Description

Technical Field

[0001] This utility model relates to the field of copper wire processing technology, and more specifically, to a copper wire surface cleaning structure. Background Technology

[0002] The main purpose of cleaning the surface of copper wire is to remove oxide layers, oil stains or other contaminants to improve its conductivity, solderability or appearance.

[0003] Currently, when cleaning the surface of copper wire, very fine sandpaper or metal shavings are generally used to gently polish the surface along the length of the wire. However, this can easily lead to excessive abrasion, causing the wire to become thinner or break (especially for thin copper wires). Alternatively, a chemical solution can be used to soak and wipe the copper wire, dissolving the copper oxide and cuprous oxide on the surface and improving cleanliness. However, all chemical solutions require thorough rinsing; otherwise, residues will continue to corrode the copper or affect subsequent use. Another option is to use an ultrasonic cleaning chamber to automatically clean the surface of the copper wire, quickly removing contaminants or oil.

[0004] The Chinese utility model patent, titled "A Copper Wire Surface Cleaning Device" and with publication number CN221848042U, includes a cleaning mechanism comprising a guiding component, a redirecting component, and an ultrasonic cleaning box. The redirecting component is vertically connected to the inner wall of the ultrasonic cleaning box. Through various sliding redirecting rollers, the copper wire is redirected and drawn into the cleaning box, where the ultrasonic cleaning box cleans the surface of the copper wire.

[0005] Although this utility model uses an ultrasonic cleaning box to quickly clean the surface of copper wires, when encountering a copper wire production line that needs to ensure processing results, the copper wire cleaning structure of the production line needs to ensure both cleaning efficiency and cleanliness of the copper wires.

The plurality of branching plates are evenly arranged on the slide rod, and there are gaps between adjacent branching plates.

[0017] Preferably, the gaps between the copper wires and the dividing plate are one-to-one.

[0018] Preferably, the brush structure further includes two upright plates, and the spacing adjustment structure includes sliding holes and a motor.

[0019] Preferably, the two upright plates are fixedly erected on the frame and located on both sides of the cleaning chamber.

[0020] Preferably, a motor is fixed on the upright plate, and a screw is coaxially fixed on the motor's drive shaft. The screw passes vertically through the surfaces of the two sliding plates, and the screw thread matches the through hole of the sliding plate.

[0021] Preferably, the thread on the screw is a bidirectional thread, with the thread directions of the bidirectional thread being opposite and symmetrically arranged at both ends of the screw, and the threads in the two directions respectively matching two sliding plates.

[0022] Preferably, the frame is further provided with roller components, which include flat rollers and pressure rollers.

[0023] Preferably, the two flat rollers are symmetrically arranged at both ends of the conveying direction of the brush structure, the roller surfaces of the two flat rollers are located on the same horizontal plane, and the distance between the copper wires on the roller surfaces of the two flat rollers and the upper and lower brush surfaces is consistent.

[0024] Preferably, the two lower pressure roller shafts are rotatably disposed within the cleaning chamber.

[0025] Preferably, the elastic buffer structure includes a spring.

[0026] Preferably, one end of the spring is fixedly connected to the mounting plate, and the other end is fixedly connected to the surface of the pressure plate.

[0031] The technical solution of this application has at least the following advantages and beneficial effects:

[0032] In this invention, a brush structure is set at the feed inlet of the ultrasonic cleaning chamber to pre-treat the copper wire entering the cleaning chamber. The brush is used to brush away the dirt attached to its surface, reducing its adhesion. This makes it easier for the dirt to be quickly removed during a short ultrasonic treatment after the copper wire enters the cleaning chamber, thus improving the cleaning efficiency of the copper wire.

[0033] In this utility model, by setting a wire splitting structure, a wire spacing sensor and a spacing adjustment structure on the frame, several copper wires are input into the cleaning chamber and their wire diameters are measured, thereby adjusting the spacing between the brushes and automatically matching the wire diameter type of the copper wire, thereby improving the cleaning efficiency of copper wires when the wire diameter type changes.

[0034] In this invention, by incorporating an elastic buffer structure and a pressure sensor into the brush bristle structure, when the conveyed copper wire has a bent section, the brush can maintain appropriate elastic bristle pressure with several conveyed copper wires through the elastic buffer structure. The pressure sensor provides feedback on the elastic pressure, allowing the elastic buffer structure to adjust the elastic pressure in real time via a drive component. This prevents excessive elastic pressure, which could damage the copper wire surface, and also prevents insufficient elastic pressure, which would prevent the brush from effectively cleaning the bent copper wire surface.

[0045] Example

[0046] Please refer to Figures 1-7 This utility model provides a copper wire surface cleaning structure, including a frame 1 for supporting various structures. A cleaning chamber 2 is installed in the middle of the frame 1. When the copper wire passes through the chamber, it will be cleaned of dirt by the cleaning liquid. The inlet and outlet of the cleaning chamber 2 are also provided with a wire separating structure 3 to separate several copper wires and prevent them from tangling together during cleaning. The frame 1 is also provided with a roller 4. The two ends of the copper wire are respectively transported and displaced by an external wire conveying device. During the displacement, the roller 4 holds and tightens the copper wire to keep it straight during the conveying process, and guides it into the cleaning chamber 2 and the outlet through the roller 4 to maintain the conveying operation.

[0047] The branch structure 3 includes a bracket 301, a slide bar 302, and a branch plate 303.

[0048] Please refer to Figure 2 In this embodiment, the bracket 301 is fixed on the frame 1, and a slide rod 302 is horizontally arranged on the bracket 301. Several wire splitting plates 303 are fixedly sleeved on the slide rod 302. The wire splitting plates 303 are evenly arranged on the slide rod 302, and there are gaps between adjacent wire splitting plates 303. When splitting several copper wires, each copper wire passes through the gap between a wire splitting plate 303 individually to realize wire splitting and conveying. When the split copper wires are conveyed, they slide on the smooth surface of the slide rod 302 to reduce the degree of wear on the surface of the copper wires.

[0049] The cleaning chamber 2 is configured as an ultrasonic cleaning chamber 2, which contains cleaning fluid. An ultrasonic generator is installed at the bottom of the chamber. When the copper wire is cleaned, the copper wire passes through the cleaning fluid in the chamber, and the ultrasonic generator is activated, so that the dirt on the surface of the copper wire in the chamber is ultrasonically cleaned away.

[0050] However, in actual use, the entire copper wire cleaning device is located on the copper wire production line (or processing line). When there is a relatively tight dirt on the surface of the copper wire, it needs to be ultrasonically treated in the cleaning chamber 2 for a long time to clean it thoroughly. However, the process time of the entire copper wire production line is tight, and the ultrasonic treatment time will affect the production efficiency of the entire production line. However, in order to ensure efficiency, it is difficult to clean the surface of the copper wire thoroughly by shortening the ultrasonic time.

[0051] Therefore, a brush structure 6 for pre-cleaning copper wires is also provided on the frame 1. It is located at the feed inlet of the cleaning chamber 2 and brushes the dirt on the surface of the copper wires entering the cleaning chamber 2 in advance, so that its adhesion is reduced and it is easier to be cleaned away quickly by ultrasonic waves.

[0052] Please refer to Figure 4 and Figure 5 In this embodiment, the brush structure 6 includes a vertical plate 601, a spacing adjustment structure, a mounting plate 604, brush bristles 605, and a sliding column 606.

[0053] Specifically, two upright plates 601 are fixedly erected on the frame 1, located on both sides of the cleaning chamber 2. Two mounting plates 604 are arranged vertically between the two upright plates 601. Each of the opposite surfaces of the two mounting plates 604 is covered with a layer of bristles 605. The two mounting plates 604 form an upper and lower clamping structure. The copper wires after being split by the wire splitting structure 3 pass through the bristles 605 between the two mounting plates 604. The upper and lower layers of bristles 605 brush the dirt on the entire surface of the copper wire, reducing the adhesion of the dirt.

[0054] Furthermore, due to the production requirements of copper wire, copper wires come in different diameter types. Therefore, when cleaning the surface of copper wire, it is necessary to implement surface cleaning functions for copper wires of different diameter types. When the upper and lower clamping bristles 605 are installed outside the cleaning chamber 2, the spacing between the upper and lower clamps needs to be considered according to the wire diameter type in order to clean the dirt from the surface of copper wires of different diameter types.

[0055] Therefore, the spacing adjustment structure includes a sliding hole 602, a sliding plate 603, a screw 607, and a motor 608.

[0056] Specifically, the upright plate 601 has two through-holes 602, each containing a corresponding sliding plate 603. The two sliding plates 603 slide vertically, and their opposing surfaces are connected to mounting plates 604, allowing the mounting plates 604 and their brush bristles 605 to move vertically with the sliding plates 603, changing their vertical spacing. A motor 608 is fixed to the upright plate 601, and a screw 607 is coaxially fixed to the motor 608's drive shaft. The screw 607 vertically passes through the surfaces of the two sliding plates 603, and its threads match the through-holes in the sliding plates 603. When the motor 608 rotates the screw 607, the threads drive the two sliding plates 603 to move vertically, providing them with displacement driving force.

[0057] It is worth noting that the thread on the screw 607 is a bidirectional thread, with the thread directions being opposite and symmetrically arranged at both ends of the screw 607. The two sliding plates 603 are matched with different threads, so that when the screw 607 rotates, the two sliding plates 603 on the screw 607 will move towards each other or relative to each other, thereby realizing the adjustment of the upper and lower clamping distance of the two mounting plates 604 and the brushes on them.

[0058] Furthermore, if the motor 608 needs to be manually adjusted every time the copper wire diameter is changed, thereby adjusting the clamping distance of the brush, manual adjustment will inevitably reduce production efficiency in actual production. Therefore, it is necessary to automatically adjust the clamping distance of the upper and lower brushes according to the change of copper wire diameter.

[0059] Therefore, please refer to Figure 2 In this embodiment, a wire spacing sensor 5 is fixedly installed on the bracket 301 of the wire splitting structure 3. The wire spacing sensor 5 is connected to the rotation control circuit of the motor 608 through a signal line. The wire spacing sensor 5 consists of two wire spacing laser sensors arranged vertically and vertically. The two wire spacing laser sensors are located at the upper and lower ends of the slide rod 302 and correspond to the gap position of one of the wire splitting plates 303. When different wire diameters slide through the gap of the wire splitting plate 303, they will be sensed by the laser beams emitted by the two wire spacing laser sensors, and their wire diameter width will be detected. This will send electrical signals of different intensities to the rotation control circuit of the motor 608, thereby controlling the motor 608 to rotate different numbers of revolutions, and realizing the automatic adjustment of the clamping distance of the upper and lower brushes according to the size of the copper wire diameter.

[0060] It is worth noting that when the copper wire passes through the brush surfaces held by the upper and lower clamps, the brushes brush away the dirt on the surface. However, in order to ensure that the upper and lower horizontal brush surfaces can adhere to the surface of the copper wire and ensure the brushing effect, the copper wire passing through the upper and lower horizontal brushes also needs to maintain a horizontal movement. If the copper wire passes through at an angle, it is easy for the upper and lower surfaces of the copper wire to not adhere to the corresponding brush surfaces, affecting the brushing effect. It is also easy for the copper wire to tilt and interfere with the support plates held by the upper and lower clamps due to displacement.

[0061] Therefore, please refer to Figure 3 In this embodiment, the roller component 4 includes a flat roller 401 and a pressure roller 402.

[0062] Specifically, the flat roller 401 consists of a support plate and a roller rotatably mounted thereon. Two flat rollers 401 are symmetrically arranged at both ends of the conveying direction of the brush structure 6. The roller surfaces of the two flat rollers 401 are located on the same horizontal plane, so that when the copper wire is tensioned and conveyed by the rollers of the flat rollers 401, the copper wire is conveyed horizontally. In addition, the roller surfaces of the two flat rollers 401 also correspond to the midpoint of the clamping point between the upper and lower brushes, so that the copper wire is conveyed horizontally to the clamping midpoint, and the distance between the copper wire and the upper and lower brush surfaces is consistent, maintaining the cleaning effect of the upper and lower brushes.

[0063] In addition, the two lower pressure roller shafts 402 are rotatably arranged inside the cleaning chamber 2, so that after the copper wire passes through the flat roller shaft 401, it is pressed into the lower cavity space by the lower pressure roller shaft 402, is immersed in the cleaning liquid, and is ultrasonically cleaned.

[0064] Furthermore, the copper wire production process includes a straightening process to straighten the copper wire and prevent it from bending. However, in the actual copper wire production process (especially in the recycling and reuse of waste copper wire), some parts of the copper wire are highly bent, and it is not easy to straighten them completely by manual or mechanical straightening. Moreover, the long-term guiding and conveying of the copper wire on the production line will cause some parts to bend again, making it difficult to straighten by the roller component 4 (if the roller tension is too large, it is easy to cause the copper wire to break, so the tension is not large enough to straighten the copper wire). Therefore, when the copper wire passes through the brush surface held by the upper and lower clamps, the bent parts are difficult to be completely covered by the brush surface to brush away dirt, thus affecting the cleaning effect and easily colliding with the mounting plate 604 outside the brush, resulting in damage or even breakage of the copper wire.

[0065] Therefore, an elastic buffer structure 7 and a pressure sensor 8 are also provided on the bristle structure 6. The elastic buffer structure 7 provides elastic buffer for the mounting plate 604 clamped above and below, so that when the bent part of the copper wire collides with the brush surface and the surface of the mounting plate 604, it provides elastic buffer for the mounting plate 604, thereby ensuring that the brush surface always contacts the copper wire surface with appropriate elastic pressure, reducing the problem of easy interference and inadequate cleaning when the bristle structure 6 brushes the bent part of the copper wire.

[0066] The pressure sensor 8 contacts the elastic end of the elastic buffer structure 7 to sense the magnitude of the elastic pressure. The elastic buffer structure 7 also contains a driving element connected to the elastic end. The pressure sensor 8 is connected to the control terminal of the driving element via a circuit. When the elastic pressure is outside the pressure threshold, the pressure sensor 8 sends a signal to the control terminal, causing the driving element to drive the elastic end to undergo elastic displacement. This changes the elastic force of the elastic buffer structure 7, thereby adjusting the magnitude of the elastic pressure between the brush surface and the copper wire surface (the greater the elastic pressure, the stronger the contact between the brush bristles 605 and the copper wire surface, and the stronger the brushing effect, but it is also easier for the copper wire surface to be worn by the brush). This ensures that the normal elastic pressure between the brush surface and the copper wire surface is always maintained, thus maintaining the cleaning effect of the brush on the copper wire and reducing the degree of wear on the copper wire.

[0067] It is worth noting that because several copper wires pass through the brush surface held by the upper and lower parts at the same time, the reaction force generated by the contact of the brush surface after contact with several copper wires will pass through the brush (the contact area is relatively large) and be transmitted to the support plate and the elastic buffer structure 7.

[0068] Please refer to the following: Figures 4-6 In this embodiment, the elastic buffer structure 7 includes a spring 701, a sliding plate 603, a push plate 703, an electric cylinder 704, and a guide post 705.

[0069] In order to achieve elastic displacement of the support plate without affecting the displacement adjustment of the support plate by the spacing adjustment structure, a sliding column 606 is fixedly connected to the plate surface of the support plate near the slide plate 603. The sliding column 606 passes vertically through the plate surface of the slide plate 603, and a stop block is fixed at the end of the sliding column 606 to prevent the sliding column 606 from slipping off the slide plate 603.

[0070] Specifically, a spring 701 and a pressure plate 702 are fitted onto the sliding column 606. One end of the spring 701 is fixedly connected to the mounting plate 604, and the other end is fixedly connected to the surface of the pressure plate 702. The surface of the pressure plate 702 abuts against the surface of the push plate 703. The surface of the push plate 703 is fixedly connected to the drive shaft of the electric cylinder 704. The electric cylinder 704 is fixed on the sliding plate 603. When the electric cylinder 704 works, it pushes the push plate 703 to move vertically, thereby squeezing the spring 701 and changing the extension and contraction of the spring 701. This applies different elastic forces to the mounting plate 604 at one end of the spring 701, thereby applying different elastic pressures when the brush surface contacts the copper wire surface, thus performing brushing.

[0071] Among them, guide posts 705 are symmetrically fixed on the push plate 703. The guide posts 705 are vertically inserted through the slide plate 603 to provide guidance for the vertical displacement of the push plate 703.

[0072] In addition, the pressure sensor 8 is fixed on the push plate 703, and the sensing end of the pressure sensor 8 passes through the push plate 703 and abuts against the surface of the pressure plate 702. It senses the change in the elastic force of the spring 701 connected to the pressure plate 702. The pressure sensor 8 is also connected to the displacement control circuit of the electric cylinder 704 through the wire. By changing the different elastic force transmitted by the spring 701, the displacement of the electric cylinder 704 is changed accordingly, thereby automatically adjusting the elastic displacement of the spring 701 so that the mounting plate 604 is subjected to stable elastic pressure.

[0073] The elastic pressure adjustment process is as follows:

[0074] During the cleaning process of the copper wire surface, the copper wire passes through the brush surface held by the upper and lower clamps. At this time, the spring 701 applies elastic force to the mounting plate 604, and the stop block of the sliding column 606 abuts against the sliding plate 603. The distance between the mounting plate 604 and the sliding plate 603 is constant, so that the mounting plate 604 and the sliding plate 603 can be adjusted together by the distance displacement.

[0075] At this time, when the copper wire is taut, the reaction force generated by the copper wire and the brush surface is applied to the spring 701. When the elastic force acts on the pressure sensor 8, the elastic force is within the pressure threshold range of the pressure sensor 8. The electric cylinder 704 does not work. The mounting plate 604 and the brush apply appropriate elastic pressure to the surface of the copper wire through the spring 701, thereby maintaining appropriate brush pressure for brushing.

[0076] At this time, when the copper wire is bent, the interaction between the copper wire and the brush surface causes the elastic force of the spring 701 to increase or decrease (the copper wire may bend upward or downward). The elastic force will be outside the pressure threshold range of the pressure sensor 8, and the electric cylinder 704 will start to work. It will make a corresponding displacement length according to the magnitude of the pressure signal (if the elastic force is too small, the electric cylinder 704 will move downward to increase the elastic force of the spring 701; if the elastic force is too large, the electric cylinder 704 will move upward to decrease the elastic force of the spring 701). This allows the mounting plate 604 and the brush to apply appropriate elastic pressure to the surface of the copper wire through the spring 701 after the elastic force changes, thereby maintaining appropriate brush pressure for brushing.

[0077] It is worth noting that in the brush structure 6, the mounting plate 604, sliding column 606, and sliding plate 603 are all equipped with springs 701, pressure sensors 8, and electric cylinders 704, etc., so that when the upper and lower clamped brush surfaces come into contact with the bent part of the copper wire, the brush surface at one end reduces the elastic pressure according to the protrusion of the bent part of the copper wire, while the brush surface at the other end increases the elastic pressure according to the concavity of the bent part of the copper wire (when the bent part of the copper wire bends and protrudes to one side, the other side will be concave due to bending). In this way, the upper and lower brush surfaces are respectively adapted to the bent part of the copper wire to brush away dirt.

[0078] It is worth noting that a branching structure 3, a bristle structure 6, an elastic buffer structure 7, and a pressure sensor 8 are also correspondingly installed at the discharge port of the cleaning chamber 2. The cleaning process of the entire copper wire surface cleaning structure is as follows:

[0079] Several copper wires are separated into two groups at the feed inlet of the cleaning chamber 2 by the splitting structure 3. Then, they are conveyed in parallel to the brush surfaces held by the upper and lower rollers 401 to brush away dirt and reduce its adhesion. Then, they are guided into the cleaning chamber 2 by the lower rollers 402 for ultrasonic cleaning, which quickly removes the attached dirt and leaves it in the chamber. The copper wires are then conveyed to the discharge outlet of the cleaning chamber 2 by the flat rollers 401 and conveyed in parallel to the upper and lower brush surfaces there to brush away the dirt that adhered to the copper wires when they exit the liquid. Finally, they are output to other external devices through the splitting structure 3.

[0080] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description.
