[0002] With the development of industrial technology, motors are being used more and more widely, and people are putting forward higher and higher requirements for automated motor assembly equipment. In the process of motor assembly, the stator is first wound, and after the winding is completed, the enamel stripping mechanism is used to remove the enamel from the stator wire ends.

[0003] Currently, existing paint stripping equipment, including a rotating platform and a paint stripping mechanism, involves placing the stator on the rotating platform and driving the paint stripping mechanism to strip the stator from the platform. However, since the stator is directly placed on the rotating platform, its positional accuracy is difficult to guarantee. The stator is prone to displacement between itself and the rotating platform as it rotates, which can damage the copper wire substrate during the paint stripping process, resulting in scrapped copper wires and a high defect rate.

[0022] As 1 to Figure 7 As shown, the laser paint stripping device 100 provided in this embodiment includes: a substrate 11; a turntable 20 rotatably supported on the substrate 11 with its center as the axis; a tooling bracket 30 for supporting the stator 200 and setting the stator 200 and the turntable 20 coaxially, the tooling bracket 30 being detachably connected to the turntable 20, the tooling bracket 30 including a wire locking portion 30a for fixing the wire end of the copper wire 201 in the winding of the stator 200; and a laser mechanism 40 supported on the substrate 11 and used to strip the paint layer on the surface of the copper wire 201.

[0023] The aforementioned laser paint stripping equipment 100 includes a turntable 20, a tooling bracket 30, and a laser mechanism 40. The tooling bracket 30 is detachably connected to the turntable 20. The stator 200 is supported on the turntable 20 by the tooling bracket 30 and the stator 200 is coaxial with the turntable 20. In this way, by supporting the stator 200 through the tooling bracket 30, the paint stripping accuracy and effect can be improved, and the yield rate can be guaranteed.

[0024] Referring to Figures 1 to 7, the laser paint stripping equipment 100 provided in this embodiment includes a frame 10 and a turntable 20, a tooling bracket 30, and a laser mechanism 40 supported on the frame 10. In this embodiment, the frame 10 includes a base plate 11, which divides the frame 10 into an upper part 12 and a lower part 13. The turntable 20 is rotatably supported on the base plate 11 with its center as an axis and is located in the upper part 12. A rotary drive (not shown) is installed in the lower part 13. The rotary drive is, but is not limited to, a motor. The rotary drive is connected to the turntable 20 and can drive the turntable 20 to rotate. The laser mechanism 40 is disposed through the base plate 11 and partially inserted into the upper part 12. The upper part 12 has a pick-and-place window 121, so that the tooling bracket 30 and the stator 200 can be fed into and removed from the upper part 12 of the frame 10 through the pick-and-place window 121.

[0025] See Figures 1 to 4The laser mechanism 40 provided in this embodiment is supported on the substrate 11 and used to peel off the paint layer on the surface of the copper wire 201. In this embodiment, the laser mechanism 40 includes lasers 41, and the number of lasers 41 is not limited to three. The three lasers 41 are arranged at equal angles around the center line of the turntable 20 on the substrate 11 and located outside the turntable 20. The three lasers 41 are arranged at an included angle of 120°. The lasers generated by the three lasers 41 irradiate the same copper wire 201. In this way, by setting three lasers 41 and arranging them at 120° intervals around the center of the turntable 20, the three lasers 41 can irradiate the paint layer on the surface of the copper wire 201 at the paint stripping position from three directions, thereby peeling off the paint layer of the copper wire 201. After the paint stripping of the copper wire 201 is completed, the turntable 20 rotates, so that the next copper wire 201 is moved into the paint stripping position for the next copper wire 201 to be stripped. In this way, the paint layer on the copper wire 201 can be completely peeled off from the copper wire 201 substrate to ensure the paint stripping effect.

[0026] See Figures 1 to 7 The tooling bracket 30 provided in this embodiment is used to support the stator 200 and make the stator 200 and the turntable 20 coaxially arranged. The tooling bracket 30 is detachably connected to the turntable 20. The tooling bracket 30 includes a wire locking part 30a for fixing the wire end of the copper wire 201 in the winding of the stator 200.

[0027] See Figures 4 to 7 The tooling bracket 30 provided in this embodiment includes an assembly base 31 for mounting the stator 200 and a connecting base 32 arranged alternately with the assembly base 31. The connecting base 32 is provided with a wire locking part 30a. A paint stripping space 30b is constructed between the assembly base 31 and the connecting base 32 for the laser mechanism 40 to generate laser and contact the copper wire 201. In this embodiment, the lengths of the assembly base 31 and the connecting base 32 are basically the same. A fixed shaft 33 is connected between the assembly base 31 and the connecting base 32. The end of the fixed shaft 33 can be connected and fixed to the assembly base 31 and the connecting base 32 by any existing fixed connection method such as threads, welding, or fasteners. It should be noted that after the stator 200 is connected to the assembly base 31, the copper wire 201 is passed through the assembly base 31 and the connecting base 32 in sequence, and the copper wire 201 is straightened and locked and fixed by the wire locking part 30a.

[0028] See Figure 4 and Figure 5 The assembly base 31 provided in this embodiment has an assembly groove 311 for inserting and removing the end of the stator 200. The assembly groove 311 penetrates the top and bottom surfaces of the assembly base 31. In this embodiment, the shape of the assembly groove 311 is not limited to a circle, and the radius of the assembly groove 311 is adapted to the radius of the stator 200. In this way, after the end of the stator 200 is inserted into the assembly groove 311, the movement of the stator 200 on the assembly base 31 can be restricted.

[0029] In other embodiments, the stator 200 can directly abut against the surface of the mounting base 31, and a plurality of limiting structures are provided on the surface of the stator 200 to abut against the sidewall of the stator 200.

[0030] See Figures 5 to 7 In this embodiment, a limiting baffle 34 is provided in the assembly groove 311 to restrict the stator 200 from moving relative to the assembly base 31 along its axial direction. The limiting baffle 34 has a first through groove 341 and a plurality of first wire-clamping slots 342 for fixing copper wires 201. The plurality of first wire-clamping slots 342 are arranged at intervals along the circumference of the limiting baffle 34 and communicate with the first through groove 341. In this embodiment, the shape of the limiting baffle 34 matches the shape of the assembly groove 311. The shape of the limiting baffle 34 is not limited to circular. The limiting baffle 34 is installed at one end of the assembly base 31 near the connecting seat 32. The limiting baffle 34 can be fixed to the assembly base 31 by any existing fixing connection method such as threads, welding, or fasteners. The limiting baffle 34 is used to abut against the end of the stator 200 to restrict the stator 200 from moving relative to the assembly base 31 along its axial direction. The first through groove 341 penetrates the top and bottom surfaces of the limiting baffle 34, and the groove wall of the first through groove 341 faces outward. The recess forms the first wire-locking slot 342. The number of the first wire-locking slots 342 is not limited to six. The six first wire-locking slots 342 are arranged at equal intervals along the circumference of the limiting baffle 34. In this way, the limiting baffle 34 can limit the movement of the stator 200 in the axial direction and position the stator 200 in the axial direction. After the stator 200 is installed into the mounting slot 311 of the mounting base 31, the copper wire 201 passes through the first through slot 341 of the limiting baffle 34 and is locked into the corresponding first wire-locking slot 342, thereby fixing the copper wire 201 to the limiting baffle 34.

[0031] See Figures 5 to 7The connector 32 provided in this embodiment has a second through groove 321 corresponding to the first through groove 341 and a plurality of second wire-locking slots 322 for fixing copper wires 201. The plurality of second wire-locking slots 322 are arranged at intervals along the circumference of the connector 32 and communicate with the second through groove 321. The plurality of second wire-locking slots 322 are respectively aligned with the plurality of first wire-locking slots 342. In this embodiment, the second through groove 321 penetrates the top and bottom surfaces of the connector 32. The shape and size of the second through groove 321 are adapted to the first through groove 341. The groove wall of the second through groove 321 is recessed outward to form the second wire-locking slots 322. The number of second wire-locking slots 322 is not limited to six. The six second wire-locking slots 322 are arranged at equal intervals along the circumference of the connector 32 and are respectively aligned with the six first wire-locking slots 342. In this way, the second wire-locking slots provided in the second through groove 321 322, the copper wire 201 can be fixed to the connecting seat 32. It should be noted that when installing the stator 200 to be stripped and the tooling bracket 30, after the copper wire 201 passes through the first through groove 341 and the second through groove 321 in sequence, the copper wire 201 is straightened along the axial direction of the stator 200 and inserted into the corresponding first wire clamping groove 342 and second wire clamping groove 322. The copper wire 201 is fixed by the first wire clamping groove 342 and the second wire clamping groove 322 to ensure the straightness of the copper wire 201, thereby ensuring the stripping accuracy and stripping effect.

[0032] In other embodiments, wire holes for the copper wire 201 to pass through can also be provided on the mounting base 31 and the connecting base 32.

[0033] See Figure 5 In this embodiment, a circumferential limiting structure 35 is provided between the stator 200 and the mounting base 31 to limit the relative rotation of the stator 200 and the mounting base 31. In this embodiment, the circumferential limiting structure 35 includes a circumferential limiting block 351 disposed on the mounting base 31. The number of circumferential limiting blocks 351 is not limited to two. The surface of the circumferential limiting block 351 is provided with a limiting protrusion 352 protruding towards the center direction of the mounting groove 311. The surface of the stator 200 begins to have a circumferential limiting groove 202 extending along its axial direction for the limiting protrusion 352 to slide into and out. The circumferential limiting block 351 is detachably connected to the mounting base 31, and the limiting protrusion 352 is located in the mounting groove 311. In this way, when the stator 200 is installed, the stator 200 can be positioned in the circumferential direction by the circumferential limiting block 351, and after the circumferential limiting block 351 slides into the circumferential limiting groove 202 of the stator 200, the stator 200 is fixed in the circumferential direction to restrict the rotation of the stator 200 relative to the mounting base 31.

[0034] See Figure 6 and Figure 7The locking part 30a provided in this embodiment includes wire clamps 36 disposed on the side of the connecting seat 32 away from the mounting seat 31. The wire clamps 36 are arranged at intervals along the circumference of the connecting seat 32, and each wire clamp 36 has a winding groove 361 for winding the copper wire 201. In this embodiment, the number of wire clamps 36 is not limited to six. The six wire clamps 36 can be fixed to the connecting seat 32 by any existing fixing connection method such as threads, welding, fasteners, etc. The six wire clamps 36 are respectively aligned with the six second wire clamping slots 322. The winding groove 361 on each wire clamp 36 extends along the circumference of the wire clamp 36. In this way, the wire end of the copper wire 201 can be fixed by winding the wire end into the winding groove 361 of the wire clamp 36.

[0035] See Figure 4 and Figure 5 In this embodiment, the connecting seat 32 has a first positioning hole 323, and the turntable 20 has a second positioning hole 21 that cooperates with the first positioning hole 323 for positioning. In this embodiment, the first positioning hole 323 is a through hole, and the second positioning hole 21 is a threaded hole. After the connecting seat 32 is placed on the turntable 20, a positioning pin (not shown) passes through the first positioning hole 323 and connects with the second positioning hole 21, thereby fixing the tooling bracket 30 on the turntable 20.

In this embodiment, the temporary storage seat 141 has a cross-section that is not limited to a circle, and it has a temporary storage groove for the stator 200 to be placed in. The radius of the temporary storage groove matches the radius of the stator 200. It should be noted that when the laser mechanism 40 strips paint from the stator 200 in the upper part 12 of the frame 10, the stator 200 located in the temporary storage seat 141 can be assembled with the tooling bracket 30 on the transfer operating table 14, thereby improving work efficiency and saving work costs.
