Description

Technical Field

[0001] The present invention relates to the technical field of enameled round aluminum wire production, and particularly to an enameled round aluminum wire production line suitable for photovoltaic inverters. Background Art

[0002] In the field of photovoltaic inverter manufacturing, the selection of electrical connection materials is crucial. Compared with traditional copper wires, enameled round aluminum wires have significant advantages such as low density, light weight, and low cost, making them the preferred electrical connection materials in photovoltaic inverters. Especially in large-scale production, using enameled round aluminum wires can effectively reduce raw material costs and bring significant economic benefits. Moreover, an efficient and automated enameled round aluminum wire production line not only improves production efficiency but also ensures the quality control of aluminum wires, guaranteeing their reliability in high-precision equipment such as inverters.

[0003] For example, an enameled round aluminum wire production line suitable for energy storage inverters with the publication number CN119400522A adopts a splashing mechanism and an annular blowing mechanism, and combines the horizontal linear movement of the aluminum wire to achieve the paint coating treatment by dynamically spraying the aluminum wire of the production line. After that, through the uniform blowing of the annular air flow, although it can avoid the problem of excessive or uneven paint accumulation at some positions of the aluminum wire due to bubbles, particles, or other surface defects, however, during the period from dynamic spraying to curing, the excess insulating paint on the surface of the aluminum wire flows to its bottom and accumulates and drips under the action of gravity. Only by using the method of annular air flow blowing, it is difficult to perform a full-range elimination coating or separation treatment on the paint that has gathered into a water droplet shape and cannot drip, resulting in a certain problem of uneven coating thickness of the cured paint.

[0011] Preferably, a filter screen is rotatably connected to one side inside the communication port, and an isosceles triangular drainage block is connected to the side of the filter screen close to the auxiliary sleeve through a support rod. The asymmetrical side of the isosceles triangular drainage block abuts against the side of the communication port where the filter screen is rotatably connected.

[0012] Preferably, a drying cylinder is fixedly installed above the paint storage cylinder on the mounting frame, and an annular heating network is arranged inside the drying cylinder. Two groups of guide wheels are installed on the mounting frame.

[0013] The beneficial effects of the present invention are as follows: In the present invention, the aluminum wire is subjected to dipping treatment in a vertical upward movement manner in the paint storage cylinder, which can promote the continuous and dead-angle-free wrapping coating treatment of the aluminum wire with the insulating paint material.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Embodiment 1: Please refer to Figures 1 - 8 As shown, in this embodiment, an enamelled round aluminum wire production line applicable to a photovoltaic inverter includes a mounting frame 1 and a uniform material dipping paint mechanism 2 provided on the mounting frame 1. The uniform material dipping paint mechanism 2 includes a paint storage cylinder 21 fixedly installed on the mounting frame 1, and an auxiliary sleeve 22 is slidably connected to the bottom of the paint storage cylinder 21. A hollow column 23 is installed inside the auxiliary sleeve 22 through bolts, and an elastic hollow plug 24 extending to the outside of the auxiliary sleeve 22 and having a conical structure is fixedly connected to the top of the hollow column 23; The hollow hole size of the elastic hollow plug 24 is smaller than the diameter size of the corresponding aluminum wire in the natural state. After the aluminum wire passes through the inside of the elastic hollow plug 24, due to the elastic contraction performance of the material of the elastic hollow plug 24 itself, the gap between the aluminum wire and the elastic hollow plug 24 is blocked, and in cooperation with the upward movement mode of the aluminum wire, the problem of leakage of the insulating paint in the paint storage cylinder 21 is avoided; The detachable connection between the hollow column 23 and the auxiliary sleeve 22 enables the replacement of the elastic hollow plug 24 with different inner diameters inside, and can realize the production of enamelled round aluminum wires of different sizes, further improving the scope of application; Thread the aluminum wire through the elastic hollow plug 24 into the paint storage cylinder 21, and adopt the upward movement in a vertical state for dipping treatment, which can promote the continuous and dead-angle-free wrapping coating treatment of the aluminum wire by the insulating paint. While efficiently preparing the enameled round aluminum wire, it can also make the excess insulating paint on the surface of the coated aluminum wire flow back to the paint storage cylinder 21 in a synchronous and vertical downward manner in all directions. Furthermore, it can avoid the problem of uneven coating thickness caused by the excess insulating paint flowing to one side of the aluminum wire, gathering first and then dripping. A cleaning and straightening mechanism 3 is provided on the paint storage cylinder 21. The cleaning and straightening mechanism 3 includes a rotating sleeve 31 rotatably connected to the bottom of the outer wall of the paint storage cylinder 21. Two groups of U-shaped frames 32 and two groups of U-shaped frames 33 are slidably connected inside the rotating sleeve 31. A plurality of straightening rollers 34 are rotatably installed on the opposite sides of the U-shaped frame 32. The two groups of U-shaped frames 32 move relatively, carrying a plurality of straightening rollers 34 to clamp the aluminum wire, and then straightening the moving aluminum wire. Combining with the rotation of the rotating sleeve 31 carrying the U-shaped frame 32, a comprehensive straightening treatment is carried out on the aluminum wire before dipping to avoid the problem that the local bending of the aluminum wire affects the consistency of the synchronous vertical downward speed of the excess insulating paint after coating, further improving the high-quality processing of the round aluminum wire by this enameled round aluminum wire production line, and preventing the problem that the gap between the aluminum wire and the elastic hollow plug 24 cannot be effectively sealed, resulting in the leakage of insulating paint. A ring-shaped pushing seat 35 is rotatably installed on the outer ring wall of the rotating sleeve 31.

[0018] Guide pins 36 are fixedly connected to both the U-shaped frame 32 and the U-shaped frame 33. An arc-shaped guide groove 37 slidably connected to the corresponding guide pins 36 is provided on the ring-shaped pushing seat 35. And an installation cavity is provided on the ring-shaped pushing seat 35. An electric push rod 38 is hinged between one side of the installation cavity and the rotating sleeve 31. When the piston rod of the electric push rod 38 contracts or extends, it drives the ring-shaped pushing seat 35 to deflect. Combining with the guidance of the arc-shaped guide groove 37 and the guide pins 36, it promotes the synchronous relative or separating movement of the plurality of U-shaped frames 32 and the U-shaped frames 33.

[0019] A cleaning brush 39 is fixedly connected to the top of the U-shaped frame 33. The two groups of cleaning brushes 39 move relatively with the U-shaped frame 33 and contact the straightened aluminum wire to clean the impurities on its surface, preventing the impurities from affecting the coating effect of the insulating paint on the aluminum wire and greatly increasing the impurity content inside the insulating paint. And a Y-shaped limiting plate 310 is fixedly connected to the bottom. The two groups of Y-shaped limiting plates 310 move relatively with the U-shaped frame 33 to perform centering limiting treatment on the aluminum wire, avoiding the problem of the aluminum wire shaking during movement. An auxiliary ring is rotatably connected to the outer side of the auxiliary sleeve 22. A linkage rod 311 is hinged between the top of the U-shaped frame 1 32 and the auxiliary ring. Through the rotatable connection between the auxiliary ring and the auxiliary sleeve 22, it is avoided that the U-shaped frame 1 32 rotates around and drives the auxiliary sleeve 22 to rotate through the linkage rod 311, thereby preventing the problem of generating a twisting force on the aluminum wire; Through the relative movement of the U-shaped frame 1 32, combined with the linkage rod 311 pushing the auxiliary sleeve 22 to move upward in the paint storage cylinder 21, the height of the elastic hollow plug 24 is lifted. When the U-shaped frame 1 32 moves away, the bottom of the auxiliary sleeve 22 is pushed out of the rotating sleeve 31, increasing the disassembly space for the hollow column 23 to improve the convenience of replacing the elastic hollow plug 24.

[0020] The straightening roller 34 is inclined, and the middle part of the straightening roller 34 is of a concave structure. Through the special setting of the straightening roller 34, it is used to increase the contact area between the straightening roller 34 and the aluminum wire, and when the straightening roller 34 rotates around, it will not cause the aluminum wire to generate a rotational twisting force; A motor 25 is installed on the outer side wall of the paint storage cylinder 21 through bolts, and a gear 26 is installed on the output shaft of the motor 25. A toothed ring 312 meshing with the gear 26 is installed on the rotating sleeve 31. The annular pushing seat 35 rotates, causing the two U-shaped frames 1 32 to move relatively, carrying multiple inclined straightening rollers 34 to clamp the aluminum wire. Then, the motor 25 is driven to rotate the gear 26, and the rotating sleeve 31 is driven to rotate through the meshing of the gear 26 and the toothed ring 312, performing a circumferential and comprehensive straightening treatment on the moving aluminum wire.

[0021] A drying cylinder 11 is fixedly installed on the mounting frame 1 and above the paint storage cylinder 21, and an annular heating network is arranged inside the drying cylinder 11. Two guide wheels 12 are installed on the mounting frame 1. After guiding the aluminum wire through the lower guide wheel 12, it passes through the rotating sleeve 31, the hollow column 23, and the elastic hollow plug 24 in sequence and enters the paint storage cylinder 21, then exits the paint storage cylinder 21 and enters the drying cylinder 11. The coated enameled round aluminum wire enters the drying cylinder 11; Through the energization and heating of the annular heating network inside the drying cylinder 11 for curing treatment, and then guided by the upper guide wheel 12 into the next processing step. By arranging multiple drying cylinders 11 and paint storage cylinders 21 on the mounting frame 1, it is used for synchronous processing of multiple enameled round aluminum wires, thereby improving the processing efficiency of the overall production line.

[0022] Embodiment 2: Please refer to Figures 3 - 7 、 Figure 9 And Figure 10As shown in the figure, in this embodiment, a temporary storage cavity 27 is fixedly connected to the outer wall of the paint storage cylinder 21. A piston plate 28 that fits is slidably arranged inside the temporary storage cavity 27. An annular plate 29 is arranged at the bottom of the temporary storage cavity 27. A connecting rod that is hermetically slidable in the temporary storage cavity 27 is fixedly connected between the annular plate 29 and the piston plate 28. A communication port 210 is opened between the temporary storage cavity 27 and the paint storage cylinder 21 and below the piston plate 28. When the piston plate 28 moves downward in the temporary storage cavity 27, the insulating paint material in the temporary storage cavity 27 is discharged into the paint storage cylinder 21 through the communication port 210, thereby submerging the elastic hollow plug 24 with the aluminum wire passing through it, and prompting the insulating paint material to perform a wrapping coating treatment on the aluminum wire. When the piston plate 28 moves upward in the temporary storage cavity 27, the temporary storage cavity 27 extracts the insulating paint material in the paint storage cylinder 21 above the auxiliary sleeve 22, avoiding the problem that the insulating paint material above the auxiliary sleeve 22 will be discharged through the auxiliary sleeve 22 during the replacement of the elastic hollow plug 24.

[0023] A plurality of movable blocks are slidably installed at the bottom of the annular plate 29, and an L-shaped rod 211 is fixedly connected to the movable blocks. The arrangement of the movable blocks and their sliding installation with the annular plate 29 avoid interfering with the rotation of the rotating sleeve 31. An L-shaped track 212 that slidably cooperates with the corresponding L-shaped rod 211 is fixedly connected to the annular outer wall of the annular pushing seat 35. During the deflection of the annular pushing seat 35 carrying the L-shaped track 212, through the guidance of the L-shaped track 212 on the L-shaped rod 211, the annular plate 29 drives the piston plate 28 to move downward or upward in combination with the connecting rod. A limiting block that slidably contacts the L-shaped rod 211 is fixedly connected to the rotating sleeve 31, which is used to limit the problem that the L-shaped rod 211 follows the annular pushing seat 35 to translate.

[0024] A filter screen 213 is rotatably connected to one side inside the communication port 210. An isosceles triangular drainage block 214 is connected to the side of the filter screen 213 close to the auxiliary sleeve 22 through a support rod. The non-symmetric side of the isosceles triangular drainage block 214 abuts against one side of the communication port 210 where the filter screen 213 is rotatably connected. A torsion spring is installed between the rotation connection point of the filter screen 213 and the communication port 210 for the reset process after the filter screen 213 is opened, thereby improving the interception effect of impurities during the discharge of the insulating paint material from the temporary storage cavity 27. A waste discharge port is opened on one side of the bottom of the temporary storage cavity 27, and a valve is provided in the waste discharge port for discharging the accumulated impurities inside. During the extraction of the insulating paint material in the paint storage cylinder 21 by the temporary storage cavity 27, by partially blocking the communication port 210 with the isosceles triangular drainage block 214, the insulating paint material moves to push the isosceles triangular drainage block 214 to carry the filter screen 213 to deflect during the movement, causing the impurities that enter the paint storage cylinder 21 in small amounts following the aluminum wire to enter the temporary storage cavity 27. When the insulating paint in the temporary storage cavity 27 is discharged into the paint storage cylinder 21 through the communication port 210, the filter screen 213 in the communication port 210 filters the impurities in the insulating paint to prevent the impurities from flowing back into the paint storage cylinder 21 and affecting the coating effect. During the movement of the insulating paint, the isosceles triangular drainage block 214 is pushed, and one side of it abuts against the communication port 210, thereby strengthening the closed state of the filter screen 213 and enhancing the impurity interception effect.

[0025] Embodiment 3: Please refer to Figures 1 - 10 As shown, the present invention also proposes a use method for an enameled round aluminum wire production line applicable to a photovoltaic inverter, including the following steps: Step 1: After guiding the aluminum wire through the lower guide wheel 12, the aluminum wire passes through the rotating sleeve 31, the hollow column 23, and the elastic hollow plug 24 in sequence and enters the paint storage cylinder 21, then exits from the paint storage cylinder 21 and enters the drying cylinder 11, and then is guided by the upper guide wheel 12 and enters the next processing step; Step 2: The piston rod of the electric push rod 38 contracts, driving the annular pushing seat 35 to rotate. With the guidance of the arc-shaped guiding groove 37 and the guiding pin 36, multiple U-shaped frames 32 and U-shaped frames 33 move relative to each other, and two groups of Y-shaped limiting plates 310 move relative to each other to perform centering and limiting treatment on the aluminum wire. Multiple obliquely arranged straightening rollers 34 clamp the aluminum wire. The motor 25 drives the gear 26 to rotate, and through the meshed gears 26 and the gear ring 312, the rotating sleeve 31 is driven to rotate to perform circumferential and comprehensive straightening treatment on the moving aluminum wire. Two groups of cleaning brushes 39 contact the straightened aluminum wire to clean the impurities on its surface, preventing the impurities from affecting the coating effect of the insulating paint on the aluminum wire and greatly increasing the impurity content inside the insulating paint; Step 3: Through the relative movement of the U-shaped frame 32, the auxiliary sleeve 22 is pushed to rise in the paint storage cylinder 21 by the linkage rod 311 to lift the height of the elastic hollow plug 24; during the rotation of the annular pushing seat 35, through the guidance of the ⺁-shaped track 212 on the L-shaped rod 211, the annular plate 29 drives the piston plate 28 to descend through the connecting rod, and the insulating paint in the temporary storage cavity 27 is discharged into the paint storage cylinder 21 through the communication port 210, thereby submerging the elastic hollow plug 24 with the aluminum wire passing through its interior, and enabling the insulating paint to perform a wrapped coating treatment on the aluminum wire. When the insulating paint is discharged into the paint storage cylinder 21 through the communication port 210, the filter screen 213 in the communication port 210 filters the impurities in the insulating paint to prevent the impurities from flowing back into the paint storage cylinder 21 and affecting the coating effect; Step Four: After the aluminum wire passes through the elastic hollow plug 24 and contacts the insulating paint in the paint storage cylinder 21, during the process of passing through the paint storage cylinder 21, the insulating paint continuously wraps and coats the aluminum wire to form an enameled round aluminum wire. During the vertically upward movement of the enameled round aluminum wire, the excess insulating paint on its outer wall vertically falls back to the paint storage cylinder 21 in all directions synchronously, eliminating the uneven coating thickness caused by the flow of the excess insulating paint to a certain part of the aluminum wire. The enameled round aluminum wire after coating enters the drying cylinder 11 and is cured by being heated through the annular heating network inside the drying cylinder 11. Step Five: When the coating process of the current enameled round aluminum wire is completed or when enameled round aluminum wires with different diameters are processed, the piston rod of the electric push rod 38 extends, driving the annular push seat 35 to rotate in the reverse direction. The plurality of U-shaped frames I 32 and the U-shaped frames II 33 move away from each other, causing the bottom of the auxiliary sleeve 22 to be pushed out of the rotating sleeve 31. The temporary storage cavity 27 extracts the insulating paint in the paint storage cylinder 21 above the auxiliary sleeve 22. During the extraction process, a part of the communication port 210 is blocked by the isosceles triangular drainage block 214, causing the insulating paint to push the isosceles triangular drainage block 214 to deflect with the filter screen 213 during movement, so that the impurities that enter the paint storage cylinder 21 following the aluminum wire in a small amount enter the temporary storage cavity 27. The hollow column 23 is disassembled and the corresponding elastic hollow plug 24 is replaced, and then the above process is repeated.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
