Description

Technical Field

[0001] This invention belongs to the technical field of enameling machines, specifically, it relates to an intelligent enameling machine based on visual sensing detection and its usage method. Background Technology

[0002] Currently, in the process of insulating the outer surface of metal conductors, enameling machines are commonly used to coat or spray insulating varnish onto the outer surface of the metal conductor, forming an insulating layer to prevent leakage. Generally, the insulating varnish is injected into a receiving tank, and the metal conductor is immersed in the varnish as it passes through the tank, thus coating its outer surface. Alternatively, atomizing spraying equipment is used to atomize and spray the insulating varnish onto the outer surface of the metal conductor. Of these two methods, the first, the immersion method, is prone to coating too thinly or too thickly, and it's impossible to adjust the immersion length based on the existing insulation layer on the metal conductor. The second, the atomizing spraying method, is prone to uneven spraying, resulting in inconsistent insulation layer thickness on the outer surface of the metal conductor, and in more serious cases, breakage points. Therefore, neither of these methods can produce metal conductors with high-quality insulation. Summary of the Invention

[0003] This invention provides an intelligent enameling machine based on visual sensing detection and its usage method. It is used to determine the uniformity and thickness of the insulating varnish layer on the outer surface of the conductor through visual detection, and adjust the length of the conductor immersed in the insulating varnish according to the detected data. It also applies additional varnish to the insulating varnish layer on the outer surface of the conductor to make the thickness of the insulating varnish layer on the outer surface of the conductor uniform, avoid the occurrence of breakpoints, and improve the insulation of the conductor.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A smart enameling machine based on visual sensing detection includes an impregnation tank, a visual detection mechanism, and a touch-up pre-drying mechanism arranged sequentially along the conveying direction of the wire. The impregnation tank is filled with paint liquid. A wheel-type inlet mechanism, a fixed guide mechanism, an adjustable guide mechanism, and a wheel-type outlet mechanism are arranged at intervals along the conveying direction of the wire on the impregnation tank. Multiple wires arranged side by side enter the impregnation tank through the wheel-type inlet mechanism and the fixed guide mechanism, and are exited from the impregnation tank through the adjustable guide mechanism and the wheel-type outlet mechanism.

[0006] Furthermore, the wheel-type guide mechanism includes a first transverse shaft and a plurality of first guide wheels. These first guide wheels are rotatably mounted on the first transverse shaft at intervals along the axis of the first transverse shaft. First vertical slide rails are symmetrically fixed on both sides of the upper end of the paint soaking tank. First sliding blocks are respectively mounted on both ends of the first transverse shaft. Each first sliding block is slidably mounted on the corresponding first vertical slide rail. A first vertical screw is threaded onto the first vertical slide rail. The lower end of the first vertical screw is rotatably connected to the first sliding block.

[0007] Furthermore, the fixed guide mechanism includes a second transverse shaft and a plurality of second guide wheels, which are rotatably mounted on the second transverse shaft at intervals along the axis of the second transverse shaft. The second transverse shaft extends into the lower part of the immersion tank, and the two ends of the second transverse shaft are respectively connected to the two side walls of the immersion tank.

[0008] Furthermore, the adjustable guide mechanism includes multiple longitudinal adjustment components arranged side by side outside the immersion tank. The output end of each longitudinal adjustment component extends into the immersion tank from the lower part of the immersion tank along the longitudinal direction of the immersion tank. A guide wheel seat is installed at the output end of each longitudinal adjustment component, and a fourth guide wheel is rotatably mounted on the guide wheel seat.

[0009] Furthermore, the wheel-type guide mechanism includes a third transverse shaft and multiple third guide wheels. These third guide wheels are rotatably mounted on the third transverse shaft at intervals along its axis. Second vertical slide rails are symmetrically slidably mounted on both sides of the upper end of the immersion tank. Second sliding blocks are respectively mounted on both ends of the third transverse shaft. Each second sliding block is slidably mounted on a corresponding second vertical slide rail. A second vertical screw is threadedly connected to the second vertical slide rail. The lower end of the second vertical screw is rotatably connected to the second sliding block. An adapter is mounted on the third transverse shaft. One end of the longitudinal adjusting screw is threadedly connected to the adapter, and the longitudinal adjusting screw is threadedly connected to the immersion tank.

[0010] Furthermore, the visual inspection mechanism includes two horizontal mounting seats arranged vertically and staggered from each other. Multiple image acquisition devices are installed at intervals on each horizontal mounting seat, and these image acquisition devices are arranged one-to-one with the wires. Each horizontal mounting seat is slidably connected to both ends of a longitudinal adjustment seat, and a third vertical lead screw is threadedly connected to each longitudinal adjustment seat. The lower end of the third vertical lead screw is rotatably connected to a fixed seat.

[0011] Furthermore, the paint-touch pre-drying mechanism includes an assembly connected to a vision inspection mechanism. Multiple angle-adjusting paint-touching units are constructed on the assembly at lateral intervals. A vortex pre-drying unit is provided inside the assembly and at the outlet end of each angle-adjusting paint-touching unit. Each of the wires passes through the angle-adjusting paint-touching unit and the vortex pre-drying unit in sequence.

[0012] Furthermore, the angle-adjustable touch-up paint unit includes an atomizing hood rotatably mounted on the assembly body. The diameter of the atomizing hood decreases along the conveying direction of the wire. An atomizing cavity is formed between the atomizing hood and the assembly body. Multiple atomizing holes are opened on one side of the circumferential surface of the atomizing hood. Multiple guide ports are evenly opened along the circumference of the large-diameter end of the atomizing hood. An annular liquid collecting groove communicating with each atomizing hole is opened on the assembly body. A paint inlet branch pipe and a liquid collecting branch pipe are installed on the assembly body. The paint inlet branch pipe and the liquid collecting branch pipe are respectively connected to the atomizing cavity and the annular liquid collecting groove. The atomizing hood is drivenly connected to the angle adjustment unit.

[0013] Furthermore, the cyclone pre-drying unit includes a detachable air guide hood assembled into the assembly body. The diameter of the air guide hood increases along the conveying direction of the wire. An air guide cavity is formed between the air guide hood and the assembly body. Multiple cyclone air outlets are evenly opened on the peripheral wall of the air guide hood along its circumference. An air inlet branch pipe is installed on the assembly body, and the air inlet branch pipe is connected to the air guide cavity.

[0014] This invention discloses a method for using the above-mentioned intelligent enameling machine based on visual sensing detection, comprising the following steps:

[0015] Step 1. Immerse multiple wires sequentially in a paint bath, a visual inspection mechanism, and a touch-up pre-drying mechanism;

[0016] Step 2. Control the vision inspection mechanism to continuously inspect each wire and detect the thickness of the paint layer on the wire surface;

[0017] Step 3. When it is detected that the local thickness of the paint layer on the surface of the conductor is too thin, control the paint-replenishing pre-drying mechanism to replenish the paint in the area where the paint layer on the surface of the conductor is too thin. After replenishment, perform pre-drying treatment.

[0018] Step 4. When it is detected that the overall enamel layer on the surface of the conductor is too thin or too thick, control the position of the adjustable guide mechanism and / or the wheel-type delivery mechanism in the immersion tank to adjust the length of the conductor immersed in the immersion tank.

[0019] The present invention, by employing the aforementioned structure, achieves the following technological advancements compared to existing technologies: The conductor enters the impregnation tank via the wheel-type inlet mechanism of the present invention, sequentially passes through a fixed guide mechanism and an adjustable guide mechanism, and is then exited from the impregnation tank via the wheel-type outlet mechanism. During the passage of the conductor through the visual inspection mechanism, the visual inspection mechanism performs image detection and recognition on the outer surface of the conductor, determining the thickness of the insulating varnish layer and the presence of breaks, etc. Subsequently, it controls the adjustable guide mechanism to adjust the length of one or more conductors immersed in the varnish solution in the impregnation tank, ensuring that the thickness of the insulating varnish layer on the surface of the conductor reaches the expected range after exiting the impregnation tank. As the conductor leaves the visual inspection mechanism, if the mechanism detects areas of excessive thinness or breaks in the conductor's outer surface, the conductor enters the pre-drying mechanism. This mechanism atomizes and sprays the varnish onto these thin or broken areas, thus filling in the gaps in the insulation layer. After this pre-drying, the mechanism preheats the insulation layer, causing it to initially solidify. This prevents the insulation layer from thinning at the top and thickening at the bottom due to gravity before the conductor enters the drying chamber. In summary, this invention uses visual inspection to determine the uniformity and thickness of the insulation layer on the conductor's outer surface. Based on the detected data, it adjusts the immersion length of the conductor in the insulation layer and performs pre-drying, resulting in a uniform thickness of the insulation layer and preventing breaks, thereby improving the conductor's insulation performance.

Detailed Implementation

[0038] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0039] This invention discloses an intelligent enameling machine based on visual sensing detection, such as... Figure 1-15As shown, the invention includes a paint immersion tank 100, a visual inspection mechanism 600, and a paint-touch pre-drying mechanism 700. The paint immersion tank 100, visual inspection mechanism 600, and paint-touch pre-drying mechanism 700 are arranged sequentially along the conveying direction of the guide wire 800. Paint liquid is filled into the paint immersion tank 100. The invention also includes a wheel-type inlet mechanism 200, a fixed guide mechanism 300, an adjustable guide mechanism 400, and a wheel-type outlet mechanism 500 on the paint immersion tank 100. These mechanisms are spaced apart along the conveying direction of the guide wire 800. Multiple guide wires 800 arranged side-by-side enter the paint immersion tank 100 through the wheel-type inlet mechanism 200 and the fixed guide mechanism 300, and then exit the paint immersion tank 100 sequentially through the adjustable guide mechanism 400 and the wheel-type outlet mechanism 500. The working principle and advantages of this invention are as follows: the conductor 800 enters the varnish-immersing tank 100 through the wheel-type inlet mechanism 200 of this invention, passes through the fixed guide mechanism 300 and the adjustable guide mechanism 400 in sequence, and is then exited from the varnish-immersing tank 100 through the wheel-type outlet mechanism 500; during the process of the conductor 800 passing through the visual inspection mechanism 600, the visual inspection mechanism 600 performs image detection and recognition on the outer surface of the conductor 800, determines the thickness of the insulating varnish layer on the outer surface of the conductor 800 and whether there are any breaks, etc., and then controls the action of the adjustable guide mechanism 400 to adjust the length of one or more conductors 800 immersed in the varnish liquid in the varnish-immersing tank 100, so as to ensure that the thickness of the insulating varnish layer on the surface of the conductor 800 reaches the expected range after it is exited from the varnish-immersing tank 100. As the wire 800 leaves the visual inspection mechanism 600, if the visual inspection mechanism 600 detects that the outer surface of the wire 800 is locally too thin or has a break, then after the wire 800 enters the paint-touch pre-drying mechanism 700, the paint-touch pre-drying mechanism 700 is activated. The paint is atomized and sprayed onto the areas where the insulating varnish layer of the wire 800 is too thin or has a break, thereby filling in the insulating varnish layer of the wire 800. After the paint touch-up is completed, the paint-touch pre-drying mechanism 700 preheats the insulating varnish layer, causing the insulating varnish layer to initially solidify, thus preventing the insulating varnish layer of the wire 800 from becoming thinner at the top and thicker at the bottom under the action of gravity before entering the drying chamber. In summary, the present invention can determine the uniformity and thickness of the insulating varnish layer on the outer surface of the conductor 800 through visual inspection, and adjust the length of the conductor 800 immersed in the insulating varnish according to the detected data, and apply additional varnish to the insulating varnish layer on the outer surface of the conductor 800, so that the thickness of the insulating varnish layer on the outer surface of the conductor 800 is uniform, and the occurrence of breakpoints is avoided, thereby improving the insulation of the conductor 800.

[0040] As a preferred embodiment of the present invention, such as Figure 4 , 5As shown, the wheel-type guide mechanism 200 includes a first transverse shaft 201 and a plurality of first guide wheels 202. These first guide wheels 202 are spaced apart on the first transverse shaft 201 along its axis, and each first guide wheel 202 is coaxially rotatably connected to the first transverse shaft 201. In this embodiment, first vertical slide rails 203 are symmetrically fixedly installed on both sides of the upper end of the paint impregnation tank 100. First sliding blocks 204 are respectively installed at both ends of the first transverse shaft 201. Each first sliding block 204 is slidably mounted on the corresponding first vertical slide rail 203. A first vertical lead screw 205 is threadedly connected to the first vertical slide rail 203. The lower end of the first vertical lead screw 205 is rotatably connected to the first sliding block 204, and the upper end of the first vertical lead screw 205 is equipped with a first operating handwheel 206. The wire 800 is guided to the fixed guide mechanism 300 via the corresponding first guide wheel 202. By manipulating the first operating handwheel 206, the first vertical lead screw 205 drives the first horizontal shaft 201 to move vertically via the first sliding block 204, thus adjusting the angle at which the wire 800 is guided to the fixed guide mechanism 300. This ensures that wires 800 of different radial lengths are smoothly and easily guided into the fixed guide mechanism 300. The fixed guide mechanism 300 in this embodiment includes a second horizontal shaft 301 and multiple second guide wheels 302. These second guide wheels 302 are spaced apart on the second horizontal shaft 301 along its axis, and each second guide wheel 302 is coaxially rotatably connected to the second horizontal shaft 301. The second horizontal shaft 301 extends into the lower part of the immersion tank 100 and is immersed in the paint solution. Both ends of the second horizontal shaft 301 are connected to the two side walls of the immersion tank 100, respectively. The wire 800 is guided to the adjustable guide mechanism 400 via the corresponding second guide wheel 302.

[0041] As a preferred embodiment of the present invention, such as Figure 6 , 7As shown, the adjustable guide mechanism 400 includes multiple longitudinal adjusting members 401. The longitudinal adjusting members 401 are electric cylinders, pneumatic cylinders, or hydraulic cylinders; generally, electric cylinders are used. These longitudinal adjusting members 401 are arranged side-by-side outside the impregnation tank 100, and are fixedly mounted on a transverse mounting plate 405, which is connected to the impregnation tank 100 via a longitudinal mounting plate 406. In this embodiment, the output rod 402 of each longitudinal adjusting member 401 extends longitudinally from the lower part of the impregnation tank 100 into the tank. A guide wheel seat 403 is mounted at the end of the output rod 402 of each longitudinal adjusting member 401, and a fourth guide wheel 404 is rotatably mounted on the guide wheel seat 403. The working principle and advantages of this embodiment are as follows: During the visual inspection process of multiple wires 800 by the visual inspection mechanism 600, when an abnormality is detected in the insulating varnish layer on one or more wires 800, the corresponding one or more longitudinal adjustment components 401 are controlled to move. This causes the longitudinal adjustment component 401 to control the corresponding guide wheel seat 403 to move along the longitudinal direction of the varnish pool 100 within the varnish pool 100, thereby adjusting the length of the wire 800 between the second guide wheel 302 and the fourth guide wheel 404. This achieves the purpose of adjusting the varnish immersion time and immersion length of the wire 800, and thus adjusting the thickness of the insulating varnish layer on the outer surface of the wire 800. Furthermore, this embodiment can simultaneously perform varnishing operations on multiple conductors 800 with different radial lengths, controlling the movement of each longitudinal adjustment component 401 so that the longitudinal positions of each fourth guide wheel 404 within the varnishing tank 100 are different. Specifically, when guiding a thinner conductor 800, the distance between the second guide wheel 302 and the fourth guide wheel 404 is shorter to avoid prolonged contact between the varnish and the conductor 800, resulting in an excessively thick insulating varnish layer. When guiding a thicker conductor 800, the distance between the second guide wheel 302 and the fourth guide wheel 404 is longer to avoid insufficient contact between the varnish and the conductor 800, resulting in an excessively thin insulating varnish layer.

[0042] As a preferred embodiment of the present invention, such as Figure 6-8As shown, the wheel-type guide mechanism 500 includes a third transverse shaft 501 and a plurality of third guide wheels 502. These third guide wheels 502 are spaced apart along the axis of the third transverse shaft 501, and each third guide wheel 502 is coaxially rotatably mounted on the third transverse shaft 501. In this embodiment, second vertical slide rails 503 are symmetrically arranged on both sides of the upper end of the paint impregnation tank 100. A sliding seat 504 is constructed at the lower end of each second vertical slide rail 503. Each sliding seat 504 is slidably connected to the upper end of the paint impregnation tank 100 and can slide along the longitudinal direction of the paint impregnation tank 100. Second sliding blocks 505 are respectively installed at both ends of the third transverse shaft 501. Each second sliding block 505 is slidably mounted on a corresponding second vertical slide rail 503. A second vertical lead screw 506 is threadedly connected to the second vertical slide rail 503. The lower end of the second vertical lead screw 506 is rotatably connected to the second sliding block 505, and a second operating handwheel 507 is installed at the upper end of the second vertical lead screw 506. In this embodiment, an adapter 508 is installed on the third transverse shaft 501. One end of the longitudinal adjusting screw 509 is threadedly connected to the adapter 508, and a third operating handwheel 510 is installed at the other end of the longitudinal adjusting screw 509. The longitudinal adjusting screw 509 is also threadedly connected to the impregnation tank 100. The working principle and advantages of this embodiment are as follows: the wire 800 is guided to the corresponding third guide wheel 502 via the corresponding fourth guide wheel 404, and by manipulating the second operating handwheel 507, the second vertical lead screw 506 drives the third horizontal shaft 501 to move vertically via the second sliding block 505. Simultaneously, the third operating handwheel 510 can be rotated to adjust the relative horizontal position of the wheel-type guide mechanism 500 and the immersion tank 100, thereby adjusting the angle at which the wire 800 is guided to the third guide wheel 502. This ensures that wires 800 of different radial lengths are smoothly and easily guided into the third guide wheel 502. By adjusting the relative horizontal position of the wheel-type guide mechanism 500 and the immersion tank 100, the length of the wire 800 between the fourth and third guide wheels can be adjusted, thereby changing the length of the wire 800 extending obliquely from the varnish, ensuring that the thickness and uniformity of the insulating varnish layer on the surface of the wire 800 of the corresponding radial length reaches a predetermined range.

[0043] As a preferred embodiment of the present invention, such as Figure 9 , 10As shown, the visual inspection mechanism 600 includes two horizontal mounting bases 603, which are vertically arranged and staggered. Multiple image acquisition units 604 are installed at intervals on each horizontal mounting base 603, and these image acquisition units 604 are correspondingly arranged with multiple wires 800. This embodiment includes two longitudinal adjustment bases 601, with the two horizontal mounting bases 603 positioned between them. Two longitudinal slide rails 602 are respectively provided on the end faces of the two longitudinal adjustment bases 601 that are close to each other, and these two longitudinal slide rails 602 are vertically arranged on the longitudinal adjustment bases 601. The two ends of each horizontal mounting base 603 are slidably connected to the corresponding two longitudinal slide rails 602, thereby achieving the purpose of sliding connection between the horizontal mounting base 603 and the two longitudinal adjustment bases 601. A third vertical lead screw 606 is threaded onto each longitudinal adjusting seat 601. A fixed seat 605 is rotatably connected to the lower end of the third vertical lead screw 606, and a fourth operating handwheel 607 is fitted to the upper end of the third vertical lead screw 606. The fixed seat 605 is mounted on a support frame. In this embodiment, the horizontal distance between the two transverse mounting seats 603 can be adjusted, as can the vertical distance between the two transverse mounting seats 603, ensuring that the image acquisition device 604 can accurately acquire the thickness and breakpoints of the outer insulating varnish layer of the corresponding conductor 800.

[0044] As a preferred embodiment of the present invention, such as Figure 11-15 As shown, the paint-touch pre-drying mechanism 700 includes an assembly 701. Connecting plates 727 are detachably connected to both sides of the assembly 701, and each connecting plate 727 is connected to a corresponding longitudinal adjusting seat 601. In this embodiment, multiple angle-adjusting paint-touch units are constructed on the assembly 701. These angle-adjusting paint-touch units are spaced laterally along the assembly 701. The assembly 701 contains the same number of vortex pre-drying units as the angle-adjusting paint-touch units. Each vortex pre-drying unit is located at the outlet end of the corresponding angle-adjusting paint-touch unit. Each wire 800 passes sequentially through the corresponding angle-adjusting paint-touch unit and the vortex pre-drying unit. The angle-adjusting paint-touch unit adjusts the spray angle. After adjustment, the paint is atomized and sprayed onto the area of ​​the wire 800 to be touched up. After the paint is touched up, hot air is swirled out from the vortex pre-drying unit and spirally blown onto the outer circumference of the wire 800, thereby pre-drying the insulating varnish layer on the outer surface of the guide.

[0045] As a preferred embodiment of the present invention, such as Figure 12-15As shown, the angle-adjustable touch-up paint unit includes an atomizing cover 702 and an angle adjustment unit. The atomizing cover 702 is rotatably mounted within the assembly 701. The diameter of the atomizing cover 702 decreases along the conveying direction of the guide wire 800. An atomizing cavity 705 is formed between the atomizing cover 702 and the assembly 701. A first conductive channel 703 is formed within the atomizing cover 702, and the diameter of the first conductive channel 703 decreases along the conveying direction of the guide wire 800. Multiple atomizing holes 704 are formed on one side of the circumference of the atomizing cover 702. Multiple guide ports 706 are evenly formed circumferentially at the large-diameter end of the atomizing cover 702. An annular liquid collecting groove 708 is formed on the assembly 701, coinciding with the axis of the atomizing cover 702, and connected to each atomizing hole 704. Furthermore, a mounting flange extending radially inward is constructed at the large-diameter end of the atomizing cover 702. A mounting sleeve 711 is coaxially mounted on this mounting flange. A fixed end cap 707 is provided at the large-diameter end of the atomizing cover 702. The fixed end cap 707 is fitted onto the mounting sleeve 711 and is rotatably connected to the mounting sleeve 711. The fixed end cap 707 is detachably connected to the assembly body 701 by multiple fastening bolts. The angle adjustment unit of this embodiment includes a drive motor 713, a drive pulley 714, a driven pulley 712, and a synchronous belt 715. The drive motor 713 is mounted on the assembly body 701. The drive pulley 714 is coaxially mounted on the output shaft of the drive motor 713. The driven pulley 712 is coaxially mounted on the outside of the mounting sleeve 711. The synchronous belt 715 drives and connects the drive pulley 714 and the driven pulley 712. In this embodiment, a paint inlet branch pipe 721 and a liquid collection branch pipe 709 are installed on the assembly 701. The paint inlet branch pipe 721 and the liquid collection branch pipe 709 are respectively connected to the atomization chamber 705 and the annular liquid collection tank 708. A paint inlet control valve 722 is installed on the paint inlet branch pipe 721, and the paint inlet branch pipe 721 is connected to the paint inlet main pipe 723. The paint inlet main pipe 723 is connected to the paint storage tank for holding paint liquid through a pressure pump. The liquid collection branch pipe 709 is connected to the liquid collection main pipe 710, and the outlet end of the liquid collection main pipe 710 is connected to the liquid collection tank.The working principle and advantages of this embodiment are as follows: the wire 800 moves from its large-diameter end to its small-diameter end through the axis of the first conductive channel 703. The drive motor 713 drives the atomizing cover 702 to rotate a certain angle through the transmission of the pulley, so that the atomizing holes 704 on the atomizing cover 702 face the part of the wire 800 to be touched up with paint. At this time, the paint liquid is pumped into the atomizing chamber 705, and then atomized and sprayed onto the part of the wire 800 to be touched up with paint through the atomizing holes 704, thereby ensuring the surface of the insulating paint layer. The atomizing hood 702 is uniform, and because it is funnel-shaped, when the paint liquid is atomized and enters the first guiding channel 703, the atomized paint liquid tilts and faces away from the vortex pre-drying unit, thus preventing the atomized paint liquid from entering the vortex pre-drying unit. Excess paint liquid entering the first guiding channel 703 will gradually gather at the large diameter end of the atomizing hood 702, and then enter the annular collection tank 708 through the guide port 706, and finally enter the collection tank through the collection branch pipe 709 and the collection main pipe 710.

[0046] As a preferred embodiment of the present invention, such as Figure 13-15 As shown, the cyclone pre-drying unit includes an air guide hood 716, the diameter of which increases along the conveying direction of the guide wire 800. A connecting flange 719 extending radially outward is constructed at the large diameter end of the air guide hood 716. The connecting flange 719 is detachably connected to the assembly 701 by multiple connecting bolts. A second conductive channel 717 is formed inside the air guide hood 716. An air guide cavity 720 is formed between the air guide shroud 716 and the assembly 701. Multiple swirling air outlets 718 are evenly opened along the circumference of the peripheral wall of the air guide shroud 716. The second guiding channel 717 is connected to the air guide cavity 720 through these swirling air outlets 718. An air inlet branch pipe 724 is installed on the assembly 701. The air inlet branch pipe 724 is connected to the air guide cavity 720. An air inlet control valve 725 is installed on the air inlet branch pipe 724. The air inlet branch pipe 724 is connected to the air inlet main pipe 726. Clean hot air enters the air inlet main pipe 726, the air inlet branch pipe 724 and the air guide cavity 720 in sequence. Then, it enters the second guiding channel 717 through each swirling air outlet 718. Furthermore, because the air guide shroud 716 has a trumpet-shaped structure, after the hot air enters the second conductive channel 717, it moves in a spiral shape away from the angle-adjustable paint touch-up unit, thereby preventing the hot air from entering the angle-adjustable paint touch-up unit and affecting the atomized paint touch-up operation; moreover, the swirling hot air can fully cover the outer circumference of the conductor 800, ensuring that the insulating varnish layer on the outer circumference of the conductor 800 is synchronously and fully pre-dried. Moreover, in this embodiment, both the paint inlet control valve 722 and the air inlet control valve 725 are solenoid valves, so as to allow for the individual opening of a paint inlet branch pipe 721 or an air inlet branch pipe 724.

[0047] This invention discloses a method for using the above-mentioned intelligent enameling machine based on visual sensing detection, comprising the following steps:

[0048] Step 1. Immerse multiple wires 800 sequentially in the paint bath 100, the visual inspection mechanism 600, and the paint-touch pre-drying mechanism 700;

[0049] Step 2. Control the vision inspection mechanism 600 to continuously inspect each wire 800 and detect the thickness of the paint layer on the surface of the wire 800;

[0050] Step 3. When it is detected that the local thickness of the paint layer on the surface of the conductor 800 is too thin, control the paint-replenishing pre-drying mechanism 700 to replenish the paint in the area where the paint layer on the surface of the conductor 800 is too thin. After replenishment, pre-drying treatment is performed.

[0051] Step 4. When it is detected that the overall coating layer on the surface of the wire 800 is too thin or too thick, control the position of the adjustable guide mechanism 400 and / or the wheel assembly type delivery mechanism 500 in the immersion tank 100 to adjust the length of the wire 800 immersed in the immersion tank 100.

[0052] Finally, it should be noted that the above descriptions 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.
