Plating processing line

Abstract

A plating processing line or system includes a plurality of surface processing apparatus including a surface processing apparatus for processing a surface of an object to be treated by introducing a treatment liquid to the surface, and a conveyer unit for conveying the object to be treated, which is disposed between the respective surface processing apparatus linearly or in a curved manner. Each of the surface processing apparatus includes a positioning unit for positioning the object to be treated, which has been conveyed by the conveyer unit to a predetermined position, at which the object is subjected to a pre-plating process or a plating process as a surface processing.

1 . A plating processing line comprising:
 a plurality of surface processing apparatus including a surface processing apparatus for processing a surface of an object to be treated by introducing a treatment liquid to the surface; and   a conveyer unit for conveying the object to be treated, which is disposed between the respective surface processing apparatus linearly or in a curved manner,   each of the surface processing apparatus including a positioning unit for positioning the object to be treated, which has been conveyed by the conveyer unit to a predetermined position, at which the object is subjected to a pre-plating process or a plating process as a surface processing.   
   
   
       2 . The plating processing line according to  claim 1 , wherein the surface processing apparatus includes: a degreasing heating apparatus which performs a degreasing heating process for removing oil from the object to be treated and for heating the object to a temperature for the pre-plating process; an electrolytic etching apparatus which performs an electrolytic etching process for etching the surface of the object; an anodization apparatus which performs an anodization process for forming an oxide film on the surface of the object; and a plating apparatus which performs a plating process for forming a plating film on the surface of the object, in which the degreasing heating apparatus, the electrolytic etching apparatus, the anodization apparatus and the plating apparatus are successively disposed from an upstream side toward a downstream side in the conveyance direction. 
   
   
       3 . The plating processing line according to  claim 2 , wherein the electrolytic etching apparatus, the anodization apparatus and the plating apparatus are configured to spray compressed air to a surface to be treated of the object and recover the treatment liquid adhering to the surface of the object after the electrolytic etching process, the anodization process and the plating process, respectively, and the surface of the object is then subjected to a water washing process. 
   
   
       4 . The plating processing line according to  claim 2 , wherein the anodization apparatus is allowed to perform or skip the anodization process depending upon a material forming the object to be treated. 
   
   
       5 . The plating processing line according to  claim 2 , wherein each of the electrolytic etching apparatus and anodization apparatus includes two chemical liquid tanks and configured to perform, in each of the electrolytic etching process and the anodization process, the treatment in one of the tanks at a time when the treatment liquid is renewed in another one tank. 
   
   
       6 . The plating processing line according to  claim 2 , wherein the same kind of treatment liquids having at least one of concentration and liquid temperature different from each other are respectively used in the electrolytic etching process and the anodization process, and the treatment liquids are switched to be supplied for each process so that the electrolytic etching process and the anodization process are performed in a single surface processing apparatus. 
   
   
       7 . The plating processing line according to  claim 2 , wherein a plurality of plating apparatus, which perform the plating process at the same time, are disposed on a downstream side of the electrolytic etching apparatus and the anodization apparatus. 
   
   
       8 . The plating processing line according to  claim 1 , wherein the object to be treated is a cylinder block of an engine, and the surface to be treated of the object is a cylinder inner peripheral surface of the cylinder block. 
   
   
       9 . The plating processing line according to  claim 1 , wherein the conveyer is a roller conveyer having a plurality of rollers disposed in parallel with each other so as to convey the object in a horizontal direction through rolling of the rollers.
