Description

Technical Field

[0001] This utility model relates to the field of high-efficiency epoxy insulating varnish coating technology for motor stator impregnation, specifically to a high-efficiency epoxy insulating varnish coating device for motor stator impregnation. Background Technology

[0002] The motor stator is one of the core components of a motor, and its performance directly affects the motor's operating efficiency and reliability. In order to enhance electrical insulation strength, resist the influence of external environmental factors, enhance mechanical strength, promote heat conduction, and prevent heat accumulation, the motor stator is coated with insulating varnish during the manufacturing process.

[0003] Currently, when coating motor stators with insulating varnish, the immersion method is commonly used. This involves using lifting tools to submerge the motor stators in the insulating varnish liquid, allowing them to absorb components from the liquid or react with it to achieve the coating process. However, this immersion method involves a small number of stators being immersed at a time, and after immersion, sufficient time is required for the varnish to dry to prevent waste. This results in poor processing continuity, making the immersion method inefficient and time-consuming. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency epoxy insulating varnish coating device for impregnating motor stators, in order to solve the problems mentioned in the background art. The common method for coating motor stators with insulating varnish involves immersion impregnation, where a hoisting tool is used to submerge the motor stator in the insulating varnish liquid, allowing it to absorb components from the liquid or react with it to achieve the coating process. However, this method results in a small number of stators being impregnated at a time, and after impregnation, sufficient time is required for the varnish to dry to prevent waste, leading to low processing efficiency and time consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency epoxy insulating varnish coating device for impregnating motor stators, comprising a coating box, with fixed vertical plates fixedly installed at the top of both sides of the coating box, bearings with seats symmetrically installed on the inner side of each fixed vertical plate, and a rotating shaft fixedly connected between the two bearings with seats. Placement components and positioning components are arranged in a circular array on the outer side of the rotating shaft. Slide rails are symmetrically installed on the inner walls of both sides of the front of the coating box, with a limit plate fixedly installed at the end of the slide rail away from the coating box. A support component is slidably connected inside the slide rail. By rotating the rotating shaft, the support plate, and the support rod, the steps of cyclic impregnation and waiting for the insulating varnish to dry can be completed simultaneously, improving impregnation efficiency and ensuring processing continuity. Through the designed baffle, positioning screw, guide rod, mounting groove, moving plate, positioning insert, and positioning hole, the position of the motor stator is limited during processing, ensuring stable completion of the impregnation process.

[0006] Preferably, the placement assembly includes a support plate, a support rod, a baffle, and a positioning rod. Multiple sets of support plates are fixedly arranged on the outer side of the rotating shaft. A baffle is fixedly arranged on one side of the support plates on both sides. A support rod penetrating the baffle is installed on one side of the support plate at one end of the rotating shaft. A positioning hole is opened at the end of the support rod. A positioning rod penetrating the baffle is installed on the side of the support plate at the other end of the rotating shaft. Support rods with baffles and positioning rods are arranged on both sides of the support plate in the middle, which facilitates the limiting of the motor stator to be impregnated and ensures the stability of the impregnation process.

[0007] Preferably, the positioning assembly includes a positioning screw, a guide rod, a mounting groove, a movable plate, and a positioning insertion hole. The other support plates on the same side as the support plate located at one end of the rotating shaft have mounting grooves. A movable plate is installed inside the mounting groove. A guide rod is installed between the support plates on both sides. A positioning screw is installed between the two guide rods. The positioning screw and guide rod pass through the movable plate and the support plate. The positioning screw is used to drive the movable plate closer to the positioning insertion rod to complete the positioning.

[0008] Preferably, the support assembly includes a sliding frame, a placement block, and a handle. The sliding frame is slidably connected inside the slide rail. Placement blocks are equidistantly arranged at the top of the sliding frame. A handle is fixedly provided on the front of the sliding frame for placing the motor stator after impregnation processing, providing a placement platform for disassembling and assembling the motor stator.

[0009] Preferably, a limit plate is fixedly provided at one end of the slide rail, and the other end of the slide rail is a solid rail, which facilitates the restriction of the movement of the sliding frame and prevents the sliding frame from falling off the slide rail.

[0010] Preferably, a support leg is fixedly provided at the diagonal corner of the bottom of the coating box, and an anti-slip pad is fixedly provided at the bottom of the support leg to improve the support stability.

[0011] Preferably, a drain pipe penetrating the bottom wall of the coating box is installed at the middle of the bottom end of the coating box, and a valve is installed in the middle of the drain pipe to facilitate the recycling of the used insulating varnish.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By designing multiple sets of seated bearings, rotating shafts, support plates, and support rods, multiple motor stators can be impregnated in a single operation. Furthermore, by rotating the rotating shaft, support plate, and support rod, the steps of cyclic impregnation and waiting for the insulating varnish to dry can be completed simultaneously, improving the efficiency of the impregnation process and ensuring its continuity. Through the design of baffles, positioning screws, guide rods, mounting grooves, moving plates, positioning inserts, and positioning holes, the position of the motor stators is limited during the impregnation process, ensuring the stable completion of the impregnation process.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-4This utility model provides a high-efficiency epoxy insulating varnish coating device for impregnating motor stators, including a coating box 1. Fixed vertical plates 3 are fixedly installed at the top of both sides of the coating box 1. Bearings 4 with seats are symmetrically installed on the inner sides of the fixed vertical plates 3. A rotating shaft 5 is fixedly connected between two bearings 4, allowing the rotating shaft 5 to rotate. Placement components and positioning components are arranged in a circular array on the outer side of the rotating shaft 5. The placement components include support plates 6, support rods 7, baffles 8, and positioning inserts 13. Multiple sets of support plates 6 are fixedly installed on the outer side of the rotating shaft 5. Baffles 8 are fixedly installed on one side of the support plates 6 on both sides. A support rod 7 penetrating the baffle 8 is installed on one side of the support plate 6 at one end of the rotating shaft 5. A positioning insert 14 is opened at the end of the support rod 7. A through-hole 14 is installed on the side of the support plate 6 at the other end of the rotating shaft 5. The positioning rod 13 of the baffle 8 is provided on both sides of the support plate 6 in the middle. The support rod 7 and the positioning rod 13 with the baffle 8 are provided. The positioning rod 13 can be inserted into the positioning hole 14, so that the positioning rod 13 and the support rod 7 form a complete support shaft. The positioning component includes a positioning screw 9, a guide rod 10, a mounting groove 11, a moving plate 12, and a positioning hole 14. The support plate 6 on the same side as the support plate 6 at one end of the rotating shaft 5 has a mounting groove 11. The moving plate 12 is provided inside the mounting groove 11. The guide rod 10 is provided between the support plates 6 on both sides. The positioning screw 9 is provided between the two guide rods 10. The positioning screw 9 and the guide rod 10 pass through the moving plate 12 and the support plate 6. The end of the positioning screw 9 away from the support plate 6 has a thread. The other end of the positioning screw 9 passes through the other support plate 6 and is fixedly connected to the moving plate 12.

[0021] When installing the motor stator, first place the motor stator on the support rod 7, then rotate the positioning screw 9. The positioning screw 9 rotates and engages with the support plate 6 located near the threaded end of the positioning screw 9. This causes the positioning screw 9 to push the moving plate 12 to slide along the guide rod 10 from the mounting groove 11, which in turn drives the positioning insert 13 and the baffle 8 to approach the corresponding support rod 7 and the other baffle 8. This allows the positioning insert 13 to be inserted into the positioning insertion hole 14 at the end of the support rod 7, forming a closed motor stator support structure.

[0022] The inner walls of both sides of the front of the coating box 1 are symmetrically equipped with slide rails 16. A limit plate 20 is fixedly installed at one end of the slide rail 16 away from the coating box 1. The other end of the slide rail 16 is a solid rail. Both ends restrict the position of the sliding frame 17 within the slide rail 16 to prevent the sliding frame 17 from detaching from the slide rail 16. A support assembly is slidably connected inside the slide rail 16. The support assembly includes the sliding frame 17, a placement block 18, and a handle 19. The top of the sliding frame 17 is provided with equidistant placement blocks 18 for supporting the motor stator. The front of the sliding frame 17 is fixedly provided with a handle 19 to provide a force point for pushing and pulling the sliding frame 17. The bottom of the coating box 1 is fixedly provided with support legs 2 at diagonal corners. The bottom of the support legs 2 is fixedly provided with anti-slip pads to enhance friction and improve support stability. The bottom of the coating box 1 is provided with a drain pipe 15 that penetrates the bottom wall of the coating box 1. The drain pipe 15 is provided with a valve in the middle of the pipe body to facilitate the recycling of the used insulating varnish.

[0023] Before installing the motor stator, first place the installed motor stator on the placement block 18. Then install the remaining motor stators on the support rod 7 at the top of the rotating shaft 5. Then pull the handle 19 to move the sliding frame 17 outward along the slide rail 16. The operator assists the rotating shaft 5 to rotate so that the support plate 6, support rod 7 and motor stator in the initial position rotate into the coating box 1. Then install the motor stators in sequence.

[0024] When this application embodiment is used:

[0025] When using this device, first rotate the rotating shaft 5 so that one set of support plates 6, support rods 7 and their parts are above the placement block 18. Place the motor stator onto the support rod 7. Then rotate the positioning screw 9. The positioning screw 9 rotates and engages with the support plate 6 near the threaded end of the positioning screw 9. This causes the positioning screw 9 to push the moving plate 12 to slide along the guide rod 10 from the mounting groove 11, moving the positioning insert 13 and the baffle 8 closer to the corresponding support rod 7 and the other baffle 8. The positioning insert 13 is then inserted into the positioning hole 14 at the end of the support rod 7, forming a closed motor stator support structure. At this point, the motor stator is in contact with the placement block 18 under the influence of gravity. Then pull the handle 19 to... The sliding frame 17 moves outward along the slide rail 16, and the operator assists in rotating the rotating shaft 5, causing the support plate 6, support rod 7, and motor stator in the initial position to rotate into the coating box 1. Another set of support plates 6, support rods 7, and their parts are now on the placement block 18. The motor stator is then installed in the same manner. During this process, as the impregnation of the motor stator proceeds, the motor stator, after being impregnated with insulating varnish, will detach from the insulating varnish liquid. Excess insulating varnish will flow downward and re-enter the coating box 1, reducing resource waste. At the same time, the motor stator installed below the rotating shaft 5 is also impregnated, allowing the impregnation and drying processes to occur simultaneously, which improves impregnation efficiency.

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.
