Description

Technical Field

[0001] This invention relates to the field of motor stator manufacturing technology, and more specifically, to an automatic assembly machine for stator end rings and inner support components. Background Technology

[0002] In the assembly process of stator end rings, existing technologies often employ step-by-step manual or semi-automatic methods to complete processes such as gluing, magnet pressing, and end ring pressing. This results in low production efficiency, dispersed processes, and a tendency for accumulated positioning errors, leading to low relative positional accuracy between the end ring and the magnet. Furthermore, while some automated equipment can achieve multi-station assembly, the assembly of end rings often involves only axial pressing and adhesive bonding followed by direct curing. However, due to the poor initial bonding stability between the end ring and the adhesive, loosening and deformation can easily occur during curing due to stress release or adhesive shrinkage. Moreover, the lack of a structure that provides uniform support for the magnet makes it difficult to guarantee the positional accuracy between the end ring and the magnet, resulting in poor assembly quality and affecting the overall structural stability and consistency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automatic assembly machine for stator end rings and inner support components, in view of the above-mentioned defects of the prior art.

[0004] The technical solution adopted by this invention to solve its technical problem is: an automatic assembly machine for stator end rings and inner support components, including a machine base, on which a jig, an adhesive application module, an inner support assembly module, a magnet pressing module, an inner support pressing module, an end ring assembly module, and an end environmental protection pressing module are provided. The jig is slidably mounted on the machine base and moves back and forth between the adhesive application module, the inner support assembly module, the magnet pressing module, the inner support pressing module, the end ring assembly module, and the end environmental protection pressing module. The adhesive application module, the inner support assembly module, the magnet pressing module, the inner support pressing module, the end ring assembly module, and the end environmental protection pressing module are respectively used to perform corresponding processes on the stator on the jig. The end environmental protection pressing module includes a pressure holding mechanism, which is used to extend into the end ring on the stator and apply radial supporting force thereto.

[0005] In some embodiments, the pressure holding mechanism is provided in at least three sets, and the at least three sets of pressure holding mechanisms are distributed at intervals along a direction perpendicular to the moving direction of the fixture; the end environmental pressure module also includes at least three support platforms, and the at least three support platforms correspond one-to-one with the at least three sets of pressure holding mechanisms and are located below the corresponding pressure holding mechanisms; the machine base is also provided with a transfer module, which is used to transfer the stator on the fixture to any one of the support platforms or to transfer the stator on any one of the support platforms to the fixture.

[0006] In some embodiments, the pressure holding mechanism includes a linear slide rail fixed vertically on the machine base, a slider sliding on the linear slide rail, a first pressure plate fixed on the slider, and a first pressure head fixed on the bottom surface of the first pressure plate; the outer diameter of the first pressure head is adapted to the inner diameter of the end ring so as to extend into the end ring and apply radial resistance force thereto.

[0007] In some embodiments, the machine base is further provided with an inner support material distribution module, which is located close to the inner support module, and the discharge side of the inner support material distribution module corresponds to the material taking side of the inner support module.

[0008] In some embodiments, the internal support material distribution module includes a first material rack fixedly mounted on a machine base. The first material rack is provided with a first storage plate and a first discharge plate that are parallel to each other. The first storage plate is fixedly mounted, and the top surface of the first storage plate is provided with a stacking area for stacking and storing a plurality of internal support components. The first discharge plate is slidably mounted and located below the first storage plate. The top surface of the first discharge plate is provided with a single material placement slot for receiving a single internal support component. The first storage plate is provided with a discharge through hole corresponding to the single material placement slot.

[0009] In some embodiments, a gap is provided between the first storage plate and the first discharge plate, the gap being greater than the thickness of a single inner support assembly.

[0010] In some embodiments, the depth of the single material placement slot is less than or equal to half the thickness of a single inner support component.

[0011] In some embodiments, the top surface of the first storage plate is further provided with a plurality of limiting posts, and the plurality of limiting posts are distributed around the stacking and unloading area at equal intervals.

[0012] In some embodiments, the internal support module includes a Y-axis drive mechanism fixedly mounted on the machine base, a Z-axis drive mechanism fixedly mounted on the sliding end of the Y-axis drive mechanism, and a material handling clamping mechanism fixedly mounted on the sliding end of the Z-axis drive mechanism.

[0014] The beneficial effects of this invention are as follows: Unlike the prior art, the automatic assembly machine for stator end rings and inner support components of this invention, through the back-and-forth movement of the fixture between the glue application module, the inner support assembly module, the magnet pressing module, the inner support pressing module, the end ring assembly module, and the end ring pressing module, feeds the stator into the glue application, inner support assembly, magnet pressing, inner support pressing, end ring assembly, and end ring pressing process, realizing continuous automated assembly of the stator end rings and inner support components; the inner support components uniformly support the magnets under the flattening effect of the inner support pressing module; after the end rings are installed, the pressure holding mechanism of the end ring pressing module extends into the end ring and applies radial resistance force to it, so that the end rings are tightly attached to the magnets and maintain stable pressure, thereby facilitating subsequent curing treatment, making the end rings less prone to loosening or deformation, effectively improving assembly accuracy and structural stability, and significantly improving production efficiency and product consistency.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0021] This invention provides an automatic assembly machine for stator end rings and inner support components, such as... Figure 1As shown, the automatic assembly machine for stator end rings and inner support components includes a machine base 1. The machine base 1 is equipped with a fixture 2, an adhesive application module 3, an inner support assembly module 4, a magnet pressing module 5, an inner support pressing module 6, an end ring assembly module 7, and an end environmental protection pressing module 8. The fixture 2 is slidably mounted on the machine base 1 and moves back and forth between the adhesive application module 3, the inner support assembly module 4, the magnet pressing module 5, the inner support pressing module 6, the end ring assembly module 7, and the end environmental protection pressing module 8. The adhesive application module 3, the inner support assembly module 4, the magnet pressing module 5, the inner support pressing module 6, the end ring assembly module 7, and the end environmental protection pressing module 8 are respectively used to perform corresponding processes on the stator on the fixture 2. The end environmental protection pressing module 8 includes a pressure holding mechanism 81, which is used to extend into the end ring on the stator and apply radial resistance force to it.

[0022] The automatic assembly machine for stator end rings and inner support components in this embodiment of the invention uses a fixture 2 to move back and forth between the glue application module 3, the inner support installation module 4, the magnet pressing module 5, the inner support pressing module 6, the end ring installation module 7, and the end ring pressing module 8. This allows the stator to be fed into the glue application, inner support installation, magnet pressing, inner support pressing, end ring installation, and end ring pressing process, achieving continuous automated assembly of the stator end rings and inner support components. The inner support components uniformly support the magnets under the flattening effect of the inner support pressing module 6. After the end rings are installed, the pressure holding mechanism 81 of the end ring pressing module 8 extends into the end ring and applies radial resistance force to it, making the end ring tightly adhere to the magnets and maintaining stable pressure, which helps with subsequent curing processes and prevents the end rings from loosening or deforming.

[0023] Specifically, in this embodiment, as Figure 2 As shown, the pressure holding mechanism 81 has at least three sets, which are distributed at intervals along a direction perpendicular to the moving direction of the fixture 2. The end ring pressure holding module 8 also includes at least three support platforms 82, which correspond one-to-one with the at least three sets of pressure holding mechanisms 81 and are located below the corresponding pressure holding mechanisms 81, for supporting the stator and aligning the end ring with the pressure holding mechanism 81. The machine tool 1 is also provided with a transfer module 13, which is used to transfer the stator on the fixture 2 to any one of the support platforms 82 or to transfer the stator on any one of the support platforms 82 to the fixture 2, realizing flexible scheduling of the fixture 2 and the pressure holding station, thereby improving the production line cycle time and process connection efficiency.

[0024] The pressure holding mechanism 81 includes a linear slide rail 811 fixed vertically on the machine base 1, a slider 812 sliding on the linear slide rail 811, a first pressure plate 813 fixed on the slider 812, and a first pressure head 814 fixed on the bottom surface of the first pressure plate 813. The slider 812 is driven to slide by a servo motor. The outer diameter of the first pressure head 814 is adapted to the inner diameter of the end ring so as to extend into the end ring and apply radial resistance force thereto. The holding time of the first pressure head 814 in the end ring should be no less than 2 seconds, so that the end ring can generate an initial adhesive force with the magnet through adhesive bonding, and the two maintain a stable connection for a slightly longer period of time to facilitate subsequent curing treatment.

[0025] Specifically, in this embodiment, as Figure 3 As shown, the machine tool 1 is also equipped with an inner support distribution module 9, which is located close to the inner support assembly module 4. The discharge side of the inner support distribution module 9 corresponds to the picking side of the inner support assembly module 4. The inner support distribution module 9 is used to separate and transport several stacked inner support components one by one to the picking position of the inner support assembly module 4, so as to ensure that the inner support assembly module 4 can continuously and accurately pick up the inner support components for assembly.

[0026] The internal support material distribution module 9 includes a first material rack 91 fixedly mounted on the machine base 1. The first material rack 91 has a first storage plate 92 and a first discharge plate 93 that are parallel to each other. The first storage plate 92 is fixedly mounted, and its top surface has a stacking area for vertically stacking several internal support components. The first discharge plate 93 is slidably mounted below the first storage plate 92 and is driven to slide by a servo motor assembly. Its top surface has a single-material placement slot for receiving individual internal support components falling from the stacking area. Therefore, the first storage plate 92 has a discharge through-hole corresponding to the single-material placement slot, allowing the internal support components to fall into the slot one by one. The size of the discharge through-hole is designed to allow the internal support components to fall into the slot one by one.

[0027] A gap is left between the first storage plate 92 and the first discharge plate 93, the gap being greater than the thickness of a single inner support component, to ensure that the inner support components can fall smoothly one by one without jamming. The depth of the single material placement groove is less than or equal to half the thickness of a single inner support component, thereby preventing the inner support component from tilting or falling out in the groove and ensuring the stability and accuracy of the discharge position.

[0028] Specifically, in this embodiment, the top surface of the first storage plate 92 is also provided with a number of limiting posts 94. The number of limiting posts 94 are distributed around the stacking and feeding area at equal intervals to constrain the stacked internal support components, so that they remain neatly arranged during storage and separation, and prevent the stacking from shifting due to shaking or external force, which would affect the accuracy of single-piece separation.

[0029] It should be noted that, in this embodiment, the first storage plate 92 should also be provided with a limiting mechanism at a suitable position near the unloading through hole or the stacking and unloading area to restrict the fall of several upper inner support components. This mechanism is used to restrict the second to last inner support component from falling during the unloading process in the stacking and unloading area, so as to ensure that only one inner support component enters the single material placement slot at a time. Since the application of this limiting mechanism is common in the prior art, in actual application, any suitable limiting mechanism in the prior art can be used for layout. This embodiment does not make specific limitations.

[0030] Furthermore, in this embodiment, as Figure 4 As shown, the machine tool 1 is also equipped with an end ring distribution module 10, which is located close to the end ring assembly module 7. The discharge side of the end ring distribution module 10 corresponds to the picking side of the end ring assembly module 7. The end ring distribution module 10 is used to separate and transport several stacked end rings one by one to the picking position of the end ring assembly module 7, so as to ensure that the end ring assembly module 7 can continuously and accurately pick up the end rings for assembly. It should be noted that the end ring distribution module 10 includes a second material rack 101, a second storage plate 102, and a second discharge plate 103, etc. Its specific structural layout is similar to that of the internal support distribution module 9. In actual application, the description of the internal support distribution module 9 mentioned above can be referred to, and will not be repeated here. In some other embodiments, the specific structural layout of the end ring distribution module 10 may also adopt other suitable layouts, which should be based on the actual application.

[0031] Specifically, in this embodiment, as Figure 5 As shown, the internal support module 4 includes a Y-axis drive mechanism 41 fixedly mounted on the machine base 1, a Z-axis drive mechanism 42 fixedly mounted on the sliding end of the Y-axis drive mechanism 41, and a material-grabbing clamping mechanism 43 fixedly mounted on the sliding end of the Z-axis drive mechanism 42. The material-grabbing clamping mechanism 43 is, for example, a three-jaw material-grabbing mechanism driven by a three-jaw cylinder. The Y-axis drive mechanism 41 drives the Z-axis drive mechanism 42 to move back and forth along the front-rear direction of the machine base 1, and the Z-axis drive mechanism 42 drives the material-grabbing clamping mechanism 43 to move vertically, thereby enabling the grabbing of a single internal support component from the internal support distribution module 9 and its precise installation into a predetermined position inside the stator. It should be noted that the specific structural layout of the end ring module 7 is similar to that of the internal support module 4. In actual applications, the description of the internal support module 4 described above can be used, and will not be repeated here. In other embodiments, the specific structural layout of the end ring module 7 may also adopt other suitable layouts, and the actual application shall prevail.

[0032] Specifically, in this embodiment, as Figure 6As shown, the inner support module 6 includes a hydraulic mechanism 61 fixedly mounted on the machine base 1, a second pressure plate 62 fixedly mounted on the movable end of the hydraulic mechanism 61, and a second pressure head 63 fixedly mounted on the bottom surface of the second pressure plate 62; the outer contour shape of the second pressure head 63 matches the shape of the inner support assembly to flatten the inner support assembly. Wherein, as... Figure 7 As shown, the inner support assembly includes an outer ring 1001 and an inner support block 1002 that fits within the outer ring 1001. The inner wall of the outer ring 1001 and the outer wall of the inner support block 1002 are designed with a tapered self-locking angle. Pressing down on the inner support block 1002 expands the outer ring 1001, thereby supporting the magnet through the outer ring 1001. Therefore, the outer contour shape of the second pressure head 63 should specifically match the shape of the inner support block 1002. When the hydraulic mechanism 61 drives the second pressure plate 62 downward, the second pressure head 63 presses on the inner support block 1002, expanding the outer ring 1001 through the inner support block 1002. This ensures that the outer ring 1001 fits tightly against the inner circumferential side of the magnet to support the magnet, ensuring that the magnet maintains the correct shape and position during subsequent end ring installation and pressure holding processes. It should be noted that the specific structural layout of the magnet module 5 is similar to that of the internal support module 6. In actual applications, the description of the internal support module 6 described above can be used, and will not be repeated here. In some other embodiments, the specific structural layout of the magnet module 5 may also adopt other suitable layouts, and the actual application shall prevail.

[0033] Furthermore, in this embodiment, as Figure 1 As shown, the machine tool 1 is also equipped with a feeding and conveying module, which includes a movable feeding platform 10 and a double-speed moving mechanism 11. The feeding platform 10 is fixedly mounted on the drive end of the double-speed moving mechanism 11. The double-speed moving mechanism is used to drive the feeding platform 10 to move at a preset required speed for material retrieval. By presetting the required speed, the double-speed moving mechanism 11 can flexibly adjust the moving speed of the feeding platform 10 according to assembly requirements and the processing speed of subsequent workstations. This helps to reduce the idle stroke and waiting time of the feeding platform 10, thereby improving the efficiency of the feeding process and ensuring the smooth operation and positioning accuracy of the feeding platform 10. The double-speed moving mechanism 11 can be, for example, a double-speed chain conveyor.

[0034] Among them, such as Figure 1As shown, the machine base 1 is also equipped with a linear motion mechanism 12. The fixture 2 is fixedly mounted on the drive end of the linear motion mechanism 12. The linear motion mechanism 12 is used to drive the fixture 2 to move according to the processing steps to the glue application module 3, the inner support module 4, the magnet pressing module 5, the inner support pressing module 6, the end ring installation module 7, or the end ring pressing module 8. Specifically, the double-speed movement mechanism 11 and the linear motion mechanism 12 are horizontally distributed front and back, that is, the double-speed movement mechanism 11 is located in front of the linear motion mechanism 12, and the double-speed movement mechanism 11 is parallel to the linear motion mechanism 12. The movement directions of the loading platform 10 and the fixture 2 are parallel to each other. In addition, the side of the linear motion mechanism 12 closest to the glue application module 3 extends out of the machine base 1 so that the fixture 2 can continue to move outward along its extension. This is based on the consideration that multiple glue application processes need to be performed. Currently, after the stator undergoes initial inner circumferential gluing and internal support installation, it needs to be transported to the magnetizing equipment for magnetizing. Then, it needs to be transported back to the magnet pressing module 5 to flatten all the magnets. Therefore, a design is adopted where the linear motion mechanism 12 extends outward from the side closest to the gluing module 3. This allows the fixture 2 to continue moving to the magnetizing station of the magnetizing equipment without further transport. This not only strengthens the coordination with other magnetizing equipment but also helps optimize the gluing process, making the overall operation simpler. It should be noted that the outward extension distance of the linear motion mechanism 12 is based on meeting the aforementioned requirements for the movement of the fixture 2; no specific limitation is made here. The linear motion mechanism 12 can be, for example, a high-precision movement mechanism composed of a servo motor, a ball screw (or synchronous belt), and a linear guide.

[0035] In this arrangement, the glue-applying module 3, the inner support module 4, the magnet-pressing module 5, the inner support-pressing module 6, the end ring-installing module 7, and the end environmental protection pressing module 8 are arranged in an orderly manner along the length of the linear moving mechanism 12 according to the layout shown in the figure. In other embodiments, the glue-applying module 3, the inner support module 4, the magnet-pressing module 5, the inner support-pressing module 6, the end ring-installing module 7, and the end environmental protection pressing module 8 may also be arranged in an orderly manner according to other suitable layouts. The attached figures are for illustrative purposes only.

[0036] The transfer module 13 spans the speed-multiplying moving mechanism 11, the linear moving mechanism 12, and at least three pressure-holding mechanisms 81. It can transfer the stator from the loading platform 10 to the fixture 2, and also perform stator transfer operations between the fixture 2 and the at least three pressure-holding mechanisms 81. This not only saves space but also improves transfer efficiency, effectively coordinating processing cycles to ensure production efficiency. The transfer module 13, for example, also adopts a structure layout with a Y-axis drive mechanism 41, a Z-axis drive mechanism 42, and a picking gripper working in coordination, similar to the internal support module 4, to achieve stator transfer.

[0037] Furthermore, in this embodiment, as Figure 1As shown, the machine tool 1 is also equipped with a vision inspection module 14. The vision inspection module 14 is located on the side of the linear motion mechanism 12 away from the glue application module 3 and corresponds to the glue application module 3. It is used to perform visual inspection on the stator on the fixture 2 to ensure controllable assembly quality. The vision inspection module 14 includes a vision inspection camera, used to detect whether the glue application is uniform and whether the assembly is in place. The vision inspection camera is, for example, a CCD camera.

[0038] It should be noted that in this embodiment, any suitable existing automated glue application device can be used for the glue application module 3, as long as it can realize the automatic glue application operation. This embodiment does not make specific limitations, and the attached drawings are only examples.

[0039] Furthermore, in this embodiment, as Figure 1 As shown, a material handling module 15 is also provided on one side of the machine base 1 to promptly transfer the assembled stator to the next processing station or to the discharge station after the end ring assembly is completed. The material handling module 15 can be any suitable existing technology, as long as it can achieve the purpose of material handling; no specific limitation is made here.

[0040] The stator end ring and inner support assembly automatic assembly machine according to the present invention involves feeding the stator through the feeding and conveying module and transferring it to the fixture 2 by the transfer module 13. First, it enters the gluing module 3 to apply glue to the inner side of the stator housing. Then, it is moved to the inner support assembly module 4, where the inner support distribution module 9 supplies individual inner support assemblies, which are then gripped and installed by the material handling clamping mechanism 43. Next, it is transferred to the magnet insertion equipment to complete the magnet insertion process. Then, it enters the magnet pressing module 5 to flatten all the magnets, and finally enters the inner support pressing module 6, where it is pressed tightly by the second pressing head 63. The inner support component evenly supports the magnet; then it enters the glue application module 3 again, where glue is applied again to the inner step formed by the magnet and the inner support component. Then it enters the end ring installation module 7, where the end ring is installed at the inner step formed by the glued magnet and the inner support; finally, it enters the end ring pressure module 8, where the first pressure head 814 of any pressure holding mechanism 81 extends into the end ring to apply radial resistance force, making the end ring tightly adhere to the magnet and the inner support, thereby ensuring the curing quality. The entire process is highly automated, and the assembly accuracy and efficiency are significantly improved.

[0041] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
