DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet-like product, such as a printed circuit board, which is suspended in a suspended state at the upper part of a product, and while the power is supplied at the upper part of the product, the processing liquid in the plating tank is advanced horizontally and horizontally. The present invention relates to a product guide mechanism for a sheet-shaped product in an electroplating apparatus for electroplating.

[0002]

2. Description of the Related Art An upper portion of a sheet-like product to be plated is held by a jig movably supported by a cathode bar in a suspended state, and the sheet-shaped product held in a suspended state by the jig is held by the jig. An electroplating apparatus for performing electroplating while advancing horizontally and horizontally in a processing solution in a plating tank along the cathode bar while supplying power from the cathode bar to the upper part of the product via the jig is used. I have. When a sheet-like product such as a printed circuit board or the like, in which the upper part of the product is suspended in a suspended state by the jig in the treatment solution in the plating treatment tank, advances horizontally in a horizontal direction, the sheet-like product has resistance to the treatment solution. It is difficult to maintain the expected advancing posture due to the swinging caused by the resistance caused by air agitation. For this reason, the product guide disposed with a small gap on both sides of the sheet of the sheet-like product so as to prevent the sheet-like product from advancing horizontally in the processing liquid horizontally. Is used.

[0003]

However, the conventional product guide is arranged so as to always shield the same horizontal position with respect to the sheet-like product advanced between the product guides. There is a problem that a uniform plating film is not applied to a sheet surface which is always shielded by the product guide and a sheet surface which is not always shielded. The product guide mechanism of the present invention has been provided in view of such circumstances, and can always guide the sheet-like product that is advanced between the product guides without blocking the same horizontal position, thereby providing a product guide. Therefore, the problem that a uniform plating film is not applied is intended to be eliminated.
