The suspension rod 4 is struck by the other end of the plate and is held by being pinched by each pair of pinching spring plates 8. Continuing, hanging rod 4
One end of the covering object 10 is pressed between each pair of sandwiched spring plates 8 and the other end is tapped to be pushed. Further, the hanging rod 5 is hung on the conductive rod 2, and is pressed against the other end of the intermediate covering object 10 between each pair of the sandwiched spring plates 8 and struck and held. Repeat this operation until the right covering object 10
Between the hanging rods 5 and 6, each pair of sandwiched spring plates 8
Hold in between.

In this way, the jig that has completed attaching and holding the object 10
A plating tank 11 indicated by a chain line by an automatic carrier (not shown)
Then, both hooking tools 1 are hooked on the cathode receiver 13 to immerse the object 10 to be plated in the plating solution 12 and the current is applied to apply plating.

When the plating is completed, remove the hooking jig from the plating tank 11 and
Remove each cover 10 as follows. Hanging rod 3
And 6 are knocked outward, and the object 10 held at one end by each pair of sandwich spring plates 8 of the hanging rods 4 and 5 is pulled out by hand. Then, the hanging rods 4 and 5 are tapped in the direction of increasing the distance to remove the remaining covering object 10.

In this way, the object to be covered 10
Repeatedly attach / detach to / from the hook jig according to the quantity.

[Problems to be solved by the invention]

In the conventional hooking jig for plating as described above, there is a problem that the plate-shaped covering object 10 needs to be attached and detached manually and the transport robot cannot be fully automated even though it is automated. . Further, since the hanging rods 3 to 6 are hit, the object 10 is often hit by mistake and the product is often damaged. In addition, there is a lack of certainty in the contact energization between the conductive rod 2 and the hanging rod 7. Furthermore, the object to be coated after plating
When removing 10, there was a hygiene problem that the worker was directly touched and damaged by the plating solution.

The present invention has been made to solve such a problem, ensures the conduction between the conductive rod and the hanging rod, and can easily attach and detach the plate-shaped covering object from the hanging rod, The purpose of the present invention is to obtain a hooking jig for plating that eliminates product damage, enables automatic attachment / detachment and enables automation, and improves productivity.

[Means for solving problems]

The hooking jig for plating according to the present invention has a plurality of movable holding contacts in which the conductive rods and the support rods, which are vertically arranged in parallel, are fixed to the lower portions of a pair of hooking tools arranged at intervals. The movable rod is movably supported by the tool, and the conductive rod is pressed into contact with the movable rod so that the movable holding contact member is fixed to the hanging rod. Attaching the elastic picking tool of, each picking tool is a fixed receiving plate fixed to one surface of the hanging rod, a spring member fixed to the other surface of the hanging rod at a position corresponding to each fixed receiving plate, The movable holding plate is fixed to the other end of the spring member and has a tip portion facing the tip portion of the fixed receiving plate and holding a plate-shaped adherend.

[Action]

In the present invention, each movable holding contactor supported by the support rod is moved to an arbitrary position so that the hanging rods are spaced from each other according to the width of each adherend. Place the hooking jig horizontally, resist the spring pressure from above the rear end side of each movable sandwiching plate,
It is pushed down all at once by the pushing means, and the tips are opened upward.
Therefore, a plurality of plate-shaped attached plates are vacuum-sucked in a horizontal posture with a predetermined interval, and both ends are inserted between the corresponding tip ends of the fixed receiving plate and the movable holding plate of each elastic cutting tool, By releasing the pushing down of the pushing means, the fixed receiving plate and the movable holding plate sandwich and hold. Raise the hooking jig in this state vertically, and make the plating in the plating tank. After finishing the plating, return to the horizontal posture and remove each covered object at the same time in the reverse order of the above procedure.
