Description

Technical Field

[0001] The present invention belongs to the technical field of motor production, and particularly relates to a high-efficiency motor stator insulation vacuum impregnation equipment. Background Art

[0002] A motor (commonly known as a "motor") is an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. It is divided into a motor (symbol M) and a generator (symbol G).

[0003] The motor stator is an important part of motors such as generators and starters. The stator is an important part of the motor. The stator consists of three parts: a stator core, a stator winding, and a frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate (output) current. The Chinese motor parts market is distributed in the southeastern coastal areas and the Yangtze River Delta region. According to the relationship between the number of magnetic poles of the motor and the actual number of magnetic poles formed by the winding distribution, the stator winding can be divided into two types: the salient pole type and the fractional pole type.

[0004] In a Chinese patent with the publication number CN202353406U, a motor impregnation equipment is disclosed, which includes an air pressure pump, a paint storage tank, a stator product impregnation device, a junction box, a control cabinet, a vacuum indicator window, and a vacuum pump; one end of the paint storage tank is connected to the air pressure pump, and the other end is connected to the input end of the stator product impregnation device; the output end of the stator product impregnation device is connected to one end of the vacuum indicator window; the other end of the vacuum indicator window is connected to the vacuum pump; the stator product impregnation device is connected to the junction box; and the junction box is connected to the control cabinet.

[0005] However, when the above device is in use, the following problems exist:

[0006] When the stator product enters the impregnation device, it will carry a part of gas, and these gases will be mixed with the paint in the impregnation device, which will cause the paint to be contaminated. The contaminated paint cannot be used for a long time, resulting in the need to replace the paint according to the actual situation, which leads to a higher amount of paint input and the cost of paint input during the use of the device; therefore, the present application proposes a high-efficiency motor stator insulation vacuum impregnation equipment. Summary of the Invention

[0007] The purpose of the present invention is to provide a high-efficiency motor stator insulation vacuum impregnation equipment to solve the problem that when the stator product enters the impregnation device, it will carry a part of gas, and these gases will be mixed with the paint in the impregnation device, which will cause the paint to be contaminated and the paint cannot be used for a long time as mentioned in the above background art.

[0008] To achieve the above object, the present invention provides the following technical solutions. A high-efficiency motor stator insulation vacuum impregnation equipment includes an impregnation tank, a feeding cylinder, and a vacuum pump. The feeding cylinder is located at the top of the impregnation tank and is movably connected to the impregnation tank. The vacuum pump is connected to the feeding cylinder;

[0009] A feeding rack is provided at the top of the impregnation tank, and a driving motor connected to the feeding cylinder is provided on the feeding rack;

[0010] An opening is provided on one side of the feeding cylinder, and an arc-shaped door is provided at the position of the feeding cylinder corresponding to the opening. The arc-shaped door is used to open and close the opening;

[0011] A positioning mechanism, a mounting rack, a top plate, a connecting rope, and a winding device are provided inside the feeding cylinder;

[0012] The top plate is provided inside the feeding cylinder, and an adsorption mechanism is provided at the top plate;

[0013] The winding device is provided on the top plate, the connecting rope is wound inside the winding device, and the connecting rope is connected to the mounting rack.

[0014] In a further technical solution, the feeding cylinder is inserted into the feeding rack, and the feeding cylinder and the feeding rack can rotate relative to each other.

[0015] In a further technical solution, side plates are provided on the feeding cylinder. There are two side plates, and the two side plates are respectively connected to the outer walls at both ends of the feeding cylinder. The arc-shaped door is located between the two side plates.

[0016] In a further technical solution, the positioning mechanism includes an inner tube, a support block, a support plate, a lifting block, a lifting rod, and a telescopic rod. An installation hole is provided inside the stator body. The size of the inner tube is smaller than the size of the installation hole. A guiding groove is provided inside the inner tube, and the support block cooperates with the guiding groove.

[0017] In a further technical solution, at least two support blocks are provided, and the two support blocks are symmetrically distributed. The guiding groove is perpendicular to the axis of the installation hole.

[0018] In a further technical solution, a storage frame is provided on the side of the top plate facing the mounting rack. The storage frame is aligned with the mounting rack up and down, and the adsorption mechanism is provided inside the storage frame.

[0019] In a further technical solution, the support block is movably connected to the support plate, the other end of the support plate is movably connected to the lifting block, the top of the lifting block is connected to the lifting rod, and the lifting rod is connected to the output end of the telescopic rod. The telescopic rod is provided on the mounting rack.

[0020] In a further technical solution, an arc-shaped portion is provided at one end of the support block away from the inner tube, and the arc-shaped portion fits with the inner wall of the installation hole.

[0021] In a further technical solution, the adsorption mechanism includes a plug rod. The plug rod is arranged at the top of the mounting frame. The plug rod cooperates with the storage frame. An electromagnet is arranged in the storage frame, and an adsorption plate is arranged at the top of the plug rod.

[0022] In a further technical solution, a conical frame is arranged in the feeding cylinder.

[0023] Beneficial effects:

[0024] For a high-efficiency motor stator insulation vacuum impregnation device provided by the present invention, when the telescopic rod is started, it can drive the lifting block and the lifting rod to move up and down. The lifting block can pull the support block to move along the guiding groove through the support plate, so that the support block moves towards or away from the inner wall of the mounting hole. When the support block approaches the inner wall of the mounting hole and finally abuts against the inner wall of the mounting hole, multiple support blocks cooperate with each other to clamp the stator body, and when the support block moves away from the inner wall of the mounting hole, the stator body is released by the positioning mechanism.

[0025] For a high-efficiency motor stator insulation vacuum impregnation device provided by the present invention, when the winding device is started, the connecting rope can be wound up and released. When the connecting rope is released and the adsorption mechanism is closed at the same time, at this time, the mounting frame, the positioning mechanism and the stator body fall under the action of gravity until the stator body is completely immersed in the paint. After a certain period of time, the winding device is started again to wind up the connecting rope. The connecting rope can pull the mounting frame, the positioning mechanism and the stator body to move up, lift the stator body out of the paint, and finally receive it into the feeding cylinder. The feeding cylinder rotates around the feeding frame, and when the feeding cylinder rotates to have its opening facing upwards, the stator body can be taken out from the upper side. During the process of impregnating the stator body with paint, the external air is sucked away by the vacuum pump and will not enter the interior of the impregnation tank and will not contact the paint in the impregnation tank. In this way, the paint can be stored for a longer time and the number of uses is also extended accordingly, which can reduce the input of paint. Description of the drawings

[0037] The following is a detailed description of the specific implementation of the present invention, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0038] As Figures 1-9 shown, a high-efficiency motor stator insulation vacuum impregnation equipment provided by an embodiment of the present invention includes an impregnation tank 1, a loading cylinder 2, a vacuum pump 3, and a feed pipe 5. The loading cylinder 2 is located at the top of the impregnation tank 1 and is movably connected to the impregnation tank 1. The vacuum pump 3 is connected to the loading cylinder 2, and the vacuum pump 3 is used to pump out the gas in the loading cylinder 2 to prevent external gas from entering the interior of the impregnation tank 1 and thus damaging the paint in the impregnation tank 1.

[0039] It should be noted that the feed pipe 5 is connected to the impregnation tank 1, and the feed pipe 5 is used to send the paint into the interior of the impregnation tank 1, and the stator body 6 is completely immersed in the paint in the impregnation tank 1.

[0040] More specifically, a loading rack 4 is provided at the top of the dipping tank 1. The loading cylinder 2 is inserted into the loading rack 4, and the loading cylinder 2 and the loading rack 4 can rotate relative to each other. A driving motor is provided on the loading rack 4, and the output end of the driving motor is connected to the loading cylinder 2. The driving motor can drive the loading cylinder 2 to rotate, thereby adjusting the orientation of the loading cylinder 2.

[0041] For reference, Figures 4-6 An opening 201 is provided on one side of the loading cylinder 2, and an arc-shaped door 202 is provided at the position of the loading cylinder 2 corresponding to the opening 201. The arc-shaped door 202 is used to open and close the opening 201. Side plates 203 are provided on the loading cylinder 2. There are two side plates 203, and the two side plates 203 are respectively connected to the outer walls at both ends of the loading cylinder 2. The arc-shaped door 202 is located between the two side plates 203.

[0042] In order to clamp and release the stator body 6 and send the stator body 6 into the dipping tank 1, a positioning mechanism 7, a mounting rack 8, a top plate 9, a storage frame 10, a connecting rope 13, and a winding device 14 are provided in the loading cylinder 2.

[0043] For reference, Figures 7-9 The positioning mechanism 7 includes an inner tube 701, a support block 702, a support plate 703, a lifting block 704, a lifting rod 705, and a telescopic rod 706. An installation hole is provided in the stator body 6, and the installation hole is used to connect the stator shaft. The size of the inner tube 701 is smaller than the size of the installation hole. At least two support blocks 702 are provided, and the two support blocks 702 are symmetrically distributed. A guide groove is provided in the inner tube 701, and the support block 702 cooperates with the guide groove. The guide groove is perpendicular to the axis of the installation hole;

[0044] Specifically, an arc-shaped portion is provided at the end of the support block 702 away from the inner tube 701, and the arc-shaped portion fits against the inner wall of the installation hole. The support block 702 is movably connected to the support plate 703, and the other end of the support plate 703 is movably connected to the lifting block 704. The top of the lifting block 704 is connected to the lifting rod 705, and the lifting rod 705 is connected to the output end of the telescopic rod 706. The telescopic rod 706 is provided on the mounting rack 8.

[0045] When the telescopic rod 706 is activated, it can drive the lifting block 704 and the lifting rod 705 to move up and down. The lifting block 704 can pull the support block 702 to move along the guide groove through the support plate 703, so that the support block 702 moves closer to or away from the inner wall of the installation hole. The support block 702 finally abuts against the inner wall of the installation hole when it is close to the inner wall of the installation hole. Multiple support blocks 702 cooperate with each other to clamp the stator body 6, while when the support block 702 moves away from the inner wall of the installation hole, the stator body 6 is released by the positioning mechanism 7.

[0046] For reference, Figures 7-9, the top plate 9 is arranged on one side of the feeding cylinder 2 far away from the opening 201. The positioning mechanism 7 is arranged on the mounting rack 8. A storage frame 10 is arranged on the side of the top plate 9 facing the mounting rack 8. The storage frame 10 is vertically aligned with the mounting rack 8. An adsorption mechanism is arranged in the storage frame 10. When the adsorption mechanism is started, it can adsorb the mounting rack 8 at the storage frame 10. Specifically, the adsorption mechanism includes a plug rod. The plug rod is arranged on the top of the mounting rack 8 and cooperates with the storage frame 10. An electromagnet 11 is arranged in the storage frame 10. An adsorption plate 12 is arranged on the top of the plug rod. When the electromagnet 11 is started, it can suck the adsorption plate 12, and then fix the positions of the mounting rack 8, the positioning mechanism 7, and the stator body 6.

[0047] In order to send the stator body 6 into the paint inside the dipping tank 1, a winding device 14 is arranged in the top plate 9. A connecting rope 13 is wound in the winding device 14, and the end of the connecting rope 13 is connected to the mounting rack 8.

[0048] When the winding device 14 is started, the connecting rope 13 can be retracted and released. When the connecting rope 13 is released and the adsorption mechanism is closed at the same time, at this time, the mounting rack 8, the positioning mechanism 7, and the stator body 6 fall under the action of gravity until the stator body 6 is completely immersed in the paint. After a certain period of time, the winding device 14 is started again to retract the connecting rope 13. The connecting rope 13 can pull the mounting rack 8, the positioning mechanism 7, and the stator body 6 to move upward, fish out the stator body 6 from the paint, and finally receive it into the feeding cylinder 2. The feeding cylinder 2 rotates around the feeding rack 4. When the feeding cylinder 2 rotates until the opening 201 faces upward, the stator body 6 can be taken out from the upper side. During the dipping process of the stator body 6, the external air is sucked away by the vacuum pump 3 and will not enter the inside of the dipping tank 1 and will not contact the paint in the dipping tank 1. In this way, the paint can be stored for a longer time, and the number of uses is also extended accordingly, which can reduce the input of paint.

[0049] In order to make the stator body 6 more stable after entering the feeding cylinder 2, a conical frame 15 is arranged in the feeding cylinder 2. When the adsorption mechanism is started, the upper end surface of the stator body 6 abuts against the outer wall of the conical frame 15. A cross plate 16 is arranged at the top of the conical frame 15, and the cross plate 16 is connected to the inner wall of the feeding cylinder 2.

[0050] In summary: The embodiment of the present invention provides a high-efficiency motor stator insulation vacuum dipping device. When the telescopic rod 706 is started, it can drive the lifting block 704 and the lifting rod 705 to move up and down. The lifting block 704 can pull the support block 702 to move along the guiding groove through the support plate 703, so that the support block 702 moves toward or away from the inner wall of the mounting hole. The support block 702 finally abuts against the inner wall of the mounting hole when it approaches the inner wall of the mounting hole. Multiple support blocks 702 cooperate with each other to clamp the stator body 6, while when the support block 702 moves away from the inner wall of the mounting hole, the stator body 6 is released by the positioning mechanism 7.

[0051] Start the rewinding device 14, which can wind up and release the connecting rope 13. When the connecting rope 13 is released, the adsorption mechanism is closed at the same time. At this time, the mounting frame 8, the positioning mechanism 7, and the stator body 6 fall under the action of gravity until the stator body 6 is completely immersed in the paint. After a certain period of time, start the rewinding device 14 again to wind up the connecting rope 13. The connecting rope 13 can pull the mounting frame 8, the positioning mechanism 7, and the stator body 6 upward to lift the stator body 6 out of the paint and finally receive it into the feeding cylinder 2. The feeding cylinder 2 rotates around the feeding frame 4. When the feeding cylinder 2 rotates until the opening 201 faces upward, the stator body 6 can be taken out from the upper side. During the process of the stator body 6 being immersed in the paint, the external air is sucked away by the vacuum pump 3 and will not enter the interior of the paint dipping tank 1 and will not contact the paint in the paint dipping tank 1. In this way, the paint can be stored for a longer time and the number of uses is also extended accordingly, which can reduce the input of paint.

[0052] The above-disclosed are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
