These waste wire ends are not only troublesome to handle and collect, but also cause the loss of copper wire, resulting in unnecessary waste. Utility Model Content

[0003] The main purpose of the utility model is to provide a stator winding machine, aiming to solve the problem of waste wire ends generated during the winding process and reduce copper wire loss.

[0041] In which, the clamping assembly includes two spaced-apart manipulators, and the direction of the spacing between the two manipulators is the direction of the line between the conveying mechanism and the supporting mechanism. The seventh drive assembly drives the manipulator close to the conveying mechanism to clamp the product on the tray, and drives the clamping assembly to move toward the supporting mechanism, so that the product close to the supporting mechanism clamps the stator wound on the supporting mechanism, and places the product clamped by the manipulator close to the conveying mechanism on the supporting mechanism.

[0042] In the technical solution of the present invention, a supporting mechanism, a limiting mechanism and a main shaft mechanism are arranged on the frame, the supporting mechanism supports the product, the main shaft mechanism winds the product on the frame, and the limiting mechanism covers the upper end of the product, which can prevent the copper wire from hanging on the upper end of the product during winding, thereby interfering with the copper wire and affecting the winding progress and quality. The shearing mechanism includes a clamping component and a shearing component. Driven by the first driving component, the clamping component first clamps the copper wire and approaches the product before the main shaft mechanism winds the product, so that the main shaft mechanism can use force to wind the product. During the winding process, the first driving component drives the clamping component The copper wire is released, and the head end of the copper wire is wound on the product. When the winding is about to be completed, the first drive component drives the clamping component to clamp the copper wire, and drives the cutting component to cut the clamped copper wire. At this time, the disconnection point of the coil wound on the product is used as the wire tail. The product with completed winding on the supporting mechanism is taken away, and a new product is put in. After cutting, one end of the copper wire clamped by the clamping component is used as the head end of the winding of the product. Repeat the above process to complete the winding of multiple products. By setting up the shearing and clamping mechanism, there is no need to wrap the head end of the copper wire on the positioning structure before winding, which avoids the generation of wire ends and reduces the loss of copper wire.

[0071] A stator winding machine is a mechanical device specially used to wind coils on the stators of equipment such as motors and generators. Copper wire is usually used for winding. Many existing winding machines will produce waste wire ends after winding is completed, such as the wire ends produced after the head and tail ends of the coil are cut off. These waste wire ends are not only troublesome to handle and collect, but also cause the loss of copper wire, resulting in unnecessary waste.

[0072] The utility model provides a stator winding machine.

[0073] See also Figure 2 and Figure 5 In one embodiment of the present invention, the stator winding machine comprises:

[0074] Rack 100;

[0075] The supporting mechanism 200 is provided on the frame 100 and is used to support the product and drive the product to rotate;

[0076] The limiting mechanism 300 is provided on the frame 100 and is used to cover the upper end of the product;

[0077] A spindle mechanism 400 is provided on the frame 100 and is used to wind the product supported by the supporting mechanism 200; and

[0078] The shearing and clamping mechanism 500 is provided on the frame 100. The shearing and clamping mechanism 500 includes a first driving assembly 510, a clamping assembly 520 and a shearing assembly 530. The first driving assembly 510 drives and connects the clamping assembly 520 and the shearing assembly 530.

[0079] Among them, the first driving component 510 drives the clamping component 520 to clamp the tail end of the copper wire after the product winding is completed, and drives the cutting component 530 to cut the copper wire, so that the end of the copper wire clamped by the clamping component 520 serves as the starting end of the next product winding.

[0080] In the technical solution of this utility model, please refer to Figure 2 By arranging a supporting mechanism 200, a limiting mechanism 300 and a spindle mechanism 400 on the frame 100, the supporting mechanism 200 supports the product, the spindle mechanism 400 winds the product on the frame 100, and the limiting mechanism 300 covers the upper end of the product, which can prevent the copper wire from hanging on the upper end of the product during winding, thereby interfering with the copper wire and affecting the winding progress and quality. The shearing mechanism 500 includes a clamping component 520 and a shearing component 530. Driven by the first driving component 510, the clamping component 520 first clamps the copper wire and approaches the product before the spindle mechanism 400 winds the product, so that the spindle mechanism 400 can use force to wind the product. During the winding process, the first driving component 5 10 drives the clamping component 520 to release the copper wire. At this time, the head end of the copper wire is wound on the product. When the winding is about to be completed, the first driving component 510 drives the clamping component 520 to clamp the copper wire and drives the cutting component 530 to cut the clamped copper wire. At this time, the disconnection point of the coil wound on the product is used as the wire tail. The product with completed winding on the supporting mechanism 200 is taken away and a new product is put in. After cutting, one end of the copper wire clamped by the clamping component 520 is used as the head end of the winding of the product. Repeat the above process to complete the winding of multiple products. By setting the cutting and clamping mechanism 500, there is no need to wrap the head end of the copper wire on the positioning structure before winding, which avoids the generation of wire ends and reduces the loss of copper wire.

[0081] The product may be the stator 120, but is not limited to the stator 120. In this embodiment, the product is the stator 120, and the following products are all referred to as the stator 120. Please refer to Figure 11The supporting mechanism 200 includes a mounting plate 210, a supporting seat 220 is provided above the mounting plate 210, and the supporting seat 220 is used to support the product (stator 120). A motor is provided below the mounting plate 210, and the output shaft of the motor passes through the mounting plate 210 to drive the connection supporting seat 220 and drive the supporting seat 220 to rotate, so that after the stator 120 winds one core, the stator 120 is driven to rotate and the next core is wound. In addition, the mounting plate 210 is connected to the frame 10 through a linear drive structure. 0, when a new stator 120 is placed on the supporting seat 220, the linear drive structure drives the mounting plate 210 to move to the bottom of the limiting mechanism 300, and the limiting mechanism 300 covers the upper end of the stator 120. Winding is performed through the spindle mechanism 400. After the winding is completed, the limiting mechanism 300 releases the stator 120, and the mounting plate 210 slides away from the limiting mechanism 300 to remove the stator 120 and place a new stator 120. The linear drive mechanism can be a structure such as a cylinder, a hydraulic cylinder or an electric telescopic cylinder.

[0082] Please refer to Figure 1 A cover 110 is provided above the frame 100 to cover the supporting mechanism 200, the limiting mechanism 300, the spindle mechanism 400 and the shearing mechanism 500 on the frame 100, so as to prevent dust from falling on the mechanisms after long-term work and affecting the work.

[0083] In addition, the number of the supporting mechanism 200, the limiting mechanism 300 and the main shaft mechanism 400 is the same. In this embodiment, two supporting mechanisms 200, two limiting mechanisms 300 and two main shaft mechanisms 400 are each provided, and are arranged correspondingly, so as to facilitate winding of two stators 120 at the same time and improve efficiency.

[0084] The stator winding machine of this solution also includes a wire barrel 800 and a tensioner 810. Copper wire is wound in the wire barrel 800. After the copper wire passes through the wire barrel 800, the tension of the copper wire is adjusted by the tensioner 810, and then reaches the main shaft mechanism 400. The winding of the stator 120 is completed through the main shaft mechanism 400.

[0085] In an embodiment of the present invention, the first drive assembly 510 has a fixed end and a drive end, and the shearing and clamping mechanism 500 further includes:

[0086] A mounting base 540 is mounted on the fixed end, and the clamping assembly 520 is rotatably mounted on the mounting base 540;

[0087] The fixing base 550 is mounted on an end of the mounting base 540 away from the first driving assembly 510;

[0088] The push plate 560 is slidably mounted on the mounting seat 540 , and the driving end is drivingly connected to the push plate 560 and the shearing assembly 530 to drive the push plate 560 and the shearing assembly 530 to move along the length direction of the mounting seat 540 ;

[0089] Among them, the end of the push plate 560 away from the driving end is driven and connected to the clamping assembly 520, so that the clamping assembly 520 has a first state and a second state. In the first state, the push plate 560 moves toward the fixed seat 550 and abuts against one end of the clamping assembly 520 to drive the clamping assembly 520 to rotate, so that the other end of the clamping assembly 520 rotates toward the fixed seat 550, and the clamping assembly 520 and the fixed seat 550 cooperate to clamp the copper wire. In the second state, the push plate 560 moves in a direction away from the fixed seat 550 to release the clamping assembly 520, and the end of the clamping assembly 520 close to the fixed seat 550 rotates in a direction away from the fixed seat 550 to release the copper wire.

[0090] Please refer to Figure 6 and Figure 7 The first drive assembly 510 adopts a linear drive structure, such as a pneumatic cylinder, a hydraulic cylinder or an electric telescopic cylinder. In this embodiment, it is a pneumatic cylinder, whose fixed end is the cylinder body and the driving end is the piston rod. Specifically, the mounting seat 540 is fixed on the cylinder body, and the extension direction of the mounting seat 540 is the extension direction of the piston rod. A fixed seat 550 is fixedly installed at the end of the mounting seat 540 away from the cylinder body. The limit seat 570 cooperates with the clamping assembly 520 to complete the clamping of the copper wire, and then cooperates with the shearing assembly 530 to cut the copper wire. Among them, the clamping assembly 520 includes a clamping rod 521 and a push rod 522. The push rod 522 is fixedly connected to the clamping rod 521, and the clamping rod 521 is close to the fixed seat 550. The push rod 522 is rotatably connected to the mounting seat 540 through a rotating shaft and is close to the first drive assembly 510. The output end of the piston rod drives the push plate 560 to move toward the fixed seat 550, so that the push plate 560 is close to the When the cam 521 is in the closed position, the push rod 522 is in the closed position, and the push rod 522 is in the closed position, so that the cam 521 is in the closed position, and the push rod 522 is in the closed position, so that the cam 521 is in the closed position, and the push rod 522 is in the closed position, so that the cam 521 is in the closed position, and the push rod 522 is in the closed position, so that the cam 521 is in the closed position, and the push rod 522 is in the closed position, so that the cam 521 is in the closed position, and the push rod 522 is in the closed position, so that the cam 521 is in the closed position,

[0091] Please refer to Figure 8A stopper 551 is provided at one end of the fixing seat 550 away from the mounting seat 540. The stopper 551 extends upward. When the copper wire needs to be clamped, the fixing seat 550 is moved to a position where the copper wire is placed on the fixing seat 550. The setting of the stopper 551 can prevent the copper wire from slipping off the end of the fixing seat 550.

[0092] In a preferred embodiment, please refer to Figure 7 A first inclined surface 561 is provided on the upper part of the end of the push plate 560 away from the first driving assembly 510, and a second inclined surface 5221 is provided on the opposite end of the push rod 522 away from the clamping rod 521. The slope of the first inclined surface 561 and the second inclined surface 5221 are the same. On the first inclined surface 561, the end close to the first driving assembly 510 is higher than the end away from the first driving assembly 510. On the second inclined surface 5221, the end away from the fixed seat 550 is higher than the end close to the fixed seat 550. In this way, when the push plate 560 moves toward the fixed seat 550, the first inclined surface 561 cooperates with the second inclined surface 5221 to make the push rod 522 rotate upward.

[0093] In addition, please refer to Figure 7 The piston rod is also driven and connected to the shearing assembly 530. When in the first state, the piston rod moves toward the fixed seat 550, which not only makes the clamping assembly 520 and the fixed seat 550 clamp the copper wire, but also pushes the shearing assembly 530 to move toward the fixed seat 550, so that the shearing assembly 530 cuts off the clamped copper wire. Among them, the end of the shearing assembly 530 close to the fixed seat 550 is an inclined surface, which reduces the contact area with the copper wire and facilitates cutting the copper wire. It should also be noted that the shearing assembly 530 and the clamping assembly 520 are located on opposite sides of the mounting seat 540 to facilitate the rotation of the clamping assembly 520 and the horizontal movement of the shearing assembly 530.

[0094] In an embodiment of the present invention, the shearing and clamping mechanism 500 also includes a limit seat 570 and an elastic member. The limit seat 570 is fixed to the mounting seat 540, and the elastic member is used to connect the end of the clamping assembly 520 away from the fixed seat 550 with the limit seat 570. In the first state, the end of the clamping assembly 520 away from the fixed seat 550 rotates toward the limit seat 570 to compress the elastic member. In the second state, the elastic member drives the end of the clamping assembly 520 away from the fixed seat 550 to rotate in a direction away from the limit seat 570, so that the end of the clamping assembly 520 close to the fixed seat 550 rotates in a direction away from the fixed seat 550.

[0095] Please refer to Figure 7, the limiting seat 570 is fixed on the mounting seat 540. In this embodiment, it is installed on the side of the mounting seat 540 where the clamping rod 521 is set. The upper end of the limiting seat 570 is located above the mounting seat 540 and is bent toward the mounting seat 540. An elastic member (not shown) is provided between the upper seat of the limiting seat 570 and the mounting seat 540. The elastic member can be a spring, plastic or other structure with elasticity, preferably a spring with greater elasticity. When in the first state, the push plate 560 moves toward the fixed seat 550 to drive the push rod 522 to rotate, and the push rod 522 rotates in the direction away from the fixed seat 550, that is, rotates upward. It can be understood that during the rotation of the push rod 522, it cooperates with the limit seat 570 to compress the elastic member. At this time, the clamping rod 521 rotates toward the fixed seat 550 to clamp the copper wire. When clamping is not needed, the push plate 560 moves in the direction away from the fixed seat 550, releasing the push rod 522. The elastic member rebounds and drives the push rod 522 to rotate in the direction of the mounting seat 540, that is, rotates in the direction away from the limit seat 570, completing the reset of the clamping assembly 520.

[0096] In an embodiment of the present invention, the end of the product has a hook 121, and the limiting mechanism 300 includes:

[0097] A stand 310 is provided on the frame 100;

[0098] The second driving assembly 320 is provided on the stand 310;

[0099] The middle cover assembly 330 is drivingly connected to the second driving assembly 320 , and the second driving assembly 320 drives the middle cover assembly 330 to rise and fall in the vertical direction, so that the middle cover assembly 330 covers the hook 121 of the product on the supporting mechanism 200 .

[0100] Please refer to Figure 3 There is a hook 121 at the upper end of the stator 120. When winding, the copper wire is easily hung on the hook 121, affecting the winding quality. Therefore, a limiting mechanism 300 is set. The specific limiting mechanism 300 includes a stand 310 and a middle sleeve assembly 330. The stand 310 is set on the frame 100. The second drive assembly 320 drives the middle sleeve assembly 330 to descend by adopting a linear drive structure such as a cylinder. The middle sleeve assembly 330 includes a sleeve and a pressure shaft. The pressure shaft is set on the inner ring of the sleeve. The second drive assembly 320 drives the sleeve and the pressure shaft to rise and fall at the same time. In addition, the pressure shaft is pressed on the upper end of the stator 120 and cooperates with the hook 121 on the stator 120.

[0113] In an embodiment of the present invention, the stator winding machine further includes a conveying mechanism 600, which includes:

[0114] The feeding conveyor line 610 is provided on the frame 100;

[0115] The tray 630 is provided on the feeding conveyor line 610 and moves along the length direction of the feeding conveyor line 610. The tray 630 is used to carry products;

[0116] The first sensor 640 is provided on the feeding conveyor line 610 and is used to sense the tray 630;

[0117] The lifting assembly 650 is provided on the feeding conveyor line 610 to lift the tray 630 when the first sensor 640 senses the tray 630 .

[0118] Please refer to Figure 12 A continuously running feeding conveyor line 610 is provided on the frame 100, and a tray 630 is placed on the feeding conveyor line 610. The tray 630 moves with the operation of the feeding conveyor line 610. The first sensor 640 is on the feeding conveyor line 610. When it senses the arrival of the tray 630, the tray 630 is lifted to the top of the feeding conveyor line 610 by the lifting assembly 650 to wait for the stator 120 on the tray 630 to be removed and a new stator 120 to be placed. After the new stator 120 is placed, the lifting assembly 650 descends, and the tray 630 descends together with the lifting assembly 650. Specifically, on the feeding conveyor line 610, A support base 670 is fixedly set on the top, and the support base 670 includes a side plate, a top plate and a bottom plate. The bottom plate is located below the feeding conveyor line 610, and the top plate is located above the bottom plate. The side plates connect the top plate and the bottom plate and are fixed on the frame of the feeding conveyor line 610. The first sensor 640 is installed on the side plate, and the sensing end is facing the feeding conveyor line 610. The lifting assembly 650 includes a linear drive structure, which can adopt a cylinder, a hydraulic cylinder or an electric telescopic rod, which is fixed on the bottom plate, and the output end passes through the feeding conveyor line 610 upward and lifts the tray 630, wherein a positioning column is provided on the upper surface of the tray 630 to limit the stator 120.

[0119] In addition, please refer to Figure 12 The conveying mechanism 600 also includes a return conveyor line 620 parallel to the feeding conveyor line 610. The return conveyor line 620 has a transportation direction opposite to that of the feeding conveyor line 610. The feeding conveyor line 610 conveys the unwound stator 120 along with the tray 630 to the jacking assembly 650. After the winding is completed, the wound stator 120 is placed back on the tray 630 and transported to the next process along the feeding conveyor line 610. When the last process is completed, the stator 120 on the tray 630 is removed, and the empty tray 630 is transferred to the return conveyor line 620, and moved to the first process along with the operation of the return conveyor line 620, thereby realizing the recycling of the tray 630.

[0120] In an embodiment of the present invention, the conveying mechanism 600 further includes a positioning assembly 660 , which is disposed above the feeding conveyor line 610 and corresponds to the lifting assembly 650 to position the tray 630 when the lifting assembly 650 lifts the tray 630 .

[0121] Please refer to Figure 13 , a positioning assembly 660 is set above the support seat 670, and an opening is set on the top plate to facilitate the lifting assembly 650 to lift the tray 630 through the opening. A positioning assembly 660 is set on both sides of the opening. The positioning assembly 660 includes a linear drive structure. The linear drive structure can adopt a positioning cylinder, whose output end faces the opening and is connected to a positioning plate. The end of the positioning plate away from the positioning cylinder is provided with a positioning column. Correspondingly, a positioning block is provided above the tray 630, and a positioning groove is provided on the positioning block. When the lifting assembly 650 lifts the tray 630 30 is lifted and passes through the opening, the piston rod of the positioning cylinder extends out and abuts against the positioning groove, positioning the tray 630 above the support seat 670. In order to improve the efficiency of winding, a plurality of stator winding machines are usually arranged at intervals along the conveying direction of the feeding conveyor line 610. Therefore, when the lifting component 650 in this embodiment lifts the tray 630 and fixes the tray 630 through the positioning component 660, the lifting component 650 descends so that the other trays 630 carrying the stators 120 on the feeding conveyor line 610 move to the next support seat 670 and wait for lifting.

[0122] In an embodiment of the present invention, the conveying mechanism 600 further includes a second sensor 641 . The second sensor 641 is disposed on the feeding conveyor line 610 to sense whether the tray 630 passing through the positioning assembly 660 carries products.

[0123] Please refer to Figure 13 A second sensor 641 is provided on the side panel. The tray 630 first passes through the first sensor 640 and then the second sensor 641 on the feeding conveyor line 610. The second sensor 641 detects whether a stator 120 is placed on the tray 630. If the second sensor 641 detects that a stator 120 is placed on the tray 630, the tray 630 is lifted upward by the lifting assembly 650 to wait for the stator 120 to be removed and the unwound stator 120 to be placed.

[0124] In an embodiment of the present invention, the stator winding machine further includes a transport mechanism 700, which includes:

[0125] The mounting frame 710 is provided on the frame 100;

[0126] A clamping assembly 720 is provided on the mounting frame 710 and is used to clamp products;

[0127] a seventh driving assembly, disposed on the mounting base 540 , drivingly connecting the clamping assembly 720 to drive the clamping assembly 720 to move along the fourth direction and the fifth direction;

[0128] Among them, the clamping component 720 includes two spaced-apart manipulators 721, and the direction of the spacing between the two manipulators 721 is the direction of the line between the conveying mechanism 600 and the supporting mechanism 200. The seventh driving component drives the manipulator 721 close to the conveying mechanism 600 to clamp the product on the tray 630, and drives the clamping component 720 to move toward the supporting mechanism 200, so that the product close to the supporting mechanism 200 clamps the stator 120 wound on the supporting mechanism 200, and places the product clamped by the manipulator 721 close to the conveying mechanism 600 on the supporting mechanism 200.

[0129] Please refer to Figure 14 The conveying mechanism 700 is used to transport the stator 120 between the conveying mechanism 600 and the supporting mechanism 200. Specifically, a mounting frame 710 is provided on the frame 100, and a seventh driving assembly is provided on the mounting frame 710 to drive the clamping assembly 720 to move. The seventh driving assembly includes a lifting cylinder, which drives the clamping assembly 720 to move along the fourth direction, which is lifted and lowered in the vertical direction in this embodiment. Specifically, a spring is further provided between the output end of the lifting cylinder and the clamping assembly 720 to facilitate the lifting of the clamping assembly 720 when the lifting cylinder drives the clamping assembly 720 to descend and clamp the stator 120. The spring provides a buffer to avoid the clamping assembly 720 from moving downward and causing a collision with the stator 120, thereby affecting the quality. In addition, the seventh driving assembly also includes a motor and a transmission belt. The lifting cylinder is installed on the transmission belt through a mounting portion to drive the clamping assembly 720 to move along the fifth direction. In this embodiment, the fifth direction is the direction between the conveying mechanism 600 and the supporting mechanism 200.

[0130] Specifically, the clamping assembly 720 can adopt a three-claw clamp, which is driven by a cylinder to clamp the outer periphery of the stator 120, so as to avoid damage to the stator 120. The clamping assembly 720 includes two manipulators 721. It can be understood that each manipulator 721 corresponds to a lifting cylinder and a spring, and the lifting cylinders on the same side are installed on a mounting portion. The spacing direction of the two manipulators 721 is the same as the fifth direction, so that the two manipulators 721 can respectively clamp the unwound stator 120 and the wound stator 120. For example, the seventh drive assembly drives the clamping assembly 720 to move toward the supporting mechanism 200, and drives the manipulator 721 close to the supporting mechanism 200 to clamp the wound stator 120 on the supporting mechanism 200 and move toward the conveying mechanism 600. When the manipulator 721 close to the conveying mechanism 600 reaches above the feeding conveyor line 610, the manipulator 721 clamps the tray 63 0, and continues to move in this direction until the manipulator 721 close to the supporting mechanism 200 moves above the empty tray 630, at which time it places the wound stator 120 on the empty tray 630, completing the replacement of the stator 120 on the tray 630, and the seventh drive component drives the clamping component 720 to move toward the supporting mechanism 200, and the manipulator 721 close to the supporting mechanism 200 is an empty manipulator 721 at this time. When it reaches above the supporting mechanism 200, it clamps the wound stator 120 on the supporting mechanism 200, and the seventh drive component drives the clamping component 720 to continue moving until the manipulator 721 close to the conveying mechanism 600 moves above the supporting mechanism 200, and places the clamped unwound stator 120 on the supporting mechanism 200, completing the removal of the wound stator 120 from the supporting mechanism 200 and the placement of the unwound stator 120.

[0131] Please note that, please refer to Figure 2 In order to improve the processing efficiency of the product, at least one supporting mechanism 200, a spindle mechanism 400 and a shearing and clamping mechanism 500 can be set on each frame 100. For reference, in this embodiment, a clamping assembly 720 is set on both sides of the mounting frame 710, and two supporting mechanisms 200, two limiting mechanisms 300, two spindle mechanisms 400 and two shearing and clamping mechanisms 500 are correspondingly set on the frame 100, and two support seats 670 are correspondingly set on the feeding conveyor line 610. A lifting assembly 650, a first sensor 640, a second sensor 641 and a positioning assembly 660 are correspondingly set on each support seat 670 so that the two clamping assemblies 720 can work simultaneously.
