Abstract
Description
Technical Field
[0001] This invention relates to a winding machine, specifically to a winding machine for a disc motor and a method for winding multiple wires. Background Technology
[0002] Disc motors generally refer to axial permanent magnet motors, which have advantages such as compact structure, high efficiency, and high power density. They are particularly suitable for applications requiring high torque density and limited space, such as electric vehicles, renewable energy systems, in-vehicle energy storage systems, and industrial equipment. Currently, there is little or no use of disc motor winding technology in the market; most of the winding work is done manually by workers on disc motors.
[0003] The manual winding of wires onto a disc motor by workers is extremely inefficient, has high labor costs, and results in inconsistent winding tension and uneven wire arrangement, leading to very poor winding quality. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a winding machine for disc motors and a multi-wire winding method. By using four-axis linkage and multiple wires to wind at the same time, the production efficiency of the product is greatly improved; labor costs are greatly reduced; the winding tightness is consistent, the wires are evenly arranged and the wires do not cross and tangle with each other, thus obtaining excellent winding effect.
[0005] The present invention relates to a winding machine for a disc motor, which is achieved through the following technical solution: including a needle tip flipping mechanism, a wire clamping mechanism, a fixture table, and a wire cutting mechanism;
[0006] The needle tip flipping mechanism is located above the fixture table, while the wire clamping mechanism and the wire cutting mechanism are located next to the fixture table.
[0007] As a preferred technical solution, the needle tip flipping mechanism includes a bracket, a needle tip, a needle tip block, and a needle tip holder. The bracket is set above the fixture table, and a first cylinder is installed below the bracket. The needle tip holder is installed on the output shaft of the first cylinder. The needle tip block is installed on the needle tip holder, and a needle tip is installed on the needle tip block.
[0008] As a preferred technical solution, the wire clamping mechanism includes a wire clamp base, a wire pressing block, a wire clamp, a push block, and a second cylinder. The wire clamp is fixedly connected to the wire pressing block and the push block in sequence. The wire clamp, the wire pressing block, and the push block are all connected to the wire clamp base and are positioned above the wire clamp base. The wire clamp base is fixedly connected to the second cylinder, and the push block is fixedly connected to the floating joint of the second cylinder.
[0009] As a preferred technical solution, the jig table includes a winding jig, positioning claws, a product table, positioning pins, a starting wire winding post, and a third cylinder. The winding jig is a hollow cylinder. The product table is located in the upper middle part of the winding jig and is connected to the winding jig. The product is placed on the product table. Multiple third cylinders are arranged around the outer perimeter of the winding jig. Multiple positioning claws are arranged around the winding jig, and the multiple positioning claws are evenly distributed around the outer perimeter of the winding jig at 360°. The positioning claws are fixedly connected to the winding jig, and each positioning claw is connected to a corresponding cylinder. A starting wire winding post is arranged on the side of the winding jig, and positioning pins are also arranged around the winding jig.
[0010] As a preferred technical solution, the wire cutting mechanism includes a pneumatic shear, scissors, a mounting plate, and a fourth cylinder. The scissors are connected to the pneumatic shear, the mounting plate is disposed between the pneumatic shear and the fourth cylinder, and the pneumatic shear is fixedly connected to the mounting plate. The mounting plate is also connected to the fourth cylinder.
[0011] A method for multi-wire winding of a winding machine for a disc motor specifically includes the following steps:
[0012] S1. Place the disc motor in the disc, and simultaneously exit three or more wires through three or more holes of the multi-hole wire nozzle of the needle tip flipping mechanism.
[0013] S2. The needle tip flipping mechanism moves radially to wind three or more wires around the wire clamp seat of the wire clamping mechanism. The cylinder of the wire clamping mechanism is activated, pushing the push block and wire clamp to move, so that the wires are fixed between the wire clamp seat and the wire pressing block.
[0014] S3. The positioning claw of the fixture table is activated by a cylinder, and the positioning claw simultaneously fixes the winding fixture and the product table.
[0015] S4. The winding fixture rotates until the starting wire winding post on the winding fixture rotates to the 1 o'clock position; at the same time, the needle tip flipping mechanism returns to the top of the starting wire winding post, then moves downward, and then the action winds the wire onto the starting wire winding post.
[0016] S5. The wire clamping mechanism's pressure block, wire clamp, and push block retract, and the wire clamping mechanism returns to the released state; at the same time, the winding fixture continues to rotate, and the needle tip flipping mechanism returns to the 12 o'clock position of the disc motor, winding the wire onto the positioning pin.
[0017] S6. The needle tip flipping mechanism drives the multi-hole wire tip to pass through the gap between the teeth of the disc motor and move from the 12 o'clock position to the exact center of the disc motor.
[0018] S7. The winding fixture drives the disc motor to rotate one revolution, and the needle tip flipping mechanism continues to move from the middle to the 6 o'clock position of the disc motor along the Y-axis.
[0019] S8. The needle tip flipping mechanism and the winding fixture rotate simultaneously and in the same direction to the 12 o'clock position.
[0020] S9. The needle tip flipping mechanism moves from the 12 o'clock position back to the middle position of the disc motor. At the same time, the winding fixture continues to rotate one revolution to wind the wire.
[0021] S10, the needle tip flipping mechanism and the winding fixture continue to rotate synchronously and in the same direction to the 12 o'clock position, during which the wire tip block and the multi-hole wire tip rotate as a whole to wind the wire;
[0022] S11. Repeat the above actions S6~S10 to wind the first tooth of the disc motor.
[0023] S12, the winding fixture and the needle tip flipping mechanism rotate together and stop at the 9 o'clock position of the winding fixture. The needle tip flipping mechanism passes the wire through the next ring positioning pin of the winding fixture.
[0024] S13, the winding fixture and the needle tip flipping mechanism rotate back to the 12 o'clock position together, and the needle tip flipping mechanism moves to wind the wire onto the positioning pin;
[0025] S14. Repeat the above actions S6~S10 to wind the next tooth of the disc motor.
[0026] S15. Once all the wires are wound, the wire cutting mechanism moves back and forth as controlled by the cylinder. The air shears and scissors move forward, and the scissors cut the wire hanging on the positioning pin of the winding fixture. The needle tip flipping mechanism and the winding fixture continue to rotate at a certain angle and then stop. The scissors cut off a set of wires hanging on the positioning pin.
[0027] S16. When all the wires on the positioning pins have been cut, the needle tip flipping mechanism pulls the wires through the wire clamping mechanism. The wire clamping mechanism starts, clamps the wires, and at the same time cuts the wires at the end connected to the disc motor. The needle tip flipping mechanism returns to the 12 o'clock position, the positioning claws of the fixture table are released, and the disc motor with the wires wound is manually removed.
[0028] The beneficial effects of this invention are:
[0029] This invention differs from the traditional manual winding method, greatly improving production efficiency and reducing labor costs;
[0030] The needle tip flipping mechanism of the present invention has a three-hole wire tip that can wind three wires at the same time, which is faster than ordinary single wire winding.
[0031] In addition, the needle tip flipping mechanism can also flexibly link the four axes of X, Y, Z and θ, closely cooperating with the rotation of the jig table. Furthermore, through the synchronous rotation of the winding jig and the needle tip flipping mechanism, the winding and laying of wires are uniform and the wires do not cross or tangle with each other.

[0045] The present invention discloses a multi-wire winding method for a disc motor winding machine, taking the winding of three wires and a three-hole wire nozzle as an example, and the specific steps are as follows:
[0046] S1. Place the disc motor in, and the three wires will exit simultaneously through the three holes of the three-hole wire nozzle of the needle tip flipping mechanism.
[0047] S2. The needle tip flipping mechanism moves radially, and the three wires are wound around the wire clamp seat of the wire clamping mechanism. The cylinder of the wire clamping mechanism is activated, pushing the push block and wire clamp to move, so that the three wires are fixed between the wire clamp seat and the wire pressing block.
[0048] S3. The positioning claw of the fixture table is activated by a cylinder, and the positioning claw simultaneously fixes the winding fixture and the product table.
[0049] S4. The winding fixture rotates until the starting wire winding post on the winding fixture rotates to the 1 o'clock position; at the same time, the needle tip flipping mechanism returns to the top of the starting wire winding post, then moves downward, and then the action winds the wire onto the starting wire winding post.
[0050] S5. The wire clamping mechanism's pressure block, wire clamp, and push block retract, and the wire clamping mechanism returns to the released state; at the same time, the winding fixture continues to rotate, and the needle tip flipping mechanism returns to the 12 o'clock position of the disc motor, winding the wire onto the positioning pin.
[0051] S6. The needle tip flipping mechanism drives the three-hole wire tip to pass through the gap between the teeth of the disc motor and move from the 12 o'clock position to the exact center of the disc motor.
[0052] S7. The winding fixture drives the disc motor to rotate one revolution, and the needle tip flipping mechanism continues to move from the middle to the 6 o'clock position of the disc motor along the Y-axis.
[0053] S8. The needle tip flipping mechanism and the winding fixture rotate simultaneously and in the same direction to the 12 o'clock position.
[0054] S9. The needle tip flipping mechanism moves from the 12 o'clock position back to the middle position of the disc motor. At the same time, the winding fixture continues to rotate one revolution to wind the wire.
[0055] S10, the needle tip flipping mechanism and the winding fixture continue to rotate synchronously and in the same direction to the 12 o'clock position, during which the wire tip block and the three-hole wire tip rotate as a whole to wind the wire;
[0056] S11. Repeat the above steps 6 to 10 to wind the first tooth of the disc motor.
[0057] S12, the winding fixture and the needle tip flipping mechanism rotate together and stop at the 9 o'clock position of the winding fixture. The needle tip flipping mechanism passes the wire through the next ring positioning pin of the winding fixture.
[0058] S13, the winding fixture and the needle tip flipping mechanism rotate back to the 12 o'clock position together, and the needle tip flipping mechanism moves to wind the wire onto the positioning pin;
[0059] S14. Repeat steps 6 to 10 above to wind the next tooth of the disc motor.
[0060] S15. Once all the wires are wound, the wire cutting mechanism moves back and forth as controlled by the cylinder. The air shears and scissors move forward, and the scissors cut the wire hanging on the positioning pin of the winding fixture. The needle tip flipping mechanism and the winding fixture continue to rotate at a certain angle and then stop. The scissors cut off a set of wires hanging on the positioning pin.
[0061] S16. When all the wires on the positioning pins have been cut, the needle tip flipping mechanism pulls the wires through the wire clamping mechanism. The wire clamping mechanism starts, clamps the wires, and at the same time cuts the wires at the end connected to the disc motor. The needle tip flipping mechanism returns to the 12 o'clock position, the positioning claws of the fixture table are released, and the disc motor with the wires wound is manually removed.
[0062] In a multi-wire winding method for a disc motor winding machine, the 1 o'clock direction, 12 o'clock direction, etc., are described in terms of time position.
[0063] This invention can simultaneously control the winding action of a disc motor through four-axis linkage of X, Y, Z and θ axes; secondly, unlike ordinary single-wire winding, this invention can achieve the purpose of multi-wire winding (three or more wires); most importantly, it can achieve the excellent effect of the wound wires not crossing and tangling with each other.

Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
