The first cylinder is activated, pushing the rectangular block forward slightly, clamping the end of the flat copper wire. Because the front width of the rectangular block is smaller than the rear width, and the width of the rectangular hole gradually decreases from front to back, the rectangular block experiences a compressive force and slight deformation as it moves forward, reducing the width of the groove and clamping the end of the flat copper wire. Then, the second cylinder is activated, pushing the clamping column backward to press the rectangular block. At this point, the rotating end of the hub motor is initially stationary, and the winding device... Align with the fixed device; start the hub motor and the third cylinder. The rotating end of the hub motor drives the connecting rod 11 to rotate, and the winding device rotates accordingly. Under the drive of the disc, the flat copper wire is wound along the outer perimeter of the rectangular block, gradually forming a coil. During the winding process, the roller moves with the flat copper wire and applies a downward force to the flat copper wire, so that each two adjacent coils are in contact with each other. After the winding is completed, the hub motor stops rotating, the fourth cylinder starts, and the second blade connected to the moving end of the fourth cylinder moves towards the first blade to achieve the cooperation of the first and second blades to cut the flat copper wire. After the cutting is completed, the first, second, third, and fourth cylinders all retract and reset to their initial positions. The wound flat copper coil will fall onto the slide plate.
