Description

Technical Field

[0001] The utility model relates to the field of winding machines, in particular to a full-automatic winding machine for heating and curing a stator coil of a linear motor. Background Art

[0002] The air-core coil of the linear motor stator is wound with enameled wire. After the winding machine on the market winds the air-core coil, it is generally heated by electric hot air to solidify the air-core coil. The electric hot air can only heat the enameled wire on the surface of the coil. The insulation layer of the adjacent wires on the surface of the coil is bonded together by hot melting. The adjacent enameled wires of the coil are bonded together so that the coil can be solidified, but the wire inside the coil is not heated and continues to be loose. If the coil is continuously overheated, the insulation layer of the wire on the surface of the coil is overheated, which will cause the two adjacent wires to short-circuit due to the short circuit of the exposed metal wires, resulting in a low yield of the product. Moreover, the electric hot air blowing and heating coil can only heat and solidify the wire on the surface of the coil, while the wire inside the coil is not heated and solidified, resulting in problems such as incomplete coil solidification, loose coil solidification, and loose coil solidification. Summary of the invention

The structural design of the winding member can prepare for the coil winding of the mold core therein, and when the wire is wound around the winding column for a certain number of turns, it can bypass the blocking column and enter the mold core to prepare for winding the coil.

[0006] By adopting the above technical solution, the wire mechanism can move the wire anywhere in the three-dimensional space through the three-dimensional linear module, so that the wire mechanism can lead the wire to the first wire clamping and energizing device under the drive of the three-dimensional linear module.

When the wire mechanism leads the wire to the winding mechanism, the mold adjustment mechanism closes the coil skeleton and adjusts the width of the inner groove of the skeleton to control the width of the wound coil; then, the winding mechanism winds the coil. After the coil is wound, the wire mechanism clamps the wire tail of the coil to prevent the wire from being pulled out of the wire mechanism by the tensioner after the subsequent second wire clamping and energizing device cuts the wire. Next, the second wire clamping and energizing device cuts and breaks the wire tail of the coil respectively (the breaking point is between the cutting point and the coil), so that the wire inside the enameled wire can be connected and energized with the second wire clamping and energizing device. Next, the positive and negative poles of the external power supply of the first and second wire clamping and energizing devices are energized to energize the coil. After the coil is energized, it will heat up, so that the insulation layer on the wire of the coil is heated and melted, thereby achieving the solidification of the coil.

When the two clamping arms on the third clamping finger cylinder close, they can drive the first blade to break the insulation layer of the wire.

Wherein, the first motor is a winding motor, and the second motor is a demoulding motor.

[0019] By adopting the above technical solution, when the mold adjustment mechanism needs to close the mold, the second motor drives the demoulding mounting plate to move forward (i.e., move in the direction of the first baffle) through the screw bearing assembly, and the demoulding mounting plate drives the demoulding bearing to move forward. Since the core sleeve and the spring sleeve are both installed at the same end of the demoulding bearing, the core sleeve and the spring sleeve can move forward together with the movement of the demoulding bearing. The forward movement of the core sleeve can drive the baffle reset spring to move forward synchronously, and the baffle reset spring drives the spring retaining ring to move forward synchronously, and the spring retaining ring drives the demoulding sleeve and the second baffle to move toward the first baffle together to limit the width of the wound coil.

The method can fully automatically customize the thickness of the coil and has the advantages of high coil winding efficiency, good effect and low cost.

[0049] In one of the embodiments, the first winding spindle 27 is provided with a winding member 9, which includes a spindle clamping member 91 clamped on the first winding spindle 27, a winding frame 92 is provided on the spindle clamping member 91, a winding column 93 for hanging and winding feet to fix the wire ends is provided on the winding frame 92, and a wire blocking column 94 for blocking the bending of the wire is provided on the spindle clamping member 91.

[0050] In one of the embodiments, the working principle of the fully automatic winding machine for the stator coil of the linear motor is as follows: the wire mechanism 4 can be moved to any position in the three-dimensional space through the three-dimensional linear module 3, and when the three-dimensional linear module 3 drives the wire mechanism 4 to lead the wire to the first wire clamping and electrifying device 5, the slide cylinder 52 in the first wire clamping and electrifying device 5 drives the third clamping finger cylinder 53 to move to the side of the winding member 9; when the wire mechanism 4 leads the wire into the first wire clamping and electrifying device 5, the third clamping finger cylinder 53 in the first wire clamping and electrifying device 5 drives the first clamping arm 54 and the second clamping arm 55 thereon to close and clamp the front end of the wire, and when the first clamping arm 54 and the second clamping arm 55 are closed, the first blade 56 on the second clamping arm 55 can break the insulation layer of the wire, so that the wire inside the enameled wire can be electrically connected to the second clamping arm 55 and the first blade 56 in the first wire clamping and electrifying device 5.

[0051] When the wire guide mechanism 4 leads the wire to the winding member 9, the guide pin 45 of the wire guide mechanism 4, driven by the three-dimensional linear module 3, first leads the wire material around the winding column 93 in the winding member 9 to hang the wire and then leads the wire material around the wire blocking column 94, and finally leads the wire to the winding mechanism 2. At the same time, the two clamping arms in the first wire clamping and power-on device 5 release the clamping of the wire end, preparing for the winding mechanism 2 to wind the coil.

[0052] A mold closing adjustment mechanism 7 is provided on the winding mechanism 2. When the second motor 71 in the mold closing adjustment mechanism 7 drives the demoulding mounting plate 72 to move forward (i.e., move toward the direction of the first baffle plate 29) through the screw bearing assembly 75, the demoulding mounting plate 72 can drive the demoulding bearing 209 to move forward. Since the core sleeve 204 and the spring sleeve 208 are both installed at the same end of the demoulding bearing 209, the core sleeve 204 and the spring sleeve 208 can move forward with the movement of the demoulding bearing 209. The forward movement of the core sleeve 204 can drive the baffle plate reset spring 206 to move forward synchronously. The forward movement of the baffle plate reset spring 206 can drive the spring retaining ring 207 to move forward synchronously. The forward movement of the spring retaining ring 207 can drive the demoulding sleeve 205 and the second baffle plate 210 to move toward the direction of the first baffle plate 29 for mold closing. The distance between the second baffle plate 210 and the first baffle plate 29 is the width of the wound coil. The three-dimensional linear module 3 drives the wire mechanism 4 to arrange the wires on the skeleton formed by the first baffle 29 and the second baffle 210 after the mold is closed. When the first motor 22 in the winding mechanism 2 rotates, the first pulley kit 28 can drive the first winding spindle 27 and the transmission shaft 21 to rotate synchronously respectively, and when the transmission shaft 21 rotates, the second pulley kit 212 can drive the second winding spindle 203 to rotate synchronously, that is, the first winding spindle 27 and the second winding spindle 203 can rotate synchronously together under the drive of the first motor 22 to drive the first baffle 29, the mold core 215 and the second baffle 210 to wind the wire until the coil is wound. The mold closing adjustment mechanism 7 can realize the mold closing of the coil skeleton and adjust the width of the inner groove of the skeleton to control the width of the wound coil.

[0053] When the coil is wound, the three-dimensional linear module 3 drives the wire mechanism 4 to lead the wire across the first baffle 29 or the second baffle 210 to shape the wire end of the coil, preventing the wire from being cut by the second wire clamping and energizing device 6 and then being pulled out of the wire mechanism 4 by the tensioner used in conjunction with the winding machine.

[0054] The first wire clamping and power-supplying device 5 clamps the end of the wire again. When the third clamping finger cylinder 53 in the first wire clamping and power-supplying device 5 drives the first clamping arm 54 and the second clamping arm 55 to close, the first blade 56 can break the insulation layer of the wire under the drive of the first clamping arm 54 and the second clamping arm 55 to close, so that one of the electrodes (such as the positive electrode or the negative electrode) of the external power supply of the first wire clamping and power-supplying device 5 can be connected to the wire through the second clamping arm 55 and the first blade 56.

[0055] When the fourth clamping finger cylinder 65 in the second wire clamping and power-supplying device 6 moves downward under the drive of the first cylinder 61, the wire tail can be located in the third clamping arm 66 and the fourth clamping arm 67 in the second wire clamping and power-supplying device 6; when the fourth clamping finger cylinder 65 drives the third clamping arm 66 and the fourth clamping arm 67 to close, the second blade 68 on the third clamping arm 66 can cut the wire, and the third blade 69 on the fourth clamping arm 67 can break the insulation layer of the wire tail exposed outside the coil, so that the other electrode (such as the negative electrode or the positive electrode) of the external power supply of the second wire clamping and power-supplying device 6 can be connected to the wire through the fourth clamping arm 67 and the third blade 69. When the external power supply is powered on, current will pass through the wound coil. The wire of the coil will be energized, which will heat the insulation layer of the wire in the coil. The insulation layers of the two adjacent wires will melt due to the heat and stick together, so that the wound coil can be solidified and formed firmly after being powered on and heated, and the coil can be completely solidified. This avoids the problem that the insulation layer of the wire on the surface of the coil is easily heated and melted, which may cause a short circuit between the two adjacent wires.

[0056] When the coil is energized and solidified, the second motor 71 drives the demoulding mounting plate 72 to retreat (i.e., move in the direction away from the first baffle 29) through the screw bearing assembly 75. The demoulding mounting plate 72 retreats to drive the demoulding bearing 209 to retreat synchronously. The demoulding bearing 209 retreats to drive the core sleeve 204 and the spring sleeve 208 to retreat together. The spring sleeve 208 retreats to drive the baffle plate return spring 206 to retreat synchronously. The baffle plate return spring 206 retreats to drive the spring retaining ring 207 to further drive the demoulding sleeve 205 to retreat, so that the second baffle plate 210 and the core 215 can retreat together with the demoulding. The sleeve 205 retreats and simultaneously retreats in the direction away from the first baffle 29. During the retreat process, the second baffle 210 cannot continue to move in the direction away from the first baffle 29 due to the obstruction of the demoulding fork plate 76, so that the core 215 is driven by the demoulding bearing 209, the demoulding connecting ring 211, the second winding spindle 203, the core connecting rod 213 and the core mounting seat 214 to retract into the second baffle 210, so as to remove the restriction on the coil width, so that the wound coil can be separated from the core 215 and automatically fall into the discharge chute 8, and the material is discharged and recovered through the discharge chute 8.

[0057] Its overall structural design enables a series of operations such as automatically conducting wires on the skeleton, clamping the enameled wire and conducting electricity, leading the wires, arranging the wires, winding the wires, hanging the wires, closing the molds, winding the wires, cutting the wire tails of the coils, clamping the wire tails of the coils and conducting electricity, heating and curing the coils, opening the molds for the wound coils and unloading and recycling the finished coils on one device. The coils wound by using it have the advantages of complete curing, solid curing molding, good curing molding effect, firm coil winding and high product yield. It effectively solves the problems of the winding machines on the market that use electric hot air to heat the coils to form the coils, resulting in the coils having unstable curing molding, incomplete curing, unstable curing and low yield.

Any technical solution that is identical or equivalent to the content described in the claims of the present invention should be included in the protection scope of the present invention.
