Description

Technical Field

[0001] This invention relates to the field of bare copper wire processing equipment, specifically to a bare copper wire outer surface cleaning device. Background Technology

[0002] As a core basic material in the electronics and power fields, the surface cleanliness of bare copper wire directly determines the quality of subsequent processing and the reliability of use. The surface oxide layer will increase the contact resistance, cause conductive loss and overheating of the joint, and hinder the welding bond. Oil, dust and other impurities will affect the stability of subsequent processes such as insulation coating and plating, and shorten the service life of bare copper wire and end products.

[0003] Currently, existing bare copper wire surface cleaning equipment is mainly divided into three categories: First, mechanical grinding, which cleans the surface of bare copper wire by friction with components such as grinding wheels and grinding cotton. However, it suffers from problems such as uncontrollable grinding force, easy damage to the copper wire substrate, rapid wear of grinding parts, frequent replacement, and inability to precisely clean severely oxidized areas, resulting in resource waste and low cleaning efficiency. Second, chemical cleaning, which dissolves oxide layers and impurities with corrosive solutions. Although it can achieve comprehensive cleaning, it suffers from environmental pollution due to wastewater discharge, high consumption of chemical reagents, high cost, and the potential for residual reagents to further corrode the surface of bare copper wire. Third, high-pressure airflow purging, which can only clean surface dust and cannot remove stubborn oxide layers and attached oil stains. Its cleaning effect is limited and cannot meet the needs of high-precision processing.

[0004] In addition, existing cleaning equipment generally suffers from poor compatibility, failing to be compatible with bare copper wires of different diameters and oxidation levels. Specialized accessories are required to clean copper wires of various specifications, making the operation cumbersome and lacking in versatility. At the same time, most equipment lacks real-time detection and feedback adjustment mechanisms, failing to dynamically adjust cleaning parameters based on the distribution of impurities on the copper wire surface, resulting in over-cleaning or incomplete cleaning, further affecting the processing quality of bare copper wires.

[0005] In summary, existing bare copper wire surface cleaning equipment suffers from technical drawbacks such as poor cleaning effect, weak versatility, high energy consumption, insufficient environmental protection, and easy damage to the copper wire substrate. There is an urgent need for a bare copper wire surface cleaning equipment that can solve the above problems and achieve efficient, accurate, environmentally friendly, and universal cleaning. Summary of the Invention

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention provides, for example Figures 1-9 The bare copper wire outer surface cleaning equipment shown includes a mounting frame 1. A wire feeding structure 2 for placing copper wire rolls is provided on one side of the top of the mounting frame 1. A pre-processing module and a post-processing module are sequentially provided on the top of the mounting frame 1 along the extension direction of the copper wire. A drive structure 3 for pulling the copper wire is provided on the other side of the top of the mounting frame 1.

[0035] Both the pre-processing module and the post-processing module include a wiping unit 4, a polishing unit 5 and a high-pressure spraying unit 6. The pre-processing module also includes a heating unit 7 that softens the stains on the surface of the copper wire. The wiping unit 4, the polishing unit 5 and the high-pressure spraying unit 6 wipe the stains on the surface of the copper wire, polish the surface of the copper wire and remove the residual particles and impurities on the surface of the copper wire in sequence.

[0036] Both the pre-processing module and the post-processing module are equipped with detection units 8 for detecting the surface treatment quality of copper wires.

[0037] Mounting frame 1 serves as the overall support structure for the equipment and is made of stainless steel. It has adjustable support legs at the bottom to adjust the level of the equipment and prevent the bare copper wire from shifting due to tilting, thus avoiding misalignment during cleaning. Mounting frame 1 is equipped with a protective shell (not shown in the figure) with an inspection door for easy observation of the equipment's operating status and daily maintenance. It also prevents copper powder and cleaning fluid from splashing during cleaning, ensuring the safety of operators.

[0038] Among them, such as Figure 8 As shown:

[0039] The wire feeding structure 2 is located at one end of the top of the mounting frame 1 to achieve uniform and stable feeding of bare copper wire. It includes a first support frame 21, a feeding roller 22, and a first motor 23. The first support frame 21 is fixedly installed on the top of the mounting frame 1. The feeding roller 22 is rotatably installed inside the first support frame 21, and the first motor 23 is fixedly installed on the outside of the first support frame 21. The output shaft of the first motor 23 is fixedly connected to one end of the feeding roller 22. The copper wire is wound around the outside of the feeding roller 22 (a set of first support frames 21 and mounting frame 1 are detachably connected by bolts, facilitating the installation of copper wire windings on the outside of the feeding roller 22). The outside of the feeding roller 22 is provided with anti-slip textures to prevent the bare copper wire from slipping. Slippage during copper wire transport is prevented to avoid scratches and uneven cleaning of the copper wire surface. The drive structure 3 is located at the other end of the mounting frame 1 to transport the copper wire. It includes a second support frame 31, drive wheels 32 and a second motor 33. The second support frame 31 is fixed to the top of the mounting frame 1, and two sets of drive wheels 32 are rotatably installed inside the second support frame 31. At the same time, the two sets of drive wheels 32 are in contact with the outside of the copper wire. The second motor 33 is installed on the outside of the second support frame 31 and its output end is fixedly connected to the end of one set of drive wheels 32. The second motor 33 serves as the drive source to transport the copper wire, realizing uninterrupted extraction of the copper wire from the copper wire roll for surface treatment.

[0040] Preferred, such as Figure 3 As shown:

[0041] The heating unit 7 includes a third mounting base 71 fixed on the top of the mounting bracket 1. The top of the third mounting base 71 is fixed with a heat insulation cylinder 72 sleeved on the outside of the copper wire. An electromagnetic heating tube 73 is embedded inside the heat insulation cylinder 72. The electromagnetic induction heating method can quickly heat the surface of the bare copper wire to 60-80℃, soften the surface oil and loosen the oxide layer, making it easier for subsequent cleaning.

[0042] Furthermore, such as Figure 4 As shown:

[0043] The wiping unit 4 includes two sets of wiping rings 41 with openings, sleeved on the outside of the copper wire. Flexible wear-resistant fiber brushes 42 are fixedly connected to both ends inside the wiping rings 41. The bristles of the flexible wear-resistant fiber brushes 42 abut against the surface of the copper wire. An edge 43 extends outward from the outer side of the opening of the wiping ring 41. A moving groove is formed at the center of the edge 43, and a nut 44 is slidably disposed within the moving groove. A bidirectional threaded rod 45 is threaded internally connected to the nut 44. Rotation of the bidirectional threaded rod 45 adjusts the distance between the two sets of nuts 44, thereby adjusting the opening of the wiping rings 41 to adapt the flexible wear-resistant fiber brushes 42 to copper wires of different thicknesses. A first mounting base 46 is rotatably connected to the bottom of the bidirectional threaded rod 45 via a bearing. 6 is fixed to the top of the mounting bracket 1. The upper end of the bidirectional threaded rod 45 is movably provided with a movable rod for easy rotation. The bottom of the lower edge 43 is fixed with a limiting rod 47. The top of the first mounting base 46 is provided with a limiting groove 48 for use with the limiting rod 47. By inserting the limiting rod 47 into the limiting groove 48, the stability of the wiping ring 41 can be maintained, preventing the wiping ring 41 from shaking and causing impact to the copper wire, resulting in scratches on the surface of the copper wire. The flexible wear-resistant fiber brush 42 can initially absorb the softened oil and dust, reducing the pressure of subsequent cleaning. The bottom of the wiping ring 41 is connected to the air guide pipe 14. The air guide pipe 14 extends outward and is connected to the negative pressure device, forming a negative pressure in the wiping ring 41 to discharge the cleaned stains and prevent them from accumulating inside the wiping ring 41.

[0044] Preferred, such as Figure 5-6 As shown:

[0045] The polishing unit 5 includes a sleeve 51 fitted around the outside of the copper wire. A second mounting base 52 is rotatably connected to the outside of the sleeve 51 via a bearing. The second mounting base 52 is fixed to the top of the mounting frame 1. Countersunk holes are formed around the outside of the sleeve 51, and limit bolts 53 are movably installed in the countersunk holes. One end of the limit bolt 53 passes through the inside of the sleeve 51 and is threadedly connected to a polishing block 54. An arc-shaped polishing surface that fits against the surface of the copper wire is provided on the opposite side of the polishing block 54. A fixing rod 55 is fixed to the outside of the polishing block 54, and the other end of the fixing rod 55 movably passes through the inside of the sleeve 51. A support spring 56 is fitted on the outside of the fixing rod 55. The two ends of the support spring 56 respectively abut against the polishing block 54 and the sleeve 51. A third motor 57 is mounted on the top of the mounting frame 1. A drive synchronous pulley 58 is fixed to the output shaft of the third motor 57. A driven synchronous pulley 59 is fixed to one end of the sleeve 51. The pulley 58 and the driven synchronous pulley 59 are connected by a synchronous belt drive. The third motor 57 achieves 360° alternating forward and reverse rotation, which can prevent the wires inside the sleeve 51 from getting tangled. An adaptive adjustment component is also set inside, including a displacement sensor, a miniature electric push rod, and a pressure sensor. The displacement sensors are set in pairs at one end of the inner cavity of the sleeve 51, which can detect the diameter change of the bare copper wire in real time. The pressure sensor is installed on the arc-shaped grinding surface of the grinding block 54, which directly detects the contact pressure between the grinding block 54 and the surface of the bare copper wire. The two sets of sensors transmit signals to the central control system. The control system adjusts the extension and retraction of each grinding block 54 by the miniature electric push rod installed on the inner wall of the sleeve 51 and connected to the grinding block 54, so that the grinding block 54 and the surface of the bare copper wire maintain a constant pressure. At the same time, it automatically adapts the grinding range according to the diameter of the bare copper wire to avoid over-grinding and damaging the copper wire substrate or under-grinding and incomplete cleaning.

[0046] It is worth noting that, such as Figure 7 As shown:

[0047] The high-pressure spray unit 6 includes a spray box 61 fixed above the mounting frame 1. The spray box 61 has through holes on both sides for copper wires to pass through. An annular spray pipe 62 is installed inside the spray box 61 and is fitted on the outside of the copper wire. Multiple sets of spray holes 63 are evenly opened on the inner side wall of the annular spray pipe 62.

[0048] The high-pressure spray unit 6 also includes a cleaning medium tank 64 and a high-pressure water pump 65. The inlet of the high-pressure water pump 65 is connected to the cleaning medium tank 64, and the outlet of the high-pressure water pump 65 is connected to the annular spray pipe 62 through a connecting pipe, forming a 45° angle with the bare copper wire to ensure that the spray range covers the entire surface of the copper wire. The cleaning medium tank 64 stores environmentally friendly neutral cleaning solution, which can be recycled. The high-pressure water pump 65 pressurizes the cleaning solution and delivers it to the annular spray pipe 62, which sprays the surface of the bare copper wire with high pressure through the spray holes 63 to wash away the copper powder, residual oil and dust generated during polishing. At the same time, the cleaning solution has an anti-rust function and can form a thin protective film on the surface of the copper wire to prevent secondary oxidation after cleaning. The bottom of the spray tank 61 is connected to a drain pipe 13 for recycling the used cleaning solution. The recycled cleaning solution is filtered and settled before being transported back to the cleaning medium tank 64 to achieve recycling, reduce consumable costs and environmental pollution.

[0049] In a further preferred embodiment, such as Figure 8 As shown:

[0050] A guide assembly 9 is provided between the wire feeding structure 2 and the pre-processing module to horizontally limit the copper wire. The guide assembly 9 includes two sets of horizontal constraint units and one set of vertical adjustment units. The horizontal constraint unit includes two sets of fixed shafts 91 fixed to the top of the mounting frame 1. A mounting frame 92 is fixed on the fixed shaft 91. A horizontal guide wheel 93 that is in contact with the copper wire is rotatably arranged on the fixed shaft 91 within the mounting frame 92. The vertical adjustment unit includes a fixed frame 94 located at the front end of the horizontal constraint unit. A movable frame 95 is slidably arranged on the fixed frame 94. A vertical guide wheel 96 located inside the movable frame 95 is movably arranged on the fixed frame 94. The vertical guide wheel 96 moves back and forth on the fixed frame 94 to adapt to the front and rear wire feeding operations of the copper wire winding, and to prevent the copper wire from falling off the horizontal guide wheel 93 during wire feeding. The two sets of horizontal guide wheels 93, together with the drive wheel 32, provide horizontal support for the copper wire, maintain the horizontality of the copper wire, and prevent excessive descent during the conveying process.

[0051] Between the two sets of horizontal constraint units, a tensioning unit is also provided to tension the copper wire. The tensioning unit includes an adjusting cylinder 10 fixed to the upper end of the mounting frame 1. A fixed frame 11 is installed on the movable end of the adjusting cylinder 10. A buffer wheel 12 is rotatably arranged inside the fixed frame 11 and is attached to the outer side of the copper wire.

[0052] In addition, such as Figure 2 As shown:

[0053] The detection unit 8 includes a ring-shaped detection seat and a ring-shaped lamp holder. The ring-shaped lamp holder and the ring-shaped detection seat are coaxially arranged on the outside of the copper wire. A ring-shaped laser light strip is installed on the ring-shaped detection seat. A ring-shaped photoresistor is also installed inside the ring-shaped detection seat. The ring-shaped laser light strip is fixedly installed on the ring-shaped inclined surface of the ring-shaped lamp holder, emitting a laser beam at a 45° angle to the bare copper wire. The laser beam is reflected by the surface of the bare copper wire to the photosensitive surface of the ring-shaped photoresistor of the ring-shaped detection seat. The photoresistor converts the reflected light signal into an electrical signal and transmits it to the central control system. The control system analyzes the uniformity of the reflected light signal to determine whether there are defects such as uncleaned oxide layers or scratches on the surface of the bare copper wire. If a defect is detected, the system automatically adjusts the grinding pressure of the grinding unit 5, the spraying pressure of the spraying unit, and the wire feeding speed, and coordinates with the post-processing module until the defect is eliminated.

[0054] The equipment is also equipped with a central control system, which uses a PLC controller and is electrically connected to the drive structure 3, the wire feeding structure 2, the heating unit 7, the wiping unit 4, the grinding unit 5, the high-pressure spraying unit 6, and the detection unit 8. The central control system is used to receive detection signals from each mechanism, send control commands, and realize the fully automated operation of the equipment.

[0055] The outer sides of the horizontal guide wheel 93, the vertical guide wheel 96, and the drive wheel 32 are all equipped with elastic rubber rings. The surface of the rubber rings is provided with anti-slip texture. When clamping copper wires of different diameters, the rubber rings are squeezed and indented, so that the distance between the paired horizontal guide wheel 93, vertical guide wheel 96 and drive wheel 32 is less than the diameter of the copper wire. This not only protects the outer wall of the copper wire during the copper wire transportation process, but also stabilizes the copper wire transportation.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
