Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0035] See Figures 1 to 6 , the utility model provides a technical solution:

[0036] A paint dipping device for stator coils, comprising a paint dipping tank 1, a paint dipping assembly 2 provided on one side of the paint dipping tank 1, a stirring assembly 3 provided on one side of the paint dipping tank 1, a circulation assembly 4 provided on one side of the paint dipping tank 1, a drying assembly 5 provided on one side of the paint dipping assembly 2, and a collection assembly 6 provided on one side of the paint dipping assembly 2;

[0037] The paint dipping assembly 2 includes an extension plate 201, a mobile frame 202, a mobile block 203, a cylinder 204, a hydraulic rod 205, a clamping bin 206, a clamping screw 207, a first motor 208 and a threaded rod 209. The extension plate 201 is fixedly connected to one side of the paint dipping bin 1, the mobile frame 202 is fixedly connected between the paint dipping bin 1 and the extension plate 201, the mobile block 203 is slidably connected to the inside of the mobile frame 202, the cylinder 204 is fixedly connected to the inside of the mobile block 203, the hydraulic rod 205 is arranged inside the cylinder 204, the clamping bin 206 is fixedly connected to the bottom of the hydraulic rod 205, and the first motor 208 is fixedly connected to the bottom of the hydraulic rod 209. A motor 208 is provided on one side of the mobile frame 202, and a threaded rod 209 is fixedly connected to the output end of the first motor 208 and is threadedly connected to the inside of the moving block 203. When in use, the stator coil to be dipped in paint is first clamped and fixed in the inside of the clamping bin 206 by rotating the clamping screw 207, and then the first motor 208 is started to drive the threaded rod 209 to rotate, driving the moving block 203 to slide inside the mobile frame 202 to the top of the paint dipping bin 1, and then the hydraulic rod 205 is started to drive the clamping bin 206 to move downward so that the fixed stator coil enters the inside of the paint dipping bin 1 for the paint dipping operation.

[0038] Considering that the effect of the paint will be reduced if it is left stationary for a long time, the stirring assembly 3 includes a partition 301, a connecting groove 302, a second motor 303, a rotating rod 304 and a stirring rod 305. The partition 301 is fixedly connected to the interior of the paint immersion tank 1 and divides the inner cavity of the paint immersion tank 1 into an upper and lower space. The connecting groove 302 is opened on one side of the partition 301, and the connecting groove 302 runs through the upper and lower sides of the partition 301. The second motor 303 is arranged on the outside of the paint immersion tank 1, and the rotating rod 304 is fixedly connected to the output end of the second motor 303 and is rotatably connected to the interior of the paint immersion tank 1. Multiple stirring rods 305 are fixedly connected to the surrounding side of the rotating rod 304. The paint liquid above the partition 301 of the paint immersion tank 1 can enter the bottom of the partition 301 of the paint immersion tank 1 through the connecting groove 302. Starting the second motor 303 drives the rotating rod 304 to rotate, and drives the stirring rod 305 to rotate to stir the paint liquid, so that the paint liquid remains active.

[0039] Taking into account that the paint cannot circulate in the upper and lower halves of the paint immersion tank 1, the circulation component 4 includes a water pump 401, a paint extraction pipe 402 and a paint outlet pipe 403. The water pump 401 is arranged on one side of the paint immersion tank 1, one end of the paint extraction pipe 402 is arranged at the input end of the water pump 401 and the other end is connected to the space below the partition 301 in the paint immersion tank 1, and the paint outlet pipe 403 is arranged at the output end of the water pump 401 and the other end is connected to the space above the partition 301 in the paint immersion tank 1. Starting the water pump 401 to circulate the paint liquid below the partition 301 of the paint immersion tank 1 to the top of the partition 301 of the paint immersion tank 1 for recycling can prevent the paint liquid from solidifying, resulting in a decrease in the quality of the paint immersion.

[0040] Taking into account the problem that foreign matter may adhere to the paint surface during drying if the paint is not dried in time after dipping, the drying component 5 includes a storage tank 501, a filter screen 502, a drying chamber 503 and a drying heating plate 504. The storage tank 501 is opened on one side of the extension plate 201, the filter screen 502 is arranged on the top of the storage tank 501, the drying chamber 503 is fixedly connected to the top of the filter screen 502, and multiple drying heating plates 504 are arranged inside the drying chamber 503 and electrically connected to an external power supply. When in use, the stator coil after paint dipping is moved to the top of the drying chamber 503, and then the hydraulic rod 205 is started again to drive the stator coil to move down between the multiple drying heating plates 504, and the drying heating plates 504 are started, so as to quickly dry the stator coil after paint dipping.

[0041] Furthermore, the collecting component 6 has the function of collecting the paint liquid dripping from the stator coil, such as Figure 4 As shown, the collecting assembly 6 includes a collecting hopper 601 and a collecting barrel 602. The collecting hopper 601 is arranged at the bottom of the receiving groove 501, and the collecting barrel 602 is arranged below the collecting hopper 601. When in use, the dripping paint liquid will fall into the inside of the collecting hopper 601 and be collected by the collecting barrel 602.

[0042] Furthermore, in order to prevent impurities above the partition 301 from entering the space below the partition 301 through the connecting groove 302, a filter screen 7 for filtering impurities is provided in the connecting groove 302, and the impurities are trapped above the filter screen 7 so as to clean the impurities. A filter screen 7 for filtering impurities is provided inside the connecting groove 302. The material of the filter screen 7 is stainless steel. When in use, the filter screen 7 is used to filter impurities inside the paint immersion tank 1.

[0043] Taking into account the poor stability of the clamping bin 206, two stabilizing plates 8 are fixedly connected to the top of the clamping bin 206, and two stabilizing grooves 9 are opened on one side of the moving block 203. The stabilizing grooves 9 are used to cooperate with the stabilizing plates 8 for sliding connection. When the clamping bin 206 is lifted or lowered during use, it can drive the stabilizing plates 8 to slide inside the stabilizing grooves 9, thereby improving the lifting stability of the clamping bin 206.

[0044] Specifically, when the stator coil dipping device is in use: first, the stator coil to be dipped in paint is clamped and fixed inside the clamping bin 206 by rotating the clamping screw 207, then the first motor 208 is started to drive the threaded rod 209 to rotate, driving the moving block 203 to slide inside the moving frame 202 to the top of the dipping bin 1, then the hydraulic rod 205 is started to drive the clamping bin 206 to move downward so that the fixed stator coil enters the interior of the dipping bin 1 for dipping in paint, and the paint liquid above the partition 301 of the dipping bin 1 can enter the bottom of the partition 301 of the dipping bin 1 through the connecting groove 302, and the second motor 303 is started to drive the rotating rod 304 Rotate, drive the stirring rod 305 to rotate and stir the paint liquid to keep the paint liquid active, and at the same time start the water pump 401 to circulate the paint liquid below the partition 301 of the paint immersion tank 1 to the top of the partition 301 of the paint immersion tank 1 for recycling, which can prevent the paint liquid from solidifying and causing the quality of the paint immersion to deteriorate. Move the stator coil after the paint immersion to the top of the drying chamber 503, and then start the hydraulic rod 205 again to drive the stator coil to move down between multiple drying heating plates 504, and start the drying heating plates 504, so as to quickly dry the stator coil after the paint immersion, and the dripping paint will fall into the inside of the collecting bucket 601 and be collected by the collecting barrel 602.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
