Description

Technical Field

[0001] The present invention belongs to the technical field of enameling machines, and in particular, relates to an intelligent enameling machine based on visual sensing detection and a method for using the same. Background Art

[0002] At present, in the process of insulating the outer surface of metal wires, an enameling machine is often used to coat or spray insulating varnish on the outer surface of the metal wire to form an insulating layer on its surface to avoid leakage of the metal surface. Generally, the insulating varnish is injected into the receiving tank, and the metal wire is immersed in the insulating varnish during the process of passing through the receiving tank, so that the insulating varnish is coated on the outer surface of the metal wire; or an atomizing spray device is used to atomize and spray the insulating varnish on the outer surface of the metal wire. There are two methods. The first is the immersion method, which is very easy to cause the coating to be too thin or too thick, and it is impossible to adjust the length of the wire immersed in the insulating varnish in real time according to the situation of the insulating layer coated on the metal wire; the second is the atomizing spraying method, which is very easy to cause uneven spraying, resulting in uneven thickness of the insulating layer on the outer surface of the metal wire, and more seriously, breakpoints; therefore, both methods cannot obtain high-quality insulating metal wires.

When the wire leaves the visual inspection mechanism, since the visual inspection mechanism detects that the local thickness of the outer surface of the wire is too thin or there are breakpoints, in this way, after the wire enters the paint replenishing type pre-drying mechanism, the paint replenishing type pre-drying mechanism is controlled to act, and the paint liquid is atomized and sprayed at the place where the insulating paint layer of the wire is too thin or at the breakpoint, thereby replenishing the insulating paint layer of the wire. After the paint replenishment is completed, the paint replenishing type pre-drying mechanism pre-heats the insulating paint layer to make the insulating paint layer initially solidify, so as to avoid the situation that the upper part of the insulating paint layer becomes thinner and the lower part becomes thicker under the action of gravity before the wire enters the drying chamber.

Detailed implementation mode

[0038] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0039] The present invention discloses an intelligent enameling machine based on vision - sensing detection, as Figures 1-15As shown, the paint immersion tank 100, the visual inspection mechanism 600 and the touch-up paint pre-drying mechanism 700 are included, and the paint immersion tank 100, the visual inspection mechanism 600 and the touch-up paint pre-drying mechanism 700 are sequentially arranged along the conveying direction of the wire 800, and the paint liquid is filled in the paint immersion tank 100. The present invention is provided with a wheel group type introduction mechanism 200, a fixed guide mechanism 300, an adjustable guide mechanism 400 and a wheel group type output mechanism 500 on the paint immersion tank 100, and the wheel group type introduction mechanism 200, the fixed guide mechanism 300, the adjustable guide mechanism 400 and the wheel group type output mechanism 500 are arranged at intervals along the conveying direction of the wire 800. A plurality of wires 800 arranged side by side enter the paint immersion tank 100 through the wheel group type introduction mechanism 200 and the fixed guide mechanism 300, and then are sequentially output from the paint immersion tank 100 through the adjustable guide mechanism 400 and the wheel group type output mechanism 500. The working principle and advantages of the present invention are as follows: the conductor 800 enters the paint immersion tank 100 through the wheel-type introduction mechanism 200 of the present invention, passes through the fixed guide mechanism 300 and the adjustable guide mechanism 400 in turn, and then is led out of the paint immersion tank 100 through the wheel-type lead-out mechanism 500; in 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 paint layer on the outer surface of the conductor 800 and whether there are breakpoints, etc., and then controls the adjustable guide mechanism 400 to operate, adjusts the length of one or more conductors 800 immersed in the paint liquid in the paint immersion tank 100, and ensures that after the conductor 800 is led out of the paint immersion tank 100, the thickness of the insulating paint layer on its surface reaches the expected range. When the wire 800 leaves the visual inspection mechanism 600, since the visual inspection mechanism 600 detects that the local thickness of the outer surface of the wire 800 is too thin or there are breakpoints, after the wire 800 enters the paint touch-up type pre-drying mechanism 700, the paint touch-up type pre-drying mechanism 700 is controlled to operate, and the paint liquid is atomized and sprayed on the thin parts or breakpoints of the insulating paint layer of the wire 800, thereby filling the insulating paint layer of the wire 800. After the paint touch-up is completed, the paint touch-up type pre-drying mechanism 700 preheats the insulating paint layer to make the insulating paint layer initially solidify, thereby preventing the insulating paint layer of the wire 800 from becoming thinner at the top and thicker at the bottom due to the action of gravity before entering the drying room. In summary, the present invention can determine the uniformity and thickness of the insulating paint layer on the outer surface of the conductor 800 through visual inspection, and adjust the length of the conductor 800 immersed in the insulating paint according to the detected data, and touch up the insulating paint layer on the outer surface of the conductor 800, so that the thickness of the insulating paint 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, Figure 4 , 5As shown in the figure, the wheel group type lead-in mechanism 200 includes a first transverse shaft 201 and a plurality of first guide wheels 202. These first guide wheels 202 are assembled on the first transverse shaft 201 at intervals along the axis of the first transverse shaft 201, 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 and fixedly installed on both sides of the upper end of the dipping paint tank 100. First sliding blocks 204 are respectively assembled at both ends of the first transverse shaft 201. Each first sliding block 204 is slidably assembled 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 a first operating handwheel 206 is assembled at the upper end of the first vertical lead screw 205. The wire 800 is guided by the corresponding first guide wheel 202 to the fixed type guiding mechanism 300. By operating the first operating handwheel 206, the first vertical lead screw 205 drives the first transverse shaft 201 to move vertically through the first sliding block 204, so that the angle of the wire 800 guided by the fixed type guiding mechanism 300 is adjusted, ensuring that the wires 800 with different radial lengths are smoothly and smoothly led into the fixed type guiding mechanism 300. The fixed type guiding mechanism 300 of this embodiment includes a second transverse shaft 301 and a plurality of second guide wheels 302. These second guide wheels 302 are assembled on the second transverse shaft 301 at intervals along the axis of the second transverse shaft 301, and each second guide wheel 302 is coaxially rotatably connected to the second transverse shaft 301. The second transverse shaft 301 extends into the lower part of the dipping paint tank 100 and is immersed in the paint liquid. Both ends of the second transverse shaft 301 are connected to the two side walls of the dipping paint tank 100. The wire 800 is guided by the corresponding second guide wheel 302 to the adjustable type guiding mechanism 400.

[0041] As a preferred embodiment of the present invention, as Figure 6 、 7As shown in the figure, the adjustable guiding mechanism 400 includes a plurality of longitudinal adjusting members 401. The longitudinal adjusting members 401 are electric cylinders, air cylinders or oil cylinders. Generally, electric cylinders are used. These longitudinal adjusting members 401 are arranged side by side outside the dipping tank 100, and these longitudinal adjusting members 401 are fixedly installed on the transverse mounting plate 405, and the transverse mounting plate 405 is connected to the dipping tank 100 through the longitudinal mounting plate 406. In this embodiment, the output rod 402 of each longitudinal adjusting member 401 extends into the dipping tank 100 from the lower part of the dipping tank 100 along the longitudinal direction of the dipping tank 100. A guide wheel seat 403 is installed at the end of the output rod 402 of each longitudinal adjusting member 401, and a fourth guide wheel 404 is rotatably assembled on the guide wheel seat 403. The working principle and advantages of this embodiment are as follows: During the visual inspection of multiple wires 800 by the visual inspection mechanism 600, when one or more abnormal insulation paint layers are detected on the wires 800, the corresponding one or more longitudinal adjusting members 401 are controlled to act, so that the longitudinal adjusting members 401 control the corresponding guide wheel seats 403 to move in the dipping tank 100 along the longitudinal direction of the dipping tank 100, thereby adjusting the length of the wire 800 between the second guide wheel 302 and the fourth guide wheel 404, so as to achieve the purpose of adjusting the length of the wire 800 immersed in the paint liquid, adjusting the dipping time and dipping length of the wire 800, and enabling the thickness of the insulation paint layer on the outer surface of the wire 800 to be adjusted. Moreover, in this embodiment, wires 800 with multiple different radial lengths can be simultaneously dipped, and the longitudinal adjusting members 401 are controlled to act, so that the longitudinal positions of the fourth guide wheels 404 in the dipping tank 100 are different. That is, when guiding a thinner wire 800, the distance between the second guide wheel 302 and the fourth guide wheel 404 is shorter, avoiding the situation that the paint liquid contacts the wire 800 for too long and causing the insulation paint layer to be too thick; when guiding a thicker wire 800, the distance between the second guide wheel 302 and the fourth guide wheel 404 is longer, avoiding the situation that the paint liquid contacts the wire 800 for too short and causing the insulation paint layer to be too thin.

[0042] As a preferred embodiment of the present invention, as Figures 6-8As shown, the wheel set type lead-out mechanism 500 includes a third transverse shaft 501 and a plurality of third guide wheels 502. These third guide wheels 502 are arranged at intervals along the axis of the third transverse shaft 501, and each third guide wheel 502 is coaxially rotatably assembled 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 dipping 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 dipping tank 100 and can slide longitudinally along the dipping tank 100. Second sliding blocks 505 are respectively assembled at both ends of the third transverse shaft 501. Each second sliding block 505 is slidably assembled on the 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. A second operating handwheel 507 is assembled at the upper end of the second vertical lead screw 506. In this embodiment, an adapter seat 508 is installed on the third transverse shaft 501. One end of a longitudinal adjustment lead screw 509 is threadedly connected to the adapter seat 508. A third operating handwheel 510 is assembled at the other end of the longitudinal adjustment lead screw 509, and the longitudinal adjustment lead screw 509 is threadedly connected to the dipping tank 100. The working principle and advantages of this embodiment are as follows: The wire 800 is guided by the corresponding fourth guide wheel 404 to the corresponding third guide wheel 502. By operating the second operating handwheel 507, the second vertical lead screw 506 drives the third transverse shaft 501 to move vertically through the second sliding block 505. At the same time, by rotating the third operating handwheel 510 in cooperation, the relative position of the wheel set type lead-out mechanism 500 and the dipping tank 100 in the horizontal direction can be adjusted, so that the angle of the wire 800 guiding to the third guide wheel 502 can be adjusted, ensuring that wires 800 with different radial lengths can be smoothly and smoothly led into the third guide wheel 502. By adjusting the relative position of the wheel set type lead-out mechanism 500 and the dipping tank 100 in the horizontal direction in this embodiment, the length of the wire 800 between the fourth guide wheel and the third guide wheel can be adjusted, thereby changing the length of the wire 800 extending obliquely out of the paint liquid, ensuring that the thickness and uniformity of the insulating paint layer on the surface of the wire 800 with the corresponding radial length reach the predetermined range.

[0043] As a preferred embodiment of the present invention, as Figure 9 、 10As shown in the figure, the visual inspection mechanism 600 includes two horizontally installed seats 603, which are arranged vertically and stagger each other. A plurality of image collectors 604 are installed at intervals on each horizontally installed seat 603, and these image collectors 604 are arranged in one-to-one correspondence with a plurality of wires 800. In this embodiment, two longitudinal adjustment seats 601 are provided. The two horizontally installed seats 603 are arranged between the two longitudinal adjustment seats 601. Two longitudinal sliding rails 602 are respectively provided on the end faces of the two longitudinal adjustment seats 601 close to each other. The two longitudinal sliding rails 602 are arranged vertically on the longitudinal adjustment seats 601. Both ends of each horizontally installed seat 603 are respectively slidably connected to the corresponding two longitudinal sliding rails 602, so as to achieve the purpose of slidably connecting the horizontally installed seat 603 with the two longitudinal adjustment seats 601. A third vertical lead screw 606 is threadedly connected to each longitudinal adjustment seat 601. The lower end of the third vertical lead screw 606 is rotatably connected to a fixed seat 605. The upper end of the third vertical lead screw 606 is equipped with a fourth operating handwheel 607. The fixed seat 605 is installed on the support frame. In this embodiment, the horizontal distance between the two horizontally installed seats 603 can be adjusted, and the vertical distance between the two horizontally installed seats 603 can also be adjusted to ensure that the image collector 604 can accurately collect the thickness and break points of the outer insulating paint layer of the corresponding wire 800, etc.

[0044] As a preferred embodiment of the present invention, as Figures 11-15 shown, the paint replenishing type pre-drying mechanism 700 includes an assembly body 701. Connecting plates 727 are detachably connected to both sides of the assembly sleeve 711 respectively, and each connecting plate 727 is connected to the corresponding longitudinal adjustment seat 601. In this embodiment, a plurality of angle-adjustable paint replenishing units are constructed on the assembly body 701. These angle-adjustable paint replenishing units are arranged at intervals in the horizontal direction of the assembly body 701. A swirl type pre-drying unit with the same number as the angle-adjustable paint replenishing units is arranged in the assembly body 701. Each swirl type pre-drying unit is arranged at the outlet end of the corresponding angle-adjustable paint replenishing unit. Each wire 800 sequentially passes through the corresponding angle-adjustable paint replenishing unit and the swirl type pre-drying unit. The angle-adjustable paint replenishing unit adjusts the spraying angle. After the adjustment is completed, the paint liquid is atomized and sprayed onto the part of the wire 800 to be replenished with paint. After the paint replenishment is completed, hot air swirls out from the swirl type pre-drying unit and spirally blows on the outer peripheral surface of the wire 800, so that the insulating paint layer is pre-dried on the outer surface of the wire.

A fixed end cover 707 is arranged at the large-diameter end of the atomizing cover 702. The fixed end cover 707 is sleeved outside the fitting sleeve 711. The fixed end cover 707 is rotatably connected to the fitting sleeve 711, and the fixed end cover 707 is detachably connected to the assembly 701 through a plurality of fastening bolts. The angle adjustment unit of this embodiment includes a driving motor 713, a driving pulley 714, a driven pulley 712 and a timing belt 715. The driving motor 713 is assembled on the assembly 701. The driving pulley 714 is coaxially assembled on the output shaft of the driving motor 713. The driven pulley 712 is coaxially assembled outside the fitting sleeve 711. The timing belt 715 is drivingly connected to the driving pulley 714 and the driven pulley 712. In this embodiment, a paint inlet branch pipe 721 and a liquid collecting branch pipe 709 are installed on the assembly 701. The paint inlet branch pipe 721 and the liquid collecting branch pipe 709 are respectively communicated with the atomizing chamber 705 and the annular liquid collecting groove 708. A paint inlet control valve 722 is installed on the paint inlet branch pipe 721. Moreover, the paint inlet branch pipe 721 is communicated with the paint inlet main pipe 723. The paint inlet main pipe 723 is communicated with a paint storage bucket for containing paint liquid through a pressure pump; the liquid collecting branch pipe 709 is communicated with the liquid collecting main pipe 710. The outlet end of the liquid collecting main pipe 710 is communicated with a liquid collecting tank.The working principle and advantages of this embodiment are as follows: The wire 800 moves from the large-diameter end towards the small-diameter end along the axis of the first conduction channel 703. The driving motor 713 drives the atomizing cover 702 to rotate by a certain angle through the transmission of the belt pulley, so that the atomizing holes 704 on the atomizing cover 702 face the part of the wire 800 to be painted. At this time, the paint liquid is pumped into the atomizing chamber 705, and then atomized by the atomizing holes 704 and sprayed onto the part of the wire 800 to be painted, thereby ensuring the uniformity of the surface of the insulating paint layer. Moreover, since the atomizing cover 702 is in a horn shape, when the atomized paint liquid enters the first conduction channel 703, the atomized paint liquid inclines and faces away from the swirl-type pre-drying unit, thereby preventing the atomized paint liquid from entering the swirl-type pre-drying unit; the excess paint liquid entering the first conduction channel 703 will gradually gather at the large-diameter end of the atomizing cover 702, and then enter the annular liquid collecting tank 708 through the liquid guiding port 706, and finally enter the liquid collecting tank through the liquid collecting branch pipe 709 and the liquid collecting main pipe 710.

[0046] As a preferred embodiment of the present invention, as Figures 13-15 shown, the swirl-type pre-drying unit includes an air guiding cover 716. The diameter of the air guiding cover 716 increases along the conveying direction of the wire 800. A connecting flange 719 extending radially outward is formed at the large-diameter end of the air guiding cover 716. The connecting flange 719 is detachably connected to the assembly 701 through a plurality of connecting bolts. A second conduction channel 717 is formed inside the air guiding cover 716. An air guiding cavity 720 is formed between the air guiding cover 716 and the assembly 701. A plurality of swirl air outlet ports 718 are evenly arranged on the circumferential wall of the air guiding cover 716 along its circumferential direction. The second conduction channel 717 communicates with the air guiding cavity 720 through these swirl air outlet ports 718. An air inlet branch pipe 724 is installed on the assembly 701. The air inlet branch pipe 724 communicates with the air guiding cavity 720. An air inlet control valve 725 is installed on the air inlet branch pipe 724. Moreover, the air inlet branch pipe 724 communicates with the air inlet main pipe 726. The clean hot air enters the air inlet main pipe 726, the air inlet branch pipe 724 and the air guiding cavity 720 in sequence, and then swirls into the second conduction channel 717 through each swirl air outlet port 718. And since the air guiding cover 716 is in a horn-shaped structure, after the hot air enters the second conduction channel 717, it moves in a spiral shape away from the angle-adjustable paint filling unit, thereby preventing the hot air from entering the angle-adjustable paint filling unit and affecting the atomizing paint filling operation; and the swirling hot air can fully cover the outer peripheral surface of the wire 800, ensuring that the insulating paint layer on the outer peripheral surface of the wire 800 is pre-dried synchronously and sufficiently. And the paint inlet control valve 722 and the air inlet control valve 725 in this embodiment are both solenoid valves, so as to facilitate the independent opening of a certain paint inlet branch pipe 721 or air inlet branch pipe 724.

[0047] The present invention discloses a usage method of the above-mentioned intelligent enameling machine based on visual sensing detection, including the following steps:

[0048] Step 1. Immerse multiple wires 800 in the dip painting tank 100, the vision inspection mechanism 600, and the paint replenishing type pre-drying mechanism 700 in sequence.

[0049] Step 2. Control the vision inspection mechanism 600 to continuously inspect each wire 800 and inspect 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 wire 800 is too thin, control the paint replenishing type pre-drying mechanism 700 to replenish the paint at the too-thin part of the paint layer on the surface of the wire 800. After the replenishment is completed, perform pre-drying treatment.

[0051] Step 4. When it is detected that the overall thickness of the paint layer on the surface of the wire 800 is too thin or too thick, control the position of the adjustable guiding mechanism 400 and / or the wheel group type guiding-out mechanism 500 in the dip painting tank 100, and adjust the length of the wire 800 immersed in the dip painting tank 100.

[0052] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
