Description

Technical Field

[0001] This utility model relates to the field of wire clamp technology, specifically to a wire clamp mechanism for a winding machine. Background Technology

[0002] In the electronics manufacturing industry, magnetic ring induction coils are fundamental components of electronic products. A magnetic ring induction coil is a component consisting of several wires wound around the inner wall of a magnetic ring, forming a circular surface with evenly distributed coils of wire. To improve the winding efficiency of induction coils, winding machines are currently used instead of manual winding. These machines use grippers to pick up the wire and wind it onto the magnetic ring. However, the grippers can easily damage the insulation layer on the wire's surface, affecting its lifespan and even causing short circuits in the coil. Utility Model Content

[0003] This utility model addresses the existing technical problems by providing a wire clamp mechanism for a winding machine.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A wire clamp mechanism for a winding machine includes a clamping cylinder and a first wire clamp and a second wire clamp mounted on the clamping cylinder. The clamping cylinder is used to drive the first wire clamp and the second wire clamp to clamp or release the wire. The first wire clamp is provided with a positioning protrusion, and the second wire clamp is provided with a positioning groove. The positioning groove corresponds to the positioning protrusion. When the first wire clamp and the second wire clamp clamp the wire, a portion of the positioning protrusion is engaged in the positioning groove.

[0005] Based on the above technical solution, the present invention can be further improved as follows:

[0006] Preferably, the first and / or second wire clamps are provided with receiving grooves, and clamping pads are provided in the receiving grooves. The clamping pads are used to provide a certain clamping force for the wire, so that the wire maintains a certain tension during the pulling process, while preventing it from being completely locked.

[0007] Preferably, the positioning protrusion is disposed at the end of the wire clamp, and the positioning protrusion is U-shaped with the opening facing inward.

[0008] Preferably, the outer edge of the positioning protrusion cooperates with the first wire clamp and the second wire clamp to form a space for the wire to pass through.

[0009] Preferably, the first wire clamp has a first inclined surface, and the second wire clamp has a second inclined surface. The first inclined surface and the second inclined surface are adapted to each other. The first inclined surface has a second positioning groove, which is used to position the wire. The second positioning groove can restrict the wire to a suitable position to ensure the clamping effect.

[0010] Preferably, the gripper cylinder is hinged to the support plate via a rotating shaft, and two needle cylinders are mounted on the support plate. The two needle cylinders are located on both sides of the rotating shaft, and the needle cylinders are used to drive the gripper cylinder to swing around the rotating shaft.

[0011] Preferably, the outer edge of the positioning protrusion is a smooth arc surface. This is because during operation, the wire will wrap around the positioning protrusion and experience sliding friction with it. The smooth arc surface design prevents sharp edges from scratching the wire and ensures the wire remains undamaged.

[0012] Preferably, the clamping pad is made of urethane rubber.

[0013] The beneficial effects of this utility model are: by installing clamping pads inside the first and / or second clamps, combined with the control of the movement amplitude of the clamping cylinder, and the limiting effect of the positioning protrusion and the positioning groove, a suitable clamping force can be generated on the wire. This ensures that the clamped wire has a certain tension, while avoiding excessive clamping, which would damage the wire when it cannot be pulled in subsequent processes. Attached Figure Description

Detailed Implementation

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. The terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1 to 6 As shown, this utility model discloses a wire clamp mechanism for a winding machine, including a clamping cylinder 7 and wire clamp 1 and wire clamp 2 mounted on the clamping cylinder 7. The clamping cylinder 7 is used to drive wire clamp 1 and wire clamp 2 to clamp or release the wire. Wire clamp 1 is provided with a positioning protrusion 3 and a receiving groove 5. A clamping pad 6 is installed in the receiving groove 5. The clamping pad 6 protrudes from the receiving groove 5 and plays a role in protecting and clamping the wire, reducing damage to the wire insulation layer and ensuring a suitable clamping force. If it is too loose, the tension of the wire will be insufficient; if it is too tight, the wire will not be properly tensioned. Excessive force applied during the wire pulling process can easily damage the wire. The wire clamp 2 has a positioning groove 4, which corresponds to the positioning protrusion 3. The thickness of the positioning protrusion 3 is greater than the depth of the positioning groove 4. This ensures that when wire clamps 1 and 2 are in the clamping state, a portion of the positioning protrusion 3 remains exposed, allowing the wire to wrap around it. This serves two purposes: firstly, it constrains and limits the wire; secondly, the smooth outer surface of the positioning protrusion 3 prevents the wire from being bent at large angles, ensuring its safety. When wire clamps 1 and 2 are closed, the distance between the clamping pad 6 and wire clamp 2 is less than the wire diameter, thus clamping the wire.

[0024] In this embodiment, the clamping pad 6 is specifically made of urethane. Urethane has good flexibility, which improves the protection of the wire.

[0025] In an optional embodiment, the clamping pad 6 may be made of wool felt, which is soft and can provide good cushioning for the wire, reduce damage caused by friction, and ensure the service life of the wire.

[0026] In an optional embodiment, the receiving groove 5 and the clamping pad 6 can also be disposed on the wire clamp 2, which can also achieve the function of clamping the wire.

[0027] In this embodiment, the positioning protrusion 3 is disposed at the end of the wire clamp 1. The outer edge of the positioning protrusion 3 is a smooth arc surface; specifically, the positioning protrusion 3 is U-shaped with the opening facing inward. The arc-shaped end of the positioning protrusion 3 can reduce wire bending, thereby reducing the damage to the wire caused by bending.

[0028] Furthermore, the outer edge of the positioning protrusion 3 cooperates with the first wire clamp 1 and the second wire clamp 2 to form a space for the wire to pass through. The first wire clamp 1 and the second wire clamp 2 limit the wire, preventing the wire from shifting during winding, ensuring that the hook 14 can properly hook the wire and wrap it around the magnetic ring 15.

[0029] In this embodiment, specifically, the wire clamp 1 has a bevel 11, and the wire clamp 2 has a bevel 12. The bevel 11 and the bevel 12 are adapted to each other. The bevel 11 has a positioning groove 13 for positioning the wire. The bevel 11 extends along the length of the wire clamp 1, and the bevel 12 extends along the length of the wire clamp 2. Through the cooperation of the bevel 11 and the bevel 12, the wire clamp 1 and the wire clamp 2 are guided, ensuring that the wire clamp 1 and the wire clamp 2 can close normally to grip the wire.

[0030] Furthermore, the end of the positioning protrusion 3 near the positioning groove 13 is rounded, which protects the wire and prevents the sharp edge from damaging the wire.

[0031] In this embodiment, specifically, the gripper cylinder 7 is hinged to the support plate 9 via the rotating shaft 8. Two needle cylinders 10 are mounted on the support plate 9. The two needle cylinders 10 are located on both sides of the rotating shaft 8. The needle cylinders 10 are used to drive the gripper cylinder 7 to swing around the rotating shaft 8. Thus, even without the external mechanism moving, the gripper itself can swing within a small range to meet the position control requirements between multiple coils.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
