Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically a coil impregnation equipment for producing a mid-mounted brushless gear motor for electric vehicles. Background Technology

[0002] Motor production refers to the entire process of manufacturing motors, including raw material preparation, component processing (such as stator core fabrication and winding), assembly, and testing. For electric vehicles, a mid-mounted brushless geared motor is a type of motor installed in the middle of the electric vehicle that uses brushless technology and has gear transmission. In the production process of this motor, in order to increase the insulation performance of its coils and improve their moisture resistance and corrosion resistance, it is often necessary to impregnate the coils with varnish. At this time, appropriate impregnation equipment is required.

[0003] According to the utility model patent application CN218102916U, a coil impregnation device for micro motor production is disclosed. Although this device can impregnate coils for micro motor production, significantly improving the efficiency and shortening the processing time, and effectively avoiding the drawbacks of conventional direct clamping coil impregnation where the clamping part cannot be properly impregnated, multiple impregnations are generally required to ensure the impregnation effect, and a baking operation is required between each impregnation. However, the current impregnation device lacks an automatic baking structure for easy baking of the coil, resulting in the need to remove the coil after each impregnation for separate baking, and then put it back into the impregnation device, making the impregnation process time-consuming and labor-intensive. Therefore, we provide a coil impregnation device for the production of mid-drive brushless gear motors for electric vehicles to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a coil impregnation equipment for the production of a mid-mounted brushless gear motor for electric vehicles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coil impregnation equipment for producing a mid-mounted brushless gear motor for electric vehicles, comprising an impregnation tank, wherein an automatic baking mechanism is provided above the impregnation tank;

[0006] The automatic baking mechanism includes a baking oven, a protective door hinged to the front of the baking oven, a button controller fixedly connected to the left side of the baking oven, a vent on the upper surface of the baking oven, two air ducts fixedly connected to the inner wall of the baking oven, a fan and a heating wire fixedly connected to the inner wall of each air duct, a multi-stage electric telescopic rod fixedly connected to the inner top wall of the baking oven, a paint impregnation cage slidably connected inside the baking oven, and a hollow limiting base plate fixedly connected to the bottom surface of the paint impregnation cage.

[0007] Furthermore, the upper surface of the impregnation cage is fixedly connected to the telescopic end of the multi-stage electric telescopic rod, the outer surface of the hollow limiting base plate is slidably connected to the interior of the impregnation box, the upper surface of the hollow limiting base plate is in contact with the bottom surface of the baking oven, an electromagnetic valve is provided on the outside of the impregnation box, the output end of the electromagnetic valve is fixedly connected to a drain pipe, the input end of the electromagnetic valve and the left side of the impregnation box are fixedly connected to a connecting pipe, and the multi-stage electric telescopic rod, two fans, two heating wires and the electromagnetic valve are all electrically connected to the button controller through wires.

[0008] Furthermore, the bottom surface of the impregnation tank is fixedly connected to two elongated bases, and each elongated base is fixedly connected to an anti-slip pad.

[0009] Furthermore, the protective door is fixedly connected to two fixing rods on the front, and the baking oven is fixedly connected to two limiting rods on the front.

[0010] Furthermore, the outer side of the protective door is provided with two limiting plates, the inner wall of each limiting plate is rotatably connected to the outer surface of the fixing rod, and the interior of each limiting plate is engaged with the outer surface of the limiting rod.

[0011] Furthermore, a handle support is fixedly connected to the front of the protective door, and a pull rod is fixedly connected to the inner wall of the handle support.

[0012] Furthermore, a grip is provided inside the handle support, and the inner wall of the grip is rotatably connected to the outer surface of the pull rod.

[0013] Compared with existing technologies, the coil impregnation equipment for producing a mid-mounted brushless gear motor for electric vehicles has the following advantages:

[0014] This invention utilizes the coordinated components of an impregnation tank, baking oven, protective door, button controller, air duct, vent, multi-stage electric telescopic rod, impregnation cage, perforated limiting base plate, fan, and heating wire. The impregnation tank can hold sufficient varnish for coil impregnation, and the impregnation cage can hold multiple motor coils requiring impregnation. The button controller controls the extension and retraction length of the multi-stage electric telescopic rod and the duration of that length, thereby controlling the up-and-down sliding of the impregnation cage and perforated limiting base plate within the impregnation tank. While the impregnation cage and its coils are immersed in the varnish, the button controller times the impregnation time. After impregnation, the button controller automatically controls the multi-stage electric... The telescopic rod shortens and allows the varnish-impregnating cage to enter the baking oven. At the same time, the button controller controls the fan to blow air into the baking oven and the heating wire to heat up. With the help of the vent, the varnish-impregnated coil in the varnish-impregnating cage is baked until the baking time set by the button controller is reached. Then, the button controller can control the multi-stage electric telescopic rod to extend again, and the varnish-impregnating cage and the coil inside are impregnated again. This achieves multiple varnish impregnation and automatic baking of the coil, and simplifies the coil impregnation process. It avoids the problem of the lack of an automatic baking structure that makes it easy to bake the coil, which requires taking the coil out and baking it separately after each varnish impregnation, and then putting it back into the varnish-impregnating equipment, making the varnish impregnation process time-consuming and laborious.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] This embodiment provides a coil impregnation equipment for the production of a mid-drive brushless gear motor for electric vehicles. This device is used in the coil impregnation process of the mid-drive brushless gear motor. It can automatically bake the coil according to the settings, and can also impregnate the coil again after baking, making the impregnation process convenient, fast and time-saving.

An automatic baking mechanism 2 is installed above the impregnation tank 1. The automatic baking mechanism 2 includes a baking chamber 201. A protective door 202 is movably hinged to the front of the baking chamber 201. The outer surface of the hollow limiting base plate 208 is slidably connected to the interior of the impregnation tank 1. A solenoid valve 5 is installed on the outside of the impregnation tank 1. The output end of the solenoid valve 5 is fixedly connected to a drain pipe 6. The input end of the solenoid valve 5 and the left side of the impregnation tank 1 are fixedly connected to a connecting pipe 7. By installing the solenoid valve 5, it can connect the drain pipe 6 and the connecting pipe 7 after being energized, thereby facilitating the external discharge and replacement of the paint liquid in the impregnation tank 1.

[0024] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 A button controller 203 is fixedly connected to the left side of the baking oven 201. A vent 205 is provided on the upper surface of the baking oven 201. Two elongated bases 3 are fixedly connected to the bottom of the paint dipping tank 1. Each elongated base 3 has an anti-slip pad 4 fixedly connected to its bottom surface. By setting the elongated bases 3, they can be placed on the bottom of the paint dipping tank 1 and increase the length of the paint dipping tank 1 in contact with the ground, thereby increasing the placement stability of the paint dipping tank 1 and the structure above it. The paint dipping tank 1 is also raised to a certain extent, which facilitates the subsequent lifting and handling of the paint dipping tank 1. The anti-slip pads 4 can increase the anti-slip effect of the bottom surface of the elongated bases 3, thereby increasing the placement stability of the entire paint dipping equipment.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The inner wall of the baking oven 201 is fixedly connected to two air ducts 204. Each air duct 204 is fixedly connected to a fan 209 and a heating wire 210. The front of the protective door 202 is fixedly connected to two fixing rods 8. The front of the baking oven 201 is fixedly connected to two limiting rods 9. By setting the fixing rods 8, a rotation base surface can be provided for other limiting structures, thereby increasing the flexibility of the use of the limiting structure. By setting the limiting rods 9, the above-mentioned limiting structure can be limited.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The inner top wall of the baking oven 201 is fixedly connected to a multi-stage electric telescopic rod 206. The multi-stage electric telescopic rod 206, two fans 209, two heating wires 210 and solenoid valve 5 are all electrically connected to the button controller 203 through wires. Two limiting plates 10 are provided on the outer side of the protective door 202. The inner wall of each limiting plate 10 is rotatably connected to the outer surface of the fixed rod 8. The inside of each limiting plate 10 is engaged with the outer surface of the limiting rod 9. By setting the limiting plates 10, they can rotate around the outer surface of the fixed rod 8 and engage with the outer surface of the limiting rod 9, thereby increasing the relative tightness of the protective door 202 and the baking oven 201 when closed.

[0027] Reference Figure 1 , Figure 2 and Figure 4 The oven 201 is slidably connected to a paint impregnation cage 207. The upper surface of the paint impregnation cage 207 is fixedly connected to the telescopic end of the multi-stage electric telescopic rod 206. The front of the protective door 202 is fixedly connected to a handle support 11. The inner wall of the handle support 11 is fixedly connected to a pull rod 12. By providing the pull rod 12, a rotation base surface can be provided for the hand grip structure inside the handle support 11, thereby increasing the flexibility of the hand grip structure. By providing the handle support 11 and the pull rod 12, the protective door 202 can be pulled together with the aforementioned hand grip structure, thereby facilitating the opening of the protective door 202 relative to the oven 201.

[0028] Reference Figure 1 , Figure 2 and Figure 4 The bottom surface of the varnish-impregnating cage 207 is fixedly connected to a hollow limiting base plate 208. The upper surface of the hollow limiting base plate 208 is in contact with the bottom surface of the baking oven 201. The handle support 11 is provided with a handle 13 inside. The inner wall of the handle 13 is rotatably connected to the outer surface of the pull rod 12. By providing the handle 13, it can rotate around the outer surface of the pull rod 12 inside the handle support 11, so that it is convenient to open the protective door 202 relative to the baking oven 201 when it is held by hand.

[0029] Working principle: In use, open the protective door 202 and inject sufficient paint for coil impregnation into the impregnation tank 1. Then, place multiple motor coils to be impregnated in the impregnation cage 207. Operate the button controller 203 to set the extension length and corresponding length holding time of the multi-stage electric telescopic rod 206, thereby controlling the impregnation cage 207 and the hollow limit plate 208 to slide up and down in the impregnation tank 1. While the impregnation cage 207 and its coils are immersed in the paint in the impregnation tank 1, the button controller 203 can time the impregnation time. After impregnation, the button controller 203 will automatically control the multi-stage electric telescopic rod 206 to shorten and allow the impregnation cage 207 to enter the baking oven 201. At the same time, the button controller 203 will control the fan 209 to blow air into the baking oven 201 and the heating wire 210 to heat up, allowing ventilation. With the cooperation of port 205, the coil in the varnish-impregnated cage 207 is baked until the baking time set by the button controller 203 is reached. Then, the button controller 203 will control the multi-stage electric telescopic rod 206 to extend again, and the varnish-impregnated cage 207 and the coil inside it will be varnished again. By operating and setting the parameters in the button controller 203, the varnish-impregnation time, number of varnish-impregnations and baking time of the motor coil can be preset. It is not necessary to repeatedly turn the motor coil. It plays the role of multiple varnish-impregnations and automatic baking of the coil, and simplifies the coil varnish-impregnation process. The design of the coil varnish-impregnation equipment for the production of mid-mounted brushless gear motors for electric vehicles effectively solves the problem that the lack of an automatic baking structure for easy baking of the coil means that after each varnish-impregnation, the coil needs to be taken out and baked separately, and then put back into the varnish-impregnation equipment, which makes the varnish-impregnation process time-consuming and laborious.
