Description

Technical Field

[0001] The present invention relates to the technical field of enameled copper-aluminum flat wires, and particularly to an intelligent production device for enameled copper-aluminum flat wires used in photovoltaic inverters. Background Art

[0002] A photovoltaic inverter is a key component in a photovoltaic system. Its main function is to convert direct current (DC) generated by solar panels into alternating current (AC) so that it can be used in a household or commercial power grid. Enameled copper-aluminum flat wires are required for the windings of photovoltaic inverters.

[0003] Enameled copper-aluminum flat wire is a commonly used electromagnetic wire, mainly applied to the windings of various electrical equipment. Its manufacturing process involves extruding or drawing and annealing an oxygen-free copper rod or an electrician's round aluminum rod through a specific die to form the required wire shape. Subsequently, according to different temperature resistance grade requirements, the wire is coated with the corresponding insulating paint.

[0004] Coating the enameled copper-aluminum flat wire with insulating paint is an important step in the enameled copper-aluminum flat wire production line. The existing common painting methods are immersion method, brushing method, and spray coating method respectively. However, the immersion method requires a large paint tank, and in order to prevent the insulating paint from stratifying due to long-term stillness, additional stirring equipment needs to be installed to stir it, resulting in increased costs and inconvenient maintenance; for the brushing method, it is difficult to ensure the uniformity and consistency of the paint layer by manual operation, which is suitable for small-batch production and has low efficiency for large-batch production; for the spray coating method, the utilization rate of the paint material is relatively low during the spraying process, and a large amount of paint material will become overspray, which needs to be recycled. A good ventilation and paint material recovery system are required to prevent the paint material from volatilizing and causing harm to the environment and operators. Therefore, an intelligent production device for enameled copper-aluminum flat wires used in photovoltaic inverters is proposed to solve the above problems. Summary of the Invention

Detailed implementation manners

[0032] 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.

[0033] Please refer to Figures 1-9 , an intelligent production device for enameled copper-aluminum flat wire used in a photovoltaic inverter, including a paint storage cylinder 1. An internally movable paint dipping cylinder 2 is provided inside the paint storage cylinder 1. Connecting plates 3 are provided on both the left and right sides of the paint dipping cylinder 2. The connecting plates 3 are circular, and both sides of the paint storage cylinder 1 wrap the two connecting plates 3 respectively. The connecting plates 3 are movably connected to both sides of the paint storage cylinder 1. A feeding assembly 4 is provided on the right connecting plate 3, and a discharging assembly 5 is provided on the left connecting plate 3. Fixing frames 6 are installed on the separated sides of the two connecting plates 3. A driving gear 7 is fixedly connected to the surface of the paint storage cylinder 1, and a driving member 8 for driving the driving gear 7 to work is installed on the fixing frame 6.

[0034] Among them, the driving member 8 includes a motor 801 fixedly installed on the surface of the fixing frame 6. A driving gear 802 is fixedly installed on the output shaft of the motor 801, and the driving gear 802 meshes with the driving gear 7.

[0035] The motor 801 drives the driving gear 802 to rotate. The driving gear 802 meshes with the driving gear 7, so that the paint storage cylinder 1 can be driven to rotate through the driving gear 7, stirring and recycling the insulating paint inside the paint storage cylinder 1.

[0036] The feeding assembly 4 includes a lead wire cylinder 401 fixedly connected to the connecting plate 3. The lead wire cylinder 401 is trumpet-shaped, and the caliber size on the right side of the lead wire cylinder 401 is larger than the caliber size on the left side of the lead wire cylinder 401. A cleaning brush plate 402 is fixedly connected to the inner wall of the lead wire cylinder 401. A feeding hole 403 is opened in the center of the cleaning brush plate 402. The feeding hole 403 and the wire passing port 10 are on the same horizontal line.

[0037] The enameled flat wire passes through the lead wire cylinder 401 and passes through the inside of the feeding hole 403. When the enameled flat wire moves through the traction device on the production line, the cleaning brush plate 402 fits with the enameled flat wire, and impurities on the surface of the moving enameled flat wire will be removed, improving the subsequent coating effect.

[0038] Four partitions 11 are fixedly connected to the inner wall of the paint storage cylinder 1. The four partitions 11 are used to divide the cavity between the paint storage cylinder 1 and the paint dipping cylinder 2 into four independent cavities. The four partitions 11 are in contact with the outside of the paint dipping cylinder 2. Vent holes 12 are opened on two of the upper and lower partitions 11. A hydrophobic membrane 13 is arranged on the inner wall of the vent hole 12. The hydrophobic membrane 13 is a polytetrafluoroethylene hydrophobic membrane. An opening 14 is opened on the right side of the paint storage cylinder 1. The opening 14 corresponds to the cavity formed by the two partitions 11 with the hydrophobic membrane 13 installed. Control valves 15 are installed at the top and bottom of the paint storage cylinder 1. The control valves 15 are electric valves.

[0039] Drain holes 9 are opened at the top and bottom of the paint dipping cylinder 2, and the inner cavity of the paint dipping cylinder 2 is rectangular. Wire passing ports 10 are opened on the two connecting plates 3. The wire passing ports 10 are close to the inner bottom wall of the cavity of the paint dipping cylinder 2. The cross-section of the drain hole 9 is funnel-shaped. The number of drain holes 9 is several and they are evenly distributed at the top and bottom of the paint dipping cylinder 2. The number of drain holes 9 at the top and bottom is the same.

[0040] The inside of the paint storage cylinder 1 is divided into four cavities by the four partitions 11. The control valves 15 pour insulating paint into the top and bottom cavities of the paint storage cylinder 1. The insulating paint in the top cavity will flow downward due to gravity. The drain hole 9 at the top is above the flat wire, so the top of the flat wire will be dip-coated, changing the flow direction of the insulating paint. As the insulating paint flows, because the position of the wire passing port 10 is close to the inner bottom wall of the cavity of the paint dipping cylinder 2, the gap between the bottom of the flat wire passing through the wire passing port 10 and the inner bottom wall of the cavity is small. The small gap will indirectly affect the flow rate of the insulating paint discharged from the drain hole 9 below, causing a small amount of accumulation of the insulating paint at the bottom of the cavity of the paint dipping cylinder 2, so that the insulating paint can just cover the bottom of the flat wire for dip-coating, ensuring that the surface of the flat wire can be fully coated.

[0041] Since level sensors are provided in both the top and bottom cavities of the paint storage cylinder 1, and the upper level sensor is always in operation while the lower level sensor stops working. When the insulating paint in the upper cavity flows to the preset level, the level sensor emits a signal, causing the motor 801 to drive the paint storage cylinder 1 to rotate by 180 degrees, swapping the positions of the upper and lower cavities. Since the lower cavity had collected insulating paint through the paint discharge hole 9 before, after flipping, the insulating paint in this cavity is discharged through the paint discharge hole 9 by gravity. This process is repeated to coat the flat wire.

[0042] It should be noted that a hydrophobic membrane 13 is provided on the partition 11. When the paint storage cylinder 1 is flipped, to ensure normal air pressure in the cavity and that the inflow rate of the insulating paint is not affected by air pressure, while isolating the insulating paint through the hydrophobic membrane 13, the gas in the cavity is connected to the outside, ensuring the flow of air inside and outside, preventing any impact on the inflow rate of the insulating paint and indirectly affecting the dipping effect.

[0043] The discharge assembly 5 includes a connecting cylinder 501 fixedly connected to the connecting plate 3. A scraping die 502 is provided inside the connecting cylinder 501. The scraping die 502 fits with the connecting cylinder 501. A limiting post 503 is fixedly connected to the surface of the scraping die 502. A limiting rod 504 is sleeved on the surface of the limiting post 503. The limiting rod 504 extends outside the connecting cylinder 501. The limiting rod 504 and the connecting cylinder 501 are fixed by bolts. The limiting rod 504 is L-shaped, and a limiting hole adapted to the limiting post 503 is provided on the limiting rod 504. The limiting post 503 is connected to the limiting rod 504 through the limiting hole.

[0044] After the flat wire is dip-coated, it first passes through the scraping die 502. The scraping die 502 will scrape off the excess insulating paint on the flat wire to ensure uniform insulating paint on the flat wire. In actual production, different requirements exist for the thickness of the insulating paint on the flat wire, and the scraping die 502 needs to be replaced. By loosening the bolts, the limiting rod 504 can be driven to take the scraping die 502 out of the connecting cylinder 501. Since the limiting rod 504 is sleeved with the limiting post 503, it is convenient to remove the limiting rod 504 and the scraping die 502 for replacing the scraping die 502 with different specifications.

[0045] The working principle of the intelligent production device for enameled copper-aluminum flat wire used in the photovoltaic inverter is as follows: The enameled flat wire passes through the lead wire cylinder 401 and into the interior of the feed hole 403. When the enameled flat wire moves through the traction device on the production line, the cleaning brush plate 402 fits against the enameled flat wire and removes the impurities on the surface of the moving enameled flat wire. The interior of the paint storage cylinder 1 is divided into four cavities by four partitions 11. The control valve 15 fills the top and bottom cavities of the paint storage cylinder 1 with insulating paint. The insulating paint in the top cavity flows downward due to gravity, and the paint discharge hole 9 at the top is located above the flat wire, so the top of the flat wire is dip-coated. This changes the flow direction of the insulating paint. As the insulating paint flows, since the position of the wire passing hole 10 is close to the inner bottom wall of the cavity of the paint dipping cylinder 2, the gap between the bottom of the flat wire passing through the wire passing hole 10 and the inner bottom wall of the cavity is small. This small gap indirectly affects the flow rate of the insulating paint discharged from the lower paint discharge hole 9, causing a small amount of accumulation of the insulating paint at the bottom of the cavity of the paint dipping cylinder 2, so that the insulating paint just covers the bottom of the flat wire for dip-coating, ensuring that the surface of the flat wire can be fully coated. After the flat wire is dip-coated, it first passes through the scraping die 502, which scrapes off the excess insulating paint on the flat wire to ensure that the insulating paint on the flat wire is uniform. In the actual production process, different requirements are placed on the thickness of the insulating paint on the flat wire, and the scraping die 502 needs to be replaced. By loosening the bolts, the limiting rod 504 can drive the scraping die 502 out of the connecting cylinder 501. Since the limiting rod 504 is sleeved with the limiting column 503, it is convenient to remove the limiting rod 504 and the scraping die 502 for replacement with scraping dies 502 of different specifications.

[0046] In summary, by intermittently flipping the paint storage cylinder 1, the insulating paint in the upper and lower cavities can be stirred, effectively preventing stratification. And the paint dipping work is completed inside the paint storage cylinder 1, effectively preventing the insulating paint from leaking and volatilizing to the outside, causing pollution to the working environment. And the excess insulating paint falls into the lower cavity. After the paint storage cylinder 1 is flipped, the recycled insulating paint can be directly used, saving the process of recycling and then refilling.
