Description

Technical Field

[0001] This utility model relates to the field of welding wire production technology, specifically a defective welding wire rewinding device. Background Technology

[0002] In the production process of solid core welding wire, the finished wire must be inspected at the end. Occasionally, some welding wires will fail to pass the copper plating test. This is because during the continuous processing of welding wire, a machine stoppage occurs, causing the welding wire to be soaked in acid or alkali solution for too long, which prevents the subsequent copper plating from forming a proper coating. For these defective products, the welding wires need to be reworked. However, the finished wires are wound on small spools with limited length. If rework is carried out directly, frequent feeding is required, which is not suitable for continuous operation. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0022] To address the problems existing in the relevant prior art, this utility model proposes a defective welding wire rewinding device. The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-3 The following specific embodiments are provided:

[0024] Example 1:

[0025] A defective welding wire rewinding device includes an unwinding frame 1 for fixing a small spool of welding wire, a drawing die 3 for lubricating the welding wire 2, a winding spool 4, a wire laying machine 5, and a take-up mechanism 6.

[0026] The unwinding frame 1 includes a tension shaft 101 and a fixing frame 102 for fixing the tension shaft 101. When in use, the small coil of welding wire is fixed on the tension shaft 101. The tension shaft 101 can be a conventional air tension shaft and does not provide power. The traction power is provided by the final take-up mechanism.

[0027] The drawing die box 3 specifically includes a box body 301, a drawing die head 302 fixed inside the box body 301, and a lubricant 303 placed inside the box body 301. Holes are provided at both ends of the box body. During use, the welding wire enters the box body 301 through one hole, the lubricant 303 adheres to the surface of the welding wire, and then passes through the drawing die head 302 and exits through the hole at the other end of the box body 301. The drawing die head 302 is an existing design and is not specifically limited here. In actual use, the drawing die head can be selected to be smaller than the diameter of the welding wire, so that the welding wire can be further reduced in diameter during the wire drawing process, forming a smaller welding wire. For example, when the diameter of the unqualified finished wire is 2.0mm, the drawing die head with a diameter of 1.6mm can be selected. This reduction in diameter also facilitates the subsequent removal of the original coating for secondary copper plating.

[0028] The receiving mechanism 6 includes a frame 601, a rotating shaft 602, a first motor 603, and an I-beam wheel 604. The first motor 603 drives the rotating shaft 602 to rotate and is belt driven. The first motor 603 and the rotating shaft 602 are fixed on the frame 601. The I-beam wheel 604 is fixed on the rotating shaft. The first motor 603 drives the I-beam wheel 604 to rotate. In the specific working process, the I-beam wheel 604 is a commonly used workpiece in the workshop. The number of welding wires that can be wound on each I-beam wheel 604 is more than the number of finished wires that can be wound on the spool. That is, multiple unqualified finished wires can eventually be wound onto the same I-beam wheel 604.

[0029] In practical use, first, the unqualified finished wire spool is fixed on the expansion shaft 101. The head of the welding wire 2 is passed through the drawing die box 3, and then the welding wire is wound several times on the winding reel 4. Finally, the end of the welding wire is passed through the wire laying machine 5 and fixed on the I-beam wheel 604. The wire laying machine is an existing design and is not specifically limited here. Then, the first motor 603 drives the I-beam wheel 604 to rotate, pulling the welding wire to wind onto the I-beam wheel 604. After one unqualified finished wire is wound, the empty spool needs to be removed, and another finished wire needs to be fixed on the expansion shaft 101. Repeat the above operation, and connect the next finished wire with the previous finished wire. Continue repeating the above operation until the I-beam 604 is full of defective wire. Then remove the I-beam 604 from the shaft 602 and return it to the copper plating line for secondary copper plating. By rewinding multiple defective finished wires onto the same larger I-beam and connecting them, it can be adapted to the existing continuous production line. At the same time, lubrication and wire arrangement are carried out during the rewinding process, which effectively prevents breakage and facilitates subsequent secondary processing, reducing waste.

[0030] Example 2:

[0031] The difference from Embodiment 1 is that it also includes a machine base 7, with the drawing die box 3 and winding disc 4 fixed on the machine base 7. A guide wheel 8 is also provided on the end of the machine base 7 near the wire drawing machine 5. The machine base 7 is also equipped with a wire welding mechanism 9, which specifically includes a welding table 901. The welding table 901 has two wire clamps 902, one fixed to the welding table 901 and the other connected to the welding table 901 via a first slide rail 903, allowing the two wire clamps 902 to slide towards or away from each other. A power supply 904 for supplying power to the wire clamps 902 is also provided at the lower part of the welding table 901.

[0032] The welding wire clamp 902 includes an upper clamping plate 9021, a lower clamping plate 9022, and a torsion spring. The upper clamping plate 901 is made of ceramic, and the lower clamping plate 9022 is made of copper. The power supply 904 is connected to the lower clamping plate 9022. During the actual welding process, the two ends of the welding wire are clamped by the two welding wire clamps 902 respectively to ensure that the two ends are aligned. Then, the power supply is turned on, and the welding wire clamps 902 connected to the first slide rail 903 are pushed to make the two ends fit tightly together, thereby achieving the welding connection.

[0033] The upper part of the welding station 901 is also equipped with a grinding wheel 905, and the lower part of the welding station 901 is equipped with a second motor 906 that drives the grinding wheel 905 to rotate. After the welding is completed, the welding wire will melt and solidify at the connection. Therefore, the connection can be ground smooth by the grinding wheel 905, which is convenient for subsequent drawing through the drawing die 302.

[0034] The machine base 7 is equipped with a second slide rail 10, the direction of which is perpendicular to the direction of the welding wire 2. The welding wire docking structure 9 is connected to the second slide rail 10 by a slider and can slide along the second slide rail 10. Specifically, when welding is required, the welding wire docking mechanism 9 is slid to the bottom of the welding wire 2 for easy docking. When docking is not required, the welding wire docking mechanism 9 is slid to the rear for easy movement of the welding wire.

[0035] The cable laying machine 5 includes a frame 501, a guide rod 502, a screw 503, a reversing rod 504, and a base 505. The guide rod 502 and the reversing rod 504 are parallel and both pass through the base 505. The base 505 has an internal thread that mates with the screw 503. One end of the screw 503 is connected to a third motor 506. The third motor 506, the guide rod 502, the screw 503, and the reversing rod 504 are all fixed to the frame 501. The third motor 506 drives the screw to rotate, which in turn drives the base 505 to move along the axial direction of the screw 503. The upper part of the base 505 is provided with two sets of guide wheels 507, which are horizontally and vertically arranged respectively. The welding wire passes through the middle of the two sets of guide wheels 507. The reversing rod 504 and the base 505 are respectively provided with... The system includes a cooperating position signal transmitter and receiver, and is equipped with a servo control system. The transmitter and receiver control the direction of the third motor 506 to change direction. Specifically, there are two receivers, both fixed on the reversing rod 504, and one transmitter, fixed on the unit, with the transmitter 1 located between the two receivers. The third motor 506 drives the screw to rotate, thereby moving the base towards one of the receivers. When the transmitter and receiver transmit signals, the servo system controls the third motor 506 to rotate in the opposite direction, causing the base to move towards the other receiver. When aligned with the other receiver, the base also rotates, causing it to reciprocate between the two receivers. The above control system is existing technology and is only described here for motion purposes, without any specific limitations.

[0036] When the operator notices that the previous coil of welding wire is about to finish rewinding, the traction speed of the first motor 603 is adjusted. When the tail of the previous coil of welding wire stops near the welding wire docking mechanism, the next coil of welding wire is fixed on the expansion shaft 101. At this time, the welding wires are docked through the welding wire docking mechanism 9. This eliminates the need for manual threading of the welding wire head through the drawing die, making the operation more convenient. Other steps are the same as in Embodiment 1 and will not be repeated.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
