This improves circuit quality, resulting in a smoother, more even surface after film removal, enhancing circuit accuracy; improves signal transmission performance; removes impurities from the copper foil surface; protects the environment by removing photosensitive adhesive, reducing environmental pollution, and facilitating subsequent processing.

[0004] However, most companies use manual methods for unwrapping: the product to be unwrapped is first placed on the unwrapping rack, then the unwrapping rack is placed into the unwrapping tank for unwrapping. The unwrapping rack is manually shaken to ensure that the product is in full contact with the solution in the unwrapping tank, thereby achieving the purpose of unwrapping the product. However, manual operation is labor-intensive, easily causes employee fatigue, and production is risky. People in the field are actively researching to create an unwrapping production line to replace manual operation, thereby improving production efficiency and production safety. Utility Model Content

[0005] Therefore, it is necessary to address the problems of manual film removal, such as high workload, easy fatigue of workers, and production risks.

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Please see Figure 1 and Figure 2 This embodiment provides a film removal production line, which includes a conveyor line 120 composed of rollers and a chain drive mechanism. Along the conveying direction of the conveyor line 120, there are sequentially a primary film expansion cylinder 10, a secondary film expansion cylinder 20, a high-pressure spray film removal cylinder 30, a primary water washing cylinder 40, a secondary water washing cylinder 50, an ultrasonic immersion washing cylinder 60, a neutralization water washing cylinder 70, a circulating water washing cylinder 80, a moisture absorption device 90, a strong air drying device 100, and a hot air drying device 110. The conveyor line 120 conveys the product into each working cylinder at a uniform speed. The minimum speed of the conveyor line 120 is 0.2 m / min, and the maximum speed can be adjusted to 6 m / min. The speed is adjusted according to the film properties or size of the product to achieve the best film removal effect.

[0023] In this embodiment, the primary membrane expansion tank 10 and the secondary membrane expansion tank 20 use sodium hydroxide solution to perform two chemical reactions on the membrane on the product, causing the membrane to expand and making it easier to detach from the product. The primary membrane expansion tank 10 and the secondary membrane expansion tank 20 are equipped with multiple sets of solution nozzles symmetrically arranged on the upper and lower sides of the conveyor line 120, a solution storage tank, and a pump body connected to the multiple sets of solution nozzles through pipes to draw sodium hydroxide solution from the solution storage tank. It is also equipped with a device for pumping the sodium hydroxide solution in the primary membrane expansion tank 10 and the secondary membrane expansion tank 20 back into the container for recycling, or pumping it back into the solution storage tank for reuse.

[0024] In other embodiments, sodium hydroxide solution is placed in the primary membrane expansion tank 10 and the secondary membrane expansion tank 20. The product is conveyed at low speed through the conveyor line 120, immersing it in the primary and secondary membrane expansion tanks 10 and 20. During immersion, the sodium hydroxide solution chemically reacts with the membrane on the product, causing the membrane to expand. Immersion allows for more thorough contact with the membrane, improving the efficiency of the chemical reaction. Furthermore, immersion ensures that every part of the product is evenly affected by the sodium hydroxide solution, preventing localized areas from failing to expand sufficiently. This further ensures that the membrane on the product can be removed more easily and thoroughly, thus improving the film removal effect. Simultaneously, the immersion method allows for flexible adjustment of the immersion time and sodium hydroxide solution concentration according to the specific product and film removal requirements, meeting the film removal needs of different products.

[0025] After undergoing chemical reactions in the primary membrane expansion tank 10 and the secondary membrane expansion tank 20, the membrane attached to the product expands. Then, it is detached from the product by the high-pressure spray membrane removal tank 30. In this embodiment, the high-pressure spray membrane removal tank 30 is equipped with multiple sets of high-pressure nozzles, symmetrically arranged vertically on the conveyor line 120. The high-pressure nozzles use municipal water and are connected to a high-pressure pump via pipelines. The high-pressure pump is connected to a municipal water tank via pipelines. Wastewater from the high-pressure spray membrane removal tank 30 is discharged to a corresponding wastewater pool for treatment. The expanded membrane is then detached from the product via high-pressure spraying. The multiple sets of high-pressure nozzles further enhance the spraying effect, allowing the membrane to be washed off more quickly. Furthermore, a filter screen is installed inside the high-pressure spray membrane removal tank 30 to facilitate the separation of spray water and membrane for membrane collection. A waste membrane recycling bin is located on the side of the high-pressure spray membrane removal tank 30.

[0026] Because the film on some products is not easy to remove and remains attached to the product, in order to prevent products with film from entering the next station, an inspection station 130 is set up at the outlet of the high-pressure spray film removal cylinder 30. The inspection station 130 uses manual inspection to pick out products with film and remove them for secondary film removal.

[0027] To prevent sodium hydroxide solution residue from remaining on the product and to prevent it from corroding the product, thus ensuring product quality, a secondary washing tank 50 is installed. There are two secondary washing tanks 50, each equipped with multiple sets of nozzles that spray water using municipal water. These nozzles are symmetrically arranged on both sides of the conveyor line 120. The sodium hydroxide solution residue on the product surface is cleaned by the water spray. Drainage pipes are installed on the two secondary washing tanks 50 to discharge wastewater into corresponding wastewater pools.

[0028] Some products have different shapes, making them difficult to clean effectively, resulting in sodium hydroxide solution residue in inaccessible areas. To address this, an ultrasonic immersion tank 60 is installed. This tank effectively cleans areas inaccessible to the nozzle, preventing sodium hydroxide solution residue. In this embodiment, three ultrasonic immersion tanks 60 are provided. Each tank has its own independent water supply and drainage system, as well as an independent ultrasonic system. Adjacent tanks are separated by partitions to prevent water from entering. Each tank contains an ultrasonic water collection tray, connected to which the water supply and drainage systems are connected. The ultrasonic system performs ultrasonic cleaning on the products within the tray, and the drainage system discharges the wastewater from the tray into a corresponding wastewater pool.

[0029] To ensure that the sodium hydroxide solution remaining on the product surface does not corrode the product, after immersion cleaning in the ultrasonic immersion tank 60, the product passes through the neutralization water washing tank 70. The sodium hydroxide solution in the neutralization water washing tank 70 is neutralized by a weakly acidic solution. In this embodiment, the neutralization water washing tank 70 is equipped with multiple sets of nozzles, symmetrically arranged on both sides of the conveyor line 120. The nozzles are connected to a pump body via pipes, and the pump body is connected to a weakly acidic solution pool via pipes. The neutralization water washing tank 70 is equipped with a drainage system connected to the weakly acidic solution pool, allowing for the recycling of the weakly acidic solution. Alternatively, the drainage system can be connected to a corresponding wastewater pool.

[0030] After neutralization, the product needs to be cleaned again to remove the weakly acidic solution. For this purpose, a circulating water washing tank 80 is set up. The circulating water washing tank 80 uses municipal water to spray and clean the product. There are 3 circulating water washing tanks 80 along the conveying direction of the conveyor line 120. Each circulating water washing tank 80 is equipped with multiple sets of nozzles symmetrically arranged on the upper and lower sides of the conveyor line 120. Each circulating water washing tank 80 is also equipped with a drainage system to transport wastewater to the corresponding wastewater pool.

[0031] After cleaning, the product is sent out of the circulating water washing tank 80 by the conveyor line 120 and the water is absorbed by the water-absorbing device 90. In this embodiment, the water-absorbing device 90 includes water-absorbing cotton wrapped around the side of the roller and chain drive mechanism for absorbing water from the product surface. The water-absorbing cotton absorbs the water from the product surface so that the subsequent strong wind drying device 100 and hot air drying device 110 can effectively remove the water from the product surface.

[0032] In this embodiment, the high-powered air drying device 100 includes a circulating fan box, multiple air vents communicating with the inside of the circulating fan box, and a fan connected to the multiple air vents through pipes. The air vents are evenly arranged on the side of the circulating fan box facing the product. The fan delivers air to the air vents, and the air vents blow out strong air to dry the product that has passed through the high-powered air drying device 100, further removing moisture from the surface of the product.

[0033] In this embodiment, the hot air drying device 110 includes an oven, a circulating air duct, a fan device, and an electric heating element. The circulating air duct is connected to the oven, and the fan device sends the heat generated by the electric heating element into the circulating air duct, which then enters the oven to dry the product. The hot air drying device 110, combined with the previous strong wind drying device 100, forms a complete drying process, ensuring that the moisture on the surface of the product is completely removed. The dried product flows out through the conveyor line 120.

[0034] In summary, by introducing an automated film removal production line, the traditional manual film removal operation has been replaced, significantly reducing labor costs and greatly improving production efficiency. This production line, along the conveying direction of the roller and chain drive mechanism, sequentially includes a primary and secondary film expansion tank 20, a high-pressure spray film removal tank 30, a primary water washing tank 40, a secondary water washing tank 50, an ultrasonic immersion washing tank 60, a neutralization water washing tank 70, a circulating water washing tank 80, a moisture absorption device 90, a strong air drying device 100, and a hot air drying device 110. Employing a multi-stage cleaning and ultrasonic solution removal system, it effectively reduces the corrosiveness of the solution to the product, ensuring product quality.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
