[0002] In modern industrial production, automatic coil winding machines are widely used in electronics, electrical appliances, motors, and other fields to efficiently and accurately complete the winding of various coils. During the coil winding process, stable control of wire tension plays a crucial role in ensuring coil winding quality, improving production efficiency, and ensuring the normal operation of the equipment. Excessive wire tension can easily lead to wire breakage or deformation, affecting the coil's performance and appearance; insufficient tension can result in loose winding, uneven arrangement, and reduced electrical performance and mechanical strength of the coil.

[0003] Existing tension control devices for winding machines lack effective adjustment mechanisms when guiding wires of different thicknesses. When changing wire specifications, it is necessary to frequently replace the guiding components, which is cumbersome and not only reduces production efficiency but also increases production costs.

[0004] Therefore, this utility model provides a tension control device for an automatic coil winding machine to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see Figure 1-4A tension control device for an automatic coil winding machine includes a worktable 1. A first support plate 2 is fixedly installed at the front and rear edges of the top left side of the worktable 1. A limiting mechanism is installed on the first support plate 2. A second support plate 14 is fixedly installed at the front and rear edges of the top right side of the worktable 1. A second rotating shaft 15 is rotatably installed between the two sets of second support plates 14. A winding coil 17 is symmetrically fixedly installed on the second rotating shaft 15. A second motor 16 is fixedly installed on the outer wall of one set of second support plates 14. The output end of the second motor 16 is fixedly connected to the second rotating shaft 15.

[0023] The limiting mechanism includes a first rotating shaft 3, mounting strip 4, mounting rod 5, fixed baffle 6, mounting cavity 7, movable baffle 10, and a first bidirectional lead screw 11. The first rotating shaft 3 is rotatably mounted on one end of each of the two sets of first support plates 2 that are close to each other. The mounting strip 4 is fixedly mounted on one end of each of the two sets of first rotating shaft 3 that are close to each other. The mounting rod 5 is fixedly mounted on the edge of each end of the two sets of mounting strip 4. Two sets of fixed baffles 6 are symmetrically fixedly mounted on each set of mounting rod 5. The movable baffle 10 is slidably mounted on the outer wall of each end of each set of mounting rod 5. The mounting cavity 7 is opened inside each of the two sets of first rotating shaft 3. The first bidirectional lead screw 11 is rotatably mounted inside each set of mounting cavity 7.

[0024] The limiting mechanism also includes sliders 8, through slots 9, a first rotating head 12, and a first motor 13. Two sets of sliders 8 are symmetrically slidably installed inside the two sets of mounting cavities 7. Two sets of through slots 9 are longitudinally symmetrically opened on the two sets of mounting rods 5. Each set of through slots 9 is connected to the mounting cavity 7 at the corresponding position. Each set of sliders 8 passes through the through slot 9 and is fixedly connected to the movable baffle 10 at the corresponding position. Each set of sliders 8 is threadedly connected to the first bidirectional lead screw 11 at the corresponding position. The front ends of the two sets of first bidirectional lead screws 11 extend to the outside of the mounting strip 4 and are fixedly installed with the first rotating head 12. The first motor 13 is fixedly installed on the outer wall of one set of first support plates 2. The output end of the first motor 13 is fixedly connected to the first rotating shaft 3 at the corresponding position. The first motor 13 is a self-locking motor, and the second motor 16 is a servo motor.

[0025] When using this device to wind wire, such as Figure 1As shown, the wire passes through the limiting mechanism in an S-shape. The slider 8, slidably installed inside the mounting cavity 7, is not only threadedly connected to the first bidirectional lead screw 11 but also fixedly connected to the corresponding movable baffle 10. The operator can rotate the first rotating head 12 according to the wire's diameter, causing the first bidirectional lead screw 11 to rotate and adjusting the distance between the movable baffle 10 and the fixed baffle 6. This allows for simultaneous winding of two sets of wires and enables limiting and guiding of wires of different specifications without replacing the guide components. This allows for efficient and precise winding of various coils, enhancing the device's practicality. The operator can then adjust the angle between the two mounting rods 5 by activating the first motor 13, thereby adjusting the tension of the wire as it passes through the limiting mechanism in an S-shape, thus improving the winding quality. After adjustment, the operator can activate the second motor 16 to drive the winding coil 17 to wind the wire.

Both sets of support seats 21 are threadedly connected to the second bidirectional screw 20. The front end of the second bidirectional screw 20 extends to the outside of the mounting groove 19 and is fixedly installed with a second rotating head 23. Rubber pads 24 are fixedly installed at the four corners of the bottom of the workbench 1.

[0028] After the wire passes through the limiting mechanism and before winding, the wire can be passed through the set guide wheel 22. Then, the operator can adjust the position of the two sets of guide wheels 22 by rotating the second rotating head 23 according to the actual situation, thereby further improving the quality of wire winding.
