Description

Technical Field

[0001] This application belongs to the technical field of stator wire harness welding mechanism, and more specifically, relates to a stator wire harness welding mechanism. Background Technology

[0002] In traditional motor stator manufacturing processes, the welding of stator wire harnesses has long relied primarily on manual operation. Due to the complex structure and dense weld points of the stator wire harness, operators need to maintain a high level of concentration for extended periods, resulting in high labor intensity and a high risk of fatigue leading to fluctuations in weld quality. In actual production, the speed of manual welding is difficult to exceed physiological limits, with the welding of a single stator typically taking tens of minutes, becoming a bottleneck restricting overall production efficiency. The quality stability of manual welding is also difficult to guarantee. Differences in the skill levels of different operators and fluctuations in the condition of the same operator at different times can lead to inconsistent weld quality. This instability can range from affecting the consistency of motor performance parameters to potentially causing fatal defects such as incomplete or missing welds.

[0003] As motor products develop towards higher precision and higher performance, the market demands increasingly higher quality and efficiency in stator welding. Traditional manual welding methods can no longer meet the needs of modern intelligent manufacturing. Utility Model Content

The lifting drive component is used to drive the stator fixture to move closer to or away from the welding equipment. The dust collection assembly is located above the stator fixture, and the dust collection port of the dust collection assembly can move closer to or away from the stator fixture.

[0008] As a further improvement to the above technical solution:

The fixed end of the cover drive is connected to the vacuuming bracket. The vacuuming cover is connected to the movable end of the cover drive. The dust removal port of the vacuuming cover is located at the bottom of the vacuuming cover. The cover drive is used to drive the vacuuming cover to cover the stator fixture, or to drive the vacuuming cover to move away from the stator fixture.

[0010] Optionally, the dust collection cover is provided with a notch corresponding to the welding equipment, so that the welding equipment can pass through the dust collection cover and extend into the stator to be welded on the stator tooling.

[0011] Optionally, the projection of the stator fixture along the axial direction is entirely within the projection of the dust collection cover along the axial direction.

[0012] Optionally, the dust collection assembly further includes a dust collection inner cover and an inner cover drive component. The fixed end of the inner cover drive component is connected to the dust collection bracket, and the dust collection inner cover is connected to the movable end of the inner cover drive component.

[0013] Optionally, the outer dust collection cover is provided with a through hole corresponding to the inner dust collection cover, so that the inner dust collection cover can pass through the outer dust collection cover and cover the stator to be welded on the stator tooling.

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] 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 number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] To address the technical problems of low welding efficiency and poor quality consistency in traditional manual welding of stator wire harnesses, such as... Figure 1 As shown, this application provides a stator wire harness welding mechanism, including a stator fixture 1, a lifting drive component 2, a rotating component 3, a welding device 4, and a dust extraction component 5, which achieves efficient and automated welding of the stator wire harness through the coordinated cooperation of each component.

[0033] Specifically, the stator 6 to be welded is positioned and fixed by the stator fixture 1, which is mounted on the rotating assembly 3. The rotating assembly 3 drives the stator fixture 1 and the stator 6 to rotate, ensuring that the welding equipment 4 can cover all the wire harness positions to be welded. The rotating assembly 3 is further mounted on the movable end of the lifting drive component 2, while the fixed end of the lifting drive component 2 is fixed to the external foundation. Driven by the lifting drive component 2, the stator fixture 1 can move vertically, thereby adjusting the relative distance between the stator 6 to be welded and the welding equipment 4, and adjusting the welding position. The lifting drive component 2 can be a hydraulic / pneumatic cylinder, an electric push rod, etc. The welding equipment 4 is used to perform automated welding operations, and its welding parameters can be precisely controlled according to process requirements to ensure consistent welding quality. In addition, the dust extraction assembly 5 is set above the stator fixture 1, and its dust extraction port can be flexibly adjusted to extract smoke and welding spatter during the welding process, effectively improving the working environment and reducing pollution.

[0034] This welding mechanism achieves fully automated welding of stator wire harnesses through the coordinated action of lifting drive component 2, rotating component 3 and welding equipment 4, significantly improving welding efficiency and quality stability.

[0035] like Figure 4 and Figure 5 As shown in a specific embodiment of this application, the dust collection assembly 5 includes a dust collection bracket 51, a dust collection cover 52, and a cover drive 53. The dust collection bracket 51 is fixedly installed on the external base structure, providing a stable support reference for the entire dust collection assembly 5. The fixed end of the cover drive 53 is rigidly connected to the dust collection bracket 51 to ensure the stability of the driving process, while its movable end is connected to the dust collection cover 52. The linear movement of the cover drive 53 drives the dust collection cover 52 to achieve lifting and lowering. The dust collection port of the dust collection cover 52 is located at its bottom edge, covering the outline of the stator fixture 1 to ensure effective collection of welding fumes. The cover drive 53 controls the movement trajectory of the dust collection cover 52. During welding operations, it drives the dust collection cover 52 to descend and completely cover the stator fixture 1; after welding is completed, it drives the dust collection cover 52 to rise and return to its original position, maintaining a safe distance from the stator fixture 1 for easy workpiece loading and unloading.

[0036] like Figure 3As shown, in one specific embodiment of this application, a notch 521 corresponding to the welding equipment 4 is opened on the side wall of the dust collection hood 52. The size and position of this notch 521 must ensure that the welding torch or laser head of the welding equipment 4 can pass through the dust collection hood 52 without obstruction and directly act on the stator 6 to be welded on the stator fixture 1. This enables the welding operation and dust removal function to be carried out simultaneously. The welding equipment 4 can complete the welding operation within the local space formed by the dust collection hood 52, while the dust collection component 5 can promptly extract the fumes and spatter generated during the welding process, effectively solving the technical problem of conflict between dust removal and welding space in traditional welding processes.

[0037] like Figure 4 and Figure 5 As shown in a specific embodiment of this application, the projection range of the dust extraction cover 52 must ensure that its axial projection completely covers the axial projection of the stator fixture 1, so that when the dust extraction cover 52 is lowered to the working position, it can completely cover the stator fixture 1, completely enveloping the stator fixture 1 and the stator 6 to be welded on it. The fumes and spatter generated during the welding process can be effectively controlled within the space formed by the dust extraction cover 52, preventing pollutants from leaking out.

[0038] like Figure 4 and Figure 5 As shown, in a specific embodiment of this application, the dust collection assembly 5 is further configured as a double-layer cover structure, with an additional inner dust collection cover 54 and an inner cover drive component 55 to improve the dust removal effect. The inner dust collection cover 54 is independently controlled by the inner cover drive component 55, wherein the fixed end of the inner cover drive component 55 is rigidly connected to the dust collection bracket 51, and the movable end is connected to the inner dust collection cover 54. The dust collection port of the inner dust collection cover 54 is also located at its bottom edge, making the dust collection port of the inner dust collection cover 54 more concentrated and closer to the stator 6 to be welded on the stator fixture 1. The inner cover drive component 55 can adjust the lifting stroke of the inner dust collection cover 54, allowing it to flexibly adjust the cover position according to the welding process requirements. When the inner dust collection cover 54 is lowered to the working position, the inner dust collection cover 54 is mainly responsible for the dust collection operation on the welding position of the stator 6 to be welded, further improving the dust removal effect.

[0039] like Figure 3 and Figure 5As shown, in one specific embodiment of this application, the top of the dust collection outer cover 52 is provided with a through hole 522 that matches the dust collection inner cover 54. The inner wall of the through hole 522 maintains an appropriate gap with the outer surface of the dust collection inner cover 54 to ensure the free movement of the dust collection inner cover 54. When the inner cover driving member 55 drives the dust collection inner cover 54 to move downward, the dust collection inner cover 54 extends through the through hole 522 into the interior of the dust collection outer cover 52, and finally covers the stator 6 to be welded on the stator fixture 1. This through-type structural design realizes the coordinated operation of the double-layer dust removal system. The dust collection inner cover 54 can directly act on the welding area, while the dust collection outer cover 52 forms an outer protection. The two work together to improve the dust removal efficiency.

[0040] like Figure 2 and Figure 3 As shown in a specific embodiment of this application, the rotating assembly 3 includes a rotating support 31 and a rotating drive 32. The rotating support 31 serves as the mounting base for the stator fixture 1, and the rotating drive 32 is fixedly mounted on the movable end of the lifting drive 2. The rotating drive 32 employs a servo motor or stepper motor, forming a drive connection with the rotating support 31, and works in conjunction with a reduction mechanism to control the angle of the rotating support 31. The stator fixture 1 can rotate smoothly under the drive of the rotating drive 32, ensuring that the stator 6 to be welded rotates accurately to the welding position.

[0041] like Figure 2 and Figure 3 As shown, in a specific embodiment of this application, the connection structure between the rotary support 31 and the stator fixture 1 adopts an insert-type structure to improve positioning accuracy and clamping efficiency. The rotary support 31 is provided with a mating protrusion 311 that matches the bottom shape of the stator fixture 1. The outline dimensions of the mating protrusion 311 must ensure a tight fit with the mounting holes of the stator fixture 1. The stator fixture 1 is directly inserted into the mating protrusion 311 through the bottom mounting holes, achieving self-centering positioning using gravity. This not only simplifies the installation process of the stator fixture 1 but also ensures connection reliability during rotation.

[0042] like Figure 2 and Figure 3 As shown in a specific embodiment of this application, a positioning guide rod 312 is added to the mating protrusion 311 of the rotating support 31 to improve the installation accuracy of the stator fixture 1. The positioning guide rod 312 is located in the radial direction of the stator fixture 1. When the stator fixture 1 is inserted into the mating protrusion 311, the positioning guide rod 312 cooperates with the pre-set positioning hole at the bottom of the stator fixture 1 to achieve circumferential positioning. This retains the convenience of axial insertion and eliminates circumferential movement during rotation through radial positioning. This structure effectively solves the problem of inaccurate circumferential positioning in a single insertion structure and provides a more stable process reference for the welding process.

[0043] like Figure 1 As shown in a specific embodiment of this application, the welding equipment 4 adopts a multi-station arrangement to improve welding efficiency. Specifically, the number of welding equipment 4 is set to at least two, and these welding equipment 4 are distributed in a circular array along the rotation direction of the rotating assembly 3. The installation position of each welding equipment 4 must ensure that when the rotating assembly 3 drives the stator fixture 1 to rotate to different stations, the corresponding welding equipment 4 can accurately align with the position to be welded. This arrangement enables parallel operation of the welding process. When one welding equipment 4 completes the current welding point operation, the rotating assembly 3 can immediately rotate the stator fixture 1 to the next station, and the other welding equipment 4 can continue the operation, thereby shortening the welding cycle. The angular spacing between each welding equipment 4 is optimized according to the welding point distribution of the stator wire harness to ensure that the welding coverage is complete. This multi-station arrangement effectively solves the problem of low efficiency of single welding equipment operation, and significantly improves production efficiency while ensuring welding quality.

[0044] The above description is merely a preferred 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.
