[0002] Aluminum materials used in electronics have high requirements for surface quality. The production of such products generally goes through two processes of stretch bending and leveling, and cleaning, followed by trimming and straightening to obtain the finished product. Due to the special surface quality requirements of electronic aluminum materials, the original equipment uses caustic solution with ultra-high conductivity (conductivity 55 us / cm) in the cleaning process, and the production speed is controlled at ≤ 50 m / min, resulting in low production efficiency, seriously restricting the equipment production capacity, and at the same time, the equipment energy consumption cost is relatively large. In the actual production process, when the aluminum material finished product passes through the cleaning equipment, there are still water mark or caustic solution mark defects on the head strip, which cannot be used normally by customers and need to be returned, thus causing relatively large economic losses.

[0014] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0015] As Figure 1 shown, a dual-mode production device for electronic aluminum materials includes an uncoiler, a flattening roller, a circular shear 1, a high-pressure cleaning tank 2, an alkali cleaning tank 3, a high-pressure rinsing tank 4, a high-pressure rinsing squeezing roller 5, a low-pressure rinsing tank 6, a low-pressure rinsing squeezing roller 7, a drying oven, a straightening machine, and a coiler arranged in sequence; an outer guide roller device for conducting aluminum materials is provided above the area between the high-pressure cleaning tank and the low-pressure rinsing tank. The uncoiler, flattening roller, circular shear, drying oven, straightening machine, and coiler all belong to the prior art, and among them, the uncoiler, flattening roller, drying oven, straightening machine, and coiler are not described in Figure 1As shown. The caustic washing tank and the rinsing tank of the original production line are removed, and a new cleaning system is designed, fabricated and installed, namely a high-pressure cleaning tank, a caustic washing tank, and high- and low-pressure rinsing tanks. High-pressure hot water cleaning is added before caustic washing to achieve the first-pass cleaning of aluminum materials for electronics; by adding an external guide roller device above the cleaning system, a production process is realized in which the finished product does not need to pass through the cleaning system directly after the second-pass finished product trimming, reducing the production energy consumption of the cleaning system while also solving the water mark defect at the head of the finished product, improving the surface quality and cleaning efficiency of the product, increasing the production efficiency of electronic aluminum materials, reducing production costs, expanding the equipment production capacity, and increasing the finished product rate and product revenue.

[0016] There are two lines for the aluminum materials to achieve dual-mode production. In the first-pass cleaning, the cleaning mode is adopted, and the aluminum materials pass through the high-pressure cleaning tank, the caustic washing tank, and the high- and low-pressure rinsing tanks for cleaning; in the second-pass finished product processing, the aluminum materials pass through the upper external guide roller device without cleaning, avoiding water mark or caustic solution mark defects in the head strip.

[0017] In this embodiment, a number of upper guide rollers 8 and a number of lower guide rollers 9 for the aluminum materials to pass through in a reciprocating serpentine manner up and down are provided in the caustic washing tank 3; a number of groups of caustic washing pipes 10 are provided on the transmission path of the aluminum materials in the caustic washing tank. Each group of caustic washing pipes consists of two and is distributed on both sides of the aluminum materials. Caustic washing nozzles are arranged at intervals on the caustic washing pipes. A caustic washing squeezing roller 13 is provided on the outlet side in the caustic washing tank. The guide rollers in the caustic washing tank are made of corrosion-resistant nitrile rubber material, and each guide roller in the caustic washing tank is driven by a reduction motor, which can reduce the risk of scratch.

[0018] In this embodiment, two high-pressure cleaning spray pipes 11 are provided in the high-pressure cleaning tank and are distributed on the upper and lower sides of the aluminum material 20. A high-pressure cleaning squeezing roller 12 is provided on the outlet side in the high-pressure cleaning tank.

[0019] In this embodiment, two groups of high-pressure rinsing spray pipes 14 are provided in the high-pressure rinsing tank, and each group of high-pressure rinsing spray pipes consists of two and is distributed on the upper and lower sides of the aluminum material; a number of low-pressure rinsing spray pipes 15 are provided in the low-pressure rinsing tank, and each group of low-pressure rinsing spray pipes consists of two and is distributed on the upper and lower sides of the aluminum material.

[0020] The caustic washing tank is changed to a reciprocating serpentine threading method (longitudinal threading method) and a large-flow caustic washing pump is used for cleaning, greatly lengthening the length of the aluminum materials in the caustic washing tank, so that the length of the aluminum materials in the caustic washing tank is ≥12 meters. The conductivity of the caustic solution for caustic washing is 20 - 30 us / cm, and the caustic solution adopts the HL305 model solution; the low-pressure rinsing tank uses a large-flow low-pressure pump for hot water flushing. Each water tank has an independent heating function, and the water temperature is controlled at 62 ± 3°C. Squeezing rollers are installed at the outlets of each water tank to prevent the water on the strip surface from mixing into other tank bodies and ensure the cleaning quality.

[0021] In this embodiment, a lye circulation pipe communicating with each lye washing pipe is connected to the bottom of the lye washing tank. A lye circulation pump and a lye filter are provided on the lye circulation pipe. The lye washing tank is further connected with a lye supply pipe. A liquid level sensor, a temperature sensor, a heater and a conductivity sensor are arranged in the lye washing tank, realizing the recycling of lye, the automatic supply of lye, and the real-time monitoring of the conductivity, liquid level and temperature of the lye.

[0022] In this embodiment, a water tank is further included. Return pipes leading to the water tank are connected to the bottoms of the high-pressure cleaning tank, the high-pressure rinsing tank and the low-pressure rinsing tank. The water tank is connected with a water supply pipe. A water circulation pump and a water filter are provided on the water supply pipe. A temperature sensor and a heater are arranged in the water tank. The water supply pipe is connected with a water supply branch pipe communicating with the high-pressure cleaning spray pipe, the high-pressure rinsing spray pipe and the low-pressure rinsing spray pipe, realizing the recycling of water and the real-time monitoring of the water temperature.

[0023] In this embodiment, the outer guide roller device includes an inlet guide roller 16, an intermediate guide roller 17 and an outlet guide roller 18. A pressure roller 19 is arranged above the inlet guide roller and the outlet guide pipe. Realize the production that the finished product trimming and threading in the second pass do not pass through the cleaning system. The pressure roller is installed above the inlet guide roller and the outlet guide roller. When switching to the cleaning mode, the pressure roller can be pressed down, and then after the strip is cut, it is not necessary to pull out the strip between the inlet guide roller and the outlet guide pipe, realizing the rapid threading during the switching of the dual-mode production.

[0024] When converting from the cleaning pass to the finished product pass, the operator presses down the high-pressure cleaning squeezing roller and the low-pressure rinsing squeezing roller, and then cuts the aluminum materials in front of and behind the two groups of squeezing rollers. The strip between the rollers does not need to be pulled out and is used for the next threading. When converting from the finished product pass to the cleaning pass, the operator presses down the pressure roller above the inlet guide roller and the outlet guide roller, and then cuts the aluminum materials in front of and behind the two groups of guide rollers. The strip between the rollers also does not need to be pulled out and is used for the next threading.

[0025] This embodiment is implemented on a 1300mm aluminum material tension leveling and bending equipment. The equipment has a high matching degree in terms of design width, thickness and electronic aluminum usage. At the same time, it has functions of trimming, cleaning and straightening by itself. Therefore, the technical transformation cost is low, the cycle is short, and the effect is quick.

[0026] Three operation interfaces, namely the lye washing mode, the water washing mode and the non-cleaning mode, are added to the WINCC screen of the production device control system. The operator can perform one-key switching according to the production process information of the incoming materials. The background program has closed-loop control over each pump group, fan and drying heater of the cleaning system. When the non-cleaning mode is selected in the finished product pass, it is automatically turned off, and it runs automatically in the cleaning mode. The mode switching is efficient, accurate and convenient. The specific operation control process is as Figure 2 shown.

[0027] Production method of the dual-mode production device for electronic aluminum materials of the utility model, including the following steps:

[0028] (1) Aluminum for electronics in the cleaning pass: After the aluminum material is flattened and the edges are cut by a circular shear, it is successively subjected to high-pressure cleaning, alkali cleaning, high-pressure rinsing, and low-pressure rinsing, and then dried and wound on a coiler.

[0029] (2) Aluminum for electronics in the finished product pass: After the aluminum material is flattened and the edges are cut by a circular shear, it passes through the upper external guide roller device, and then is straightened to form a finished product and wound on a coiler.

[0030] The aluminum material completed in the cleaning pass is annealed in an annealing furnace and then subjected to the production of the finished product pass.

[0031] In this embodiment, in step (1), the number of meters of the aluminum material in the alkali cleaning tank ≥ 12 m, and the conductivity of the alkali solution for alkali cleaning is 20 - 30 us / cm; the temperatures of high-pressure cleaning, alkali cleaning, high-pressure rinsing, and low-pressure rinsing are 62 ± 3 °C, the water pressure for high-pressure cleaning and high-pressure rinsing is 6.5 - 7.5 MPa, and the water pressure for low-pressure rinsing is 0.3 - 0.4 MPa.

[0032] The following preliminary work needs to be carried out before the normal start-up production of the aluminum for electronics in step (1) above:

[0033] Step S1: According to the production task, take a coil from the coil storage and thread it through the machine.

[0034] Step S2: Manually thread the aluminum material through the high-pressure cleaning tank, alkali cleaning tank, high- and low-pressure rinsing tanks, pass through each squeezing roller and then enter the drying box, and then to the coiler. At this time, the straightening machine is in the raised state and does not participate in production.

[0035] Step S3: Input the coil information, set parameters such as tension, elongation, and speed on the WINCC screen, and at the same time select the alkali cleaning mode, and each heating pump and heater operate automatically.

[0036] Step S4: Set the conductivity of the alkali solution tank, wait for the water temperature and the temperature of the drying box, and start the pulling head after the automatic operation conditions of the equipment are met.

[0037] Step S5: Check the surface quality after starting the pulling head. After there is no abnormality, put a sleeve on the coiler and then start normal production.

[0038] The following preliminary work needs to be carried out before the normal start-up production of the aluminum for electronics in step (2) above:

[0039] Step S1: According to the production task, take a coil from the coil storage.

[0040] Step S2: When the production in the cleaning pass reaches the end of the strip, slowly pull the end of the strip behind the circular shear at a low speed.

[0041] Step S3: Lower the high-pressure cleaning and squeezing roller and the low-pressure rinsing and squeezing roller;

[0042] Step S4: Start the threading operation. After the strip passes through the circular shear, it passes through the upper inlet guide roller, intermediate guide roller, and outlet guide roller, and then reaches the position of the low-pressure rinsing and squeezing roller;

[0043] Step S5: After the strip behind the low-pressure rinsing and squeezing roller is cut and re-glued, the aluminum material passes through the straightening machine and then reaches the coiler. At this time, the low-pressure rinsing and squeezing roller is in the raised state and neither it nor the drying oven is involved in the operation;

[0044] Step S6: Switch the WINCC screen to the non-cleaning mode;

[0045] Step S7: Turn on the machine and check the surface quality of the draw head. After there is no abnormality, put the sleeve on the coiler, and then start the normal production.

[0046] By adding a cleaning system to the aluminum material stretch bending and straightening equipment, the dual-mode production function of aluminum materials for electronics is realized. This method promotes the development and optimization of the production process of aluminum materials for electronics, improves the cleaning quality and production efficiency of products, reduces the return loss caused by alkali marks or water marks, saves production energy consumption, achieves the goal of improving quality and increasing efficiency, and has been well applied on site.
