Description

Technical Field

[0001] This utility model relates to the technical field of brushless motor winding tools, and in particular to a winding device for brushless motors. Background Technology

[0002] Brushless motors are widely used in new energy vehicles, home appliances and other fields due to their high efficiency and low noise. The uniformity and tightness of the stator winding directly affect the motor performance. Traditional winding devices rely heavily on manual assistance and have a low degree of automation, which makes it difficult to meet the requirements of large-scale production for winding accuracy and efficiency. There is an urgent need to optimize the structure to improve automation and accuracy.

[0003] Existing winding devices for brushless motors have significant drawbacks. Traditional devices typically consist of a fixed winding shaft, manually adjustable guide wheels, and simple clamps. The stator clamping is unstable, leading to easy deviation during winding and uneven coil distribution. Guide wheel position adjustment relies on manual operation, making it impossible to precisely adapt to stator slots of different specifications, resulting in inconsistent winding tension. After winding, manual cutting of the copper wire is required, which is cumbersome and easily damages the coil. The lack of a linkage control mechanism means that winding, guiding, and cutting actions are not synchronized, resulting in low production efficiency. Ultimately, this leads to uneven winding and low efficiency. Therefore, this application designs a winding device for brushless motors to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a winding device for a brushless motor, comprising a worktable, a turntable rotatably mounted on the upper end of the worktable, and a guide groove formed on one side of the upper end of the worktable. A guide block is slidably disposed inside the guide groove, an electric push rod is installed inside the guide block, an installation component is provided at the upper end of the electric push rod, a column is installed at the upper end of the turntable, a clamping component is provided inside the column, a cutting component is provided on one side of the upper end of the column, and a stator is installed at the upper end of the turntable through the clamping component.

[0006] Preferably, a first motor is installed on the side of the workbench, a first lead screw is rotatably installed on one side of the guide groove, the first lead screw is coaxially fixed to the output shaft of the first motor, and one side of the guide block is threadedly connected to the first lead screw.

[0007] Preferably, the mounting assembly consists of a rotating shaft and a connecting rod. The upper end of the output rod of the electric actuator is equipped with a mounting plate. The rotating shaft is rotatably mounted on the upper end of the mounting plate. The connecting rod is fixedly mounted on the side end of the mounting plate. The other end of the connecting rod is fixedly equipped with a mounting ring.

[0008] Preferably, the clamping assembly consists of a knob and a sliding plate. The column has a sliding groove inside, and the sliding plate is slidably installed inside the sliding groove. A second lead screw is rotatably installed inside the sliding groove. The knob is rotatably installed at the upper end of the column and is coaxially fixed to the second lead screw. A sliding rod is slidably installed at the side end of the sliding groove, and a clamping block is hinged to the side end of the sliding rod.

[0009] Preferably, a tangent plate is installed on one side of the upper end of the column, a tangent groove is opened on one side of the upper end of the tangent plate, a third motor is installed on the side end of the tangent plate, a second motor is installed on the lower end of the turntable, and the turntable and the output shaft of the second motor are coaxially fixedly connected.

[0010] Preferably, the cutting assembly consists of two cutting blades and a bidirectional lead screw. The two cutting blades are slidably mounted in opposite directions inside the cutting groove, and the bidirectional lead screw is rotatably mounted inside the cutting groove and coaxially fixed to the output shaft of the third motor. The two cutting blades are threadedly connected to both ends of the bidirectional lead screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a first motor in conjunction with a first lead screw, a guide block, and an electric push rod. The first motor drives the guide block to move along the guide groove, and the electric push rod adjusts the height of the mounting components, achieving precise guidance of the copper wire. This facilitates adaptation to different stator slots, improves winding accuracy, and thus achieves a precise guiding function. A second motor in conjunction with a turntable and a column drives the turntable to rotate the stator, completing the winding process in conjunction with the guiding components. This eliminates the need for manual intervention, improving winding efficiency and achieving an automated winding function. A third motor in conjunction with a bidirectional lead screw and a cutting blade drives the cutting blade to move in opposite directions, automatically cutting the copper wire. This avoids damage to the coil from manual operation, improves cutting convenience, and thus achieves an automatic cutting function. A knob in conjunction with a second lead screw, a sliding plate, and a clamping block allows the clamping block to be adjusted to clamp the stator, adapting to stators of different sizes and ensuring stability during winding, thus achieving an adaptive clamping function. Ultimately, this solves the problems of uneven winding and low efficiency in existing devices. Attached Figure Description

A mounting ring is fixedly mounted on the other end of the connecting rod 11. The copper wire passes through the mounting ring.

[0021] Working Principle: When using this invention, first connect the power supply, place the stator 3 on the upper end of the column 2, rotate the knob 9 to drive the second lead screw to move the sliding plate 10, and clamp the stator 3 through the sliding rod linkage clamping block; the operator fixes one end of the copper wire to the terminal block of the stator 3, and the copper wire passes through the mounting ring and the winding post in sequence; set the winding parameters through the control panel, start the first motor 5, drive the first lead screw to move the guide block along the guide groove to the initial winding position, start the electric push rod 4 to adjust the height of the mounting plate so that the copper wire is aligned with the target slot of the stator 3; start the second motor 8, drive the turntable 7 to rotate the stator 3, and at the same time, the first motor 5 and the electric push rod 4 work together to move the mounting components so that the copper wire is evenly wound in the slot of the stator 3. Within the winding position, the rotating shaft 6 rotates synchronously with the winding of the copper wire to prevent the copper wire from getting tangled. When the preset counter records that the number of winding turns has reached the preset value, it is determined that a winding is completed. The electric push rod 4 and the first motor 5 drive the connecting rod 11 to move to the upper end of the cutting plate 12. At this time, the copper wire is in the cutting groove. The third motor 13 is started, driving the bidirectional lead screw to move the two cutting blades 14 in opposite directions to cut the copper wire in the cutting groove. After cutting, the third motor 13 reverses to reset the cutting blades 14. The electric push rod 4 and the first motor 5 are adjusted to the position corresponding to the next set of slots, and the above winding action is repeated. After all slots are wound, all motors are turned off. Then, the knob 9 is turned in the opposite direction to release the clamping block, and the winding completed stator 3 is removed. Finally, the power is turned off to complete the entire winding process.
