Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger used for a plating process of a plate body such as a printed wiring board, a dipping process such as a cleaning process, and the like. An object of the present invention is to provide a hanger that can be easily held by a body.

[0002]

2. Description of the Related Art For example, in a process of manufacturing a plate body such as a printed wiring board, there are many immersion steps of immersing a plate to be processed in a processing solution such as a plating solution or a cleaning solution.

In these immersion steps, the treatment is carried out by a method called a badge treatment in which immersion tanks are continuously arranged and immersed sequentially. Therefore, in order to efficiently process a large number of plates to be processed, the plates to be processed are held on hangers in a vertically standing state.

[0004] As shown in FIG.
A guide 12 for sandwiching the plate 3 to be processed is disposed at a fixed interval between the lower frame 4b and the two lateral frames 4c of the plate supporting member 1, and the plate 3 is inserted along the guide 12. The plate 3 can be held by the plate supporting member 1 while being held by the guide, and the plate 3 can be held by the clamp 5 provided on the upper frame 4a.

However, since the above-mentioned hanger holds and holds the plate to be processed by the guide, if the plate to be processed is warped, it may come off the guide and collide with the inner wall of the immersion tank or fall from the hanger. there were. In addition, when the size of the plate to be processed is different, it is necessary to adjust the size of the plate to be processed by moving the position of the horizontal frame.

[0006] Further, in recent years, as the thickness of the plate to be processed has been reduced, the tendency has been remarkable, and it has been difficult to hold the plate with the above-mentioned guide.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and enables a thin plate to be easily gripped even if it is warped, so that the plate does not fall and is stable. It is an object of the present invention to provide a hanger that can be immersed.

[0008]

According to a first aspect of the present invention, there is provided a hanger having at least two clamps disposed on each of the upper and lower frames of a plate supporting member, the hangers and the clamps holding the plate by the clamps. The fixing member of the clamp is supported by a plate supporting member, a link pivotally supported is provided in the middle of the fixing member, and a movable member for gripping the plate is provided at one end of the link. And

According to a second aspect of the present invention, in the hanger of the first aspect, the movable member for holding the plate is formed of a conductive material, and the contact surface for holding the plate is smooth. It is characterized by being.

A hanger according to a third aspect of the present invention is the hanger according to the first aspect, wherein the link is formed in a coil shape.

In the present invention, since the movable member and the fixed member for gripping the plate are arranged via the link, the plate can be easily gripped by operating the operation section of the link. Further, since the movable member is formed of a conductive material, it is possible to secure conductivity with the plate body to be gripped and to easily conduct electricity.

[0012]

Embodiments of the present invention will be described below.

FIGS. 1 and 2 show an embodiment of the present invention.
FIG. 1 is a perspective view showing an embodiment of the hanger of the present invention.
FIG. 2 is an enlarged view of a main part of the embodiment of FIG.

As shown in FIG. 1, the hanger of the present invention comprises:
It is composed of a plate supporting member 1 for holding a plate 3 and a frame supporting member 2 received on the side wall of an immersion tank immersed at both ends thereof.

Since the plate supporting member 1 holds a plate 3, which is a plate to be processed, for example, an inner layer plate which is a material of a printed wiring board, its outer frame 4 is larger than the outer shape of the inner layer plate to be held. Has become. Therefore, the outer frame 4 has a rectangular shape, and at least two clamps 5 are arranged at positions facing the upper and lower frames 4a. In the figure, four hangers are arranged at the top and bottom, respectively. The position where the clamp 5 is disposed is a position where the plate 3 can be stably held, and it is preferable that the clamp 5 is disposed at a position symmetrical to the left and right. Further, the clamp 5 can slide according to the size of the plate 3. Is preferred.

The clamp 5 is provided on the plate supporting member 1.
, And a movable member 7 for gripping the plate 3. The fixed member 6 and the movable member 7 are mutually connected via a link 8 that is pivotally supported in the middle of the fixed member 6. Are linked.

FIG. 2A is an enlarged view of the clamp, which is holding a plate. As shown in the figure, a fixed member 6 is engaged with the plate supporting member 1, and a movable member 7 is connected via a link 8. The movable member 7 has a substantially T-shaped main body, a contact portion 9 for gripping the plate body 3, and an operation unit 1 for performing an operation for gripping the distal end of the main body extending in three directions.
0, and a rotating portion 11 that is supported by a fixed member 6 to assist the link 8. A link 8 pivotally supported in the middle of the fixing member 6 is rotatably supported by the operation unit 10. The contact portion 9 is made of a conductive material such as copper so that the contact surface is smooth so as to grip the plate 3 and the plate 3 can be energized. The contact portion 9 is electrically conducted by the frame supporting member 2 and can conduct electricity with the plate 3 at the time of electrodeposition such as plating.

Therefore, the movable member 7 can be turned around the turning portion 11 by operating the operating portion 10, and the contact portion 9 and the fixed member 6 or the plate supporting member 1 are linked by the link 8. The plate 3 can be held in a state of being gripped by a part thereof.

FIG. 2 (2) shows another embodiment of this clamp, in which the link 8 is formed in a coil shape in the embodiment of FIG. 2 (1).

When the link 8 is formed in a coil shape as described above, the action of pulling the movable member 7 is involved, and when the plate 3 is gripped, the gripping force increases and the plate 3 is not dropped. And the contact portion 9 is held without gripping the plate 3.
When is open, a force acts so as to hold the open state.

To hold the plate 3, the plate 3 is placed on the opened contact portion 9, and the operating portion 10 is further operated to hold the contact 9 against the plate 3. be able to.

As described above, since the clamps are respectively disposed on the upper and lower frames of the plate supporting member, if the plate is gripped by the respective clamps, even if vibration is applied to the hanger during conveyance, The body can be stably held without falling.

[0023]

As described above, in the hanger of the present invention, the clamps are respectively arranged on the upper and lower frames 4 of the plate supporting member, and the fixing member 6 of the clamp is supported by the plate supporting member. And the movable member are pivotally supported via the link 8, so that the plate body can be reliably gripped, and the plate body does not drop even if vibration is applied to the hanger being transported. Even if the body is warped, it can be stably held. Furthermore, even if the thickness of the plate body varies, it can be reliably held by the link 8.

Further, since the contact portion is formed of a conductive material and is smooth, the gripped plate body and the contact portion are in close contact with each other, so that current can be easily supplied to the plate body and stable by electrodeposition plating or the like. Immersion treatment can be performed.
