Description

Technical Field

[0001] The present invention relates to the technical field of enameled round aluminum wire production, and in particular 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 wire, enameled round aluminum wire has the significant advantages of low density, light weight and low cost, making it the preferred electrical connection material in photovoltaic inverters. Especially in large-scale production, the use of enameled round aluminum wire can effectively reduce raw material costs and bring significant economic benefits. Efficient and automated enameled round aluminum wire production lines not only improve production efficiency, but also ensure the quality control of the aluminum wire, guaranteeing its reliability in high-precision equipment such as inverters.

[0003] For example, a production line for enameled round aluminum wire suitable for energy storage inverters, with publication number CN119400522A, adopts a splash coating mechanism and an annular blowing mechanism, combined with the horizontal linear movement of the aluminum wire, to achieve dynamic spraying of the aluminum wire on the production line for paint coating. The uniform blowing of the annular airflow can avoid the problem of excessive or uneven paint accumulation due to bubbles, particles or other surface defects in certain parts of the aluminum wire. However, during the period from dynamic spraying to solidification, the excess insulating paint on the surface of the aluminum wire flows to the bottom under the action of gravity and then drips. It is difficult to carry out all-round elimination coating or separation treatment of the paint that has accumulated into water droplets and cannot drip by only using the annular airflow blowing method, so that the paint after solidification still has a certain uneven coating thickness.

[0011] Preferably, a plurality of movable blocks are slidably installed on the bottom of the annular plate, and an L-shaped rod is fixedly connected to the movable block, a ⺁-shaped track that slides with the corresponding L-shaped rod is fixedly connected to the annular outer wall of the annular pushing seat, and a limit block that slides with the L-shaped rod is fixedly connected to the rotating sleeve.

[0012] Preferably, a filter is rotatably connected to one side of the connecting port, and an isosceles triangle drainage block is connected to the side of the filter close to the auxiliary sleeve through a support rod, and the asymmetric side of the isosceles triangle drainage block conflicts with the side of the connecting port located at the rotating connection point of the filter.

[0013] Preferably, a drying cylinder is fixedly mounted on the mounting frame and located above the paint storage cylinder, and an annular heating net is provided inside the drying cylinder, and two sets of guide wheels are mounted on the mounting frame.

[0014] The beneficial effects of the present invention are as follows:

[0015] The present invention performs a paint dipping treatment on the aluminum wire in a paint storage cylinder by moving the aluminum wire vertically and upward, which can promote the continuous and dead-angle-free wrapping coating of the insulating paint on the aluminum wire, thereby efficiently preparing enameled round aluminum wire.

[0033] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-8 As shown, in this embodiment, an enameled round aluminum wire production line suitable for photovoltaic inverters includes a mounting frame 1 and a uniform paint dipping mechanism 2 provided on the mounting frame 1. The uniform paint dipping mechanism 2 includes a paint storage cylinder 21 fixedly mounted 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 via bolts. An elastic hollow plug 24 with a conical structure extending to the outside of the auxiliary sleeve 22 is fixed to the top of the hollow column 23.

[0035] The hollow hole of the elastic hollow plug 24 is naturally smaller than the diameter of the corresponding aluminum wire. After the aluminum wire is passed through the elastic hollow plug 24, the elastic contraction of the material of the elastic hollow plug 24 seals the gap between the aluminum wire and the elastic hollow plug 24. The upward movement of the aluminum wire prevents leakage of the insulating paint in the paint storage cylinder 21.

[0036] The detachable connection between the hollow column 23 and the auxiliary sleeve 22 enables replacement of the elastic hollow plug 24 with different internal apertures, enabling the production of enameled round aluminum wires of different sizes, further expanding the scope of application;

[0037] The aluminum wire is passed through the elastic hollow plug 24 into the paint storage barrel 21 and is dipped in paint by a vertical ascending movement. This enables the insulating paint to be applied to the aluminum wire in a continuous, wrapping manner without dead angles, thereby efficiently preparing the enameled round aluminum wire. Furthermore, the excess insulating paint on the surface of the coated aluminum wire is caused to flow back to the paint storage barrel 21 by a synchronous vertical drop in all directions, thereby preventing the excess insulating paint from flowing to one side of the aluminum wire and then dripping, resulting in uneven coating thickness.

[0038] The paint storage barrel 21 is provided with a cleaning and straightening mechanism 3, which includes a rotating sleeve 31 rotatably connected to the bottom of the outer wall of the paint storage barrel 21. Two sets of U-shaped frames 1 32 and two sets of U-shaped frames 2 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 1 32.

[0039] The two sets of U-shaped frames 32 move relative to each other, carrying multiple straightening rollers 34 to clamp the aluminum wire, and then straighten the moving aluminum wire. Combined with the rotation of the rotating sleeve 31 carrying the U-shaped frame 32, all-round straightening of the aluminum wire before dipping is achieved to avoid local bending of the aluminum wire and affecting the consistency of the synchronous vertical descending speed of excess insulating paint after coating, further improving the high-quality processing of round aluminum wire by this enameled round aluminum wire production line, and preventing the gap between the aluminum wire and the elastic hollow plug 24 from being effectively sealed, resulting in leakage of insulating paint. An annular push seat 35 is rotatably installed on the annular outer wall of the rotating sleeve 31.

[0040] Guide pins 36 are fixedly connected to both the U-shaped frame 1 32 and the U-shaped frame 2 33. An arc-shaped guide groove 37 slidably connected to the corresponding guide pin 36 is provided on the annular push seat 35. A mounting cavity is provided on the annular push seat 35. An electric push rod 38 is hinged between one side of the mounting cavity and the rotating sleeve 31. The piston rod of the electric push rod 38 contracts or extends, driving the annular push seat 35 to deflect. Combined with the guidance of the arc-shaped guide groove 37 and the guide pin 36, the multiple U-shaped frames 1 32 and the U-shaped frame 2 33 are prompted to move synchronously relative to or away from each other.

[0041] A cleaning brush 39 is fixedly connected to the top of the second U-shaped frame 33. Two sets of cleaning brushes 39 move relative to the second U-shaped frame 33 to contact the straightened aluminum wire and clean impurities on its surface to prevent impurities from affecting the coating effect of the insulating paint on the aluminum wire and significantly increasing the impurity content inside the insulating paint. A Y-shaped limiting plate 310 is fixedly connected to the bottom. The two sets of Y-shaped limiting plates 310 move relative to the second U-shaped frame 33 to perform a centering limit treatment on the aluminum wire to prevent the aluminum wire from shaking during movement.

[0042] The auxiliary sleeve 22 is rotatably connected to an auxiliary ring on the outside. A linkage rod 311 is hinged between the top of the U-shaped frame 32 and the auxiliary ring. The rotational connection between the auxiliary ring and the auxiliary sleeve 22 prevents the U-shaped frame 32 from rotating in conjunction with the linkage rod 311, which in turn causes the auxiliary sleeve 22 to rotate and thus causes the aluminum wire to generate a twisting force.

[0043] Through the relative movement of the U-shaped frame 32, combined with the linkage rod 311, the auxiliary sleeve 22 is pushed to rise in the paint storage tube 21, thereby raising the height of the elastic hollow plug head 24. When the U-shaped frame 32 moves away, the bottom of the auxiliary sleeve 22 is pushed out from the rotating sleeve 31, increasing the disassembly space for the hollow column 23, thereby improving the convenience of replacing the elastic hollow plug head 24.

[0044] The straightening roller 34 is tilted, and the middle part of the straightening roller 34 is concave. The special arrangement of the straightening roller 34 is used to increase the contact area between the straightening roller 34 and the aluminum wire, and does not cause rotational twisting force on the aluminum wire when the straightening roller 34 rotates.

[0045] A motor 25 is installed on the outer wall of the paint storage tube 21 by bolts, and a gear 26 is installed on the output shaft of the motor 25. A gear ring 312 meshing with the gear 26 is installed on the rotating sleeve 31. The annular push seat 35 rotates, causing the two sets of U-shaped frames 32 to move relative to each other, carrying multiple inclined straightening rollers 34 to clamp the aluminum wire, and then the gear 26 is driven to rotate by the motor 25. The meshing gear 26 and the gear ring 312 drive the rotating sleeve 31 to rotate, thereby performing circumferential straightening treatment on the moving aluminum wire.

[0046] A drying drum 11 is fixedly mounted on the mounting frame 1 and located above the paint storage cylinder 21. An annular heating net is provided inside the drying drum 11. Two sets of guide wheels 12 are installed on the mounting frame 1. After the aluminum wire is guided by the lower guide wheels 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. After that, it passes through the paint storage cylinder 21 and enters the drying drum 11. The coated enameled round aluminum wire enters the drying drum 11.

[0047] The annular heating network inside the drying cylinder 11 is electrically heated to solidify the wire, and then guided to the next processing step by the upper guide wheel 12. By arranging multiple groups of drying cylinders 11 and paint storage cylinders 21 on the mounting frame 1, multiple enameled round aluminum wires can be processed synchronously, thereby improving the processing efficiency of the entire production line.

[0048] Example 2: Please refer to Figure 3-Figure 7 、 Figure 9 and Figure 10 As shown, in this embodiment, a temporary storage cavity 27 is fixedly connected to the outer wall of the paint storage cylinder 21, and a matching piston plate 28 slides inside the temporary storage cavity 27. An annular plate 29 is provided at the bottom of the temporary storage cavity 27, and a connecting rod is fixedly connected between the annular plate 29 and the piston plate 28 to seal and slide with the temporary storage cavity 27. A communication port 210 is opened between the temporary storage cavity 27 and the paint storage cylinder 21 and below the piston plate 28.

[0049] The piston plate 28 moves downward in the temporary storage cavity 27, discharging the insulating paint in the temporary storage cavity 27 into the paint storage tube 21 through the connecting port 210, thereby submerging the elastic hollow plug 24 with the aluminum wire passed through it, causing the insulating paint to wrap and coat the aluminum wire. The piston plate 28 moves upward in the temporary storage cavity 27, and the temporary storage cavity 27 extracts the insulating paint above the auxiliary sleeve 22 in the paint storage tube 21, thereby avoiding the problem that the insulating paint above the auxiliary sleeve 22 will be discharged through the auxiliary sleeve 22 during the replacement of the elastic hollow plug 24.

[0050] A plurality of movable blocks are slidably mounted on the bottom of the annular plate 29, and L-shaped rods 211 are fixedly connected to the movable blocks. The arrangement of the movable blocks and their sliding mounting with the annular plate 29 prevent interference with the rotation of the rotating sleeve 31. A V-shaped track 212 is fixedly connected to the annular outer wall of the annular push seat 35 and slidably engages with the corresponding L-shaped rods 211.

[0051] During the deflection of the annular push seat 35 carrying the ⺁-shaped track 212, the ⺁-shaped track 212 guides the L-shaped rod 211, prompting the annular plate 29 to combine with the connecting rod to drive the piston plate 28 to move downward or upward. A limit block is fixed to the rotating sleeve 31 and slides with the L-shaped rod 211 to limit the translation of the L-shaped rod 211 following the annular push seat 35.

[0052] A filter screen 213 is rotatably connected to one side of the communication port 210, and an isosceles triangle drainage block 214 is connected to the side of the filter screen 213 near the auxiliary sleeve 22 via a support rod. The asymmetric side of the isosceles triangle drainage block 214 interferes with the side of the communication port 210 at the rotational connection point of the filter screen 213.

[0053] A torsion spring is installed between the rotating connection point of the filter 213 and the communication port 210 to reset the filter 213 after it is opened, thereby improving the interception effect of impurities during the discharge of the insulating paint from the temporary storage chamber 27. A discharge port is opened on one side of the bottom of the temporary storage chamber 27, and a valve is installed in the discharge port to discharge impurities accumulated inside.

[0054] During the extraction process of the insulating paint from the paint storage barrel 21 by the temporary storage chamber 27, the communication port 210 is partially blocked by the isosceles triangle drainage block 214. This causes the insulating paint to move, pushing the isosceles triangle drainage block 214 and the filter screen 213 to deflect, causing a small amount of impurities that follow the aluminum wire into the paint storage barrel 21 to enter the temporary storage chamber 27.

[0055] When the insulating paint in the temporary storage cavity 27 is discharged into the paint storage tube 21 through the connecting port 210, the impurities in the insulating paint are filtered through the filter 213 in the connecting port 210 to prevent the impurities from flowing back into the paint storage tube 21 and affecting the coating effect. In the process of movement, the insulating paint pushes the isosceles triangle drainage block 214, one side of which conflicts with the connecting port 210, thereby strengthening the closed state of the filter 213 and enhancing the impurity interception effect.

[0056] Example 3: Please refer to Figures 1-10 As shown, the present invention also proposes a method for using an enameled round aluminum wire production line suitable for photovoltaic inverters, comprising the following steps:

[0057] Step 1: After being guided by 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 passes through the paint storage cylinder 21 and enters the drying cylinder 11, and is finally guided by the upper guide wheel 12 to enter the next processing step;

[0058] Step 2: The piston rod of the electric push rod 38 contracts, driving the annular push seat 35 to rotate. Combined with the guidance of the arc-shaped guide groove 37 and the guide pin 36, the multiple U-shaped frames 32 and 33 are prompted to move relative to each other. The two sets of Y-shaped limit plates 310 move relative to each other, performing a center-limiting treatment on the aluminum wire. The multiple inclined straightening rollers 34 clamp the aluminum wire. The motor 25 drives the gear 26 to rotate. The meshing gear 26 and the gear ring 312 drive the rotating sleeve 31 to rotate, performing a circumferential straightening treatment on the moving aluminum wire. The two sets of cleaning brushes 39 contact the straightened aluminum wire and clean impurities on its surface to prevent impurities from affecting the coating effect of the insulating paint on the aluminum wire and significantly increasing the impurity content inside the insulating paint.

[0059] Step 3: Through the relative movement of the U-shaped frame 1 32, the auxiliary sleeve 22 is pushed upward in the paint storage barrel 21 in combination with the linkage rod 311, thereby raising the height of the elastic hollow plug 24; and during the rotation of the annular push seat 35, the L-shaped rod 211 is guided by the ⺁-shaped track 212, prompting the annular plate 29 to combine with the connecting rod to drive the piston plate 28 to move downward, and the insulating paint in the temporary storage cavity 27 is discharged into the paint storage barrel 21 through the connecting port 210, thereby submerging the elastic hollow plug 24 with the aluminum wire passed through it, prompting the insulating paint to wrap the aluminum wire in a coating process. During the process of the insulating paint being discharged into the paint storage barrel 21 through the connecting port 210, impurities in the insulating paint are filtered by the filter screen 213 in the connecting port 210 to prevent the impurities from flowing back into the paint storage barrel 21 and affecting the coating effect;

[0060] Step 4: After the aluminum wire passes through the elastic hollow plug 24, it comes into contact with 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 the aluminum wire to form an enameled round aluminum wire. During the vertical upward movement of the enameled round aluminum wire, the excess insulating paint on its outer wall falls vertically and synchronously in all directions and flows back to the paint storage cylinder 21, eliminating the uneven coating thickness caused by the excess insulating paint flowing to a certain part of the aluminum wire. The coated enameled round aluminum wire enters the drying cylinder 11 and is heated by the annular heating network inside the drying cylinder 11 to be cured.

[0061] Step 5: When the coating process of the current enameled round aluminum wire or the processing of enameled round aluminum wires of different diameters is completed, the piston rod of the electric push rod 38 is extended, driving the annular push seat 35 to rotate in the opposite direction, and the multiple U-shaped frames 1 32 and U-shaped frame 2 33 move away from each other, prompting the bottom of the auxiliary sleeve 22 to be pushed out from the rotating sleeve 31, and the temporary storage cavity 27 to extract the insulating paint above the auxiliary sleeve 22 in the paint storage tube 21, and in the extraction process, the isosceles triangle drainage block 214 is used to partially block the connecting port 210, prompting the insulating paint to push the isosceles triangle drainage block 214 and the filter screen 213 to deflect during the movement of the insulating paint, causing a small amount of impurities that follow the aluminum wire into the paint storage tube 21 to enter the temporary storage cavity 27, remove the hollow column 23 and replace the corresponding elastic hollow plug 24, and repeat the above process.

[0062] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
