Description

Technical Field

[0001] This invention relates to the field of automotive motor stator technology, specifically to an automotive starter motor stator coil winding processing system. Background Technology

[0002] An automotive starter motor, also known as an automotive starter motor, is a machine used to start the engine when a car is cold. It converts the electrical energy of the battery into mechanical energy, thereby driving the flywheel of the car engine to rotate and start the engine. The automotive starter motor mainly consists of three parts: a DC motor, a transmission engagement mechanism, and an electromagnetic switch. During the manufacturing process of the DC motor, the coil needs to be wound around the motor stator. The winding of the stator coil is usually done automatically using winding equipment.

[0003] Existing stator coil winding equipment for automotive starter motors typically consists of a winding assembly, a clamping assembly, and a drive assembly. The clamping assembly holds the stator, while the winding assembly rotates relative to the winding slots on the stator from the outside, causing the copper wire to be evenly wound around the stator.

[0004] However, since the winding slots of the stator are not necessarily located on the outer wall of the stator, and for different types of stators, some winding slots are located on the inner wall of the stator, the winding assembly of existing winding equipment has limited rotation inside the stator, making it difficult to use for stators with inner winding. In addition, before winding copper wire on the stator, insulating paper needs to be inserted into the winding slots to avoid short circuits. However, since current winding equipment does not have the dual function of winding and inserting paper, the insertion of insulating paper in the current stator requires manual operation or separate processing equipment, resulting in the stator coil winding being carried out in steps, which is time-consuming. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This automotive starter motor stator coil winding system, by setting up a winding block, a lead-out assembly, and a lifting cylinder, uses the winding block to replace the winding slot on the stator. The copper wire is wound onto the winding block, making the copper wire evenly wound on the winding block. After the lifting cylinder drives the winding block to descend, the drive cylinder pushes the movable block to move. The movable block drives the pusher block to push the copper wire on the winding block into the winding slot of the stator. By using the winding block and lead-out assembly as a transfer mechanism, the winding equipment can be used for stators with internal slots, and the copper wire winding process is not limited by space.

[0019] 2. This automotive starter motor stator coil winding processing system utilizes an insulating paper adsorption seat. A rotary motor drives a central shaft to rotate, which in turn drives a central column. The central column, via a U-shaped frame, drives the insulating paper adsorption seat to rotate. A negative pressure pump draws suction from the vent pipe, which in turn draws suction from the inner cavity of the insulating paper adsorption seat. This creates suction force in the adsorption holes, transferring the insulating paper to the designated insertion position. A lifting cylinder drives a winding block to move downwards, which, via a guide sleeve, drives the U-shaped frame to move downwards. The U-shaped frame then carries the insulating paper adsorption seat, inserting it into the stator's winding slot. After the negative pressure pump's suction effect disappears, the lifting cylinder drives the insulating paper adsorption seat to move upwards, ensuring the insulating paper is in the stator's winding slot. This achieves automatic insertion of insulating paper into the stator. The U-shaped frame is used both for the arrangement of copper wire during winding and for driving the insulating paper adsorption seat to pick up the insulating paper.

[0020] 3. This automotive starter motor stator coil winding processing system, through the setting of the arrangement component, when the copper wire is wound on the winding block, the drive motor drives the first bevel gear to rotate the second bevel gear, the second bevel gear drives the rotating shaft to rotate, the rotating shaft drives the two drive gears to rotate, the two drive gears drive the two racks to move, and the racks drive the U-shaped frame to move to one side, so that the U-shaped frame drives the guide block to move, guiding and arranging the wound copper wire, so that the copper wire is evenly wound on the winding block.

[0021] 4. This automotive starter motor stator coil winding processing system, by setting up a clamping drive assembly, uses a clamping cylinder to retract and pull the side ear downwards, the side ear to drive the pressure plate downwards, the pressure plate to drive the insert block to move downwards in the slide groove, the inclined edge of the insert block to squeeze the clamping block, pushing the clamping block to extend out of the slide groove, and multiple clamping blocks extending simultaneously to clamp the outer wall of the stator inserted into the mounting base, achieving the effect of rapid clamping of the stator.

[0033] like Figures 1 to 7As shown, this embodiment of the automotive starter motor stator coil winding processing system includes a worktable 1, which is circular. A base plate 2 is mounted on the upper surface of the worktable 1. The base plate 2 is annular. The stator 4 is inserted into the mounting base 3 and rests on the base plate 2. A height difference is formed between the inner wall of the base plate 2 and the worktable 1, providing space for the copper wire wound on the winding block 7 to enter the winding slot of the stator 4. A mounting base 3 is mounted on the upper surface of the base plate 2. The mounting base 3 is annular. The stator 4 is movably placed in the center of the mounting base 3. Several winding slots are opened on the inner wall of the stator 4. This equipment is suitable for winding this type of stator 4. A central column 5 is provided through the center of the mounting base 3. The central column 5 passes through the mounting base 3 and the base plate 2 and then connects with the worktable via the central shaft 51. The platform 1 is connected, and a lifting cylinder 6 is embedded in one side of the central column 5. The lifting cylinder 6 is a rodless cylinder used to drive the winding block 7 to rise and fall. The winding block 7 is installed on the moving part of the lifting cylinder 6. The winding block 7 is rectangular. Because the stator 4 needs to be wound at intervals, the width of the winding block 7 corresponds to the sum of the distances between the winding slots of multiple stator 4. The outer side of the winding block 7 is equipped with a layout component 8 for the winding and layout of copper wire. The two sides of the central column 5 are equipped with wire exit components 9 near the bottom edge to push the copper wire wound on the winding block 7 into the winding slot of the stator 4. The mounting base 3 is equipped with a clamping drive component 10 to drive the clamping block 32 to move so that the clamping block 32 can firmly clamp the stator 4 to be processed.

[0034] A rectangular slot 71 is provided through the winding block 7. The winding block 7 is fitted onto the outside of the central post 5 through the rectangular slot 71. The winding block 7 slides up and down relative to the central post 5 through the rectangular slot 71. A drive motor 72 is embedded in the side wall of the winding block 7 on one side of the rectangular slot 71. The drive motor 72 is essentially a motor with forward and reverse rotation circuits. The shaft end of the drive motor 72 is connected to the first bevel gear 73, which serves as the driving force for the horizontal movement of the frame 81 for winding and arrangement. The top shaft end of the drive motor 72 is connected to the first bevel gear 73. A second bevel gear 74 is vertically meshed on one side of the first bevel gear 73. A rotating shaft 75 is provided through the middle of the second bevel gear 74. The winding block 7 has a bearing seat 76 connected to its side wall. The rotating shaft 75 passes through the bearing seat 76 and is connected to the bearing seat 76 by a second bearing 77. The rotating shaft 75 is rotatably connected to the winding block 7 via the second bearing 77. Both ends of the rotating shaft 75 are fitted with drive gears 78. Both sides of the drive gears 78 are connected with limiting edges 79. The outer diameter of the limiting edges 79 is larger than the outer diameter of the drive gears 78. When the drive gears 78 are meshed with the rack 88, the limiting edges 79 limit the drive gears 78. The front and rear sides of the winding block 7 are connected with guide sleeves 710 for guiding the horizontal movement of the U-shaped frame 81, so that the U-shaped frame 81 can move relative to the winding block 7.

[0035] Specifically, the bottom of the central column 5 is connected to the central shaft 51, and the central shaft 51 is connected to the worktable 1 by a first bearing 52. The bottom of the central shaft 51 passes through the worktable 1 and is connected to a rotary motor 53. The rotary motor 53 is installed at the bottom of the worktable 1, and the shaft end of the rotary motor 53 is connected to the central shaft 51. The rotary motor 53 is essentially a motor with forward and reverse circuits, which can drive the central column 5 to rotate back and forth. The central column 5 is rotatably connected to the worktable 1 via a rotating shaft 75. The central column 5 is rectangular. The width of the inner wall of the rectangular groove 71 is adapted to the width of the central column 5. The central column 5 is movably connected to the winding block 7 via the rectangular groove 71. When the lifting cylinder 6 drives the winding block 7 to rise and fall, the winding block 7 slides and rises and falls relative to the central column 5.

[0036] Furthermore, the arrangement assembly 8 includes a U-shaped frame 81 installed on the outside of the winding block 7. Guide blocks 82 are connected to both open ends of the U-shaped frame 81. The U-shaped frame 81 and guide blocks 82 are integrally connected for winding and arranging the winding block 7 on both the front and rear sides. An insulating paper adsorption seat 83 is connected to the middle of the side of the U-shaped frame 81 away from the guide blocks 82 for holding the insulating paper. Several equally spaced adsorption holes 84 are opened on the outer wall of the insulating paper adsorption seat 83. A pipe connector 85 is installed on the upper surface of the insulating paper adsorption seat 83 to connect the inner cavity of the insulating paper adsorption seat 83 to a vent pipe 86. A vent pipe 86 is connected to the top of the pipe connector 85. The vent pipe 86 has a reserved length to facilitate the central column 5 driving the insulating paper adsorption seat. 83 rotates one revolution. The other end of the vent pipe 86 is connected to a negative pressure pump 87. Two racks 88 are installed on the upper surface of the U-shaped frame 81. The two drive gears 78 are positioned corresponding to the two racks 88 on the upper surface of the U-shaped frame 81, and the drive gears 78 are meshed with the racks 88. The drive motor 72 is rotatably connected to the rotating shaft 75 via the first bevel gear 73 and the second bevel gear 74. The drive motor 72 drives the second bevel gear 74 to rotate via the first bevel gear 73. The second bevel gear 74 drives the rotating shaft 75 to rotate. The rotating shaft 75 drives the two drive gears 78 to rotate. The two drive gears 78 drive the two racks 88 to move respectively. The racks 88 drive the U-shaped frame 81 to move to one side.

[0037] Furthermore, the U-shaped frame 81 has a U-shaped cross-section. The front and rear side walls of the U-shaped frame 81 pass through the guide sleeve 710 and form a sliding connection with the winding block 7. The guide block 82 is inclined and contacts the side wall of the winding block 7. When the U-shaped frame 81 moves to one side, the U-shaped frame 81 drives the guide block 82 to move. The guide block 82 guides and arranges the wound copper wire so that the copper wire is evenly wound on the winding block 7.

[0038] Furthermore, the inner cavity of the insulating paper adsorption seat 83 is hollow, and the inner cavity of the insulating paper adsorption seat 83 is connected to the vent pipe 86 via the pipe connector 85. The inner cavity of the insulating paper adsorption seat 83 is connected to the external environment via the adsorption hole 84. The negative pressure pump 87 draws suction from the vent pipe 86, and the vent pipe 86 draws suction from the inner cavity of the insulating paper adsorption seat 83, so that the adsorption hole 84 generates an adsorption force to adsorb the insulating paper onto the outside of the insulating paper adsorption seat 83. The insulating paper adsorption seat 83 is movably inserted into the winding slot of the stator 4. After the lifting cylinder 6 drives the winding block 7 to move down, the winding block 7 drives the U-shaped frame 81 to move down via the guide sleeve 710. The U-shaped frame 81 drives the insulating paper adsorption seat 83 to carry the insulating paper and insert it into the winding slot of the stator 4.

[0039] Furthermore, the output assembly 9 includes a side plate 91 installed on the side wall of the central column 5. A drive cylinder 92 is installed on the upper surface of the side plate 91. A movable block 93 is connected to the telescopic end of the drive cylinder 92. A pusher block 94 is connected to the movable block 93. The movable block 93 and the pusher block 94 are integrally connected. The pusher block 94 is inclined. The distance between the pusher blocks 94 in the two output assemblies 9 matches the width of the winding block 7. After the winding block 7 falls to the lowest position, the pusher block 94 contacts the front and rear side walls of the winding block 7. The drive cylinder 92 pushes the movable block 93 to move. The movable block 93 drives the pusher block 94 to push the copper wire on the winding block 7 into the winding slot of the stator 4. The position of the rotation of the winding block 7 driven by the rotary motor 53 is preset to ensure that the copper wire on the winding block 7 is in the winding slot of the stator 4 after it is pushed out.

[0040] Furthermore, the inner wall of the mounting base 3 is provided with four circumferentially arranged sliding grooves 31. The sliding grooves 31 are provided with clamping blocks 32, and there are also four clamping blocks 32. A first spring 33 is connected between the clamping blocks 32 and the inner wall of the sliding grooves 31. After the squeezing force of the insert 105 on the clamping blocks 32 disappears, the first spring 33 rebounds and pulls the clamping blocks 32 back into the sliding grooves 31. The upper surface of the mounting base 3 above the four sliding grooves 31 is connected with a guide rod 34 for guiding the lifting and lowering of the pressure plate 101. A second spring 35 is sleeved on the outside of the guide rod 34.

[0041] Furthermore, the clamping drive assembly 10 includes a pressure plate 101 mounted on the mounting base 3. The pressure plate 101 is annular and is used to simultaneously drive the lifting and lowering of four insert blocks 105. The outer wall of the pressure plate 101 is connected to four side ears 102 arranged in a circumferential direction. The bottom of each of the four side ears 102 is connected to a clamping cylinder 103. The telescopic end of the clamping cylinder 103 is connected to the side ear 102. The four clamping cylinders 103 are connected to the same air source to achieve simultaneous telescopic drive. The pressure plate 101 has four through holes 104. The bottom of the pressure plate 101 on one side of the through hole 104 is connected to the insert block 105.

[0042] Furthermore, the bottom of the guide rod 34 is connected to the mounting base 3, and the top of the guide rod 34 passes through the pressure plate 101 through the through hole 104. The second spring 35 is located on the outside of the guide rod 34 between the pressure plate 101 and the mounting base 3. The clamping cylinder 103 is installed on the outer wall of the mounting base 3. By retracting the clamping cylinder 103, the side ear 102 is pulled down. The side ear 102 drives the pressure plate 101 to move down relative to the guide rod 34. The pressure plate 101 drives the insert block 105 to move down in the slide groove 31.

[0043] Furthermore, the longitudinal section of the insert 105 is a right trapezoid with a wider top and a narrower bottom. The insert 105 is inserted into the inner wall of the slide groove 31 and the inclined side of the insert 105 contacts the clamping block 32. The clamping block 32 is slidably connected to the slide groove 31 and contacts the outer wall of the stator 4. When the insert 105 moves down in the slide groove 31, the inclined side of the insert 105 squeezes the clamping block 32 and pushes the clamping block 32 out of the slide groove 31. Multiple clamping blocks 32 extend at the same time to clamp the outer wall of the stator 4 inserted into the mounting base 3, thereby achieving the effect of quickly clamping the stator 4.

[0044] The usage method of this embodiment is as follows: When the user is actually using the winding processing system to perform coil winding processing on the stator 4 of an automotive starter motor, firstly, the stator 4 to be processed is inserted into the mounting base 3. Then, the clamping cylinder 103 is activated. The clamping cylinder 103 retracts, pulling the side ear 102 downward. The side ear 102 drives the pressure plate 101 downward. The pressure plate 101 compresses the second spring 35. The pressure plate 101 drives the insertion block 105 to move downward in the slide groove 31. The inclined side of the insertion block 105 presses against the clamping block 32. The first spring 33 extends, pushing the clamping block 32 out of the slide groove 31. Multiple clamping blocks 32 extend simultaneously to press against the outer wall of the stator 4 inserted into the mounting base 3. The paper is clamped, and then the negative pressure pump 87 is started. The negative pressure pump 87 draws suction from the vent pipe 86, which in turn draws suction from the inner cavity of the insulating paper adsorption seat 83, causing the adsorption holes 84 to generate adsorption force. Then, the worker places the insulating paper on the insulating paper adsorption seat 83. The multiple adsorption holes 84 on the insulating paper adsorption seat 83 adsorb the insulating paper, forming a U-shape. Then, the lifting cylinder 6 drives the winding block 7 to move down. The winding block 7 drives the U-shaped frame 81 to move down via the guide sleeve 710. The U-shaped frame 81 drives the insulating paper adsorption seat 83 to carry the insulating paper and insert it into the winding slot of the stator 4. After the suction effect of the negative pressure pump 87 disappears, the lifting cylinder 6 drives the insulating paper adsorption seat 83 to move up. The insulating paper is left in the winding slot of the stator 4. Then, the rotary motor 53 drives the central shaft 51 to rotate, the central shaft 51 drives the central column 5 to rotate, and the central column 5 drives the winding block 7 to rotate. The winding block 7 drives the insulating paper adsorption seat 83 to rotate via the U-shaped frame 81, and inserts the insulating paper into the winding slot of the inner wall of the stator 4 in sequence. After the insulating paper is inserted, the winding block 7 returns to its highest position. The conventional winding assembly rotates to wind the internally pulled copper wire around the outer surface of the winding block 7. At the same time, the drive motor 72 drives the second bevel gear 74 to rotate via the first bevel gear 73. The second bevel gear 74 drives the rotating shaft 75 to rotate, and the rotating shaft 75 drives the two drive gears 78 to rotate. Two drive gears 78 drive two racks 88 to move, which in turn drive the U-shaped frame 81 to move to one side. This causes the U-shaped frame 81 to move the guide block 82, guiding and arranging the wound copper wire so that it is evenly wound on the winding block 7. After winding, the lifting cylinder 6 drives the winding block 7 to descend, and the drive cylinder 92 extends to push the movable block 93 to move. The movable block 93 drives the pusher block 94 to push the copper wire on the winding block 7 into the winding slot of the stator 4. The rotary motor 53 drives the rotating shaft 75 to rotate, which in turn drives the central column 5 to rotate. The central column 5 drives the winding block 7 to rotate, winding the wire sequentially into several winding slots on the inner wall of the stator 4.
