DETAILED DESCRIPTION

[0038] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The applicant noted that with the continuous advancement of science and technology, induction heating technology has become one of the important technologies in the field of industrial heating today. At present, induction heating technology has been widely used in the heating treatment process of various metal materials, such as welding, quenching, annealing, etc. Among them, electromagnetic induction heating devices have attracted much attention due to their high efficiency and environmental protection. Such devices usually use the principle of electromagnetic induction to generate heat inside the heated object through eddy currents, thereby achieving a fast and uniform heating effect. In recent years, with the development of power semiconductor devices, induction heating power supplies have also achieved large capacity and high frequency, further promoting the application of induction heating technology. Secondly, in practical applications, existing electromagnetic induction heating devices usually control the heating temperature and speed by adjusting the output power of the power supply. For example, in the welding process of thick-walled pressure vessels, in order to ensure the welding quality, the welding groove needs to be preheated. At this time, an electromagnetic induction heating device can be used for rapid and uniform preheating, while maintaining a certain temperature during the welding process. In addition, in the production process of lithium-ion power batteries, the battery cells also need to be baked to remove water vapor. The traditional baking method is time-consuming and energy-intensive, while the use of electromagnetic induction heating devices can significantly improve the baking efficiency and reduce energy consumption.

[0040] However, the existing technology also has the following pain points: on the one hand, although traditional heating methods such as flames and electric heaters are widely used, they have many disadvantages, such as uneven heating, slow heating speed, and low energy utilization, which not only affect product quality, but also increase energy consumption and costs. On the other hand, although electromagnetic induction heating devices have obvious advantages in heating efficiency and uniformity, and have gradually become a new choice for industrial heating, existing electromagnetic induction heating devices also face some challenges, such as certain limitations on the materials and shapes of the heating parts, relatively high equipment costs, and increased investment pressure on enterprises. The existing adjustment method may cause power grid pollution problems, which is not in line with the development concept of green environmental protection and needs further optimization and improvement. Therefore, it is particularly important to develop a heating system and its control method to meet the purpose of low energy consumption and adjustability.

[0041] As mentioned in the background technology, the problem that the current electromagnetic induction heating system needs to solve is that it is difficult to flexibly adjust the heating temperature and speed according to actual needs to improve the heating efficiency and heating uniformity; the electromagnetic induction heating system has certain limitations on the material and shape of the heated parts, and the equipment cost is relatively high; in addition, the existing adjustment method may cause problems such as power grid pollution, and further optimization and improvement are needed.

[0042] To solve the above problems, refer to Figure 1~Figure 5 The present invention provides a heating system, including an execution unit 100 and a control unit 200. The execution unit 100 includes a lower pressing member 110 and a heating device 120 which are arranged at intervals. The control unit 200 is electrically connected to the execution unit 100, and is used to control the lower pressing member 110 to press down the heated member 1 to the heating position, and is used to control the heating device 120 to rotate at the heating position to heat the heated member 1; wherein, in the heating system of the present invention, the heating device 120 is a permanent magnetic device.

[0043] In the heating system of the present invention, the execution unit 100 is electrically connected to the control unit 200; the execution unit 100 includes a lower pressing member 110 and a heating device 120, i.e., a permanent magnetic device; the control unit 200 is electrically connected to the lower pressing member 110 and the heating device 120, i.e., a permanent magnetic device; the control unit 200 is used to control the lower pressing member 110 to press and move the heated member 1 toward one side of the heating device 120, i.e., the permanent magnetic device; and the control unit 200 is used to control the heating device 120, i.e., the permanent magnetic device, to perform a heating operation on the heated member 1 at the heating position. Thus, the lower pressing member 110 presses the heated member 1 to the heating position, and the heating device 120, i.e., the permanent magnetic device, heats the heated member 1, the lower pressing member 110 can ensure that the heated member 1 remains fixed at the heating position, and the heating device 120, i.e., the permanent magnetic device, rotates at the heating position, specifically at the heated member 1, to heat the heated member 1, which can avoid uneven heating caused by the movement of the heated member 1, and the heating uniformity and stability of the heated member 1 are improved, thereby significantly improving the product quality. The heating device 120, i.e., the permanent magnet device, rotates relative to the heated member 1 at the heating position to heat the heated member 1, which improves the heating efficiency and avoids energy waste. Therefore, the heating system can solve the problem that the existing system is difficult to adjust the heating temperature and speed according to actual needs.

[0044] In some embodiments, the heating device 120 specifically adopts a disc-type permanent magnetic device or a pagoda-type permanent magnetic device. The control unit 200 is used to control the rotation speed, rotation direction and rotation power change of the heating device 120, i.e., the permanent magnetic device. In view of different heating requirements caused by the shape, material and other limiting factors of the heated part 1, the rotation parameters of the heating device 120, i.e., the permanent magnetic device, relative to the heating position are changed, so that the heating device 120, i.e., the permanent magnetic device, can meet the different heating requirements of the heated part 1 when heating the heated part 1.

[0045] In some embodiments, the control unit 200 includes a first sensor 210. The first sensor 210 is a position sensor, which is used to monitor the position changes of the heated member 1 and the execution unit 100 in real time, so as to provide an accurate position feedback signal to the control unit 200. The first sensor 210 is used to obtain the position of the heated member 1 in real time; the control unit 200 is also used to set and obtain a preset value of the heating position of the heated member 1, and to control the pressing member 110 to press the heated member 1 to the heating position according to the set preset value of the heating position and the position of the heated member 1 detected by the first sensor 210.

[0046] In some embodiments, the control unit 200 further includes a second sensor 220. The second sensor 220 is a temperature sensor, which is used to monitor the temperature change of the heated part 1 during the heating process in real time, thereby providing an accurate temperature feedback signal to the control unit 200. The second sensor 220 is used to obtain the temperature of the heated part 1 in real time; the control unit 200 is used to control the heating device 120, i.e., the permanent magnet device, to rotate around the vertical direction Y according to the temperature of the heated part 1 obtained by the second sensor 220, and specifically controls the heating device 120, i.e., the permanent magnet device, to rotate around the vertical direction Y at the heating position to heat the heated part 1, wherein the vertical direction Y is the direction in which the heating device 120, i.e., the permanent magnet device, points to the lower pressing part 110.

[0047] In an embodiment of the present application, the control unit 200 is a high-performance PLC or microcontroller, which is responsible for receiving and processing various sensor signals. For example, the control unit 200 is used to receive position feedback information of the first sensor 210, and the control unit 200 is also used to receive temperature feedback information of the second sensor 220.

[0048] It should be noted that when the part 1 to be heated is a wheel hub, and the control unit 200 is a controller, the real-time position of the wheel hub is detected by a position sensor, and the controller adjusts the action of the pressing member 110 according to the preset value of the heating position of the wheel hub, to ensure that the wheel hub is accurately pressed down to the heating position for heating. Among them, the heating position is a reasonable position where the wheel hub can be heated, the preset value of the heating position includes multiple positions, and the heating position is one of the preset values ​​of the heating position. The part 1 to be heated, such as the wheel hub, is accurately pressed down to the heating position by the pressing member 110, and remains stationary during the heating process of the part 1 to be heated. This design ensures the uniformity and stability of the heating of the part 1 to be heated. The part 1 to be heated is heated at a fixed position, which avoids uneven heating due to position movement, and the heating uniformity and stability of the part 1 to be heated are improved, thereby significantly improving the product quality.

[0049] It should be noted that when the heated part 1 is a wheel hub, the control unit 200 is a controller, and the heating device 120 is a permanent magnet device, the real-time temperature of the heated part 1, i.e., the wheel hub, is detected by the second sensor 220, i.e., the temperature sensor. The controller controls the rotation speed and rotation direction of the heating device 120, i.e., the permanent magnet device, according to the temperature feedback signal of the second sensor 220, i.e., the temperature sensor. When the heated part 1, i.e., the wheel hub, reaches the target heating temperature, the heating device 120, i.e., the permanent magnet device, stops rotating to save energy and avoid overheating. The control unit 200 adopts a PID control algorithm to adjust the rotation speed and heating power of the heating device 120, i.e., the permanent magnet device, in real time according to the temperature feedback signal of the second sensor 220, i.e., the temperature sensor, to achieve precise temperature control. The heated part 1 is heated by rotating the heating device 120, i.e., the permanent magnet device, and the heated part 1 stops rotating immediately when the heated part 1 reaches the target heating temperature. This on-demand heating method not only improves the heating efficiency, but also effectively avoids energy waste. Compared with the traditional continuous heating method, the present invention can quickly stop heating after reaching the required temperature, thereby achieving significant energy saving effects.

[0050] It should be noted that, in some embodiments, Figure 3~Figure 5 The execution unit 100 also includes a rotation connection assembly 150 and a rotation drive assembly (unnumbered); the rotation connection assembly 150 is capable of rotating around the vertical direction Y, and the rotation connection assembly 150 is configured to be mechanically and detachably connected to the heating device 120, i.e., the permanent magnet device, and is configured to drive the heating device 120, i.e., the permanent magnet device, to rotate; the rotation drive assembly is configured to drive the rotation connection assembly 150 to rotate around the vertical direction Y.

[0051] In some embodiments, the rotary coupling assembly 150 includes a rotary body 151. The rotary body 151 includes a turntable 152, which is disposed on one side of the rotary body 151 close to the heating device 120, ie, the permanent magnet device, and is used to carry the heating device 120, ie, the permanent magnet device.

[0052] In some embodiments, the rotating body 151 further includes a coupling, and the turntable 152 is connected to the rotating drive assembly through the coupling; the turntable 152 and the rotating drive assembly can also be connected through a gear assembly to achieve power mechanical transmission. In some other embodiments, alternatively, the rotating body 151 further includes a rotating shaft and a clutch, and the rotating shaft is driven by the rotating drive assembly to rotate at a high speed through the clutch, and the rotating shaft drives the heating device 120, i.e., the permanent magnet device, to rotate together.

[0053] In some embodiments, the heating device 120 includes a permanent magnet assembly. The permanent magnet assembly includes an N-pole permanent magnet and an S-pole permanent magnet. A plurality of N-pole permanent magnets and a plurality of S-pole permanent magnets are distributed in a ring shape on the rotating body 151, and the N-pole permanent magnets and the S-pole permanent magnets are arranged alternately and spaced apart. The heated part 1 is placed on the surface of the permanent magnet assembly. Specifically, the N-pole permanent magnet and the S-pole permanent magnet of the permanent magnet assembly are arranged in strips on the top surface of the turntable 152, and the two are arranged together on the top surface of the turntable 152 in a radiating or radial shape. The heating device 120, i.e., the permanent magnet device, is provided with a plurality of permanent magnets or permanent magnet blocks to form a large permanent magnet. The number of permanent magnets can be an even number such as 2, 4, 6, 8, 10, 12, etc., and the polar directions of the adjacent permanent magnet poles are opposite, i.e., N-pole permanent magnets and S-pole permanent magnets, respectively.

[0054] When heating the heated part 1, the heated part 1 is placed on the upper surface of the turntable 152, and the rotating drive assembly is started to drive the rotating body 151. The permanent magnet assembly on the rotating body 151 rotates with the rotating body 151, and the N-pole permanent magnet and the S-pole permanent magnet generate an alternating magnetic field on the surface of the heated part 1. The surface of the heated part 1 generates heat and heats up under the action of the alternating magnetic field, so that the heated part 1, i.e., the bottom surface of the hub, can be evenly heated.

[0055] In some embodiments, when heating the heated member 1, the rotational speed frequency of the rotating connection member 150 and the rotating body 151 is changed by adjusting the operating frequency of the rotating drive assembly to control the rate of cutting the magnetic flux lines, thereby more accurately adjusting the heating temperature of the heated member 1. In addition, before heating the heated member 1, the number of N-pole permanent magnets and S-pole permanent magnets can be changed according to the heating requirements.

[0056] Alternatively, in some other embodiments, the heating device 120, i.e., the permanent magnetic device, includes a permanent magnetic chuck; the heated part 1 is placed on the surface of the permanent magnetic chuck. An independent magnetic pole assembly or an even-numbered combination of magnetic pole assemblies are symmetrically arranged on the outer edge of the disk surface of the permanent magnetic chuck, and the independent magnetic pole assembly or the even-numbered combination of magnetic pole assemblies includes a fixed magnet and a movable magnet as at least one magnetic source and can rotate around the vertical direction Y to generate a changing magnetic field passing through the heated part 1, and the magnetic source is a permanent magnet; and one or more of the permanent magnets have a suitable magnetic flux distribution to facilitate causing a suitable temperature distribution in the heated part 1. By designing the heating device 120, i.e., the permanent magnet device, as a magnet rotating heating, precise heating control can be achieved. The above can also be replaced by other embodiments, and the factors such as the magnetic pole orientation, number, size, speed, strength, vertical gap between vertically offset rotors in a single rotor group, longitudinal gap between adjacent rotor groups, lateral offset placement of rotors in a single rotor group, vertical distance between the rotor and the heated member 1, number of rotor groups, relative speed of the heated member 1, and thickness of the heated member 1 can be changed. In some embodiments, the thickness of the magnet can meet any of: 15mm~100mm, 15mm~40mm, 20mm~40mm, 25mm~35mm.

[0057] It should be noted that when the heating temperature of the heated part 1 increases, the use of permanent magnets can require less energy to apply the required heat energy. When the temperature increases too much, the electromagnet is not adapted to the normal operating temperature, and a lot of resources are spent to fully cool the electromagnet. In contrast, permanent magnets can operate at higher temperatures, do not generate heat themselves, and may require less cooling.

[0058] In addition, in some embodiments, a metal bar assembly may be added near the permanent magnet to improve the condition. The metal bar assembly includes at least one of a movable metal bar or a fixed metal bar or a combination of the two. The metal bar assembly may generate a variable magnetic field relative to the permanent magnet. The metal bar assembly may be one or more of a movable metal bar, a fixed metal bar, a plate, and a board. By changing the relative distance between any metal bar in the metal bar assembly and the permanent magnet, the heating device 120, i.e., the permanent magnet device, may better generate the required variable magnetic field.

[0059] In some embodiments, the control unit 200 is further configured to control the pressing member 110 to release the heated member 1 after the heated member 1 has been completely heated.

[0060] In some embodiments, the control unit 200 is further configured to control the heating device 120 , ie, the permanent magnet device, to stop rotating after the heated component 1 is heated to a target heating temperature.

[0061] In the heating system of the present invention, the control unit 200 is used to obtain the temperature of the heated part 1, such as the wheel hub, in real time by controlling the heating device 120, i.e., the permanent magnet device, to rotate around the vertical direction Y according to the temperature feedback signal obtained by the second sensor 220. The control unit 200 uses a PID control algorithm to automatically adjust the rotation speed, rotation direction, and heating power of the heating device 120, i.e., the permanent magnet device, in real time according to the temperature feedback signal of the second sensor 220, i.e., the temperature sensor, so as to achieve accurate temperature control of the heated part 1. When the temperature of the heated part 1 reaches the target heating temperature, the control unit 200 immediately stops the rotation of the heating device 120, i.e., the permanent magnet device, so as to save energy and avoid overheating.

[0062] In some embodiments, the rotation drive assembly of the execution unit 100 includes a first drive member 130. The first drive member 130 is a motor. The first drive member 130 is electrically connected to the heating device 120, i.e., the permanent magnet device, and the control unit 200, respectively. The control unit 200 is used to control the speed and torque of the first drive member 130, i.e., the motor, according to the heating requirements of the heated member 1, so as to control the first drive member 130 to drive the heating device 120, i.e., the permanent magnet device, to move toward or away from the lower pressing member 110.

[0063] In some embodiments, the rotation drive assembly of the execution unit 100 further includes a second drive member 140. The second drive member 140 is a motor. The second drive member 140 is electrically connected to the heating device 120, i.e., the permanent magnet device, and the control unit 200, respectively. The control unit 200 is used to control the speed and torque change of the second drive member 140, i.e., the motor, according to the state of the heating device 120, i.e., the permanent magnet device, so as to control the second drive member 140 to drive the heating device 120, i.e., the permanent magnet device, to rotate at the heating position, and specifically, the permanent magnet device can be rotated around the vertical direction Y at the heating position.

[0064] In a specific embodiment, since both the first driving member 130 and the second driving member 140 are motors, the heating system of the present invention accurately controls the speed and torque of the first driving member 130 and / or the second driving member 140 according to the heating demand of the heated member 1 and the state of the heating device 120, i.e., the permanent magnet device. During the heating process of the heated member 1, the control unit 200 can obtain the operating state of the first driving member 130 and / or the second driving member 140 in real time, and the operating state mainly includes the speed and torque of each motor, so as to ensure that the first driving member 130 and / or the second driving member 140 can work stably and efficiently. Since both the first driving member 130 and the second driving member 140 are motors, the motors are accurately controlled by the control unit 200, which makes the heating process of the heated member 1 highly accurate and controllable. In addition, the motor is accurately controlled by the controller, and the speed and torque of the motor are adjusted according to the heating demand of the wheel hub and the state of the permanent magnet device to ensure the stability and efficiency of the heating process.

[0065] In some embodiments, the execution unit 100 also includes a release aid. The release aid may include a shock absorber. The shock absorber is arranged on the side surface of the heating device 120, i.e., the permanent magnetic device, facing the lower pressure piece 110 and the part to be heated 1. The shock absorber may be an elastic member such as an elastic sheet or a spring. When the lower pressure piece 110 stretches the part to be heated 1 upward, it can offset the permanent magnetic force generated by the heating device 120, i.e., the permanent magnetic device, and the gravity of the part to be heated 1. The shock absorber is used to make it easy for the part to be heated 1 to be separated from the heating device 120, i.e., the permanent magnetic device. At the same time, it can reduce the vibration friction between the part to be heated 1 and the heating device 120, i.e., the permanent magnetic device, to prevent damage to the outer surface quality of the part to be heated 1.

[0066] In some embodiments, the lower pressure piece 110 is arranged opposite to the heating device 120, i.e., the permanent magnet device. The lower pressure piece 110 is extended along the vertical direction Y and is arranged on the upper side of the heating device 120, i.e., the permanent magnet device. The lower pressure piece 110 is equivalent to a longitudinal telescopic piece. The lower pressure piece 110 is connected to the control unit 200. The control unit 200 is used to control the telescopic movement of the lower pressure piece 110 along the vertical direction Y to grab and move the heated part 1, i.e., the wheel hub; the lower pressure piece 110 can be a structural component of a connected hydraulic cylinder and a connecting sleeve, and the hydraulic cylinder is used to drive the telescopic movement of the connecting sleeve.

[0067] In addition, an adsorption member can be provided at one end of the lower pressing member 110 close to the heating device 120, i.e., the permanent magnetic device, to facilitate the material suction or discharge operation. Since the heated member 1 is a wheel hub, its weight is relatively large, and the adsorption member can generate a relatively large adsorption force, such as an electromagnetic adsorption force, to firmly grasp the heated member 1.

[0068] At the same time, when the part 1 to be heated is a wheel hub, since the central area of ​​the wheel hub is generally designed as a hollow structure, a radial telescopic part can also be provided at one end of the lower pressing piece 110 close to the heating device 120, i.e., the permanent magnet device. The radial telescopic part is connected to the end of the lower pressing piece 110 close to the heating device 120, i.e., the permanent magnet device. When it is necessary to move the heated wheel hub, the radial telescopic part expands along the radial direction of the wheel hub toward the side away from the hollow structure and firmly grasps the part to be heated 1 for material discharge transfer. When it is necessary to place the lower wheel hub, the radial telescopic part contracts along the radial direction of the wheel hub toward the side close to the hollow structure until it is separated from the part to be heated 1. During the clamping process, the traditional clamping jaws should be prevented from deforming or damaging the part to be heated 1.

[0069] Furthermore, the lower pressing member 110 also includes a combination of at least one or more of an electric telescopic member, a pneumatic telescopic member, and a hydraulic telescopic member to be connected to an adsorption member or a radial telescopic member. The control unit 200 is used to control the lower pressing member 110 to align along the direction of the incoming material path of the part to be heated 1 and grasp and move the part to be heated 1 to the heating position, so as to increase the flexibility, positioning accuracy and automation effect of grasping the part to be heated 1, so that the lower pressing member 110 can accurately place the part to be heated 1, such as a wheel hub, in the heating position, ensuring the accuracy of the heating process.

[0070] In addition, the lower pressing member 110 further includes a push pin 111 for pushing the heated member 1 onto the turntable 152 before heating. A groove for accommodating the heated member 1 may be provided on a side of the turntable 152 facing the heated member 1 .

[0071] In some other embodiments, the execution unit 100 further includes a pusher, which is connected to the control unit 200. The control unit 200 is used to control the pusher to push the part to be heated 1 toward the direction of the heating device 120, i.e., the permanent magnetic device. The pusher needs to be designed to be compatible with the position of the rotating body 151. The rotating body 151 can be partially hollowed out, such as to avoid through holes, so that the pusher can pass through the rotating body 151. The lower pressing member 110 generates an upward tensile force on the part to be heated 1, and the pusher generates an upward pushing force on the part to be heated 1. The two together generate a force to offset the permanent magnetic force generated by the heating device 120, i.e., the permanent magnetic device, and the gravity of the part to be heated 1, so as to separate the part to be heated 1 from the heating device 120, i.e., the permanent magnetic device, and transfer the material out. The part to be heated 1 is pushed out by the pusher without damaging the part to be heated 1. Furthermore, since the pressing member 110 clamps the side of the heated member 1 such as the wheel hub from one side and the pushing member clamps the other side of the heated member 1 such as the wheel hub from the other side, the pressing member 110 and the pushing member can be used to facilitate the separation of the heated member 1 from the heating device 120, i.e., the permanent magnet device, and can simultaneously clamp and fix the heated member 1, thereby achieving double fixation of the heated member 1.

[0072] In some embodiments, the control unit 200 is used to control the precise movement of the execution unit 100, for example, the control unit 200 is used to control the precise movement of the pressing member 110 and / or the pushing member, the rotating connection assembly 150, the heating device 120, i.e., the permanent magnetic device, the first driving member 130, and the second driving member 140. Specifically, the pressing member 110 and / or the pushing member can perform the pressing movement, stop the pressing movement, rise, and release the heating member 1 according to the instructions of the control unit 200, i.e., the controller. The heating device 120, i.e., the permanent magnetic device, can adjust any operation of the rotation angle, rotation speed, rotation power, heating power, or stop rotation according to the instructions of the control unit 200, i.e., the controller. The first driving member 130 can adjust its own rotation speed and torque according to the instructions of the control unit 200, i.e., the controller to drive the heating device 120, i.e., the permanent magnetic device, to perform precise movements toward or away from the pressing member 110, or drive the heating device 120, i.e., the permanent magnetic device, to stop moving. The second driving member 140 can adjust its own rotation speed and torque according to the instruction of the control unit 200, i.e., the controller, to drive the heating device 120, i.e., the permanent magnet device, to perform precise movements of rotating or stopping the rotation around the vertical direction Y. Therefore, the heating system of the present invention can be flexibly adjusted according to different heating requirements and material properties of the heated part 1 to achieve a personalized heating solution. This flexibility enables the heating system of the present invention to be widely adapted to various industrial heating scenarios.

[0073] In some embodiments, the control unit 200 is also used to obtain energy consumption information of the heated member 1 during the heating process to adjust the heating strategy of the heated member 1, the operating state of the first driving member 130, and the operating state of the second driving member 140. The heating system of the present invention monitors the energy consumption data of the heated member 1 during the heating process in real time, automatically adjusts the heating strategy of the heated member 1 and the operating state of the motor to reduce energy consumption, optimizes the heating process, reduces unnecessary energy waste, and achieves energy saving and environmental protection goals.

[0074] In some embodiments, the heating system of the present invention further includes a fault diagnosis unit 300, which is electrically connected to the lower pressing member 110, the heating device 120, i.e., the permanent magnetic device, the first sensor 210, the second sensor 220, the first driving member 130, and the second driving member 140. The fault diagnosis unit 300 is a built-in fault diagnosis mechanism of the heating system of the present invention, and the fault diagnosis unit 300 is used for fault diagnosis and protection, so as to monitor the working status of each key component in real time, and once an abnormality is found, protective measures are immediately taken and an alarm is issued to ensure the safe operation of the equipment.

[0075] In the heating system of the present application, the control unit 200 is electrically connected to the execution unit 100, and the execution unit 100 includes a pressing member 110 and a heating device 120, i.e., a permanent magnet device, which are arranged at intervals from each other. The control unit 200 is used to control the pressing member 110 to press the heated member 1 to the heating position, and to control the heating device 120, i.e., the permanent magnet device, to rotate at the heating position to heat the heated member 1, thereby ensuring uniform and stable heating of the heated member 1. The heated member 1 is heated by rotating the heating device 120, i.e., the permanent magnet device, relative to the heated member 1 at the heating position around the vertical Y, and the rotation is stopped after the target heating temperature of the heated member 1 is reached. Therefore, the heating system of the present invention can solve the problem that the existing system is difficult to adjust the heating temperature and speed according to actual needs, and can achieve a fast and uniform heating effect and improve the heating efficiency. In addition, the heating system of the present invention adopts a low-energy consumption design, and effectively reduces energy consumption and emissions by accurately controlling the heating process and the motor operation state. The heating system of the present invention performs a system-built-in fault diagnosis and protection mechanism by setting a fault diagnosis unit 300 to ensure that the equipment maintains stability and reliability during long-term operation. Furthermore, the heating system of the present invention can be flexibly adjusted according to the different heating requirements and material properties of the heated part 1 to realize a personalized heating solution. In summary, the permanent magnetic induction heating control system of the present invention can fully meet the higher requirements of industrial production for heating technology and realize an efficient, uniform and environmentally friendly heating process.

[0076] Based on the above heating system, the present invention also provides a control method for the heating system, comprising the steps of:

[0077] Step S100: setting a target heating temperature and a preset heating position of the heated component 1.

[0078] In this step S100, the target heating temperature of the part to be heated 1 is set, the preset value of the heating position of the part to be heated 1 is set, and the parameters such as the heating time and heating speed of the part to be heated 1 are set, and the working status of all components in the control unit 200 and the execution unit 100 is checked to ensure the normal operation of the heating system of the present invention and provide a data basis for subsequent steps.

[0079] Step S200: Obtain the position of the part to be heated 1, and adjust the pressing member 110 to press the part to be heated 1 to the heating position according to the preset value of the heating position; wherein, when heating the part to be heated 1, the pressing member 110 is pressed down on the part to be heated 1 and keeps the part to be heated 1 stationary; until the heating of the part to be heated 1 is completed, the pressing member 110 releases the part to be heated 1.

[0080] In this step S200, the position of the heated part 1, i.e., the wheel hub, is acquired in real time by the first sensor 210, i.e., the position sensor, and the action of the pressing member 110 is automatically adjusted according to the preset position value of the heated part 1, so as to ensure that the heated part 1, i.e., the wheel hub, is accurately pressed down to a suitable heating position. During the heating process, the pressing member 110 is used to keep the heated part 1 immobile to ensure the stability of the heating. After the heating of the heated part 1 is completed, the pressing member 110 is controlled to rise and release the heated part 1.

[0081] Step S300: obtaining the temperature of the heated part 1, rotating the heating device 120, i.e., the permanent magnet device, to heat the heated part 1 until the heated part 1 reaches the target heating temperature, and then stopping the heating device 120, i.e., the permanent magnet device, from rotating and heating the heated part 1.

[0082] In the control method of the above-mentioned heating system provided by the present invention, the target heating temperature and the preset value of the heating position of the part to be heated 1 are first set, and by obtaining the real-time position of the part to be heated 1 and according to the preset value of the heating position, the action of the pressing member 110 is adjusted to press the part to be heated 1 down to the heating position for heating, and the heating position is one of the positions in the preset value of the heating position and is a reasonable heating position; during the heating process of the part to be heated 1, the pressing member 110 keeps the part to be heated 1 stationary, and after the heating of the part to be heated 1 is completed, the pressing member 110 moves toward the side away from the heating device 120, i.e., the permanent magnet device, and releases the part to be heated 1; by setting the position of the part to be heated 1, the rotation speed and heating power of the heating device 120, i.e., the permanent magnet device, are adjusted until the temperature of the part to be heated 1 reaches the set target heating temperature, and the heating device 120, i.e., the permanent magnet device, stops rotating and stops heating the part to be heated 1.

[0083] Therefore, the heating system and control method of the present invention are intended to achieve comprehensive control of the entire heating system through the control unit 200, including precise control of the lower pressure member 110, the heating device 120, i.e., the permanent magnet device, the first drive member 130, and the second drive member 140. Through optimized control logic and software algorithms, the system can ensure the uniformity, stability, and efficiency of the heating process, while meeting the requirements of environmental protection and cost control. Due to the adoption of low-energy design and precise heating control method, the system can effectively reduce energy consumption and emissions. This adjustment method will not cause power grid pollution, is more friendly to the power grid, and helps to maintain the stable operation of the power system. In addition, since the heating system of the present invention achieves the effects of uniformity, stability, efficiency, and environmental protection of the heating process, these effects work together to improve the quality and efficiency of industrial production, and can significantly reduce energy consumption and maintenance costs in long-term use, which in turn overcomes the disadvantage of high equipment cost. Due to the improvement of product quality and heating efficiency, the production efficiency and market competitiveness of the enterprise will also be improved.
