Description

Technical Field

[0001] This utility model belongs to the technical field of electromagnetic wire production equipment, specifically an electromagnetic wire coating and curing production line. Background Technology

[0002] Electromagnetic wire is a conductive metal wire with an insulating layer, mainly used in the manufacture of windings for electromagnetic equipment such as motors, transformers, electromagnets, and inductors. It is a key material for realizing electromagnetic energy conversion or signal transmission. Its core function is to generate a magnetic field when energized, or to induce a current when the magnetic field changes. Therefore, it is widely used in fields such as power, electronics, communications, and aerospace.

[0003] An electromagnetic wire coating and curing production line is an automated continuous production equipment that realizes the coating and curing of insulating varnish on the surface of electromagnetic wires. The processing is completed by the coordinated operation of conveying, coating, and curing devices.

[0004] Traditional coating tubes (painting molds) and painting devices are mostly fixed with bolts or interference fits. When replacing them, it is necessary to disassemble the flange, disconnect the paint pipeline, and even disassemble the entire painting base. The replacement of a single mold usually takes 10-30 minutes. If the production line needs to switch to different diameter electromagnetic wires (such as from 0.5mm to 1.2mm), the corresponding diameter coating tube needs to be replaced. Frequent changes can lead to downtime of up to 15%-20% of the production line, which seriously affects the production capacity. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a coating and curing production line for electromagnetic wires.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The coating and curing production line for electromagnetic wires of this utility model includes a lower fixed base assembly, the lower fixed base assembly is provided with a disassembly and assembly component, the disassembly and assembly component includes a snap-fit ​​post, a limiting circular plate is fixedly connected to the right side of the snap-fit ​​post, a spring is fixedly connected to the right side of the limiting circular plate, a sliding rod is fixedly connected above the limiting circular plate, and a handle is fixedly connected above the sliding rod.

[0007] Preferably, a lower fixing seat assembly is slidably connected to the outer wall of the snap-fit ​​post. The lower fixing seat assembly includes a lower fixing plate. Several lower semi-circular grooves are opened on the upper part of the lower fixing plate. A fixing block is fixedly connected to the right side of the lower fixing plate. A T-shaped circular groove is opened on the left side of the fixing block. A square hole is opened on the upper part of the inner wall of the T-shaped circular groove. The inner wall of the T-shaped circular groove is slidably connected to the outer wall of the snap-fit ​​post and the limiting circular plate. The right side of the inner wall of the T-shaped circular groove is fixedly connected to the other end of the spring. The inner wall of the square hole is slidably connected to the outer wall of the sliding rod.

[0008] Preferably, the lower fixing plate is rotatably connected to the left side of the upper fixing seat assembly, the upper fixing seat assembly includes an upper fixing plate, the lower part of the upper fixing plate has a plurality of upper semi-circular grooves corresponding to a plurality of lower semi-circular grooves, the right side of the upper fixing plate has a circular insertion groove, the left side of the upper fixing plate is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected to the upper left of the lower fixing plate, and the inner wall of the circular insertion groove is slidably connected to the outer wall of the snap-fit ​​post.

[0009] Preferably, the inner walls of the upper and lower semicircular grooves are provided with uniform coating tubes, each uniform coating tube comprising a cylinder, a T-shaped cylinder fixedly connected to the rear of the inner wall of the cylinder, a uniform coating hole being opened in the middle of the front of the T-shaped cylinder, and the outer wall of the T-shaped cylinder being detachably clamped to the inner walls of the lower and upper semicircular grooves.

[0010] Preferably, a painting mechanism is fixedly connected below the lower fixed plate. The painting mechanism includes a painting chamber. A row of several painting heads is arranged at the front position above the painting chamber. A painting groove is opened above the painting head. A discharge port is opened in the middle of the lower part of the inner wall of the painting groove. The position above the rear side of the painting chamber is fixedly connected to the lower part of the lower fixed plate.

[0011] Preferably, a workbench is fixedly connected below the paint coating chamber.

[0012] Preferably, a first curing oven is fixedly connected to the rear side above the workbench. The first curing oven includes a second curing oven. The second curing oven has several circular holes at the front and rear, corresponding to several uniform coating holes. The circular holes at the front are electromagnetic wire inlets, and the circular holes at the rear are electromagnetic wire outlets.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The electromagnetic wire coating and curing production line of this utility model allows for quick replacement of the coating tube by grasping the handle and pulling it to the right, causing the sliding rod to slide between the limiting circular plate and the square hole and T-shaped groove.

The coating tube can then be removed from the lower semi-circular groove to complete the disassembly. During installation, the coating tube to be replaced is placed in the lower semi-circular groove, and the handle is pulled to place the locking post in the T-shaped groove. The rotation of the rotating shaft and the lower fixing plate rotates the upper fixing plate to the corresponding position of the circular insertion groove and the T-shaped groove. The handle is then released, and the spring pushes the limiting circular plate through its elastic force, causing the locking post to slide into the circular insertion groove for fixation, thus completing the installation. The design of the disassembly and assembly components allows for quick replacement of the coating tube, reducing the replacement time of a single coating tube to a few seconds and significantly reducing downtime losses caused by replacement.

[0015] 2. The coating and curing production line for electromagnetic wire described in this utility model addresses the issue that traditional coating devices have a strong correlation between the coating tube and the equipment body. If it is necessary to adapt to various wire specifications, such as electromagnetic wires with diameters of 0.05-5mm, it is often necessary to replace the entire coating module, including the coating tube, positioning frame, and paint guide structure. This not only results in high costs and a large number of spare modules, but also in complex debugging, requiring recalibration of the coaxiality between the wire center and the coating tube. The design of the disassembly and assembly components, as well as the lower and upper fixing components, allows the same coating device to be compatible with coating tubes of different apertures. Only the tube body needs to be replaced, without adjusting other structures, enabling flexible switching of multiple wire specifications and reducing equipment investment costs.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 4 As shown in the embodiment of this utility model, a coating and curing production line for electromagnetic wire includes a lower fixing seat assembly 2. The lower fixing seat assembly 2 is provided with a disassembly and assembly assembly 1. The disassembly and assembly assembly 1 includes a snap-fit ​​post 11. A limiting circular plate 12 is fixedly connected to the right side of the snap-fit ​​post 11. A spring 13 is fixedly connected to the right side of the limiting circular plate 12. A sliding rod 14 is fixedly connected above the limiting circular plate 12. A handle 15 is fixedly connected above the sliding rod 14. The lower fixing seat assembly 2 is slidably connected to the outer wall of the snap-fit ​​post 11. The lower fixing seat assembly 2 includes a lower fixing plate 21. A plurality of lower semi-circular grooves 22 are opened on the upper part of the lower fixing plate 21. A fixing block 23 is fixedly connected to the right side of the lower fixing plate 21. A T-shaped circular groove 24 is opened on the left side of the fixing block 23. A square hole 25 is provided on the upper part of the inner wall of the groove 24. The inner wall of the T-shaped circular groove 24 is slidably connected to the outer wall of the snap-fit ​​post 11 and the limiting circular plate 12. The right side of the inner wall of the T-shaped circular groove 24 is fixedly connected to the other end of the spring 13. The inner wall of the square hole 25 is slidably connected to the outer wall of the sliding rod 14. The upper fixed seat assembly 3 is rotatably connected to the left side of the lower fixed plate 21. The upper fixed seat assembly 3 includes an upper fixed plate 31. Several upper semi-circular grooves 33 corresponding to several lower semi-circular grooves 22 are provided below the upper fixed plate 31. A circular insertion groove 34 is provided on the right side of the upper fixed plate 31. A rotating shaft 32 is fixedly connected to the left side of the upper fixed plate 31. The rotating shaft 32 is rotatably connected to the upper left of the lower fixed plate 21. The inner wall of the circular insertion groove 34 is slidably connected to the outer wall of the snap-fit ​​post 11.

[0026] The assembly and disassembly unit 1, along with the lower fixing unit 2 and the upper fixing unit 3, allows for quick disassembly of the uniform coating tube 4. During use, by grasping the handle 15 and pulling it to the right, the sliding rod 14 causes the limiting circular plate 12 to slide against the square hole 25 and the T-shaped circular groove 24. The locking post 11 slides against the T-shaped circular groove 24 and the circular insertion groove 34, then disengages from the circular insertion groove 34. Next, grasp the upper fixing plate 31 and rotate it to rotate the rotating shaft 32 against the lower fixing plate 21. Finally, remove the uniform coating tube 4 from the lower semi-circular groove 22 to complete disassembly. During installation, insert the uniform coating tube 4 to be replaced into the lower semi-circular groove 22. In slot 22, pull handle 15 to place snap-fit ​​post 11 in T-shaped circular slot 24. Rotate upper fixing plate 31 to the corresponding position of circular insertion slot 34 and T-shaped circular slot 24 by rotating shaft 32 and lower fixing plate 21. Then release handle 15 to allow spring 13 to push limit plate 12 through elastic force, so that snap-fit ​​post 11 slides into circular insertion slot 34 for fixing, thus completing the installation. The design of disassembly and assembly component 1 allows the uniform coating tube 4 to be replaced quickly, reducing the replacement time of a single uniform coating tube to a few seconds, greatly reducing downtime losses caused by replacement.

[0027] Traditional uniform coating devices have a strong correlation between the uniform coating tube and the equipment body. If it is necessary to adapt to various wire specifications, such as electromagnetic wire with a diameter of 0.05-5mm, it is often necessary to replace the entire coating module, including the uniform coating tube, positioning frame, and paint guide structure. This is not only costly and requires a large number of spare modules, but also complicated to debug, requiring recalibration of the coaxiality between the wire center and the uniform coating tube. The design of the disassembly and assembly component 1, the lower fixing seat component 2, and the upper fixing seat component 3 allows the same coating device to be compatible with uniform coating tubes of different apertures. Only the tube body needs to be replaced, without adjusting other structures, which can achieve flexible switching of multiple wire specifications and reduce equipment investment costs.

[0028] like Figures 5 to 6 As shown, a uniform coating tube 4 is provided on the inner wall of the upper semi-circular groove 33 and the lower semi-circular groove 22. The uniform coating tube 4 includes a cylinder 41. A T-shaped cylinder 42 is fixedly connected to the rear of the inner wall of the cylinder 41. A uniform coating hole 43 is opened in the middle of the front of the T-shaped cylinder 42. The outer wall of the T-shaped cylinder 42 is detachably clamped to the inner wall of the lower semi-circular groove 22 and the upper semi-circular groove 33. A painting mechanism 5 is fixedly connected below the lower fixed plate 21. The painting mechanism 5 includes a paint tank 51. A row of several paint heads 52 is arranged at the front position above the paint tank 51. A coating tank 53 is provided above 52, and a discharge port 54 is provided in the lower middle part of the inner wall of the coating tank 53. The position of the coating chamber 51 above the rear side is fixedly connected to the lower fixed plate 21. A workbench 6 is fixedly connected below the coating chamber 51. A first curing oven 7 is fixedly connected above the rear side of the workbench 6. The first curing oven 7 includes a second curing oven 71. The second curing oven 71 has several round holes 72 corresponding to several uniform coating holes 43 at the front and rear. The front round hole 72 is the electromagnetic wire inlet, and the rear round hole 72 is the electromagnetic wire outlet.

[0029] Curing oven No. 2 (71) is existing technology. Its working principle involves using a precisely controlled temperature environment to heat the electromagnetic wire coated with insulating varnish in stages, causing the varnish layer to undergo a transformation from solvent evaporation to chemical curing and then to stable molding, ultimately forming a solid insulating film that meets performance requirements. Its core principle is utilizing heat energy to drive physical changes such as solvent evaporation and chemical changes such as molecular cross-linking, which will not be elaborated upon here.

[0030] The painting head 52 is existing technology. It is connected to the painting tank 51 through a pipe. The insulating varnish is continuously injected into the painting tank 53 above the painting head 52 by gravity or a low-pressure pump at 0.1-0.3MPa to ensure that the inner hole of the mold is always full of varnish. This will not be elaborated on further here.

[0031] Working principle: The disassembly assembly 1, together with the lower fixing seat assembly 2 and the upper fixing seat assembly 3, allows for quick disassembly of the uniform coating tube 4. During use, by grasping the handle 15 and pulling it to the right, the sliding rod 14 causes the limiting circular plate 12 to slide against the square hole 25 and the T-shaped circular groove 24. After the locking post 11 slides against the T-shaped circular groove 24 and the circular insertion groove 34, it disengages from the circular insertion groove 34. Then, by grasping the upper fixing plate 31 and rotating it, the rotating shaft 32 and the lower fixing plate 21 rotate. The uniform coating tube 4 can then be removed from the lower semi-circular groove 22 to complete disassembly. During installation, the uniform coating tube 4 to be replaced is placed into the lower semi-circular groove 22. In the circular groove 22, pull the handle 15 to place the snap-fit ​​post 11 in the T-shaped circular groove 24. By rotating the rotating shaft 32 and the lower fixing plate 21, rotate the upper fixing plate 31 to the corresponding position of the circular insertion groove 34 and the T-shaped circular groove 24. Then release the handle 15 so that the spring 13 pushes the limiting circular plate 12 through the elastic force, thereby allowing the snap-fit ​​post 11 to slide into the circular insertion groove 34 for fixing, thus completing the installation. The design of the disassembly and assembly component 1 allows the uniform coating tube 4 to be quickly replaced, reducing the replacement time of a single uniform coating tube to a few seconds, greatly reducing downtime losses caused by changing the type.

[0032] Traditional uniform coating devices have a strong correlation between the uniform coating tube and the equipment body. If it is necessary to adapt to various wire specifications, such as electromagnetic wire with a diameter of 0.05-5mm, it is often necessary to replace the entire coating module, including the uniform coating tube, positioning frame, and paint guide structure. This is not only costly and requires a large number of spare modules, but also complicated to debug, requiring recalibration of the coaxiality between the wire center and the uniform coating tube. The design of the disassembly and assembly component 1, the lower fixing seat component 2, and the upper fixing seat component 3 allows the same coating device to be compatible with uniform coating tubes of different apertures. Only the tube body needs to be replaced, without adjusting other structures, which can achieve flexible switching of multiple wire specifications and reduce equipment investment costs.
