[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figures 1 to 4 The present invention provides a technical solution: a paint dipping device for a motor stator coil, comprising a paint liquid tank 1, step plates 2 are respectively provided on both sides of the paint liquid tank 1, slide rails 3 are provided on the outer sides of the step plates 2, guide frames 4 are provided on the slide rails 3, and hook frames 5 are provided between the guide frames 4 on the two sets of slide rails 3, the guide frames 4 can be driven by the slide rails 3 to slide freely, guide rods 41 are provided in the guide frames 4, rollers 51 are provided on the hook frames 5, and the rollers 51 are located above the step plates 2, and the hook frames 5 are moved under the action of the step plates 2. It can move up and down along the guide rod 41, the step plate 2 is provided with a magnet 21, and the hook frame 5 is provided with a magnet 52. The magnet 52 can be attracted by the magnet 21 and move along the hook frame 5. When the magnet 52 moves, it can drive the hook 54 on the hook frame 5 to rotate. Through the action of the step plate 2, when the hook frame 5 moves along the slide rail 3, the hook frame 5 can be driven to move up and down, so that the coil is no longer in a fixed state in the paint liquid box, which can facilitate the dissipation of air in the gap in the coil and allow the paint liquid to fully immerse in the coil.

[0027] In this embodiment, the step plate 2 is divided into a plate 1 22 and a plate 2 23. The ends of the plates 1 22 and 23 are both provided with a discharge slope 24, and the plates 1 22 and 23 are both provided with a triangular step 25. The discharge slope 24 is located at the end of the step plate 2. Since the discharge slope is inclined upward, after the immersion is completed, as the slide rail 3 drives the hook frame 5 to move slowly, the coil can be driven to be slowly lifted from the paint liquid tank 1, so that the coil can be easily removed.

[0028] In this embodiment, the magnet 21 is located at the top sharp corner of the triangular step 25. The magnet 21 is arranged at intervals on the triangular steps 25 of plate 1 22 and plate 23. Since it is separated on plate 1 22 and plate 23 and arranged at intervals, the magnet 21 will attract the magnet 52 to move alternately to the left and right, thereby enabling the hook 54 to continuously rotate left and right, changing the contact position of the hook 54 and the coil.

[0029] In this embodiment, the guide frame 4 is a hollow rectangular frame, and the inner sides of the two vertical plates of the guide frame 4 are provided with a clamping block 42. The end of the hook frame 5 is provided with a clamping groove 53. The hook frame 5 is clamped on the clamping block 42 through the clamping groove 53. The combination of the clamping block 42 and the clamping groove 53 can ensure that the hook frame 5 is always in a horizontal state to prevent it from getting stuck when moving up and down.

[0030] In this embodiment, a cylinder 45 is provided on the side of the guide frame 4, and the output shaft of the cylinder 45 is connected to the hook frame 5. When loading, the hook frame 5 is pulled to the highest point by the cylinder 45, so that the coil can be placed on the hook 54 conveniently.

[0031] In this embodiment, two upper and lower fixed edges 55 are provided on the side adjacent to the magnet 52 and the hook frame 5, and an extrusion strip 56 is provided between the two fixed edges 55. The fixed edge 55 can help the magnet 52 to be stuck on the hook frame 5. The extrusion strip 56 is made of rubber to increase friction.

[0032] In this embodiment, the top of the hook 54 is rotatably installed in the adjustment seat 57, and the adjustment seat 57 is fixedly installed on the hook frame 5. The hook 54 and the adjustment seat 57 are rotatably connected, and by replacing different adjustment seats 57, the installation needs of hooks of different sizes can be met.

[0033] In this embodiment, the inner side surface of the extrusion strip 56 is in close contact with the upper end of the hook 54, and the friction force caused by the extrusion can drive the hook 54 to rotate when the extrusion strip 56 moves left and right.

[0034] Working principle: When in use, the hook frame 5 is pulled to the highest point through the cylinder 45, the coil is hung on the hook 54, and then the slide rail 3 is started to drive the hook frame 5 to move toward the paint liquid tank 1. During the movement, the contact between the roller 51 on the hook frame 5 and the step plate 2 will make the hook frame 5 move up and down according to the shape of the triangular step 25 on the step plate 2, so that the coil can move up and down in the paint liquid tank 1. At the same time, due to the arrangement of the magnet 21, the magnet 52 and the magnet 21 are attracted to each other, so that the magnet 52 moves toward the magnet 21. During the movement, the hook 54 will be driven to rotate through the extrusion bar 56, so that the coil rotates continuously in the paint liquid, so that the paint liquid is more fully filled in the coil.

[0035] Based on the above, the hook frame and the step plate provided in the present invention cooperate with each other, and the coil moves up and down as the coil moves forward continuously, so that the air in the coil can be easily released from the viscous paint liquid during the continuous movement.

[0036] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
