Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is generally applicable to a large number of components, such as pipes, rods, and plate materials, which are relatively small in size, lightweight, and have a complicated shape. The present invention relates to an improvement of an apparatus including a jig for hooking an object to be plated used for plating.

[Conventional technology]

2. Description of the Related Art Conventionally, as a hooking device for a plated object of this type, for example, as shown in FIG. 2, a frame-shaped conductive hanger (22) in which a large number of hooks (23) are arranged in a row is mounted on a support rod (21). In the attached state, the upper end portion of the support rod was hung on the current-carrying bar (24), and the current-carrying bar was conveyed between the electrodes on the plating tank side and bridged to perform the plating treatment.

[Problems to be Solved by the Invention]

However, in such a conventional hooking device, since the hooked object to be plated is always in the same position and in the same direction in the plating tank, the thickness of the plating film to be formed is large. Unevenness is likely to occur, and in the case of complicated product shapes, the accumulation of air in the interior causes non-adhesion of the plating, and further, when the processing liquid is pulled out from the plating tank, It is often taken out, and there is a problem that the processing liquid is wasted.

In order to solve the above-mentioned conventional problems extremely effectively, the present invention connects a hooking jig composed of a supporting frame for hooking and setting a conductive hanger in which a large number of hooks are arranged in a row to an external driving device. By the operation of a transmission mechanism having a connecting rod that follows the movable bar that reciprocates in the direction and converts it into a vertical movement, the connecting rod continuously moves to the left and right in the plating tank with the shaft core of the suspension rod as the supporting shaft. It is rotatably configured to promote uniform plating film formation, at the same time eliminates the fear of non-plating inside due to complicated product shape, and further, if desired, the plating in a state of being pulled up from the plating tank. To propose a device for hooking a workpiece to be plated, which can prevent the processing liquid from being brought out to the outside when it is pulled up from the plating tank by allowing it to rotate to the left and right outside the tank. The purpose is.

[Means for Solving the Problems]

The present invention relates to an energizing bar which is transferred by an external carrier and bridges between electrodes arranged near both ends in the longitudinal direction of a plating tank, and an energizing bar which is detachably attached to an external driving device on the upper side of the energizing bar. And a supporting beam parallel to the current-carrying bar for supporting a movable bar provided with a rack partly connected to and reciprocating in the horizontal direction for a predetermined distance, and the horizontal reciprocating motion of the movable bar on the current-carrying bar. Following this, a transmission mechanism for converting the rotation caused by the engagement with the rack portion into the vertical movement of the connecting rod is attached,
Further, a hooking jig composed of a substantially circular or polygonal support frame, in which a conductive hanger having a plurality of hooks arranged in rows is hooked and set on a flat surface, and the energizing bar has the shaft core of the hooking jig. The upper end of the suspension rod is fixed to the lower end of the suspension rod so as to be pivotable to the left and right, and a lead wire from the current-carrying bar to the conductive hanger is arranged, while the lower end of the connecting rod is hooked on the hook. A gist of a device for hooking a to-be-plated object to be plated, which is connected to a jig and configured to rotate the hooking jig to the left and right in a plating tank by following the reciprocating movement of the movable bar. It is a thing.

When bridged between the electrodes arranged near the ends, the pinion meshes with the rack (2 ') part by following the horizontal reciprocating movement of the movable bar (2) by the operation of the external drive device. With the rotation of (4), the vertical movement of the connecting rod (6) in the vertical direction is generated, and at the same time, the hooking jig (7) is rotated to the left and right.

If desired, after the plating process, the hooking jig (7) outside the plating tank upper tank in a state of being pulled up from the plating tank is installed on the protrusion wall (13) of the movable bar (2). By connecting to a driving device which is a separate external body, it is possible to cause lateral rotation outside the tank.

〔The invention's effect〕

As described above, the device for hooking a to-be-plated object to be laterally rotated according to the present invention is hung on the current-carrying bar (1) and transferred by the carrying device. Since it is configured to rotate to the left and right even outside the upper plating tank after the treatment, the horizontal rotation that is constantly repeated in the plating tank promotes the formation of a uniform coating film thickness. It is possible to improve the plating quality by eliminating the fear of non-plating inside due to the complicated product shape.
Further, it is a very useful right-and-left turning type hooking device for a plated object which can prevent the processing liquid from being brought out to the outside when it is pulled up from the plating tank and make the plating liquid economical.
