Description

[Detailed Description of the Invention] Industrial field of application The invention is applied to the surface of an object to be treated in electroless surface treatment, that is, chemical surface treatment such as electroless plating, pickling, neutralization, and water washing. By improving the contact conditions with the liquid, it is possible to uniformize the surface treatment of the object to be treated.

Conventional technology Conventionally, the driving force of a prime mover is transmitted to a shaft for attaching a workpiece immersed in a processing liquid, and the shaft is simply rotated or oscillated, or a combination of the two or stirring of the liquid is used. The uniformity of product quality is unsatisfactory because the contact conditions of the processing liquid to the object to be processed are non-uniform.

Problems to be Solved by the Invention The invention aims to improve the contact conditions of the processing liquid with the object to be processed (conditions for refreshing, removing generated gas, etc.) and to uniformize product quality.

Means for Solving the Problems In order to achieve the above object, a planetary gear device is assembled to a frame whose vertical piece extends and is fixed into the processing liquid in the tank when the device is installed at the upper edge of the processing tank, A fixed shaft that holds the object to be processed is fixed to an extension of the axis of the 'a star gear of the device, and the rotational force of a drive source disposed in the air above the frame is transmitted to the 'a star gear shaft. By holding and fixing the object to the fixed shaft and driving it, the object to be processed is rotated in the processing liquid with planetary rotation (revolution and rotation) according to the movement of the planetary gear. The structure is designed to ensure that the liquid comes in sufficient contact with the liquid.

1st Embodiment (See Figures 1 to 4) Figure 1 (part 1 longitudinal side view), Figure 2 (part 1 longitudinal □ front view), and Figure 3 show how the workpiece is attached to the expansion shaft. It is a drawing for explaining fixation.

In Figures 1 and 2, -1 is an electroless plating treatment tank;
2 is a plating solution (chemical solution), 3 is a frame installed at the upper edge of the processing tank, and a pair of device members 3a (
3b has a hook), and a vertical plate 3c is fixed to one side between both device members 3a, and is immersed in the processing liquid 2.

The rotational driving force of a drive source 4 disposed on one side of the device member 3a above the vertical plate 3C is transmitted to the vertical plate 3 via a drive gear 5.
The signal is transmitted to an intermediate gear 6 rotatably attached to the upper part of C and a driven gear 7 that meshes with the intermediate gear 6.

A first planetary gear 8 and a second planetary gear 9 are rotatably pivotally attached to a circular orbit position on the side surface of the driven gear 7. A center gear 10 is disposed between the second planetary gears 8 and 9 and meshes with the second planetary gears 8 and 9, respectively. The center gear 1O is fixed to the lower part of the vertical plate 3c (immersed in the processing liquid) of the frame 3 via a mounting shaft, and the driven gear 7 is attached to the part of the mounting shaft on the vertical plate 3c side.
is rotatably mounted.

Each of the planetary gears 8.9 has extended shafts 13.14 extending in the horizontal direction for mounting and fixing the objects 11 and 12 to be processed vertically at regular intervals.
．． 12 is immersed in processing liquid z. Expansion axis 13.1
4 consists of a main body a and a sliding piece, as shown in FIG. 3, and a wedge C can be inserted between them. Processed object 1
1゜12 is the main body a, by inserting the center hole into a number of recesses provided at regular intervals on the surface of the sliding piece, and then press-fitting the wedge C between both a and b. The moving pieces are pushed open, so each workpiece 11 and 12 is moved to the expansion shaft 1.
3.14 attached to 9. d is a wedge stopper.

To explain the operation, the rotational driving force from the driving source 4 rotates the intermediate gear 6 via the driving gear 5, and the driven gear 7 that meshes with the gear 6 rotates. As the driven gear 7 rotates, the first and second planetary gears 8 and 9, which are rotatably pivoted at circular orbit positions on the side surfaces of the driven gear 7, are moved to the frame 3.
The planetary gears 8.9 rotate (revolution) around the mounting axis of the center gear 10 while meshing with the teeth of the center gear 10 fixed to the vertical plate 3C via the mounting shaft. Each gear rotates around its own axis. That is, the above-mentioned No. 1. Due to the revolution of the second planet gear 8.9 (revolution around the attachment axis of the center gear 10), the expansion shafts 13. Objects 11 and 12 revolve in the liquid and also rotate. As mentioned above, in order to make the object to be processed revolve while rotating, it is necessary not only to mesh and rotate the gears, but also to
It is also possible to use pulleys and belts as in the embodiment (FIG. 4).

That is, the rotational force of the driving source 4 is transferred from the driving pulley 20 to the belt 2.
1, the driven pulley 22 rotatably attached to the vertical plate 3C is rotated. Pulleys 27 and 28 to which expansion shafts 25 and 26 for attaching objects to be treated are fixed are rotatably attached to the sides of 23° and 24, respectively. Further, a pair of pulleys 29.3 are provided at the extension of the mounting shaft of the driven pulley 22 to the vertical piece 3c.
The former fixed pulley 29 is connected to the rotatable pulley 27 and the latter fixed pulley 30 is connected to the rotatable pulley 28 by belts 31 and 32, respectively. Therefore, the rotation of the driving pulley a4 rotates the driven pulley 22 via the driving pulley 20, and the rotation causes the driven pulley 22 to revolve in a fixed circular orbit position. Further, the pair of fixed bullies 29, 30 rotates due to the rotation of the driven prini 22, and each bell h31.
As the pulleys 27 and 28 to which the workpiece attachments 25 and 26 are fixed to the side surfaces via the shafts 25 and 32 rotate, the mounting shafts 25 and 28 rotate.
The workpiece attached to 26 rotates around the revolution shafts 23 and 24.

In the invention with great effects, the workpiece mounting shaft, which is immersed in the electroless treatment liquid and has a large number of workpieces attached at regular intervals, revolves along an orbit, and the workpieces are Since the mounting shaft is also designed to rotate, the contact conditions of the processing liquid on the surface of the object to be processed can be made more uniform compared to conventional ones, and therefore the product quality can be improved.
