Description

Technical Field

[0002] Copper foil is made of copper and other metals in a certain proportion. There are two types of copper foil: 90% foil and 88% foil, which means the copper content is 90% and 88%. Copper foil has low surface oxygen characteristics and can be attached to various substrates, such as metals, insulating materials, etc. It has a wide temperature range. The product is widely used in industrial calculators, communication equipment, QA equipment, lithium-ion batteries, civilian TV sets, video recorders, CD players, copiers, telephones, air conditioners, automotive electronic components, game consoles, etc.; copper foil is a metal product, and surface oxidation is inevitable. When oxidized, the surface of the copper foil changes color, which will reduce the electrical conductivity and thermal conductivity of the copper foil. Therefore, the copper foil should be ground offline first, and then cleaned to remove surface dirt. The cleaning water should be filtered after use so that it can be recycled to save water resources. As the impurities on the filter increase, the water permeability gradually deteriorates, resulting in increased water pressure, which will not only damage the water pump but also cause filtration stagnation. The roughness of the grinding tool directly affects the quality of the copper foil. At present, the quality of the copper foil cannot be tested after polishing.

[0027] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0028] Step 1: The water pump 6 draws out the cleaning water in the water tank 3 under its own suction force, and reaches the filter bag filter 4 through the valve body 71. After the filter bag filter 4 and the filter element filter 5 filter the cleaning water, the cleaning water is sent to the tee 11, and the tee 11 performs diversion. The nozzle 10 sprays water into the cleaning box 9. The copper foil moves in the cleaning box 9 under the rolling of the guide roller 13. The cleaning water rinses the copper foil, and then the cleaning water flows back to the water tank 3, so as to circulate and rinse the copper foil; Step 2, when the impurities in the bag filter 4 and the filter element filter 5 gradually increase, the water permeability gradually deteriorates. Once the bag filter 4 and the filter element filter 5 are saturated, the filtration flow rate decreases, the water pressure in the valve body 71 gradually increases, and the water pressure pushes the right side of the piston 75. At the same time, the pull rod 76 drives the first rack 77 to move right, allowing the first gear 78 to rotate counterclockwise until the pin 711 is on the right side of the first gear 78, the tension spring 713 changes the tilting direction, and the tension of the tension spring 713 pulls the first gear 78 to rotate counterclockwise, and the piston 75 moves to the right side of the joint 74. The cleaning water flows back to the water tank 3 through the joint 74, and the valve body 71 is depressurized to prevent the water pump 6 from being overloaded and damaged. The first rack 77 triggers the travel switch 714, causing the buzzer 72 to sound an alarm, reminding the staff that the bag filter 4 or the filter element filter 5 needs to be cleaned; Step three, unscrew the handle 159 from the positioning blind hole 152, release the positioning of the second gear 157, adjust the height of the phased array probe 155 according to the width of the copper foil, drive the second gear 157 to rotate clockwise or counterclockwise through the handle 159, and move the lifting plate 154 downward or upward until the handle 159 is at the corresponding positioning blind hole 152, send the handle 159 into the positioning blind hole 152, and the phased array probe 155 reaches the specified height, changing the flaw detection range of the phased array probe 155, so as to detect the flaws of copper foils of different sizes and prevent unqualified copper foils from being used.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
