Description

Technical Field

[0001] This invention belongs to the field of motor stator winding technology, specifically an automotive motor stator winding machine. Background Technology

[0002] With the rapid development of new energy vehicles, the car motor, as the power source that drives the car, plays a very important role in the entire car system. In the production process of the car motor, it is necessary to wind the stator coil of the car motor. Although the winding process is tedious, it is a very important step.

[0003] A patent with publication number CN117639414B discloses an automotive motor coil winding machine. This device, through the cooperation of a housing, a reel, and a winding mechanism, utilizes a traction device that rotates in a first direction to drive the wire to rotate synchronously and wind the winding terminal. Each rotation of the traction device around the first direction completes one revolution of the winding terminal. Furthermore, by moving the traction device along the first direction, the winding position of the wire in that direction can be changed. That is, after the traction device has driven the wire to complete one revolution around the winding terminal in the first direction, the traction device moves from the first... One end moves along the first direction toward the second end of the winding terminal, and then the traction device drives the wire to rotate around the first direction. This cycle is repeated until the winding of one winding terminal is completed. After the traction device finishes winding one winding terminal, the stator coil and the housing rotate relative to each other, so that the traction device moves to the position of another winding terminal and can continue winding. By repeating the above actions, the winding of all winding terminals can be achieved. All winding work of the winding terminals is done using only a single traction device, which is simple in structure, convenient in winding, and avoids improper winding during the winding process.

[0004] The above-mentioned solution still has some problems in practical application. Usually, the stator is first put on the fixed plug, and then the electric push rod drives the pressing column to press it from the top. Then the winding mechanism and the clamping mechanism work together to complete the copper wire clamping and winding operation. However, this fixing method has two major drawbacks: First, the plug diameter is fixed. When facing stators of different specifications, if the inner diameter of the stator is too large, the radial gap between the plug and the inner cavity of the stator is too large, and the stator is very easy to shake during the winding process, resulting in a decrease in winding accuracy. Conversely, if the inner diameter of the stator is too small, it cannot be put on the plug smoothly, causing clamping difficulties. Second, the additional pressing column, electric push rod and other components further increase the equipment cost and maintenance complexity, which seriously restricts the flexible winding efficiency of stators of multiple varieties and small batches.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The stator winding machine for an automotive motor of the present invention involves installing the stator outside a fixed cylinder, and pressing a clamping plate to drive a push rod. The push rod then pushes a sliding plate to press a first spring closer together, causing the clamping plate to slide into the inner cavity of a cross groove, allowing the stator to slide outside the fixed cylinder. The first spring then lifts the sliding plate, causing it to drive the push rod to expand the clamping plate, thus clamping and fixing the stator from within the cavity. An external clamping mechanism then clamps and fixes the copper wire end. Finally, a geared disc is driven to rotate, causing the geared disc to... The meshing drive gear ring rotates, which in turn drives the winding frame to rotate synchronously. The winding frame then uses the guide tube to drive the copper wire to rotate, thus winding the copper wire around the stator. This avoids the problem of existing winding machines using pins to fix the stator. Because the pin diameter is fixed, when dealing with stators of different specifications, if the stator inner diameter is too large, the radial gap between the pin and the stator inner cavity is too large, and the stator is prone to shaking during the winding process, resulting in a decrease in winding accuracy. Conversely, if the stator inner diameter is too small, the pin cannot be smoothly inserted, causing clamping difficulties.

[0019] 2. The stator winding machine for an automotive motor described in this invention uses a drive transmission bevel gear assembly and a rotating shaft to drive the driven bevel gear assembly to rotate, which in turn drives the reciprocating screw to rotate. This causes the threaded drive sliding frame to reciprocate within the groove, thus causing the sliding frame to move the winding frame and the wire cylinder back and forth towards and away from the stator. The winding frame and the wire cylinder then rotate to wind the stator teeth. Four rotations of the worm gear cause the threaded drive worm wheel to rotate 30 degrees. After the reciprocating screw rotates four times, the threaded drive sliding frame reciprocates within the groove cavity for two... Furthermore, the winding frame, in conjunction with the guide tube, drives the copper wire to wind two layers onto the stator's tooth pole, thereby achieving coordinated operation of the stator and the winding mechanism. As a result, there is no need to set up an indexing motor separately between the winding mechanism and the stator. While the worm and worm wheel rotate four times and the sliding frame completes two reciprocating strokes, they precisely drive the stator to rotate thirty degrees, so that the winding frame and guide tube can continuously wind two layers of copper wire onto the next tooth pole. This makes the winding machine structure more compact and the operation simpler, significantly improving the winding efficiency and automation level of the automotive motor stator.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] Example 1, as Figures 1 to 9 As shown in the embodiment of the present invention, an automotive motor stator winding machine includes a base 1. A sliding groove 5 is provided on the upper end of the base 1. A sliding frame 4 is slidably connected to the inner cavity of the sliding groove 5. A winding frame 10 is rotatably connected to the upper end of the sliding frame 4. A gear ring 23 is fixedly connected to the outer side of the inner cavity of the sliding frame 4. A gear disc 13 is meshed with the gear ring 23. A wire tube 11 is fixedly connected to the upper end of the winding frame 10 for guiding the discharge of copper wire. A positioning adjustment component 7 is provided on the upper end of the base 1.

[0038] The positioning adjustment component 7 includes a rotating column 71 rotatably connected to the upper end of the base 1. A fixed cylinder 73 is fixedly connected to the upper end of the rotating column 71. A cross groove 74 is opened inside the fixed cylinder 73, and a sliding column 79 is fixedly connected to the inner cavity of the cross groove 74. Two sliding discs 75 are slidably connected to the outside of the sliding column 79. A push rod 77 is rotatably connected to the inner cavity of the sliding disc 75. A clamping plate 78 is rotatably connected to one end of the push rod 77. Two first springs 76 are arranged between the sliding discs 75, and the first springs 76 abut against the inner wall of the fixed cylinder 73, which can lift the sliding discs 75 to drive the clamping plate 78 to expand, for clamping and fixing stators 8 of different models.

[0039] Specifically, in existing technologies, the stator is usually mounted on the insert post, and then an electric push rod is used to push the pressing post from the top of the stator to press and fix it. Then, the winding mechanism is controlled in conjunction with the wire clamping mechanism to clamp and fix the copper wire end, and the winding mechanism is driven to wind the stator. However, this stator fixing mechanism is not only costly, but also has limitations when clamping and fixing different models of stators. Due to the thickness of the insert post, when installing a larger stator, the remaining control of the insert post in the inner cavity of the stator can cause the stator to move, making it difficult for the winding mechanism to accurately wind the stator. Conversely, smaller stators are difficult to install outside the insert post, thus greatly affecting the stator winding operation.

[0040] In this invention, when the stator 8 is wound, the stator 8 is installed outside the fixed cylinder 73, and the clamping plate 78 is pressed to drive the push rod 77. The push rod 77 pushes the slide plate 75 to press the first spring 76 closer together, so that the clamping plate 78 slides into the inner cavity of the cross groove 74, and the stator 8 slides into the outside of the fixed cylinder 73. Then, the first spring 76 bounces up the slide plate 75, and the slide plate 75 drives the push rod 77 to push the clamping plate 78 to expand, so that the clamping plate 78 clamps and fixes the stator 8 from the inner cavity. Then, the copper wire end is clamped and fixed by the external clamping mechanism. Then, the gear plate 13 is driven to rotate, and the gear plate 13 meshes with the transmission gear ring 23 to rotate, so that the gear ring 23 drives the winding frame 10 to rotate synchronously. Then, the winding frame 10 uses the wire tube 11 to drive the copper wire to rotate, so that the copper wire winds the stator 8. Moreover, the fixed cylinder 73 can clamp and position different models of stator 8, thereby solving the above problems.

[0041] like Figures 3 to 5 As shown, a wire assembly 6 is rotatably connected to the outside of the rotating column 71, and the wire assembly 6 includes an L-shaped fixing bracket 61 rotatably connected to the outside of the rotating column 71. One end of the L-shaped fixing bracket 61 is fixedly installed to the base 1.

[0042] like Figures 3 to 5 As shown, the L-shaped fixing bracket 61 has a groove 62 on its outside. An annular sliding column 63 is fixedly connected to the inner cavity of the groove 62. A T-shaped sliding rod 64 is slidably connected to the outside of the annular sliding column 63. An L-shaped clamping rod 66 is slidably connected to one end of the T-shaped sliding rod 64. The outside of the L-shaped clamping rod 66 is set as a semi-circular arc to guide the copper wire into the inner cavity of the stator.

[0043] like Figure 1 , Figures 3 to 5 As shown, a second spring 65 is fixedly connected to the inner wall of the groove 62, and one end of the second spring 65 is fixedly connected to the T-shaped slide rod 64. The T-shaped slide rod 64 is located in the inner cavity of the L-shaped clamp rod 66 and a first tension spring 67 is fixedly connected to it, and one end of the first tension spring 67 is fixedly connected to the inner cavity of the L-shaped clamp rod 66.

[0044] Specifically, before installing the stator 8, the stator 8 is inserted into the outside of the fixed cylinder 73, and the inner cavity of the stator 8 is clamped and fixed using the clamping plate 78. When the stator 8 is installed outside the fixed cylinder 73, the stator 8 will push the L-shaped clamping rod 66 to expand outward. At the same time, the L-shaped clamping rod 66 compresses the first tension spring 67 and slides outward outside the T-shaped slide rod 64. After the stator 8 is installed and fixed, the first tension spring 67 pulls the L-shaped clamping rod 66 to return to its original position, so that the L-shaped clamping rod 66 can evenly fit the outside of the stator 8. The clamping rod 66 is designed with a semi-circular arc shape on the outside, which can better guide the copper wire into the outside of the stator 8 cavity, thereby preventing the copper wire from getting tangled in other slots of the stator 8. This solves the problem that existing automotive motor stator winding machines can only wind wires into slots for stators of the same model. This makes it difficult to protect adjacent slots of the stator when winding stators with larger or smaller slots, causing the winding mechanism to easily wind copper wire into adjacent slots, resulting in substandard stator winding quality.

[0045] like Figures 2 to 4 As shown, a worm gear 72 is installed on the outside of the inner cavity of the sliding groove 5 on the rotating column 71. A worm 22 is meshed on the outside of the worm gear 72. A connecting shaft 21 is fixed inside the worm 22 and is rotatably connected to the base 1.

[0046] like Figures 2 to 4 As shown, a servo motor 17 is installed inside the base 1, and a transmission bevel gear assembly 18 is provided at the output shaft end of the servo motor 17. The transmission bevel gear assembly 18 is connected to a driven bevel gear assembly 19 via a rotating shaft. The driven bevel gear assembly 19 is connected to a reciprocating screw 20, and one end of the reciprocating screw 20 is fixedly connected to the connecting shaft 21.

[0047] Specifically, after the stator 8 is clamped and fixed, the servo motor 17 is started to drive the transmission bevel gear assembly 18 to rotate, and the transmission bevel gear assembly 18 drives the driven bevel gear assembly 19 to rotate through the rotating shaft. At the same time, the driven bevel gear assembly 19 drives the reciprocating screw 20 to rotate, which in turn causes the reciprocating screw 20 to reciprocate in the inner cavity of the slide groove 5 by thread transmission of the sliding frame 4. This causes the sliding frame 4 to drive the winding frame 10 and the wire cylinder 11 to reciprocate towards and away from the stator 8. Then, the winding frame 10 and the wire cylinder 11 are driven to rotate, and the winding frame 10, in conjunction with the wire cylinder 11, drives the copper wire to wind the grooves of the stator 8. During the rotation of the reciprocating screw 20, the connecting shaft 21 is driven to rotate, and the connecting shaft 21 drives the worm gear 22 to rotate, which in turn drives the worm gear 72 by thread transmission. The worm gear 22 rotates four times, which in turn causes the threaded drive worm wheel 72 to rotate thirty degrees. The reciprocating screw 20 rotates four times, which causes the threaded drive sliding frame 4 to slide back and forth twice in the inner cavity of the slide groove 5. This allows the winding frame 10 to work with the wire cylinder 11 to wind copper wire around the teeth of the stator 8 in two layers, thereby achieving coordinated operation of the stator 8 and the winding mechanism, improving the automation level of the winding machine. This solves the problem that existing automotive motor stator winding machines, when winding the stator, usually drive the winding mechanism to wind the teeth of the stator. After the teeth of the stator are wound, a separate motor is needed to drive the insertion pin to rotate, and the insertion pin drives the stator to rotate to adjust the winding teeth. This results in a complex structure and operation of the winding machine and low winding efficiency of the stator.

[0048] Example 2, as Figure 1 and Figure 9 As shown, a fixed frame 2 is fixedly connected to one side of the upper surface of the base 1. A wire spool 3 is installed inside the upper end of the fixed frame 2. A control motor 16 is installed inside one end of the sliding frame 4. The output shaft end of the control motor 16 is fixedly connected to the gear plate 13.

[0049] like Figure 1 and Figure 9 As shown, a support column 12 is rotatably connected inside the winding frame 10. A first strong magnet 14 is fixed to one end of the support column 12 in the inner cavity of the sliding frame 4. A second strong magnet 15 is provided in the inner cavity of the sliding frame 4. Both the first strong magnet 14 and the second strong magnet 15 are L-shaped and can attract each other to fix the support column 12.

[0050] like Figure 1 , Figures 6 to 8As shown, a self-adjusting wire assembly 9 is fixedly connected to one end of the support column 12, and the self-adjusting wire assembly includes a push block 91 fixedly connected to one end of the support column 12. Both the upper and lower ends of the push block 91 are slidably connected to an L-shaped wire frame 92, and a rack 93 is fixedly connected to the inner wall of the L-shaped wire frame 92. The rack 93 is meshed with a T-shaped gear ring 910. A ratchet mechanism 911 is provided in the inner cavity of the T-shaped gear ring 910. Both the upper and lower walls of the inner cavity of the push block 91 are provided with a storage groove 99. A second tension spring 98 is fixedly connected to the bottom of the inner cavity of the storage groove 99. One end of the second tension spring 98 is fixedly connected to the L-shaped wire frame 92.

[0051] like Figure 1 , Figures 6 to 8 As shown, a gear 912 is rotatably connected to the inner cavity of the push block 91. The gear 912 is fixedly installed on the outside of the ratchet mechanism 911. A fixing rod 94 is fixedly connected to the inner wall of the push block 91. A third spring 95 is fixedly connected to the bottom of the inner cavity of the fixing rod 94. A telescopic rod 96 is fixedly connected to one end of the third spring 95. A stop plate 97 is fixedly connected to one end of the telescopic rod 96. A transmission rack is provided at the upper end of the telescopic rod 96, and the transmission rack meshes with the gear 912.

[0052] Specifically, after the stator 8 is clamped and fixed, the drive sliding frame 4 moves the support column 12 closer to the stator 8, and the support column 12 moves the push block 91 synchronously. This causes the push block 91 to move the abutment plate 97 to abut against the surface of the stator 8. At the same time, the abutment plate 97 presses the L-shaped clamping rod 66 away from each other, causing the L-shaped clamping rod 66 to move the T-shaped slide rod 64 to press the second spring 65 to slide outside the annular slide column 63. After the abutment plate 97 abuts against the surface of the stator 8, the abutment plate 97 will push... The telescopic rod 96 compresses the third spring 95 and slides into the inner cavity of the fixed rod 94. When the telescopic rod 96 slides into the inner cavity of the fixed rod 94, it drives the transmission rack to move synchronously. At the same time, the transmission rack meshes with the transmission gear 912 and rotates clockwise, causing the gear 912 to drive the ratchet mechanism 911 to rotate clockwise. This causes the ratchet mechanism 911 to drive the T-shaped gear ring 910 to rotate synchronously. Simultaneously, the T-shaped gear ring 910 meshes with the transmission rack 93 and moves, causing the rack 93 to drive the L-shaped guide frame. The L-shaped guide frame 92 slides out of the inner cavity of the push block 91, allowing it to slide to the outside of both ends of the stator 8. The second tension spring 98 pulls the L-shaped guide frame 92 back to its original position, causing it to move synchronously with the rack 93. Simultaneously, the rack 93 engages with the T-shaped gear ring 910, allowing it to rotate freely. This enables the L-shaped guide frame 92 to clamp both ends of the stator 8, better guiding the copper wire into the tooth grooves of the stator 8 for winding. This allows the L-shaped guide frame 92 to adaptively adjust its clamping according to different sizes and models of stator 8, effectively guiding the copper wire into the tooth groove cavity for winding. This solves the problem that existing automotive motor stator winding machines typically only clamp and guide copper wire for winding on the same model of stator, requiring operators to replace the guide frame at the front of the winding mechanism when processing larger or smaller stators, which is not only cumbersome but also affects the winding efficiency.

[0053] The working principle is as follows: Before installing the stator 8, the stator 8 is inserted into the outside of the fixed cylinder 73 and clamped and fixed by the clamping plate 78. When the stator 8 is installed outside the fixed cylinder 73, the stator 8 will push the L-shaped clamping rod 66 to expand outward. At the same time, the L-shaped clamping rod 66 squeezes the first tension spring 67 and slides outward on the outside of the T-shaped slide rod 64 to expand outward. After the stator 8 is installed and fixed, the first tension spring 67 pulls the L-shaped clamping rod 66 to reset, so that the L-shaped clamping rod 66 can evenly fit the outside of the stator 8. Moreover, the outside of the L-shaped clamping rod 66 is set as a semi-circular arc, which can better guide the copper wire into the outside of the inner cavity of the stator 8, thereby preventing the copper wire from getting tangled in other slots of the stator 8.

[0054] After the stator 8 is clamped and fixed, the servo motor 17 is started to drive the transmission bevel gear assembly 18 to rotate, and the transmission bevel gear assembly 18 drives the driven bevel gear assembly 19 to rotate through the rotating shaft. At the same time, the driven bevel gear assembly 19 drives the reciprocating screw 20 to rotate, which in turn causes the reciprocating screw 20 to reciprocate the sliding frame 4 in the inner cavity of the slide groove 5. This causes the sliding frame 4 to drive the winding frame 10 and the wire cylinder 11 to reciprocate towards and away from the stator 8. Then, the winding frame 10 and the wire cylinder 11 are driven to rotate, and the winding frame 10, in conjunction with the wire cylinder 11, drives the copper wire to enter the tooth groove of the stator 8. During the winding process, the reciprocating screw 20 rotates, which in turn drives the connecting shaft 21 to rotate. Simultaneously, the connecting shaft 21 drives the worm 22 to rotate, causing the worm 22 to drive the worm wheel 72 to rotate. When the worm 22 rotates four times, the worm wheel 72 rotates thirty degrees. When the reciprocating screw 20 rotates four times, the sliding frame 4 slides back and forth twice in the inner cavity of the groove 5. This allows the winding frame 10 to work with the wire cylinder 11 to wind the copper wire around the teeth of the stator 8 in two layers, thereby achieving coordinated operation of the stator 8 and the winding mechanism and improving the automation level of the winding machine.

[0055] When the drive sliding frame 4 moves the support column 12 closer to the stator 8, the support column 12 moves the push block 91 synchronously. This causes the push block 91 to move the abutment plate 97 to abut against the surface of the stator 8. Simultaneously, the abutment plate 97 presses the L-shaped clamping rod 66 away from each other, causing the L-shaped clamping rod 66 to move the T-shaped sliding rod 64 to press the second spring 65 to slide outside the annular sliding column 63. After the abutment plate 97 abuts against the surface of the stator 8, the abutment plate 97 pushes the telescopic rod 96 to press the third spring 95 into the inner cavity of the fixed rod 94. When the telescopic rod 96 slides into the inner cavity of the fixed rod 94, it drives the transmission rack to move synchronously. At the same time, the transmission rack meshes with the transmission gear 912 and rotates clockwise, causing the gear 912 to drive the ratchet mechanism 911 to rotate clockwise. This, in turn, causes the ratchet mechanism 911 to drive... The T-shaped gear ring 910 rotates synchronously, and at the same time, the T-shaped gear ring 910 meshes with the drive rack 93 to move, causing the rack 93 to drive the L-shaped wire guide frame 92 to slide away from each other and out of the inner cavity of the push block 91. This allows the L-shaped wire guide frame 92 to slide to the outside of both ends of the stator 8. By using the second tension spring 98 to pull the L-shaped wire guide frame 92 back to its original position, the L-shaped wire guide frame 92 drives the rack 93 to move synchronously. At the same time, the rack 93 meshes with the drive T-shaped gear ring 910 to rotate freely, thereby allowing the L-shaped wire guide frame 92 to clamp both ends of the stator 8. This allows the L-shaped wire guide frame 92 to better guide the copper wire into the tooth groove of the stator 8 for winding processing. This enables the L-shaped wire guide frame 92 to adaptively adjust the clamping according to different sizes and models of the stator 8, so that it can effectively guide the copper wire to slide into the inner cavity of the tooth groove for winding processing.
