[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Example:

[0025] Reference Figure 1-Figure 4 A motor coil tinning device comprises a working box 1 with an open end at the top, tin liquid can be injected into the working box 1 through the open end, a mounting box 2 is fixedly connected to the side wall of the working box 1, a reciprocating screw rod 201 is rotatably connected in the mounting box 2, and an extension plate 202 is threadedly connected to the reciprocating screw rod 201, and the extension plate 202 is in contact with the inner wall of the mounting box 2, and then a support plate 3 is fixedly connected to the extension plate 202.

[0026] When the reciprocating screw 201 rotates, the extension plate 202 can be reciprocated in the installation box 2, and the reciprocating screw 201 can be driven to rotate by a driving motor or a hydraulic motor, thereby causing the support plate 3 to reciprocate above the opening end of the working box 1.

[0027] An electric telescopic rod 4 is also fixedly connected to the support plate 3, and a movable plate 5 is fixedly installed at the output end of the electric telescopic rod 4 through a connecting shaft 401. By driving the switch of the electric telescopic rod 4, the connecting shaft 401 can drive the movable plate 5 to move up and down. When the movable plate 5 moves downward, it will enter the working box 1 through the opening end.

[0028] In addition, a driving machine 601 is fixedly connected to the movable plate 5, and a driving gear 6 is also fixedly connected to the output end of the driving machine 601, and the driving gear 6 is an incomplete gear. A connecting seat 501 is fixedly connected to the bottom of the movable plate 5, and a limiting rod 901 is rotatably connected to the connecting seat 501, and the limiting rod 901 and the swing gear 7 are on the same axis, and the placing plate 9 is fixedly connected to the limiting rod 901 through the mounting plate.

[0029] A swing gear 7 is arranged on the mounting plate on the placement plate 9, and the swing gear 7 is also an incomplete gear, and the driving gear 6 is meshed with the swing gear 7, and the swing gear 7 is connected to the movable plate 5 through a spring 8, and the spring 8 can use a double hook spring 8.

[0030] The connection method is that a first connecting rod 701 is fixedly connected to the swing gear 7, a second connecting rod 502 is fixedly connected to the movable plate 5, and then the hook parts at both ends of the spring 8 are respectively connected to the first connecting rod 701 and the second connecting rod 502, but the spring 8 is not fixedly welded to the first connecting rod 701 and the second connecting rod 502.

[0031] Here, when the motor coil needs to be tinned, the motor coil can be placed on the placement plate 9 and fixed. At this time, the reciprocating screw 201 is rotated, and the extension plate 202 is reciprocated on the installation box 2, and then the support plate 3 is driven to move back and forth above the opening end of the working box 1. At this time, the switch of the electric telescopic rod 4 is started to drive the movable plate 5 to move toward the working box 1. After that, the placement plate 9 is immersed in the tin liquid and the switch of the electric telescopic rod 4 is turned off. At this time, the tin liquid will tin the motor coil on the placement plate 9.

[0032] Then, refer to Figure 2 and Figure 3 As shown in , the driving machine 601 on the movable plate 5 is started again, so that the driving machine 601 drives the driving gear 6 to rotate clockwise, and at this time the driving gear 6 will drive the swing gear 7 to rotate counterclockwise, and both the driving gear 6 and the swing gear 7 are incomplete gears. When the driving gear 6 rotates clockwise, the meshing swing gear 7 will rotate counterclockwise. During this process, the position of the spring 8 is changed, and the spring 8 is stretched, so that the swing gear 7 drives the placement plate 9 to swing counterclockwise. At this time, the placement plate 9 will drive the motor coil to swing in the tin liquid for the first time, stirring the static tin liquid, thereby improving the uniformity of the tin liquid covering the surface of the motor coil, so that the tin liquid forms a uniform coating on the coil, improving the appearance quality of the coil, preventing unevenness in the coil gap, and improving the performance of the motor coil.

[0033] When the gear on the driving gear 6 is not meshed with the swing gear 7, the stretched spring 8 will drive the swing gear 7 to reset. At this time, the swing gear 7 drives the placement plate 9 to reset and swing clockwise, so that the motor coil can swing again in the tin liquid to improve the uniformity of the tin liquid covering the surface of the motor coil.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
