Description

[Detailed Description of the Invention] The present invention relates to a processing object transfer device for a plating processing apparatus, and is particularly intended to shorten the processing time for transferring the processing object under accurate transfer conditions.

Generally, in a plating treatment apparatus, a number of plating tanks are arranged in series below a transfer device that transfers the workpiece holder that holds the workpiece to be plated to a predetermined position. These plating tanks have different plating conditions depending on the workpiece to be plated, and the workpiece is plated in the plating tank according to the plating conditions, and then transferred to the next process.

Currently, a so-called carrier-type transfer device is generally known as a workpiece transfer device for such a plating processing apparatus. This carrier-type transfer device uses a carrier-type transfer device to transfer a workpiece that has been plated in a predetermined plating treatment tank to a post-processing process.
The carrier type transfer device returns to the pretreatment process and transfers the pretreated workpiece to a predetermined plating tank.

However, with such a carrier-type transfer device, after the workpiece that has been plated in a predetermined plating treatment tank is transferred to the post-processing process by the carrier-type transfer device, the carrier-type transfer device is transferred to the front plate again. It is necessary to return to the treatment process and transport the pretreated workpiece to a predetermined plating tank again, which has the disadvantage that a large amount of time is lost in transferring the workpiece.

The present invention was devised in order to solve the drawbacks of the conventional processing material transfer device, and is a processing material transfer device for plating processing equipment that can significantly shorten the processing material transfer time. The purpose is to provide the following.

The plating tank 5 is then transferred onto the vacant first plating tank 5. In this state, all the rails, that is, the first rail 13, the second rail 17, and the third rail 27, are lowered as shown in FIG. ing.

Next, the movable rail 22 corresponding to the sliding portion 11 of the predetermined object holding material 7 to be taken out from the plating tank 5 is advanced by the cylinder 25. In the embodiment shown in FIGS. 1 and 3, the movable rail 22 corresponding to the second plating tank 5 is advanced.

Next, when all the rails are raised in this state, as shown in FIG.
is engaged with the sliding part 11 of the object holding member 7, and the second
As shown in the figure, the workpiece 8 that had been immersed in the second plating tank 5 is taken out. that time,
The objects to be treated 8 that had been immersed in the pre-treatment tank 4 and the post-treatment tank 6 are also taken out at the same time.

After that, the other sliding parts 11 of the object holding material 7
The movable rail 22, which was in the retracted position so as not to engage with the rail, is moved forward by the cylinder 25 to align the entire rail. When the transfer belt 18 is rotated in the direction of the arrow with the rails aligned in this way, the locking piece 12 of the workpiece holding member 7 mounted on the second movable rail 22 and the moving one The pushing tool 21 is engaged with the workpiece holding member 7, and the pushing tool 21 moves the workpiece holding member 7 to the position where the pushing tool 21 is reversed, that is, the third rail 27 of the third transfer device 3.
sent to the top. At the same time, the other pushing tool 21 is engaged with the locking piece 12 of the workpiece holding material 7 mounted on the first rail 13 of the first transfer device, and the workpiece holding material 7 is moved to the vacant space. It is transferred along the second rail 17 to the top of the second plating tank 5.

In this state, all but the second movable rail 22 are moved backward, and in this state, the entire rail is lowered again to immerse the object 8 into the processing tank.

After being immersed for a predetermined time, the plated workpiece 8 is taken out from the third plating tank 5 and transferred to the post-treatment tank 6, and the pretreated workpiece 8 is emptied. Third plating treatment tank 5
, and repeat the above-mentioned operations in sequence.

Thus, the present invention has the above configuration, and according to the workpiece transfer device of the plating processing apparatus according to the present invention, as shown in the transfer process diagram in FIG. Since it is possible to transfer the pre-treated object to a predetermined plating treatment tank at the same time as transferring the object to the post-processing process, compared to the conventional transfer device whose transfer process diagram is shown in Fig. 9. This has the excellent effect of greatly shortening the transfer time of the processed material.

Further, the processing object transfer device of the present invention has the effect of being able to accurately transfer the processing object under stable transfer conditions.
