[0041] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings.

[0043] To facilitate understanding of the laser paint removal device provided in the embodiments of the present application, the application scenarios thereof are first described. The laser paint removal device provided in the embodiments of the present application can be applied to removing the surface paint of a flat copper wire.

[0044] With the development of flat copper wire motor technology, laser paint removal technology is increasingly widely used in the paint removal operation of flat copper wires. Laser paint removal has the advantages of fast paint removal speed, high copper retention rate of flat copper wires after paint removal, and less mechanical damage to flat copper wires.

[0045] For a laser paint removal device, it is usually necessary to arrange several lasers to simultaneously perform paint removal operations on several sides of a flat copper wire. The laser paint removal device in the related art is usually designed and arranged for specific flat copper wire shapes, and has poor adaptability to flat copper wires with different shapes.

[0046] For example, for a laser paint removal device with four lasers, if the arrangement of the lasers is designed based on a square cross-section flat copper wire as a reference in the initial design stage, the four lasers can be arranged uniformly opposite to the four sides of the flat copper wire, so as to ensure that the four lasers evenly share the paint removal area of the surface of the flat copper wire during the paint removal process. However, if the laser paint removal device designed in this way is used to process a flat copper wire with a rectangular cross-section, the paint removal areas corresponding to the four lasers can be different, which can result in a decrease in paint removal efficiency.

[0047] Therefore, the application provides a laser paint removal device, aiming to improve the adaptability of the laser paint removal device to different linear flat copper wires. The laser paint removal device provided by the embodiments of the application will be described below in detail with reference to the drawings.

[0048] Reference is made to Figure 1 and Figure 2 , Figure 1 Figure 1 is a schematic diagram of a laser paint removal device provided by an embodiment of the application, Figure 2 Figure 2 is another schematic diagram of a laser paint removal device provided by an embodiment of the application. The laser paint removal device provided by the embodiments of the application comprises at least two lasers 1, an arc-shaped guide rail 2 and a locking assembly. The laser 1 is used to emit laser beams, and the laser beams emitted by the laser 1 irradiate the surface of the flat copper wire 4, so as to remove the paint on the surface of the flat copper wire 4.

[0049] The arc-shaped guide rail 2 extends along a circumference, each laser 1 is slidingly arranged on a sliding rail, the at least two lasers 1 are distributed at intervals along the arc-shaped guide rail 2, and the emitting end 11 of each laser 1 faces the center of the arc-shaped guide rail 2. The center of the arc-shaped guide rail 2 is provided for the flat copper wire 4 to pass through.

[0050] In some possible embodiments, the laser paint removal device provided by the embodiments of the application can be matched with a feeding device and a clamping device. The feeding device can be used to convey the flat copper wire 4 to pass through the center of the arc-shaped guide rail 2, and the clamping device can be used to guide the conveying of the flat copper wire 4 and clamp and position the flat copper wire 4, so as to facilitate the laser paint removal device to perform the paint removal operation on the flat copper wire 4.

[0051] During the paint removal operation, the emitting end 11 of the laser 1 arranged on the arc-shaped guide rail 2 emits laser beams for the paint removal operation, and the laser beams can remove the paint on the surface of the flat copper wire 4 when irradiating the flat copper wire 4 located at the center of the arc.

[0052] The laser 1 is slidingly arranged on the arc-shaped guide rail 2 and can rotate around the center of the arc-shaped guide rail 2. In this way, the arrangement position of the laser 1 can be adjusted when the laser paint removal device performs the paint removal operation on different linear flat copper wires 4, so that the laser 1 of the laser paint removal device can be kept in an optimal working position when the laser 1 performs the laser paint removal operation on different linear flat copper wires 4.

[0053] In the specific setting position of slidingly arranging the laser 1 on the circular arc guide rail 2, all the lasers 1 can be connected together and then slid as a whole on the circular arc guide rail 2, so that all the lasers 1 can be synchronously linked to rotate; or each laser 1 can be slidably connected with the circular arc guide rail 2, so that the position of each laser 1 can be adjusted individually; or all the lasers 1 can be divided into groups, and then the lasers 1 in each group are connected as a whole and slid on the guide rail as a group, so that part of the lasers 1 in all the lasers 1 can be linked to adjust.

[0054] The locking assembly is used to lock each laser 1 at at least two setting positions on the circular arc guide rail 2. Specifically, the locking assembly can lock a plurality of lasers 1 together on the circular arc guide rail 2, or a plurality of locking assemblies can be provided in one-to-one correspondence with the circular arc guide rail 2, and each locking assembly can be used to lock the corresponding laser 1 at the setting position on the circular arc guide rail 2.

[0055] Here, the setting positions on the circular arc guide rail 2 can be set according to actual production needs. For example, in some possible embodiments, the setting positions can be any positions on the circular arc guide rail 2, so that there can be infinite setting positions on the circular arc guide rail 2. Of course, in other possible embodiments, the setting positions can be two, three, four or more positions that are pre-set according to the common flat copper wire 4 shape.

[0056] In the above technical solution, by slidingly arranging the laser 1 on the circular arc guide rail 2 and locking each laser 1 at at least two setting positions on the circular arc guide rail 2 by the locking assembly, the irradiation angle of the laser 1 to the flat copper wire 4 is adjusted by adjusting the position of the laser 1 on the circular arc guide rail 2, so that the irradiation angle of the laser 1 can be adjusted according to different flat copper wire 4 shapes in the paint removal operation, and the adaptability of the laser paint removal device to different flat copper wire 4 shapes is improved.

[0057] In the specific setting of the laser 1, the number of lasers 1 can be two, three, four, five, six, etc. As an example, the laser paint removal device shown in Figure 1 and Figure 2 has four lasers 1. The adjustment process of the laser 1 of the laser paint removal device provided in the embodiments of the present application will be introduced below in combination with some specific examples.

[0058] Reference is made to Figure 3 and Figure 4 , Figure 3 is one of the laser position diagrams in the embodiments of the present application, Figure 4 is the second laser diagram in the embodiments of the present application. As shown in Figure 3The cross-sectional shape of the flat copper wire 4 shown in the figure is a square. In this case, four lasers 1 can be sequentially arranged at positions facing the four sides of the flat copper wire 4. In this way, each laser 1 can remove the same area of ​​surface paint. All lasers 1 can work together and the paint removal rhythm of each laser 1 tends to be consistent.

[0059] For Figure 4 The cross section of the flat copper wire 4 shown in FIG is rectangular. Figure 3 The four lasers 1 shown in the figure are respectively facing one side of the flat copper wire 4. The paint removal areas of the laser 1 corresponding to the side where the long side of the rectangular cross-section is located and the laser 1 corresponding to the side where the short side is located are different. This may cause inconsistent production rhythms for paint removal on each side, affecting the production efficiency of the laser paint removal device.

[0060] Therefore, when the laser paint removal device provided by the embodiment of the present application is used for Figure 4 When the flat copper wire 4 shown in the figure is subjected to paint removal, the four lasers 1 can be used as Figure 4 Arranged as shown, each laser 1 roughly aligns with an edge of the flat copper wire 4. By adjusting the positions of the lasers 1, the four lasers 1 cover the same paint removal area. This adjustment allows the four lasers 1 to maintain a consistent paint removal rhythm, improving the production efficiency of the laser paint removal system. Furthermore, with this setup, the paint removal load of each laser 1 also tends to be consistent, extending the service life of the laser paint removal system and saving equipment maintenance time and costs.

[0061] It is worth noting that if Figure 3 as well as Figure 4 The beam 5 shown in the figure essentially represents the processing area of ​​each laser 1. In actual production, this processing area can be obtained by scanning a laser beam through a galvanometer. Similarly, during the paint stripping process, the galvanometer can also act on the laser to scan along the length of the rectangular copper wire 4, thereby obtaining a paint stripping section along the length of the rectangular copper wire 4.

[0062] For reference Figure 5 , Figure 5 This is a schematic diagram of the cooperation between the guide rail and the fixed plate in the embodiment of the present application.

[0063] As an optional embodiment, the laser paint removal device includes at least two fixed plates 6, and each fixed plate 6 corresponds to a laser 1. Each fixed plate 6 is slidably connected to the circular arc guide rail 2, and the laser 1 is fixedly connected to the corresponding fixed plate 6. The laser 1 can slide relative to the fixed plate 6 in the diameter direction of the circular arc guide rail 2 and can be locked relative to the fixed plate 6.

[0064] likeFigure 5 In one specific example shown, four fixed plates 6 are provided corresponding to the four lasers 1, and each fixed plate 6 is provided with a sliding structure cooperating with the circular arc guide rail 2 on the side facing the guide rail, which can be a sliding block. The side of the fixed plate 6 away from the circular arc guide rail 2 can be used to fix the laser 1, and the side of the fixed plate 6 away from the circular arc guide rail 2 can be provided with a corresponding sliding structure, and the laser 1 is also in sliding connection with the sliding structure, so that the laser 1 can slide along the diameter direction of the circular arc guide rail 2 relative to the fixed plate 6.

[0065] By providing a fixed plate 6 corresponding to each laser 1, and realizing the sliding connection of the laser 1 and the circular arc guide rail 2 through the fixed plate 6, on the one hand, the stability of the sliding connection of the laser 1 and the circular arc guide rail 2 can be improved by using the fixed plate 6; on the other hand, such arrangement can realize the sliding connection of each laser 1 and the circular arc guide rail 2 respectively, that is, the individual adjustment of any laser 1 can be realized, and such arrangement can improve the adjustment flexibility of the position of the laser 1, and even in some possible embodiments, three of the four lasers 1 can be adjusted to work in a suitable position, while the other laser 1 is turned off, so as to realize the completion of the paint removal work by using three lasers 1.

[0066] Meanwhile, by arranging that the laser 1 can slide along the diameter direction of the circular arc guide rail 2 relative to the fixed plate 6, the distance between the emitting end 11 of the laser 1 and the center of the circular arc guide rail 2 can be adjusted. In the laser paint removal work, not all parts of the laser beam are suitable for paint removal work. After the laser beam is emitted from the emitting end 11 of the laser 1, it will be focused at a position away from the emitting end 11, and the energy density of the light beam on both sides of the focusing position in the light path direction is large, which can be used to remove the paint on the surface of the flat copper wire 4. When the flat copper wire 4 changes in shape or the angle of the laser 1 is adjusted, the distance between the surface of the flat copper wire 4 and the emitting end 11 of the laser 1 may change. Therefore, by adjusting the sliding of the laser 1 along the diameter direction of the circular arc guide rail 2, the position of the laser 1 can be adjusted so that the surface of the flat copper wire 4 is kept at a suitable distance from the emitting end 11 of the laser 1, so that the flat copper wire 4 can always be kept within the suitable working section of the laser beam.

[0067] As an optional implementation, the laser paint removal device in the embodiment of the present application further comprises a focusing device. The number of the focusing device is at least two, and the focusing device corresponds to the laser 1 one by one. The focusing device is used to drive the laser 1 to slide along the diameter direction of the circular arc guide rail 2. Specifically, the focusing device can also be fixed on the side of the fixed plate 6 away from the circular arc guide rail 2. In order to realize the driving of the focusing device to slide the laser 1 along the diameter direction of the circular arc guide rail 2, the focusing device needs to be connected with the laser 1. When the focusing device is connected with the laser 1, the focusing device and the laser 1 can be respectively connected with the fixed plate 6, and then the focusing device and the laser 1 are connected to make the focusing device drive the laser 1 to slide. Of course, the focusing device can also be connected to the fixed plate 6, and then the laser 1 is connected to the focusing device. The laser 1 is not directly connected with the fixed plate 6, but is connected to the fixed plate 6 through the focusing device.

[0068] By setting the focusing device, the operator can conveniently adjust the position of the laser 1 in the diameter direction of the circular arc guide rail 2. Of course, in some optional implementations, the position of the laser 1 in the diameter direction of the circular arc guide rail 2 can also be automatically adjusted.

[0069] Reference is made to Figure 1 , Figure 2 and Figure 6 , Figure 6 The focusing device in the embodiment of the present application is shown in the figure.

[0070] As an optional implementation, the focusing device provided by the embodiment of the present application comprises a fixed part 8 and a sliding part (not shown in the figure, which can be referred to the position of the fixed part). The fixed part 8 is fixed on the fixed plate 6, and the sliding part is in sliding connection with the fixed part 8 and can slide along the diameter direction of the circular arc guide rail 2. The sliding part is connected to the laser 1 and can drive the laser 1 to slide along the diameter direction of the circular arc guide rail 2. Specifically, the laser 1 can be directly fixed to the sliding part and can move with the movement of the sliding part. The fixed part 8 can be a part integrally formed with the fixed plate 6, or a separately produced part which is fixedly connected with the fixed plate 6 by welding, clamping, threaded fasteners or the like.

[0071] The fixed part 8 and the sliding part can be respectively provided with corresponding sliding connection structures, for example, a sliding groove can be provided on the sliding part, and a sliding rail is matched on the fixed part 8. The sliding rail and the sliding groove cooperate to realize the sliding connection of the sliding part and the fixed part 8.

[0072] The driving of the sliding member relative to the fixed member 8 can be achieved by corresponding driving devices, such as servo motors, linear motors, etc. to achieve automatic driving, or by worm gears, gear racks, screw nuts, etc. to achieve manual driving. As a specific example, a screw rod can be provided on the sliding member, and a nut is provided on the fixed member 8, and a hand wheel is provided on one end of the screw rod. By rotating the hand wheel, the screw rod can be rotated, thereby driving the nut to slide relative to the screw rod, and in turn driving the sliding member to slide relative to the fixed member 8.

[0073] It should be understood that when the sliding member is specifically provided to be slidingly connected with the fixed member, corresponding locking structures can be provided to enable the laser 1 to be locked relative to the fixed plate. The specific locking can be achieved by the friction of the driving device itself, or a separate locking component such as a locking bolt can be provided.

[0074] By providing the focusing device including the fixed member 8 and the sliding member, the laser 1 can be stably connected with the fixed plate 6 through the focusing device, and the position of the laser 1 in the diameter direction of the circular arc guide rail 2 can be easily adjusted.

[0075] As an optional embodiment, with reference to Figure 1 , Figure 2 and Figure 6 , the laser paint removal device provided by the embodiment of the present application further comprises a bearing table 7, and the circular arc guide rail 2 is fixed to the bearing table 7. When the laser 1 is locked at a set position on the circular arc guide rail 2 by using the locking assembly, the fixed plate 6 can be locked on the bearing table 7 by using the locking assembly when the laser 1 is at the set position.

[0076] In the center of the circular arc guide rail 2, the bearing table 7 has a passage for the flat copper wire 4 to pass through. As an example, as shown in Figure 1 and Figure 2 , the bearing table 7 can have a circular ring shape, and the hollowed-out area of the inner ring portion can serve as the passage for the flat copper wire 4 to pass through.

[0077] Specifically, the fixed plate 6 can be locked on the bearing table 7 in various ways. As an example, the fixed plate 6 can be abutted with the bearing table 7, and a pressing mechanism can be used to press the fixed plate 6 and the bearing table 7 tightly, thereby locking the fixed plate 6 and the bearing table 7 by friction. Of course, some positioning pins can also be provided to pass through the fixed plate 6 and the bearing table 7, thereby achieving the locking of the fixed plate 6 at a set position on the bearing table 7.

[0078] The locking of the laser 1 at the set position is achieved by locking the fixing plate 6 on the bearing table 7 through the locking assembly. The locking stability can be improved by using the large space on the fixing plate 6 and the bearing table 7, so that the position stability of the laser 1 when locked can be improved, thereby improving the processing precision of the laser paint removal.

[0079] As an optional embodiment, the number of the locking assemblies is at least two, and the locking assemblies correspond to the fixing plates 6 one by one. Figure 1 When the number of the laser 1 and the fixing plate 6 is four as shown in the example, the number of the locking assemblies is also four. Each locking assembly is used to lock the corresponding fixing plate 6 on the bearing table 7.

[0080] Each locking assembly includes a positioning pin, a first fastener, and at least two locking blocks 3. The at least two locking blocks 3 are arranged in the circumferential direction of the circular arc guide rail 2 and are fixed on the bearing table 7. The positioning pin is used to positionally connect the fixing plate 6 and the locking block 3, and the first fastener is used to lock the fixing plate 6 and the locking block 3.

[0081] When the locking block 3 is arranged, the position of each locking block 3 corresponds to a set position of the laser 1, that is, when the fixing plate 6 and the locking block 3 are locked, the laser 1 is just at a preset set position. The positions of all locking blocks 3 in the same locking assembly can correspond to all preset set positions of the laser 1 corresponding to the locking assembly.

[0082] When the laser 1 is at the set position, the first fastener and the positioning pin cooperate to lock the fixing plate 6 and the locking block 3. When the position of the laser 1 is to be adjusted, the fixing plate 6 and the locking block 3 can be unlocked, and then the fixing plate 6 is rotated to the position corresponding to another locking block 3 and locked on the other locking block 3, so that the laser 1 can be locked at different set positions.

[0083] Continuing to refer to Figure 6 , the first fastener can be a threaded fastener, the locking block 3 can be provided with a positioning hole and a threaded hole, and the fixing plate 6 can be provided with corresponding positioning holes and through holes. When the laser 1 reaches the set position, the positioning pin can be arranged in the two positioning holes to achieve positioning connection, and the threaded fastener can pass through the through hole and be fastened in the threaded hole, so as to achieve the locking of the fixing plate 6 and the locking block 3.

[0084] As a specific example, each locking assembly in the embodiment of the present application can include four locking blocks 3, which are respectively fixed on the bearing table 7 at positions corresponding to the positions of the laser 1 at 30°, 45°, 60° and 90° of a 1 / 4 circular arc of the circular arc guide rail 2. Of course, in other possible embodiments, the locking blocks 3 can be fixed on the bearing table 7 at other positions, which can be determined according to the actual position requirements of the laser 1.

[0085] By setting the locking assembly to the above structure, a larger locking force can be provided by the locking of the locking blocks 3 and the fixed plate 6, so as to improve the position stability of the laser 1 when it is locked at the set position, thereby improving the processing precision of the laser paint removal.

[0086] Reference Figure 7 , Figure 7 FIG. 1 is a schematic view of a laser paint removal device according to an embodiment of the present application. As an optional embodiment, the laser paint removal device provided by the embodiment of the present application further includes a dust collection device, which includes a dust collection box 91 and a dust collection pipeline 92. The dust collection box 91 is arranged inside the circular arc guide rail 2 and is fixed relative to the circular arc guide rail 2. Specifically, the dust collection box 91 can be fixedly connected with the circular arc guide rail 2, or can be fixedly connected with the bearing table 7 or other components fixed relative to the circular arc guide rail 2.

[0087] The dust collection box 91 has a space for accommodating the flat copper wire 4 and has a through hole for the flat copper wire 4 to pass through. The side wall of the dust collection box 91 facing the laser 1 is provided with a light transmission hole 911. The flat copper wire 4 can pass through the through hole of the dust collection box 91 to enter the inside of the dust collection box 91, and then the emission end 11 of the laser can emit a laser beam, which can pass through the light transmission hole 911 to enter the inside of the dust collection box 91 and irradiate the flat copper wire 4, so that the paint removal operation can be performed on the flat copper wire 4 in the space for accommodating the flat copper wire 4 inside the dust collection box 91.

[0088] The dust collection pipeline 92 is connected to the inside of the dust collection box 91 and is used for sucking the smoke and dust generated in the paint removal process. Specifically, one end of the dust collection pipeline 92 is connected to the inside of the dust collection box 91, and the other end of the dust collection pipeline 92 is connected with a device capable of generating negative pressure, so as to suck the smoke and dust generated in the laser paint removal.

[0089] By setting the dust collection device, the smoke and dust generated in the laser paint removal process can be reduced, which can reduce the influence of the smoke and dust on the laser on the one hand, and can reduce the influence of the smoke and dust on the electrical elements of the laser paint removal device on the other hand.

[0090] As an optional implementation, when the laser paint removal device comprises the bearing table 7, the dust collection box 91 is rotatably connected with the bearing table 7 and can be locked at a set angle, and when the dust collection box 91 is at the set angle, the light hole 911 corresponds to the emitting end 11 of the laser 1. Specifically, the dust collection box 91 can be rotatably connected with the bearing table 7 through a slide rail, an arc-shaped hole or the like, and the axis of rotation of the dust collection box 91 is the axis extending along the length direction of the flat copper wire 4.

[0091] By arranging the rotatable dust collection box 91, when the angle of the laser 1 is rotated, the dust collection box 91 can be rotated so that the light hole 911 can be aligned with the emitting end 11 of the laser 1, which can reduce the opening area of the light hole 911, thereby reducing the smoke and dust escaping during the laser paint removal process.

[0092] As an optional implementation, one end of the dust collection box 91 for connecting with the bearing table 7 is provided with an arc-shaped hole 912.
