[0085] Please refer to Figure 1 , Figure 3 and Figure 4In one embodiment of the present invention, the stator 10 winding machine includes a frame 100, an indexing mechanism 200, a winding mechanism 300, and an opening and closing mechanism 400. The indexing mechanism 200 is disposed on the frame 100 and has a buffer position for carrying a workpiece. The indexing mechanism 200 drives the buffer position to rotate. The winding mechanism 300 is disposed on the frame 100 and is used to wind the workpiece carried by the buffer position. The opening and closing mechanism 400 is disposed on the frame 100 and has a first position and a second position. In the first position, the opening and closing mechanism 400 forms a processing position, covering the buffer position, and the workpiece carried by the buffer position is exposed in the processing position. In the second position, the opening and closing mechanism 400 moves away from the buffer position so that the buffer position is exposed. At least one of the indexing mechanism 200, the winding mechanism 300, and the opening and closing mechanism 400 is provided, and they are provided in a one-to-one correspondence.

[0086] In the technical solution of this invention, an indexing mechanism 200, a winding mechanism 300, and an opening and closing mechanism 400 are provided on the frame 100. Each indexing mechanism 200 has a buffer position, on which a stator 10 and other workpieces are placed. The stator 10 is positioned by the indexing mechanism 200 and the workpieces such as the stator 10 are rotated by driving the buffer position. Each indexing mechanism 200 is correspondingly provided with an opening and closing mechanism 400 and a winding mechanism 300. The opening and closing mechanism 400 is located close to the buffer position. Since the stator 10 includes multiple stator 10 slots arranged circumferentially, the winding mechanism 300 needs to wind wire around each stator 10 slot circumferentially. The distance between adjacent stator 10 slots is relatively small. The opening and closing mechanism 400 covers the other stator 10 slots that do not need to be wound, exposing only the stator 10 slots that need to be wound. That is, when the opening and closing mechanism 400 is in the first position, such as Figure 4 As shown, the stator slot 10 requiring winding is exposed at the processing position formed by the opening and closing mechanism 400. The stator 10 is fixed in place by the indexing mechanism 200. The winding mechanism 300 winds the exposed stator slot 10 at the processing position. The opening and closing mechanism 400 blocks other stator slot 10, which can prevent winding onto other stator slot 10 during the winding process, thus avoiding affecting motor performance and wasting copper wire. After the stator slot 10 is wound, the indexing mechanism 200 drives the buffer position to rotate, so that the next stator slot 10 rotates to the processing position. The winding mechanism 300 processes the stator slot 10 until all stator slot 10 are wound. At this time, the opening and closing mechanism 400 rotates to the second position, as shown. Figure 3The stator 10 is taken out and placed into the stator 10 that has not been wound, and the above-mentioned action is repeated. By arranging the plurality of opening and closing mechanisms 400, the indexing mechanism 200 and the winding mechanism 300, winding of a plurality of stators 10 can be simultaneously realized, the efficiency of processing the stator 10 is improved, and in the winding process, manual participation is not required, the degree of mechanization is high, the processing efficiency is high, the processing standard is consistent, and the processing quality is guaranteed.

[0087] Specifically, the workpiece in the embodiment can be a stator 10, but is not limited to the stator 10. The stator 10 is taken as a workpiece for expansion and description. The stator 10 includes a plurality of cores arranged circumferentially. When winding the stator 10, each core needs to be wound separately until all the cores are wound. The rack 100 is the basis for realizing the winding process of the entire winding machine and is provided with an indexing mechanism 200, a winding mechanism 300 and an opening and closing mechanism 400. A machine cover (not shown) is arranged above the rack 100 to cover the structures on the rack 100. The machine cover can protect the structures on the rack 100 and avoid dust accumulation. In an embodiment, a wire barrel 120 is arranged on one side of the rack 100. Copper wire is wound in the wire barrel 120. One end of the copper wire passes out of the wire barrel 120 and reaches the winding mechanism 300 through a tensioner 130. The copper wire is wound on the workpiece carried by the indexing mechanism 200 through the winding mechanism 300. The tensioner 130 is arranged to keep the copper wire in a tensioned state to avoid loose accumulation of the copper wire during winding and affect the winding quality. In an embodiment, a gantry is arranged on the top of the rack 100. The indexing mechanism 200 and the opening and closing mechanism 400 are arranged below the gantry. The number of the indexing mechanism 200 and the opening and closing mechanism 400 is not limited. In the embodiment, two indexing mechanisms 200 and two opening and closing mechanisms 400 are arranged. Each opening and closing mechanism 400 is arranged close to one indexing mechanism 200. Each indexing mechanism 200 is further provided with one winding mechanism 300. Each buffering mechanism can buffer the workpiece such as the stator 10. The corresponding opening and closing mechanism 400 is covered, and the stator 10 is wound by the corresponding winding mechanism 300, so that a plurality of stators 10 can be processed at the same time, and the winding efficiency of the stator 10 is improved.

[0088] In an embodiment, a sensor is arranged at the bottom of the gantry corresponding to the position of each indexing mechanism 200, and a scanning mechanism 110 is further arranged at one side of the indexing mechanism 200. The sensor can adopt an optical sensor, which is used to detect whether a workpiece is placed on the buffer position, i.e., whether the workpiece is placed in place. When a stator 10 without winding is placed on the buffer position, the scanning mechanism 110 scans the code of the stator 10, reads and writes the data of the stator 10, so that the MES traces and stores the key winding parameters and the change parameters of each batch.

[0089] In an embodiment, the indexing mechanism 200 can adopt a rotary motor or a rotary cylinder, which is drivingly connected to the buffer position at the output end. The buffer position is driven by the indexing mechanism 200, so that the buffer position can be fixed during winding, thereby ensuring the winding accuracy of the stator 10. When the winding mechanism 300 completes the winding of the slot of one stator 10, the next stator 10 slot needs to be wound. The buffer position is driven to rotate by the indexing mechanism 200, so that the next stator 10 slot is rotated to the processing position to be exposed to the processing position, which facilitates the continuous winding of the winding mechanism 300.

[0090] In the embodiment of the present application, the opening and closing mechanism 400 comprises a mounting seat 4100, a holding assembly 4200, a driving module 4300 and a transmission assembly 4400. The mounting seat 4100 is arranged on the rack 100. The holding assembly 4200 is provided with two holding assemblies 4200, which are rotatably arranged on the mounting seat 4100. The holding assembly 4200 has a positioning part. The driving module 4300 is movably arranged on the mounting seat 4100. Each driving module 4300 is arranged corresponding to each holding assembly 4200. The transmission assembly 4400 is movably arranged on the mounting seat 4100. The driving module 4300 is drivingly connected to the corresponding holding assembly 4200 through the transmission assembly 4400 to drive the holding assembly 4200 to rotate. The holding assembly 4200 has a first position and a second position. In the first position, the two holding assemblies 4200 are close to each other to enclose the outer periphery of the buffer position, and the positioning parts of the two holding assemblies 4200 have a certain interval to form a processing position. In the second position, the two holding assemblies 4200 are far away from each other to expose the buffer position.

[0091] Specifically, please refer to Figure 2 A first seat body 140 is arranged on the rack 100. The mounting seat 4100 is arranged on the first seat body 140, as shown in Figure 3 The mounting seat 4100 is provided with a buffer position for carrying the stator 10 and other workpieces. The driving module 4300 is also arranged on the mounting seat 4100. The driving module 4300 is connected to the holding assembly 4200 through the transmission assembly 4400, so that the holding assembly 4200 can rotate on the mounting seat 4100. When the two holding assemblies 4200 rotate to the first position, as shown in Figure 4As shown, the holding assembly 4200 is located at the front side of the buffer position and close to the setting, the interval between the positioning parts of the two holding assemblies 4200 is the processing position, so that one of the cores of the stator 10 is exposed at the processing position, the exposed part of the stator 10 is waiting for winding processing, and the other part of the stator 10 is shielded by the holding assembly 4200, which can avoid winding to other areas, affect the performance of the motor and cause the waste of enameled wire, when the two holding assemblies 4200 rotate to the second position, the two holding assemblies 4200 rotate in the direction away from each other, the distance between the positioning parts of the two holding assemblies 4200 becomes larger, at this time the whole buffer position is exposed, as shown in Figure 3 As shown, enough space is provided for the taking and placing of the stator 10, so as to take away the stator 10 and the like workpieces after processing, and place the stator 10 and the like workpieces which have not been wound, through the cooperation of the driving module 4300, the transmission assembly 4400 and the holding assembly 4200, the holding assembly 4200 can be quickly opened and closed to provide a surrounding space for the stator 10 carried on the buffer position, so as to avoid the miswinding of copper wire.

[0092] In an embodiment, the driving module 4300 can adopt a linear driving element such as a pneumatic cylinder, a hydraulic cylinder or an electric telescopic rod, which is not limited herein, and the driving module 4300 in the embodiment adopts a pneumatic cylinder, the rotation opening and closing of the holding assembly 4200 is realized by the extension and retraction of the piston rod of the pneumatic cylinder, and the realization mode is simple.

When the output end of the first driving assembly 610 rises, the downward pressure on the driving shaft is released, the elastic structure 631 rebounds, driving the limiting cylinder 620 to rise. At this time, the limiting hole 621 diameter contacted by the driving part 632 of the shearing arm 630 in the limiting hole 621 gradually increases.

Correspondingly, the shearing parts 633 of the two shearing arms 630 also separate, which can be used to clamp the copper wire. Repeating the above operation, the clamping and shearing of the copper wire are completed.
