[0049] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings.

[0050] It should be noted that the technical terms or scientific terms used in the one or more embodiments of the present disclosure should be understood as the general meaning understood by the person skilled in the art to which the present disclosure belongs, unless otherwise defined. The terms "first", "second", and the like used in the one or more embodiments of the present disclosure do not represent any order, number, or importance, but are only used to distinguish different components.

The terms "up", "down", "left", "right", and the like are only used to represent relative positional relationships, and when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0051] To facilitate the understanding of the paint removal device provided by the embodiments of the present application, the application scenarios thereof are first described. The paint removal device provided by the embodiments of the present application can be applied to paint removal of flat copper wires, and in particular, can be applied to paint removal at the rounded edges of flat copper wires.

[0052] With the development of motor technology, the technology of flat copper wire motors is becoming mature. The most important feature of flat copper wire motors is that flat copper wires are used as coil conductors. Flat copper wire motors have the advantages of good heat dissipation performance, high power density, and good electromagnetic performance.

[0053] In the production process of flat copper wire motors, the copper retention rate of flat copper wires after paint removal has an important influence on the performance of flat copper wire motors. The higher the copper retention rate during paint removal, the better the electrical performance of the flat copper wire, and at the same time, material waste can be reduced.

[0054] The paint removal technology in the prior art usually removes the paint on the four surfaces of the flat copper wire by punching. In the punching process, in order to obtain a higher copper retention rate, it is necessary to set a smaller punching depth, which will make it difficult to remove the paint at the rounded edges of the flat copper wire.

[0055] The present application provides a paint removal device applied to paint removal of flat copper wires, which aims to remove the paint at the rounded edges of the flat copper wire while ensuring a high copper retention rate. The flat copper wire paint removal device in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0056] Reference is made to Figure 1 and Figure 2 , Figure 1 The present application provides a paint removal device applied to paint removal of flat copper wires, which aims to remove the paint at the rounded edges of the flat copper wire while ensuring a high copper retention rate. The flat copper wire paint removal device in the embodiments of the present application will be described in detail below with reference to the accompanying drawings. Figure 2This is a schematic diagram of milling with a milling cutter in an embodiment of this application. The paint removal device provided in this embodiment includes a machine base 1, which can be used to support the flat copper wire 5, as well as other components that can support the paint removal device. Specifically, the machine base 1 can be assembled from a combination of various materials such as cast iron, profiles, and plates, and can be equipped with corresponding fixing structures, limiting structures, etc., according to the various components and devices set on the machine base 1.

[0057] The flat copper wire 5 can be conveyed to the machine base 1 by a feeding device, which can be part of the paint removal device or a separate component. Specifically, the feeding device can be located on one side of the machine base 1. The feeding device can simultaneously convey and guide the flat copper wire 5. As an example, the feeding device may include a guide rail and a robot arm, wherein the guide rail is used to accommodate the flat copper wire 5, and the robot arm can reciprocate along the length of the guide rail and clamp the flat copper wire 5 to achieve the conveying of the flat copper wire 5.

[0058] The paint removal device also includes two opposing milling cutters 4. These two milling cutters 4 are spaced apart along a first direction, forming a channel between them to accommodate the flat copper wire 5. This first direction is perpendicular to the length direction in which the flat copper wire 5 extends. Each milling cutter 4 can rotate along its own axis, and when both milling cutters 4 rotate, they can mill the flat copper wire 5 within the channel.

[0059] like Figure 2 As shown, the flat copper wire 5 has four rounded corner edges 51. Along the first direction, the four rounded corner edges 51 are evenly distributed on opposite sides of the flat copper wire 5, that is, each side of the flat copper wire 5 along the first direction has two rounded corner edges 51. Each milling cutter 4 is used to mill the paint on the two rounded corner edges 51 on the side corresponding to the milling cutter 4.

[0060] For the coating on the four sides of the flat copper wire 5, excluding the four rounded corner edges 51, it can be completed either before or after removing the coating from the rounded corner edges 51. See also... Figure 3 as well as Figure 4 , Figure 3 This is a diagram illustrating traditional paint removal methods. Figure 4 A schematic diagram of the paint removal device provided in this application.

[0061] refer to Figure 3 In the traditional paint removal process, while removing the paint from the four sides, the paint at the rounded corner edge 51 is also removed by increasing the processing depth. Under this removal method, for a rounded corner edge 51, the punching amount when removing the paint from its two adjacent sides must be greater than or equal to half the radius of the rounded corner edge 51 on at least one side in order to ensure that the paint at the rounded corner edge 51 can be completely removed.

[0062] As shown in the paint removing process Figure 4 , the paint on the four corners 51 edges can be removed separately by using the paint removing device provided in the embodiments of the present application, and the size of the corner 51 does not need to be considered when removing the side paint, so that the processing depth when removing the side paint of the flat copper wire 5 can be reduced, thereby achieving clean paint removal at the corner 51 of the flat copper wire 5 while obtaining a larger copper retention rate.

[0063] The paint removing device provided in the embodiments of the present application further comprises a driving device 2 and a feeding device 3. The driving device 2 is used to drive the two milling cutters 4 to rotate, specifically to drive the two milling cutters 4 to rotate around their own axes respectively, so that the paint at the corner 51 can be milled. The feeding device 3 is used to drive the two milling cutters 4 to move in the feeding motion during milling. The feeding motion herein refers to the movement of the two milling cutters 4 moving towards each other along the first direction to interfere with the corner 51 of the flat copper wire 5, and then the paint at the corner 51 of the flat copper wire 5 is milled.

[0064] As an optional implementation, with reference to Figure 2 , the milling cutter 4 provided in the embodiments of the present application comprises a first milling edge 41 and a second milling edge 42, wherein the first milling edge 41 and the second milling edge 42 are respectively inclined to the axis of the milling cutter 4 and the inclination directions are opposite. The first milling edge 41 and the second milling edge 42 of each milling cutter 4 correspond to the paint of one corner 51 on the side where the milling cutter 4 is located.

[0065] Specifically, as shown in the figure, Figure 2 , the first milling edge 41 and the second milling edge 42 are arranged in the second direction as a whole, wherein the second direction is perpendicular to the first direction and the length direction of the extension of the flat copper wire 5. The first milling edge 41 and the second milling edge 42 are both inclined to make the first milling edge 41 and the second milling edge 42 cut in the direction parallel or similar to the diagonal direction of the cross section of the flat copper wire 5 as a whole. In this way, if the first milling edge 41 and the second milling edge 42 are straight edges as shown in the figure, Figure 2 , the first milling edge 41 and the second milling edge 42 can mill the corner 51 of the flat copper wire 5 to be chamfered, thereby removing the paint at the corner 51.

[0066] The first milling edge 41 and the second milling edge 42 also avoid the side of the flat copper wire 5. Specifically, as shown in the figure, Figure 2 , the first milling edge 41 and the second milling edge 42 are inclined and the inclination directions are opposite, so that a space for avoiding the side of the flat copper wire 5 is formed between the first milling edge 41 and the second milling edge 42, thereby reducing the removal of the side copper body of the flat copper wire 5 by the first milling edge 41 and the second milling edge 42, and improving the copper retention rate of the flat copper wire 5 after paint removal.

[0067] As an optional implementation, the first milling edge 41 and the second milling edge 42 are arranged in a "<" shape, and the angles formed by the first milling edge 41 and the second milling edge 42 of the two milling cutters 4 are opposite to each other. Specifically, the angles formed by the first milling edge 41 and the second milling edge 42 of the two milling cutters 4 are opposite to each other, which can form a "<>" shape, and the area surrounded by the angles formed by the first milling edge 41 and the second milling edge 42 of the two milling cutters 4 is the space for accommodating the flat copper wire 5. The milling cutter 4 arranged in this way has the characteristics of simple structure, easy processing and good structural strength.

[0068] Of course, in the specific implementation of the milling cutter 4, it is not limited to the above-mentioned implementation.

[0069] As an optional implementation, the milling cutter 4 provided by the embodiment of the application comprises a first milling edge 41 and a second milling edge 42. The first milling edge 41 and the second milling edge 42 of each milling cutter 4 correspond to the paint of a fillet edge 51 on the side where the milling cutter 4 is located; and the first milling edge 41 and the second milling edge 42 avoid the side surface of the flat copper wire 5. The first milling edge 41 and the second milling edge 42 both have an arc shape which is shaped according to the fillet edge 51. For details, please refer to Figure 5 , Figure 5 Another milling cutter provided by the embodiment of the application is shown in the figure. By arranging the first milling edge 41 and the second milling edge 42 of the milling cutter 4 to have an arc shape which is shaped according to the fillet edge 51, when the paint at the fillet edge 51 is removed by the first milling edge 41 and the second milling edge 42, an arc-shaped edge can be reserved at the fillet edge 51, thereby reducing the amount of material removed at the fillet edge 51 and improving the copper retention rate of the flat copper wire 5 after the paint is removed.

[0070] In addition to the main movement of rotation, the milling cutter 4 in the embodiment of the application also needs to perform the movements of feeding, retracting and cooperating with the replacement of the milling cutter 4. The related structure for driving the movement of the milling cutter 4 in the embodiment of the application will be specifically introduced below with reference to the drawings.

[0071] Reference is made to Figure 6 , Figure 6 The driving mechanism for the movement of the milling cutter in the embodiment of the application is shown in the figure. As an optional implementation, the paint removal device provided by the application further comprises a lifting device 6. The lifting device 6 is arranged on the machine table 1 and is used to drive the two milling cutters 4 to move up and down along the second direction. Specifically, the lifting device 6 can realize the lifting of the milling cutter 4 by using a linear motor, a ball screw, hydraulic driving or other ways. And for the two milling cutters 4 in the embodiment of the application, the lifting device 6 can be arranged to synchronously lift the two milling cutters 4, or the lifting device 6 can be arranged to individually lift the two milling cutters 4 by a distance.

[0072] For machining, the tool used is usually a consumable part, and the tool needs to be checked regularly, and when the tool is damaged or worn to a certain extent, the tool needs to be replaced. By setting the lifting device 6, the milling cutter 4 can be lifted in the second direction to move away from the table 1 for carrying the flat copper wire 5, thereby providing a larger operating space for checking the wear of the milling cutter 4 and replacing the milling cutter 4, and facilitating the installation, checking and replacement of the milling cutter 4.

[0073] As an optional embodiment, the lifting device 6 includes a first lifting power member 61, a first lifting platform 62, a second lifting power member 63 and a second lifting platform 64; wherein the first lifting power member 61 and the first lifting platform 62 form a lifting assembly, and the second lifting power member 63 and the second lifting platform 64 form a second lifting assembly. The first lifting assembly and the second lifting assembly respectively drive one milling cutter 4 to lift or drop.

[0074] The feeding device 3 includes a first feeding power member 31, a first tool holder 32, a second feeding power member 33 and a second tool holder 34; wherein the first feeding power member 31 and the first tool holder 32 form a first feeding assembly, and the second feeding power member 33 and the second tool holder 34 form a second feeding assembly, and the first feeding assembly and the second feeding assembly also respectively drive one milling cutter 4 to feed or retract.

[0075] Specifically, one milling cutter 4 is rotationally arranged in the first tool holder 32, and the other milling cutter 4 is rotationally arranged in the second tool holder 34. The first tool holder 32 is slidingly arranged in the first lifting platform 62, and the first lifting platform 62 is slidingly arranged in the table 1; the second tool holder 34 is slidingly arranged in the second lifting platform 64, and the second lifting platform 64 is also slidingly arranged in the table 1.

[0076] The first lifting power member 61 is fixed to the table 1 and is used to drive the first lifting platform 62 to slide relative to the table 1 in the second direction, and the first feeding power member 31 is fixed to the first lifting platform 62 and is used to drive the first tool holder 32 to slide in the first direction; the second lifting power member 63 is fixed to the table 1 and is used to drive the second lifting platform 64 to slide relative to the table 1 in the second direction, and the second feeding power member 33 is fixed to the first lifting platform 62 and is used to drive the second tool holder 34 to slide in the first direction.

[0077] With a specific example of the first lifting assembly and the first feeding assembly. The machine table 1 can be provided with a guide rail extending along the second direction, and the first lifting platform 62 is slidingly arranged on the guide rail. The first lifting power member 61 can be a servo motor, and the servo motor is drivingly connected to the first lifting platform 62 through a screw-nut mechanism, so that the servo motor can drive the first lifting platform 62 to lift or descend along the second direction through the screw-nut mechanism. The first lifting platform 62 is provided with a guide rail extending along the first direction, and the first tool holder 32 is slidingly connected to the guide rail extending along the first direction; the first feeding power member 31 is also a servo motor, which is fixed on the first lifting platform 62 and drivingly connected to the first tool holder 32 through a screw-nut mechanism, so that the first feeding power member 31 can drive the first tool holder 32 to slide in the first direction, and in turn drive the milling cutter 4 to make a feeding motion in the first direction. The specific structure of the second lifting assembly and the second feeding assembly can refer to the description of the first lifting assembly and the first feeding assembly, which will not be repeated here.

[0078] By setting the relatively independent lifting device 6 and the feeding device 3 to respectively drive the two milling cutters 4 to be independently lifted and descended and to feed and retreat, the two milling cutters 4 can be independently controlled, so as to improve the machining precision when the milling cutters 4 mill the rounded edges 51.

[0079] As an optional embodiment, with reference to the above description of the first lifting assembly and the first feeding assembly, Figure 6 When the driving device 2 is specifically set, the driving device 2 includes a first driving member 21 and a second driving member 22; the first driving member 21 is fixedly connected to the first tool holder 32, and the second driving member 22 is fixedly connected to the second tool holder 34. The first driving member 21 is used to drive one of the milling cutters 4 to rotate, and the second driving member 22 is used to drive the other milling cutter 4 to rotate.

[0080] As a specific example, taking the first driving member 21 as an example, the first driving member 21 is fixed to the first tool holder 32, and the milling cutter 4 is rotationally connected to the first tool holder 32 through a main shaft, and the first driving member 21 is drivingly connected to the main shaft through a belt, so as to realize that the first driving member 21 can drive the milling cutter 4 to rotate. Of course, in addition to the above-mentioned mode, the first driving member 21 can also drive the milling cutter 4 to rotate through a chain transmission, a gear transmission and the like. The specific embodiments of the second driving member 22 can refer to the description of the first driving member 21, but it should be pointed out that in specific implementation, the specific embodiments of the first driving member 21 and the second driving member 22 can be the same or different.

[0081] By setting the first driving member 21 and the second driving member 22 to respectively drive the two milling cutters 4 to rotate, the transmission path between each driving member and the milling cutter 4 can be simplified, so as to reduce the failure rate of the transmission path and improve the structural stability of the paint removal device.

[0082] As an optional implementation, the first driving member 21 and the second driving member 22 in the embodiment of the application are both electric motors. The electric motors have the characteristics of fast start-stop response, easy control, and low maintenance cost. The rated speed of the electric motor can be greater than or equal to 5,000 revolutions per minute. The high speed of the electric motor can improve the surface finish of the milled plane after milling and improve the surface quality after the paint on the corner edge 51 of the flat copper wire 5 is removed.

[0083] Reference Figure 7 , Figure 7 FIG. 7 is a schematic view of a bearing table in the embodiment of the application. As an optional implementation, the paint removal device provided in the embodiment of the application further includes a bearing table 7 and a sliding driving member (not shown in the figure). The machine table 1 is slidingly arranged on the bearing table 7, and the sliding driving member is used to drive the machine table 1 to slide along the length direction of the flat copper wire 5 relative to the bearing table 7. That is, during the milling process of the milling cutter 4, the machine table 1 can be driven by the sliding driving member to move along the length direction of the flat copper wire 5, thereby driving the milling cutter 4 to move along the length direction of the flat copper wire 5, so that the milling cutter 4 can mill the corner edge 51 of a length along the length direction of the flat copper wire 5.

[0084] Specifically, the sliding driving member can be in various forms such as a screw nut driving mechanism, a linear motor driving mechanism, and an electric push rod driving mechanism. For the paint removal device provided with the bearing table 7 and the sliding driving member, when the feeding mechanism conveys a section of the flat copper wire 5 to a set position, the flat copper wire 5 can be fixed at the set position, and the length of the paint removal section in the length direction of the flat copper wire 5 can be accurately controlled by the sliding driving member. Such an implementation can improve the processing accuracy of the paint removal device.

[0085] Of course, in some other possible implementations, the machine table 1 can be fixed, and the flat copper wire 5 can be driven by the feeding device to slide in the length direction thereof, so as to realize the relative feeding of the milling cutter 4 along the length direction of the flat copper wire 5.

[0086] As an optional implementation, the paint removal device provided in the application further includes a first positioning assembly 8 and a second positioning assembly (not shown in the figure). Along the length direction of the flat copper wire 5, the first positioning assembly 8 and the second positioning assembly are respectively located on both sides of the working positions of the two milling cutters 4 for removing the paint on the corner edge 51 of the flat copper wire 5. The first positioning assembly 8 and the second positioning assembly are respectively fixedly connected with the machine table 1 and are used to clamp and position the flat copper wire 5.

[0087] Specifically, taking the first positioning assembly 8 as an example, the first positioning assembly 8 can include two cylindrical rollers oppositely arranged along the second direction, and both of the two cylindrical rollers are fixed to the machine table 1 through a hinged support; the first positioning assembly 8 further includes an elastic member, which can drive one of the two cylindrical rollers or simultaneously drive the two cylindrical rollers to move close to each other. The two cylindrical rollers are opposite to each other, and the hinged supports of the two cylindrical rollers enclose a space in which the flat copper wire 5 can be clamped. When the flat copper wire 5 is located between the two cylindrical rollers, in the second direction, the two cylindrical rollers clamp the two side surfaces of the flat copper wire 5, and in the first direction, the side walls of the hinged supports also limit the flat copper wire 5, so that the flat copper wire 5 can be stably fixed to the machine table 1. The specific implementation of the second positioning assembly can refer to the description of the first positioning assembly 8 above.

[0088] The first positioning assembly 8 and the second positioning assembly cooperate with each other, which can further improve the position stability of the flat copper wire 5, thereby further improving the processing precision of the paint removal at the rounded edge 51 of the flat copper wire 5.

[0089] Reference is made to Figure 8 and Figure 9 , Figure 8 is a schematic view of a dust collecting device in an embodiment of the present application, Figure 9 is a schematic view of a dust collecting device in an embodiment of the present application. As an optional implementation, the paint removal device provided in the embodiment of the present application further includes a dust collecting device. The dust collecting device includes a dust collecting box 91, a cover plate 92, and a dust collecting air pipe 93. The dust collecting box 91 is fixed to the machine table 1 and can be used to accommodate the two milling cutters 4, and the dust collecting box 91 further has an opening through which the milling cutters 4 can enter and exit.
