Embodiment Construction

[0080] Next, preferred embodiments of the present invention will be described in detail. In addition, the present embodiment described below does not unduly limit the content of the present invention described in the claims, and all the configurations described in the present embodiment are not necessarily essential as solutions of the present invention.

[0081] 1. Outline of surface treatment equipment

[0082] figure 1 It is a longitudinal sectional view of a surface treatment apparatus such as a continuous plating treatment apparatus. In the continuous electroplating processing apparatus 10, a plurality of transport jigs 30A that respectively hold workpieces 20 such as circuit boards are aligned with the figure 1 Circular transport in the direction perpendicular to the paper surface. exist figure 1 In , two parallel linear conveyance paths 110 and 120 in the circular conveyance path 100 are shown. These two linear conveyance paths 110 and 120 are connected at both end...

Abstract

The invention provides a workpiece holding jig and a surface treatment device. Both surfaces of a workpiece are treated by energizing the workpiece. The workpiece holding jig includes: a fixed clamping piece fixed to a conductive member in an electrically insulating manner; a movable clamping piece which can swing freely relative to the fixed clamping piece; and a plate spring that maintains a clamped state of the workpiece clamped by the fixed clamping piece and the movable clamping piece, the plate spring including: a first fixed portion that is fixed by being electrically connected to the movable clamping piece; a second fixing portion which is electrically connected with the conductive member and is fixed; a third fixing portion which is electrically connected with the fixed clamping piece and is fixed; and a pair of arm portions connecting the first fixing portion and the second fixing portion, the second fixing portion being located between the first fixing portion and the third fixing portion in the longitudinal direction of the leaf spring, and a portion of the pair of arm portions disposed on both sides of the fixed clamping piece and the movable clamping piece in plan view including a U-shaped bent portion.

Description

[0001] This application is a divisional application for an invention patent application with the application date: September 27, 2017, application number: 201780060162.6 (PCT / JP2017 / 034923), and the invention name is "workpiece holding fixture and surface treatment device". technical field [0002] The present invention relates to a workpiece holding jig, a surface treatment apparatus, and the like used in a surface treatment apparatus such as a continuous plating apparatus. Background technique [0003] In a surface treatment apparatus such as a continuous plating apparatus, a workpiece is held down by a workpiece holding jig, and the workpiece is continuously conveyed in the liquid in the surface treatment tank. For example, as shown in Patent Document 1, the workpiece holding jig generally clamps the upper end of the workpiece to hold the workpiece sagging. [0004] In addition, another function of the workpiece holding jig is to set the workpiece as a cathode (cathode) w...
