[0056] The working principle of this utility model:

[0057] When starting work, the coil is placed on the pallet, and the alignment block 30 aligns the coil to be coated to ensure that the coils are in the same position. The forward cylinder 43 runs to drive the first wire pressing block 34 to the top of the coil. The first wire pressing cylinder 31 descends to make the first wire pressing block 34 press one side of the coil. At the same time, the clamping cylinder 36 retracts to make the clamping block 40 clamp the other side of the coil. Then the second wire pressing cylinder 44 descends, and the second wire pressing block 39 presses the coil.

[0058] The tape clamp 12 rises under the action of the clamp lifting cylinder 22, the tape clamp 12 clamps the tape, the cover plate 4 is opened under the action of the cover plate cylinder 16, the clamp lifting cylinder 22 descends, the tape clamp 12 pulls out a certain length of tape, and the third support plate 18 moves to the right under the action of the support plate cylinder 15 to press against the tape to prevent the tape from escaping from the tape clamp 12 when the coil is being coated. At the same time, the grating ruler 21 detects whether the tape is pulled out normally, and the forward and backward moving module 24 drives the coating device 3 to approach the coating area of ​​the coil. The coil pushes the tape close to the rubber band 25, and the support plate cylinder 15 moves to the left. At the same time, the cover plate 4 presses the tape, and the cutter 5 cuts the tape under the action of the cutter cylinder 7;

[0059] The rubber band 25 on the taping ring is close to the coil, and the rotary motor 19 rotates, driving the taping ring to rotate. The rubber band 25 wraps the tape around the coil. After the taping ring rotates to the gap, the forward and backward movement module 24 drives the taping machine away from the coil, completing the taping process. The left and right movement module drives the taping machine to switch to the coil taping area, and then the taping process is repeated.
