Description

Technical Field

[0001] This invention relates to the field of copper manufacturing technology, and more specifically, to an apparatus for preparing highly conductive copper flexible connecting wires. Background Technology

[0002] In related technologies, flexible conductive connection components (soft connections) are key components for achieving high current conduction and mechanical vibration buffering in fields such as power transmission, new energy battery systems, and high-current equipment connections. They must simultaneously meet core performance requirements such as low resistance, high current carrying capacity, fatigue resistance, and long-term reliability. Copper-based materials (especially pure copper or high-purity copper) are the preferred material for soft connection conductors due to their excellent conductivity and ductility. To improve the flexibility and bending life of soft connections, copper stranded wires made of multiple strands of fine copper wire are widely used. These significantly reduce the risk of metal fatigue by dispersing stress. However, the stranded wire structure greatly increases the exposed surface area of ​​copper, making it prone to forming an insulating oxide layer in air or humid environments. This leads to increased contact resistance, abnormal temperature rise, and ultimately, deterioration of conductivity or even connection failure.

[0003] Existing technologies for anti-oxidation treatment after flexible interconnect wire forming suffer from low process efficiency. For example, when spraying after stranding, an additional drying process is required, leading to a longer production cycle. Alternatively, if anti-oxidation treatment is not performed initially, and the oxide layer is removed later, the quality of the copper material will be compromised. To address this issue, some copper flexible interconnect wires now employ a solution to temporarily isolate oxygen during intermediate manufacturing processes, balancing economy and effectiveness. This involves applying a controllable oil film coating while the copper conductor is still uncut, thus providing more effective anti-oxidation protection and improving the conductivity of the copper flexible interconnect wire. Therefore, a manufacturing apparatus for high-conductivity copper flexible interconnect wires has been proposed. Summary of the Invention

[0004] This invention provides an apparatus for preparing high-conductivity copper flexible interconnects. This apparatus can solve the problem mentioned in the background art of low process connection efficiency in the prior art when performing anti-oxidation treatment after the flexible interconnect is formed.

[0005] To achieve the above objectives, this solution provides a fabrication apparatus for high-conductivity copper flexible interconnect wires, including a first winding wheel that releases uncoated copper wires and a second winding wheel that receives and drives coated copper wires to move. A servo motor is mounted on the side of the second winding wheel, and an oiling assembly is provided between the first winding wheel and the second winding wheel. The oiling assembly includes a support frame and a first coating wheel and a second coating wheel mounted on the support frame. The first coating wheel includes an outer shell fixedly mounted above the support frame. A rotating wheel is rotatably mounted inside the outer shell.

A return spring is installed on the inner side of the telescopic sleeve, and a guide post is fixedly installed on the side of the telescopic sleeve. The guide post is slidably engaged with the wire annular groove.

[0008] Optionally, the support frame is provided with a homogenization component, which includes an air blower located between the first coating wheel and the second coating wheel. A push-pull piston rod is slidably installed inside the air blower. A heater is provided in the air blower. An air blowing port is opened at the top of the air blower. First air supply pipes are connected to both sides of the lower end of the air blower. An air inlet one-way valve is installed at the bottom of the air blower. A heating chamber is provided at the bottom of the outer shell. The anti-oxidation oil pool is located in the heating chamber, and a heat insulation layer is installed at the bottom of the anti-oxidation oil pool. The other end of the first air supply pipe is connected to the heating chamber.

[0009] Optionally, a heat-blowing one-way valve is installed at the air blowing port, and a heat-dissipating one-way valve is installed at the opening of the first air supply pipe.

[0010] Optionally, the bottom of the push-pull piston rod is connected to an extension column, an L-shaped connecting arm is fixedly installed at the bottom end of the extension column, a vertical plate is fixedly installed at the top of the other end of the L-shaped connecting arm, and a drive rack is provided on the side of the vertical plate.

[0011] Optionally, a transmission shaft is rotatably mounted on the inner wall of the outer casing, and a full gear and a toothed gear are fixedly mounted on the end of the transmission shaft, wherein the toothed gear is configured to have only half a tooth.

[0012] Optionally, a reversing cylinder is rotatably installed inside the telescopic sleeve. One end of the reversing cylinder is fixedly connected to the sponge coating brush head, and a conversion gear ring is fixedly sleeved on the other end of the reversing cylinder. The conversion gear ring intermittently meshes with the toothed gear.

[0013] Optionally, an annular groove is provided on the inner side of the telescopic sleeve near the conversion gear ring, and a spiral spring is provided in the annular groove. One end of the spiral spring is fixedly engaged with the telescopic sleeve, and the other end of the spiral spring is fixedly engaged with the reversing cylinder.

[0014] Optionally, one end of the return spring is connected to the telescopic sleeve, the other end of the return spring is fixedly connected to the outer end of the fixed rod, and the sponge coating brush head is fixedly installed on the outer end of the telescopic sleeve.

[0015] The high-conductivity copper flexible connector fabrication device provided by the above technical solution is used as follows: 1. By utilizing the symmetrically arranged first and second coating wheels, combined with the arc transition design of the wire ring groove and the concave arc part, oiling is ensured. When the copper wire passes through the oiling area between the two coating wheels, the sponge coating brush head achieves precise control of the oiling thickness through the rotation drive of the rotating wheel and the radial adjustment of the telescopic rod. Furthermore, through the return spring of the telescopic rod and the sliding engagement of the guide post, the sponge coating brush head achieves flexible contact with the copper wire, which not only ensures the friction coating effect during the oiling process, but also reduces the mechanical resistance when the copper wire passes through, and improves the continuity of the oiling process. 2. When the sponge coating brush head comes into contact with the copper wire, the push-pull piston rod moves upward. Utilizing the homogenization component, air can be blown onto the oil film applied to the copper wire. The 50℃-60℃ warm air agitation promotes the rapid diffusion of oil film molecules, allowing the lubricating oil to spread quickly and form a uniform thin layer. This avoids localized protection failure due to thickness differences. Furthermore, when the push-pull piston rod moves downward, the temperature stabilizes at around 40℃ when the heat is conducted to the anti-oxidation oil pool. This temperature range reduces the apparent viscosity of the high-viscosity lubricating oil, enhances its fluidity, and promotes the orderly arrangement of coating molecules through thermodynamic assistance. Combined with the rotational coating of the sponge coating brush head, it facilitates coating thickness control, significantly improving the yield and long-term conductivity stability of the high-conductivity copper flexible interconnect. 3. When the push-pull piston rod moves up and down, the vertical plate is driven to move synchronously through the L-shaped connecting arm, causing the sponge coating brush head to rotate 180 degrees. The rotation causes the concentrated oil on the side of the sponge coating brush head away from the copper wire to flip to the contact surface, realizing the effective utilization of the oil, reducing the uneven coating caused by oil accumulation, further improving the uniformity of the oil film thickness on the surface of the copper wire, and further improving the preparation efficiency and quality stability of the high conductivity copper flexible connector.

The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings indicate the same or similar elements, which will not be repeated here.

[0027] In this solution, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this solution based on the specific circumstances.

[0028] According to some embodiments of this solution, an apparatus for fabricating highly conductive copper flexible interconnect wires is provided, with reference to... Figures 1-7 As shown, the apparatus for preparing a high-conductivity copper flexible connector includes a first winding wheel 110 for releasing uncoated copper wires and a second winding wheel 120 for receiving and driving the coated copper wires. A servo motor 130 is mounted on the side of the second winding wheel 120. The servo motor 130 is configured as a geared motor and drives the second winding wheel 120 to rotate.

[0029] An oiling assembly is provided between the first take-up reel 110 and the second take-up reel 120. The oiling assembly includes a support frame 200 and a first coating wheel 210 and a second coating wheel 220 disposed on the support frame 200. The first coating wheel 210 includes an outer shell 221 fixedly mounted above the support frame 200. A rotating wheel 222 is rotatably mounted inside the outer shell 221. Several sponge coating brush heads 223 are arranged in a circular array on the outer side of the rotating wheel 222 for coating the copper wires passing through. An anti-oxidation oil pool 224 is provided at the bottom of the outer shell 221, and the anti-oxidation oil pool 224 contains an existing anti-oxidation oil agent.

[0030] The second applicator 220 is symmetrically arranged with the first applicator 210 and has the same internal structure.

[0031] A drive motor is mounted on the outside of the second applicator 220. The drive motor is configured as an intermittently operating geared motor. The output shaft of the drive motor drives the rotating wheel 222 inside the second applicator 220 to rotate. The output shaft of the drive motor also drives the rotating wheel 222 inside the first applicator 210 to rotate via a transmission belt pulley.

[0032] Thus, as the rotary wheel 222 rotates, the sponge coating brush head 223 passes through the anti-oxidation oil pool 224 one by one, and then comes into contact with the copper wire one by one, achieving flexible contact between the sponge coating brush head 223 and the copper wire, ensuring the friction coating effect during the oiling process.

[0033] In addition, a limiting ring 225 is integrally provided on the inner wall of the outer casing 221, and an oiling port 226 is provided on the side of the outer casing 221. The two oiling ports 226 are close to each other and symmetrically arranged. A wire ring groove 227 is provided on the side wall of the limiting ring 225, and a concave arc-shaped part 228 is provided near the oiling port 226 of the wire ring groove 227.

[0034] Specifically, see Figure 5 A telescopic rod 229 is connected between the rotating wheel 222 and the sponge coating brush head 223. The telescopic rod 229 includes a fixed rod 2291 fixedly installed with the rotating wheel 222 and a telescopic sleeve 2292 slidably sleeved on the outside of the fixed rod 2291. A return spring 2293 is installed on the inner side of the telescopic sleeve 2292. The sponge coating brush head 223 is fixedly installed on the outer end of the telescopic sleeve 2292. A guide post 2294 is fixedly installed on the side of the telescopic sleeve 2292. The guide post 2294 slidably engages with the wire ring groove 227.

[0035] When the guide post 2294 slides to the concave arc-shaped part 228, the sponge coating brush head 223 retracts towards the rotating wheel 222 along with the telescopic sleeve 2292.

[0036] As the sponge coating brush head 223 moves from being coated with oil to the oiling port 226, it absorbs excess oil and then flits it out by squeezing against the inner wall of the outer casing 221.

[0037] Furthermore, if the coating thickness on the copper wires is uneven, a thinner oil film will result in insufficient oxidation resistance for the copper flexible connector, affecting its high conductivity; conversely, an excessively thick oil film will cause the copper wires to stick together during winding, affecting subsequent use. To address this issue, a homogenization component is provided on the support frame 200, see [link to component description]. Figure 2 and Figure 4 The homogenization component includes an air blower 310 located between the first coating wheel 210 and the second coating wheel 220. A push-pull piston rod 320 is slidably installed inside the air blower 310. A drive mechanism is provided at the bottom of the push-pull piston rod 320. The drive mechanism is set as an electric push rod or other existing reciprocating push-pull mechanism.

[0038] An air blower 310 is equipped with a heater, which is a conventional electric heating device. An air outlet 330 is located at the top of the air blower 310. First air supply pipes 340 are connected to both sides of the lower end of the air blower 310. One-way air inlet valves 350 are installed on the sides and bottom of the air blower 310. A heating chamber 360 is located at the bottom inside the outer casing 221. An anti-oxidation oil tank 224 is located within the heating chamber 360, and a heat insulation layer 370 is installed at the bottom of the anti-oxidation oil tank 224. The other end of the first air supply pipe 340 is connected to the heating chamber 360. The heat insulation layer 370 is a stainless steel insulation layer or other existing insulation layer.

[0039] A heat-blowing one-way valve 331 is installed at the air outlet 330, and a heat-dissipating one-way valve 341 is installed at the outlet of the first air supply pipe 340.

[0040] Furthermore, to address the issue that when the sponge coating brush head 223 comes into contact with the copper wire, the oil in the sponge coating brush head 223 tends to pool on the other side of the contact surface, leading to discontinuous coating or requiring a shorter coating time for the sponge coating brush head 223, see... Figure 6 The bottom of the push-pull piston rod 320 is connected to an extension column 410. An L-shaped connecting arm 420 is fixedly installed at the bottom of the extension column 410. A vertical plate 430 is fixedly installed at the top of the other end of the L-shaped connecting arm 420. A drive rack 440 is provided on the side of the vertical plate 430.

[0041] A drive shaft 450 is rotatably mounted on the inner wall of the outer casing 221. A full gear (not shown) and a toothed gear 460 are fixedly mounted at the end of the drive shaft 450. The toothed gear 460 is configured as a gear with only half a tooth, and the drive rack 440 intermittently meshes with the full gear.

[0042] The telescopic sleeve 2292 has a rotating reverse cylinder 470 inside. One end of the return spring 2293 is connected to the telescopic sleeve 2292, and the other end of the return spring 2293 abuts against the reverse cylinder 470. One end of the reverse cylinder 470 is fixedly connected to the sponge coating brush head 223, and the other end of the reverse cylinder 470 is fixedly sleeved with a conversion gear ring 480. The conversion gear ring 480 intermittently meshes with the toothed gear 460.

[0043] Specifically, an annular groove is provided on the inner side of the telescopic sleeve 2292 near the conversion gear ring 480, and a spiral spring 490 is provided in the annular groove. One end of the spiral spring 490 is fixedly engaged with the telescopic sleeve 2292, and the other end of the spiral spring 490 is fixedly engaged with the reversing cylinder 470.

[0044] Through the above technical solution, the high-conductivity copper flexible connector preparation device provided in this solution, during use, involves the push-pull piston rod 320 moving up and down reciprocally. When the push-pull piston rod 320 moves upward, the air in the air blower 310 is heated by the heater, maintaining a temperature between 50 and 60 degrees Celsius. The warm air above the push-pull piston rod 320 is sprayed upward onto the copper wire through the air blower 330. The gentle warm air blows onto the oil film on the surface of the copper wire, enhancing the fluidity of the grease and promoting the rapid spread of the oil film into a uniform thin layer, avoiding uneven thickness that could lead to protective failure. At the same time, the airflow carries away the volatile solvents in the grease, forming a non-fluid dynamic protective film on the surface, preventing the oil film from sticking or contaminating the equipment during handling and winding. Furthermore, at this time, a negative pressure is generated below the push-pull piston rod 320, and the air inlet one-way valve 350 at the bottom of the air blower 310 opens to replenish the air.

[0045] When the push-pull piston rod 320 moves downward, the warm air below it is forced into the heated chamber 360. The air inlet check valve 441 automatically opens. Through the heat insulation layer 370, the heat from the warm air reaches the anti-oxidation oil pool 224 at around 40 degrees Celsius, providing lubrication during oiling, reducing paint viscosity, enhancing fluidity, and promoting uniform coating spread. Simultaneously, the air inlet check valve 350 on the side of the air blower 310 opens to replenish air to the area above the push-pull piston rod 320.

[0046] Furthermore, when the piston rod 320 moves up and down, it causes the vertical plate 430 to move up and down, which in turn causes the toothed gear 460 to rotate. When the toothed gear 460 rotates, it drives the conversion gear ring 480 to rotate 180 degrees through half of its teeth. This causes the reversing cylinder 470 to rotate the sponge coating brush head 223 180 degrees, so that the oil collected on the side of the sponge coating brush head 223 away from the copper wire is transferred to the side that is in contact with it, thereby improving the utilization rate of the coating oil and further improving the preparation efficiency of the high conductivity copper flexible connection wire.

[0047] Thus, when the copper wire passes through the oiling area between the first coating wheel 210 and the second coating wheel 220, the sponge coating brush head 223 controls the oiling thickness through the rotation drive of the rotating wheel 222 and the radial adjustment of the telescopic rod 229. Combined with the heat insulation of the anti-oxidation oil pool 224 by the heating chamber 360, the viscosity of the lubricating oil is ensured to be stable. With the airflow homogenization effect of the air blower 310, the oiling layer on the surface of the copper wire is finally made uniform and dense, avoiding local missed coating or excessive thickness, and improving the finished product qualification rate of high conductivity copper flexible connector wire.

[0048] It should be noted that when the toothless part of the missing tooth gear 460 is opposite to the conversion gear ring 480, the elastic potential energy of the spiral spring 490 completes the reset of the conversion gear ring 480 and the sponge-coated brush head 223.

[0049] The preferred embodiments of this solution have been described in detail above with reference to the accompanying drawings. However, this solution is not limited to the specific details in the above embodiments. Within the scope of the technical concept of this solution, various simple modifications can be made to the technical solution, and these simple modifications all fall within the protection scope of this solution.

[0050] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this solution will not describe the various possible combinations separately.

[0051] Furthermore, various implementations of this solution can be combined in any way, as long as they do not violate the spirit of this solution, they should also be regarded as the content disclosed in this solution.
