[0040] Please see Figures 1 to 3The stator welding apparatus provided in this application embodiment will now be described. The stator welding apparatus includes a support platform 1 and a spot welding assembly 2. The support platform 1 supports the stator body 10, and the spot welding assembly 2 performs welding on the stator body 10. Optionally, the spot welding assembly 2 includes a spot welding bracket 21, two spot welding heads 22, a spot welding transverse movement unit 23, and a spot welding lifting unit 24. The two spot welding heads 22 are respectively mounted on the spot welding bracket 21, with one of the spot welding heads 22 slidably mounted on the spot welding bracket 21 via a guide rail pair. The spot welding transverse movement unit 23 is mounted on the spot welding bracket 21, and its output end is connected to one of the spot welding heads 22. The spot welding transverse movement unit 23 can be a cylinder / electric cylinder transmission mechanism, a lead screw transmission mechanism, a linear motor, etc., and is not limited to any particular type. The spot welding lifting unit 24 is connected to the spot welding bracket 21, that is, the output end of the spot welding lifting unit 24 is connected to the spot welding bracket 21. This structure supports the stator body 10 via the support platform 1. A spot welding head 22 is driven to reciprocate on the spot welding bracket 21 via the spot welding traverse unit 23, thereby adjusting the distance between the two spot welding heads 22. The spot welding lifting unit 24 drives the spot welding bracket 21 closer to the support platform 1, allowing the two spot welding heads 22 to perform spot welding on the stator body 10. Since the distance between the two spot welding heads 22 can be adjusted according to different types of stator bodies 10, this stator welding device is adaptable to various types of stator bodies 10, thus improving its versatility.

[0041] Please see Figure 1 The stator welding device also includes a frame 20, on which the support platform 1 and the spot welding assembly 2 can be respectively mounted. That is, the spot welding bracket 21 of the spot welding assembly 2 can be mounted on the frame 20. With this structure, the support platform 1 and the spot welding assembly 2 can be positioned, installed and supported by the frame 20 respectively.

[0042] In one embodiment, see Figure 3As a specific embodiment of the stator welding device provided in this application, the stator welding device further includes a rotary drive 11 and a support moving unit 12. The support moving unit 12 can be installed on the frame 20, and the output end of the support moving unit 12 is connected to the rotary drive 11, and the output end of the rotary drive 11 is connected to the support platform 1. The support moving unit 12 can be a cylinder / electric cylinder transmission mechanism, a lead screw transmission mechanism, a linear motor, etc.; the rotary drive 11 can be a rotary motor, etc., and no specific limitation is made here. In this structure, the rotary drive 11 can drive the support platform 1 to rotate, thereby driving the stator body 10 to rotate. This allows for the use of two spot welding heads 22 to perform rotary spot welding on the stator body 10, which helps improve spot welding efficiency. The support moving unit 12 can drive the rotary drive 11 and the support platform 1 to reciprocate, thereby moving the stator body 10 from the feeding end to the spot welding position, and cooperating with the spot welding assembly 2 to perform spot welding on the stator body 10, facilitating the movement of the stator body 10.

[0043] Optionally, a sensing plate is installed on the support platform 1, and a sensor is installed on the rotary drive component 11. This structure, through the sensing interaction between the sensing plate and the sensor, enables the monitoring of the rotation angle of the support platform 1, thus allowing for control of the rotation angle of the support platform 1.

[0044] In one embodiment, see Figure 1 In one specific embodiment of the stator welding apparatus provided in this application, detection elements 13 are respectively installed at both ends of the support moving unit 12, and the two detection elements 13 are arranged opposite to each other. The two detection elements 13 can be respectively installed on the frame 20, and both detection elements 13 can be through-beam optical fibers. With this structure, the two detection elements 13 can detect whether the stator body 10 is contained on the support platform 1, facilitating subsequent spot welding operations.

[0045] In one embodiment, see Figure 2 As a specific embodiment of the stator welding device provided in this application, the spot welding assembly 2 further includes a spot welding displacement seat 25 and a displacement detector 26. The spot welding displacement seat 25 is mounted on the spot welding bracket 21, and the displacement detector 26 is mounted on one of the spot welding heads 22, that is, the displacement detector 26 is mounted on a sliding spot welding head 22. The spot welding displacement seat 25 and the displacement detector 26 are spaced apart along the sliding direction of the spot welding head 22. This structure, through the cooperation of the displacement detector 26 and the spot welding displacement seat 25, allows for monitoring of the movement stroke of one of the spot welding heads 22, preventing the distance between the two spot welding heads 22 from being too large or too small, which would affect the spot welding effect on the stator body 10.

[0046] In one embodiment, see Figure 2As a specific embodiment of the stator welding device provided in this application, the spot welding lifting unit 24 includes a first spot welding transverse module 241, a spot welding lifting module 242, and a second spot welding transverse module 243. The second spot welding transverse module 243 is mounted on the frame 20. The output end of the second spot welding transverse module 243 is connected to the spot welding lifting module 242, and the output end of the spot welding lifting module 242 is connected to the first spot welding transverse module 241. The output end of the first spot welding transverse module 241 is connected to the spot welding bracket 21. The first spot welding transverse module 241, the spot welding lifting module 242, and the second spot welding transverse module 243 can all be pneumatic / electric cylinder transmission mechanisms, lead screw transmission mechanisms, linear motors, etc., and are not limited to any single type. This structure allows the spot welding bracket 21 to move laterally in the horizontal direction via the first spot welding transverse module 241, to move vertically via the spot welding lifting module 242, and to move laterally in the horizontal direction via the second spot welding transverse module 243. This multi-directional adjustment of the positions of the two spot welding heads 22 enables multi-directional spot welding operations on the stator body 10. The movement direction of the first spot welding transverse module 241 is the same as that of the second spot welding transverse module 243.

[0047] In one embodiment, see Figure 2 Two limiting guide rods 2411 are installed at intervals on the first spot welding transverse module 241, and a limiting seat 211 is installed on the spot welding bracket 21, which is located between the two limiting guide rods 2411. With this structure, the horizontal displacement of the spot welding bracket 21 can be limited by the abutting cooperation between the limiting seat 211 and the two limiting guide rods 2411.

[0048] In one embodiment, see Figure 2 As a specific embodiment of the stator welding device provided in this application, the spot welding assembly 2 further includes a pressing seat 27 mounted on the spot welding bracket 21. With this structure, when the spot welding lifting module 242 drives the spot welding bracket 21 to descend, the pressing seat 27 can cooperate with the support platform 1 to clamp and fix the stator body 10, preventing the stator body 10 from shifting position during spot welding and helping to improve the welding effect of the stator body 10. The number of pressing seats 27 can be multiple, and each pressing seat 27 can cooperate with the top position of the stator body 10 to abut.

[0049] In one embodiment, see Figure 4As a specific embodiment of the stator welding device provided in this application, the stator welding device further includes a photographing bracket 3 and a camera 4. The photographing bracket 3 can be mounted on the frame 20, and the camera 4 can be mounted on the photographing bracket 3, with the camera 4 located above the support platform 1. In this structure, the stator body 10, supported by the support platform 1, moves to below the camera 4 via the support moving unit 12, allowing for photographic identification of the stator body 10's posture and position, facilitating subsequent spot welding operations.

[0050] In one embodiment, see Figure 1 and Figure 4 As a specific embodiment of the stator welding device provided in this application, the stator welding device further includes a height measuring component 5. The height measuring component 5 includes a height measuring base 51, a height measuring detector 52, and a height measuring lifting unit 53. The height measuring lifting unit 53 can be mounted on the photographing bracket 3, and its output end is connected to the height measuring base 51. In this structure, the height measuring base 51 and the height measuring detector 52 can be driven to descend via the height measuring lifting unit 53. Through the contact and cooperation between the height measuring detector 52 and the stator body 10, the height of the stator body 10 can be detected.

[0051] In one embodiment, see Figure 4 As a specific embodiment of the stator welding device provided in this application, the height measuring and lifting unit 53 includes a height measuring and lifting plate 531, an elastic element 532, and a height measuring and lifting component 533. The height measuring seat 51 is slidably mounted on the height measuring and lifting plate 531 via a guide rail pair. One end of the elastic element 532 abuts against the height measuring and lifting plate 531, and the other end of the elastic element 532 abuts against the height measuring seat 51. The elastic element 532 can be a spring. The height measuring and lifting component 533 can be mounted on the photographing bracket 3, and the output end of the height measuring and lifting component 533 is connected to the height measuring and lifting plate 531. The height measuring and lifting component 533 can be a cylinder / electric cylinder transmission mechanism, a lead screw transmission mechanism, a linear motor, etc., and is not limited to any particular type. In this structure, the height measuring lifting plate 531 and the height measuring seat 51 can be driven to rise and fall by the height measuring lifting component 533. When the height measuring detector 52 comes into contact with the stator body 10, the elastic component 532 can block and buffer the height measuring seat 51, avoiding hard contact between the height measuring detector 52 and the stator body 10, thus playing a buffering and protective role.

[0052] In one embodiment, see Figure 4 As a specific embodiment of the stator welding device provided in this application, the stator welding device also includes a dust suction pipe 6, which is positioned directly opposite the two spot welding heads 22. The dust suction pipe 6 can be mounted on the photographic bracket 3. In this structure, the dust suction pipe 6 can be connected to a vacuum device to achieve negative pressure, thereby absorbing the exhaust gas generated when the spot welding heads 22 perform spot welding operations on the stator body 10, reducing environmental pollution.

[0053] 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.
