DETAILED DESCRIPTION

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0052] A coil has a multi-turn structure, and the shape of the coil includes oval, rectangular, and circular, such as Figure 1 As shown, the coil includes an enameled wire 1 and an enameled wire 2. One end of the enameled wire 1 is a wire end 1, and the other end is a wire tail 1. One end of the enameled wire 2 is a wire end 2, and the other end is a wire tail 2. When the winding starts, the wire ends of the enameled wire 1 and the enameled wire 2 are wound in parallel. After one layer of winding, two turns of the coil are completed. If four turns are required, the enameled wire 1 and the enameled wire 2 are continued to be wound in parallel. After the winding is completed, a four-turn coil is formed. The wire end and the wire tail of the coil are located on the same side of the coil. This method is used for winding a coil with an even number of layers.

[0053] If three turns are required, the enameled wire 1 and the enameled wire 2 are staggered so that the two wires are wound side by side. The completion of the winding is the third turn of the coil. The wire arrangement on the third turn is: enameled wire 1, enameled wire 2, enameled wire 1, ..., enameled wire 2, enameled wire 1. At this time, the wire end and the wire tail of the coil are still on the same side of the coil. This method is a coil winding with an odd number of layers.

[0054] like Figure 2 The figure shows the coil winding of the prior art. A single wire is wound into two layers of coils. Winding an odd number of turns will cause the wire head and tail ends to be located on both sides, making the coil inconvenient to use and unsightly, and not conducive to packaging and transportation. If an even number of turns, such as four turns, is required, the single wire is cut off after being wound into two layers, and another wire is started to continue winding on the two layers of coils. This will cause the wire heads and tail ends of the two wires to be messy, which is not conducive to distinguishing the wire heads and tail ends of each wire during subsequent installation.

The support shaft 40 is rotatably installed on the operating box 32, and the end of the support shaft 40 away from the disk is fixedly provided with an operating lever 403. The support shaft 40 is manually controlled to rotate by the operating lever 403, so that the disk pulls the pull rod 401 to move, pulling the push rod 41 away from the winding rod 44, so as to facilitate the removal of the wound coil.

An electric slide 2 63 is fixed on the movable frame 6, and a movable plate 64 is slidably provided on the electric slide 2 63. The movable plate 64 is fixedly mounted on the electric slider of the electric slide 2 63, and a clamping plate 1 65 is fixed on the movable plate 64.

[0064] A side frame 66 is fixedly provided on one side of the movable plate 64, and a cylinder 2 67 is fixed on the side frame 66. The output end of the cylinder 2 67 is fixedly connected to a clamp 2 68. The clamp 2 68 corresponds to the clamp 1 65 to clamp the wire and suspend the feeding of the wire. A cross bar 69 is fixedly provided at one end of the movable plate 64, and a U-shaped block 60 is fixedly connected to the cross bar 69. A guide rod 601 is fixedly connected inside the U-shaped block 60, and springs 3 602 are fixedly provided on both sides of the guide rod 601.

[0066] like Figure 12 As shown, the wire member 8 includes a sliding plate 1 81 and a sliding plate 2 82, and two wire rollers 83 are rotatably provided on the sliding plate 1 81 and the sliding plate 2 82.

At this time, the spring three 602 is in a pulled-up state. When the output end of the cylinder three 603 contracts, the spring three 602 pulls the sliding plate one 81 or the sliding plate two 82 to move toward the direction close to the U-shaped block 60.

[0068] A mounting block 86 is fixed on the sliding plate 81, and a lifting frame 87 is slidably provided on the mounting block 86.

A cylinder 5 76 is fixedly provided on the top plate 75, and the output end of the cylinder 5 76 is fixedly connected to a U-shaped frame 78, and the two ends of the U-shaped frame 78 are respectively fitted on the top of the two rocker arms 79.

[0074] The U-shaped frame 78 is controlled to move downward by the cylinder five 76, and then the two ends of the U-shaped frame 78 are used to press down the two rocker rods 79, so that the two extension rods 772 move downward, the spring four 771 is compressed, and the pressure rod 774 moves downward, limiting the wire on the roller 74 so that the wire is conveyed in contact with the roller 74. At the same time, after the wound wire is straightened, the two wires are respectively conveyed to the two wire rollers 83 on the sliding plate one 81, and then output from the two wire rollers 83 on the sliding plate two 82 to the winding rod 44.

[0075] Here’s how it works:

[0076] The wire is first passed around the wire conveying roller 72, and then straightened and output from between the pressure rod 774 and the roller 74. The two wires are respectively transported to the two wire rollers 83 on the sliding plate 1 81, and then output from the two wire rollers 83 on the sliding plate 2 82 to the winding rod 44. At this time, the two wires are arranged side by side, and the ends of the two wires are fixed in the wire bundle groove 431. Then, once the motor is started, the two winding rods 44 are driven to rotate through the drive shaft 31 to perform coil winding.

[0077] When winding begins, the ends of enameled wire 1 and enameled wire 2 are wound in parallel. After one layer of winding, two turns of the coil are completed. If four turns are required, the enameled wire 1 and enameled wire 2 are wound in parallel. After the winding is completed, a four-turn coil is formed. The ends and tails of the coils are located on the same side of the coil. This method is used for winding coils with an even number of layers.

[0078] If three turns are required, the enameled wire 1 and the enameled wire 2 are staggered so that the two wires are wound side by side. The completion of the winding is the third turn of the coil. The wire arrangement on the third turn is: enameled wire 1, enameled wire 2, enameled wire 1, ..., enameled wire 2, enameled wire 1. At this time, the wire end and the wire tail of the coil are still on the same side of the coil. This method is a coil winding with an odd number of layers.

[0079] The coils of different layers are wound in the above manner, and then the electric slide 37 controls the electric clamp 38 to move downward, and the electric clamp 38 is used to cut the wire of the coil. At this time, the coil winding is completed, and the output end of the cylinder 35 is moved out of the through slot 34. The cylinder 35 releases the fixation of the push rod 41, and then the joystick 403 is manually rotated. The support shaft 40 is manually controlled to rotate through the joystick 403, so that the disc pulls the pull rod 401 to move, and pulls the push rod 41 away from the winding rod 44, so as to facilitate the removal of the wound coil.

[0080] A coil winding method includes the following steps:

[0081] S1. The wire is transported to the operating table 3, and the wire end is manually fixed on the winding jig 4, and then the winding operation is performed;

[0082] S2. At the beginning of winding, the ends of enameled wire 1 and enameled wire 2 are wound in parallel. After winding one layer, two turns of the coil are completed. The winding method is as follows:

[0083] S2.1. If an even number of turns is required, the enameled wire 1 and the enameled wire 2 are always wound in parallel. After the winding is completed, the coil has an even number of layers.

[0084] S2.2. If an odd number of turns need to be wound, when winding the last turn, the output end of the cylinder 3 603 pushes the push block 604 to move, so that the sliding plate 1 81 moves and is offset from the sliding plate 2 82, so that the enameled wire 1 and the enameled wire 2 are offset, and the two wires are wound side by side. When the winding is completed, it is the last turn of the coil, and the winding of the coil with an odd number of layers is completed.

[0085] S3. After winding is completed, the coil is manually removed to check whether the number of coil turns is qualified, and then sent to the next production process.
