The upper end of the connecting shaft 54 is provided with a boss 56 along the circumferential direction of the connecting shaft 54, and the output end of the material receiving power mechanism one is connected to the lower surface of the boss 56. The inner circle of the material receiving cylinder 50 is provided with a material receiving abutting wheel two 53 connected to the material receiving abutting wheel one 23. When the material receiving power mechanism two 7 drives the bottom plate 47 to drive the material receiving mold mechanism 6 to move horizontally to the lower side of the winding device, the material receiving power mechanism one drives the connecting shaft 54 to drive the material receiving fixed plate 49 to move upward along the longitudinal direction, so that the material receiving abutting wheel two 53 in the material receiving cylinder 50 is in engagement with the material receiving abutting wheel one 23 at the lower end of the material receiving power shaft 18. Since the upper surface of the boss 56 and the lower surface of the material receiving fixed plate 49 are provided with a bearing three 57, the material receiving fixed plate 49 and the material receiving cylinder 50 can rotate under the driving of the material receiving power shaft 18, and the rotating speed is the same as the winding speed of the stator core punching piece, so that the winding and material receiving are synchronized.

[0050] As shown in Figure 13 to Figure 15To avoid the distance of the falling of the stator core punching sheet being too large, affecting the engagement between the tooth slot of the stator core punching sheet and the slot sign 52, the outer surface of the material collecting cylinder 50 is provided with an annular material collecting follower plate 58, and the material collecting follower plate 58 is provided with a through hole four 59 for the slot sign 52 to pass through along the circumferential direction of the material collecting follower plate 58. The material collecting cylinder 50 is provided with a connecting rib 60 along the radial direction of the material collecting cylinder 50. In the embodiment, the number of the connecting rib 60 is four, which are evenly distributed along the circumferential direction of the material collecting cylinder 50. The side wall of the material collecting cylinder 50 is sequentially provided with a through hole five 61 corresponding to the connecting rib 60 along the axial direction of the material collecting cylinder 50, and the outer end of the connecting rib 60 passes through the through hole five 61 and is connected with the material collecting follower plate 58. The connecting shaft 54 is provided with a mounting hole four for the lead screw 62 to pass through along the axial direction of the connecting shaft 54. The upper end of the lead screw 62 is sleeved with a lead screw nut 63, the outer edge of the lead screw nut 63 is connected with the inner end of the connecting rib 60, the lower end of the lead screw 62 is sleeved with a synchronous belt wheel five 64, and the lower side of the workbench 46 is provided with a material collecting power mechanism three 65. The output end of the material collecting power mechanism three 65 is sleeved with a synchronous belt wheel six 66 corresponding to the synchronous belt wheel five 64, and the synchronous belt wheel five 64 and the synchronous belt wheel six 66 are provided with a belt three therebetween.

[0051] The material collecting power mechanism three 65 is arranged as a motor, and the rotation of the lead screw 62 driven by the material collecting power mechanism three 65 is realized through the transmission of the belt three. Before the material collecting die starts to collect materials, the lead screw 62 rotates, the lead screw nut 63 drives the connecting rib 60 and the material collecting follower plate 58 to move upward in the through hole five 61 along the axial direction of the material collecting cylinder 50, so as to shorten the distance between the winding assembly and the material collecting follower plate 58, and facilitate the stator core punching sheet to fall on the material collecting follower plate 58. During the material collecting process of the material collecting die, as the height of the stator core punching sheet on the material collecting cylinder 50 increases, the lead screw 62 driven by the material collecting power mechanism three 65 rotates in the opposite direction, the lead screw nut 63 drives the connecting rib 60 and the material collecting follower plate 58 to move downward in the through hole five 61 along the axial direction of the material collecting cylinder 50, so as to keep the distance between the winding assembly and the material collecting follower plate 58 consistent, and the stator core punching sheet falls on the material collecting follower plate 58 at a uniform speed.

[0052] As Figure 1 , Figure 13 and Figure 16As shown, the clamping mechanism 9 comprises a mounting plate 68 connected with the output end of the mechanical hand power mechanism 10, the outer edge of the mounting plate 68 is sequentially provided with a clamping jaw 69 and a driving member two 70 for driving the clamping jaw 69 to move along the radial direction of the mounting plate 68 in the circumferential direction of the mounting plate 68, and the driving member two 70 is provided as a pneumatic cylinder. When a set of stator core punching sheet is wound and the material collecting is completed, the material collecting mold mechanism 6 is pushed out by the material collecting power mechanism two 7, the mounting plate 68 is moved to the upper side of the material collecting cylinder 50 under the driving of the mechanical hand power mechanism 10, and the clamping jaw 69 is located at the outer edge of the material collecting cylinder 50, the driving member two 70 drives the clamping jaw 69 to move horizontally, clamps the stator core punching sheet, and moves the stator core punching sheet. The clamping plate 73 at the lower end of the clamping jaw 69, the circumferential direction of the material collecting follower plate 58 is sequentially provided with a groove corresponding to the clamping plate 73, and the clamping plate 73 can be moved to the groove with the clamping jaw 69, which supports the lower end of the stator core punching sheet and prevents the stator core punching sheet from falling off. The mounting plate 68 is provided with a sliding rail two 71 in the driving direction of the driving member two 70, and the upper end of the clamping jaw 69 is provided with a sliding block two 72 which is in sliding fit with the sliding rail two 71, so that the precision of the clamping jaw 69 is improved. The mounting plate 68 is provided with a mounting hole five for the upper end of the supporting rod 74 to pass through in the longitudinal direction, and the mounting hole five is sequentially distributed between the adjacent two clamping jaws 69, and the lower end of the supporting rod 74 is provided with an annular material returning plate 76, which contacts the upper end surface of the stator core punching sheet during the clamping process of the clamping jaw 69, and plays a role of pressing and limiting.

[0053] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above-described embodiments, and those skilled in the art can make some modifications and improvements without departing from the present application, which should be regarded as falling within the protection scope of the present application.
