Description

[0002] In an electric motor, the rotor plays a rotating role part, which is often composed of elements such as magnets, wires, etc. After the production of the rotor is completed, impregnation operation is needed. Through the impregnation of the rotor, the gap and air layer of the coil can be filled, and after curing, a continuous and smooth paint film can be formed on the surface of the impregnated winding and components, and the winding is bonded into a whole, which can not only improve the insulation and curing structure of the coil, but also enhance the electrical moisture resistance, heat resistance strength and mechanical strength, etc.

[0003] However, in the actual operation process, due to the high density and viscosity of the paint liquid, the existing impregnation device generally adopts static impregnation, which makes it difficult for the paint liquid to penetrate into the middle part of the rotor coil, and thus the problems of insufficient and uneven impregnation are prone to occur. At the same time, after the impregnation of the rotor is completed, it needs to be transferred and then the surface impregnation of the rotor is cured by using a drying mechanism, which is complicated in operation and prone to reduce the impregnation efficiency of the rotor.

[0018] S1, injecting paint into the paint dipping box for standby;

[0019] S2, controlling the extension of the lifting cylinder, the lifting cylinder drives the U-shaped frame and the placing mechanism to rise, and the placing mechanism is lifted above the paint level;

[0020] S3, removing the bolts on the movable lining plate, slidingly adjusting the position of the movable lining plate according to the type of the motor rotor, fixing the movable lining plate by screwing the bolts into the adjustment holes after the position of the movable lining plate is adjusted, and then placing the motor rotor into the placing groove, which can complete the placement of the motor rotor by covering the placing groove with the baffle;

[0021] S4, controlling the contraction of the lifting cylinder, the lifting cylinder drives the U-shaped frame and the placing mechanism to descend, and the placing mechanism is lowered below the paint level, to complete the paint dipping of the motor rotor;

[0022] S5, when the motor rotor is dipped in paint, the mounting seat reciprocally and regularly moves to the upper side of each placing mechanism in turn.

[0023] S6. During the process of the placement mechanism being lifted to above the level of the impregnation liquid, the adjacent placement mechanism can be tilted by the linkage rope, thereby causing the motor rotor on the adjacent placement mechanism to move in the placement groove to complete the rotation of the motor rotor. At the same time, during the lifting process of the placement mechanism, it is used to increase the flow of impregnation liquid in the impregnation tank.

[0024] S7.

Detailed Implementation

[0040] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0041] like Figures 1 to 10As shown, the motor rotor paint dipping device in an embodiment of the present application comprises a paint dipping box 1, a pair of fixed plates 2, a U-shaped frame 3, a plurality of placing mechanisms 4, a pre-drying mechanism 5, a pair of lifting mechanisms 6 and a plurality of linkage ropes 7. The paint dipping box 1 is used for storing paint dipping. The pair of fixed plates 2 are symmetrically fixed to a pair of side walls of the paint dipping box 1, and a pair of jacking cylinders 201 are installed on the fixed plates 2. The U-shaped frame 3 is connected to free ends of the jacking cylinders 201 and can be lifted in the paint dipping box 1, and a plurality of through grooves 301 are arranged on a bottom wall of the U-shaped frame 3. The plurality of placing mechanisms 4 are arranged on the upper side of the U-shaped frame 3 and correspond to the plurality of through grooves 301 respectively. The pre-drying mechanism 5 is installed on the U-shaped frame 3 and arranged on the upper side of the paint dipping, and is used for drying the motor rotor. The pair of lifting mechanisms 6 are symmetrically installed on both ends of the pre-drying mechanism 5, and the pair of lifting mechanisms 6 cooperate with each other and are used for lifting the placing mechanisms 4. The linkage ropes 7 are connected to the pair of placing mechanisms 4 respectively, and when one of the placing mechanisms 4 is lifted by the lifting mechanism 6, the adjacent placing mechanisms 4 can be tilted under the action of the linkage ropes 7, thereby being used for overturning the motor rotor.

[0042] First, the jacking cylinders 201 are controlled to be elongated, the U-shaped frame 3 and the placing mechanisms 4 are lifted by the jacking cylinders 201, and different models of the motor rotors in the paint dipping can be placed on the placing mechanisms 4, so as to improve the paint dipping efficiency of the motor rotor. The jacking cylinders 201 are controlled to be contracted, and the motor rotors on the placing mechanisms 4 are dipped in the paint dipping box 1.

[0043] During the paint dipping process of the motor rotor, the placing mechanisms 4 can be lifted regularly in sequence by the lifting mechanisms 6, and in the lifting process of the placing mechanisms 4, the adjacent placing mechanisms 4 can be tilted by pulling under the action of the linkage ropes 7, so as to overturn the motor rotors on the adjacent placing mechanisms 4, that is, Figure 8 the state shown. At the same time, in the lifting process of the placing mechanisms 4, the flowability of the paint dipping in the paint dipping box 1 can be also accelerated, so that the motor rotors on the adjacent placing mechanisms 4 can be better dipped, the paint dipping can be deeper into the middle part of the rotor coil, and the problems of insufficient and uneven paint dipping can be avoided.

[0044] When the placing mechanisms 4 are lifted above the paint dipping liquid level, the lifted motor rotors can be dried by the pre-drying mechanism 5, so as to realize the solidification of the surface or the middle part of the coil of the motor rotor, reduce the flowability of the paint dipping, and also heat the motor rotor, so that the motor rotor can keep a certain temperature when being dipped again, and has better paint dipping effect.

[0045] When the motor rotor is dried for a period of time, the placing mechanism 4 is lowered by the lifting mechanism 6, and the re-dipping is completed. The flowability of the dipping paint in the dipping tank 1 can be accelerated during the lowering of the placing mechanism 4. Then, the pre-drying mechanism 5 moves to the upper side of the adjacent placing mechanism 4, and the above operation is repeated. Such a cycle can complete the integrated operation of dipping, turning over and drying of the motor rotor on the placing mechanism 4, that is, the dipping and drying can be realized at the same time, the subsequent drying time is greatly shortened, the dipping efficiency is improved to a certain extent, and better dipping effect is also achieved.

[0046] As shown in Figures 1 to 10 , the U-shaped frame 3 is fixedly connected with a plurality of pairs of guide rods 302. Each pair of guide rods 302 is symmetrically arranged on both sides of the through groove 301 in a vertical state. The end of the guide rod 302 is connected with a limiting ring, and the diameter of the limiting ring is greater than the diameter of the guide rod 302. The guide rod 302 plays a role in guiding the lifting of the placing mechanism 4, as shown in Figure 2 and Figure 8 , so as to avoid displacement of the placing mechanism 4 on the upper side of the U-shaped frame 3.

[0047] Preferably, the length of the guide rod 302 is less than the height of the pre-drying mechanism 5 from the bottom wall of the U-shaped frame 3, so as to avoid collision between the placing mechanism 4 and the pre-drying mechanism 5 during lifting.

[0048] As shown in Figures 1 to 10 , the placing mechanism 4 includes a placing frame 401, a plurality of movable lining plates 403 and a plurality of baffles 405. The placing frame 401 is arranged on the inner side of the U-shaped frame 3. The movable lining plate 403 is slidably arranged on the placing frame 401, and a plurality of placing grooves 404 are arranged on the movable lining plate 403 and the placing frame 401. The baffle 405 covers the placing groove 404. By adjusting the position of the movable lining plate 403, different models of motor rotors can be placed in the corresponding pair of placing grooves 404, as shown in Figure 2 , so that a plurality of models of motor rotors can be dipped at one time, thereby improving the dipping efficiency of the motor rotor.

[0049] Preferably, the horizontal cross-sectional area of the placing frame 401 is greater than the area of the through groove 301, and the ears 402 are fixedly connected to both ends of the placing frame 401. The ears 402 are slidably arranged on the guide rods 302. When the placing frame 401 is placed at the bottom of the U-shaped frame 3, the dipping paint in the dipping tank 1 can contact the motor rotor on the placing mechanism 4 through the through groove 301, and then the dipping operation can be completed. By sliding the ears 402 on the guide rods 302, the placing mechanism 4 can be prevented from being displaced in the dipping tank 1, so as to ensure the subsequent pre-drying and turning over effect.

[0050] The ear plate 402 is provided with a through hole, the diameter of the through hole is greater than the diameter of the guide rod 302 and less than the diameter of the limiting ring. In this way, when one of the placing mechanisms 4 is lifted by the lifting mechanism 6, the adjacent placing mechanism 4 can be lifted to a certain height and tilted through the linkage rope 7, so as to realize the overturning of the motor rotor on the adjacent placing mechanism 4, so that the motor rotor can be better dipped in paint, as shown in Figure 8

By screwing the bolts into the adjusting holes 406, the movable backing plate 403 can be fixed, which is convenient to operate.

[0056] In addition, the pre-drying zone 503 is a combination of an electric heating wire and a metal rod, and the electric heating wire is wound around the metal rod. The electric heating wire can generate heat when it operates, and then the motor rotor on the lifted placing mechanism 4 can be pre-dried.

[0058] When the pre-drying area 503 pre-dries the motor rotor, the suction fan 504 also operates, and the suction fan 504 extracts heat from both sides of the mounting seat 502 through the three-way pipe, the branch pipe 505 and the suction pipe 506, and purifies the heat gas by using the purification box 507, so that the odor gas generated during the pre-drying of the motor rotor is not overflowed, and environmental pollution is avoided, and the overall environmental protection effect is improved.

[0059] The purification box 507 is provided with filter purification substances such as molecular sieve and activated carbon, which are used to filter and purify harmful substances in the hot gas.

[0060] In addition, in order to improve the utilization rate of heat energy resources, the purification box 507 is also connected with a recovery pipe, which can transport the filtered and purified hot gas to the subsequent drying end of the motor rotor, or to the preheating section of the motor rotor, so as to facilitate subsequent paint dipping operations.

[0063] Preferably, the servo motor 604 can be forward and reverse rotated, and has a self-locking function. When the placing mechanism 4 does not need to be lifted, the winding roller 603 can be fixed, so that the winding roller 603 does not release the hook 606.

[0064] In addition, the hook 606 is made of metal material, so that the hook 606 can pull the lifting rope 605 to be in a tight state in the paint, so as to clamp the lug plate 402.
