[0002] The coil impregnation device used in the production of permanent magnet synchronous motors is a specialized piece of equipment for insulating and impregnating motor coils. It aims to improve the electrical insulation performance, mechanical strength, and environmental resistance of the coils, thereby ensuring the stability and service life of the motor.

[0003] Existing coil impregnation equipment for permanent magnet synchronous motor production typically consists of an impregnation tank, a coil fixing frame and lifting mechanism, and a varnish control system. The impregnation tank is made of corrosion-resistant material and is equipped with heating and stirring devices to ensure uniform varnish concentration and suitable temperature. The coil fixing and lifting mechanism can precisely position and control the coil immersion depth and time. The coil impregnation equipment can automatically adjust parameters such as temperature, time, and vacuum level to ensure process consistency.

[0004] Existing coil impregnation equipment for permanent magnet synchronous motor production typically uses fixed brackets to clamp the coils. Since the coils are in contact with the surface, the thickness of the impregnation paint on some coils may vary, thus affecting the quality of the impregnation. Utility Model Content

[0005] To overcome the problem that existing coil impregnation devices for permanent magnet synchronous motors typically use fixed brackets to clamp the coils, which may cause deviations in the thickness of the impregnation paint due to the contact between the coils and the surface, thus affecting the impregnation quality.

[0006] The technical solution of this utility model is as follows: a coil impregnation device for producing permanent magnet synchronous motors includes a paint tank and a cover plate. The cover plate is movably connected to the top of the paint tank. A first mounting bracket is fixedly provided at the bottom of the cover plate. Several slots are provided on the side wall of the first mounting bracket. A horizontal shaft is rotatably connected to the middle of each slot. A first gear is fixedly provided at the end of each horizontal shaft. A second mounting bracket is fixedly provided on the side wall of the first mounting bracket near the first gear. A toothed plate is movably connected to the inner bottom of the second mounting bracket. A servo motor is fixedly provided on the side wall of the second mounting bracket. A second gear is fixedly provided at the output end of the servo motor.

[0007] Furthermore, the first gears are linearly distributed and sequentially rotated on the top of the second mounting bracket. The first gears mesh with the gear plates, and the second gears mesh with the gear plates. A protective cover is fitted on the outer surface of the servo motor to improve the stability of the rotation of the first gears.

[0008] Furthermore, two cylinders are fixed to the top of the paint box, and the output ends of the cylinders are fixed to the surface of the cover plate in sequence. A sealing ring is snapped into the bottom of the cover plate, and an exhaust port is inserted into the top of the cover plate to improve the sealing performance of the cover plate.

[0009] Furthermore, the first mounting bracket and the second mounting bracket are fixedly connected to form an integrated structure, and a grid mesh is fixed at the bottom end of the first mounting bracket, which improves the installation performance during hoisting.

[0010] Furthermore, the two ends of the toothed plate pass through the second mounting bracket in sequence, and a limit block is fixed at both ends of the toothed plate.

[0011] Furthermore, several partitions are linearly fitted on the outer surface of the horizontal axis, which improves the stability of the coil rotation.

[0012] Furthermore, a heating tube is inserted into the bottom of the paint tank, and the heating tube is distributed in an S-shape. Two paddles are rotatably connected to the inner wall of the paint tank, and a temperature sensor is fixed on the inner wall of the paint tank to improve the paint dipping efficiency.

[0013] Furthermore, a drain port is inserted into the side wall of the paint tank and connects to the bottom of the paint tank. An inlet port is also inserted into the side wall of the paint tank, and valves are installed at the ends of both the drain port and the inlet port.

[0014] The beneficial effects of this utility model are:

[0015] Compared to traditional coil impregnation devices for permanent magnet synchronous motors, this device improves the stability of the horizontal shaft rotation through the cooperation of a first mounting bracket, slot, horizontal shaft, second mounting bracket, and first gear. The modular design of the horizontal shaft and first gear enhances coil installation efficiency. By starting the servo motor, the toothed plate can be moved horizontally at the inner bottom of the second mounting bracket. The cooperation between the toothed plate and the first gear can drive the horizontal shaft to rotate, thereby enabling fine-tuning of the coil rotation. This facilitates changing the coil support angle, improving the uniformity of coil impregnation and thus enhancing impregnation quality. Furthermore, the inclusion of limit blocks and partitions enhances the stability of the toothed plate's horizontal movement by supporting and limiting the movement, while the partitions isolate the coil, further improving the stability of coil impregnation.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Among the currently discovered feasible technologies, the following are described:

[0024] Please refer to Figures 1-5 The coil impregnation device for permanent magnet synchronous motor production includes a paint tank 1 and a cover plate 2. The cover plate 2 is movably connected to the top of the paint tank 1 and is used to seal the paint tank 1 to reduce the leakage of volatile gases. A first mounting bracket 4 is fixedly welded to the bottom of the cover plate 2. Several slots 5 are provided on the side wall of the first mounting bracket 4, each with a horizontal shaft 6 rotatably connected to the middle. The slots 5 pass through the top of the first mounting bracket 4 to facilitate the installation of the horizontal shaft 6. The surface of the horizontal shaft 6 can be fitted with a coil for support. The ends of the horizontal shaft 6 are all fixedly connected to a first gear 9 via a coupling. A second mounting bracket 8 is fixedly fixed to the side wall of the first mounting bracket 4 near the first gear 9. A toothed plate 10 is movably connected to the inner bottom of the second mounting bracket 8. A servo motor 12 is fixedly bolted to the side wall of the second mounting bracket 8. The servo motor 12 is an actuator motor used in automated control systems. The servo motor 12 realizes position control through feedback devices such as encoders. Precise control of speed and torque features rapid response, smooth operation, and high control accuracy. The servo motor 12 is existing technology and will not be described in detail here. The output end of the servo motor 12 is fixed with a second gear 11 via a coupling. The first gears 9 are linearly distributed and sequentially rotated and connected to the top of the second mounting bracket 8. The first gears 9 mesh with the gear plate 10, and the second gear 11 meshes with the gear plate 10. The external dimensions of the gear plate 10 and the first gear 9 are adapted to the internal dimensions of the second mounting bracket 8. A protective cover is fitted on the outer surface of the servo motor 12 to improve the stability of the rotation of the first gear 9. Starting the servo motor 12 can drive the gear plate 10 to move horizontally at the inner bottom of the second mounting bracket 8. Through the cooperation of the gear plate 10 and the first gear 9, the horizontal shaft 6 can be rotated, thereby driving the coil to rotate for fine adjustment. This facilitates changing the angle of the coil support, thereby improving the uniformity of the coil impregnation and thus improving the impregnation quality.

[0025] Two cylinders 3 are fixed to the top of the paint box 1 by bolts. The output ends of the cylinders 3 are fixed to the surface of the cover plate 2 by couplings. A sealing ring 21 is snapped into the bottom of the cover plate 2. The sealing ring 21 is made of rubber and is ring-shaped. An exhaust port 18 is inserted into the top of the cover plate 2. The exhaust port 18 passes through the cover plate 2 to release volatile gases. The other end of the exhaust port 18 can be connected to a burner to burn harmful gases. The burner is a device that mixes fuel and air in a certain proportion and ignites it to achieve a combustion reaction. The burner is existing technology and will not be described in detail here. This improves the sealing performance of the cover plate 2.

[0026] The first mounting bracket 4 and the second mounting bracket 8 are fixedly connected to form an integral structure. The bottom end of the first mounting bracket 4 is fixedly provided with a grid mesh 17, which improves the installation performance of the hoisting. The two ends of the toothed plate 10 pass through the second mounting bracket 8 in sequence. Both ends of the toothed plate 10 are fixedly provided with limit blocks 19, which improves the stability of the horizontal movement of the toothed plate 10. The outer surface of the horizontal shaft 6 is linearly sleeved with several partitions 20 to isolate the coil, thereby avoiding the coil collision during rotation and improving the stability of the coil rotation.

[0027] A heating tube 7 is inserted into the bottom of the paint tank 1. The heating tube 7 is distributed in an S-shape. Two paddles 16 are rotatably connected to the inner side wall of the paint tank 1. A temperature sensor 15 is fixed on the inner side wall of the paint tank 1 to improve the paint impregnation efficiency. A discharge port 13 is inserted into the side wall of the paint tank 1 and communicates with the bottom of the paint tank 1. An inlet 14 is inserted into the side wall of the paint tank 1. Valves are installed at the ends of the discharge port 13 and the inlet 14.

[0028] When using the coil impregnation device produced by this permanent magnet synchronous motor, the operator first moves the device to the designated position, then connects the external power supply. After the coil is sequentially sleeved on the outer surface of the horizontal shaft 6, the horizontal shaft 6 and the first gear 9 are sequentially engaged in the slot 5 and the interior of the second mounting bracket 8. Then, the cylinder 3 is started to drive the cover plate 2 to move vertically downward to close the paint tank 1, thereby immersing the first mounting bracket 4 and the coil in the paint. The horizontal shaft 6 is then started to heat the paint to increase molecular activity, and the paddle 16 is started to rotate to improve the fluidity of the paint. When the coil engagement affects the impregnation quality, the operator can start the servo motor 12. The servo motor 12 can drive the toothed plate 10 to move horizontally at the bottom of the inner side of the second mounting bracket 8. Through the cooperation of the toothed plate 10 and the first gear 9, the horizontal shaft 6 can be rotated, thereby driving the coil to rotate for fine adjustment. This facilitates changing the angle of the coil support, thereby improving the uniformity of the coil impregnation and thus improving the impregnation quality.

[0029] Considering that collisions may occur when the coil rotates, several partitions 20 are evenly fitted on the outer surface of the horizontal shaft 6 to isolate and limit the movement, thereby improving the stability of the coil's varnish-impregnated rotation.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
