Description

Technical Field

[0001] The invention relates to the technical field of ultra-thin molybdenum strip nickel plating, in particular to an ultra-thin molybdenum strip continuous nickel plating device and process. Background Art

[0002] Nickel plating of ultra-thin molybdenum strip is a process that coats the surface of ultra-thin molybdenum strip with a nickel coating. This process is primarily used to improve the corrosion resistance, surface hardness, and electrical conductivity of the molybdenum strip. Nickel plating processes typically include electroplating, chemical plating, and physical vapor deposition. Electroplating involves immersing the molybdenum strip in a nickel-containing electrolyte, forming a nickel film on the surface through an electrochemical reaction. Chemical plating deposits nickel on the surface of the molybdenum strip through a chemical reaction. Currently, ultra-thin molybdenum strips are usually nickel-plated inside a nickel plating tank. The ultra-thin molybdenum strips are pulled by a winding device to move inside the nickel plating tank. The nickel plating will adhere to the surface of the ultra-thin molybdenum strips during the movement. However, after the ultra-thin molybdenum strips are produced, some waste or impurities will adhere to the surface. The waste and impurities will increase the roughness of the surface of the ultra-thin molybdenum strips, which can easily lead to uneven plating during the nickel plating process. The coating will be too thick or too thin in some areas, affecting the overall quality. Summary of the Invention

[0013] Furthermore, a process for a continuous nickel plating device for ultra-thin molybdenum strips comprises the following steps: S1: The molybdenum belt is wound in a U shape inside the circular groove rod. When the winding device pulls the molybdenum belt to move, the molybdenum belt will move on the surface of the circular groove rod. The circular groove rod limits the molybdenum belt to prevent the molybdenum belt from slipping and deviating during movement.

[0014] The present invention has the following beneficial effects: The present invention adds the liquid required for the processing chamber into the interior of the storage box through the water inlet pipe, and the water pump transmits the corresponding liquid to the corresponding processing chamber through the bend pipe to clean the molybdenum strip, and places the molybdenum strip into the interior of the processing chamber through the through hole. The molybdenum strip is wound in a U shape inside the circular groove rod. When the winding device pulls the molybdenum strip to move, the molybdenum strip will move on the surface of the circular groove rod, and the molybdenum strip is limited by the circular groove rod to prevent the molybdenum strip from sliding and deviating during movement. A groove rod is provided inside the through hole to limit the molybdenum strip, further improving the stability of the molybdenum strip during movement. The molybdenum strip is supported and limited by the circular groove rod, so that the molybdenum strip is in a tensioned state when moving inside the processing chamber, and the molybdenum strip is prevented from stacking together and affecting the nickel plating effect. When the molybdenum strip is inside the ultrasonic degreasing chamber, the molybdenum strip is cleaned by ultrasonic waves, and the waste and impurities on the surface of the molybdenum strip are removed by ultrasonic waves. For cleaning, hydrogen peroxide is added to the inside of the oxidation chamber, and the hydrogen peroxide is used to remove the thick oxide layer on the surface of the molybdenum copper substrate. Potassium dichromate and sulfuric acid are added to the inside of the pickling chamber to increase the cleanliness of the molybdenum strip surface. Nickel plating liquid is added to the inside of the nickel plating chamber. When the molybdenum strip moves inside the nickel plating chamber, the nickel plating liquid will adhere to the surface of the molybdenum strip to complete the nickel plating treatment. After the surface of the molybdenum strip is cleaned, the bonding strength of the chrome plating layer and the molybdenum strip will be improved. When the molybdenum strip is cleaned inside the processing chamber, the electric push rod is started to push the linkage plate to move. When the linkage plate moves, the lifting frame is pushed to slide on the surface of the slide by the pull rod. When the lifting frame moves, it pushes the circular groove rod to move through the cross, and the molybdenum strip is pushed up and down inside the processing chamber by the circular groove rod. When the molybdenum strip is cleaned inside the processing chamber, the circular groove rod pushes the molybdenum strip to shake, so that impurities on its surface can fall off quickly during cleaning, thereby improving the cleaning effect of the molybdenum strip.

[0015] After the molybdenum belt of the present invention is wound around the surface of the circular groove rod, the elastic rod will push the connecting plate to move toward the surface of the circular groove rod through elastic force. When the connecting plate moves, it pushes the rolling rod to squeeze the molybdenum belt through the right-angle plate, so that the molybdenum belt will fit tightly to the surface of the circular groove rod, thereby improving the stability of the circular groove rod in limiting the molybdenum belt and avoiding the molybdenum belt from getting stuck due to deviation when moving inside the processing chamber.

[0016] When the rolling rod of the present invention squeezes the molybdenum strip, the right-angle plate will squeeze the inclined surface block through the pressure plate. After being squeezed, the inclined surface block will push the cylindrical rod to move inside the limiting hole. When the cylindrical rod moves, it squeezes the molybdenum strip through the scraper, so that the scraper can fit the surface of the molybdenum strip. When the molybdenum strip moves on the surface of the circular groove rod, the scraper will clean the impurities on the surface of the molybdenum strip during the movement of the molybdenum strip, and the cleaning effect of the molybdenum strip is improved by scraping. The scraper located inside the nickel plating cavity contacts the molybdenum strip, and the nickel plating liquid is evenly applied to the surface of the molybdenum strip through the scraper, so as to avoid uneven thickness of the nickel plating layer on the surface of the molybdenum strip.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the roller 171 squeezes the molybdenum strip 7, the right-angle plate 172 squeezes the inclined block 211 through the pressure plate 212. After being squeezed, the inclined block 211 pushes the cylindrical rod 201 to move inside the limiting hole 145. When the cylindrical rod 201 moves, it squeezes the molybdenum strip 7 through the scraper 202 so that the scraper 202 can fit against the surface of the molybdenum strip 7. When the molybdenum strip 7 moves on the surface of the circular groove rod 144, the scraper 202 cleans the impurities on the surface of the molybdenum strip 7 during its movement.The cleaning effect of the molybdenum strip 7 is improved by scraping, and the scraper 202 located inside the nickel plating chamber contacts the molybdenum strip 7, and the scraper 202 evenly applies the nickel plating liquid to the surface of the molybdenum strip 7 to avoid uneven thickness of the nickel plating layer on the surface of the molybdenum strip 7.
