[0020] In the present embodiment: the mounting shell 1 is the outer shell of the entire paint dipping equipment, which is used to provide a connection carrier for each internal part. The rotating base 12 located at the bottom of the inner cavity of the mounting shell 1 is used to provide a connection carrier for the connecting steel plate 2 and the elastic arc plate 21.

The elastic arc plate 21 is extruded on one side of the paint immersion chamber, and when the outer side of the elastic arc plate 21 is extruded, the elastic arc plate 21 bends toward the inner side of the entire paint immersion chamber, and the mounting rod 51 located at the top of the inner cavity of the mounting shell 1 is used to provide a carrier for the connection of the connecting frame 5, and the connecting frame 5 is used to provide a carrier for the connection of the counterweight connecting column 4. At this time, the connecting frame 5 and the mounting rod 51 cooperate with each other to form a connecting piece for installing the counterweight connecting column 4 and the connecting rod 41. When the elastic arc plate 21 is bent and deformed toward the entire paint immersion chamber, it can cause extrusion on the end of the counterweight connecting column 4 located on the inside, and when the end of the counterweight connecting column 4 is extruded, the inclination angle of the support rod assembly formed by the counterweight connecting column 4 and the connecting rod 41 changes.

When the end position of the connecting rod 41 changes, the knocking rope 42 located at the bottom of the connecting rod 41 moves synchronously with the connecting rod 41 in the immersion liquid, and drives the flow inside the immersion liquid. In the process of the stator winding being immersed in paint by the entire immersion equipment, the rotating base 12 drives the elastic arc plate 21 and the connecting steel plate 2 to rotate synchronously by rotation, and in the process of the connecting steel plate 2 and the elastic arc plate 21 rotating, when the connecting steel plate 2 rotates to one side of the extrusion rod 31, the extrusion rod 31 moves into the inner compartment of the connecting frame 3 under the obstruction of the connecting steel plate 2, and when the extrusion rod 31 moves to one side of the elastic arc plate 21, the resistance on the outside of the extrusion rod 31 When the elastic arc plate 21 is bent and deformed, it can squeeze one end of the counterweight connecting column 4, forcing one end of the counterweight connecting column 4 to flip downward.

The knocking rope 42 completes the striking of the inside of the paint dipping liquid during the repeated pulling and dropping process, and by striking the inside of the paint dipping liquid, the liquid inside the paint dipping liquid is promoted to flow, and at the same time, it can help to discharge the bubbles in the stator winding during the immersion process, and by driving the rotation of the entire paint dipping tank through the rotating base 12, it can help to assist the stator winding to better contact with the paint liquid during the paint dipping process, and the knocking rope 42 plays a role in amplifying the dynamics formed by the squeezing rod 31 on the elastic arc plate 21 in the entire paint dipping equipment, and assists the dynamics formed by the paint dipping tank during the rotation process to better act on the internal liquid flow of the paint dipping liquid.
[0021] A return spring 32 is fixedly connected to the inside of the connecting frame 3, and the other end of the return spring 32 is fixedly connected to the bottom of the extrusion rod 31; wherein the return spring 32 is used to reset the extrusion rod 31, and when the outer side of the extrusion rod 31 loses the pressing force of the connecting steel plate 2, the extrusion rod 31 is ejected to the outside by the deformation elastic force of the return spring 32, and at the same time, an extrusion force is applied to the elastic arc plate 21 moved to the outside of the extrusion rod 31, thereby causing the elastic arc plate 21 to deform. In addition, the elastic force coefficient of the return spring 32 is greater than the elastic force coefficient of the elastic arc plate 21.
[0022] A first guide cut surface 22 is cut on one side of the connecting steel plate 2, and a second guide cut surface 311 is cut on one side of the extrusion rod 31; wherein the first guide cut surface 22 and the second guide cut surface 311 both play a guiding role.
[0023] A CR rubber connecting wall 211 is provided on the inner side of the elastic arc plate 21, and the two ends of the CR rubber connecting wall 211 are fixedly connected to the connecting steel plates 2 on both sides; wherein the CR rubber connecting wall 211 is used to assist in forming a sealed connecting surface between a plurality of elastic arc plates 21 and a plurality of connecting steel plates 2.
[0024] A plurality of weight balls 43 are fixedly connected to the lower end of the knocking rope 42; the weight balls 43 act as a counterweight at the lower end of the knocking rope 42, and are also used to increase the undulation of the lower end of the knocking rope 42, so that the lower end of the knocking rope 42 forms an uneven surface, which helps to expand the flow amplitude formed inside the paint liquid.

At the same time, in the process of the extrusion rod 31 moving outward, one side of the elastic arc plate 21 is squeezed, and the elastic arc plate 21 is bent and deformed inwardly. When the elastic arc plate 21 is bent and deformed, one end of the counterweight connecting column 4 can be squeezed, forcing one end of the counterweight connecting column 4 to When the connecting rod 41 is rotated downward and one end of the counterweight connecting column 4 is rotated downward, one end of the connecting rod 41 is rotated upward, and in the process of the outer end of the connecting rod 41 being rotated upward, the knocking rope 42 is driven by the end of the connecting rod 41 to do an upward pulling action. When the squeezing rod 31 on one side of the elastic arc plate 21 leaves, the elastic arc plate 21 is reset at this time, and drives the counterweight connecting column 4 and the connecting rod 41 to reset. After the connecting rod 41 is reset, the knocking rope 42 moves downward again and is immersed in the paint dipping liquid. During the rotation of the rotating base 12, several squeezing rods 31 cooperate with each other to repeatedly squeeze several elastic arc plates 21, causing several knocking ropes 42 to be repeatedly pulled up and dropped in the paint dipping liquid, so that the knocking rope 42 completes the striking of the inside of the paint dipping liquid during the repeated pulling and falling process, and promotes the flow of liquid inside the paint dipping liquid by striking the inside of the paint dipping liquid, and at the same time can help to discharge bubbles in the stator winding during the immersion process.
