Description

Technical Field

[0001] The present invention relates to the technical field of motor production, and in particular to a laser paint removal system, method and storage medium for a flat wire motor stator hairpin wire. Background Art

[0002] Flat copper wire is an important component of the new energy Hair-pin hairpin motor. During the manufacturing process of the motor, the flat copper wire needs to be welded to the motor. Before welding, the insulating paint of the flat copper wire at the welding part needs to be removed. The paint cleaning needs to be residue-free and not affect the base material, otherwise it will reduce the subsequent welding quality and cause defects.

[0003] Hairpin wire paint removal is a key process in wire forming. Currently, two common methods are used: mechanical and laser. Mechanical paint removal involves scraping the paint off the outside of the flat copper wire using a tool. However, due to tool wear and minor fluctuations in the mechanical structure, mechanical paint removal can be unstable and can damage the copper substrate.

[0004] Laser paint removal involves firing a pulsed laser at the copper wire surface, using the instantaneous high temperature generated by the laser to ablate the paint from all four sides of the flat copper wire. Currently, existing laser paint removal systems typically utilize multiple laser paint removal devices distributed around the wire. For example, there is an existing technology called a laser cleaning device for flat copper wire of a hairpin motor. The device includes a supporting structure, a flat copper wire fixing module located on the supporting structure, several groups of laser cleaning modules, and a dust collecting module located obliquely above the flat copper wire fixing module and capable of removing smoke and dust generated by laser cleaning of the flat copper wire. Several groups of laser cleaning modules are installed on the supporting structure in a circular shape with the flat copper wire fixed along the flat copper wire fixing module. The laser cleaning module includes a laser QCS output head, a QCS adapter module, a scanning galvanometer and a field mirror located below the scanning galvanometer, which are arranged on a sliding device from left to right, and a wind knife module that isolates the smoke generated by cleaning directly below the field mirror lens. The scanning galvanometer can scan the laser pulse point output by the laser QCS output head into a laser cleaning line, and the field mirror can focus the scanned laser cleaning line to the surface of the flat copper wire to complete cleaning. The sliding device can synchronously drive the laser QCS output head, the QCS adapter module and the scanning galvanometer to adjust the focal position of the output laser cleaning line. Three groups of laser cleaning modules evenly distributed in a circular direction are used to remove the paint from the flat copper wire. The three groups of laser cleaning modules evenly distributed in a circular direction emit lasers to the middle flat copper wire to evenly remove the paint on the outside of the flat copper wire.

[0005] Another example is a device for laser cleaning the insulation of flat copper wires. The device includes a fixed base with a transport port for the flat copper wire to pass through. A connecting frame connected to the fixed base is provided in front of the transport port. The connecting frame is provided with two sheaths arranged in front and behind each other and coaxially arranged with the transport port. The sheaths have an air cavity, multiple air inlets are provided on the outer wall of the sheaths, and multiple exhaust holes connected to the air cavity are provided on the inner wall of the sheaths. The area between the two sheaths is the processing area, which is surrounded by multiple laser scanning heads connected to the fixed base. The laser beam emitted by the laser scanning head performs laser cleaning on the cleaning area of ​​the flat copper wire body in the processing area. The protective gas enters the air cavity of the sheath through the air inlet and is blown from the uncleaned section of the flat copper wire body to the cleaning area through the exhaust holes. The device uses four sets of laser scanning heads for laser cleaning.

[0006] Existing laser paint removal devices are typically centered around the flat copper wire to be processed, with multiple groups of laser paint removal devices evenly distributed around the flat copper wire. For a three-way laser paint removal system, the structural solution of evenly distributing the three laser paint removal systems on the same working plane (generally at 120 degrees) has requirements for the size of the flat copper wire due to the focal depth of the laser paint removal system, making it difficult to accommodate multiple flat copper wire size requirements. For a four-set laser paint removal system, the structural solution of evenly distributing the four laser paint removal systems on the same working plane (generally at 90 degrees) places high demands on the optical path design of the laser paint removal system. An unreasonable optical path design may cause laser cross-reflection and burn out of laser components. Even a reasonable optical path design cannot avoid the problem of laser cross-reflection and burn out of laser components due to improper operation during debugging. Moreover, whether it is a three-set or a four-set laser paint removal system, the amount of paint removed at the same location is large, making it difficult to fully remove dust. The accumulation of a large amount of dust causes the laser beam energy to attenuate, affecting the paint removal quality and the service life of the laser components. Summary of the Invention

[0007] The purpose of this application is to address the deficiencies of the above-mentioned background technology and to provide a system, method and storage medium for laser paint removal of the stator hairpin wire of a flat wire motor.

[0013] According to a flat wire motor stator hairpin wire laser paint removal system provided in the present application, the two first laser paint removal devices of the first group of paint removal modules are located above the horizontal plane where the axis of the flat copper wire is located, and are symmetrically arranged with the vertical normal passing through the axis of the flat copper wire as the center; the two second laser paint removal devices of the second group of paint removal modules are located below the horizontal plane where the axis of the flat copper wire is located, and are symmetrically arranged with the vertical normal passing through the axis of the flat copper wire as the center.

[0014] According to a laser paint removal system for a flat wire motor stator hairpin provided by the present application, the first area, the second area, the third area and the fourth area are arranged in sequence along the circumference of the flat copper wire, and adjacent areas at least partially overlap.

[0020] Setting the paint removal parameters of the first laser paint removal device and the second laser paint removal device;

[0021] When the processing position of the rectangular copper wire to be depainted moves to the first processing plane, the first laser depainting device is started to depaint the first area and the second area of ​​the rectangular copper wire;

[0024] A non-transitory computer-readable storage medium stores a computer program, which, when executed by a processor, implements the steps of the above-mentioned method for laser paint removal of a stator hairpin wire of a flat wire motor.

[0025] The advantages of the present application are: 1. The paint removal system of the present application includes four sets of laser paint removal devices. Compared with the traditional ring-shaped arrangement, the present application divides the four sets of paint removal devices into two groups. The two groups of laser paint removal devices respectively form two processing planes, and the two processing planes are arranged at intervals along the movement direction of the flat copper wire, that is, the four groups of laser paint removal devices are staggered in space, which can avoid the emitted laser beams from affecting each other. The paint on the flat copper wire is removed by irradiating the laser beam twice, which can reduce the paint dust at a single paint removal station by 50%, and double the service life of a single focusing lens protection lens, effectively avoiding the problem of laser damage to laser components due to optical path design or debugging errors, and improving the stability of the paint removal system;

[0026] 2. The first laser paint removal device and the second laser paint removal device of the present application are staggered in the vertical direction and the horizontal direction respectively, which can effectively avoid the problem of laser damage to laser components caused by optical path design or debugging errors. The optical paths between them are completely staggered, and the spatial arrangement is very exquisite;

[0027] 3. The first laser paint removal device and the second laser paint removal device of the present application adopt another layout mode, which can be divided by the plane where the axis is located and the normal plane where the axis is located, ensuring that all laser paint removal devices are completely staggered, with extremely high space utilization, and greatly improved paint removal efficiency and dust removal effects;

[0028] 4. The paint removal areas corresponding to each laser paint removal device of this application are adjacent and overlapping, ensuring that all paint can be completely removed in the end, with excellent removal effect;

[0029] 5. This application sets the angle between the first laser beam and the second laser beam to ensure that all the paint can be completely removed in the end, which is convenient for the early layout operation;

[0030] 6. The laser beam of this application is a common laser beam, which is easy and simple to set up;

[0031] 7. The laser beam of this application is equipped with a dust removal device, which can effectively remove the dust generated during the paint removal process, improving the processing environment;

[0032] 8. The laser paint removal device of the present application can be movable and adjustable, and can be adaptively adjusted according to the structure and requirements to be processed, and can perform paint removal operations on flat copper wires of different specifications;

[0033] 9. This application also relates to a method for removing paint from flat copper wires. The overall operation is simple and the efficiency of removing paint from flat copper wires is extremely high. The problem of laser radiation damaging laser components due to optical path design or debugging errors will not occur.

[0034] 10. The present application also relates to a storage medium that can store the above-mentioned paint removal method as a program, so that subsequent laser paint removal operations on the stator hairpin wires of flat wire motors can be performed automatically and efficiently.

[0035] The laser paint removal system of the present application has a simple structure and is highly efficient in paint removal. It will not cause damage to laser components due to laser cross-reflection caused by optical path design or debugging errors, and has great promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0049] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] The present application relates to a laser paint removal system for the stator hairpin of a flat wire motor. The paint removal system of the present application uses four groups of laser paint removal devices to perform paint removal operations on the stator hairpin of the flat wire motor. Unlike the annular distribution of laser paint removal devices in traditional paint removal systems, the four groups of laser paint removal devices in the paint removal system of the present application are spaced in the direction of movement and in the circumferential direction. The processing position on the flat copper wire undergoes two laser paint removal operations, and the paint removal operations are performed at two different positions respectively. Such a spatial arrangement structure and processing method make the four groups of laser paint removal devices completely staggered, and the laser beams generated by the laser paint removal devices will not irradiate other laser paint removal devices, and there will be no influence or interference between them. It effectively avoids the problem of laser cross-shooting damaging laser components due to optical path design or debugging errors, and improves the stability of the paint removal system.

[0051] Specifically, such as Figures 1 to 7 As shown, a flat wire motor stator hairpin wire laser paint removal system of the present application includes a first group of paint removal modules and a second group of paint removal modules. The first group of paint removal modules includes two first laser paint removal devices (such as Figure 1 、 2 , 4, 6 shown in A and B), two first laser paint removal devices emit a first laser beam to the flat copper wire for removing the first circumferential area of ​​the flat copper wire to be painted (such as Figure 2 、 4 , 6 and 8 shown in a) and the second region (as shown in Figure 2 、 4 , 6 and 8 shown in b) of the paint; the two first laser beams form a first processing plane perpendicular to the direction of movement of the flat copper wire.

[0052] The second group of paint removal modules includes two second laser paint removal devices (such as Figure 1 、 3 , 5, 7 shown in C and D), two second laser paint removal devices emit a second laser beam to the flat copper wire for removing the third circumferential area of ​​the flat copper wire (such as Figure 3 、 5 , c) shown in 7 and 8 and the fourth region (as Figure 3 、 5 , 7 and 8 d) of the paint; two second laser beams form a second processing plane perpendicular to the axis of the flat copper wire.

[0053] The first laser paint removal device and the second laser paint removal device of the present application are laser paint removal devices with the same structure and function, but with different installation positions. Figure 9As shown, each laser paint removal device comprises a laser system sealed chamber 1, a laser system component mounting base 2, a laser isolator output head 3, a beam expander 4, a galvanometer 5, a focusing lens 6, and a dust removal device 7. The laser system sealed chamber 1 is a hollow, sealed cavity structure, and the main components of the laser paint removal device are installed within it. The laser system component mounting base 2 is a mounting and supporting base for the components, facilitating the fixed installation of the laser paint removal device components. The laser isolator output head 3 is used to emit laser light. The beam expander 4, galvanometer 5, and focusing lens 6 are lenses in the laser light path, used to expand, adjust the direction, and focus the laser light. The dust removal device 7 is used to absorb dust generated during the paint removal process. The first and second laser beams in this application can be pulsed fiber lasers or continuous fiber lasers, and can be selected based on actual needs. The beam expander 4 can be added or removed based on actual optical path requirements. The galvanometer 5 in this application can be air-cooled or water-cooled. The dust removal device 7 uses a bamboo tube or air knife for dust removal.

[0054] The first processing plane and the second processing plane of the present application are spaced apart in the moving direction of the flat copper wire, and the first area, the second area, the third area and the fourth area cover the processing position of the flat copper wire along the circumferential direction, ensuring that all paint films at the processing position of the flat copper wire can be completely removed.

[0055] In actual application, you can follow the steps below:

[0056] Setting the paint removal parameters of the first laser paint removal device and the second laser paint removal device;

[0057] When the processing position of the rectangular copper wire to be depainted moves to the first processing plane, the first laser depainting device is started to depaint the first area and the second area of ​​the rectangular copper wire;

[0058] After the paint is removed from the first and second areas, the position of the rectangular copper wire to be processed is moved to the second processing plane, and the second laser paint removal device is started to remove the paint from the third and fourth areas of the rectangular copper wire;

[0059] Complete the paint removal operation on the flat copper wire.

[0060] That is, the paint removal operation of the flat copper wire of the present application is carried out in two steps. The flat copper wire moves in a set direction, such as Figure 1 As shown, the movement is along the axis of the rectangular copper wire, that is, in the left-right direction. When the processing position of the rectangular copper wire moves to the first processing plane, the first laser paint removal device removes the paint from the first and second areas of the processing position. The rectangular copper wire then moves to the second processing plane, and the second laser paint removal device removes the paint from the third and fourth areas of the processing position.

[0061] By splitting the paint stripping operation into two steps, the optical paths of the four laser stripping units are no longer aligned. This effectively prevents damage to laser components caused by cross-laser beams due to optical path design or commissioning errors, improving the stability of the paint stripping system. The laser stripping units, which might have previously been arranged in a mutually opposite manner, are now staggered in the direction of motion of the flat copper wire, ensuring that their optical paths remain aligned.

[0062] In some embodiments of the present application, the spatial distribution of the above-mentioned laser paint removal device is optimized. Specifically, Figures 1 to 3 As shown, the two first laser paint removal devices of the first group of paint removal modules are respectively placed above and on one side of the flat copper wire, and the two second laser paint removal devices of the second group of paint removal modules are respectively placed below and on the opposite side of the flat copper wire. That is, the first laser paint removal device A and the second laser paint removal device C are respectively placed on the upper and lower sides of the flat copper wire, but the two are spaced apart in the direction of movement of the flat copper wire. The first laser paint removal device B and the second laser paint removal device D are respectively placed on the horizontal sides of the flat copper wire, and the two are spaced apart in the direction of movement of the flat copper wire. Although the laser paint removal devices of the same group (such as A and B, or C and D) are in the same processing plane, the laser beams emitted are crossed but not opposite.

[0063] Another layout mode is Figures 2-4 As shown, the two first laser paint removal devices of the first paint removal module are located above the horizontal plane of the flat copper wire axis and are symmetrically arranged with the vertical normal passing through the flat copper wire axis as the center. The two second laser paint removal devices of the second paint removal module are located below the horizontal plane of the flat copper wire axis and are symmetrically arranged with the vertical normal passing through the flat copper wire axis as the center. That is, the first laser paint removal device A and the first laser paint removal device B are located above the flat copper wire and emit laser beams from top to bottom to process the flat copper wire. The laser beams emitted by the first laser paint removal device A and the first laser paint removal device B, that is, the extensions of the first laser beam, intersect with each other. The second laser paint removal device C and the second laser paint removal device D are located below the flat copper wire and emit laser beams from bottom to top to process the flat copper wire. The laser beams emitted by the second laser paint removal device C and the second laser paint removal device D, that is, the extensions of the second laser beam, intersect with each other. That is, the two first laser beams are used to remove the paint on the side above the processing position of the flat copper wire, and the two second laser beams are used to remove the paint on the side below the processing position of the flat copper wire.

[0064] It can also be Figures 5-6In the illustrated arrangement, the two first laser paint removal devices of the first paint removal module are located on one side of the vertical plane in which the axis of the flat copper wire lies, and are arranged symmetrically with the horizontal plane in which the axis of the flat copper wire lies as the center. The two second laser paint removal devices of the second paint removal module are located on the opposite side of the vertical plane in which the axis of the flat copper wire lies, and are arranged symmetrically with the horizontal plane in which the axis of the flat copper wire lies as the center. That is, the first laser paint removal devices A and B are located on one horizontal side of the flat copper wire, and the second laser paint removal devices C and D are located on the opposite horizontal side of the flat copper wire. The two first laser beams are used to remove the paint on the horizontal side of the flat copper wire processing position, and the two second laser beams are used to remove the paint on the opposite horizontal side of the flat copper wire processing position.

[0065] In this embodiment, the included angle between the two first laser beams in the first processing plane is 80° to 100°, and the included angle between the two second laser beams in the second processing plane is 80° to 100°. Preferably, the included angle between the two first laser beams in the first processing plane is 90°, and the included angle between the two second laser beams in the second processing plane is 90°. As long as the first and second areas processed by the first laser beam and the third and fourth areas processed by the second laser beam completely cover the circumference of the processing position of the flat copper wire, it is ensured that all paint skin at the processing position is completely removed.

[0066] like Figure 8 As shown, this is the distribution of the first area, the second area, the third area and the fourth area. In order to ensure that the first area, the second area, the third area and the fourth area can completely cover the processing position, the first area, the second area, the third area and the fourth area of ​​this embodiment are arranged in sequence along the circumference of the flat copper wire, and there is at least partial overlap between adjacent areas.

[0067] Ideally, the edges of the first, second, third, and fourth areas should fit snugly together, just enough to remove the paint coating at the processing location on the flat copper wire without damaging the internal copper assembly due to overexposure. In practice, to completely remove the paint coating, a margin is typically left, resulting in some overlap between adjacent areas.

[0068] In other embodiments of the present application, this embodiment optimizes the above-mentioned paint removal module. Specifically, the two laser paint removal devices in at least one of the two groups of paint removal modules are movable laser paint removal devices that can be synchronously adjusted along the movement direction of the flat copper wire.

[0069] At least one set of paint removal modules is designed as a movable and adjustable device structure, so as to adapt to hairpin wires of different specifications.

[0070] In actual application, you can follow the steps below:

[0071] Setting the paint removal parameters of the first laser paint removal device and the second laser paint removal device;

[0072] If the hairpin wire to be depainted is a standard length, when the processing position of the flat copper wire to be depainted moves to the first processing plane, the first laser depainting device is started to depaint the first area and the second area of ​​the flat copper wire; after the paint in the first and second areas is removed, the processing position of the flat copper wire moves to the second processing plane, and the second laser depainting device is started to depaint the third and fourth areas of the flat copper wire, thereby completing the depainting operation on the flat copper wire;

[0073] If the hairpin wire to be depainted is of a special length, when the processing position of the flat copper wire to be depainted moves to the first processing plane, the first laser depainting device is started to depaint the first area and the second area of ​​the flat copper wire; after the paint in the first and second areas is removed, the processing position of the flat copper wire moves to the second processing plane, the second laser depainting device is driven by the servo motor to move to a pre-calculated position, and the second laser depainting device is started to depaint the third area and the fourth area of ​​the flat copper wire, thereby completing the depainting operation on the flat copper wire.
