A method for rinsing a treatment cell of a workpiece surface treatment system, which obtains a surface-treated workpiece by sequentially carrying the treatment cell containing the workpiece to a series of apparatuses for operations in the respective apparatuses is provided. A surface treatment apparatus performs a surface treatment on the workpiece by receiving the treatment cell from a carrying apparatus and supplying a surface treatment liquid to the inside of the treatment cell while rotating the treatment cell. A workpiece collection apparatus collects the workpiece by receiving the treatment cell from the carrying apparatus, inverts the treatment cell, and squirts the inside of the treatment cell with water from below to flow out the workpiece. The carrying apparatus carries the treatment cell to the surface treatment apparatus, and then to the workpiece collection apparatus.

Workpiece surface treatment system

Inside a single apparatus main body (), a surface treatment apparatus includes: a treatment cell (); a vertical rotation shaft (); an attachment/detachment device; a receiving tank (); a cover body (); a plurality of tanks (); a plurality of surface treatment liquid supply devices (); a cleaning water supply device; a drain device (); and a first cleaning device. Upon operation of the surface treatment liquid supply device while the treatment cell () containing small objects is rotated by the vertical rotation shaft (), a surface treatment is carried out on the small objects, upon operation of the cleaning water supply device, the small objects inside the treatment cell () are cleaned, and upon operation of the first cleaning device, the inner face of the cover body and the outer face of the treatment cell are cleaned, thus providing circulation use of surface treatment liquids in the tanks.

Surface treatment apparatus

The surface treatment apparatus includes: a supply device for supplying an introduced workpiece to the inside of a treatment cell of a subsequent surface treatment device; a surface treatment device for supplying a surface treatment liquid to the inside of the treatment cell while rotating the treatment cell, thereby performing a surface treatment on the workpiece; a workpiece collection device for inverting the treatment cell, and squirting the inside of the treatment cell with water from below to flow out the workpiece, thereby collecting the workpiece into a collection vessel; a drying device for receiving the collection vessel from the workpiece collection device, and exposing the workpiece within the collection vessel to air, thereby drying the workpiece; and a carrying device for carrying the treatment cell between the surface treatment devices, and between the surface treatment device and the workpiece device, wherein the surface treatment apparatus includes the one or more surface treatment devices.

A workpiece surface treatment system (), which obtains a surface-treated workpiece by sequentially carrying a treatment cell () containing a workpiece to a series of apparatuses for operations in the respective apparatuses, is characterized by including: a carrying apparatus () for sequentially carrying the treatment cell () to a series of the apparatuses in the system; a carrying-in/out apparatus () for carrying the treatment cell in and out of the carrying apparatus; a surface treatment apparatus () for performing a surface treatment on the workpiece by receiving the treatment cell from the carrying apparatus and supplying a surface treatment liquid to the inside of the treatment cell while rotating the treatment cell; and a workpiece collection apparatus () for collecting the workpiece by receiving the treatment cell from the carrying apparatus, inverting the treatment cell, and squirting the inside of the treatment cell with water from below to flow out the workpiece, wherein the carrying apparatus carries the treatment cell to the surface treatment apparatus, and then to the workpiece collection apparatus.

A plating process apparatus () for small objects, including a treatment cell () formed by combining a base plate (), a bottom plate (), an electrode ring () and a cover () using bolts (), energizes a plating solution within the treatment cell () while bringing the small objects () into contact with the electrode ring () and circulating the plating solution () from the inside of the treatment cell () to the outside thereof through a flow-out means by rotating the treatment cell () with a vertical rotation shaft (), thereby plating the small objects (). The apparatus () is characterized in that the flow-out means is a gap channel formed between adjacent sheet members () by sandwiching the sheet members (), each having a dimension smaller than a minimum dimension of each small object (), between the bottom plate () and the electrode ring () circumferentially at appropriate intervals.
