Description

Technical Field

[0001] This invention relates to the field of motor magnet heating, specifically to a magnet assembly heating device and heating method. Background Technology

[0002] In the assembly process of magnetic tiles and housings, it is usually necessary to assemble the magnetic tiles with components such as the housing and then heat-treat the assembly to eliminate assembly stress, improve magnetic properties, or cure thermosetting materials. Existing technologies commonly use heating methods such as oven heating and resistance heating plates. However, these traditional heating methods have the following shortcomings: First, oven heating is a batch heating process, which is slow to heat up and slow to cool down, making it difficult to achieve continuous production. Furthermore, the heating of assemblies in the same batch is uneven, affecting the consistency of the assemblies.

[0003] Secondly, the direct contact between the resistance heating plate and the workpiece can easily cause localized overheating, and the heating element has a short lifespan and high maintenance costs. For magnetic tile assemblies, excessively high temperatures or rapid temperature rises may lead to performance degradation or even cracking of the magnetic tiles.

[0004] Third, most existing heating devices lack cooling designs for the fixtures. After receiving high-temperature assemblies, residual heat accumulates in the fixtures. When unheated assemblies are loaded into the fixtures again, this preheats the new assemblies, resulting in inconsistent heating start temperatures for different batches of assemblies and affecting process stability.

[0005] Fourth, it lacks a stepped heating function, making it difficult to meet the process requirements that require gradual heating and precise temperature control.

[0006] Therefore, it is necessary to provide a heating device and heating method for magnetic tile assembly. Summary of the Invention

[0007] The present invention provides a heating device and heating method for magnetic tile assemblies, which effectively solves the problems of uneven heating, poor heating effect and lack of cooling for the fixture in existing magnetic tile assemblies.

[0008] The technical solution adopted in this invention is: A magnetic tile assembly heating device includes a frame, an indexer mounted on the frame, a turntable fixedly mounted on the output end of the indexer, a worktable fixedly mounted on the outer shell of the indexer and located above the turntable, and several jigs circumferentially mounted on the turntable. It also includes a shell loading mechanism mounted on the frame, a heating mechanism mounted on the worktable, a unloading mechanism mounted on the frame, and a cooling mechanism mounted on the frame. The heating mechanism includes a first seat mounted on the worktable, a first guide rail vertically mounted on the first seat, a first frame slidably mounted on the first guide rail, a first cylinder mounted on the first seat for driving the first frame to rise and fall, and several heating components circumferentially mounted on the first frame. Each heating component includes a mounting plate mounted on the first frame and a spiral heating ring mounted on the mounting plate. The spiral heating ring is a hollow tube, and each end of the spiral heating ring is externally connected to a water connector.

[0009] Furthermore, there are three heating components, and the heating temperature gradient of the three heating components is set.

[0010] Furthermore, the heating mechanism also includes several infrared sensors mounted on the first frame, with each infrared sensor corresponding to one of the heating components.

[0011] Furthermore, the shell feeding mechanism includes a second base mounted on the frame, a second linear module A horizontally mounted on the second base, a second sliding frame fixedly mounted on the output end of the second linear module, a second cylinder horizontally mounted on the second sliding frame and parallel to the second linear module A, a second linear module B vertically fixedly mounted on the output end of the second cylinder, a second connecting frame mounted on the output end of the second linear module B, a second rotary cylinder mounted on the second connecting frame, and a second cylinder gripper mounted on the output end of the second rotary cylinder.

[0012] Furthermore, the feeding mechanism includes a flipping and picking assembly and a transfer assembly mounted on the frame. The flipping and picking assembly includes a No. 3 base mounted on the frame, a No. 3 guide rail A horizontally mounted on the No. 3 base, a No. 3 slide block A slidably mounted on the No. 3 guide rail, a No. 3 cylinder A mounted on the No. 3 base for driving the No. 3 slide block A to slide along the No. 3 guide rail A, a No. 3 guide rail B vertically mounted on the No. 3 slide block A slidably mounted on the No. 3 guide rail B, a No. 3 cylinder B mounted on the No. 3 slide block A for driving the No. 3 slide block B to rise and fall along the No. 3 guide rail B, a No. 3 rotary cylinder mounted on the No. 3 slide block B, and a third cylinder gripper mounted at the output end of the No. 3 rotary cylinder.

[0013] Furthermore, the transplanting assembly includes a No. 4 base mounted on the frame, a No. 4 guide rail A horizontally mounted on the No. 4 base, a No. 4 slide mounted on the No. 4 guide rail A, a No. 4 linear module A mounted on the No. 4 base for driving the No. 4 slide along the No. 4 guide rail A, a No. 4 linear module B horizontally mounted on the No. 4 slide and perpendicular to the No. 4 guide rail A, a No. 4 linear module C vertically mounted at the output end of the No. 4 linear module B, a No. 4 lifting frame mounted at the output end of the No. 4 linear module C, and a fourth cylinder gripper mounted on the No. 4 lifting frame.

[0014] Furthermore, the cooling mechanism includes a No. 5 base mounted on the frame, a No. 5 cylinder mounted vertically on the No. 5 base, and a blower shroud mounted at the output end of the No. 5 cylinder.

[0015] Furthermore, a cooling furnace is also provided on one side of the frame, and the unloading mechanism is used to transfer the assembly from the fixture to the cooling furnace.

[0016] Furthermore, the distance between adjacent heating components and adjacent fixtures is equal.

[0017] The magnetic tile assembly heating method, using the aforementioned magnetic tile assembly heating device, includes the following steps: S1, shell loading: The shell to be heated is assembled with the magnetic tiles in the fixture using a shell loading mechanism to form an assembly; S2, indexing and rotation step: The indexer drives the turntable to rotate one station, sending the fixture containing the magnetic tile assembly to the station where the first heating component is located; S3, tiered heating step: Cylinder No. 1 drives Frame No. 1 to descend, causing all spiral heating rings to simultaneously cover the magnetic tile assembly in the fixture at the corresponding station. Each spiral heating ring is energized and heated. After maintaining a preset heating time, Cylinder No. 1 returns to its original position. The measuring device drives the turntable to rotate one station again, so that the same magnetic tile assembly enters the next heating component station in sequence. The above-mentioned descent, heating and reset actions are repeated until the magnetic tile assembly passes through all heating components in sequence and completes the stepped heating; S4, the magnetic tile assembly that has completed stepped heating rotates with the turntable to the unloading station, and the unloading mechanism takes it out of the fixture, so that the fixture becomes unloaded; S5, the unloaded fixture continues to rotate with the turntable to the cooling mechanism station, and the cooling mechanism cools the unloaded fixture to reduce the residual heat accumulated in the fixture due to receiving the heated assembly, so as to facilitate subsequent loading.

[0018] Beneficial effects of the invention: 1. This application uses a rotary table driven by an indexer to rotate in a stepwise manner, and multiple heating components are arranged at equal intervals around the periphery, so that the same magnetic tile assembly passes through all the heating components in sequence to receive gradient heating, which avoids the problem of uneven heating of the assembly in the traditional batch heating method and significantly improves the heating uniformity and the consistency of the assembly.

[0019] 2. The spiral heating ring of this application adopts a hollow tube structure and is externally connected to circulating cooling water, which can effectively remove the heat generated by the coil itself, prevent overheating damage, and extend the service life of the heating ring. The water circuit and the circuit are physically isolated, and the low-voltage, high-current operating mode and the insulated pipeline improve safety.

[0020] 3. The cooling mechanism is specifically designed for forced air cooling of the unloaded fixture after material unloading. This effectively reduces the residual heat accumulated in the fixture due to receiving high-temperature assemblies, preventing the residual heat from affecting the preheating of the next batch of unheated assemblies. This ensures that the starting temperature of each batch of assemblies is the same, improving the stability and repeatability of the process.

[0021] 4. This application integrates a shell feeding mechanism, a tiered heating mechanism, a flipping and picking component, a transfer component, and an independent cooling furnace, realizing fully automated operation from shell and magnetic tile assembly, tiered heating, assembly removal, posture adjustment, and transfer to the cooling furnace, which greatly improves production efficiency, reduces manual intervention, and is suitable for mass production scenarios.

Assembly. Detailed Implementation

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, the first embodiment provided in this application is a magnetic tile assembly heating device, including a frame 1, an indexer mounted on the frame 1, a turntable 3 fixedly mounted on the output end of the indexer, a worktable 4 fixedly mounted on the outer shell of the indexer and located above the turntable 3, and several jigs 5 circumferentially mounted on the turntable 3. It also includes a shell loading mechanism 6 mounted on the frame 1, a heating mechanism 7 mounted on the worktable 4, a unloading mechanism 8 mounted on the frame 1, and a cooling mechanism 9 mounted on the frame 1. Figure 3 , Figure 4 As shown, the heating mechanism 7 includes a first seat 71 mounted on the workbench 4, a first guide rail 72 vertically mounted on the first seat 71, a first frame 73 slidably mounted on the first guide rail 72, a first cylinder 74 mounted on the first seat 71 for driving the first frame 73 to rise and fall, and several heating components 75 circumferentially mounted on the first frame 73. The heating component 75 includes a mounting plate 751 mounted on the first frame 73 and a spiral heating ring 752 mounted on the mounting plate 751. The spiral heating ring 752 is a hollow tube, and a water connector 753 is connected to each end of the spiral heating ring 752.

[0033] It should be noted that the spiral heating ring 752 is made of hollow copper tubing. During operation, the spiral heating ring 752 is connected to a high-frequency power supply, and circulating cooling water flows through it. The copper tubing wall serves as a physical barrier between the conductive circuit and the cooling water channel. The circulating cooling water is only used to remove the resistance heat generated by the coil itself and absorb radiant heat from the workpiece to prevent the coil from overheating. Because induction heating uses a low-voltage, high-current operating mode, and the inlet and outlet water circuits use long-distance insulated pipes, the electrical safety of the water system can be effectively ensured, avoiding the risk of leakage.

[0034] In actual use, the indexing device drives the turntable 3 and its fixture 5 to rotate intermittently. The shell loading mechanism 6 feeds the magnetic tiles in the fixture 5 to be heated into an assembly 100. When the fixture 5 containing the assembly 100 rotates with the turntable 3 to below the heating mechanism 7, the first cylinder 74 drives the first frame 73 to descend along the first guide rail 72, causing several spiral heating rings 752 arranged circumferentially on the first frame 73 to descend simultaneously, covering the assembly 100 at the corresponding position. It should be noted that the heating components 75 do not heat the same assembly 100 simultaneously. Instead, as the indexing device rotates stepwise, the same assembly 100 will pass under multiple heating components 75 in sequence: the assembly 100 first enters the station of the first heating component 75 to receive initial heating, then the indexing device rotates one station, and the assembly 100 enters the station of the second heating component 75 to receive secondary heating, and so on, until the assembly 100 passes under all heating components 75 in sequence to complete the stepped heating. Each spiral heating ring 752 generates heat when energized, heating the assembly 100 it currently covers. The spiral heating ring 752 has a hollow tube structure with external water connectors 753 at both ends for circulating cooling water to cool the ring body and prevent overheating damage. After heating is complete, cylinder 74 resets, and the assembly 100, having completed all stages of heating, continues to rotate with the turntable 3 to the next workstation, where it is finally removed by the unloading mechanism 8 and cooled by the cooling mechanism 9.

[0035] In the above design, by setting up a heating mechanism 7 that is linked to the indexer and using a hollow spiral heating ring 752 with an external water cooling system, automated continuous heating operation is achieved, which effectively protects the heating ring body while significantly improving production efficiency and equipment reliability.

[0036] Specifically: such as Figure 1 , Figure 2 and Figure 3 As shown, there are three heating components 75, and the heating temperature gradient of the three heating components 75 is set.

[0037] In actual use, the three heating components 75 are set with different heating temperatures to form a gradient heating. As the assembly 100 passes through the three heating components 75 sequentially with the turntable 3, the temperature is gradually increased: the first group is heated to the intermediate temperature, the second group is heated to near the target temperature, and the third group is precisely heated or kept warm, so that the overall temperature of the assembly 100 rises uniformly to the final process requirement value.

[0038] In the above design, gradient heating can avoid thermal stress or local overheating of the assembly 100 due to excessively rapid heating, reduce the risk of damage to the magnetic tile assembly 100 during the heating process, and at the same time, staged heating helps to achieve more precise temperature control, improve heating uniformity and the consistency of the assembly 100.

[0039] Specifically: such as Figure 3 As shown, the heating mechanism 7 also includes a number of infrared sensors 76 mounted on the first frame 73, with each infrared sensor 76 corresponding to one of the heating components 75.

[0040] During the actual heating process, the infrared sensor 76 monitors the temperature on the surface of the assembly 100 or near the spiral heating ring 752 in real time and feeds the temperature signal back to the control system. When the temperature reaches the set value, the control system can adjust the heating power, start or stop heating, ensuring that the heating process always takes place within the temperature window required by the process.

[0041] In the above design, the infrared sensor 76 enables closed-loop temperature control of the heating process, which can monitor the temperature of the assembly 100 in real time and prevent overheating from causing performance degradation of the magnetic tile or damage to the assembly 100. It is especially suitable for precise heating of the magnetic tile assembly 100, which is sensitive to the heating process.

[0042] Specifically: such as Figure 5 As shown, the shell feeding mechanism 6 includes a second seat 61 mounted on the frame 1, a second linear module A62 horizontally mounted on the second seat 61, a second sliding frame 63 fixedly mounted on the output end of the second linear module A62, a second cylinder 64 horizontally mounted on the second sliding frame 63 and parallel to the second linear module A62, a second linear module B65 vertically fixedly mounted on the output end of the second cylinder 64, a second connecting frame 66 mounted on the output end of the second linear module B65, a second rotary cylinder 67 mounted on the second connecting frame 66, and a second cylinder gripper 68 mounted on the output end of the second rotary cylinder 67.

[0043] In actual use, linear module A62 drives sliding frame 63 to move horizontally to the material picking position; cylinder 64 extends horizontally to further adjust its position, so that the second cylinder gripper 68 is above the housing. Then, linear module B65 drives connecting frame 66 to descend, so that the second cylinder gripper 68 is close to the material to be picked up, and then the housing is clamped by the second cylinder gripper 68. Then, linear module B65 drives connecting frame 66 to rise, and then rotary cylinder 67 adjusts the second cylinder gripper 68 to rotate the housing to the assembly posture. Then, linear module B65 drives connecting frame 66 to move down, so that connecting frame 66 drives rotary cylinder 67 and second cylinder gripper 68 to place the clamped housing into fixture 5 for assembly with the magnetic tile in fixture 5.

[0044] In the above design, the structure and specific implementation of the shell feeding mechanism 6 can adapt to different feeding positions and material postures through the multi-degree-of-freedom combination motion of linear modules, cylinders and rotary cylinders, which improves the flexibility of feeding. At the same time, the coordinated drive of linear modules and cylinders takes into account both positioning accuracy and cost control.

[0045] Specifically: such as Figure 2 As shown, the feeding mechanism 8 includes a flipping and picking assembly 81 and a transfer assembly 82 mounted on the frame 1, as follows: Figure 7 As shown, the flipping and picking assembly 81 includes a No. 3 seat 811 mounted on the frame 1, a No. 3 guide rail A812 horizontally mounted on the No. 3 seat 811, a No. 3 slide block A813 slidably mounted on the No. 3 guide rail, a No. 3 cylinder A814 mounted on the No. 3 seat 811 for driving the No. 3 slide block A813 to slide along the No. 3 guide rail A812, a No. 3 guide rail B815 vertically mounted on the No. 3 slide block A816 slidably mounted on the No. 3 guide rail B815, a No. 3 cylinder B817 mounted on the No. 3 slide block A813 for driving the No. 3 slide block B816 to rise and fall along the No. 3 guide rail B815, a No. 3 rotary cylinder 818 mounted on the No. 3 slide block B816, and a third cylinder gripper 819 mounted at the output end of the No. 3 rotary cylinder 818.

[0046] In actual use, the flipping and picking assembly 81 removes the heated assembly 100 from the fixture 5, then flips the assembly 100 180°, and then transfers the flipped assembly 100 from the flipping and picking assembly 81 via the transfer assembly 82. The operation of the flipping and picking assembly 81 is as follows: the third cylinder A814 drives the third slide A813 to slide horizontally along the third guide rail A812 to one side of the fixture 5; the third cylinder B817 drives the third slide B816 to descend along the third guide rail B815 so that the third cylinder gripper 819 reaches the gripping position; after the third cylinder gripper 819 grips the finished product in the fixture 5, the third cylinder B817 rises, the third cylinder A814 resets, and the assembly 100 is removed from the fixture 5. Then, the third rotary cylinder 818 drives the third cylinder gripper 819 to flip the assembly 100, ready to be transferred to the transfer assembly 82.

[0047] In the above design, the structural design and specific implementation of the unloading mechanism 8, through the coordination of horizontal sliding and lifting actions and the angle adjustment of the rotary cylinder, realizes the accurate removal and posture adjustment of the assembly 100 from the fixture 5. The structure is simple and reliable, with low maintenance cost, and facilitates the subsequent connection of the transplanting component 82.

[0048] Specifically: such as Figure 6 As shown, the transplanting assembly 82 includes a fourth seat 821 mounted on the frame 1, a fourth guide rail A822 horizontally mounted on the fourth seat 821, a fourth slide block 823 slidably mounted on the fourth guide rail A822, a fourth linear module A824 mounted on the fourth seat 821 for driving the fourth slide block 823 to slide along the fourth guide rail A822, a fourth linear module B825 horizontally mounted on the fourth slide block 823 and perpendicular to the fourth guide rail A822, a fourth linear module C826 vertically mounted at the output end of the fourth linear module B825, a fourth lifting frame 827 mounted at the output end of the fourth linear module C826, and a fourth cylinder gripper 828 mounted on the fourth lifting frame 827.

[0049] In actual use, linear module A824 drives slide 823 to move horizontally along guide rail A822 to the material picking position; linear module B825 drives linear module C826 to move laterally; linear module C826 drives lifting frame 827 to lift; after the fourth cylinder gripper 828 picks up the assembly 100 from the flipping material picking component 81, linear module C826 resets, and linear modules A824, B825 and C826 work together in a three-axis manner to move assembly 100 to the predetermined unloading position.

[0050] In the above design, the three-axis linear module combination realizes full-stroke motion in the XYZ directions, which can complete precise and flexible transfer trajectories, with high positioning accuracy and stable operation, and can adapt to the complex material handling needs between different workstations.

[0051] Specifically: such as Figure 8 As shown, the cooling mechanism 9 includes a No. 5 seat 91 mounted on the frame 1, a No. 5 cylinder 92 mounted vertically on the No. 5 seat 91, and a blower shroud 93 mounted on the output end of the No. 5 cylinder 92.

[0052] In actual use, after the heated assembly 100 in fixture 5 is removed by the unloading mechanism 8, fixture 5 needs to receive the assembly 100 again. Before receiving the assembly 100, fixture 5 needs to be cooled down. When fixture 5 rotates with turntable 3 to the corresponding position of cooling mechanism 9, fixture 5 is located below air blower hood 93. Then, cylinder 92 drives air blower hood 93 to move down, and then cold air is blown into air blower hood 93 through external air source, so that the cold air blows onto fixture 5 through the lower end of air blower hood 93 to cool fixture 5.

[0053] In the above design, the cooling mechanism 9 adopts a cylinder-driven lifting air-cooling shroud structure, which can be brought close to the assembly 100 for forced air cooling when cooling is needed, and automatically retracted when not cooling to avoid interfering with the actions of other workstations. The air cooling method has a simple structure and is pollution-free.

[0054] Specifically: a cooling furnace 2 is also provided on one side of the frame 1, and the unloading mechanism 8 is used to transfer the assembly 100 from the fixture 5 into the cooling furnace 2.

[0055] In actual use, the unloading mechanism 8 removes the heated assembly 100 from the fixture 5 and transfers it to the cooling furnace 2 on one side of the frame 1. Inside the cooling furnace 2, the assembly 100 can be further cooled slowly or processed according to a predetermined cooling curve to prevent cracking or performance changes of the magnetic tile due to rapid cooling.

[0056] In the above design, an independent cooling furnace 2 is set up to achieve temperature-controlled cooling or aging treatment of the assembly 100, effectively preventing the magnetic tile from cracking or deteriorating due to rapid cooling. At the same time, the initial cooling in the heating device and the deep cooling in the furnace are separated, which optimizes the process cycle and cooling effect, and improves the final product quality of the magnetic tile assembly 100.

[0057] Specifically, the distance between adjacent heating components 75 and adjacent fixtures 5 is equal.

[0058] In actual use, the circumferentially arranged fixtures 5 are evenly distributed on the turntable 3, and the heating components 75 are also evenly spaced circumferentially on the first frame 73, with the spacing between adjacent heating components 75 being equal to the spacing between adjacent fixtures 5. When the indexer drives the turntable 3 to step, after each rotation of one fixture 5 interval, each heating component 75 is precisely aligned with the fixture 5 below, achieving synchronous heating across multiple workstations.

[0059] In the above design, the equal spacing design enables multiple heating components 75 to be aligned with multiple fixtures 5 at the same time, realizing multi-station parallel heating, which greatly improves production efficiency. At the same time, it simplifies the indexer control logic, requiring only rotation at fixed steps without additional positioning compensation, and facilitates modular expansion to further increase production capacity.

[0060] The second embodiment provided in this application is a heating method for a magnetic tile assembly, using the aforementioned magnetic tile assembly heating device, including the following steps: S1, shell loading: The shell to be heated is assembled with the magnetic tiles in the fixture 5 through the shell loading mechanism 6 to form an assembly 100; S2, indexing and rotation step: The indexer drives the turntable 3 to rotate one station, sending the fixture 5 containing the magnetic tile assembly 100 to the station where the first heating component 75 is located; S3, tiered heating step: The first cylinder 74 drives the first frame 73 to descend, so that all the spiral heating rings 752 simultaneously cover the magnetic tile assembly 100 in the fixture 5 at the corresponding station, and each spiral heating ring 752 is energized and heated, maintaining a preset heating time. Cylinder 74 is reset; the indexer drives the turntable 3 to rotate one station again, so that the same magnetic tile assembly 100 enters the next heating component 75 station in sequence, repeating the above-mentioned descent, heating, and reset actions until the magnetic tile assembly 100 passes through all heating components 75 in sequence to complete the stepped heating; S4, the magnetic tile assembly 100 that has completed stepped heating rotates with the turntable 3 to the unloading station, and the unloading mechanism 8 takes it out of the fixture 5, so that the fixture 5 becomes unloaded; S5, the unloaded fixture 5 continues to rotate with the turntable 3 to the station where the cooling mechanism 9 is located, and the cooling mechanism 9 cools the unloaded fixture 5 to reduce the residual heat accumulated in the fixture 5 due to receiving the heated assembly 100, so as to facilitate subsequent loading.

[0061] In the above design, the method uses an indexer to drive the turntable 3 to rotate in steps. Combined with the circumferentially spaced arrangement of multiple heating components 75, the same magnetic tile assembly 100 is sequentially heated by all the heating components 75, achieving a phased and gradual heating of the assembly 100. This effectively avoids thermal stress damage caused by excessively rapid heating. Simultaneously, the multi-station parallel heating significantly improves production efficiency. The cooling step targets the unloaded fixture 5, effectively reducing the residual heat accumulated in the fixture 5 due to prolonged exposure to the high-temperature assembly 100. This prevents the overheating of the fixture 5 from affecting the preheating of subsequently loaded unheated assemblies 100, ensuring the consistency of the heating start conditions for each batch of assemblies 100, and further improving the stability and repeatability of the heating process.

[0062] In further detail, it should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
