[0054] Example

[0055] like Figure 1-15As shown, this utility model provides an automatic loading and unloading dual-station motor stator internal winding four-unit winding machine, which consists of four dual-station motor stator internal winding machines connected by an automatic conveying mechanism 7. The dual-station motor stator internal winding machine includes a machine housing 1 and an automatic conveying mechanism 7, a transfer and storage mechanism 11, a winding seat mechanism 12, a wire clamping and cutting mechanism 14, and a three-axis mechanism 6 arranged sequentially on the machine housing 1. A wire feeding frame mechanism 15 is also fixedly connected to the side of the machine housing 1 near the three-axis mechanism 6. A first conveying mechanism 8 and a second conveying mechanism are arranged above the automatic conveying mechanism 7. Structure 9, a three-axis mechanism 6 connected to a winding mechanism 13; a first fixed plate 3, a second fixed plate 4, and a third fixed plate 5 are fixedly installed on the top of the chassis 1; an automatic conveying mechanism 7, a transfer and storage mechanism 11, and a winding seat mechanism 12 are all located above the first fixed plate 3; a wire clamping and cutting mechanism 14 is located above the second fixed plate 4; the three-axis mechanism 6 can move in the X, Y, and Z directions and is located above the third fixed plate 5; the winding mechanism 13 is mounted on the Z-axis component; the automatic conveying mechanism 7 is placed at the front end of the machine and consists of two sets of conveying components, one of which carries the unwound wire to the winding seat. The stator fixtures are used for transporting the winding stator. A set of stator fixtures can transport the winding stator. The first conveying mechanism 8 can transport the unwound product material on the automatic conveying mechanism 7 to the transfer storage mechanism 11 and transport the wound product in the transfer storage mechanism 11 to the automatic conveying mechanism 7. The transfer storage mechanism 11 can store the unwound product and the wound product, and wait for the first conveying mechanism 8 and the second conveying mechanism 9 to handle them. The second conveying mechanism 9 can transport the unwound product in the transfer storage mechanism 11 to the winding base mechanism 12. The winding mechanism 12, through a motor rotation and in conjunction with the winding mechanism 13, achieves precise winding on the stator. The winding mechanism 13 feeds the copper wire to the wire clamping and cutting mechanism 14 for clamping, and then feeds the wire back to the winding mechanism 12 for winding. After the stator winding is completed, the wire is fed by the winding mechanism 13 to the wire clamping and cutting mechanism 14 for cutting. The wire feeding mechanism 15 passes the copper wire through the tensioner 152, which applies winding tension to tighten the wire, achieving the required tension for winding and improving the yield rate. The four four-unit winding machines are connected by a conveyor belt in the automatic conveying mechanism 7. The stator fixture carrying the stator enters from the feeding end 16 and is then conveyed to the next four-unit winding machine. Thus, this four-unit machine can wind at eight stations simultaneously, greatly improving work efficiency and saving labor costs, achieving simple, efficient, and stable stator coil winding.

[0056] The chassis 1 is constructed entirely of welded square tubing, followed by a baked enamel finish, resulting in a clean and aesthetically pleasing appearance. Even during high-speed operation, the machine remains stable and does not wobble, demonstrating high stability. An aluminum profile frame 2 is mounted on top of chassis 1, with the aluminum profiles connected by profile locking clips. The entire frame is screwed to chassis 1. Acrylic windows and sheet metal doors are located around the frame, similar to those around chassis 1, allowing for clear visibility of the machine's operation from the outside. Door stops installed on the profiles effectively prevent swaying when the doors and windows are closed, and proximity sensors 716 ensure operator safety during operation.

[0057] The three-axis mechanism 6 includes an X-axis movement unit, a Y-axis movement unit, and a Z-axis movement unit, consisting of three castings (X, Y, and Z), three motors, and three lead screws. The X-axis movement unit includes an X-axis casting 61, an X-axis motor, and an X-axis lead screw. The X-axis casting 61 is mounted on the third fixed plate 5 via the X-axis lead screw and guide rail. The X-axis motor drives the X-axis lead screw, thus driving the horizontal movement of the X-axis. The Y-axis movement unit includes a Y-axis casting 62, a Y-axis motor, and a Y-axis lead screw. The Y-axis casting 62 is mounted on the X-axis casting 61. The Y-axis motor drives the Y-axis lead screw, thus driving the horizontal movement of the Y-axis. The Z-axis movement unit includes a Z-axis casting 63, a Z-axis motor, and a Z-axis lead screw. The Z-axis casting 63 is mounted on the Y-axis casting 62. The Z-axis motor drives the Z-axis lead screw, thus driving the vertical movement of the Z-axis. Therefore, the three-axis mechanism 6 can achieve movement in three directions and, in conjunction with the winding seat mechanism 12 and the winding mechanism 13, achieve precise winding around the stator.

[0058] The automatic conveying mechanism 7 includes a feeding component 71 and a return component 72. The feeding component 71 is fixed on the first fixed plate 3 by a feeding fixing seat 717, and drives the stator fixture with unwound product material to the designated position. It includes a feeding guide rail 711 and a feeding conveyor belt 712 set on the feeding guide rail 711. The feeding conveyor belt 712 is driven by a feeding motor 713, which is fixed on a motor fixing plate. The stator fixture is set on the feeding conveyor belt 712. The feeding guide rail 711 is also equipped with a feeding speed controller 714, a proximity sensor 716, and a blocking cylinder 715. The blocking cylinder 715 is fixedly connected to the feeding guide rail 711 through a cylinder fixing plate. The stator fixture is placed at the feed end 16. When the proximity sensor 716 on the feeding guide rail 711 detects that the stator fixture has reached the designated position, the blocking cylinder 715 rises, blocking the stator fixture with product material at the designated position and waiting for the first conveying mechanism 8 to carry it.

[0059] The return assembly 72 is fixed to the first fixed plate 3 by the return fixing seat 726, and drives the stator fixture with wound product material to the designated position. It includes a return guide rail 721 and a return conveyor belt 722 mounted on the return guide rail 721. The return conveyor belt 722 is driven by a return motor 723 and also has a stator fixture mounted on it. The return guide rail 721 is also equipped with a return speed controller 724, two proximity sensors 716, and two positioning cylinders 725. When the first conveying mechanism 8 moves the stator fixture above the return conveyor belt 722, the positioning cylinders 725 rise, and the first conveying mechanism 8 places the stator fixture onto the positioning plate on the positioning cylinder 725. When the proximity sensor 716 senses the stator fixture, the positioning cylinder 725 descends, allowing the stator fixture to fall smoothly onto the return conveyor belt 722. To the right of the positioning cylinder 725 is a blocking cylinder 715 and a proximity sensor 716. When the first conveying mechanism 8 is placing the stator fixture, if the second four-unit winding machine has a stator fixture being conveyed via the conveyor belt, the blocking cylinder 715 can prevent the first conveying mechanism 8 from colliding with the conveyed stator fixture. The first and second four-unit winding machines are connected to each other via an automatic conveyor mechanism 7, and the stator fixture can be conveyed via the conveyor belt. The stator fixture includes a positioning base plate 73 and a stator seat 74 mounted on the positioning base plate 73. By changing the stator fixture, multiple stators can be replaced, greatly improving the versatility of the device.

[0060] The first transport mechanism 8 and the second transport mechanism 9 are arranged above the automatic conveying mechanism 7 via a gantry mechanism 10. The gantry mechanism 10 includes four columns 101 reinforced with ribs that are fixedly connected to the first fixed plate 3. Two horizontal plates 102 are arranged between the four columns 101. The first transport mechanism 8 and the second transport mechanism 9 are arranged between the two horizontal plates 102, which are perpendicular to the automatic conveying mechanism 7. A belt conveyor 103 is arranged above the horizontal plates 102. The belt conveyor 103 is driven by a belt motor to realize the horizontal movement of the first transport mechanism 8 and the second transport mechanism 9.

[0061] The first handling mechanism 8 includes a first transverse plate 81 and two first dual-axis cylinders 83 mounted on the first transverse plate 81 via a first cylinder fixing plate 85. The first cylinder fixing plate 85 has a fine-adjusting nut on its side for position adjustment. The bottom ends of the two first dual-axis cylinders 83 are fixedly connected to first finger cylinders 84. First grippers 82 are fixed to the first finger cylinders 84. The first grippers 82 are driven up and down by the first dual-axis cylinders 83 and clamped and opened by the first finger cylinders 84. When the belt conveyor 103 moves the two first grippers 82 placed on the first transverse plate 81 to the designated handling position, after the first dual-axis cylinders 83 move downwards to their designated positions, the first finger cylinders 84 clamp the stator fixture. After the first dual-axis cylinders 83 move upwards to their designated positions, the belt motor drives the belt conveyor 103 to move above the transfer and storage mechanism 11. After the first dual-axis cylinders 83 move downwards to their designated positions, the first finger cylinders 84 release the stator fixture, smoothly placing it on the transfer and storage mechanism 11. When there are two stators with wound wires in the intermediate storage mechanism 11, the first handling mechanism 8 returns to the designated position above the intermediate storage mechanism 11. After the first dual-axis cylinder 83 moves downward to the designated position, the first finger cylinder 84 clamps the stator fixture. After the first dual-axis cylinder 83 moves upward to the designated position, the belt motor drives the belt 103 to move. The first gripper 82 moves to the designated position above the return conveyor belt 722. After the first dual-axis cylinder 83 moves downward to the designated position, the first finger cylinder 84 drives the first gripper 82 to release, and the stator fixture is placed smoothly on the return conveyor belt 722.

[0062] The second transport mechanism 9 includes a second transverse plate 91 and two second dual-axis cylinders 93 mounted on the second transverse plate 91 via a second cylinder fixing plate 95. The second cylinder fixing plate 95 has a fine-adjusting nut on its side for position adjustment. The bottom ends of the two second dual-axis cylinders 93 are fixedly connected to second finger cylinders 94. Second grippers 92 are fixed to the second finger cylinders 94. The second grippers 92 are driven up and down by the second dual-axis cylinders 93 and clamped and opened by the second finger cylinders 94. When the belt conveyor 103 drives the two second grippers 92 placed on the second transverse plate 91 to the designated transport position, after the second dual-axis cylinder 93 moves downward to its designated position, the second finger cylinders 94 open and tighten the stator. After the second dual-axis cylinder 93 moves upward to its designated position, the belt motor drives the belt conveyor 103 to move above the winding seat mechanism 12. After the second dual-axis cylinder 93 moves downward to its designated position, the second finger cylinders 94 close, allowing the stator to be smoothly placed into the winding seat mechanism 12. After the winding is completed, the second transport mechanism 9 returns to the top of the winding seat mechanism 12. After the second dual-axis cylinder 93 moves downward to its position, the second finger cylinder 94 opens and tightens the stator. After the second dual-axis cylinder 93 moves upward to its position, the belt motor drives the belt cable 103 to move. The second gripper 92 moves to the designated position above the transfer and storage mechanism 11. After the second dual-axis cylinder 93 moves downward to its position, the second finger cylinder 94 closes, and the stator is smoothly placed into the stator fixture of the transfer and storage mechanism 11.

[0063] The transfer and storage mechanism 11 includes a movable guide rail module 111 and four storage stations 112 disposed above the movable guide rail module 111. The front end of the movable guide rail module 111 is also provided with a motion sensor 113, which can sense whether the stator fixture is in place. The motion sensor 113 is fixed on the fixed sheet metal. A fine-tuning screw fixing block 114 is provided on one side of the storage station 112 for fine-tuning the position. The module can move the storage station 112 to the designated position to cooperate with loading and unloading. The four storage stations 112 can hold the stator fixtures, and can respectively store two stator fixtures with unwound product materials and two stator fixtures with wound product materials.

[0064] The winding base mechanism 12 includes two winding motors located below the first fixed plate 3 and two stator molds 121 located above the first fixed plate 3 and connected to the winding motors. The two winding motors drive the two stator molds 121 to rotate. Stator pressure bars 122 are provided on both sides of each stator mold 121. The stator pressure bars 122 are driven by a release cylinder 123 to open and close the stator molds 121. When the second conveying mechanism 9 transports the stator to the top of the winding base mechanism 12, the release cylinder 123 controls the stator pressure bars 122 to open, allowing the stator to be placed into the stator molds 121. When the stator pressure bars 122 are closed, they firmly fix the stator, preventing it from shaking during winding. Each side of the stator mold 121 has a material position sensor to prevent improper stator placement, which could affect the yield rate.

[0065] The winding mechanism 13 is connected to the Z-axis casting 63 and is driven by the Z-axis motor to move up and down. The Z-axis casting 63 is connected to two winding cylinders 131 and two guide wheel sets 132 through a fixed plate. The winding cylinders 131 are fixed on the cylinder flipping seat 143 and are connected to the winding rod 133. The bottom end of the winding rod 133 is provided with a winding nozzle 134 for threading copper wire. The winding cylinders 131 drive the nozzle to rotate 90° during winding. This, combined with the rotation of the winding seat mechanism 12, achieves the effect of changing the slot and passing the wire. The two guide wheel sets 132 can effectively prevent the wire from bending.

[0066] The wire clamping and cutting mechanism 14 includes a three-axis assembly fixedly connected to the second fixed plate 4 via a linear bearing 141. The three-axis assembly includes a moving mold assembly 142, which is controlled to move forward and backward and up and down by two motor-driven lead screws. A tilting seat 143 is mounted on the moving mold assembly 142, and a spring is installed inside the tilting seat 143. Two wire clamping assemblies 144 and two wire cutting assemblies 145 are mounted above the tilting seat 143, each driven by four compact cylinders 146. This mechanism fulfills the requirement of clamping the copper wire before winding and cutting the wire after winding.

[0067] The wire feeding frame mechanism 15 is a profile support made of aluminum profile and corner bracket, which is fixedly connected to the third fixing plate 5. A tensioner fixing rod 151 is installed on the profile support, and the tensioner 152 is fixed by the tensioner fixing rod 151. A guide ceramic eye 153 is installed at the lower end of the tensioner 152. The guide ceramic eye 153 wraps around the copper wire and leads it into the tensioner 152, which provides the tension required for winding.

[0068] At the start of operation, the unwound stator is first placed on the stator fixture, which is then placed on the feeding conveyor belt 712 of the automatic transfer mechanism for transport. After being detected by the feeding proximity sensor 716 and positioned by the blocking cylinder 715, the first dual-axis cylinder 83 of the two first grippers 82 on the first handling mechanism 8 moves downward to its designated position. Then, the first finger cylinder 84 clamps the stator fixture. After the first dual-axis cylinder 83 moves upward to its designated position, the belt motor drives the belt conveyor 103 to move to the designated position, where it is transferred to the intermediate storage mechanism 11. After the module moves to the designated position, the first dual-axis cylinder 83 moves downward, and the first finger cylinder 84 releases, smoothly placing the stator fixture onto the transfer and storage mechanism 11. When all four storage stations 112 sense material, the two second grippers 92 on the second transport mechanism 9 transport two of the stators to above the winding seat mechanism 12. The stator pressure bar 122 of the winding seat mechanism 12 opens, the second dual-axis cylinder 93 of the second gripper 92 moves downward, and the second finger cylinder 94 releases, smoothly placing the stator into the stator mold 121. The entire three-axis mechanism 6, together with the wire feeding frame mechanism 15 and the winding mechanism 13, delivers the copper wire to the wire clamping assembly 144 in the wire clamping and cutting mechanism 14 for clamping, and then moves it above the stator mold 121. The winding cylinder 131 on the winding mechanism 13 rotates the wire nozzle 90° and then rotates with the winding seat mechanism 12 to achieve wire winding, wire passing, and slot changing. After winding is completed, the copper wire is sent to the wire cutting component 145 in the wire clamping and cutting mechanism 14 for cutting. It is then transported by the second transport mechanism 9 to the transfer and storage mechanism 11. The other two unwound stators are then transported to the stator mold 121 for winding. At this time, the first transport mechanism 8 transports the wound stators to the return conveyor belt 722 in the automatic transmission mechanism. The positioning cylinder 725 rises, and the first transport mechanism 8 places the stator fixture on the positioning plate on the positioning cylinder 725. When the proximity sensor 716 senses the stator fixture, the positioning cylinder 725 descends, allowing the stator fixture to fall smoothly onto the return conveyor belt 722. The first transport mechanism 8 then transports the two stator fixtures on the feeding conveyor belt 712 to the transfer and storage mechanism 11, so that there are always two stators to be wound in the transfer and storage mechanism 11 after the winding begins.

[0069] Therefore, this utility model adopts the above-mentioned automatic loading and unloading dual-station motor stator internal winding four-unit winding machine. Through the above mechanisms, the automatic winding and automatic loading and unloading of the four-unit machine are realized. The entire process of stator winding is completed by the automated structure. The machine replaces manual loading and unloading, thereby improving efficiency to meet social needs. At the same time, it reduces labor consumption, improves the stability and efficiency of stator winding, and realizes simple, efficient and stable winding of stator coils.
