The configuration will be described in detail with reference to the accompanying drawings showing the following.

A large number of overflow shaft cylinders 3 having overflow holes 2 for overflowing silver nitrate 1 upward are arranged and erected on a machine base 4.

A lifting rod 5 is vertically installed above this overflow shaft cylinder 3 so as to be able to rise and fall freely.

A suction cylinder 6 is pivotally attached to the lower part of the lifting rod 5 so as to be able to be turned upside down.

A large number of suction cylinders 8 having an outer diameter slightly smaller than the outer diameter of the element body a and provided with suction holes 7 are vertically disposed on the lower surface of the suction cylinder 6, facing the overflow cylinder 3.

A take-out plate 10 having a plurality of insertion holes 9 which are tightly fitted into the suction shaft cylinder 8 is detachably attached to the lower surface of the suction cylinder 6.

A supply plate 12 having a plurality of storage holes 11 for storing the element bodies a stacked in multiple layers is interposed between the suction shaft cylinder 8 and the overflow shaft cylinder 3 so as to be slidable left and right.

In this figure, a drill press-shaped support body 13 is erected at the rear of the machine base 4, and an elevating rod 5 is installed vertically at the front of the support body 13 so as to be able to rise and fall freely. The figure shows one that can be moved up and down by operation.

In addition, the upper and lower limit stoppers are installed internally.

The suction cylinder 6 in this figure has a concave support frame 15 at the bottom of the lifting rod 5.
is fixed, fulcrum pins 16 are provided horizontally protruding from the left and right sides of the support frame 15, and the suction cylinder 6 is pivotally attached to the fulcrum pins 16 so as to be able to be turned up and down.

Reference numeral 17 denotes locking pins that are inserted through the support frame 15 and the crosspieces 18 fixed to the left and right sides of the suction cylinder 6 to prevent the suction cylinder 6 from being reversed.

Reference numeral 19 indicates a suction source (vacuum generation source) that communicates with the inside of the suction cylinder 6.
This is a more extended suction hose.

The take-out plate 10 shown in this figure is made of paper or plastic, and has pressure rods 20 attached to four locations on the lower surface of the suction cylinder 6.
is loosely inserted, a press plate 21 is fixed to this press rod 20, and a spring 22 is provided that biases the press rod 2o in a direction in which the take-out plate 10 is sandwiched between the lower surface of the suction cylinder 6 and the press plate 21. Board 10
In the figure, the take-out plate 10 is detachably attached to the lower surface of the suction cylinder 6 so that the press plate 21 is rotated laterally to take out the suction cylinder 6.

The supply plate 12 in this figure is made of plastic.
A guide frame 23 is horizontally installed in the guide frame 23.
A supply plate 12 is slidably installed on the top.

Further, this figure shows a case where a large number of takeout plates 10 are attached to the lower surface of the suction cylinder 6.

Previously, a large number of elements were lined up one by one on a board surface, and in this state silver oxide was applied to the elements with a brush, but the elements were made to be extremely thin and light; Since it is easily broken, it is quite difficult to apply it with a brush, and it is also extremely difficult to apply it to a uniform thickness, which significantly reduces work efficiency.

The present invention eliminates these drawbacks at once, and since it is constructed as described above, it has the following features.

1. A large number of element bodies a are stacked and stored in the storage hole 11 of the supply plate 12 in a multi-layered manner, a take-out plate 10 is attached to the lower surface of the suction cylinder 6, and in this state (Fig. 1) the supply plate 12 is overflowed. A slide is inserted between the flow axis cylinder 3 and the suction axis cylinder 8 (FIG. 3), and the lifting rod 5 is lowered to lower the suction axis cylinder 8 to a position close to the element body a.

Then, due to the suction action of the suction hole 7 of the suction shaft cylinder 8, the element a
is attracted to the lower end surface of the suction shaft cylinder 8.

When the element a is adsorbed to each suction shaft cylinder 8, the lifting rod 5 is raised to position the suction shaft cylinder 8 upward.

In this state, slide the supply plate 12 away (Fig. 4)
.

Then, the lifting rod 5 is lowered again to lower the suction shaft cylinder 8 to a position close to the overflow shaft cylinder 3.

Then, the element a adsorbed to the lower end surface of the suction barrel 8 may overflow from the overflow hole 2 of the overflow barrel 3 (it may be in a swollen state due to surface tension or in a slightly overflowed state).

), and as a result, silver nitrate 1 is applied to one side of the element body a.

Once the silver nitrate 1 has been applied, the lifting rod 5 is raised and the suction cylinder 8
position above.

Next, the suction cylinder 6 is turned upside down (FIG. 2).

In this state, the extraction plate 10 attached to the suction cylinder 6 is lifted horizontally and removed.

Then, the element a is placed on the take-out plate 10, and in this state, the element a is
can be taken out.

Then, the element body a is naturally or forcedly dried.

After drying, the cloth coated on one side is stored in the storage hole 11 with the coated side facing upward.

Then, repeat the above operation again to coat the other side with silver nitrate 1.

Then, the element body a is naturally or forcedly dried.

Silver nitrate 1 is now coated on both sides of element body a.

Next, the element body a is baked in an electric furnace or the like.

Thus, the plated element a is completed.

Silver nitrate coating work can be performed simply by repeating a series of simple operations as described above, and the work efficiency is much improved compared to the conventional method.

2 In particular, unlike conventional brush or sponge application, the coating is applied by bringing the element a into contact with the overflowing silver nitrate 1, so the coating thickness of the silver nitrate 1 is uniform and constant, and the product is of high quality. can get.

3. Furthermore, since a large number of suction cylinders 8 and overflow cylinders 3 are arranged, silver nitrate 1 can be coated on many bodies a at once, and work efficiency is further improved.

4 Furthermore, since it has a simple structure, it is suitable for mass production and can be manufactured at low cost.

As described above, according to this study, silver nitrate coating on a porcelain capacitor element body has excellent practical effects such as being able to coat the element body of a porcelain capacitor (ceramic capacitor, etc.) with silver nitrate well and efficiently. The equipment will be provided.
