Description

Technical Field

[0001] This utility model belongs to the field of dip coating tooling technology, and relates to a dip coating tooling for processing photovoltaic brackets using a large single basket coating machine. Background Technology

[0002] As international markets increasingly demand higher standards for corrosion protection of photovoltaic (PV) bracket surfaces, and as the international market gains widespread acceptance and application of chromium-free zinc-aluminum coating technology, domestic manufacturers are gradually phasing out electroplating processes and switching to zinc-aluminum coating surface treatment processes, which offer better corrosion protection and higher added value. This aims to meet the high-end demands of the international market, address the corrosion issues of PV bracket components in complex maritime environments, increase the market share of high-end PV brackets, and improve company profitability. The previous conventional disordered dip-coating + spraying process had the following drawbacks: First, the PV brackets were heavy and prone to sliding and impacts during immersion, resulting in severe coating damage and reduced corrosion protection. Second, the conventional dip-coating process resulted in significant coating thickness variation and inconsistent appearance and overall corrosion resistance. Third, the combined dip-coating + spraying process required frequent loading and unloading, leading to high personnel costs and labor intensity. Fourth, the complex bracket structure meant that coatings could not effectively adhere to blind spots, resulting in thinner coatings and higher corrosion risks. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a dip-coating fixture for processing photovoltaic brackets using a large single-basket coating machine. This fixture solves the problems of photovoltaic brackets being heavy, prone to sliding and bumping during immersion when placed haphazardly, resulting in severe coating damage and reduced anti-corrosion performance; the large variation and wide range of coating thickness in conventional dip-coating processes, leading to inconsistent appearance and overall corrosion resistance; the need for frequent loading and unloading of parts in a combined dip-coating and spraying process, resulting in high labor costs and intensity; and the complex bracket structure, where coatings cannot effectively adhere to blind spots, resulting in thinner coatings and higher corrosion risks in these areas.

[0004] The objective of this utility model can be achieved through the following technical solutions: A dip-coating fixture for processing photovoltaic brackets using a large single-basket coating machine is characterized by comprising a large bottom ring, a small bottom ring in the middle of the large bottom ring, the large bottom ring and the small bottom ring being fixedly connected by a plurality of reinforcing ribs, a plurality of support columns being uniformly fixedly connected to the large bottom ring, a first support ring being fixedly connected to the support columns, a plurality of uprights being fixedly connected to the small bottom ring, a second support ring being fixedly connected to the uprights, and a plurality of limiting posts being uniformly fixedly connected to the second support ring.

[0005] In the above-mentioned dip coating fixture for processing photovoltaic brackets in large single basket coating machines, a metal ring is fixedly connected to the top of the support column.

[0006] In the above-mentioned dip coating fixture for processing photovoltaic brackets using a large single basket coating machine, the height of the first support ring is higher than that of the second support ring.

[0007] In the above-mentioned dip coating fixture for processing photovoltaic brackets using a large single basket coating machine, the number of support columns is twelve.

[0008] In the above-mentioned dip coating fixture for processing photovoltaic brackets using a large single basket coating machine, the number of limiting posts is ten.

[0009] Compared with the prior art, the present invention has the following advantages: This tooling design cleverly utilizes the structural characteristics of the workpiece, fixing it vertically. This allows for processing a large number of units at a time, and the simple tooling structure minimizes additional solution loss and significantly reduces raw material costs. The orderly fixing of the photovoltaic bracket prevents slippage and collisions during the dipping process, ensuring no damage to the coating, better corrosion resistance, and significantly improved coating thickness dispersion and variation. The consistent coating appearance and overall corrosion resistance are also enhanced. Using this tooling for dipping eliminates the need for spraying, reducing the need for frequent loading and unloading; a single loading and unloading process yields the finished product, significantly reducing labor costs and intensity. Compared to spraying, single-process efficiency is significantly improved. Furthermore, using this tooling for dipping throughout the entire process completely eliminates the risk of thin coatings in blind spots and insufficient corrosion resistance associated with spraying.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0013] like Figure 1 As shown, A dip-coating fixture for processing photovoltaic brackets using a large single-basket coating machine is characterized by comprising a large bottom ring 2, a small bottom ring 3 in the middle of the large bottom ring 2, the large bottom ring 2 and the small bottom ring 3 being fixedly connected by a plurality of reinforcing ribs 4, a plurality of support columns 5 being uniformly fixedly connected to the large bottom ring 2, a first support ring 6 being fixedly connected to the support column 5, a plurality of upright columns 7 being fixedly connected to the small bottom ring 3, a second support ring 8 being fixedly connected to the upright column 7, and a plurality of limiting columns 9 being uniformly fixedly connected to the second support ring 8.

[0014] In this embodiment, the fixture is suitable for dip coating of photovoltaic brackets on a large single-basket coating machine. During use, the central cavity of the workpiece is placed on the limiting post 9. At this time, the second support ring 8 provides support precisely at the groove of the workpiece, and the upper end of the workpiece abuts against the first support ring 6 for limiting. This fixture design cleverly utilizes the structural characteristics of the workpiece to fix it vertically. It can process a large number of items at a time, and the fixture design is simple, thus minimizing additional solution loss and significantly reducing raw material costs. The orderly fixing of the photovoltaic bracket prevents it from sliding or bumping during dip coating, ensuring no damage to the coating, better corrosion resistance, and significantly improved coating thickness dispersion and variation. The coating appearance and overall corrosion resistance are consistent. Using this fixture eliminates the spraying process, eliminating the need for frequent loading and unloading; a single loading and unloading is sufficient for the finished product, significantly reducing labor costs and labor intensity. Compared to spraying, single-process efficiency is significantly improved. The use of this fixture for the entire process completely eliminates the risk of thin coatings in blind spots and insufficient corrosion resistance associated with spraying.
