[0053] The clamping end of the clamping mechanism 20 of the second conveying manipulator 92 comprises two oppositely arranged clamping arc-shaped plates 22, and the opposite sides of the two clamping arc-shaped plates 22 cooperate with each other to clamp the stator windings 1 arranged in a ring shape in the circumferential direction. The third conveying manipulator 93 and the fourth conveying manipulator 94 are the same as the second conveying manipulator 92 in structure.

[0054] The incoming material conveyor 3 is a conveying belt, which is a prior art and will not be described in detail. The incoming material conveyor 3 is provided with an incoming material tray 301 on the working surface, and the incoming material tray 301 is provided with a plurality of first placement positions 302 arranged in a linear array. The first placement positions 302 are convex structures and are matched with the positioning grooves 101 of the stator windings 1. The first placement positions 302 are used for positioning the stator windings 1, so that the stator windings 1 placed on the incoming material tray 301 are arranged side by side. The stator production device transports a plurality of stator windings 1 from the feeding end of the incoming material conveyor 3 to the feeding path of the rack 2 through the incoming material conveyor 3. The first carrying manipulator 91 moves back and forth along the feeding path between the incoming material conveyor 3 and the circle assembling mechanism 4 to feed the stator windings 1 arranged side by side.

[0055] Reference Figures 6 to 12 The circle assembling mechanism 4 includes a circle assembling frame 41, a forming sleeve 42, a plurality of circle assembling bodies 43, a support plate 44, a circle assembling driving device 45, and a material lifting device 46. The circle assembling bodies 43 are hingedly connected to each other in a chain structure 10 between the forming sleeve 42 and the support plate 44. The inner side wall of the upper end of the circle assembling bodies 43 is provided with a second placement position 404, which is a convex structure and is matched with the positioning grooves 101 of the stator windings 1. The lower end of the circle assembling bodies 43 is provided with a magnetic element 403.

[0056] The driving end of the circle assembling driving device 45 comprises a connecting frame 405 and two swing arms 406. The connecting frame 405 is slidingly arranged on the circle assembling frame 41. The two swing arms 406 are oppositely arranged and pivotally connected to the two side portions of the connecting frame 405. The swing arms 406 are pivotally connected with connecting tables 407.

The sliding body 408 is slidingly arranged in the sliding groove 409. When the swing cylinder 451 drives the crank 452 to swing, the swing movement of the crank 452 is converted into the linear sliding movement of the connecting frame 405 on the circle assembling frame 41 through the sliding cooperation between the sliding body 408 and the sliding groove 409. The circle assembling driving device 45 drives the connecting frame 405 to linearly translate to approach or move away from the forming sleeve 42. The two swing arms 406 driven by the connecting frame 405 link the chain type structure 10 to be flatly arranged on the supporting plate 44 or to be wrapped in the forming sleeve 42.

[0057] The material lifting device 46 is a telescopic cylinder.

[0058] When the chain type structure 10 is flatly arranged on the supporting plate 44, the circle assembling bodies 43 are magnetically adsorbed on the supporting plate 44 by the magnetic elements 403 to maintain the parallel arrangement of the second placing stations 404, so that the first conveying manipulator 91 can feed the parallel arranged stator windings 1 on the feeding conveyor 3 to the flatly arranged chain type structure 10 of the circle assembling mechanism 4.

[0059] After the stator windings 1 are fed to the flatly arranged chain type structure 10, the circle assembling driving device 45 drives the connecting frame 405 to approach the forming sleeve 42 by overcoming the magnetic attraction force between the magnetic elements 403 and the supporting plate 44.

[0060] When the chain type structure 10 is wrapped in the forming sleeve 42, the circle assembling bodies 43 are magnetically adsorbed on the forming sleeve 42 by the magnetic elements 403 to maintain the annular arrangement of the second placing stations 404, so that the circle assembling operation of the stator windings 1 is completed. The concave-convex cooperation between the inner recesses 102 and the outer protrusions 103 on the opposite sides of the adjacent two stator windings 1 makes the annular arrangement of the stator windings 1.

[0061] After the operation of assembling the stator winding 1, the ejecting device 46 drives the ejecting seat 401 to move upward, so that the inner supporting column 402 is inserted into the annular structure formed by the annularly arranged stator winding 1, and the position of the annularly arranged stator winding 1 is guided, and the annularly arranged stator winding 1 is ejected from the second placing station 404.

The welding frame 2 is provided with a welding displacement device 204, which is composed of a vertical telescopic cylinder and a longitudinal telescopic cylinder. The welding head 52 adopts a laser welding mode, which is a prior art and will not be described in detail here. The welding head 52 is arranged on the displacement end of the welding displacement device 204, and the welding displacement device 204 adjusts the position of the welding head 52 in the vertical and longitudinal directions. The first rotating device 53 is arranged on the welding frame 51, and the first pneumatic chuck 54 is arranged on the rotating end of the first rotating device 53. The first rotating device 53 is a rotary driving device, which is a prior art and will not be described in detail here. The clamping end of the first pneumatic chuck 54 includes a plurality of first clamping jaw portions 501 arranged in a ring shape and at intervals. Each first clamping jaw portion 501 folds inward to clamp the annularly arranged stator winding 1 in the circumferential direction. The first pneumatic chuck 54 converts the axial movement into the radial movement of the sliding block through a connecting rod, so as to drive each first clamping jaw portion 501 to realize the radial folding or spreading action. The first pneumatic chuck 54 is a prior art and will not be described in detail here. The second carrying manipulator 92 feeds the annularly arranged stator winding 1 on the assembling mechanism 4 to the first pneumatic chuck 54 of the welding mechanism 5. The first pneumatic chuck 54 is driven to rotate by the first rotating device 53 to adjust the angle of the annularly arranged stator winding 1, so that the gap between the two adjacent first clamping jaw portions 501 is provided for the welding laser of the welding head 52 to pass through, and it is ensured that the welding head 52 can be aligned in turn and complete the welding work of each stator winding 1.

[0064] The stator production device realizes the automatic operation of the stator winding 1 from positioning, assembling, to welding through the incoming conveyor 3, the assembling mechanism 4, and the welding mechanism 5, significantly reduces the time and workload of manual operation, and improves the production efficiency and product quality.

Guide columns 14 are arranged on both sides of the welding frame 51, and the pressing frame 111 is provided with guide sleeves 15 for slidingly arranging the guide columns 14, so as to guide the lifting movement of the pressing device 11. The welding cover 113 is arranged coaxially with the pressing rod 112 with its opening downward, and the bottom of the welding cover 113 is provided with a plurality of welding ports 16 arranged in a ring array.

The detection end of the detection camera 63 corresponds to the second pneumatic chuck 61. The detection camera 63 is a CCD camera and is known in the art and will not be described in detail here. The detection camera 63 is used to collect image information of the outer side wall of each stator winding 1 arranged in a ring on the second pneumatic chuck 61. The second rotating device 62 drives the second pneumatic chuck 61 to rotate to adjust the angular position of each stator winding 1 arranged in a ring, so that the detection camera 63 can more comprehensively detect the appearance of each stator winding 1 arranged in a ring.
