The stator tooling includes a positioning base plate 73 and a stator seat 74 arranged on the positioning base plate 73. The effect of replacing multiple stators can be achieved by replacing the stator tooling, which greatly improves the versatility of the device.

[0024] The first conveying mechanism 8 and the second conveying mechanism 9 are arranged above the automatic conveying mechanism 7 through a gantry mechanism 10. The gantry mechanism 10 includes four columns 101 with reinforcing ribs fixedly connected to the first fixed plate 3. Two cross plates 102 are arranged between the four columns 101. The first conveying mechanism 8 and the second conveying mechanism 9 are arranged between the two cross plates 102. The two cross plates 102 are perpendicular to the automatic conveying mechanism 7. A belt line 103 is arranged above the cross plate 102. The belt line 103 is driven by a belt motor to realize the horizontal movement of the first conveying mechanism 8 and the second conveying mechanism 9.

[0025] The first transport mechanism 8 includes a first transport rail 81 and two first transport grippers 82 arranged on the first transport rail 81. The first transport grippers 82 are driven by the first double-axis cylinder 83 to move up and down, and are driven by the first finger cylinder 84 to clamp and open. When the belt line 103 drives the two first transport grippers 82 placed on the first transport rail 81 to the designated transport position, after the first double-axis cylinder 83 moves downward to the position, the first finger cylinder 84 moves to clamp the stator tooling, and after the first double-axis cylinder 83 moves upward to the position, the belt motor drives the belt line 103 to move to the top of the transfer storage mechanism 11, and after the first double-axis cylinder 83 moves downward to the position, the first finger cylinder 84 moves to release and stably place the stator tooling on the transfer storage mechanism 11.

[0026] The second transport mechanism 9 includes a second transport rail 91 and two second transport grippers 92 arranged on the second transport rail 91. The second transport grippers 92 are driven by the second double-axis cylinder 93 to move up and down, and are driven by the second finger cylinder 94 to clamp and open. When the belt line 103 drives the two second transport grippers 92 placed on the second transport rail 91 to the designated transport position, after the second double-axis cylinder 93 moves downward to the position, the second finger cylinder 94 moves to open and tighten the stator, and after the second double-axis cylinder 93 moves upward to the position, the belt motor drives the belt line 103 to move to the top of the winding seat mechanism 12, and after the second double-axis cylinder 93 moves downward to the position, the second finger cylinder 94 moves to close, so that the stator is smoothly placed in the winding seat mechanism 12. On the contrary, if the steps are reversed, the wound stator can be taken out and placed on the transfer storage mechanism 11.

[0027] The transfer storage mechanism 11 includes a movable guide rail module 111 and four storage stations 112 arranged above the movable guide rail module 111. A mobile sensor is also arranged at the front end of the movable guide rail module 111 to sense whether the stator tooling is in place. The module can move the storage station 112 to a designated position to cooperate with loading and unloading. The four storage stations 112 can place the stator tooling thereon, and can respectively store two stator toolings with unwound product materials and two stator toolings with wound product materials.

[0028] The winding seat mechanism 12 includes two winding motors arranged below the first fixed plate 3 and two stator molds 121 arranged above the first fixed plate 3 and connected to the winding motors. The two winding motors drive the two stator molds 121 to rotate respectively. Stator pressure strips 122 are arranged on both sides of the stator mold 121. The stator pressure strips 122 are driven by the three-axis cylinder 123 to realize the opening and closing of the stator mold 121. When the second transport mechanism 9 transports the stator to the top of the winding seat mechanism 12, the three-axis cylinder 123 can control the stator pressure strips 122 to open so that the stator can be placed in the stator mold 121. When the stator pressure strips 122 are closed, the stator can be firmly fixed to prevent shaking during winding. There is a material in place sensor on both sides of the stator mold 121 to prevent the stator from being placed in place and affecting the yield rate.

[0029] The winding mechanism 13 is connected to the Z-axis casting 63, and the Z-axis motor drives the Z-axis lead screw to move up and down. The Z-axis casting 63 is connected to two winding cylinders 131 and two wire wheel groups 132. The winding cylinder 131 is connected to the winding rod 133. The bottom end of the winding rod 133 is provided with a winding nozzle 134 for inserting the copper wire. The winding cylinder 131 drives the wire nozzle to achieve a 90° flip when winding, and cooperates with the rotation of the winding seat mechanism 12 to achieve the effect of changing slots and passing the wire. The two wire wheel groups 132 can effectively prevent the wire from bending.

[0030] The wire clamping and cutting mechanism 14 includes a movable mold assembly 141 arranged on the second fixed plate 4. The movable mold assembly 141 is controlled by two motors to move forward and backward and up and down. Two wire clamping assemblies 142 and two wire cutting assemblies 143 are arranged on the movable mold assembly 141, which are driven by four compact cylinders 145 respectively, so as to realize the needs of clamping the copper wire before winding and cutting the wire after winding.

[0031] The pay-off rack mechanism 15 is a profile bracket formed by connecting an aluminum profile and an angle code, and is fixedly connected to the third fixed plate 5. A tensioner fixing rod 151 is installed on the profile bracket. The tensioner fixing rod 151 fixes the tensioner 152. A guide porcelain eye 153 is installed at the lower end of the tensioner 152. The guide porcelain eye 153 wraps the copper wire and introduces it into the tensioner 152. The tension required for winding is provided by the tensioner 152.

[0032] When starting work, first put the unwound stator on the stator fixture, and then put the stator fixture on the feeding conveyor belt 712 in the automatic transmission mechanism for transportation. After being sensed by the feeding proximity sensor and positioned by the blocking cylinder 715, the first double-axis cylinder 83 of the two first handling clamps 82 on the first handling mechanism 8 moves downward to the position, and the first finger cylinder 84 clamps the stator fixture. After the first double-axis cylinder 83 moves upward to the position, the belt motor drives the belt line 103 to move to the specified position, and the transfer storage mechanism 11 passes through the mold. The group moves to the designated position, the first double-axis cylinder 83 moves downward, the first finger cylinder moves and releases to place the stator tooling steadily on the transfer storage mechanism 11, and when the four storage stations 112 all sense that there is material, the two second transport grippers 92 on the second transport mechanism 9 transport two of the stators to the top of the winding seat mechanism 12, the stator pressure strip 122 of the winding seat mechanism 12 is opened, the second double-axis cylinder 93 of the second transport gripper 92 moves downward, and the second finger cylinder 94 moves and releases to place the stator steadily into the stator mold 121. The entire three-axis mechanism 6 and the pay-off frame mechanism 15 cooperate with the winding mechanism 13 to send the copper wire to the clamping assembly 142 in the clamping and cutting wire mechanism 14 for clamping, and then move it to the top of the stator mold 121. The winding cylinder 131 on the winding mechanism 13 realizes the 90° flip of the wire nozzle and then cooperates with the rotation of the winding seat mechanism 12 to realize the winding and changing the slot. After winding is completed, the copper wire is sent to the wire cutting assembly 143 in the wire clamping and cutting mechanism 14 for cutting. The second conveying mechanism 9 conveys the copper wire to the transfer storage mechanism 11, and then the other two unwound stators are conveyed to the stator mold 121 for winding. At this time, the first conveying mechanism 8 conveys the wound stators to the return conveyor belt 722 in the automatic transmission mechanism.

[0033] Therefore, the present invention adopts the above-mentioned double-station motor stator inner winding machine with automatic loading and unloading. The stator winding process is completed through an automated structure. The machine replaces manual loading and unloading to improve 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.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
