Description

Technical Field

[0001] This invention relates to the field of motor impregnation equipment technology, specifically to an insulating impregnation equipment for automotive motors. Background Technology

[0002] Electric vehicles are vehicles that use an onboard power source to drive their wheels with an electric motor and meet all road traffic and safety regulations. The production process of electric vehicles requires the use of an electric motor, which converts electrical energy into mechanical energy, driving the wheels and working devices via a transmission system or directly.

[0003] When manufacturing automobile motors, in order to ensure the insulation effect of the internal insulating parts of the motor rotor, it is necessary to impregnate the internal insulating parts of the motor rotor with varnish. Impregnation increases the contact area between the varnish and the insulating parts, thereby improving the insulation effect of the motor rotor after impregnation.

[0004] A Chinese patent application with publication number CN116131555A discloses a device for impregnating and baking motor insulation rings. The device includes two sets of paint tanks, with a base assembly positioned between them. The base assembly has a vertical groove inside, and a vertical plate assembly is rotatably mounted inside the groove. A connecting shaft assembly is mounted on the top of the vertical plate assembly, and the connecting shaft assembly is engaged with the base assembly. Both ends of the connecting shaft assembly are threadedly connected to end clamping plate assemblies. This invention achieves quick assembly and disassembly of the motor insulation ring through simple clamping, while simultaneously fixing both sides of the motor insulation ring with a first and second clamping plate to prevent deformation during impregnation and baking.

[0005] However, this motor insulation impregnation equipment has the following drawbacks in practical use: 1. In existing motor insulation impregnation equipment, after impregnating the rotor inside the motor, some of the varnish adheres to the surface of the rotor. Traditional solutions typically use a dripping method to recover the excess varnish, reducing waste and protecting the working environment. However, in practice, this method has several drawbacks. First, the dripping process requires a considerable amount of time for varnish recovery, affecting the efficiency of impregnating the motor rotor. Second, during dripping, the varnish is prone to irregular dripping due to vibrations generated by the equipment's operation, often ending up on the outside of the equipment. 2. Existing motor insulation impregnation equipment requires heating and baking the rotor after impregnation to ensure the varnish adheres firmly to its surface. However, the gas used for heating the rotor is difficult to utilize, resulting in low energy efficiency. Furthermore, moisture inside the rotor before impregnation hinders varnish adhesion to rotor components, affecting the impregnation effect. Summary of the Invention

[0013] As a preferred embodiment of the present invention, the inclined discharge assembly includes: The lower housing is located on the side of the impregnation tank. A vertical base is mounted on one side of the top of the lower housing with screws, and an inclined plate is mounted on the side of the vertical base.

[0014] As a preferred embodiment of the present invention, the gear blower assembly includes: The system includes multiple upper frames, each mounted on top of the vertical base with screws. A linear motor is mounted on the side of one of the upper frames, and the output of the linear motor is connected to a linear shaft.

[0017] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In insulating impregnation equipment for automotive motors, after impregnating the motor rotor, excess paint on the rotor surface needs to be removed to reduce waste. This is achieved by activating a linear motor to drive two fan blades (connected by gears) to rotate in the same direction. This blows air onto the motor rotor (which has undergone impregnation), improving the efficiency of cleaning the rotor surface. Simultaneously, excess paint falling onto the inclined plate is actuated by the fan blades, causing a rubber impact rod to reciprocate and collide with the inclined plate. This accelerates the fall of excess paint into the impregnation tank for recycling, reducing waste and lowering the cost of impregnating the motor rotor. 2. In the insulation impregnation equipment used for automotive motors, after the motor rotor completes the impregnation process, it needs to be moved into the drying chamber. The heating module, driven by the battery equipment, heats and dries the rotor inside the drying chamber, ensuring the paint adhering to the rotor's surface adheres firmly. Simultaneously, the hot air is transferred to the preheating chamber via an electric fan, preheating the rotor (to be impregnated) and removing moisture and oil from its surface, ensuring the effectiveness of subsequent paint treatment. Furthermore, the gas (heating) in the preheating chamber can be moved by the blower blades to one side of the motor rotor and inclined plate when needed. This enhances the paint removal process on the rotor (increasing paint activity and curing speed), leading to a faster formation of a strong insulation layer. It also increases the activity and flow rate of paint falling onto the inclined plate, preventing it from solidifying due to cooling. 3. In the insulation impregnation equipment for automotive motors, when driving the automotive rotor for impregnation, the structure holding and fixing the motor rotor can be moved in a circular motion by driving a circulating belt. On the one hand, this moves the motor rotor into the impregnation tank, inclined plate, and drying chamber, automatically realizing the impregnation, dripping, and drying operations of the motor rotor, thus improving the intelligence level of the equipment. On the other hand, while one automotive rotor is being dripped and dried, another automotive rotor can undergo the corresponding impregnation and dripping operations, further improving the efficiency of insulation impregnation of the motor rotor. 4. In the insulating impregnation equipment used for automotive motors, the lifting block can be driven by an electric cylinder to move up and down, automatically clamping and fixing the motor rotor shaft. This automatically clamps and fixes multiple parts of the motor rotor, ensuring stability when the motor rotor moves in a circular motion and up and down, and preventing internal parts of the motor rotor from falling off during the movement.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] Please see Figures 1-12An insulating impregnation device for automotive motors includes a frame 10 and an impregnation tank 20. A clamping and conveying structure 30 is installed at the bottom of the frame 10, and a motor rotor is clamped and fixed at the bottom of the clamping and conveying structure 30. A heating and drying assembly 40 is provided on one side below the frame 10, and the motor rotor is supported and positioned on the top of the heating and drying assembly 40. An impregnation dripping mechanism 50 is provided on the side of the heating and drying assembly 40, and an impregnation tank 20 is provided on the side of the impregnation dripping mechanism 50. There are two impregnation tanks 20. The impregnation dripping mechanism 50 includes an inclined discharge assembly 60, which is installed on the side of the impregnation tank 20. A gear blower assembly 70 is installed on one side of the top of the inclined discharge assembly 60, and the gear blower assembly 70 is oriented towards the motor rotor. A circulating collision assembly 80 is installed outside the gear blower assembly 70 and extends into the interior of the inclined discharge assembly 60. The circulating collision assembly 80 performs collision processing on the inclined discharge assembly 60.

[0023] The working principle described above is as follows: When performing varnishing on the rotor components inside the motor to ensure the insulation effect of the motor rotor, the assembled motor rotor is first moved into the heating and drying assembly 40. The operation of the internal components of the heating and drying assembly 40 preheats the motor rotor, removing moisture and oil from its surface. This ensures that the varnish adheres more easily to the surface of the motor rotor when it is subsequently moved into the varnishing tank 20 for varnishing. Simultaneously, during the varnishing process, the clamping and conveying structure 30 clamps and fixes the motor rotor, and moves it into the varnishing tank 20 via a circular motion. The rotor then moves to the side of the gear blower assembly 70 to accelerate the removal of excess varnish from the surface of the motor rotor. The removed varnish is then moved back into the varnishing tank 20 via the inclined discharge assembly 60, improving the efficiency of varnishing and dripping on the motor rotor. After dripping, the motor rotor moves into the heating and drying assembly 40 to dry the varnish on its surface, allowing the varnish to adhere firmly to the motor rotor's surface. The heat from the heating and drying component 40 can be moved to the side that preheats the motor rotor, thus improving the utilization rate of heat.

[0024] For details, please refer to the following: Figure 5 and Figure 6The clamping and conveying structure 30 includes a servo motor 301, which is mounted on one side of the top of the frame 10. The output end of the servo motor 301 is connected to a main shaft 302 extending to the bottom of the frame 10. A circulating gear 303 is mounted on the outside of the main shaft 302. There are two circulating gears 303, and both circulating gears 303 are rotatably connected to the bottom of the frame 10. A circulating belt 304 is meshed with the outside of the two circulating gears 303 and is movably disposed at the bottom of the frame 10. A guide bracket 305 is provided on the outside of the circulating belt 304 and is mounted at the bottom of the frame 10. A circulating seat 306 is mounted on the side of the circulating belt 304 and is movably disposed on the outside of the guide bracket 305. A lifting assembly 307 is mounted on the bottom of the circulating seat 306 by screws.

[0025] In an embodiment of the present invention, the lifting assembly 307 includes a mounting bracket 3071, which is mounted on the bottom of the circulation seat 306 by screws. A lifting cylinder 3072 is installed inside the mounting bracket 3071. The output end of the lifting cylinder 3072 extends to the bottom of the circulation seat 306 and is connected to a mounting plate 30720. A guide rod 3073 is installed on both sides of the top of the mounting plate 30720 and passes through a guide seat 3074. The guide seat 3074 is installed on the left and right sides of the mounting bracket 3071.

[0026] In the above embodiments, when it is necessary to move the motor rotor up and down, the lifting cylinder 3072 is activated to operate, causing the mounting plate 30720 connected to the output end of the lifting cylinder 3072 to move up and down, ensuring that the motor rotor clamped and fixed at the bottom of the mounting plate 30720 can move up and down. The guide rod 3073 moves up and down along the mounting plate 30720, guiding the movement of the mounting plate 30720 and ensuring the stability of the motor rotor during up and down movement.

[0027] In the insulating impregnation apparatus for automotive motors of the present invention, when the motor rotor is moved, the servo motor 301 is activated, driving the main shaft 302 connected to the output end of the servo motor 301 to rotate, causing the circulating gear 303 mounted at the bottom of the main shaft 302 to rotate. When the circulating gear 303 rotates, the circulating belt 304 meshing with its outer side operates, allowing the circulating seat 306 mounted on the side of the circulating belt 304 to move outside the guide bracket 305. The efficiency of impregnating the motor rotor is improved through the circular movement of the motor rotor.

[0028] For details, please refer to the following: Figure 6 and Figure 7Electric cylinders 30721 are installed on both sides of the bottom of the mounting plate 30720. The output end of the electric cylinders 30721 is connected to the lifting block 30722. The left and right sides of the lifting block 30722 are rotatably connected to the movable arm 30723.

The bottom of the bending arm 30724 is rotatably connected to the top of the vertical rod 30725. The vertical rod 30725 is installed at the bottom of the mounting plate 30720. A clamping claw 30726 is installed at the bottom of the bending arm 30724. The inner side of the clamping claw 30726 clamps and fixes the motor rotor.

[0029] In the insulating impregnation equipment for automotive motors of the present invention, when clamping and fixing the motor rotor, the electric cylinder 30721 is activated, driving the lifting block 30722 connected to the output end of the electric cylinder 30721 to move up and down. During the lifting and lowering movement of the lifting block 30722, the movable arms 30723 rotatably connected to its left and right sides rotate, driving the bent arm 30724 rotatably connected to the bottom of the movable arm 30723 to operate (outward or inward), so that the clamping claw 30726 can clamp and fix the rotating shaft portion of the motor rotor, thereby realizing the clamping and fixing operation of the motor rotor. The rotatable connection between the vertical rod 30725 and the bent arm 30724 ensures the stability and firmness of the bent arm 30724 during rotation.

[0030] For details, please refer to the following: Figure 8 The heating and drying assembly 40 includes a work box 401, which is installed on one side of the bottom of the frame 10. A partition 402 is provided at the center of the top of the work box 401.

[0032] In the insulating impregnation apparatus for automotive motors of the present invention, after the motor rotor completes the impregnation process, it can be placed on top of the first support 404. The heating module 403 is driven by the battery device 4031 to heat the air inside the drying chamber 4022, thereby heating and drying the motor rotor inside the drying chamber 4022. Part of the drying and heating gas can be transported through the connection port 405 to the preheating chamber 4021 via an electric fan 406, preheating the motor rotor inside the preheating chamber 4021 and cleaning oil and moisture from the surface of the motor rotor.

[0033] For details, please refer to the following: Figure 9 and Figure 11 The inclined discharge assembly 60 includes a lower housing 601, which is disposed on the side of the impregnation tank 20.

The bottom of the inclined plate 603 is installed on the top of the impregnation tank 20. A gear blower assembly 70 is installed on the top of the vertical seat 602.

[0034] In the insulating impregnation equipment for automotive motors of the present invention, the design of the inclined plate 603 allows the dripping paint to be moved back into the impregnation tank 20 during the dripping operation on the motor rotor, ensuring that the paint can be reused.

[0035] For details, please refer to the following: Figure 9 , Figure 10 and Figure 11 The gear blower assembly 70 includes an upper frame 701, of which multiple upper frames 701 are mounted on the top of a vertical base 602 by screws. A linear motor 702 is mounted on the side of one upper frame 701, and the output end of the linear motor 702 is connected to a linear shaft 703, which extends to the outside of the vertical base 602. A main gear 704 is mounted on the side of the linear shaft 703 and is rotatably connected to the outside of the vertical base 602. Driven gears 705 are meshed on the left and right sides of the main gear 704. A movable shaft 706 extending to the inside of the vertical base 602 is mounted on the side of the driven gear 705, which is rotatably connected to the inside of the upper frame 701. Blower fan blades 707 are mounted on the side of the movable shaft 706.

[0036] In an embodiment of the present invention, a circulating collision assembly 80 is installed on the outside of the linear shaft 703 located inside the upper frame 701. The circulating collision assembly 80 extends to the bottom of the vertical seat 602, and the bottom of the circulating collision assembly 80 abuts against one side of the bottom of the inclined plate 603. The blower fan blade 707 is disposed above the inclined plate 603.

[0037] In the insulating impregnation apparatus for automotive motors of the present invention, when removing the varnish from the surface of the motor rotor, a linear motor 702 is started to operate, driving the linear shaft 703 connected to the output end of the linear motor 702 to rotate, thereby causing the main gear 704 connected to the bottom of the linear shaft 703 to rotate. When the main gear 704 rotates, the driven gears 705 meshing on its left and right sides can rotate, causing the movable shaft 706 and the blower fan blades 707 mounted on the side of the driven gears 705 to rotate, thus performing the varnish removal operation on the motor rotor mounted on its side.

[0038] For details, please refer to the following: Figure 9 , Figure 10 and Figure 11 The cyclic collision assembly 80 includes two bevel gears 801, which are meshed together and movably disposed inside the vertical seat 602. One bevel gear 801 is mounted on the outside of the linear shaft 703. A vertical shaft 802 is mounted at the bottom of the other bevel gear 801 and extends below the vertical seat 602. A half-gear 80 is mounted at the bottom of the vertical shaft 802. 3. The half gear 803 is rotatably connected to the top of the lower housing 601; the tooth frame 804 is meshed with the outside of the half gear 803, and the tooth frame 804 is movably set inside the horizontal rod 805. The horizontal rod 805 is installed on the top of the lower housing 601. The tooth frame 804 has teeth on both the left and right sides of its inner wall, and a rubber collision rod 806 is installed on the side of the tooth frame 804. The top of the rubber collision rod 806 abuts against one side of the bottom of the inclined plate 603.

[0039] In the insulating impregnation equipment for automotive motors of the present invention, when the linear shaft 703 rotates, the bevel gear 801 mounted on its outer side can rotate, driving another bevel gear 801 meshing with the side of the bevel gear 801 to rotate. When the other bevel gear 801 rotates, the vertical shaft 802 connected to its bottom can rotate, causing the half gear 803 connected to the bottom of the vertical shaft 802 to rotate. At this time, when the half gear 803 rotates, when it meshes with the teeth on one side of the inner wall of the tooth frame 804, it can drive the tooth frame 804 and the rubber impact rod 806 to move. Through the design of the teeth on both sides of the inner wall of the tooth frame 804, the tooth frame 804 and the rubber impact rod 806 can reciprocate, vibrating the inclined plate 603 set on the top of the rubber impact rod 806, ensuring that the paint liquid falling on the top of the inclined plate 603 can move normally into the impregnation tank 20.

[0040] As another embodiment of the present invention, please refer to the following: Figure 12 A gas heating and circulation system 90 is installed on the outside of the impregnation tank 20. The inlet and outlet of the gas heating and circulation system 90 are connected to a circulation pipe 901. The circulation pipe 901 extends into the interior of the impregnation tank 20. A flow pipe 902 is provided on the side of the circulation pipe 901. The flow pipe 902 is installed on the side of the work box 401. An electric fan 406 is installed on the side of the flow pipe 902 and mounted on the side of the preheating chamber 4021.

[0041] In the insulating impregnation equipment for automotive motors of the present invention, the design of the flow pipe 902 allows the gas inside the preheating chamber 4021 to be transferred to one side of the circulation pipe 901, preheating the surface of the circulation pipe 901 and preventing rapid heat loss of the circulating gas inside the circulation pipe 901 due to sudden temperature changes in the internal and external environments. Simultaneously, the heating treatment of the paint solution inside the impregnation tank 20 enhances the activity of the paint solution during impregnation of the motor rotor, facilitating the rapid formation of an insulating layer on the outer side of the motor rotor.

[0042] Therefore, any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the technical solution and inventive concept of this invention, should be covered within the protection scope of this invention.
