Description

  The present invention relates to a plating barrel apparatus that performs a plating process.

  One of the plating equipment used when plating objects to be plated (workpieces) with small dimensions such as electronic parts is equipped with a barrel that accommodates the object to be plated and a cathode provided in the barrel, and is rotatable. The object to be plated is accommodated in the supported barrel, and a voltage is applied between the anode on the plating solution side and the cathode while the barrel is immersed in the plating solution, and the barrel is rotated about the rotation axis. There is a plating barrel apparatus that performs a plating process by being driven.

  Among these barreling apparatuses for plating, a plating barrel apparatus in which a net-like sheet is stretched on a barrel frame is conventionally known as a means for performing a plating process on a particularly small object to be plated.

  In such a barrel apparatus for plating, since it is easy to form a mesh of a mesh sheet small compared to the case of forming a small hole in a panel, even if the object to be plated is small, it is caught. However, while the plating process can be stably performed with high quality, the repetitive plating process causes a problem that the mesh sheet is deteriorated to bend and the quality of the plating process is lowered.

  In order to improve this problem, a prismatic barrel frame whose axis direction is decentered with respect to the same axis as the rotation axis or the rotation axis connects between the pair of opposed panel portions and the pair of opposed panel portions. Three or more connecting frame portions that extend in the axial direction and are arranged around the axis so as to be fixed between the adjacent connecting frame portions in a detachable manner. A plating barrel apparatus disclosed in Patent Document 1 in which a mesh sheet can be replaced is known.

The both end portions of the peripheral wall panel 7 on the side of the connecting frame portion 12 are formed in a tapered shape so as to be fitted between the pair of contact surfaces 29 having a tapered shape.

  Eleventh, the opposing panel portion 11 and the connecting frame portion 12 are separately formed, and the barrel frame 4 can be assembled.

  According to the above configuration of the present invention, the contact surface with the inner surface side of the peripheral wall panel is formed as a non-convex surface. Therefore, when the mesh sheet is disposed and fixed between the contact surface and the peripheral wall panel, the contact surface is Compared with the case of projecting convexly toward the peripheral wall panel, wrinkles are less likely to occur in the mesh sheet, and the mesh sheet can be stably attached and fixed.

  In addition to fixing the mesh sheet on the inner surface side of the peripheral wall panel by inserting and fixing the peripheral wall panel integrally attached in advance between the connecting frame portions, the mesh sheet is further simplified.
