[0002] Enameled copper flat wire, as a special type of electromagnetic wire, plays an important role in the modern electrical industry due to its unique properties and wide range of applications. Flat conductors have gradually developed due to their advantages in specific applications. Insulating varnish is an important component of enameled copper flat wire, providing electrical insulation and physical protection. Insulating varnish is typically composed of resin, solvent, and additives. The resin is the base of the varnish, determining its insulation performance and thermal stability. Solvents are used to adjust the viscosity and flowability of the varnish, while additives are used to improve specific properties of the varnish, such as chemical resistance and abrasion resistance.

[0003] However, in actual use, the inventors found that the lacquer tends to accumulate at the edges of the flat wire, resulting in excessive local thickness and the formation of lacquer nodules, which makes it difficult to embed the enameled copper flat wire winding. Summary of the Invention

Then, the paint on the sides of the flat wire is spliced ​​and covered. The paint on the sides of the flat wire will not form ripple lines. The paint on the sides and edges of the flat wire is evenly coated and the paint surface is smooth. The edges of the flat wire will not accumulate paint and form paint nodules, thus improving the coating effect of the flat wire.

When coating copper flat wires of different specifications, it is convenient to replace the coating components of different sizes, and the adaptability is high. (2) In this invention, by setting up a rejection component and a repair component together, on the one hand, the protrusions on the surface of the flat wire can be automatically rejected during the advance of the flat wire, thereby improving the smoothness of the flat wire surface and facilitating the subsequent painting work.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] Example 1 like Figures 1-17 As shown, a layered coating high-strength enameled copper flat wire processing device with online surface repair includes a wire drawing machine 1, and a wire feeding mechanism 2, a correction mechanism 3, and an enameling mechanism 4 located behind the wire drawing machine 1. The enameling mechanism 4 includes a mold frame 41, and a first coating component 42 for coating the edges of the flat wire, a uniform component 43 for blowing the paint at the edges of the flat wire, and a second coating component 44 for coating the sides of the flat wire, which are sequentially arranged on the mold frame 41. The first coating component 42 coats the flat wire with paint at its edges and corners. The uniform coating component 43 blows the paint at the edges and corners of the flat wire evenly to both sides. The second coating component 44 coats the flat wire with paint on its four sides. The edges and sides of the flat wire are coated with paint separately, so that the flat wire is evenly coated with paint.

[0039] It should be noted that the wire drawing machine 1 adopts the existing flat wire drawing machine, and its structure and function will not be described in detail.

[0040] In this embodiment, the enameling mechanism 4 and the correction mechanism 3 work together to achieve the following: First, the edges and sides of the flat wire are coated with paint separately. The paint at the edges is first evenly spread to both sides to reduce excess paint at the edges. Then, the paint on the sides of the flat wire is applied in a splicing and covering manner. The paint on the sides of the flat wire will not form ripples. The paint on the sides and edges of the flat wire is evenly applied, and the paint surface is smooth. Paint will not accumulate at the edges of the flat wire to form paint nodules, thus improving the enameling effect of the flat wire. Second, the painting components can be detachably installed on the mold frame 41. The disassembly and assembly are relatively simple and the installation is reliable. When painting copper flat wires of different specifications, it is convenient to replace the painting components of different sizes, which has high adaptability.

[0041] In detail, the wire drawing machine 1 draws the copper rod into a high-strength oxygen-free copper flat wire. The wire feeding mechanism 2 transports the flat wire to the position of the correction mechanism 3. The detection component 31 detects the forming state of the outer surface of the flat wire and marks the unevenness of the outer surface of the flat wire. The removal component 32 removes the protrusions on the surface of the flat wire and collects the waste. The repair component 33 uses the waste to melt and repair the depressions on the surface of the flat wire. The wire feeding mechanism 2 transports the flat wire to the position of the enameling mechanism 4. The first coating component 42 coats the edges of the flat wire with paint. The uniform coating component 43 blows the paint at the edges of the flat wire evenly to both sides. The second coating component 44 coats the four sides of the flat wire with paint. The edges and sides of the flat wire are coated with paint separately to obtain the enameled copper flat wire product.

[0042] Furthermore, such as Figure 2 As shown, the transmission mechanism 2 includes: Upright plate 21, and several sets of the upright plates 21 are arranged on the frame; The wire feeding wheel 22 is rotatably mounted on the vertical plate 21. The wire feeding wheel 22 consists of two sets of clamping flat wires, ensuring stable feeding.

[0043] In this embodiment, the flat wire is sequentially conveyed to the workstations of the correction mechanism 3 and the enameling mechanism 4 through the wire feeding mechanism 2, and the clamping method is relatively stable.

[0044] In detail, the flat wire drawn by the wire drawing machine 1 is sequentially transported to the correction mechanism 3 and the enameling mechanism 4 via the wire conveying mechanism 2.

[0045] Furthermore, such as Figures 3-10 As shown, the correction mechanism 3 includes a detection component 31 disposed on the frame, a rejection component 32 disposed on the frame, and a repair component 33 disposed on the rejection component 32; The detection component 31 includes: A three-dimensional inspection instrument 311 is mounted on the frame; The marking rod 312 is raised and lowered on the three-dimensional detector 311 via a first hydraulic component 313.

[0046] It should be noted that the 3D inspection instrument 311 adopts the existing laser 3D profilometer, the structure and function of which will not be described in detail.

[0047] It is worth mentioning that the marker rod 312 uses a fluorescent marker pen from the existing technology, the structure and function of which will not be described in detail here.

[0048] In this embodiment, the detection component 31 can automatically identify the unevenness of the flat wire surface and use fluorescent markings to facilitate subsequent rejection and repair work.

[0049] In detail, the flat wire passes through the three-dimensional inspection instrument 311, which detects the surface forming condition of the flat wire in real time. When it detects protrusions and depressions on the surface of the flat wire, the first hydraulic component 313 drives the marking rod 312 to descend and fluorescently mark the protrusions and depressions on the surface of the flat wire.

[0050] Furthermore, such as Figures 4-10 As shown, the rejection component 32 includes: The machine base 3297 is slidably mounted on the frame via an electric slide table 3298; Lower module 321, wherein the lower module 321 is disposed on the machine base 3297; The upper module 322 is lifted and mounted on the machine base 3297 via a second hydraulic component 323, and is located directly above the lower module 321; Expansion slots 324, two sets of expansion slots 324 are respectively opened at the bottom of the upper module 322 and the top of the lower module 321, and the two sets of expansion slots 324 form a rejection channel; A first horizontal drive unit 325 is disposed inside the expansion slot 324 at the bottom of the upper module 322, and a second horizontal drive unit 326 is disposed inside the expansion slot 324 at the top of the lower module 321. U-shaped scraper 327, two sets of U-shaped scrapers 327 are respectively set on the output end of the first horizontal drive unit 325 and the output end of the second horizontal drive unit 326, and the two sets of U-shaped scrapers 327 are matched with the outer wall of the flat wire after docking; The U-shaped chip suction frame 328 is disposed on the output end of the first horizontal drive unit 325. The U-shaped chip suction frame 328 is provided with a first chip suction port 329, which is used to remove waste chips from the upper surface of the flat wire. The two lower ends of the U-shaped chip suction frame 328 are respectively provided with second chip suction ports 3291, which are used to remove waste chips from the expansion slot 324 at the top of the lower module 321. A melting box 3292 is disposed on the top of the upper module 322. A fan 3293 is disposed on the top of the upper module 322. The fan 3293 delivers the waste chips collected by the U-shaped chip suction frame 328 to the inside of the melting box 3292 through a hose. A spur gear 3294 is rotatably mounted on the output end of the second horizontal drive unit 326 via a hanging shaft. A sweeping rod 3295 is provided at the lower end of the hanging shaft. The sweeping rod 3295 is used to sweep the waste debris below the flat wire to both sides. The rack 3296 is disposed inside the expansion slot 324 at the top of the lower module 321 and is used to drive the spur gear 3294 to rotate the sweeping rod 3295.

[0051] It should be noted that the structure and function of the electric slide table 3298 are existing technologies and will not be described in detail here. The electric slide table 3298 drives the machine table 3297 with the lower module 321 and the upper module 322 at the same speed as the flat wire, that is, the machine table 3297 moves forward synchronously with the flat wire, which facilitates the processing of protrusions and depressions on the surface of the flat wire.

[0052] It is worth mentioning that the first horizontal drive unit 325 and the second horizontal drive unit 326 have the same structure, specifically including a lead screw, a threaded block and a motor. The motor drives the lead screw to rotate, and the lead screw drives the threaded block to move horizontally.

[0053] It should also be noted that the first suction port 329 of the U-shaped chip suction frame 328 is located directly above the U-shaped scraper 327 of the upper module 322, which facilitates timely removal of the waste chips removed by the U-shaped scraper 327 on the surface of the flat line.

[0054] It is also worth mentioning that the melting box 3292 is equipped with a heating module, which is a technology in the prior art, to heat the waste inside the melting box 3292 into molten copper. The melting box 3292 is equipped with a feeding port to facilitate the replenishment of copper material into the melting box 3292.

[0055] In this embodiment, the removal component 32 and the repair component 33 work together to automatically remove protrusions from the surface of the flat wire during its advance, improving the smoothness of the flat wire surface and facilitating subsequent painting work. The flat wire does not need to be stopped from being transported, so the painting process of the flat wire is not affected, ensuring the processing efficiency of the enameled copper flat wire. On the other hand, the waste removed from the surface of the flat wire can be collected and reused to fill the depressions on the surface of the flat wire, reducing material waste and improving economic efficiency.

[0056] In detail, after the identification unit detects the raised marks left on the four sides of the flat wire by the marking rod 312, the electric slide table 3298 drives the machine table 3297 to move forward synchronously with the flat wire according to the forward speed of the flat wire. The second hydraulic component 323 drives the upper module 322 to descend, so that the raised position is located inside the rejection channel. The first horizontal drive unit 325 and the second horizontal drive unit 326 simultaneously drive the U-shaped scraper 327 of the upper module 322 and the U-shaped scraper 327 of the lower module 321 to move horizontally synchronously. The two sets of U-shaped scrapers 327 remove the raised marks on the surface of the flat wire. At the same time, the first suction port 329 of the U-shaped chip suction frame 328 can promptly remove the waste chips removed from the upper surface of the flat wire. Meanwhile, the rack 3296 drives the spur gear 3294 to carry the sweeping rod 3295. Rotating, the sweeping bar 3295 sweeps the waste debris below the flat wire to both sides. The second suction ports 3291 at the two lower ends of the U-shaped suction frame 328 suck up the waste debris inside the expansion slot 324 at the top of the lower module 321. The blower 3293 sends the waste debris collected by the U-shaped suction frame 328 to the melting box 3292 through the hose. Then, the first horizontal drive unit 325 and the second horizontal drive unit 326 simultaneously drive the U-shaped scraper 327 of the upper module 322 and the U-shaped scraper 327 of the lower module 321 to move in opposite directions to reset, further sucking up the waste debris remaining in the removal channel. Then, the second hydraulic component 323 drives the upper module 322 to rise and reset, and the electric slide table 3298 drives the machine table 3297 to return to the reset, ready for the next use.

[0057] Furthermore, such as Figures 6-10 As shown, the repair component 33 includes: The identification unit is disposed on the side of the upper module 322 and is used to identify the mark left on the flat line by the marking rod 312; A shaping channel 331 is provided at one port of the rejection channel formed by the upper module 322 and the lower module 321; Two sets of heating plates 332 are respectively disposed at the top and bottom of the shaping channel 331; Heat exchange plate 333 is respectively disposed on both sides of the molding channel 331. A circulating cold water pipe is disposed inside the upper module 322 and is embedded in the back of the heat exchange plate 333. An automatic injection tube is disposed inside the upper module 322. The upper end of the automatic injection tube is connected to the melting box 3292, and the lower end of the automatic injection tube is connected to the molding channel 331.

[0058] It should be noted that the recognition unit consists of four sets of high-speed cameras in the prior art, which respectively recognize the raised and recessed marks left on the four sides of the flat line by the marking rod 312, and transmit the raised and recessed position information to the prior art control system. When the raised position information is recognized, the control system causes the upper module 322 to descend according to the forward speed of the flat line, so that the raised position is located in the rejection channel. When the recessed position information is recognized, the control system causes the upper module 322 to descend according to the forward speed of the flat line, so that the recessed position is located in the shaping channel 331.

[0059] It is worth mentioning that the structure and function of the electric heating plate 332 are existing technologies and will not be described in detail here.

[0060] It should also be noted that when the heating plate 332 is working, the circulating cold water pipe is not working, that is, no cold water source is supplied to the circulating cold water pipe. When the heating plate 332 stops working, the shaped flat wire needs to be cooled and solidified quickly. Cold water source is supplied to the circulating cold water pipe to cool and solidify the flat wire quickly before demolding. It is also worth mentioning that the structure and function of the automatic injection tube are existing technologies and will not be described in detail here. According to the degree of concavity of the flat wire, copper liquid is automatically and quantitatively injected into the shaping channel 331.

[0061] In this embodiment, the repair component 33 can automatically fill the depressions on the surface of the flat wire, resulting in a good repair effect and improving the smoothness of the flat wire surface.

[0062] In detail, after the identification unit detects the recessed marks left on the four sides of the flat wire by the marking rod 312, the electric slide table 3298 drives the machine table 3297 to move forward synchronously with the flat wire according to the forward speed of the flat wire. The second hydraulic component 323 drives the upper module 322 to descend, so that the recessed position is located inside the shaping channel 331. The electric heating plate 332 heats and melts the flat wire inside the shaping channel 331. The automatic injection pipe automatically injects the copper liquid inside the melting box 3292 into the shaping channel 331 according to the degree of recess on the surface of the flat wire. Then, the electric heating plate 332 stops working and cold water is introduced into the circulating cold water pipe. The circulating cold water quickly cools and shapes the flat wire inside the shaping channel 331 through the heat exchange plate 333. Then, the second hydraulic component 323 drives the upper module 322 to rise and reset, and the electric slide table 3298 drives the machine table 3297 to return to the reset position, ready for the next use.

[0063] Furthermore, such as Figures 11-17 As shown, the first painting assembly 42 includes a sleeve 422 mounted on the mold frame 41 via a mounting member 421, an expansion cylinder 423 mounted at the port of the sleeve 422, four sets of corner plates 424 elastically mounted inside the expansion cylinder 423 and respectively matching the angle of the flat wire, and a sponge block mounted on the corner plate 424. The first painting assembly 42 further includes: A fixing ring 425 is disposed inside the expanding cylinder 423 via a connecting rod; The slide rod 426, four sets of the slide rod 426 are arranged through the fixed ring 425, the corner plate 424 is respectively arranged at one end of the slide rod 426, and a first elastic element 427 is arranged between the other end of the slide rod 426 and the outer wall of the fixed ring 425; The mold frame 41 is divided into several groups and arranged on the machine frame, and the mounting component 421 includes: Limiting block 4211, the limiting block 4211 is disposed on the sleeve 422, and the sleeve 422 is slidably disposed on the limiting strip hole 4212 of the mold frame 41 through the limiting block 4211; A limiting rod 4213 is provided on the limiting block 4211 by means of an ear plate. A second elastic element 4214 is provided between one end of the limiting rod 4213 and the ear plate. Insertion hole 4215 is formed on the mold frame 41, and one end of the limiting rod 4213 is adapted to the insertion hole 4215.

[0064] It is worth mentioning that when it is necessary to change the mold, the long rod tool is used manually to press down the limiting rod 4213 so that the limiting rod 4213 is disengaged from the insertion hole 4215 on the mold frame 41, and then the sleeve 422 is manually removed horizontally from the limiting strip hole 4212 of the mold frame 41.

[0065] In this embodiment, the first painting component 42 can automatically paint the four corners of the flat wire, apply paint elastically, ensure uniform paint application, and facilitate mold replacement to adapt to flat wires of different specifications.

[0066] In detail, when installing the mold, manually press the limiting rod 4213, and then manually slide the limiting block 4211 on the sleeve 422 horizontally into the limiting strip hole 4212 of the mold frame 41. When the limiting rod 4213 moves to the insertion hole 4215 on the mold frame 41, the limiting rod 4213 is inserted into the insertion hole 4215 on the mold frame 41 under the elastic force of the second elastic element 4214, thereby installing and fixing the mold. When the flat line advances through the mold, the sponge blocks on the four corner plates 424 paint the four edges of the flat line.

[0067] Furthermore, such as Figures 15-17 As shown, the homogenizing component 43 includes: Anti-slip wheels 431, two sets of anti-slip wheels 431 are respectively rotatably mounted between the two corner plates 424 on the same side via a U-shaped frame, and respectively contact the two sides of the flat line; Air box 432, two sets of air boxes 432 are respectively arranged between the two corner plates 424 on the same side, and the air box 432 is provided with an air inlet; A shaft 433 is rotatably disposed inside the air inlet, and a fan blade 434 is provided at one end of the shaft 433, which is located inside the air inlet. A first bevel gear 435 is disposed at the other end of the shaft 433; The second bevel gear 436 is mounted on the U-shaped frame and coaxially mounted with the anti-slip wheel 431, and is used to drive the first bevel gear 435. Air outlet 437, several sets of the air outlet 437 are arranged on the air box 432, and are directly opposite the corner of the flat line.

[0068] In this embodiment, the uniform coating component 43 can automatically and evenly spread the paint at the corners of the flat line to both sides during the forward movement of the flat line, reducing the amount of excess paint at the corners of the flat line and preventing excessive paint accumulation at the corners of the flat line from forming paint nodules.

[0069] In detail, during the forward movement of the flat line, the anti-slip wheel 431 is driven to rotate on the side of the flat line. The anti-slip wheel 431 drives the fan blade 434 to rotate through the second bevel gear 436, the first bevel gear 435, and the shaft 433. This causes the fan blade 434 to send air into the air box 432, which in turn blows air through the air outlet 437 to the corners of the flat line, spreading the paint at the corners of the flat line evenly to both sides.

[0070] Furthermore, such as Figures 11-15 As shown, the second painting assembly 44 includes: Mold core 441, which is disposed inside the sleeve 422 and is used for coating the side of the flat wire with paint; The paint box 442 is mounted on the frame and is connected to the mold core 441 and the sponge block on the corner plate 424 via flexible hoses.

[0071] In this embodiment, the second painting component 44 can automatically paint the four sides of the flat wire and cover the boundary lines where the paint spreads to both sides at the corners of the flat wire, thus preventing the paint from forming ripple lines on the four sides of the flat wire and increasing the smoothness of the paint surface.

[0072] In detail, after the paint at the corners of the flat wire spreads evenly to both sides, it continues to advance into the mold core 441. The mold core 441 paints the four sides of the flat wire and covers the boundary lines of the paint spreading to both sides at the corners of the flat wire.

[0073] Example 2 like Figure 18As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: Furthermore, such as Figure 18 As shown, a method for processing high-strength enameled copper flat wire includes the following steps: Step 1, wire drawing process: using wire drawing machine 1, the copper rod is drawn into a high-strength oxygen-free copper flat wire through the mold. The drawing speed is 50-80m / min. During the drawing process, the concentration of the emulsion is controlled within the range of 5.5%-6.5%, which has the effect of cooling, lubrication and cleaning of the flat wire. Step 2, correction process: The wire feeding mechanism 2 conveys the flat wire to the position of the correction mechanism 3. The detection component 31 detects the forming state of the outer surface of the flat wire and marks the unevenness of the outer surface of the flat wire. The removal component 32 removes the protrusions on the surface of the flat wire and collects the waste. The repair component 33 uses the waste to melt and repair the depressions on the surface of the flat wire. Step 3, annealing process: The flat wire is passed through the enameling machine annealing furnace to change the flat wire from a hard state to a soft state. Then the flat wire is cleaned, cooled and dried. Step four, the painting process: the first painting component 42 applies paint to the edges and corners of the flat wire, the uniform coating component 43 blows the paint from the edges and corners of the flat wire evenly to both sides, the second painting component 44 applies paint to the four sides of the flat wire, and the edges and sides of the flat wire are coated with paint separately, so that the flat wire is evenly coated with paint, and the number of painting passes is 9-12.
