Description

Technical Field

[0001] This invention belongs to the field of copper wire processing technology, specifically relating to a copper wire side thickening coating equipment. Background Technology

[0002] Copper wire, as a fundamental component in fields such as power transmission and electronic equipment manufacturing, directly affects the safety and stability of the entire circuit system due to its insulation performance. Coils are typically made of copper wire wound with an insulating enamel coating to prevent conductivity. However, when this insulating enamel coating is "broken down" due to some reason (such as excessive voltage, mechanical damage, material defects, or environmental stress), it loses its insulating function. Once the enamel coating is damaged, the metal part of the coil may accidentally conduct through the leads or surrounding powder (which may be magnetic powder or other filler materials) to the pins (the metal feet that connect the product to the external circuit). This unintended conduction creates a low-resistance path, allowing current to bypass the normal path and flow directly from the coil to the pins, causing a short circuit. Ultimately, this leads to product malfunction. The root cause of the product failure is the damage to the coil's insulation layer, leading to a short circuit between the internal conductors and the pins, which in turn causes the entire circuit to malfunction.

[0003] When a product fails on the client side (i.e., the user end), the most critical issue is a short circuit between the outer side of the coil and the pins inside the product. To improve the insulation of copper wires, the industry commonly uses a process of coating the surface of the copper wire with insulating varnish. This insulating varnish layer isolates the copper wire from conductive contact with the outside world, preventing faults such as short circuits and leakage.

[0004] In traditional copper wire coating processes, the quality of the insulating varnish coating directly affects the insulation performance and service life of the enameled wire. Currently, most common enameled wire coating equipment uses overall immersion or full-area spraying methods. Although these methods can form an insulating layer on the surface of the copper wire, for some scenarios with special requirements, such as enhancing the insulation performance of the copper wire's sides to prevent short circuits between the sides and other components, existing equipment cannot accurately achieve thicker varnish coating on the sides of the copper wire. To meet the side insulation requirements, the overall varnish layer thickness must be increased. This not only results in a significant waste of insulating varnish material but also increases the overall diameter of the copper wire, occupying more winding space and reducing the power density of the equipment.

[0005] For example, Chinese invention patent document CN119296883A discloses a high-speed vertical fully automatic painting device. This high-speed vertical fully automatic painting device includes a painting box, a drying box fixedly installed on the upper surface of the painting box, a cooling box fixedly installed on the top of the drying box, a paint box fixedly connected to the inner side wall of the painting box, a sloped surface on one side of the paint box, and a row of paint grooves opened on the sloped surface of the paint box. A connecting plate is fixedly connected to the inner side wall of the painting box, and a row of empty grooves is opened on the surface of the connecting plate. A painting mold is installed inside each empty groove. The painting mold matches the paint groove. Through the setting of the painting mold, spring assembly and cooling box, this device can make the concentricity of the enameled wire better, the painting more uniform, avoid the appearance of paint nodules and defects on the surface of the wire harness, and at the same time, it can quickly cool down the wire harness.

[0006] For example, a Chinese invention patent document with publication number CN114551011A discloses an automated coating device for enameled copper wire, including a coating unit and a drying unit. The drying unit is fixedly installed at the lower end of the coating unit. Through the cooperation of the coating unit and the drying unit, the surface of the copper wire is polished and cleaned, and finally coated. After multiple coating processes, the surface coating thickness of the enameled copper wire is ensured to be uniform. At the same time, excess paint on the surface of the copper wire during the coating process is collected to prevent the paint from solidifying due to contact with the drying lamp during the flow and collection process, which would affect the utilization rate of the paint. The whole process does not require multiple equipment to be arranged for processing or a large number of staff to observe, thus reducing the processing cost of enameled copper wire.

[0007] Existing technologies often involve coating the entire coil, making it impossible to coat specific areas. Furthermore, when coating specific areas, it is difficult to control the effective coating range, which can easily lead to uneven coating edges. Therefore, the industry currently needs a specialized device that can thicken the coating on the sides of the coil to address the shortcomings of traditional coating processes in special application scenarios, improve the insulation performance and service life of the coil, reduce material waste, and increase production efficiency. Summary of the Invention

[0008] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide a copper wire side coating thickening device.

[0009] This invention provides the following technical solution: A copper wire side coating thickening device includes clamps and nozzles. Two clamps are respectively mounted on side plates, which are symmetrically installed. Clamping jaws are evenly distributed within each clamp. When the jaws move in a converging manner towards the center, they fix the workpiece; when they move in a spreading manner, they release the workpiece. The contact surface between the jaws and the workpiece is a concave arc surface. A central rod is movably installed between the two side plates. A liquid-containing body is slidably mounted on the central rod. The liquid-containing body has a region for storing the coating. The nozzles are mounted... On the liquid-containing body and connected to the area storing paint, the two side plates are also respectively equipped with two upper screws and two lower screws. The upper screws are located above the lower screws. An upper stop block is installed on the upper screw, and a lower stop block is installed on the lower screw. The bottom end face of the upper stop block and the top end face of the lower stop block are inclined surfaces, and the bottom of the upper stop block and the top of the lower stop block are respectively provided with an upper arc edge and a lower arc edge. The extended surface of the right end face of the upper stop block is located on one side of the workpiece, and the extended surface of the right end face of the lower stop block is located to the left of the center line of the workpiece.

[0010] To prevent paint from splattering during painting and to ensure that the paint is sprayed accurately and evenly onto the coil.

[0011] As a further technical solution, a heating body is installed inside the upper baffle.

[0012] As a further technical solution, an upper exhaust pipe is installed on the right end face of the upper stop block, and a lower exhaust pipe is installed on the bottom end face of the upper stop block. The lower exhaust pipe is inclined toward the workpiece processing surface, and the upper exhaust pipe is inclined toward the liquid container.

[0013] As a further technical solution, the upper baffle is provided with an upper heat storage chamber and a lower heat storage chamber. The upper heat storage chamber is located diagonally above the heating body, and the lower heat storage chamber is located below the heating body. An outer frame is installed on the outside of the heating body. A heat-conducting pipe is connected between the outer frame and the upper heat storage chamber. One end of the upper exhaust pipe is located inside the upper heat storage chamber, and the other end extends to the outside of the upper baffle. A heat-conducting pipe is connected between the outer frame and the lower heat storage chamber. One end of the lower exhaust pipe is located inside the lower heat storage chamber, and the other end extends to the outside of the upper baffle. A vacuum pump is installed on both the heat-conducting pipe and the heat-conducting pipe.

[0014] As a further technical solution, the structure inside the lower stop block is the same as the structure inside the upper stop block, and the structures inside the lower stop block and the structures inside the upper stop block are symmetrically distributed vertically.

[0015] The symmetrical structure allows the gas to act on the coil paint surface to the maximum extent, resulting in a fast paint drying speed and achieving rapid drying of the surrounding paint.

[0016] As a further technical solution, the liquid container has a main concave hole, the nozzle is located in the main concave hole, and multiple ventilation openings are evenly provided on both sides of the main concave hole.

[0017] As a further technical solution, the upper screw is threadedly connected to an upper sliding sleeve, and a connecting rod is installed between the two upper sliding sleeves. The connecting rod passes through the top of the upper stop block. The lower screw is threadedly connected to a lower sliding sleeve, and a bent rod is installed between the two lower sliding sleeves. The horizontal part of the bent rod passes through the bottom of the lower stop block.

[0018] As a further technical solution, a base plate is installed at the bottom of the two side plates, and a base plate groove is opened on the base plate. A base is installed between the clamp and the side plate. The clamp and the base are fixedly connected, and the base and the side plate are rotatably connected. One end of the base extends to the rear end of the side plate and is fitted with a drive wheel. Connecting parts are also provided on the clamp. An outer circular rotating ring is also installed on the inner side of the side plate. Inner circular rotating rings are symmetrically installed on the outer circular rotating ring. The intermediate rod is fixedly installed on the inner circular rotating ring.

[0019] As a further technical solution, plates are symmetrically installed in the bottom plate groove, and a gap is left between the two symmetrically installed plates to form a flow channel. The top surface of the plates is a downward inclined surface.

[0020] As a further technical solution, a partition is installed in the bottom plate groove, and multiple drip holes are evenly opened on the partition.

[0021] The beneficial effects of this invention are: By installing a nozzle on one side of the coil to apply paint to specific areas of the coil, the thickness of the outer enamel coating is increased from the conventional 15μm to 25μm. This effectively reduces the risk of the coil breaking down during lamination, preventing short circuits caused by the formation of a circuit with the powder and leads. This solves product failure problems and improves product yield. Upper and lower baffles are installed above and below the coil, respectively. Paint outside the effective spray range falls onto these baffles, ensuring precise and even spraying of the paint onto the coil. Heating units are installed within the upper and lower baffles, maximizing the effect of heat on the painted areas of the coil, accelerating paint drying and improving painting efficiency.

[0024] like Figure 1 As shown, the present invention provides a copper wire side thickening coating device, including a clamping plate 1 and a nozzle 18. The coil is fixed by two opposing clamping plates. The device is also provided with a side plate 7. The two clamping plates 1 are respectively installed on the side plate 7. The two side plates 7 are installed symmetrically. The clamping plates 1 are evenly distributed with clamping claws 3. When multiple clamping claws 3 move towards the center in a converging manner, the workpiece is fixed. When multiple clamping claws 3 move in a spreading manner, the workpiece is released. In order to facilitate the contact between the clamping claws 3 and the coil, the contact surface between the clamping claws 3 and the workpiece is a concave arc surface 4. The thickness of the coil will not affect the stability of the clamping claws 3 in fixing the coil, so as to perform local thickening coating on the coil.

[0025] In order to allow for thicker coating of paint on specific areas of the coil, such as... Figure 1 As shown, a middle rod 15 is movably installed between the two side plates 7. A liquid container 17 is slidably installed on the middle rod 15. The liquid container 17 has an area for storing paint, and a nozzle 18 is installed on the liquid container 17 and connected to the area for storing paint. Paint is evenly sprayed onto the coil through the nozzle 18. In addition, the middle rod 15 is driven to rotate by an external force, so that the liquid container 17 rotates together with the middle rod 15. By rotating, the angle of the nozzle 18 is changed, so that different sides of the coil can be sprayed with paint.

[0026] A base 2 is installed between the clamping plate 1 and the side plate 7. The clamping plate 1 and the base 2 are fixedly connected, and the base 2 and the side plate 7 are rotatably connected. One end of the base 2 extends to the rear end of the side plate 7 and is fitted with a drive wheel 8. A connector 9 is also provided on the clamping plate 1. The connector 9 is used to facilitate the communication coupling between the base 2 and the whole machine control system, so that the clamping plate 1 can rotate with the base 2 and the processing surface of the coil can be rotated and adjusted.

[0027] In addition, such as Figure 1 and Figure 2 As shown, an outer circular rotating ring 13 is also installed on the inner side of the side plate 7. An inner circular rotating ring 14 is symmetrically installed on the outer circular rotating ring 13. The intermediate rod 15 is fixedly installed on the inner circular rotating ring 14. The position of the nozzle relative to the coil can be controlled by the outer circular rotating ring 13, that is, the position of the paint spraying can be adjusted according to the processing surface. The inner circular rotating ring 14 is controlled by the control system to realize the rotation of the intermediate rod 15, thereby adjusting the angle of the nozzle 18.

[0028] Example 1 To ensure precise painting of specific areas of the coil and avoid painting an excessively large area, such as... Figure 2 As shown, each of the two side plates 7 is also equipped with two upper screws 23 and two lower screws 38. The upper screws 23 and lower screws 38 are rotatably connected to the side plates 7. The upper screws 23 are threaded with upper sliding sleeves 20. A connecting rod 21 is installed between the two upper sliding sleeves 20. The connecting rod 21 passes through the top of the upper stop block 22. That is, when the upper screws 23 rotate, the upper sliding sleeves 20 move linearly with the connecting rod 21 and the upper stop block 22. The lower screws 38 are threaded with lower sliding sleeves 26. A bent rod 25 is installed between the two lower sliding sleeves 26. The horizontal part of the bent rod 25 passes through the bottom of the lower stop block 24. That is, when the lower screws 38 rotate, the lower sliding sleeves 26 move linearly. Moving linearly with the bending rod 25 and the lower stop 24, the upper screw 23 is positioned above the lower screw 38. The upper stop 22 is mounted on the upper screw 23, and the lower stop 24 is mounted on the lower screw 38. The bottom end face of the upper stop 22 and the top end face of the lower stop 24 are inclined surfaces. In the whole machine, the controller system ensures that the upper stop 22, the lower stop 24 and the nozzle 18 are in the same position. The center position of the upper stop 22 and the lower stop 24 and the center line of the nozzle 18 are on the same vertical plane. When the nozzle 18 sprays paint onto the coil, the paint outside the effective spray range falls onto the upper stop 22 and the lower stop 24, thereby ensuring that the paint can be sprayed accurately and evenly onto the coil.

[0029] like Figure 2 and Figure 3As shown, the right end face extension of the upper stop block 22 is located on one side of the workpiece, and the right end face extension of the lower stop block 24 is located slightly to the left of the workpiece centerline. The purpose is to make the blocking surface of the upper stop block 22 and the nozzle 18 close together, that is, the adjustment of the ineffective spraying range can fall on the blocking surface of the upper stop block 22. In addition, according to the design of the spray angle, in order to avoid the paint splashing below, the distance between the nozzle 18 and the lower stop block 24 is increased. Furthermore, the bottom of the upper stop block 22 and the top of the lower stop block 24 are respectively provided with an upper arc edge 27 and a lower arc edge 28. By setting the upper arc edge 27 and the lower arc edge 28, the resistance of the liquid sprayed by the nozzle 18 is reduced, and the paint splashing is further prevented.

[0030] Example 2 Based on the above embodiment one, in order to accelerate the drying of the varnish applied to the coil, therefore, as Figure 4 As shown, a heating body 36 is installed inside the upper baffle 22. The heating body 36 heats the upper baffle 22, causing the temperature near the upper baffle 22 to rise, thereby achieving rapid drying of the paint.

[0031] Furthermore, an upper exhaust pipe 31 is installed on the right end face of the upper stop block 22, and a lower exhaust pipe 32 is installed on the bottom end face of the upper stop block 22. The lower exhaust pipe 32 is inclined towards the workpiece processing surface, and the upper exhaust pipe 31 is inclined towards the liquid body 17. Through the action of airflow, the hot air is applied to the local painted side of the coil to the maximum extent, which further accelerates the drying of the paint and improves the painting efficiency.

[0032] Specifically, the upper baffle 22 is provided with an upper heat storage chamber 29 and a lower heat storage chamber 30. The upper heat storage chamber 29 is located diagonally above the heating body 36. One end of the upper exhaust pipe 31 is located inside the upper heat storage chamber 29, and the other end extends to the outside of the upper baffle 22. The high-temperature gas in the upper heat storage chamber 29 is concentratedly discharged through the upper exhaust pipe 31. The lower heat storage chamber 30 is located below the heating body 36. One end of the lower exhaust pipe 32 is located inside the lower heat storage chamber 30, and the other end extends to the outside of the upper baffle 22. The lower exhaust pipe 32 concentrates the gas in the lower heat storage chamber 30 for discharge. In order to protect the heating body 36, an outer frame 35 is installed on the outside of the heating body 36. In addition, the hot air generated by the heating body 36 is retained in the outer frame 35. A heat conduction pipe 37 is connected between the outer frame 35 and the upper heat storage chamber 29, and a heat conduction pipe 33 is connected between the outer frame 35 and the lower heat storage chamber 30. A vacuum pump 34 is installed on both the heat conduction pipe 37 and the heat conduction pipe 33. The vacuum pump 34 then sends the hot air in the outer frame 35 to the upper heat storage chamber 29 and the lower heat storage chamber 30 through the heat conduction pipe 37 and the heat conduction pipe 33, respectively.

[0033] The structure inside the lower baffle 24 is the same as that inside the upper baffle 22, and the structures inside the lower baffle 24 and the upper baffle 22 are symmetrically distributed vertically. Through the vertically symmetrical structure, the optimal gas flow path is designed, that is, the gas flow path of the upper baffle 22: part of the gas flows to the coil processing surface through the lower exhaust pipe 32, and part of the gas flows between the upper baffle 22 and the nozzle 18 through the upper exhaust pipe 31 and then moves downward. During this process, the paint falling on the upper baffle 22 can be further dried. The gas flow path of the lower baffle 24 is symmetrical to that of the upper baffle 22. Thus, the symmetrical structure allows the gas to act on the coil paint surface to the maximum extent, making the paint dry quickly, improving the quality of the paint and the appearance of the coil paint.

[0034] Example 3 Based on the above-described embodiment two, in order to precisely and quickly accelerate the drying of the paint on the coil side surface, such as... Figure 1 As shown, the liquid container 17 has a main concave hole 16, the nozzle 18 is located in the main concave hole 16, and multiple ventilation holes 19 are evenly provided on both sides of the main concave hole 16. The liquid container 17 is equipped with a drying module, and the hot air is precisely applied to the coil side surface through the ventilation holes 19 to achieve rapid drying of the surrounding paint.

[0035] Example 4 Based on the above embodiment three, in order to collect accidentally dripped paint and prevent the entire machine from getting dirty, such as Figure 5 and Figure 6 As shown, a base plate 6 is installed at the bottom of the two side upright plates 7. A base plate groove 10 is opened on the base plate 6. Plates 12 are symmetrically installed in the base plate groove 10. A gap is left between the two symmetrically installed plates 12 to form a flow channel 11. The top surface of the plate 12 is a downward inclined surface to facilitate the collection of sprayed paint.

[0036] Furthermore, such as Figure 6 As shown, a replacement solution is also provided. A partition is installed in the bottom plate groove 10, and multiple drip holes 5 are evenly opened on the partition. The drip holes 5 facilitate the collection of paint. In addition, the partition can be replaced periodically.

[0037] The working principle of this invention is as follows: the two ends of the coil are placed in the clamping plate 1 respectively, and the coil is fixed by the clamping claw 3, so that the two ends of the coil are taut. The angle of the nozzle 18 is adjusted by rotating the outer circular ring 13 or the inner circular ring 14, so that the nozzle 18 is aligned with the processing surface of the coil. The liquid body 17 moves to spray paint. During this process, the upper screw 23 and the lower screw 38 rotate, so that the upper stop block 22 and the lower stop block 24 move together along the moving direction of the liquid body 17. At the same time, the upper stop block 22 and the lower stop block 24 and the high-heat gas in the liquid body 17 directly act on the painted surface of the coil, accelerating the drying speed of the paint. The most preferred solution is to increase the paint thickness of the coil to 25μm, which can effectively reduce the coil being broken down during the layer test, forming a circuit with the powder and lead wire, thus solving the product failure problem and improving the product yield.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
