[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The following is in conjunction with the appendix Figures 1-6 The present invention will be described clearly, completely and in detail.

[0022] refer to Figures 1-6 An automated drying device 100 for electrical engineering proposed in this embodiment of the invention includes a drying chamber 10, a rotating disk 11 is provided inside the drying chamber 10, and a driving unit 20 is provided outside the drying chamber 10 to drive the rotating disk 11 to rotate in a first direction; a storage part 30 for storing coil leads is provided on the rotating disk 11; a temperature and humidity detection component 40 is also provided inside the drying chamber 10, and the temperature and humidity detection component 40 is electrically connected to the driving unit 20.

[0023] When drying electrical components such as coils, the drying chamber 10 is opened, the coil to be dried is placed in the rotating disk 11, and the coil leads are placed in the storage compartment 30. The drive unit 20 is activated to drive the rotating disk 11 to dynamically dry the coil. During this process, the temperature and humidity inside the drying chamber 10 are detected by the temperature and humidity detection component 40, and the detection signal is connected to the electrical signal of the drive unit 20. The drive unit 20 then outputs corresponding kinetic energy in real time to drive the rotating disk 11 to rotate at a more flexible speed, thereby achieving intelligent drying.

[0024] According to the embodiment of the present invention, the automated drying device 100 stores the coil lead wires by providing a storage part 30 in the drying chamber 10, thereby avoiding the problems of the lead wires tangling, sticking together or contacting each other with the inner wall of the chamber, improving the drying efficiency, and reducing the degree of damage to the lead wire insulation layer or oxidation of the wire core.

[0025] According to some embodiments of the present invention, reference Figures 1-3 The storage section 30 includes a storage tube 31 fixedly connected to the edge of the rotating disk 11, and the storage tube 31 has a through hole 32 extending in a first direction.

[0026] For example, the first direction could be the e1 direction.

[0027] When storing the coil leads, the leads are inserted into the storage tube 31 after passing through the through hole 32 to achieve the function of storing and organizing the coil leads.

[0028] By providing a through hole 32 on the storage tube 31, the convenience of the coil lead wire entering the storage tube 31 is improved, thereby improving the drying effect and efficiency of the coil.

[0029] According to some embodiments of the present invention, reference Figures 1-4 The storage cylinder 31 extends from the plane of the rotating disk 11 along a second direction perpendicular to the first direction; a storage cavity 311 is formed inside the storage cylinder 31, and a first insulating layer is coated on the inner wall of the storage cavity 311; a second insulating layer is coated on the outer wall of the storage cylinder 31.

[0030] For example, the second direction could be the e2 direction.

[0031] For example, the first insulating layer and the second insulating layer can be ceramic material layers or high-temperature resistant PPS material layers.

[0032] By providing a first insulating layer on the inner wall of the storage cavity 311 and a second insulating layer on the outer wall of the storage tube 31, interference with the coil leads during the coil drying process is prevented, and accidental contact with the coil due to the energized operation of the drive unit 20 during the drying process is prevented, thus ensuring the smooth progress of the drying process.

[0033] According to some embodiments of the present invention, reference Figures 1-4 A drive shaft 12 is fixedly connected to one side of the rotating disk 11 in the second direction, and is poweredly connected to the drive unit 20 through the drive shaft 12; the drive shaft 12 moves through the drying chamber 10 in the second direction. By setting the drive shaft to pass through the drying chamber 10 in the second direction, the mechanical structure of the drying device 100 is improved, making the device more convenient to use. The drive unit 20 drives the drive shaft 12, thereby driving the rotating disk 11 to rotate, thus realizing the function of driving the coil for dynamic drying, improving the comprehensiveness of drying and increasing drying efficiency.

[0034] According to some embodiments of the present invention, reference Figures 1-4 A rotating bearing is fitted onto the drive shaft 12. The bearing on the drive shaft 12 improves the smooth connection between the drive shaft 12 and the drying chamber 10, increases the service life of the device, reduces maintenance costs, and decreases the frequency of subsequent maintenance.

[0035] According to some embodiments of the present invention, reference Figures 1-4 The rotating disk 11 includes a tray with an annular limiting groove 111, and the drive shaft 12 is fixedly connected to the tray; protective walls 13 are distributed around the perimeter of the tray.

[0036] When in use, the coil is placed in the annular limiting groove 111. The protective wall 13 can ensure the stability of the coil as it rotates with the rotating disk 11, prevent significant centrifugal motion, ensure the continuous drying process, and improve drying efficiency.

[0037] According to some embodiments of the present invention, reference Figures 1-4 The protective wall 13 has an annular cross-sectional shape in the first direction. By setting the protective wall 13 into an annular structure, it can be adapted to the outer contour shape of the coil, thereby improving the protection effect on the coil.

[0038] According to some embodiments of the present invention, reference Figures 1-4 The drying chamber 10 has an opening at one end in the second direction and is sealed by a hinged door 14; a clean air supply fan 51 structure 50 is provided on the outside of the drying chamber 10, and the clean air supply fan 51 structure 50 is connected to the inside of the drying chamber 10.

[0039] The clean air supply fan 5150 can clean the air supplied into the drying chamber 10, thereby ensuring that the coil is not damaged or corroded by impurities mixed in with the air during the drying process in the drying chamber 10, and ensuring the drying effect and functionality of the coil after drying.

[0040] According to some embodiments of the present invention, reference Figures 1-4The clean air supply fan 51 structure 50 includes a blower 51 and an air supply duct 52 connected to the air outlet on the blower 51. The other end of the air supply duct 52 is connected to the drying chamber 10 and communicates with its interior. Using the air supply duct 52 to connect to the drying chamber 10 not only improves the efficiency of air supply and facilitates air supply, but also makes it easier to control the air supply.

[0041] For example, to facilitate the control of air supply, a regulating valve can be installed on the air supply duct 52 to facilitate the start and stop of the air supply process and the flexible adjustment of the air supply volume.

[0042] According to some embodiments of the present invention, reference Figures 1-4 A filter mechanism 53 is connected in series on the air supply duct 52.

[0043] For example, filter element 53 can be an air purifier.

[0044] By setting up the filter mechanism 53, impurities can be filtered from the air supplied to the drying chamber 10, ensuring the cleanliness of the drying air supplied to and from the drying chamber 10, thereby indirectly ensuring the performance stability of the coil after drying.

[0045] According to some embodiments of the present invention, reference Figures 1-3 The drive unit 20 includes a motor 21, and the temperature and humidity detection assembly 40 includes a temperature sensor 41 and a humidity sensor 42. The temperature sensor 41 and the humidity sensor 42 are located at the top of the drying chamber 10, and they are connected to the motor 21 via a signal transmission device.

[0046] For example, the signal transmission device can be a structure for receiving monitoring signals from the temperature sensor 41 and the humidity sensor 42, and then controlling the output speed of the motor 21 after processing. For example, it can be a controller that can process the signals from the temperature sensor 41 and the humidity sensor 42 and control the speed of the motor 21.

[0047] In practical use, when the temperature and humidity in the drying chamber 10 exceed the preset temperature threshold or the preset humidity threshold, the signal transmission device sends a command to the motor 21 to increase the operating speed of the motor 21, thereby driving the rotating disk 11 to rotate at a faster speed, thereby accelerating the heat transfer rate between the drying air and the coil, and thus increasing the cooling speed. Similarly, when the humidity in the drying chamber 10 exceeds the preset humidity threshold, the speed of the motor 21 is also increased to achieve the effect of quickly reducing the humidity in the drying chamber 10.

[0048] According to some embodiments of the present invention, reference Figures 1-6The signal transmission component includes signal wires that connect the temperature sensor 41 and the humidity sensor 42 respectively, and are connected to the motor 21 via the signal wires. By setting up signal wires that are connected to the temperature sensor 41 and the humidity sensor 42 respectively, and using the signal wires to connect the motor 21 with electrical signals, the temperature and humidity signals are stably transmitted and the working status of the motor 21 is controlled in real time, thereby improving the automation level of the drying device 100.

[0049] According to some embodiments of the present invention, reference Figures 1-5 The signal conductor is covered with a shielding layer. The shielding layer improves the operational stability of the signal conductor during use and ensures that the temperature and humidity monitoring signal is not affected by other charged objects.

[0050] According to some embodiments of the present invention, reference Figures 1-4 The rotating disc 11 is located in the middle of the drying chamber 10, and the inner wall of the drying chamber 10 is provided with a water-absorbing component.

[0051] For example, absorbent components can be physical drying materials with water absorption and moisture removal functions.

[0052] By incorporating a water-absorbing component, the drying efficiency of the coil can be improved, and the humidity index inside the drying chamber 10 can be reduced. The arrangement of the rotating disk 11 in the middle of the drying chamber 10 can improve the structural stability by ensuring the force balance between the rotating disk 11 and the drying chamber 10, thereby extending the service life of the device.

[0053] According to some embodiments of the present invention, reference Figures 1-4 The absorbent component includes a honeycomb layer structure distributed on the inner wall of the drying oven 10.

[0054] According to some embodiments of the present invention, reference Figures 1-4 A central interlayer is provided between the honeycomb layer structure and the inner wall of the drying oven 10. By providing a central interlayer, the water absorption effect can be further improved, and the noise generated by the coil during the rotation drying process can be effectively absorbed.

[0055] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
