is fixed and supported at both ends.

3 to 6 are made of a conductive material, and a hook 7 is formed at the upper end.
A plurality of (four in the figure) hanging rods 8 hooked to the conductive rod 2 are temporary clamping springs on both sides fixed to the hanging rods 3 to 6 at a plurality of locations.

This clamping spring plate 8 portion is shown in a bottom view in FIG. A pair of clamping spring plates 8 are fixed to both sides of the hanging rods 3 to 6 by rivets 9, and a plate-shaped object to be plated] O is clamped between the opposing tips of both clamping spring plates 8. is retained.

The operation of the conventional hooking jig described above is as follows.

First, suspend the suspension rod 3 from the conductive rod 2, press one end of the plate-shaped object to be plated between the spring bars 8, and tap the opposite end to push it in.Next, Suspend the suspension rod 4 from the conductive rod 2, press it against the other end of the object to be plated 10 between each pair of clamping spring plates 8, strike the suspension rod 4, and clamp it with each pair of clamping spring plates 8. is retained. Subsequently, the object to be plated 1 is placed between each pair of clamping spring plates 8 of the hanging ladder 4.
Press one end of o, tap the other end and push in.0 Furthermore,
A rod 5 is lowered onto the conductive rod 2, and pressed against the other end of the intermediate object to be plated 10 between each pair of clamping spring plates 8, and the clamping is held by tapping. By repeating this operation, the object to be plated 10 on the right side is suspended between i'I5 and 6, and held between each pair of clamping spring plates 8.

The jig that has completed mounting and holding the object 10 to be plated is carried into the plating tank 1 shown by the lead line by an automatic conveyance machine (not shown), and the hooks ↓t1 on both sides are connected to the cathode receiver 3. The hook immerses the object 10 to be plated in a plating solution 12 and applies electricity to plate it.

When plating is completed, the hooking jig is taken out from the plating tank]1, and each plated object 10 is removed by performing the following steps.

Knock the hanging rods 413 and 6 outward, and remove by hand the hanging objects 413 and 6 held at one end by the pair of clamping spring plates 8 of each of the hanging rods 4 and 5. Next, hanging rod 4
, 5 in the direction of increasing the spacing, and the shallow plating target 1
Remove 0°.

In this way, before and after plating work,
0 to and from the hooking jig repeatedly according to several companies.

[Apex while the invention is trying to solve]

The conventional plating hooking jig as described above has the problem that manual work is required to attach and detach the plate-shaped object 10 to be plated, and even though the transfer robot is automated, it cannot be fully automated. Furthermore, since the lowering rods 3 to 6 are struck, the object to be plated 10 is often accidentally struck directly, resulting in damage to the product. Moreover, the contact energization between the conductive rod 2 and the hanging handle 7 lacks reliability. Furthermore, there is a hygienic problem in that when removing the plated object after plating, the worker may directly touch it and be damaged by the plating solution.The present invention aims to solve this problem. This is done between the conductive rod and the hanging rod! Ensure electricity 1
cL, the purpose is to obtain a hooking jig for plating that can easily attach and detach plate-shaped objects to be plated from a hanging rod, eliminate product damage, enable automatic attachment and detachment, enable automation, and improve productivity. It is said that

[Failure to solve the problem]

The fitting consists of a fixed receiving plate fixed to one side of the hanging rod,
A spring member is fixed to one hill corresponding to each fixed receiving plate on the other surface of the hanging rod, and a plate-shaped object to be plated is fixed to the other end of the spring member with the tip facing the tip of the fixed receiving plate. [Function] In this invention, each movable holding contact tool supported by a support rod is moved to an arbitrary position, and is moved according to the width of each object to be clamped. The suspension rods are spaced from each other.

The hooking jig is placed horizontally, and each of the movable pincers resists the spring pressure from above on the rear end side of the plate, and is simultaneously pushed down by the push-down means to open the tip portion upward. Therefore, a plurality of plated plated plates are placed in a horizontal position at a predetermined interval and the ingredients are vacuum-adsorbed, and each elastic sandwicher is placed between the fixed receiving plate of the ingredient and the movable sandwicher is placed between the corresponding tip of the plate. By releasing the depression of the pressing means, the fixed receiving plate and the movable clamping member are held together by the plate. Raise the hooking jig in this state vertically and plate it in the plating bath.

After plating, return to the horizontal position and remove each plated object at once by reversing the steps above.
