Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of enameled wire painting, and in particular to a micro enameled wire suspension mold painting device and painting method. BACKGROUND

[0002] In the traditional enameled wire production process, the method for removing excess paint on the surface of the enameled wire mainly relies on mutually adhered felt, but this method has significant defects: due to the limited control accuracy of the felt adhering surface, it is difficult to ensure the uniformity of the paint thickness, resulting in uneven paint film thickness of the enameled wire, which seriously affects the overall quality of the product.

[0003] In order to improve the uniformity of the paint film and the quality of the product, the industry gradually turns to using a suspension mold for painting. The suspension mold realizes uniform painting of the surface of the enameled wire by virtue of its precisely designed channel structure. However, with the diversification of the outer diameter of enameled wire products, fixed specification suspension molds cannot meet the painting needs of enameled wires of different outer diameters, so in the production process, the suspension mold needs to be frequently replaced and the position of the paint spraying head needs to be adjusted every time the outer diameter of the enameled wire changes.

[0004] However, the replacement operation of the suspension mold is currently mostly completed manually, including the steps of disassembling the old mold, installing the new mold, and precisely adjusting the position of the paint spraying head, and the operation process is relatively cumbersome and inefficient, which is difficult to meet the needs of modern efficient production. SUMMARY

[0005] The present application aims to at least partially solve one of the technical problems in the related art.

[0006] To this end, the present application aims to provide a micro enameled wire suspension mold painting device and painting method. The device integrates multiple groups of suspension molds with different inner diameter sizes to adapt to the painting needs of enameled wires of different outer diameter sizes. Through the close cooperation of the switching turntable seat and the synchronous driving assembly, the quick switching of the suspension mold and the precise adjustment of the position of the paint spraying head can be realized simultaneously, greatly simplifying the operation process and significantly improving the work efficiency.

[0007] To achieve the above objectives, this invention proposes a micro-enameled wire suspension mold coating device, comprising a main mounting frame, a secondary mounting frame, a conical coating box, a switching turntable base, a coating assembly, a synchronous drive assembly, and a spray head. The secondary mounting frame and the conical coating box are respectively fixedly connected to the surface of the main mounting frame and are arranged vertically along the Z-axis. The switching turntable base is rotatably connected to the surface of the secondary mounting frame, and multiple sets of U-shaped grooves and multiple sets of threaded holes are respectively formed at corresponding positions on the upper and lower surfaces of the switching turntable base. The coating assembly includes multiple sets of upper suspension molds and multiple sets of lower fixed molds, wherein the multiple sets of upper suspension molds are divided into... The sliding connection is made to the inner walls of multiple sets of U-shaped grooves, and the multiple sets of lower fixed molds are respectively threaded to the inner walls of multiple sets of threaded holes; the synchronous drive assembly includes an external drive mechanism and an internal drive mechanism, wherein the external drive mechanism is disposed on the surface of the secondary mounting frame and connected to the switching turntable seat, the internal drive mechanism is disposed on the inner wall of the conical paint box and connected to the external drive mechanism, and the paint spray head is fixedly connected to the surface of the internal drive mechanism; the enameled wire passes through the bottom of the main mounting frame, the inside of the conical paint box, the inside of the corresponding lower fixed mold, and the inside of the corresponding upper suspended mold in sequence from bottom to top.

[0039] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0040] The following description, in conjunction with the accompanying drawings, describes a micro-enameled wire suspension mold coating device and coating method according to an embodiment of the present invention.

[0041] like Figures 1-9 As shown, an embodiment of the present invention provides a micro-enameled wire suspension mold coating device, comprising a main mounting frame 1, a secondary mounting frame 2, a conical coating box 3, a switching turntable base 4, a coating assembly 5, a synchronous drive assembly 6, and a spray head 7. The secondary mounting frame 2 and the conical coating box 3 are fixedly connected to the surface of the main mounting frame 1 and are arranged vertically along the Z-axis. The switching turntable base 4 is rotatably connected to the surface of the secondary mounting frame 2. Multiple sets of U-shaped grooves 401 and multiple sets of threaded holes are respectively formed at corresponding positions on the upper and lower surfaces of the switching turntable base 4. The coating assembly 5 includes multiple sets of upper suspension molds 51 and multiple sets of lower fixed molds 52. The components are slidably connected to the inner walls of multiple sets of U-shaped grooves 401, and multiple sets of lower fixed molds 52 are threadedly connected to the inner walls of multiple sets of threaded holes. The synchronous drive assembly 6 includes an external drive mechanism 61 and an internal drive mechanism 62. The external drive mechanism 61 is disposed on the surface of the secondary mounting frame 2 and connected to the switching turntable seat 4. The internal drive mechanism 62 is disposed on the inner wall of the conical paint box 3 and connected to the external drive mechanism 61. The paint spray head 7 is fixedly connected to the surface of the internal drive mechanism 62. The enameled wire 8 passes through the bottom of the main mounting frame 1, the inside of the conical paint box 3, the inside of the corresponding lower fixed mold 52, and the inside of the corresponding upper suspended mold 51 in sequence from bottom to top.

[0042] It should be noted that the cone-shaped paint box 3 described in this embodiment is equipped with a discharge pipe at the bottom, and a valve is installed on the discharge pipe.

[0043] Specifically, in use, the enameled wire 8 is sequentially passed through the bottom of the main mounting frame 1, the bottom of the L-shaped plate frame 101, the inside of the conical coating box 3, the inside of the corresponding lower fixed mold 52, and the inside of the corresponding upper suspended mold 51. Then, paint is injected into the spray head 7 through the paint injection end 71. The paint is sprayed onto the surface of the enameled wire 8 located inside the conical coating box 3 by the spray head 7. During the conveying process, the thickness of the paint on the surface of the enameled wire 8 is processed by the lower fixed mold 52 and the upper suspended mold 51, resulting in a uniform distribution of paint on the surface of the enameled wire 8 with a consistent thickness. When it is necessary to coat enameled wires 8 with different outer diameters, the mold needs to be switched and the distance between the spray head 7 and the enameled wire 8 needs to be changed. Before the threading operation, the replaced paint... One end of the enameled wire 8 is fixed by the clamping mechanism 10, eliminating the need for manual pulling. Then, the synchronous drive component 6 is activated, synchronously driving the switching turntable 4 to rotate and the paint spray head 7 to move. The rotating switchtable 4 switches between different inner diameter painting components 5 to adapt to the painting needs of enameled wires 8 with different outer diameters. The moving paint spray head 7 adjusts the paint supply by changing the spraying distance to adapt to the painting needs of enameled wires 8 with different outer diameters. After the painting component 5 is adjusted, the replaced enameled wire 8 is passed through the inside of the switched painting component 5, and then the enameled wire 8 continues to be fed to realize the painting operation. When the enameled wire 8 breaks, the clamping mechanism 10 can automatically clamp and fix the enameled wire 8, facilitating subsequent wiring.

[0044] In one embodiment of the present invention, such as Figures 1-6As shown, elastic shock-absorbing pads 100 are fixedly connected to the connection points between the surface of the main mounting frame 1 and the surface of the external frame, the connection points between the surface of the secondary mounting frame 2 and the surface of the main mounting frame 1, and the connection points between the surface of the conical paint box 3 and the surface of the main mounting frame 1. The switching turntable base 4 includes a rotating shaft 41, an upper plate 42, and a lower plate 43. The rotating shaft 41 is rotatably connected to the surface of the secondary mounting frame 2. The upper plate 42 and the lower plate 43 are fixedly connected to the surface of the rotating shaft 41 and are arranged vertically along the Z-axis. Multiple sets of U-shaped grooves 401 and multiple sets of threaded holes are respectively opened on the surface of the upper plate 42 and the lower plate 43, and their positions are corresponding. A step portion 511 is provided on the surface of the upper suspension mold 51 at the position corresponding to the U-shaped groove 401. The step portion 511 slides. Connected to the inner wall of the U-shaped groove 401; the upper floating mold 51 and the lower fixed mold 52 are respectively provided with a first mold cavity 512 and a second mold cavity 521. The cross-sections of the first mold cavity 512 and the second mold cavity 521 are both conical. The inner diameter of the top opening of the first mold cavity 512 is smaller than the inner diameter of the top opening of the second mold cavity 521, and the inner diameter of the bottom opening of the first mold cavity 512 is smaller than the inner diameter of the bottom opening of the second mold cavity 521, but larger than the inner diameter of the top opening of the second mold cavity 521. The inner diameters of the first mold cavity 512 in the multiple sets of upper floating molds 51 and the second mold cavity 521 in the multiple sets of lower fixed molds 52 are not the same. The external drive mechanism 61 includes a driven gear 611, a driving gear 612, an adjusting handle 613, a synchronous shaft 614, and a worm gear 615, wherein the driven gear 611 is a passive gear 612, an adjusting handle 613, a synchronous shaft 614, and a worm gear 615. Gear 611 and driving gear 612 are rotatably connected to the surface of the secondary mounting bracket 2 and are arranged left and right along the Y-axis. The driven gear 611 meshes with the driving gear 612. One end of the central shaft of the driven gear 611 is fixedly connected to one end of the rotating shaft 41. The adjusting handle 613 is rotatably connected to the surface of the secondary mounting bracket 2 and is fixedly connected to one end of the central shaft of the driving gear 612. The synchronous shaft 614 is rotatably connected to the top of the conical paint box 3. One end of the synchronous shaft 614 is fixedly connected to one end of the central shaft of the driving gear 612, and the other end of the synchronous shaft 614 penetrates into the interior of the conical paint box 3 and is fixedly connected to a worm gear 615. The worm gear 615 is connected to the internal drive mechanism 62. The internal drive mechanism 62 includes a U-shaped fixed... The system comprises a U-shaped base 621, a threaded screw 622, a rectangular slide 623, and a worm gear 624. The U-shaped base 621 is fixedly connected to the inner wall of the conical paint box 3. The threaded screw 622 is rotatably connected to the inner wall of the U-shaped base 621. The rectangular slide 623 is threadedly connected to the outer surface of the threaded screw 622 and slidably connected to the inner wall of the U-shaped base 621. One end of the threaded screw 622 extends out of the U-shaped base 621 and is fixedly connected to the worm gear 624. The worm gear 624 is located on one side of the worm 615 and meshes with it. The paint spray head 7 is fixedly connected to the surface of the rectangular slide 623 and is oriented towards the enameled wire 8. The paint spray head 7 is connected to the paint injection end 71 fixedly connected to the top of the conical paint box 3 through a pipe.

[0045] Specifically, an elastic shock-absorbing pad 100 is provided to reduce the vibration force from the external frame and ensure the stability of the center position of the painting assembly 5. An upper plate 42 and a lower plate 43 are provided to respectively open U-shaped grooves 401 and threaded holes. The U-shaped grooves 401 facilitate the installation of the upper floating mold 51, and the threaded holes facilitate the fixing of the lower fixed mold 52. The upper floating mold 51 and the lower fixed mold 52 are respectively provided with a first mold cavity 512 and a second mold cavity 521. The cross-sections of the first mold cavity 512 and the second mold cavity 521 are both conical. The inner diameter of the top opening of the first mold cavity 512 is smaller than that of the top opening of the second mold cavity 521. The inner diameter allows for the removal of excess insulating varnish from the surface of the enameled wire 8 when it exits the second mold cavity 521, and a second removal of excess insulating varnish from the surface of the enameled wire 8 when it exits the first mold cavity 512. Since the amount of varnish applied to the enameled wire 8 after exiting the second mold cavity 521 is constant, the impact force exerted on the first mold cavity 512 during its routing remains consistent. By setting an upper suspension mold 51 of corresponding weight, the impact force exerted by the enameled wire 8 on the upper suspension mold 51 is offset by the weight of the upper suspension mold 51 itself, thus ensuring that the upper suspension mold 51... In operation, the stepped portion 511 can remain freely suspended along the inner wall of the U-shaped groove 401, preventing it from abutting against the upper plate 42 due to excessive impact. When the upper suspended mold 51 is suspended, the jumping and offset of the enameled wire 8 can drive the upper suspended mold 51 to move freely within the U-shaped groove 401, allowing the enameled wire 8 to pass straight through the center of the first mold cavity 512, effectively avoiding uneven paint film thickness and achieving good performance. An external drive mechanism 61 is provided to drive the switching turntable 4 to rotate, realizing the switching between the upper suspended mold 51 and the lower fixed mold 52. An internal drive mechanism 62 is provided to drive... The paint spray head 7 moves to adjust the amount of paint sprayed. In use, the adjustment handle 613 is turned. The rotation of the adjustment handle 613 synchronously drives the drive gear 612, the synchronous shaft 614 and the worm gear 615 to rotate. The rotation of the drive gear 612 synchronously drives the driven gear 611 and the switching turntable 4 to rotate, realizing the switching between the upper floating mold 51 and the lower fixed mold 52. The rotation of the worm gear 615 synchronously drives the worm wheel 624 and the threaded screw 622 to rotate. The rotation of the threaded screw 622 synchronously drives the rectangular slide 623 to move. The movement of the rectangular slide 623 synchronously drives the paint spray head 7 to move, realizing the adjustment of the amount of paint sprayed.

[0046] In one embodiment of the present invention, such as Figure 7As shown, the switching turntable base 4 also includes a switching anti-drop mechanism 9. The switching anti-drop mechanism 9 includes an arc-shaped slide 91, a plate-shaped slide 92, a first spring 93, a fixing piece 94, and an elastic locking head 95. The arc-shaped slide 91 is evenly opened on the surface of the upper plate 42 and is located on one side of the U-shaped groove 401. The plate-shaped slide 92 is slidably connected to the inner wall of the arc-shaped slide 91. One end of the plate-shaped slide 92 is fixedly connected to the inner wall of the arc-shaped slide 91 with the first spring 93. The other end of the plate-shaped slide 92 penetrates into the interior of the U-shaped groove 401 and abuts against the inner wall of the U-shaped groove 401. The fixing piece 94 is integrally formed on the surface of the plate-shaped slide 92. The elastic locking head 95 is set on the surface of the upper plate 42 and is located on the outside of the arc-shaped slide 91. The surface of the fixing piece 94 near the elastic locking head 95 has a locking hole and is locked and fixed with the elastic locking head 95.

[0047] It should be noted that the switching anti-drop mechanism 9 described in this embodiment is used to prevent the upper suspended mold 51 from falling out of the U-shaped groove 401 during the rotation of the switching turntable seat 4.

[0048] Specifically, in use, the plate-shaped slide 92 is moved to one side of the elastic locking head 95. The plate-shaped slide 92 moves and simultaneously squeezes the first spring 93, causing its other end to retract into the arc-shaped slide groove 91. When the locking hole on the fixing piece 94 engages with the elastic locking head 95, the position of the plate-shaped slide 92 is fixed. The above operation opens the U-shaped groove 401, making it easy to operate the upper suspension mold 51. When closing the U-shaped groove 401, the locking hole is separated from the elastic locking head 95. Under the elastic force of the first spring 93, the plate-shaped slide 92 returns to its original position, and one end of it re-enters the interior of the U-shaped groove 401 and abuts against the inner wall of the U-shaped groove 401, effectively preventing the upper suspension mold 51 from falling.

[0049] In one embodiment of the present invention, such as Figures 8-9As shown, the switching turntable base 4 also includes a clamping mechanism 10. The clamping mechanism 10 includes an L-shaped plate frame 101, multiple sets of mounting frames 102, multiple sets of pressure rollers 103, multiple sets of sliding frames 104, multiple sets of adjusting screws 105, and multiple sets of second springs 106. The L-shaped plate frame 101 is bolted to the surface of the main mounting frame 1 and is located on one side of the conical paint box 3. The multiple sets of mounting frames 102 are respectively fixedly connected to the surface of the L-shaped plate frame 101 and are arranged sequentially along the Z-axis. The multiple sets of pressure rollers 103 are slidably connected to the inner walls of the multiple sets of mounting frames 102, and the multiple sets of sliding frames 104 are slidably connected to the inner walls of the multiple sets of mounting frames 102. The mounting frame 102 is positioned to correspond to the positions of multiple pressure rollers 103. The central shafts of the multiple pressure rollers 103 extend through the outside of the mounting frame 102 and are fixedly connected to the surfaces of multiple sliding frames 104. Multiple adjusting screws 105 are threadedly connected to the surfaces of multiple sliding frames 104. One end of each adjusting screw 105 is threadedly connected to the surface of the mounting frame 102. Multiple second springs 106 are sleeved on the outside of the adjusting screws 105. One end of each second spring 106 is fixedly connected to the surface of the mounting frame 102, and the other end is fixedly connected to the surface of the sliding frame 104.

[0050] It should be noted that the clamping mechanism 10 described in this embodiment is used to fix the enameled wire 8 during threading without having to pull it by hand, and to automatically clamp and fix the enameled wire 8 when it breaks, so as to facilitate subsequent wiring by personnel.

[0051] Specifically, during use, the corresponding adjusting screw 105 is adjusted according to the outer diameter of the enameled wire 8, thereby changing the pressure of the corresponding pressure roller 103. When the enameled wire 8 is being conveyed, it drives the pressure roller 103 to move towards the adjusting screw 105. The movement of the pressure roller 103 synchronously drives the slide frame 104 to move and stretches the second spring 106. When the enameled wire 8 is disconnected, the enameled wire 8 no longer drives the pressure roller 103 to move towards the adjusting screw 105. Under the elastic force of the second spring 106, the pressure roller 103 moves towards the L-shaped plate frame 101 and presses down on the enameled wire 8, preventing it from shifting, which facilitates subsequent wiring by personnel.

[0052] In one embodiment of the present invention, such as Figure 9 As shown, multiple sets of pressure rollers 103 are respectively provided with annular limiting guide grooves 1031 on their surfaces. The enameled wire 8 is slidably connected to the inner wall of the annular limiting guide groove 1031. The multiple sets of annular limiting guide grooves 1031 are adapted to enameled wires 8 with different outer diameters. A steel ball 1032 is provided at the connection between the inner wall of the annular limiting guide groove 1031 and the enameled wire 8. The steel ball 1032 is rotatably connected to the inner wall of the annular limiting guide groove 1031 and contacts the surface of the enameled wire 8.

[0053] Specifically, the annular limiting guide groove 1031 is provided to facilitate the guidance of the enameled wire 8, and the steel ball 1032 is set to reduce the friction of the enameled wire 8 during transportation. In the absence of high-frequency vibration, when the enameled wire 8 breaks, the steel ball 1032 can stably press and fix the enameled wire 8.

[0054] A coating method for a micro-enameled wire suspension mold coating device includes the following steps:

[0055] S1: Pass the enameled wire 8 through the bottom of the main mounting frame 1, the bottom of the L-shaped plate frame 101, the inside of the conical paint box 3, the inside of the lower fixed mold 52 corresponding to its position, and the inside of the upper floating mold 51 corresponding to its position in sequence.

[0056] S2: Paint is injected into the paint head 7 through the paint injection end 71, and the paint is sprayed onto the surface of the enameled wire 8 located inside the conical paint box 3 through the paint spray head 7.

[0057] S3: During the conveying process, the thickness of the enamel coating on the surface of the enameled wire 8 is processed by the lower fixed mold 52 and the upper suspended mold 51, and the enamel coating is evenly distributed on the surface of the enameled wire 8 with a consistent thickness.

[0058] S4: When it is necessary to paint enameled wires 8 with different outer diameters, the mold needs to be switched and the distance between the paint spray head 7 and the enameled wire 8 needs to be changed. Before the wire threading operation, one end of the replaced enameled wire 8 is fixed by the clamping mechanism 10. There is no need to pull it by hand. Then, the synchronous drive component 6 is run. The synchronous drive component 6 drives the switching turntable 4 to rotate and the paint spray head 7 to move synchronously. The rotation of the switching turntable 4 switches the painting components 5 with different inner diameters to adapt to the painting requirements of enameled wires 8 with different outer diameters. The movement of the paint spray head 7 adjusts the paint supply by changing the spraying distance to adapt to the painting requirements of enameled wires 8 with different outer diameters.

[0059] S5: After the painting component 5 is adjusted, the replaced enameled wire 8 is passed through the inside of the switched painting component 5, and then the enameled wire 8 is continued to be fed to realize the painting operation.

[0060] S6: When the enameled wire 8 breaks, the clamping mechanism 10 can automatically clamp and fix the enameled wire 8, making it easier for subsequent personnel to connect the wire.

[0061] In summary, the micro-enameled wire suspension mold coating equipment and method of this invention integrates multiple suspension molds with different inner diameters to meet the coating needs of enameled wires 8 with different outer diameters. Through the close cooperation of the switching turntable 4 and the synchronous drive component 6, the suspension molds can be switched quickly and the position of the spray nozzle 7 can be adjusted precisely, greatly simplifying the operation process and significantly improving work efficiency. The device is equipped with a dual mold, which effectively reduces the impact force applied to the first mold cavity 512 and ensures the stability of the upper suspension mold 51 in suspension. The switching anti-drop mechanism 9 is used to prevent the upper suspension mold 51 from falling out of the U-shaped groove 401 during the rotation of the switching turntable 4. The clamping mechanism 10 is used to fix the enameled wire 8 during threading without having to pull it by hand, and to automatically clamp and fix the enameled wire 8 when it breaks, facilitating subsequent wiring.
