[0002] High-precision copper wire is often used in applications that require extremely high reliability and conductivity, such as precision electronics, aerospace vehicles, medical devices, high-performance computers, telecommunications infrastructure, and high-end automotive electronic systems.

[0003] During the cutting process, the copper wire is exposed to the air, especially under high temperature conditions, and an oxidation reaction easily occurs to generate a copper oxide layer, which has a negative impact on the conductivity of the copper wire. After the copper wire is cut, its incision is exposed and it is easy to oxidize after being stored for a long time. When the copper wire is used, the end face often requires additional treatment to remove the oxide layer to ensure the conductivity of the copper wire end face and avoid virtual connection of the wire, which adds additional cost and time.

[0013] As a preferred copper wire cutting device of the present invention, a limiting flange is provided on the side end surface of the second copper wire fixing seat.

[0014] A method for using a copper wire cutting device comprises the following steps: Step 1, pre-place a certain amount of paraffin in the film coating groove, start the electric heating wire, and heat the second piston through the electric heating wire, so that the second piston heats the paraffin on its upper end to keep it molten, so that a layer of paraffin film can be coated on the surface of the copper tube after cutting is completed; Step 2: Place the copper wire in the copper wire positioning groove of the first copper wire fixing seat, start the hydraulic telescopic rod to drive the cutter to move downward to cut the copper wire, and trigger the feeding mechanism to add paraffin balls to the coating groove to ensure that there is sufficient paraffin in the coating groove; Step 3: After the cutting is completed, the hydraulic telescopic rod drives the cutter to reset and prepare for the next cutting. During the resetting process, the cooling mechanism is triggered to cool the surface of the copper wire after cutting, so that the molten paraffin on the surface solidifies quickly, thereby forming a wax seal.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses a coating mechanism so that during the cutting process of the equipment, the copper wire is located in the molten paraffin in the coating groove, which effectively isolates the contact between the copper wire incision and the air, thereby avoiding the oxidation problem caused by the thermal effect generated during the cutting process. Once the copper wire is cut, both ends of the copper wire will be immediately covered with paraffin. This layer of paraffin film can protect the copper wire incision from oxygen, moisture and other pollutants in the air, thereby maintaining the purity and conductivity of the copper wire for a long time. This instant coating technology is not only suitable for instant protection during the production process, but also can provide long-term anti-corrosion protection for subsequent transportation and storage, ensuring the quality of the product in the entire supply chain. When the copper wire is used, there is no need to polish the cut surface, which improves the convenience of use.

[0016] 2. The present invention arranges a feeding mechanism on the workbench. When the paraffin is consumed, the feeding mechanism can automatically replenish the paraffin balls. These paraffin balls are sent into the coating tank through the feeding roller to ensure that the supply of paraffin is always sufficient. This automatic feeding mechanism eliminates the need for manual addition of paraffin, reduces downtime, and improves the continuity and overall efficiency of the production line. By accurately controlling the feeding amount, it can avoid excessive or insufficient situations and ensure that the amount of paraffin in the coating tank is maintained at an ideal level, thereby optimizing the production process and ensuring the continuity and automation of equipment processing and production.

[0017] 3. The present invention arranges a cooling mechanism on the second copper wire fixing seat, utilizes a refrigerant to rapidly reduce the temperature of the copper wire surface, and rapidly hardens the paraffin film. The hardened paraffin film makes it easier to take the copper wire out of the coating groove, thus reducing the waiting time and speeding up the entire production cycle. The rapid response of the cooling mechanism means that the equipment can quickly prepare for the next round of cutting tasks, further improving the overall efficiency of the production line.

[0020] See also Figure 1-Figure 10 , a copper wire cutting device, comprising a workbench 1 and a cutting mechanism 2, wherein the workbench 1 is provided with a coating mechanism 3, a feeding mechanism 4 and a cooling mechanism 5; The cutting mechanism 2 includes a hydraulic telescopic rod 201, a slide 202 and a cutter 203. The hydraulic telescopic rod 201 is fixedly mounted on the upper end of the workbench 1, the slide 202 is mounted on the bottom of the hydraulic telescopic rod 201, and the cutter 203 is mounted on the bottom of the slide 202; The laminating mechanism 3 comprises a first copper wire fixing seat 301 and a second copper wire fixing seat 302 which cooperate with each other. The first copper wire fixing seat 301 is fixedly mounted on the workbench 1. A heating wire 3016 is arranged inside the first copper wire fixing seat 301. The second copper wire fixing seat 302 is movably mounted at the lower end of the slide 202. The feeding mechanism 4 includes a feeding box 401, a feeding roller 402 and a first paddle 403, and the feeding mechanism 4 is installed at the rear side of the laminating mechanism 3; The cooling mechanism 5 comprises a refrigerant bottle 501 , a nozzle 502 , a valve core 503 and a second paddle 504 . The cooling mechanism 5 is installed in the second copper wire fixing seat 302 . The refrigerant bottle 501 contains liquid carbon dioxide or liquid nitrogen.

[0021] When the first copper wire fixing seat 301 and the second copper wire fixing seat 302 cooperate, a copper wire positioning groove 3011 and a coating groove 3012 are formed. A sealing ring is provided on the inner end surface of the copper wire positioning groove 3011 to ensure the sealing between the copper wire and the first copper wire fixing seat 301 and the second copper wire fixing seat 302 to avoid leakage of paraffin melt. A piston cavity 3017 is provided on the upper end surface of the first copper wire fixing seat 301. A first piston 3013 and a first spring 3014 are provided in the piston cavity 3017. A movably connected second piston 3015 is provided in the coating groove 3012. The heating wire 3016 is located at the lower end of the second piston 3015. The bottom of the piston cavity 3017 is connected with the bottom of the coating groove 3012.

[0022] When the first piston 3013 is pressed downward, the first piston 3013 presses the air in the piston chamber 3017 into the bottom of the coating groove 3012, thereby moving the second piston 3015 upward, causing the paraffin melt in the coating groove 3012 to move upward and cover the surface of the copper wire. The copper wire is cut in the paraffin melt and isolated from the outside air to ensure that the end face after cutting does not come into contact with the air, thereby avoiding oxidation of the cut surface of the copper wire. The second piston 3015 is heated by the heating wire 3016 to keep the paraffin on its upper end in a molten state.

[0023] A guide rod 2021 is provided at the bottom of the slide 202, and a second spring 2022 is sleeved on the guide rod 2021. A guide hole 3021 cooperating with the positioning rod is provided on the first positioning seat. The first positioning seat and the slide 202 are elastically slidably connected through the guide rod 2021, the guide seat and the second spring 2022. A pressure block 2023 corresponding to the position of the first piston 3013 is provided at the bottom of the guide rod 2021. The pressure block 2023 passes through the first positioning seat for sliding connection, and the cutter 203 passes through the second positioning seat for sliding connection therewith.

[0024] When the first positioning seat cooperates with the second positioning seat, the slide 202 continues to feed downward, causing the cutter 203 and the pressure block 2023 to slide downward, so that the cutter 203 cuts the copper wire, and the pressure block 2023 squeezes the first piston 3013 to move downward. Under the action of air pressure, the second piston 3015 is lifted up, causing the liquid level of the molten paraffin at the upper end of the second piston 3015 to rise and completely cover the copper wire.

[0025] A storage chamber 4011 and a material transfer chamber 4012 are provided in the feed box 401, and a discharge port 4013 is provided on the side of the material transfer chamber 4012. The feed roller 402 and the first paddle 403 are installed in the material transfer chamber 4012 and are rotatably connected to the feed box 401. A shaft sleeve 4031 is provided on the side end face of the first paddle 403. The shaft sleeve 4031 is sleeved on the feed roller 402 and is rotatably connected to the feed box 401 through a one-way bearing. The shaft sleeve 4031 is elastically connected to the feed box 401 through a first torsion spring 404.

[0026] When the first paddle 403 is pressed down, the first paddle 403 can drive the feeding roller 402 to rotate through the shaft sleeve 4031, so that the feeding roller 402 moves the paraffin balls in the transfer chamber 4012 to move, so that they are discharged through the discharge port 4013. After the discharge is completed, the shaft sleeve 4031 moves upward and resets under the reset action of the first torsion spring 404, while the feeding roller 402 remains stationary under the action of the one-way bearing.

[0027] A limiting groove 4015 is provided on the front end surface of the feed box 401, and the first paddle 403 is installed in the limiting groove 4015. The upper end surface of the limiting groove 4015 is horizontally arranged, and the angle between the lower end surface and the upper end surface of the limiting groove 4015 is sixty degrees.

[0028] The limiting groove 4015 limits the downward rotation angle of the first paddle 403 and its reset angle, so as to avoid the first paddle 403 from rotating excessively downward and causing excessive feeding, and ensure that the first paddle 403 remains horizontal when resetting, so that when the first positioning seat is reset upward, it cooperates with the second paddle 504 on its side to push the second paddle 504 to rotate.

[0029] The side of the feeding roller 402 is provided with a material-discharging blade 4021 . The material-discharging blade 4021 is six groups of arc-shaped blades. The material-discharging blades 4021 are arranged in an equidistant circular array on the side of the feeding roller 402 . The discharge port 4013 is provided with a guide plate 4014 .

[0030] The included angle between adjacent material-discharging blades 4021 is sixty degrees. Each time the first paddle 403 is moved, a group of material-discharging blades 4021 completes one material discharge. The discharged paraffin balls fall into the coating groove 3012 under the guidance of the guide plate 4014, thereby replenishing the material and keeping the amount of paraffin melt in the coating groove 3012 relatively stable.

[0031] An air flow channel 5045 connected to the refrigerant bottle 501 is provided in the second copper wire fixing seat 302, and the nozzle 502 is fixedly installed at the bottom of the air flow channel 5045. A sliding hole is provided on the side wall of the air flow channel 5045, and the valve core 503 is inserted into the sliding hole and slidably connected to the second copper wire fixing seat 302.

[0032] When the valve core 503 is pulled out, the nozzle 502 is connected to the refrigerant bottle 501, and the refrigerant in the refrigerant bottle 501 is quickly sprayed out by the nozzle 502, so that the surface of the wire is quickly cooled, and the paraffin on the guide surface is quickly solidified and agglomerated, so that it is convenient for transportation.

[0033] A rotating shaft 5041 and a second torsion spring 5042 are provided on the side of the second paddle 504 . The second paddle 504 is elastically rotatably connected to the first copper wire fixing base via the rotating shaft 5041 and the second torsion spring 5042 . A rotatably connected connecting rod 5043 is provided between the second paddle 504 and the valve core 503 .

[0034] When the second paddle 504 rotates, the second paddle 504 pulls the valve core 503 through the connecting rod 5043, pulls out the valve core 503, connects the air flow channel 5045, and the refrigerant in the air flow channel 5045 is quickly ejected. After a short injection, the second paddle 504 is quickly reset under the reset action of the second torsion spring 5042 to prepare for the next action.

[0035] A limiting flange 5044 is disposed on the side end surface of the second copper wire fixing seat 302 .

[0036] The rotation angle of the second paddle 504 is limited by the limiting flange 5044, so that the second flange can only be flipped downward but not upward, so that when the second copper wire fixing seat 302 moves downward, the second paddle 504 presses down the first paddle 403, causing the first paddle 403 to rotate counterclockwise to trigger the feeding mechanism 4; when the second copper wire fixing seat 302 moves upward, the first paddle 403 presses down the second paddle 504, causing the second paddle 504 to move clockwise to trigger the cooling mechanism 5.

[0037] See also Figure 1-Figure 10 , a method for using a copper wire cutting device, comprising the following steps: Step 1, pre-place a certain amount of paraffin in the coating groove 3012, start the electric heating wire 3016, and heat the second piston 3015 through the electric heating wire 3016, so that the second piston 3015 heats the paraffin on its upper end to keep it in a molten state, ensuring that the molten paraffin can completely submerge the copper wire to prevent the copper wire end face from contacting the air during the cutting process, and a layer of paraffin film can be coated on the surface of the copper tube after the cutting is completed; Step 2, place the copper wire in the copper wire positioning groove 3011 of the first copper wire fixing seat 301, the position to be cut is located directly below the cutter 203, start the hydraulic telescopic rod 201, so that it drives the cutter 203 to move downward to cut the copper wire, when the hydraulic telescopic rod 201 drives the slide 202 to slide downward, the second copper wire fixing seat 302 is buckled with the first copper wire fixing seat 301, so that the coating groove 3012 becomes a semi-enclosed cavity with an opening at the top, and the slide 202 continues to feed downward, so that the pressure block 2023 presses the first piston 3013 downward, and the second piston 3015 slides upward under the action of air pressure, so that the paraffin melt submerges the copper wire, and the cutter 203 cuts the copper wire; During the descent of the slide 202, the first paddle 403 and the second paddle 504 cooperate to trigger the feeding mechanism 4. The second paddle 504 presses down the first paddle 403 under the action of the limiting flange 5044, so that the shaft sleeve 4031 on the first paddle 403 drives the feeding roller 402 to rotate, so that the paddle blade 4021 pushes the paraffin ball toward the discharge port 4013 and drops it into the positioning groove 3011, replenishing the paraffin in the coating groove 3012, and ensuring that the paraffin in the coating groove 3012 is sufficient and stable; Step 3, after the cutting is completed, the hydraulic telescopic rod 201 drives the cutter 203 to move upward and reset, preparing for the next cutting. During the resetting process, the first paddle 403 and the second paddle 504 cooperate to trigger the cooling mechanism 5 again. The first paddle 403 presses down the second paddle 504 under the action of the limit groove 4015, so that the second paddle 504 rotates clockwise along the rotating shaft 5041, thereby driving the valve core 503 to move through the connecting rod 5043, so that the nozzle 502 is briefly connected to the refrigerant bottle 501, and the liquid carbon dioxide or liquid nitrogen in the refrigerant bottle 501 is sprayed out, so that the cooling mechanism 5 cools down the surface of the copper wire after cutting, and the molten paraffin on the surface of the copper wire solidifies rapidly, thereby forming a wax seal, and then the cut wire is transported to the next process for packaging.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
