The locking block 55 can fix the insert plate 51 so that the arc-shaped plug-in block 41 closes the feeding notch 21. The clamping device 7 is installed on the operating table 1 and is located on one side of the winding wheel 2. The clamping device 7 is used to clamp the motor coil.

[0032] When in use, the clamping device 7 is first opened, and then the feeding gap 21 of the winding wheel 2 is rotated to the side facing the clamping device 7, and then the closed feeding gap 21 is opened. When the feeding gap 21 is closed, the plug plate 51 slides from the winding wheel 2 into the arc-shaped plug block 41, and at the same time the locking block 55 rises from the fixing block 3 and is inserted into the plug plate 51 to fix the plug plate 51 so that the arc-shaped plug block 41 is fixedly connected to the winding wheel 2. When the feeding gap 21 is opened, the locking block 55 is pushed to move toward the center direction of the winding wheel 2. When the locking block 55 is disengaged from the plug plate 51, the plug plate 51 automatically slides toward the lower end of the winding wheel 2 at this time, thereby disconnecting the arc-shaped plug block 41 from the winding wheel 2. After losing the connection with the plug plate 51, the arc-shaped plug block 41 will After the wire is put into the winding wheel 2, the feeding gap 21 is opened, and the plug plate 51 slides to the lower end of the winding wheel 2, the locking block 55 is released.

After fixing the motor coil, the copper wire on the copper wire roller 29 is pulled out, and the copper wire is connected to the motor coil after passing through the fixed block 3, and the driving component 6 is started to make the driving component 6 drive the winding wheel 2 to rotate, thereby starting to wind the motor coil. After completing the winding work of the motor coil, the driving component 6 Stop driving the winding wheel 2 and rotate the winding wheel 2 to make the feeding notch 21 of the winding wheel 2 away from the motor coil, and then push the locking block 55 into the fixed block 3 again to make the plug plate 51 end the connection between the arc plug block 41 and the winding wheel 2, so as to retract the arc plug block 41 and open the feeding notch 21. In the process of retracting the arc plug block 41, the locking block 55 received in the fixed block 3 fixes the copper wire inside it.

[0033] The difference from the above embodiment lies in that a connecting seat 22 is fixedly connected to the inner side of the winding wheel 2, and the connecting seat 22 is located at the upper end of the feeding notch 21; a main spring seat 23 is also fixedly connected to the inner side of the winding wheel 2, and the main spring seat 23 is located above the connecting seat 22; a groove 24 is provided on the outer side of the winding wheel 2, and main connecting grooves 25 are provided on the inner walls on both sides of the groove 24 near the lower end of the feeding notch 21; a driving gear ring 26 is fixedly connected to the side of the winding wheel 2 near the mounting seat 11, and the driving gear ring 26 is rotatably connected to the mounting seat 11, and an equal notch is provided on the side of the driving gear ring 26 corresponding to the feeding notch 21; a connecting plate 27 is fixedly connected in the groove 24, and the connecting plate 27 is located at the lower end of the feeding notch 21; a wire roller groove 28 is provided on the inner side of the winding wheel 2, and the wire roller groove 28 is located at the lower end of the feeding notch 21, and a copper wire roller 29 is rotatably mounted in the wire roller groove 28.

[0034] The copper wire roller 29 is wound with sufficient copper wire for winding the motor coil. After the copper wire on the copper wire roller 29 is used up, the used copper wire roller 29 can be taken out from the wire roller groove 28 and a new copper wire roller 29 can be installed.

[0035] The difference from the above embodiment is that the fixed block 3 is fixedly connected to the inner side of the wire roller groove 28 and is located above the wire roller groove 28. The side of the fixed block 3 facing the center of the winding wheel 2 is a shear surface 31, the shear surface 31 is arc-shaped, and a threading hole 32 is provided on the shear surface 31. A fixed groove 33 is provided in the fixed block 3, and the upper end of the fixed groove 33 passes through the winding wheel 2 and is connected with the groove 24. A sliding groove 34 is provided on one side of the fixed block 3, and the sliding groove 34 is connected with the fixed groove 33, and the lower end of the fixed groove 33 is connected with the threading hole 32.

[0036] When the arc-shaped plug 41 is retracted, the arc-shaped plug 41 with the cutter 45 thereon will cut into the winding wheel 2 along the shear surface 31. When the copper wire is connected to the motor coil, the copper wire must first be passed through the threading hole 32. After the copper wire passes through the threading hole 32, it is connected to the motor coil.

[0037] The difference from the above embodiment is that the diameter of the arc-shaped plug block 41 is equal to the diameter of the winding wheel 2, and the arc-shaped plug block 41 fits with the feeding notch 21, the upper end of the inner side of the arc-shaped plug block 41 is rotatably connected to the connecting seat 22 through a rotating shaft, and an plug block notch 42 is provided on the outer side of the arc-shaped plug block 41, and the plug block notch 42 corresponds to the groove 24, and a secondary connecting groove 421 is provided at the lower end of the plug block notch 42, and the secondary connecting groove 421 corresponds to the main connecting groove 25, and a secondary spring seat 43 is fixedly connected to the inner side of the arc-shaped plug block 41, and the secondary spring seat 43 is rotatably connected to one end of the traction spring 44, and the other end of the traction spring 44 is rotatably connected to the main spring seat 23.

[0038] Among them, when the arc-shaped plug block 41 closes the feeding gap 21, the arc-shaped plug block 41 stretches the traction spring 44. When the plug plate 51 is separated from the arc-shaped plug block 41, the stretched traction spring 44 recovers its deformation, thereby pulling the arc-shaped plug block 41 into the winding wheel 2, retracting the arc-shaped plug block 41, and thus opening the closed feeding gap 21. When the arc-shaped plug block 41 is pulled outward from the winding wheel 2 to close the feeding gap 21 again, the traction spring 44 is stretched again.

[0040] Among them, when the worker's hand approaches the cutter 45, the protective block 46 can prevent the worker's hand from accidentally touching the cutter 45 and causing injury. When the arc-shaped plug block 41 closes the feeding gap 21, the plug slot 42 on the arc-shaped plug block 41 docks with the groove 24, and the arc-shaped gear ring 47 docks with the drive gear ring 26, so that the winding wheel 2 and the drive gear ring 26 form a complete closed loop, ensuring the stable operation of the winding wheel 2 during winding.

[0041] The difference from the above embodiment is that the plug plate 51 is arc-shaped and fits with the groove 24, and the plug plate 51 is slidably installed in the main connecting groove 25, and the end of the plug plate 51 away from the arc-shaped plug block 41 is fixedly connected with a fixing plate 52, and an arc spring 53 is fixedly connected between the fixing plate 52 and the connecting plate 27. A locking groove 54 is opened on the plug plate 51. When the plug plate 51 is slidably inserted into the secondary connecting groove 421, the locking groove 54 corresponds to the fixing groove 33.

[0042] When the plug plate 51 is pushed from the main connecting groove 25 into the auxiliary connecting groove 421, the plug plate 51 stretches the arc spring 53. At the same time, the sliding plug plate 51 will press the protruding end of the locking block 55 into the fixed groove 33. When the plug plate 51 completes the connection between the winding wheel 2 and the arc plug block 41, the locking groove 54 is opposite to the fixed groove 33, and the locking block 55 pops out from the fixed groove 33 and is inserted into the locking groove 54, thereby fixing the plug plate 51. When it is necessary to open the closed feeding gap 21, the locking block 55 is pushed into the fixed groove 33 to end the fixing of the locking block 55 to the plug plate 51. The stretched arc spring 53 recovers its deformation, and the plug plate 51 is pulled out of the auxiliary connecting groove 421, so that the arc plug block 41 is retracted.

[0043] The difference from the above embodiment is that the locking block 55 is slidably installed in the fixed groove 33, and a locking spring 56 is fixedly connected between the lower side of the locking block 55 and the inner wall of the fixed groove 33. The locking spring 56 can push the upper end of the locking block 55 to slide out of the fixed groove 33. The lower end of the locking block 55 is fixedly connected to a pin 57, and the pin 57 corresponds to the threading hole 32. A pull rod 58 is fixedly connected to one side of the locking block 55, and one end of the pull rod 58 extends out from the sliding groove 34.

[0044] When the fixing of the plug plate 51 needs to be released, the locking block 55 is pulled toward the shear surface 31 by the pull rod 58, so that the locking block 55 is retracted into the fixing groove 33 and the locking spring 56 is compressed. At the same time, the ejector pin 57 at the lower end of the locking block 55 is inserted into the threading hole 32 to fix the copper wire in the threading hole 32, so that the copper wire can be cut by the cutter 45 when the arc-shaped plug block 41 is retracted. After the pull rod 58 is released, the compressed locking spring 56 recovers its deformation, thereby locking the locking block 55. 55 is pushed out from the fixing groove 33, and the ejector pin 57 at the lower end of the locking block 55 leaves the threading hole 32, ending the fixation of the copper wire therein. When the plug board 51 is inserted into the secondary connecting groove 421, the inserted end of the plug board 51 presses the protruding end of the locking block 55 into the fixing groove 33 and compresses the locking spring 56. When the locking groove 54 is aligned with the fixing groove 33, the compressed locking spring 56 recovers its deformation, thereby pushing the locking block 55 into the locking groove 54 to fix the plug board 51.

[0045] The difference from the above-mentioned embodiment lies in that a plurality of rollers 111 are rotatably mounted on the mounting seat 11, the rollers 111 are closely attached to the outer side of the winding wheel 2, a driving groove 12 is provided at the bottom of the mounting seat 11, a control panel 13 is rotatably mounted on the operating table 1, the control panel 13 is located on one side of the mounting seat 11, and the control panel 13 controls the movement of the driving component 6 through the PLC program.

[0046] When winding the motor coil, the corresponding data can be set through the control panel 13, so that the driving component 6 drives the winding wheel 2 to wind the motor coil. During the rotation of the winding wheel 2, the roller 111 can assist the winding wheel 2 to rotate more smoothly.

[0047] The difference from the above embodiment is that the driving assembly 6 includes a driving motor 61 and a handwheel 64.

A handwheel 64 is coaxially fixedly connected to the extended end of the output shaft of the driving motor 61.

[0048] Among them, when the driving component 6 is started, the driving motor 61 drives the driving gear 62 and the hand wheel 64 on its output shaft to rotate, and the rotating driving gear 62 drives the driving gear ring 26 to rotate through the transmission gear 63, thereby rotating the winding wheel 2. When the driving component 6 is not started and the winding wheel 2 needs to be rotated, the driving gear 62 is rotated by rotating the hand wheel 64 to rotate the winding wheel 2.

[0049] The difference from the above-mentioned embodiment is that a coil winding method for manufacturing an electric motor uses the coil winding device described above.

[0050] Working principle: When in use, first open the clamping device 7, then the hand wheel 64 rotates the feeding gap 21 of the winding wheel 2 to the side facing the clamping device 7, and then the closed feeding gap 21 is opened, wherein, when the feeding gap 21 is closed, the arc plug block 41 stretches the traction spring 44, and the plug plate 51 slides from the winding wheel 2 into the arc plug block 41, stretching the arc spring 53, and at the same time the locking block 55 rises from the fixing block 3 and is inserted into the plug plate 51, fixing the plug plate 51, so that the arc plug block 41 is fixedly connected to the winding wheel 2, and when the feeding gap 21 is opened, the locking block 55 is pulled toward the shear surface 31 by the pull rod 58, so that the locking block 55 is retracted into the fixing groove 33 and the locking spring 56 is compressed. When the locking block 55 is separated from the plug plate 51 When the arc plug 41 loses the connection with the plug plate 51, the stretched arc spring 53 recovers its deformation, and the plug plate 51 is pulled out from the auxiliary connecting groove 421. The stretched traction spring 44 recovers its deformation, and the arc plug 41 is pulled into the winding wheel 2, and the arc plug 41 is retracted to open the feeding notch 21. After the plug plate 51 slides to the lower end of the winding wheel 2, the locking block 55 is released, and the compressed locking spring 56 recovers its deformation, so that the locking block 55 is pushed out from the fixing groove 33 and extends from the fixing block 3 to the winding wheel 2 again. When the arc plug 41 is retracted, the cutter 45 on the arc plug 41 will pass through the fixing block 3.

[0051] After opening the feeding gap 21, the motor coil to be wound is placed into the feeding gap 21, and the winding wheel 2 passes through the motor coil. Then, the winding wheel 2 is rotated to make the feeding gap 21 of the winding wheel 2 away from the motor coil, and then the arc plug block 41 is pulled outward to make the arc plug block 41 close the feeding gap 21 again. The traction spring 44 is stretched again. After closing the feeding gap 21, the plug plate 51 is pushed to move in the direction of the arc plug block 41, and the arc plug block 41 and the winding wheel 2 are connected again through the plug plate 51. In this process, the plug plate 51 will The locking block 55 on the winding wheel 2 is pressed into the fixing block 3. When the plug plate 51 connects the arc plug block 41 and the winding wheel 2, the pressed locking block 55 pops out to lock the plug plate 51, thereby fixing the arc plug block 41 on the winding wheel 2, so that the feeding gap 21 is closed by the arc plug plate 51. Then the clamping device 7 is controlled to clamp and fix the motor coil. After the motor coil is fixed, the copper wire on the copper wire roller 29 is pulled out and the copper wire is passed through the threading hole 32. After the copper wire passes through the threading hole 32, it is connected to the motor coil and the driving component 6 is started. , the driving motor 61 drives the driving gear 62 and the hand wheel 64 on its output shaft to rotate, and the rotating driving gear 62 drives the driving gear ring 26 to rotate through the transmission gear 63, so that the winding wheel 2 rotates to wind the motor coil. After completing the winding work of the motor coil, the driving component 6 stops driving the winding wheel 2 and rotates the winding wheel 2. After the feeding notch 21 of the winding wheel 2 is away from the motor coil, the locking block 55 is pushed into the fixing block 3 again, so that the plug plate 51 ends the connection between the arc plug block 41 and the winding wheel 2, thereby retracting the arc Insert block 41 to open the feeding gap 21. In the process of retracting the arc-shaped plug block 41, the ejector pin 57 at the lower end of the locking block 55 is inserted into the threading hole 32 to fix the copper wire in the threading hole 32. When the arc-shaped plug block 41 is retracted, the cutter 45 thereon passes over the fixing block 3 to cut off the copper wire connected to the motor coil. Then, the feeding gap 21 is turned to the position of the motor coil by the hand wheel 64, and the clamping device 7 is opened to take out the motor coil that has been wound, and put in the next motor coil to be wound, and then repeat the above steps for production.
