Abstract
Description
Technical Field
[0001] The present application relates to the field of copper wire feeding devices, and in particular to a copper wire feeding device with adjustable tensile strength. Background Art
[0002] After the semi-finished copper wire is manufactured, it is often bent and wound around a turntable to form a coil. The coil then undergoes electroplating, requiring a wire feeder to pull the coiled wire and guide it into the plating bath. Since the diameter of copper wire typically ranges from 0.6mm to 1.2mm, the wire feeder's tensile force during feeding should be neither too strong nor too weak, as this could cause the wire to break.
[0003] The tensile strength required for copper wires of various diameters is often different, and the tensile strength of the copper wire in common wire feeding devices is often fixed or preset to several values, which makes it difficult to meet the tensile strength requirements of copper wires of various diameters.

[0028] Reference Figure 1-4 ,
[0029] A copper wire feeding device with adjustable tensile strength comprises: a frame 2, a first guide wheel 3, a second guide wheel 4, a rocker arm 5, a power member 6, and a drive assembly 7. The frame 2 is placed on the ground, and the lower portion of the frame 2 forms a accommodating chamber for accommodating a copper wire roll 1. The first guide wheel 3 is rotatably connected to the upper end of the frame 2 via a bearing, and the second guide wheel 4 is located below the first guide wheel 3. The second guide wheel 4 is rotatably connected to the end of the rocker arm 5 away from the copper wire roll 1 via a bearing. The copper wire in the copper wire roll 1 passes through the first guide wheel 3 and the second guide wheel 4 in sequence before entering the electroplating tank for the next step. The first guide wheel 3 and the second guide wheel 4 guide and tighten the copper wire. The power element 6 is a first motor, and its output end is bolted to the middle of the pendulum 5. When the power element 6 rotates, it drives the two ends of the pendulum 5 to rotate in a plane perpendicular to the ground, raising and lowering the height of the second guide wheel 4, thereby changing the distance between the second guide wheel 4 and the first guide wheel 3, and thus controlling the tension of the copper wire by the first and second guide wheels 3 and 4. Because the rotation of the pendulum 5 is continuous, the adjustment of the tension of the copper wire is also continuous, which can accommodate a variety of copper wire diameters. The drive assembly 7 is mounted on the frame 2 and is used to rotate the copper wire reel 1 in the frame 2 to continuously feed the copper wire.
[0030] Specifically, the system further includes a push-pull member 8 and a first plug 9. A receptacle is formed at each end of the wire coil 1. The push-pull member 8 utilizes a pneumatic cylinder. The first plug 9 extends through one side of the frame 2 and is slidably connected to the frame 2. The output end of the push-pull member 8 is bolted to the end of the first plug 9 facing away from the wire coil 1. The other end of the first plug 9 faces one of the receptacles in the wire coil 1 and rotates with it. The other receptacle in the wire coil 1 is connected to the drive assembly 7. The push-pull member 8 reciprocates the first plug 9 along the axial direction of the wire coil 1. When the push-pull member 8 brings the first plug 9 closer to and into the receptacle in the wire coil 1, the first plug 9 and the drive assembly 7 cooperate to support the wire coil 1. As the drive assembly 7 rotates the wire coil 1, the wire coil 1 rotates against the first plug 9, causing friction. When the push-pull member 8 moves the first plug 9 away from the receptacle, the support on one side of the wire coil 1 is released, allowing a worker to remove the wire coil 1 from the drive assembly 7.
[0031] Specifically, two sets of first guide wheels 3 are arranged at the same height. One set of first guide wheels 3 is located directly above the second guide wheels 4, with the ground projection of the second guide wheels 4 spaced apart from the ground projection of the copper wire coil 1. The other set of second guide wheels 4 is located above the copper wire coil 1. The copper wire first passes upward around the first set of first guide wheels 3 above the copper wire coil 1, then around the other set of guide wheels, and finally turns downward around the second guide wheels 4.
[0032] Specifically, the device further includes a counterweight 10. The counterweight 10 is welded to the end of the pendulum 5 away from the second guide wheel 4. After the power element 6 rotates the pendulum 5 to a certain angle, the power element 6 stops. If the copper wire bounces during transportation, it will exert pressure on the pendulum 5, causing it to swing. The counterweight 10 can quickly stabilize the pendulum 5, thereby quickly alleviating the copper wire's bounce and stabilizing it.
[0033] Specifically, the frame 2 further includes two sets of limit posts 11, both of which are welded to the frame 2. One set of limit posts 11 is located above the swing arm 5, and the other set of limit posts 11 is located below the swing arm 5. The swing arm 5 swings between the two sets of limit posts 11. The two sets of limit posts 11 limit the end of the swing arm 5 connected to the second guide wheel 4 to rotate within a sector. The included angle of the sector is 30 degrees, preventing the swing arm 5 from rotating too much and causing the second guide wheel 4 to separate from the copper wire.
[0034] Specifically, the drive assembly 7 includes: a rotary drive member 12, a first pulley 13, a belt 14, a second pulley 15, and a second plug 16. The rotary drive member 12 uses a second motor. The housing of the rotary drive member 12 is fixedly connected to the frame 2 via bolts. The output end of the rotary drive member 12 is fixedly connected to the first pulley 13 via a flat key. The second pulley 15 is fixedly connected to the end of the second plug 16 away from the copper wire roll 1 via a flat key. The other end of the second plug 16 is inserted into the socket of the copper wire roll 1 and fixed relative to the copper wire roll 1. The second plug 16 extends through the side of the frame 2 opposite the first plug 9 and is rotatably connected to the frame 2 via a bearing. The belt 14 is sleeved onto the first pulley 13 and the second pulley 15. The first pulley 13 and the second pulley 15 have the same diameter. The output end of the rotating drive member 12 rotates to drive the first pulley 13 to rotate, the first pulley 13 drives the belt 14 to rotate, the belt 14 drives the second pulley 15 to rotate, the second pulley 15 drives the second plug 16 to rotate, and the second plug 16 drives the copper wire roll 1 to rotate around its own axis to deliver the copper wire.
[0035] Specifically, it also includes a protective cover 17. The protective cover 17 surrounds the first pulley 13, the belt 14 and the second pulley 15, and is mounted on the frame 2 by bolts to prevent the first pulley 13, the belt 14 and the second pulley 15 from rotating at high speed from injuring people.
