Therefore, they should not be construed as limitations on this application.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] See Figure 1 This application provides an impregnation device, including a baking mechanism 10, an impregnation mechanism 20, a feeding mechanism 30, and a fixed frame 40. The baking mechanism 10 and the impregnation mechanism 20 are both connected to the fixed frame 40. The fixed frame 40 has a first station and a second station. The impregnation mechanism 20 and the fixed frame 40 are slidably connected. The impregnation mechanism 20 can be selectively slid to the first station or the second station. The feeding mechanism 30 is used to transport the material in the baking mechanism 10 to the impregnation mechanism 20 located at the second station.

[0030] In practical applications, the impregnation process for capacitor components includes baking and impregnation. The baking mechanism 10 first bakes the capacitor components, and then the feeding mechanism 30 removes the capacitor components from the baking mechanism 10 and places them into the impregnation mechanism 20 for impregnation. After impregnation is completed, the capacitor components are removed from the impregnation mechanism 20. To improve impregnation efficiency, the impregnation mechanism 20 may include multiple impregnation cylinders, which are slidably connected to the fixing frame 40. When the impregnation cylinder moves to the second station, the feeding mechanism 30 removes the capacitor components from the baking mechanism 10 and places them into the impregnation cylinder. The impregnation cylinder filled with capacitor components moves to the first station for impregnation, and the next impregnation cylinder moves to the second station to be fed by the feeding mechanism 30. This cycle continues until all impregnation cylinders are filled with capacitor components.

[0031] See Figure 2 The baking mechanism 10 includes a frame 1 and a fan. The frame 1 has an air inlet 16 and an exhaust 17. The frame 1 has a receiving cavity for accommodating multiple baking trays 4 arranged sequentially along the height direction of the frame 1. The air outlet of the fan is connected to the air inlet 16, and the air inlet of the fan is connected to the exhaust 17.

[0032] In practical applications, the baking tray 4 is used to load capacitor components. The air outlet and air inlet 16 of the fan are connected. The hot air blown out by the fan enters the receiving cavity of the frame 1 through the air inlet 16. The hot air flows in the receiving cavity and flows out of the frame 1 through the exhaust hole 17. The exhaust hole 17 is connected to the air inlet of the fan, so that the hot air returns to the fan and realizes the hot air circulation baking.

[0033] Compared to existing technologies, the baking mechanism 10 of this application uses a fan for baking. The fan forces the hot air to circulate, allowing heat to quickly penetrate to every corner of the capacitor components, reducing local temperature differences and ensuring that each layer is heated evenly when baking multiple layers at the same time. Compared to traditional static heating, the dynamic air delivery of the fan can reduce the problem of uneven heat distribution caused by material accumulation or obstruction.

[0034] See Figure 2 and Figure 3 The frame 1 includes a bottom plate 11 and a top plate 12, with a cavity formed between the top plate 12 and the bottom plate 11. The bottom plate 11 has multiple air inlets 16 on the side facing the cavity, and the top plate 12 has multiple exhaust holes 17 on the side facing the cavity.

[0035] In practical applications, hot air, with its lower density, naturally rises. The air inlet 16, located at the bottom plate 11, allows the hot air to enter the cavity and form an upward airflow, ultimately exiting through the exhaust vent 17 on the top plate 12, creating an efficient heat circulation path. This design achieves natural heat flow without requiring additional fan power, reducing energy consumption. Furthermore, the longer airflow path from the bottom plate 11 to the top plate 12 allows the hot air to fully contact the material surface, reducing baking dead zones. The air inlet 16 on the bottom plate 11 facilitates direct connection to a fan, shortening the contact distance between the heat source and the airflow, thus reducing heat loss.

[0036] See Figure 4 The baking mechanism 10 includes an air inlet pipe 2 and an exhaust pipe. The air inlet pipe 2 is connected to the frame 1 and communicates with the air inlet hole 16. The exhaust pipe is connected to the frame 1 and communicates with the exhaust hole 17. The air inlet pipe 2 is connected to the air outlet of the fan, and the exhaust pipe is connected to the air inlet of the fan.

[0037] In practical applications, since there are usually many air inlets 16 and exhaust vents 17, this application provides an air inlet pipe 2 and an exhaust pipe to facilitate the connection between the fan and the air inlets 16 and exhaust vents 17. The base plate 11 has two opposite sides, one side facing the baking tray 4 with an air inlet 16, and the other side is connected to the air inlet pipe 2. One end of the air inlet pipe 2 is connected to the air inlet 16, and the other end is connected to the fan, which can ensure that the airflow input path is minimized and avoid pressure loss caused by pipe bends or excessive length. At the same time, the top plate 12 has two opposite sides, one side facing the baking tray 4 with an exhaust vent 17, and the other side is connected to the exhaust pipe, which is connected to the fan, so that the hot air flowing out of the frame 1 is sent back into the fan for circulation, improving the hot air circulation efficiency.

[0038] In one embodiment, the baking mechanism 10 includes a heating element connected between the exhaust pipe and the air inlet of the fan, wherein the air in the exhaust pipe is heated by the heating element and then enters the fan; or, the heating element is connected between the air inlet pipe 2 and the air outlet of the fan, wherein the air in the air outlet is heated by the heating element and then enters the air inlet pipe 2.

[0039] In practical applications, to ensure that the hot air blown in by the fan through the air inlet 16 has a certain temperature, this application also includes a heating element. The fan is mainly responsible for airflow, while the heating element converts cold air into hot air, which then enters the air inlet 16 to bake the capacitor components. The heating element can be connected to the exhaust duct to heat the cold air entering the fan, enabling dynamic temperature regulation of the circulated air, which is particularly suitable for scenarios requiring constant temperature.

[0040] The heating element can also be connected to the air inlet pipe 2 to heat the cold air blown into the air inlet hole 16 by the fan, shorten the heating time, and prevent the high-temperature airflow from directly contacting the fan motor, thereby reducing the heat load on the core components.

[0041] See again Figure 3 The baking mechanism 10 includes a baking tray 4 and a power unit 5. Multiple baking trays 4 are arranged sequentially along the height direction of the frame 1. The power unit 5 is used to drive the multiple baking trays 4 to move within the frame 1.

[0042] In practical applications, the movable baking tray 4 can actively change the relative position of the material and the heat source, reducing localized overheating or underheating caused by a fixed position. The main function of the moving baking tray 4 within the frame 1 is to achieve uniform heating through dynamic adjustment. The power component 5 can be a motor or a cylinder.

[0043] See again Figure 2 The frame 1 has a left chamber 13 and a right chamber 14 inside. Along the height direction of the frame 1, multiple baking trays 4 are arranged in the left chamber 13 and the right chamber 14 respectively. There is one fan, which is connected to both the left chamber 13 and the right chamber 14. There are multiple fans, with at least one fan connected to the left chamber 13 and at least one fan connected to the right chamber 14.

[0044] In practical applications, in order to realize the function of batch baking in one go by the baking mechanism 10, the frame 1 has a left chamber 13 and a right chamber 14. Multiple baking trays 4 are arranged in the left chamber 13 along the height direction of the frame 1, and multiple baking trays 4 are arranged in the right chamber 14 along the height direction of the frame 1. Each baking tray 4 can circulate between the left chamber 13 and the right chamber 14. A fan can be set up, and a fan can be connected to the center position between the left chamber 13 and the right chamber 14 to ensure that the flow path of the fan blowing into the two chambers is the same and to ensure that the temperature of the two chambers is consistent.

[0045] Multiple fans can also be used, with at least one fan connected to the left chamber 13 and at least one fan connected to the right chamber 14, to improve baking efficiency and hot air circulation efficiency.

[0046] See again Figure 3 and Figure 4 The frame 1 has a feeding port 15, and the baking mechanism 10 includes a baffle 6, which is movably connected to the frame 1. The baffle 6 can selectively close the feeding port 15.

[0047] In practical applications, after the capacitors are baked, they need to be removed and new capacitors placed in. Therefore, the frame 1 has a feeding port 15. The feeding port 15 serves as both the part for removing the baking tray 4 from the frame 1 and the part for placing the new baking tray 4. That is, the feeding and discharging functions of the frame 1 are integrated in the same location. After feeding or discharging is completed, the baffle 6 is placed over the feeding port 15 to seal it, prevent hot air from flowing out of the feeding port 15, which would affect the baking efficiency, reduce heat loss, and maintain the temperature stability of the frame 1.

[0048] See Figure 5 The feed inlet 15 is located on the side of the frame 1 and near the bottom of the frame 1. Side feeding facilitates connection with conveyor belts or robotic arms to achieve horizontal material transport, while bottom feeding keeps the material away from the high-temperature area at the top, allowing operators to load materials without having to put their arms into the high-temperature cavity, thus improving safety.

[0049] See Figure 6 The baking tray 4 has through holes 41 penetrating its two opposite surfaces, and the through holes 41 and the air inlet 16 are arranged opposite to each other; the area of ​​the air inlet 16 is smaller than the area of ​​the through holes 41.

[0050] In practical applications, the baking tray 4 is provided with through holes 41, which allow hot air to pass through. This allows hot air to rise from the bottom air inlet 16 and directly penetrate the capacitor components, reducing local temperature differences. In the multi-layer baking tray 4 structure, the through holes 41 are designed to form a vertical hot air channel. Combined with the fan circulation path, this enables materials in each layer to be heated synchronously, improving mass production efficiency.

[0051] Furthermore, the area of ​​the through hole 41 is larger than that of the air inlet hole 16. The increased area of ​​the through hole 41 can reduce airflow resistance, allowing hot air to penetrate the capacitor components more quickly and form a circulation. If the area of ​​the through hole 41 is smaller than that of the air inlet hole 16, the airflow may accumulate in the baking cavity, forming a local high-pressure area. The larger through hole 41 can balance the airflow pressure and ensure that the hot air evenly covers the surface of the capacitor components.

[0052] Unlike existing technologies, this application provides a baking mechanism 10 and an impregnation device. The impregnation device includes a baking mechanism 10, an impregnation mechanism 20, a feeding mechanism 30, and a fixed frame 40. Both the baking mechanism 10 and the impregnation mechanism 20 are connected to the fixed frame 40. The fixed frame 40 has a first station and a second station. The impregnation mechanism 20 and the fixed frame 40 are slidably connected, and the impregnation mechanism 20 can selectively slide to the first station or the second station. The feeding mechanism 30 is used to transport the material in the baking mechanism 10 to the impregnation mechanism 20 located at the second station. The baking mechanism 10 includes a frame 1 and a fan. The frame 1 has an air inlet 16 and an exhaust 17. The frame 1 has a receiving cavity for accommodating multiple baking trays 4 arranged sequentially along the height direction of the frame 1. The air outlet of the fan is connected to the air inlet 16, and the air inlet of the fan is connected to the exhaust 17. Compared to existing technologies, the baking mechanism 10 of this application uses a fan for baking. The fan forces the hot air to circulate, allowing heat to quickly penetrate to every corner of the capacitor components, reducing local temperature differences and ensuring that each layer is heated evenly when baking multiple layers at the same time. Compared to traditional static heating, the dynamic air delivery of the fan can reduce the problem of uneven heat distribution caused by material accumulation or obstruction.

[0053] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
