Description

Technical Field

[0001] This application belongs to the field of motor manufacturing, and more specifically, relates to a stator laser welding machine. Background Technology

[0002] Enamelled wire is a type of metal conductor coated with insulating varnish, and it is a key raw material for motors. Currently, laser welding is mostly used for welding enamelled wire and solder pads. The entire welding process requires multiple steps, including welding and wire trimming, to achieve the welding of the enamelled wire and solder pads. These multiple steps involve multiple pieces of equipment, which process the workpieces sequentially to obtain the welded finished product. Although automated assembly line welding of enamelled wire and solder pads can be achieved, the sequential processing of multiple pieces of workpieces requires a large production space to accommodate these devices. Each piece of equipment has its own dimensions and working area, and space must also be left between the devices for workpiece transfer and buffering, resulting in a large space occupation.

[0030] In the description of this application, it should be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Therefore, the phrase "in one embodiment" or "in some embodiments" appears in various places throughout the specification, and not all references are to the same embodiment. Furthermore, in one or more embodiments, particular features, structures, or characteristics may be combined in any suitable manner.

[0033] The stator assembly includes stator windings and enameled wire. The enameled wire is soldered to the stator windings via pads, and the leads of the enameled wire protruding from the pads need to be trimmed.

[0034] Please see Figure 1 The stator laser welding machine provided in this application embodiment will now be described. The stator laser welding machine includes a support plate 110, a support frame 120, a wire cutting mechanism 500, and a welding mechanism 200, a flipping mechanism 300, and a clamping mechanism 400 that are slidably mounted on the support frame 120 along a first direction X. The support plate 110 is provided with a first station 111 and a second station 112 for placing the stator assembly 10 along the first direction X. The welding mechanism 200 is used to weld the stator assembly 10 located at the first station 111. The flipping mechanism 300 is used to flip the stator assembly 10 at the first station 111 around the second direction Y. The wire cutting mechanism 500 is mounted on the support plate 110 and is used to cut the wire of the stator assembly 10 located at the second station 112. The first direction X, the second direction Y, and the vertical direction Z are perpendicular to each other.

[0035] The stator assembly 10 is fed to the first station 111, where the welding mechanism 200 welds the stator assembly 10. The flipping mechanism 300 flips the welded stator assembly 10, and the clamping mechanism 400 transports the stator assembly 10 from the first station 111 to the second station 112. The wire cutting mechanism 500 cuts off the excess enameled wire of the stator assembly 10 located at the second station 112. The welding mechanism 200, flipping mechanism 300, and clamping mechanism 400 are slidably mounted on the support frame 120 along the first direction X, avoiding the spatial dispersion problem caused by the independent setting of each mechanism in traditional equipment. The stator laser welding machine integrates the welding and wire cutting processes, effectively reducing the size of the stator laser welding machine.

[0036] In this application, when the stator assembly 10 is at the first station 111, the enameled wire is at the top, which facilitates the welding mechanism 200 to weld the enameled wire from top to bottom. After welding is completed, the flipping mechanism 300 flips the stator assembly 10 so that the enameled wire faces downward. The clamping mechanism 400 transports the stator assembly 10 to the second station 112, and the wire cutting mechanism 500 cuts off the downward-facing wire ends of the enameled wire. The wire ends can fall off under gravity and separate from the stator assembly 10.

[0037] Specifically, the first station 111 is provided with a base for placing the stator assembly 10.

[0038] Specifically, the support frame 120 is provided with a slide rail and a first sliding drive member 121. The welding mechanism 200, the flipping mechanism 300, and the clamping mechanism 400 are slidably mounted on the slide rail. The length direction of the slide rail is consistent with the first direction X. The first sliding drive member 121 drives the welding mechanism 200, the flipping mechanism 300, and the clamping mechanism 400 to slide along the slide rail. For example, the first sliding drive member 121 drives the welding mechanism 200 to slide to the first station 111 to perform welding operations; then, the first sliding drive member 121 drives the flipping mechanism 300 to slide to the first station 111 to flip the stator assembly 10; then, the first sliding drive member 121 drives the clamping mechanism 400 to slide to the first station 111 to clamp the stator assembly 10, and then drives the clamping mechanism 400 to slide to the second station 112 to place the stator assembly 10 in the second station 112; finally, the wire cutting mechanism 500 cuts off the enameled wire leads of the stator assembly 10 at the second station 112.

[0039] It is understood that in other embodiments, the welding mechanism 200, the flipping mechanism 300 and the clamping mechanism 400 are slidably mounted on the support frame 120, and the welding mechanism 200, the flipping mechanism 300 and the clamping mechanism 400 are each configured with independent sliding drive components to achieve independent sliding on the support frame 120 along the first direction X.

[0040] In one embodiment, see Figure 1 and Figure 2 As a specific embodiment of the stator laser welding machine provided in this application, the welding mechanism 200 includes a first lifting drive 210, a first rotating drive 220 and a laser welding assembly 230. The first lifting drive 210 is slidably mounted on the support frame 120. The first lifting drive 210 drives the first rotating drive 220 to move up and down in the vertical direction Z. The first rotating drive 220 drives the laser welding assembly 230 to rotate around the vertical direction Z.

[0041] The first lifting drive component 210 drives the laser welding assembly 230 to move vertically Z-axis, adjusting the distance between the laser focus and the welding pad surface to ensure stable welding energy density. The first rotation drive component 220 adjusts the welding angle, improving the versatility of the laser welding assembly 230.

[0042] In this embodiment, the laser welding assembly 230 is a commonly used component in the welding field, which is usually composed of a laser generator and an optical focusing system. It is a mature existing technology and will not be described in detail here.

[0043] In one embodiment, see Figure 1 and Figure 2 As a specific embodiment of the stator laser welding machine provided in this application, the support plate 110 and the support frame 120 are distributed at intervals along the second direction Y. The first lifting drive member 210 is installed on the side of the support frame 120 near the support plate 110. The welding mechanism 200 also includes a first mounting frame 240, which is connected to the output end of the first lifting drive member 210. The first mounting frame 240 is located on the side of the first lifting drive member 210 near the support plate 110.

[0044] Both the first lifting drive component 210 and the first mounting bracket 240 are located on the side of the support frame 120 near the support plate 110, closer to the first station 111 on the support plate 110, thus avoiding an increase in the overall lateral dimension of the laser welding assembly 230 due to its distance from the first station 111.

[0045] In one embodiment, see Figure 1 and Figure 3 As a specific embodiment of the stator laser welding machine provided in this application, the flipping mechanism 300 includes a second rotary drive 310 and a first clamp 320. The second rotary drive 310 is slidably mounted on the support frame 120 along the first direction X. The second rotary drive 310 drives the first clamp 320 to rotate around the second direction Y. The first clamp 320 is used to clamp and release the stator assembly 10. The second rotary drive 310 drives the first clamp 320 to rotate around the second direction Y, thereby flipping the stator assembly 10.

[0046] In one embodiment, see Figure 1 and Figure 3 As a specific embodiment of the stator laser welding machine provided in this application, the first clamp 320 includes a pneumatic drive 321 and two grippers 322. The pneumatic drive 321 is mounted on the output end of the second rotary drive 310. One end of each gripper 322 is spaced apart from the output end of the pneumatic drive 321. The pneumatic drive 321 drives the ends of the two grippers 322 to rotate, so that the other ends of the two grippers 322 move closer to or further away from each other. The two grippers 322 open and close synchronously through the rotation of their ends, thereby clamping and releasing the stator assembly 10.

[0047] In one embodiment, see Figure 1 and Figure 3 As a specific embodiment of the stator laser welding machine provided in this application, the gripper 322 is equipped with a clamping block 323. The clamping block 323 is located on the side of the gripper 322 near the other gripper 322, and the side of the clamping block 323 near the other gripper 322 has a conforming arc surface 324. The conforming arc surface 324 is adapted to the side profile of the stator assembly 10, with a larger contact area, which can evenly distribute the clamping force and prevent the stator assembly 10 from slipping due to uneven force during the flipping process.

[0048] In one embodiment, see Figure 1 and Figure 4 As a specific embodiment of the stator laser welding machine provided in this application, the clamping mechanism 400 includes a second lifting drive 410, a tensioning drive 420, and a plurality of tensioning claws 430 distributed at Z intervals around the vertical direction. The second lifting drive 410 is mounted on the support frame 120. The second lifting drive 410 drives the tensioning drive 420 to perform lifting and lowering movements, and the tensioning drive 420 drives the plurality of tensioning claws 430 to close or separate from each other.

[0049] The tension-closing drive 420 drives multiple tension-closing claws 430 to close together. The second lifting drive 410 drives the tension-closing drive 420 to descend, thereby inserting the closed multiple tension-closing claws 430 into the stator assembly 10. The tension-closing drive 420 drives the multiple tension-closing claws 430 to separate from each other, and the multiple tension-closing claws 430 abut against the inner ring of the stator assembly 10, thereby clamping the stator assembly 10. The second lifting drive 410 drives the tension-closing drive 420 to move upward. Then, the clamping mechanism 400 slides on the support frame 120 and moves from the first station 111 to the second station 112, realizing the transfer of the stator assembly 10 to the second station 112.

[0050] In one embodiment, see Figure 1 , Figure 5 and Figure 6As a specific embodiment of the stator laser welding machine provided in this application, the second station 112 is a mounting through hole. The wire cutting mechanism 500 includes a rotating component 510 and a wire cutting component 520. The rotating component 510 includes a rotating disk 511 and a third rotating drive component 512. The rotating disk 511 is rotatably mounted on the second station 112. The rotating disk 511 has a wire cutting hole 513 for fixing the stator assembly 10. The third rotating drive component 512 is mounted on the support plate 110 and drives the rotating disk 511 to rotate around the vertical direction Z. The wire cutting component 520 is mounted below the support plate 110 and is located next to the wire cutting hole 513 to cut the wires of the stator assembly 10.

[0051] The second station 112 is designed with a through hole, allowing the stator assembly 10 to be placed in the wire-cutting hole 513 of the rotary disk 511, so that the wires to be cut can extend downwards to below the support plate 110. The wire-cutting assembly 520 is installed below the support plate 110, avoiding the obstruction of the wire-cutting action by the support plate 110, and can extend to the wires below the support plate 110 for cutting. After each wire is cut, the third rotary drive 512 drives the rotary disk 511 to rotate around the vertical direction Z by a preset angle, that is, the stator assembly 10 fixed to the rotary disk 511 rotates accordingly, so that the wires at different angles are aligned with the wire-cutting assembly 520 in sequence. The wire-cutting assembly 520 can be moved to cover all wire positions.

[0052] In one embodiment, see Figure 5 and Figure 6 As a specific embodiment of the stator laser welding machine provided in this application, the wire cutting assembly 520 includes a third lifting drive 521, a radial telescopic drive 522, a pneumatic gripper 523, and a scissor section 524. The third lifting drive 521 drives the radial telescopic drive 522 to perform lifting movements. The radial telescopic drive 522 drives the pneumatic gripper 523 to approach or move away from the vertical axis of the wire cutting hole 513. The pneumatic gripper 523 drives the scissor section 524 to open and close. The scissor section 524 flexibly moves to a position to grip the wire foot through the third lifting drive 521 and the radial telescopic drive 522, and opens and closes through the pneumatic gripper 523, thereby cutting off the wire foot and completing a cycle of opening, closing, cutting, and reopening to achieve continuous and efficient wire cutting and improve cutting efficiency.

[0053] In one embodiment, see Figure 5 and Figure 6 As a specific embodiment of the stator laser welding machine provided in this application, there are multiple wire cutting components 520, which are circumferentially spaced around the wire cutting hole 513. During the rotation of the stator assembly 10 driven by the rotating disk 511, the multiple wire cutting components 520 simultaneously cut multiple sets of wire leads, improving wire cutting efficiency.

[0054] Specifically, the outer wall of the wire cutting hole 513 is provided with a plurality of partition plates 515, which are arranged parallel to the radial direction of the wire cutting hole 513 and are spaced apart along the circumference of the wire cutting hole 513, thereby dividing the external space of the wire cutting hole 513 into a plurality of regions, and a wire cutting assembly 520 is placed in each region.

[0055] In one embodiment, see Figure 5 and Figure 6 As a specific embodiment of the stator laser welding machine provided in this application, the sidewall of the wire cutting hole 513 has a notch 514, which allows a single scissor section 524 to extend into. When a wire leads rotate to the notch 514, the scissor section 524, driven by the radial telescopic drive member 522, passes through the notch 514 and enters the wire cutting hole 513 to cut the wire leads, then exits the wire cutting hole 513 through the notch 514. Next, the next wire leads rotate to the notch 514, and the scissor section 524 again passes through the notch 514 and enters the wire cutting hole 513 to cut the wire leads, and this cycle repeats.

[0056] In one embodiment, see Figure 1 and Figure 5 As a specific embodiment of the stator laser welding machine provided in this application, the wire cutting mechanism 500 further includes a photoelectric detection component 530. The photoelectric detection component 530 is installed above the support plate 110 and is used to detect whether there is a stator component 10 in the wire cutting hole 513. After the photoelectric detection component 530 confirms that the stator component 10 is correctly positioned through optical signals (such as infrared or laser), the third rotary drive component 512 drives the rotary disk 511 to rotate, and the wire cutting component 520 starts cutting, avoiding process errors caused by the absence of the stator component 10.

[0057] In one embodiment, see Figure 1 and Figure 5 As a specific embodiment of the stator laser welding machine provided in this application, the wire cutting mechanism 500 further includes a waste recycling component 540. The waste recycling component 540 includes a recycling channel 541 and a recycling box 542. One end of the recycling channel 541 is located below the wire cutting component 520, and the other end of the recycling channel 541 extends downward to the recycling box 542. The wire ends cut by the wire cutting component 520 fall into the recycling channel 541 located below the wire cutting component 520 and are guided into the recycling box 542 along the recycling channel 541, which facilitates recycling and improves cleanliness.

[0058] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0059] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
