Description

Technical Field

[0001] The utility model relates to the technical field of coil manufacturing, in particular to a coil tape wrapping machine. Background Art

[0002] A coil refers to a ring-shaped wire winding. The most common coil applications include: motors, inductors, transformers, and loop antennas. In the production and processing of some wireless charging coils, three-layer insulated wire inductors, and film-wrapped wire inductors, it is necessary to wrap the outside of the coil with high-temperature tape to meet the product requirements of the coil.

[0003] At present, the conventional way of wrapping tape is that the operator holds the tape in one hand, wraps the tape around the outer surface of the coil with the other hand, and finally cuts the tape with a blade. This manual tape wrapping operation is inefficient, so a coil tape wrapping machine for wrapping coils with tape has emerged. The existing coil tape wrapping machine generally includes a tape clamping mechanism for clamping and pulling the tape, which is used to straighten the tape falling from the feeding direction to facilitate subsequent processes such as cutting the tape and wrapping the tape. However, the existing tape clamping mechanism is usually a cylinder mechanism. Since the cylinder mechanism is generally used for simple linear motion control, its speed is relatively slow and its accuracy is relatively low. When pulling the tape, the pulling length cannot be adjusted arbitrarily and accurately, resulting in the inability to cope with the problem of different tape lengths for coils of various sizes, and the versatility is poor.

The rear end of the horizontal block 522 is fixedly connected to the vertical block 521, the rear clamping block 53 and the front clamping block 54 are located between the guide opening 10 and the horizontal block 522, the front clamping block 54 is fixedly arranged, the rear clamping block 53 and the front clamping block 54 are arranged in parallel and spaced apart, and a clamping gap 70 is formed between the two for the tape 300 to pass through, one end of the slide bar 55 is slidably connected to the front end of the horizontal block 522, and the other end is fixedly connected to the rear clamping block 53, and the blade 56 is horizontally fixed to the bottom of the front end of the horizontal block 522. When the clamping and cutting tape mechanism 5 is working, the guide rod cylinder 51 drives the L-shaped connecting block 52 to move left and right. When the L-shaped connecting block 52 moves to the left (i.e., toward the coil fixture 8), the rear clamping block 53 and the front clamping block 54 clamp the tape 300, the L-shaped connecting block 52 slides along the slide bar 55, and the blade 56 at the bottom of the horizontal block 522 moves horizontally to cut the tape 300.

[0029] The tape shaping mechanism 6 includes an upper push plate 61, a lower push plate 62 and a shaping drive device 63. The upper push plate 61 and the lower push plate 62 are horizontally arranged and parallel to each other. A shaping gap 20 that matches the thickness of the coil 200 is formed between the front ends of the upper push plate 61 and the lower push plate 62.

When the upper push plate 61 and the lower push plate 62 move to the left (i.e., toward the guide opening 10 of the coil fixture 8), due to the existence of the shaping gap 20, the L-shaped push-pull portion 621 at the front end of the upper push plate 61 and the front end of the lower push plate 62 pushes the tape 300 to fit the tape 300 with the coil 200. The tape bending mechanism 7 pushes the tape 300 that has passed the inner circle of the coil 200 to ninety degrees, and the upper push plate 61 and the lower push plate 62 move back to the right.

[0033] First, the coil 200 is placed on the positioning column 9 of the coil fixture 8; secondly, the coil tape wrapping machine is started, the tape clamping motor mechanism 4 clamps the tape 300 and pulls it to the set position, the tape clamping and cutting mechanism 5 cuts the tape 300, and the tape shaping mechanism 6 moves toward the guide opening 10 of the coil fixture 8 to fit the tape 300 and the coil 200; then, the tape bending mechanism 7 pushes the tape 300 that has passed the inner circle of the coil 200 to ninety degrees; finally, when the tape shaping mechanism 6 is retracted, the tape 300 at ninety degrees is fitted to the coil 200.
