Description

Technical Field

[0001] This utility model relates to the field of annealing tin plating machine wiring technology, and in particular to a wiring mechanism for an annealing tin plating machine. Background Technology

[0002] Currently, in the field of copper wire processing, annealing and tin plating are key processes to improve the conductivity, corrosion resistance, and mechanical properties of copper wires. As the core component connecting the annealing process with the tin plating and winding processes, the wire laying mechanism of the annealing and tin plating machine directly determines the processing quality and production efficiency of the copper wire. In practical applications, the mainstream annealing and tin plating machine wire laying mechanisms still have many technical defects and cannot meet the needs of high-quality copper wire processing.

[0003] During the annealing process, rolling oil, quenching agents, and other oil stains remain on the surface of the copper wire, and an oxide layer is easily formed under high temperature conditions. In addition, dust and impurities in the air will adhere to the copper wire during transportation. Existing wire laying mechanisms often only focus on the wire laying function and do not integrate a synchronous cleaning module. These adhering substances directly enter the tin plating process with the copper wire: oil stains will block the contact between liquid tin and the copper wire substrate, resulting in defects such as pinholes and bubbles in the tin layer; the oxide layer will reduce the bonding strength between the tin layer and the copper wire, causing the conductivity and corrosion resistance of the tin-plated copper wire to drop significantly, which cannot meet the high-quality requirements of precision electronic and electrical equipment for copper wire.

[0004] To address this issue, we propose a wire routing mechanism for an annealing tin plating machine. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a wire laying mechanism for an annealing tin plating machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Preferably, the guide cover is funnel-shaped, and multiple tabs are provided on both the inner wall of the guide cover and the outer side of the cleaning cloth, and they correspond to each other.

[0010] Preferably, a material roller is rotatably mounted on one side of the inner wall of the cable box, and a clamping plate is threadedly mounted on one side of the material roller via a screw.

[0011] Preferably, the pressure detection assembly includes a limiting ring slidably mounted on the limiting rod, the limiting ring being fixedly connected to the side wall of the movable box, positioning rings slidably mounted on both sides of the limiting rod, and pressure sensors being fixedly mounted on the side walls of the positioning rings, with the two pressure sensors corresponding to the two sides of the limiting rings respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, through the combination of a cooling box and cooling components, can quickly cool copper wires that are at high temperatures after annealing, preventing problems such as uneven tin plating and performance damage caused by the high-temperature copper wires directly entering subsequent processes, thus ensuring the quality of copper wire processing from the source. The combination of the lead screw and the wire cleaning mechanism not only drives the wire cleaning mechanism to move through the lead screw, guiding the copper wires to be evenly arranged and wound along the axial direction of the barrel, solving the stacking and uneven gap problems that are common in traditional wire winding, and ensuring the regularity of the barrel winding, but also simultaneously cleans oil stains, oxide layers and other adhering substances on the outer surface of the copper wire, preventing impurities from affecting the tin plating effect. The cooperation of the limit rod and the pressure detection component can accurately control the reciprocating stroke of the wire cleaning mechanism, avoiding collision damage caused by the mechanism's overtravel. At the same time, the pressure feedback ensures the stability of the movement process, reducing wire winding failures caused by stroke deviation, and improving the overall reliability of the mechanism operation and the quality of copper wire processing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A wire routing mechanism for an annealing tin plating machine includes: a wire routing box 1, a cooling box 11 installed on one side of the wire routing box 1, both the cooling box 11 and the wire routing box 1 being placed on the ground, and a cooling component installed on the cooling box 11 for cooling high-temperature copper wires;

[0024] A lead screw 2 is rotatably installed inside the internal cavity of the cable box 1. A bearing is fixedly installed on one side of the inner wall of the cable box 1. The inner shaft of the bearing is fixedly connected to one end of the lead screw 2. A first motor is fixedly installed on the outside of the cable box 1. The drive output end of the first motor is connected to the drive shaft, and the other end of the drive shaft passes through the side wall of the cable box 1 and is fixedly connected to the other end of the lead screw 2. A cable cleaning mechanism is adapted to be installed on the lead screw 2, which is used to guide the copper wire to be evenly distributed along the axial direction of the barrel and wrapped around the outer wall of the barrel, and to clean the adhering substances on the outer surface of the copper wire.

[0025] A limit rod 3 is provided at the bottom of the lead screw 2. The two ends of the limit rod 3 are fixedly installed on the inner wall of the cable box 1. A pressure detection component is correspondingly assembled on the limit rod 3, which is used for the cable cleaning mechanism to reciprocate along the axial direction of the lead screw 2.

[0026] First, the annealed high-temperature copper wire enters the cooling box 11. The cooling system is activated, and heat exchange occurs between the copper wire and the cooling liquid through immersion or air cooling, rapidly absorbing the heat and reducing the temperature to a suitable range for tin plating. Then, the copper wire enters the wire guide box 1. The drive unit rotates the lead screw 2. Because the wire cleaning mechanism is adapted to the lead screw 2, the rotational motion of the lead screw 2 is converted into linear motion of the wire cleaning mechanism along the axis of the lead screw 2. During this motion, the wire cleaning mechanism guides the copper wire along its own trajectory, evenly arranging it along the axis of the barrel and winding it around the outer wall of the barrel. Simultaneously, it contacts the surface of the copper wire through its own cleaning structure, wiping or scraping away surface adhering substances. At the same time, the wire cleaning mechanism is linked to the pressure detection component on the limit rod 3. When the wire cleaning mechanism moves to the preset positions at both ends of the limit rod 3, it triggers the detection element of the pressure detection component. The detection element feeds a signal back to the control system, which then adjusts the rotation direction of the lead screw 2, causing the wire cleaning mechanism to move in the opposite direction, thus achieving reciprocating wire arrangement.

[0027] Furthermore, the cable cleaning mechanism includes a movable box 21 threadedly mounted on the lead screw 2. The movable box 21 has a screw hole in the middle, which is threadedly connected to the lead screw 2. A guide cover 22 is fixedly mounted on the side wall of the movable box 21. A cleaning cloth 23 is provided inside the guide cover 22, and the end of the cleaning cloth 23, which is rolled in a ring, passes through the port of the guide cover 22.

[0028] When the lead screw 2 rotates under the drive of the drive device, the movable box 21, which is adapted to the thread of the lead screw 2, is subjected to the helical force of the thread of the lead screw 2 and makes a stable linear motion along the axis of the lead screw 2, driving the entire wire cleaning mechanism to move synchronously. During the conveying process, the copper wire first enters the interior of the guide cover 22. The cavity structure of the guide cover 22 constrains the copper wire and prevents the copper wire from deviating from the moving trajectory. At the same time, the cleaning cloth 23, which is rolled up in a ring inside the guide cover 22, is in close contact with the outer surface of the copper wire. Under the dual action of the continuous conveying of the copper wire and the movement of the guide cover 22 driven by the movable box 21, the cleaning cloth 23 generates relative friction with the surface of the copper wire, and wipes the outer surface of the copper wire in all directions to remove oil stains, oxide layers and other adhering substances.

[0029] Furthermore, the guide cover 22 is funnel-shaped, and multiple tabs 24 are provided on the inner wall of the guide cover 22 and the outer side of the cleaning cloth 23, and they correspond to each other.

[0030] During the copper wire insertion stage, because the guide cover 22 is funnel-shaped with a larger opening at the larger end than at the smaller end, the copper wire can more easily enter the interior of the guide cover 22 from the larger end. It then gradually converges towards the smaller end along the funnel-shaped cavity and finally exits from the smaller end. During this process, the friction between the inner wall of the guide cover 22 and the copper wire is small, reducing the resistance to wire insertion. When installing the cleaning cloth 23, align and press the corresponding tabs 24 on the outer side of the annular cleaning cloth 23 with the tabs 24 on the inner wall of the guide cover 22. The hook side and the rough side of the tabs 24 will quickly adhere together, thus fixing the cleaning cloth 23 to the guide cover 22. When the cleaning cloth 23 needs to be replaced, simply tear the cleaning cloth 23 off the inner wall of the guide cover 22 to separate the tabs 24, and then remove the old cleaning cloth 23. Then, attach the new cleaning cloth 23 in the same way to ensure that the cleaning cloth 23 is always tightly attached to the inner wall of the guide cover 22 without any displacement gaps.

[0031] Furthermore, a material roller 25 is rotatably mounted on one side of the inner wall of the cable box 1, and a second motor is fixedly mounted on the outer side of the cable box 1. The output end of the second motor is connected to the transmission shaft, and the other end of the transmission shaft passes through the side wall of the cable box 1 and is fixedly connected to the central shaft of the material roller 25. A clamping plate 26 is installed on one side of the material roller 25 through a screw thread, and a screw hole is opened in the middle of the other end of the material roller 25. A screw is threaded into the screw hole, and the other end of the screw is fixedly connected to the clamping plate 26.

[0032] The operator first places the copper wire winding cylinder onto the outer surface of the roller 25, ensuring a tight fit between the inner wall of the cylinder and the outer wall of the roller 25. Then, the screw at the other end of the roller 25 is rotated. Because the screw is threadedly connected to the screw hole in the middle of the roller 25, the rotational motion of the screw is converted into linear motion along the axial direction of the roller 25, which in turn pushes the clamping plate 26, which is fixedly connected to the screw, to move towards the cylinder. When the side wall of the clamping plate 26 is in close contact with the end of the cylinder, the screw is stopped from rotating. At this time, the clamping plate 26 and the limiting structure at the other end of the roller 25 form a bidirectional clamping force, firmly fixing the cylinder to the roller 25 and preventing the cylinder from shifting axially or slipping circumferentially during the winding process.

[0033] When the mechanism starts the winding program, the second motor on the outside of the wire box 1 is powered on and the material roller 25 rotates. The material cylinder fixed on its outer surface rotates synchronously with the material roller 25. Using the rotational torque of the material cylinder, the copper wire guided by the wire cleaning mechanism is evenly wound on the outer wall of the material cylinder, realizing the automatic winding of the copper wire.

[0034] Furthermore, the pressure detection assembly includes a limiting ring 31 that is slidably mounted on the limiting rod 3. The limiting ring 31 is fixedly connected to the side wall of the moving box 21. Positioning rings 32 are slidably mounted on both sides of the limiting rod 3. Pressure sensors 33 are fixedly mounted on the side walls of the positioning rings 32. The two pressure sensors 33 correspond to the two sides of the limiting ring 31 respectively.

[0035] When the movable box 21 moves along the lead screw 2, it will drive the limiting ring 31, which is fixedly connected to it, to slide synchronously along the limiting rod 3. The positioning rings 32 on both sides of the limiting rod 3 are fixed in the preset stroke position by bolts 34, and the pressure sensor 33 on the positioning ring 32 is in the detection state. When the limiting ring 31 moves with the movable box 21 to the positioning ring 32 on one side, the limiting ring 31 will contact the sensing end of the pressure sensor 33 on that side and generate pressure. The pressure sensor 33 converts the pressure signal into an electrical signal and transmits it to the control system of the mechanism. After receiving the signal, the control system determines that the cable cleaning mechanism has reached the end of the stroke and then issues a command to control the lead screw 2 drive device to reverse. The lead screw 2 rotates in the opposite direction, driving the movable box 21 and the cable cleaning mechanism to move in the opposite direction. When the limiting ring 31 moves to the pressure sensor 33 on the other side, the above pressure detection and reversal process is repeated to realize the automatic reciprocating movement of the cable cleaning mechanism, and there is no mechanical hard collision throughout the process.

[0036] Furthermore, a screw hole is provided in the middle of the side wall of the positioning ring 32, and a bolt 34 is installed in the screw hole with internal thread. The bolt 34 corresponds to the outer wall of the limiting rod 3.

[0037] When the reciprocating stroke of the cable cleaning mechanism needs to be adjusted, the operator first rotates the bolt 34 on the side wall of the positioning ring 32 counterclockwise. Because the bolt 34 is threadedly connected to the screw hole of the positioning ring 32, the bolt 34 gradually disengages from the tight contact with the outer wall of the limiting rod 3 as it rotates, and the fixed state between the positioning ring 32 and the limiting rod 3 is released. Then, the positioning ring 32 is pushed or pulled along the axial direction of the limiting rod 3 to move it to a new position that matches the length of the barrel. After reaching the target position, the bolt 34 is rotated clockwise so that the end of the bolt 34 gradually presses against the outer wall of the limiting rod 3. Through the static friction between the bolt 34 and the limiting rod 3, the positioning ring 32 is fixed on the limiting rod 3. After the positions of the positioning rings 32 on both sides are adjusted, the reciprocating stroke range of the cable cleaning mechanism is limited to between the two positioning rings 32, realizing flexible adjustment of the stroke.

[0038] Furthermore, the cooling assembly includes several first guide rollers 12 rotatably mounted inside the cooling box 11. Several bearings are fixedly mounted on the inner wall of the cooling box 11. The inner shaft of each bearing is fixedly connected to the central shaft of the corresponding first guide roller 12. Supports 13 are fixedly mounted at both ends of the side wall of the cooling box 11. Second shafts are rotatably mounted at both ends of the front side of the support 13. Bearings are fixedly mounted in the middle of both sides of the support 13. The inner shaft of each bearing is fixedly connected to the central shaft of the corresponding second guide roller 14. Fans 15 are mounted on the back side of the two supports 13. Screw holes are opened on the side wall of the fan 15 and the support 13. Bolts 34 are threaded into the corresponding two screw holes. Coolant is provided inside the cooling box 11.

[0039] First, coolant is injected into the cooling tank 11, and several first guide rollers 12 are immersed in the coolant. After the copper wire enters the cooling tank 11, it passes around the multiple first guide rollers 12 in sequence, forming a meandering path. The copper wire is in full contact with the coolant and transfers its own heat to the coolant through heat conduction, achieving initial cooling. Then, the cooled copper wire passes out of the cooling tank 11 and enters the bracket 13 area. The two second rotating shafts on the front side of the bracket 13 support and guide the copper wire. The copper wire passes around the two second rotating shafts, changes its conveying direction, and smoothly enters the subsequent wiring box 1, avoiding bending caused by direct turning of the copper wire. At the same time, the fan 15 on the back side of the bracket 13 is started, blowing airflow onto the surface of the copper wire. On the one hand, it accelerates the evaporation of the residual coolant on the surface of the copper wire and prevents the liquid from being carried into the wiring mechanism. On the other hand, the airflow conducts secondary heat exchange with the copper wire, further reducing the temperature of the copper wire and ensuring that the temperature of the copper wire is stable within the preset range.

[0040] Furthermore, the copper wires are continuously extended and sequentially pass through the first guide roller 12 and the second guide roller 14, and the copper wires are arranged in a spring-shaped path distribution relative to the first guide roller 12 and the second guide roller 14.

[0041] Inside the cooling box 11, copper wires pass sequentially through each of the first guide rollers 12 along a preset trajectory. The installation height or position of adjacent first guide rollers 12 differs, causing the copper wires to form a spring-shaped path during winding. Simultaneously, after exiting the cooling box 11, the copper wires continue to wind around the two second rotating shafts on the bracket 13, further extending the spring-shaped trajectory. This path design significantly increases the contact length between the copper wires and the coolant within the limited space of the cooling box 11. Compared to a straight path, the contact area between the copper wires and the coolant is several times larger under the spring-shaped path, and the contact time is correspondingly extended, resulting in more thorough heat exchange. In addition, each first guide roller 12 and second rotating shaft provides a certain tension and limiting effect on the copper wires. The coordinated constraint of multiple guide rollers ensures that the copper wires maintain appropriate tension throughout the conveying process, preventing slackness and entanglement caused by their own weight or fluctuations in conveying speed, thus ensuring a stable conveying trajectory.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
