Description

Technical Field

[0001] This utility model relates to the field of copper wire straightening technology, and in particular to a fully automatic straightening device for the production of tin-plated copper wire. Background Technology

[0002] Tinned copper wire refers to copper wire with a thin layer of tin plated on its surface, forming a new type of wire material. Compared with traditional copper wire, tinned copper wire has better corrosion resistance and wear resistance, which can effectively extend the service life of the wire. Therefore, tinned copper wire has been widely used in construction, communication, transportation and other fields. However, during the production process, copper wire may bend or have residual stress due to raw material problems, storage and transportation, processing and other reasons, which will lead to a decrease in subsequent processing accuracy, reduced product reliability or automated production jams. Therefore, tinned copper wire straightening equipment has become an indispensable link in copper wire processing.

[0003] Traditional straightening devices for tin-plated copper wire often employ fixed roller sets or die stretching methods. However, on the one hand, when using fixed roller sets, the roller spacing remains constant, making it difficult to flexibly adjust the straightening pressure for tin-plated copper wires of different diameters. For thinner tin-plated copper wires, excessive pressure can easily deform them, affecting product quality; while for thicker tin-plated copper wires, insufficient straightening pressure cannot achieve the desired straightening effect. On the other hand, although die stretching can straighten the copper wire to some extent, the high tension applied during the straightening process can easily cause the tin plating layer to peel off, severely affecting the conductivity of the tin-plated copper wire and reducing product performance. In addition, traditional straightening devices are usually structurally complex, with inconvenient connections and disassemblies between components. Especially when vulnerable parts such as rollers need to be replaced, a significant amount of time is often required to disassemble the entire assembly, resulting in long downtime, greatly impacting production efficiency and increasing production costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fully automatic straightening device for the production of tin-plated copper wire, which aims to improve the problems of low straightening accuracy, easy damage to the plating layer and poor adaptability to multiple wire diameters, while improving production efficiency and ease of operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic straightening device for producing tin-plated copper wire, comprising a worktable, a CNC table fixedly connected to one side of the worktable, a base fixedly connected to the upper surface of the worktable, a housing fixedly connected to the upper surface of the base, a limit plate provided inside the housing, a slider slidably connected inside the limit plate, a straightening component provided inside the housing, a quick-release component provided inside the housing, a telescopic component provided inside the housing, a bracket provided on one side of the upper surface of the worktable, a wire inlet box fixedly connected to the upper surface of the bracket, a lifting component provided inside the wire inlet box, a wire outlet component provided on the other side of the upper surface of the worktable, and a driving component provided on the other side of the upper surface of the worktable;

[0006] The quick-release assembly includes a housing, the outer wall of which is disposed inside the slider, a pressing rod is disposed inside the housing, a spring is sleeved on the outer wall of the pressing rod, and a ball bearing is disposed inside the housing.

[0007] Furthermore, the lifting assembly includes a movable rod, the outer wall of which is slidably connected to the inside of the cable inlet box. A spring is sleeved on the outer wall of the movable rod. A limit box is fixedly connected to the lower surface of the movable rod. A connecting rod is rotatably connected inside the movable rod. An eccentric wheel is rotatably connected to the outer wall of the connecting rod. A hand lever is fixedly connected to the outer wall of the eccentric wheel.

[0008] Furthermore, an upper roller is rotatably connected inside the limiting box, and a lower roller is rotatably connected inside the wire inlet box.

[0009] Furthermore, a baffle is provided on the upper surface of the housing, and a roller rotates inside the slider, with a ring-shaped force sensor fixedly connected to one end of the roller.

[0010] Furthermore, the telescopic assembly includes an electric telescopic rod, one end of which is fixedly connected to one side of an inner wall of the housing, and a movable block is fixedly connected to the output end of the electric telescopic rod. The movable block has a hole inside, and a connecting block is provided on the upper surface of the movable block. The connecting block has a through hole inside.

[0011] Furthermore, the output assembly includes a housing second, inside which a gear is provided, and a roller second is fixedly connected to one side of the gear.

[0012] Furthermore, the drive assembly includes a motor, which is disposed on one side of the housing. The output end of the motor passes through the housing and is fixedly connected to the inside of the gear. A base is fixedly connected to the lower surface of the motor, and the lower surface of the base is fixedly connected to the upper surface of the workbench.

[0013] Furthermore, a cable pass box is fixedly connected to one side of the housing, and two rollers are arranged symmetrically inside the cable pass box. A cable exit box is fixedly connected to the other side of the housing, and two rollers are arranged symmetrically inside the cable exit box.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the quick-release component adopts a snap-on design, which allows for quick disassembly or replacement of the rollers by pressing, greatly shortening maintenance time and reducing downtime losses. The ring force sensor monitors the roller pressure in real time, and the CNC table controls the telescopic component accordingly to dynamically adjust the roller spacing and pressure, adapting to tin-plated copper wires of different diameters. This avoids deformation of thin wires due to excessive pressure and insufficient straightening of thick wires. The limit plate and slider work together to reduce lateral displacement of the copper wire, protect the tin plating layer, and ensure the straightness and conductivity of the copper wire after straightening.

[0016] 2. In this utility model, the lifting component drives the eccentric wheel to move the rod via a hand lever, thereby achieving stepless adjustment of the wire entry height. The operator only needs to rotate the hand lever to adapt to different wire diameters or process requirements, which significantly simplifies the manual intervention process. The elastic buffer provided by the second spring can automatically compensate for sudden changes in copper wire tension, prevent wire jamming or plating scratches, and ensure the stability of continuous production. This design not only improves the ease of operation but also reduces the risk of equipment failure due to improper operation, further meeting the requirements of automated production lines for high efficiency and low maintenance costs.

[0026] The quick-release assembly includes a limiting plate 8 with multiple evenly arranged slots. The outer wall of the limiting plate 8 is slidably connected to the inside of the housing 4, allowing the limiting plate 8 to be removed. A slider 9 is installed inside the limiting plate 8, allowing it to slide longitudinally within the limiting plate 8.

A spring 15 is sleeved on the outer wall of the pressing rod 13, and a ball bearing 16 is installed inside the outer shell 14. Pressing the pressing rod 13 compresses the spring 15, causing the ball bearing 16 to retract, allowing the quick-release assembly to be removed and the slider 9 and related components to be unloaded. The straightening assembly includes rollers 10, which are rotatably connected to the inside of the slider 9. Multiple rollers 10 roll simultaneously to straighten the copper wire. One end of each roller 10 is fixedly connected to... A ring-shaped force sensor 11 is electrically connected to the CNC table 2, and can transmit the measured pressure back to the CNC table 2 for intelligent analysis in real time. A detachable baffle 12 is provided on the upper surface of the housing 4 to prevent the limit plate 8 from falling out. The baffle 12 is detachable.

[0027] Reference Figures 4-5The lifting assembly includes a movable rod 22, which is slidably connected to the outer wall of the wire inlet box 18 and can move up and down. A spring 23 is fitted onto the outer wall of the movable rod 22. A limit box 20 is fixedly connected to the lower surface of the movable rod 22. A connecting rod 24 is rotatably connected inside the movable rod 22. An eccentric wheel 25 is rotatably connected to the outer wall of the connecting rod 24. A handle 26 is fixedly connected to the outer wall of the eccentric wheel 25. Rotating the handle 26 rotates the eccentric wheel 25, pulling up the movable rod 22 and causing the limit box 20 to compress the spring 23. After releasing the handle, the spring 23 returns to its original position, and the limit box moves down back to its original position. An upper roller 21 is rotatably connected inside the limit box 20, and a lower roller 19 is rotatably connected inside the wire inlet box 18. The copper wire passes between the upper roller 21 and the lower roller 19. A housing 27 is fixedly connected to the other side of the upper surface of the worktable 1. The housing 27 has a gear 32 for transmission, and a roller 33 is fixedly connected to one side of the gear 32 as the driving wheel. The drive assembly includes a motor 31, which is located on one side of the housing 27. The output end of the motor 31 passes through the housing 27 and is fixedly connected to the inside of the gear 32. When the motor starts, it drives the gear 32 and the roller 33 to rotate counterclockwise, driving the copper wire to move to one end. A base 30 is fixedly connected to the lower surface of the motor 31, and the lower surface of the base 30 is fixedly connected to the upper surface of the workbench 1. A wire guide box 28 is fixedly connected to one side of the housing 27. The wire guide box 28 has two rollers arranged symmetrically inside to feed the straightened copper wire into the wire output assembly. A wire output box 29 is fixedly connected to the other side of the housing 27. The wire output box 29 has two rollers arranged symmetrically inside to feed the straightened copper wire out of the wire output assembly.

[0028] Working principle: Starting motor 31 turns on the equipment. Under the traction of the straightening device, the tinned copper wire enters the straightening area from the wire inlet box 18. Roller 10 contacts the copper wire and applies straightening force. Ring-shaped force sensor 11 (model GML640) senses the pressure of roller 10 on the copper wire in real time and transmits the pressure data to CNC console 2. CNC console 2, based on preset straightening parameters and the received pressure feedback information, sends commands to the telescopic assembly. The telescopic assembly includes an electric telescopic rod 5, a moving block 6, and a connecting block 7. The electric telescopic rod 5 extends according to the commands. The output end is retracted, pushing the moving block 6 and connecting block 7, which drives the slider 9 and roller 10 to adjust their positions, thereby realizing the dynamic adjustment of the straightening parameters of tin-plated copper wires of different diameters. The copper wire is straightened by roller 10, passes through the wire box 28, is straightened again between rollers 23 and is rolled out, and passes through the wire box 29 to complete the straightening. The quick-release assembly consists of the outer shell 14, the pressing rod 13, the spring 15, and the ball 16. When the roller 10 is worn and needs to be replaced, press the pressing rod 13, the spring 15 is compressed, and the ball 16 is retracted, so that the baffle 12 can be opened to replace the roller 10.

[0029] When straightening tin-plated copper wire is required, the operator rotates the lifting assembly lever 26 according to the wire diameter or process requirements. The lifting assembly includes a moving rod 22, spring 23, limit box 20, connecting rod 24, eccentric wheel 25, and lever 26. The rotation of lever 26 drives the eccentric wheel 25 to rotate. The eccentric wheel 25 is linked to the moving rod 22 through the connecting rod 24, causing the moving rod 22 to slide up and down in the wire inlet box 18 to adjust the wire inlet height. When the wire diameter is thick, rotating lever 26 raises the moving rod 22, increasing the distance between the upper roller 21 and the lower roller 19. When the wire diameter is thin, the moving rod 22 lowers, decreasing the distance between the rollers. During the copper wire conveying process, if the copper wire tension changes suddenly, spring 23 automatically extends and retracts to compensate for the tension change and prevent the wire from getting stuck or the plating from being scratched.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
