The clamping assembly 41 includes three clamping members spaced apart in the same direction, which can clamp three segmented cores at a time. The pushing assembly 42 can push two of the clamping members to rotate, driving two of the segmented cores to rotate, so that the three segmented cores form an arc. The three segmented cores forming an arc are placed on a workstation, and the clamping assembly 41 grabs another three segmented cores and pushes them into an arc by the pushing assembly 42, and then places them on the above-mentioned workstation until the group of twelve segmented cores on the workstation is completed. According to specific needs, two clamping assemblies 41 can also be provided, and the two clamping assemblies 41 can be spaced apart along the second direction 30, and the two clamping assemblies 41 can move synchronously, which can improve the efficiency of the grouping of the segmented cores.

[0039] In one embodiment, if Figure 4As shown, the fine assembly mechanism 6 includes a mold 61 and a press-fit assembly 62. The mold 61 is arranged on the turntable 5. The mold 61 includes an inner ring 611 and an outer ring 612 arranged on the turntable 5. The outer ring 612 is located outside the inner ring 611. An annular gap is formed between the inner ring 611 and the outer ring 612. The press-fit assembly 62 is used to press the assembled iron core into the annular gap along the third direction 40. In the prior art, the fine assembly usually adopts the method of pushing blocks to close, that is, multiple motors control multiple push blocks to close synchronously, each motor corresponds to a push block, and each push block corresponds to a segmented iron core. The synchronous movement of multiple motors can push the segmented iron cores to close synchronously, but in this method, the synchronization of multiple motors is difficult to control. In this embodiment, the press-fitting assembly 62 presses the assembled iron core after the initial rounding into the annular gap along the third direction 40, and the inner ring 611 and the outer ring 612 of the mold 61 are used to ensure the rounding accuracy of the assembled iron core. Compared with the method of closing the push blocks in the prior art, it has higher accuracy and can ensure the efficiency of fine rounding. At the same time, there is no need to use multiple motors, so that the structure of the fine rounding mechanism 6 is simpler and occupies less space. In specific implementation, the press-fitting assembly 62 can use a C-type press, and the turntable 5 is partially located in the C-type working chamber of the C-type press, which can make the structure of the processing device more compact.

[0040] After the assembled round iron core is pressed into the annular gap, the turntable 5 is rotated, and the assembled round iron core together with the mold 61 leave the working chamber of the press and arrive at the position of the welding mechanism 8, which is used to weld the assembled round iron core.

[0041] Furthermore, the processing device further includes a demoulding mechanism 7, and the fine rounding mechanism 6, the welding mechanism 8 and the demoulding mechanism 7 are sequentially arranged at intervals in the circumferential direction of the turntable 5, and the demoulding mechanism 7 is used to push the welded rounded iron core to leave the mold 61. That is, after the fine rounding of the rounded iron core is completed, it is also necessary to separate from the mold 61. Compared with the simple linear arrangement of the fine rounding mechanism 6, the welding mechanism 8 and the demoulding mechanism 7, the fine rounding mechanism 6, the welding mechanism 8 and the demoulding mechanism 7 are sequentially arranged at intervals in the circumferential direction of the turntable 5, which can reduce the overall size of the processing device, especially the size in the length direction, so that the layout of the processing device is more compact and the space size is more reasonable.

[0042] Specifically, Figure 5As shown, the demoulding mechanism 7 includes a first driving member 71, a demoulding body 72 and a demoulding member 73. The demoulding member 73 includes a plurality of push rods 731 extending along the third direction 40. Preferably, the number of the push rods 731 is the same as the number of the segmented iron cores in the mold 61. The first driving member 71 is provided on the demoulding body 72. The first driving member 71 is connected to the demoulding member 73, and drives the demoulding member 73 to move in the third direction 40, driving the push rods 731 to extend into the annular gap and push the assembled round iron core after welding to leave the mold 61. In specific implementation, after the assembled round iron core is welded, the turntable 5 is rotated to rotate the assembled round iron core together with the mold 61 to correspond to the demoulding mechanism 7. The first driving member 71 pushes the demoulding member 73 to move in the third direction 40, driving the push rods 731 to move in the third direction 40 and extend into the annular gap to push the assembled round iron core to leave the mold 61. Since the number of push rods 731 is the same as the number of segmented iron cores in the mold 61, that is, one push rod 731 can correspond to one segmented iron core, so as to ensure that the thrust of the push rod 731 on the welded assembled round iron core is balanced and of moderate force, when the first driving member 71 pushes the demolding member 73 to move in the third direction 40, multiple push rods 731 can synchronously push multiple segmented iron cores in the mold 61 to move together in the third direction 40 until they leave the mold 61.

[0043] In one embodiment, a second through hole 721 extending along a third direction 40 is formed at one end of the demolding body 72 away from the turntable 5, and a push rod 731 pushes the welded assembled round iron core to leave the mold 61 from the second through hole 721. The direction in which the push rod 731 pushes the assembled round iron core to move is opposite to the direction in which the press-fitting assembly 62 presses the assembled round iron core into the annular gap. In specific implementation, a second through hole 721 is opened at the upper end of the demolding body 72 and passes through the third direction 40. Here, only the Z direction is used as an example for explanation. The press-fitting component 62 presses the assembled round iron core into the annular gap in a downward direction, and the push rod 731 pushes the assembled round iron core to move in an upward direction. When demolding is required, the push rod 731 pushes the assembled round iron core to move upward, so that the assembled round iron core leaves the mold 61 from the second through hole 721. A unloading robot can be arranged above the demolding body 72. When the push rod 731 pushes the assembled round iron core from the second through hole 721 to the top of the demolding body 72, the unloading robot can grab the assembled round iron core and then place the assembled round iron core on the conveying component 31 near the unloading end for unloading. A cleaning structure can also be arranged above the turntable 5 to blow and vacuum the mold 61 after demolding, and then unload the mold 61.

[0044] In one embodiment, a third through hole (not shown) is provided on the turntable 5 and passes through the third direction 40. The assembled round iron core is located at the third through hole, and the diameter of the third through hole is smaller than the diameter of the assembled round iron core. The processing device also includes a second driving member 9 and a connecting member 10. The second driving member 9 is provided on the workbench 2, and the second driving member 9 is connected to the connecting member 10. The connecting member 10 is driven to move through the third through hole along the third direction 40 and push the mold 61 and the assembled round iron core to move together, so that the assembled round iron core and the welding mechanism 8 are in the same position in the third direction 40, so that the welding mechanism 8 can perform welding. In specific implementation, the weld extends along the third direction 40, and the second driving member 9 drives the connecting member 10 to move along the third direction 40, so that the welding mechanism 8 does not need to move in the third direction 40 during welding. Since the assembled round iron core has multiple welding positions, in order to improve welding efficiency, multiple welding mechanisms 8 are usually set to weld simultaneously. The welding mechanism 8 does not need to move in the third direction 40, which can simplify the structure of the welding mechanism 8 and reduce the overall volume of the processing device. Taking the case where there are two welding mechanisms 8 as an example, the two welding mechanisms 8 can be distributed along the circumferential direction of the turntable 5 with the connecting member 10, and the two welding mechanisms 8 are respectively located on both sides of the connecting member 10, so that the layout of the processing device can be compact. Specifically, a rotating member can also be provided on the connecting member 10, so that the assembled round iron core can rotate, so that the welding mechanism 8 can weld different welds; the welding mechanism 8 can use a fiber laser to improve welding efficiency.

[0045] In one embodiment, the processing device further includes a smoke exhaust mechanism disposed on the workbench 2, the smoke exhaust mechanism and the connecting member 10 are arranged relative to each other in the third direction 40, and the smoke exhaust mechanism is used to exhaust the smoke generated during the welding process, thereby preventing the smoke from affecting the welding.

[0046] In the stator core processing device provided by the present invention, the driving parts involved can all be motors or cylinders. Preferably, all driving parts are cylinders, and then all cylinders are gathered through an air valve, so that the entire processing device has only one air inlet and one air outlet, further simplifying the structure of the processing device.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
