DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application embodiment discloses a rotor insulation paper automatic embedding device, such as Figure 1 As shown, it includes a frame 1, a propulsion mechanism 2 and a placement mechanism 3. The placement mechanism 3 is used to place the rotor 4 and control the intermittent rotation of the rotor 4; the propulsion mechanism 2 is used to batch produce single-piece insulation paper 12 and embed the insulation paper 12 into the wire slot 41 of the rotor 4 one by one.

[0035] like Figure 1 , 2As shown in Figure 3, the propulsion mechanism 2 includes a molding module 21, a feeding assembly 23 and a die assembly 24. The molding module 21 is fixedly mounted on the frame 1. A molding groove 211 is provided on one side of the molding module 21. The length direction of the molding groove 211 is in the vertical direction. The cross section of the molding groove 211 is consistent with the cross-sectional profile of a single wire slot 41 of the rotor 4. The feeding assembly 23 is used to continuously convey continuous insulating paper 12 to the molding module 21. The die assembly 24 is used to cut the insulating paper 12 into a single piece of insulating paper 12 and press the single piece of insulating paper 12 into the molding groove 211. The feeding assembly 23 includes an unwinding wheel 231 and two escort rollers 232. The unwinding wheel 231 and the escort roller 232 are both rotatably connected to the frame 1 and the rotation axis is in the vertical direction. The two escort rollers 232 are located between the unwinding wheel 231 and the forming module 21. A motor (not shown in the figure) is provided in the frame 1 for driving the escort rollers 232 to rotate. The raw material roll 121 of the insulating paper 12 is placed on the unwinding wheel 231. The insulating paper 12 is wound from the raw material roll 121. The roller surface roughness of the escort roller 232 is relatively high. The two escort rollers 232 respectively abut against the paper surfaces on opposite sides of the insulating paper 12. The escort rollers 232 pull the insulating paper 12 toward the forming module 21 through friction, and then the insulating paper 12 moves to the forming module 21 and then arrives at the notch of the forming groove 211.

[0036] like Figure 2 and 3 As shown, the die assembly 24 includes a die push block 241, a material cutting knife 242, a push rod 243, a push disk 244 and a push motor 245. The die push block 241 is located on the side of the insulating paper 12 away from the forming module 21. The die push block 241 slides relative to the frame 1. The die push block 241 is directly opposite to the notch of the forming groove 211 and the sliding direction is parallel to the depth direction of the forming groove 211. The material cutting knife 242 is integrally formed on the side of the die push block 241 facing the forming module 21 and close to the edge of the escort roller 232. When the die push block 241 moves close to the forming module 21, the blade of the material cutting knife 242 abuts against the side of the insulating paper 12 away from the forming module 21. In cooperation with the forming module 21, the insulating paper 12 is cut off. At the same time, one end of the die push block 241 facing the molding module 21 abuts against the insulating paper 12 and extends into the molding groove 211, and the cut single piece of insulating paper 12 is pushed into the molding groove 211. The propulsion motor 245 is connected to the frame 1, and the propulsion disk 244 is coaxially connected to the output shaft of the propulsion motor 245. One end of the propulsion rod 243 is eccentrically hinged to the propulsion disk 244, and the other end is hinged to the die push block 241, and the hinge axis is perpendicular to the moving direction of the die push block 241. The propulsion disk 244, the propulsion rod 243 and the die push block 241 form a set of crank slider mechanism. After the motor is started, the die push block 241 can move back and forth under the push and pull action of the propulsion rod 243.

[0037] like Figure 1 and4 As shown, the placement mechanism 3 includes a workpiece table 31 and a control component 33. The workpiece table 31 is rotatably connected to the frame 1 and is located above the molding module 21. Its rotation axis is parallel to the length direction of the molding groove 211. The rotor 4 is coaxially placed on the workpiece table 31. The control component 33 is used to control the intermittent rotation of the workpiece table 31. When the workpiece table 31 and the frame 1 are relatively stationary, the molding groove 211 and one of the line grooves 41 of the rotor 4 are aligned, and the notch of the molding groove 211 corresponds to the notch position of the line groove 41; each time the workpiece table 31 rotates, the rotor 4 switches to the adjacent line groove 41 to align with the molding groove 211. The control assembly 33 includes a control gear 331, a control gear ring 332 and a control motor 333. The control motor 333 is fixedly mounted on the frame 1. The control gear 331 is coaxially connected to the output shaft of the control motor 333. The control gear ring 332 is coaxially fixedly connected to the outer edge of the workpiece table 31. The control gear 331 and the control gear ring 332 are meshed. A cylindrical fixed shaft block 312 is coaxially fixedly connected to the workpiece table 31. A synchronous protrusion 313 is fixed to the side wall of the fixed shaft block 312. When the rotor 4 is placed on the workpiece table 31, it is coaxially sleeved outside the fixed shaft block 312. The synchronous protrusion 313 contacts the groove wall at the notch of one of the wire grooves 41 of the rotor 4. With the cooperation of the synchronous protrusion 313 and the wire groove 41, the fixed shaft block 312 limits the synchronous rotation of the rotor 4 relative to the workpiece table 31. The workpiece table 31 is provided with a plurality of clearance holes 311 , which are the same in number and aligned one by one with the wire slots 41 of the rotor 4 , that is, the upper end of the forming groove 211 is aligned and connected with the lower end of one of the clearance holes 311 and one of the wire slots 41 .

[0038] like Figure 2 and 3As shown, the pushing mechanism 2 also includes a paper pusher 22, which is located in the molding groove 211 and slides relative to the molding module 21, and the sliding direction is consistent with the length direction of the molding groove 211. The sliding of the paper pusher 22 is used to push the insulating paper 12 in the molding groove 211 upward. The groove wall of the molding groove 211 is provided with two side wing grooves 212 that are consistent with its own length direction. Both sides of the paper pusher 22 are fixedly connected with side wing blocks 221. A single side wing block 221 is located in a side wing groove 212. When the paper pusher 22 moves upward, the side wing block 221 abuts against the lower edge of the insulating paper 12. The propulsion mechanism 2 also includes a synchronous gear 246, which is rotatably connected to the frame 1; a propulsion rack 247 is fixedly connected to the die push block 241, and the length direction of the propulsion rack 247 is parallel to the moving direction of the die push block 241; a synchronous rack 222 is fixedly connected to the paper pusher 22, and the synchronous rack 222 is parallel to the moving direction of the paper pusher 22, and the synchronous gear 246 is meshed with the synchronous rack 222 and the propulsion rack 247 at the same time. The movement of the die push block 241 and the paper pusher 22 is synchronous: when the die push block 241 moves close to the molding module 21, the paper pusher 22 moves downward, and when the end of the die push block 241 enters the molding groove 211, the paper pusher 22 is located outside the molding groove 211; when the die push block 241 moves away from the molding module 21, the paper pusher 22 moves upward, so that the insulating paper 12 placed in the molding groove 211 can be pushed upward.

[0039] like Figure 1 and 4As shown, when a single wire slot 41 is inserted into the insulating paper 12, the workpiece table 31 rotates to switch to the next wire slot 41. When all the wire slots 41 are embedded in the insulating paper 12, the rotor 4 can be removed from the workpiece table 31. In order to improve the convenience of operation when the staff removes the rotor 4, two auxiliary lifting handles 32 are provided on the workpiece table 31, and the two auxiliary lifting handles 32 are symmetrically arranged relative to the axis of the workpiece table 31. The auxiliary lifting handle 32 is rotatably connected to the workpiece table 31, and the rotation axis is perpendicular to the axis of the workpiece table 31. The auxiliary lifting handle 32 includes a force-bearing portion 321 and a lifting portion 322. The force-bearing portion 321 and the lifting portion 322 are respectively located on both sides of the rotation center of the auxiliary lifting portion 322, and the lifting portion 322 is closer to the axis of the workpiece table 31 relative to the force-bearing portion 321. An auxiliary groove 314 is provided on the surface of the workpiece table 31. When the rotor 4 is placed on the workpiece table 31, the notch of the auxiliary groove 314 is located below the edge of the lower end surface of the rotor 4. An angle is formed between the length direction of the force-bearing portion 321 and the surface of the workpiece table 31. At the same time, the end of the lifting portion 322 away from the force-bearing portion 321 extends into the auxiliary groove 314 and contacts the edge of the lower end surface of the rotor 4. At this time, the auxiliary lifting handle 32 can be regarded as a lever. When all the wire grooves 41 of the rotor 4 are embedded in the insulating paper 12, the operator presses down the force-bearing portions 321 of the two auxiliary lifting handles 32 with both hands. Under the action of the lever, the lifting portion 322 rotates upward to lift the rotor 4, so that a gap is formed between the lower end surface of the rotor 4 and the surface of the workpiece table 31, making it easier for the operator to lift and apply force to the rotor 4.

[0040] like Figure 1 and 5As shown, in order to improve the axial stability of the insulating paper 12 in the wire slot 41, the pushing mechanism 2 includes a bending assembly 25, which is located between the unwinding wheel 231 and the escort roller 232. The bending assembly 25 is used to bend the edge of the insulating paper 12 close to the paper pushing member 22 and the edge away from the paper pushing member 22 to form a folded edge 122. The bending direction of the folded edge 122 relative to the insulating paper 12 is the direction away from the die push block 241, and the angle between the folded edge 122 and the insulating paper 12 is an acute angle. The bending assembly 25 includes a bottom wall plate 251, a card edge block 252 and an adjusting screw 253. The bottom wall plate 251 is fixedly connected to the frame 1. The plate surface of the bottom wall plate 251 is a vertical plane. There are two card edge blocks 252 and both are slidably connected to the frame 1. The two card edge blocks 252 are located on the same side of the bottom wall plate 251 and are arranged up and down. The adjusting screw 253 is rotatably connected to the frame 1. The axis of the adjusting screw 253 is vertical. The adjusting screw 253 is threadedly connected to the two card edge blocks 252 at the same time. When the adjusting screw 253 rotates, the two card edge blocks 252 are controlled to move away from or towards each other. The insulating paper 12 passes between the card edge block 252 and the bottom wall plate 251. The moving direction of the two card edge blocks 252 is the width direction of the insulating paper 12. The edge block 252 is rotatably connected with a bending roller 254, and an angle is formed between the axis of the bending roller 254 and the plate surface of the bottom wall plate 251. At the same time, an acute angle space is formed between the side wall of the bending roller 254 facing the insulating paper 12 and the plate surface of the bottom wall plate 251. When the insulating paper 12 moves to the bending roller 254, its edge is rolled and abutted by the bending roller 254 and bent and deformed to form a folded edge portion 122. The connection between the insulating paper 12 and the folded edge portion 122 is located in the angle space between the side wall of the bending roller 254 and the bottom wall plate 251. When the insulating paper 12 leaves the edge block 252, it is abutted and squeezed by the two escort rollers 232, which improves the stability of the angle shape of the folded edge portion 122 relative to the insulating paper 12.

[0041] like Figure 4 As shown, after the single piece of insulating paper 12 is placed in the forming groove 211, the folded edge portion 122 is located on the side facing the groove wall of the forming groove 211, and the paper pusher 22 abuts against the connection between the lower edge of the insulating paper 12 and the folded edge portion 122. When the insulating paper 12 passes through the clearance hole 311 and is embedded in the wire groove 41, the folded edges 122 on the upper and lower sides are respectively stuck on the two end faces of the rotor 4, so that the resistance of the insulating paper 12 to axial movement relative to the rotor 4 is greatly increased, and the stability of the two is improved.

[0042] The implementation principle of the rotor insulation paper automatic embedding device in the embodiment of the present application is:

[0043] After the rotor 4 is placed on the workpiece table 31, the insulating paper 12 is wound off the unwinding wheel 231, passes through the bending assembly 25 and the escort roller 232 to form the folded edge 122, and then arrives at the molding module 21. Under the action of the die pusher 241 and the material cutter 242, a single piece of insulating paper 12 is formed and pressed into the molding groove 211. The paper pusher 22 slides and pushes the insulating paper 12 in the molding groove 211, so that it passes through the workpiece table 31 and is embedded in the wire groove 41 of the rotor 4. Then the paper pusher 22 moves back, and the embedding of a single insulating paper 12 is completed. The workpiece table 31 rotates to align the adjacent wire groove 41 with the molding groove 211 below, waiting for the embedding of another piece of insulating paper 12, until all wire grooves 41 are embedded with insulating paper 12.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
