[0039] Reference Figure 3 、 Figure 4 、 Figure 5 For reference

[0040] The clamping end of the clamping mechanism 20 of the second handling robot 92 includes two clamping straight plates 22 which are oppositely arranged. On the opposite sides of the two clamping straight plates 22, a plurality of first clamping parts 211 and a plurality of second clamping parts 212 which are arranged side by side are respectively provided. The opposite first clamping parts 211 and second clamping parts 212 cooperate with each other to clamp the corresponding stator winding 1.

[0041] The incoming material conveyor 3 is a conveyor belt, which is a prior art and will not be described in detail here. On the working surface of the incoming material conveyor 3, an incoming material tray 301 is provided. On the incoming material tray 301, a plurality of first placement stations 302 which are arranged in a linear array are provided. The first placement stations 302 are convex structures and are in concave-convex fit with the positioning grooves 101 of the stator windings 1. The first placement stations 302 are for positioning and placing the stator windings 1, so that the stator windings 1 placed on the incoming material tray 301 are arranged side by side. This 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 frame 2 through the incoming material conveyor 3, and the first handling robot 91 reciprocates along the feeding path between the incoming material conveyor 3 and the circle assembling mechanism 4 to load the stator windings 1 arranged side by side.

[0042] Reference Figures 6 to 12, the circle - assembling mechanism 4 includes a circle - assembling frame 41, a forming sleeve 42, a number of circle - assembling bodies 43, a support plate 44, a circle - assembling driving device 45, and a blanking device 46 arranged on the circle - assembling frame 41. Each circle - assembling body 43 is hinged to form a chain - type structure 10. The chain - type structure 10 is located between the forming sleeve 42 and the support plate 44. The inner side wall of the upper end of the circle - assembling body 43 is provided with a second placement station 404. The second placement station 404 is a convex structure and is in concave - convex fit with the positioning groove 101 of the stator winding 1. The second placement station 404 is for the stator winding 1 to be positioned and placed. The lower end of the circle - assembling body 43 is provided with a magnetic element 403. The magnetic force between the support plate 44 and the magnetic element 403 is an attractive force, and the magnetic force between the forming sleeve 42 and the magnetic element 403 is also an attractive force. The circle - assembling body 43 is adsorbed on the support plate 44 or the forming sleeve 42 through the magnetic element 403.

[0043] The driving end of the circle - assembling driving device 45 includes a connecting frame 405 and two swing arms 406. The connecting frame 405 is slidably arranged on the circle - assembling frame 41. The two swing arms 406 are arranged oppositely and pivotally connected to the two side parts of the connecting frame 405. The end of the swing arm 406 is pivotally connected with a connecting platform 407. The two connecting platforms 407 are respectively connected to the circle - assembling bodies 43 on the two side parts of the chain - type structure 10. The circle - assembling driving device 45 includes a swing cylinder 451 and a crank 452. The swing end of the swing cylinder 451 is connected to the crank 452. A chute 409 is opened on the connecting frame 405. The other end of the crank 452 is provided with a sliding body 408. The sliding body 408 is a circular structure and is slidably arranged in the chute 409. When the swing cylinder 451 drives the crank 452 to make a swinging motion, through the sliding fit between the sliding body 408 and the chute 409, the swinging motion of the crank 452 is converted into a linear sliding of the connecting frame 405 on the circle - assembling frame 41. The circle - assembling driving device 45 drives the connecting frame 405 to translate linearly closer to or farther away from the forming sleeve 42. Through the two swing arms 406 driven by the connecting frame 405, the chain - type structure 10 is linked to unfold outward on the support plate 44 or to enclose inward on the forming sleeve 42.

[0044] The blanking device 46 is a telescopic cylinder. The blanking end of the blanking device 46 includes a blanking seat 401 and an inner support column 402 arranged coaxially. The blanking seat 401 is slidably arranged in the forming sleeve 42, and the inner support column 402 is inserted into the annular structure formed by the annularly arranged stator windings 1.

[0045] When the chain - type structure 10 unfolds outward on the support plate 44, each circle - assembling body 43 is magnetically adsorbed on the support plate 44 through the magnetic element 403 to maintain the second placement stations 404 arranged side by side, so that the first handling manipulator 91 can load the stator windings 1 arranged side by side on the incoming - material conveyor 3 onto the unfolded chain - type structure 10 of the circle - assembling mechanism 4.

[0046] After each stator winding 1 is loaded onto the flattened chain - type structure 10, the circular - assembling driving device 45 drives the connecting frame 405 to approach the forming sleeve 42 against the magnetic attraction force between each magnetic element 403 and the support plate 44. The chain - type structure 10 is wrapped inwardly around the forming sleeve 42 through the driving of the swing arm 406 and the connecting frame 405.

[0047] When the chain - type structure 10 is wrapped inwardly around the forming sleeve 42, each circular - assembling body 43 is magnetically adsorbed on the forming sleeve 42 by the magnetic element 403 to maintain the annular arrangement of each second placement station 404, thereby completing the circular - assembling operation of each stator winding 1. The concave portions 102 and the convex portions 103 on the opposite sides of two adjacent stator windings 1 are in concave - convex fit, so that each stator winding 1 is annularly arranged.

[0048] After each stator winding 1 completes the circular - assembling operation, the ejecting device 46 drives the ejecting seat 401 to move upward, so that the inner support column 402 is inserted into the annular structure formed by the annularly arranged stator windings 1. While guiding the positions of the annularly arranged stator windings 1, the annularly arranged stator windings 1 are ejected from each second placement station 404.

[0049] The second handling manipulator 92 reciprocates between the circular - assembling mechanism 4 and the welding mechanism 5 along the loading path to load the annularly arranged stator windings 1. The clamping mechanism 20 of the second handling manipulator 92 drives two clamping arc - shaped plates 22 to approach each other, and the opposite sides of the two clamping arc - shaped plates 22 cooperate with each other to clamp the annularly arranged stator windings 1 circumferentially.

[0050] Reference Figures 13 to 16, the welding mechanism 5 includes a welding frame 51, two oppositely arranged welding heads 52, a first rotating device 53 and a first pneumatic chuck 54. A welding displacement device 204 is provided on the frame 2. The welding displacement device 204 is composed of a vertical telescopic cylinder and a longitudinal telescopic cylinder. The welding head 52 uses laser welding, which is prior art and will not be elaborated here in detail. 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 prior art and will not be elaborated here in detail. The clamping end of the first pneumatic chuck 54 includes a plurality of first jaw parts 501 arranged annularly and at intervals. Each first jaw part 501 closes inward to clamp each stator winding 1 arranged annularly in the circumferential direction. The first pneumatic chuck 54 converts the axial movement into the radial movement of the slider through a connecting rod, thereby driving each first jaw part 501 to perform the radial closing or spreading action. The first pneumatic chuck 54 is prior art and will not be elaborated here in detail. The second handling manipulator 92 feeds the stator windings 1 arranged annularly on the circle-assembling mechanism 4 onto the first pneumatic chuck 54 of the welding mechanism 5. The first pneumatic chuck 54 is driven by the first rotating device 53 to rotate to adjust the angle of each stator winding 1 arranged annularly, so that the gap between two adjacent first jaw parts 501 allows the welding laser of the welding head 52 to pass through, ensuring that the welding head 52 can sequentially align and complete the welding work of each stator winding 1.

[0051] This stator production device realizes the automatic operation of each stator winding 1 from positioning, circle-assembling to welding through the incoming material conveyor 3, the circle-assembling mechanism 4 and the welding mechanism 5, significantly reducing the time and workload of manual operation, thereby improving the production efficiency and product quality.

[0052] As a further implementation of the present invention, the welding mechanism 5 further includes two oppositely arranged slag blowers 55. The slag blowers 55 are staggered from the welding head 52. The slag blowers 55 are jet pipes, which are prior art and will not be elaborated here in detail.

The pressing member 11 includes a pressing frame 111, a pressing rod 112 and a welding cover 113. The upper end of the pressing rod 112 is fixedly connected to the pressing frame 111, and a pressing block 13 is rotatably connected to the lower end of the pressing rod 112. 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 the guide columns 14 to slide through, so as to guide the lifting movement of the pressing member 11. The welding cover 113 has an opening facing downwards and is coaxially arranged with the pressing rod 112. A plurality of welding ports 16 evenly distributed in an annular array are penetrated through the bottom of the welding cover 113.

[0054] When the stator windings 1 arranged in a ring are placed on the first pneumatic chuck 54, the pressing lifting device 12 drives the pressing member 11 to move downwards. The pressing block 13 and the first pneumatic chuck 54 cooperate with each other to clamp the stator windings 1 arranged in a ring. The welding cover 113 covers and is rotatably connected to the first pneumatic chuck 54, so as to prevent the welding cover 113 from rotating when the first rotating device 53 drives the first pneumatic chuck 54 to rotate, ensuring that the welding head 52 corresponds to its corresponding welding port 16. The setting of the welding cover 113 can prevent welding slag from splashing everywhere onto the surrounding equipment and causing damage or pollution to it. Preferably, a smoke purifier 205 is further arranged on the frame 2, and the welding cover 113 is communicated with the smoke purifier 205, so as to discharge the smoke generated during the welding process.

[0055] When the welding of the stator windings 1 arranged in a ring is completed, the pressing lifting device 12 drives the pressing member 11 to move upwards to separate it from the first pneumatic chuck 54, and the first rotating device 53 is used to drive the first pneumatic chuck 54 to rotate to adjust the positions of the stator windings 1 arranged in a ring, so as to facilitate the slag blowing operation of the slag blower 55.

[0056] Reference Figure 17 、 Figure 18 、 Figure 19 As a further implementation of the present invention, the finished product appearance detection mechanism 6 includes a second pneumatic chuck 61, a second rotating device 62, a detection camera 63, and two contact displacement sensors 64 arranged oppositely. The second pneumatic chuck 61 is coupled to the rotating end of the second rotating device 62.

[0057] The third handling manipulator 93 reciprocates between the welding mechanism 5 and the finished product appearance inspection mechanism 6 along the feeding path to feed each stator winding 1 arranged in a ring. The third handling manipulator 93 transfers each stator winding 1 arranged in a ring from the first pneumatic chuck 54 to the second pneumatic chuck 61. The detection end of the detection camera 63 corresponds to the second pneumatic chuck 61. The detection camera 63 is a CCD camera, which is a prior art and will not be elaborated in detail here. The detection camera 63 is used to collect the image information of the outer side walls 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 positions of each stator winding 1 arranged in a ring, so that the detection camera 63 can comprehensively perform appearance inspection on each stator winding 1 arranged in a ring.

[0058] The contact displacement sensor 64 is a prior art and will not be elaborated in detail here. Two contact displacement sensors 64 are arranged relatively with the second pneumatic chuck 61 as the center, and the contact displacement sensor 64 is provided with an induction translation mechanism 24. The induction translation mechanism 24 is a telescopic cylinder. The contact displacement sensor 64 approaches or moves away from each stator winding 1 arranged in a ring on the second pneumatic chuck 61 under the drive of the induction translation mechanism 24 to perform outer diameter detection on the ring-shaped workpiece formed by each stator winding 1 arranged in a ring. Before measuring the outer diameter of the ring-shaped workpiece, the two contact displacement sensors 64 are calibrated by an outer diameter ring gauge 23. When the second pneumatic chuck 61 clamps the ring-shaped workpiece, the two contact displacement sensors 64 approach each other under the drive of their respective telescopic cylinders and the induction ends of both are attached to the circumferential side wall of the ring-shaped workpiece. The second rotating device 62 drives the second pneumatic chuck 61 to rotate, so as to adjust the angular position of the ring-shaped workpiece, so that the two contact displacement sensors 64 can measure the outer diameter of the ring-shaped workpiece at different angular positions multiple times, improving the accuracy of the outer diameter detection structure.
