Description

Technical Field

[0001] This invention relates to the field of enameled wire production technology, and in particular to a rapid coating device for enameled wire based on ultraviolet light curing. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then undergoes multiple coatings and baking processes. The conductor is typically made of metals with good electrical conductivity, such as copper or aluminum. Enameled wire is widely used in motors, electrical appliances, instruments, telecommunications equipment, and household appliances as the conductor for windings or coils. Its performance directly affects the operating performance and service life of related equipment, making it an indispensable material in the electronics and electrical fields.

[0003] Enamelled wire coating equipment is used in the production of enamelled wire to coat conductors (such as copper wire, aluminum wire, etc.) with insulating varnish. However, many existing coating equipment use fixed-size coating molds, which can only accommodate wires of one diameter. Once the wire size changes, the gap between the mold and the wire cannot be guaranteed to be appropriate. Either the gap is too large, resulting in uneven coating of the insulating varnish, with missed areas or an excessively thin varnish layer; or the gap is too small, causing excessive resistance when the wire passes through the mold, or even getting stuck, affecting production efficiency and product quality. Therefore, to solve the above problems, a rapid enamelled wire coating device based on ultraviolet light curing is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid coating device for enameled wire based on ultraviolet light curing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rapid coating device for enameled wire based on ultraviolet light curing includes a support frame, on which a wire feeding frame and a wire take-up mechanism are mounted. A movable varnish tube is slidably mounted on the upper part of the support frame. An adjusting curing coating mechanism is mounted on the varnish tube, which includes a lifting ring plate with multiple scrapers rotatably arranged at equal intervals around its circumference. A fixing ring is located at the top of the varnish tube, with multiple coating plates rotatably arranged at equal intervals around its circumference. The coating plates and scrapers can move synchronously. Guide plates are symmetrically mounted on the varnish tube, with multiple equidistant ultraviolet lamps slidably mounted on the guide plates. The coating plates and scrapers are used to uniformly coat conductors of different sizes with insulating varnish, and the ultraviolet lamps are used for ultraviolet curing of conductors of different sizes. The take-up mechanism is used for uniform take-up and tension adjustment of conductors of different sizes.

[0006] The above technical solution further includes: The take-up mechanism includes a take-up frame fixedly installed on the top of the support, a take-up motor installed on the side of the take-up frame, a take-up shaft rotatably connected to the take-up frame at the output end of the take-up motor, a take-up reel installed on the take-up shaft, and a drive sprocket fixedly connected to one end of the take-up shaft extending to the outside of the support.

A cable guide head is slidably connected to the reciprocating screw on the guide rod. A driven sprocket is fixedly connected to one end of the reciprocating screw extending to the outside of the take-up frame. A chain is sleeved between the driven sprocket and the chain. A tensioning coil is rotatably connected inside the take-up frame. A tension motor is installed on the side of the take-up frame near the chain. The output end of the tension motor is fixedly connected to the tensioning coil.

[0008] The bracket is equipped with a height adjustment mechanism for raising and lowering the paint cylinder. The height adjustment mechanism includes a lifting motor installed at the bottom of the bracket, and a lifting screw that is rotatably connected to the bracket is installed at the output end of the lifting motor. Guide rails are symmetrically fixedly connected to the top of the bracket.

[0009] One of the guide rails is rotatably connected to the lifting screw, and a slide rod is fixedly connected to the inner side of the other guide rail. The paint cylinder slides relative to the slide rod. The paint cylinder is threadedly connected to the lifting screw. A mounting plate is fixedly connected to the side of the paint cylinder, and a drying oven is mounted on the mounting plate.

[0010] A support roller is installed on the paint cylinder, a top plate is installed on the top of the paint cylinder, a spring damping rod is fixedly connected to the bottom of the top plate, and a pressure roller is fixedly connected to the bottom of the spring damping rod.

[0011] The adjustment curing coating mechanism also includes an adjustment motor installed at the bottom of the top plate, and an adjustment gear and a cylindrical gear are installed on the output shaft of the adjustment motor.

[0012] Multiple rotating rods are rotatably connected to the lifting ring disc, and the rotating rods are fixedly connected to the scraper. A connecting rod is fixedly connected between the coating plate and the scraper.

[0015] The present invention has the following beneficial effects: In this invention, when dealing with conductors of different sizes, the contact angle and pressure between the coating plate and the conductor can be changed by adjusting the movement state of the coating plate and the scraper. This design can meet the needs of conductors of different sizes, greatly improving the versatility and production flexibility of the device, and reducing production costs and equipment maintenance difficulty.

[0016] In this invention, multiple equidistant ultraviolet lamps are slidably mounted on guide plates symmetrically installed on the paint canister. When coating conductors of different sizes, the position and spacing of the ultraviolet lamps can be adjusted according to the diameter of the conductor. This adjustable ultraviolet lamp layout allows the device to adapt to the curing requirements of conductors of different sizes, further improving the versatility and production flexibility of the device.

[0019] 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.

[0020] Example like Figures 1-7 As shown, the present invention proposes a rapid coating device for enameled wire based on ultraviolet light curing, including a support 1, on which a wire feeding frame 3 and a wire take-up mechanism are mounted. A movable varnish cylinder 53 is slidably arranged on the upper part of the support 1. An adjusting curing coating mechanism is installed on the varnish cylinder 53. The adjusting curing coating mechanism includes a lifting ring plate 43. Multiple scrapers 42 are circumferentially rotatably arranged on the lifting ring plate 43. A fixing ring 48 is provided at the top of the varnish cylinder 53. Multiple coating plates 411 are circumferentially rotatably arranged on the fixing ring 48. The coating plates 411 and scrapers 42 can move synchronously. A guide plate 40 is symmetrically mounted on the varnish cylinder 53. Multiple ultraviolet lamps 461 that can move at equal distances are slidably arranged on the guide plate 40. The coating plates 411 and scrapers 42 are used to uniformly coat conductors of different sizes with insulating varnish. The ultraviolet lamps 461 are used for ultraviolet curing of conductors of different sizes. The take-up mechanism is used for uniform take-up and tension adjustment of conductors of different sizes; Furthermore, at the start of production, the conductor roll to be coated is placed on the pay-off frame 3. After the conductor is led out from the pay-off frame 3, it enters the coating area. The paint cylinder 53, which can move up and down on the upper part of the support 1, is filled with insulating varnish. When the conductor enters the paint cylinder 53, the adjusting curing coating mechanism begins to function. Multiple scrapers 42, which are circumferentially equidistantly arranged on the lifting ring 43, and multiple coating plates 411, which are circumferentially equidistantly arranged on the top fixing ring 48 of the paint cylinder 53, move synchronously and adaptively according to the size of the conductor. For example, if the conductor is thin, the coating plates 411 and scrapers 42 will rotate and adjust their angles to contact the conductor with a smaller contact area and appropriate pressure. The scraper 42 scrapes off excess insulating varnish, and the coating plates 411 evenly apply the insulating varnish to the conductor surface, ensuring that the insulating varnish is evenly distributed and of appropriate thickness on the conductor surface. If the conductor is thick, the coating plates 411 and scrapers 42 will correspondingly increase the contact area and adjust the pressure to ensure that the insulating varnish can fully and evenly cover the entire conductor surface, thereby achieving the purpose of uniformly coating insulating varnish on conductors of different sizes. After the insulating varnish is applied, the conductor enters the curing area.

[0021] Furthermore, depending on the conductor size, the UV lamp 461 slides on the guide plate 40 to adjust its position and spacing. For thinner conductors, the UV lamp 461 moves closer to the conductor and reduces the spacing, allowing the UV light to be more concentrated on the coated area, quickly triggering a chemical reaction in the photoinitiator in the insulating varnish and achieving rapid curing. For thicker conductors, the UV lamp 461 appropriately increases the spacing to ensure that the entire coating layer receives uniform irradiation from the UV lamp 461, guaranteeing the curing effect.

[0022] Furthermore, simultaneously, the take-up mechanism begins operation, capable of uniformly taking up the wire and adjusting the tension according to the characteristics of conductors of different sizes. For example, for thinner conductors, the take-up mechanism reduces the take-up speed and braking force to prevent the conductor from breaking due to excessive tension; for thicker conductors, the take-up mechanism appropriately increases the take-up speed and braking force to ensure that the conductor maintains stable tension during the take-up process, preventing the wire from slack from affecting the coating and curing effect, ultimately completing the rapid coating and curing production of the enameled wire.

[0023] The take-up mechanism includes a take-up frame 2 fixedly installed on the top of the bracket 1, a take-up motor 21 installed on the side of the take-up frame 2, a take-up shaft 210 rotatably connected to the take-up frame 2 at the output end of the take-up motor 21, a take-up reel 22 installed on the take-up shaft 210, and a drive sprocket 29 fixedly connected to one end of the take-up shaft 210 extending to the outside of the bracket 1. A reciprocating screw 20 is rotatably connected to the inner side of the take-up frame 2. A guide rod 24 is fixedly connected to the take-up frame 2 on the bottom side of the reciprocating screw 20. A cable guide head 25 is slidably connected to the reciprocating screw 20. A driven sprocket 28 is fixedly connected to one end of the reciprocating screw 20 extending to the outside of the take-up frame 2. A chain 27 is sleeved between the driven sprocket 28 and the chain 27. A tightening coil 23 is rotatably connected inside the take-up frame 2. A tension motor 26 is installed on the side of the take-up frame 2 near the chain 27. The output end of the tension motor 26 is fixedly connected to the tightening coil 23. Furthermore, the take-up mechanism uses an internal tension sensor to monitor the conductor tension in real time and feeds the data back to the control system. The control system then precisely adjusts the take-up speed and braking force of the take-up mechanism based on preset tension parameters corresponding to different conductor sizes.

[0024] Furthermore, when the enameled wire coating is completed and the winding process begins, the winding motor 21 starts, and its output drives the winding shaft 210 to rotate on the winding frame 2. Since the winding reel 22 is mounted on the winding shaft 210, the rotation of the winding shaft 210 will drive the winding reel 22 to rotate synchronously, winding the coated and cured enameled wire onto the winding reel 22 to achieve the winding function. At the same time, the drive sprocket 29, which is fixedly connected to one end of the winding shaft 210 extending to the outside of the bracket 1, will rotate together with the winding shaft 210. The drive sprocket 29 is sleeved with the driven sprocket 28 through the chain 27, thereby driving the driven sprocket 28 to rotate. The driven sprocket 28 is fixedly connected to one end of the reciprocating screw 20 extending to the outside of the winding frame 2, so the rotation of the driven sprocket 28 will drive the reciprocating screw 20 to rotate inside the winding frame 2. When the reciprocating screw 20 rotates, the wire guide head 25, which is threaded to it, cannot rotate with the reciprocating screw 20 due to the sliding restriction of the guide rod 24. It can only make reciprocating linear motion along the guide rod 24. When the enameled wire is wound onto the take-up reel 22, it will first pass through the wire guide head 25. The reciprocating motion of the wire guide head 25 ensures that the enameled wire is evenly arranged on the take-up reel 22, avoiding the accumulation or uneven winding of the enameled wire on the take-up reel 22.

[0025] Furthermore, during the winding process, the tension motor 26 plays a crucial role in ensuring stable tension when winding enameled wires of different sizes. The output end of the tension motor 26 is fixedly connected to the winding coil 23. When the tension motor 26 starts, it drives the winding coil 23 to rotate within the winding frame 2. The enameled wire is wound in an S-shape around the winding coil 23, applying a certain tension to the wire and thus regulating the tension. For example, if excessive tension is detected, the tension motor 26 adjusts the rotation direction or speed of the winding coil 23 to reduce the tension on the wire; conversely, if insufficient tension is detected, the tension motor 26 increases the tension of the winding coil 23 on the wire, thereby achieving precise tension adjustment for winding enameled wires of different sizes and ensuring a smooth winding process.

[0026] The bracket 1 is equipped with a height adjustment mechanism for raising and lowering the paint can 53. The height adjustment mechanism includes a lifting motor 50 installed at the bottom of the bracket 1, a lifting screw 51 rotatably connected to the bracket 1 at the output end of the lifting motor 50, and guide rails 5 symmetrically fixedly connected to the top of the bracket 1. One guide rail 5 is rotatably connected to the lifting screw 51, and the inner side of the other guide rail 5 is fixedly connected to the slide rod 52. The paint cylinder 53 slides relative to the slide rod 52. The paint cylinder 53 is threadedly connected to the lifting screw 51. The side of the paint cylinder 53 is fixedly connected to the mounting plate 56, and the drying oven 6 is installed on the mounting plate 56. Furthermore, when it is necessary to add insulating varnish to the paint cylinder 53, the lifting motor 50 installed at the bottom of the bracket 1 is activated. Its output end drives the lifting screw 51 to rotate on the bracket 1. When the lifting screw 51 rotates, the paint cylinder 53, due to the sliding restriction of the slide rod 52, cannot rotate with the lifting screw 51, but instead moves vertically up and down along the axis of the slide rod 52. In this way, the height of the paint cylinder 53 can be precisely adjusted. Furthermore, the function of the drying oven 6 is to perform preliminary drying treatment on the enameled wire after it has been coated with insulating varnish. After the enameled wire comes out of the varnish canister 53 after being coated with insulating varnish, it will pass through the drying oven 6. The drying oven 6 uses heating and other methods to evaporate some of the solvent in the insulating varnish, thereby accelerating the drying process of the insulating varnish and improving the coating quality and production efficiency.

[0027] A support roller 55 is installed on the paint cylinder 53, a top plate 4 is installed on the top of the paint cylinder 53, a spring damping rod 57 is fixedly connected to the bottom of the top plate 4, and a pressure roller 54 is fixedly connected to the bottom of the spring damping rod 57. Furthermore, during the enameled wire coating process, the enameled wire is mounted on a support roller 55. The support roller 55 supports the enameled wire, providing a stable running path so that the wire can smoothly pass through the enamel cylinder 53. The wire passes through the bottom of the enamel cylinder 53. When the wire enters below the pressure roller 54, the wire's inherent tension and elasticity exert an upward force on the pressure roller 54. The spring damping rod 57, with its elasticity and damping characteristics, applies a downward reaction force to the pressure roller 54. The magnitude of this reaction force can be adjusted by the spring damping rod 57's elastic coefficient and damping characteristics. Under the action of the spring damping rod 57, the pressure roller 54 presses the enameled wire with appropriate pressure. This pressure helps ensure better contact between the enameled wire and the insulating varnish inside the enamel cylinder 53, ensuring that the insulating varnish is evenly coated on the surface of the wire.

[0028] The adjustment curing coating mechanism also includes an adjustment motor 44 installed at the bottom of the top plate 4, and an adjustment gear 415 and a cylindrical gear 416 are installed on the output shaft of the adjustment motor 44; Multiple rotating rods 41 are rotatably connected to the lifting ring disc 43. The rotating rods 41 are fixedly connected to the scraper 42. A connecting rod 413 is fixedly connected between the coating plate 411 and the scraper 42. The fixed ring 48 is fixedly connected to the top plate 4. Multiple drive shafts 410 are rotatably connected to the fixed ring 48. Driven gears 412 and coating plates 411 are fixedly connected to the drive shafts 410. A drive gear ring 49 is rotatably connected to the side of the fixed ring 48 near the coating plate 411. The drive gear ring 49 meshes with the multiple driven gears 412. The drive gear ring 49 meshes with the adjusting gear 415. A bearing seat 414 that is rotatably connected to the output shaft of the adjusting motor 44 is installed on the fixed ring 48. A drive disk 45 is rotatably connected between two guide disks 40. Multiple guide grooves 401 are circumferentially opened on the two guide disks 40. Multiple adjusting gears 415 are circumferentially opened on the drive disk 45. A sliding frame 46 is slidably arranged together with the guide grooves 401 and the drive grooves 451. Multiple ultraviolet lamps 461 are installed at the bottom of the sliding frame 46. A sector rack 47 is installed on the drive disk 45. The column gear 416 and the sector rack 47 mesh with each other. Furthermore, during the enameled wire coating process, when it is necessary to adjust the positions of the coating plate 411 and the scraper 42, as well as the spacing of the UV lamps 461, according to different conductor sizes, the adjusting motor 44 is activated. The output shaft of the adjusting motor 44 is equipped with an adjusting gear 415 and a cylindrical gear 416. On one hand, the adjusting motor 44 drives the adjusting gear 415 to rotate, which in turn drives the driving gear ring 49 to rotate on the fixed ring 48. Since multiple drive shafts 410 rotatably connected to the fixed ring 48 are fixedly connected to driven gears 412 and the coating plate 411, and the driving gear ring 49 meshes with the multiple driven gears 412, the rotation of the driving gear ring 49 drives the multiple driven gears 412 to rotate synchronously, thereby causing the multiple drive shafts 410 to rotate, which in turn drives the coating plate 411 to rotate. Meanwhile, multiple rotating rods 41 rotatably connected to the lifting ring disc 43 are fixedly connected to the scraper 42. A connecting rod 413 is fixedly connected between the coating plate 411 and the scraper 42. When the coating plate 411 rotates, it will drive the scraper 42 to rotate synchronously through the connecting rod 413. In this way, the coating plate 411 and the scraper 42 can move synchronously according to conductors of different sizes, and contact the conductor with a suitable angle and contact area to ensure that the insulating varnish can completely cover the conductor.

[0029] Furthermore, the output shaft of the adjusting motor 44 also drives the cylindrical gear 416 to move. When the adjusting motor 44 drives the cylindrical gear 416 to move, the meshing action between the cylindrical gear 416 and the sector rack 47 will cause the sector rack 47 to drive the drive disk 45 to rotate between the two guide disks 40. During the rotation of the drive disk 45, the sliding frame 46 will slide within the guide groove 401 and the drive groove 451 due to the sliding restriction and guiding effect of the guide groove 401 and the drive groove 451. This will drive the multiple ultraviolet lamps 461 installed at the bottom of the sliding frame 46 to move equidistantly on the guide disk 40. The position and spacing of the ultraviolet lamps 461 are adjusted according to the conductors of different sizes. For example, for thinner conductors, the ultraviolet lamps 461 will be closer to the conductor and the spacing will be reduced so that the ultraviolet rays are more concentrated on the coating area, thus accelerating the curing speed. For thicker conductors, the spacing of the ultraviolet lamps 461 will be appropriately increased to ensure that the entire coating layer can be uniformly irradiated by ultraviolet rays, thereby achieving rapid curing of the insulating varnish of conductors of different sizes and ensuring the coating quality.

[0030] In this embodiment, during the coating process, the conductor enters the paint cylinder 53, and the coating plate 411 is rotated by the adjustment motor 44. Multiple coating plates 411 cooperate with each other to form a circle in the central area, and the size of the circle is adjustable. At the same time, the coating plate 411 drives the scraper 42 to rotate synchronously through the connecting rod 413. The two move synchronously according to the conductor size to contact the conductor at a suitable angle and contact area to ensure uniform coating of insulating paint. After coating, the conductor enters the curing area. The motor 44 drives the sliding frame 46 to move multiple UV lamps 461 at the bottom at equal intervals on the guide plate 40. The position and spacing of the UV lamps 461 are adjusted according to the conductor size to achieve rapid curing.

[0031] The take-up mechanism operates by driving the take-up motor 21 to make the wire guide head 25 reciprocate linearly along the guide rod 24, so that the enameled wire is evenly arranged on the take-up reel 22. The take-up mechanism monitors the conductor tension in real time through a tension sensor and feeds it back to the control system. The control system adjusts the tension by driving the tension winding 23 to rotate through the tension motor 26 according to preset parameters.

[0032] 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.
