[0001] The utility model belongs to the technical field of motor stator manufacturing, in particular to an automatic stator winding joint welding device. Background Art

[0002] The hairpin motor is also called the flat wire motor. It has the characteristics of small size, high power and high torque. During the production process of the stator of the hairpin motor, the wire ends of the flat wire group wound on it need to be positioned and tightened, and then the flat wire group needs to be welded using a welding machine.

[0003] At present, in the production process of the stator of the hairpin motor, many manufacturers are still in the state of semi-automatic production with manual clamping, that is, the stator is manually locked on the manual clamp during welding, and then the pressure block is manually adjusted to make the wire ends of the same flat wire group close and positioned, and then welding is performed.

[0004] Regarding the above-mentioned related technologies, the inventor believes that when manually positioning the wire ends of the flat wire group, it is difficult for the stator to ensure that each wire end is moved to the required position, which makes it difficult to ensure the final position of the wire ends of the flat wire group, thereby affecting the quality of the welded products.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0008] Preferably, a shaping assembly is also provided on the processing table, and the shaping assembly includes a group of shaping clamps and a first driving member for controlling the shaping clamps to move closer to or away from each other. The rotating platform can be moved to the position of the shaping assembly. Under the rotation of the rotating platform, the shaping clamps clamp the welded winding joints in turn to achieve the shaping action.

[0009] Preferably, the processing table is also provided with a power-on detection component for detecting whether the stator winding is normally conductive, and the power-on detection component includes a plurality of power-on chucks.

[0034] Example:

The processing table 1 is also provided with a rotating platform 3, and a fixing tool 4 for fixing a stator 5 is installed on the rotating platform 3. When the rotating platform 3 rotates, the fixing tool 4 drives the stator 5 to rotate so that the winding joint 51 is welded by the welding assembly 2 in sequence.

[0036] Among them, participation Figure 2 , Figure 3 The welding assembly 2 uses resistance welding, wherein the welding assembly 2 includes a first fixed frame 21, a welding machine body 22 with two welding heads 221, a welding machine horizontal driving mechanism 23 arranged on the first fixed frame 21 to drive the welding machine body to move horizontally, and a first lifting assembly 24 that drives the welding machine body 22 to move up and down. The processing table 1 is also provided with a smoking mechanism for absorbing smoke generated when the welding machine body 22 welds the winding joint 51. The horizontal driving mechanism can be a conventional linear moving mechanism such as a servo motor and a rodless cylinder. The first lifting assembly 24 can be a cylinder. The smoking mechanism is a conventional smoking mechanism formed by a smoking pipe 9 and a negative pressure suction structure placed around the position where the winding joint 51 is welded. In addition, a connecting plate 26 is fixed to the end of the cylinder piston rod of the first lifting assembly 24, and two first driving cylinders 25 are fixed below the connecting plate 26. The two first driving cylinders 25 respectively control a welding head 221 to achieve the closeness and separation of the two welding heads 221 in the horizontal direction.

[0037] Among them, see Figure 4The processing table 1 is also provided with a shaping component 6, and the shaping component 6 includes a group of shaping clamps 65 and a first driving member 64 for controlling the shaping clamps 65 to move closer to or away from each other. The rotating platform 3 can be moved to the position of the shaping component 6. Under the rotation of the rotating platform 3, the shaping clamps 65 clamp the welded winding joints 51 in turn to achieve the shaping action. The shaping component 6 also includes a second fixed frame 61 and a second lifting component 62. The second lifting component 62 is arranged on the second fixed frame 61 and is used to control the first driving member 64 to perform lifting and lowering movements, wherein the second lifting component 62 can be a cylinder, and a connecting plate 2 is fixed at the end of the cylinder piston rod of the second lifting component 62. The first driving member 64 can be a finger clamp cylinder and is fixed on the connecting plate 2, which respectively controls a shaping clamp 65 to achieve their mutual approach or distance.

[0038] Among them, see Figure 5 The processing table 1 is also provided with a power-on detection component 7 for detecting whether the stator 5 winding is normally conductive. The power-on detection component 7 includes a plurality of power-on chucks. The rotating platform 3 can be moved to the position of the shaping component 6. Each of the power-on chucks can clamp a winding joint 51. The power-on detection component 7 also includes a third fixed frame 71 and a third lifting component 72. The third lifting component 72 is arranged on the third fixed frame 71 and is used to control a plurality of power-on chucks to perform lifting movements at the same time. The third lifting component 72 can be a cylinder. A connecting plate 3 73 is fixed to the end of the piston rod 72, and a plurality of second driving cylinders 74 are fixed on the connecting plate 3 73, and the specific number of the second driving cylinders 74 is configured according to the number of energized chucks required for power-on detection. Each second driving cylinder 74 can be a finger clamp cylinder, and each energized chuck includes two energized clamping blocks 75.

The first driving mechanism 502 can be a conventional linear motion mechanism controlled by a rodless cylinder or a servo motor. An in-position sensor 8 for detecting whether a stator 5 is fixed in a fixed tooling 4 is also arranged on the processing table 1. The fixed tooling 4 includes a placement plate fixed on the rotating platform 3, and a limiting bottom plate 41 for supporting the stator 5 is fixed in the placement plate, wherein at least two positioning blocks 52 are present on the stator 5, and a positioning groove 42 for cooperating with the positioning block 52 is opened on the placement plate. After the positioning block 52 is embedded in the positioning groove 42, the positioning groove 42 limits the movement of the stator 5 in the horizontal direction, and the height of the placement plate is less than the height of the stator 5.

[0040] Working principle and process:

[0041] When using the equipment in the present scheme, the material can be loaded manually or by a robot. The wound stator 5 is placed in the placement tray. During this process, it is necessary to ensure that the positioning block 52 on the stator 5 can be embedded in the positioning groove 42 to realize the positioning of the stator 5. At this time, the in-position sensor 8 will detect whether the stator 5 is placed in the placement tray. The in-position sensor 8 can be an infrared sensor, a photoelectric sensor, etc., and an opening that penetrates the placement tray in the horizontal direction is opened on the placement tray, so that when the placement tray is in the initial position, if the stator 5 is not placed in the placement tray, the in-position sensor 8 can pass through the opening, and after the stator 5 is placed, the in-position sensor 8 cannot pass through the opening to determine whether the stator 5 has been placed in the placement tray; when the in-position sensor 8 has detected the stator 5, the in-position sensor 8 can pass through the opening. The equipment operates normally, the first driving mechanism 502 drives the rotating platform 3 to move along the slide rail 501, and after reaching the position of the welding component 2, the rotating platform 3 rotates according to the set parameters so that the welding component 2 completes the welding of the winding joints 51 in sequence. When the welding is completed, the first driving structure drives the rotating platform 3 to move along the slide rail 501 to the bottom of the shaping component 6, and the rotating platform 3 rotates according to the set parameters so that the shaping component 6 completes the shaping of the winding joints 51 in sequence. Then, after the shaping is completed, the first driving mechanism 502 drives the rotating platform 3 to move along the slide rail 501. After reaching the position of the power-on detection component 7, the rotating platform 3 rotates according to the set parameters so that the power-on detection component 7 completes the power-on detection of the winding joints 51 in sequence. At this point, the equipment completes the entire processing process.
