Description

Technical Field

[0001] This utility model belongs to the field of motor coil processing technology, and specifically relates to a motor coil impregnation device. Background Technology

[0002] The motor coil is the most vulnerable component in the motor structure. In order to improve the moisture and corrosion resistance and insulation strength of the motor coil, as well as improve its mechanical strength, thermal conductivity and heat dissipation effect and delay aging, the rewound motor coil must be impregnated with varnish.

[0003] Traditional motor coil impregnation devices suspend the motor coil on a hanger and use a drive device to lower the motor coil into the paint solution in the impregnation tank. However, the hanger is usually fixedly connected to its drive device. After the motor coil is impregnated, it takes a long time for the paint on the motor coil to cure, which affects the efficiency of motor coil impregnation and is not conducive to production use. Utility Model Content

[0004] The purpose of this invention is to provide a motor coil impregnation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An apparatus for impregnating motor coils, comprising:

[0007] The impregnation tank is configured as a box with an opening at the top. The impregnation tank is filled with impregnation liquid. An upper box is installed at the top of the impregnation tank via a connecting side plate. A driving component is installed inside the upper box. A rectangular frame is installed at the lower end of the driving component. Several sets of hooks are provided at the lower end of the rectangular frame for hooking motor coils, which facilitates the impregnation process of motor coils. The impregnation tank is also equipped with a drying mechanism, which can accelerate the curing speed of the impregnation liquid in the motor coils after impregnation, thereby improving the impregnation efficiency.

[0008] It also includes a pressing mechanism, which includes a pressing connector and a pressing plate. The pressing plate is provided at the lower end of the pressing connector and is located at the upper end of the rectangular frame. By moving the pressing plate downward and pressing down on the rectangular frame, the rectangular frame and the motor coil on the hook can be driven to extend into the interior of the impregnation tank for impregnation.

[0009] Preferably, the driving component and the rectangular frame are both configured in two sets and symmetrically arranged. By configuring them in two sets, it is beneficial that while one set is performing the impregnation process, the other set can perform the process of accelerating the curing speed of the paint. The two sets work alternately, improving the impregnation efficiency of the motor coil and facilitating mass production. The driving component includes a driving motor, a threaded rod, a threaded sleeve, and a connecting rod. The driving motor is installed inside the upper housing via a bracket. The output end of the driving motor is connected to the threaded rod, and the outer end of the threaded rod is threadedly connected to the threaded sleeve. The lower end of the threaded sleeve is connected to the connecting rod, and the lower end of the connecting rod is connected to the rectangular frame. Both sides of the bottom of the upper housing are provided with strip-shaped limiting grooves, which facilitate the sliding of the connecting rod inside the strip-shaped limiting grooves and provide a limiting function, thus facilitating the lateral movement of the connecting rod. After one set of rectangular frames has been impregnated, the driving motor is activated, which drives the threaded rod to rotate. This causes the threaded sleeve to move the connecting rod away from the driving motor, which helps the rectangular frame with the motor coil and the hook to move below the drying mechanism, thus accelerating the curing speed of the paint on the motor coil.

[0010] Preferably, the connecting rod includes an upper connecting rod, a connecting spring, and a lower connecting rod. The lower end of the threaded sleeve is connected to the upper connecting rod, and the upper end of the lower connecting rod is located inside the upper connecting rod. The lower connecting rod is slidably connected to the upper connecting rod. The connecting spring is installed inside the upper connecting rod, with one end of the connecting spring connected to the upper end of the lower connecting rod. The lower end of the lower connecting rod is connected to the rectangular frame. In the initial state, the elastic force of the connecting spring ensures that most of the upper end of the lower connecting rod is located inside the upper connecting rod, allowing the rectangular frame and hook to be positioned above the impregnation tank, facilitating their movement below the drying mechanism. During impregnation, the lower pressure plate slowly presses down on the rectangular frame, causing the upper end of the lower connecting rod to extend from inside the upper connecting rod, thereby moving the rectangular frame and hook downwards. This allows the motor coil to extend into the impregnation tank for the impregnation process. After impregnation, the lower pressure plate slowly moves upwards, and with the elastic force of the connecting spring, the rectangular frame and hook move upwards and reset, thus disengaging from the impregnation tank.

[0011] Preferably, the pressing connector includes a cylinder and a pressing rod. The cylinder is installed at the upper end of the upper housing, and the output end of the cylinder is connected to the pressing rod. The lower end of the pressing rod is connected to the upper end of the pressing plate. The pressing plate is located above the two sets of rectangular frames, which is beneficial for pressing down the rectangular frames simultaneously or pressing down one set at a time. In use, when impregnation is required, the cylinder is activated by an external controller, so that the output end of the cylinder drives the pressing plate to move down through the pressing rod. This causes the pressing plate to slowly press down the corresponding rectangular frame, thereby causing the rectangular frame to extend the hook with the motor coil installed into the impregnation tank for the impregnation process.

[0012] Preferably, the drying mechanism includes a drying chamber, a drying motor, a connecting pipe, and a drying plate. Drying chambers are installed inside both sides of the upper chamber. The drying motor is installed inside each drying chamber. The connecting pipe is connected to the bottom of the upper chamber. The lower end of the connecting pipe passes through the bottom of the upper chamber and connects to the drying plate. A connecting channel is opened inside the drying plate. Several sets of air outlets are opened at the bottom of the drying plate, and all sets of air outlets are connected to the connecting channel. The air outlets allow the air blown by the drying motor to pass through the connecting pipe and the connecting channel sequentially and flow out through the air outlets, blowing onto the motor coil after it has been impregnated with paint, which is beneficial for the paint to cure. Furthermore, having multiple sets of air outlets evenly distributed at the bottom of the drying plate makes the airflow more uniform and gentle, avoiding excessive flow velocity that could lead to uneven paint distribution on the motor coil.

[0013] Preferably, the drying chamber is further provided with a heating plate located below the drying motor. The heating plate has a heating source inside, which can heat the heating plate. The heating plate has several sets of through holes evenly distributed inside, which is conducive to uniform airflow. The through holes allow the drying motor to drive the airflow through the through holes and carry away the heat generated by the heating plate, so that the airflow has a certain temperature, thereby further improving the curing efficiency of the paint on the motor coil.

[0014] Preferably, cylinders 2 are provided on both sides of the upper end of the upper box. The output ends of cylinders 2 pass through the upper box and are connected to the upper end of the drying box. The connecting pipe is slidably connected to the bottom end of the upper box. During operation, the cylinders 2 can drive the drying box to move downward a certain distance, which in turn can drive the drying plate to move downward a certain distance, so that the drying plate is closer to the rectangular frame, which is beneficial to improving the curing efficiency of the paint.

[0015] Preferably, a collection plate is provided on both sides of the paint impregnation tank. The collection plate is located below the drying plate. A collection groove is provided at the upper end of the collection plate. A collection channel is provided inside the collection plate at the lower end of the collection groove. The collection groove is connected to the collection channel through several sets of through holes. An outflow hole is provided at the bottom of the side of the collection plate near the paint impregnation tank. This facilitates the paint dripping from the motor coil after impregnation to fall into the collection groove and then flow into the interior of the paint impregnation tank through the outflow hole, thereby realizing the function of paint recovery.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention features a pressing mechanism that moves a rectangular frame with hooks down into the paint-dipping tank, facilitating the paint-dipping process of the motor coil on the hooks. When the pressing mechanism moves upward, it resets the rectangular frame. One pressing plate can simultaneously move two sets of rectangular frames downward, or move them individually. A driving component moves the dipped rectangular frame towards the side of the upper chamber, facilitating its movement below the drying mechanism. This drying mechanism improves the curing speed of the paint on the motor coil after dipping, thereby increasing production efficiency and benefiting mass production. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please see Figures 1-6 As shown, a motor coil impregnation device includes:

[0031] The impregnation tank 10 is configured as a box with an opening at the top. The impregnation tank 10 is filled with impregnation liquid. The upper box 12 is installed at the top of the impregnation tank 10 through the connecting side plate 11. The upper box 12 is equipped with a driving component. A rectangular frame 25 is installed at the lower end of the driving component. Several sets of hooks 14 are provided at the lower end of the rectangular frame 25, which can be used to hook the motor coil, facilitating the motor coil impregnation process. The impregnation tank 10 is also equipped with a drying mechanism, which can accelerate the curing speed of the motor coil impregnation liquid, thereby improving the impregnation efficiency.

[0032] It also includes a pressing mechanism, which includes a pressing connector and a pressing plate 32. The lower end of the pressing connector is provided with a pressing plate 32, which is located at the upper end of the rectangular frame 25. By moving the pressing plate 32 downward and pressing down on the rectangular frame 25, the rectangular frame 25 and the motor coil on the hook 14 can be driven to extend into the interior of the impregnation tank 10 for impregnation.

[0033] refer to Figures 1-6As shown, both the driving component and the rectangular frame 25 are arranged in two sets symmetrically. This arrangement allows one set to perform the impregnation process while the other set accelerates the curing of the paint. The two sets work alternately, improving the impregnation efficiency of the motor coil and facilitating mass production. The driving component includes a drive motor 20, a threaded rod 21, a threaded sleeve 22, and a connecting rod. The drive motor 20 is mounted inside the upper housing 12 via a bracket. The output end of the drive motor 20 is connected to the threaded rod 21, and the outer end of the threaded rod 21 is threadedly connected to the threaded sleeve 22. The lower end of the threaded sleeve 22 is connected to the connecting rod. The lower end of the connecting rod is connected to the rectangular frame 25. Both sides of the bottom of the upper box 12 are provided with strip-shaped limiting grooves, which facilitates the sliding of the connecting rod inside the strip-shaped limiting grooves and can play a limiting role. It is also beneficial for the connecting rod to move laterally. After a set of rectangular frames 25 is dipped in paint, the drive motor 20 is started. The drive motor 20 drives the threaded rod 21 to rotate, which in turn causes the threaded sleeve 22 to drive the connecting rod to move away from the drive motor 20. This is beneficial for the rectangular frame 25 with the motor coil installed and the hook 14 to move below the drying mechanism, which helps to speed up the curing of the paint on the motor coil.

[0034] refer to Figures 1-6 As shown, the connecting rod includes an upper connecting rod 23, a connecting spring 231, and a lower connecting rod 24. The lower end of the threaded sleeve 22 is connected to the upper connecting rod 23, and the upper end of the lower connecting rod 24 is located inside the upper connecting rod 23. The lower connecting rod 24 and the upper connecting rod 23 are slidably connected. The upper connecting rod 23 is equipped with a connecting spring 231 inside, and one end of the connecting spring 231 is connected to the upper end of the lower connecting rod 24. The lower end of the lower connecting rod 24 is connected to the rectangular frame 25. In the initial state, the elastic force of the connecting spring 231 ensures that most of the upper end of the lower connecting rod 24 is located inside the upper connecting rod 23, thereby making the rectangular frame 25... The rectangular frame 25 and hook 14 can be located above the paint dipping tank 10, making it easy for the rectangular frame 25 and hook 14 to move below the drying mechanism. When the paint is dipped, the lower pressure plate 32 slowly presses down on the rectangular frame 25, causing the upper end of the lower connecting rod 24 to extend from the inside of the upper connecting rod 23, thereby driving the rectangular frame 25 and hook 14 to move down, making it easier for the motor coil to extend into the paint dipping tank 10 for the paint dipping process. After the paint dipping is completed, the lower pressure plate 32 slowly moves up, and with the elastic force of the connecting spring 231, it drives the rectangular frame 25 and hook 14 to move up and reset, that is, to disengage from the inside of the paint dipping tank 10.

[0035] refer to Figures 1-6As shown, the pressing connector includes a cylinder 30 and a pressing rod 31. The cylinder 30 is installed on the upper end of the upper housing 12. The output end of the cylinder 30 is connected to the pressing rod 31. The lower end of the pressing rod 31 is connected to the upper end of the pressing plate 32. The pressing plate 32 is located above the two sets of rectangular frames 25, which is beneficial to press down the rectangular frames 25 at the same time, or press down one set at a time. When in use, that is, when impregnation is required, the cylinder 30 is started by the external controller, so that the output end of the cylinder 30 drives the pressing plate 32 to move down through the pressing rod 31, so that the pressing plate 32 slowly presses down the corresponding rectangular frame 25, thereby causing the rectangular frame 25 to drive the hook 14 with the motor coil installed to extend out of the impregnation tank 10 for the impregnation process.

[0036] refer to Figures 1-6 As shown, the air-drying mechanism includes an air-drying chamber 41, an air-drying motor 42, a connecting pipe 44, and an air-drying plate 45. Air-drying chambers 41 are installed inside both sides of the upper chamber 12. An air-drying motor 42 is installed inside each air-drying chamber 41. A connecting pipe 44 is connected to the bottom of the upper chamber 12. The lower end of the connecting pipe 44 passes through the bottom of the upper chamber 12 and is connected to the air-drying plate 45. A connecting channel is opened inside the air-drying plate 45. Several sets of air outlets 46 are opened at the bottom of the air-drying plate 45, and all sets of air outlets 46 are connected to the connecting channel. The air outlets 46 allow the air blown by the air-drying motor 42 to pass sequentially through the connecting pipe 44 and the connecting channel, and then flow out through the air outlets 46, blowing onto the motor coil after it has been impregnated with paint. This facilitates the curing of the paint. Furthermore, the multiple sets of air outlets 46 evenly distributed at the bottom of the air-drying plate 45 ensure a more uniform and gentle airflow, preventing excessive flow velocity from causing uneven distribution of paint on the motor coil.

[0037] refer to Figures 1-6 As shown, a heating plate 43 is also provided inside the drying chamber 41. The heating plate 43 is located below the drying motor 42. A heating source is provided inside the heating plate 43 to heat the heating plate 43. Several sets of through holes are opened inside the heating plate 43. The sets of through holes are evenly distributed, which is conducive to the uniform flow of air. The through holes facilitate the air drying motor 42 to drive the airflow through the through holes and carry away the heat generated by the heating plate 43, so that the airflow has a certain temperature, thereby further improving the curing efficiency of the paint on the motor coil.

[0038] refer to Figures 1-6As shown, cylinders 40 are provided on both sides of the upper end of the upper box 12. The output ends of cylinders 40 pass through the upper box 12 and are connected to the upper end of the drying box 41. The connecting pipe 44 is slidably connected to the bottom end of the upper box 12. During operation, the cylinders 40 can drive the drying box 41 to move downward a certain distance, which in turn can drive the drying plate 45 to move downward a certain distance, so that the drying plate 45 is closer to the rectangular frame 25, which is beneficial to improving the curing efficiency of the paint.

[0039] refer to Figures 1-6 As shown, collection plates 15 are provided on both sides of the paint impregnation tank 10. The collection plates 15 are located below the drying plate 45. A collection trough 16 is provided at the upper end of the collection plate 15. A collection channel is provided inside the collection plate 15 at the lower end of the collection trough 16. The collection trough 16 is connected to the collection channel through several sets of through holes. An outflow hole is provided at the bottom end of the side of the collection plate 15 near the paint impregnation tank 10. This allows the paint dripping from the motor coil after impregnation to fall into the collection trough 16 and then flow into the interior of the paint impregnation tank 10 through the outflow hole, thus realizing the function of recovering the paint.

[0040] This invention utilizes a pressing mechanism to move the rectangular frame 25 with hooks 14 installed down into the impregnation tank 10, facilitating the impregnation process of the motor coil on the hooks 14. When the pressing mechanism moves upward, it allows the rectangular frame 25 to return to its original position. A set of pressing plates 32 can simultaneously move two sets of rectangular frames 25 downward, or move them downward individually. The driving component moves the impregnated rectangular frame 25 towards the side of the upper housing 12, facilitating its movement below the drying mechanism. This drying mechanism improves the curing speed of the impregnated motor coil's paint, thereby increasing production efficiency and benefiting mass production.
