[0023] In order to further understand the content, features and effects of the present application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0024] In order to solve the above technical problems, this embodiment provides a magnetic wheel structure, such as Figure 1 As shown, it includes a first magnetic wheel 10 and a second magnetic wheel 20. The first magnetic wheel 10 is connected to a roller drive shaft 50, and the second magnetic wheel 20 is connected to a drive assembly 40. The first magnetic wheel 10 and the second magnetic wheel 20 are acted upon by magnetic force, and the drive assembly 40 drives the second magnetic wheel 20 to rotate, so that the second magnetic wheel 20 drives the first magnetic wheel 10 to rotate, and then the first magnetic wheel 10 drives the roller drive shaft 50 to rotate, so as to drive the roller in the oven to rotate. The first magnetic wheel 10 and / or the second magnetic wheel 20 are connected to an impeller assembly 30, and when the first magnetic wheel 10 and the second magnetic wheel 20 are driven to rotate, the impeller assembly 30 can be driven to rotate at the same time, and then the impeller assembly 30 forms an airflow around to achieve heat dissipation of the first magnetic wheel 10 and the second magnetic wheel 20, thereby reducing the influence of demagnetization of the magnetic wheel assembly in a high temperature environment, thereby extending the service life of the magnetic wheel and reducing the cost.

[0025] In one embodiment, the impeller assembly 30 is connected to the second magnetic wheel 20. Specifically, the drive assembly 40 is connected to the second magnetic wheel 20 via a drive shaft 41, and the impeller assembly 30 is disposed on the drive shaft 41 between the drive assembly 40 and the second magnetic wheel 20. Exemplarily, the drive assembly 40 is a motor, the drive end of the motor is connected to the drive shaft 41, and the end of the drive shaft 41 is connected to the second magnetic wheel 20, and then the impeller assembly 30 is disposed on the drive shaft 41 between the drive assembly 40 and the second magnetic wheel 20. When the drive assembly 40 drives the drive shaft 41 to rotate and drives the second magnetic wheel 20 to rotate, the drive shaft 41 synchronously drives the impeller assembly 30 to rotate, and then the impeller assembly 30 forms an airflow around the first magnetic wheel 10 and the second magnetic wheel 20 to achieve heat dissipation of the first magnetic wheel 10 and the second magnetic wheel 20. Among them, the second magnetic wheel 20 is driven to rotate by the driving component 40, and the principle of interaction between the attraction and repulsion of the magnet is utilized to make the second magnetic wheel 20 drive the first magnetic wheel 10 to rotate, and then the first magnetic wheel 10 drives the roller drive shaft 50 to rotate. The operating principle of the magnetic wheel is the existing technology and will not be repeated here.

[0026] Furthermore, in another embodiment, the impeller assembly 30 is connected to the first magnetic wheel 10, and specifically, the impeller assembly 30 is disposed between the roller drive shaft 50 and the first magnetic wheel 10. When the second magnetic wheel 20 is driven to rotate by the driving assembly 40, and then the second magnetic wheel 20 drives the first magnetic wheel 10 and the roller drive shaft 50 to rotate, the impeller assembly 30 rotates with the roller drive shaft 50, thereby forming airflow to achieve the purpose of heat dissipation.

[0027] In the above scheme, if Figure 3 As shown, the impeller assembly 30 includes a wheel body 31 and a plurality of blades 32 arranged on the periphery of the wheel body 31, and a mounting hole 33 is opened in the center of the wheel body 31. The wheel body 31 can then be inserted into the roller drive shaft 50 or the drive shaft 41 through the mounting hole 33, so as to achieve the installation of the wheel body 31. When the wheel body 31 rotates, the blades 32 on the periphery of the wheel body 31 form airflow around the first magnetic wheel 10 and the second magnetic wheel 20, so as to achieve the purpose of heat dissipation.

[0028] In actual production, the magnetic wheel is required to be used in a clean environment, and dust accumulation may occur in the production process of the prior art. Therefore, the present embodiment further includes a housing assembly 60 disposed on the periphery of the first magnetic wheel 10, the second magnetic wheel 20 and the impeller assembly 30. The housing assembly 60 plays a role in shielding and preventing dust, thereby reducing the influence of dust on the magnetic wheel assembly.

[0029] Specifically, in the above scheme, if Figure 2As shown, the housing assembly 60 includes a plurality of side panels 61 and a plurality of bottom panels 62, and the plurality of side panels 61 and the plurality of bottom panels 62 are spliced ​​together to form an accommodation space, and the first magnetic wheel 10, the second magnetic wheel 20 and the impeller assembly 30 are installed in the accommodation space. The accommodation space is formed by splicing the edges of the plurality of side panels 61 and the plurality of bottom panels 62 together, so that the first magnetic wheel 10, the second magnetic wheel 20 and the impeller assembly 30 are located in the accommodation space, which is convenient for dust to fall off.

[0030] Furthermore, a plurality of through holes 63 are provided on the bottom plate 62, so that dust in the accommodating space can fall through the through holes 63. Alternatively, through holes 63 are provided on both the side plate 61 and the bottom plate 62, so that when the impeller assembly 30 rotates, airflow can be formed in the accommodating space of the outer shell assembly 60, thereby achieving the purpose of heat dissipation.

[0031] This embodiment further includes a mounting plate 70, and the driving assembly 40 and the roller driving shaft 50 are arranged on the mounting plate 70. The roller driving shaft 50 is rotatably arranged on the mounting plate 70 through a bearing seat, and the driving assembly 40 is vertically mounted on the mounting plate 70, so that the driving shaft 41 of the driving assembly 40 is perpendicular to the roller driving shaft 50, thereby making the axes of the first magnetic wheel 10 and the second magnetic wheel 20 perpendicular.

[0032] Furthermore, the mounting plate 70 is provided with a detection component 80 on one side of the first magnetic wheel 10 or the second magnetic wheel 20. Exemplarily, the detection component 80 may be a sensor, which detects the working state of the detection component 80 through the detection component 80, and can detect the rotation speed of the magnetic wheel in real time during the working process, so as to detect whether it is abnormal and ensure stable operation. In some other embodiments, the detection component 80 may also be a temperature detection component. Exemplarily, the temperature detection component may be a temperature sensor, which is located in the accommodating space of the housing component 60. The temperature in the accommodating space of the housing component 60 is detected by the temperature sensor to ensure the normal operation of the magnetic wheel assembly. When the temperature is too high, the drive component 40 stops running, so as to achieve the purpose of protecting the magnetic wheel assembly and avoid the demagnetization of the magnetic wheel assembly due to excessive temperature.

[0033] On the other hand, this embodiment provides an oven, comprising the magnetic wheel structure and a roller 90, wherein the roller 90 is connected to the roller drive shaft 50. The magnetic wheel structure drives the roller drive shaft 50 to rotate, and then the roller drive shaft 50 drives the roller 90 to rotate, and then the roller 90 drives the substrate to move in the oven.

[0034] To summarize, in one or more embodiments of the present application, the present application connects the first magnetic wheel with a roller drive shaft, connects the second magnetic wheel with a drive assembly, and acts through magnetic force between the first magnetic wheel and the second magnetic wheel, and drives the second magnetic wheel to rotate through the drive assembly, so that the second magnetic wheel drives the first magnetic wheel to rotate, and then the first magnetic wheel drives the roller drive shaft to rotate, thereby driving the roller in the oven to rotate, and the first magnetic wheel and / or the second magnetic wheel are connected to an impeller assembly, and when the first magnetic wheel and the second magnetic wheel are driven to rotate, the impeller assembly can be driven to rotate at the same time, and then the impeller assembly forms an airflow around it to dissipate heat for the first magnetic wheel and the second magnetic wheel, thereby reducing the impact of demagnetization of the magnetic wheel assembly in a high temperature environment, thereby extending the service life of the magnetic wheel and reducing the cost.
