[0027] Preferably, in this embodiment, the etching liquid spraying device includes a storage tank 14, a connecting pipe 15, a water distribution plate 16 and a spray head 17. The storage tank 14 is installed at the top end of the shell 1 near the inlet 2. The connecting pipe 15 is installed at the bottom end of the storage tank 14. The water distribution plate 16 is installed at the bottom end of the connecting pipe 15 and penetrates the top wall of the shell 1. The bottom wall of the water distribution plate 16 is provided with a plurality of spray heads 17 arranged in a rectangular array. First, the etching liquid of a specific formula is stored in the storage tank 14 located at the top end of the shell 1 near the inlet 2. The design of the storage tank 14 ensures sufficient capacity to support long-term continuous operation. When the aluminum-based copper-clad plate enters the etching area, the etching liquid is transported from the bottom of the storage tank 14 to the water distribution plate 16 through the connecting pipe 15. The connecting pipe 15 ensures that the etching liquid can flow smoothly and continuously to the spraying position. After the etching liquid reaches the water distribution plate 16, it is uniformly sprayed onto the surface of the passing aluminum-based copper-clad plate through the plurality of spray heads 17 arranged in a rectangular array on the bottom wall of the water distribution plate 16. This design allows the etching liquid to cover the entire surface of the plate, ensuring consistency and uniformity in the etching process. The etching liquid sprayed on the aluminum-based copper-clad plate chemically reacts with the unwanted copper layer, removing the specified portion of the copper layer and forming the desired circuit pattern. Through the design of the water distribution plate 16 and the spray heads 17 arranged in a rectangular array, the etching liquid can be uniformly distributed on the entire surface of the plate, ensuring consistency and precision in etching, and reducing quality problems caused by local etching unevenness.

[0028] Preferably, in this embodiment, the back wall of the shell 1 is provided with a filter box 18. The top end of the filter box 18 is provided with a circulation pipe 19. The output end of the circulation pipe 19 is connected to the storage tank 14. The outer wall of the circulation pipe 19 is provided with a circulation pump 20. When the aluminum-based copper-clad plate passes through the etching area, the etching liquid is uniformly sprayed onto the surface of the plate through the spray heads 17 on the water distribution plate 16, the connecting pipe 15 and the storage tank 14 for etching treatment. The etched liquid (containing residual etching liquid and copper particles and other impurities falling from the plate) falls into the bottom of the shell 1 and is guided into the filter box 18 installed on the back wall of the shell 1. In this process, particulate matter is filtered out. The etching liquid that has undergone preliminary filtration is re-pumped back into the storage tank 14 through the circulation pump 20 along the circulation pipe 19. The circulation pump 20 ensures that the etching liquid can overcome gravity and pipe resistance to flow smoothly back. During or after the etching liquid flows back to the storage tank 14, new etching agents or solution components can be added as needed to maintain the optimal working state of the etching liquid, ensuring etching efficiency and quality. Through the circulation system, the etching liquid can be reused, greatly reducing the demand for fresh etching liquid and lowering production costs. Since the etching liquid can be quickly recovered and reused, the time required to prepare new etching liquid is reduced, improving the overall efficiency of the production line.

The blower 21 is installed on one end of the top wall of the housing 1 near the discharge port 3. The air outlet end of the blower 21 is connected to the air heater 22. Two sets of air supply pipes 23 are installed at the air outlet end of the air heater 22. The output ends of the two sets of air supply pipes 23 extend through the side wall of the housing 1 and are connected to the U-shaped frame 24 inside the housing 1. The air jets 25 are installed on the inner side walls at the top and bottom of the U-shaped frame 24. The blower 21 is installed on one end of the top wall of the housing 1 near the discharge port 3, responsible for providing continuous and sufficient airflow. The blower 21 sucks external air into the system. The air outlet end of the blower 21 is connected to the air heater 22. The air is heated to the appropriate temperature when passing through the heater, ensuring that the subsequent sprayed air can effectively evaporate the moisture on the surface of the aluminum-based copper-clad plate. The heated air is guided to the inside of the housing 1 through the two sets of air supply pipes 23 and extends to the U-shaped frame 24. The output ends of each set of air supply pipes 23 are connected to one U-shaped frame 24, ensuring that hot air can cover the upper and lower surfaces of the plate. The air jets 25 are installed on the inner side walls at the top and bottom of the U-shaped frame 24. These air jets 25 uniformly spray hot air onto the aluminum-based copper-clad plate, effectively drying the surface of the plate. This design ensures uniform distribution of heat and airflow, avoiding the problem of local overheating or insufficient drying. Due to the combination of high-efficiency blower 21 and air heater 22, a large amount of hot air can be quickly generated, accelerating the evaporation process of the moisture on the surface of the aluminum-based copper-clad plate and improving production efficiency.

[0030] Preferably, in this embodiment, a first baffle 26 is installed between the cleaning device and the etching liquid spraying device. A first opening 27 is formed in the middle of the first baffle 26. The first baffle 26 effectively separates the etching area from the cleaning area, avoiding direct contact or mixing between the etching liquid and the cleaning water. This helps to prevent the water quality during cleaning from being contaminated by the etching liquid, ensuring the cleaning effect, while also reducing harmful chemical reactions that may occur due to the mixing of the two liquids.

[0031] Preferably, in this embodiment, a second baffle plate 28 is installed between the drying device and the cleaning device, a second opening 29 is formed in the middle of the second baffle plate 28, and two groups of cotton rollers 30 are symmetrically and rotatably installed in the second opening 29, when the aluminum-based copper-clad plate enters the drying area from the cleaning area, the two groups of cotton rollers 30 in the second opening 29 can effectively wipe off most of the residual water on the surface of the plate, which not only reduces the burden of the subsequent drying process, but also improves the overall drying efficiency, the cotton rollers 30 can absorb and block the excess cleaning liquid from entering the drying area with the plate, avoiding the problem of cleaning liquid polluting the drying area, maintaining the professionalism and independence of the environment in each processing stage, reducing the amount of water entering the drying device helps to protect the drying equipment from water vapor erosion, thereby prolonging the service life of the equipment and reducing maintenance costs.

[0032] Preferably, in this embodiment, support legs 31 are installed at the bottom corners of the shell 1, which provide a solid foundation and ensure good stability and balance of the entire device.

[0033] Preferably, in this embodiment, a water outlet pipe 32 is installed below the cleaning device on the outer side wall of the shell 1, and a valve 33 is installed on the water outlet pipe 32, the installation of the water outlet pipe 32 can directly discharge the wastewater generated during the cleaning process from the equipment, avoiding the problem of internal water accumulation, keeping the equipment clean, preventing corrosion or other damage caused by long-term water accumulation, and by installing the valve 33 on the water outlet pipe 32, the time and speed of drainage can be flexibly controlled according to actual needs, which not only helps to arrange timely drainage according to the production process, but also avoids unnecessary waste of water resources.
